Problems solved by technology

[0013] As mentioned above, if the combine harvester is equipped with the function of making the auger conveying mechanism automatically stand up to the stand-up limit position when the auger conveying mechanism passes above the driving part, it is necessary to detect various positions of the position of the auger conveying mechanism The sensor and the control mechanism that make the screw conveying mechanism automatically stand up to the stand-up limit position lead to a complicated structure and an increase in production cost

Embodiment Construction

[0098] Next, an embodiment of the first aspect of the present invention will be described with reference to the drawings.

[0099] figure 1 It is a vertical left side view of the threshing device in the combine harvester. Such as figure 1 As shown, the structure of the threshing device 101 in the combined harvester exemplified in this embodiment includes: a threshing part 106 having a threshing cylinder 104, a receiving net 105, etc., and a sorting part 107 arranged below the threshing part 106, wherein The threshing cylinder 104 performs threshing treatment on the harvested and transported straw that is clamped by the threshing feed chain 102 and transported into the threshing chamber 103 , and the receiving net 105 makes the treated material that has been processed by the threshing cylinder 104 leak to the bottom. That is, the harvested and transported straw is threshed between the threshing cylinder 104 and the receiving net 105 while being pinched and transported by the ...

Abstract

The invention provides a threshing device. Grains processed in one time can be smoothly drained and recovered with less doped straw bits and without relationship to the amount of processed grains drained from the shaker screen in one time. The threshing device comprises a threshing part and a selecting part, wherein the threshing part threshes the straws in a threshing chamber, the selecting part is used for performing shaking selection on the threshed grains by using the shaking screen device. The shaking screen device is provided with a grain shaking screen (110), and grains which are processed in one time are drained along a plurality of screen holes (125) formed in the transverse and vertically directions of the grain shaking screen (110). A plurality of elongated flexible parts (134) are arranged at intervals side by side at least at the upstream of the grain shaking screen (110), contacting with the grain shaking screen (110) and being quite close to each other.

Description

technical field [0001] The invention relates to a threshing device. The threshing part is used for threshing straw, the sorting part is used for sorting the threshed products, and the grains which are shaken and sieved are recovered as primary processed products. [0002] The present invention also relates to a combine harvester, which has a grain collection box and a screw conveying mechanism for discharging the grains stored in the grain collection box to the outside at the rear of the machine body, and has a driver's section at the front of the body and a The screw conveying mechanism is supported by the supporting part fixed on the body so that it can rotate around the upper and lower axes and can perform lifting operations around the horizontal axis. Background technique [0003] Conventionally, there is known a threshing apparatus as disclosed in Patent Document 1. This threshing apparatus has a threshing unit for threshing straw in a threshing chamber 2 and a sorting ...
