Technical field
The utility model relates to electromagnetic reversing arrangement, more particularly especially is applied in the electromagnetic reversing arrangement on the solenoid electric valve in the semi-feeding type rice harvester.
Background technique
The structural type of the solenoid electric valve that uses in the semi-feeding type rice harvester that adopts is at present: a 3-position 4-way solenoid directional control valve control hydraulic steering system; Two four-way electromagnetic reversing valves control ceding of Taiwan elevator system and a two-position two-way solenoid valve control ceding of Taiwan decline system.These three solenoid valves are integrated on the control valve piece.What the 3-position 4-way solenoid directional control valve on the solenoid electric valve was selected for use is to realize function by two general electromagnet, and what two four-way electromagnetic reversing valves were selected for use is to realize function by a general electromagnet.Because this general electromagnet can only provide the action of a direction, even push away or draw, therefore, for for realizing that various functions need the reaper of a plurality of solenoid valves of corresponding outfit, the outfit complexity of electromagnetic mechanism, and volume is bigger, simultaneously do not have waterproof and dust-tight function, working environment is had relatively high expectations, be applied under the wet environment of semi-feeding type rice harvesting because of it, very easily cause electromagnetic coil to be blown, rate of fault is higher.
The model utility content
The utility model is for avoiding above-mentioned existing in prior technology deficiency, provides that a kind of electromagnetic mechanism is simple in structure, encapsulation good, waterproof dust-tight is applied in the electromagnetic reversing arrangement in the solenoid electric valve, to reduce rate of fault, improves functional reliability.
The utility model technical solution problem adopts following technological scheme;
Agent structure of the present utility model comprises the valve body that is provided with valve pocket, is positioned at valve pocket guiding valve in axial sliding, corresponding to each hydraulic fluid port of diverse location relative set of guiding valve, and can drive the axially movable electromagnetic mechanism of guiding valve on the valve body;
Structural feature of the present utility model is, electromagnetic mechanism is single-ended setting, single-ended setting is a termination at guiding valve, connect firmly with guiding valve by straight pin and to be in guide rod on the coaxial position, with the guide rod is the Electromagnetic Drive bar, the electromagnetic coil of relative set is two groups of reverse coiling each other, and two groups of electromagnetic coils are drawn the winding end line separately.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
Electromagnetic mechanism of the present utility model is single-ended setting, two actions can be realized pushing away, be drawn to the Electromagnetic Drive bar of single-ended setting respectively, to need focus on by the function that two groups of electromagnetic mechanisms are finished on one group of electromagnetic mechanism of single-ended setting originally, and make the profile of solenoid electric valve compact, attractive in appearance more; Simultaneously, because single-ended setting can be carried out the setting of waterproof and dustproof function easily, effectively improve functional reliability.

Embodiment
Referring to Fig. 1, agent structure comprises the valve body 2 that is provided with valve pocket, is positioned at valve pocket guiding valve 4 in axial sliding, corresponding to each hydraulic fluid port of diverse location relative set of guiding valve 4, and can drive guiding valve 4 axially movable electromagnetic mechanisms on the valve body 2.
Shown in Fig. 1 and Fig. 2 (a), in the present embodiment, electromagnetic mechanism is single-ended setting, specifically being a termination at guiding valve 4, connecting firmly with guiding valve 4 by straight pin 9 and be in guide rod 11 on the coaxial position, is the Electromagnetic Drive bar with guide rod 11, the electromagnetic coil 13 of relative set is two groups of reverse coiling each other, two groups of electromagnetic coils 13 are drawn the winding end line separately, and shown in Fig. 2 (b), the winding end line of drawing is respectively end line A, end line B, end line C and end line D.
Present embodiment is the 3-position 4-way solenoid directional control valve, and its structural type and working method are:
State shown in Figure 1 is that two groups of electromagnetic coils all must not be electric, and the 3-position 4-way solenoid directional control valve of this moment is in the neutral position.Guiding valve 4 and guide rod 11 are connected by straight pin 9; spring seat 8 is positioned on the valve body 2, and compression spring 12 is positioned on the guide rod 11, is supported by spring 10 between them; guiding valve 4 abuts against on the spring seat 8 it by guide rod 11 and spring 10 actings in conjunction, and the neutral position of guaranteeing guiding valve 4 is unique.Return opening 3, left side actuator port 5, right side actuator port 7 and filler opening 6 all are communicated with at this moment, and according to the difference of guiding valve 4 structures, the mode of communicating of each hydraulic fluid port can change.
Shown in Fig. 2 (b), the winding end line that two groups of electromagnetic coils are drawn separately is respectively end line A and end line B, and end line C and end line D, because the coiling direction of two groups of electromagnetic coils is opposite, therefore, when one group of coil electricity wherein, the active force that moves right is provided for guide rod 11; When another group wherein during coil electricity, active force to left movement is provided then for guide rod 11, in concrete the enforcement, the coil interface place of four leading-out end line should adopt plastic packaging.
Shown in Figure 3, get electricly as one group of coil, guide rod 11 obtains the active force to left movement, drives guiding valves 4 and compression spring 12 is moved to the left 2mm to working state shown in Figure 3 by guide rod 11.This moment, filler opening 6 and left side actuator port 5 were communicated with, and return opening 3 and right side actuator port 7 are communicated with.Compression spring 12 is being moved to the left 2mm simultaneously, and spring 10 is compressed 2mm.In case the coil working electric current is cut off, coil disappears for the active force to left movement on the guide rod 11 thereupon, promotes under the effect of compression spring 12 restoring force to the right at spring 10, and guide rod 11 drives guiding valve 4 and gets back to position shown in Figure 1.
Shown in Figure 4, when another group coil gets electricly, guide rod 11 obtains an active force that moves right, drive guiding valves 4 2mm that moves right by guide rod 11, guiding valve 4 drives spring seats 8 2mm that moves right, and spring seat 8 makes spring 10 be compressed 2mm simultaneously, and guiding valve 4 is in another working state shown in Figure 4.At this moment, filler opening 6 and right side actuator port 7 are communicated with, and return opening 3 and left side actuator port 5 are communicated with.In case the coil working electric current is cut off, coil disappears for the active force that moves right on the guide rod 11 thereupon, promotes under the active force of spring seat 8 restoring force left at spring 10, and spring seat 8 drives guiding valve 4 and gets back to position shown in Figure 1.
The effect of manual button 1 in left side and the manual button 14 in right side is when not having power supply, can carry out work by manual button 1 in direct manipulation left side and the moving button 14 of the right hand.
