Embodiment

[0019] The trailer-type laser grader of the present embodiment, such as figure 1 As shown, it includes a frame, a shovel and an elevation control system for adjusting the height of the shovel. The frame is provided with a wheel shaft 8, and the two ends of the wheel shaft 8 are respectively provided with a first ground wheel 7 and a second ground wheel 11.

[0020] The altitude control system in this embodiment is the prior art, and reference can be made to the background art, and only a brief description is made here. The laser transmitter (not shown in the figure) is set according to the elevation, and the laser receiver 1 is installed on the mast 2 of the shovel frame 9 (used to install the shovel) to receive the laser beam signal, thereby detecting the elevation of the shovel relative to the elevation Poor, then the elevation of the ground blade is controlled by the hydraulic control device 4.

[0021] This embodiment also includes an angle sensor 3 installed on the flat ...

Abstract

The invention relates to a pull type laser land leveler which comprises a rack and a land leveling shovel. A wheel shaft is fixedly arranged on the rack. The two ends of the wheel shaft are provided with a first land wheel and a second land wheel respectively. The pull type laser land leveler further comprises an angle sensor, a power cylinder, an eccentric rotation piece, a supporting piece and a controller, wherein the angle sensor and the power cylinder are arranged on the land leveling shovel, the eccentric rotation piece is hinged to the wheel shaft, and the supporting piece and the controller are fixed to the wheel shaft. The first land wheel is hinged to the eccentric rotation piece, a piston rod of the power cylinder is hinged to the eccentric rotation piece, and a cylinder body of the power cylinder is hinged to the supporting piece. The hinge point between the eccentric rotation piece and the wheel shaft, the hinge joint between the eccentric rotation piece and the piston rod of the power cylinder and the hinge joint between the eccentric rotation piece and the first land wheel are distributed in a triangular mode, the controller is used for obtaining the angle of the land leveling shovel measured by the angle sensor in real time, and the piston rod of the power cylinder is controlled to stretch out and draw back through the angle so that the land leveling shovel can be kept in a horizontal state. The land leveler can guarantee the level precision of the ground just by one-time work.

Description

technical field [0001] The invention relates to a towed laser grader, which belongs to the technical field of agricultural machinery. Background technique [0002] The surface flatness of farmland is relatively poor, which reduces the utilization rate of irrigation water and fertilizer use in farmland to a certain extent. Laser control leveling technology has important application value in improving the flatness of farmland surface, improving the uniformity of irrigation water distribution in farmland, and reducing the amount of fertilizer used. [0003] The existing laser leveling technology is to use a laser transmitter to emit a beam of laser, and the scanning plane generated when it rotates is used as a reference horizontal datum for controlling the unevenness of the ground. The laser receiver is a laser beam signal receiving device, which can automatically search the laser reference plane in all directions. The laser receiver is installed on the mast of the shovel, an...
