Concrete mixer for construction site

Abstract

The invention relates to a concrete mixer for a construction site. The concrete mixer comprises a feed inlet, an outer mixing box, a mixing chamber, a plurality of first mixing sticks, a first mixingrod, a water injection pipe, a first motor and a water level inductor. The feed inlet is formed in the upper left part of the outer mixing box, the first motor is mounted on the left side of the outermixing box, the first motor is in transmission connection to the first mixing rod through an output shaft, the first mixing sticks are uniformly mounted on the first stirring rod, a weight inductionplate is mounted on the lower side of the outer mixing box, an induction control screen is mounted on the lower part of the weight induction plate, a water pump is arranged right above the weight induction plate, a water pumping pipe is mounted below the water pump, and a second motor is mounted on the lower part of the weight inductor. Concrete enters the mixing box from the feed inlet, after theweight induction plate weighs raw materials, enough water is added, and the first mixing sticks can mix the raw materials fully, so that concrete is free of bulk objects, and therefore, the quality of concrete is improved.

Description

technical field [0001] The invention relates to the technical field of industrial raw material mixing, in particular to a concrete mixer for a construction site. Background technique [0002] Concrete is an indispensable building raw material in human production and life. Concrete is made of cement, sand, stone, water and other materials. There are also strict requirements on the mixing ratio of various materials. There is strict quality assurance. [0003] At present, existing concrete mixers still have the problems of uneven mixing and difficult control of the volume of water added. First, the concrete mixer will produce blocky solids, which will affect the use of construction. 2. It is not easy to control the amount of water in the concrete production process. It is easy to add too much water or not enough water, resulting in the mixed concrete being too thin or too viscous. Contents of the invention [0004] The purpose of the present invention is to address the defi...
