Construction concrete mixing tank with double stirring apparatuses

Abstract

The invention provides a construction concrete mixing tank with double stirring apparatuses. The construction concrete mixing tank comprises a tank body; a stirring cavity is formed inside the tank body, an upper cover is arranged at the position of an opening in the top; a feeding pipe and a water adding and driving device are arranged on the upper cover; the water adding and driving device is composed of a transmission box, a first motor, a water feeding pipe and a rotary spraying disc; a spiral stirring device and a reverse stirring device are arranged in the stirring cavity; the spiral stirring device is composed of a first stirring shaft, a spiral stirring blade and a material scraping plate; the reverse stirring device is composed of a second motor, a second stirring shaft and stirring blades; and a discharging pipe is arranged on the side wall of the bottom of the tank body. According to the construction concrete mixing tank, the water adding and driving device is arranged, so that the spraying area and the spraying dynamics of clean water are conveniently expanded, and sufficient contact with concrete raw materials is conveniently achieved; and the reverse stirring device is arranged, the stirring direction of the reverse stirring device is opposite to that of the spiral stirring device, the mixing degree of the concrete raw materials is better improved, and the concrete quality is improved.

Description

technical field [0001] The invention relates to a concrete mixing machine, in particular to a construction concrete mixing tank with double mixing devices. Background technique [0002] With the further increase of urban development, there are more and more road constructions, so the demand for concrete is also increasing. Concrete is a very common building material, widely used in building construction and road construction. Concrete is a building material widely used in civil engineering. Cement is used as cementitious material, sand and stone are used as aggregate, mixed with water in a certain proportion, and obtained by mixing and molding. The mixing of concrete is very important, if the mixing is uneven, it will directly affect its performance. [0003] Patent No. CN 205521936 U discloses a concrete mixing device for road construction, comprising a mixing bucket, the underside of the mixing bucket is provided with a gear box, the center of the gear box is provided wi...

Problems solved by technology

[0004] In this patent, the concrete is mixed by the helical blade and the mixing plate, but the mixing area of ​​the helical blade and the mixing plate is limited, and the positions of the driven shaft and the driving shaft are fixed, there is a dead angle in the mixing tank, and the concrete is easy to adhere to the inner wall of the mixing tank In this patent, there is no treatment, resulting in insufficient concrete mixing, and it is easy to remain in the mixing tank when discharging, reducing the utilization rate of concrete
