RU199669U1 - WORKING SECTION FOR STRIP TILLAGE AND SEEDING - Google Patents

Abstract

The utility model relates to soil cultivation seeding machines with two or more working bodies of various types. The working section for strip tillage contains a frame on which two spherical discs with opposite angles of attack are symmetrically installed. Behind the spherical discs on the bracket there are two loosening racks with pipelines. The working surface of the loosening racks is made in the form of flat removable plowshares attached to the racks in a vertical plane with opposite angles of attack facing outward, less than the angle of friction of the soil against steel. A paw is installed behind the loosening stands with the ability to move in height relative to the loosening stands. The share is equipped with a seed tube for simultaneous sowing of seeds. A packer roller equipped with a position regulator is installed behind the tine. The working section is attached to the main transverse frame of the tillage machine by means of a spring-loaded parallelogram mechanism. The useful model ensures that the seedbed is not destroyed when the loosening tines are approached and the seeds are sown at the same time.

Description

The utility model relates to tillage machines with two or more working bodies of various types for soil cultivation, fertilization and sowing of seeds.

Known working section for strip soil cultivation, containing a frame on which two spherical discs with opposite angles of attack are symmetrically installed for cutting and retraction towards the stubble, two loosening stands with pipelines to create a deep-processed background, behind which a flat-cutting paw is installed with the possibility of adjusting the depth of processing preparing the seedbed for subsequent sowing (patent for a useful model RU 152987, 2015107078/13, filed 02.03.2015, publ. 27.06.2015, bul. No. 18).

The disadvantage of this model is the impossibility of converging the loosening racks due to the destruction of the seed bed at a loosening depth of more than 18 cm and the inability to simultaneously sow seeds, for example, during spring strip soil preparation with sowing industrial crops.

The technical task of the utility model is to exclude the destruction of the seed bed when the loosening tines are brought together to ensure the most optimal distance from the zone of the seeds to the place of placing the fertilizers, equal to 5 centimeters to the side and in depth for industrial crops, for example, during spring strip soil preparation with loosening to a depth more than 18 cm and their simultaneous sowing.

The technical problem is achieved by the fact that in the working section for strip tillage and sowing of seeds, which contains a frame, on which two spherical discs with opposite angles of attack are symmetrically installed for cutting and removing to the side of the stubble, two loosening stands with fertilizer lines to create a deep-processed background, for with which a paw is installed with the possibility of adjusting the working depth, preparing the seed bed for sowing, in contrast to the prototype, the working surface of the loosening racks is made in the form of flat removable plowshares attached to the racks in a vertical plane with opposite angles of attack facing outward, less than the angle of friction of the soil about steel, and the share is equipped with a seed tube for simultaneous sowing of seeds.

Due to the design of the working surface of the loosening tines in the form of removable plowshares attached to the tines in a vertical plane with opposite angles of attack facing outward in size less than the angle of friction of the soil against steel, the soil in front of the loosening tines is cut off by the plowshare and pulled away from the tines, creating a loose soil layer to the depth of travel of the loosening tines for the passage of plant root systems, while not destroying the soil in the area of the seedbed between the tines.

The essence of the proposed technical solution is illustrated by drawings:

FIG. 3 shows a view B on the loosening stands.

FIG. 4 section A-A of a loosening rack.

The working section for strip tillage contains a frame 1 on which two spherical discs 2 with opposite angles of attack are symmetrically installed. Behind the spherical discs 2 on the bracket 3 are fixed two loosening racks 4 with pipelines 5, adjustable in height relative to the racks 4 (Figs. 1, 2 and 3). The working surface of the loosening racks 4 is made in the form of flat removable plowshares 6 attached to the racks in the vertical plane (Fig. 4) with opposite angles of attack facing outward, less than the angle of friction of the soil against steel ϕ. A paw 7 is installed behind the loosening racks 4 with the ability to move along the height relative to the loosening racks 4. A seed tube 8 is attached to the paw rack 7 for simultaneous sowing of seeds. Behind the paw 7 is a packer roller 9 equipped with a position controller 10 (Figs. 1, 2). The working section is attached to the main transverse frame 11 of the tillage machine by means of a spring-loaded parallelogram mechanism 12.

The technological process of the working section for strip tillage and sowing of seeds is as follows.

When moving the working section for strip soil cultivation and sowing seeds, the spherical discs 2 are cut off and removed to the side of the stubble to prevent clogging of the loosening stands 4 with crop residues. Loosening shanks 4 are buried in the soil to the depth of the main tillage and loosen the soil. Flat plowshares 6 on loosening stands 4 with front cutting edges cut the soil layer in a vertical plane, directing the soil destruction zone outward from the strip axis and without destroying the soil in the seedbed area. At the same time, liquid or solid mineral fertilizers are supplied through the pipelines 5. The depth of fertilization is regulated by adjusting the height of the fertilizer lines 5 relative to the racks 4 so that the fertilizers are placed at a depth of 5 cm below the depth of the paw 7. The plow 7, installed at the sowing depth, cuts the soil layer and prepares the seedbed for sowing industrial crops. The seed is fed through the seed tube 8, which is attached to the tine post. The packer roller 9 produces compaction, leveling of the processed soil strip. The position controller 10 provides the setting of the required depth of soil cultivation by the loosening tines 4. The spring-loaded parallelogram mechanism 12 ensures the copying of the field relief and the necessary force for deepening the working bodies.

The working section for strip soil cultivation and sowing of seeds ensures that the destruction of the seedbed is avoided when the loosening tines are approached to ensure the most optimal distance from the area of the seeds to the place of placing the fertilizers, equal to 5 centimeters to the side and in depth for industrial crops, for example, during spring strip preparation soils with loosening to a depth of more than 18 cm and their simultaneous sowing.
