The specific embodiment
For further understanding technology contents of the present utility model, characteristics and effect, enumerate following example now, and conjunction with figs. is described in detail as follows:
With reference to accompanying drawing 1 and Fig. 2.
Land leveller ratio dual-handle control device has controller, dual-handle and electromagnetic valve group, and controller connects dual-handle and electromagnetic valve group, and electromagnetic valve group has the electromagnetic valve of selection and proportion magnetic valve, and dual-handle connects the selection electromagnetic valve respectively.Selecting electromagnetic valve is 4 automatically controlled selector valves, and proportion magnetic valve is a simply connected electricity proportional reversing valve.
Dual-handle is left handle and right handles, and left handle or right handles are provided with compound control button and perching knife, front-wheel, turn to, ejector dozer action electronic selection control button.Left handle or right handles electronic selection control button connect solenoid control left side or right side workpiece by controller respectively.Controller is when operation one side electronic operation handle, and controller is controlled the adjustment of 5 kinds of functions of land leveller the same side workpiece in proportion according to input signal, and can realize the Synchronization Control of opposite side appointed function.
The concrete structure of present embodiment and the course of work:
The composition of this device comprises 1 controller and 2 sleeving valve group and joysticks, and every sleeving valve group and joystick comprise: simply connected electricity proportional reversing valve, 4 automatically controlled selector valves, 1 electronic operation handle.
The basic principle of control system is that hydraulic pump (constant displacement pump or variable pump) provides dynamicliquid pressure oil, is controlled the forward and reverse motion and the movement velocity of a certain hydraulic actuator by electric ratio hydraulic valve and regulates; Select different hydraulic actuators by automatically controlled selector valve, realize the adjustment of different operating component function.
As shown in Figure 1, main control valve is made up of 2 oil-feed valve blocks, 2 electric proportional reversing valve valve blocks and 1 guide's oil sources valve block, and the oil-feed of 2 electric proportional reversing valves and work oil-out are independent, is equivalent to 2 simply connected electricity ratio commutation combination valves.The hydraulic oil of gear pump 14 can switch the flow direction of fluid through electric proportional reversing valve 5; Enter 4 automatically controlled selector valves 1,2,3 and 4; When control electronic operation handle 13 buttons made valve block 4 actions, hydraulic oil entered hydraulic jack or the hydraulic motor that is attached thereto through the actuator port C1/C2 of this valve block; When selecting another sheet valve events, hydraulic oil enters the hydraulic actuator that is attached thereto through the actuator port of this valve block; When selector valve 1,2,3,4 did not all move, hydraulic oil directly passed 4 automatically controlled selector valves, entered the hydraulic actuator of selecting valve block 1 cascade hydraulic fluid port B1/B2 to be connected.Controller connects control electromagnetic valve 6.
The control signal of electronic operation handle 12,13 is controlled 4 automatically controlled selector valves 1~4 and 8~11 respectively, and input controller 15.Controller is according to the electric proportional reversing valve of input signal export ratio signal controlling correspondence.When the electronic operation handle has compound button to press, controller is according to input signal and composite signals 2 electric proportional reversing valves 5 of export ratio signal controlling and 7 simultaneously, with functional part (as left side perching knife hoist cylinder and the right side perching knife hoist cylinder) action of simultaneously operating left and right sides appointment.
As shown in Figure 2, system's microcontroller receives left and right sides electronic operation handle command signal, output control left and right sides electric proportional valve, and, control 10 kinds of workpieces of land leveller respectively by hydraulic selector.Microcontroller is reserved with the CAN bus simultaneously, when land leveller is equipped with the intelligence control system (as engine control, gearshift control, automatic leveling etc.) of band CAN bus, native system can with land leveller other intelligence control system swap data and control instructions, guarantee complete machine control more freely, conveniently, improve the complete machine control performance.
