Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Fig. 1 is a structure principle chart of the present utility model.
Embodiment
With reference to accompanying drawing, hang farm implements tilling depth apparatus for adjusting force behind this tractor and comprise the fuel tank 2 that is arranged on the tractor, distributor 21, power supply 5, be provided with oil pump 1 in the fuel tank 2, distributor 21 is through oil-feed oil duct A, oil return oil duct B is communicated with fuel tank 2, be connected with oil cylinder 20 on the oil cylinder oil duct C of distributor 21, in oil cylinder 20 passes through, outer lift arm is connected with and hangs assembly 19, the rocking arm 16 that hangs assembly 19 is installed on the rocker arm bracket of rear tractor by rocker arm shaft 14; the below suspended axle of rocking arm 16 flexibly connects with suspension assembly lower link; the top of rocking arm 16 is provided with rocking arm preloading spring 15, hangs on the assembly 19 suspension plough 18 is installed.On the oil return oil duct of distributor, be sealed and installed with magnetic valve 3, between rocking arm 16 and magnetic valve 3, be provided with the switching device that the control magnetic valve opens and closes, this switching device comprises that the inboard that is installed in Mud-guard flap for tractor is provided with switch enclosure 8, the pull bar 11 that travel switch 6 is installed in the switch enclosure 8 and can in switch enclosure 8, slidably reciprocates and stretch out backward, the rear end of pull bar 11 is provided with prong, being set with on the pull bar 11 can be along the sliding sleeve 9 that slidably reciprocates in it and answer with the contact pair of rollers on the travel switch 6, between sliding sleeve 9 and pull bar 11 front ends regulating spring 7 is installed, sliding sleeve 9 rear ends are processed with the conical surface of answering with the contact pair of rollers, during installation, the roller external diameter on the travel switch contact vertically is close on the external diameter of pull bar 11.Above rocking arm 16, be installed with driving lever 17, driving lever 17 inserts in the prong of described pull bar 11, on the pull bar 11 of switch enclosure 8 outer ends, backguy seat 12 is installed, be provided with backguy 10 between sliding sleeve 9 rear ends and the backguy seat 12, be provided with the backguy handle in the tractor proper site, the backguy handle is installed on the handle set, the backguy handle is connected on the backguy seat 12 through manual backguy, manually backguy is provided with backguy sheath 13, utilizes the closure of manual backguy control run switch 6, can reach identical effect.Described magnetic valve 3 is electrically connected with travel switch 6, power supply 5 through lead 4.
The operation principle of this adjusting device is as follows: during the tractor ploughing work, the distributor control crank is in " decline " position, this moment, oil-feed oil duct A, oil return oil duct B, the oil cylinder oil duct C of distributor all were communicated with, after mounted plough buries, continuous variation along with soil resistance, the lower link that assembly is hung in the mounted plough pulling moves forward and backward, lower link drives the rocking arm that links together and rotates along the rocker arm shaft axle center, form swing above rocking arm, the driving lever that is fixed on the rocking arm moves forward and backward by pull bar prong drive pull bar.The sliding sleeve that is connected as a single entity by regulating spring, backguy, backguy seat and pull bar also moves forward and backward with pull bar.When mounted plough was subjected to resistance excessive, the rocking arm oscillating quantity also strengthened, thereby moved after the pulling pull bar drives sliding sleeve, and the conical surface of sliding sleeve promotes the roller on the travel switch contact, utilizes leverage to make its roof pressure switch contact, and travel switch is disconnected, and cut off the electricity supply.When resistance is too small, the rocking arm backswing, pull bar is pushed forward and moves, and sliding sleeve breaks away from roller, and contact unclamps, and travel switch is combination again, connects power supply.
Owing at the oil return oil duct B place of distributor magnetic valve has been installed, by the degree of closing of solenoid control oil return oil duct, thereby controlled hydraulic system enters the oil mass and the oil pressure of oil cylinder.Magnetic valve is when power connection, and valve is return, and oil return oil duct gap is strengthened, and recirculating oil quantity strengthens; After power supply disconnected, valve was released under the thrust of spring, and oil return oil duct gap reduces, and recirculating oil quantity reduces.Under the situation that the oil pump oil inlet quantity remains unchanged, recirculating oil quantity is big, has just reduced the oil mass that enters oil cylinder, and system pressure is just low, and piston moves forward, drives inside and outside lift arm and reduces suspension height, and farm implements are descended, and deepens tilling depth.Otherwise then recirculating oil quantity is little, and the oil mass that enters oil cylinder is just many, and system pressure is just high, promotes piston and moves backward, drives inside and outside lift arm and improves suspension height, and farm implements are risen, and tilling depth shoals.Along with the continuous variation of mounted plough resistance, make the constantly swing of rocking arm top like this, make power supply disconnect repeatedly, connect, the oil mass that enters oil cylinder constantly changes thereupon, makes tilth even, and cultivating quality reaches agriculture requirement.
