I. Overview of laser land leveler
Laser land leveler is a modern agricultural machinery that uses laser technology to achieve high-precision land leveling. It is mainly composed of laser transmitter, laser receiver, control system and hydraulic actuator. The system uses the laser plane as a reference to detect the ground height deviation in real time, automatically control the lifting and lowering of the blade, and achieve centimeter-level or even millimeter-level land leveling accuracy.
II. Core technology principle
1. Laser reference system
Using a red laser with a wavelength of 635-650nm, the emission power is usually 1-5mW.
The rotating laser transmitter can form a 360° reference plane with a working radius of up to 300-800 meters.
The plane accuracy can reach ±1mm/10m, meeting the requirements of high-standard farmland construction.
2. Intelligent control system
Adopting PID control algorithm, the response time is <0.1 seconds.
Equipped with a high-precision tilt sensor with a measurement accuracy of ±0.1°.
Supporting GNSS/RTK positioning system fusion to achieve three-dimensional precision control.
3. Hydraulic actuator
Adopts electro-hydraulic proportional valve control, with flow regulation accuracy of ±2%.
Working pressure range 16-25MPa, adjustable lifting speed.
Equipped with overload protection device to ensure safe operation of equipment.
III. Technical advantage analysis
