[0002] During the unloading process of cargo at ports, a hopper is usually used as a loading and transfer device between ships and shore-based equipment and vehicles. The hopper is usually a chamfered pyramid-shaped structure with a certain volume and made of welded steel plates. The cargo is discharged from the upper part into the hopper through the unloading equipment and flows through the lower rectangular opening to the receiving conveyor or car compartment. In order to reasonably control the flow of cargo and the speed between the dock unloading equipment, and prevent the excessive flow of cargo from causing abnormal damage or malfunction of the receiving device below, an opening and closing device is usually installed at the lower rectangular opening to achieve control of the cargo transfer speed.

[0003] During actual application, it was found that when materials with low moisture content and large particle size pass through the bucket mouth opening and closing device, the opening and closing device will not cause abnormal operation. However, materials with high moisture content and small particle size that are easy to flow are difficult to be effectively closed when controlled by the bucket mouth opening and closing device, which can easily cause the goods to be spilled and dripped at the bucket mouth, affecting normal production operations.

[0004] Therefore, in order to solve the above problems, a leak-proof arc-shaped opening and closing device for a port hopper is proposed. Utility Model Content

[0005] In order to make up for the shortcomings of the existing technology and solve the problem that cargoes with high water content and small particle size that are easy to flow are difficult to be effectively closed through the hopper opening and closing device, which easily causes cargo to be spilled and dripped at the hopper mouth and affects normal production operations, a leak-proof arc opening and closing device for port hoppers is proposed.

[0006] The technical solution adopted by the present invention to solve its technical problems is: the utility model is a leak-proof arc-shaped opening and closing device for a port hopper, comprising a hopper mouth, connecting clamps are installed on both sides of the hopper mouth, a first closing plate is installed on one side of the connecting clamp, a second closing plate is provided on the side of the connecting clamp away from the first closing plate, the first closing plate and the second closing plate are staggeredly connected inside the connecting clamp, a fixed shaft is connected through the inside of the connecting clamp, the surface of the fixed shaft is sleeved with a first steel sleeve, the surface of the fixed shaft is also provided with a spacer, the spacer is arranged at the bottom of the first steel sleeve, the surface of the fixed shaft is also sleeved with a second steel sleeve, and the surface of the connecting clamp is provided with a gear.

[0007] Preferably, a first parallel closing plate is movably connected below the hopper mouth, and a second parallel closing plate is also movably connected below the hopper mouth, and the first parallel closing plate is installed above the second parallel closing plate.

[0008] Preferably, a hinge plate is provided at the bottom of the first parallel closed plate, and the hinge plate is also installed at the bottom of the second parallel closed plate. An electric push rod is connected to the surface of the hinge plate.

[0009] Preferably, two pairs of parallel openings are provided in the middle of the hopper mouth, and the first closing plate and the second closing plate are fixed on the fixed shaft through a first steel sleeve and a second steel sleeve respectively.

[0010] Preferably, the first parallel closing plate and the second parallel closing plate form an arc angle of 0-50° with the unloading direction of the hopper mouth, and a buffer space is provided between the first parallel closing plate and the second parallel closing plate to facilitate the staggered closure of the first parallel closing plate and the second parallel closing plate when engaged and closed.

[0011] Preferably, the overlapping areas after the first closing plate, the second closing plate, the first parallel closing plate and the second parallel closing plate are meshed are arranged with meshing tooth plates in parallel and staggered from top to bottom. The number of the meshing tooth plates is several, and the distance between two meshing tooth plates is 10-20 mm.

[0012] Beneficial effects of the utility model:

[0013] The utility model provides a leak-proof arc-shaped opening and closing device for a port hopper, which is provided with a first closing plate with a rotating opening and closing function, a second closing plate and a first parallel side arc-shaped closing plate matched therewith, and a plurality of tooth plates that are provided and mesh with each other. Therefore, during the material unloading process, the size of the hopper opening can be controlled by adjusting the telescopic distance of an electric push rod, thereby controlling the material conveying amount. After the closing plate and the meshing plate are closed in place, the material is effectively sealed inside the hopper, effectively avoiding the inability to effectively close the material at the hopper opening due to individual materials with larger particle sizes and the occurrence of dripping of fluid goods after closing, thereby playing a leak-proof role.

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Specific examples are given below.

[0023] See also Figures 1-4 The utility model provides a leak-proof arc-shaped opening and closing device for a port hopper, comprising a hopper mouth 1, connecting clamps 14 are installed on both sides of the hopper mouth 1, a first closing plate 2 is installed on one side of the connecting clamp 14, a second closing plate 3 is provided on the side of the connecting clamp 14 away from the first closing plate 2, the first closing plate 2 and the second closing plate 3 are staggeredly connected inside the connecting clamp 14, a fixed shaft 7 is connected through the inside of the connecting clamp 14, the surface of the fixed shaft 7 is sleeved with a first steel sleeve 8, the surface of the fixed shaft 7 is further provided with a spacer 10, the spacer 10 is arranged at the bottom of the first steel sleeve 8, the surface of the fixed shaft 7 is further sleeved with a second steel sleeve 9, and a gear 11 is provided on the surface of the connecting clamp 14.

[0024] In this embodiment, closing is achieved by adding a synchronously meshing gear 11, and the first parallel closing plate 4 and the second parallel closing plate 5 are welded and fixed to the first closing plate 2 and the second closing plate 3. The rotation opening and closing of the first closing plate 2 and the second closing plate 3 are utilized to close the closing plate. Space is left between the first parallel closing plate 4 and the second parallel closing plate 5 to facilitate staggered closure during meshing and closing. The first parallel closing plate 4 and the second parallel closing plate 5 are arc-shaped, and space is also left between them and the hopper mouth 1. After the first closing plate 2, the second closing plate 3, the first parallel closing plate 4, the second parallel closing plate 5 and the meshing gear plate 6 are closed in place, the unloaded material can be effectively closed and will not be unable to be closed or lost due to the large particle size or easy flow of the cargo.

[0025] See also Figure 1-4A first parallel closing plate 4 is movably connected to the bottom of the hopper mouth 1 , and a second parallel closing plate 5 is also movably connected to the bottom of the hopper mouth 1 . The first parallel closing plate 4 is installed above the second parallel closing plate 5 .

[0026] In this embodiment, a fixed hinge plate 12 is set on the first and second parallel closing plates 4 and 5, and an electric push rod 13 with a fixed ear shaft is set on the hopper body. The first and second parallel closing plates 4 and 5 are pulled together by hanging the hinge point of the head of the electric push rod 13 on the hinge plate 12. After the first and second parallel closing plates 4 and 5 rotate around the fixed axis 7, the gear 11 is driven to engage, thereby driving the first and second closing plates 2 and 3 to open and close. When a large amount of material needs to pass through, the electric push rod 13 is pulled upward to move the first and second parallel closing plates 4 and 5 upward, and the passing area is increased, thereby increasing the channel area of ​​the hopper mouth 1, so that more material can pass through. When a small amount of material needs to pass through, the electric push rod 13 is lowered to move the first and second parallel closing plates 4 and 5 downward, thereby reducing the area of ​​the hopper mouth 1, so that the amount of material passing through can be small, thereby achieving the control of material conveying volume.

[0027] See also Figure 1-4 A hinge plate 12 is provided at the bottom of the first parallel closed plate 4 , and the hinge plate 12 is also installed at the bottom of the second parallel closed plate 5 , and an electric push rod 13 is connected to the surface of the hinge plate 12 .

[0028] In this embodiment, the hinge plate 12 is made of steel plate with a hole in the middle. The point position is based on the extreme extension position of the electric push rod 13. After positioning, it should be ensured that a certain space is left between the axis of the electric push rod 13 and the first closing plate 2, the second closing plate 3, the first parallel closing plate 4, and the second parallel closing plate 5.

[0029] See also Figure 1-4 Two pairs of parallel openings are opened in the middle of the hopper mouth 1, and the first closing plate 2 and the second closing plate 3 are fixed to the fixed shaft 7 through the first steel sleeve 8 and the second steel sleeve 9 respectively.

[0030] In this embodiment, by such an arrangement, the fixing effect of the device is guaranteed during use, and the first steel sleeve 8 and the second steel sleeve 9 correspond to the first closing plate 2, the first parallel closing plate 4, the second closing plate 3, and the second parallel closing plate 5, thereby ensuring that under the fixation of the fixed shaft 7, it can be cross-lapped and used normally.

[0031] See also Figure 1-4The first parallel closing plate 4 and the second parallel closing plate 5 form an arc angle of 0-50° with the discharge direction of the hopper mouth 1, and a buffer space is provided between the first parallel closing plate 4 and the second parallel closing plate 5 to facilitate the staggered closure of the first parallel closing plate 4 and the second parallel closing plate 5 when engaged and closed.

[0032] In this embodiment, the structural height of the above structure is higher than the height of the hopper door and there is always enough space between the door side plate when the opening and closing limit positions are reached. This arrangement facilitates improving the use effect of the device.

[0033] See also Figure 1-4 The overlapping area after the first closing plate 2, the second closing plate 3, the first parallel closing plate 4 and the second parallel closing plate 5 are meshed is staggered with meshing tooth plates 6 in parallel from top to bottom. The number of meshing tooth plates 6 is several, and the spacing between two meshing tooth plates 6 is 10-20mm.

[0034] In this embodiment, the data proposed above is 10-20 mm, and the spacing needs to be changed according to the fluidity of the material to ensure that the setting of the device can match the working application scenario of the entire device.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
