[0002] Screw conveyors are used in many production fields. They can transport materials from low to high places. However, some problems often occur during use. If the material itself has a certain degree of stickiness, it will accumulate and cause blockage when it reaches the discharge port. This will affect production efficiency and increase equipment costs. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a spiral feeding elevator with anti-blocking function at the discharge port.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A screw feeder elevator with anti-clogging function at the discharge port includes a support frame. A controller is installed on the front end of the support frame. The support frame is fitted to the feeder elevator. A discharge pipe is provided at the discharge end of the feeder elevator. A support plate is provided on one outer wall of the discharge pipe. A hydraulic cylinder is installed on the support plate. A support fixing seat is installed at the output end of the hydraulic cylinder. A servo motor is installed in the support fixing seat. A connecting rotating shaft is installed at the front end of the servo motor. The connecting rotating shaft is driven by the servo motor. The front end of the connecting rotating shaft is connected to an inclined pusher plate, which is installed inside the discharge pipe.
[0005] In addition, a preferred structure is that a sliding groove is provided on the outer wall of one side of the feed tube, and the connecting rotating shaft slides up and down in the sliding groove.
[0006] In addition, a preferred structure is that a corrugated rubber sealing ring is provided on the inner side of the connection between the sliding groove and the outer wall of the feed pipe.
[0007] Furthermore, in a preferred configuration, the controller controls the hydraulic cylinder and servo motor via electrical signals.
[0008] In addition, a preferred structure is that multiple scrapers are evenly arranged at both ends of the inclined push plate.
[0009] In addition, a preferred structure is that a smooth coating is provided on the inner wall of the feed tube, and the smooth coating is made of polytetrafluoroethylene material that is evenly applied and covered.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Reference Figure 1-5 A spiral feeding elevator with anti-blocking function at the discharge port includes a support frame 1. A controller 11 is provided on the front end of the support frame 1. The support frame 1 is installed in close contact with the feeding elevator 3. A discharge pipe 31 is provided at the discharge end of the feeding elevator 3. A support plate 32 is provided on the outer wall of one side of the discharge pipe 31. A hydraulic cylinder 4 is installed on the support plate 32. A support fixing seat 41 is installed at the output end of the hydraulic cylinder 4. A servo motor 5 is installed in the support fixing seat 41. A connecting rotating shaft 51 is installed at the front end of the servo motor 5. The connecting rotating shaft 51 is driven by the servo motor 5. The front end of the connecting rotating shaft 51 is connected and installed with an inclined pusher plate 52. The inclined pusher plate 52 is installed in the discharge pipe 31.
[0015] The material feeding pipe 31 has a sliding groove 6 on one side of its outer wall. The connecting rotating shaft 51 slides up and down in the sliding groove 6. The hydraulic cylinder 4 is connected to the support fixing seat 41. The support fixing seat 41 is equipped with a servo motor 5. The servo motor 5 is driven by the connecting rotating shaft 51, so that the hydraulic cylinder 4 drives the connecting rotating shaft 51 to slide up and down.
[0016] Meanwhile, a corrugated rubber sealing ring 61 is provided on the inner side of the connection between the sliding groove 6 and the outer wall of the feed pipe 31. The corrugated rubber sealing ring 61 is provided to increase the sealing of the connection when the connecting rotating shaft 51 slides up and down in the sliding groove 6.
[0017] Furthermore, the controller 11 controls the hydraulic cylinder 4 and the servo motor 5 via electrical signals, and the controller 11 can control different drive machines separately and asynchronously.
[0018] The inclined pusher plate 52 has multiple scrapers evenly arranged at both ends. The front end of the inclined pusher plate 52 is set as a cone, which can be easily inserted into the blocked material. When the scrapers at both ends are rotated to a horizontal state, the contact area between the inclined pusher plate 52 and the material can be increased, which can facilitate the unblocking of the discharge pipe 31.
[0019] Meanwhile, a smooth coating is provided on the inner wall of the feeding pipe 31. The smooth coating is made of polytetrafluoroethylene material and is evenly applied. The smooth coating can reduce the contact friction between the material and the inner wall of the feeding pipe 31, making it easier for the material to be discharged.
[0020] In this embodiment, the support frame 1 is first placed stably, and then the material to be transported is placed inside the support frame 1. Then, the feeding elevator 3 starts to transport the material to the discharge port through the internal structure. When a large amount of material accumulates at the discharge port, a discharge pipe 31 is set at the discharge port. A hydraulic cylinder 4 is installed on the support plate 32 set on the outside of the discharge pipe 31. A servo motor 5 is installed in the support fixing seat 41 at the output end of the hydraulic cylinder 4. A connecting rotating shaft 51 is installed at the front end of the servo motor 5. When the material is blocked, the controller 11 controls the servo motor 5 through an electrical signal. The servo motor 5 drives the connecting rotating shaft 51 to drive the inclined push plate 52 to rotate from the vertical state to the horizontal state. The controller 11 controls the hydraulic cylinder 4 through an electrical signal. The hydraulic cylinder 4 drives the servo motor 5 and the connecting rotating shaft 51 to slide up and down in the sliding groove 6. The inclined push plate 52 drives the blocked material above to move down and out of the discharge pipe 31.
[0021] In this invention, the servo motor 5 drives the connecting rotating shaft 51 to rotate the inclined pusher plate 52 from a vertical state to a horizontal state. The hydraulic cylinder 4 drives the connecting rotating shaft 51 to slide up and down, so that the inclined pusher plate 52 can clear the blocked material. This can improve the anti-blocking function of the feeding elevator 3 and improve the material transportation and production efficiency.
[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
