Laser land leveling equipment for saline-alkali soil

Abstract

The invention provides laser land leveling equipment for saline-alkali soil. The laser land leveling equipment comprises a framework, a controller, rolling wheels, a rotary tillage leveling device arranged at the rear end of the framework, a laser emitter connected to the framework and a laser receiver installed at a ground base point. The framework is connected with an agricultural vehicle through a connecting port. The rotary tillage leveling device comprises a connecting frame hinged to the rear end of the framework, a supporting frame hinged to the rear end of the connecting frame, and a rotary tillage smashing device installed on the supporting frame; first air cylinders are hinged between the front ends of the two sides of the connecting frame and the framework, and second air cylinders are hinged between the rear ends of the two sides of the connecting frame and the front end of the supporting frame; and the rotary tillage smashing device comprises a smashing motor and a smashing assembly. The controller can judge the current ground height after acquiring signals of the laser emitter and the laser receiver, and the rotary tillage leveling device can be used for leveling theground. When the saline-alkali soil is leveled, the smashing motor can drive the smashing assembly to smash hardened soil blocks, and the flatness of the soil is high.

Description

technical field [0001] The invention relates to a laser land leveling device, in particular to a laser land leveling device for saline-alkali land. Background technique [0002] The direction of agricultural development tends to be mechanical automation. In the fields of arable land, sowing, irrigation and harvesting, the penetration rate of mechanical production is relatively high. The purpose of arable land is to loosen the soil and level the land to facilitate sowing of crops, and to irrigate the crops after leveling the land. At present, laser leveling equipment is used to level the land. The information of the ground height difference is obtained by the laser transmitter and the laser receiver, and then the ground is leveled by the rotary tillage and shoveling device. At present, the conventional laser graders on the market have a simple structure, and the adjustment range of the rotary tillage leveling device is limited, which makes it difficult to operate in differen...

AI Technical Summary

Problems solved by technology

At present, the conventional laser graders on the market are simple in structure, and the adjustment range of the rotary tillage and leveling device is limited. It is difficult to operate in different occasions, which has a great impact on land leveling operations.
