RU163148U1 - WORKING BODY OF THE MACHINE FOR CUTTING OF WOOD-SHRUBBLE VEGETATION AND LAYING OF MINERALIZED STRIPES - Google Patents

Abstract

The working body of the machine for cutting wood and shrubby vegetation and laying mineralized strips, including a rotating drum with cutting units mounted on it, each of which contains a mounting plate fixed to the drum, and a cutting tooth mounted detachably on the mounting plate, characterized in that each mounting plate with the possibility of a connector additionally pivotally mounted throwing blade from the side opposite to the cutting tooth, so that when the drum rotates in reverse azhnaya plate is a stop for the throwing vanes.

Description

The device relates to rotary brush cutters and can be used for cleaning power lines and communications, protection zones of pipelines, in the forestry complex for preparatory and auxiliary works, forestry, in particular for clearing clearings and forming mineralized strips to prevent the spread of forest fires, as well as during cultural works for cutting tree and shrub vegetation and chopping stumps.

Known fire primer-strip stripper, containing the frame, the linkage mechanism, spherical discs, milling throwers and transmission [1].

The disadvantage of this device is that for the formation of mineralized strips in the stand requires the preliminary use of additional tools that allow the removal of trees and shrubs and stumps. In addition, the efficiency of such a device during the formation of a mineralized strip decreases with the saturation of the soil with tree roots, which prevent the milling cutters from capturing and scattering the soil.

Known soil milling fire milling machine, containing a frame, cardan drive, guiding casings, milling throwers, and a milling drum with L-shaped knives installed in front of milling cutters [2].

Under growing conditions, such a device also requires the use of specialized tools for the formation of a mineralized strip, allowing the removal of tree-shrub vegetation and stumps. Negatively, its effectiveness, as well as the analogue described above, is affected by soil saturation by roots.

The closest analogue, taken as a prototype, is the working body of the machine for cutting tree and shrubbery vegetation on the root, including a rotating drum with cutting units mounted on it, each of which contains a mounting plate fixedly mounted on the drum, and a cutting tooth mounted detachably on mounting plate [3].

Such a device allows you to cut and chop wood and shrub vegetation, as well as partially remove stumps, by grinding the aerial parts. In addition, such a working body copes well with tree roots when laying a mineralized strip. However, at the same time, the efficiency and productivity of the device during the formation of the mineralized strip is relatively low due to the design features of the cutting units, which do not allow you to capture the required amount of soil and ensure its spread over the area.

The technical result, which is directed by the inventive working body of the machine for cutting wood and shrubbery and laying mineralized strips, is to increase the efficiency and productivity of the process of forming a mineralized strip, as well as ensuring ease of use.

The technical result is achieved due to the fact that on each mounting plate, a throwing blade is pivotally mounted on the side of the opposite cutting tooth in such a way that when the drum rotates in reverse mode, the mounting plate is an emphasis for the throwing blade.

The device is explained in the diagrams, where in FIG. 1 shows a general view of the device (isometry), in FIG. 2 - self-propelled chassis with a working body hung in front of it.

The working body of the machine for cutting wood and shrubby vegetation and laying mineralized strips, includes a rotating drum 1 with mounted cutting units. Each cutting unit includes a mounting plate 2, mounted on the drum 1, and a cutting tooth 3, which is detachably mounted on the mounting plate 2. On each mounting plate 2, a throwing blade 4 is additionally pivotally mounted from the side opposite to the cutting tooth 3, thus that when the drum 1 is rotated in reverse mode, the mounting plate 2 is an emphasis for the throwing blade 4.

To ensure the direction of the spreading of the soil, the working body can be equipped with guards 5, and for the implementation of the directional felling of trees bending-supporting device 6.

The working body can be mounted directly on the self-propelled chassis 7 by means of a linkage, as well as on the manipulator or the rotary boom of the self-propelled chassis.

The operation of the device is as follows. Initially, woody and shrubby vegetation is removed and the soil is preliminarily prepared for laying a mineralized strip. For this, the self-propelled chassis 7 slowly moves over the area of the future mineralized strip with the drive of the drum 1 turned on. The rotating drum 1, using cutting units, felling trees, cutting the bush, and also chopping them. Having processed a section of a certain length, the self-propelled chassis 7 moves in the opposite direction (movement can be carried out both after a turn and in reverse), loosening the soil by deepening the cutting units of the rotating drum 1. At the same time, stumps and roots close to the surface are also crushed soil, and regrinding the remains of fallen trees and cut bushes. It is advisable to carry out operations to remove trees and shrubs and preliminary preparation of the soil for laying a mineralized strip with dismantled throwing vanes 4 in order to reduce their wear.

After performing the above operations, throwing blades 4 are installed on mounting plates 2 and proceed with the direct laying of the mineralized strip. To do this, turn on the drive in reverse mode, forcing the drum 1 to rotate in the opposite direction, and deepen the working body into the soil with the slow movement of the self-propelled chassis. Each throwing blade 4, abutting against the mounting plate 2, grabs a portion of the soil and throws it away from the self-propelled chassis. When installing the guards 5, you can adjust the direction of spread of soil over the area.

If it is necessary to cut or chop the trees, shrubs, stumps and roots remaining after previous operations, the drive reverse mode is switched off, turning it into normal mode. With this work, the throwing blades 4 do not have a stop and, when interacting with the ground object, they are deflected, allowing the cutting teeth 3 to freely cut into the wood.

Thus, the inventive working body of the machine for cutting tree and shrubbery vegetation and laying mineralized strips can increase the efficiency and productivity of the process of forming a mineralized strip and ensure ease of use. The increase in the efficiency and productivity of laying mineralized strips is due to the intensification of the process of spreading the soil due to the additional installation of 2 throwing vanes on the mounting plates 4. The convenience of operation is ensured due to the fact that there is no need to use various specialized tools for laying the mineralized strip in the forest stand. All necessary operations can be performed by one working body.
