Soil is after laser cultivated leveling ground workover rig is smooth, and field height difference is little, and flatness improves greatly, can ensure agricultural machinery sowing, rice transplanting the degree of depth one to, improve the availability of water resource, greatly save irrigation water, reach accurate water, efficiency of pouring water reaches 90%, can economize on water 30% ~ 50%.Decrease fertilizer loss and de-fertile phenomenon simultaneously, improve chemical fertilizer utilization ratio more than 10%.
Laser pickoff is fixedly attached on land level scraper by support bar, and because ground is uneven during operation, land level scraper can produce and move up and down and horizontal revolving motion under the control of laser and Hydraulic testing and controling system, i.e. the pose adjustment of land level scraper.The rotation of land level scraper can drive support bar to swing, and support bar length is more than 2m, and the swing of strut can bring the height change of laser pickoff in the vertical direction, brings comparatively big error to laser measurement.Make troubles to the initialization adjustment of equipment during operation simultaneously.
Utility model content
For the swing solving strut can bring the height change of laser pickoff in the vertical direction, comparatively big error is brought to laser measurement, bring troublesome problem to the initialization adjustment of equipment during operation simultaneously, propose a kind of receiver angle of inclination compensation arrangement being applied to laser flatting machine.
The utility model adopts following technical scheme:
Be applied to a receiver angle of inclination compensation arrangement for laser flatting machine, comprise land level scraper, described land level scraper is provided with connection hinge, and connect by pinned connection between hinge and rotating turret, rotating turret is provided with base, and base is provided with support bar; Oil cylinder is provided with between the lower right of described rotating turret and land level scraper, rotating turret upper surface is provided with obliquity sensor, and obliquity sensor is connected with data acquisition unit, and data acquisition unit connects and is connected with data processing controller, data processing controller is connected with hydraulic system, and hydraulic system is connected with oil cylinder.
Further, support bar overcoat has nut.
Further, between rotating turret and base, cushion blocking is provided with.
Further, base through screws is fastened on rotating turret.
The utility model has following beneficial effect:
Compared with prior art, this device of the utility model adopts obliquity sensor, can detect in real time, and complete the compensation at inclination angle fast by controller hydraulic control system to the pendulum angle of support bar, reliability is high, improves the precision of laser measurement system preferably.
Measurement data is treated drives oil cylinder to compensate support bar inclination angle by controller hydraulic control system; More finally realize support bar by the matching of feedback data and be in vertical state all the time, ensure the normal work of Laser Measuring Ore-controlling Role, improve its homework precision; The debugging difficulty before whole land leveller operation greatly can be reduced because support bar is in vertical state all the time.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As shown in Figure 1,2 and 3, a kind of receiver angle of inclination compensation arrangement being applied to laser flatting machine, comprises land level scraper 9, described land level scraper 9 is provided with and connects hinge 1, connect hinge 1 to be connected by bearing pin 2 with between rotating turret 7, rotating turret 7 is provided with base 6, and base 6 is provided with support bar 4; Oil cylinder 8 is provided with between the lower right of described rotating turret 7 and land level scraper 9, rotating turret 7 upper surface is provided with obliquity sensor 10, obliquity sensor 10 is connected with data acquisition unit, data acquisition unit connects and is connected with data processing controller, data processing controller is connected with hydraulic system, and hydraulic system is connected with oil cylinder; Support bar 4 overcoat has nut 5; Cushion blocking 3 is provided with between rotating turret 7 and base 6; Base 6 is connected by screw and is fixed on rotating turret 7.
Base 6 screw is fastened on rotating turret 7, adopts special fixture, and ensure the perpendicularity of base endoporus and rotating turret upper surface, allowance control is within 0.02.By rotating turret pinned connection on the hinge be fixed on land level scraper, and be connected with oil cylinder 8.According to hydraulic scheme, Hydraulic Elements are installed, and connect fluid pressure line.According to control system figure, connection control circuit.Adopt dedicated elas-tic centering collet chuck that support bar and machine-operated receiver are installed.Measure the depth of parallelism of rotating turret upper surface and horizontal plane, as initial data initialization controller.During land leveller operation, first open pour angle compensation system, the levelness of adjustment rotating turret upper surface, i.e. the perpendicularity of support bar and machine-operated receiver and horizontal plane, numerical value is less than 0.02.Then visually the flatness in smooth plot, open the initial attitude of Laser Measuring Ore-controlling Role adjustment land level scraper 9.Next, grading operation is started according to the operational procedure of land leveller and method.
During grading operation, when rotating turret 7 swings with the pose adjustment of land level scraper 9, obliquity sensor 10 can measure the angle between rotating turret 7 and horizontal plane at once.By data acquisition unit and treatment system, this inclination angle is passed to controller, the adhesive of hydraulic control valve be separated, to change the flow-direction and flowrate that hydraulic oil transfers to hydraulic cylinder, promote rotating turret to rotate round about, realize its pour angle compensation, ensure rotating turret all the time with plane-parallel, namely support bar 4 all the time with horizontal plane.In whole operation process, data acquisition unit gathers data each 2 seconds, and these data and upper data compare by data processor, judge the current location of rotating turret and support bar 4, and calculates the angle with horizontal plane, controls the stroke of oil cylinder 8.
