On described screw pump, be provided with reducing pressure gauge base, on described reducing pressure gauge base, detachable pressure meter be installed.Can detect the operating pressure of screw pump, prevent from stopping up the rear screw pump pressure damage equipment that sharply rises.
Described hopper longitudinal section is " V " font, and described spiral shaft is positioned at the bottom of " V " font; The bottom of described hopper is also provided with washing outlet to be opened/closed.Hopper longitudinal section is " V " font can farthest make the utilization rate of slurry improve, and reduces loss; Washing outlet can conveniently be discharged the waste material waste water producing in cleaning process, and plant maintenance is simple and easy.
Described drive unit is variable-frequency motor, and the power output shaft of described variable-frequency motor is connected with described spiral shaft through a seal lubrication chamber; On described seal lubrication chamber, have lubrication oil and add entrance.Lubrication oil adds entrance and is connected with an oil pump being arranged in frame, can conveniently add the needed lubrication oil of running.
Described feeder comprises startup control module and air compressor.Described pneumatic control module comprises the pressure switch of adjustable upper downforce threshold and safety valve, one way valve.
Described electrical control gear comprises electric operation case and frequency-variable controller.
Described vehicle frame comprises frame, is arranged on universal wheel and road wheel under described frame, and described frame is also provided with handgrip.Facilitate the carrying of equipment to move.
The electrical control gear that adopts the technical solution of the utility model to be provided with is provided with frequency-variable controller.The feeding speed that can control feeding device by variable frequency control drive unit, to adapt to different slurries, carries out spraying operation smoothly.Break through the shortcoming of Mortar spraying machine material bad adaptability in the past.Feeder is integrated on vehicle frame, overcomes and think the dumb shortcoming of equipment independent gas supply.When slurry filters and enters after hopper through screen filtration device, stir and prevent slurry segregation through the blade rotation of spiral shaft, slurry is pushed toward screw pump intake simultaneously, the hopper of " V " character form structure can be sucked the slurry in hopper substantially more thoroughly by screw pump, reduce remaining surplus material.Be delivered to spray gun by feed pipe for mortar, being sprayed in the scope of operation at a high speed after the high-pressure air pipe winding-up atomization of spray gun front end from screw rod pump housing slurry continuous high speed out.The utility model is also provided with dust cover, and dust cover has reduced the pollution electrical control gear of slurry in charging process, and screen filtration device can prevent that bulk impurity from falling into hopper so that stuck or damage screw pump.State universal wheel and road wheel under frame, described frame is also provided with handgrip.Facilitate the carrying of equipment to move.The utility model equipment is to slurry strong adaptability, simple to operate, is easy to safeguard, convenient transfer carried.
