Such a source of heat like wood (firewood) is known to humanity from ancient times, and although gas heating, firewood is almost universally used, and to this day remain relevant and in demand for a large number of population. However, the harvesting of firewood for the winter as a source of heat is a labor-intensive matter, because you need not only to deliver wood, but also to recycle it. Human thought over time improved this process – folk craftsmen have come up with such a comfortable device as a mechanical wood cutter.
Design and principle of work
Firewood will not lose their relevance for a long time, remaining convenient, economical and eco-friendly fuel. There are several reasons for this:
- In the outback in many houses and to this day there is no alternative to chimney heating;
- Saunas, Baths, offering their customer attraction services, almost always indicate that it is used to obtain heat to heat, and environmentally friendly and certain breeds;
- No picnic will cost without an old good fire – both for cooking and to create heat and a cozy atmosphere.
Initially, various types of handcolun and wedges were used to facilitate the rolling rods of firewl. But in the process of operation, such primitive adaptations have proven themselves as ineffective, because they were traumatic, and often they were simply stuck in the lounge. Therefore, they came to shifts. This simple mechanism saves not only strength, but also a large amount of time. But the folk craftsmen did not stop at this, deciding to minimize the strength and time on the process of workpiece of firewood, improving wood cutting technology. So there were mechanical wood firings.
This idea was picked up numerous industrial enterprises, but there are such mechanisms for weeks, therefore the answer to the question – how to make a mechanical woodwood with their own hands – it remains very relevant.
Depending on the design type, the woodwave consists of the simplest arm support for increasing the effort used or a number of side mechanisms that serve to facilitate the process of harvesting. To side mechanisms are the shoulder to which the column is attached, and the frame – the bed, on which the colon is held. In general, a complex of such simplest devices forms a mechanism capable of facilitating the work on the harvesting of firewood.
Pros and cons of homemade models
Consider several of the most successful models of mechanical firewood, which are easy to manufacture, are easy to use, safe and able to simplify the process of processing wood in firewood. Mechanical woodwaves are divided into several types. Consider their positive parties and disadvantages.
A simple version of self-made firing with the simplest drive, to make which is the easiest way, since it does not require much cash costs. Even in the case when it is not necessary for the necessary parts, their acquisition will not be special. However, such a device will bring the greatest benefit only with the minimum need for firewood. The minuses of such a woodcut are the long handle on which the cutter is attached, and considerable efforts. But even such a primitive mechanical wood cutter is capable of noticeably ease of work on the preparation of firewood.
Spring clamping carving
The clamping or spring woodcut involves certain costs for manufacturing materials, but will significantly reduce the burden on the muscles of the employee. Mechanics remains the same, but the rope is added to the spring shelf. Spring should not be deformed when compressed and have a certain elasticity (rice. 2). The height of the bed of such woodcover is usually 65-80 cm. The design of a simple, takes a little space, but has its drawbacks:
- Such wood cutting requires comprehensive work with a shock tool, which increases the risk of injury;
- It makes much easier, but does not reduce efforts when harvesting firewood to a minimum.
Vertical inertial woodcut
Another simple variant of mechanical woodcutter. The advantages of such a woodcutter serve simplicity of manufacturing and low cost. And also this woodwave will make it easier to work with soft wood rocks. There are few minuses of such a wood – it is useless to work with viscous species of wood, as the column will be knit in the linen and get it, given the small size of the wood cutter, will be problematic.
In order to make it easier to make it easier in the process of turning wood into solid fuel by applying mechanical wood cutting, it is possible to install an electrical drive on it, as shown in the photo (rice. 4). However, the manufacture of such woodcaps requires certain costs, knowledge in the electromechanics, the ability to read the drawings and the use of electric welding.
Tools and materials
To make a hand-cutting machine, you will need:
- metallic profile;
- Ax or Colunde.
For the manufacture of vertically inertial woodcolting, you will need:
- two metal pipes of different diameters;
- weighty piece of metal in the form of a plate for base;
- Directly executive tool – cutter.
In order to assemble the most effective view – electromechanical woodwood – at home, you will need to make a cone. It is made of cylinder ST-45. Length – 14.5 cm, diameter – 55 mm. 30 degree inclination angle. Then, on the turning machine on the resulting part, a carving of a depth of 2 mm is applied (step 7 mm). The manufacturer is put on the motor shaft or gear axis and pinned with a pin. On the other hand, the shaft on the axis is attached to the bearing, and the star is fixed for the chain or the pulley for the belt. Cone is located at an altitude of 10-15 cm from the surface of the frame-bed.
Materials for manufacture:
- Cylinder ST – 45;
- electric motor;
- Metal for assembling bed;
- belts or chain;
- starting device;
- Plonic steel for the manufacture of protective housings.
Pros – minimum effort in the process of the workpiece. Cons – collect such woodwood home will be expensive. It is necessary to spend not only for the purchase of necessary materials, but also on the services of Tokarei, electric zone and welders.
How to do?
The easiest way to do the mechanized woodcut (scheme 1). The assembly is very simple: the cutting portion is fixed on a vertical rod with a sole of any profiled metal, but leaving the possibility of free movement of the rod. Motion assembly may consist of two welded ears with holes on a rack and a metal retainer-finger serving the shaft for the rotation of the fastening and a colon.
Clamping or spring woodcrew will require a little big effort in the manufacture. Between the bed and horizontal movable shoulder with a cutter, the shelf is welded to which the spring is installed and fastened, the second end of the spring is attached to the horizontal shoulder of the firing, shocking the cuts on the cutter (Kolun). When taking into account the fact that the executive part of the firing is weighting, then the blow to the split deck is made with a minimum of effort (rice. 2). However, still some efforts are necessary, since the return will appear due to the spring. At this point, the attention should be paid to the spring used in the device so that the column should be effective when hitting, it could safely prick wood, and at the same time the design shoulder it would be easier to keep the.
Collect vertically inertial woodcut is very simple. First you need to weld the first pipe to the base plate. Length of such a pipe is a little more than a meter (rice. 3). Then from the tube of the larger diameter it is necessary to cut off a piece that will be larger than the length of the kolun. Then it is necessary to weld the column to a piece of tube of a larger diameter and put on the bottom tube. The principle of operation is extremely simple – installed on the base under the column and beaten from above another full-pitched or sledge hammer.
Electromechanical woodcut will require the cost of the engine itself, metal for the manufacture of frame, gearbox, cone (executive part), components and consumables. The drawing of the executive part (cone) is shown below (rice. five).
The engine is installed on the frame, it is connected to the gearbox, which transmits movement to the cone directly or by belt transmission. In order to power such an electric motor, certain skills will be required, as special parameters and engine requirements are taken into account. The engine power should not be less than 2 kW, and the number of revolutions, as a rule, from 250 to 500. Such an engine can be connected directly to the cone.
Not trouble if you find a passing engine failed. In this case, you need to purchase a gearbox – an increase in or lowering the number of revolutions depending on the number of engine speed. Consequently, the engine with the number of revolutions from 250 to 500 can be installed directly with the cone, and the engine using the gearbox is better located at the bottom of the frame and transfer the movement of belts.
When working with mechanical devices of any type, there is always a risk of injury. When using homemade woodcuts, this risk is often not reduced, but increases. Always and under any conditions do not forget about safety technician. When using mechanical woodcuts:
- In order to maximally protect yourself from all sorts of injuries, falling out of sawdust or pinch into the eyes, you need to work in protective clothing, shoes, glasses and a protective helmet;
- Wood, activated in recycling, should be firmly installed and fixed in chutes or special recesses;
- It is not necessary to work in poor visibility conditions or on a slippery surface;
- All elements of mechanical woodcuts should be firmly welded and fixed together;
- Colong or cutter should not have chips and cracks;
- should not be engaged in the workpiece in the immediate vicinity of other people;
- It is important to closely monitor the state of the tool used.
When using electrical drive mechanisms, the electric part should be paid primarily as well as:
- The wiring must correspond to the desired cable cross section and do not warm up while using the tool;
- All parts used are sockets, electric forks, launchers – should not have visible damage and be powered into an electrical network according to the standard;
- All moving elements of the mechanism must be fenced with a protective casing and lattice to avoid working clothing, hair and other things in them;
- Workwear should be dense, be paid, holistic and not having savings;
- When using a belt, the free residue is best to fill;
- glasses and gloves must be holistic, glasses should have a good overview.
Woodcuts have become indispensable assistants when harvesting a large amount of firewood. They will save the time and strength of a person many times, and do not require the cost of significant funds with their own manufacturer in contrast to factory samples. But do not forget that in reasonable volumes, physical work enlisters and raises the will of man. Therefore, sometimes more pleasant and more useful to perform a small part of the workpiece of firewood with a conventional ax.
