Description

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

Known forest two-blade mounted plow PKL-70 (Zotov V.A. et al. Mechanization of green economy: Handbook / M.: Stroyizdat, 1985, page 111), having a frame with a hinged device, a two-blade body, a cutting knife and a cutting knife. A height-adjustable support foot is installed behind the body. This plow cannot always be used to work on uncut clearings and burnt areas due to the large number of stumps, stones and other obstacles. After the passage of this plow, an unclean furrow remains, which has a bad effect on the uniformity of sowing along the embedment depth.

Known forest double-dump mounted plow (SU 152590 A1, publ. 02/12/1963), in which, in order to protect the plow from breakage when meeting with stumps and stones, as well as from excessive deepening on silty and peaty soils, on the main frame, made in the form of the longitudinal beam, a triangular frame is rigidly fixed in front of the body, tightly closed from the bottom and top, having flat knives on the sides that extend beyond the working grip of the plow and serve to cut and shift the layers, and obtain a clean furrow. This plow design provides an even furrow, but does not have a technical solution for sowing assistance.

An improved forest plow is known (RU 213599 U1, publ. 09/19/2022), consisting of a plow body, to which an additional triangular frame is attached, at an angle forward, which is closed from above and below with sheet iron and is made in the form of an iron, behind a triangular frame to a longitudinal bar a double-dump body is attached, in front of which a cutting knife with an obtuse angle of entry into the soil is placed, behind the double-dump 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 front of the main frame there is a trailing earring with stops, the earring is connected to a safety wedge having a sharp front edge; a furrower is attached to the plow frame at the rear by means of a bolted connection. The disadvantage of this design of the plow is a small adjustment range, as well as a rigid attachment of the furrower to the plow body, due to which the uniform depth of row formation is not ensured.

The closest in technical essence to the proposed utility model is an improved forest plow (RU 213599 U1, publ. 09/19/2022), the design of which is taken as a prototype.

This technical result will make it possible to adjust the depth of penetration of the working part of the furrower into the soil to maintain the uniformity of the depth of row formation, thereby ensuring more complete compliance with agrotechnical requirements when sowing forest crops.

The purpose of the utility model is to improve the uniformity of the seed placement depth. This is achieved by the fact that a furrower with a swivel joint, a spring, a bolted rod and a base plate is installed on a forestry double-dump mounted plow, which makes it possible to adjust the depth of entry of the working part of the furrower into the soil.

In FIG. 1 shows the proposed forest double-dump mounted plow, side view, which consists of a plow body 1, to which an additional triangular frame 2 is attached, at an angle forward, which is closed from above and below with sheet iron and has the shape of an iron. Behind this frame-iron, a double-dump body 3 is attached to the longitudinal beam, in front of which a cutting knife with an obtuse angle of entry into the soil is placed. Behind the double-dump body, a plate wedge 4 with side flat horizontal knives is attached to the main frame, the ends of which extend beyond the working grip of the plow. In front of the main frame there is a trailing eyelet 5 with stops. The earring is connected to the safety wedge 6, which has a sharp front edge, which cuts the root system of plants. Furrower 7 is attached to the plow frame at the rear by means of a bolted connection.

In FIG. 2 shows a furrower, front and side view, which consists of a swivel 7, a spring 8, a bolted rod 9 and a base plate 10.

Forest twin-mounted plow works as follows.

During the operation of the plow, the frame-iron 2 shifts small stones, logging residues to the side and shifts the plow body to the side when it encounters large stones and stumps, protecting it from breakage, as well as from excessive deepening. Next, the soil is cut off and, turning over, is diverted to the side by the plow body 3. After that, in the formed channel of a given depth, with the help of a furrower 7, a row for seeds is formed, the depth of which is regulated by means of a rod 9 and a spring 8 from 1 to 5 cm and a width of 2- 3 cm for further placement of forest crop seeds in it.
