Description
Technical field
The utility model relates to a kind of pavement construction machinery, particularly relates to a kind of formula of putting on a suit of armour for ground leveling and to stretch land leveller.
Background technology
Land leveller is the earth moving plant utilizing scraper ground grading, and constructing roadbed and road surface, build side slope, building site leveling, the fields such as municipal engineering are widely used.In theory, the span of land leveller front-rear axle is larger, and its leveling effect is better, but the increase of wheelbase causes land leveller longer, works dumb, operates and brings very large inconvenience, be not especially suitable for the construction in middle-size and small-size building site to turn to, tune etc.Have the land leveller of perching knife automatic regulation function at present, its perching knife is many carrys out adjusting angle by Wheel-type whirligig, and often need by independent hydraulic system, reductor to provide power, structure is comparatively complicated, and running cost is high.In addition, current main flow land leveller mostly is integral design, and be furnished with special power walking device, acquisition cost is high, and cost performance is to be improved.
Utility model content
For overcoming above-mentioned technical problem, the utility model provides a kind of reasonable in design, stable, can conditioner body length as required, be convenient to turn to, reverse end for end, bring convenience especially to midway transfer, and relative inexpensiveness, drive the formula of putting on a suit of armour run to stretch land leveller by existing tractor.
For realizing above-mentioned technical purpose, the utility model adopts following technical proposals: the one formula of putting on a suit of armour is stretched land leveller, frame is provided with in drive unit front end, frame front end is provided with front-wheel, the hitch frame of front end by front wheel supporting is provided with below frame, be provided with lift cylinder and oscillating oil cylinder between the rear end of hitch frame and frame, the downside of hitch frame is installed on perching knife; It is characterized in that: described frame and hitch frame all adopt two-part stretching structure, and be all installed on the telescopic oil cylinder controlling retracted position; Described perching knife is fixed on below hitch frame rear end by rotary knife base, angle modulation oil cylinder is provided with between described rotary knife base and hitch frame, the pin joint of angle modulation oil cylinder and rotary knife base is positioned at the side of rotary knife base axis of rotation, be provided with in described drive unit as above-mentioned hydraulic part provides the hydraulic power unit of hydraulic pressure, above-mentioned hydraulic part adopts solenoid control.
Described drive unit is tractor, and hitch frame rear end is fixedly connected with tractor body by connection bracket.
Described frame and hitch frame all adopt plug-in type stretching structure, and namely one section is inserted another intersegmental part, and realizes Telescopic.
The extendable temple members portion of described frame and hitch frame is parallel to each other, and two telescopic oil cylinders are also parallel.
The utility model has following beneficial effect: because frame and hitch frame have employed telescopic design, can the length of flexible modulation land leveller under the control of telescopic oil cylinder, can ensure to there is enough spans to improve leveling effect, again can turning to, reverse end for end, level land transfer time shorten the length of land leveller, improve the convenience of aforesaid operations; Its perching knife adopts angle modulation oil cylinder to carry out control angle, achieves automatic adjustment, and type of drive is comparatively simple, stable, failure rate is low; In addition, it adopts puts on a suit of armour formula design, is driven and provides hydraulic power, greatly reducing the acquisition cost of land leveller, make it be more prone to apply by existing tractor.
