Description

Technical Field

[0001] This utility model relates to the field of conveying machinery technology, and in particular to a non-powered interval feeding device for a Z-type elevator. Background Technology

[0002] Z-type elevators are widely used for the vertical conveying of granular or powdery materials. They use a sprocket-driven conveyor chain to move the buckets from a low position to a high position for receiving material. Traditional feeding devices often use independent power sources (such as motors) to drive the feeding mechanism, but this results in high energy consumption, requires an additional power system, and the feeding rhythm is easily out of sync with the movement of the elevator buckets, leading to material spillage or uneven filling. Furthermore, separate power sources complicate the elevator structure and increase maintenance costs. Therefore, there is an urgent need for a device that can operate synchronously with the elevator, requires no independent power, and provides precise feeding. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a Z-type elevator non-powered interval feeding device, which achieves strict synchronization with the conveyor chain through mechanical linkage, eliminates power redundancy, and ensures that the material falls accurately into the moving hopper.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a Z-type elevator with unpowered interval feeding device. The elevator includes a low-level horizontal section, an lifting section, and a high-level horizontal section. A conveyor chain is provided inside the elevator, and multiple hoppers are arranged along the conveyor chain. The elevator is used to convey the hoppers along the conveying direction. A hopper is provided on one side of the low-level horizontal section for storing materials. A discharge port is provided at the lower end of the hopper, and a feeding device is connected to the discharge port. The feeding device includes a feeding shell and a rotating discharge cylinder rotatably mounted on the feeding shell. The rotating discharge cylinder has multiple discharge ports spaced apart along its circumference. The feeding device also has a transmission component, which is connected to the conveyor chain of the elevator, so that the rotating discharge cylinder of the feeding device is driven by the conveyor chain to rotate synchronously. This ensures that the discharge position of the rotating discharge cylinder matches the movement position of the hopper in the low-level horizontal section in real time, so that the discharge from a single discharge port of the rotating discharge cylinder falls into a hopper passing below it.

[0005] Specifically, the rotating feed cylinder is rotatably mounted on the feed housing via a support shaft.

[0006] Specifically, the feeding device also includes a spiral feeding channel, one end of which extends into the discharge port of the hopper, and the other end is sealed and rotatably connected to the rotating feed cylinder.

[0007] Specifically, the conveyor chain includes two chains arranged opposite each other; the transmission component includes a first transmission sprocket and a second transmission sprocket, the first transmission sprocket being located outside the support shaft and meshing with one of the chains of the conveyor chain; the second transmission sprocket being located outside the spiral feeding channel and meshing with the other chain of the conveyor chain.

[0008] Specifically, the spacing between the discharge ports of the rotating discharge cylinder is matched with the spacing between the hoppers in the lower horizontal section.

[0009] Specifically, the tooth pitch of the first transmission sprocket corresponds to the pitch of the chain.

[0010] Specifically, the spiral feeding channel is equipped with an internal propeller.

[0011] Specifically, a sealing plate is provided at the connection between the hopper outlet and the spiral feeding channel, and the sealing plate is used for dust prevention and sealing.

[0012] Specifically, the hopper is also equipped with support legs on the side away from the elevator.

[0013] Specifically, the end of the elevator is provided with an elevator power mechanism for driving the conveyor chain to move.

[0014] Based on the above technical solution, the beneficial effects of this utility model are:

[0015] 1. This utility model utilizes a structure where the conveyor chain directly drives the transmission sprocket, achieving precise synchronization between the rotating discharge cylinder and the elevator buckets. This eliminates the need for an independent power source, effectively reducing equipment energy consumption and maintenance costs. The circumferential spacing between the discharge ports of the rotating discharge cylinder and the installation spacing of the elevator buckets are precisely matched. Combined with the correspondence between the transmission sprocket tooth pitch and the conveyor chain pitch, this ensures that a corresponding bucket always moves directly beneath each discharge port to receive material during unloading. This effectively solves the material spillage problem caused by timing deviations in traditional feeding devices, significantly improving filling accuracy.

[0016] 2. The sealed connection between the spiral feeding channel and the hopper outlet in this utility model, along with the sealing plate located at the hopper outlet, ensures the continuity of material conveying and effectively suppresses dust dispersion. The overall structure fully utilizes the existing power of the elevator, achieving self-synchronization of the feeding action through mechanical linkage, simplifying the complexity of the control system. The addition of support legs further enhances the load-bearing stability of the hopper, ensuring the reliability and environmental adaptability of the feeding device during long-term operation.

[0024] like Figure 1-2 As shown in the figure, this application provides a Z-type elevator non-powered interval feeding device, including a Z-type elevator 2, a hopper 7 and a feeding device 6. The feeding device 6 includes a feeding shell, a rotating discharge cylinder 64 rotatably mounted on the feeding shell, a transmission component and a screw feeding channel 61.

[0025] The elevator 2 includes a low-level horizontal section, a lifting section, and a high-level horizontal section. A conveyor chain 3 is installed inside the elevator 2; specifically, the conveyor chain 3 includes two opposing chains. Multiple hoppers 4 are arranged along the conveyor chain 3, and the elevator 2 is used to convey the hoppers 4 along the conveying direction. Furthermore, an elevator power mechanism 1 is provided at the end of the elevator 2 to drive the conveyor chain 3; an electric unloading device 5 is provided in the high-level horizontal section of the elevator 2 for unloading material from the hoppers 4.

[0026] The Z-type elevator in this invention can be any existing Z-type elevator in the field.

[0027] Furthermore, a hopper 7 is provided on one side of the low horizontal section of the elevator 2, which is used to store materials. The lower discharge port of the hopper 7 is connected to a feeding device 6. Preferably, the rotating feeding cylinder 64 is rotatably mounted on the feeding housing via a support shaft 65. A bearing 66 is provided on the outer side of the feeding housing to fix the support shaft 65. The rotating feeding cylinder 64 is rotatably mounted on the feeding housing via the support shaft 35. Specifically, the rotating feeding cylinder 64 is sealed and rotatably connected to the screw feeding channel 61. Furthermore, the screw feeding channel 61 is provided with an inner propeller for conveying materials to the rotating feeding cylinder 64.

[0028] A sealing plate 71 is provided at the connection between the lower discharge port of the hopper 7 and the screw feeding channel 61. The sealing plate 71 is used for dust prevention and sealing. Preferably, an annular limiting plate is provided at the discharge port, with an annular groove on the inner side of the annular limiting plate. An annular sealing plate is provided on the outer side of the screw feeding channel 61, with the free end of the annular sealing plate extending into the annular groove. A support leg 72 is also provided on the side of the hopper 7 away from the elevator 2, which further enhances the load-bearing stability of the hopper 7, ensuring the reliability and environmental adaptability of the feeding device during long-term operation. Together with the sealing plate 71 at the discharge port of the hopper, it not only ensures the continuity of material conveying but also effectively suppresses dust dispersion.

[0029] The rotating feeding cylinder 64 has multiple feeding ports spaced apart along its circumference; the feeding device 6 also has a transmission component, which includes a first transmission sprocket 62 and a second transmission sprocket 63. The first transmission sprocket 62 is located outside the support shaft and meshes with one of the chains of the conveyor chain 3; the second transmission sprocket 63 is located outside the spiral feeding channel 61 and meshes with the other chain of the conveyor chain 3. Specifically, the tooth pitch of the first transmission sprocket 62 and the second transmission sprocket 63 corresponds to the pitch of the chain.

[0030] Because the transmission components are connected to the conveyor chain 3 of the elevator 2, the rotating discharge cylinder 64 of the feeding device 6 is driven by the conveyor chain 3 to rotate synchronously. This ensures that the discharge position of the rotating discharge cylinder 64 matches the movement position of the hopper 4 in the low horizontal section in real time, so that the discharge from a single discharge port of the rotating discharge cylinder 64 falls into a hopper 4 passing below it. Specifically, the spacing between the discharge ports of the rotating discharge cylinder 64 matches the spacing between the hoppers 4 in the low horizontal section.

[0031] The feeding device structure of this utility model makes full use of the original power of the elevator and realizes the self-synchronization of the feeding action through mechanical linkage, which simplifies the complexity of the control system.

[0032] During the operation of the rotating feed cylinder, such as Figure 3 As shown, since the rotating feeding cylinder 64 is divided into multiple feeding ports, the unloading process of the feeding ports when the rotating feeding cylinder 64 rotates counterclockwise corresponds exactly to the movement of the horizontally moving hopper 4 to the right. That is, when the rotating feeding cylinder 64 starts unloading, the material falls into the hopper 4. Moreover, the movement of the hopper 4 with the conveyor chain 3 corresponds exactly to the rotation of the rotating feeding cylinder 64. The unloading process of a single feeding port of the rotating feeding cylinder 64 corresponds exactly to a certain hopper 4. The material at the beginning and end of the unloading process falls into the corresponding hopper 4. This is repeated to achieve intermittent feeding with the material falling into the hopper 4. The whole process does not compress the material, maintaining the original physical state and particle size of the material; it also avoids the occurrence of material spillage, effectively solving the material spillage problem caused by timing deviation in traditional feeding devices, and significantly improving filling accuracy.

[0033] It should be noted that the above embodiments are only used to illustrate the present utility model, but the present utility model is not limited to the above embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
