Mixing shaft movable type concrete mixer

Abstract

The invention discloses a mixing shaft movable type concrete mixer which comprises supporting legs. The top ends of the supporting legs are fixedly connected with a mixing box. The upper surface of the mixing box is fixedly connected with a motor rack. The motor rack is fixedly connected with a servo motor. An output shaft of the servo motor penetrates the upper surface of the mixing box to be fixedly connected with a first gear. A circular ring is fixedly connected to the top of the inner wall of the mixing box. A gear rail is arranged on the inner wall of the circular ring. An annular through hole is formed in the upper surface of the mixing box, and a concave block is connected into the through hole in a clamped manner. The mixing shaft movable type concrete mixer is provided with the servo motor, the first gear, the gear rail, the concave block and a mixing shaft, when the servo motor operates, the first gear is linked with a second gear to enable the second gear to rotate around the first gear, the mixing shaft rotates around the first gear while rotating, and therefore mixing rods irregularly move in a mixing tank, materials attached to the tank wall of the mixing tank can be mixed, and material mixing is more sufficient.

Description

technical field [0001] The invention relates to the technical field of machinery industry, in particular to a concrete mixer with a stirring shaft movement. Background technique [0002] Concrete mixer is a machine that mixes cement, sand and gravel aggregate and water and mixes it into concrete mixture. It is mainly composed of mixing drum, feeding and unloading mechanism. The rod fully mixes cement, sand and gravel aggregates and water, so as to achieve the purpose of mixing and processing materials. The general mixers on the market fix the stirring shaft, and drive the stirring shaft to rotate through the motor, so that it is connected with the stirring shaft. The stirring rod of the mixing device moves axially to drive the mixing of the materials in the mixing tank. However, some materials in the mixing tank of this stirring device will stick to the inner wall of the mixing tank, so that the materials cannot be fully stirred.
