[0027] The second servo motor 6 and the spiral fan blade 5 are rotationally connected through a coupling. On one side of the feeding box body 4, a discharge pipe 7 is installed. On the right side of the feeding box body 4, a transportation pipe 8 is hinged. On the right side of the feeding box body 4, an electric push rod 9 is installed. On the right side of the electric push rod 9, a roller 10 is installed and the roller 10 is slidably connected to the bottom of the transportation pipe 8. On the left side of the feeding box body 4, a material box body 11 is installed. At the top of the material box body 11, a feeding pipe 12 is installed. Inside the cavity of the material box body 11, an inclined plate 13 is installed and is used to transport the materials in the material box body 11 into the inside of the feeding box body 4 to realize the transfer process.

[0028] In the embodiment of the present utility model, the start of the first servo motor 3 can drive the spiral fan blade 5 to rotate. With the rotation of the spiral fan blade 5, the materials inside the feeding box body 4 can be transported upwards; when the materials rise to the top of the cavity of the feeding box body 4, the materials will flow out through the discharge pipe 7.

[0029] Please refer to Figures 1 - 4 The fixing mechanism includes a fixing frame 14. Inside the cavity of the fixing frame 14, a fixing block 15 is slidably connected. Inside the cavity of the fixing frame 14, a threaded hole 16 is opened. Inside the threaded hole 16, a threaded rod 17 is threadedly connected.

Then, in cooperation with the start of the first servo motor 3, the start of the first servo motor 3 can drive the spiral fan blade 5 to rotate. As the spiral fan blade 5 rotates, the material inside the feeding box body 4 can be transported upward; when the material rises to the top of the inner cavity of the feeding box body 4, the material will flow out through the discharge pipe 7. Through the cooperation of the electric push rod 9 and the transport pipe 8, start the electric push rod 9, and the electric push rod 9 contracts, which can adjust the angle between the transport pipe 8 and the feeding box body 4; when the angle between the transport pipe 8 and the feeding box body 4 is larger, the height of the material transported by the transport pipe 8 is higher, and when the angle between the transport pipe 8 and the feeding box body 4 is smaller, the height of the material transported by the transport pipe 8 is lower at this time, and different height material processing equipment and feeding equipment can be matched.
