[0037] See also Figure 2 and Figure 7 As shown, a scraping structure 6 is provided at both ends of the rotary drum machine 1. The scraping structure 6 includes a connecting plate 62 and two connecting rods 61. The two connecting rods 61 are respectively welded to the two ends of the connecting plate 62, and the ends of the two connecting plates 62 are respectively slidably connected with the inside of the rotating circle 1 52 and the rotating circle 2 53. A row of scrapers 63 are welded to the bottom end of the connecting plate 62. The material of the scraper 63 is soft metal material. The length of the scraper 63 is greater than the distance between two adjacent fixed shafts 54. The length of the scraper 63 is greater than the distance between the two fixed shafts 54, which can make foreign matter return to the scraper 63, and the scraper 63 contacts the inner wall of the rotary drum machine 1. The connecting rod 61 and the connecting plate 62 can move synchronously along the axial direction of the connecting rod 61, so that the scraper 63 on the lower surface of the connecting plate 62 moves, which can scrape the inner wall of the rotary drum machine 1.

When the rotating sleeve 1 56 and the rotating sleeve 2 58 move to the end position of the fixed shaft 54, the rotating sleeve 1 56 and the rotating sleeve 2 58 push the toggle rod 65 of the fixed plate 64 to move, so that the fixed plate 64 continues to move toward the end of the connecting rod 61, and the scraper 63 at the lower end of the connecting plate 62 moves synchronously, which can clean the foreign matter adhered to the bottom end of the rotary drum machine 1, and ensure that the foreign matter at the bottom is cleaned when the airflow blows it.

[0038] See also Figure 7 and Figure 8 As shown, both ends of the toggle rod 65 are in contact with the rotating sleeve 2 58, and the end of the telescopic spring 67 is connected to the fixed plate 64. The telescopic spring 67 is used to push the fixed plate 64 to move. When the rotating sleeve 1 56 and the rotating sleeve 2 58 move to the two ends of the rotary drum machine 1, the ends of the rotating sleeve 1 56 and the rotating sleeve 2 58 are in contact with the toggle rod 65. The toggle rod 65 can move along the axis of the connecting rod 61, and the telescopic spring 67 is used to push the fixed plate 64, so that the scraper 63 of the connecting plate 62 moves back and forth.

The scraper 63 is used to clean foreign matter adhering to the inner wall of the rotary drum machine 1. A stepper motor is installed at the driving wheel 8. The stepper motor is used to rotate the connecting plate 62 to the bottom. Every time the rotary drum machine 1 needs to stop rotating, the driving wheel 8 is driven by the stepper motor to rotate, so that the rotary drum machine 1 rotates to the specified position. At this time, the connecting plate 62 is located at the bottom of the rotary drum machine 1, and the scraper 63 of the connecting plate 62 contacts the inner wall of the rotary drum machine 1, so that the foreign matter accumulated on the inner wall of the rotary drum machine 1 can be cleaned.

[0040] It should be noted that when the rotary drum machine 1 stops rotating, the driving wheel 8 can be driven to rotate by the stepper motor, so that the connecting plate 62 of the rotary drum machine 1 is located at the bottom, and the rotating sleeve 1 56 and the rotating sleeve 2 58 move to the end position of the fixed shaft 54. The foreign matter cleaned by the cleaning structure 5 will accumulate at the bottom of the rotary drum machine 1. The driving wheel 8 is driven by the stepper motor to rotate slightly repeatedly, so that the rotary drum machine 1 and the fixed end 2 move slightly. At this time, the rotating sleeve 2 58 moves the toggle rod 65 of the fixed plate 64, so that the connecting plate 62 moves along the axis of the connecting rod 61, and the telescopic spring 67 pushes the fixed plate 64.

The cylindrical surface of the connecting rod 61 is provided with a limiting groove 73, and the interior of the limiting groove 73 is slidably connected to the end of the limiting column 72, and the fixed plate 64 continues to move so that the limiting column 72 and the limiting groove 73 are in contact. 3, so that the connecting rod 61 is deflected. Since the scraper 63 is a soft metal, the scraper 63 can be deformed; the shape of the limiting groove 73 is a wavy line segment and a straight line segment, the wavy line segment of the limiting groove 73 slides with the limiting column 72, the cam 71 and the toggle rod 65 swing back and forth, and the end face of the toggle rod 65 is slidably connected with the end face of the rotating sleeve 58, the limiting column 72 of the fixed plate 64 is moved along the inside of the limiting groove 73, the cam 71 swings and knocks on the inner wall of the rotary drum machine 1, so that the adhered foreign matter is separated from the inside of the rotary drum machine 1, and the foreign matter can be discharged under the blowing of the blower 9.
