Description

Land leveller

The utility model relates to a kind of improvement of land smoothing machine, particularly a kind of land leveller.

Present employed land smoothing machine such as PY-160 and PY-180 its knife rest of series and perching knife are installed between the front and back wheel, in the level road process, if wheel runs into projection or pit, and have little time to fall or when rising perching knife, will on the road surface, form the protruding ridge or chase, just must carry out repeatedly smooth.PY-160 and PY-180 series do not have compaction apparatus and ridge buster, therefore also must have road roller again road pavement carry out compacting, time-consuming.PY-160 and PY-180 series adopts rear wheel drives, occurs freezing on the road surface or road surface quality when softer, occurs skidding easily.Though PY series land leveller is provided with the bamboo rake that loosens the soil, the bamboo rake tooth is few, and the effect of loosening the soil is bad, and needs the artificial lifting bamboo rake that loosens the soil.

The purpose of this utility model provides the land leveller that a kind of perching knife is installed in the frame front end, this land leveller high efficiency, and leveling effect is good, does not need repeatedly smoothly, and has replaced artificial operation with hydraulic means, has saved manpower.

The utility model is achieved in that a kind of land leveller, comprise rack-mounted driver's cabin and power set, by crossbeam and secondary crossbeam girder is coupled together the formation frame, girder inside is equipped with sprocket wheel, the frame outside is equipped with wheel, all sprocket wheels interconnect by roller chain, at the frame front end rotary case is installed, rotating disk is installed on the rotary case, the below of rotating disk is installed with perching knife, the hinged bamboo rake that loosens the soil that is equipped with in perching knife rear portion is installed with the hydraulic pressure compaction apparatus in frame lower, and the frame end is equipped with ridge buster.

When the utility model uses, motor drives sprocket wheel and gear pump rotates, sprocket wheel drives other all sprocket rotation by roller chain, sprocket wheel drives wheel by wheel shaft, because all wheels all are driving wheel, thereby avoided the phenomenon that driving wheel skids occurring because ground is soft or icing, while gear pump driven knife rest, perching knife, bamboo rake loosens the soil, the hydraulic means of ridge buster, control these device lifting and rotations, saved manpower and materials,, avoided because the out-of-flatness on ground again because perching knife of the present utility model is installed in the front end of frame, cause perching knife to have little time lifting, form the phenomenon of the protruding ridge or chase on the ground.

The utility model is done the description in a nearly step below in conjunction with accompanying drawing.
