Two discharge pipes 15 are connected to the bottom of the mixing bin 3, and an electric valve 16 is installed on the discharge pipe 15. The bottom of the discharge pipe 15 is connected to a screw conveyor 10, and the bottom of the screw conveyor 10 is respectively connected to a cleaning pipe 8 and a discharge component 9; the spiral ribbon 17 is widened to make it easier to collect and discharge materials; the speed of the spiral ribbon 17 is controlled by the frequency conversion motor 13, and the corresponding speed is set according to different product indicators to make the product mixing more uniform and effective.

[0021] As a technical optimization solution of the present invention, a manual valve 12 is installed on the side of the negative pressure feeding pipe 4 close to the flexible conveying pipe 11, an observation window is opened at the center of the top of the mixing bin 3, and a limit frame is connected to the top of the mixing bin 3 and located on the outside of the observation window, and a T-shaped cover plate 5 is placed on the top of the limit frame; the feed amount of the negative pressure feeding pipe 4 can be controlled by the manual valve 12.

[0023] As a technical optimization solution of the present invention, the bottom of the outer part of the discharge tube 91 is provided with an upper positioning ring plate 92, and the bottom of the outer part of the telescopic tube 98 is provided with a lower positioning ring plate 93. Both sides of the bottom of the upper positioning ring plate 92 are connected with an electric telescopic rod 99, and the bottom of the telescopic end of the electric telescopic rod 99 is connected to the lower positioning ring plate 93; through the cooperation of the electric telescopic rod 99, the lower positioning ring plate 93 and the upper positioning ring plate 92, the telescopic tube 98 can be stretched when the electric telescopic rod 99 is extended, thereby lowering the discharge position.

[0024] As a technical optimization solution of the present invention, arc-shaped support blocks 97 are connected to both sides of the bottom of the lower positioning ring plate 93, and an electric telescopic rod 2 96 is provided through the arc-shaped support block 97, and the telescopic end of the electric telescopic rod 2 96 is connected to a splint 95; through the splint 95, the splint 95 can be driven to move toward the flexible discharge head 94 when the telescopic end of the electric telescopic rod 2 96 is extended, thereby sealing the discharge port of the flexible discharge head 94.

As the material level in the container below the flexible discharge head 94 increases during the discharge process, the telescopic end of the electric telescopic rod 1 99 gradually begins to retract. When the container below is full of material, the telescopic end of the electric telescopic rod 2 96 extends, and the flexible discharge head 94 is closed using the clamp 95. The existing container is removed and replaced with a new one. The telescopic end of the electric telescopic rod 2 96 then retracts, and the clamp 95 stops clamping the material from the flexible discharge head 94. The telescopic end of the electric telescopic rod 1 99 extends prematurely, lowering the discharge height of the flexible discharge head 94. During the material addition process, the bag filter 6 is in operation, and the dust generated during the feeding process is filtered and processed by the bag filter 6. The retained dust falls back into the mixing bin 3. The use of negative pressure feeding effectively avoids the waste of material dust and improves the working environment of the operator.
