Description

Technical Field

[0001] This utility model relates to the field of industrial hoppers, and more particularly to a canopy structure for an industrial hopper. Background Technology

[0002] Industrial hoppers, as key equipment for the storage and transfer of bulk materials, are widely used in mining, building materials, and chemical industries. Since most hoppers are exposed to the open environment for extended periods, their tops are typically equipped with rainproof canopies to prevent rainwater intrusion that could lead to material clumping, corrosion, or contamination. Traditional canopies often employ a left-right sliding opening and closing structure, using sliding rails on both sides to drive the canopy horizontally for opening and closing.

[0003] However, the above-mentioned sliding canopy has significant drawbacks in practical applications: First, the horizontal sliding operation requires the hopper to have lateral space on both sides that is equivalent to the length of the canopy, which greatly increases the overall footprint of the equipment and makes it difficult to deploy in space-constrained work sites; in addition, the sliding canopy is prone to lateral displacement vibration under strong wind conditions, which poses a risk of structural instability.

[0004] To address the aforementioned technical bottlenecks, the industry urgently needs to develop a canopy opening and closing solution with high space utilization, strong structural stability, and excellent sealing performance to meet the pressing needs of modern industrial sites for compact layout, low maintenance costs, and high environmental adaptability. Summary of the Invention

[0005] To address the issue of the large footprint of the equipment, this utility model proposes a canopy structure for an industrial hopper, the technical solution of which is as follows:

[0006] Includes a pair of shelves at the top of the hopper, and an opening and closing device on the side wall of the hopper, the opening and closing device causing the shelves to flip open and close relative to the hopper;

[0007] A sliding mechanism is provided on the bottom surface of the shelf panel. The sliding mechanism includes a slide rail provided on the bottom surface of the shelf panel and a movable block rotatably provided on the side of the hopper. One side of the movable block is rotatably connected to the side of the hopper, and the other side is slidably connected to the slide rail to guide and limit the bottom surface of the shelf panel, so that the shelf panel can slide relative to the movable block.

[0008] The opening and closing device includes a support arm disposed inside the hopper. One end of the support arm is a rotating connection end, and the rotating surface of the support arm is parallel to the rotating surface of the movable block. The other end of the support arm is rotatably connected to the bottom surface of the shelf away from the movable block, and the rotating surface of the support arm is perpendicular to the horizontal plane. The device also includes a driving device disposed outside the hopper. The driving device rotates the support arm, thereby driving the shelf to open to the outside of the hopper.

[0009] Furthermore, the slide rail is a linear guide rail, and the slide rail is perpendicular to the hopper side on the side where it is slidably connected to the movable block. A slider is installed on the side of the movable block near the slide rail, and the slider is slidably disposed in the slide rail.

[0010] Furthermore, each shelf panel is provided with two parallel slide rails, and for each shelf panel, two sets of opening and closing devices, driving devices and movable blocks are provided accordingly.

[0011] Furthermore, a rotating seat is provided on one side of the movable block, rotating shafts are provided on both sides of the rotating seat, and a mounting seat is provided on the side of the hopper, with the rotating shafts rotatably mounted in the mounting seat.

[0012] Furthermore, the spreading arm has a waist hole, the driving device is a hydraulic rod horizontally arranged on the outer side wall of the hopper, the movable end of the hydraulic rod is provided with a drive shaft, the drive shaft is movably locked in the waist hole perpendicular to the outer side wall of the hopper, and the outer side wall of the hopper has a clearance hole, the clearance hole provides space for the movement of the drive shaft.

[0013] Furthermore, the shelf is a rectangular plate, and when the pair of shelf panels are not retracted, they can completely cover the top opening of the hopper. When the pair of shelf panels are not retracted, they are tilted to the sides of the hopper to prevent rainwater from flowing into the hopper.

[0014] Furthermore, the side plates on both sides of the hopper extend upwards with triangular protrusions to fill the gaps created by the hopper tilting to both sides and the hopper sidewalls.

[0015] Furthermore, a rotating seat is provided at the end of the bottom surface of the shelf away from the movable block. The rotating seat has a movable groove to reserve space for the movement of the spreading arm. A movable hole is provided at the end of the spreading arm away from the rotating shaft. The spreading arm is rotatably mounted in the rotating seat through a rotating shaft coaxially arranged in the movable hole.

[0016] The beneficial effects of this invention are as follows: By combining the guide rail and the linkage drive of the expansion arm, the efficient folding and unfolding of the shelf panel is achieved. In the closed state, the shelf panel tilts to cover the top of the hopper and uses triangular protrusions for sealing, effectively preventing rainwater from seeping in; when unfolded, the hydraulically driven expansion arm moves the shelf panel outward along the guide rail, significantly reducing the overall width of the equipment. This structure adopts an external drive device and a dual guide rail system, which reduces the equipment's footprint while ensuring structural stability, making it particularly suitable for space-constrained industrial scenarios, balancing rainproof performance and space utilization.

[0022] like Figure 1 The structure of the shelf 1 of an industrial hopper 6 shown includes a pair of shelf 1s disposed on the top of the hopper 6, and an opening and closing device is provided on the side wall of the hopper 6, the opening and closing device causing the shelf 1s to flip open and close relative to the hopper 6.

[0023] like Figure 1 , Figure 2 As shown, a sliding mechanism is provided on the bottom surface of the shelf 1. The sliding mechanism includes a slide rail 2 provided on the bottom surface of the shelf 1, and a movable block 3 rotatably provided on the side of the hopper 6. One side of the movable block 3 is rotatably connected to the side of the hopper 6, and the other side is slidably connected to the slide rail 2 to guide and limit the bottom surface of the shelf 1, so that the shelf 1 can be slidably connected relative to the movable block 3.

[0024] like Figure 1 , Figure 2 As shown, the opening and closing device includes a supporting arm 4 disposed inside the hopper 6. One end of the supporting arm 4 is a rotating connection end 5, and the rotating surface of the supporting arm 4 is parallel to the rotating surface of the movable block 3. The other end of the supporting arm 4 is rotatably connected to the bottom surface of the shelf 1 away from the movable block 3, and the rotating surface of the supporting arm 4 is perpendicular to the horizontal plane. It also includes a driving device disposed on the outside of the hopper 6. The driving device causes the supporting arm 4 to rotate, thereby driving the shelf 1 to open to the outside of the hopper 6.

[0025] like Figure 2 , Figure 3 , Figure 4 As shown, preferably, the slide rail 2 is a linear guide rail, and the slide rail 2 is perpendicular to the side of the hopper 6 on the side that is slidably connected to the movable block 3. A slider 7 is installed on one side of the movable block 3. The slider 7 is slidably disposed in the slide rail 2, and a high-molecular polyethylene coating is used to cover the working surface of the slide rail 2 to reduce wear on the slider 7 and reduce noise.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, preferably, two parallel slide rails 2 are provided on a single shelf 1. For a single shelf 1, two sets of opening and closing devices, driving devices and movable blocks 3 are provided to improve the opening and closing stability of the shelf 1, distribute the load pressure, avoid the risk of single-point failure, and enhance the system redundancy.

[0027] like Figure 1 , Figure 2 , Figure 3 As shown, preferably, a rotating seat 8 is provided on one side of the movable block 3, rotating shafts are provided on both sides of the rotating seat 8, and a mounting seat is provided on the side of the hopper 6. The rotating shafts are rotatably mounted in the mounting seat. An oil injection hole is provided inside the rotating seat 8. By periodically injecting grease, the wear of the rotating shafts is reduced and the service life is extended.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown. Preferably, the spreading arm 4 has a waist hole 9, which provides stroke compensation to adapt to the rotation trajectory of the spreading arm 4; the driving device is a hydraulic rod 10 horizontally set on the outer side wall of the hopper 6, and a drive shaft 11 is provided at the movable end of the hydraulic rod 10. The drive shaft 11 is movably locked in the waist hole 9 perpendicular to the outer side wall of the hopper 6, and a clearance hole 12 is provided on the outer side wall of the hopper 6 to provide space for the movement of the drive shaft 11. In addition, the two sets of hydraulic rods 10 are synchronously extended and retracted through a central controller to ensure the symmetry of the movement of the spreading arm 4 and avoid the deflection of the shelf 1 when it is opened and closed. Since the synchronous extension and retraction of the hydraulic rods 10 is also a common technology in industry, it will not be described in detail here.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, preferably, the shelf 1 is a rectangular plate. When the pair of shelf 1 are not retracted, they can completely cover the top opening of the hopper 6. When the pair of shelf 1 are not retracted, they are tilted to both sides of the hopper 6 to prevent rainwater from flowing into the hopper 6. Waterproof strips 13 are provided at the joint of the two shelf 1s. When the two shelf 1s are closed, the strips press tightly against each other, and the shelf 1 forms a herringbone drainage surface. With the help of the sealing strip, double waterproofing is achieved, effectively preventing rainwater from seeping in.

[0030] like Figure 1 As shown, preferably, the side plates on both sides of the hopper 6 extend upward to form triangular protrusions 14 to fill the gaps created by the hopper 6 tilting to both sides and the side wall of the hopper 6, eliminate leakage paths, and improve rainproof integrity.

[0031] like Figure 1 , Figure 2 , Figure 3Preferably, a rotating seat 15 is provided at the end of the bottom surface of the shelf 1 away from the movable block 3. The rotating seat 15 has a movable groove to reserve space for the movement of the spreading arm 4. The end of the spreading arm 4 away from the rotating shaft has a movable hole. The spreading arm 4 is rotatably mounted in the rotating seat 15 via a rotating shaft coaxially arranged in the movable hole. Preferably, a waterproof strip 13 is integrated into the edge of the shelf 1. When the shelf 1 is closed, the waterproof strip 13 made of silicone is tightly attached to the side plate of the hopper 6 to form a double waterproof barrier. The silicone material adapts to minor deformations, compensates for manufacturing tolerances, forms an elastic sealing interface, and enhances waterproof reliability.

[0032] like Figure 1 , Figure 2 As shown, preferably, the shelf panel 1 is made of honeycomb aluminum plate. Under the premise of ensuring strength, the main body of the shelf panel 1 is replaced with aluminum alloy honeycomb sandwich panel to reduce the overall weight. Weight reduction holes are opened in the non-stressed area of ​​the support arm 4, while maintaining the continuous reinforcing rib structure in the waist hole 9 area to ensure mechanical performance.

[0033] It should also be noted that the hydraulic rod 10, slide rail 2, and slider 7 used in this utility model are all commonly used industrial components in the prior art. Therefore, their specific installation methods, usage conditions, usage methods, and specific structures will not be described in detail. The description of each component in the specification is only to achieve the basic functions of this utility model. Figure 4 As shown, preferably, the canopy structure in this utility model is only applicable to hoppers with a rectangular cross-section in the vertical direction.

[0034] The operating principle of this utility model is as follows: During operation, the hydraulic rod 10 extends and retracts synchronously under the command of the central controller, and the drive shaft 11 drives the expansion arm 4 to rotate around the axis through the waist hole 9. The expansion arm 4 pushes the outer end of the shelf 1 to unfold outward, while the slider 7 on the bottom surface of the shelf 1 slides along the slide rail 2, and the movable block 3 rotates around the mounting base with the movement of the shelf 1, forming a compound motion trajectory, so that the shelf 1 unfolds smoothly to the inclined protective position. When closing, the hydraulic rod 10 retracts, the expansion arm 4 rotates in the opposite direction to pull the shelf 1 back along the slide rail 2, and the sealing strip presses the side wall of the hopper 6 to form a sealed barrier. The entire process is guided by the slide rail 2 and coordinated by the rotation of the movable block 3 to ensure that the shelf 1 opens and closes without jamming; the honeycomb aluminum plate and weight-reducing design reduce the driving load, and the hydraulic synchronous control maintains the symmetry of the movement, ultimately achieving rapid opening and closing of the top of the hopper 6, reliable rain protection, and lightweight operation.

[0035] 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 this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
