Description

The invention relates to agricultural displaced by one third

productive engineering and can be used for threshing and grinding of corn in the laboratory. five

The purpose of the invention is to improve the quality of threshing cobs with high humidity, increased productivity and reduced labor costs.

FIG. 1 shows a diagram of a laboratory threshing grinder for corn, a longitudinal section; 2, the same top view; fig.Z - the same, side view; 4 is a diagram of a drum thresher; figure 5 - gravity-, 5 ration cassette, side view; Fig.6to same, top view.

The laboratory thresher mill contains a bed 1, on which a mill mill 2, a drum thresher 3, a milling grinder 4 stalks, a front threshing device 5 and a drive 6 are mounted. All mechanisms are located on the common hollow shaft 7, which is mounted on the sub. wild roses 8.

The burr thresher contains millstones 9 encased in casing 10 and inlet hopper 11.

The drum thresher 3 contains a threshing drum 12 with rubber-coated 30 scourges 13, rubberized deck 14 and a feeding device 15. This device consists of a removable gravity cassette 16 with a time relay (not shown) and with flaps .17 35

and 18, which are connected pivotally with the snag • chag 19, connected in its lower part with the valve 20 of deck 14, and at the upper with the pneumatic cylinder 21, which has valves 22 and 23. 40

milling grinder 4 contains a set of milling discs 24, installed, casing 25 and the feeding mechanism 26, the design of which is similar to the feeding device 15.

The face threshing device 5 contains a three-cam mechanism 27 with rubberized cams 28, a chute 29 for removing the grain, a reflecting chamber 30, a grain guide 31, a nonius 32 for setting the cams 28 and a feed mechanism 33.

The mechanism 33 consists of a gravity cassette 34, similar to the cassette 16. In addition, the feed mechanism 33 has a guide chamber 35, a shutter 36 with a handle 37, a telescopic rod 38 with a cylinder 39 and three links of spring arms 40. The last link of the arms 40 has latches 41 to keep the cob during threshing .. Its working arms of these levers have elastic rubberized lining 42, made with reefs.

The actuator 6 consists of a pulley 43, belts 44 and an electric motor (not shown).

Threshing mill works as follows.

Corn cobs from cassette 34 fall into chamber 35, and then into cylinder 39. Then, with rod 38, the cob is guided to spring arms 40, which hold it and feed it to cams 28, where the threshing of grain is carried out.

The threshing mill can provide simultaneous operation of the drum thresher 3, the milling grinder 4 and the face threshing device 5, as well as their separate work.
