Problems solved by technology

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

Embodiment Construction

[0027] The advantages of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0028] refer to figure 1 , is the working principle diagram of the laser grader control system of the present invention. The laser leveling device emits laser light to the laser receiver, and the laser receiver sends instructions to the controller according to the laser light sent by the laser transmitter. At the same time, the control system also includes an angle sensor. Connect with the leveling shovel to judge the horizontal position of the leveling shovel, and send the horizontal position information to the laser receiver. After the laser receiver receives the horizontal position signal, add the horizontal direction control command of the leveling shovel to the original command. The controller adjusts the position of the shovel in the above two directions according to the vertical direction control command and the horizo...

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...
