Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to machines for treating seeds with chemical chemicals. The purpose of the invention is to improve the quality of the hydraulics, vanilla and reduce the size. The treater contains a centrifuge (C) 7, enclosed in the casing 8 and having a section 2 of the screw. C is installed on the output end of the housing 6 of the auger with the possibility of its rotation in the direction of turning, section 1 and 2 of the screws. The frequency of rotation C is greater than the frequency of rotation of the screw sections, the turns of the blades of which are made in opposite directions. The cavity of the casing 8 and the housing 6 are interconnected. Section 2 of the auger can be double-threaded. In the cavity of the discharge of seeds, C 7 is installed their resetter. Section 1 of the auger grips the seeds and moves them to C 7, while the seeds are moistened with chemicals. When rotating C with a higher frequency, but in the same direction with section 2 of the screw, the seeds are pressed to the surface of C by the action of centrifugal forces; they run onto the blades of the screw. The latter moves bx towards the unloading window, where the diverter pushes them into the container. Excess pre-chemicals are supplied from the cavity of the housing 8 to the cavity of the screw body 6 for reuse. 3 hp f-ly, 2 ill. with "(L with 00 O5 about vj th

FIELD: agriculture.

computer-aided engineering, in particular for machines and aggregates for the treatment of seeds with chemical chemicals.

The purpose of the invention is to increase the quality of seed dressing and reduce the size of the dressing agent.

Figure 1 shows a seed treater, a section of the body and a centrifuge along the axis; figure 2 - section-LA in figure 1.

The seed treater contains a transporting working body in the form of a sectional section containing sections and 2 augers mounted obliquely, a seed bin 3 with a flap 4 mounted above the lower end of the auger section 1, and a tank 5 for the suspension of chemical chemicals. In addition, a centrifuge 7 is mounted on the housing 6 of the screw section 1, enclosed in the housing 8, and on the shaft rigidly in the form of a pipe 9 section is placed a screw section 2, the turns of which are made in the opposite direction of the screw section 1 of the screw and mounted between the supports with gap.

In order to increase the uniformity of loading of the centrifuge, the screw section 2 can be made two-way. Rotation of sections 1 and 2 of the screw and centrifuge of one direction with a difference in the increased frequency of rotation of the centrifuge. Sections Г and 2 augers receive rotation from the electric drive 10, and the centrifuge from the electric drive П via shaft 12 and hub 13 with windows 14. The hub separates the centrifuge to the seed discharge cavity of the excess chemicals in the casing 8 and the seed discharge cavity 15 . The cavity of the housing 8 by the tubes 16 communicates with the cavity in which the screw is located. From the end face, the cavity 15 of the centrifuge is closed with a fixed claw 17, on which is installed a nozzle 18 and a resetter 19 seeds. The shaft of the screw section 1 is mounted on the supports 20 and 21, and in the support 21 windows 22 are provided for the passage of seeds into the centrifuge cavity. In addition, the treater is equipped with a device for maintaining a given level of chemical chemicals in the body of the working body (not shown).

The seed treater works as follows.

The screw body 6 is filled to a predetermined level with chemical chemicals that open

The flap 4 is turned on and the actuators 10 and 11 are turned on. Seeds from the hopper enter the zone of the auger 1 filled with dohimicates, moistened with a rotating auger, agitated, and finally covered with dohimicates all over the surface. Moving along the axis of the organ through the windows 22 in the support, it is fed into the cavity of the centrifuge 7.

Since the centrifuge 7 rotates at a lower frequency, but in one direction with section 2 of the screw, the turns of which are made in the direction opposite to the turns of section I of the screw, the seeds are driven by centrifugal forces, pressed against the inner surface of the centrifuge 7 and raid the blade of section 2 of the screw, moving along the axis at a speed depending on the frequency of rotation of section 2 of the screw and the centrifuge 7. Moreover, moving along the axis by the pitch of the screw, the seeds will be able to complete several revolutions with the centrifuge, which ensures that the excess x dohimikatov with seed and executing centrifuge reduced dimensions, i.e. the design ensures the discharge of excess dohimicates from the seeds even with a slight axial dimensions of the centrifuge and section 2 of the screw.

The surplus of pre-chemicals under the action of centrifugal forces through the perforations of the centrifuge is dropped from the seeds into the cavity of the casing 8, and from there, through the tubes 16, they flow into the cavity of the housing 6.

Freed from unnecessary pre-chemicals, the seeds through the window 14 enter the cavity 15 and, pressing (by centrifugal forces) to its inner surface, rotate with the centrifuge. The ejector 19, installed in the cavity, removes the seeds from its surface and they flow down the pipe 18 into the bagcota, i.e. unloading of the centrifuge takes place without stopping it.
