[0002] Linear vibrating screen for mineral processing is a kind of equipment used for screening solid particles, which is widely used in mineral processing, coal, metallurgy, chemical industry, building materials and other industries. The linear vibrating screen generates vibration force through the vibration motor, which makes the screen body vibrate linearly, so that the material is screened on the screen surface. The linear vibrating screen uses the vibration motor excitation as the vibration power source to make the material be thrown up on the screen and move forward linearly at the same time. The material enters the feed port of the screening machine evenly from the feeder, and produces several specifications of screened materials and screened materials through the multi-layer screen, which are discharged from their respective outlets. It has low energy consumption, high output, simple structure, easy maintenance, fully enclosed structure, no dust spillage, automatic discharge, and is more suitable for assembly line operation. The linear vibrating screen needs to vibrate during operation.

The rotating shaft 24 passes through and is fixedly connected to the transmission roller 25. The ore materials to be screened are poured into the shell 3 through the feed hopper 5. First, the ore materials will fall onto the screen 26. The motor 22 is started. When the motor 22 is started, the output shaft will drive the rotating shaft 24 to rotate, so that the rotating shaft 24 drives the transmission roller 25 to rotate. The surface of the transmission roller 25 is transmission-connected with the screen 26. At the same time, the reciprocating cylinder 213 pushes back and forth. The screen 26 is subjected to a certain degree of vibration to prevent some mineral materials from being stuck on the screen 26, and the screening efficiency can also be improved. Larger mineral materials will be transported to the discharge port 6 by the screen 26 for discharge, while smaller mineral materials will be screened by the screen 26 and discharged from the discharge port 7; a chute 27, a chute 27 is opened on the inner side of the shell 3, the chute 27 is penetrated and slidably connected by a support rod 28, the support rod 28 is penetrated and rotatably connected with a rotating roller 29, the inner side of the chute 27 is slidably connected with a slide plate 210, the bottom of the slide plate 210 is in contact with the top of the support rod 28, and a clamping spring 211 is fixedly connected between the top surface of the slide plate 210 and the inner side of the chute 27.

When the connecting block 214 is pushed by the reciprocating cylinder 213, the rotating roller 215 that is in contact with the screen 26 will move upward and push the screen 26 to prop up. When the screen 26 is propped up, the screen will be 26 contacts the rotating roller 29, and the screen 26 pushes the rotating roller 29 to move upward, so that the rotating roller 29 drives the support rod 28 to move upward, preventing the reciprocating cylinder 213 from supporting the screen 26 through the connecting block 214 and the rotating roller 215, causing the screen 26 to be stretched and deformed. At the same time, the reciprocating push of the reciprocating cylinder 213 causes the screen 26 to vibrate to a certain extent, preventing some mineral materials from being stuck on the screen 26, and also improving the screening efficiency. Larger mineral materials will be transported to the discharge port 6 by the screen 26 for discharge, while smaller mineral materials will be screened by the screen 26 and discharged from the discharge port 27. Vibration screening is performed by vibrating the screen 26, and the screen 26 transmission allows the mineral materials to be better screened without damaging the shell 3, and only the screen 26 needs to be replaced, which is convenient and quick.
