Description

The utility model relates to forestry and is intended for preparing soil for sowing forest crops.

A forest double-mouldboard mounted plow is known [Copyright certificate RU patent No. 216995, IPC class. A01B 13/02, A01G 33/00, A01G 5/062, 2023], consisting of a plow body to which an additional triangular frame is attached at an angle forward, which is covered with sheet iron at the top and bottom and is made in the shape of an iron, behind the triangular frame to the longitudinal A double-mouldboard body is attached to the timber, in front of which a cutting knife with an obtuse angle of entry into the soil is placed; behind the two-moldboard body, a plate wedge with side flat horizontal knives is attached to the main frame, the ends of which extend beyond the working grip of the plow; in the front of the main frame there is a trailed eyelet with stops , the shackle is connected to a safety wedge having a sharp leading edge; at the rear, a furrow maker is attached to the plow frame by means of a bolted connection, which has a hinge joint, a spring, a bolted rod and a support plate.

The disadvantage of the known design is the insufficient quality of creating a row for subsequent sowing of forest crop seeds.

The closest analogue to the claimed one, adopted as a prototype, is a forestry double-mouldboard mounted plow [Author's certificate RU patent No. 220357, IPC class. A01B 13/02, A01C 5/06, 2023], including a frame with a longitudinal beam, a connecting device, an additional triangular frame with an angle forward, covered at the top and bottom with sheet iron and made in the form of an iron, a double-mouldboard plow body in front of which a handle knife with a blunt blade is placed angle of entry into the soil, a plate wedge with side flat horizontal knives attached to the main frame behind the double-mouldboard body, a furrow maker attached to the back of the plow frame by means of a bolted connection, having a double-disk working body, a hinged connection, a spring, a bolted rod and a support plate.

The disadvantage of the prototype is low technical reliability with high traction resistance. It does not provide for the ability of the plow body to bypass stones that do not protrude to the soil surface from above, which increases the likelihood of breakage and reduces technical reliability. The absence of self-oscillations of the plow body does not realize the possibility of reducing traction resistance.

The technical result of the utility model is to increase technical reliability while reducing traction resistance.

The technical result is achieved due to the fact that the connecting device is made in the form of an automatic coupler, the handle of the cutting knife and the stand of the double-blade body are attached to the longitudinal beam of the frame and the shoe of the double-blade body with horizontal hinges, forming a hinged parallelogram mechanism, and the upper end of the knife handle, above the longitudinal beam, is connected to beam with an adjustable compression spring.

This set of essential features ensures that the proposed forest double-mouldboard mounted plow has new properties that differ from the prototype.

Thus, the declared features of the utility model meet the “novelty” criterion.

In fig. 1 shows a diagram of a forest double-mouldboard mounted plow, side view; Fig. 2 - view A in Fig. 1.

Forestry double-mouldboard mounted plow, including a frame with a longitudinal beam 5, a connecting device, an additional triangular frame 9 with an angle forward, covered at the top and bottom with sheet iron and made in the form of an iron, a double-mouldboard plow body 13 in front of which a cutting knife 11 with an obtuse angle of entry into the soil is placed , a plate wedge 14 with side flat horizontal knives attached to the main frame behind the double-mouldboard body, a furrow maker attached to the rear of the plow frame by means of a bolted connection, having a double-disk working body 15, a hinged connection 4, a spring 3, a bolted rod 1 and a support plate 2, wherein the connecting device is made in the form of an automatic coupler 10, the handle of the cutting knife 11 and the stand 6 of the double-blade body are attached to the longitudinal beam of the frame and the shoe of the double-blade body with horizontal hinges 7, 12, forming a hinged parallelogram mechanism, and the upper end of the knife handle, above the longitudinal beam, is connected to the beam adjustable compression spring 8.

The operation of a forestry double-mouldboard mounted plow is carried out as follows.

When the plow is operating, the frame-iron 9 cuts the roots of small shoots of shrub plants, limits the depth of the plow, and moves small stones and logging residues to the side. Next, the cutting knife 11 makes a vertical cut in the soil in front of the double-mouldboard plow body to the depth of the plowshare blade. The two-shaft body of the plow 13 with its plowshares cuts layers of soil on both sides of the cut, turns them over and takes them to opposite sides with moldboards, forming an open channel. After that, in the resulting channel of a given depth, with the help of furrows dressed with a double-disk working body 15 (Fig. 1), a row for seeds is formed, the depth of which is adjusted using a rod 1 and a spring 3 from 1 to 5 cm and a width of 2-3 cm. for further placement of forest crop seeds in it.

The following relationship exists between the essential features of the claimed device and the technical result.

The connecting device allows the plow to be used in a mounted version. Attaching the cutting knife 11 and the stand 6 of the double-mouldboard body to the longitudinal beam of the frame and the shoe of the double-mouldboard body with horizontal hinges 7, 12, forming a hinged parallelogram mechanism, allows the double-mouldboard plow body, when encountering stones buried in the soil, to deflect back and up, bypassing the obstacle from above, which increases technical reliability. The connection of the upper end of the knife handle 11, above the longitudinal beam, with the beam by an adjustable compression spring 8 allows you to regulate the actuation force of the parallelogram mechanism below the critical one, eliminating breakdowns and increasing technical reliability. Spring 8 provides self-oscillation of the cutting knife 11 and the two-blade body 13, which reduces traction resistance.
