Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an angle adjustment mechanism of an armrest for agricultural machinery. Background Art

[0002] The handrails on walk-behind agricultural machinery are usually processed by bending steel pipes. However, during the bending process, it is difficult to ensure that all the handrail tubes have the same specifications. The most common problem is that the angles of the two handrails are different. If the unified standard is strictly followed, the rework of these accessories will be very large, affecting the processing efficiency. At the same time, because the handrail is a general accessory of agricultural machinery, strict precision is not required. In order to reduce the rework of the handrail tube and ensure that the handrail tube can be used smoothly on the agricultural machinery, and after the handrail tube is used on the agricultural machinery for a long time, it will also be deformed by force, affecting its use. Therefore, there is an urgent need for an armrest angle adjustment mechanism to change the installation angle of the armrest to compensate for processing errors or deformation due to force. Utility Model Content

[0006] A further technical solution is: the fixing plate is provided with a plurality of threaded holes arranged along the circumferential direction.

[0007] A further technical solution is: the armrest seat plate is also provided with the threading tube, and the fixing plate is provided with an arc groove matched with the threading tube.

[0008] A further technical solution is: a wire outlet hole is arranged on the side plate.

[0009] A further technical solution is that the armrest clamp is arranged away from the threading tube, the rotating outer sleeve and the rotating inner sleeve.

[0011] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0012] The utility model provides an angle adjustment mechanism for an armrest for agricultural machinery. When an error occurs in the processing of the armrest tube, or the armrest tube is deformed due to stress after being used on the agricultural machinery for a long time, the angle adjustment mechanism can compensate for the error of the armrest in the horizontal direction by adjusting the angle of the armrest seat plate on the fixed plate.
