Description

Technical Field

[0001] This utility model relates to the field of unloading machine technology, and in particular to a through-duct type multi-blade unloading machine. Background Technology

[0002] The function of a discharge machine is to help materials in a hopper discharge more efficiently. Because the outlet size of the hopper is relatively small, a conical structure is typically designed to guide the material inside the hopper towards the outlet. However, this traditional conical structure often leads to center flow or blockage, affecting normal operation. Summary of the Invention

[0003] The purpose of this utility model is to provide a through-duct type multi-blade unloader that can discharge materials in the hopper evenly and orderly, avoid the occurrence of central flow or material blockage, and improve production stability.

[0004] This utility model provides a through-duct type multi-blade unloading machine, including:

[0005] The hopper is shaped like a rotating body, and a discharge port is provided at the center of the bottom plate of the hopper;

[0006] A passageway is arranged horizontally inside the silo, and both ends of the passageway are fixedly connected to the side wall of the silo. The passageway is located directly above the discharge port.

[0007] The device includes a drive unit and a discharge scraper. The discharge scraper comprises multiple arc-shaped blades arranged in a circular pattern. The discharge scraper is located inside the hopper and close to the bottom plate of the hopper. The drive unit drives the discharge scraper to rotate. The rotation center of the discharge scraper coincides with the center of the discharge port.

[0008] Preferably, the thickness of the arc-shaped single blade varies in a stepped manner, with the thickness being greater on the side of the arc-shaped single blade closer to the discharge port.

[0009] Preferably, the diameter of the discharge port does not exceed the width of the passageway.

[0010] Preferably, the difference between the diameter of the discharge port and the width of the corridor is not less than the distance between the corridor and the bottom surface of the silo.

[0011] Preferably, the driving device is located inside the corridor, and the driving end of the driving device penetrates downward through the bottom plate of the corridor and connects to the unloading scraper.

[0012] Preferably, the bottom surface of the hopper is a plane, and the lower surface of the unloading scraper is in contact with the bottom surface of the hopper.

[0013] Preferably, the bottom surface of the silo is a conical surface, and the angle between the bottom surface of the silo and the horizontal plane is less than 5 degrees.

[0014] Preferably, the sidewall of the silo is conical.

[0015] Preferably, the sidewall of the silo is columnar.

[0016] Preferably, the top surface of the corridor is an arched structure.

[0017] The technical solution of this utility model uses a drive device to drive the unloading scraper, and the arc-shaped single blade rotates to discharge the material in the hopper. The passage is located directly above the discharge port, which can prevent the material from leaking out under the action of gravity. At the same time, the passage reduces the falling efficiency of the material, reduces the load on the unloading scraper, and discharges the material in the discharge hopper stably and evenly, avoiding the occurrence of phenomena such as center flow or material blockage.

[0028] Combination Figures 1 to 4 As shown, the present invention provides a through-duct type multi-blade unloading machine including a hopper 1, a through-duct 2, a drive device 3, and an unloading scraper 4.

[0029] Combination Figures 1 to 4 As shown, the hopper 1 has a cone-shaped rotating body shape, the bottom surface of the hopper 1 is flat, and the discharge port 5 is provided at the center of the bottom surface.

[0030] The passageway 2 is horizontally arranged inside the silo 1, and both ends of the passageway 2 are fixedly connected to the side walls of the silo 1. The passageway 2 is located directly above the discharge port 5, and the diameter of the discharge port 5 must not exceed the width of the passageway 2. There is generally a certain size difference between the two, and the size difference between the diameter of the discharge port 5 and the width of the passageway 2 is generally not less than the distance between the bottom surface of the passageway 2 and the silo 1 to ensure the sealing effect in a static state. The top surface of the passageway 2 adopts an arched structure, with a higher position in the middle and lower positions on both sides to prevent materials from accumulating on top of the passageway 2.

[0031] The unloading scraper 4 is composed of multiple circularly distributed arc-shaped single blades 41; the unloading scraper 4 is located inside the hopper 1 and close to the bottom plate of the hopper 1, and the lower surface of the unloading scraper 4 is in contact with the bottom surface of the hopper 1; the thickness of the arc-shaped single blades 41 varies in a stepped manner, and the thickness of the arc-shaped single blades 41 is greater on the side closer to the discharge port 5, and the position of the thickness change is close to the outer edge of the corridor 2.

[0032] The drive device 3 is located inside the corridor 2. The drive device 3 generally includes a drive motor and a motor reducer. The drive end of the drive device 3 refers to the output shaft. The drive end of the drive device 3 passes downward through the bottom plate of the corridor 2 and connects to the unloading scraper 4. The drive device 3 drives the unloading scraper 4 to rotate. The rotation center of the unloading scraper 4, the axisymmetric center of the arc-shaped single blade 41, and the center of the discharge port 5 coincide.

[0033] Working process: The material is naturally piled in the silo 1. The material falls from both sides of the corridor 2 and accumulates on the bottom plate under the division of the corridor 2.

[0034] When the drive unit 3 is not started, the material will not enter the discharge port 5 because the passageway 2 completely covers the top of the discharge port 5.

[0035] When the drive device 3 is started, the drive device 3 will drive the unloading scraper 4 to rotate. The arc-shaped feature on the arc-shaped single blade 41 will guide the material to move inward during the process of pushing the material, so as to drive the material on the bottom plate of the hopper 1 to gather towards the center. Finally, the material is discharged from the hopper 1 through the discharge port 5.

[0036] In this embodiment, the discharge scraper 4 is driven by the drive device 3, and the arc-shaped single blade 41 rotates to discharge the material in the hopper 1. The passageway 2 is located directly above the discharge port 5, which can prevent the material from leaking out under the action of gravity. At the same time, the passageway 2 will reduce the falling efficiency of the material, reduce the load on the discharge scraper 4, and discharge the material in the discharge hopper 1 stably and evenly, avoiding the occurrence of phenomena such as central flow or material blockage.

[0037] In this embodiment, when the arc-shaped single blade 41 passes directly below the corridor 2, the corridor 2's obstruction slows down the speed at which material enters the gap between the arc-shaped single blades 41, thereby reducing the load on the arc-shaped single blades 41. Since the gap between the arc-shaped single blades 41 is fan-shaped and gradually increases from the inside to the outside, the efficiency of material entering the gap exceeds the efficiency of material discharge. The obstruction of the corridor 2 slows down the speed at which material enters the gap, which helps the outer material to be discharged, and avoids the inner material replenishment efficiency covering the material discharge efficiency, thus making it difficult for the outer material to be discharged.

[0038] In this embodiment, the conical structure is not used to guide the material into the discharge port 5. With the volume of the silo 1 remaining unchanged, the overall height of the silo 1 can be reduced.

[0039] In some embodiments, combined with Figure 4 As shown, the sidewall of the silo 1 is columnar. With the same maximum outer contour, the columnar silo 1 will have a larger volume. The bottom surface of the silo 1 is conical, which makes the process of material entering the discharge port 5 smoother. However, it is necessary to avoid the bottom surface of the silo 1 being too inclined, which would cause the material to fall naturally into the discharge port 5 under the action of the inclined surface, making it impossible to stop the material from being discharged from the discharge port 5 into the silo 1. Generally, the angle between the bottom surface of the silo 1 and the horizontal plane is controlled within the range of less than 5 degrees.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
