Abstract

The invention relates to forestry and the forest industry and can be used in the peat industry, land reclamation and other areas of the industry. The purpose of the invention is the expansion of technological capabilities when cutting bushes and shoots of various thickness. The working body is equipped with a tool consisting of two disk-toothed knives with oppositely directed teeth, one of which is fixed on the support ring and the other on the movable ring of the turntable the bottom of the device in relation to the first and at the same time is a cover that closes the gear transmission of the device from clogging with 4 cut products

Description

The invention relates to the forest industry and can be used for cutting shrubs and overgrowths under power lines, in reservoir boxes when re-cultivating forest plantations, as well as in thinning the care of biogroups of trees in coniferous-leaved young.

The purpose of the invention is to expand the technological capabilities of the device when cutting bushes and shoots of various thickness.

The goal is achieved by the fact that in the center of the ring-toothed knife there is a serrated coupling half, made with a central hole.

FIG. Figure 1 shows a tool for cutting bushes and shoots with a drive when transmitting rotation to a cutting knife through a gear and a movable ring of a turntable; FIG. 2 is a section A-A in FIG. one; in fig. 3 shows a device for cutting bushes and shoots with a drive.

the cutting knife through the serrated coupling half in FIG. 4 is a section BB in FIG. 3.

The device for cutting bushes and shoots includes a housing 1, to which a turntable 2 is rigidly fixed, consisting of a stationary ring 3 and a movable serrated lance 4 To the fixed ring is attached an annular counter knife 5, and to a movable ring 4 - a cutting knife 6 to which in its center, if it is necessary to cut a thin shrub, the gear coupling half is fastened, and the gear 9 of the drive 9 engages with it.

The device works as follows.

When cutting a thick brush, gear 8 engages with a movable ring 4 of a turntable. For this purpose, the actuator 9 is pushed along the housing 1 to the edge of the turntable. The drive is then bolted to housing 1.

When cutting off a thin shrub, the bolts securing the actuator 9 to the housing 1 are removed and the drive towards the center of the turntable is moved. Then the drive is raised and lowered by gear 8 inside the toothed coupling half 7.

In the first case, the rotation from the actuator 9 and the driving gear 8 is transmitted through the movable ring 4 to the cutting knife 6, and in the second through the serrated half coupling to the same cutting knife.

When switching from the first mode to the second one, the speed increases several times. Thus, thin growth is cut off faster, which makes it possible to increase the feed rate of the working organ and to increase the productivity of mowing of tree-bush plants.
