Technical Field
[0001] The utility model relates to the technical field of garbage disposal, in particular to a multi-stage screening device for large garbage. Background Art
[0002] "Oversized waste" generally refers to discarded items that are too large to fit directly into regular trash cans. This type of waste typically includes old furniture (such as sofas and mattresses), large appliances (such as refrigerators and washing machines), and renovation waste. Due to the special nature of these items, they cannot be handled like regular household waste and require specialized recycling or disposal methods.
[0003] Traditional large-scale garbage screening devices can quickly screen large-scale garbage, thereby accelerating its subsequent processing. However, this traditional device still has some limitations. For example, since large-scale garbage is often heavy, it makes it difficult to quickly remove the screened large-scale garbage from the inside of the screening device. In addition, during the screening process, large-scale garbage may collide with each other and produce smaller fragments. These fragments are difficult to collect effectively, thereby reducing the overall recycling efficiency.
[0004] Therefore, we are in urgent need of a large-scale multi-stage screening device that can quickly clean up garbage. Utility Model Content

DETAILED DESCRIPTION
[0020] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.
[0021] Example: A multi-stage screening device for large garbage, such as Figure 1-Figure 3 As shown, it includes a screening box 1, a strip screening plate 2, a baffle 21, a circular hole screening plate 3, a storage box 4, a connecting plate 5, an electric push rod 6, a cylinder 7 and an inclined plate 8. The strip screening plate 2 and the circular hole screening plate 3 are connected in an up-and-down sliding manner inside the screening box 1. The screening box 1 is connected to the storage box 4 in a left-and-right sliding manner inside. The area of the strip grooves on the strip screening plate 2 is larger than the circular grooves on the circular hole screening plate 3. The left part of the screening box 1 is rotatably connected to two baffles 21 through a rotating shaft. The circular hole screening plate 3 is not located below the strip screening plate 2. The storage box 4 is located below the circular hole screening plate 3. The strip screening plates 2, the circular hole screening plates 3 and the storage box 4 are arranged in this way to facilitate screening of garbage. The interior is connected with a connecting plate 5 in an up and down sliding manner, and the connecting plate 5 is connected to the strip screen plate 2 and the round hole screen plate 3. The front side of the screening box 1 is installed with an electric push rod 6 by bolts, and the telescopic end of the electric push rod 6 is connected to the connecting plate 5. The lower part of the strip screen plate 2 is installed with a cylinder 7 by bolts. The strip screen plate 2 is hinged with an inclined plate 8, and the inclined plate 8 is connected to the telescopic end of the cylinder 7. When the cylinder 7 is started, the telescopic end of the cylinder 7 will push the inclined plate 8 upward, so that the inclined plate 8 forms a slope with the right higher and the left lower on the strip screen plate 2, so that the garbage on the inclined plate 8 slides down along the slope, speeding up the cleaning speed of the garbage from the screening device, saving the time of manual cleaning, and improving work efficiency.
[0022] like Figure 1-Figure 5 As shown, it also includes a cover plate 9, a bidirectional screw rod 10, a motor 11, a placement frame 12, a magnet 13, a fixing rod 14, a fixing plate 15, an elastic member 16, and a limit plate 17. The front side of the screening box 1 is rotatably connected to the bidirectional screw rod 10, and the left and right sides of the bidirectional screw rod 10 are respectively threadedly connected to the cover plate 9. The shielding effect of the cover plate 9 can prevent the garbage on the inclined plate 8 from being scattered to the outside of the device due to vibration; the front side of the screening box 1 is installed with a motor 11 by bolts, and the output shaft of the motor 11 is connected to the bidirectional screw rod 10; the front and back sides of the screening box 1 are connected There are two placement frames 12, and magnets 13 are slidably connected inside the placement frames 12. Small metal particles in the garbage and metal fragments generated by collisions will be sucked away by the magnets 13, thereby realizing the classification of some metal garbage; the left part of the screening box 1 is connected to a fixing rod 14, and a fixing plate 15 is slidably connected between the fixing rod 14 and the screening box 1, and an elastic member 16 is connected between the fixing plate 15 and the fixing rod 14 through a spring seat; two limit plates 17 are connected to the left side of the screening box 1, and the limit plates 17 are respectively located below the strip screening plate 2 and the circular hole screening plate 3.
[0023] When the device is to be used to screen large garbage, the motor 11 is first started. The output shaft of the motor 11 drives the bidirectional threaded rod to rotate. When the bidirectional threaded rod rotates, it pushes the cover plate 9 to move to the left and right sides respectively, thereby revealing the inclined plate 8 inside the screening box 1. Then, the large garbage to be screened is poured onto the inclined plate 8. After the dumping is completed, the motor 11 is started again to reset the cover plate 9. Subsequently, the electric push rod 6 is driven to move the connecting plate 5 up and down. At the same time, the connecting plate 5 will also drive the strip screening plate 2 and the round hole screening plate 3 to move up and down together, so that the inclined plate 8 can be opened. The garbage on the inclined plate 8 vibrates up and down. Due to the shielding effect of the cover plate 9, the garbage on the inclined plate 8 can be prevented from being scattered outside the device due to vibration. At the same time, the collision between the garbage and the cover plate 9 helps to improve the vibration effect. In this process, the small metal particles in the garbage and the metal fragments generated by the collision will be sucked away by the magnet 13, thereby realizing the classification of some metal garbage. The medium-sized garbage will fall onto the circular hole sieve plate 3 through the strip grooves on the strip sieve plate 2, while the larger garbage will remain on the inclined plate 8. The medium-sized garbage falling on the circular hole sieve plate 3 will vibrate with the circular hole sieve plate 3, and the smaller ones will be sucked away by the magnet 13. The garbage will fall into the storage box 4 below through the circular groove on the circular hole screening plate 3, thus completing multi-stage screening; after the screening is completed, the electric push rod 6 is closed, the fixed plate 15 is moved forward and the elastic member 16 is compressed to release the fixation of the baffle 21, and then the baffle 21 is rotated to the left so that it is placed on the limit plate 17 to play a supporting role, which is convenient for subsequent garbage cleaning; the cylinder 7 is started, and the telescopic end of the cylinder 7 will push the inclined plate 8 upward, so that the inclined plate 8 forms a slope with a higher right and a lower left on the strip screening plate 2, so that the garbage on the inclined plate 8 slides down along the slope, accelerating the garbage from The cleaning speed in the screening device saves the time of manual cleaning and improves work efficiency. Because the garbage on the circular hole screening plate 3 is medium-sized garbage, it can be directly cleaned out manually. When the garbage in the storage box 4 is almost full, move the storage box 4 to the right to clean the garbage inside. At the same time, take the magnet 13 out of the placement frame 12, clean the metal garbage attached to its surface, and then put the magnet 13 back into the placement frame 12. Finally, reset the baffle 21 to prepare for the next screening work. Repeat the above steps for subsequent work. After completing the work, turn off the device.
