Description

one

FIELD OF THE INVENTION The invention relates to agricultural machinery, namely, devices for threshing grain crops.

Known threshing and separating device containing a pair of take-up rollers and face-mounted thresher rollers installed in pairs 1.

The disadvantages of such a device are the high injury of threshed grain and the low degree of release of the grain fraction.

The purpose of the invention is to increase the productivity of the threshing-separating device and reduce the injuries of grain.

This is achieved in that the pairs of receiving and threshing rollers are installed vertically, with at least two pairs of threshing viltsa connected in a block, the surfaces of which are provided with a screw cap, located on the middle pair parts, and on the next pair of threshering rollers, the shnekov winding is made at their ends. In addition, shnekovka can be made removable.

Such an embodiment of the device provides a high yield of damage to the injuredness of the grain, and the threshing mass is evenly distributed throughout the device due to the use of auger winding, and prevents the rollers from winding. Plant stems retracted from sidewalls.

FIG. 1 shows a threshing and septic dispenser; in fig. 2 is the same, section A-A in FIG. one.

The threshing and separating device contains feeds I, 2 and threshing 3, 4 blocks. The feed units are a pair of round rubberized and spring-loaded rollers 5, and the threshing - four faceted rollers 6, connected in blocks. Sektsy1 iBHTkoB 7, 8 and 9 shneke are fixed on the surface of the faceted rollers. The middle sections of turns 8 and 9 are designed to distribute the mass along the length of the threshing rollers 6, and the outer sections 7 serve to divert the stems from the sidewalls 10.

The threshing and separating device may be used both in stationary installations and in combine harvesters.

When using a threshing and separating device on combine harvesters when selecting rolls, or when harvesting by direct combining, the bread mass from the header with the help of an inclined conveyor of the receiving chamber of the combine harvester is fed into the inter-mill space of the threshing device. The mass is captured by the feed rollers 5, compressed between them and guided into the threshing space of the rollers 6. The left and right sections of the turns 8 and 9 of the rollers 6 distribute the mass up and down along the rollers. As the stems exit the threshing rollers, they are captured by the powering threshing rollers of the feeding unit, and then sent to the threshing space of the rollers 6 of the block 4 Further distribution of the stems along the length of the rollers 6 occurs the same way. Distributed layer of stems most fully threshing chivayets rollers b. The rollers b, acting with their faces and ribs, produce an intense stem of the stems and separate the grain to the left and to the right without hindrance and damage. Grain immediately goes to clean. The sections of turns 8 and 9 of the auger of the rollers b rotate the stems and pull them along the rollers. Turning the stems allows them to be threshed with faceted rollers on all sides. The grabbing of the layer of stems by sections of turns 8 and 9 along the rollers allows to release the grain from the middle part of the straw layer and to produce its selection.

Due to the sequential alternation of feed and thrashing blocks and located on the threshing rollers of the removable screw winding, the productivity of the device is reduced, the injuryability of the grain is reduced and its shortage is sharply reduced.

Claims (2)
