When the vibrating plate 304 reciprocally slides on the dredging column 302, the vibrating plate 304 knocks on the drying cylinder 102. A cam 309 is rotatably arranged inside the dredging column 302. When the cam 309 rotates, it drives the vibrating plate 304 to reciprocally slide on the dredging column 302, realizing the knocking on the drying cylinder 102 and improving the falling speed of the materials inside the drying cylinder 102.

[0032] Working principle: When working, place the materials to be dried in the feeding box 201, drive the seventh baffle 202 and the second baffle 113 to move. The seventh baffle 202 releases the closing of the material conveying pipe 203, and the second baffle 113 releases the closing of the first feeding port 107. Subsequently, drive the second push plate 204 to slide on the feeding box 201. The second push plate 204 pushes the materials in the feeding box 201 into the drying cylinder 102 through the material conveying pipe 203. After the feeding of the materials is completed, drive the second baffle 113 to close the first feeding port 107, and drive the seventh baffle 202 to close the feeding box 201. Inject heating liquid into the flow tank 111 through the liquid inlet 125. The liquid heats the materials in the drying cylinder 102 in the flow tank 111.

The stirring motor 106 drives the stirring blades 108 to rotate, drives the stirring column 114 to rotate, and start the air outlet 110 to work. The air outlet 110 blows air to the materials in the drying cylinder 102. At this time, the stirring blades 108, the air outlet 110, and the stirring column 114 realize the turning and drying of the materials in the drying cylinder 102.

[0033] During the drying process, the drying degree of the material is detected. The sampling box 121 is driven to slide on the sampling rack 120, and the adjusting ring 124 is driven to rotate inside the drying cylinder 102. The adjusting ring 124 drives the sampling box 121 to rotate inside the drying cylinder 102. When the sampling box 121 reaches the sampling position, the fifth baffle 122 is driven to move, and the fifth baffle 122 releases the enclosure of the sampling box 121. At this time, the material enters the sampling box 121. The sampling box 121 and the adjusting ring 124 are continuously driven to move to change the sampling position and increase the sample diversity. After sampling is completed, the adjusting ring 124 is driven to rotate. The adjusting ring 124 drives the sampling box 121 to align with the second feed inlet 118.

The first push plate 117 is driven to move, and the first push plate 117 pushes the material in the sampling pipe 112 into the detection box 103. The humidity detector 115 detects the drying degree of the material in the detection box 103. If the drying degree of the material in the detection box 103 meets the standard, the third baffle 116 is driven to rotate on the detection box 103, and the third baffle 116 releases the enclosure of the detection box 103. The material falls into the adjusting rack 301. If the material in the detection box 103 does not meet the standard, the fan on the return pipe 104 is driven to suck the material in the detection box 103 into the drying cylinder 102 to re-dry the non-compliant material, and the drying power of the material is adjusted in real time according to the drying state of the material.

[0034] During the drying process, if it is necessary to continue feeding materials without shutting down the drying component 1, the second baffle 113 is driven to enclose the first feed inlet 107, the seventh baffle 202 is driven to release the enclosure of the conveying pipe 203, the second push plate 204 is driven to slide on the feeding box 201, and the second push plate 204 pushes the material in the feeding box 201 into the conveying pipe 203.

The second baffle 113 is driven to rotate, and the second baffle 113 releases the enclosure of the first feed inlet 107. At this time, the material in the conveying pipe 203 enters the drying cylinder 102 through the first feed inlet 107, completing the feeding of the material in the drying cylinder 102 during the drying process.

[0035] When the drying in the drying cylinder 102 is completed, drive the first baffle 109 to slide in the drying cylinder 102, and the first baffle 109 releases the sealing of the drying cylinder 102. At this time, the material drops from the drying cylinder 102 into the adjusting frame 301. When the dropping speed of the material in the drying cylinder 102 becomes low or is about to be discharged completely, drive the adjusting frame 301 to slide on the drying cylinder 102. The adjusting frame 301 drives the dredging column 302 to align with the drying cylinder 102.
