Technical field
The present invention relates to a kind of slurry casting machine more particularly to a kind of railway cement prefabricated component slurry casting machines.
Background technique
When carrying out cement prefabricated component processing, people need the concrete being stirred being filled into concrete prefabricated structure people
In the molding equipment of part, the amount of the concrete as needed for cement prefabricated component is smaller, and large-scale concrete transporting equipment makes
Used time, waste is more serious, while place needed for larger transport devices is also larger, and small device has mobile inconvenient ask
Topic, people are usually to fill using by the way of artificial promotion small handcart at present, fill in this way it is more convenient, while also can be most
It avoids wasting to limits, but people can be relatively more arduous, working efficiency is not also high;People be usually after concrete has filled,
It reuses the equipment with vibrator to be vibrated, will affect tamping for concrete in this way, time of vibration can be longer.
Summary of the invention
In order to overcome current people to exist when carrying out filling concrete manually, filling, inefficient and time of vibration are longer
The shortcomings that, technical problem are as follows: provide it is a kind of with filing provision, more efficient and shorter time of vibration railway is with concrete prefabricated
Component slurry casting machine.
Technical solution are as follows: a kind of railway cement prefabricated component slurry casting machine, include vehicle frame, the first wheel, the second wheel,

When people need to carry out slip casting, people first pass through filler pipe and concrete are injected into cabinet, and then people open
Dynamic driving mechanism work, and then the movement of the second wheel is driven by first rotating shaft, and drive vehicle frame and the first wheel mobile, simultaneously
Driving mechanism will drive first bevel gear rotation, and then drive the second shaft, second bevel gear, third hand tap gear and the 4th cone tooth
Wheel rotation then drives third shaft and blade rotation, so as to constantly push the intracorporal concrete of case to the right, just
In the blanking of concrete, concrete will not be made to be deposited in cabinet, and the cleaning to people is made troubles, it is pre- when being moved to cement
When at the molding equipment of component processed, people open valve, and then the intracorporal concrete of case is discharged from discharge nozzle, then make coagulation
Soil drops into the molding equipment of cement prefabricated component, and with the movement of the second wheel and the first wheel, concrete can will be formed
Equipment fills, and after people fill molding equipment, people close valve, then the present invention is moved to next concrete prefabricated structure
Filling concrete is carried out at the molding equipment of part, after people have filled molding equipment, the present invention is moved to original again by people
Position, is then shut off driving mechanism, and then the first wheel and the second wheel is made to stop movement, and blade stops operating, drive of the invention
Motivation structure can drive the first wheel and the second wheel to be moved, and concrete is moved and filled convenient for people, be not required to people again
Work is pushed, and is saved the physical strength of people, is improved work efficiency.
When people, which need, keeps the second wheel mobile, people start dual-axle motor work, the rotation of dual-axle motor output shaft
The second sprocket wheel and chain is driven to rotate, the rotation of the first sprocket wheel of chain-driving, and then first rotating shaft and the second vehicle wheel rotation are driven, from
And the present invention can be moved, while the rotation of dual-axle motor output shaft will drive first bevel gear rotation, and then with movable vane
Piece rotation, after people's use, people turn off dual-axle motor, and then the second wheel is made to stop operating, and blade stops turning
It is dynamic.
When people need to pick and place thing from bottom of box gap, people first pass through swing handle and open chamber door, so
People again turn over to the right chamber door afterwards, and after inserted block is inserted into fixture block, the position of chamber door can be fixed for fixture block, then people
Hand can be unclamped, no longer carry out stirring chamber door, after people pick and place, people stir chamber door to the left again, and then make inserted block
It is extracted out of fixture block, then chamber door can be put back to original position by people, and after chamber door resets, people are rotated further by handle, and then by case
Door is lockked, and prevents chamber door opening, left and right that the effect of hinge is easy for chamber door when the present invention is mobile from stirring, chamber door can be prevented
Only the thing of the inside is fallen, and avoids the pickup of people.
When people need to vibrate concrete, people first open chamber door, then take out vibrating head, restart vibration
Dynamic device work, and then vibrating head can be extend into molding equipment inner concrete and be vibrated, so as to fill out concrete more
It enriches, helps to improve the quality of cement prefabricated component, when vibrating tube falls short of, people are pulled along slide bar and pull ring, into
And vibrating tube can be forward extended out, when people after use, people move backward back slide bar and pull ring in situ, turn off vibration
Device, and vibrating head is put back into original position, it can so be vibrated while people fill concrete, it is easier to by concrete
It tamps, the time of vibration also can be shorter, while vibrator is located in the present invention and preferably can carry out storing using vehicle frame, makes vehicle frame
Effect obtained preferably playing.
Have the beneficial effect that the present invention can drive the first wheel and the second wheel to be moved by the driving mechanism of setting,
Concrete is moved and filled convenient for people, is not required to manually be pushed again, saves the physical strength of people, improves work effect
Rate;It can be vibrated while people fill concrete by the vibrator of setting, it is easier to concrete is tamped, vibration
Time also can be shorter, helps to improve the quality of cement prefabricated component, while vibrator is located in the present invention and can preferably utilize
Vehicle frame carries out storing, and the effect of vehicle frame is made to have obtained preferably playing.
