Description

Technical Field

[0001] The utility model relates to the technical field of roadbed stone washing and mud removal, in particular to a stone washing and mud removal device used for highway roadbed and pavement construction. Background Art

[0002] The roadbed is the foundation for supporting the road surface. It is a geotechnical structure formed by excavation or filling. The main function of the roadbed is to provide the necessary conditions for road paving, to bear the traffic load on the road surface, and to transfer and diffuse the load deep into the foundation. Sand and gravel are needed for roadbed filling, and there is often soil attached to the sand and gravel. The soil needs to be cleaned before filling to avoid affecting the filling effect.

[0003] The current method of washing and removing mud from sand and gravel used for roadbed filling is to use clean water sprayed from a water gun to wash the sand and gravel. The clean water after washing contains sludge and will be directly discharged as sewage, which will waste water resources. In addition, the sand and gravel piled together when cleaning the soil will affect the effect of water flow in washing the soil. Clean water from a fixed direction cannot wash all directions of the sand and gravel, which will lead to uneven soil cleaning and affect the mud removal effect. Utility Model Content

A driving motor 21 is provided at the upper end of the L-shaped support plate 22. The output end of the driving motor 21 is fixedly connected to the active rod 15.

[0025] Through the above structure, the driving mechanism drives the active rod 15 and the driven rod 20 to rotate, which can drive the bristles to rotate and scrub the sand and gravel in the cleaning chamber. How to achieve the flushing of sand and gravel, the specific structure is as follows:

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the box body 1 is provided with at least one and evenly arranged suction pipe 8 cooperating with the sewage discharge chamber 3, the sewage discharge chamber 3 is provided with a slope plate 7, which facilitates the sewage to flow to the bottom of the suction pipe 8 and be sucked by the suction pipe 8, the lower end of the suction pipe 8 is provided with a filter screen 9, and the filter screen 9 is a detachable structure, the box body 1 is provided with an opening and closing cover cooperating with the sewage discharge chamber 3, which is convenient for cleaning the sludge remaining in the sewage discharge chamber 3, the upper end of the suction pipe 8 is provided with a confluence pipe 10, and one side of the box body 1 is fixedly connected with a suction pump 1 whose input end is connected to the confluence pipe 10 1, the output end of the suction pump 11 is provided with a water spray pipe 12 connected to the top plate 4, the lower end of the top plate 4 is provided with at least one and evenly arranged water spray plates 27 matched with the cleaning chamber 2, the top plate 4 is provided with a shunt pipe connected to the water spray pipe 12 and the water spray plate 27, the suction pump 11 is provided with two input ends, one of which is connected to the confluence pipe 10, and the other input end is provided with a water source pipe 13, the water source pipe 13 is provided with a solenoid valve 14, the solenoid valve 14 is convenient for controlling the switch of the water source pipe 13 to avoid wasting water flow.

[0031] Then start flushing. Specifically, one end of the water source pipe is connected to clean water, and the suction pump is turned on to suck in the clean water and pressurize it. The pressurized clean water will be sprayed onto the sand and gravel in the cleaning chamber through the water spray pipe, the diversion pipe and the water spray plate. After a certain amount of clean water is input, the solenoid valve is closed, and the clean water after brushing will pass through the filter hole and flow into the sewage chamber. Under the action of the ramp plate, the sewage will flow to the bottom of the suction pipe, and the filter screen can block the sludge in the sewage. Then the suction pump cooperates with the suction pipe to spray the water in the sewage chamber into the cleaning chamber again. In this way, the sludge is blocked in the sewage chamber by the filter screen, and the water flow is repeatedly sprayed into the cleaning chamber. After flushing for a period of time, most of the sludge on the sand and gravel will be cleaned and removed, and then the solenoid valve is opened, and new clean water is sucked in and sprayed onto the sand and gravel for cleaning. Finally, the sealing plate can be pulled out to remove the sand and gravel.
