[0040] Anti-loss component, the anti-loss component includes a support plate 20, a first electric push rod 21, a connecting plate 22, a second electric push rod 23, a support frame 24 and a rubber scraper 25;

[0041] There are two support plates 20, which are respectively connected to both sides of the feed bin 12.

[0047] The support 10 plays a supporting role, and the speed reducer 13 is used to control the rotation of the drum 11.

[0048] Working principle:

[0049] After raw materials are conveyed into the drum 11 through the feed bin 12, the second electric push rod 23 on the connecting plate 22 is started. The second electric push rod 23 drives the support frame 24 to move downward, driving the rubber scraper 25 to move downward. When the second electric push rod 23 is fully extended, the first electric push rod 21 on the support plate 20 is started. The first electric push rod 21 contracts, driving the second electric push rod 23 on the connecting plate 22 to move downward, driving the support frame 24 and the rubber scraper 25 to continue moving downward until they move to the bottom of the feed bin 12. The rubber scraper 25 scrapes off the raw materials accumulated on the inner wall of the feed bin 12;

[0050] Subsequently, operate in the reverse order according to the above steps, and the support frame 24 and the rubber scraper 25 move upward to the top of the feed bin 12;

[0051] Repeat the above operations to repeatedly scrape the inner wall of the feed bin 12.

[0052] This step can regularly clean the inner wall of the feed bin 12, reduce the later labor intensity, and reduce material loss.

[0053] Please refer to Figures 1-2 、 Figure 3 This embodiment, on the basis of the above embodiment, further includes:

[0054] An adjusting assembly, the adjusting assembly includes a bracket 30 and a servo motor 31;

[0060] The collar 32 is sleeved on the rotating shaft 34, and the output end of the servo motor 31 is fixed on one group of rotating shafts 34.

[0061] Working principle:

[0062] Slip the collar 32 onto the rotating shaft 34 and tighten the locking rod 33. After the rubber squeegee 25 finishes scraping the inner wall of the inner feed bin 12, start the servo motor 31 on the bracket 30 to drive the rotation of the rotating shaft 34, thereby driving the rotation of the collar 32, driving the rotation of the support plate 20 on the collar 32, and further driving the rotation of the first electric push rod 21, the connecting plate 22, and the second electric push rod 23 on one side of the servo motor 31, driving the rotation of the support frame 24 and the rubber squeegee 25, causing the rotating shaft 34, the collar 32, the support plate 20, the first electric push rod 21, the connecting plate 22, and the second electric push rod 23 on the other side to rotate accordingly. Finally, the support frame 24 and the rubber squeegee 25 rotate out of the feed bin 12.
