In view of above -mentioned technical scheme, the utility model discloses can realize before the leveler in, simultaneously, single the position in back make up simultaneously and install the electrohydraulic control who attaches additional to realize the leveler operation of can both being correlated with under multiple operating mode.
Description
Technical field
The utility model belongs to the attached field of hydraulic control of engineering machinery, specifically, particularly relates to a kind of land leveller three for land leveller and attaches electrohydraulic control system.
Background technology
Land leveller, in overall operation process, often can install multiple attaching additional and realize different additional functions.Additional attaches such as ejector dozer, ridge buster etc.Because existing land leveller structurally exists relevant restriction, cause land leveller can only increase two positions at most when overall operation simultaneously and attach device.
Summary of the invention
The purpose of this utility model is to provide a kind of land leveller three to attach electrohydraulic control system, it can realize single position before, during and after land leveller simultaneously and combine the electrichydraulic control installed additional and attach simultaneously, thus realizes land leveller can carry out relevant operation under various working.
For reaching above-mentioned technique effect, the utility model is achieved through the following technical solutions:
Land leveller three described in the utility model attaches electrohydraulic control system, comprise rear ridge buster oil cylinder, middle ridge buster oil cylinder, front ejector dozer oil cylinder, described rear ridge buster oil cylinder is connected with tubular type hydraulic lock by fluid pressure line, and described tubular type hydraulic lock is connected with two six electric change valves by fluid pressure line; Described middle ridge buster oil cylinder is connected with plate-type hydraulic lock by fluid pressure line, and plate-type hydraulic lock is connected with two six electric change valves by fluid pressure line; Described two six electric change valves are connected with left banked direction control valves by fluid pressure line, and left banked direction control valves is connected with left hydraulic pump by fluid pressure line; Described front ejector dozer oil cylinder is connected with right banked direction control valves by fluid pressure line, and described right banked direction control valves is connected with right hydraulic pump.
Compared with prior art, the utility model has following beneficial effect:
1, the utility model can realize single position before, during and after land leveller simultaneously and combine the electrichydraulic control installed additional and attach simultaneously, thus realizes land leveller can carry out relevant operation under various working.
2, control system of the present utility model has the advantages that control mode is simple, reliability is high, easy for installation, and compliance is high, possesses the value promoted the use of.
Accompanying drawing explanation
Fig. 1 is principle schematic of the present utility model.
In figure: 1, rear ridge buster oil cylinder; 2, middle ridge buster oil cylinder; 3, front ejector dozer oil cylinder; 4, tubular type hydraulic lock; 5, plate-type hydraulic lock; 6, two six electric change valves; 7, left banked direction control valves; 8, right banked direction control valves; 9, left hydraulic pump; 10, right hydraulic pump.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1: a kind of land leveller three attaches electrohydraulic control system, comprise rear ridge buster oil cylinder 1, middle ridge buster oil cylinder 2, front ejector dozer oil cylinder 3, described rear ridge buster oil cylinder 1 is connected with tubular type hydraulic lock 4 by fluid pressure line, and described tubular type hydraulic lock 4 is connected with two six electric change valves 6 by fluid pressure line; Described middle ridge buster oil cylinder 2 is connected with plate-type hydraulic lock 5 by fluid pressure line, and plate-type hydraulic lock 5 is connected with two six electric change valves 6 by fluid pressure line; Described two six electric change valves 6 are connected with left banked direction control valves 7 by fluid pressure line, and left banked direction control valves 7 is connected with left hydraulic pump 9 by fluid pressure line; Described front ejector dozer oil cylinder 3 is connected with right banked direction control valves 8 by fluid pressure line, and described right banked direction control valves 8 is connected with right hydraulic pump 10.
In conjunction with above-described embodiment, the utility model in use, if when land leveller needs to carry out bulldozing or loosening the soil in front end, right banked direction control valves 8 is controlled by control crank, power is provided by right hydraulic pump 10, and then ejector dozer oil cylinder 3 before controlling, then drive ejector dozer or front ridge buster etc. to attach by front ejector dozer oil cylinder 3 to carry out relevant operating mode operation.
When land leveller needs to loosen the soil before the smooth operating mode of perching knife, two six electric change valves 6 are charged, left banked direction control valves 7 is controlled by control crank, power is provided by left hydraulic pump 9, and then ridge buster oil cylinder 2 in being controlled by plate-type hydraulic lock 5, then in being driven by middle ridge buster oil cylinder 2, ridge buster etc. attaches and carries out relevant operating mode operation.
When land leveller needs after the smooth operating mode of perching knife, and then when loosening the soil in trailing wheel place, two six electric change valves 6 are not charged, left banked direction control valves 7 is controlled by control crank, power is provided by left hydraulic pump 9, and then control rear ridge buster oil cylinder 1 by tubular type hydraulic lock 4, then drive rear ridge buster or rear shank etc. to attach by rear ridge buster oil cylinder 1 to carry out relevant operating mode operation.
