Abstract

A flexible working body of a machine for cutting tree and shrub vegetation, including a housing with a drive and a shaft, on which a disk with axles and flexible shearing devices pivotally mounted on them is mounted, characterized in that the axes of the disk are arranged in guides radially directed relative to the shaft axis and equipped with a mechanism for their movement in these guides.

Description

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

Known working body of the brush cutter, comprising a housing with a drive and a shaft on which a disk with axles is mounted, and cutting organs pivotally mounted on them by means of flexible connections. An additional flat knife mounted above each cutting body and having a length predominantly equal to the length of the flexible connection is mounted on each axis [1]. This working body has insufficient reliability, since chopped wood-shrub vegetation is crushed by flat knives rigidly mounted on the rotor, which experience high dynamic loads, as a result of which they will quickly fail.

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 with axles and flexible cutting devices pivotally mounted on them is mounted [2]. The disadvantage of such a working body is the unchanged departure of the flexible cutting devices, and accordingly the unchanged area on which the cutting of tree-shrub vegetation occurs. When working on the cultivated area, wood and shrubbery can be unevenly distributed, by curtains. Cutting off such concentrated woody-shrubby vegetation (clumps) increases the load on the drive, and also increases the demand for drive power.

The technical result, which is achieved by the claimed flexible working body of the machine for cutting wood and shrubbery, is: increasing the reliability of the working body and reducing the required drive power.

A technical result is achieved due to the fact that the axis of the disk is placed in radially directed relative to the axis of the shaft guides and equipped with a mechanism for their movement in these guides.

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

A flexible working body 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 to them. Each flexible working body is made combined in the form of links 6, fastening between each other both grinding 7 and cutting 8 elements. Axes 4 are placed in guides 9 radially directed with respect to the axis of the shaft and equipped with a mechanism for moving them 10. A flexible working body for cutting wood-shrubby vegetation by means of a suspension can be mounted on a self-propelled chassis (not shown). The number of flexible cutting devices depends on the natural and industrial operating conditions

The work of the proposed flexible working body for cutting tree-shrubbery is as follows. The drive is turned on, and with the help of the shaft 2, the disk 3 with the flexible cutting devices 5 fixed on it starts to rotate. Flexible working body of the machine is brought to the woody-shrubby vegetation. With the cutting element 8, the woody-shrubby vegetation is cut off. The cut tree-shrub 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. With an increase in the concentration of trunks of woody-shrubby vegetation, an increase in their diameters using the movement mechanism 10, the axes 4 along the guides 9 move to the center of the disk 3. Due to this, the overhang of the flexible cutting devices is reduced.

Thus, the working body of the machine provides cutting of wood-shrubby vegetation, its crushing and scattering. Due to the possibility of changing the departure of the flexible cutting devices, the load on the working body can be varied. With an increase in the concentration of woody-shrubby vegetation, the overhang of flexible shearing devices is reduced, and thereby the load on the working body is reduced. With a decrease in the concentration of woody-shrubby vegetation, the overhang of flexible shearing devices is increased, and thereby the processing area increases. This increases the reliability of the working body. In addition, it becomes possible to install a drive with less power, as the load can be varied if necessary.
