Therefore it can not realize and car body is realized according to the variation of operating environment for car body leveling mode major part or manual leveling at present
Automatic leveling so that the drive safety of driver cannot ensure.
The content of the invention
In order to overcome above-mentioned technical problem, the present invention provides can self-leveling cropper stand alone type hydro pneumatic suspension car body
Design.
The present invention solves its technical problem and adopts the technical scheme that：It can self-leveling cropper stand alone type hydro pneumatic suspension
Car body design, including car body, convex connected unit, hydro pneumatic suspension device, wheel hub, connection hub shell, hemispherical Shell, rear axle, preceding bridge, through type
Trailing link, the hydro pneumatic suspension device include：Oil pressure sensor, hydro pneumatic suspension cylinder, accumulator, six rib holes, circular arc connection
Platform, draft platform, the oil pressure sensor are mounted on hydro pneumatic suspension cylinder, and oil pressure sensor can monitor hydro pneumatic suspension cylinder in real time
The variation of interior oil pressure by the way that the signal collected is transmitted to controller, to adjust the size of the oil pressure of hydro pneumatic suspension cylinder, institute in real time
Accumulator and six rib holes are stated by shaft hole matching, the six ribs hole passes through shaft hole matching, the circular arc connection with circular arc connecting table
Platform is mounted on draft platform.
Further, the car body coordinates with convex connected unit, the convex connected unit and hydro pneumatic suspension cylinder, the wheel hub
Together with being bolted with connection hub shell, the hub shell welds together with draft platform, and the hemispherical Shell is matched somebody with somebody with connection hub shell
It closes, the preceding bridge is coordinated with hemispherical Shell by bolt, and the rear axle and through type trailing link are described straight by shaft hole matching
General formula trailing link, by shaft hole matching, when vehicle is braked, quickly average load can prevent rollover phenomenon with preceding bridge
Generation.
Beneficial effects of the present invention：It is simple in structure, oil pressure sensor be mounted on hydro pneumatic suspension cylinder on, cropper work when by
In the variation of working environment the stress of hydro pneumatic suspension cylinder is caused to change, oil gas can be detected by oil pressure sensor in real time
The information of acquisition is transmitted to controller by the size of oil pressure in suspension cylinder, oil pressure sensor, and controller is according to the journey set in advance
Sequence realizes that the independent-lifting of 4 hydro pneumatic suspension cylinders, it can be achieved that automatic leveling, avoids car body from turning on one's side, protects operating personnel's
Life security.

Specific embodiment
A kind of car body automatic leveling based on agricultural harvesting machinery of the present invention is visited with reference to Figure of description 1 to attached drawing 5
Lever apparatus is described in detail below.
A kind of car body automatic leveling probe device based on agricultural harvesting machinery, including car body 1, convex connected unit 2, oil gas
Draft hitch, wheel hub 9, connection hub shell 10, hemispherical Shell 11, rear axle 12, preceding bridge 13, through type trailing link 14, the oil gas hanging
Rack device includes：Oil pressure sensor 3, hydro pneumatic suspension cylinder 4, accumulator 5, six rib holes 6, circular arc connecting table 7, draft platform 8, the oil
Pressure sensor 3 is mounted on hydro pneumatic suspension cylinder 4, and oil pressure sensor 3 can monitor the change of oil pressure in hydro pneumatic suspension cylinder 4 in real time
Change, by the way that the signal collected is transmitted to controller, to adjust the size of the oil pressure of hydro pneumatic suspension cylinder 4, the accumulator 5 in real time
With six rib holes 6 by shaft hole matching, with circular arc connecting table 7 by shaft hole matching, the circular arc connecting table 7 is pacified in the six ribs hole 6
On draft platform 8.
Further, the car body 1 coordinates with convex connected unit 2, the convex connected unit 2 and hydro pneumatic suspension cylinder 4, described
Together with wheel hub 9 is bolted with connection hub shell 10, the hub shell 10 welds together with draft platform 8, the hemispherical Shell
11 coordinate with connection hub shell 10, and the preceding bridge 13 is coordinated with hemispherical Shell 11 by bolt, the rear axle 12 and through type longitudinal thrust
