Description

Technical Field

[0001] This utility model relates to an anti-clogging device, and more particularly to a device that can unclog a blocked chute, belonging to the technical field of chute anti-clogging equipment. Background Technology

[0002] A chute is a common transfer device that transports materials from one end to the other. Chutes typically require precise material discharge, hence the narrowing at the end, which makes them prone to blockage. Currently, when chutes become blocked, manual clearing is required. Workers use long poles to poke at the blockage, disrupting the stress structure. This process is time-consuming, labor-intensive, and inefficient, and also poses safety hazards for workers. Therefore, a device is needed to assist workers in efficiently clearing blockages in chutes, thereby reducing labor intensity and improving clearing efficiency. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide an anti-blocking device for material chutes, which can not only reduce the labor intensity of workers, but also improve the efficiency of clearing blockages in the chutes.

[0006] The above-mentioned anti-clogging device for a material discharge chute includes a material loosening section comprising a top material column, a guide cylinder, and a bottom limiting frame. A square hole is provided on the chute bottom plate. The guide cylinder is positioned on the bottom end face of the chute bottom plate, with its top opening aligning with the square hole on the chute bottom plate. The inner wall edge of the guide cylinder matches the inner wall outline of the square hole in the chute bottom plate. The bottom limiting frame is positioned at the bottom end of the guide cylinder's inner wall. The top material column is inserted into the guide cylinder, with its inner wall in close contact with the inner wall of the guide cylinder.

[0007] The aforementioned anti-clogging device for a material discharge chute includes a displacement component comprising a long rack, a slide rail, a slider, a vertical plate, a motor, and a gear. The long rack and slide rail are both disposed on the bottom end face of the chute bottom plate, with the length direction of the long rack parallel to the length direction of the slide rail. The length direction of the long rack is parallel to the length direction of the chute. The long rack is closer to the outer side of the chute than the slide rail. The slider is slidably disposed on the slide rail. The vertical plate is disposed on the bottom end face of the slider, and the motor is disposed on the side wall of the vertical plate. A gear is disposed on the output shaft of the motor, and the gear meshes with the teeth on the long rack for transmission.

[0008] The above-mentioned anti-blocking device for a material discharge chute includes a top material section comprising a horizontal plate, a hydraulic cylinder, and an electromagnet; the horizontal plate is positioned between the bottom ends of two vertical plates; the hydraulic cylinder is positioned on the top surface of the horizontal plate, and the axis of the hydraulic cylinder piston rod is parallel to the reverse line of the length of the top material column; the hydraulic cylinder is located directly below the top material column; and the electromagnet is positioned at the end of the hydraulic cylinder piston rod.

[0013] See Figure 1 and Figure 2This utility model includes a loosening section, a displacement section, and a top-loading section. The loosening section comprises multiple parts, evenly distributed along the length of the chute 13 on the bottom plate. Each loosening section can lift the material blocking the blockage, breaking the stress structure and ultimately clearing the blockage. The displacement section comprises two parts, symmetrically arranged on both sides of the bottom end face of the chute 13's bottom plate. Each displacement section can move the top-loading section below a designated loosening section, allowing the top-loading section to cooperate with the loosening section in lifting the blocked material. The top-loading section is positioned between the two displacement sections and directly below the loosening section.

[0014] The loosening section includes a top material column 1, a guide cylinder 2, and a bottom limiting frame 3; a square hole is provided on the bottom plate of the chute 13; the guide cylinder 2 is set on the bottom end face of the bottom plate of the chute 13, and the top opening of the guide cylinder 2 is aligned with the square hole on the bottom plate of the chute 13, which ensures that the top material column 1 can smoothly extend upward and retract downward; the inner wall edge contour of the guide cylinder 2 matches the inner wall contour of the square hole on the bottom plate of the chute 13; the bottom limiting frame 3 is set at the bottom end of the inner wall of the guide cylinder 2; the top material column 1... The column 1 is inserted into the guide cylinder 2, and the inner wall of the top material column 1 is in close contact with the inner wall of the guide cylinder 2; the top surface of the top material column 1 is flush with the top surface of the bottom plate of the chute 13, which ensures that the top material column 1 does not hinder the normal sliding of the material when the chute is discharging material normally; the bottom surface of the top material column 1 presses against the top surface of the bottom limit frame 3; a hole is provided in the center of the bottom surface of the top material column 1, and an iron block is fixedly installed in the hole. The function of the iron block is to ensure that the electromagnet on the hydraulic cylinder can pull the top material column 1 to retract smoothly.

[0015] The displacement component includes a long rack 4, a slide rail 5, a slider 6, a vertical plate 7, a motor 8, and a gear 9. The long rack 4 and slide rail 5 are both mounted on the bottom surface of the bottom plate of the chute 13, and the length direction of the long rack 4 is parallel to the length direction of the slide rail 5. The length direction of the long rack 4 is parallel to the length direction of the chute 13. The long rack 4 is closer to the outer side of the chute 13 than the slide rail 5. The slider 6 is slidably mounted on the slide rail 5. The slide rail 5 provides guidance for the slider 6. The vertical plate 7 is mounted on the bottom surface of the slider 6, and the motor 8 is mounted on the side wall of the vertical plate 7. A gear 9 is mounted on the output shaft of the motor 8, and the gear 9 meshes with the teeth on the long rack 4. The motor can drive the gear to rotate. When the rotating gear meshes with the stationary long rack 4, the gear will move forward along the length direction of the long rack 4, thereby driving the vertical plate to move forward synchronously. The vertical plates on both sides drive the middle horizontal plate 10 to move synchronously.

[0016] The top material section includes a horizontal plate 10, a hydraulic cylinder 11, and an electromagnet 12. The horizontal plate 10 is positioned between the bottom ends of two vertical plates 7. The hydraulic cylinder 11 is positioned on the top surface of the horizontal plate 10, and the axis of the piston rod of the hydraulic cylinder 11 is parallel to the reverse line of the length of the top material column 1. The hydraulic cylinder 11 is located directly below the top material column 1. The electromagnet 12 is positioned at the end of the piston rod of the hydraulic cylinder 11. When the hydraulic cylinder extends its piston rod, it can push the top material column 1 upward, thereby clearing the blocked material. When the electromagnet 12 is energized, it can attract the bottom end of the top material column, so that when the hydraulic cylinder retracts its piston rod, it can pull the top material column back to its initial position through the electromagnet.

[0017] Operating principle: When a blockage occurs in the chute, observe the position of the blockage end of the material in the chute, then control the motor to move the hydraulic cylinder 11 until the hydraulic cylinder 11 moves directly below the top support column at the end of the blockage. Then, start the electromagnet 12 and the hydraulic cylinder 11. The piston rod of the hydraulic cylinder extends and moves the top support column upward. During the upward movement of the top support column, the blocked material moves upward, thereby breaking the blockage structure. After the material in the chute is cleared, the piston rod of the hydraulic cylinder retracts. At this time, under the attraction of the electromagnet, the iron block at the bottom of the top support column is attracted downward until the top support column moves to the initial position. At this point, the chute blockage clearing operation is completed.
