Abstract

The invention discloses a double-horizontal-spindle concrete mixing and conveying apparatus, and comprises a bottom frame, and a material stirring tank which is upwardly arranged and is characterized in that the rear part is forwardly leaned is provided on the bottom frame, a discharging bucket is provided at the bottom of the front part of the material stirring tank, a sandstone feed inlet and a cement feed inlet are provided on the top face of the rear part of the material stirring tank, two mixer shafts which are longitudinally parallel are connected to the material stirring tank in a rotary mode, the two mixer shaft are driven by a power device and can rotate in a synchronous, same-rotating speed and opposite-rotating direction manner, charging spiral blades are equipped at the rear part of two mixer shafts, and the stirring spiral blades are respectively equipped at the central part and the front part of two mixer shafts, the stirring spiral blades on two mixer shafts are arranged in a corresponding mode, the inner bottom of the material stirring tank adapts to a contour line formed by the charging spiral blades and the stirring spiral blades while rotating, a spray pipe is provided on the central part of the inner chamber of the material stirring tank, and a plurality of blowholes which are transversally arranged are arranged on the spray pipe. The double-horizontal-spindle concrete mixing and conveying apparatus has the advantage of good stirring effect, and is capable of reducing the labor intensity of the workers and conveniently moving in a tunnel.

Description

technical field [0001] The invention relates to a twin-shaft concrete mixing and conveying device. Background technique [0002] The existing wet concrete spraying unit consists of three major parts: spraying mechanism, mixing mechanism and feeding mechanism. The main function of the mixing mechanism is to mix cement, sand, stones and water in a certain proportion, and pour them into the mixing bucket through the lifting hopper. Stir evenly, pour into the S-tube mixing barrel, send the slurry to the injection mechanism through the feeding structure, and finally send it to the construction site by the concrete delivery pipe of the injection mechanism, and the reciprocating cycle operation completes the roadway spraying work. The existing mixing mechanism only has a stirring function, but no feeding function, and the mixing effect is not ideal, and the phenomenon of uneven dryness and wetness of the concrete is serious. Above-mentioned multiple equipments are used simultaneou...
