Laser receiver for laser land leveling machine

Abstract

The invention discloses a laser receiver for a laser land leveling machine. An angle sensor is arranged in a laser receiver body, is connected to the laser receiver body and sends detected scraper pitch angle and roll angle data to the laser receiver. By adopting the technical scheme, the laser land leveling machine has the function of correcting and compensating the work surface levelness automatically, and the work surface of the laser land leveling machine is retained horizontally in different operating states constantly.

Description

technical field [0001] The invention relates to the field of agricultural equipment, in particular to a laser receiver for a laser grader. 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, but when leveling the ground with a large height difference, it is necessary to adjust the position of the shovel according to the different ground heights during the operation. After one adjustment, the horizontal position of the shovel is easily changed. According to this problem, an inclination sensor is usually installed on the shovel to detect the horizontal position of the shovel. However, in the prior art, only the pitch angle of the shovel is detected. It is easy to cause the roll angle of the leveling shovel...

Problems solved by technology

Today's laser graders only control the height of the shovel, but when leveling the ground with a large height difference, it is necessary to adjust the position of the shovel according to the different ground heights during the operation. After one adjustment, the horizontal position of the shovel is easily changed. According to this problem, an inclination sensor is usually installed on the shovel to detect the horizontal position of the shovel. However, in the prior art, only the pitch angle of the shovel is detected. It is easy to cause the roll angle of the leveling shovel not to be at the horizontal reference, but the inclination sensor is not detected, resulting in that the leveled land cannot meet the flatness requirements of the operation in the horizontal position, and the land obtained by the laser grader is always relative to the horizontal position. There is an inclination angle, and the land level after different leveling processes is very different, resulting in poor leveling effect and reduced accuracy
