Description

The invention relates to the forest industry and can be used in the uprooting of a series of stumps, shrubs and small trees.

The purpose of the invention is to reduce the effort during uprooting.

Figure 1 shows the lifter, a plan view; figure 2 - section aa in figure 1; on fig.Z - section bb in figure 2 on figure 4 - section bb In figure 2; figure 5 - section GG in figure 2; in Fig. 6 g, node I in Fig. 25 in Fig. 7 is node-II in Fig. 2 in Fig. 3 — section DD-D in Fig. 4; in Fig. 9, a diagram of the operation of the nodes of the uplifter.

The lifter contains a frame 1 connected to the vehicle by brackets 2-4 hinge plates, support wheels 5, cutting off the working member in the form of a stand 6 and a flat horizontal knife 7 at an angle to the horizon, and also a writhing organ in the form of connected to the horizontal knife 7 and bevelled back vertical lifting ribs. 8. On the frontal part of the horizontal knife 7 and the uprights 6 are removable cutting elements 9. In addition, the drill driver is equipped with a device for deflecting the cut stumps in the direction of travel of the vehicle, made in the form of a flat knife 10, placed rigidly with gussets 11 and 12 on racks 13 (figure 2 and 7). The pillars 13 are pivotally connected to the rods 14 and the rods 15 by means of pins 16 and 17 and the kerchiefs 18 welded to the poles 13. The front ends of the pg 14 are equipped with bronze bushings 19 and are placed together with the rods 14 on the axis x 20 of the vertical beams of the frame 1. The rods 15 are connected to the horizontal beam of the frame 1 by brackets 21 using fingers 22. The fingers 22 in the rods 15 are placed in the croutons 23, which are provided with threaded plugs 24 at the diametrical ends. Springs 25 are screwed on the plugs 24. The other ends of the springs 25 are connected by rods 15 by means of threaded plugs 26 and Tift 27 (fig.Z).

Racks 13 and ti gi 14 are additionally interconnected by power units 28 (Figures 2 and 4) by means of axes 29. Power unit 28 contains two cages 30 and 31 for fastening double springs 32, tension bolts 33 and

34 with an arm 35. The axes 29 are placed in the sleeves 36 of the uprights 13 and 14 and are interconnected by flexible ties (ropes) 37. The ends

axes 29 are provided with holes 38, into which conical pins 39 are inserted with a groove 40 for accommodating the cable 37. The free end of the conical pin 39 is threaded and

bolts 41, which, through the washer 42, clamp the rope 37 in the holes 38.

The device works as follows.

A lifter connected to the vehicle saddles a row of stumps, bushes or undergrowth. Before reaching the first mon 2-3 m, lower the lifter to the surface

writhing r yes. When the machine moves along the axis of a row of detachable cutting elements 9 of the uprights 6 and of the horizontal knife 7, the layer with the stump roots is cut along the perimeter of the knife 7 and

pillars 6. Flat knife 10 in the initial position when moving the locking unit is on the soil surface. When meeting with a stump, the cutting edge of the knife 10 cuts into the stem

Mon part is perpendicular to its axis. Upon further movement of the lifter, the stump moves away from the frame 1. The distance between the axes 20 of the frame 1 and the knife 10 increases. This further leads to the fact that the pillars 13, turning around the finger 16, change their position with respect to the tg 14 and the rods 15.

When the distance between the pillars 13 and the rims 14 is changed, the power blocks 28 enter into operation. The springs 32 of the power blocks 28 expand, thereby creating an additional load on the knife 10. A nominal load of 500 kgf occurs at the moment of the position of the axis of the mon over the horizontal knife 7. Under such a load, the root gap is stressed in the central and lateral roots. The strained fibers of the roots of the mon are easily cut off by the removable cutting elements 9 of the uprights 6 and the horizontal knife 7. However, the stump is still firmly held in the soil layer by clipped roots and fractional roots. Together with the reservoir

soil stump enters the lifting ribs 8, with which the soil layer is cut into vertical layers of smaller width. Bonding force roots mon

the formation decreases. In this case, the flat blade 10 deflects the stump more intensively in the direction of movement of the lifter. The soil in this case passes between the ribs 8 and remains in under the pneumatic ditch. Moving the mon along the lifting ribs 8 and changing the position of its axis, as well as changing the positions of the uprights 13 and 10 14, causes the angle between the knife 10 and the stem of the mon to become blunt and the knife 10 slides off the trunk. Under the action of the tensioned springs 32 of the power unit 28, the knife 10 returns to its original position. With such an impact on the stump, it completely ejects: 1 it rises from the reservoir and separates from the soil, and later, due to the retention of other stumps and the stratum, it is placed mostly more

lump on the surface of the ribbed strip. The load on the knife 10 in its extreme position is minimal, despite the fact that the springs 32 of the power unit 28 are stretched to the maximum. The maximum load on the power units 28 is limited by the ropes 37. The maximum load on the stump is reached when it approaches the vertical lift & The first ribs 8. The minimum load on the knife 10 with the greatest distance makes it easy to release it from the mon. Cutting the strained mon fibers eliminates its overhang on the horizontal knife 7 and significantly reduces the effort to cut the roots and lobes of the PM. At the same time, the cut stumps lie on the surface of the podpnevoy ditch and are not dying with soil, which facilitates their subsequent cleaning.
