[0038] The structure and use principle of the screening device body 1 and the limiting mechanism 6 in the utility model have been disclosed in a screening device for the production and processing of magnesium-silicon-iron alloy disclosed in Chinese patent application No. 202020222729.4, and its working principle is that when the user needs to disassemble the feed bin 4, the fixed rod is moved, and the fixed rod drives the second fixed plate to move, and the second fixed plate slides inside the first fixed frame, and at the same time squeezes the spring to contract, and the second fixed plate drives the clamping rod to move, so that the clamping rod is separated from the inside of the first fixed plate, and when the clamping rod is separated from the inside of the first fixed plate, the feed bin 4 is moved upward.

[0039] Working principle and use process of the utility model: When the utility model is used, the magnesium-silicon-iron alloy is added into the screening device body 1 through the feed bin 4, and then the magnesium-silicon-iron alloy is screened through the screening device body 1. During screening, the dust flying out of the feed bin 4 is collected and processed by the dust collection component 5. When the feed bin 4 needs to be replaced, the limit of the fixed frame 3 is released by the limit mechanism 6, and then the fixed component 7 fixes the limit mechanism 6 to prevent the limit mechanism 6 from returning to its original position, and then the feed bin 4 is taken out. The new feed bin 4 is installed, and the fixing of the limit mechanism 6 is released by the fixing assembly 7, and the limit mechanism 6 returns to its original position to fix the feed bin 4. When the dust collection assembly 5 is in use, the exhaust fan 52 is started, and the dust flying out of the feed bin 4 during screening is sucked into the dust collection box 51 through the conveying pipe 54 and the dust collecting cover 55. When the collected dust needs to be processed, the limit plug 58 is pulled up, and then the sealing plug cover 57 is removed, and then the disassembly box 56 can be taken out. To process the dust, press the pressing rod 532, and press The pressure rod 532 compresses the return spring 534, so that the cleaning brush plate 533 moves to clean the filter screen 53, so that when the device is in use, it can collect and process the dust flying out of the feed bin 4 during screening, and it is convenient to process the collected dust, which improves the practicality of use. When the fixing assembly 7 is in use, the fixing rod of the limit mechanism 6 moves to one side to drive the support plate 71 to move. The support plate 71 moves, and under the action of the guide slide, it drives the clamping block 72 to move up, and the clamping block 72 The upward movement drives the extrusion rod 73 to move upward and compress the clamping spring 75 until the support plate 71 moves to the clamping hole and the clamping block 72 overlaps. The clamping block 72 is inserted into the clamping hole to fix the support plate 71, thereby fixing the fixing rod of the limiting mechanism 6 to prevent it from rebounding. When the device is in use, it is convenient for the limiting mechanism 6 to release the limit on the fixing frame 23, and then to limit and fix the fixing rod of the limiting mechanism 6 to prevent the limiting mechanism 6 from returning to its original position, thereby further facilitating the disassembly and assembly of the feed bin 4 and improving the practicality of use.
