Description

Technical Field

[0001] The utility model relates to the technical field of screening equipment, in particular to a raw material screening equipment. Background Art

[0002] Raw material screening is a crucial step in industrial production and processing. It not only affects product quality and production efficiency, but also directly impacts the smooth progress of subsequent processes. Traditional raw material screening equipment typically uses mechanical vibration or manual screening. However, with technological advancements and rising production demands, the requirements for raw material screening equipment are also becoming increasingly demanding. Modern screening equipment must feature high efficiency, high precision, low loss, and ease of operation and maintenance.

[0003] Traditional screening equipment, when used, can easily cling to the wet material in the mesh of the screen, resulting in poor screening performance or even inability to screen the material. Many current screening systems lack convenient cleaning devices or effective cleaning mechanisms, requiring significant time and labor to shut down and clean the screen once it becomes clogged. This not only reduces production efficiency but also increases costs and labor intensity. Utility Model Content

[0031] Specifically, two bracket plates 1 are provided, one of which is welded to a mounting plate 12 on its outer surface, and a drive motor 11 is mounted on the top surface of the mounting plate 12. The advantage is that when the raw material is put into the screen 8, the drive motor 11 is started to drive the transmission rod 10 to rotate, the transmission rod 10 drives the gear 1 9 to rotate, the gear 1 9 drives the large gear ring 7 to rotate, and the large gear ring 7 drives the multiple connecting plates 6 to rotate, so that the screen 8 can rotate, thus screening the raw material.

[0032] Specifically, the top of the bracket plate 1 is fixedly connected to the support block 21, and the outer surface of the connecting rod 22 is provided with a plurality of sleeves 23 at equal intervals. The outer surface of the sleeves 23 is fixedly connected to two sets of clamping blocks 24, and the outer surface of the connecting plate 6 is welded with multiple spiral pieces 13. The advantage is that when the multiple connecting plates 6 rotate with the large ring gear 7, the multiple spiral pieces 13 welded on their outer surfaces will rotate. In this way, the raw materials inside the screen 8 will gradually move from the direction of the feed port to the direction of the discharge port, and finally be discharged from the discharge port.
