[0002] Construction waste refers to the waste generated during construction, demolition, and renovation, mainly including slag, waste concrete, waste bricks and stones, waste mortar, and waste wood. If these wastes are not properly disposed of, they will have adverse effects on the environment and resources.

[0003] Chinese Patent Publication No. CN221310953U discloses a construction waste recycling device, including a main body of the recycling device. This device, through the cooperation of the main body and a first drive motor, utilizes a first rotating rod to drive a first crushing roller to rotate. Simultaneously, the outer walls of a first gear and a second gear mesh with each other, enabling the first and second crushing rollers to perform a first-stage crushing of the construction waste. After crushing, the waste falls onto the surface of a screening plate, thus isolating larger pieces of construction waste.

[0004] While the above solutions can isolate large construction waste, the recycling device in the above patent has difficulty adjusting the discharge position. When the third crushing roller of the above patent further crushes large construction waste, the crushed construction waste has poor fluidity and tends to accumulate directly below the third crushing roller and gradually cover it, which will cause the rotation of the third crushing roller to be obstructed or even completely blocked. Therefore, we provide a construction waste recycling device to solve the above problems. Summary of the Invention

These specific embodiments can be combined or substituted with each other according to actual conditions. Identical or similar concepts or processes may not be described again in some embodiments. Embodiment 1 like Figures 1 to 5 As shown, this utility model provides a construction waste recycling device, including a protective shell 1, a crushing chamber 11, a receiving chamber 19, and a regulating shell 2. The crushing chamber 11 is disposed on the top of the protective shell 1, and the receiving chamber 19 is placed at the bottom of the inner cavity of the protective shell 1. The protective shell 1, the crushing chamber 11, and the receiving chamber 19 are arranged in a connected manner. The regulating shell 2 is fixedly disposed on one side of the protective shell 1. The crushing chamber 11 is provided with a crushing assembly for crushing waste materials. The crushing assembly includes a second motor 13, two first crushing rollers 14, and two first gears 15. The two ends of the two first crushing rollers 14 are respectively connected to the two sides of the inner cavity of the crushing chamber 11 through bearings, and one end of the two first crushing rollers 14 is respectively connected to two... The middle of the first gear 15 is fixedly connected, and the outer teeth of the two first gears 15 mesh with each other. The second motor 13 is fixedly installed on one side of the crushing chamber 11 opposite to the two first gears 15. The output shaft of the second motor 13 is connected to one of the first crushing rollers 14. The first motor 3 is fixedly installed on the inner wall of the control housing 2. The output shaft of the first motor 3 is connected to the drive rod 4. The drive rod 4 is hinged to the power connecting rod 5. The power connecting rod 5 is hinged to the control plate 6. The control plate 6 is fixedly connected to the central control single shaft 7. The flow control plate 8 is fixedly connected to the outer circumference of the central control single shaft 7. The flow control plate 8 is set inside the protective housing 1. The two ends of the central control single shaft 7 are rotatably connected to the control housing 2 and the protective housing 1 respectively through bearings.

[0017] The second motor 13 drives one of the first crushing rollers 14 to rotate, and the external teeth of the two first gears 15 mesh with each other to make the two first crushing rollers 14 rotate in opposite directions, thereby crushing the construction waste. By starting the first motor 3, the drive rod 4 rotates, which causes the power linkage 5 to drive the control plate 6 to swing, causing the central control single shaft 7 to move synchronously. The tilt angle of the flow control plate 8 will change synchronously, discharging the crushed construction waste into a reasonable position in the receiving bin 19, avoiding the accumulation of waste fragments that may cause blockage of the crushing components.

[0018] Furthermore, to enhance the drainage effect, there are two central control shafts 7, each fixedly connected to a flow control plate 8. One central control shaft 7 is fixedly connected to the control plate 8 and a main plane sprocket 9 is fixedly connected to its outer circumference. The main plane sprocket 9 meshes with a linkage chain 10, which also meshes with a secondary plane sprocket 20. The secondary plane sprocket 20 is fixedly connected to the other central control shaft 7. Through the transmission of the sprockets and chains, the two flow control plates 8 rotate at the same tilt angle.

[0019] Furthermore, a feed hopper 12 is provided above the crushing chamber 11, and the feed hopper 12 has an inverted frustum-shaped opening that communicates with the crushing chamber 11. The inverted frustum-shaped opening facilitates the sliding in of construction waste materials, preventing them from falling directly and impacting the device.

[0020] Furthermore, the crushing assembly also includes a third motor 16, two second crushing rollers 17, and two second gears 18. The two second crushing rollers 17 are positioned below the first crushing roller 14, and their two ends are respectively connected to both sides of the inner cavity of the crushing chamber 11 via bearings. One end of each of the two second crushing rollers 17 is fixedly connected to the middle of the two second gears 18, and the external teeth of the two second gears 18 mesh with each other. The third motor 16 is fixedly mounted on one side of the crushing chamber 11 opposite to the two second gears 18, and the output shaft of the third motor 16 is connected to one of the second crushing rollers 17. The distance between the two second crushing rollers 17 is smaller than the distance between the two first crushing rollers 14. By setting two second crushing rollers 17 to perform secondary crushing of the construction waste, and with a smaller distance between the two second crushing rollers 17, large fragments are prevented from remaining in the crushed construction waste.

[0021] Furthermore, the protective outer shell 1 is inserted into the receiving chamber 19. This insertion method allows the receiving chamber 19 to be easily removed from the inner cavity of the protective outer shell.

[0022] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
