Description

The device belongs to the forestry industry and is used as a means for clearing linear objects, such as power lines, communication lines, oil and gas pipelines from trees and shrubs and creating artificial fire barriers in the form of mineralized strips along these linear objects or around settlements .

A device [1] is known, including a frame with upper and lower transverse beams hinged on a self-propelled chassis, T-brackets on which cutting bodies with actuators are mounted, fixed hinges with which T-brackets are mounted on the upper transverse beam of the frame . Between the upper transverse beam and the lower transverse beam, a transverse inclined baffle wall and longitudinal side walls are rigidly attached, forming a working hopper for chopping cut tree-shrub vegetation.

However, the insufficient rigidity of the fastening of the cutting organs inside the frame structure and the lack of the ability to control the position of the cutting bodies inside the frame structure do not allow the use of this device to create artificial fire barriers along linear objects.

Also known is a mulching device [2], including a self-propelled chassis, a front mounted grinding working element in the form of a rotating drum with cutting elements and a bending-supporting device.

The need to install this mulching device on energy-saturated tractor bases increases the energy consumption for clearing cultivated areas and creating artificial fire barriers.

The closest of the analogues is the device [3], which is taken as a prototype. This device includes a frame structure mounted on a self-propelled chassis by means of a hitch, made in the form of a hopper, consisting of upper and lower transverse beams, a rear inclined wall, longitudinal side walls and an upper hinged lid, cutting bodies with drives fixed with T-shaped brackets and adjustable traction, providing additional rigidity to the fastening of the cutting organs, as well as a bending device located above the cutting organs.

The disadvantage of the prototype is the inability to control the position of the cutting organs relative to the frame structure in the form of a hopper from the tractor operator’s cabin without stopping the operation of this device.

The technical result achieved by the proposed device is the expansion of technological capabilities and operating efficiency of the machine for clearing linear objects from wood and shrubbery.

A technical result is achieved due to the fact that each T-shaped bracket with a hinge is connected to another hinge mounted on the rear wall of the frame structure using a hydraulic cylinder to regulate the position of the cutting organs from the cab during operation.

In FIG. 1 shows a machine for clearing linear objects from tree-shrubby vegetation in a section. A machine for clearing linear objects from trees and shrubs includes a frame structure 2 mounted on a self-propelled chassis 1 with walls forming a working hopper for cutting and shredding trees and shrubs. Cross beams 3 and 4 form the frame of the rear wall 5 with its inclination to the horizontal. With the transverse beams 3 and 4, the longitudinal side walls 6 of the frame structure are rigidly connected. The top hopper is closed by a hinged lid 7.

Inside the hopper are placed the cutting bodies 8 with cutting knives 9. The cutting bodies are mounted together with the drives on the mounting transverse beam 10. The mounting beam 10 is removable and fixed between the longitudinal side walls 6 parallel to the transverse beams 3 and 4. For mounting the cutting bodies with the drives, T -shaped brackets 11. On the vertical shelf of the T-shaped bracket 11, the bearing assembly of the cutting body with the shaft 12 and the coupling 13 is mounted. On the horizontal shelf of the T-shaped bracket 11, the drive motor 14 and the fixed hinged joint 15, with the help of which the cutting body is fixed on the mounting beam 10.

A hinge 16 is installed on the vertical shelf of the T-shaped bracket 11, with the help of which the T-shaped bracket 11 is additionally attached to the frame structure 2 by means of a hydraulic cylinder 17 and another hinge 18 mounted on the rear wall.

Above the cutting bodies 8, a bending device 19 is installed, the posts 20 and 21 of which are supported by a frame structure. On the rear wall of the frame structure 2, brackets 22, 23 and a hinge 24 are mounted for hanging on a self-propelled chassis 1. Each cutting body 8 has a lower protective disk 25.

A machine for clearing linear objects from trees and shrubs works as follows. When the drive motors 14 are turned on, the cutting bodies 8 with the cutting knives 9 receive rotation. When pushing the self-propelled chassis 1, the trunks of woody-shrubby vegetation are pulled by a bending device 19, cut off with knives 9 and pre-crushed with the same knives.

The mounting beam 10, on which the cutting bodies 8 are mounted using T-shaped brackets 11 and fixed hinges 15, serves as an additional transverse connection and enhances the rigidity of the frame structure. The presence on the vertical shelf of the T-bracket 11 of the hinge 16, connected to another hinge 18, mounted on the frame structure 2, by means of the hydraulic cylinder 17 allows the tractor operator to adjust the position of the cutting body in the hopper during operation directly from the cab. A machine for clearing linear objects from trees and shrubs can also, by changing the position of the cutting organs, reduce the height of the stumps or chop the fallen tree trunks, while cutting the knives into the soil, cut the roots and create fire strips.
