operating principle
In the planish process, the laser emitter give light beams which can swirling 360°. The plane surface made by the swirling light is the datum plane. According to the altitude difference between the hight of datum plane and the laser receiver that made by the the oporator, the controller can contorl the process. After dealing with the altitude difference information, it will send electrical signal to control hydraumatic regulator valve to adjust the hight of scraper blade automatically, and then keep with the datum mark.
System characteristics
The light beams made by laser emitter is harmless to human.
The semidiameter of operating scope should be no less than 300 meters.
The laser emitter can planish the farmland automatically, easy to operate.
The laser receiver can receive omnibearingly of 360°, can reach all the distracts.
The laser receiver can go up and down automatically, improve the effective altitude difference to ±40cm.
The controller has the automatic and manual drive function, easy to operate, with high accuracy.
Protect function of flat scoop when overloaped.
Outer hydraumatic control system, match with most tractors.
