Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1 and Figure 2 In this embodiment, a crusher with repeated crushing function includes a reinforcement frame 1, a hopper 2 is fixedly installed on the top of the reinforcement frame 1, an impact crusher 3 is fixedly installed on the upper surface of the reinforcement frame 1, the discharge port of the hopper 2 is connected to the output end of the impact crusher 3, and an inclined screening box 4 is welded on one side surface of the reinforcement frame 1 through a fixed frame. The top and bottom of the screening box 4 are both open structures, and a main belt 5 is welded on one side surface of the reinforcement frame 1 through a supporting frame. The main belt 5 is inclined and the lowest end is located below the output end of the impact crusher 3. A screening assembly is arranged inside the screening box 4, and a return material piece is arranged at the lowest end of the screening box 4.

[0020] Among them, a generator set 15 is fixedly installed on the upper surface of the reinforced frame 1 and located between the screening box 4 and the impact crusher 3, a control cabinet 16 is fixedly installed on one side surface of the reinforced frame 1, a walking track 17 is fixedly installed on the bottom of the reinforced frame 1, and a plurality of electric push rods 19 are fixedly installed on one end of the reinforced frame 1. An iron remover 18 is fixedly installed on the plurality of electric push rods 19, and the output end of the iron remover 18 is in contact with the upper surface of the main belt 5.

[0021] Among them, when the hopper 2 transports the construction waste to the inside of the impact crusher 3, the construction waste will be crushed inside the impact crusher 3, so that the crushed construction waste is transported to the inside of the screening box 4 through the main belt 5. At this time, the electric push rod 19 drives the iron remover 18 to move, so that the iron remover 18 can contact the construction waste on the main belt 5, thereby adsorbing metal products such as iron nails in the construction waste.

[0022] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the screening assembly includes a screen 6 slidably mounted on the inner wall of the screening box 4, a plurality of placement blocks 7 are fixedly mounted on the inner walls on both sides of the screening box 4, a plurality of spring telescopic rods 8 are fixedly mounted on the upper surfaces of the plurality of placement blocks 7, the upper surfaces of the plurality of spring telescopic rods 8 are fixedly connected to the upper surface of the screen 6, a screen belt 14 is welded to the bottom of the screening box 4 through a mounting frame, and a vibrating member that can drive the screen 6 to vibrate is arranged below the screen 6.

[0023] Among them, the vibrating member includes a protective box fixedly mounted on the surface of one side of the screening box 4, a motor 9 is fixedly mounted on the inner wall of the protective box, and a rotating shaft 10 is fixedly mounted on the output end of the motor 9, one end of which extends to the inside of the screening box 4 and is rotatably connected to the inner wall of one side of the screening box 4, and a plurality of eccentric wheels 11 are fixedly mounted on the surface of the rotating shaft 10, and the protruding ends of the plurality of eccentric wheels 11 are in contact with the lower surface of the screen 6.

[0024] The motor 9 drives the rotating shaft 10 to rotate, so that the rotating shaft 10 can drive the eccentric wheel 11 to rotate, so that the protruding end of the eccentric wheel 11 can contact the upper surface of the screen 6, so that the screen 6 moves upward as a whole. When the protruding end of the eccentric wheel 11 no longer contacts the upper surface of the screen 6, the screen 6 is reset under the drive of the spring telescopic rod 8, so that the screen 6 generates a vibration force in an instant, thereby vibrating the construction waste on the upper surface of the screen 6, avoiding the accumulation of construction waste on the upper surface of the screen 6, and allowing construction waste that meets the standards to pass through the screen 6 and fall on the upper surface of the under-screen belt 14, and be transported to the outside through the under-screen belt 14, thereby reusing such construction waste.

[0025] See also Figure 1 and Figure 2 In this embodiment, the return material part includes a return material belt 12 welded to the reinforcement frame 1 through a connecting frame.

One end of the return material belt 13 is located below the return material belt 12, and the other end of the return material belt 13 is located above the hopper 2.

[0026] The construction waste that does not meet the standards falls onto the upper surface of the return belt 12 through the inclined setting of the screen 6, and is transported by the return belt 12 to the return belt 13, and is transported to the inside of the hopper 2 through the return belt 13, and is transported by the hopper 2 to the inside of the impact crusher 3 for secondary crushing, so that the construction waste can meet the standards.

[0027] It should be noted that the main belt 5, the return belt 12, the return belt 13 and the under-screen belt 14 are all provided with driving devices to provide power for the movement of the belts, and the driving device of the belts is a prior art, and its specific structure and working principle are not described in detail in this article.

[0028] The working principle of the above embodiment is as follows: the motor 9 drives the rotating shaft 10 to rotate, so that the rotating shaft 10 can drive the eccentric wheel 11 to rotate, so that the protruding end of the eccentric wheel 11 can contact the upper surface of the screen 6, so that the screen 6 moves upward as a whole. When the protruding end of the eccentric wheel 11 is no longer in contact with the upper surface of the screen 6, the screen 6 is reset under the drive of the spring telescopic rod 8, so that the screen 6 generates a vibration force in an instant, thereby vibrating the construction waste on the upper surface of the screen 6, avoiding the accumulation of construction waste on the upper surface of the screen 6, and allowing construction waste that meets the standards to pass through the screen. 6, thereby falling on the upper surface of the under-screen belt 14, and being transported to the outside through the under-screen belt 14, so as to reuse this type of construction waste. The construction waste that does not meet the standards passes through the inclined setting of the screen 6, thereby falling on the upper surface of the return belt 12, and is transported by the return belt 12, thereby being transported to the return belt 13, and is transported to the inside of the hopper 2 through the return belt 13, and is transported again by the hopper 2 to the inside of the impact crusher 3 for secondary crushing, so that the construction waste can meet the standards, and the device can crush the construction waste multiple times until the crushed construction waste meets the secondary utilization standards.

[0029] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.
