[0033] Working principle: when the device is screening feed, the feed is added to the upper end of the screening machine body 21, and then the special connection between the support frame 28 and the screening machine body 21 (since the screening machine body 21 and the support frame 28 are not fixedly connected, and the support frame 28 is provided with a machine that can vibrate the screening machine body 21) can screen the feed. After a period of screening, the screening screen plate 22 will be blocked by the screened feed. At this time, the user removes the screened material below, and then the positioning mechanism and the jacking mechanism in the device cooperate to jack out the screening screen plate 22. The user pulls the two pull rods 14, so that the two pull rods 14 move towards the sides of the screening machine body 21. At this time, the two positioning blocks 15 will also move to the sides under the pulling of the two pull rods 14. The two positioning blocks 15 will move out of the clamping slot 23 opened in the screening screen plate 22. At this time, the screening screen plate 22 and the screening machine body 21 are in a state of being unlocked. Under the action of the second spring 27, the two sliding blocks 25 will be jacked up. At this time, under the action of the jacking of the two sliding blocks 25, the screening screen plate 22 will be moved upwards, and will stop when it reaches the top position of the sliding slot 26 opened in the screening machine body 21. At this time, the screening screen plate 22 will appear at the upper end of the screening machine body 21. Since the screening screen plate 22 is rotatably installed in the two sliding slots 26 opened in the screening machine body 21 through the rotating rod 24, the screening screen plate 22 can be flipped. At this time, the blocked side of the screening screen plate 22 will be flipped to the ground. Knock the screening screen plate 22 a few times, and the blocked part will be completely penetrated. After flipping, the screening screen plate 22 can be directly pressed towards the inside of the screening machine body 21. Through the first spring 12 in the two positioning mechanisms, the screening screen plate 22 can be quickly installed, so that it can continue to be used. The jacking mechanism can quickly jack out the screening screen plate 22 from the screening machine body 21 and flip it, greatly shortening the time required for cleaning and blocking. The device can quickly recover to normal screening work. The traditional cleaning method may need to disassemble the equipment parts to dredge, which will cause a long shutdown. The design of jacking the screen plate upwards and flipping it can quickly process the blocked part, which may save several hours compared with the traditional method, effectively improving the overall production efficiency. The positioning mechanism can quickly disassemble the screening screen plate 22 from the screening machine body 21. When the screening screen plate 22 is deformed or broken during the use of the feed screening machine, the damaged screening screen plate 22 can be quickly removed by the maintenance personnel, the fault point can be accurately positioned, and the problem can be timely discovered and repaired. Compared with the traditional equipment that is difficult to disassemble, the maintenance time is greatly shortened.
