DETAILED DESCRIPTION

[0022] The utility model provides a device for cleaning and recovering cement on the surface of wood waste, such as Figure 1-3As shown, it includes a base 11, a screening chamber 12, an upper bracket 13, a connecting bracket 14, a shaking screen 15, a blower 16, a blast channel 17, a main sliding plate 20, a first opening 21, a first rotating shaft 22, a motor 23, a rotating roller 24, a first slider 25, a sliding slot 26, a second opening 27, a screw 28, and a rotating block 29.

[0023] like Figure 1-3 As shown, a screening chamber 12 is provided in the base 11, a plurality of connecting brackets 14 are fixedly connected to the upper bracket 13, the connecting brackets 14 are fixedly connected to the base 11, two main sliding plates 20 are slidably connected to the upper bracket 13, both ends of the main sliding plates 20 are fixedly connected to the limiting components, a plurality of first openings 21 are provided on the main sliding plates 20, a crushing component is rotatably connected in the first openings 21, a blower 16 is fixedly connected to the base 11, a blast channel 17 is fixedly connected to the blower 16, an air outlet of the blast channel 17 is arranged between the base 11 and the upper bracket 13, and the first openings 21 are arranged at equal distances.

[0024] The crushing assembly includes a first rotating shaft 22 and a motor 23. The first rotating shaft 22 is rotatably connected to the first opening 21. The motor 23 is fixedly connected to the main sliding plate 20. The output shaft of the motor 23 is fixedly connected to the first rotating shaft 22. A rotating roller 24 is fixedly connected to the outer circumferential surface of the first rotating shaft 22. The length of the rotating roller 24 is less than the distance between the base 11 and the upper bracket 13.

[0025] The limiting assembly includes a first slider 25 and a screw 28. The first slider 25 is provided with a sliding groove 26 and a second opening 27. The screw 28 is threadedly connected to the second opening 27. The end of the screw 28 away from the main sliding plate 20 is fixedly connected to a rotating block 29. A shaking screen 15 is arranged in the screening chamber 12. The shaking screen 15 is the existing technology. A plurality of sieve holes are arranged on the shaking screen 15, and a plurality of protrusions are arranged on the rotating roller 24.

[0026] When the present scheme is used to clean and recycle cement on the surface of wood waste, first, the first sliders 25 on both sides of the upper bracket 13 are pushed along the upper bracket 13. After the first sliders 25 drive the main sliding plate 20 to translate until the distance between the two main sliding plates 20 is adapted to the width of the wood to be cleaned and recycled, the rotating block 29 is rotated to move the screw 28 toward the second opening 27, so that the screw 28 fixes the first slider 25 and the upper bracket 13.

[0027] Then, the wood is placed between the rotating rollers 24 on the two main sliding plates 20, and the motor 23 and the blower 16 are started. The output shaft of the motor 23 drives the first rotating shaft 22 to rotate, and the first rotating shaft 22 drives the rotating roller 24 to rotate with the first rotating shaft 22 as the axis core. The protrusions on the rotating roller 24 rub and knock down the cement on the surface of the wood. When the cement on the surface of the wood is rubbed and knocked off, wood chips will also be knocked off at the same time.

[0028] Finally, the blower 16 blows air through the blowing channel 17 to quickly flow between the base 11 and the upper bracket 13. When the air flows between the base 11 and the upper bracket 13, the fine wood chips adhering to the cement are blown away, and the shaking screen 15 is started. The shaking screen 15 screens the large wood chips in the mixture of cement and large wood chips into the space below the shaking screen 15.
