Description

The invention relates to agricultural machinery, in particular to tilting chambers of combine harvesters, and can be used in machines for harvesting maize for grain. The inclined chamber of a corn-harvesting combine is known, which contains a cornus, on the bottom of which there are horizons; 1 tines 1. The inclined chamber closest to the invention is contained, and the sides, the bottom with the ribs and the conveyor 2 located above them. A disadvantage of the known inclined chambers is the large grain losses due to the feeding of the cobs unoriented by these chambers to the thresher of the combine. It is well known that the quality of threshing of cobs by the threshing drum depends on the position of the cobs relative to the axis of the drum turning at the moment they enter the mine, 1. Studies have found that if the cobs are oriented parallel to the axis of the threshing drum, then optimal conditions are created for their threshing. At the same time, the cobs run around the drum, advancing in the gap between the drum and the deck as the cobs advance to the exit of the thresher. The grains are squeezed out of the cob rods without damage. As a matter of fact, the rods, after being separated from the grain, are fed to the straw walker with the whole, in the absence of under-ground. The quality of grain cleaning in the bunker corresponds to the technical requirements of 1P1 m. In case the cobs enter the milk tank are redirected, i.e. perpendicular to the axis of rotation of the drum or at an angle to it, there is a destruction of the cob into separate parts that are harder to thresh. The rods shattered into smaller fractions fall through the rods of the deck, get into the network of the combine cleaning system and clog the regnet cells, which leads to poor grain cleaning and the need for frequent cleaning of sieves from the particles of rods stuck in their cells. The more the rods of cobs are destroyed in the threshing process, the harder it is to separate the grain on the cleaning sieves, and, consequently, to a greater extent, the grain is lost when entering parts of the heap into the stacker. A certain percentage of the parts of the cob of the cobs with unallocated grain is thrown out of the drum by the straw walker, increasing the grain loss due to the undersize. Those particles of rods that fall through the cells of the cleaning sieves clog up a heap of grain in the bunker, and therefore the cost of refining the grain by TOKV increases. The purpose of the invention is to reduce losses by targeting cobs to the threshing combine. This goal is achieved by the fact that in the device the conveyor is made in the form of sequentially mounted rotating tines, and the ribs are arranged parallel to the axis of rotation of the tines. In this case, the edges are placed between each pair of beaters. FIG. 1 shows a tilted chamber of a corn harvester, side view; in fig. 2 shows section A-A in FIG. 1. The inclined chamber comprises a housing 1 with a bottom 2, sidewalls 3 and a series of successively installed tines 4-7 with blades 8. The bottom is made with fins 9 arranged parallel to the swing axis of the tines. The ribs protrude upwards relative to the bottom and are located between each pair of beaters 4-7 and parallel to them. The tilted camera works as follows. Beaters 4-7, interacting with the bottom 2, move the cobs to the threshing machine of the combine. In the process of advancing along the bottom 2, that part of the cobs, which is located at this angle or parallel to the direction of their movement, meets in its way the ribs 9, turns and takes a position parallel to the axis of rotation of the drum, i.e., the cobs are oriented into the thresher. This creates conditions for high-quality threshing of the cobs with a combine threshing machine, reducing grain losses, increasing the purity of the heap of grain in the bunker, which, in turn, reduces the cost of additional cleaning of grain for the current. In order to simplify the construction, reduce its weight, the ribs can be made in the form of vyshtampovok in the bottom of the inclined chamber. Ribs are located between each pair of beaters. When this happens, the cobs are also forcedly oriented by the tine blades, when one end of the cob rests on the edge, and the opposite end of the cob, under the influence of the blade, turns parallel to the edge. For this purpose, the ribs are located between the beaters. The height of the ribs above the bottom does not exceed half of the maximum possible diameter of the cobs of harvested corn, which guarantees unimpeded movement of the cobs along the bottom, as well as cases of laying grain extracted from the cobs under the influence of beaters. The application of the invention will allow to reduce grain losses due to the implementation of oriented feeding of the ears to the threshing machine of the combine.
