Technical Field

Background

The farmland surface leveling condition plays an important role in the yield of crops and the effective utilization of water and fertilizer, and after the agricultural laser land leveler is used for leveling the farmland surface, the yield of the crops can be improved, the water is saved, and the fertilizer loss is reduced.

When the agricultural laser land leveler works, the agricultural laser land leveler moves forwards under the traction of the tractor, and the computer control system controls the land leveler cutting edge to track and be parallel to the laser reference plane so as to level the surface of the farmland. In order to ensure that the land leveler can track the laser reference plane in a large range and ensure that the land leveler blade is always parallel to the laser reference plane, and reduce the influence caused by the transverse swing and longitudinal pitching of the tractor due to the fluctuation of the farmland surface, the land leveler is required to rotate transversely (around a coordinate axis X) at a large angle relative to the tractor and also required to rotate longitudinally (around a coordinate axis Y) at a large angle relative to the tractor; in order to ensure a small turning radius of the laser grader during transportation and operation, the laser grader is required to be freely rotatable in the horizontal plane (about the coordinate axis Z) relative to the tractor. The existing laser land leveller is connected with a tractor through a two-free tractor, and can only realize horizontal rotation and small-angle longitudinal swing relative to the tractor and cannot realize large-angle transverse swing relative to the tractor.
