[0053] Working principle: When it is necessary to crush the building materials, the workers put the building materials into the inside of the protective shell 14, and place the lower pressing plate 222 in the inside of the protective shell 14 under the action of gravity, so that the bottom of the lower pressing plate 222 is in contact with the building materials in the inside of the protective shell 14. Then, the electric motor one 11 and the electric motor two 332 are started, the electric motor one 11 drives the crushing roller 15 to rotate, and the building materials in the inside of the protective shell 14 are crushed. With the crushing of the building materials, the crushed building materials fall from the discharge port 12 and are uniformly collected by the cart. With the reduction of the building materials in the inside of the protective shell 14, the lower pressing plate 222 gradually descends along the chute 21 under the action of gravity, so that the building waste is better in contact with the crushing roller 15, different shapes of building materials can be extruded, the continuous rolling of the building waste is avoided, the crushing efficiency is higher, the use time of the electric motor is reduced, the electric energy is saved. At the same time, the dust after crushing enters the inside of the chamber two 30 from the air inlet hole 31, and then enters the inside of the sleeve 351 from the chamber two 30, the air outlet 32 and the air outlet hole 352. The electric motor two 332 drives the gear one 333 to rotate, the gear one 333 drives the gear two 334 to rotate, the gear two 334 drives the threaded pipe 354 to rotate, the threaded pipe 354 drives the spiral blade 355 to rotate, so that the gas in the inside of the sleeve 351 is discharged from the exhaust pipe 356. The rapid discharge of the dust reduces the influence of the dust on the workers, saves the time of the workers waiting for the dust to disperse, the workers can add building materials faster, the building materials can be added earlier, the crushing can be carried out earlier, the working time of the electric motor is reduced, and the electric energy is saved.

[0054] The lower pressing plate 222 is pressed down along the slide rod 221 under gravity, and the insertion rod 233 is locked to prevent rebounding after falling by a distance of one triangular groove 20. The dust removal system is started synchronously, and dust enters the chamber two 30 through the air inlet hole 31 and is sucked to the exhaust pipe 356 by the spiral blade 355.
