Technical Field
The utility model relates to the technical field of agricultural machinery, in particular to a stepless angle adjusting device for a guide bar on a threshing cylinder cover of a full-feeding combine harvester.
Background
Present full feeding combine, its threshing cylinder covers the guide strip that generally adopts fixed knot to construct, can't adjust, because the environment of reaping and the influence of the different varieties in different areas, has two kinds of problems to produce when leading to threshing: one is that the rice straws or wheat straws which are not threshed completely are discharged; the other is the phenomenon that after the threshing is complete, the rice straws or wheat straws are continuously threshed in the threshing cylinder, thereby causing resource waste. However, a small part of all-feeding combine harvesters on the market have been changed, and the guide bars on the threshing cylinder cover can be adjusted in a step-by-step or stepless manner, the principle is that the guide bars on the threshing cylinder cover are controlled by a long handle to manually adjust the angle, and after the adjustment is finished, the long handle is fixed on a plurality of fixing holes or slotted holes on the threshing cylinder cover. The defect of this scheme is that the user when reaping after finishing adjusting, because the gib block can receive very big impact when leading to rice straw or wheat straw, these impacts can not be resisted completely to current gib block angle stepless regulation scheme, lead to the gib block to fix the long handle on threshing cylinder lid can take place slight displacement phenomenon under receiving very big external force impact to make the angle of gib block reduce gradually, need adjust repeatedly. Therefore, many manufacturers and knowledgeable persons develop and try to solve the above problems, but no ideal product is yet available.
