Description

Technical Field

[0001] The invention relates to the technical field of feed processing equipment, in particular to a quantitative feeding device for feed processing. Background Art

[0002] Feed is a general term for food for animals raised by all people. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives, etc. During feed processing, the feed needs to be poured into the lower hopper, so a quantitative feeding component is required.

[0003] The prior art discloses a quantitative feeding device for feed processing with publication number CN220866592U, which comprises a feed processing machine, wherein four corners of the lower end of the feed processing machine are fixedly connected with a supporting stabilizing frame, and a quantitative feeding mechanism is positioned on one side of the feed processing machine. The device described above is a quantitative feeding device for feed processing. The quantitative feeding mechanism is convenient for quantitatively discharging the feed poured into the lower hopper and for unblocking the feed in the inner cavity of the lower feeding connecting pipe. The quantitative pneumatic butterfly valve can be used to adjust the flow medium to quantitatively control the feed falling in the lower feeding hopper. The feed enters the lower feeding connecting pipe through the control of the quantitative pneumatic butterfly valve. After the control motor is started, the rotating connecting rod is controlled to drive the rotation of the unblocking pushing blade, and the feed entering the inner cavity of the lower feeding connecting pipe is unblocked and pushed to one end one by one, which can prevent the feed from being blocked in the inner cavity of the lower feeding connecting pipe. The feed is pushed one by one into the feed processing machine for subsequent addition. A sealing rubber ring is put on the outer wall of the connecting positioning thread, and then the inner wall of the positioning connecting clamp ring is threadedly connected to the connecting positioning thread, and one end of the lower feeding connecting pipe is positioned on the inner wall of the positioning feed hole to enhance stability.

[0004] The above-mentioned quantitative feeding device for feed processing can put a sealing rubber ring on the outer wall of the connecting positioning thread, and then connect the inner wall of the positioning connecting clamp ring with the connecting positioning thread through threads, and position one end of the discharge connecting pipe on the inner wall of the positioning feed hole, thereby enhancing stability. However, the above-mentioned quantitative feeding device simply uses a quantitative pneumatic butterfly valve to adjust the flow medium in controlling the feed. The butterfly valve takes time to close and open, and it is easy to accumulate on the surface. There is no scraping structure and it cannot be swept down, so the feed amount cannot be accurately controlled, and the practicality is poor. Therefore, it is very necessary to design a quantitative feeding device for feed processing with strong practicality. Summary of the invention

The extended rotating rod part 313 rotates by utilizing the centrifugal force generated by driving the stepping motor 304 to rotate, and follows the swing, and the bottom of the scraper 310 is in contact with the sealing baffle 309 to slide, which can ensure that all the feed is pushed down, and avoid the top of the sealing baffle 309 from being missed, resulting in inaccurate feed amount. The feed amount can be accurately controlled, and it is highly practical. The scraper 310 is set to be used in conjunction with the internal blowing discharge device 6, and the fan box can be started when in use The fan inside 602 discharges air through the guide tube 604 under the guidance of the hollow air guide member 603 and the guide tube 604, and the blowing direction conforms to the rotation direction of the scraper 310, which can make the rotation speed of the scraper 310 greater than the rotation of the baffle plate 309, avoiding the situation that the scraper 310 cannot slide on the top of the baffle plate 309 and cannot push all the feed down when the two rotate at the same speed. It can ensure that all the feed is pushed down and leaks out from the discharge box 409, so as to achieve the purpose of controlling the feeding. The feeding control device 3 and the internal air blowing discharge device 6 are used together to ensure the feeding accuracy, and then the magnetic baffle 407 can be opened before the discharge box 409 falls to ensure that the feed can fall into the control conveying bucket.
