Description

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

Conventional technologyIn the past, 4i! The left and right side plates of the swinging sorting shelf that sorts while moving are moved downward, and the gap formed between the outside of the left and right side plates and the left and right side walls of the machine frame on the lower side of the swinging sorting shelf. This was a swinging sorting device equipped with a guide mechanism that supported and guided the swinging of the swinging sorting shelf.

Problems to be Solved by the Invention The husk is threshed while being transported inside the threshing chamber, and the threshed grains and some of the straw waste generated during the threshing process are stored in the lower part of the threshing chamber. The leakage is supplied from the leakage net onto the swinging sorting shelf, which shakes it and separates it into grains and straw waste.The sorted grains are leaked from the swinging sorting shelf. The grains are sorted into the lower part of the machine, and the sorted grains are transferred to the - side and discharged out of the machine by the grain lifting device.

In addition, the sorted straw waste and the straw waste discharged from the threshing chamber into the dust suction device are discharged outside the machine by the dust suction device. The mechanism is located at a portion that protrudes downward from the left and right side plates of the swing sorting shelf, and is located at a space formed between the outside of the left and right side plates and the left and right side walls of the machine frame on the lower side of the swing sorting shelf. Because of this provision, the guide mechanism cannot be installed unless the total width of the swinging sorting shelf is significantly narrower than the total width between the left and right side walls of the machine frame, so the overall width of the swinging sorting shelf is narrow. When the threshing efficiency is improved, the amount of grain and straw waste fed onto this swinging sorting shelf increases, and therefore the layer of grains and straw waste on this swinging sorting shelf becomes thicker. This sometimes made it impossible to reliably separate grains from straw waste.

Means for Solving the Problems The present invention provides a swinging sorting shelf (1) for sorting grains while swinging and transporting the grains. Support arms (3), (3) are provided below the sorting shelf (1) portion and extend inwardly, and a gap is formed between the support arms (3) and the outer machine frame side wall (4). (5) is a guide mechanism (6) that supports and guides the swinging of this swinging sorting shelf (1).
) is the configuration of a swinging sorting device such as a de-a machine.

Effect of the Invention Grain is threshed while being transported inside the threshing chamber, and the threshed grains and some of the straw waste generated during the threshing process leak through the leakage net at the bottom of the threshing chamber. , is supplied onto the swinging sorting shelf (1), and the left and right side plates (2) of this swinging sorting shelf (1),
(2) At the lower end of the swing sorting shelf (1), support arms (3) that protrude inward from the bottom of the swing sorting shelf (1) are provided to control the swinging of the swing sorting shelf (1). The oscillating sorting shelf (1), which is oscillated by a supporting and guiding guide mechanism (6) and a oscillating mechanism, is oscillatingly transferred and sorted into grains and straw waste. The grains are air-sorted from the dynamic sorting shelf (1) during leakage, and the air-sorted grains are transferred to one side and discharged out of the machine by a grain lifting device.

The sorted straw waste and the straw waste discharged from the threshing chamber into the dust suction device are discharged to the outside of the machine by the dust suction device.

Effects of the Invention According to the present invention, the support arms (3), (3) to which the guide mechanism (6) for supporting and guiding the swinging of the swinging sorting shelf (1) is mounted, are attached to the left and right side plates of the swinging sorting shelf (1). (2), (2) is provided at the lower end of the swinging sorting shelf (1) so as to protrude inwardly under the swing sorting shelf (1), so that the support arm (3) outside and the machine frame side wall (4) )
The gap (5) formed between the The left and right side plates (2) of (1) no longer protrude outward from the left and right side plates (2) of (2), and therefore the left and right side plates (2) of this swing sorting shelf (1)
) and (2) can be placed close to the left and right side walls of the machine frame (4), the total width of the swing sorting shelf (1) becomes wider, and even when the threshing efficiency is improved. The history of grains and straw waste leaked to this swinging sorting shelf (1) becomes thinner, and as a result, grains and straw waste can be separated and sorted reliably, resulting in good grain sorting.
