Description

Technical Field

[0001] This utility model belongs to the field of construction waste sorting technology and relates to a construction waste sorting device. Background Technology

[0002] Construction waste refers to the general term for slag, waste concrete, waste bricks and stones, and other waste generated during the production activities of the construction industry, such as demolition, construction, decoration, and repair. According to the source of generation, construction waste can be divided into engineering slag, decoration waste, demolition waste, engineering mud, etc. According to the composition, construction waste can be divided into slag, concrete blocks, crushed stone blocks, brick and tile fragments, waste mortar, mud, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc. When construction waste is used, it needs to be processed by sorting equipment.

[0003] Existing Chinese patent CN222642117U discloses a waste sorting device for construction, relating to the field of construction waste sorting technology. The device includes a main body with a feeding port at its top. A first threaded rod is rotatably connected to the inner wall of the feeding port. One end of the first threaded rod is fixedly connected to a first servo motor. By setting the first threaded rod, when construction waste is being sorted by the waste sorting device, in order to improve the cleaning effect of the crushing roller on the cloth and lint on the surface of the construction waste, prevent the cloth from adhering to the surface of the crushing roller and causing jamming, and prevent reducing the crushing effect of the crushing roller on subsequent stones, the first servo motor can be turned on when cleaning is needed. The rotation of the first threaded rod drives a lifting box to slide along the inner wall of the chute. The movement of the lifting box causes the crushing roller to rise and fall from the feeding port, thus facilitating the cleaning of the cloth and lint on the surface of the crushing roller.

[0004] However, the aforementioned device still requires manual shutdown during operation to clean the flexible waste materials such as cloth and velvet from the surface of the crushing rollers. This cleaning process is cumbersome. Furthermore, the screening mechanism is inefficient and inconvenient to maintain. The first filter screen only achieves screening through sliding driven by the second threaded rod, lacking vibration assistance, leading to waste accumulation and "clogging." The second filter screen is driven unidirectionally by an electric push rod, with a single movement trajectory (only linear reciprocating), failing to adequately disperse waste and resulting in low screening efficiency. Additionally, replacement requires disassembling numerous parts, and the lack of vibration assistance during screening leads to material accumulation and incomplete screening. Therefore, this utility model provides a construction waste sorting device to solve the above problems. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model discloses a construction waste sorting device. The technical solution adopted is as follows: it includes a frame, the frame including front and rear upright plates, a crushing frame fixedly installed on the top of the front and rear upright plates, a crushing mechanism installed in the crushing frame, the crushing mechanism including crushing rollers symmetrically arranged on the left and right sides of the front and rear side walls of the crushing frame, the surfaces of the left and right crushing rollers respectively having a circumferential array of interlocking semi-ellipsoidal roller teeth, the left and right crushing rollers being driven by interlocking gears on a rotating shaft passing through the front wall of the frame, the lower part of the left and right crushing rollers respectively having scrapers, the upper edge of the scrapers having notches adapted to the semi-ellipsoidal roller teeth, the front and rear ends of the left and right scrapers respectively being fixedly installed with L-shaped fixing columns, the L-shaped fixing columns being fitted with springs, the lower part of the L-shaped fixing columns being movably inserted into fixing ears installed in corresponding positions inside the crushing frame, the right crushing roller being driven by a driving mechanism installed on the right side wall of the crushing frame on a rotating shaft passing through the front wall of the frame, and a screening mechanism being installed between the front and rear upright plates.

[0006] As a preferred embodiment of this utility model, the left and right side walls of the upper feed inlet of the crushing frame are respectively inclined towards the corresponding crushing rollers and are provided with guide plates; by using guide plates, large particles of construction waste are prevented from getting stuck in the gaps between the crushing rollers and the sides of the crushing frame.

[0007] As a preferred embodiment of this utility model, the driving mechanism includes a first pulley fixedly mounted on the rear end of the shaft of the right crushing roller, a belt mounted on the first pulley, the right end of the belt mounted on a second pulley, the second pulley fixedly mounted on the output shaft of a first motor, and the first motor mounted on the right outer wall of the crushing frame via an L-shaped mounting bracket.

[0008] As a preferred embodiment of this utility model, L-shaped notches are symmetrically opened at the upper left edge and the lower right edge of the front and rear upright plates, respectively; by using L-shaped notches, it is convenient to quickly remove the screen for replacement.

[0009] In a preferred embodiment of this utility model, the L-shaped notches on the left front and right sides are rotatably inserted into the front and rear ends of the upper and lower screening mechanisms, respectively. The screening mechanism includes a rotating tube rotatably inserted into the L-shaped notches. An inclined screen is fixedly connected downward on one side of the rotating tube. The end of the screen is connected to a horizontal discharge plate. A rotating shaft is rotatably inserted into the front and rear vertical wall opposite the lower part of the screen near the discharge plate. Eccentric wheels that slide in contact with the lower front and rear edges of the screen are fixedly fitted at the front and rear ends of the rotating shaft, respectively. The front end of the rotating shaft is fixedly connected to the output shaft of a second motor installed on the outside of the vertical plate. By using the second motor to drive the corresponding rotating shaft to rotate, the corresponding eccentric wheel is driven to rotate, causing the lower part of the screen above the eccentric wheel to be lifted upwards at a high frequency, thereby amplifying the vibration of the screen and achieving the purpose of rapid screening.

[0010] As a preferred embodiment of this utility model, the upper screen is set with the left side higher than the right side, and its left end is fixedly connected to the rotating tube on the left side; the lower screen is set with the left side lower than the right side, and its right end is fixedly connected to the rotating tube on the right side; the mesh size of the upper and lower screens decreases sequentially.

[0011] The beneficial effects of this utility model are:

[0012] The semi-ellipsoidal roller teeth of the left and right crushing rollers in the crushing mechanism mesh with each other to ensure that the construction waste is crushed thoroughly. At the same time, the scraper directly below the crushing roller has a notch that matches the roller teeth and achieves elastic contact with the spring on the L-shaped fixing column. This can remove the flexible waste material remaining on the surface of the roller teeth in real time and avoid tangling and jamming.

[0013] The screening mechanism uses a second motor to drive the rotating shaft, which in turn drives the eccentric wheel to rotate, causing the screen to vibrate at high frequency. This effectively disperses waste and significantly improves screening efficiency. The mesh size of the upper and lower screens decreases sequentially, enabling material grading and sorting. The discharge plate ensures that the material is discharged in an orderly manner. The L-shaped notches on the front and rear vertical plates facilitate quick disassembly and assembly of the rotating tube, thereby enabling convenient screen replacement and reducing maintenance costs.
