It carries out smooth on ground afterwards, is specifically, using level ground as the plane of reference, when formation plate tilts forward and back or tilts, i.e.,
When being not parallel to level ground of formation plate at this time, it may be necessary to adjust formation plate, makes the burnishing surface of formation plate（The bottom of formation plate
Place plane）Always it is parallel with level ground；When formation plate tilts backwards, i.e., the bottom on front side of formation plate is less than after formation plate
During the bottom of side, by control angular adjustment cylinder telescopic rod it is flexible for, as shown in figure 5, for convenience of description, threeway four
The oil inlet of position proportional reversing valve one is P mouthfuls, and the oil outlet of three-way four-position proportional reversing valve one is T mouthfuls, and three-way four-position ratio is changed
It it is A mouthfuls to a delivery outlet of valve one, another delivery outlet of three-way four-position proportional reversing valve two is B mouthfuls, three-way four-position ratio
The left end of reversal valve one is electromagnet one, and the right end of three-way four-position proportional reversing valve one is electromagnet two, and controller controls electromagnetism
Iron one must not be electric, and electromagnet two must be electric, and P mouthfuls are connected with B mouthfuls, and T mouthfuls are connected with A mouthfuls, and the oil in fuel tank is sucked out vane pump, there is pressure
The hydraulic oil of power adjusts the rod chamber of cylinder from P mouthfuls by B mouthfuls of entry angle, and hydraulic oil is from A mouthfuls in the rodless cavity of angular adjustment cylinder
Fuel tank is back to by T mouthfuls, the telescopic rod of angular adjustment cylinder is gradually retracted, and the telescopic rod of angular adjustment cylinder drives the formation plate inverse time
Needle to turning over, the levelness in the real-time detection level portion of gyroscope, i.e. horizontal part angle of inclination in the front-back direction and left and right directions
Angle of inclination, when horizontal part angle of inclination in the front-back direction is the threshold value of setting, controller control electromagnet two powers off, P mouthfuls,
T mouthfuls, A mouthfuls and A mouthfuls obstructed, the telescopic rod stopping action of angular adjustment cylinder；When formation plate turns forward, i.e., on front side of formation plate
Bottom less than the bottom on rear side of formation plate, controller control electromagnet one it is electric, electromagnet two must not electricity, P mouthful connect with A mouthfuls
Logical, T mouthfuls are connected with B mouthfuls, and the oil in fuel tank is sucked out vane pump, and the hydraulic oil for having pressure is adjusted from P mouthfuls by A mouthfuls of entry angle
The rodless cavity of cylinder, hydraulic oil is back to fuel tank from B mouthfuls by T mouthfuls in the rodless cavity of angular adjustment cylinder, angular adjustment cylinder without bar
The oil pressure of intracavitary is higher than the oil pressure in rod chamber, and the telescopic rod of angular adjustment cylinder gradually stretches out, the telescopic rod band of angular adjustment cylinder
Dynamic formation plate turns over downwards clockwise, the levelness in the real-time detection level portion of gyroscope, i.e. horizontal part angle of inclination in the front-back direction
With the angle of inclination of left and right directions, when horizontal part angle of inclination in the front-back direction is the threshold value of setting, controller control electromagnetism
Iron one powers off, and P mouthfuls, T mouthfuls, A mouthfuls and A mouthfuls obstructed, the telescopic rod stopping action of angular adjustment cylinder, so as to formation plate front-rear direction
Angular adjustment finish；Meanwhile formation plate is when also having inclination in the lateral direction, for example, when formation plate is tilted to the left, i.e., it is smooth
The right side height of plate is higher than left side height, if horizontally-supported seat is located at horizontal part center position to the right, controls automatic horizontal cylinder
Telescopic rod retract, the principle of control automatic horizontal cylinder action is identical with angular adjustment cylinder, and which is not described herein again, automatic horizontal cylinder
Telescopic rod connection shaft is driven to move downward, connection shaft gives supporting rod downward pressure, and supporting rod pushes horizontally-supported seat
The center of rear support seat was to lower swing, the levelness in the real-time detection level portion of gyroscope, when inclining for horizontal part left and right directions in the past
When rake angle is the threshold value of setting, the stopping action of control automatic horizontal cylinder；When formation plate is tilted to the right, i.e. the right side of formation plate
Highly less than left side height, the telescopic rod of control automatic horizontal cylinder stretches out, and telescopic rod drives connecting seat to move up, connecting seat band
Dynamic connection shaft moves upwards, and connection shaft hauls supporting rod and moves upwards, and supporting rod is driven on the right side of horizontal part around front and rear branch
The horizontal rotating shaft one connected on support seat is swung up, and is mutually parallel so as to which the bottom for making formation plate is remained with level ground,
It is not influenced by external environment or tractor operating mode, during leveling operation, the formation plate for adjusting hypsokinesis is upward counterclockwise
When turning over, elastic pressure bar is compressed, and plays cushioning effect；Angular adjustment terminates, and elastic pressure bar applies formation plate downward pressure,
Formation plate is made to be tightly attached to ground always, improves planarization effects；During rotary tillage leveling operation, driver can be big according to farmland
The location of small and agricultural machinery, control hydraulic handle cause extension cylinder to stretch out or retract, to achieve the purpose that the smooth wide cut of adjustment；
The utility model can be realized smooth on the ground after rotary tillage, can adjust formation plate in real time on front-rear direction and left and right directions
Levelness makes the burnishing surface of formation plate be close to always and is parallel to level ground, and flatness is uniform, and planarization effects are good；It adjusts flat
During the levelness of whole plate, angular adjustment cylinder will not generate torsion to connector one, when angle in the front-back direction is adjusted, around
Horizontal rotating shaft two rotates, and is fulcrum around horizontal rotating shaft using the center of horizontally-supported seat when the angle of left and right directions is adjusted
One rotation, front and rear support base will not generate torsion, improve the service life for being used for the structure that tightening angle adjusts cylinder；Elasticity pressure
The setting of bar pushes down formation plate close proximity to ground, further improves planarization effects；Extending apparatus is compact-sized, can be according to farmland reality
Border situation adjusts smooth wide cut in real time, meets the requirement of leveling operation；The rotary tillage that the utility model can be applied to each paddy field is put down
In whole operation.
The utility model is not limited to above-described embodiment, horizontally-supported seat, automatic horizontal cylinder etc. and can also be provided at planker
The position to the left at horizontal part center, on the basis of technical solution disclosed in the utility model, those skilled in the art according to
Disclosed technology contents, some of which technical characteristic can be made some replacements and become by not needing to performing creative labour
Shape, these are replaced and deformation is within the protection scope of the present utility model.
