A feeding part connected to the inside of the drying cylinder 1 is arranged on the circumferential outer wall of the drying cylinder 1, and a shell 2 is sleeved on the drying cylinder 1. The drying cylinder 1 and the shell 2 rotate relative to each other, and the shell 2 and the feeding part correspond to each other.

[0028] A feed trough is provided on the circumferential inner wall of the housing 2, the feed trough is connected to the feed part, and a feed port 12 connected to the feed trough is provided on the housing 2, and the material can enter the feed trough from the feed port 12;

[0029] The feeding part includes a plurality of leakage holes 3, which are evenly arranged on the circumferential outer wall of the drying cylinder 1. One end of the leakage hole 3 is connected to the interior of the drying cylinder 1, and the other end is connected to the feeding groove.

[0030] like Figure 2 and Figure 3 As shown, the feeding part also includes a plurality of receiving plates 4, and the plurality of receiving plates 4 correspond to the plurality of leakage holes 3 one by one. The receiving plates 4 include a first connecting section and a second connecting section that are fixedly connected, and a first preset angle is formed between the first connecting section and the second connecting section. The first preset angle is an obtuse angle, and its opening direction is toward the rotation direction of the drying cylinder 1. The end of the first connecting section away from the second connecting section extends into the leakage hole 3 and is fixedly connected to the hole wall of the leakage hole 3. Optionally, the end of the first connecting section away from the second connecting section is fixedly connected to one-half of the hole wall of the leakage hole 3, thereby, the material can enter the feeding trough from the feeding port 12, and then enter the leakage hole 3 through the guidance of the receiving plate 4, and enter the interior of the drying cylinder 1.

[0031] The scraping part is arranged on the circumferential outer wall of the drying cylinder 1 and is arranged corresponding to the feeding part;

[0032] Specifically, the scraping part includes two adding rings 6, both of which are fixedly sleeved on the circumferential outer wall of the drying cylinder 1 and are respectively located on both sides of the leakage hole 3, and the adjacent side walls of the two adding rings 6 are respectively fixedly connected to both sides of the receiving plate 4;

[0033] The scraper part also includes a scraper 5, which is arranged at one end of the second connecting section away from the first connecting section. The scraper 5 is arranged on the side wall of the second connecting section facing the rotation direction of the drying cylinder 1 by bolts. One end of the scraper 5 away from the receiving plate 4 slides against the circumferential inner wall of the feeding trough, and one end of the scraper 5 away from the receiving plate 4 is provided with a first scraping portion, which is an acute-angle structure. The opening direction of the acute angle is away from the rotation direction of the drying cylinder 1. Therefore, during the rotation of the drying cylinder 1, the receiving plate 4 and the scraper 5 can be driven to rotate together. The scraping portion can shovel off the material on the circumferential inner wall of the feeding trough, and the material can fall along the scraper 5 to the receiving plate 4, thereby entering the interior of the drying cylinder 1;

[0034] It should be noted that countersunk holes are provided on the side wall of the scraper 5 facing the rotation direction of the drying cylinder 1 corresponding to the bolts.

[0035] Furthermore, if Figure 2 and Figure 3 As shown, a plurality of teeth 7 are evenly arranged circumferentially on the circumferential outer edge of the adding ring 6 away from the drying cylinder 1, and the plurality of teeth 7 and the plurality of scrapers 5 are arranged in a one-to-one correspondence. The teeth 7 of the two adding rings 6 are respectively located on both sides of the scraper 5, and the end of the teeth 7 away from the drying cylinder 1 and the end of the scraper 5 away from the receiving plate 4 are arranged flush, and the side wall of the teeth 7 facing the rotation direction of the drying cylinder 1 is the first side wall, and the first side wall is parallel to the radial direction of the drying cylinder 1, so as to facilitate the scraped material to enter the receiving plate 4.

[0036] like Figure 4 As shown, the scraping part also includes two groups of pick-up tooth assemblies, which are respectively arranged on the side walls away from the two adding rings 6, and the pick-up tooth assembly includes a plurality of external pick-up teeth 8, and the plurality of external pick-up teeth 8 correspond to the plurality of teeth 7 one by one, and the external pick-up teeth 8 have a third connecting section and a fourth connecting section, and the third connecting section and the side wall away from the scraper 5 are connected by bolts, and the side wall away from the external pick-up teeth 8 is provided with countersunk holes corresponding to the bolts;

[0037] A second preset angle is formed between the third connecting section and the fourth connecting section, the second preset angle is an obtuse angle, and its opening faces the side away from the tooth 7, and the fourth connecting section extends to the side of the tooth 7 facing the rotation direction of the drying cylinder 1, and a reinforcing plate is provided between the third connecting section and the fourth connecting section, and the reinforcing plate is located within the opening range of the second preset angle and is fixedly connected to the third connecting section and the fourth connecting section;

[0038] The scraper tooth assembly also includes a scraper 10. Specifically, the scraper 10 is connected to the side wall of the fourth connecting section close to the adding ring 6 by bolts. The side wall of the scraper 10 close to the adding ring 6 is provided with a countersunk hole corresponding to the bolt. The end of the scraper 10 away from the outer scraper tooth 8 is provided with a second scraping part, which is an acute angle structure, and its opening direction is away from the rotation direction of the drying cylinder 1. The second scraping parts of the two groups of scraper tooth assemblies are respectively slidably abutted against the two opposite inner walls of the feed trough, so as to shovel the material on the inner wall of the feed trough;

[0039] A plurality of feed ports 9 are evenly arranged on the circumferential outer edge of the adding ring 6 away from the drying cylinder 1. The feed ports 9 are located on the side of the teeth 7 facing the rotation direction of the drying cylinder 1, and correspond to the scraper 10. After the scraper 10 scrapes off the material on the inner wall of the feed trough, the material can fall from the feed port 9 onto the receiving plate 4 through the guiding effect of the scraper 10's own structure, and then enter the interior of the drying cylinder 1.

[0040] like Figure 1 As shown, the inner wall of the drying cylinder 1 is provided with a plurality of material receiving boxes 11, and the plurality of material receiving boxes 11 and the plurality of material leakage holes 3 are arranged one by one. The interior of the material receiving box 11 is hollow, and the material receiving box 11 has a first opening and a second opening connected to the interior thereof, the first opening is connected to the material leakage holes 3, and the second opening is connected to the interior of the drying cylinder 1, so that the scraped material enters the material receiving box 11 from the first opening through the material leakage holes 3, and enters the interior of the drying cylinder 1 from the second opening;

[0041] Furthermore, the material receiving box 11 has a third side wall and a fourth side wall, and a second preset angle is formed between the third side wall and the fourth side wall. The second preset angle is an obtuse angle, and its opening faces the leakage hole 3. The material entering from the leakage hole 3 falls on the third side wall through the first opening and can be output from the second opening through the guidance of the third side wall and the fourth side wall.

[0042] Working principle: The drying cylinder 1 is rotated by providing power through an external power component, and the drying cylinder 1 and the outer shell 2 form relative rotation. Materials are added from the feeding port 12, and the materials can enter the feeding trough from the feeding port 12, and then fall on the receiving plate 4, and slide down along the receiving plate 4 to the leakage hole 3, enter the receiving box 11 through the first opening, and output to the inside of the drying cylinder 1 from the second opening; the rotation of the drying cylinder 1 drives the adding ring 6, the receiving plate 4, the scraper 5, the outer scraping teeth 8 and the scraper 10 to rotate together, and the acute angle structure of the first scraping part of the scraper 5 slides against the circumferential inner wall of the feeding trough, which can remove the materials adhering to the circumferential inner wall of the feeding trough. Scraping is performed, and the scraped material is blocked by the teeth 7 and can fall onto the scraper 5, then enter the leakage hole 3 through the receiving plate 4, and finally enter the interior of the drying cylinder 1. The second scraping part of the scraper 10 can scrape the material on the two opposite inner walls of the feed trough, and the scraped material falls on the receiving plate 4 through the feed port 9, and finally enters the interior of the drying cylinder 1. Therefore, through the cooperation of the scraper 5 and the teeth 7, as well as the cooperation of the scraper 10 and the feed port 9, the material on the inner wall of the feed trough can be scraped off, so that the material can completely enter the interior of the drying cylinder 1, avoiding the waste caused by the material sticking to the outer shell 2, and improving the service life of the drying cylinder 1.

[0043] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
