Trailer-mounted building material coating machine - with trough-shaped supply tank forming centre chassis longitudinal girder

摘要

The plastering or finishing machine incorporates a trough-shaped supply tank, open at the top, on a trailer chassis with a centre-pole, with an agitator-paddle shaft above the botom and connection to an eccentric rotary pump with tube attachment, on the pole side, and drive motor on the opposite side with continuously regulated agitator shaft drive, and there are a mixer and an air-compressor on top. Stability and adaptability to various types of building material are enhanced by designing the V-sectioned trough container to serve as longitudinal girder for the chassis. There may be end pairs of spreader legs, the rear one carrying the wheel axle and the front one accommodating extensible support legs, and with extensions on both to suppor the mixer at the top.
