Intelligent efficient dust-free straw crushing equipment

The intelligent efficient dust-free straw smashing equipment structurally comprises a smashing bin, a driver, a discharging pipe, a base and a feeding hopper, the smashing bin is fixed to the upper end of the base, the driver is connected with the right side of the smashing bin, the discharging pipe is fixed to the position, close to the lower portion, of the right side of the smashing bin, and the feeding hopper is welded to the upper end of the smashing bin; through cooperation of the outer contact surface on a powder stopping block at the bottom of a baffle and an outer protruding point block, powder generated by straw smashing and floating upwards in the smashing bin can be intercepted, the powder is attached to holes in the surface of polyester sponge, an intercepting piece can be bent to a small extent under stress and then reset, and therefore straw fragments can be rebounded into the smashing bin, and the straw smashing efficiency is improved. And the overall weight of the rotating roller can be incre
