In this embodiment, two sets of opposite hollow tubes 7 are provided on a set of support rings 8. The purpose is to allow more mixed raw materials to enter at one time. The support ring 8 is provided with a discharge port 9. There are two sets of discharge ports 9, which are arranged opposite to each other. In this embodiment, several sets of receiving components are provided, which are arranged along the length direction of the support rod 5.
[0025] A ball screw 10 is arranged along the length of the support rod 5 inside the cavity 6. The upper end of the ball screw 10 is rotatably connected to the inner wall of the barrel 2. The ball screw 10 is concentrically arranged with each set of support rings 8. A slider 11 is slidably arranged on the ball screw 10. A driving plate 12 is horizontally slidably arranged on the lower side of the slider 11. In this embodiment, the outer walls of the driving plate 12 have protrusions at both ends. An opening 13 is opened in the middle of the support ring 8 for the slider 11 to pass through, and a groove 14 is opened in the inner wall of the opening 13 for the protrusion to pass through. A driving rod 15 is arranged parallel to the side of the ball screw 10. An arc groove 16 is opened on the slider 11. The upper end of the driving rod 15 is oriented around the central axis of the ball screw 10 with the inner wall of the barrel 2. The sliding connection is used, and the lower end of the driving rod 15 passes through the arc groove 16 and the driving plate 12 in sequence. A hollow storage box 17 is provided below the support ring 8. The opening 13 of the storage box 17 is located directly below the material leakage port 9 of the support ring 8. A material conveying pipe 18 is connected to the lower end of the storage box 17. A visual guide is provided outside the support rod 5. The material conveying pipes 18 connected to each group of storage pipes are respectively connected to the main pipe 20. In this embodiment, the material conveying pipe 18 is gradually inclined downward away from the storage box 17. A guide platform 19 is built into the storage box 17. The upper side of the guide platform 19 is an inclined surface, and its lowest end faces the connection between the material conveying pipe 18 and the storage box 17. The lower end of the main pipe 20 extends out of the barrel 2.
[0026] A T-shaped linkage rod 22 is inserted through the middle of the cover 4. One end of the linkage rod 22 passes through the cover 4 and is located inside the barrel 2, opposite to the ball screw 10. The ball screw 10 has a slot 23 on the side facing the cover 4. A locking block 24 is provided on the end of the linkage rod 22 inside the barrel 2, which engages with the slot 23. A movable groove 25 is provided on the cover 4. The movable groove 25 is arc-shaped and is opposite to the arc-shaped groove 16 on the slider 11 inside the cavity 6. An L-shaped connecting plate 26 is slidably installed at the moving groove 25. One end of the connecting plate 26 is located outside the cover 4, and the other end is located inside the barrel 2, opposite to the driving rod 15. The connecting plate 26 has an insertion hole 27 on the side facing the driving rod 15 for insertion and mating with the driving rod 15. The linkage rod 22 and the connecting plate 26 are each screwed with a top fixing bolt 28 at the end of the linkage rod 22 and the connecting plate 26 located outside the barrel 2. The purpose is to facilitate the personnel to limit and fix the linkage rod 22 and the connecting plate 26.
[0027] A ring-shaped bottom plate 29 is provided on the inner wall of the middle part of the storage box 17. A torsion spring 30 is provided on the bottom plate 29 and connected to the lower side of the support ring 8. The inner diameter of the bottom plate 29 is large enough to allow the concentric drive plate 12 to pass through.
[0028] When personnel do not need to sample the raw materials mixed inside the barrel 2, the torsion spring 30 is in an unstressed state, the leakage port 9 on the support ring 8 is not aligned with the hollow tube 7, the top bolt 28 is in position to fix the linkage rod 22 and the connecting plate 26 to the cover 4, the locking block 24 on the linkage rod 22 is inserted into the slot 23 of the ball screw 10, and one end of the driving rod 15 is inserted into the insertion hole 27 on the connecting plate 26. Thus, when the barrel 2 is driven to mix the raw materials, the ball screw 10 and the driving rod 15 will not be driven, and the support ring 8 is kept in a certain position by the torsion spring 30 and will not be driven by inertia to rotate too much.
[0029] When personnel need to sample the mixed raw materials at a certain height inside barrel 2, first stop the working arm 3 to pause the mixing in barrel 2, then loosen the top fixing bolt 28 on the connecting plate 26, start rotating the connecting plate 26, drive the ball screw 10, and the slider 11 on the ball screw 10 starts to slide. When it slides to a suitable height and is located in the opening 13 of the support ring 8 at this height, the driving plate 12 under the slider 11 also enters the opening 13 of the support ring 8, and its protrusion is located in the groove 14 of the opening 13. Then, tighten the top fixing bolt 28 on the connecting plate 26 and loosen the connecting plate 26. The top bolt 28 on 6 starts to rotate the connecting plate 26. In this embodiment, the connecting plate 26 is rotated 90 degrees. The connecting plate 26 indirectly drives the driving plate 12 to rotate around the central axis of the support ring 8 through the driving rod 15. The support ring 8 is driven synchronously, and the torsion spring 30 begins to store energy. The hollow tube 7 at this height begins to transport the mixed raw materials at this height in the barrel 2 into the storage box 17 under the support ring 8 through the discharge port 9. The raw materials are output from the main pipe 20 through the guide platform 19 and the conveying pipe 18. Personnel collect the raw materials by placing the storage bucket (not shown in the attached figure) in the main pipe 20.
[0030] It should be noted that when personnel collect the contents, the position of the container 2 should be adjusted so that the end with the cap 4 is facing downwards.
[0031] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
