Specific embodiment
In order to make those skilled in the art better understand the technical solutions in the application, below in conjunction with the application reality
The attached drawing in example is applied, the technical scheme in the embodiment of the application is clearly and completely described, it is clear that described implementation
Example is merely a part but not all of the embodiments of the present application.Based on the embodiment in the application, this field is common
The application protection all should belong in technical staff's every other embodiment obtained without making creative work
Range.
As Figure 1-Figure 2, the technical solution that present embodiment provides is as follows:
A kind of pump truck cleaning device, the flushing pump 4 in 1 outside of hopper side wall including being set to pump truck, the outlet of the flushing pump 4
Pipe 3 passes through hopper side wall 1, and towards the inside of hopper side wall 1, the outlet 3 is equipped with and is hinged on hopper side wall 1 and is used for
The cover board 2 of outlet 3 is covered, the cover board 2 is equipped with for making cover board closely cover the elastic device 5 of outlet 3.
The course of work of present embodiment is as follows:
Pump truck work when, cover board 2 by elastic device 5 pulling force and only cover outlet 3.After pump truck has worked
When needing to rinse, flushing pump 4 is opened, after hydraulic pressure overcomes the pulling force of elastic device 5, is entered in the hopper 10 of pump truck, it is right
Inside is rinsed, and closes flushing pump 4 after the completion of rinsing.
Flushing pump 4 in present embodiment can be using flush water pump common on the market.Elastic device 5 can be adopted
With spring, compressed spring or torque spring is drawn high, can apply pressure on cover board 2 makes it be close to outlet 3.Flushing pump
4 unlatching can be controlled with hand push button, can also with pump truck linkage control, both when pump truck work after the completion of auto-flushing.It rinses
The water source of pump 4 can be derived from external water tank, or be derived from the water tank carried on pump truck.
In order to enhance leakproofness, gasket, sealing ring can be set between cover board 2 and outlet 3.
Present embodiment not only may be mounted on new pump truck, and can also punch on the hopper of existing pump truck can pacify
Dress, good compatibility.The present invention can open flushing pump when needing to rinse by hinged cover board 2 and elastic device 5
4, after hydraulic pressure overcomes the power of elastic device 5, hopper 10 and pipeline are rinsed.When in non-washed situation, pump truck work
In the case where, the outlet 3 of flushing pump 4 is sealed, to prevent concrete from entering in flushing pump 4.Using the present invention, can pump
Turner is in time rinsed hopper and conveyance conduit after the completion of making, and prevents influence of the solid concrete to conveying inside pipe wall,
The service life of extended delivery pipe.Delivery pipe cleans out the conveying that can be conducive to concrete in time, increases delivery pipe
Cross-sectional area improves transfer efficiency, reduces the failure rate and oil consumption of board.
It can also include the fixed link 6 being set in outlet 3, the bullet as the further preferred of present embodiment
Property device 5 be extension spring, one end of extension spring connect with cover board 2, and the other end is connect with fixed link 6, so that 2 tension of cover board
It stretches acting force of the spring and closely covers outlet 3.When rinsing, after hydraulic pressure overcomes the pulling force of extension spring, cover board is opened
2, it is rinsed.After the completion of flushing, close flushing pump 4, hydraulic pressure reduces and disappears, the pulling force of 2 Tensile spring of cover board and answer
Position.
Certainly, elastic device 5 or the torsion bullet being arranged on cover board 2 and the hinged hinging pin shaft of hopper side wall 1
Spring, so that cover board 2 is closely covered outlet 3 by torque spring active force.When rinsing, hydraulic pressure overcomes torque spring
After pulling force, cover board 2 is opened, is rinsed.After the completion of flushing, flushing pump 4 is closed, hydraulic pressure is reduced and disappeared, and cover board 2 is by torsion
The torsion of spring and reset.
As the further preferred of present embodiment, non-return valve 7 can also be set between outlet 3 and flushing pump 4, used
In further preventing the muddy water in pump truck, liquid, concrete to flow backwards, security performance and sealing performance are enhanced.
As the further preferred of present embodiment, the water inlet of flushing pump 4 is connected to support leg of pump truck water tank 8, facilitates water intaking.
In a practical situation, in addition water tank can also be set, or take the water source near pump truck.
As the further preferred of present embodiment, the hopper side wall 1 is hopper rear wall.Setting is more conducive at rear
Installation, and it is beautiful, the normal work of pump truck will not be interfered.
As the further preferred of present embodiment, the flushing pump 4 is connected with hydraulic motor 11, and hydraulic motor 11 connects
There is the control device 9 for controlling hydraulic conveying.It is hydraulic to reach control for switching or being connected to hydraulic pipeline for control device 9
The purpose of the work of motor.
Further, the control device 9 includes the control valve of connection liquid conducting pipes.Control valve can be manually
Operation, cutting or connection hydraulic pipeline, can also with electronic operation.
Further, the control valve is solenoid electric valve.Hydraulic pipeline is communicated to the hydraulic system of pump truck, and electromagnetism
Valve is then connected with the electric system of pump truck.
The present invention also provides a kind of pump truck, the cleaning device including above-mentioned any one.Pass through hinged cover board and elasticity
Device can open flushing pump, after hydraulic pressure overcomes the power of elastic device, to hopper 10 and pipeline when needing to rinse
It is rinsed.In non-washed situation, in the case where pump truck work, the outlet 3 of flushing pump 4 is sealed, to prevent coagulation
Soil enters in flushing pump 4.Using the present invention, hopper 10 and conveyance conduit can be rushed in time after the completion of pump truck works
It washes, prevents influence of the solid concrete to conveying inside pipe wall, the service life of extended delivery pipe.Delivery pipe is cleared up dry in time
Net energy is conducive to the conveying of concrete, increases the cross-sectional area of delivery pipe, improves transfer efficiency, reduces the failure rate of board
And oil consumption.
