I

The invention relates to forestry and can be used for the continuous uprooting of stumps in a row tree planting.

Known stump lifter containing frame with a swivel with a tractor and a U-shaped carrier, at the apex of which there is a pulling tooth, and on the sides - loosening teeth 1J.

Also known is a grubber containing a frame mounted on a self-propelled chassis, at the apex of which there is a rotary pulling tooth, and on the sides are passive loosening teeth, and a rotation drive of the pulling tooth, having a hydraulic cylinder and a hydraulic distributor j.

However, these uproaders are characterized by insufficient efficiency of grubbing and high pulling forces, which is explained by the fact that 4fo per tractor stump when pulling through the pulling tooth, traction force of the tractor acts in the direction of its movement, i.e. lateral force that does not ensure uniformity of its roots along the perimeter, which leads to low efficiency of lifting, i.e. purity root extraction.

The aim of the invention is to increase the efficiency of grubbing by automatically turning on the drive of the writhing tooth.

The goal is achieved in that the frame is provided with a spring-loaded slider for interacting with the hydraulic distribution system and an additional loosening tooth, which is located behind the writhing tooth, which the latter is mounted on the slider.

FIG. 1 shows a rooting lifter, side view; in fig. 2 - the same, top view; in fig. 3 - node I in figure 1; in fig. 4 - the same, top view; in fig. 5 - the same, front view; in fig. 6 is a section A-A in FIG. 4. 3 The rooster consists of a wedge-shaped frame 1 installed on a self-propelled chassis, having a base plate 2. Passive loosening teeth 3 are fixed to the sides of the frame. At the top of the frame 1 there is a longitudinal fork tide 4, in the longitudinal grooves of which there is a slider 5, in the slot of which, on the horizontal axis 6 passing through the longitudinal notches 7, in tide 4 there is a crotching tooth 8. The slider 5 is spring-loaded with an elastic support, in particular spring 9; against the spring 9 along the axis of the slide 5, there is a hydraulic valve 10, c. particular spool. hydraulic cylinders 11 connecting the upper end of the pulling tooth 8 with the frame 1. At the top of the frame 1, an additional loose tooth 12 is fixed behind the pulling tooth 8. In addition, the device can be equipped with a roller 1 The rooster works as follows. The lifter is mounted on a self-propelled chassis, towed to the point of rooting and lowered to the ground in a horizontal position until it is supported on the roller 13, with all the teeth 3, 8 and 12 being sunk into the ground, and the supporting plate 2 is located relative to the ground. In the absence of stumps, the teeth produce weeding, loosening the soil, removing the rhizomes and foreign objects from it, which turn up onto the ground and with the sides of frame I move apart along the sides, clearing the passage. The grubbing tooth 8 performs the same functions, resiliently vibrating through the slider 5 on track 9. When the writhing tooth is found on the stump, the resistance of the mon is transmitted through the tooth 8, axis 6 and the slider 5 to the spring 9, which is proportional to the pressure elastically deformed. Along this, the slider 5 moves in the grooves, the tide 4 following the spring stroke until the spring 9 presses the hydraulic distributor 10. The latter switches the pressure of the hydraulic system in the hydraulic cylinder J 3. The rod of the hydraulic cylinder 11 1 is retracted, the pulling tooth 8 rotates on the axis 6, the stump is swiveled to the ground surface. Next stump. dragged along the surface of the earth and thrown off the aisle. During the grubbing, when the grunting tooth 8 is raised, the loosening tooth 12 behind it checks the condition of the soil and performs the functions of loosening. As soon as the load mon is removed from the tooth 8, the spring 9 through the slider 5 pushes it to its original position and releases the hydraulic distributor 10. The latter switches the pressure of the hydraulic system and the hydraulic cylinder 11 returns the tooth 8 to its original position. The work cycle of the upravel is repeated when the next mon. The proposed uplifter significantly improves the efficiency of stump pulling due to the automatic turning on of the drive for turning the pulling tooth and turning it in mon. Claims of invention A rooting device containing a wedge-shaped frame mounted on a self-propelled chassis, at the apex of which a rotary tooth is located, and on the sides are passive loosening teeth, and a rotation driver of a pulling tooth, having a hydraulic cylinder and a hydraulic distributor, characterized in that, in order to increase the efficiency of uprooting by automatically turning on the drive of rotation of the pulling tooth, the frame is equipped with a spring-loaded slider for interacting with the hydraulic distribution and additional ripper It is a tooth that is located behind the tooth with a tooth, the latter being mounted on a slider.
