The invention relates to
straw crushing equipment with an
air purification function. The
straw crushing equipment comprises a main body, a first motor, a rotating shaft, a
sieve plate, two oscillators, two support legs and a plurality of crushing cutters, and further comprises an auxiliary mechanism and two
air purification mechanisms, wherein the auxiliary mechanism comprises a
shunting block, a connecting block, two connecting rods, two pressure sensors and two adjusting assemblies, and each
air purification mechanism comprises a fixed box, a water box, a connecting box, an air extracting
assembly, a circulating
assembly, a filter screen and a moving
assembly. The
straw crushing equipment with the air purification function can block a feeding
pipe to stop discharging through the auxiliary mechanism when excessive scraps are accumulated on the
sieve plate, meanwhile, the
sieve plate can be driven to move upwards, the crushing cutters can conveniently crush scraps which do not conform to specifications, so that the phenomenon that the discharging speed is influenced due to the fact that the sieve plate is blocked by straw is avoided, the crushing efficiency and quality of the equipment are improved, the purpose of air purification is achieved through the air purification mechanisms, and the situation that the surrounding air quality is affected due to overflowing of dust is prevented.
