A bearing plate 3 is mounted between the upper ends of the four support columns 2. Two discharge pipes 4 are embedded in the upper wall of the bearing plate 3. An assembly box 5 is mounted on the upper end of each discharge pipe 4. Electric cylinders 6 are mounted on the two inner side walls of each assembly box 5. A limit frame 7 is mounted on the telescopic end of each electric cylinder 6. A first bearing 8 is embedded in the upper wall of each assembly box 5. A first connecting pipe 9 is embedded in each first bearing 8. The bearing plate 3 is located on the two assembly boxes 5. The support frame 10 is equipped with two second bearings 11 embedded in its lower wall. Each second bearing 11 contains a second connecting pipe 12. Each first connecting pipe 9 is connected to each second connecting pipe 12. A chamber placement frame 13 is mounted on the upper wall of the support frame 10, above each second connecting pipe 12. Each chamber placement frame 13 has a chamber 14 mounted on it. A third bearing 15 is embedded in the lower wall of each chamber 14. Each second connecting pipe 12 is connected to each third bearing 15. Each second connecting pipe 12 is located below each chamber 14. Inside the wall; on the upper wall of the support plate 3 and behind each assembly box 5, assembly columns 16 are respectively installed. A servo motor 17 is embedded in the upper end of each assembly column 16. A drive gear 18 is installed on the drive end of each servo motor 17. A driven gear 19 is installed on each first connecting pipe 9. Each driven gear 19 meshes with each drive gear 18. A clearing structure is installed inside each first connecting pipe 9. Support rods 20 are installed between each assembly box 5 and the support plate 3 and on both sides of each discharge pipe 4. Each clearing structure includes a fixing frame 2. 1. Extension rod 22 and stirring head 23: Each fixed frame 21 is placed inside each first connecting pipe 9, each extension rod 22 is placed on each fixed frame 21, each extension rod 22 is located in each first connecting pipe 9 and each second connecting pipe 12 respectively, and each stirring head 23 is placed at the upper end of each extension rod 22 and located in each second connecting pipe 12; four pads 24 are installed on the lower wall of the mounting plate 1; a sealing rubber layer 25 is installed on the opposite wall of each pair of limiting frames 7, and a rubber sealing ring 26 is installed on each first bearing 8 and third bearing 15 respectively; The specific working principle is as follows: The operator connects the discharge pipe 4 on the support plate 3 of this device to the conveying equipment, connects the external power supply to power the device, and controls the operation through the programmable controller installed on it. During the feeding process, the electric cylinder 6 in one assembly box 5 pushes the limit frame 7 to move relative to each other, and the limit frames 7 contact each other to make the sealing rubber layer 25 close and block it. The electric cylinder 6 in the other assembly box 5 drives the limit frame 7 installed on its telescopic end to retract, forming a supply channel. The servo motor 17 in the corresponding assembly column 16 drives the drive gear 18 installed on its drive end to rotate. The drive gear 18 then drives the driven gear 19 that meshes with it to rotate, thereby making the first connecting pipe 9 rotate in the first bearing 8. The second connecting pipe 12 connected to the first connecting pipe 9 rotates in the second bearing 11 on the support frame 10 and the third bearing 15 in the lower wall of the chamber 14.

The servo motor 17 adjusts its rotation speed in real time according to the changes in the conveying equipment. Before the material in the chamber 14 installed on the chamber placement frame 13 is used up, the operator controls the operation through the programmable controller installed on it. The running servo motor 17 stops running and stands by. At the same time, the retracting electric cylinder 6 pushes the limit frame 7 to move relative to close it. The closed limit frame 7 is pulled open by the electric cylinder 6 to form a discharge channel. The above steps are repeated to continue the material rotation and unblocking discharge, realizing rapid discharge switching and maintaining the smooth operation of the equipment.

The mounting plate 1 and the pillar 2 are used for support and placement. The pad 24 is used to assist in support and prevent uneven ground.
