Abstract
The utility model relates to a debunker two-way synchronous control system used for a paddy rice reaping machine. The utility model is characterized in that a synchronous control two-way output is arranged in parallel in a main oil way controlled by an operating valve, the synchronous control two-way output adopts the structure that a branch locking control one-way valve is respectively arranged in each output branch composed of a branch oil cylinder and a branch debunker, a locking control structure is positioned towards the direction of the main oil way of the locking control one-way valve in the branch oil cylinder, and a normal open structure is positioned towards the direction branch oil cylinder in the main oil way, and corresponding to the center position of the operating valve during the debunking, the locking control one-way valves in the two branches are in the one-way locking state.
Description
Technical field:
The utility model relates to the rice harvester debanker, more specifically says so to be used to control the hydraulic control system of rice harvester debanker synchronous working.
Background technology:
In the prior art, be equipped with debanker the paddy rice harvesting machine hydraulic system version as shown in Figure 1, left side road debanker 1 and right wing debanker 2 are to utilize same working connection 3 to control its one-way cylinder separately respectively, the oil circuit that is left road binders cylinder 4 and 5, two one-way cylinders of right wing oil cylinder is ganged up.During debanker work, control valve 6 is in the neutral position; The commutation of control valve 6 can make debanker rise or descend.
But in actual use, two debankers probability of touching ridge simultaneously is little.If, left side road debanker 1 at first contacts ridge, and begin brokenly the ridge, and right wing debanker 2 does not temporarily also touch ridge, at this moment, ridge has formed reaction force to left road debanker 1, piston in the left road binders cylinder 4 is pulled outwardly to be stretched, oil pressure in the left side road binders cylinder 1 raises, because two one-way cylinder oil circuits are ganged up, therefore, the rising of left road binders cylinder 1 oil pressure will make the piston in the right wing oil cylinder 2 move inward by the working connection 3 with its intercommunication, meanwhile, by piston rod right wing debanker 2 is come back.When right wing debanker 2 touched ridge, it highly was lifted, and caused left road debanker 1 inconsistent with the broken ridge height of right wing debanker 2.
Summary of the invention:
The utility model is for avoiding above-mentioned existing in prior technology weak point, the control lock that a kind of rice harvester debanker two-way synchronous control system is provided and realizes the two-way Synchronization Control.
The technical scheme that the utility model technical solution problem is adopted is:
The design feature of the utility model rice harvester debanker two-way synchronous control system is in the working connection by control valve control, be arranged in parallel the output of Synchronization Control two-way, described Synchronization Control two-way output is in every the output branch road that is made of branch road oil cylinder and branch road debanker, branch road lock control check valve is set respectively, described lock control check valve is the lock control structure at the branch road oil cylinder towards the working connection direction, is the normal open structure at working connection towards branch road oil cylinder direction; Lock control check valve in the neutral position of control valve during corresponding to the broken ridge, two branch roads is unidirectional locking states.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, the utility model is provided with the lock control check valve, when the operation of the broken ridge, with the oily passage that cuts off between two branch roads of closing of check valve, avoids string oil between two oil cylinders, has kept broken ridge height unified between the two-way debanker.
2, the utility model is simple in structure, easy to implement, directly utilizes the output of control valve control port can realize the in good time lock control of lock control check valve.
Description of drawings:
Fig. 1 is the prior art structural representation.
Fig. 2 is the utility model structural representation.
Fig. 3 is the utility model lock control one-way valve structures schematic diagram.
Fig. 4 is the C-C sectional structure schematic diagram of Fig. 3.
Number in the figure: 1 left road debanker, 2 right wing debankers, 3 working connections, 4 left road binders cylinders, 5 right wing oil cylinders, 6 control valves, 7 left road lock control check valves, 8 right wing lock control check valves, 9 left oil ducts, 10 right oil ducts, 11 spools, 12 control oil circuits, 13 lock control valve rods, A actuator port, A1 left side road binders cylinder hydraulic fluid port, A2 right wing oil cylinder hydraulic fluid port, B control port.
Below pass through embodiment, and in conjunction with the accompanying drawings the utility model is further described.
Embodiment:
Referring to Fig. 2, in working connection 3, be arranged in parallel the output of Synchronization Control two-way by control valve 6 controls, comprise, by the left road output that left road debanker 1 and left road binders cylinder 4 constitute, export by the right wing that right wing debanker 2 and right wing oil cylinder 5 constitute.
In the present embodiment, article two, in the output branch road, branch road lock control check valve is set respectively, be left road lock control check valve 7 and the right wing lock control check valve 8 shown in Fig. 2, this lock control check valve is the lock control structure at the branch road oil cylinder on the direction of working connection, be the normal open structure on the direction of branch road oil cylinder at working connection; Lock control check valve in the neutral position of control valve 6 during corresponding to the broken ridge, two branch roads is unidirectional locking states.
Under the duty of the broken ridge, control valve 6 is in the neutral position, and left road lock control check valve 7 and right wing lock control check valve 8 are unidirectional locking states.At this moment, if there is left road debanker 1 to touch ridge in advance, and begin brokenly the ridge, then left road binders cylinder 4 is subjected to the external force effect, because the hydraulic fluid port of left road binders cylinder 4 and right wing oil cylinder 5 is respectively by left road lock control check valve 7 and right wing lock control check valve 8 lockings, thereby be separated each other and can not form string oil, with this oil pressure that has not only kept the two-way oil cylinder, also kept the identical broken ridge height of two-way debanker.
In actual the controlling, because the lock control check valve is the normal open structure on the direction of branch road oil cylinder at working connection, therefore, debanker is non-identical with working method shown in Figure 1 with the lifting under the state.
Have only when needs put down debanker, by hydraulic fluid port B on the driven valve 6 unlatching, open the unidirectional same valve of two-way lock control, make it be conducting state, the hydraulic oil in the two-way oil cylinder is by the working connection oil return.
The structure setting of lock control check valve is specially:
Shown in Figure 3, shown in Figure 4, the actuator port A of driven valve 6 is divided into two-way by left oil duct 9 and right oil duct 10, and respectively by the lock control check valve spool 11 in the oil circuit separately unidirectional straight-through to forming between left road binders cylinder hydraulic fluid port A1 and the right wing oil cylinder hydraulic fluid port A2 from actuator port A; The control port B of control valve 6 in symmetrically arranged two lock control valve rods 13, and forms the releases promotions by 13 pairs of spools of lock control valve rod 11 through control oil circuit 12 two-way functions, thereby opens the lock control check valve, makes it be the two-way admittance state.
