[0062] It should be noted that the adjectives "one", "multiple" mentioned in the present disclosure are illustrative and not limiting, and those skilled in the art should understand that unless the context clearly indicates otherwise, it should be understood as "one or more".

[0063] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0064] Referring to Figures 1-7 , the building construction material crusher comprises a support 101, a crushing box 102, a main shaft 103, a crushing roller 104, a driving member 105, a screen 106, a pushing device 107, and a reset group 108. The crushing box 102 is fixed on the support 101 and has a first outlet 102a and a second outlet 102b. The first outlet 102a is located on one side of the crushing box 102, and the second outlet 102b is located below the crushing box 102. The main shaft 103 is fixed on the support 101 and located in the crushing box 102. The crushing roller 104 is fixed on the main shaft 103. The driving member 105 is a DC motor and is arranged on the support 101 and connected with the main shaft 103 through a belt wheel transmission. The screen 106 is movably arranged at the second outlet 102b. The pushing device 107 is arranged on the main shaft 103 and abuts against the side wall of the screen 106, and is used for pushing the screen 106 to move horizontally. The reset group 108 is arranged on the crushing box 102 and is used for pushing the screen 106 to move reversely horizontally.

[0065] The starting driving member 105 drives the main shaft 103 and the crushing roller 104 to rotate. The construction material is poured into the crushing box 102. After being crushed by the crushing roller 104, the construction material is crushed into large particles and small particles. The small particles are filtered by the screen 106 and discharged from the second outlet 102b. The large particles are discharged from the first outlet 102a. In this way, the crushed material after crushing the construction material can be divided into two piles with different sizes of large particles. In this embodiment, the crushing box 102 can be arranged from high to low in the direction from the second outlet 102b to the first outlet 102a. Therefore, when the construction material enters, the large particles move out of the material in the direction of the first outlet 102a by the rotation of the crushing roller 104 in the inclined crushing box 102.

[0066] When the main shaft 103 rotates, the pushing device 107 rotates, the screen 106 slides horizontally, the reset device resets the screen 106, the reciprocating sliding of the screen 106 is realized, the crushed material blocked at the screen 106 is shaken out, and the screen 106 is prevented from being blocked.

[0067] The reset group 108 includes a first abutting piece 108a, a second abutting piece 108b, a through rod 108c, and a second spring 108d. The first abutting piece 108a is fixed on the crushing box 102, and the first abutting piece 108a has an opening 108e. The second abutting piece 108b is fixed on the screen 106. The through rod 108c penetrates the opening 108e and is fixed on the second abutting piece 108b. The second spring 108d is sleeved on the through rod 108c, and the second spring 108d is located between the first abutting piece 108a and the second abutting piece 108b. The two ends of the second spring 108d are fixed on the first abutting piece 108a and the second abutting piece 108b, respectively.

[0068] The pushing device 107 includes a connecting ring 107a and a protrusion 107b. The connecting ring 107a is fixed on the main shaft 103 and rotates synchronously with the main shaft 103. The protrusion 107b is slidably arranged on the connecting ring 107a and located on one side of the connecting ring 107a close to the screen 106. The protrusion 107b abuts against the screen 106. The two sides of the protrusion 107b are inclined surfaces, which can quickly insert between the screen 106 and the connecting ring 107a and push the screen 106.

[0069] The main shaft 103 rotates to drive the connecting ring 107a to rotate, and then drive the protrusion 107b to rotate. The protrusion 107b pushes the screen 106 to slide. At the other end of the screen 106, the second abutting piece 108b moves synchronously with the screen 106. When the screen 106 moves towards the first abutting piece 108a, the second spring 108d is compressed. When the protrusion 107b is separated from the screen 106, the elastic force of the spring is released, pushing the second abutting piece 108b to move away from the first abutting piece 108a, driving the screen 106 to reset. The next time the protrusion 107b abuts against the screen 106, the screen 106 is pushed to move, forming a cycle, so that the screen 106 is shaken.

[0070] The connecting ring 107a comprises a connecting part 107c and a circular ring part 107d. The connecting part 107c is fixed on the main shaft 103. The circular ring part 107d is circular and fixed on the connecting part 107c. A through hole 107e is formed on the circular ring part 107d and extends along the circumference of the circular ring part 107d in an arc shape. A connecting rod 107f is fixed on the protrusion 107b and slides along the circumference of the circular ring part 107d in the through hole 107e. First springs 107g are fixed on both sides of the connecting rod 107f, and the two ends of the first springs 107g are fixed on the connecting rod 107f and the inner wall of the through hole 107e, respectively.

[0071] A guide rod 109 is fixed on the end of the connecting rod 107f away from the protrusion 107b. The guide rod 109 is rotatably arranged on the circular ring part 107d. A guide groove 107h is formed on the side of the circular ring part 107d away from the protrusion 107b. The guide groove 107h is circular and surrounds the circumference of the circular ring part 107d. The guide rod 109 slides in the guide groove 107h, and the guide rod 109 is circular.

[0072] The protrusion 107b can slide along the circumference of the circular ring part 107d, and the first springs 107g serve as buffers and resetters. When the protrusion 107b rotates and abuts against the screen 106, the impact force of the protrusion 107b on the screen 106 is reduced, avoiding damage to the screen 106 and prolonging the service life of the screen 106.

[0073] The cover ring 110 is provided on the side of the annular portion 107d away from the protrusion 107b, and comprises a cover portion 110a and a mounting portion 110b. The cover portion 110a is annular and covers the side of the annular portion 107d. The mounting portion 110b is fixed on the connecting portion 107c by bolts. The connecting portion 107c is provided with an embedding groove 110c for the mounting portion 110b. A limiting block 110d is integrally formed at the opening of the embedding groove 110c. A limiting groove 110e is provided on the mounting portion 110b for the limiting block 110d. The mounting portion 110b is embedded in the connecting portion 107c, which facilitates positioning before bolt installation and improves the installation strength.
