Problems solved by technology

The above applications are all in the form of ordinary wheels with a small width, which has little impact on leveling operations in large areas. However, when used in small areas, the design of the sinking wheel sometimes causes the wheels to penetrate too deep into the soil, which affects the leveling effect

Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with specific embodiments.

[0030] A suspended dry land laser grader comprises a three-point suspension device, a leveling unit, a floating unit, and an elevation adjustment device. A mast is installed on the flat unit, a laser receiver is installed on the mast, and a laser transmitter is installed on the ridge.

[0031] The floating unit includes a spiral wheel connecting frame and a spiral support wheel. Each spiral support wheel includes a spiral wheel, a plurality of spiral wheel spokes, two spiral wheel hubs, and a spiral wheel shaft; the spiral wheel shaft passes through the center of the spiral wheel, and the spiral wheel shaft and the spiral wheel pass through a plurality of spiral wheel spokes Connection, the helical wheel shaft head is located at the two ends of the helical wheel shaft, and the helical wheel shaft head is rotatably connected with the helical wheel connecting frame...

Abstract

The invention relates to a suspension-type dry land laser land leveler, which comprises a three-point suspension apparatus, a land-leveling unit, a floating unit and an elevation adjusting apparatus,the land-leveling unit is connected with a tractor through the three-point suspension apparatus, the land-leveling unit is hinged to the floating unit, the elevation adjusting apparatus is installed between the land-leveling unit and the floating unit, the floating unit is supported on the field surface, the land-leveling unit rises and falls relative to the floating unit by the elevation adjusting apparatus, the floating unit includes spiral supporting wheels, the spiral supporting wheels are hollow spiral strip structures, and the width of the spiral supporting wheels corresponds to the land-leveling width of the land-leveling unit. The invention also relates to a suspension-type dry land laser land-leveling method. The spiral supporting wheels are used as a lifting apparatus of a land-leveling shovel, supporting surface is enlarged, and the field surface is uniform in stress. The land-leveling shovel is lifted by the tractor three-point suspension manner and retreats to a field corner to realize field corner leveling. The land leveler and the land-leveling method are suitable for precise laser land-leveling operation in a small area, and belong to the technical field of farmland-leveling machines.

Description

technical field [0001] The invention relates to a farmland leveling machine tool, in particular to a suspended dryland laser leveler and a leveling method. Background technique [0002] The water-saving benefits and yield-increasing benefits of the finely leveled land are obvious, which is conducive to farming with agricultural machinery and improves the utilization rate of cultivation facilities. At present, the traction-type dry land laser grader on the market is only suitable for large-area and long-distance operations, and it is often impossible to achieve small-area leveling, field U-turn, field turning, and fast reciprocating operations. For example, a laser grader (CN201711187282.0) uses a scraper to level the ground, uses ground wheel movement and auxiliary leveling; a satellite grader (CN201711343551.8) uses flat ground to level the ground, and uses tire movement and auxiliary leveling; An articulated laser grader that can balance left and right (CN201710910559.1),...
