Description

The invention relates to agricultural land reclamation and can be used for clearing land from small tree residues in the production of cultural and technical works.

The aim of the invention is the expansion of technological operations.

FIG. 1 shows the layout of the device in the working position; in fig. 2 - trawl between the load and the nearest depth limiter; in fig. 3 - attachment of the tooth to the lower string; in fig. 4 is a diagram of the vertical hinge at the leading tractor.

A device for harvesting wood residues includes a leading 1 and driven 2 tractors, a trawl consisting of a pair of sidewalls 3, which have a lower string of a pair of cables 4 and an upper string of a cable 5, a vertical hinge 6 connecting the side of the trawl to the driven tractor. The device also contains a vertical hinge 7 connecting the other side of the trawl with a leading tractor and equipped with a probe 8, the sleeve of which is mounted on the hinge axis and has a latch 9, a pair of spring-loaded pushers 10, a pair of microswitches 11, a light-signaling device 12 and a circular scale 13 , fork teeth 14 with a cylindrical hinge 15 and cable slots 16 attached to the lower string. In addition, the device includes a cargo 17, dividing the trawl into two sides, depth-limiters 18, dividing the sides of the trawl, vertical posts 19, connecting teeth with the upper string, vertical cable segments 20, connecting the tooth with the upper string, inclined cable segments 21 connecting the teeth to the upper string, and horizontal rods 22, fastened to the axis of the vertical hinges and connected to the upper and lower bowstrings.

The device works as follows.

Initially, the trawl is tuned to a maximum angle between its sidewalls, which determines the width of the trawl and the distance between the tractors and the teeth of the trawl. For this, the rods 22, fastened to the axis of the hinge 7 and connected to the upper and lower string, are moved relative to the circular scale 13, with

This rotates the hinge axis and is set to the desired position marked on the round scale. Then, the probe 8 is fixed in this position with a latch 9. Then the leading 1 and driven 2 tractors pull the sidewalls 3, and the load 17 forms an angle between the sidewalls due to the force of the load on the soil directed opposite to the movement of the tractors. When moving, if the distance between the tractors differs from the specified path, the probe rests on one of the spring-loaded pushers 10, which then interacts with one of the microswitches 11, which will turn on the device 12 light signaling. According to the information of the device 12, the driver of the leading tractor reduces or increases the distance between the tractors by approaching or moving away from it. At the maximum initial angle between the sides, the distance between the teeth 14 is greatest and the tooth 14, combing the surface of the soil with its pointed ends, collect the largest woody residues that accumulate in the corner between the sidewalls in the form of a heap. With further collection of wood residues, they displace even previously collected wood residues along the vertical segments 20 and uprights 19. The upwardly displaced wood residues roll down in the direction of movement of the trawl, forming an angle of repose of the pile between the trawl sides. When the load crosses the 17th floor, the tractors stop, the latch 9 disconnects the feeler 8 from the axis of the hinge 7 and the tractors start moving in the opposite direction.

The use of the proposed device will improve the productivity of land clearing of small wood residues due to the fact that the width of the trawl is significantly greater than the width of the known devices, and to combine all technological operations into one continuous process of harvesting tree residues while preserving soil fertility. In addition, the use of the device will allow to reduce the material consumption of the technological process due to the fact that the trawl of cables is less material-intensive than the equipment of used land reclamation machines.
