Elevation-adjustable mechanical arm and robot for farmland channeling

Abstract

The invention relates to an elevation-adjustable mechanical arm and a robot for farmland channeling. The elevation-adjustable mechanical arm comprises a frame and two groups of roller components arranged at two sides of the frame, wherein each roller component comprises a support frame rotationally arranged on the frame and a wheel rotationally arranged on the support frame; movable sleeves matched with the support frames in a sliding mode are arranged on the support frames in a sleeved mode; the movable sleeves on the two support frames located at the same side of the frame are rotationally connected to a drive rod movably arranged on the frame; and the drive rod is connected to the frame in a sliding mode through a guide component and connected to a moving driving mechanism arranged on the frame. The moving driving mechanism drives the drive rod to move horizontally, so that the support frames are driven to rotate under the action of the movable sleeves, the placement angles of the support frames are changed, when a channeling roller is connected, the channeling depth can be adjusted, the channeling roller does not need to be adjusted relative to the frame, and the stability of the channeling roller in the working process is guaranteed.

Description

technical field [0001] The invention relates to the technical field related to agricultural planting, in particular to an elevation-adjustable mechanical arm and a farmland ditch-drilling robot. Background technique [0002] In the irrigation area of ​​our country, there is usually a sealing slope between the irrigation canal and the farmland. The structure of the field water inlet on the agricultural canal is very simple. When it is necessary to introduce water into the farmland for irrigation, many agricultural producers currently dig a Small diversion canals, excavation canals are still partly excavated with shovels. When there are many water inlets in the field, it will be very labor-intensive to complete the canals. [0003] At present, there are many equipments for trenching on the market, but because the depth of trenching needs to be adjusted according to different needs, the existing ones generally use hydraulic cylinders to adjust the height of the trenching roller...

[0002] In the irrigation area of ​​our country, there is usually a sealing slope between the irrigation canal and the farmland. The structure of the field water inlet on the agricultural canal is very simple. When it is necessary to introduce water into the farmland for irrigation, many agricultural producers currently dig a Small diversion canals, excavation canals are still partly excavated with shovels. When there are many water inlets in the field, it will be very labor-intensive to complete the canals

[0003] At present, there are many equipments for trenching on the market, but because the depth of trenching needs to be adjusted according to different needs, the existing ones generally use hydraulic cylinders to adjust the height of the trenching roller relative to the frame, so as to realize the adjustment of the trenching depth. Due to the flexible connection between the ditch roller and the frame, although it is supported by a hydraulic cylinder, the ditch roller is still unstable during use
