A height-adjustable mechanical arm and a farmland ditch-drilling robot

Abstract

The invention relates to a height-adjustable mechanical arm and a robot for farmland ditching. The height-adjustable mechanical arm includes a vehicle frame and two sets of roller assemblies installed on both sides of the vehicle frame. The roller assemblies are included in Rotate the support frame mounted on the vehicle frame and the wheel mounted on the support frame. The support frame is covered with a movable sleeve that slides with it. The two supports on the same side of the vehicle frame The movable sleeve on the frame is rotatably connected with the driving rod movably installed on the vehicle frame, and the driving rod is slidably connected with the vehicle frame through a guide assembly, and is connected with a mobile driving mechanism arranged on the vehicle frame. Drive the driving rod to move horizontally through the moving drive mechanism, so as to cooperate with the action of the movable sleeve to drive the support frame to rotate to change the placement angle of the support frame. When connecting the ditch roller, the depth of the ditch can be adjusted without facing the ditch roller. The frame is adjusted to ensure the stability of the ditch roller during work.

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
