Description

Combined unit for tillage and sowing

The utility model relates to agricultural engineering, in particular to combination machines having working bodies for tillage, combined with working bodies serving for other purposes and can be used for all types of primary and pre-sowing tillages, as well as sowing crops cultivated or untreated soil.

Known combined units for tillage and sowing, the contents of the frame, a tow hitch mounted on the frame with the possibility of rotation, a cultivator, a hopper for seeds, a device for preparing the soil and distributing seeds, a packer roller, supporting wheels and zagortach (see ed. Certificate. USSR No. 1470204 according to MKI A 01 B 49/04, declared on 04/27/87 and author of the USSR certificate No. 1722272 according to MKI A 01 B 49/06, declared on 14.02. 90).

The closest in technical essence is a combined unit containing a frame, a tow hitch mounted on the frame with the possibility of rotation of the cultivator, a hopper for seeds, a device for preparing the soil and distributing seeds, a packer roller, supporting wheels and a shorting. Disc working bodies are pivotally suspended from the frame, coupled by means of the articulated transverse rods. Disk working bodies and cultivators are spring-loaded (see ed. Certificate of the USSR No. 1722272 according to MKI A 01 B 49/06, claimed 14. 02. 90 g.).

Common disadvantages of the known combined units for tillage and sowing are the uneven distribution of seeds over the sowing area, the inability to use on various agricultural fields with or without stubble conservation, in areas requiring rotation when the unit is in working condition.

The utility model is based on the task of creating a combined unit for tillage and sowing, which has high reliability of technological operations and high quality tillage and sowing seeds.

The accomplished task is solved in that in a combined unit for tillage and sowing containing a frame, a towing device mounted on the frame with the possibility of rotation, a cultivator, a hopper for seeds, a device for preparing the soil and distributing seeds, a packer roller, support wheels and a shortener, according to of the utility model, the unit is equipped with a steam allogram mechanism and a leveling roller, and the cultivator, leveling and rolling rollers are mounted on a parallelogram mechanism mounted on the frame, and the device I soil preparation and distribution of seeds is in the form of disc coulters, the upper part of the pillars which are mounted on the frame for rotation. The cultivator is mounted on a bracket with holes for mounting bolts. The leveling roller is fixed on the lever with a spring adjustable in length; the Zagortach is made in the form of a chain loop, the links of which are equipped with longitudinal plates with curved rods-night pick-ups.

Figure 1 shows the proposed combined unit in the working position, side view; figure 2 is the same, a top view; Fig. 3 shows a link of a chain loop of a shorting, side view; in FIG. 4 shows a chain loop link, top view.

The combined unit comprises a frame 1, a towing device 2, supporting front wheels 3, a seed hopper 4, rotary disc coulters 5 and a cultivator 6, a leveling roller 7, a rolling roller 8, supporting rear wheels 9 and a grinder 10, a cultivator 6, the leveling roller 7 and the packer roller 8 are mounted on a parallelogram mechanism 11 mounted on the frame 1. The cultivator 6 is mounted on an arm 12, in which holes for fixing bolts are made. The leveling roller 7 is mounted on the suspension arm 12 with a spring adjustable in length 14. The shortener 10 is made in the form of a chain loop, the links of which are provided with longitudinal plates 15 with curved pointed rod-poles 16. The unit is equipped with an electronic drive metering system (not shown in the drawing). The packer roller 8 is equipped with a removable spiral made of strip metal and fixed to the surface along its entire length. This removable spiral (not shown in the drawing) is used when working on heavy soil.

Before starting aiperara, depending on the sowing crop, soil and technology used, the seeding rate, the depth of the disk coulters 5 and the cultivator b, the effort of applying the roller skating rink 8 are set, and the picker 10 is set to active or passive operation. The position of the cultivator 6 in the vertical plane is adjustable 5 by moving the bracket 12 having holes and iodine mounting bolts along the connection with the allelegging mechanism 11.

When the unit moves, the disk coulters 3 loosen the soil and the depth of seeding, undercut the vegetative soriacs and separate the semen coming from the vas deferens and the entire width of the disc coulters 5.

The cultivator b provides, depending on the adjustment, a very small or weak soil lump, mulching the surface with crop residues, and a rafting roller 7 ensures leveling the soil. A baking roller 8 compacts the soil and seeds. Zagortan 10 by means of soil rods fixed on the links of a chain plume 16 loosens the surface layer, cuts out 1 phezany weeds and additionally treats me.

The change in speed of the aiperaxa, as well as during turns, is not disturbed by the technical process of the unit, since the main working bodies carry out rotational movement, and this rotational data is carried out without drive. At the same time, the disc soshniki 5 are self-cleaning from the soil and pacTHTej & Hbix residues. In the proposed unit, electrochemical seeding control is carried out.

The proposed unit has high reliability of technological operations and high soil cultivation and seed sowing.

When the aggregate is used and when the seeder is in operation, the seeds are distributed evenly over the entire width of the seeding, the extended layer of soil in the seed zone is} in the 1st mulch and the surface prevents the seeds from peeling,

creating optimal conditions for plant growth and productive use of available moisture.
