Cement mixer

Abstract

The invention provides a cement mixer which comprises a base, a mixing drum, a motor, a rotation shaft, upper mixing blades and lower mixing blades. A feeding port and a feeding hopper are formed in the top of the mixing drum, and a discharging port and a sealing door are arranged at the root of the side wall of the mixing drum. A plurality of shock absorbers are connected between the bottom of the mixing drum and the base, and the two ends of each shock absorber are connected with the mixing drum and the base through spherical pairs. A plurality of stand columns are uniformly arranged on thebase along the circumferential direction of the mixing drum, a shock absorber is connected between each stand column and the side wall of the mixing drum, and the two ends of the shock absorber is connected with the mixing drum and the stand column through the spherical pairs. Two lower mixing blades are arranged, and the lower mixing blades are fixed to the lower part of the rotation shaft. The lower side of one lower mixing blade is connected with a lower scraper, and a vertical scraper is arranged at the end part of the other lower mixing blade. Two upper mixing blades are arranged, the upper mixing blades can move up and down along the rotation shaft, and a vertical scraper is arranged at the end part of one upper mixing blade. The cement mixer can prevent materials from remaining on the inner wall of the stirring drum, has a good shock absorption effect, and cannot generate the phenomenon that the mixing blades are idle.

Description

technical field [0001] The invention relates to a construction mechanical equipment, in particular to a cement mixer. Background technique [0002] Cement mixers are usually used on construction sites to mix concrete. After the existing cement mixers are finished mixing, there will be a lot of materials remaining on the inner wall of the mixing drum, which not only wastes materials, but also will affect the subsequent mixing effect if they accumulate too much. In addition, Ordinary cement mixers only have shock absorbers at the bottom of the mixing drum. These shock absorbers can only reduce the vibration in the up and down direction, but cannot reduce the horizontal vibration. The shock absorption effect is poor and the noise is large; in addition, the height of the mixing blade is usually fixed. , when there is less material, there will be a phenomenon that the stirring blades are idle. [0003] It can be seen that the prior art needs to be improved and enhanced. Conten...
