Firing rolling – useful lesson for any physically strong healthy man. But sometimes there are large amounts of firewood that it is necessary to prepare in a short time, in this case use a special tool. Drovokol is a device without which it is difficult to do without having to chop massive wooden rolls.
Features of self-made models
Drovokol is especially necessary in private household, where you have to give a house using firewood. You can make a similar tool with your own hands, it is easy and will save a significant amount of funds. Working with a massive tree is a pretty risky business, you can get injured, the poet should use a good tool, observing the necessary safety instructions.
Mechanical units that help split wooden arrays and heavy logs, have the property of accumulating energy, they are economical, they are easy to manage. In working with such devices does not need muscular. The aggregates can cope with any logs and wooden bars. Work in pressure and can be controlled with logs up to 35 cm long, no physical effort is required.
Pressure tools have a DVS drive, and can also be connected to the electric motor. They are not cheap, but with their use practically completely excluded muscular efforts that need to be spent. Using this device, you can make a house up to 350 square meters, while frosts can be Siberian, up to -35 degrees Celsius.
This unit is safe, it is possible to indicate a fairly difficult design and great energy consumption.
The reverse stroke of the pusher is usually no more than 7 centimeters per second. For a few hours you can prepare one person more than halftone firewood. It is impossible to work with wet wood, it is recommended to lay wooden blanks in a rainfront under a canopy. For months for three Tree “Suit” to the desired Condition.The raw tree does not give a sufficient amount of heat, the thermal conductivity is much lower (by 25%), the column in it often gets to remove it from there sometimes it is sometimes extremely difficult. Homemade woodcut can be done no worse than the factory, that is, there will be a horizontal and vertical filing of the workpiece.
For orientation, it is worth saying what could be approximate cash savings:
- A good unit operating on diesel fuel and intended for the splitting of shushhek 25 cm in diameter, costs from 20 thousand rubles;
- The machine that can “frame” with the billets up to 35 cm, splitting them on 4-5 fragments, costs about 30 thousand rubles.
The simplest design of the woodcut is an ax Colon. To work with it, you need a certain practical experience. For woodcutters with experience, the column can be the main tool when processing wooden massive blanks, the sizes of the axle of this tool to one meter. Recent years, the colon is made from innovative materials, which allows you to more effectively use it in the work process.
A truck from a light durable material of Fibergles allows you to work with this tool more efficiently. In two thousand years, while there is a colon ax, he continuously improved. The axle from the modern Fibergles completely eliminates the vibration, painful returns to the palm.
To harvest firewood in large quantities, a push-type firewood is usually used. They have a whether or hydraulic pusher. A similar device pushes a massive wooden billet to the column, one, in turn, splits it into several small parts. The feed rate of the workpiece is about 5 centimeters per second. Vertical design woodwaves have a greater margin of safety, and they are more compact. The disadvantage of this device is that there is a risk of a blank emission, in which there are such “difficulties”:
- a lot of layers;
- Many bitch;
- There are various irregular spears.
Rover horizontal safer. The employee does not risk falling under the fluttering chip, because the speed is sometimes very high. The vertical unit has a circular broker of fragments, therefore, in terms of security, there are questions to this aggregate. Hydraulic woodcut:
- spends minimum energy;
- Safe in functioning
From the disadvantages should be specified: to work with such a device you need a certain experience. And also at high loads, the liquid can flow from the machine. In maintenance, the unit is simple, spare parts for it can always be found in the market.
The hydraulic woodwood has no return spring, as well as a fairly long time to switch – about 0.55 seconds. The time interval is quite significant, because the workpiece can split and get enough on many fragments. Such woodcases have a general drawback: the engine works through the hydrumuft and sometimes does not cope with the loads. The engine usually works in standard mode, while consuming some fuel. To the flywheel joins the engagement (it is usually hydraulic, there is also a fractional). This lever is a clutch with a pusher that provides chocks for the knife Colon.
Energy is enough completely to split almost any wooden chill.
Tools and materials
To create a screw colon, you will need:
- Power supply from 1.5 kW;
- shaft with a raised bearing;
- drive belt;
- cut cone;
- Metal 6 mm thick;
- Corners 6, pipes 45 mm.
We will need tools:
- welding machine;
- a hammer;
- Roulette and triangle line.
How to do?
Before starting work, you need to prepare drawings and instructions for assembling. Simple woodcut with an electric motor can be collected at home. Indicatively in this respect hydraulic woodwood, which can be done in the garage. Hydrosystem can be supplied from a mini excavator or some other technique. Performance will be determined by the effort of splitting:
- 20 cm half – 2 TC;
- straight layer – 2.7 TC;
- 25 cm – 2.4 TC;
- 30 cm on 4 parts – 4 TCs;
- 30 cm on 8 parts – 5 TC;
- 40 cm on 8 parts – 6 TC.
The power of the hydraulic pump is determined by the feed rate, which is on average 4.5 cm. Then the efficiency is calculated and the engine is selected, its stock must be 15% more.
And also with the reserve the fittings are selected;
An important working element is the Colon itself. It is made of durable metal (spring springs or rail, for example). The preparation is usually encountered a vertical knife, which is sharpened on a straight line (symmetrical wedge). Horizontal knife is a little further (18 cm), it is spent on the top oblique wedge.
A vertical knife for better safe operation is overlapped, the height of about 35 mm, and the tool performs 25 mm. This design will allow working with complex wooden elements, provided if they are placed smooth sideways at the bottom. Sharpening angles are made as follows:
- The vertical knife is designed for soft wood – 19 degrees (three thicknesses of the knife);
- for solid wood (including birch) – 15 degrees (3.8 knife thicknesses);
- horizontal knives – 16 degrees;
- The drummer has an angle of inclination no more than 26 degrees (minimum 20 degrees), the thickness of the knife is 2.6;
Warm cutter works easier, it is cheaper than the hydraulic unit (it is not more expensive than 20 thousand rubles). Make it yourself not very difficult. The pusher is supplied with the use of a toothed rail, the transfer link on the shaft works with such a calculation so that the movement occurred not more than 4.5 cm per second. To make, items are needed – enough to disassemble the old jack. Wood cutter does not have hydraulic nodes, its service takes a minimum of time.
Such an aggregate, in terms of safety, more preferable. The scheme of work is this: acts when lowering the lever, then the return spring element will raise the rail and fold it back. The lack of such an aggregate is that with a decrease in the feed rate, the emphasis is growing rapidly, and then it also suddenly falls to zero. If the billet is a cavity or some other flaw, the unit will be exposed to too much load, it may be spontaneously, which can provoke the deformation of the machine or even its breakdown.
The hydraulic engine is always softer working, the largest factor of the stop occurs with the existence of the feed rate, which is approaching zero. If a strong billet falls into the hydraulic unit supply, it will be pushed into a column in non-stop mode, which can lead to damage. For rover woodcut (based on all the above comments), you need a more powerful engine. To calculate its power, you can simply shift the efforts of the split, which exists for hydraulic drive: a pokka with a diameter of 20 cm – 2.6 TC, the efficiency will be about 0.87.
Often interferes with the movement of the workpiece too thick cakes. As an output you can see: the rack units are appropriate when the amount of work is relatively small, work is done using muscle strength.
For small workpieces of firewood, it may well be a vertical screw rover. This device has a small performance, it is not afraid of various flaws of wood blanks. The electrical engine for its operation can fit the low-power, only 2.8 kW – from the washing machine, with the drive on the pulley. With a small power engine, such an unit will be able to “cope” with elements up to 42 cm in diameter with a height of up to 65 cm. To create it, the engine will be required from a washing machine, the speed of rotation of such a power plant may well come up. The disadvantage may be that by mounting the column directly to the engine shaft, the engine body can be a story, and it will break.
In the work, the main role is given to the nozzle in the form of a cone, which has a thread and rotates at a speed of 160-1550 revolutions per minute (operating frequency is usually 300 revolutions per minute). The carving is made left due to the fact that people in their mass are right-handers, their right hand is physically better developed.
The billet on the screw column comes on it along the vertical plane. During the movement, the preparation (her movement) is correct. Such a question is not the best way to affect the safety level, therefore it is necessary to take into account the fact that the screw rover is a hazard. From the employee is required to monitor constantly so that under the right hand too little material remains. If the column is stuck, the process of winding the workpiece will happen. So that such incidents do not occur, it is necessary to mount the crusher under Kisna.
The rationality of the design may affect the assembly and operation of the screw unit, as well as the location of such nodes:
- Wedge stop;
- Drive pulley;
- The work of the main tree.
And also important, what form of the column itself, as it is sharpened, such parameters will certainly affect the work of the aggregate itself. Wedge is also important, it determines the safety of the unit and affects productivity and reliability. If the stop is incorrect, then problems will arise with the engine, the functioning will occur with a large voltage of the power unit. Performance will be noticeable below. It is impossible to leave a column on weight without the presence of the lower stop. Wedge emphasis is attached to the bottom. At the same time, its length may be such that the nose was longer than 1/4-1 / 2 thread distances.
The stop parameter corresponds to the diameter of the kolun in a similar section (is taken away with 4 height of the threaded part). The distance between the shank and the focus is about 1.8 mm, however, if the gap is 0.8 mm, it will even be better. Colong will first “disturb” a little, but after a short time a trigger will occur, the product will serve quite a long time.
Vertical emphasis is 2/3 shanks. For 76 mm limits are limited to 52-62 mm. Tightening the workpiece has to be intercepting manually after the colon is quite deeply entering the tree. If the column has entered too deep into the material, it will be impossible to keep it with bare hands. Tighted lower part knocks on the side of the stop. In this case, damage and defects are possible.
It is necessary to make the unit so that the clip and the main shaft drive is made according to the instructions, in this case nothing will happen and there will be no damage. In the screw rover, the inertial pulse on rotation is carried out by transmission through the pulley. The pulley should slip if “Zahuk” happens, otherwise the accident is inevitable.
In this regard, the transfer with the help of a circuit is more rational and practical, “zaetkov” becomes noticeably less. The chain itself has a lot of weight, because the transmission is tougher and allows you to overcome the “obstacles”. If the blanks have too many bitch, it will be necessary to install a drive, which is represented as a powerful drive pulley.
There is a carrot screw, this unit, really, resembles the root. The unit is simple in the device and assembly, it is possible to work with it when it is a blank of a small amount of firewood. And also this device can cut the tree, so the ring of the screw provides a sufficient amount of sawdust. In the farm it is sometimes claimed if there is a poultry house, which should be missed.
Woodwood with sliding kolun – another option. Shoulder is taken into account 1.6 meters. Overload can be up to 40 kg. In case the wood cutter is stationary, then in this case it can work as an inertial lever, that is, it can be raised by the handle, and then with the effort to lower it to the workpiece. If the colon is dynamic, then it can be easily moved along the lever, in this case it can be push. The shoulder is significantly lengthened. In the lever rover there are a number of features:
- It is best to use the Kolong “Arrow”, to buy it is easy;
- The lever holds on the spring in a horizontal position;
- the spring must be fastened well so that it does not fly;
- Often the spring is passed into a moving pendulum guide.
If the mechanical unit is not attached to the base, then it is made with a diameter that is not inferior to the size of the lever shoulder (the size of the wooden blank is 5 times the size). It makes no sense to create “mechanics” with a fastened kolun, which slides on the guide. Even if the columan beat with all the power of a sledgehammer, then he will often jerk.
Often also use cone-shaped woodcut, which in conditions of private household (when firewood must be relatively few) can cope with rather sweaty baccasters (up to 55 cm in diameter). The cone is made in size 82-148 mm, the angle of inclination is about 16 degrees, if the tree has small layers, and 19 degrees, if the layers are straight. The angle of a solution of 26-32 degrees changes to a third of the height of the cone. Best use the rush jack. Rack jack is preferable because it is very simple and reliable, not afraid of large loads. With hydraulic device more work, and it is more vulnerable at excessive loads.
Another detail is important. The rod of regulation of the conical colon makes usually functioning, use the reinforcement or rod steel brand ST47, the diameter at the same time at least 22 mm. The carving is made in the form of a trapezium (often the sewage valves are suitable, where the steering wheel is removed and replaced by the lever).
You can also make your own wood cutter in the form of a saber, such a device is also called a saber. Lever shoulder here at least 0.9 meters, made from soft wood (pine, birch). It is possible to work with such a woodcutter with soft trees. And also on dachas put on the winter woodcases of the lever principle of action, which can break the blanks up to 35 cm in diameter. The productivity of such an aggregate is low, but in order to pull firewood for dinner, quite such a device enough. With the help of the pedal, the shifting stop rises, then it is released and put on the pedal, so the billet is separated.
Make a woodcutter can be even made of wheels, we will look at the technology below.
Woodcut can be made from a jack, which is manually given by physical force.
Such materials will be required:
- hydraulic jack;
- steel sheet 5 mm;
- Schweller or corner number 8;
- Bolts and nuts.
List of tools:
- welding machine;
- triangle ruler;
It is important to correctly fasten the vertical mounts, the lion’s share of load will be laid on them. It will be necessary for these purposes. Corner number 8 or foreign corner. Then the wedge is made, which rubs wooden blanks. This element is made of steel or corner. And the wedge is recommended to sharpen well, then the work will be more productive. The jack will be put by a velocus with the lower rack that you need to lift a little over the base. To do this, you need to fight a few flat sheet steel trimming. Jack must be well fixed so that it does not jump in the process. The element is additionally attached to the choms with nuts.
We will also need springs that will return the element to its original state. It should also be done a reliable bird that is best to cook from steel. So that the reference base is fixed firmly on the jack, the round tube is welded to it. And also need to fight fastenings for springs. Put the device mainly in the angle, it can be additionally “grab” bolts to two walls.
From a wheeled disk
Woodcut can be made from a tractor wheel disk or cargo machine. In the cavity of such an element, you can pour concrete to increase the mass. A vertical fastening similar to the guillotine is welded to the central block. The disk rotates, and the “guillotine” falls and beats on the spot, which is attached in the center. Work on such a unit is not easy, you need practical experience.
During work, security measures should be followed. Energy that is spent on splitting of wood elements, quite significant. Split rotation speed can be high. Before running the drive, check all fixing elements:
- bolt connections;
- Mounting pulley;
- Machine Machine;
- Knives must be necessarily in good condition, without chipping and signs of corrosion.
Clothes with long sleeves should be free and thick fabric should also be:
- good working boots;
Technique should be located on a flat stable surface, which is “not afraid of” powerful vibration. Reinforced concrete stove – an ideal base for the basing of such an aggregate. On the machine you can process parts only such that correspond to the equipment format. And a few more tips:
- When the machine is running closer than three meters, it is not recommended to approach it;
- The working area should always be fired by a paper tape from paper or PVC material;
- The technique should work only under the supervision of the employee;
- When working should be carefully monitored so that foreign objects do not fall into the unit;
- Preventive inspection and test starts should be carried out regularly;
- All equipment for the repair of equipment is carried out with a disconnected engine.
Useful to change drive belts. The old pulley “remembers” the trajectory of movement, over time it becomes tough, which provokes an excess vibration.
