Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with specific embodiments.

[0032] A paddy field laser grader with profiling support, including a frame, an elevation adjustment device, an elevation device, a leveling device, and a left and right leveling device. The frame is connected to the tractor through a three-point suspension device, and the elevation device is connected to the The frame is connected to adjust the height of the elevation device, and the leveling device is connected to the elevation device and leveled left and right through the left and right leveling devices; it also includes the profiling support roller installed under the frame; the profiling support roller passes through the frame and three The point suspension device is floatingly connected with the tractor. During operation, the profiling support roll is supported by the mud surface of the paddy field for profiling and has nothing to do with the movement posture...

Abstract

The invention relates to a laser land leveler for a paddy field with a copying supporting roller. The laser land lever comprises a rack, an elevation adjusting device, an elevation device, a land leveling device and a left and right leveling device, wherein the rack is connected to a tractor through a three-point suspension device, the elevation device is connected to the rack through the elevation adjusting device to adjust the height of the elevation device, and the land leveling device is connected to the elevation device and is leveled left and right through the left and right leveling device. The laser land leveler further comprises the copying supporting roller mounted below the rack; the copying supporting roller is in floating connection to the tractor through the rack and the three-point suspension device. During work, the copying supporting roller is supported by a mud face of the paddy field to copy and is irrelevant to moving gesture change of the tractor, and the gesture change of the copying supporting roller causes gesture change of the land leveling device. A land leveling shovel is in lift control more stably, so that the land leveling quality and efficiency are improved. The operating precision is improved, and the laser land leveler belongs to the technical field of farmland levelers.

Description

technical field [0001] The invention relates to a farmland leveling machine tool, in particular to a paddy field laser leveler with profiling support rolls. Background technique [0002] A flat paddy field is the premise of mechanized farming and planting. It has the advantages of improving mechanical efficiency, uniform irrigation, saving water resources, facilitating field management, improving fertilizer utilization rate, and increasing crop yield. The invention patent "a foldable paddy field leveling machine" (CN103039142A) provides a foldable paddy field leveling machine with simple structure and good practicability. However, when the paddy field leveling machine is in use, the three-point suspension of the tractor can only be manually adjusted to realize the up and down movement of the implement, which cannot meet the requirements of precise leveling. The invention patent "a laser grader for paddy fields" (CN101223841A) judges the height of the flat-bottomed shovel th...
