Description

Technical Field

[0001] This utility model belongs to the field of solid waste grading technology, specifically relating to an automated solid waste vibrating grading screen. Background Technology

[0002] Solid waste grading refers to the process of separating solid waste into different grades or categories, with the aim of better realizing the treatment, disposal, and resource recycling of solid waste. Grading by particle size is mainly carried out by vibrating screens. However, due to the complex composition of solid waste, when the material contains a lot of sticky substances, such as wet organic waste or construction waste with sticky soil, these sticky components are easy to adhere to the screen and clog the screen holes. When the material has a high moisture content, fine particles are easy to clump together, thus blocking the screen pores. At the same time, because the shape of solid waste is relatively irregular, it is also easy to get stuck in the screen pores. Screen clogging will cause a sharp drop in screening efficiency, preventing some fine particles that should pass through the screen from passing through normally, thus reducing the accuracy and efficiency of grading. Utility Model Content

[0003] This utility model provides an automated solid waste vibrating grading screen, which features an adjustable screen tilt angle via the extension and retraction of several lifting rods. This allows movable shaft one and movable shaft two to move at the top and bottom of the screen, respectively, separating stuck materials from the screen's pores. This helps prevent materials from clogging the screen's pores and reducing the accuracy and efficiency of grading.

[0004] This utility model provides the following technical solution: It includes a base, a vibration motor, and lifting rods. Several lifting rods are fixedly connected to the top of the base. A spring is provided at the top of each lifting rod, and a connecting seat is provided at the top of each spring. A screen is provided between several connecting seats.

[0021] This implementation includes a base 1, a vibrating motor 111, and lifting rods 12. Several lifting rods 12 are fixedly connected to the top of the base 1. The height of the top of each lifting rod 12 rises or falls as it moves. The lifting rods 12 are positioned in pairs. A spring 121 is located at the top of each lifting rod 12, and its bottom is fixedly connected to the lifting rod 12. A connecting seat 122 is located at the top of each spring 121, and its bottom is fixedly connected to the top of the spring 121. The height of the spring 121 and connecting seat 122 can be adjusted by extending or retracting the lifting rods 12. A screen 2 is located between the connecting seats 122. When the material is at the top of the screen 2, the vibration of the screen 2 can screen the material, allowing materials smaller than a certain size to be screened. Material within the mesh openings of screen 2 falls downwards through the openings, while material larger than the mesh openings falls to the sides of screen 2 through the guide. Side plates 21 are provided on both sides of screen 2, fixedly connected to screen 2, and positioned opposite each other. A connecting plate 23 is provided on the side of side plate 21 furthest from screen 2, parallel to the side plate 21. A vibrating motor 111 is fixedly connected to the connecting plate 23, causing screen 2 to vibrate, thus improving screening efficiency. A connecting seat 122 is slidably connected to the connecting plate 23. The tilt direction of screen 2 can be adjusted by raising and lowering several lifting rods 12. During the raising and lowering process, the sliding of the connecting seat 122 and the connecting plate 23... To avoid interference between the connecting seat 122 and the connecting plate 23, a movable shaft 3 is provided at the top of the screen 2. The movable shaft 3 rolls at the top of the screen 2, and its bottom is in contact with the top of the screen 2. When the tilt direction of the screen 2 changes, the movable shaft 3 rolls from high to low. Through the rolling of the movable shaft 3 at the top of the screen 2, materials stuck to the screen 2 and those that are stuck together can be pressed downwards, causing them to fall through the holes of the screen 2. Connecting frames 31 are provided at both ends of the movable shaft 3. The connecting frames 31 are fixedly connected to the movable shaft 3, and the two connecting frames 31 are slidably connected to the side plate 21. A movable shaft 4 is provided at the bottom of the screen 2. Movable blocks 41 are provided at both ends of the movable shaft 4. The movable blocks 41 are slidably connected to the side plate 21. The connection between the movable block 41 and the side plate 21 allows the movable shaft 4 to move at the bottom of the screen 2, with the top of the movable shaft 4 in contact with the bottom of the screen 2. When the movable shaft 4 moves at the bottom of the screen 2, it can push upwards the material that is larger than the screen 2's aperture and stuck on the screen 2, separating the stuck material from the screen 2's aperture. The connecting frame 31 and the movable block 41 are connected by a connecting belt 311. The positions of the movable shaft 4 and the movable shaft 3 are offset. When the movable shaft 3 moves, the movable shaft 4 can be moved through the connecting belt 311. The movable shaft 3 is heavier than the movable shaft 4. When the screen 2 is tilted, the movable shaft 3 will roll downwards, while the movable shaft 4 is lighter than the movable shaft 3.Therefore, movable shaft 3 drives movable shaft 4 to move from a lower position to a higher position, thereby clearing the material clogging the screen 2. The screen 2 allows for the grading of solid waste according to particle size. The tilt angle of the screen 2 can be adjusted by the extension and retraction of several lifting rods 12. When the tilt angle of the screen 2 changes, movable shafts 3 and 4 move at the top and bottom of the screen 2 respectively. The rolling of movable shaft 3 at the top of the screen 2 presses down any material adhering to the screen 2 or clumped together, causing it to fall through the screen 2's openings. Movable shaft 4 pushes upwards any material larger than the screen 2's openings that is stuck on the screen 2, separating the stuck material from the screen 2's openings. This helps prevent material from clogging the screen 2's openings and reducing the accuracy and efficiency of grading.

[0022] The base 1 has a support rod 11 on its top, and the vibration motor 111 is fixedly connected to the top of the support rod 11. The support rod 11 is perpendicular to the base 1, and the position of the vibration motor 111 can be fixed by the support rod 11.

[0023] A fixing block 22 is provided on the side of the side plate 21 away from the screen 2, and the connecting plate 23 is fixedly connected to the fixing block 22; the fixing block 22 is fixedly connected to the side plate 21, and the fixing block 22 is parallel to the side plate 21. Through the connection of the fixing block 22, there is a gap between the connecting plate 23 and the side plate 21, and the gap between the connecting plate 23 and the side plate 21 is greater than the thickness of the movable block 41.

[0024] Two connecting grooves 211 and two arc-shaped grooves 212 are provided on the side of the side plate 21 away from the screen 2. The arc-shaped grooves 212 are connected to the ends of the two connecting grooves 211, and the two connecting grooves 211 are located at the top and bottom of the fixing block 22, respectively. The two arc-shaped grooves 212 are located at both ends of the side plate 21, and the two connecting grooves 211 are parallel to each other.

[0025] The connecting frame 31 is slidably connected to the connecting groove 211 located above the fixed block 22, and the movable block 41 is slidably connected to the connecting groove 211 located below the fixed block 22. When the movable block 41 and the connecting frame 31 slide, the connecting frame 31 and the movable block 41 will not contact the fixed block 22, so the fixed block 22 will not interfere with the connecting frame 31 and the movable block 41.

[0026] The connecting belt 311 is slidably connected to the inner side of the connecting groove 211 and the arc groove 212; when the positions of the connecting frame 31 and the movable shaft 3 move, the connecting belt 311 will slide inside the connecting groove 211 and the arc groove 212, thereby causing the movable block 41 and the movable shaft 4 to move with the connecting belt 311.

[0027] A groove 231 is provided on the side of the connecting plate 23 away from the fixed block 22, and the connecting seat 122 is slidably connected to the groove 231. The groove 231 is parallel to the connecting plate 23, and the tilt angle of the screen 2 can be changed as the lifting rod 12 rises and falls by sliding the connecting seat 122 and the groove 231.

[0028] The working principle and usage process of this utility model are as follows: First, solid waste is poured onto the top of the screen 2. The vibrating motor 111 causes the screen 2 to vibrate, allowing the solid waste to be graded according to particle size. When the pores of the screen 2 become clogged, the tilt direction of the screen 2 can be adjusted by raising and lowering several lifting rods 12. Reversing the tilt direction causes the first movable shaft 3 to roll downwards. The second movable shaft 4, being lighter than the first movable shaft 3, is connected by the connecting belt 311, allowing the first movable shaft 3 to move the second movable shaft 4 from a lower position to a higher position. The rolling of the first movable shaft 3 on the top of the screen 2 presses down any material adhering to or clumped together on the screen 2, causing it to fall through the pores. When the second movable shaft 4 moves to the bottom of the screen 2, it pushes upwards any material larger than the pores that is stuck on the screen 2, separating the stuck material from the pores.
