Abstract

The working body of the machine for cutting wood and shrubbery vegetation, including a housing with a drive and a shaft, on which a disk with axles and pivotally mounted flexible cutting devices mounted on it, which are attached grinding and cutting elements, characterized in that each grinding element is made in the form plates having a cutting edge on the side corresponding to the direction of rotation, while coaxially with the shaft mounted an additional cutting body in the form of a circular saw, located above the flexible x mowing devices.

Description

The working body of the machine for cutting wood and shrubby vegetation can be used in the cleaning of power lines and communications, in the timber industry, forestry, as well as in cultural work.

Known working body of the machine for cutting wood and shrubby vegetation, comprising a housing with a drive and a shaft on which a disk is mounted with axes and flexible cutting devices pivotally mounted on them [1]. This working body does not provide cutting of the whole variety of diameters of trees and shrubs encountered in clearing areas, which significantly reduces the functionality of its application.

Known working body of the machine for cutting wood and shrubby vegetation consisting of a housing, drive and shaft on which a disk is mounted with axes and articulated on them by means of flexible connections cutting organs. An additional cutting flat knife mounted above each cutting body is mounted on each axis of the disk [2]. Such a working body has insufficient reliability, since the chopped wood-shrub vegetation is crushed by flat knives rigidly mounted on the rotor, which experience high dynamic loads. As a result, the wear of knives increases and the probability of failure of the entire device. In addition, the functionality of this prototype is insufficient, since cutting flat wood knives with shrubs with a diameter of more than 7 cm is problematic.

The technical result, which is achieved by the claimed working body of the machine for cutting wood and shrubby vegetation, is: expanding the functionality of the working body, increasing the reliability of the working body, reducing the required drive motor power.

A technical result is achieved due to the fact that an additional cutting body in the form of a circular saw is located coaxially with the shaft, located above the flexible cutting devices.

Figure 1 shows the working body of the machine for cutting wood and shrubby vegetation, a side view in section. Figure 2 - working body of the machine for cutting wood and shrubbery, top view. Figure 1 and figure 2 fully shows one flexible cutting device.

The working body of the machine for cutting wood and shrubby vegetation includes a housing 1 with a drive (not shown) and a shaft 2, on which a disk 3 with axles 4 is mounted, and flexible cutting devices 5 articulated thereon. Each flexible device 5 is made combined in the form of links 6, fastening between each other both grinding 7 and cutting 8 elements. Each grinding element 7 is made in the form of plates having a cutting edge on the side corresponding to rotation. On disk 3, a circular saw 9 is additionally rigidly mounted, located above the flexible cutting devices 5. The working body of the machine for cutting wood and shrubby vegetation by means of a suspension can be mounted on a self-propelled chassis (not shown). The number of flexible cutting organs is determined by the natural-production operating conditions.

The work of the proposed working body of the machine for cutting wood and shrubbery is as follows. The drive is turned on and, using the shaft 2, the disk 3 with the flexible cutting devices 5 fixed on it and the circular saw 9 begin to rotate. The working body is brought to the woody-shrubby vegetation. Cutting element 8 flexible cutting devices 5 tree and shrub vegetation is cut. Cut wood and shrubbery vegetation then falls into the zone of action of the elements 7 of the flexible cutting devices 5, as a result of which they are crushed and scattered. Tree-shrubbery vegetation with a diameter of more than 7 cm, as well as individual small trees that have not been treated with flexible cutting devices 5, then fall into the area of the saw blade 9 and are cut.

Thus, the working body provides cutting of wood-shrubbery vegetation, its shredding and scattering, as well as cutting of woody-shrubby vegetation with a diameter of more than 7 cm and small trees, due to which the expansion of the functional capabilities of using the working organ is achieved. The working body can be used on cleared areas where larger trees and shrubs and small trees are found. In addition, the reliability of the working body is increased, since when using a circular saw and flexible cutting devices, shock loads on the working body are reduced. Due to the installation of a circular saw 9 on the disk 3, lower drive motor power is required than when using flat cutting knives.
