step two: and (3) feeding of feed: as shown in fig. 1, 2 and 3, the granulated feed screened from the filter screen 14 falls into the feed hopper 20 and is conveyed from the bottom of the feeding column 3 to the inside of the feeding box 23 along with the rotation of the spiral vane shaft 19, when the feed is conveyed to the inside of the feeding box 23, the feeding disc 18 is synchronously driven to rotate by the rotation of the spiral vane shaft 19, the granulated feed in the feeding box 23 is driven to rotate by the rib 181 on the lower surface while the feeding disc 18 rotates, and the rotating feed granules are thrown out from the feeding port 231 by using centrifugal force, so that the feeding is realized, the time and labor are saved, and the working efficiency is high;

step three: discharging powder feed: referring to fig. 7 and 8, after the powder feed falls into the hopper 15, when the receiving mechanism 7 is not located under the blanking port 24, the first spring 64 pushes the discharging plate 62 to be located at the right position, so that the discharging port 63 on the discharging plate 62 is misaligned with the blanking port 24, that is, the blanking port 24 is not communicated, the discharging plate 62 blocks the blanking port 24, the blanking port 24 does not discharge, the downward force is applied to the pressing plate 94 at the right end of the discharging plate 62 through the connecting rod 66, so that the pressing plate 94 drives the second gear 95 to move down along the guiding rod 93 and engage with the gear post 92, the first gear 91 is driven to synchronously rotate by the rotation of the spiral vane shaft 19, the gear post 92 is driven to rotate through the first gear 91, the gear second 95 and the multi-edge rod 96 are driven to synchronously rotate by the rotation of the gear post 92, the worm 98 is driven to rotate through the multi-edge rod 96, the worm 98 drives the worm 97 to rotate, the conveyor 5 is driven to operate through the first, the conveyor belt 5 operates to enable the empty receiving mechanism 7 to approach the blanking port 24, as shown in fig. 4 and 5, along with the operation of the conveyor belt, when the upper end of the buckle rod 76 on the empty receiving mechanism 7 is abutted against the lug 65 and applies a leftward force to the discharging plate 62 through the lug 65, so that the discharging plate 62 moves leftward along the sliding sleeve 61, and the discharging port 63 is synchronously driven by the leftward movement of the discharging plate 62 to approach the blanking port 24 and gradually coincide and communicate with the blanking port;

when the blanking port 24 is communicated with the discharging port 63 in a facing manner, the left moving of the blanking plate 62 drives the pressing plate 94 and the second gear 95 to move upwards along the guide rod 93 through the connecting rod 66, and the second gear 95 is separated from the gear column 92, so that the second gear 95 does not rotate, after the second gear 95 stops rotating, the worm 98 and the turbine 97 synchronously stop rotating, the same first belt pulley group 8 and the same conveying belt 5 synchronously stop rotating, and at the moment, the material receiving box 71 is positioned right below the discharging port 63 for discharging;

discharging powder feed: after the conveyer belt 5 stops, the material receiving box 71 is positioned under the material dropping port 24, at this time, the material discharging port 63 is communicated with the material dropping port 24, the powder feed falls into the material receiving box 71 from the material collecting hopper 15 through the material dropping port 24 and the material discharging port 63, as shown in fig. 5 and 8, as the powder feed falls into the material receiving box 71, the gravity of the powder feed on the lifting plate 72 is gradually increased, so that the lifting plate 72 descends, and the second spring 73 is compressed to enable the second spring 73 to obtain a restoring force, when the lifting plate 73 descends to the horizontal section of the buckling rod 76, downward pressure is applied to the horizontal section, so that the buckling rod 76 moves downwards along the through groove 75 and compresses the third spring 74, and the third spring 74 obtains a restoring force;

transferring and collecting powder feed: the lifting plate 72 descends to drive the buckling rod 76 to descend synchronously along with the increase of the powder feed, after the buckling rod 76 is separated from the convex block 63, the convex block 63 is free from the action of force, the discharging plate 62 moves rightwards along the sliding sleeve 61 under the action of restoring force of the first spring 64, the discharging port 63 is staggered with the blanking through port 24, the discharging plate 62 blocks the blanking through port 24, discharging is stopped, downward pressure is applied to the pressing plate 94 through the connecting rod 66 simultaneously by the discharging plate 62, the second gear 95 is contacted with the gear column 92 again, the second gear 95 drives the worm 98 and the turbine 97 to rotate through the multi-edge rod 96, so that the conveying belt 5 is driven to run through the first pulley group 8 again, the conveying belt 5 runs and simultaneously transfers the full receiving mechanism 7 to the blanking of the powder concentration box 4, meanwhile, the empty receiving mechanism 7 is also shifted to be under the through port 24, the full receiving mechanism 7 transfers the direction on the conveying belt 5 and simultaneously pours the powder in the receiving box 71 into the powder collection box 4, meanwhile, under the action of restoring forces of the second spring 73 and the third spring 74, the lifting plate 72 and the buckling rod 76 are reset so as to be used for receiving materials next time, so that automatic material feeding, material receiving, blocking and material conveying are circularly carried out, the operation frequency of the conveying belt 5 is adaptively adjusted according to the powder quantity, namely more powder feed is generated, the operation frequency of the conveying belt 5 is high, less powder feed is generated, the operation frequency of the conveying belt 5 is low, the output energy consumption of the motor 22 is favorably reduced, and energy is saved.
