Abstract

The invention discloses a shaft sealing mechanism for a motor mixer. A covering barrel is further fixed on a shaft lever located in a stirring barrel, one end of the covering barrel adopts a sealed structure, an opening is formed in the other end of the covering barrel, and the shaft lever penetrates through the covering barrel in the axial direction of the covering barrel; the opening end of the covering barrel is close to a shaft sleeve, an annular groove is formed in one surface, close to the covering barrel, inside the shaft sleeve, and the edge of the opening end of the covering barrel is rotationally clamped in the annular groove; the shaft sleeve in the stirring barrel and the inner wall of the covering barrel define a closed space, raw materials such as aggregate and the like in the stirring barrel can be effectively transferred to the inside of the shaft sleeve, shaft driving is effectively guaranteed, and leakage of raw materials such as aggregate and the like is also prevented.

Description

technical field [0001] The present invention relates to mortar mixer mechanisms and, in particular, to shaft sealing mechanisms for mortar mixers. Background technique [0002] Mortar mixer is a machine that mixes cement, sand and gravel aggregates and water and mixes them into mortar mixture. It is mainly composed of a mixing tank, a feeding and unloading mechanism, a water supply system, a prime mover, a transmission shaft, a frame and a supporting device, etc. Among them, the transmission shaft runs through the inside and outside of the mixing tank, and there will be a circumferential gap between the shaft and the mixing tank, through which the medium in the equipment will leak out, and raw materials such as sand, gravel, and cement will also enter the gap, affecting the shaft transmission. . Contents of the invention [0003] The purpose of the present invention is to provide a shaft sealing mechanism for a mortar mixer, which solves the problem that the sand and gra...
