Stirring device for concrete processing

Abstract

The invention discloses a stirring device for concrete processing. The stirring device for concrete processing comprises a stirring cavity. The top of the stirring cavity is provided with a feed port.A first motor is arranged on one side of the feed port. The end of an output shaft of the first motor is connected with a first shaft lever. The first shaft lever is sleeved with a first gear. The first gear is in engaged connection with a second gear. The second gear is sleeved on a second shaft lever. Through the stirring device provided by the invention, a concrete raw material is fed into thefeed port of the stirring cavity, the output shaft of the first motor drives the first shaft lever to rotate, the first shaft lever drives the first gear to rotate, the first gear is engaged with thesecond gear to drive the second shaft lever to rotate, the first shaft lever and the second shaft lever drive two crushing rolls to rotate face to face, the two crushing rolls crush big-particle solid and impurities in the concrete raw material, and the crushed raw material is fed into a crushing cavity. Through the stirring device for concrete processing, the technical problem that the synthesiseffect of concrete is affected by the big-particle solid and the impurities in a raw material in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of concrete processing, in particular to a mixing device for concrete processing. Background technique [0002] Concrete refers to the general designation of engineering composite materials that use cementitious materials to cement aggregates into a whole. The term concrete usually refers to the use of cement. Concrete cannot be used directly. Before use, cementitious materials and granular aggregates need to be It can be used after mixing and stirring with water in a certain proportion. The concrete mixing device is a machine that mixes cement, sand aggregate and water and mixes it into concrete mixture. [0003] With the rapid development of the construction industry, concrete mixing devices are becoming more and more diverse. Usually, a stirring shaft is inserted into the container for mixing. Since the stirring shaft can only be stirred to the middle of the container, such a stirring device is likely to ...

Problems solved by technology

[0004] The purpose of the present invention is to provide a mixing device for concrete processing to solve the following technical problems: (1) by putting concrete raw materials into the feeding port of the mixing chamber, the first motor output shaft drives the first shaft to rotate, and the first The shaft drives the first gear to rotate, the first gear meshes with the second gear to drive the second shaft to rotate, the first shaft and the second shaft drive the two crushing rollers to rotate in opposite directions, and the two crushing rollers have a large impact on the concrete material The particles are fixed and the impurities are crushed, and the crushed raw materials enter the mixing chamber. Through this setting, the technical problem that there are large particles of solids and impurities in the raw materials that will affect the synthesis of concrete in the prior art is solved; (2) output through the second motor The shaft drives the first bevel gear to rotate, the first bevel gear meshes with the second bevel gear to drive the first rotating shaft to rotate, the first rotating shaft drives the paddle blade and the two rotating blades in the stirring chamber to rotate, the paddle blade drives the two vertical The vertical blades rotate, the paddle blades are inclined and arranged at the bottom of the stirring chamber, and the vertical blades are vertically arranged in the stirring chamber. Through this setting, the technical problems of uneven stirring and low stirring speed efficiency in the prior art are solved; (3 ) By opening the control valve on the first discharge port at the bottom of the mixing chamber, the concrete is delivered to the screening chamber, the output shaft of the third motor drives the crank to rotate, and the crank rotates to drive the round pin and the active tray to make a circular motion, thereby driving the groove wheel to rotate intermittently , the intermittent rotation of the grooved wheel drives the intermittent rotation of the arc-shaped rotating block. At this time, the concrete in the screening chamber is limited above the arc-shaped sieve plate, and the concrete is screened by the arc-shaped sieve plate and filtered out to the second outlet. Through the next rotation of the arc-shaped rotating block, the grooves on the arc-shaped rotating block scrape out the particles that cannot be filtered out on the arc-shaped sieve plate through the waste port. Through this setting, the impact of impurities in the concrete in the prior art is solved. quality technical issues
