Problems solved by technology
However, at present, the stirring shaft used in the mixer adopts an integral square shaft or a round shaft, which has the following defects in structural design: on the one hand, the barrel of the mixer is long, and the integral stirring shaft has high requirements on the manufacturing process, the weight of the shaft is large, and the cost High, and the deflection in the middle of the shaft is large, it is prone to instability during work, which will cause great damage to the bearing and affect the service life of the mixer. On the other hand, the mixer uses an integral square or round shaft. Once the shaft end or shaft body is damaged, The entire shaft must be replaced, which is complex, long-term, and costly. Therefore, the current stirring shaft is poor in economy and interchangeability

The invention provides a stirring shaft, comprising: a connecting shaft, and a left drive shaft and a right shaft are respectively detachably fixed at both ends of the connecting shaft. The stirring shaft provided by the invention has the characteristics of safety, reliability, economy and practicability. The manufacturing process of the flange type stirring shaft is relatively simple, the equipment is easy to maintain, and has good popularization and practical value. Widely popularized and applied in full tailings paste filling mine system engineering, it will produce good economic and social benefits.
Description
technical field [0001] The invention relates to the mechanical field, in particular to a stirring shaft and a stirring machine containing the stirring shaft. Background technique [0002] The full tailings paste filling mixer is a new type of mixer developed with the full tailings paste filling process in recent years, including twin-shaft blade mixers and twin-shaft spiral mixers. The whole tailings paste mixer is developing toward automation and large-scale to meet engineering needs. However, at present, the stirring shaft used in the mixer adopts an integral square shaft or a round shaft, which has the following defects in structural design: on the one hand, the barrel of the mixer is long, and the integral stirring shaft has high requirements on the manufacturing process, the weight of the shaft is large, and the cost High, and the deflection in the middle of the shaft is large, it is prone to instability during work, which will cause great damage to the bearing and aff...
