Abstract
The utility model discloses an electrohydraulic control combination valve for a harvester, which comprises a valve body. The valve body is provided with a pump oil inlet and an oil return opening, two steering oil cylinder oil inlet connectors and a header oil cylinder connector. A three-position four-way solenoid valve, a two-position four-way solenoid valve and a thread solenoid valve are spirally connected with the valve body; the oil inlet of the two-position four-way solenoid valve is communicated with the pump oil inlet; and the three-position four-way solenoid valve is communicated with the two steering oil cylinder oil inlet connectors. The combination valve is comparatively easy to process; because various standards of valves are adopted to replace the original slide valves, the processing difficulty is lower and short working hours are consumed; moreover, standard components are adopted, therefore, the universality is high and the degree of automation is high; because the valves of controlling a header to rise or fall and turn are the solenoid valves, the valves can be connected with an electrical control system of the whole harvester together and people do not need to carry out manual operations. The development trend of the traditional harvester is met and the labor strength of an operator is also relieved.

Embodiment:
The following stated is preferred embodiment of the present utility model only, is not that scope of the present utility model is limited.
Embodiment sees accompanying drawing 1～6; A kind of reaper electrichydraulic control combination valve, comprise valve body 1, have on the valve body pump filler opening 101, return opening 102, two turn to oil cylinder oil-feed interface 103,104 and ceding of Taiwan oil cylinder interface 105, three position four-way electromagnetic valve 2, two-position four-way solenoid valve 3 and screw thread solenoid valve 4 are spirally connected on the valve body 1, the oil inlet P of described two position four-way solenoid valves and pump filler opening 101 are connected, and described three position four-way electromagnetic valve 2 and two turn to oil cylinder oil-feed interface to be communicated with; Two of two-position four-way solenoid valve 3 carrying out hydraulic fluid port A, B is communicated with filler opening, the ceding of Taiwan oil cylinder interface of three position four-way electromagnetic valve 2 respectively.By the switching of two-position four-way solenoid valve, can control the UNICOM of the high pressure oil of coming in from the pump filler opening and three position four-way electromagnetic valve, taiwan cut off and landing oil cylinder interface, and then control taiwan cut off and landing oil cylinder and the ceding of Taiwan turn to the work of oil cylinder.On valve body 1, also have a ceding of Taiwan relief valve 5 and one to turn to relief valve 6; ceding of Taiwan relief valve and pump filler opening are communicated with; pressure when being used for controlling the work of taiwan cut off and landing oil cylinder; and the working pressure when turning to relief valve to be used for controlling the steering oil cylinder working; two relief valves all are the effects of playing overflow, protection in superpressure, and it is dangerous to prevent that overpressure from producing.
Also be fixed with one and the manual throttle valve 7 that is communicated with of return opening 102 on the described valve body 1, this manual throttle valve have one with the oil return interface 702 that turns to the oil cylinder return opening to be connected.This manual throttle valve comprises a throttle valve body 701, and a spool chamber is arranged in throttle valve body, and this spool chamber and oil return interface communicate, one regulating spool 703 is installed in spool chamber, and this regulating spool part is exposed at the valve body outside, is used for the manual tune flow, play the effect of throttling
Be provided with oil-feed filter screen 8 in the described pump filler opening.This filter screen will filter from the hydraulic oil that the pump filler opening is come in, and gets rid of the pollutant in the fluid, with the proper functioning of protection hydraulic pressure components and parts.
Be provided with filter screen 9 in the described ceding of Taiwan oil cylinder interface, a damping 10 is arranged between ceding of Taiwan oil cylinder interface and screw thread solenoid valve.Filter screen can be with fluid filtering again, guarantees to enter the turbidity test of the hydraulic oil of ceding of Taiwan oil cylinder to greatest extent, and damping then can be played the effect of throttle valve.
Between described two-position four-way solenoid valve and the ceding of Taiwan oil cylinder interface one-way valve 11 is arranged.This one-way valve makes hydraulic oil liquid to flow to the taiwan cut off and landing oil cylinder from two position four-way solenoid valves, the hydraulic oil of taiwan cut off and landing oil cylinder can only pass through the off-load of screw thread solenoid valve, and can not reverse flow, one-way valve comprises valve core case 1101, steel ball 1102, spring seat 1103 and the spring 1104 that is installed in the valve body spool chamber, spring is installed in valve body and is spirally connected in the fixing plug screw 1105, plug screw is provided with sealing gasket, is used for sealing, and prevents leakage of oil.
Working principle: in work, the hydraulic oil that comes out from oil pump is through the pump filler opening on the valve body, through entering the pipeline of valve body behind the oil-feed strainer filtering,, arrive three position four-way electromagnetic valve through behind the two-position four-way solenoid valve, turn to oil cylinder oil-feed interface to arrive through two then and turn to oil cylinder 13, carry out work, the manually operated type throttle valve is connected on and turns on the oil cylinder return line, can play hold back, the effect of back pressure, can control the speed when turning to oil cylinder to return, play the effect of buffering; Turn to relief valve when reaper uses metering pump, can play the effect of control steering oil cylinder working pressure, when using variable displacement pump, can play the effect of safety valve, prevent unexpected the generation; The electromagnet of two-position four-way solenoid valve gets electric, and solenoid valve switches, and the hydraulic oil of coming in from the pump filler opening backs down one-way valve, enters taiwan cut off and landing oil cylinder 12 through the filter screen filter screen; The screw thread solenoid valve is used for playing the effect of off-load when the taiwan cut off and landing oil cylinder is fallen, and the effect of throttling, buffering is played in damping, and it is more steady to make that the ceding of Taiwan descends.
