[0026] A plurality of mounting bases 114 are fixedly mounted on the inner wall of the second box body 110, and connecting blocks 115 are arranged inside the mounting bases 114, and spring bodies 116 are arranged on the outer walls of the connecting blocks 115, and one side of the spring bodies 116 is connected to the inner wall of the mounting bases 114, and a filter screen 117 is mounted on the side of the connecting blocks 115 close to each other, and a vibration device 118 is arranged at the bottom of the filter screen 117, and a discharge port 119 is mounted on one side of the second box body 110, and a valve is arranged inside the discharge port 119, and the connecting shaft 122 is driven to rotate by the third motor 121, so that the metal sheet 123 can hit the bottom of the filter screen 117 to generate vibration, thereby facilitating the screening of stones and materials, and at the same time, by setting the mounting base 114, the connecting blocks 115 and the spring body 116 structure, the vibration amplitude of the filter screen 117 can be increased, thereby further improving the screening efficiency and the work efficiency.

[0027] Furthermore, the vibration device 118 includes a third motor 121, and a connecting shaft 122 is fixedly installed on the output end of the third motor 121. A plurality of metal sheets 123 are fixedly installed on the upper portion of the connecting shaft 122, and the top of the metal sheet 123 is in contact with the bottom of the filter screen 117. In actual use, through the arrangement of the above-mentioned structure, the vibration amplitude of the filter screen 117 can be increased, thereby further improving the screening efficiency.

[0028] Furthermore, a rotating shaft is provided on one side of the interior of the feed port 111, and a baffle 124 is installed on the rotating shaft. A first return spring 125 is fixedly installed on the bottom of the baffle 124, and the other side of the first return spring 125 is fixedly connected to the inner wall of the feed port 111. In actual use, through the setting of the above structure, the weight of the material presses the baffle 124 down, and then the tension of the first return spring 125 resets the baffle 124 to fit the inside of the feed port 111, thereby preventing dust from entering the interior of the second box body 110 from the feed port 111 after feeding, and at the same time forming a sealed environment.

[0029] Furthermore, a guide slope 120 is fixedly installed on one side of the bottom of the inner wall of the second box body 110. In actual use, the arrangement of the above structure has a guiding effect on the material.

In actual use, through the arrangement of the above structure, when the stirring shaft 127 is working, the fixing rod 131 drives the sleeve 132 to rotate, so that the second return spring 133 is in a compressed state, and then the insert rod 134 can be used to make the scraper 135 always squeeze the inner wall of the first box body 100 to fit, thereby having a better effect on cleaning the attachments on the inner wall of the first box body 100.

[0032] Working principle: When in use, the third motor 121 drives the connecting shaft 122 to rotate, so that the metal sheet 123 can hit the bottom of the filter screen 117 to generate vibration, which is convenient for screening stones and materials. At the same time, by installing the substrate 114, the connecting block 115 and the spring body 116 structure, the vibration amplitude of the filter screen 117 can be increased, and the screening efficiency is further improved, and the work efficiency is improved. The weight of the material presses the baffle 124 down, and then the baffle 124 is reset to fit the inside of the feed port 111 through the tension of the first return spring 125 to prevent dust from entering the second box body 110 from the feed port 111 after feeding, and a sealed environment can be formed at the same time. Through the setting of the above structure, when the stirring shaft 127 is working, the fixed rod 131 drives the sleeve 132 to rotate, so that the second return spring 133 is in a compressed state, and then the scraper 135 can always squeeze the inner wall of the first box body 100 through the insertion rod 134, so as to better clean the attachments on the inner wall of the first box body 100.
