Abstract

The invention discloses a laser land leveling control device and method. The device comprises a traction unit (20), a supporting wheel (4), a land leveling blade (16), a laser emitter (1), a laser receiver (5), a laser receiver lifting unit (6) and a controller (15), wherein the laser receiver lifting unit (6) is used for bearing the laser receiver (5) and the controller (15) is used for controlling lifting and falling of the laser receiver (5) and the land leveling blade (16). The invention overcomes the defect that the leveling operation efficiency is low because the vehicle is repeatedly stopped to adjust the height of the receiver, solves the problem that the tractor engine or the land leveling blade is damaged because of excessive load, avoids land heaving caused by slow response of a land leveling system after the supporting wheel of the land leveling blade is raised too high from reducing the land leveling operation quality, and realizes efficient and accurate land leveling operation.

Description

technical field [0001] The invention relates to the technical field of land leveling, in particular to a laser leveling control device and method. Background technique [0002] Surface flood irrigation is the main method of agricultural irrigation in my country. Improving the leveling of farmland can effectively improve the utilization rate of farmland irrigation water. Studies have shown that land leveling has obvious effects on farmland water saving, weed control, and crop income increase. Land leveling methods include conventional leveling methods and laser controlled leveling methods. The conventional mechanical leveling method is restricted by the defects of the machine itself and the limited accuracy of manual leveling. After reaching a certain level, the accuracy of land leveling cannot continue to be improved, and it cannot meet the requirements of fine irrigation. Laser measurement control leveling technology uses laser measurement plane and electronic control sys...
