[0002] The existing auger conveying material, such as the solution with the authorization publication number CN219771021U, solves the blockage of the auger feed port by rotating the turntable 74 through the connecting rod 75 to drive the lower side of the stirring rod 76 to swing. Although it can solve the problem of feed port blockage, the following problems still exist:

[0003] 1. Since the feeding port will not be blocked by the stirring rod 76, when the blocked material is opened by the stirring rod 76, the material will quickly enter the feeding pipe, which will cause the material entering the feeding pipe to accumulate per unit time, which may easily cause the material to accumulate in the feeding pipe and affect the life of the feeding pipe.

[0004] 2. When conveying some materials that need to be conveyed at a uniform speed, it is difficult to achieve the effect of uniform material discharge by preventing the feed port from being blocked by the stirring rod 76. Summary of the invention

[0028] The specific implementation of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] Depend on Figures 1 to 9 The utility model comprises a conveying pipe 1 and a spiral blade 2. A feed port 3 is provided on the upper side of one end of the conveying pipe 1, and a discharge port 4 is provided on the lower side of the other end of the conveying pipe 1. A first cylinder 5 with upper and lower openings is fixed on the upper side of the feed port 3. The axis of the first cylinder 5 is placed up and down, and a bell mouth 6 is fixed on the upper end of the first cylinder 5.

[0030] A coaxial rotating shaft 7 is arranged in the middle of the first cylinder 5 and rotates around the axis. Two coaxial discs 8 are fixed on the rotating shaft 7. There is a gap between the two discs 8. A sector-shaped through hole 9 is respectively provided on the upper disc 8 and the lower disc 8. The projections of the two through holes 9 on the horizontal plane are symmetrical about the center of the rotating shaft 7. A plurality of sector plates 10 are fixed between two partition plates 10 and are evenly distributed about the circumference of the axis. The partition plates 10 divide the gap between the upper and lower discs 8 into a plurality of sector-shaped independent spaces.

[0031] A round rod 11 pointing to the axis of the rotating shaft 7 is rotated on the upper side of the upper disc 8 . The round rod 11 is located on the upper side of the through hole 9 of the upper disc 8 . A plurality of levers 12 pointing to the round rod 11 are fixed to the outer edge of the round rod 11 .

[0032] A coaxial second cylinder 13 is fixed to the middle of the first cylinder 5 via a plurality of flat rods 14. The upper end of the second cylinder 13 is conical, and the lower end of the second cylinder 13 is open.

[0033] A coaxial ring 15 is fixed to the upper end surface of the upper disk 8. The outer diameter of the ring 15 is the same as the outer diameter of the second cylinder 13. The upper end surface of the ring 15 fits with the lower end surface of the second cylinder 13 and can rotate relatively.

[0034] A fixed disk 16 is fixed to the lower side of the second cylinder 13, and a downward end face gear ring 17 is fixed to the lower side of the fixed disk 16. The inner end of the round rod 11 passes through the ring 15 and is placed inside the ring 15. A gear 18 is fixed to the end of the round rod 11 placed inside the ring 15, and the upper side of the gear 18 is meshed with the end face gear ring 17.

[0035] A fixing block 19 is fixed to the upper end surface of the disc 8 located on the upper side, and the outer end of the round rod 11 passes through the fixing block 19 and rotates inside the fixing block 19 .

[0036] The rotating shaft 7 is located between the two discs 8 and has a fixing ring 20. The outer edge of the fixing ring 20 is fixedly connected to the inner side of the partition 10. The upper and lower end surfaces of the fixing ring 20 fit with the corresponding discs 8 and can rotate relatively. A supporting disc 21 is fixed to the inner side of the fixing ring 20. The rotating shaft 7 passes through the supporting disc 21 and is rotatably connected to the supporting disc.

[0037] A first motor 22 is fixed on the upper side of the fixed disk 16 in the second cylinder 13 , and the rotating shaft 7 passes through the fixed disk 16 and is connected to the first motor 22 via a coupling.

[0038] The inner end of the first cylinder 5 is provided with two annular grooves 23, and the outer edge of the disc 8 is placed in a corresponding annular groove 23;

[0039] The annular groove 23 can ensure that the outer side of the disc 8 will not deform downward when the material is pressed downward.

[0040] The diameter of the outer edge of the through hole 9 is smaller than the diameter of the inner edge of the first cylinder 5 , and the diameter of the inner edge of the through hole 9 is the same as the diameter of the outer edge of the second cylinder 13 .

[0041] The number of the partitions 10 is greater than three.

[0042] It is worth mentioning that a second motor 24 is fixed to one end of the delivery pipe 1 , and the second motor 24 is connected to the rotating rod in the spiral blade 2 via a coupling.

[0043] When the utility model is used, the delivery pipe 1 is placed at a designated position, and then the first motor 22 and the second motor 24 are started to rotate the spiral blade 2 and the disc 8;

[0044] Afterwards, the material to be conveyed is poured into the bell mouth 6. Most of the material will first fall on the upper disc 8, and some of the material will fall on the lower disc 8 through the through holes 9 on the upper disc 8, so that some of the material is placed between the two discs 8. Since the through holes 9 on the two discs 8 are symmetrical about the axis of the rotating shaft 7 in horizontal projection, the material will not fall into the conveying pipe 1 immediately, and the material will not rotate with the rotation of the disc 8 due to the obstruction of the partition 10, so that the material will remain between the two adjacent partitions 10. When the disc 8 on the lower side rotates to between the two adjacent partitions 10 where the material is stored, the material will fall into the conveying pipe 1 at a uniform speed along the through holes 9 on the lower disc 8, and be conveyed to the discharge port 4 by the spiral blades 2;

[0045] When the disc 8 rotates, the disc 8 drives the round rod 11 to rotate, and the end face gear ring 17 causes the gear 18 to rotate, thereby driving the round rod 11 to rotate, and the lever 12 rotates with the round rod 11. The lever 12 can knock the material on the upper side into the through hole 9 of the disc 8 on the upper side, which can solve the problem that the material accumulates in the first round tube and the bell mouth 6 and cannot fall.

[0046] 1. The utility model firstly knocks the material into the through hole 9 of the upper disc 8 through the lever 12, which can solve the problem that the material is accumulated in the first circular tube and the bell mouth 6 and cannot fall down;

[0047] Furthermore, the through holes 9 on the two discs 8 are symmetrical about the axis of the rotating shaft 7 in horizontal projection, so the material will not fall into the conveying pipe 1 immediately, and the material will not rotate with the rotation of the disc 8 due to the obstruction of the baffle 10, so that the material will remain between the two adjacent baffles 10. When the disc 8 on the lower side rotates to between the two adjacent baffles 10 where the material is stored, the material will no longer be squeezed by the material on the upper side of the disc 8, so that the material will no longer block the first cylinder 5, and the material will fall into the conveying pipe 1 at a uniform speed along the through holes 9 on the lower disc 8, so as to prevent a large amount of material from falling into the conveying pipe 1 at one time and causing the material in the conveying pipe 1 to be blocked.
