[0020] like Figures 1 to 4 As shown, the utility model is a raw material pretreatment device, comprising: a feeding box 1, a feeding pipe 2, a raw material pretreatment box 3, and a screen drum 10 for screening the raw materials.

[0021] One end of the sieve drum 10 is in an open structure, and the diameter of the open opening is larger than the diameter of the feeding pipe 2 , so that the raw materials can fall from the feeding pipe 2 into the sieve drum 10 .

[0022] The rotatable scraper 11 is installed in the screen drum 10, and the spiral blade 7 is installed in the feeding pipe 2. The scraper 11 is coaxially connected to the spiral blade 7. The spiral blade 7 is used to transport raw materials, and the scraper 11 is used to clean the raw materials on the inner wall of the screen drum 10 to avoid the raw materials adhering to the inner wall of the screen drum 10 and causing it to be blocked.

[0023] The drive assembly 5 is connected to the screen drum 10 and the spiral blade 7. The drive assembly 5 includes: a sun gear 504, a planetary gear 503, a ring gear 502, and a drive motor 501 that drives the sun gear 504 to rotate. The sun gear 504 is connected to the spiral blade 7, the ring gear 502 is connected to the screen drum 10, and the planetary gear 503 is installed on the planetary carrier.

[0024] In the present utility model, by starting the drive motor 501, the sun gear 504 drives the scraper 11 and the spiral blade 7 to rotate. The rotating spiral blade 7 can continuously send the raw materials to the screen drum 10 for screening. During screening, the rotating scraper 11 can clean the raw materials on the inner wall of the screen drum 10, thereby improving its screening efficiency and avoiding the situation where the raw materials adhere to the inner wall of the screen drum 10 and cause it to be blocked. At the same time, the sun gear 504 drives the ring gear 502 to rotate through the planetary gear 503, and the ring gear 502 drives the screen drum 10 to rotate. The rotation of the screen drum 10 can further improve its screening efficiency on the one hand, and on the other hand, it can also play a role in preliminary mixing of the raw materials.

[0025] A discharge port 4 is installed below the raw material pretreatment box 3 for discharging the pretreated raw materials. An observation window 6 is installed on the raw material pretreatment box 3 to facilitate viewing the pretreatment status of the raw materials.

The connecting component 9 includes: a belt unit 903, a rotating shaft 902, a main gear 904 installed on the rotating shaft 902, and a driven gear 901 engaged with the main gear 904. The driven gear 901 is coaxially connected to the stirring blade 8.

[0027] In the present invention, when the driving motor 501 is running, the rotating shaft 902 and the main gear 904 rotate through the drive of the belt unit 903, and the main gear 904 drives the driven gear 901 to rotate, so that the stirring blade 8 rotates to achieve the purpose of mixing and stirring the raw materials.

[0028] Working principle: Start the drive motor 501, the sun gear 504 drives the scraper 11 and the spiral blade 7 to rotate, and the raw materials in the feeding box 1 are continuously sent to the screen drum 10 by the spiral blade 7 for screening. During screening, the rotating scraper 11 can clean the raw materials on the inner wall of the screen drum 10, thereby improving its screening efficiency. At the same time, the sun gear 504 drives the ring gear 502 to rotate through the planetary gear 503, and the ring gear 502 drives the screen drum 10 to rotate. The rotation of the screen drum 10 can further improve its screening efficiency on the one hand, and on the other hand, it can also play a role in preliminary mixing of the raw materials. The screened raw materials fall into the raw material pretreatment box 3, and are driven by the belt unit 903, the rotating shaft 902 and the main gear 904 rotate, and the main gear 904 drives the driven gear 901 to rotate, so that the stirring blade 8 rotates to mix and stir the raw materials. The mixed and stirred materials can be discharged through the discharge port 4.
