[0023] The conveying assembly 6 is composed of six conveying rollers and a conveying belt. The six conveying rollers are rotatably connected in the box body 2, and the conveying belt is sleeved between the six conveying rollers.

[0024] The transmission mechanism includes a servo motor 71, the servo motor 71 is connected to the base frame 1 by bolts, the output shaft of the servo motor 71 is connected to a driving pulley 72 by a flat key, a rotating shaft 721 is welded to the conveying assembly 6, and a transmission pulley 73 is connected to the rotating shaft 721 by a flat key. A convex column is provided on the side of the transmission pulley 73 away from the box body 2, and a belt 74 is sleeved between the driving pulley 72 and the transmission pulley 73.

[0025] The quantitative feeding mechanism includes a flap 81, and the box body 2 is rotatably connected to the flap 81, and the flap 81 is located below the feed hopper 3. A torsion spring 82 is connected between one end of the flap 81 and the outer wall of the box body 2 through a hook, and the torsion spring 82 is sleeved on the flap 81. A short rod 83 is welded to the other end of the flap 81, and the short rod 83 is located outside the box body 2. A cam 84 is connected to the rotating shaft 721 through a flat key.

[0026] At first, the flap 81 blocks the feed hopper 3. First, the staff pours the chemical particles into the feed hopper 3, and then starts the servo motor 71 and the microwave dryer 5. The servo motor 71 drives the active pulley 72 to rotate, and the active pulley 72 drives the transmission pulley 73 to rotate through the belt 74. The rotation of the transmission pulley 73 drives the rotating shaft 721 to rotate, and the rotation of the rotating shaft 721 drives the cam 84 and the conveying assembly 6 to rotate, and the cam 84 contacts the short rod 83.

At the same time, the conveying component 6 will convey the chemical particles, and the microwave dryer 5 will perform microwave drying on the chemical particles on the conveying component 6.
