The utility model has short material mixing time and high efficiency, and can improve the efficiency by 2-3 times; the mixing capacity is large, the charging coefficient is improved by 20-30% compared with that of a drum type, and no dead angle exists in the mixing of materials.

Description

Cement mixer

Technical Field

The utility model belongs to building field equipment for stirring cement mortar.

Background

The construction of the small amount of cement quantity inevitably appears in the building field, and it is with high costs to use the concrete tank car, adopts artifical compounding intensity of labour big and great to environment and workman's healthy adverse effect.

Disclosure of Invention

In order to alleviate intensity of labour, the utility model provides a cement mixer that work efficiency is high and environmental pollution is little.

The cement mixer comprises a large motor, a small motor and a hopper, wherein the hopper is conical, an upper cover covers the hopper, and is provided with a feed inlet, and the cement mixer is characterized in that at least two stirring screw rods are arranged in the hopper, one long screw rod and one short screw rod are arranged in the two stirring screw rods, an included angle between the long screw rod and the short screw rod is 25-50 degrees, and the long screw rod and the short screw rod are parallel to the hopper wall on the respective adjacent sides; the large motor is fixedly arranged on the upper cover, an output shaft of the large motor is connected with the speed reducer, and an output shaft of the speed reducer is connected with the rotating frame through the coupling; the swivel mount comprises well core rod, two rocking arms, and well core rod is connected as an organic wholely with two rocking arms, and every rocking arm all connects a small motor, and a small motor connects the reduction gear, and the reduction gear connection is long hob, and another small motor passes through the short hob of reduction gear connection, and the bleeder valve is installed to the discharge gate of hopper.

The bleeder valve comprises apron, mounting bracket, cylinder or pneumatic cylinder, and the mounting bracket welds around hopper discharge gate outer wall a week, and the articulated mounting bracket of apron, the articulated apron of cylinder or pneumatic cylinder, cylinder or pneumatic cylinder are installed on the mounting bracket.

The reducer adopts a shaped cycloid pinwheel reducer.

The rotation of the long screw rod and the short screw rod of the utility model lifts the material upwards, and the revolving frame revolves slowly; the materials outside the long screw rod and the short screw rod enter the stud in different degrees, so that the materials in the full circumference direction are continuously updated and diffused, the two materials at the upper part are merged to the axis to form a downward material flow, and the vacancy at the bottom is supplemented, so that convection circulation is formed; the conical hopper can meet the requirement that the materials have enough material alternate circulation under the spiral lifting action.

The utility model has short material mixing time and high efficiency, and can improve the efficiency by 2-3 times; mixing ability is big, and the coefficient of charging improves 20~30% than the drum-type, and the mixture of material does not have the dead angle, and theoretically, the hob is more, and the better is the mixing effect.
