Description

[Detailed description of the invention] Industrial applications The present invention relates to a sorting device for a threshing machine.

Conventional technology In the past, a swinging sorting shelf was installed in which the grains were threshed in a threshing room, and the grains were sorted while being shaken and transferred. A number receiving gutter and a second receiving gutter for receiving the second grain are provided, and the grains leaking from the swing sorting shelf and leaking onto the surface of the first grain shelf on the most receiver side are collected from the first grain receiving gutter. The grains that were supplied to the second receiving gutter and leaked onto the second stream grain shelf surface on the second receiving gutter were the sorting device that was supplied to the second receiving gutter.

Problems to be Solved by the Invention The husk supplied into the threshing chamber is threshed while being transported within the threshing chamber, and the threshed grains and straw waste generated during the threshing process are separated from the threshing net. The straw waste is supplied to a swinging sorting shelf that swings from the straw waste outlet, and is separated into grains and straw waste on this swinging sorting shelf during swinging transportation, and the separated and sorted grains are separated and sorted by the swinging shaker. It leaks from the sorting shelf and is screened while falling through the sorting air channel, falls onto the surface of the first grain shelf, flows down the surface of the first grain shelf, and is supplied into the first receiving trough. The grains are transferred and discharged from the inside of this first receiving gutter into the grain lifting device, are fried in this grain lifting device and are discharged outside the machine, and also fall from the end of the swinging sorting shelf.
The grains fall onto the second grain shelf, flow down the second grain shelf, and are supplied into the second grain machine.

The grain is transferred and discharged from the second receiving trough into the second reducing device, returned to the threshing chamber by the second reducing device, and processed again in the threshing chamber.

In a threshing machine in which the separated and sorted straw waste is sucked in by a suction dust extractor and discharged outside the machine, if a large amount of straw waste is generated during the threshing process, the grains that are being oscillated and transferred on the oscillating sorting shelf are However, it becomes difficult for the grains to fall from this swinging sorting shelf, so that the grains are oscillatedly transferred to the end of the swinging sorting shelf and fall from this end. Since the grain is returned to the threshing chamber by the reducing device, the grains may be damaged frequently, and if the amount of second reduction is large, the processing capacity of the husk in the threshing chamber may be reduced.

Means for Solving the Problems This invention provides a sorting air passage integrated at the end of a swinging sorting shelf (2) that receives threshed grains in a threshing room (1) and sorts them while swinging and transporting them. (3) Located on the boundary between the first receiving gutter (4) that receives the first item on the lower side and the second receiving gutter (5) that receives the second item, this first receiving gutter (4) side The guide plate (7) slopes downward toward the surface of the first grain shelf (6) and slides into contact with the surface of the first grain shelf (6). The sorting device for a threshing machine is configured with an elastic body (8) that closes the gap between the grain and the surface.

Effect of the invention The husk fed into the threshing room (1) is
The threshed grains and the straw waste generated during the threshing process are separated from each other by a swinging sorting shelf (2
) and are separated into grains and straw waste on this swinging sorting shelf (2) during swinging transfer, and the separated grains leak from the swinging sorting shelf (2). While falling through the sorting air passage (3), the grains are selected by the wind, fall onto the first flow shelf (6), flow down the first flow shelf (6), and enter the first receiving gutter ( 4) The grains that are fed into the machine and discharged from the machine through the first receiving gutter (4) by the grain lifting device and fall from the end of the swinging sorting shelf (2) are placed on the upper surface of the guide plate (7). from the upper surface of this guide plate (7) and flow down the surface of the first grain shelf (6) to the first receiving gutter (4).
), and is discharged to the outside of the machine via the first receiving trough (4) by the grain lifting device.

The grains and grains with branches attached that fall from the end of the swing sorting shelf (2) over the guide plate (7) are supplied into the second receiving gutter (5), and the second receiving gutter (5) After that, it is returned to the threshing room (1) in the second reducing device and processed again.

The separated and sorted straw waste is sucked up by a vacuum cleaner and discharged outside the machine.

Effects of the Invention According to this invention, there is a
Sorting air passage (3) Lower first gutter (4) and second gutter (5)
A guide plate (
7), and an elastic body (8) is provided on the guide plate (7) to slide into contact with the surface of the first grain shelf (6) and close the gap with the surface of the first grain shelf (6). Due to this, the swing sorting shelf (2)
By receiving the grains falling from the terminal end with the guide plate (7), the amount of secondary reduction is reduced, so damage to the grains is reduced, and at the same time, the processing capacity of the husk in the threshing room (1) is increased. The guide plate (7) and the first grain shelf (6) do not lower.
Since the gap with the surface is closed by the elastic body (8), the sorting air passing through the upper surface of the guide plate (7) does not decrease, so good grain sorting performance is always obtained. be able to.
