Intelligent agricultural straw dust-free crushing equipment

The invention discloses intelligent agricultural straw dust-free crushing equipment, which belongs to the technical field of agricultural instruments and comprises a barrel, a top cover, a feed hopper, a positioning plate, a storage cavity, a crushing mechanism, a dust collection mechanism, a motor, a screen, a sealing plug and a discharge port. The rotation directions of the two driving shafts are opposite, when the driving shafts rotate, driving wheels are driven to rotate, when the driving wheels rotate, crushing teeth at the outer ends of the driving wheels are driven to rotate, and therefore straw fed through a feeding hopper can be crushed; the dust outlet pipe is externally connected with a dust suction machine, and after the dust outlet pipe is communicated with the dust suction machine, dust generated during crushing in the barrel can be sucked into the dust suction nozzle, then enters the connecting pipe through the dust suction pipe and is introduced into the dust outlet pipe through the connecting
