Embodiment Construction

[0056] Next, embodiments of the invention will be described.

[0057] First, the whole structure of the combine 1 provided with the threshing part 30 which concerns on one Embodiment of this invention is demonstrated. In addition, the combine harvester 1 is a whole straw input type combine which throws in the whole straw, such as a soybean or wheat, in the threshing part 30, and performs threshing.

[0058] like figure 1 As shown, the combine harvester 1 is equipped with a running part 10, a harvesting part 20, a threshing part 30, a sorting part 40, a grain storage part 50, a grass discharge processing part 60, an engine part 70, and a driving part with respect to the fuselage frame 2. 80.

[0059] The running part 10 is provided at the lower part of the fuselage frame 2 . The traveling unit 10 is configured to include a crawler-type traveling device 11 including a pair of left and right crawlers, and the crawler-type traveling device 11 can move the fuselage in the forwar...

Abstract

A threshing section for a combine can perform smooth threshing work with improved threshing performance achieved by making grain stalks less likely to tangle together into a rope-like shape. A threshing drum (31) of a threshing section (30) for a combine is provided with threshing teeth (313) arranged at the intersection points between a first helix (301) and a second helix (302) which are coaxial with the threshing drum (31), wound in the same direction, and arranged at different helical pitches. The threshing drum (31) is also provided with threshing teeth arranged at positions which are adjacent in the front-rear direction to the threshing teeth (313) and are reached before or after the first helix, which has a smaller helical pitch than the second helix, completes substantial one revolution. The threshing teeth (313) and the threshing teeth are arranged such that only some of the threshing teeth (313) and only some of the threshing teeth are overlapped on each other. In a concave (32), tube-shaped, sieving body-forming members (322A) of a sieving body (322) are mounted on a frame body (321).

Description

technical field [0001] The present invention relates to a threshing unit of a combine provided with a processing drum and a concavity. Background technique [0002] The threshing part of the conventionally known combine has the processing drum provided with the some processing teeth (for example, refer patent document 1). For this kind of threshing part, a plurality of processing teeth are installed on the outer peripheral surface of the body part in the processing drum, arranged in the circumferential direction of the processing drum along a spiral set with a predetermined pitch, and arranged in the processing drum along a straight line parallel to the axis of the processing drum. direction of the drum axis. [0003] Patent Document 1: Japanese Patent No. 2578075 [0004] In the threshing section of this existing combine harvester, according to the position of the above-mentioned processing teeth, when the processing drum is rotated during the threshing operation, a plura...
