Background technique

Construction waste refers to the general term for slag, waste concrete, waste bricks and other wastes generated by people in the production activities of the construction industry such as demolition, construction, decoration, and repair. According to the different sources of construction waste, it can be divided into construction waste and demolition waste. The construction waste generated by the demolition of old buildings includes bricks, rubble, concrete blocks, metals, plastic products, and wood. When recycling construction waste, it is necessary to use a crusher to break it into fragments, so as to facilitate secondary use and storage in the later stage.

When the screening drum 4 rotates under the action of the first drive motor 11, the connecting shaft 13 on the other side can rotate smoothly in the bearing seat 12, thereby further enhancing the stability of the overall equipment.

As shown in Figure 3, the screening drum 4 is arranged at an angle, and the two sides of the screening drum 4 are respectively provided with a feed port 5 and a discharging port 21. The higher side of the screening drum 4 is the feed port 5, and the construction waste fragments can enter the screening drum 4 through the feed port 5. The lower side of the screening drum 4 is the discharging port 21. The construction waste fragments with larger particles after screening by the screening drum 4 can be taken out from the discharging port 21. A discharging baffle 22 is arranged outside the discharging port 21, and the discharging baffle 22 is rotatably installed on the first chassis 3. The discharging baffle 22 can be rotated up and down in the first chassis 3; when it is necessary to take out the construction waste fragments with larger particles, the discharging baffle 22 is rotated downward. Since the screening drum 4 is arranged at an angle, the construction waste fragments with larger particles will slide out of the screening drum 4 from the discharging port 21 under the drive of gravity.

As shown in Figure 4, a drum screen 15 is arranged inside the screening drum 4, and the drum screen 15 is covered with through holes for screening crushed materials. After the construction waste crushed materials enter the screening drum 4, when the screening drum 4 rotates, under the action of the drum screen 15, the crushed materials with a higher degree of crushing will be screened out by the drum screen 15.

A discharge pipe 6 is connected below the screening drum 4, and an inlet at one end of the discharge pipe 6 is arranged inside the screening drum 4.

As shown in FIG5 , a screening net 9 is arranged in the second chassis 7, the mesh number of the drum screen 15 is smaller than the mesh number of the screening net 9, and the screening net 9 can screen the crushed material again; a second drive motor 18 is installed on the stand 1, and the second drive motor 18 is arranged on one side of the second chassis 7. A swing mechanism 8 is installed at the bottom of the second chassis 7, and the swing mechanism 8 includes a transmission rod 801, and the transmission rod 801 is connected to the output shaft of the second drive motor 18. The second drive motor 18 can drive the transmission rod 801 to rotate, and both ends of the transmission rod 801 are rotatably installed on the stand 1, and the stand 1 is provided with a shaft that cooperates with the rotation of the transmission rod 801 Bearing, thereby enhancing the stability of the transmission rod 801; as shown in Figure 6, a connecting piece 802 is installed on the transmission rod 801, one end of the connecting piece 802 is a circular ring portion, and the circular ring portion is slidably mounted on the transmission rod 801, and the other end of the connecting piece 802 is a hinged bracket. A cross bar is provided at the bottom of the second chassis 7, and a protrusion is provided on the cross bar. The hinged bracket of the connecting piece 802 is hinged to the protrusion. When the transmission rod 801 rotates, the transmission rod 801, with the cooperation of the connecting piece 802, makes the second chassis 7 do a linear reciprocating motion, and the screening net 9 further finely screens the crushed materials when it is shaken down, so that the crushed materials with smaller particles fall from the screening net 9.

Among them, slide plates 19 are provided on both sides of the second chassis 7, one end of the slide plate 19 is connected to the side of the second chassis 7, one end of the slide plate 19 is slidably installed in a sleeve 20, and the sleeve 20 is fixedly installed on the stand 1; by setting a sliding matching structure of the slide plate 19 and the sleeve 20, the linear reciprocating motion of the second chassis 7 can be fully matched, and the transmission rod 801 can bear the force, thereby improving the service life of the swing mechanism 8.

In addition, the second chassis 7 is arranged at an angle, and the vertical height of the receiving end 16 is higher than the discharging end 17; by arranging the discharging end 17 at a lower position, it is convenient for large-particle crushed materials screened by the screening net 9 to be transported out of the second chassis 7 through the discharging end 17, thereby improving the smoothness of the operation of the overall equipment.

A discharge hopper 10 is provided below the second chassis 7, and the discharge hopper 10 provides a conveying channel for the fine crushed materials screened by the screening net 9, and transports them out of the second chassis 7. The discharge hopper 10 is fixedly mounted on the stand 1; and the discharge hopper 10 is a funnel-shaped structure, with the upper end of the discharge hopper 10 being the end with a larger opening, and the lower end of the discharge hopper 10 being the end with a smaller opening; by arranging the end with a larger opening at the top, the crushed materials can be prevented from leaking out, thereby ensuring the rate at which the overall equipment outputs fine crushed slag.
