Mixer with intermittent discharging function for concrete production

Abstract

The invention relates to a mixer with the intermittent discharging function for concrete production. The mixer comprises a mixing box, a transmission shaft, a driving motor, stirring shafts, bottom damping sheets, spring dampers, a material blocking plate, a connecting rod, a mounting part, a gear, a motor, an intermittent gear, a rotating shaft and a high-elasticity torsional spring, wherein thetransmission shaft is fixedly connected to the output end of the driving motor, the stirring shafts are arranged on the transmission shaft, the spring dampers arranged at the lower end surface of themixing box, the bottom damping sheets are tightly connected to the spring dampers, the gear is arranged on the rotating shaft, the intermittent gear is arranged at the output end of the motor, the mounting part is fixed to the right end of the connecting rod and is fixed to the rotating shaft, and the high-elasticity torsional spring is fixedly arranged at the front end surface of the mixing box and sleeves the outer side of the rotating shaft. The mixer has the advantages that the material blocking plate is additionally arranged, so that a feed port can be intermittently closed, and thereforethe purpose of intermittent discharging can be achieved, the stirring effect can be improved, the instantaneous load of equipment can be reduced, and the service life of the equipment can be prolonged.

Description

technical field [0001] The invention relates to the field of concrete production equipment, in particular to a concrete production mixer capable of intermittent feeding. Background technique [0002] Concrete: refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. Concrete can be divided into heavy concrete, ordinary concrete and lightweight concrete according to the apparent density. The difference between these three types of concrete is the difference in aggregate. Heavy concrete is made of particularly dense and heavy aggregates with an apparent density greater than 2500 kg / m3. Such as b...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a concrete production mixer capable of intermittent feeding, so as to solve the problem that all raw materials of the traditional mixing equipment proposed in the above-mentioned background technology are put into the feeding port together, and the amount is all manually controlled. On the one hand, the amount is large. The load on the equipment is heavy, the service life of the equipment is shortened, on the other hand, the raw materials are put into the mixing box together, and the mixing effect is poor.
