Description

Technical Field

[0001] This invention relates to the field of flow guide skirt technology, and more particularly to a flow guide skirt for preventing spillage during bulk cargo unloading. Background Technology

[0002] In bulk cargo handling scenarios such as ports, warehouses, and mines, bulk cargo unloading is a core link in material transfer. During the process of unloading bulk cargo such as coal, ore, and grain from containers to conveying equipment, unloading equipment (such as tippers and hoppers) is prone to spillage and splashing due to the impact of falling materials and the inertia of flow. This not only causes material loss but also pollutes the working environment, increases the workload of on-site cleaning, and may even cause equipment jamming and personnel slipping due to the accumulation of materials. To solve the above problems, anti-spillage guide skirts are widely used at the unloading port of bulk cargo unloading equipment as a key protective component. Their core function is to guide the direction of material flow and block the range of material splashing, so as to achieve precise guidance of bulk cargo, reduce spillage loss and environmental impact, and at the same time help stabilize the material conveying state and protect the normal operation of surrounding equipment. However, most existing guide skirt angle adjustments on the market use the traditional method of manual bolt tightening and pin positioning. The adjustment process requires completing multiple steps in sequence, which takes a lot of time. In scenarios where unloading operations require frequent switching of bulk cargo types and adjustment of working conditions, this seriously delays the operation progress and affects unloading efficiency. Moreover, the accuracy of the adjustment angle depends entirely on the operator's visual judgment and manual experience, which is prone to angle deviation. If the adjustment is not in place, it is necessary to disassemble and adjust repeatedly, further exacerbating the cumbersome operation. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a solution to the problems described in the background art.

[0004] Technical solution: A spill-proof guide skirt for unloading bulk cargo, comprising a U-shaped mounting plate, wherein connecting rods are symmetrically arranged on the lower side of the outer wall of the U-shaped mounting plate, and the outer walls of the two connecting rods are fixedly connected to the guide skirt body, and limiting circular plates are fixedly connected to the opposite ends of the two connecting rods on both sides of the guide skirt body.

[0005] Furthermore, both outer walls of the two connecting rods are fixedly connected to driven gears. The front and rear surfaces of the U-shaped mounting plate, located above the two driven gears, are rotatably connected to master gears via rotating shafts. The outer walls of the two driven gears are respectively meshed with the outer walls of the two master gears. Control motors are provided on the opposite sides of the two master gears. The output shafts of the two control motors are respectively fixedly connected to the center of the opposite sides of the two master gears. The opposite sides of the two control motors are respectively fixedly connected to the front and rear surfaces of the U-shaped mounting plate with L-shaped fixing plates.

[0006] Furthermore, the front and rear surfaces of the U-shaped mounting plate are provided with multiple through mounting holes.

[0007] Furthermore, the front and rear surfaces of the U-shaped mounting plate, located above the two L-shaped fixing plates, are fixedly connected to fixing boxes. Sliding blocks are slidably connected inside the two fixing boxes. Sliding cavities are integrally formed inside the two sliding blocks. Movable plates are slidably connected inside the two sliding cavities. The opposite sides of the interiors of the two sliding cavities, together with the opposite sides of the two fixing boxes, have protrusion openings. Inclined fixing blocks are fixedly connected to the opposite sides of the two movable plates. Multiple springs are fixedly connected to the opposite sides of the interiors of the two sliding cavities, respectively. Locking grooves are formed on the front and rear surfaces of the inner wall of the guide skirt body.

[0008] Furthermore, electric telescopic rods are fixedly connected to the opposite sides of the interior of the two fixed boxes, and the output ends of the two electric telescopic rods are fixedly connected to the opposite sides of the two sliding blocks, respectively.

[0009] Furthermore, both of the two gears have through-type arc-shaped limiting grooves on their opposite sides, and each of the two arc-shaped limiting grooves has a limiting rod inside. The opposite ends of the two limiting rods are fixedly connected to the front and rear surfaces of the U-shaped mounting plate, respectively.

[0010] Furthermore, the U-shaped mounting plate has symmetrically arranged control cavities inside. The opposing sides of the two control cavities are rotatably connected to connecting columns via rotating shafts. The opposing sides of the two connecting columns are fixedly connected to the opposite sides of the two connecting rods. The outer walls of the two connecting columns are provided with multiple positioning holes. Electric push rods are fixedly connected to the left side of the two control cavities. The right ends of the output shafts of the two electric push rods are fixedly connected to positioning rods. The right ends of the two positioning rods extend into the interiors of the two positioning holes on the left side.

[0011] Beneficial effects: This invention achieves automatic angle adjustment of the guide skirt body through motor-driven gear meshing transmission. Compared with the traditional manual adjustment structure, it eliminates the need for manual disassembly and assembly of locking components with the aid of tools. It can quickly complete angle adjustment according to the type of bulk cargo, unloading speed and working conditions, greatly improving adjustment efficiency and ease of operation. At the same time, the symmetrically arranged transmission structure on both sides distributes the force evenly, which can effectively avoid problems such as jamming and skew during the adjustment process, ensuring that the guide skirt body moves smoothly and steadily. This invention uses an arc-shaped limiting groove and a limiting rod to precisely limit the rotation range of the guide skirt body, preventing collision interference caused by overtravel rotation. The electric push rod drives the positioning rod to insert into the positioning hole on the connecting column, which can achieve rigid locking after the angle is adjusted to the correct position. This effectively resists loosening and displacement caused by the impact of bulk materials and equipment vibration, ensuring that the guide angle is always stable and reliable, and significantly improving the safety of device operation and the stability of guide flow. When the guide skirt body is not in use, the present invention can be rotated upward to be horizontal with the U-shaped mounting plate. The inclined fixing block automatically snaps into the locking groove under the action of the spring to complete the fixation, reducing the space occupied by the equipment and avoiding damage from idleness. When operation is required, it can be quickly unlocked by the electric telescopic rod, realizing flexible switching between storage and working states. At the same time, the overall structure is compact and reasonable, and the installation and maintenance are convenient. It can effectively improve the continuity of bulk cargo unloading operations and reduce material spillage loss and equipment maintenance costs. Attached Figure Description

[0014] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0015] like Figure 1 and Figure 2 As shown, a spill-proof guide skirt for unloading bulk cargo is provided, including a U-shaped mounting plate 1. Connecting rods 2 are symmetrically arranged below the outer side wall of the U-shaped mounting plate 1. The outer side walls of the two connecting rods 2 are fixedly connected to the guide skirt body 3. Limiting circular plates 4 are fixedly connected to the opposite ends of the two connecting rods 2 on both sides of the guide skirt body 3. Both connecting rods 2 have a driven gear 5 fixedly connected to their outer side walls. The front and rear surfaces of the U-shaped mounting plate 1, located above the two driven gears 5, are rotatably connected to a main gear 6 via a rotating shaft. The outer side walls of the two driven gears 5 are meshed with the outer side walls of the two main gears 6 respectively. A control motor 7 is provided on the opposite side of the two main gears 6. The output shaft ends of the two control motors 7 are fixedly connected to the center of the opposite side of the two main gears 6 respectively. The opposite side of the two control motors 7 are fixedly connected to the front and rear surfaces of the U-shaped mounting plate 1 together with an L-shaped fixing plate 8. The U-shaped mounting plate 1 enables rapid positioning and installation of the entire device, adapting to the conventional installation structure of the unloading port of bulk cargo tipping equipment. This ensures stable installation and convenient disassembly. The guide skirt body 3, fixedly connected to the outer walls of the two connecting rods 2, conforms to the flow trajectory of bulk cargo, effectively preventing material splashing and leakage, and improving the airtightness and flow guidance effect during unloading. The driven gear 5, fixedly connected to the outer walls of the two connecting rods 2, works with the main gear 6, which is rotated through a shaft on the front and rear surfaces of the U-shaped mounting plate 1, to form a stable meshing transmission structure. The meshing transmission between the main gear 6 and the driven gear 5 ensures smooth torque transmission, guaranteeing a smooth and uninterrupted angle adjustment process. The control motor 7, located on the opposite sides of the two main gears 6, provides stable power for angle adjustment, eliminating the need for manual operation. The automatic and precise adjustment of the guide angle significantly improves the convenience of adjustment and work efficiency. The L-shaped fixing plate 8, which is fixedly connected to the front and rear surfaces of the U-shaped mounting plate 1 on the back side of the two control motors 7, can firmly support the control motors 7, preventing them from loosening or shifting under equipment vibration and material impact. This ensures that the transmission structure always maintains precise meshing. The overall device has a compact and reasonable structure. The angle of the guide skirt body 3 is automatically adjusted through the meshing transmission of the motor-driven gears. With the limit protection of the limiting circular plate 4, it not only solves the problems of cumbersome adjustment and unstable fixing of traditional skirts, but also allows for rapid adjustment of the guide angle according to different bulk material characteristics and working conditions, improving the anti-spillage effect. At the same time, it enhances the reliability and service life of the device, and reduces the intensity of manual operation and equipment maintenance costs.

[0016] like Figure 1 and Figure 2 As shown, the front and rear surfaces of the U-shaped mounting plate 1 are provided with multiple through mounting holes 9; The multiple through-holes 9 allow for stable installation of the device at the corresponding position on the bulk cargo unloading equipment using bolts and other fasteners. These through-holes 9 provide multiple evenly distributed stress connection points, enhancing installation stability and preventing overall loosening or displacement under material impact and equipment vibration. Furthermore, the installation position can be fine-tuned by selecting different mounting holes 9, improving the device's compatibility with bulk cargo unloading equipment of different specifications. The through-hole design of the mounting holes 9 facilitates quick fastener insertion for disassembly and assembly, further improving the convenience of on-site installation and maintenance, and providing a reliable installation foundation for the stable operation of the subsequent angle adjustment mechanism.

[0017] like Figures 1-3 As shown, a fixed box 10 is fixedly connected to the front and rear surfaces of the U-shaped mounting plate 1 above the two L-shaped fixed plates 8. Sliding blocks 11 are slidably connected inside the two fixed boxes 10. Sliding cavities 12 are integrally formed inside the two sliding blocks 11. Movable plates 13 are slidably connected inside the two sliding cavities 12. The opposite sides of the interior of the two sliding cavities 12 and the opposite sides of the two fixed boxes 10 are respectively provided with an extension opening 14. Inclined fixed blocks 15 are fixedly connected to the opposite sides of the two movable plates 13. Multiple springs 16 are fixedly connected to the opposite sides of the interior of the two sliding cavities 12. Locking grooves 17 are provided on the front and rear surfaces of the inner sidewall of the guide skirt body 3. Electric telescopic rods 18 are fixedly connected to the opposite sides of the interior of the two fixed boxes 10, and the output ends of the two electric telescopic rods 18 are fixedly connected to the opposite sides of the two sliding blocks 11 respectively. When the guide skirt body 3 is not in use, the guide skirt body 3 can be rotated upward by controlling the motor 7. During the rotation, the outer side of the guide skirt body 3 will press the inclined fixing blocks 15 on both sides. After the inclined fixing blocks 15 are pressed, they will drive the movable plate 13 to compress the spring 16 and retract into the sliding cavity 12. After the guide skirt body 3 rotates to the set position, the locking groove 17 is aligned with the inclined fixing block 15. The spring 16 resets and pushes the movable plate 13 and the inclined fixing block 15 to extend and lock into the locking groove 17. Thus, the guide skirt body 3 can be fixed by the two inclined fixing blocks 15. At this time, the guide skirt body 3 is completely retracted and kept horizontal with the U-shaped mounting plate 1, which can effectively reduce the space occupied by the equipment and avoid collision damage when idle. When needed, the electric telescopic rod 18 can be used to... The contraction of the sliding block 11, the movable plate 13, and the inclined fixing block 15 can move synchronously, pulling the two inclined fixing blocks 15 out of the locking groove 17, releasing the locking constraint on the guide skirt body 3. Then, the guide skirt body 3 can be driven downward to the working angle by controlling the motor 7. The overall structure realizes the automatic storage and locking and quick unlocking and unfolding of the guide skirt body 3. With the elastic pressing of the spring 16 and the driving control of the electric telescopic rod 18, it not only ensures the stability and reliability in the storage state, but also improves the convenience of operation when switching working conditions. At the same time, the sliding cooperation between the sliding block 11 and the fixed box 10, and the sliding connection between the movable plate 13 and the sliding cavity 12 can ensure smooth and stable movement, avoid jamming, and further improve the stability and service life of the device.

[0018] like Figure 2 As shown, two through arc-shaped limiting grooves 19 are provided on the opposite sides of the gear 5, and limiting rods 20 are provided inside the two arc-shaped limiting grooves 19. The opposite ends of the two limiting rods 20 are fixedly connected to the front surface and the rear surface of the U-shaped mounting plate 1, respectively. The arc-shaped limiting groove 19 and the limiting rod 20 work together to precisely limit the rotation range of the driven gear 5, and then effectively limit the rotation angle of the guide skirt body 3 through the connecting rod 2. This prevents the guide skirt body 3 from rotating too much or too little during the adjustment process driven by the control motor 7, and prevents collisions or interference with surrounding equipment due to overtravel rotation, or the guide angle from failing to meet the operational requirements. At the same time, the sliding cooperation between the limiting rod 20 and the arc-shaped limiting groove 19 ensures that the driven gear 5 rotates smoothly without jamming. While achieving angle limiting, it does not affect normal adjustment operations, further improving the accuracy of the angle adjustment of the guide skirt body 3 and the operational safety, and ensuring the stable and orderly operation of bulk cargo unloading.

[0019] like Figure 4As shown, the U-shaped mounting plate 1 has symmetrically arranged control cavities 21 inside. The opposing sides of the two control cavities 21 are rotatably connected to the connecting posts 22 via rotating shafts. The opposing sides of the two connecting posts 22 are fixedly connected to the opposite sides of the two connecting rods 2. The outer walls of the two connecting posts 22 are provided with multiple positioning holes 23. The left side of the two control cavities 21 is fixedly connected to electric push rods 24. The right end of the output shaft of the two electric push rods 24 is fixedly connected to positioning rods 25. The right ends of the two positioning rods 25 extend into the interior of the two positioning holes 23 on the left side. When the guide skirt body 3 is adjusted to a suitable working angle under the drive of the control motor 7, the two electric push rods 24 can push the positioning rod 25 to extend and insert into the corresponding positioning hole 23. The connecting column 22 is firmly locked by the insertion and cooperation of the positioning rod 25 and the positioning hole 23. Thus, the angle of the guide skirt body 3 is reliably fixed by the connecting rod 2, which effectively avoids problems such as angle deviation, loosening and shaking under the impact of bulk materials and equipment vibration. Multiple positioning holes 23 can be adapted to the locking requirements of different adjustment angles, ensuring stable positioning under different working conditions. The rotational cooperation structure of the connecting column 22 and the control cavity 21 is compact and reasonable. While realizing angle adjustment, it provides a stable installation space for the locking mechanism. The overall locking action is rapid and accurate in positioning, further improving the stability of device operation and the reliability of guide operation.
