Description

technical field [0001] The invention relates to an electric mast for an agricultural laser grader, belonging to the technical field of agricultural machinery. Background technique [0002] The leveling of the farmland surface plays an important role in the yield of crops and the effective use of water and fertilizer. After leveling the surface of the farmland with a laser grader, the yield of crops can be increased, water can be saved, and fertilizer loss can be reduced. [0003] When the laser grader is working, in order to ensure that the laser receiver can receive the laser signal in real time and reliably, not only the receiving angle of the laser receiver is required to be large, but also the position and height of the laser receiver can be adjusted. Existing laser graders realize the adjustment of the position and height of the laser receiver through the expansion and contraction of the hydraulic cylinder to control the mast to move up and down. This control method ne...
