Mixer for concrete and similar mixtures

Abstract

The invention relates to a stirrer for concrete and analogous mixtures, comprising a rectangular stirring cylinder which is provided with one or a plurality of stirring shafts inside, the rotation of each of which is driven by a corresponding engine located out of the stirring cylinder; the engine system is composed by connecting an electromotor, a gear electromotor with an intermediate gear connected to the top of the corresponding stirring shaft via necessary connection components; the invention has the characteristic that the electromotors and the corresponding gear electromotor of each engine system are all fixed on the same support framework, the framework is hung at the side of the stirring cylinder via one or a plurality of hinges; the stirrer for concrete and analogous mixtures has the characteristics of simple and fast maintenance and repairing.

Description

technical field [0001] The invention relates to a mixer for concrete and similar mixtures, characterized by simple and fast maintenance, for mixing concrete, powder, dry and semi-dry granules. Background technique [0002] As we all know, the traditional mixer used in different industries, especially the construction industry, is composed of a large rectangular mixing tank, the inner wall is cylindrical or omega-shaped, and there are one or several stirring shafts in the tank to stir and put them into the tank in a horizontal direction. aggregate. [0003] The above-mentioned stirring shaft is equipped with a specially designed radioactive stirring knife to improve the efficiency of stirring the aggregate. [0004] The lateral sides of the mixer bowl are fitted with shaft end fittings for insertion of the mixer shaft, containing appropriate gears and seals. [0005] The motor system for rotating each agitator shaft is mounted externally on one or both lateral sides of the ...

AI Technical Summary

Problems solved by technology

[0013] This operation is complicated and difficult, because it is necessary to remove the belt connecting the gear motor and the motor first, then remove the device that fixes the gear motor bell to the load-bearing side of the cylinder, and finally the gear motor needs to be hung on a lifting device to remove it from the agitator cylinder

[0014] The operation using lifting equipment is also quite difficult, because the location of the concrete mixer is usually at a certain height from the ground due to the support of appropriate brackets, or in a closed environment (such as a mixing tower)

[0015] Moreover, the operation of lifting heavy objects will seriously endanger the safety of operators
