As a kind of improvement, the force information that is subjected to that described force feedback unit is measured and gathered is the force information that is subjected to of suspension lower link.
As further improvement, described force feedback unit is the power inductosyn.
As further improvement, described position feedback unit is an angular displacement sensor.
As further improvement, the Mud-guard flap for tractor rear portion is provided with the operating means that is connected with the tilling depth controller.
As further improvement, described lift cylinder is an one-way cylinder.
The deep-plowing raiser for tractor of technique scheme, owing to be the lift cylinder that has adopted the lifting of controlled suspension, the tilling depth control valve that is connected with lift cylinder, measuring and gather the suspension pull bar is subjected to the force feedback unit and the measurement of force information and gathers the position feedback unit of suspension lift arm rotary angle position information, with the tilling depth controller that force feedback unit and position feedback unit are connected respectively, the actuation unit that is connected with the tilling depth controller; Described tilling depth controller is connected with the tilling depth control valve, by signal transmission tilling depth controller with force feedback unit and measurement of position feedback unit and collection, by the processing of tilling depth controller and the control of actuation unit, thereby the work of control tilling depth control valve control lift cylinder realizes the adjusting to the facility tilling depth, improved the precision that the tractor tilling depth is adjusted greatly, effectively realized the power control of tractor tilling depth, Position Control, the power position Comprehensive Control and the control of floating, improve control performance, improve tractor complete machine performance, and also improved precision to suspension Position Control and resistance control function, realized stepless adjustable control to elevator system, because the major control element is electric control element, response speed is fast, the parameter of control system is easy to change, and adjustability is good, hydraulic system class and Hydraulic Elements reliability have been improved.The force feedback unit is subjected to force information by adopting the power inductosyn that is provided with to measure and gather on suspension upper connecting rod and lower link, improved certainty of measurement greatly, has made things convenient for the adjustment to the tractor tilling depth.And the position feedback unit adopts angular displacement sensor, has improved the accurate control to the suspension position.Be provided with the operating means that is connected with the tilling depth controller at the Mud-guard flap for tractor rear portion, can make things convenient for the articulate control of user facility on the tractor.
