Abstract
The utility model relates to the connection mode of a hydraulic distributor used for a tractor, which is simple in structure and long in service life. Due to the adoption of the connection mode, the deformation of a hydraulic distributor and the valve blockage do not easily happen and the hydraulic distributor can be conveniently repaired. The connection mode of a hydraulic distributor comprises a distributor, an oil cylinder and a connection plate. The oil cylinder is provided with an oil inlet hole. The distributor comprises a housing and a one-way valve. The housing of the distributor is fixedly connected with the oil cylinder through the connection plate. The connection plate is provided with an oil guide hole. The oil outlet of the one-way valve is communicated with one end port of the oil guide hole of the connection plate. The other end port of the oil guide hole is communicated with the oil inlet hole of the oil cylinder.
Description
Technical field
The utility model relates to a kind of farm machinery pressure distributor, particularly relates to a kind of pressure distributor Placement that is used for tractor.
Background technique
In recent years; Quickening along with tractor manufacturing, development progress; The client is also more strict to its performance demands, and the distributor that constitutes one of its critical component is the core of tractor hydraulic control, and the quality of its performance is directly determining the quality of whole tractor hydraulic suspension system performance.Extremely shown in Figure 3 like Fig. 1; The pressure distributor 1 ' of tractor is made up of several major parts such as distributor body 10 ', main control valve 4 ', scavenger valve 5 ', one-way valve 6 ', rate of descent modulating valve 9 ', and lifting, neutrality, three kinds of working staties of decline are arranged, and distributor 1 ' major failure in the course of the work is that card valve phenomenon can take place; Particularly along with the lifting of tractor power; The main pump fuel delivery strengthens, and system pressure increases, and main control valve 4 ' waits the rate of fault of card valve higher with scavenger valve 5 '; In use and maintenance process, find; The Placement of distributor 1 ' is the one of the main reasons that causes card valve phenomenon, traditional distributor Placement be housing 10 ' with distributor 1 ' with three bolts, 3 ' fastening being installed on the oil cylinder 2 ', the oil outlet of distributor 1 ' internal check valve 6 ' directly is connected with the oil inlet hole of oil cylinder 2 '; Yet in this Placement; The clamping force of bolt 3 ' can make distributor body 10 ' distortion, and the main control valve 4 ' in the distributor body 10 ' waits with scavenger valve 5 ' and also can be out of shape owing to the clamping force of bolt 3 ', so card valve fault will often occur; In addition; Also there is the another one shortcoming in this Placement; That is: this distributor 1 ' adopts bolt 3 ' ways of connecting with cylinder body 2 ', makes that at distributor 1 ' maintenance man need take out with cylinder body 2 ' distributor 1 ' in the lifter housing when the faults such as card valve that main control valve 4 ' and scavenger valve 5 ' occur need repairing; And then distributor 1 ' unloaded very inconvenience from cylinder body 2 '.
The model utility content
In order to solve the problems of the technologies described above; The utility model provides a kind of simple in structure, long service life, make the not yielding card valve of distributor, pressure distributor Placement easy to maintenance, and the pressure distributor Placement of the utility model can be widely used in the distributor of big or middle power tractor.
A kind of pressure distributor Placement of the utility model; Comprise distributor, oil cylinder and connecting plate, offer oil inlet hole on the oil cylinder, distributor comprises housing and one-way valve; The housing of said distributor is fixedly connected with oil cylinder through connecting plate; Offer oil guiding hole on the connecting plate, a port of oil guiding hole is connected on the oil outlet of said one-way valve and the connecting plate, and the another port of oil guiding hole is connected with oil inlet hole on the oil cylinder.
The utility model difference from prior art exists: a kind of pressure distributor Placement of the utility model; Between distributor body and oil cylinder, set up connecting plate; Through connecting plate distributor body is linked to each other with oil cylinder; Oil outlet with the distributor internal check valve is connected with cylinder cavity through the oil guiding hole that is opened on the connecting plate simultaneously, avoided directly distributor body and oil cylinder being compressed the card valve fault that links to each other and cause with bolt in the existing technology, and owing to adopt the connecting plate ways of connecting; In case certain parts breaks down in the distributor; Only distributor is pulled down the taking-up maintenance from connecting plate and get final product, and will not take out together with oil cylinder by distributor, maintenance operation is convenient.
Be described further below in conjunction with the pressure distributor Placement of accompanying drawing the utility model.

Embodiment
Extremely shown in Figure 6 like Fig. 4; The utility model pressure distributor Placement comprises distributor 1, oil cylinder 2 and connecting plate 3, offers oil inlet hole on the oil cylinder 2; Distributor 1 comprises housing 10, main control valve 4, scavenger valve 5, one-way valve 6 and rate of descent modulating valve 9; The housing 10 of distributor 1 is connected with oil cylinder 2 through connecting plate 3, compresses through seal washer, bolt between housing 10 and the connecting plate 3 and between connecting plate 3 and the oil cylinder 2 to be connected, and offers oil guiding hole 7 on the connecting plate 3; A port of oil guiding hole 7 is connected on the oil outlet of one-way valve 6 and the connecting plate 3, and the another port of oil guiding hole 7 is connected with oil inlet hole on the oil cylinder 2.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technological scheme of the utility model all should fall in the definite protection domain of the utility model claims.
