Abstract

The invention relates to machines for uprooting stumps, shrubs and low forest during the development of land augmented land used in land reclamation for the preparation of land for agricultural use. The purpose of the invention is to increase the strength of the flared closures and reduce the energy intensity of the uprooting. The working body of the stump trimmer includes the frame 1 and the locking canines 2. On all the side surfaces of the canines, except for two central ones, plates 3 are installed. The plates are offset relative to each other. The plates are arranged in a chain or in a spiral. The roots are first cut with the plates pulled forward. Then the plates on the adjacent canines come into operation. Thus, all roots are cut mon. 1 hp f-ly, 2 ill. C /) g- -1 gb / and figure 1

Description

The invention relates to a device for uprooting stumps, shrubs and small forest during the development of arable land, used in land reclamation in the preparation of land for agricultural use.

The aim of the invention is to reduce the energy consumption of grubbing and increase the strength of the canines.

FIG. 1 shows the working body of the upravel, general view; in fig. 2 shows section A-A in FIG. I.

The working body of the upravel consists of frame I, root canals 2 and connecting plates 3. Each plate 3 connects two adjacent canines and is offset relative to the next by an amount equal to the maximum root diameter. In order to increase the best condition for cutting the roots, the plate 3 is fixed along the midline of the side surfaces of the canines 2. The plastic 3 has sharp edges on both sides. The cutting angle is selected in such a way that self-sharpening occurs when it is embedded in the ground. A wear-resistant alloy is deposited on the upper edge. Due to the large thickness of the central root and considerable efforts to cut it between the central canines, the plate is not installed.

The working body works as follows.

When approaching the stump lifter to the stump, the operator disposes the blade in such a way that the central root falls into the space between the canines 2, where there is no connecting plate. On races /

about 0.5–0.6 m from Mon, the working body is deployed in such a way as to provide the best angle for

insertion of the plate 3 into the root, and the working body is buried in the ground. When the plate 3 reaches the root, it is inserted into it from above and cuts, while the soil is an emphasis

for the root, this ensures normal cutting. After the roots pushed forward by the plates 3 are cut, the plates 3 come into operation on the adjacent canines, as they are displaced relative to the first, and the next roots begin to cut. Thus pruned all the roots before stump. Upon further movement of the tractor, the tipping occurs - or pulling out the mon under the action of the force applied from below. You can cut the roots from both sides.

1. The working body of the picker, which includes a frame with a crossbeam, rooting fangs and undercut working bodies, different By the fact that, in order to reduce the puffing capacity and increase the strength of canines, cutting the working bodies is made in the form of plates with cutting edges, the plates are installed along the middle lines of the side surfaces of canines between adjacent canines, except for two central ones. 2. The working body according to claim 1, which is based on the fact that the plates displaced relative to each other and arranged along a fir-tree or spiral. ipufZ VNIIPI.
