A screening net 230 is movably installed, and a plurality of screening holes 231 are provided on the screening net 230. A placement block 240 is installed at the bottom of the screening net 230. A placement cavity 241 is provided in the placement block 240. A driving motor 242 for driving the screening net 230 is provided in the placement cavity 241. A storage bin 500 is installed outside the screening bin 200, and a scraping assembly 600 for scraping waste remaining on the screening net 230 is provided in the storage bin 500.

[0023] The scraping assembly 600 includes a through groove 610 opened in the storage bin 500, the through groove 610 corresponds to the movable groove 220, the inner wall of the storage bin 500 is opened with a cavity 620, a driving gear 630 is arranged in the cavity 620, a first reciprocating rod 640 is installed on the driving gear 630, a second reciprocating rod 650 is installed at the bottom of the driving gear 630, and scraping plates 641 for scraping waste remaining on the screening net 230 are installed at the ends of the first reciprocating rod 640 and the second reciprocating rod 650.

[0024] A sliding groove 680 is provided in the storage bin 500, and the sliding groove 680 is communicated with the cavity 620, and the scraper plate 641 is movably inserted in the sliding groove 680. A reciprocating rack 642 corresponding to the driving gear 630 is installed at the bottom of the first reciprocating rod 640 and the top of the second reciprocating rod 650, and the reciprocating rack 642 is meshed with the driving gear 630. A through hole 660 is provided in the storage bin 500, and a control crank 670 is inserted in the through hole 660.

[0025] The operator adds the raw material into the screening bin 200 through the upper hopper 100. The upper hopper 100 is designed to be inserted into the screening bin 200, so that the raw material can be accurately guided to the screening area to avoid overflow or misalignment of the raw material. In the screening bin 200, the raw material enters the feed port 210, and the feed port 210 is installed with a movable groove 220 and a screening net 230. The function of the movable groove 220 is to ensure that the raw material can be evenly distributed on the screening net 230, and the screening net 230 has a plurality of screening holes 231. According to the particle size of the raw material, some particles will pass through the screening holes 231, while larger particles will be blocked on the screening net 230.

[0026] A placement block 240 is installed at the bottom of the screening net 230, and a drive motor 242 for driving the screening net 230 is arranged in the placement block 240.

The vibration or rotation action helps to better separate the particles and improve the screening efficiency. Some of the waste materials remaining on the screening net 230 will be removed by the scraping assembly 600. The scraping assembly 600 includes components such as a driving gear 630, a reciprocating rod, and a scraping plate 641. These components scrape off the waste materials remaining on the screening net 230 with the help of reciprocating motion or a sliding groove 680, ensuring that the screening net 230 is always kept clean and improving the screening efficiency.

[0027] A control crank 670 is installed in the storage bin 500, through which the operator can conveniently control the movement of the scraper plate 641. The reciprocating movement of the scraper plate 641 is driven by the driving gear 630 and the reciprocating rod, and the operator can adjust the movement speed and frequency of the scraper plate 641 as needed to meet the screening requirements of different raw materials.

[0028] In this embodiment: by pre-screening the raw materials, large particles can be prevented from directly entering the mixing equipment, thereby effectively reducing the risk of equipment damage and blockage. The equipment uses vibration or rotation, combined with the screening mesh 230 and the screening holes 231, to more effectively separate particles and improve screening efficiency. The scraper assembly 600 can remove waste remaining on the screening mesh 230 and keep the screening mesh 230 clean, thereby ensuring the screening effect and stable operation of the equipment. By setting the control crank 670, the operator can easily control the movement of the scraper plate 641, adjust the screening effect as needed, and improve the flexibility and convenience of operation.

A first sealing strip 512 is installed on the first bin body 510. A second sealing strip 522 is installed on the second bin body 520. The first sealing strip 512 is attached to the second sealing strip 522, which can effectively improve the sealing performance of the storage bin 500. This can prevent waste from splashing out during the removal process, keep the working environment clean, and prevent external impurities from entering the screening area to affect the screening effect. At the same time, a clamping block 521 is installed on the second bin body 520, which can be easily engaged with the clamping slot 511 in the first bin body 510, making the assembly and disassembly of the storage bin 500 more convenient. In this way, the operator can more easily maintain and clean the equipment, thereby improving the maintainability and operating efficiency of the equipment.

[0031] In this embodiment: by adopting the first bin body 510 and the second bin body 520 structure, and providing a sealing strip and a card slot 511 between them, the sealing performance of the storage bin 500 is effectively improved. This helps to prevent waste from splashing out during the removal process, keep the working environment clean, and prevent external impurities from affecting the screening effect. At the same time, the design of the card block 521 on the second bin body 520 makes assembly and disassembly more convenient, and the operator can easily engage with the card slot 511 in the first bin body 510. Such a design improves the maintenance and cleaning efficiency of the equipment, and enhances the maintainability and ease of operation of the equipment.
