Description

TECHNICAL FIELD

[0001] The present application relates to the field of material conveying equipment, in particular to a chute structure capable of preventing material accumulation. BACKGROUND

[0002] A ship loader is a large-scale bulk material machine used for loading ships at bulk cargo terminals. Generally, a ship loader is composed of a boom belt conveyor, a transition belt conveyor, an extendable chute, a tail car, a running device, a portal, a tower, a luffing device, a slewing device, and the like.

[0003] A conventional chute has a square structure. During loading, the ship loader inserts the chute into the ship cabin, and then the material at the top reaches the inlet of the chute through the conveyor belt and falls into the bottom of the ship cabin. When transporting materials such as iron powder, dust and environmental pollution can be reduced. During loading, the material is uniformly transported into the ship cabin as the ship loader moves. When transporting some blocky materials, the chute can be tilted to provide a buffer and reduce the impact of the material directly on the ship cabin.

[0004] When the material enters the ship cabin through the chute, a large amount of dust enters the ship cabin synchronously with the material, and thus needs to be improved. CONTENT OF THE INVENTION

[0005] In order to reduce dust entering the ship cabin, the present application provides a chute structure capable of preventing material accumulation.

[0006] The present application provides a chute structure capable of preventing material accumulation, which adopts the following technical solution:

[0007] The chute structure capable of preventing material accumulation comprises a first section of chute, which is a section of chute away from the ship cabin. An accumulated material separation assembly is arranged on the inner wall of the first section of chute. The accumulated material separation assembly comprises a plurality of accumulated material pieces, which are uniformly arranged along the axial direction of the first section of chute. When the material enters the ship cabin through the chute, part of the dust is intercepted by the accumulated material pieces.

[0008] By adopting the above technical solution, part of the dust can be effectively intercepted during the process of the material entering the ship cabin through the chute, thereby reducing the amount of dust entering the ship cabin. The design of the accumulated material pieces improves the impact resistance and wear resistance of the chute.

[0009] Preferably, the first section of chute has a cylindrical structure.

[0010] By adopting the above technical solution, the first section of chute is designed as a cylindrical structure, which can effectively prevent the accumulation and caking of the material inside the chute. The circular structure enables the material to flow more smoothly, reduces the risk of blockage caused by the shape of the edges, and improves the transportation efficiency. At the same time, this structure can also reduce the impact force of the material on the inner wall of the chute to some extent, prolonging the service life of the equipment.

[0011] Preferably, the material accumulation part comprises a connecting ring and a material blocking ring, the outer wall of the connecting ring is connected with the first section chute, the inner wall of the connecting ring is connected with the bottom wall of the material blocking ring, the connecting ring, the material blocking ring and the first section chute form a material accumulation area, and the opening of the material accumulation area is away from the cabin in the direction of the first section chute.

[0012] By adopting the above technical scheme, the material accumulation part comprises a connecting ring and a material blocking ring, the outer wall of the connecting ring is connected with the first section chute, the inner wall of the connecting ring is connected with the bottom wall of the material blocking ring, and a material accumulation area is formed, and the opening of the material accumulation area is away from the cabin in the direction of the first section chute. This design allows part of the dust to be intercepted by the material accumulation part when the material passes through the chute, thereby reducing the amount of dust entering the cabin and effectively reducing the impact of dust on the environment. At the same time, the design of the material accumulation area also avoids the direct impact of the material on the inner wall of the chute, reduces the wear of the chute, and prolongs the service life of the equipment.

[0013] Preferably, the connecting part between the connecting ring and the material blocking ring is provided with an arc-shaped wall.

[0014] By adopting the above technical scheme, the connecting part between the connecting ring and the material blocking ring is provided with an arc-shaped wall, which can effectively reduce the accumulation probability of the material at this position, prevent the sharp corner part from blocking or jamming the material, and further improve the smoothness and cleanliness of the inside of the chute.

[0015] Preferably, the bottom of the connecting ring is provided with a dust discharging assembly, the dust discharging assembly comprises a dust discharging ring and a driving part, the dust discharging ring is slidingly connected to the bottom of the connecting ring, the bottom of the connecting ring is provided with a connecting hole, the dust discharging ring is provided with a dust discharging hole, and the driving part is installed on the dust discharging ring to drive the dust discharging ring to rotate around the virtual center of the connecting ring to align the connecting hole and the dust discharging hole.

[0016] By adopting the above technical scheme, the dust discharging assembly can effectively discharge dust when needed. Specifically, when the driving part drives the dust discharging ring to rotate to align the connecting hole and the dust discharging hole, the dust in the material accumulation area can be smoothly discharged through the connected hole, thereby avoiding the problem of long-term accumulation of dust causing blockage or affecting the normal operation of the equipment. At the same time, this design can also ensure that the material accumulation area remains closed in the non-dust discharging state, preventing foreign matter from entering the inside of the chute, and further improving the cleanliness and service life of the equipment.

[0017] Preferably, the driving member comprises a driving rod, a driving block and a reset elastic rope, the side wall of the driving block is mounted on the inner wall of the dust discharging ring and protrudes the material blocking ring, a variable arc groove is formed in the driving block, the groove width of the variable arc groove gradually increases along the length direction, the driving rod is inserted at one end of the variable arc groove with small groove width, and the driving rod can drive the driving block to rotate to align the connecting hole and the dust discharging hole by being pressed down; one end of the reset elastic rope is connected with the dust discharging ring, and the other end is connected with the inner wall of the first section chute.

[0018] By adopting the above technical scheme, the design of the driving member enables the dust discharging ring to be accurately aligned with the connecting hole when needed, thereby effectively discharging the dust in the accumulated material area and avoiding damage to the equipment caused by long-term accumulation of dust. Meanwhile, the setting of the reset elastic rope ensures that the dust discharging ring can automatically return to the original position after completing the dust discharging action, thereby ensuring the continuity and stability of the equipment operation. In addition, the design of the variable arc groove on the driving block makes the driving rod pressing process more smooth, thereby improving the convenience of operation.

[0019] Preferably, the driving rod comprises a plurality of driving sub-rods, the bottom end diameter of each driving sub-rod is smaller than the top end diameter, and adjacent driving sub-rods are connected through threads.

The structural design that the bottom end diameter of each driving sub-rod is smaller than the top end diameter helps to reduce the driving resistance, ensures that the driving block can effectively drive the dust discharging ring to rotate when subjected to a smaller force, and realizes accurate alignment of the connecting hole and the dust discharging hole, thereby effectively discharging the accumulated dust, reducing the accumulation of dust inside the chute, and improving the equipment operation efficiency and service life.

[0021] Preferably, the maximum diameter of the driving sub-rod is greater than the maximum diameter of the variable arc groove.

[0022] By adopting the above technical scheme, when the maximum diameter of the driving sub-rod is greater than the maximum diameter of the variable arc groove, the driving sub-rod can be effectively prevented from being separated from the variable arc groove, thereby ensuring that the driving block will not be accidentally separated when subjected to material impact or vibration, and ensuring the stability and reliability of the dust discharging assembly.

DETAILED DESCRIPTION

[0033] The following will be described in detail in combination with the accompanying Figures 1-5 The present application will be further described in detail.

[0034] The present application discloses a chute structure for preventing material accumulation.

[0035] Embodiment 1

[0036] Reference Figure 1 and Figure 2The anti-material accumulation chute structure includes a first section chute 1, which is a section of chute away from the cabin. The first section chute 1 can adopt a cylindrical structure. The entire chute structure has three sections of chute, all of which adopt a cylindrical structure and are slidingly installed.

[0037] This can avoid the material accumulation problem caused by the square structure, and also help to improve the impact resistance of the chute. For example, the cylindrical structure can be made of stainless steel, which has good corrosion resistance and wear resistance; or high-strength alloy steel can be selected to enhance its strength and service life. In addition, the design of the cylindrical structure can also increase the surface roughness to increase the friction, which helps to prevent the material from sliding too fast and reduces the impact on the inner wall of the chute.

[0038] The inner wall of the first section chute 1 is provided with a material accumulation separation assembly 2, which includes a plurality of material accumulation pieces 21 uniformly arranged along the axis direction of the first section chute 1. When the material passes through the chute to the cabin, part of the dust is intercepted by the material accumulation pieces 21, achieving the effect of reducing the dust entering the cabin. The material accumulation pieces 21 can effectively intercept and store part of the dust, reducing the possibility of dust entering the cabin with the material.

[0039] Referring to Figure 1 and Figure 2 The material accumulation piece 21 includes a connecting ring 211 and a material blocking ring 212. The outer wall of the connecting ring 211 is fixed to the first section chute 1 by welding, and the inner wall of the connecting ring 211 is fixed to the bottom wall or side wall of the material blocking ring 212 by welding. The connecting ring 211, the material blocking ring 212 and the first section chute 1 form a material accumulation area 22, and the opening of the material accumulation area 22 is directed away from the cabin. The material of the connecting ring 211 and the material blocking ring 212 is the same as that of the first section chute 1. The thickness of the connecting ring 211 and the material blocking ring 212 can be adjusted according to actual needs, and the thickness is generally recommended to be between 5mm and 10mm, which can ensure sufficient strength without being too heavy.

[0040] The connecting part of the connecting ring 211 and the material blocking ring 212 is provided with an arc-shaped wall.

[0041] The implementation principle of the anti-material accumulation chute structure of the embodiment 1 is that part of the dust is intercepted by the material accumulation piece 21 when the material passes through the chute, reducing the amount of dust entering the cabin, thereby effectively reducing the impact of dust on the environment. At the same time, the design of the material accumulation area 22 also avoids the direct impact of the material on the inner wall of the chute, reducing the wear of the chute and improving the service life of the equipment.

[0042] Embodiment 2

[0043] The difference between this embodiment and embodiment 1 is that, in order to better manage and discharge the accumulated dust, referring to Figure 3and Figure 4 The bottom of the connecting ring 211 is provided with a dust discharging assembly 3, which comprises a dust discharging ring 31 and a driving member 32. The dust discharging ring 31 is slidingly connected to the bottom of the connecting ring 211, and the bottom of the connecting ring 211 is provided with a connecting hole 2111. The dust discharging ring 31 is provided with a dust discharging hole 311. The driving member 32 is installed on the dust discharging ring 31 and drives the dust discharging ring 31 to rotate around the virtual center of the connecting ring 211 so as to align the connecting hole 2111 and the dust discharging hole 311. The dust discharging ring 31 can be made of lightweight aluminum alloy material, which not only reduces the weight but also ensures sufficient strength and rigidity.

[0044] When the driving member 32 drives the dust discharging ring 31 to rotate so as to align the connecting hole 2111 and the dust discharging hole 311, the dust in the accumulated material area 22 can be smoothly discharged through the connected hole. At the same time, this design can also ensure that the accumulated material area 22 remains closed in the non-dust discharging state, preventing foreign matter from entering the inside of the lapping cylinder, further improving the cleanliness and service life of the equipment.

[0045] Referring to Figure 4 and Figure 5 The driving member 32 comprises a driving rod 321, a driving block 322 and a reset elastic cord 323. The side wall of the driving block 322 is integrally formed on the inner wall of the dust discharging ring 31 and protrudes to block the material ring 212. The driving blocks 322 of the plurality of connecting rings 211 are on the same straight line.

[0046] The driving block 322 is provided with a variable arc groove 3221. The virtual center of the variable arc groove 3221 is coaxial with the virtual center of the dust discharging ring 31. The groove width of the variable arc groove 3221 gradually increases along the length direction. The driving rod 321 is inserted at one end of the variable arc groove 3221 with small groove width. The driving rod 321 can be pressed downward to drive the dust discharging ring 31 to rotate so as to align the connecting hole 2111 and the dust discharging hole 311.

[0047] The driving rod 321 comprises a plurality of driving sub-rods 3211. The horizontal cross section of each driving sub-rod 3211 is circular. The bottom end diameter of each driving sub-rod 3211 is smaller than the top end diameter, that is, the horizontal cross section of the driving sub-rod 3211 gradually increases from bottom to top. Adjacent driving sub-rods 3211 are connected by threads. This segmented design facilitates disassembly and replacement, and also facilitates adjustment of the total length of the driving rod 321 to adapt to different working conditions. In order to ensure the entire dust discharging operation, the bottom of the first lapping cylinder 1 is provided with a block that limits the change of the axis of the driving rod 321. The bottom of the driving rod 321 is provided with a shaft that can penetrate the block. In other embodiments, the driving member 32 can be provided with a plurality of driving members 32 arranged along the circumference of the dust discharging ring 31 to ensure the smoothness of the rotation of the dust discharging ring 31.

[0048] In particular, the maximum diameter of the driving sub-rod 3211 is greater than the maximum diameter of the variable arc groove 3221. When the maximum diameter of the driving sub-rod 3211 is greater than the maximum diameter of the variable arc groove 3221, the driving sub-rod 3211 can be effectively prevented from disengaging from the variable arc groove 3221, ensuring that the driving block 322 will not accidentally fall off when subjected to material impact or vibration, thereby ensuring the stability and reliability of the dust discharging assembly 3.

[0049] One end of the reset elastic cord 323 is connected to the dust discharging ring 31, and the other end is connected to the inner wall of the first section of the chute 1. This design makes the dust discharging process more automated and reliable, reduces the need for manual intervention, and improves work efficiency. The reset elastic cord 323 can be made of spring steel wire, which has good elastic recovery ability, ensuring that the dust discharging ring 31 can automatically reset after each dust discharging.

[0050] The implementation principle of the material accumulation prevention chute structure according to an embodiment of the present application is as follows: when it is necessary to remove dust in the material accumulation area 22, the driving rod 321 is pressed. Since the inner diameter of the driving sub-rod 3211 changes in the variable arc groove 3221, in order to allow the driving sub-rod 3211 to smoothly move in the variable arc groove 3221, the driving block 322 moves to drive the dust discharging ring 31 to rotate. When the driving member 32 drives the dust discharging ring 31 to rotate to align the connecting hole 2111 and the dust discharging hole 311, the dust in the material accumulation area 22 can be smoothly discharged through the connected hole. After the dust is removed, the driving rod 321 is released. At this time, under the action of the reset elastic cord 323, the dust discharging ring 31 drives the driving block 322 to reset, the width of the driving groove at the axis position of the driving rod 321 changes, thereby resetting the height of the driving rod 321.

[0051] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Therefore, equivalent changes made in accordance with the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
