[0030] The regulating mechanism 4 includes a discharge section 41 and an regulating section 42;

[0031] The adjustment section 42 is located on the outer side of the discharge section 41.

[0032] The feeding section 31 includes a feed inlet 311, and a feed pipe 312 is connected to the bottom end of the feed inlet 311. The right end of the feed pipe 312 is rotatably connected to the left side of the drum mixing dryer body 2. A U-shaped plate 313 is provided on the left end of the feed pipe 312, and the U-shaped plate 313 is fixedly connected to the feed pipe 312.

[0033] A motor 314 is provided on the inner side of the U-shaped plate 313. The motor 314 is fixedly connected to the U-shaped plate 313. A rotating rod 315 is provided on the output end face of the motor 314. The rotating rod 315 is fixedly connected to the motor 314. The rotating rod 315 passes through the inner side of the feed pipe 312 and extends to the inner side of the drum mixing dryer body 2. The surface of the rotating rod 315 is rotatably connected to the inner wall of the feed pipe 312 through a bearing seat.

[0034] The lifting section 32 includes a spiral blade 321, which is sleeved on the surface of the rotating rod 315 and is fixedly connected to the rotating rod 315. A fixing sleeve 322 is provided on the right side of the spiral blade 321, which is sleeved on the surface of the rotating rod 315 and is fixedly connected to the rotating rod 315.

[0035] The surface of the fixed sleeve 322 is provided with lifting blades 323, which are fixedly connected to the fixed sleeve 322. The outer side of the lifting blades 323 is provided with scrapers 324, which are fixedly connected to the lifting blades 323. A support frame 325 is provided on the left side of the scraper 324, which is fixedly connected to the base 1. The top surface of the support frame 325 is fixedly connected to the bottom surface of the feed pipe 312.

[0036] Furthermore, in this embodiment, the material enters the feed pipe 312 through the feed inlet 311 in the feed section 31 via the feeding mechanism 311. The motor 314 is started in the opposite direction, and the motor 314 drives the rotating rod 315 to rotate. The rotating rod 315 drives the spiral blade 321 to rotate. The rotating spiral blade 321 feeds the material from the feed pipe 312 into the drum mixing dryer body 2. At the same time, the drum mixing dryer body 2 is started to rotate in the forward direction. When the motor 314 rotates, it drives the rotating rod 315 to rotate synchronously. The rotating rod 315 drives the fixed sleeve 322, the lifting blade 323, and the scraper 324 to rotate synchronously. While the drum mixing dryer body 2 is rotating, the lifting blade 323 stirs and lifts the material, and the scraper 324 assists in processing the material.

[0037] Furthermore, in this embodiment, the material enters the feed pipe 312 through the feed inlet 311 in the feed section 31 via the feeding mechanism 3. The motor 314 is started in the opposite direction, and the motor 314 drives the rotating rod 315, which in turn drives the spiral blades 321, thereby feeding the material into the drum mixing dryer body 2. At the same time, the drum mixing dryer body 2 is started to rotate in the forward direction. At this time, the rotation of the motor 314 drives the rotating rod 315 to rotate synchronously, thereby driving the fixed sleeve 322, the lifting blades 323, and the scraper 324 to rotate synchronously. This allows the material in the drum mixing dryer body 2 to be stirred and lifted while the drum mixing dryer body 2 is rotating, so that the material is more fully mixed in the drum mixing dryer body 2, avoiding material accumulation or local overheating, and preventing the material from sticking to the inner wall of the drum mixing dryer body 2.

[0038] Example 2:

[0039] Please see Figure 1 , Figure 2 , Figure 4Furthermore, based on Embodiment 1, the following is further obtained: the discharge section 41 includes a discharge box 411, which is fixedly connected to the right side of the base 1 and rotatably connected to the right side of the drum mixing dryer body 2. A discharge pipe 412 is provided at the bottom end of the discharge box 411. A sliding groove is provided on the inner side of the discharge pipe 412, and an adjusting plate 413 is provided on the inner side of the sliding groove. The adjusting plate 413 is slidably connected to the sliding groove and extends through to the outside of the discharge pipe 412. The adjusting plate 413 is slidably connected to the inner wall of the discharge pipe 412.

[0040] The adjustment part 42 includes a side plate 421, which is fixedly connected to the outer side of the adjustment plate 413. Each outer side of the side plate 421 is provided with a fixing block 422, which is fixedly connected to the side plate 421. A cylinder 423 is provided on the inner side of the fixing block 422, which is fixedly connected to the fixing block 422.

[0041] Furthermore, in this embodiment, through the adjustment mechanism 4, the material after drying is dropped into the discharge box 411 in the discharge section 41 through the drum mixing dryer body 2 via the discharge box 411. When it is necessary to adjust the size of the discharge opening, the cylinder 423 is activated. The cylinder 423 pushes the fixed block 422 and the side plate 421. The side plate 421 moves under the push of the cylinder 423. The side plate 421 drives the adjustment plate 413 to move. The adjustment plate 413 slides in the slide groove. The size of the discharge opening is changed by the movement of the adjustment plate 413.

[0042] Furthermore, in this embodiment, the drying material is discharged through the discharge box 411 in the discharge section 41 via the adjustment mechanism 4. The dried material falls into the discharge box 411 after passing through the drum mixing dryer body 2. When the size needs to be adjusted, the cylinder 423 is activated. The cylinder 423 pushes the fixing block 422 and the side plate 421, thereby causing the side plate 421 to drive the adjustment plate 413 to slide with the chute, thereby adjusting the opening size. The material is then discharged through the discharge pipe 412. The position of the adjustment plate 413 can be adjusted according to the characteristics of the material and the drying requirements.

[0043] In operation, material enters the feed pipe 312 through the feed inlet 311 of the feed section 31 via the feeding mechanism 3. The motor 314 is started in the reverse direction, driving the rotating rod 315 to rotate. The rotating rod 315 then drives the spiral blades 321 to rotate, which in turn feeds the material from the feed pipe 312 into the drum mixing dryer body 2. Simultaneously, the drum mixing dryer body 2 is started to rotate in the forward direction. The rotation of the motor 314 drives the rotating rod 315 to rotate synchronously, which in turn drives the fixed sleeve 322, the lifting blades 323, and the scraper 324 to rotate synchronously in the drum mixing... While the dryer body 2 rotates, the lifting blades 323 stir and lift the material, and the scraper 324 assists in processing the material. Through the adjustment mechanism 4, the dried material falls into the discharge box 411 in the discharge section 41 through the drum mixing dryer body 2. When it is necessary to adjust the size of the discharge opening, the cylinder 423 is started. The cylinder 423 pushes the fixed block 422 and the side plate 421. The side plate 421 moves under the push of the cylinder 423. The side plate 421 drives the adjustment plate 413 to move. The adjustment plate 413 slides in the chute. The size of the discharge opening is changed by the movement of the adjustment plate 413.
