It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0038] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0039] See also Figures 1 to 7 The embodiment of the present invention provides a construction waste crushing device, which includes a crushing box 1, wherein the upper and lower ends of the crushing box 1 are respectively provided with a feed port and a discharge port, an upper hopper 2 is installed at the feed port, a crushing mechanism 3 is also installed inside the crushing box 1, and a screen 4 is also elastically installed inside the crushing box 1, and the screen 4 covers the discharge port at the lower end of the crushing box 1;

[0040] A lower hopper 5 is also arranged at a position corresponding to the discharge port below the crushing box 1. The lower hopper 5 is arranged inclined, one end of which is rotatably connected to the crushing box 1 through a first hinged frame 6, and the other end is connected to the crushing mechanism 3 through a transmission member 7. A shock member 8 is also installed on the side of the crushing box 1 and the upper end of the lower hopper 5, and the shock member 8 can contact and collide with the screen 4.

[0041] It should be noted that: in the device, a support structure needs to be provided outside the crushing box 1, and the support is used to support the entire device to meet the use requirements;

[0042] When the residual material is crushed, the residual material to be crushed is put into the upper hopper 2, and then enters the crushing box 1. At this time, the crushing mechanism 3 can be turned on to crush the residual material; the crushed material that meets the particle size can pass through the screen 4 and fall into the lower hopper 5, while the crushed material that does not meet the particle size is further crushed;

[0043] One end of the lower hopper 5 is connected to the crushing box 1 through the first hinged frame 6, and is also connected to the crushing mechanism 3 through the transmission member 7. Therefore, during the operation of the crushing mechanism 3, the transmission member 7 can be used to drive the lower hopper 5 to reciprocate in the vertical direction with the first hinged frame 6 as the center, so that the crushed materials falling into the lower hopper 5 can be shaken to facilitate the discharge of the crushed materials.

[0044] The shock member 8 is set for the screen 4, and its structure for knocking the screen 4 is installed on the lower hopper 5, and the structure for positioning is installed on the crushing box 1. Therefore, when the lower hopper 5 rotates back and forth, it can drive the shock member 8 to reciprocate in the vertical direction. When the shock member 8 moves up and approaches the highest point, it can contact and collide with the screen 4; the screen 4 itself is elastically installed inside the crushing box 1, and when it is collided, it will vibrate. The vibration can also promote the discharge of materials, thereby further improving the efficiency of the crushing operation.

[0045] In the embodiments of the present invention, please refer to Figure 3 The crushing mechanism 3 includes a motor 31 installed on the side of the crushing box 1. The output end of the motor 31 is fixed with a main shaft 32 rotating inside the crushing box 1 through a coupling. Multiple sets of cutters 33 are installed on the main shaft 32.

[0046] It should be noted that when the crushing mechanism 3 is performing a crushing operation, the motor 31 directly drives the main shaft 32 to rotate, thereby driving the cutter 33 to move, and the cutter 33 is used to crush the residual material.

[0047] In the embodiments of the present invention, please refer to Figure 5 The screen 4 is composed of a mesh body 41 and a plate body 42. The mesh body 41 is arc-shaped, and the plate body 42 is composed of two pieces, which are symmetrically fixed inside the mesh body 41 and form a space for concentrating and crushing waste materials between the mesh body 41.

[0048] A spring 43 for supporting and positioning the screen 4 is also provided on one side of the plate body 42 , and legs 44 are fixed to the upper and lower ends of the spring 43 , the upper leg 44 is fixed to the plate body 42 , and the lower leg 44 is fixed to the inner wall of the crushing box 1 .

[0049] It should be noted that: the mesh body 41 is the main screening structure in the screen 4, and the setting of the plate body 42 can make the entire screen 4 more stable. The screen 4 itself is arc-shaped, so that it can better cooperate with the tool 33 to perform crushing operations. At the same time, a spring 43 is set on the side of the plate body 42, and the spring 43 is used to support the screen 4, and the entire screen 4 has a vibration function. Therefore, it is more convenient to screen out the crushed debris, and it can also ensure that there will be no blockage at this point.

[0059] It should be noted that: in the shock member 8, the first transmission rod 84 is installed on the lower hopper 5 through the second hinge frame 85. When the lower hopper 5 moves, it can also directly drive the first transmission rod 84 to move, and then drive the second transmission rod 87 to move. The second transmission rod 87 is restricted by the positioning cylinder 83, and its movement is a vertical movement. A knocking head 89 is provided at its upper end, and the knocking head 89 can knock the mesh body 41 to achieve vibration of the screen 4.
