Both the inner side wall and the outer side wall of the sliding frame 34 are coated with grease, so that the sliding frame 34 slides more smoothly, and friction between the cam 33 and the sliding frame 34 is reduced.
In the invention, the upper conveying belt 102 conveys materials in a cold storage bin into the feed hopper 3, the materials enter the feed cylinder 2 through the feed hopper 3, the materials enter the feed cylinder 2 and are respectively contacted with different blocking sheets 6, the blocking sheets 6 drive the rotating shaft 5 to rotate through the impact contact with the blocking sheets 6, and finally the materials are contacted with the two baffles 7 through the contact with the blocking sheets 6 for a plurality of times, so that the falling speed of the materials is greatly reduced, the materials slowly fall on the lower conveying belt 101 and are continuously conveyed forwards.
In the rotating process of the rotating shaft 5, the conducting rod 28 is driven to rotate through the insulating rod 27, the conducting rod 28 rotates to cut the magnetic induction line of the permanent magnet 26 to generate induction current, and the blocking sheets 6 positioned on different sides of the feeding barrel 2 can rotate in different directions when being impacted by materials, so that the conducting rods 28 on two sides generate induction current in different directions.
One of them pivot 5 still can drive the driving gear 37 rotation in the rotation process, through the meshing of driving gear 37 and driven gear 32, drive the dwang 31 rotation, the rotation of dwang 31 then can drive cam 33 rotation, cam 33 is in the rotation process, through the contact with the interior roof of sliding frame 34 and interior diapire, drive sliding frame 34 reciprocating motion from top to bottom, when sliding frame 34 upwards moves and presses first switch 35, then can make the conducting ring 29 and the electro-magnet 21 of feed cylinder 2 one side, and when sliding frame 34 downwards moves and presses second switch 36, then can make the conducting ring 29 and the electro-magnet 21 of feed cylinder 2 opposite side, and because the induced current of feed cylinder 2 both sides conducting rod 28 production different directions, the up-and-down reciprocating motion of sliding frame 34 can make electro-magnet 21 periodic production different orientation magnetic force.
When the electromagnet 21 is electrified to generate magnetic repulsion force on the magnetic block 12, the magnetic repulsion force enables the magnetic block 12 to drive the pump plate 11 to move downwards, at the moment, the pump plate 11 sucks air through the second pipe 15, the second pipe 15 sucks air from the upper part of the pump plate 11 through the transfer block 16, the third pipe 17 and the absorption holes 19, the air and dust sucked below the pump plate 11 are pumped into the cloth bag 24 through the fifth pipe 22 when the pump plate 11 moves downwards, the air is discharged through the cloth bag 24, the dust in the air is filtered, and when the electromagnet 21 is electrified to generate magnetic attraction force on the magnetic block 12, at the moment, the magnetic attraction force enables the magnetic block 12 to drive the pump plate 11 to move upwards, at the moment, dust is sucked through the first pipe 14, and meanwhile, the air and the dust sucked above the pump plate 11 are pumped into the cloth bag 24 through the corresponding fifth pipe 22, and the dust generated by the falling of the material is absorbed and collected through the up-and-down reciprocating motion of the pump plate 11.
After the processing is completed, the cloth bag 24 is taken down, the dust stored in the inside is collected, and the cloth bag 24 is cleaned.
