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.

Known plow for work on clearings, including a frame and mounted on it a plow spatial rack with plowshares and dumps, converging forward in the form of a wedge (G.A. Laryukhin and other Mechanization of reforestation. M: Forest industry, 1967, p. 110 -111, Fig. 19). Disadvantage: when plowing on unforested cutting, the plow does not overcome obstacles and therefore is inconvenient in operation and has low reliability.

A technical solution is known according to patent RU 2318369 A01G 17/00, A01B 13/00, 2008, according to which the forest plow includes a frame mounted on it with a plow stand with a front edge in the form of a knife with a negative cutting angle, plowshares and dumps, converging forward and in the form of a wedge, as well as a chipper attached to the top of the plow rack. With its frame, the plow is connected to a tractor equipped with a mounted hydraulic system. A chipper moving at the level of the soil surface unfolds the felling residues encountered. Disadvantage: a large number of obstacles encountered at the level of movement of the plow, increases the load on the plow rack, the design has low wear resistance and durability.

The closest analogue is the technical solution according to patent RU 126552 U1 A01B 13/00 (2006.01), publ. 04/10/2013, in which the forest plow includes a frame, a plow stand fixed to it with a front edge in the form of a knife with a negative cutting angle, a ploughshare and dumps converging forward in the form of a wedge, and also 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, moreover, the chipper body width exceeds the width of the plow along the dumps, and the front face of the plow stand touches the chipper bottom.

Disadvantage: when driving along an undisturbed and 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, shrub plants, 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. Braking by young forest shoots, bushes and grass collected along the way increases the wear of the plow structure, in particular the plow stand, blunts the share, reduces the life of the plow. In addition, 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, it needs additional reinforcement.

The disadvantages of the known utility model are eliminated by the claimed utility model, the design of which is provided for cutting wedges that are installed in the lower part of the chipper to eliminate obstacles at the soil level. The front part of the plow is a chipper, which consists of a body and a weighting filler. Unlike the prototype, the chipper body is made in the form of a multifaceted prism with a beveled bottom edge, which is a more technological form for the manufacture of a welded structure. The chipper is rigidly connected by a frame to a plow stand. The frame connecting the plow stand and the chipper is reinforced with additional planks that diverge as a fan, located in the same plane symmetrically at an acute angle from the plow stand to the chipper. The central plank of the frame is made of two channel strips, rigidly fixed to each other, and on both sides is strengthened by two additional planks 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 and two side ones. The vertical axis of symmetry of the center cutting wedge and plow rack are in the same plane. The height of the central scoring wedge is greater than the plow rack to cut through the turf, the remains of the root system, protecting the plow rack from damage. The central cutting wedge does not touch the plow stand with its rear face so that the collected grass will fall down without 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 better, even, even depth, and the durability and wear resistance of the plow structure are increased, increasing the service life and reducing the number of breakdowns. Dumps and shares are fixed with countersunk bolts, which are additionally fixed, for example, by welding, which increases the reliability and strength of the structure, since during operation these parts experience the greatest load. A bracket in the form of a rectangular frame for aggregation with a large number of tractor brands is installed on top of the chipper, which increases the versatility of using the plow.

The technical result of the utility model is to increase the durability of the forest plow by reducing the wear of the structure 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 is made in the form of a multifaceted prism with a flat bottom, the bottom of the chipper is equipped with scoring wedges from the bottom: central, located in the same plane with the plow stand, and side, symmetrically located to the center of the chipper, There is a spatial interval between the rear edge of the central scoring wedge and the plow pillar, while the protrusion of the rear edge of the central scoring wedge is larger than the protrusion of the plow pillar, and the plowshares and dumps are fixed with fixed fixed countersunk bolts.

An example implementation.

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 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 strips that diverge as a fan, located in the same plane symmetrically at an acute angle from plow rack to the chipper. The central strip of frame 1 is made of two channel strips, rigidly fixed to each other, for example, by welding and from two sides is strengthened by 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 O9G2S.

The forest plow is attached to the tractor by a cable for the bracket 10 and is located at some distance from it. During the movement, the central 7 and lateral 9 cutting wedges on 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. The plow stand 2 cuts the soil layer vertically, the left and right shares 3 cut the layer horizontally on both sides of the vertical cut, and the dumps 4 shift the cut layers to the sides, forming a furrow. The chipper 5 drags along the soil, pushing the chopping residues to the sides with its lateral surfaces, the bottom beveled edge 6, additionally cutting the turf and the rest of the grass with the cutting wedges 7 and 9. When meeting with the stumps, the chipper 5 is shifted to the side itself, removes the share 3 and dumps from them 4 plows, preventing their damage. When the bump is hitting a lying log, the plow rises, slides along the log first with scoring wedges 7, 8, and then the lower edge of the plow rack 2, while the ploughshare 3 and the dumps 4 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.
