[0027] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model proposes a concrete recycling device for engineering applications, including a shell 1, a frame 3 hinged to the upper end of the shell 1, a sliding plate 515 with a groove 516, a rotating plate 517 sleeved on the groove 516, the rotating plate 517 being rotatably connected to the inner wall of the shell 1, a cover plate 4 inserted into the frame 3, a discharge port 2 at the lower end of the shell 1, and a crushing device inside the shell 1.

[0030] In an embodiment of this utility model, in order to crush concrete, the crushing device specifically includes a crushing roller 51, which penetrates the housing 1 and is rotatably connected to the housing 1. The crushing roller 51 is meshed with a gear 53, and a transmission wheel 54 is fixedly connected to the outer wall of the gear 53. The transmission wheel 54 is fixedly connected to the output end of the motor 55. The crushing roller 52 is sleeved with the housing 1. The shaft of the crushing roller 52 penetrates the bearing 521 and is fixedly connected to the bearing 521. The outer wall of the bearing 521 is fixedly connected to the output end of the hydraulic cylinder 59. The transmission belt 56 is connected to the crushing roller 52 and the transmission wheel 54 respectively. The pressure wheel 57 is connected to the transmission belt 56. A guide rod 58 is fixedly connected to the outer wall of the pressure wheel 57. The guide rod 58 is slidably connected to the outer wall of the housing 1. The guide rod 58 is elastically connected to the outer wall of the housing 1 through a spring.

[0031] Furthermore, the shaft of the crushing roller 51 passes through the cam 513, the cam 513 has a slot 514, the shaft of the crushing roller 51 passes through the fixed sleeve 511, the fixed sleeve 511 is slidably connected to the elastic block 512, a movable plate 515 is provided above the cam 513, the movable plate 515 is slidably connected to the outer wall of the housing 1, the movable plate 515 has a sliding groove 516, the sliding groove 516 is sleeved with a rotating plate 517, and the rotating plate 517 is rotatably connected to the inner wall of the housing 1.

[0032] In this invention, during use, concrete fragments are first placed on the outer wall of the cover plate 4. The cover plate 4 then opens downwards under gravity, causing the concrete fragments to fall onto the outer walls of the first crushing roller 51 and the second crushing roller 52. When the force on the cover plate 4 disappears, the cover plate 4 returns to its original position under the action of the elastic telescopic rod 11, thereby closing the housing 1 and preventing dust from splashing during concrete crushing. Then, the motor 55 is started. When the motor 55 starts, the concrete fragments pass through the gear 53, the transmission wheel 54, and the transmission belt 5... Driven by the transmission of the 6, the first crushing roller 51 and the second crushing roller 52 rotate synchronously, causing them to crush the concrete. When it is necessary to adjust the distance between the first crushing roller 51 and the second crushing roller 52, the hydraulic cylinder 59 is activated. When the hydraulic cylinder 59 is activated, the second crushing roller 52 moves towards the edge of the housing 1 under the force of the hydraulic cylinder 59, thereby adjusting the distance between the first crushing roller 51 and the second crushing roller 52. It should be noted that when the second crushing roller 52 moves, the transmission... The drive belt 56 applies a force to the pressure roller 57, causing the pressure roller 57 to move upwards. Simultaneously, the spring undergoes elastic deformation. When the crushing roller 52 returns to its original position, the pressure roller 57, under the elastic force of the spring, applies a force to the drive belt 56. The design of the pressure roller 57 ensures that the drive belt 56 remains taut. When the drive motor 55 rotates in the opposite direction, the right-angled side of the elastic locking block 512, which is slidably connected to the fixed sleeve 511, applies a force to the locking groove 514, causing the cam 513 to synchronously... When the cam 513 rotates, it applies a force to the moving plate 515, causing the moving plate 515 to move upward. When the force from the cam 513 to the moving plate 515 disappears, the moving plate 515 returns to its original position under the action of gravity. Through the action of the moving plate 515, the cam 513 and the slide 516, the rotating plate 517 swings back and forth against the inner wall of the housing 1, thereby pushing the concrete inside the housing 1 toward the center and improving the efficiency of concrete crushing.
