When felling and pruning trees, logging residues always remain. Whether it's sanitary cuttings or single removals, whether it's a site clearing felling or pruning of dry branches. There will always be wood waste. There is different ways disposal of this type of waste.
1 Burning on site.
Fast enough and not expensive, but it is not always and everywhere allowed from the legislative side and not always possible due to the increased fire hazard.
2 Export and disposal.
Fast but costly. Bins of MSW (Household Solid Waste) are ordered with sizes from 8 to 27 cubic meters. Logging residues are loaded into them manually or mechanically and taken to the landfill for disposal. Everything is legal and always allowed.
3 Grinding logging residues into chips.
Fast, economical and completely legal. With the help of a chipper, the sawn wood is converted into technological chips with a fraction of 2-5 cm. Which can be used for garden purposes or left at the felling site, it will turn into fertilizer for the next season. Also, wood chips can be taken out by a bunker to the landfill, if it is absolutely not needed. This is much more profitable than transporting uncut wood. Since, in unground form, wood residues take up 6-10 times more space (depending on the plant species) than wood chips.
When it comes to the removal of 1-5 small trees, there is not much difference in money, but when the volume of felling is more than 10 trunks, the difference becomes very noticeable. And when exporting 100 or more units, it is colossal.
Let's show it clearly:
Let's say you have 4 trees that need to be removed.
The cost of supply and export of 1 bunker for 27 cubic meters is about 10,000 rubles. Manual loading of the bunker is about 5500 rubles. About 4-5 trees with a diameter of 30 cm are placed in one such bunker.
Means: loading + removal + disposal of 4-5 trees will cost 15,500 rubles.
Now let's imagine that you have 22 trees that need to be removed. Diameter too, up to 30 cm.
If we use the previous scheme, we get that we need 5 bunkers with loading, which is 15.500 * 5 = 77.500 rubles. The amount is not small. Let's see how this amount changes if you use a grinder.
Calling a chopper - 18,000 rubles (7 hour shift). Calling a bunker - 10,000 rubles (most likely everything will fit in 1, it all depends on the type of trees, you may have to call another small bunker, for 8 cubes, the price is about 4,000 rubles). You will also need movers. For a day. 3 people - 9000 rubles. The result is 18.000 + 10.000 + 9000 = 37.000 rubles (41.000 if you need to call a small bunker). The benefit is obvious. Almost 2 times.
Well, if you have more than a hundred trees, then it is considered individually. Since such volumes are usually loaded mechanized. With a large number of ordered bunkers, scavengers give discounts. But still, using a shredder will save from 50 to 70% of the export budget.

The invention relates to forestry, in particular to equipment for cutting logging residues.
According to a / s No. 979114, B27L 11/00, published 12/07/1982, a mobile chipper is known, containing a self-propelled chassis on which a chopper is installed, a hydraulic manipulator with a gripper, a fan, a chopper drive. The shredder includes a multi-cutting drum, a body with a loading cartridge, rotary device, consisting of a drive shaft, a belt drive. On the drive shaft mounted levers that move along the lever and fixed on it in a certain position. The operation of the mobile chipper installation is carried out as follows. Using a hydraulic manipulator, large-sized wood is fed into a loading cartridge to a multi-cutter drum, which is used to grind wood. To grind the wood, a rotary device comes into operation, which rotates the wood with the help of a drive shaft and levers at a certain angle. Rotating the drive shaft in the opposite direction, the wood is pressed against the multi-cutter drum with the help of levers. The resulting chips are conveyed by the fan through the chip line to the chip truck.
According to patent No. 2354545, C1 B27L 11/00, published 05/10/2009, (prototype) a device for grinding logging residues is known. It works as follows: by maneuvering the tractor, the device is fed to a pile of logging residues, so that the frame of the lifting device is located in the lower part of the pile of logging residues, with the help of a hydraulic cylinder, the lifting device places the logging residues at the level of the larger equipment of the loading cartridge body. Rotating cutting discs allow cutting residues entering the loading cartridge body to the required overall dimensions, while the finger-type feeder, feed mechanism and feed rollers ensure a constant supply of branches to the loading cartridge body and further movement to the chopper. The crushed parts of crowns and branches are transported through the chip pipeline under the action of centrifugal force.
The disadvantage of this device is that due to the low performance of the finger-type feeder, the absence of gripping teeth on the feed rollers and the synchronizer on the pulleys, the productivity and quality of work on cutting logging residues are significantly reduced.
The technical objective of this invention is to improve the performance and quality of the device for grinding logging residues.
The technical problem is solved in a device for crushing logging residues, containing a prism-shaped loading cartridge body, a wood chipper, a grinder, a belt drive, a drive shaft, a feed mechanism, a lifting device frame, a hydraulic cylinder, a pipeline, an oil tank, cutting discs, a console, a system of pulleys with shafts , V-belt transmission, reduction gear, characterized in that the feed mechanism consists of a star-type feeder, the axis of which is installed at the base of the lower part of the inlet of the loading cartridge, the feed rollers are equipped with gripping teeth perpendicularly attached to the inner side walls of the loading cartridge body in two rows , and on the outer side of the side walls of the body of the loading cartridge on the axis of the feeder of the star-shaped type there is a synchronizer that provides synchronous rotational movement of the nodes that make up the feed mechanism.
The difference between the present invention and the prototype is that the feed mechanism consists of a star-shaped feeder, the axis of which is installed at the base of the lower part of the feed cartridge inlet, and feed rollers equipped with gripping teeth perpendicularly attached to the inner side walls of the feed cartridge housing in two row, on the outer side of the side wall of the loading cartridge body, on the axis of the star-shaped feeder, there is a synchronizer that provides synchronous rotational movement of the units that make up the feed mechanism.
The figure 1 shows a side view of the device for crushing logging residues, figure 2 shows a top view of the device for crushing logging residues.
SUBSTANCE: device for chopping chopping residues contains a body of a loading cartridge 1, a chipper 2, a chipper 3, a belt drive 4, a drive shaft 5, a feed mechanism 6, consisting of a star-type feeder, feed rollers 7 equipped with gripping teeth, a lifting device frame 8, a hydraulic cylinder 9, pipeline 10, oil tank 11, cutting discs 12, console 13, pulley system consisting of pulleys 14, pulley 15, pulley 16, shaft 17, shaft 18, V-belt transmission 19, reduction gear 20 and synchronizer 21.
The device for crushing cutting residues works as follows: by maneuvering the tractor, the device is fed to a pile of cutting residues in such a way that the frame of the lifting device 8, hinged on the outer side of the side walls of the housing of the loading cartridge 1 on the axis of the feeder of the star-shaped type of the feed mechanism 6, is located at the bottom parts of a heap of logging residues. After that, excess pressure is created in the hydraulic cylinder 9 using the pipeline 10 and the oil tank 11 connected to the tractor hydraulic system. As a result, the rod of the hydraulic cylinder 9, leaving the body of the hydraulic cylinder 9, acts on the frame of the lifting device 8. Since the frame of the lifting device 8 is a multi-link system, the horizontal movement of the rod of the hydraulic cylinder 9 is converted into the vertical movement of the frame of the lifting device 8. As a result, a bunch of logging residues is located at the level of the larger base of the body of the loading cartridge 1, which has a prism-shaped shape, the smaller base is attached to the grinder 3, and the larger base is the inlet for supplying cutting residues.
Rotating cutting discs 12, which are rigidly mounted by means of a console 13 on the axis of the feeder of the star-shaped type of the feed mechanism 6, located on the sides of the inlet window of the loading cartridge body 1, make it possible to give the desired overall dimensions to the chopping residues entering the loading cartridge body 1. At the same time, the star-shaped feeder of the feed mechanism 6, the axis of which is installed at the base of the lower part of the inlet of the loading cartridge body 1, and the feed rollers 7, equipped with gripping teeth perpendicularly attached to the inner side walls of the loading cartridge body 1 in two rows, provide a constant feed branches into the body of the loading cartridge 1 and further movement of the cutting residues to the chopper 3. Synchronous rotational movement of the star-shaped feeder of the feed mechanism 6 and the feed rollers 7 equipped with gripping teeth, and, accordingly, the linear movement of the crushed material in the body of the loading cartridge 1 at a certain speed feed is provided using a belt drive 4 and a pulley system consisting of pulleys 14 with a synchronizer 21, a pulley 15, a pulley 16, which are connected to the power take-off shaft of the tractor through a reduction gear 20 with shafts 17, 18 of the drive shaft 5 and a V-belt drive 19 . The shape of the body of the loading cartridge 1 and the feed rollers 7 located in it contribute to the compaction of the mass of cutting residues for grinding. Crushing of logging residues occurs with the help of cutting elements located on the front part of the grinder 3. The crushed parts of crowns and branches under the action of centrifugal force are transported through the chip line 2 to the receiving container or remain in the clearing for rotting.
The continuity of the supply of material for grinding is ensured by moving the machine-tractor unit along the cutting in a low gear.

How is the chopping of logging residues and branches
Chippers are focused on grinding and crushing wooden boards, plywood, chipboard into chips and sawdust.
In some cases, in the production of furniture or wood blanks, up to 15% accumulates in waste source material. It is practically impossible to transport unprocessed waste with a specific weight of less than 200 kg/m3 cubic meters in European countries. To increase the ergonomics of transport, the waste is always shredded. Wood chips are used to kindle boilers, to cover enclosures for keeping pets and livestock, to create chipboard and other furniture materials. Wood chips are also supplied to private farms (to cover fields for fallow winter quarters, to protect plant rhizomes from frost, etc.).
