Abstract

The invention relates to the mechanization of forestry production and allows to improve the quality and reduce the energy intensity of the tillage process. The gun contains a four-link hinge mechanism mounted on the front of the base machine with the bottom 2 and top 3 frames and the floor of the rack 4 and the working body (PO) 6 with the hydraulic cylinder 8 of the burial. PO with one hinge 5 is connected to the stand 4, and the other 7 to the upper frame 3 by means of a hydraulic cylinder 8. At the same time, the hinges 10 and 11 of fastening the upper and lower frames to the rack 4 are located between the hinges 5 and 9 of the cannon to the rack 4 and the upper Box 3. RO is lowered to the ground. With the aid of the hydraulic cylinder 8, the required depth value is established. If it is necessary to remove obstacles that are not overcome by the pushing force of the machine 1, the rod of the hydraulic cylinder 8 is advanced and the PO is deepened by the obstacle. The rod moves back. The PO rises, the obstruction is removed. 7 § / il. (L s: yu // /// Phi.1

Description

The invention relates to the mechanization of forestry production, in particular, to front linkage devices with equipment for the preparation of strips on the cuttings.

The purpose of the invention is to improve the quality and reduce the energy intensity of the process of tillage on flat cuttings.

FIG. 1 shows a tool for clearing and preparing the soil in the cuttings, general view; in fig. 2 - the same plan view; in fig. 3 and 4 is a diagram of removing obstacles (mon) from the treated band; in fig. 5 - 7 - schemes of automatic control of the stability of the working body stroke.

the fallen dead dog, etc.) the front part of the tractor frame rises, while the elevation radius of the upper frame RI connection point is greater than the radius of the lower frame connection point Rg, and the upper frame 2 is less than the length of the lower frame 2, therefore the pillar 4 turns clockwise around the hinge 5, and the hinge 9 connecting the hydraulic cylinder 8 to the frame 3 rotates around the hinge 10 counterclockwise, leaving the reference plane of the working body 6 in a horizontal position. When lowering the front of the tractor, such as moving over a deep track, the stand 4 turns against the chisel for clearing and preparing the postal needle, and the hinge 9 is clockwise on the arms, mounted on the front of the tractor 1, contains the bottom 2 and the top 3 frames of the hinged system to which the rack 4 is connected, connected at the lower point by the hinge 5 to the working body 6. The working body 6 of the gun is connected by the hinge 7 located in the front part of the working body to the hydraulic cylinder 8 of the burial, which is the second end connected to the upper frame 3 by the hinge 9 and the widening

the upper frame 3 with the stand 4, while the hinge 11 connecting the lower frame 2 with the stand 4 is located above the hinge 5.

The tool works as follows.

The working body 6 is lowered onto the ground and with the help of the hydraulic cylinder 8, the amount of its penetration is established. If it is necessary to remove obstacles that are not overcome due to the tractor pushing force (large stumps, stones), the hydraulic cylinder rod 8 is pushed and the working body 6 is buried under the obstacle, 35 after which the hydraulic cylinder rod moves in the opposite direction, the working body rises, digs an obstacle, with the possibility of splitting from the bottom along the fibers, when it is uprooting Mon, and when it is dredged and cut, and the roots are broken, the soil is broken.

After the obstacle is deepened, the working body is set to the necessary amount of deepening and upon further movement of the aggregate, the obstacle is removed for

The ke and the supporting surface of the working member b remain horizontal.

The proposed technical solution makes it possible to ensure a steady course of the working body of the frontal linkage in depth and to remove obstacles (stumps, stones, etc.). In addition, the tool provides continuity of movement of the unit (without reciprocating movements), which allows its use as part of a complex

one pass, i.e., the application of new technology for the creation of forest crops — clearing lanes while simultaneously preparing the soil and sowing or planting the seedlings with a rear linkage machine.

The use of guns in a complex unit increases productivity by 2-3 times in comparison with performing these operations separately.

Invention Formula A tool for clearing and preparing soil for cuttings, including a base machine, on the front of which there is a mounted four-link gearbox with a carrying stand, upper and lower frames, a working body and a hydraulic cylinder for the burial of the latter, characterized in that, in order to improve the quality and reduce the energy intensity of the process tillage on flat cuttings, the working limits of the strip to be calculated for a width of 45 gan are connected by a single joint with a stand. seizure of a worker organ. When moving on a flat surface, the working body 6 with the reference plane copies the soil surface in a longitudinal-vertical plane. When a tractor hits an obstacle (stump, torn stone, and others — with the upper frame through the buoyancy cylinder, the hinges for fastening the upper and lower frames to the rack are located between the joints of the working body to the rack and the upper frame. the fallen dead dog, etc.) the front part of the tractor frame rises, while the elevation radius of the upper frame RI connection point is greater than the radius of the lower frame connection point Rg, and the upper frame 2 is less than the length of the lower frame 2, therefore the pillar 4 turns clockwise around the hinge 5, and the hinge 9 connecting the hydraulic cylinder 8 to the frame 3 rotates around the hinge 10 counterclockwise, leaving the reference plane of the working body 6 in a horizontal position. When lowering the front part of the tractor, for example moving over a deep track, the post 4 turns counterclockwise, and the hinge 9 clockwise, and the supporting surface of the working body b remains horizontal. The proposed technical solution makes it possible to ensure a steady course of the working body of the front linkage in depth and the removal of obstacles (stumps, stones, etc.).
