Description

The utility model relates to forestry, in particular to plows for tillage on clearings, and can be used to prepare soil for planting forest crops, as well as to create fire-resistant mineralized strips.

The closest analogue is the technical solution according to patent RU 126552 U1 A01B 13/00 (2006.01), publ. 04/10/2013, according to which the FOREST Plow includes a frame mounted on it with a plow stand with a front face in the form of a knife with a negative cutting angle, a ploughshare and dumps converging forward in the form of a wedge, as well as a chipper attached to the top of the plow stand, characterized in that the chipper is made in the form of a streamlined flat-bottomed body, with the chipper body width exceeding the plow width along the dumps, and the front face of the plow stand touches the chipper bottom. The forest plow is attached to the tractor by a cable behind the ear in the frame and is located at some distance from it.

Disadvantage: when driving along an undisturbed, or even uprooted clearing, the plow requires increased attention from the tractor driver and constant maneuvering, in addition, the remains of the root system, young forest growth, shrubs, grass, which, when gathered in large volumes, are dragged by the plow interfere with the movement of the plow , slows down the movement and affects the quality of the row furrow. Inhibition of the plow by the listed obstacles at the soil level increases the load on the frame connecting the plow stand with the chipper; working on a bend, as well as on the ear of the front frame. In addition, not all tractor models allow you to attach a forest plow to a specified ear. In this case, it is necessary to mount an additional device from improvised means, which affects the reliability, the strength of the connection between the plow and the tractor and the universality of operation of the known design.

The disadvantages of the known utility model are eliminated by the claimed utility model, the design of which provides a universal mount that allows you to aggregate a forest plow with any make of tractor. For this, in addition to the ear, a bracket is installed on top of the front frame on the chipper, for example, with a section in the form of a hollow rectangle. The bracket is mounted on the chipper to increase the versatility of using a forest plow, for its aggregation with a maximum number of tractor brands.

The technical result of the utility model is to increase the versatility of the design during operation.

The technical result is achieved by the construction of a forest plow, including a frame, a plow stand fixed to it with a front face in the form of a knife with a negative cutting angle, a ploughshare and dumps converging forward and in the form of a wedge, as well as a chipper attached to the top of the plow stand, characterized in that the chipper on top is equipped with a bracket for aggregation with a tractor.

The essence of the technical solution is illustrated by images, where in Fig.1 shows a top view of a forest plow; in FIG. 2 is a side view, FIG. 3 is a bottom view, FIG. 4 - section AA through the bracket for aggregation with a tractor, where

1 - a frame connecting a plow rack and a chipper;

2 - plow stand;

3 - ploughshare;

4 - dumps;

5 - chipper;

6 - the lower edge of the body of the chipper;

7 - central cutting wedge;

8 - the rear edge of the Central cutting wedge;

9 - side cutting wedge;

10 - bracket for aggregation with a tractor;

11 - ear in the front frame of the chipper.

Implementation example

A plow stand 2 is mounted vertically on the plow frame 1, on which plowshares 3 and dumps 4 are mounted on both sides. The chipper 5 is a welded metal case with a filler that serves as a weighting agent. The body of the chipper 5 is made in the form of a multifaceted prism with a beveled bottom edge 6. The chipper 5 is attached to the plow stand 2 using the frame 1. The frame connecting the plow stand and the chipper is reinforced with additional slats that diverge as a fan, located in the same plane symmetrically at an acute angle from a plow rack to a chipper. The central strip of frame 1 is made of two channel strips, rigidly fixed to each other, and on both sides is reinforced with two additional strips of single channels. The vertical plow stand touches the end of the chipper along the corner of the polyhedron. The width of the body of the chipper does not exceed the width of the plow along the dumps, so as not to inhibit the movement of the plow. Cutting wedges are installed in the lower part of the chipper: the central 7 and two side 8. The height of the central cutting wedge is greater than the plow rack to cut through the turf and the remains of the root system, protecting the plow rack from damage. The central cutting wedge 7 with its rear face 8 does not touch the plow stand 2, so that the collected grass falls off before reaching the plow stand. This frees up the path of the plow stand, the movement of the plow becomes more free. Thus, the plow furrow turns out to be of a better, even, even depth, and the durability and wear resistance of the plow structure increases, increasing the service life and reducing the number of breakdowns. Dumps 4 and share 3 are fixed with countersunk bolts, which are additionally fixed by welding, which increases the reliability and strength of the structure, since during operation these parts experience the greatest load. The main body parts are made of structural steel, for example, St3, the bottom of the chipper body, the cutting wedges experiencing a large shock load are made of special steel, for example 09G2S. The bracket 10 is made by welding, for example, from the channel 12, and is rigidly fixed to the upper part of the chipper.

The forest plow is attached to the tractor by a cable for the bracket 10 and is located at some distance from it. In the process of movement, the central and lateral cutting wedges of the bottom of the chipper cut grass, shrubs, young shoots, turf, the remains of the root system, facilitating the movement of the plow and reducing the load on the plow rack. A plow stand cuts vertically a layer of soil, the left and right plowshares cut the layer horizontally on both sides of the vertical cut, and the dumps shift the cut layers to the sides, forming a furrow. The chipper 5 drags along the soil, pushing the logging residues to the sides with its lateral surfaces, the lower edge 6 and the cutting wedges 7 and 8. When it encounters the stumps, the chipper 5 is shifted to the side itself, removes the share 3 and the dumps 4 of the plow from them, preventing their damage. When the bump is hit by a lying log, the plow rises, slides along the log first with cutting wedges 7, 8, and then the lower edge of the plow rack 2, while the plowshares and dumps located above pass over the log.

The plow can be used for tillage on clearings, including for preparing the soil for planting forest crops, as well as for creating fire mineralized strips.
