The flow rate sensor 15 is installed in the docking bucket 14, and the sensing window 151 located on the flow rate sensor 15 is the effective sensing area through which the particles flow; the top of the docking bucket 14 is fixedly connected to the top of the short tube 2 through three positioning rods 16 distributed in a ring, and the top port of the docking bucket 14 is sealed and fixedly connected to the bottom port of the particle hopper 1; the hollow spiral bar 21 is located inside the ring block 18, and two convex annular surfaces 19 are provided on the upper and lower surfaces of the ring block 18, and a rope threading channel 20 is provided inside the two convex annular surfaces 19, and a portion of the thin steel wire rope 12 slides through the rope threading channel 20.

[0027] The inner ends of the arc tube 1 3 and the inner ends of the arc tube 2 4 are both located in the short tube 2, and the inner end ports of the arc tube 1 3 and the inner end ports of the arc tube 2 4 are both installed with sealing rings 11, and the sealing ring 11 and the thin steel wire rope 12 are in sealed sliding contact with each other, and the surface of the thin steel wire rope 12 is coated with lubricant; the inner wall of the rubber hose 17 is provided with a tear-resistant mesh structure, and the bottom end port of the rubber hose 17 is connected to one end port of the particle conduit 10, and the particle conduit 10 is fixedly connected to the bottom of the short tube 2 through a connecting structure; the shaft ends on both sides of the double groove wheel 13 are rotatably connected to the middle of the upper and lower circular walls in the winding box 5 through sealed bearings, and the winding box 5 is filled with lubricant; the upper and lower end ports of the hollow spiral bar 21 are provided with wear-resistant rings, and the corresponding parts of the hollow spiral bar 21 and the rubber hose 17 are an integrated structure of the same material; the back of the dual output shaft gearbox 8 is fixedly connected to the middle of the annular surface of the short tube 2 through a connecting plate 9.
