Description

one

The invention relates to machines for wiping seeds of perennial grasses from the shells, flax seeds, etc.

A number of machines for wiping grass seed are known in agriculture. The terrestrial machine of these machines includes a fixed deck and a vrash, ayush, and a cylindrical drum, according to which it has corrugated whips. In other designs, the deck is a cylinder made of a metal woven mesh, inside of which the vrash, is similar to the drum described above with whips. Both in the first and in the second case, the decanter is fixed relative to the frame.

Also known is a clover with a rotating drum and a slowly rotating deck, the deck is made up of rings, and discs mounted on the shaft are inserted into the space between the rings of the decan. Thus, the deck is cleared after each revolution from sticking seeds. But because of the location of the long side of the holes perpendicular to the cylinder-forming elements, the degree of wiping is significantly reduced.

In addition, the quality of work is reduced, as with such a constructive solution, part of the raw material from the grater apparatus is carried out by an exhauster.

A significant disadvantage of all clover grooves is that the wiping of the seeds takes place approximately in 1 / 4-1 / 3 square of the fixed deck in its lower part. Such irrational use of deck space

leads to the fact that these kleverterki have large sizes, considerable weight and require a greater expenditure of power.

In order to effectively use a grating surface, increase the throughput

abilities and simplification of the design in the proposed clover-eater pests are rigidly fixed on the clover-cover.

To create an aerodynamic effect for the suction and discharge of the treated

The material in the proposed clover mortar, the rotating cylindrical deck is provided with longitudinal holes and has an external surface of the blade. In order to intensify the process, wiped out and more evenly distribute the sucked material over the surface of the decan, on one shaft with the deck, inside the deck, the extractor impeller is mounted.

Exhauster located inside the deck

allows terkn work with self-loading. Alacca is drawn in through a flexible hose attached to the outlet neck with a nozzle.

FIG. 1 shows the proposed kleveroterka with axial feed, longitudinal section

in fig. 2 - the same, a cross-section along the impeller of the exhauster.

An axial flow clover includes a sump load hose 1 and a receiving neck 2. Inside the housing 3, a rotating deck 5 and an extractor impeller 6 are fixed to the shaft 4. The deck drum has an impeller 10 with exit windows at the outlet. On the outer surface of the deck there are blades 11.

Clovertherka works in the following way.

When the shaft rotates, the impeller of the exhauster, rigidly connected to it, creates in the inlet throat and pneumatic loading hose a suction air flow, which trasses and digs into the grater apparatus of the machine. When the pyzhiiy enter the grater apparatus, the rapidly rotating blades of the exhauster drop it onto the rotating deck. By the centrifugal force of the pump, it is pressed against the deck and passes through the gap between the deck and the whips. The gap between the deck and the whip is adjusted by turning the taper axis, to which the whip is welded to the lever arm. The wiped seeds and wads are pushed through the deck grooves by an air stream and pentroplastic force, and large particles, passed through the entire length of the deck, pass through the windows of the impeller.

The output air flow created by the exhauster and impeller transports the processed pyzhin through a pipeline into a cyclone, where the seeds of clover under the action of centrifugal forces settle in the bunker at the bottom of the cyclone. From here, the mass is discharged into bags for transportation to the final cleaning.
