Description

The invention relates to agriculture and can be used in mani plants for the treatment of cotton seeds.

A device for seed dressing, containing, its drum-type mixer c) is known. A screw working body inside it, the blade of which is divided into alternating sections of turns with a mutually opposite direction of the windings, and having at one end means for loading seed II chemical drug, and on the other - discharge window.

The disadvantage of such a device is the low degree of mixing of seeds and the loading of the latter in places where the auger blade is modified.

The purpose of the invention, the increase in agitation, is achieved by the fact that the coils of the sections are formed by sectors, and the coils of the sections, and the direction of which they promote the material to the discharge window, have a greater pitch than the opposite direction.

FIG. 1 is a diagram of the proposed device installed in a cotton seed picker in two projections and a section along A-A; in fig. 2 - the working body of the device, a longitudinal section (the blades are shown continuous) and a section along B - B.

The device for treating chloic seeds consists of a feeder 1 for iodine seeds and a nitrite 2 for a chemical preparation made in the form of bunkers, in the lower part of which there are gear metering devices, a mixing drum 3 made in the form of a cylindrical body with a screw body inside it 4, the blade of which is divided into alternating sections of coils 5 and 6 with taken n 0-protivopolozhnym direction of the windings and extracted from sectors 7, conveyor 8 to move the filled meps, the bunker 9 with d vacuum pipes and a general reversing valve for loading seeds into bags, cam mechanism 0 for wiping out the bags in the process of filling them, vent 11. torus 11 for suction of dusty air and zayapalnogo gaggle 12.

A device for seed dressing for chloe seeds works as follows.

When turning on the device, the seeds and the chemical preparation come from the feeders 1 and 2

In the mixing drum 3. At this, the distance from one step of the section of the turns 6 of the mixing drum 3 moves them forward, and on the next step, the sections of the turns 5 in the opposite direction. Prp this

the step toward the discharge side is larger than the step toward the opposite side, whereby the material moves in the radial direction, and in the longitudinal direction it moves back and forth from the inlet to the outlet. Next, the treated seeds enter the discharge bunker 9. The bags 4 are put on the branch pipes of the discharge bunker and secured with ties. In the process of filling, the bag is shaken from below with the help of a cam mechanism 10. The filled bags are removed from the nozzle and directed along the conveyor 8 to the sewing machine 12. Dusty air is sucked off by the fan P.

The proposed cotton seed dressing apparatus, if necessary, allows the seed, sowing seeds to be disinfected using dry, semi-dry and wet methods.

Subject invention

A device for dressing seeds, preferably cotton, containing its drum mixer with a screw working body located inside it, the blade of which is divided into alternate, carrying sections of coils with a mutually opposite direction of windings, and having one end

Means for loading the seeds and the chemical preparation, and on the other - an unloading window, characterized in that, in order to increase the intensification of non-mixing, the coils of the sections are formed by sectors, and the coils

sections, the direction of winding which contributes to the advancement of the material to the discharge window, have a larger step of winding than the opposite direction.
