Concrete rotary mixer for constructional engineering

Abstract

The invention discloses a concrete rotary mixer for constructional engineering. The concrete rotary mixer for constructional engineering comprises a fixed base, two symmetrical supporting columns arefixedly connected to the upper surface of the fixed base, a driven rod is arranged between the two supporting columns, and a stirring barrel is arranged on the outer surface of the driven rod in a sleeving mode. A first bearing is arranged at the position, in contact with the stirring barrel, of the outer surface of the driven rod in a sleeving mode, an inner ring of the first bearing is fixedly connected to the outer surface of the driven rod, and the left and right ends of the driven rod both penetrate through the outer surfaces of the supporting columns and extend outside the supporting columns. A rack is arranged on the outer surface of the stirring barrel in a sleeving mode, the inner wall of the rack is fixedly connected with the outer surface of the stirring barrel, a driving motoris fixedly connected to the upper surface of the fixed base, a rotating rod is fixedly connected to the output end of the driving motor, and a gear is fixedly connected to one end, away from the driving motor, of the rotating rod. The concrete rotary mixer for constructional engineering has the advantages of simple structure, high work efficiency and long service life.

Description

technical field [0001] The invention relates to the technical field of heavy machinery, in particular to a concrete drum mixer for construction engineering. Background technique [0002] Heavy machinery generally refers to construction machinery, tower cranes, static pile drivers, construction elevators, submersible drilling machines, concrete mixing stations, crawler excavators, crawler bulldozers, crawler cranes, diesel pile drivers, road rollers, rotary drills Hole machine, high-speed winch, vibrating pile sinker, high-pressure rotary pile sprayer and concrete mixer. [0003] Concrete mixer is a machine that mixes cement, sand and gravel aggregate and water and mixes it into concrete mixture. It is mainly composed of mixing drum, feeding and unloading mechanism, water supply system, prime mover, transmission mechanism, frame and supporting device According to the structure of the mixing drum, it can be divided into pear type, drum type, double cone type, disc vertical sh...
