Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for scraping out processed material in a threshing machine.

[Prior art]

In general, a threshing machine has a dust outlet connected to a swinging sorting shelf below at a receiving screen corresponding to the end of the handling barrel installed in the handling room, that is, an opening for dropping the processed material on the receiving side (inside the handling room). has been established.

[Problem that the invention seeks to solve]

Therefore, relatively large waste (such as dumpling-shaped culm cuts) generated when the amount of processed material in the handling room is large or when the processed material is wet will fall downward from the dust outlet of the receiving net. There is a problem in that the processing materials are carried around by the rotation of the handling cylinder without any processing, and eventually the waste gets clogged and stagnates at the dust exhaust port, causing an overload on the handling cylinder and preventing the threshing 1 sorting process from being carried out smoothly. Ta.

This invention aims to solve the above problems.

[Means for solving problems]

For this reason, the present invention has taken the following technical measures. That is, by approaching the dust outlet 3 of the receiving net 2 provided near the end of the handling cylinder 1, the processed material carried around at the end of the handling cylinder 1 is forcibly moved onto the swinging sorting shelf 4 below. A device for scraping out processed material in a threshing machine is provided with a scraping body 5 for scraping out.

〔Example〕

An embodiment of this invention will be described based on the drawings.

The handling cylinder 1 is rotatably mounted in the handling chamber 6 in the direction of arrow A, and a receiving net 2 is stretched along the lower outer periphery of the handling cylinder 1. A dust exhaust port 3 is provided at a location corresponding to the end of the handling cylinder 1 of the receiving net 2, which communicates with the swinging sorter @4 provided below.

The scraper 5 is located on one side of the handling chamber 6 and is provided in close proximity to the dust outlet 3 of the receiving net 2.

In the illustrated example, the swing sorting 41I starts from the upper end of the handling chamber 6! A vertically elongated spiral body 7 is rotatably mounted on a bearing so as to approach the spiral body 14, and is configured to be forcibly rotated by an appropriate power transmission mechanism. 8 is a foot chain stretched along the handling opening 9 of the handling room 6.

Reference numeral 10 denotes a diffusion vane provided at the lower end of the spiral body 7.

In the upper configuration, the husk is threshed by the rotation of the handling g41 while being held and transferred by the foot chain 8, and the single grains leak from the receiving net 2 and fall to the swing sorting shelf 4 below, Processed materials that do not leak out from the net 2 (kernels with stems, single grains, dumpling-shaped culm cuts, etc.) fall from the dust outlet 3 onto the swinging sorting shelf 4 below. Objects (such as broken culms that have become dumplings) try to be carried around by the rotation of the handling cylinder 1 without falling from the dust outlet 3, but the objects to be carried around come into contact with the spiral body 7 which is forcibly rotating. During this scraping process, the dumpling-like processed material is untangled and falls onto the swinging sorting shelf 4 below, and is then passed through the diffusion blades. 1
0, the processed material falls onto the oscillating sorter lI4 while being spread. Therefore, the waste to be processed falls early and prevents it from clogging the dust exhaust port 3, thereby increasing the dust removal efficiency. It is possible to improve the diffusion effect and prevent the particles from concentrating all at once and falling onto the @4, thereby increasing the sorting effect.

In addition, by dropping the carried processing material together with the single grains early, the number of so-called hanging grains that are carried along with the processing material and inserted into the stock side of the culm that is clamped by the foot chain 8 can be reduced. It reduces grain loss.

〔effect〕

In this invention, since the technical means as described above are taken, the material to be processed does not fall from the dust outlet 3 and is forcibly scraped off quickly by the material scraper 5 carried by the rotation of the handling cylinder. Threshing may occur due to blockage in the three dust exhaust ports and overload on the handling barrel.
This has the effect that good threshing and sorting action can be performed without deteriorating the sorting function.

[Brief explanation of drawings]
