Description

The utility model relates to agricultural engineering, in particular to tillage units for subsurface tillage.

Known tillage unit [Tillage unit. Patent RU No. 130183. Publ. 07/20/2013, Bull. No. 20], including a frame, a device for connecting to a tractor, a control mechanism, a support wheel, working bodies containing a rack and a flat-cutting leg, and a disk section is installed between the working bodies.

However, the known tool has a disadvantage, which can be attributed to the unsatisfactory quality of tillage.

The technical result is an increase in the quality of tillage.

The technical result is achieved by the fact that behind the working bodies, a roller prefix is installed, containing a frame, grinding and rolling rollers, rods with springs. The grinding roller contains an axle and disk rippers. Disc rippers are mounted on the axis of the grinding roller at regular intervals, and curly notches are made on the periphery of the disc rippers. The vertices located between the curly recesses are triangular and guided in different directions from the geometric axis of rotation of the disk cultivators. The packer roller contains side discs. A hollow cylinder is mounted on the side discs. On the outer surface of the hollow cylinder, at equal intervals, ring sealing elements are installed, in cross section having the shape of an equilateral triangle. On the outer surface of the hollow cylinder, pointed rippers are mounted diametrically between the annular sealing elements.

In FIG. 1 shows a combined tillage unit, side view, in FIG. 2 - roller prefix, top view.

The combined tillage unit contains a frame 1, a device 2 for connecting with a factor, a control mechanism 3, a support wheel 4, working bodies 5. The working bodies 5 comprise a stand 6 and a flat-cutting leg 7. Between the working bodies 5, at an angle to the direction of movement of the combined tillage unit , the disk section is installed 8. The disk section 8 is installed with the possibility of adjusting its position in height relative to the cutting edges of the plane-cutting legs 7 and fixing in the desired position by intovyh mechanism 9. The frame unit 1 for combined soil-working elements 5, track rollers set top box 10.

Roller prefix 10 contains a frame 11, grinding 12 and rolling 13 rollers, rods 14 with springs 15.

The grinding roller 12 contains an axis 16 and disk rippers 17. The disk rippers 17 are mounted on the axis 16 of the grinding roller 12 at regular intervals, and figured recesses 18 are made on the periphery of the disk rippers 17. The vertices 19 located between the figured recesses 18 are triangular and directed towards different sides from the geometric axis of rotation of the disk rippers 17.

The packer 13 roller contains an axis 20, side disks 21 on which a hollow cylinder 22 is mounted. On the outer surface of the hollow cylinder 22, annular sealing elements 23 are installed at equal intervals in cross section in the shape of an equilateral triangle. On the outer surface of the hollow cylinder 22, pointed rippers 24 are mounted diametrically between the annular sealing elements 23.

The roller attachment 10 is installed with the ability to copy the relief of the field surface and regulate the pressure on the soil surface.

Combined tillage unit operates as follows.

The pre-combined soil cultivating unit is coupled to the tractor by means of a device 2. The working bodies 5 are placed on the frame 1. The adjustment mechanism 3 sets the required reach of the support wheel 4 relative to the lower edges of the wings of the plane-cutting legs 7. As a rule, this distance is 30 ... 35 cm, which it is enough for destruction by ploskorezhnymi paws 8 of the plow sole, formed after processing the soil with dump plow plows. Then, by rotating the handles of the screw mechanisms 9 “left-right”, the height position of the disk section 8 relative to the cutting edges of the plane-cutting legs 7. is adjusted. As a rule, this distance does not exceed 19 ... 22 cm, i.e. the depth of soil treatment by the disk section is 8 ... 16 cm. By tightening or loosening the nuts 25 located on the rods 14, the required compression of the springs 15 is achieved, thereby regulating the pressure of the roller attachment 10 on the soil.

When moving the combined tillage unit, flat-cutting legs 7 loosen the soil and destroy the plow sole. Flat-cut paws 7 also cut weeds located in the upper (fertile) layer of soil. The disk section with 8 spherical disks additionally loosens the top soil layer to a depth of 8 ... 16 cm from the soil surface level depending on the type of soil and the required amount of loosening.

The grinding roller 12, which rotates behind the working bodies 5, copies the topography of the field surface and crushes the soil lumps in the vertical direction (“top-down”) by the disk cultivators 17 to the required depth. In this case, the triangular tops 19 of the disk cultivators 17 penetrate the soil to a certain depth, destroy the lumps of the soil, and contribute to high-quality loosening of the upper soil layer.

Next, the rotating rolling rollers 13 copy the relief of the field surface, and the annular sealing elements 23 and the pointed cultivators 24 break up the soil lumps while simultaneously leveling and compacting the field surface, preventing spraying of the upper humus soil layer. Moreover, the maximum size of the destroyed soil lumps will not exceed the minimum size of soil lumps allowed by the agrotechnical requirements for sowing.

The installation of the working bodies 5 on the frame 1 allows you to process the soil to the required depth with the simultaneous destruction of the plow sole.

The presence of the disk section 8, installed between the working bodies 5 with the possibility of adjusting its position in height relative to the cutting edges of the plane-cutting paws 7, allows you to loosen the upper soil layer to the required depth, thereby further destroying the soil lumps.

The presence of a grinding roller 12, containing the axis 16 and disk cultivators 17, on the outer surface of which vertices 19 are made of triangular shape and directed in different directions from the geometric axis of rotation of the disk cultivators 17, allows not only with high quality to destroy soil lumps remaining after the passage of the working bodies 5, but also loosen the topsoil to the required depth.

The presence of a packer roller 13, containing an axis 20, side disks 21, a hollow cylinder 22, on the outer surface of which there are sealing elements 23, in cross section having the shape of an equilateral triangle, and pointed cultivators 24, can destroy soil lumps with high quality and uniformly compact the soil with a given agronomic requirements density, prevent evaporation of moisture from the soil and the formation of cracks in the surface of the field.

The use of a combined tillage unit improves the quality of soil cultivation, improves the water regime and air conditions for the subsequent development of cultivated plants. In addition, several technological operations are performed in a single pass of the tillage unit, which reduces soil moisture losses.
