Embodiment Construction

[0014] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.

[0015] Such as figure 1 with figure 2 Shown: The present invention provides a shaft sealing mechanism for a mortar mixer, characterized in that the shaft sealing mechanism includes a shaft sleeve 2 installed on the mixing barrel 1, and the two ends of the shaft 3 are the first ends. And the second end, the first end of the shaft 3 is located outside the mixing barrel 1, and the second end of the shaft 3 penetrates the shaft sleeve 2 and extends to the inside of the mixing barrel 1. A bearing 4, a first sealing ring 5 and a second sealing ring 6 are respectively sleeved from one end to the second end. The bearing 4, the first sealing ring 5 and the second sealing ring 6 ar...

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 invention relates to a mortar mixer mechanism, in particular to a shaft sealing mechanism for a mortar mixer. Background technique [0002] The mortar mixer is a machine that mixes cement, sand and gravel aggregates and water and mixes them into a mortar mixture. It is mainly composed of mixing barrel, feeding and unloading mechanism, water supply system, prime mover, transmission shaft, frame and supporting device. Among them, the transmission shaft runs through the inside and outside of the mixing barrel, and there will be a circumferential gap between the shaft and the mixing barrel. The medium in the equipment will leak out through the gap, and raw materials such as sand and cement will also enter the gap, affecting the shaft transmission. . Summary 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 raw materials such as sand and gravel in the mixi...
