[0017] The present invention will be further described in detail below with reference to embodiments: like Figures 1-5 As shown, this utility model provides a concrete scrap crushing device, including a base 1, a base frame 2 symmetrically fixedly installed on both sides of the top of the base 1, a top plate 3 fixedly installed on the top of the base frame 2, a crushing box 4 fixedly connected to the upper end of the top plate 3, a separation mechanism 5 provided inside the lower end of the crushing box 4, a screening mechanism 6 provided below the top plate 3, a collection frame 7 movably installed in the middle of the upper end of the base 1, a controller 8 fixedly connected to the left end of the crushing box 4, a connected feed frame 9 fixedly installed on the top of the crushing box 4, and a cover 10 hinged to the top of the feed frame 9.

[0018] The upper two inner walls of the crushing box 4 are symmetrically fixed with fixing blocks 11, and the inner sides of the fixing blocks 11 are symmetrically rotatably mounted with crushing rollers 12. The lower two inner walls of the crushing box 4 are symmetrically fixed with inclined platforms 13. The lower middle part of the top plate 3 is fixedly connected with a discharge port 14. The rear side of the crushing box 4 is fixedly connected with a side frame 16, and the inner side of the side frame 16 is fixedly connected with a motor 17. The rear ends of the two sets of crushing rollers 12 are both driven by gears 18.

[0019] The discharge port 14 is connected to the interior of the crushing box 4, and the top of the output rod of motor 2 17 is fixedly connected to the front end of the left gear 18.

[0020] Two sets of gears 18 mesh with each other, and the discharge port 14 is located directly above the screening frame 66.

[0021] In this scheme, the baffle 10 can block the dust generated by the concrete scrap during crushing, preventing the dust from spreading to the outside through the feed frame 9. The inclined platform 13 can guide the crushed scrap, ensuring that the crushed scrap falls into the screening frame 66 at the bottom through the discharge port 14.

[0022] like Figure 4 As shown, the separation mechanism 5 includes a limiting frame 51. The outside of the limiting frame 51 is fixedly connected to the lower inner wall of the crushing box 4. An installation frame 52 is movably installed on the upper end of the limiting frame 51. Multiple sets of fixedly connected magnets 53 are distributed equidistantly inside the installation frame 52. A through groove 54 is opened through the front end of the crushing box 4. An end plate 55 is movably installed inside the through groove 54. Bolts 56 are movably inserted into both sides of the end plate 55. Screw holes 57 are symmetrically opened on both sides of the front end of the crushing box 4.

[0023] The mounting frame 52 is internally movable to the through groove 54, and the bolt 56 is threaded to the screw hole 57.

[0024] In this solution, by loosening the bolt 56 from the screw hole 57, the end plate 55 can be removed, making it easy to pull the mounting frame 52 out of the limit frame 51 through the through groove 54, so as to facilitate the collection of the metal parts adsorbed on the magnet 53.

[0025] like Figure 5As shown, the screening mechanism 6 includes a horizontal plate 61. Both ends of the horizontal plate 61 are fixedly connected to the inner middle of the base frame 2. A vertical shaft 62 is rotatably installed at the middle of the right end of the horizontal plate 61. A cam 63 is fixedly connected to the top of the vertical shaft 62. Slide grooves 64 are provided on both the front and rear sides of the upper end of the horizontal plate 61. A slider 65 is limited and slidably installed inside the slide groove 64. A screening frame 66 is fixedly connected to the top of the slider 65. A fixing frame 67 is fixedly installed at the middle of the upper end of the base frame 2 on the left end. Telescopic rods 68 are fixedly connected to both sides of the top of the fixing frame 67. A spring 69 is sleeved on the outside of the telescopic rod 68. A stop plate 610 is fixedly connected to the top of the telescopic rod 68.

[0026] A through opening is provided in the middle of the horizontal plate 61, the protrusion of the cam 63 is movably connected to the right side of the screening plate, and the front end of the abutment plate 610 is movably connected to the left side of the screening frame 66.

[0027] A through opening is provided in the middle of the horizontal plate 61, the protrusion of the cam 63 is movably connected to the right side of the screening plate, and the front end of the abutment plate 610 is movably connected to the left side of the screening frame 66.

[0028] In this design, an opening is provided through the middle of the horizontal plate 61, and suitable scraps after screening can fall into the collection frame 7 through the opening. The slider 65 slides in the chute 64, thereby ensuring the stability of the horizontal movement of the screening frame 66.

[0029] The working principle of this concrete scrap crushing device will be explained in detail below.

[0030] like Figures 1-5As shown, when the concrete scrap crushing device is in use, starting motor 17 drives the left gear 18 to rotate, which in turn drives the meshing right gear 18 to move synchronously. The two rotating gears 18 drive the two crushing rollers 12 to rotate in opposite directions. Concrete scrap can then be fed into the crushing box 4 through the feed frame 9, falling between the two crushing rollers 12. The crushing rollers 12 crush the scrap, which then falls into the mounting frame 52. Multiple magnetic rods 53 in the mounting frame 52 attract any remaining metal parts in the scrap, which then fall through the gaps between the magnetic rods 53 into the screening frame 66 below via the discharge port 14. Finally, starting motor 15 causes the cam 63 to rotate via the vertical shaft 62, causing the cam 63's convex... The starting part pushes the screening frame 66 to the right, so that the screening plate contacts the abutment plate 610 and pushes the abutment plate 610 to move synchronously. This causes the abutment plate 610 to squeeze the telescopic rod 68 and the spring 69 simultaneously. When the protrusion of the cam 63 separates from the screening frame 66, the screening frame 66 is pulled to the left by the elastic restoring force of the spring 69 and begins to move to the left. At this time, the cooperation between the slider 65 and the groove 64 at the bottom of the screening frame 66 ensures that the screening frame 66 can slide back and forth along the predetermined straight line. During the back and forth sliding of the screening frame 66, the crushed scrap inside it also tumbles continuously. Since the screen of the screening frame 66 has a specific aperture size, the qualified crushed scrap with a particle size smaller than the screen aperture will gradually pass through the screen under the dual action of gravity and vibration and fall into the collection frame 7 below, thus completing the collection.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
