The utility model discloses a dust collection mechanism of a material
grinding machine, relates to the technical field of material
grinding machines, and solves the problems that when a
dust collector sucks a large amount of dust, a filter screen is extremely easy to block by the dust, the
suction force of the
dust collector is reduced, a motor is easy to load, and the motor is easy to
scrap. The
dust collector further comprises a V-shaped
pipe fixedly installed on the outer side of the dust collector body, a
threaded pipe communicated with the V-shaped
pipe is fixedly embedded in the lower end of the V-shaped
pipe, and the outer side of the
threaded pipe is sleeved with a dust receiving
barrel in a threaded mode. The filtering
assembly is used for pre-filtering air entering the dust collector main body; by installing the V-shaped pipe, the dust receiving
barrel and the filtering
assembly, the content of dust entering gas of the dust collector can be reduced, normal operation of the dust collector is facilitated, and by arranging the driving structure and the groove, the fixing frame and the filtering cloth can be driven to vibrate, so that the dust collecting effect is improved. Therefore, reduction of gas flow entering the dust collector due to accumulation of dust on the outer side of the filter cloth is avoided.
