Problems solved by technology

In the actual application process, due to the need to often put in raw materials from the feed port of the pulverizer, and the general raw materials are objects with many edges and corners such as stone, it is easy to wear and scratch the feed port of the pulverizer, thus making the crushing process difficult. Reduced machine usage time
Especially for the shaft in the pulverizer, it is often worn by raw materials, and it is easy to have problems and cause losses

Abstract

The invention belongs to the technical field of pulverizer tools and particularly relates to a shaft protective sleeve of a vertical-shaft pulverizer. The shaft protective sleeve comprises an upper sleeve and a lower sleeve, wherein an arc-shaped sleeve is arranged between the upper sleeve and the lower sleeve and bulges outwards, a pull ring is arranged at the top of the upper sleeve, a through hole is formed in the arc-shaped sleeve and penetrates through the arc-shaped sleeve, the lower sleeve is a cylinder, a shaft hole is formed in the lower shaft, and a protective cover is arranged at the lower end of the shaft hole. The shaft protective sleeve is reasonable in structure, a shaft is well protected, the protective sleeve can also be well protected, and the service life of the protective sleeve can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of pulverizers, in particular to a shaft protection sleeve for a vertical shaft pulverizer. Background technique [0002] A pulverizer is a machine that crushes large-sized solid raw materials into required sizes. The pulverizer is composed of coarse crushing, fine crushing, wind conveying and other devices, and achieves the purpose of pulverizing in the form of high-speed impact. It is mainly used in mining, building materials and other industries. In the actual application process, due to the need to often put in raw materials from the feed port of the pulverizer, and the general raw materials are objects with many edges and corners such as stone, it is easy to wear and scratch the feed port of the pulverizer, thus making the crushing process difficult. The operating time of the machine is shortened. Especially for the shaft in the pulverizer, it is often worn by raw materials, and it is easy to have pr...
