A motor 28 is installed on the upper surface of the drying drum 1. The end of the output shaft of the motor 28 is fixedly connected to the top of the rotating shaft 27. The motor 28 drives the second gear 26 to rotate through the rotating shaft 27. Gear 26 drives the rotating rod 22 to rotate via the first gear 25. The rotating rod 22 drives the stirring rod 21 to rotate via the guide rod 23, causing the stirring rod 21 to stir the raw materials. This, combined with the spiral ceramic heating rod 4, stirs and dries the raw materials. The driving end of the cylinder 24 drives the stirring rod 21 to rise and adjust its position, thus improving the stirring effect. A connecting rod 29 is fixedly installed at the bottom of the stirring rod 21, and a push rod 210 is fixedly installed at the bottom of the connecting rod 29. Rotation of the connecting rod 29 drives the push rod 210 to rotate, causing the push rod 210 to pulverize... The material is moved and discharged. A limiting plate 211 is fixedly provided on the outside of the stirring rod 21. The upper surface of the limiting plate 211 is in contact with the bottom end of the guide rod 23. The limiting plate 211 can limit the stirring rod 21. A support plate 212 is fixedly provided at the top of the drying barrel 1. The cylinder 24 is installed on the upper surface of the support plate 212. The cylinder 24 can be easily installed through the support plate 212.

The motor 28 can be easily installed through the mounting plate 213.
[0017] The discharge assembly 3 includes a guide plate 31. A discharge port 32 is provided at the bottom of the drying barrel 1. One end of the guide plate 31 is rotatably installed in the discharge port 32. Symmetrically distributed baffles 33 are fixed on the lower surface of the drying barrel 1. The baffles 33 are located on both sides of the discharge port 32. A plug rod 34 is movably inserted through the outside of the drying barrel 1. One end of the plug rod 34 is threaded into one end of the guide plate 31. After the plug rod 34 is removed, the guide plate 31 flips downward along the rotatable connection and pushes the raw material into the discharge port 32 for discharge through the push rod 210. The baffles 33 guide the raw material, which facilitates the discharge of the raw material. A positioning rod 35 is fixed on the opposite side of the baffles 33. The positioning rod 35 can be used to position the guide plate 31.
[0018] Working principle: First, the raw materials are added through the feed inlet of the drying drum 1, and then the motor 28 is started, so that the motor 28 starts to work. The end of the output shaft of the motor 28 drives the rotating shaft 27 to rotate, the rotating shaft 27 drives the second gear 26 to rotate, the second gear 26 drives the first gear 25 to rotate, the first gear 25 drives the rotating rod 22 to rotate, and the rotating rod 22 drives the stirring rod 21 to rotate through the guide rod 23, so that the stirring rod 21 stirs the raw materials. Then, the spiral ceramic heating rod 4 is energized, so that the spiral ceramic heating rod 4 heats up and heats and dries the raw materials. In this way, the raw materials can be stirred and dried.
[0019] When it is necessary to adjust the height of the stirring rod 21, turn off the motor 28 and start the cylinder 24 so that the cylinder 24 starts to work. The drive end of the cylinder 24 drives the stirring rod 21 to rise and keeps the stirring rod 21 moving stably through the guide rod 23. In this way, the position of the stirring rod 21 can be adjusted to meet the stirring needs at different heights.
[0020] After drying is complete, the cylinder 24 is activated to control the stirring rod 21 to descend, causing the stirring rod 21 to drive the push rod 210 to fit against the bottom of the drying drum 1. Then, the plug rod 34 is rotated to move the plug rod 34 out of the guide plate 31. The guide plate 31 flips down along the rotating connection and fits against the positioning rod 35. Next, the motor 28 controls the stirring rod 21 to rotate, which drives the connecting rod 29 to rotate. The connecting rod 29 drives the push rod 210 to rotate, causing the push rod 210 to push the dried raw material into the discharge port 32. The dried raw material is discharged from the guide plate 31 into the outer container and guided by the baffle 33, which facilitates the discharge.
