Description

A vibratory arch-breaking device for port hoppers Technical Field

[0001] This utility model relates to a component structure used in a port unloading hopper, and more particularly to a vibratory arch-breaking device for a port hopper. Background Technology

[0002] During the unloading process of cargo in ports, unloading hoppers are usually used as loading and transfer devices between ships and shore equipment and vehicles. The unloading hopper is usually equipped with an inverted frustum-shaped structure made of welded steel plates with a certain volume. The cargo is discharged into the hopper from the top through the unloading equipment and flows into the receiving device such as the conveyor belt or truck bed through the rectangular opening at the bottom. In actual application, it has been found that when materials with low moisture content and large particle size pass through the hopper, "bridging" (arch blockage) problems will form due to the moisture, stickiness and high friction between particles of the cargo, which will affect normal production operations.

[0003] To effectively control cargo flow and speed between dockside unloading equipment, and to prevent cargo bridging (arching blockage) within the hopper, shock-absorbing caps are typically installed at the top of the hopper, and arch-breaking devices are installed below the hopper wall. These devices break up the arched structure of the material, promote material flow, prevent intermittent blockages, thereby improving unloading efficiency and ensuring the continuity of port loading and unloading operations. However, existing arch-breaking devices are complex in structure, have poor adaptability, are difficult to effectively break up arches for different materials, and can easily interfere with material feeding, affecting the overall operating efficiency of the equipment. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a vibratory arch-breaking device for port hoppers that can effectively break up arched blockages formed by materials inside the hopper without hindering the flow of materials.

[0005] To solve the above-mentioned technical problems, the vibratory arch-breaking device for port hoppers of this utility model includes a vibratory plate tightly attached to the inner wall of the hopper and a vibratory pump fixed to the outer wall of the hopper. The upper part of the vibratory plate is limited by a limiting groove, and a through hole is opened in the middle of the vibratory plate. The vibratory pump passes through the through hole, connects to the vibratory plate, and is fixed on the hopper.

[0006] The upper part of the hopper opening is provided with a shock-absorbing cap, which is shaped like a frustum.

[0007] The limiting groove is formed by the space between the fixing pin welded to the inner wall of the hopper and the inner wall.

[0008] The lower end of the vibration pump is provided with a vibration pump base, which is fixed to the vibration plate by a steel sleeve welded to its end.

[0009] Each of the aforementioned vibrating plates has a fixing pin on only one side.

[0010] The outer wall of the hopper is provided with a lug plate for connecting a safety rope. One end of the safety rope is connected to the lug plate, and the other end is connected to the vibration pump.

[0011] Advantages of this utility model:

[0012] When the hopper becomes clogged due to material bridging, this device uses a vibrating pump to drive a vibrating plate, generating mechanical vibration or impact force. Combined with a shock-absorbing cap at the hopper opening, this effectively transfers the vibrational energy to the clogged area, overcoming the arched structure formed by static friction between materials and achieving rapid arch breaking. The device has a compact structure; the vibrating plate is attached to the inner wall of the hopper, and the vibrating pump is fixed to the outer wall, without interfering with the normal operation of the hopper. Vibrating plates can be flexibly added as needed, making it suitable for different types of hoppers and exhibiting good versatility. The shock-absorbing cap effectively buffers impact force, reduces structural stress, and extends the equipment's service life. Simultaneously, a safety rope prevents the vibrating pump from falling off, further enhancing the safety of the system operation. Attached Figure Description
