A drum concrete mixer

Abstract

The invention discloses a drum-type concrete mixer, which relates to the technical field of construction machinery. The rack roller is movably matched with the drum, and a universal shaft is installed on one side of the drum. The beneficial effects of the present invention are: the present invention is set by the combination of the movable ring and the stirring assembly, and the rack ring in the movable ring is rotated to make the rack move in a circle. Drive the gear to rotate, so that the longer side of the mixing blade is turned inward, so that the entire mixing assembly can be pulled out, and the groove disc pushes the concrete remaining on the cylinder wall to the material port from the inside, preventing the remaining concrete from hardening on the cylinder wall. After the mixing assembly is pulled out, the entire mixing assembly can be washed to prevent the hardening of the concrete from affecting the rotation of the movable ring and preventing the concrete from blocking the through holes on the mixing blade to affect the mixing effect.

Description

technical field [0001] The invention relates to the field of construction machinery, more specifically, to a drum type concrete mixer. Background technique [0002] Concrete is needed in the construction industry, and the concrete mixer is a machine that mixes cement, water and stone and mixes it into a concrete mixture. Concrete mixers can be seen in places as large as national projects and small in families where concrete is needed. Manual mixing is time-consuming and labor-intensive and uneven mixing results in poor concrete quality. [0003] The small drum concrete mixer mixes the internal mixture into concrete by rotating and rolling. When pouring out the concrete, the concrete is poured out by the pouring of the drum concrete mixer. Due to the viscosity of the concrete, it is impossible to pour the concrete. The concrete is completely poured out, and the concrete remaining on the cylinder wall will harden, and the hardened concrete will affect the next mixing of the c...

[0002] Concrete is needed in the construction industry, and a concrete mixer is a machine that mixes cement, water and stones and mixes them into concrete mixtures. Concrete mixers can be seen in places ranging from national projects to small households that need concrete. Manual mixing is time-consuming and labor-intensive and uneven mixing results in poor concrete quality

[0003] The small drum concrete mixer mixes the internal mixture into concrete by rotating and rolling. When the concrete is poured out, the concrete is poured out through the drum concrete mixer. Because the concrete is viscous, it cannot be poured. Pour out the concrete completely, and the concrete remaining on the wall of the cylinder will harden, and the hardened concrete will affect the mixing of the concrete next time. In addition, the mixing blades of the drum concrete mixer are generally provided with through holes, and the mixing blades are fixed. On the inner wall of the cylinder, the residual concrete will block the through hole, causing the mixing blades to fail to fully mix the concrete
