Description

(54) PNEUMATIC SEALER

I

The invention relates to agricultural machinery engineering, in particular, to sowing machines intended for planting vegetable and other crops, mainly for seedlings in protected ground.

Known pneumatic forgings, which has supporting-pressing and furrow-forming elements, vacuum seeding drum with rows of holes and a bunker for cutting.

Also known is the spreader, comprising a frame with compacting rollers and furrow forming elements, a drive, a seed bin and a vacuum seed drum with rows of holes 2,

However, for sowing various crops whose seeds vary in size, and also to change the sowing pattern, it is necessary to replace the sowing drum.

The purpose of the invention is the expansion of technological capabilities of pneumatic seki.

This goal is achieved by the fact that in a pneumatic splitter, including a frame with sealing rollers and furrow forming elements, a drive, a seed hopper and a vacuum seeding drum. with rows of rollers, the compacting rollers are equipped with wedge-shaped rings, and the sowing drum is equipped with elastic inlinic rings, and the holes in the center of the exhaust drum are made

10 with different diameters.

FIG. I depicts the scheme of the proposed crop, general view; in fig. 2 compacting roller with hazardous bodies; in fig. 3 shows the fastening of the furrow 15 of the bearer to the compacting roller-cut section A-A in FIG. 2; in fig. 4 - seeding drum; in fig. 5 is a section BB in FIG. four.

The plant consists of a frame 1, a flake of ceL20 s on a compacting roller 2 with furrowing elements in the form of wedge-shaped rings 3, a drive 4, a hopper for seeds 5, a vacuum seeding drum 6, on

which, with a pitch equal to the width between the seeding array, are made up of rows of holes 7, 8 and 9 with different diameters and cylindrical elastic rings Y are installed. A compacting roller 2 is connected to the actuator 4 and the sowing drum 6 chain drives. Selka also has a roll-in roller 11.

Selka works as follows.

The roller 2 from the actuator 4 receives rotation and moves the seed roller, at the same time it compresses the soil, while the furrowing elements 3 cut the macroelectric. The vacuum seed drum 6 picks up seeds from the seed bin 5 by suction holes 7 - (8 or 9) and transfers them to the planting zone, where, as a result of vacuum shielding, they are dropped into the grooves, and the rolling roller 11, destroying the ridges of the grooves, embeds the seeds into the soil. The adjustment of the seed for sowing seeds of various sizes is made by shifting the cylindrical rings 10 to the corresponding holes (7, 8 and 9), while the wedge-shaped rings 3 on the compacting roller 2 are moved in a similar way.

The use of the proposed pneumatic seed provides lowering costs and expanding technological capabilities due to the elimination of replaceable drums and more simple reconfiguration of seed to different cultures.

Formula iebre.teni

Pneumatic seeds, including a compact with sealing rollers and furrow forming elements, a drive, a seed bin and a vacuum sowing drum with rows of holes, characterized in that, in order to expand technological capabilities, the compacting rollers are equipped with a wedge-shaped rings, and the sowing drum - elastic cylindrical rings, with openings in the rows of the seeding drum made with different diameters.
