[0027] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0029] Example 1:
[0030] Please refer to Figure 1-4 A spiral conveying pump includes a hollow base frame 1, with mounting side plates 2 fixed on both sides of the hollow base frame 1, and a bearing support shaft 3 fixed between the two mounting side plates 2. The bearing support shaft 3 is located at one end inside the hollow base frame 1, and a conveying bracket 4 is rotatably connected to the outside of the bearing support shaft 3. The bottom end of the conveying bracket 4 away from the bearing support shaft 3 is in contact with the hollow base frame 1, and a motor device 5 and a conveying pipe 6 are respectively installed on the inner side of the conveying bracket 4.
[0031] In order to enable the conveying support 4 to be lifted and adjusted around the bearing support shaft 3, so that the material outlet of the conveying pipe 6 can be conveyed to a higher position, the upper ends of both sides of the conveying support 4 are fixed with positioning support rods 11, the lower end of the hollow base frame 1 is fixed with a support base 13, a rotating shaft 14 is rotatably connected to the center of the inner side of the support base 13, a connecting rod assembly is provided between the rotating shaft 14 and the two positioning support rods 11, and a drive assembly is provided on the inner side of the support base 13 and outside the rotating shaft 14.
[0032] Specifically, the linkage assembly includes a first guide rod 12, and the outer side of each positioning support rod 11 is rotatably connected to the first guide rod 12. The outer sides of the rotating shaft 14 are fixed with second guide rods 15. The inner side of the end of each second guide rod 15 away from the rotating shaft 14 is fixed with a mounting guide post 16. The end of the first guide rod 12 away from the positioning support rod 11 is located outside the mounting guide post 16 and is rotatably connected to the mounting guide post 16.
[0033] A lever base frame 17 is fixed at the center of the outer side of the rotating shaft 14. The drive assembly includes a hydraulic telescopic rod 21. One end of the support base 13 is equipped with a hydraulic telescopic rod 21. The telescopic end of the hydraulic telescopic rod 21 is fixedly connected to a push plate 20. By driving the hydraulic telescopic rod 21, the push plate 20 is moved to push the lever base frame 17, which facilitates the second guide rod 15 to rotate around the rotating shaft 14.
[0034] Example 2:
[0035] The screw conveyor pump provided in Example 1 is further optimized, specifically, as follows: Figure 3-4 As shown, in order to guide the horizontal movement of the push plate 20 and make its movement more stable, guide posts 19 are fixed on both sides of the inner side of the support base 13. The push plate 20 is located between the two guide posts 19 and is slidably connected to the guide posts 19. When the push plate 20 moves towards the lever base 17 to push the lever base 17, in order to reduce the friction between the lever base 17 and the push plate 20, multiple pulleys 18 are rotatably connected to the inner side of the lever base 17 away from the pivot 14. The end of the push plate 20 away from the hydraulic telescopic rod 21 is in contact with the multiple pulleys 18.
[0036] To facilitate the feeding of materials into the conveying pipe 6, a feeding assembly is provided between the upper end of the hollow base frame 1 and the conveying pipe 6. Specifically, the feeding assembly includes a feeding stand 7. The feeding stand 7 is fixed at the upper end of the hollow base frame 1 near the motor equipment 5. A funnel seat 8 is fixed on the inner side of the upper end of the feeding stand 7. A corrugated expansion tube 9 is fixedly connected to the lower end of the funnel seat 8. The end of the corrugated expansion tube 9 away from the funnel seat 8 extends to the inner side of the conveying pipe 6 and is fixed to the conveying pipe 6. Sealing rings 10 are fitted to the outer side between the corrugated expansion tube 9 and the funnel seat 8, and to the outer side between the corrugated expansion tube 9 and the conveying pipe 6.
[0037] All of the above electrical components are electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail here.
[0038] The spiral conveying pump provided by this utility model is used as follows: When it is necessary to convey materials to a higher place, the hydraulic telescopic rod 21 is activated to push out the push plate 20, so that the push plate 20 is in contact with multiple pulleys 18 and pushes the lever base frame 17 to rotate around the pivot 14. Then, while the lever base frame 17 is moving, the second guide rod 15 rotates synchronously around the pivot 14. By utilizing the rotational connection between the mounting guide column 16 and the first guide rod 12, and the rotational connection between the first guide rod 12 and the positioning support rod 11, the conveying bracket 4 is driven to rotate and lift around the bearing support shaft 3, thereby raising the discharge port of the conveying pipe 6 to a higher position, which facilitates the conveying of materials to a higher place. After the conveying bracket 4 is lifted, the corrugated telescopic pipe 9 is used to expand and contract synchronously, and the inner diameter of the corrugated telescopic pipe 9 is not affected, thus not affecting the material flow inside the corrugated telescopic pipe 9, so that the conveying bracket 4 can be fed normally after being lifted.
