The invention relates to tools and machines for the cultivation of smoked land and can be used in the forest industry.

There is a well-known lifting unit that is mounted in front of the tractor, the working body of which is a horizontally fixed plate, undercut, of the roots of a bush 1.

The disadvantage of this device when pruning shrub root systems is the lack of lifting of roots and stumps to the ground. This leads to large additional costs when performing subsequent operations to separate the root wood from the soil.

The known flat-cutter is working, the working equipment of which consists of racks, a flat knife with vertical ribs, and is intended for trimming the root system of a shrub and lifting stumps and woodlands on reclaimed land x 2.

A disadvantage of the known device, as shown by its testing of cutting root systems of a shrub, is the poor quality of uprooting; uprooted and raised to the surface of the roots after the passage of the lifter remain woven

among themselves, the gaps between them are clogged with earth, especially on the connected, sodded. soils. This requires, during subsequent operations to separate the wood from the soil, significant additional costs for the deformation of the cut formation, elimination of large root plexuses. In addition, when the blade of the flat knife is blunting during operation, especially on mineral soils, the cutting of the cut layer is observed, which leads to violation of the technological process and reduction in the quality of work performed.

The purpose of the invention is to increase the quality of uprooting.

The goal is achieved by the fact that a rotor is mounted on the racks of the lifter, which has fangs and throwers located radially relative to its axis, the fangs being located between the vertical edges of the flat knife and the throwers between the rotor fangs.

The length of the canines is longer than the length of the throwers.

Claims (2)

FIG. 1 shows a rooting lifter, side view; in fig. 2 is a view A of FIG. 1. The rotor includes a frame 1 with racks 2 fixed on it with the help of pins 3 and fastening screws 4. A flat knife 5 with vertical ribs 6 is fixed on the racks, and above it is a rotor with fangs 7 placed between the vertical ribs. Between the tusks on the rotor there are throwers 8, the blades diameter of which is smaller than the diameter of the tusks 7. The rotor receives rotation from the hydraulic actuator 9. Roofing equipment is visited on the axles 10 of the tractor I and raised to the transport position by hydraulic cylinders 12 for raising and lowering the frame. Rooster works as follows. When moving on-site, where the ground scrub is cut, with the help of hydraulic cylinders 12, which are in the floating position, the flat knife 5 of the upraiser is dug into the soil, saturated with roots. As a result of the interaction of the working equipment of the lifter with the processed medium, the soil layer is cut with root systems with a flat knife 5 and lifted along vertical ribs 6. The shrub roots rest on the surface of the vertical ribs 6 while lifting the strata. The fangs 7 rotate along the movement of the digger. combing 5 pieces of roots cut by a flat knife, tearing apart the root plexuses resting on the surface of vertical ribs 6, while the layer is loose and deformed. The location of the canines 7 between the ribs 6 facilitates the work of the canines, since the formation hangs on the edges 6, and between its lower plane and the upper plane of the knife 5 there is free space, i.e., the canines operate in the cropped layer and do not tear the roots off the soil mass. The loosened soil, turf, and broken roots then fall into the working zone of the throwers 8 and are constantly thrown by their blades onto the newly processed strip. Thus, the unloading of the trimmed mass in front of the working member is prevented. Fang diameter of the rotor is larger than the diameter of the blades of the metatelek, which at first makes it possible to deform the undercut formation, raise and break (kill) the roots, and then transfer the mass to the past band, facilitating the work of throwers. Screws 4 regulate the angle of inclination of the knife relative to the frame of the uplifter and, thus, the depth of the undercut formation, which depends on the depth of the main mass of root systems and is in the range of 20-30 cm. This uplifter design provides the required quality of scrub systems. After the passage of the lifter, the roots, which are well separated from the soil, are not connected to each other and do not impede further processing of the plot. The unloading of the undercut formation is eliminated, the reliability of the technological process and labor productivity increase by 1.2-1.4 times. Claim 1. Grubber comprising a frame with struts on which a flat knife having vertical ribs is fixed and hydraulic cylinders for raising and lowering the frame, characterized in that, in order to improve the quality of uprooting, a rotor is mounted on the struts which has fangs located radially relative to its axis and throwers, with the canines located between the vertical edges of the flat knife, and throwers between the canines of the rotor. 2. The hooker according to Claim 1, characterized in that the length of the canines is longer than the length of the throwers. Sources of information taken into account in the examination 1.
