[0002] Construction waste refers to the muck, waste soil, waste materials, silt and other waste generated during the construction, laying or demolition and repair of various buildings, structures, pipe networks, etc. by construction units or individuals. When dealing with construction waste, it is often necessary to screen out small pieces of garbage and powdery garbage mixed in large pieces of construction waste.

[0003] Common construction waste screening structures are generally composed of multiple layers of sieve meshes. The separation of large and small pieces of garbage is achieved by pouring garbage into the sieve meshes. However, as the construction waste accumulates continuously, the larger garbage still occupies a large area of the entire filter mesh, affecting the subsequent garbage separation efficiency. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a construction waste screening device, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: including: a garbage screening box and a screening filter mesh installed in the cavity of the garbage screening box.

[0006] It further includes:

[0007] A moving horizontal shaft is arranged above the screening filter mesh. A plurality of groups of scraping cylinders are installed on the surface of the moving horizontal shaft at intervals. A scraping plate part is fixedly arranged on the opposite side of the moving horizontal shaft with respect to the scraping cylinders.

[0008] A moving limit block is fixedly arranged at one end of the moving horizontal shaft.

[0009] A moving connection frame is installed above the moving limit block. Corresponding positioning insertion holes are opened in the moving limit block and the moving connection frame. A limit insertion rod part is inserted into the holes of the positioning insertion holes.

[0010] A driving mechanism is arranged below the moving connection frame. The transmission mechanism drives the moving connection frame to move horizontally along the bottom surface of the garbage screening box.

[0011] Further, one end of the moving horizontal shaft far from the moving limit block is rotatably connected with a rotating support shaft. A limit horizontal groove part is opened on the inner wall of the garbage screening box. A slider is arranged at one end of the rotating support shaft far from the moving horizontal shaft.

[0012] Further, the scraping cylinder is connected with the moving horizontal shaft through a rotating shaft.

[0013] Further, a horizontal groove is opened on the outer wall of the garbage screening box. A moving block extending into the chute is fixedly arranged on the side wall of the moving connection frame.

[0014] Further, a perforation allowing the transverse movement of the transverse movement shaft is formed on the side wall of the garbage screening box.

[0015] Further, the driving mechanism includes an adjusting screw rod and a meshing kit. The adjusting screw rod is installed below the moving limit block. The meshing kit is meshed and sleeved outside the adjusting screw rod. The surface of the meshing kit is fixed to the moving connection frame through a support rod.

[0016] Further, a screening baffle is buckled on the top of the garbage screening box. The inner wall of the garbage screening box is connected with a side cover plate through a rotating shaft. A shielding support plate is fixedly arranged on the surface of the garbage screening box on the same side as the side cover plate.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] Through the designed driving mechanism of the present application, the transverse movement shaft can move transversely in the cavity of the garbage screening box, so that the scraping cylinders distributed at intervals can move repeatedly above the screening filter net. Therefore, the garbage can be spread as much as possible above the screening filter net, improving the screening efficiency of construction waste. At the same time, by rotating the use angle of the transverse movement shaft to make the scraping part face downward, the garbage can be pushed to one side through the transverse movement of the scraping part, thereby reducing the occupied area of the garbage, facilitating subsequent continuous screening, and further improving the screening efficiency.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-3 , including: a garbage screening box 1 and a screening filter net 3 installed in the cavity of the garbage screening box 1. Two groups of screening filter nets 3 are arranged in the cavity of the garbage screening box 1. The screen hole diameters of each group of screening filter nets 3 are different, and can respectively correspond to screening construction waste of different sizes. When garbage is put in at the opening of the garbage screening box 1, through the construction waste, under the action of gravity, it respectively passes through the two groups of screening filter nets 3, and different construction wastes stay above different screening filter nets 3. The garbage that completely passes through the two groups of screening filter nets 3 is discharged from the bottom of the garbage screening box 1. A screening baffle 2 is buckled and installed above the top opening of the garbage screening box 1, and the screening baffle 2 can increase the space at the top of the garbage screening box 1.

[0025] The moving horizontal axis 4 is horizontally installed above the screening filter net 3. A number of groups of scraping cylinders 7 are installed on the surface of the moving horizontal axis 4 at intervals. A scraping plate part 8 is fixedly arranged on the opposite side of the moving horizontal axis 4 with respect to the scraping cylinder 7. The scraping plate part 8 and the scraping cylinder 7 are symmetrically distributed on the outer wall of the moving horizontal axis 4. The scraping cylinder 7 is connected to the moving horizontal axis 4 through a rotating shaft, so that the scraping cylinder 7 can rotate freely. When the moving horizontal axis 4 moves radially in the cavity of the garbage screening box 1, the accumulated garbage can be spread out through the gap between the two scraping cylinders 7, improving the filtering efficiency. When the scraping plate part 8 is at the lower position of the moving horizontal axis 4, the garbage can be pushed to one side through the scraping plate part 8. In this way, the larger garbage accumulated above the screening filter net 3 can be pushed to one side, reducing the occupied space of the larger block of garbage and facilitating subsequent garbage screening;

[0026] The side wall of the garbage screening box 1 is provided with a perforation allowing the transverse movement of the moving horizontal shaft 4. One end of the moving horizontal shaft 4 passes through the perforation and extends outward and is fixedly provided with a moving limit block 9, so that the moving horizontal shaft 4 and the moving limit block 9 can move synchronously. In order to improve the stability of the movement of the moving horizontal shaft 4, a rotating support shaft 5 is rotatably connected to the end of the moving horizontal shaft 4 away from the moving limit block 9. A limiting horizontal groove portion 6 is provided on the inner wall of the garbage screening box 1. A slider is provided at the end of the rotating support shaft 5 away from the moving horizontal shaft 4. The slider moves in the groove of the limiting horizontal groove portion 6, which can provide stable support for the movement of the moving horizontal shaft 4. The moving connection frame 10 is installed above the moving limit block 9. Corresponding positioning insertion holes 11 are provided in the moving limit block 9 and the moving connection frame 10. A limiting insertion rod portion 12 is inserted into the hole of the positioning insertion hole 11. The moving connection frame 10 is longitudinally combined with the positioning insertion hole 11 through the limiting insertion rod portion 12, so that the moving connection frame 10 and the moving limit block 9 can move synchronously. The positioning insertion hole 11 adopts a penetrating design for the moving limit block 9. Therefore, after the moving horizontal shaft 4 rotates, only by inserting the limiting insertion rod portion 12 into the positioning insertion hole 11, the use angle of the moving horizontal shaft 4 can be fixed. A horizontal groove is provided on the outer wall of the garbage screening box 1. A moving block extending into the chute is fixedly provided on the side wall of the moving connection frame 10. The movement direction of the moving connection frame 10 can be restricted through the horizontal groove and the moving block, improving the movement stability of the moving connection frame 10;

[0027] The driving mechanism is arranged below the moving connection frame 10. The transmission mechanism drives the moving connection frame 10 to move horizontally along the bottom surface of the garbage screening box 1. The driving mechanism includes an adjusting screw 13 and a meshing kit 14. The adjusting screw 13 is installed below the moving limit block 9. The meshing kit 14 is meshed and sleeved outside the adjusting screw 13. The surface of the meshing kit 14 is fixed to the moving connection frame 10 through a support rod. One end of the adjusting screw 13 is connected to a motor, and the other end is provided with a support plate. When the motor drives the adjusting screw 13 to rotate, the meshing kit 14 can move radially, and at the same time drive the moving limit block 9 to move horizontally on the side wall of the garbage screening box 1, so that the moving horizontal shaft 4 moves horizontally above the screening filter net 3. The inner wall of the garbage screening box 1 is connected with a side cover plate 17 through a rotating shaft. A shielding support plate 16 is fixedly provided on the surface of the garbage screening box 1 on the same side as the side cover plate 17. After the garbage is pushed to one side position above the screening filter net 3, the garbage can fall on the shielding support plate 16 for collection by opening the side cover plate 17.
