Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a threshing device and can be used in combine harvesters and the like.

Problems to be Solved by the Invention In this method, the culm of the threshing method and the threshed straw waste in the threshing chamber are discharged from the straw opening at the end of the transfer of the threshed husk culm in the threshing chamber. Due to mixing and entanglement of debris, etc., it is not possible to discharge the straw debris smoothly, which also affects the sorting action of the swinging sorting device that receives and shakes the straw debris discharged from the straw outlet.

Means for Solving the Problem The present invention provides a threshing room (2) in which grains are threshed by the rotation of a handling drum (2) while the culm transfer device (1) pinches and transports the side part of the stock head.
3) is located above the swinging sorting device (5) which receives the threshed grains in the threshing room (3) and sorts them while swinging and transporting the grains. The threshing device is provided with a scraping cylinder (6) that rotates to scrape out straw waste and threshed transfer culms discharged from the straw opening (4) part.

Functions and Effects of the Invention Grain culms that are transferred by supplying the stock root part to the husk culm transfer device (1) supply the ear part to the threshing chamber (3) and perform threshing action by rotating the handling drum (2). Most of the grains leak out from this threshing room (3) and are subjected to the sorting action by the swing sorting device (5) below, but the threshing room (3) containing a large amount of straw waste, etc.
) is discharged from the straw removal port (4) together with the threshing culm by the transfer device (1), and the removal culm is removed by a scraping drum (4) that rotates outside the straw removal port (4). While the straw is being scraped out by the straw removal port (4), the straw debris adhering to the culm body part of the straw is shaken off and discharged to the upper rear side.
), the scraps, etc. are also scraped out and dropped onto the lower swinging sorter (5), and the grains, twig stalks, etc. containing these scraps are scraped out by this swinging sorter (5). As it receives a swinging sorting action, the stagnation of straw waste in the threshing room (3) is reduced, and the flow of threshed grains from the straw opening (4) to the swinging sorting device (5) is made uniform. A smooth sorting action can be performed, and the number of culms, etc., can be reduced.

Example The threshing room (3) is provided with a threshing net (7) on the lower surface, a handling cylinder (2) is provided inside so as to be rotatable about a longitudinal axis (8), and a supply port (9) for supplying husk is provided on the front side. ) is provided, and a draining port (4) is opened at the lower part of the rear side, and the stock base of the culm is held between these two ports (9) (4) along the negative side of the threshing chamber (3). The transfer device (2) for transferring is composed of a lower transfer cheno α0 and an upper clamping rod θη, and the scraping cylinder (6) is moved in the y-culm direction on the rear side of this evacuation port (4). The scraper cylinder (6) is provided to be rotated along the direction along the axis α, and scraper teeth are provided on the outer circumferential surface of the scraper cylinder (6). Cao uses this scraping drum (6
) is a cover that covers the upper side of the (141 Hato's scraping cylinder (
This is a culm discharge device installed from the upper part of the culm toward the rear tip of the culm (6), which takes over the culm transferred by the transfer device (1) and discharges it. (l$ is a suction dust remover located behind the scraping cylinder (6).

The oscillating sorting device (5) has these threshing chambers (3) and scraping drums (
A sorting shelf αQ, which is located in the sorting room below the threshing net (7) and the straw removal port (4), is located below the threshing net (7) and the straw removal port (4), and the sorting shelf αQ, whose upper surface is formed into a rack shape, is placed under the threshing net (7) and the straw removal port (4), and suction is carried out from the rear side of the sorting shelf αQ. Dust extractor 0Q
A straw rack (lη) is provided under the sorting shelf αQ, and a sorting net α is provided below the sorting shelf αQ. Such a swinging sorting device (5) is designed to swing in the front and back direction. 09 is a sorting air passage, the front end of which communicates with the pressure winnowing machine (1), the rear end of which communicates with the suction dust extractor 0Q through the rear end of the oscillating sorting device (5), On the lower side, the first receiving gutter Qυ, the second receiving gutter (A), etc. are installed. (C) is the second grain lifting machine, and the second receiving gutter (A) and the threshing room (3) are installed. It communicates with the second reduction chamber (b) at the rear end of the cylinder.

The husk is fed into the threshing room (3) from the supply port (9) while the stock head is held by the transfer device (1).
Most of the grain is threshed by the rotation of the threshing net (7)
It leaks directly from the oscillating sorting device (5), falls onto the sorting shelf (6), undergoes oscillating sorting, and is further subjected to sorting action in the zero barrel section of the lower sorting net, and is then filtered through the sorting air path. It is wind-selected by a samurai and sorted into the first receiving gutter (2), the second receiving gutter (a), etc., but the straw waste is processed in the threshing room (3) along with the threshing culm. The straw waste, grains, etc. are scraped out from the straw opening (4) by the rotation of the scraping cylinder (6), and are dropped onto the rear end of the sorting shelf αQ of the swing sorting device (5) below. Since the waste culm is transferred from the terminal end of the transfer device (1) to the waste culm device α→, during this time, the tip of the tip is shaken by the rotation of the scraping cylinder (6) and is kept free of grains. The straw waste is transported to the rear, and is transferred onto the straw rank 0η, where it is shaken and sorted, and either suctioned or discharged by the suction dust remover α, or directly transferred and discharged from the discharge port.
