[0017] The working principle of the present utility model is as follows. When in use, the materials transported by the conveying equipment enter the shell through the feed inlet. When discharging from a certain discharge port is required, the positioning mechanism can be used to position the rotary discharge pipe. The specific steps are as follows: Turn on the power supply of the electromagnet on the positioning rod corresponding to this discharge port to connect the electromagnet, and then start the servo motor to drive the rotating shaft to rotate a certain angle. When the telescopic rod assembly rotates to near the positioning sleeve with the energized electromagnet, the electromagnet will attract the iron inner telescopic rod and suck the end of the inner telescopic rod into the inner cavity of the positioning sleeve, thereby positioning the telescopic rod assembly. At the same time, the servo motor stops rotating, thus completing the positioning of the rotary discharge pipe. After the rotary discharge pipe is positioned with the discharge port, start discharging at this discharge port. After the discharging at this discharge port is completed, start the positioning and discharging work for the next discharge port. The electromagnet on the previous positioning rod loses power, and the inner telescopic rod contracts back into the outer telescopic rod under the resilience of the tension spring. Subsequently, the electromagnet on the next positioning rod gets power. When the servo motor drives the telescopic rod assembly to rotate to a position near the positioning sleeve of the next positioning rod through the rotating shaft, it attracts and stretches the inner telescopic rod, so that the rotary discharge pipe can correspond to the next discharge port. Running in this cycle, discharging from different discharge ports is realized.

[0018] The beneficial effects of the present utility model are as follows. Through the positioning mechanism, the rotary discharge pipe can be positioned, which is convenient for the rotary discharge pipe to align with the discharge port, reduces the occurrence of material mixing and cross-flow between each batching bin, and provides convenience for production. In addition, by driving the brush to rotate through the rotating shaft, it is convenient to quickly brush the materials accumulated in the lower cone body and discharge the remaining materials from the remaining material outlet, avoiding pollution between raw materials and improving the cleanliness inside the shell.
