The utility model provides a road is sewage suction nozzle device for cleaning vehicle, its compact structure can prevent that big rubbish from inhaling, prevents to block up, convenient popularization.
In order to achieve the above object, the utility model adopts the following technical scheme:
the utility model provides a sewage suction nozzle device for road cleaning vehicle, includes water sucking mouth, rose box structure and the sewage pipe of being connected with sewage collecting box, the one end and the sealed fixed connection of sewage pipe of rose box structure, the other end is connected with the water sucking mouth, the inside of rose box structure is fixed and is equipped with first filter screen and the second filter screen that sets up with the laminating of first filter screen, the area of second filter screen is less than first filter screen and relative both sides and all is equipped with spacing spring, the both sides that the second filter screen set up spacing spring all are equipped with conical surface type locating part and the structural face of rose box and offset the setting, be equipped with the screw that passes the face setting and set up with the conical surface of one side conical surface type locating part inconsistent on the working face of rose box structure, be equipped with on the side of sewage pipe and be equipped with the check valve in the pressure.
As an improvement, the filter box structure is provided with an air blowing nozzle which penetrates through the upper plate surface of the filter box structure.
As the improvement, first filter screen and second filter screen are stainless steel material.
As an improvement, the top pressure of the one-way valve is smaller than the suction force of the sewage pipe.
The utility model has the advantages that:
the utility model discloses simple structure uses two filter screens, can adjust the position of coincidence through the twist of screw and the twist of screw with second filter screen and first filter screen, thereby can adjust the size of filter mesh hole, can block the rubbish of big granule and be inhaled, it is equipped with the check valve to set up pressure release pipe and pressure release pipe, after filter screen blocking, can admit air, unload the pressure of water absorption port department, rubbish will drop under the dead weight, if there is rubbish can not drop then can blow in high-pressure air through the blowing nozzle.
