Abstract

FIELD: agriculture; machine building.

SUBSTANCE: pneumatic seeding apparatus for combined sowing comprises a seed hopper divided by a partition, a sowing disk with penetrated conical cells vertically installed on an axis, an air nozzle and a planting runner. Hopper is divided by two removable partitions. Sowing disk and the planting runner are made equal in width and consist of 3 parts fixed together with the ability of their shift. Parts of the seeding disk are fixed with a pressure plug. Parts of the planting runner are fixed with bolts. Shift value ratio of the planting runner parts is determined as 1:2:4.

EFFECT: invention provides expansion of the apparatus operational capabilities.

Description

The invention relates to the field of agriculture, namely to combined crops of various crops.

Known seeding apparatus of nesting sowing, providing regulation of the seeding rate using a hub with interchangeable sector plates (USSR Author's Certificate, 545280 IPC A01C 7/04, 1975).

A disadvantage of the known sowing apparatus is its high sensitivity to the dimensional characteristics of seeds and the acquisition of a large number of interchangeable sector plates.

The closest in technical essence to the claimed device is a pneumatic sowing device selected as a prototype, including a seed hopper, a vertically located sowing disk with through conical cells placed with a uniform pitch, and an air nozzle to remove excess seed from the conical cell (CCCP copyright certificate , 1192667, IPC A01C 7/04, 1985).

A disadvantage of the known device is the lack of the possibility of combined sowing of seeds of three crops at the same time, as well as the need to complete interchangeable sowing disks to ensure different sowing rates, the device operates using a chain transmission from two sides.

An object of the invention is to expand the operational capabilities of the sowing apparatus through the use of composite disc and opener for sowing seeds of various crops using one stellar pair.

The technical task is achieved in that the pneumatic sowing device for combined sowing, including a seed hopper separated by a partition, a vertically mounted sowing disk with through conical cells, an air nozzle and a coulter, according to the invention, the hopper is divided by two removable baffles, a sowing disk and a skid the coulter is made equal in width and composed of 3 parts, which are fixed to each other with the possibility of their displacement, the sowing disk - with a clamping sleeve, and the skid prominent coulter - bolts, the ratio of the displacement magnitude opener portions defined by the condition of 1: 2: 4.

The invention is illustrated by drawings.

In FIG. 1 shows a pneumatic metering device for combined sowing, side view; in FIG. 2 - the same, section aa.

The pneumatic sowing device for combined sowing contains a seed hopper 1, separated by partitions 2, vertically mounted on the axis 3, a composite sowing disk 4 with a clamping sleeve 5 and through conical cells 6, an air nozzle 7, side covers 8 and a composite coulter 9, the width equal to the width of the sowing disk 4. The opener 9 is made three-level.

Pneumatic metering device for combined sowing works as follows.

Before work, the sowing disk 4 and the coulter 9 are adjusted, the parts of the sowing disk 4 are displaced according to a predetermined pattern and pressed together by a pressure sleeve, and the parts of the coulter 9 are placed at different seed placement depths in a ratio of 1: 2: 4 and fixed with bolts.

Seeds from the hopper 1, divided by partitions 2 into three parts, fall into the conical cells 5 of the sowing disk 4 rotating on the axis 3. When passing under the nozzle 7 with air flowing out from it, excess seeds are blown out of the cells 6, and one lower seed is pressed by the air flow to smaller base of the cone of the cell 6 and is transported through the coulter 9 into the furrow.

Seeds located in cells 6, for example, three parts of the sowing disk 4, are moved to the corresponding parts of the opener 9, from where they fall into the open furrow at different depths.

The seeding rate is regulated by the presence of the number of parts of the sowing disk 4 and the corresponding parts of the coulter 9.

The sowing discs 4 are equipped with a clamping sleeve 5, which allows them to be displaced without removing the parts of the disk by loosening and tightening the nut, and the parts of the coulter are bolted together with the possibility of vertical displacement.

Using the proposed apparatus will allow to expand the operational capabilities of the sowing apparatus through the use of a composite disk for sowing seeds of various crops and the use of one stellar pair.
