Pulverizing device for fan and fan comprising pulverizing device

Abstract

The invention relates to a pulverizing device for a fan and the fan comprising the pulverizing device, and solves problems that the conventional fan is incomplete in function, complicated in equipment, easy to block a volute casing, and easy to damage. The pulverizing device comprises rotating disks, connecting shafts, spacer bushes and pulverizing blades, wherein the rotating disks are disk-like bodies having annular sleeves at centers; the rotating disks are arranged in pairs by using one end surface of the sleeve as a symmetrical plane; a plurality of connecting shafts are arranged between opposite sides of the rotating risks; the connecting shafts are fixed on the two rotating disks; a plurality of pulverizing blades sleeve the connecting shafts; the spacer bushes are arranged between each pulverizing blade and each rotating disk and between the pulverizing blades; the spacer bushes are fixedly connected with the connecting shafts. The pulverizing device has advantages of simple structure, assembly / disassembly and maintenance convenience, is used in coordination with the fan, can pulverize while suction so as to avoid fan blocking phenomenon and influence on suction wind, has good pulverization and suction effects and high efficiency, is not easy to damage, and has long duration of work and small interference.

Description

Technical field [0001] The invention relates to a crushing device, in particular to a crushing device for a fan. Background technique [0002] As a typical model and key application tool of urban sanitation vehicles, road sweepers have been well developed, and various technologies have become mature. The fan is a key component of the road sweeper. [0003] The current sweeper fans on the market only have a suction function, but do not have a crushing function. When sucking large materials such as fallen leaves, it is easy to cause the volute blockage and affect the suction power of the fan. [0004] Even if the fan has a crushing function, most fans and crushing devices are separated from each other, or exist on different equipment or have different structures independently set up on the same equipment. When these two functions are required at the same time, it is inevitable that there will be many equipment and equipment. The complex structure and the need to complete the operatio...

AI Technical Summary

Problems solved by technology

[0003] At present, the road sweeper fans on the market only have the suction function and do not have the crushing function. When sucking large materials such as fallen leaves, it is easy to cause the clogging of the volute, which affects the suction force of the fan.

[0004] Even if the fan has the function of crushing, most of the fans and crushing devices are separated from each other, or exist on different devices or are different structures independently installed on the same device. The structure is complicated and needs to be completed in two operations, which leads to many inconveniences such as large equipment investment, troublesome configuration and installation, and many production processes.
