Description

The invention relates to forestry production, in particular, tools for uprooting stumps.

The purpose of the invention is to increase productivity and quality of work.

FIG. 1 shows a rooting device, a general view; in fig. 2 - technological scheme of rooting mon.

The rotor includes frame 1, middle tooth 2, mounted on a horizontal transverse axis 3 and controlled by a hydraulic cylinder 4. On both sides of the middle tooth 2 are lateral pivoting teeth 5, made saber-shaped with pointed outer lateral edges and in the lower extreme position they are offset down and forward relative to the middle tooth 2. The lateral rotary teeth 5 are fixed on the crankshafts 6, and the latter are mounted on the frame 1 in bearings 7. The lateral rotary teeth 5 are controlled by hydraulic cylinders 8.

Rooster works as follows.

When stumping, the middle tooth 2 and the side teeth 5 are set to the lower extreme position, the frame 1 of the upholster is lowered, and all three teeth are buried under the stump that is rotated. Due to the fact that the side teeth 5 are displaced downward and brought forward relative to the middle tooth 2, they are well buried under the stump.

When the teeth 2 and 5 are completely buried, initially the hydraulic cylinders 8 drive the lateral teeth 5, which, through the crankshafts 6 rotating in the bearings 7, rotate in the vertical-transverse plane of the lateral teeth 5, which

The outer side edges cut the paw roots of the mon and raise them.

After cutting and tearing off the side roots of the mon, the middle tooth 2, controlled by the hydraulic cylinder 4, lifts the whole mon and, in combination with the tractor pushing force, the uprooted stump is taken out of the cleared strip.

In the case when all three teeth - medium 2 and two lateral 5 are aligned in the horizontal plane, the instrument can work as a picker-gatherer, i.e. to clear the bands from logging residues, deadwood, logs and shift them beyond the limits of the treated strip.

Due to the complete cutting of the root paws of the stumps and their displacement from the strip being cleared, a high-quality preparation is provided, and clearing the mon in one technological step increases the productivity of work.

Claims (2)

1. A forklift including a frame with middle and side rotatable teeth mounted on it and their hydraulic actuator, characterized in that, in order to increase productivity and quality of work, the side rotary teeth are mounted on the frame that can be rotated in a vertically transverse plane by means of cranked shafts, while their outer side edges are pointed. 2.Korchevatel under item 1, characterized in that the lateral rotary teeth are made saber-shaped and in the lower extreme position are shifted down and forward relative to the middle rotary tooth.
