Abstract

Use: Used in the forestry industry for clearing. SUMMARY OF THE INVENTION: in front of the dozer blade 3 on the brackets 9, rigidly mounted on the upper longitudinal beam 8 of the blade 3, a writhing jaw 4 is pivotally mounted with a concave pressure plate 7 in the lower part of the rear side. When the rods of the uprooted hydrocracker indra 6 are extended, the stump is uprooted from the ground, and when the rods are pulled in, the uprooted stump is clamped between the pressing plate 7 of the upright jaw 4 and the bulldozer blade 3 and transported from the developed area in the right direction, where the stumps are stacked in heaps. 3 ill.

Description

FIG. Z

FIELD OF THE INVENTION This invention relates to attachments for clearing forest areas for agricultural land, routes of forest roads, for rooting out stumps in the preparation of pneumo-root wood and can be used in the forest industry.

The purpose of the invention is to increase operational efficiency.

Figure 1 shows a self-propelled chassis with a working body for clearing forest areas, front view; figure 2 working body during the uprooting Mon; in Fig.Z - the same when capturing and transporting Mon.

The working body for clearing forest areas is hung on the frame of the self-propelled chassis 1 and includes a pushing frame 2, a bulldozer blade 3, a writhing jaw 4, power cylinders 5 for raising and lowering the pushing frame 2 and uprooted cylinders 6 for turning a writhing jaw 4. A writhing jaw 4 from the back in the lower part it is made with a concave clamping plate 7. On the upper longitudinal beam 8 of the dozer blade 3, brackets 7 are installed with eyes 10 at the ends for installing an upright jaw 4.

The uproar cylinders 6 are mounted on the front sheet of the dozer blade 3 below the suspension point of the wriggling jaw 4, and the rod side is connected to the lower part of the wriggling jaw 4. The pressure plate 7 is made in a concave shape for better contact with captured objects of work (stumps, stones, deadwood) have a corrugated or serrated work surface.

The working body for clearing forest areas works as follows.

Before writhing up, the wriggling jaw 4 must be in working position

- rods of uprooted hydraulic cylinders 6 watts chickpeas. By moving the self-propelled chassis 1 forward, the writhing jaw 4 is deepened under the writhing stump and the bulldozer blade 3 is lowered to the ground (Fig. 2). Nomination

the rods of the uproarning cylinders b turn the writhing jaw 4 upward relative to the dozer blade 3 and the stump is turned out of the ground. Then, if necessary, the uprooted stump is clamped between the frontal part of the blade 3 and the concave clamping plate 7 of the wriggling jaw 4, it is lifted above the ground by lifting rams 5 of the pushing frame 2 and transported to the place

storage (Fig. 3). Then the cycle of work is repeated. When working with a dozer blade 3 (leveling the ground), the writhing jaw 4 rises.

Claims (1)

The claims The working body for clearing forest areas, including a pushing frame with a bulldozer blade and a pivotally mounted jaw, as well as power cylinders for their control, including and, in order to improve work efficiency, the bulldozer blade is equipped with a longitudinal beam, and the writhing jaw is equipped with a concave-shaped clamping plate in the lower part on the back side and is pivotally mounted in front of the bulldozer blade on brackets rigidly fixed to the longitudinal beam of the bulldozer blade.
