Laser land leveler and control system thereof

Abstract

The invention discloses a laser land leveler and a control system thereof. The laser land leveler comprises a laser emitter, a laser receiver, an angle sensor, a controller, a mast, a hydraulic system and an actuating device, wherein the laser receiver and the angle sensor are arranged on the mast to send instructions to the controller, the hydraulic system can drive the actuating device to adjust the position of a land leveling shovel according to the operation instructions sent by the controller, and the actuating device can adjust the horizontal position of the land leveling shovel to enable the laser land leveler to have a function of automatically adjusting the horizontal position of the land leveling shovel. By means of the technical scheme, the levelness of an operating face of the laser land leveler can be automatically or manually adjusted to guarantee that the laser land leveler always keeps horizontal in different work states.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a laser grader and a control system thereof. Background technique [0002] The use of laser levelers in farmland farming is very common today. The practical effect of laser leveling systems on transforming saline-alkali land into cultivated land has been practiced in Inner Mongolia, Ningxia and other regions. Today's laser graders only control the height of the shovel to improve the accuracy of land leveling in the field. However, when leveling the land with a large height difference, it is necessary to adjust the shovel according to the different ground heights during the operation. After the leveling shovel has been adjusted many times, the horizontal position of the leveling shovel is very easy to change, causing the land after leveling to meet the flatness requirements but not in the horizontal position, resulting in the land leveled by the laser leveler. There is an in...

Today's laser graders only control the height of the shovel to improve the accuracy of land leveling in the field. However, when leveling the land with a large height difference, it is necessary to adjust the shovel according to the different ground heights during the operation. After the leveling shovel has been adjusted many times, the horizontal position of the leveling shovel is very easy to change, causing the land after leveling to meet the flatness requirements but not in the horizontal position, resulting in the land leveled by the laser leveler. There is an inclination angle at the horizontal position, and the land level after different leveling processes is very different, resulting in poor leveling effect and reduced accuracy
