Concrete stirrer with high stirring efficiency

Abstract

The invention relates to a concrete stirrer with high stirring efficiency. The concrete stirrer comprises a base, a first supporting plate, a second supporting plate, a main body, a control room, a discharge box, a control mechanism, a discharge mechanism and a turnover mechanism, wherein the control mechanism comprises a lifting air cylinder, a fixed plate, a first bearing, a first rotary shaft, a first bevel gear, a sleeve, a second bearing, a second bevel gear, a telescopic air cylinder, a drive motor, a third bevel gear and a third bearing; the discharge mechanism comprises a rotary motor and a screw; and the turnover mechanism comprises a turnover motor, a speed reducer, a first belt wheel, a second belt wheel and a transmission belt. The concrete stirrer adopts dual stirring modes which are simultaneous and reverse, and discharge adopts a screw squeezing type discharge method, so that discharge stability is improved; and moreover, during discharge, concrete is stirred again through a screw in a reversible mode, and the concrete stirrer further can regulate the position of a discharge hole; and the base of the concrete stirrer is equipped with universal wheels, so that travelling is convenient.

Description

technical field [0001] The invention relates to a concrete mixer with high mixing efficiency. Background technique [0002] Concrete mixer is a machine that mixes cement, gravel aggregate and water and mixes it into concrete mixture. It mainly consists of mixing drum, feeding and unloading mechanism, water supply system, driving mechanism, transmission mechanism, frame and supporting device, etc. composition. [0003] Most of the existing concrete mixers have the following problems: 1. The mixing is not uniform. Since the existing technology uses a rotating shaft to drive the mixing blades for one-way mixing, the efficiency of this mixing method is not high; 2. The discharge method is mostly used in the Free fall under the action of gravity, this mode is likely to cause incomplete discharge, and the concrete is easy to stick to the discharge plate; 3. The body is bulky and difficult to carry; 4. It is impossible to see the situation in the mixing chamber, which is not good ...
