Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the threshing drum in the axial flow threshing adopts a circular casing, which is easy to wrap grain and adopts a non-circular casing, because the angle of the guide vanes is the same, and it is impossible to harvest easily entangled crops such as wheat and rice or corn. To solve the problem of crops that are easy to thresh, and when harvesting the crops that are easy to thresh, it is easy to run out of grain, and then provide a cover for the axial flow threshing drum

specific Embodiment approach 1

[0007] Specific implementation mode one: combine figure 1 and figure 2 Describe this embodiment. A casing for an axial-flow threshing drum in this embodiment includes a housing 1 and a guide vane set 2. The guide vane set 2 includes a second guide vane 2-2, a third guide vane 2 -3 and a plurality of first guide vanes 2-1, which also includes two plug-in plates 3 and two speed-limiting baffles 4, the housing 1 is provided with an end face parallel to the housing 1 along the width direction of the housing Two parallel openings 1-1, on the inner wall of the housing 1 between the feeding port and the opening 1-1 near the feeding port side, there are a plurality of first ones evenly distributed and parallel along the length direction of the housing 1. Guide vane 2-1, a second guide vane 2-2 is fixedly attached to the inner wall of housing 1 between the opening 1-1 on the side of the feed opening and the opening 1-1 on the side of the crop outlet, A third guide vane 2-3 is affixe...

Abstract

The invention discloses a housing for an axial flow threshing cylinder, relates to a housing for a threshing cylinder and belongs to the field of agricultural machinery in order to solve the problems that grains are easy to paste because the conventional threshing cylinder adopts a circular housing during axial flow threshing, the conventional threshing cylinder adopting a non-circular housing cannot compatibly harvest crops (such as wheat, rice and the like) which are easy to coil or crops (such as corns and the like) which are easy to thresh because angles of guide blades are the same, and crops which are easy to thresh and are harvested by the conventional threshing cylinder are easy to lose. The housing for the threshing cylinder comprises a shell, a guide blade group, two insertion plates and two speed limiting baffle plates, wherein two openings are formed in parallel on the shell along a width direction of the shell; a plurality of first guide blades are uniformly distributed on and fixedly connected in parallel with the inner wall of the shell between a material feeding opening and the opening close to one side of the material feeding opening along a length direction of the shell; a second guide blade and a third guide blade are fixedly connected with the inner wall of the shell; and the speed limiting baffle plates pass through hollow cavities of the insertion plates and are inserted in the openings on the shell so as to be detachably connected with the insertion plates. The housing is matched with the threshing cylinder of a combined harvester or a thresher for use.

Description

technical field [0001] The invention relates to a casing for a threshing cylinder, which belongs to the field of agricultural machinery. Background technique [0002] At present, most of the crop threshing devices at home and abroad use axial flow threshing. However, among these threshing devices, such as the casing of the threshing drum of the combine harvester that combines harvesting and threshing and the casing of the threshing drum of the thresher that is used alone for threshing Most of them are round, and their disadvantage is that they are easy to entangle grains, and it is not easy for crops to move backwards when they are turned on the spot. Non-circular casings are not suitable for harvesting easily entangled crops such as wheat and rice because of the same angle of guide blades. Or easy-to-thresh crops such as corn, and it is easy to lose grain when harvesting easy-to-thresh crops. Contents of the invention [0003] The purpose of the present invention is to s...
