The use of the top cover box and the buffer frame can effectively block these particles, making the working area cleaner and tidier, and reducing pollution to the environment. 3. Improve work efficiency: Reduce the downtime caused by cleaning the splashed sand and gravel, so that the vibration screening machine can continue to operate, thereby improving the vibration screening efficiency and output. 4. Protect equipment: The setting of the top cover box and buffer frame also helps to protect the vibrating screen itself and other related equipment from being worn or damaged by hard particles, extending the service life of the equipment. 5. Improve product quality: Through effective splash control, it is possible to avoid the mixing of the screened sand and gravel with the splashed impurities, thus ensuring the purity and quality of the product. In summary, this setting not only enhances the safety and environmental protection of the operation, but also improves the working efficiency and product quality of the vibrating screen, reduces the wear on the equipment, and is a very practical and efficient design improvement;

[0030] 2. The utility model inserts the bottom cover into the bottom trough of the vibrating screen machine, and the staff inserts the force rod into the inner side of the drum, and then the staff rotates the drum. At this time, the drum drives the semicircular sweeper to rotate, and the semicircular sweeper continuously sweeps the bottom end of the vibrating working area, so as to prevent excessive sand and gravel from blocking the bottom end of the vibrating working area, and will produce the following effects: 1. Maintain the patency of the vibrating working area: the semicircular sweeper continuously sweeps the bottom end of the vibrating working area, effectively preventing sand and gravel and other materials from accumulating in this area. In this way, sand and gravel will not block the bottom end too much, ensuring the screening efficiency and continuous operation of the vibrating screen machine. 2. Improve sorting efficiency: Keeping the bottom end of the vibrating working area unblocked helps to better separate sand and gravel from other materials, and improves the screening accuracy and efficiency. 3. Reduce equipment maintenance and failure: Preventing the blockage of materials at the bottom of the working area can reduce equipment wear and downtime, reduce maintenance costs and improve equipment reliability. 4. Increase production: By effectively removing blockages, the vibrating screen machine can continue to operate uninterruptedly, further improving overall production. 5. Protect the safety of workers: Reduce potential equipment failures and accidents caused by material blockage, and provide a safer working environment for workers. Overall, the use of the bottom cover and the semicircular sweeper not only improves the working efficiency and performance of the vibrating screen, but also reduces the technical and safety problems that may be encountered during operation, and enhances the stability and reliability of the entire screening process.
