Description

The invention relates to agricultural machinery and is intended for the mechanical drive of a rotary subsoil cultivator when loosening and mixing (milling) of the inner soil layers.

Known rotary cultivator podgumusnogo soil layer containing a disk sowing, undercover milling cutter and its drive (RF patent for the invention No. 2273120, A01B 33/02 (2006.01), 49/02 (2006.01). 2006 - prototype).

The closest in technical essence to the claimed object is a device for rotational subsoil loosening, containing rotational slitherer, subsoil milling machine and its drive (decision to grant a patent for the invention of August 3, 2009 by application No. 2008118583/12 (021536), A01B 33/02 ( 2006.01), dated May 08, 2008 - analogue).

This device has disadvantages:

- Slitherese of a rotary subsoil cultivator rotates against the direction of movement of the unit. Therefore, in the process, all the soil from the gap processed in the soil layer is removed to the surface, which leads to additional energy costs. In addition, the removal of soil from the lower layers of soil to its surface by slimez reduces the quality of soil treatment by a device for rotational subsoil loosening, causing increased heterogeneity of the surface, and also gives an unfavorable effect of diluting the humus layer of the soil that was carried out upward by the parent rock.

The technical problem, which is solved by the present invention, is to reduce the removal of soil by slime from the lower processed soil layer to the surface during operation of the device for rotational subsoil cultivation.

The technical result obtained by the practical use of the invention is the creation of the ability to produce a mechanical drive of the cultivator, while ensuring high quality soil treatment with a device for rotational subsoil cultivation and reduce energy costs for tillage.

To solve the technical problem, the proposed mechanical drive of the device for rotational subsoil loosening, containing rotational shelieres with a shearer disk, annular shelieres with an intermediate gear of the internal gearing, the leading, centering and driven gears of the cultivator drive, is equipped with an intermediate gear of the drive, which is mounted on the alkali disk with gearing with an internal intermediate gear of a drive of annular shelihere and a driven gear of a drive of an underground soil cultivator, kol Central slitherese is equipped with external cutting bodies located between the external cutting bodies and containers for receiving soil; it is equipped with teeth and troughs of gearing of a leading, intermediate internal gearing, an intermediate and driven gear of the drive of the underground soil cultivator, made pairwise complementary alternately left and right along the gearing of each gear leading intermediate internal gearing, intermediate, centering and driven gears of the drive of the underground soil cultivator, which are equipped with indigenous supporting surfaces made in the form of segments of a cylindrical surface along which mutual run-in of ring shearer drive elements takes place, which is formed by the pitch circle of each gear located complementary alternately on the left and on the right opposite to the corresponding tooth and gear engagement depression.

The invention is illustrated by the accompanying schemes, where

figure 1 shows the proposed mechanical drive of the device for rotational subsoil loosening, side view;

figure 2 shows the proposed mechanical drive of the device for rotational subsoil loosening, rear view;

figure 3 - gear drive of the cultivator, isometric view.

The mechanical drive of the device for rotational subsoil loosening but Figs. 1, 2 is a rotational slitherez 1 containing a slitherese disk 2, an annular slitherese 3 with external cutting bodies 4 located between the external cutting bodies 4 containers for receiving soil 5 and the intermediate gear of internal gearing 6 , pinion gear 7, pinion gear 8 of the drive of the subsoil cultivator of the milling machine 9, an intermediate gear of the drive 10, the centering gear 11.

The gear drive of the cultivator of FIG. 3 is equipped with gear teeth 12, gear cavities 13, and bearing surfaces 14.

The proposed mechanical drive device for rotational subsoil tillage works as follows.

When the unit moves along the field from left to right in Fig. 1, the cultivator is buried in the soil. The torque from the driving gear of the drive 7 of the rotary glue 1 is transmitted to the intermediate gear of the internal engagement of the ring glue 3, from it to the intermediate gear of the drive 10, through which it goes to the driven gear 8 of the drive of the underground soil cultivator (milling cutter) 9, which rotates counterclockwise according to FIG. .1, loosens and mixes the soil in the treated layer. In the process, the annular slitherese 3 cylindrical bearing surfaces of the intermediate gear of the internal gear 6 is based on the cylindrical bearing surfaces of the drive 7, driven 8 and centering 11 of the gear drive of the cultivator 9 and centered in the working position. Due to the fact that the gear teeth of the drive gear are equipped with gear teeth 12, gear troughs 13, supporting surfaces 14, complementary alternately left and right along the gear gear, the ring slit 3 and the driven gear 8 are fixed from moving in the direction perpendicular to FIG. 1 along the shaft subsoil cultivator milling machine 9.

The arrangement of the engagement elements is selected so as to ensure the operability of the drive, excluding the contact of the kinematic elements having the same directions of rotation.

In the process of operation of the drive, the annular slitherese 3 rotates clockwise in FIG. 1 and cuts off soil chips, the thickness of which is determined by the feed of the device in the direction of processing, by external cutting bodies. Shavings in the form of crushed soil enters the soil receiving container 5 located in front of the outer cutting body 4 of the annular cherezer 3. After the next filled soil receiving vessel 5 passes the lower part of the circumference path of the annular cherezer 3, the soil is thrown by centrifugal force into the space at the bottom of the slit, freed by a forward slitherese. The removal of soil to the surface from the lower treated layer does not occur.

The use of new elements in the form of an intermediate gear of the drive, which is mounted on the shearer drive with gearing with the internal intermediate gear of the ring shear drive and the driven gear of the cultivator, teeth and troughs of the drive of the leading, intermediate internal gearing, intermediate and driven gear of the cultivator, made pairwise complementary alternately left and right along the gearing of each gear, drive, intermediate internal gear, intermediate, centering and driven thorns of the drive of the cultivator equipped with cylindrical supporting surfaces made in the form of segments of a cylindrical surface, along which there is a mutual run-in of the drive elements of the ring shear, which is formed by the pitch circle of each gear, complementary alternately left and right opposite to the tooth and gear engagement depression, allows mechanical drive of the cultivator without soil removal to the surface from the lower cultivated layer to the surface with high quality tillage, as by replacing the rotation of the annular shelherez against the direction of movement of the aggregate by the rotation in the direction of the movement of the aggregate, it becomes possible to unload the soil cut by the annular slitherez 3 and entering the reservoir for receiving soil, inside the slot into the space at the bottom of the slit, freed by the slanting ahead, and also reduce costs energy for tillage.
