Description

Technical Field

[0001] This utility model relates to the field of coal storage and transportation technology, and more specifically, to a coal storage bunker. Background Technology

[0002] In the modernization of the coal industry, coal storage and transportation have always been key research areas. Horizontal coal bunkers, as crucial facilities for coal storage and transmission, play a vital role in improving coal logistics efficiency, reducing losses, and minimizing environmental pollution. Adjusting the inclination angle of the bunker floor is one of the key technologies for controlling coal flow and preventing blockages during transport.

[0003] Traditional structures, such as simple hinges or hydraulic cylinder supports, can subject the coal bunker floor to immense pressure from the coal pile when it opens and closes, especially at a significant angle. This pressure comes not only from the weight of the coal itself but can also be exacerbated by its packing characteristics. This pressure can lead to changes in the floor's angle, deformation, or damage during use, affecting not only the accuracy of coal output but also the long-term stability and lifespan of the equipment.

The limiting protrusions are sleeved on the outer periphery of the adjusting section. Along the extension direction perpendicular to the cavity, the cross-sectional area of ​​the limiting protrusions gradually decreases along the center line of the vertical direction away from the adjusting section, and a limiting part is formed between two adjacent limiting protrusions.

[0010] Furthermore, there are two protrusions, which are arranged opposite each other on the outer periphery of the adjustment section. The first driving member is driven to connect with the two protrusions respectively to drive the two protrusions to move closer to or away from the adjustment section.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0030] like Figures 1 to 6As shown in the figure, this utility model embodiment provides a coal bunker, which is installed on a scraper conveyor. The coal bunker includes a frame 10, a bottom plate 20, and an adjustment mechanism. The frame 10 has a cavity 101 and includes a coal inlet 11 and a coal outlet 12, which are respectively connected to the cavity 101. The coal outlet 12 is located above and connected to the conveyor belt of the scraper conveyor. The bottom plate 20 is located at the coal outlet 12 and is rotatably connected to the frame 10. The rotation axis of the bottom plate 20 forms an angle with the extension direction of the cavity 101. The bottom plate 20 can open or close the coal outlet 12 to adjust the coal output of the outlet 12, thereby adapting to scraper conveyors of different speeds. The adjustment mechanism includes an adjustment section 31 and a locking section 32. The adjustment section 31 has a connecting section 311 and an adjustment section 312 that are connected to each other. The connecting section 311 is movably connected to the base plate 20, and the adjustment section 312 is movably mounted on the frame 10. The adjustment section 312 has a first locking structure, and the locking section 32 has a second locking structure. The adjustment section 31 has a locked state and an unlocked state. When the adjustment section 31 is in the unlocked state, the base plate 20 rotates, and the base plate 20 drives the adjustment section 312 to move relative to the frame 10 through the connecting section 311. When the adjustment section 31 is in the locked state, the first locking structure and the second locking structure cooperate to fix the relative position of the adjustment section 312 and the frame 10. The specific structure of the first locking structure and the second locking structure is not limited; it can be a fastener and a through hole, two snap-fit ​​devices, or a mutually engaging snap-fit ​​structure.

[0031] By applying the technical solution of this utility model, the bottom plate 20 can open or close the coal outlet 12 through rotation, thereby flexibly adjusting the coal output of the coal outlet 12. The setting of the adjustment mechanism allows the rotation of the bottom plate 20 to be precisely controlled and locked, ensuring the stability and accuracy of flow regulation. The movable design of the adjustment section 312 of the adjustment unit 31 on the frame 10, combined with the cooperation of the first locking structure and the second locking structure, allows the operator to freely adjust the inclination angle of the bottom plate in the unlocked state. After adjustment, the locking of the first locking structure and the second locking structure in the locked state ensures that the position of the bottom plate 20 remains unchanged during subsequent coal conveying, avoiding the instability problem of inclination angle commonly found in traditional adjustment methods, improving the accuracy and reliability of adjustment, reducing deformation or damage of the bottom plate 20, improving the long-term stability of the device, and extending the service life of the device.

[0032] like Figure 4As shown, the base plate 20 has a rotating end 201 and a free end 202. The rotating end 201 is rotatably connected to the frame 10. The side of the base plate 20 away from the cavity 101 has a guide groove. The guide groove extends from the free end 202 of the base plate 20 toward the rotating end 201. A slider 33 is provided on the connecting section 311. One end of the slider 33 is hinged to the connecting section 311, and the other end of the slider 33 is slidably connected to the guide groove. The slider 33 can slide along the guide groove. The guide groove can guide the sliding of the slider 33. When the base plate 20 rotates, it will drive the slider 33 to slide in the guide groove, thereby driving the connecting section 311 to move, thereby driving the adjusting section 312 to move relative to the frame 10.

[0033] Specifically, the adjusting section 312 is movably mounted on the frame 10 along the extending direction of the cavity 101. Multiple limiting portions 3121 are spaced apart along the outer periphery of the adjusting section 312 along the extending direction of the cavity 101, forming a first locking structure. The limiting portions 3121 on the adjusting section 312 cooperate with the second locking structure on the locking portion 32, achieving position fixation of the adjusting section 312 through their tight fit. A connecting section 311 is disposed between the slider 33 and the connecting section 311. One end of the connecting section 311 is fixedly connected to the adjusting section 312, and the other end of the connecting section 311 is hinged to the slider 33. Compared to rigid connections or friction drives, the hinged design reduces direct contact and wear between moving parts, lowers maintenance frequency, and extends the service life of each component.

[0034] The regulating section 312 extends vertically, as does the cavity 101. The connecting section 311 and the regulating section 312 are perpendicular to each other. When the bottom plate 20 rotates to open or close the coal outlet 12, the regulating section 312 can move precisely vertically. This not only simplifies the regulating process but also reduces the transmission effect of unnecessary lateral or oblique forces, ensuring the smoothness and accuracy of the regulating action. Multiple limiting protrusions 3122 are spaced apart along the extension direction of the cavity 101 on the outer periphery of the regulating section 312. The limiting protrusions 3122 are fitted onto the outer periphery of the regulating section 312. Along the extension direction perpendicular to the cavity 101, the cross-sectional area of ​​the limiting protrusions 3122 gradually decreases along the centerline of the vertical direction away from the regulating section 312. That is, both sides of the limiting protrusions 3122 in the vertical direction are inclined surfaces, and a limiting part 3121 is formed between two adjacent limiting protrusions 3122. The frame 10 is provided with an opening for the adjustment section 312 to pass through. With this design, when the limiting protrusion 3122 gets stuck relative to the through hole, the inclined surfaces on both sides of the limiting protrusion 3122 in the vertical direction can guide it, allowing for quick release of the obstruction. Simultaneously, the design of multiple limiting protrusions 3122 enables fine-tuning. That is, when the rotation angle of the base plate 20 is small, the adjustment section 312 can also be locked by the matching limiting protrusions 3122 at different positions, achieving precise locking of the opening angle of the base plate 20 and further improving the reliability of the device.

[0035] Specifically, the limiting protrusion 3122 is a triangular prism structure.

[0036] like Figure 6As shown, the locking part 32 includes a protrusion 321 and a first driving member. The protrusion 321 is movably mounted on the frame 10 and engages with a limiting part 3121 to fix the relative position of the adjusting section 312 and the frame 10, forming a second locking structure. The protrusion 321 can engage with the limiting part 3121 on the adjusting section 312. This engagement structure is not only simple but also allows for quick engagement and disengagement, making it simple to operate. The first driving member has a fixed end 3221 and a moving end 3222. The fixed end 3221 is fixedly connected to the frame 10, and the moving end 3222 is connected to the protrusion 321. Along the extension direction perpendicular to the cavity 101, the moving end 3222 can move relative to the fixed end 3221, allowing it to move closer to or further away from the adjusting section 312, thereby driving the protrusion 321 to engage with the limiting parts 3121 at different positions on the adjusting section 312. The mobile end 3222 drives the protrusion 321 to move closer to or further away from the adjusting section 312, thereby precisely controlling the engagement of the protrusion 321 with the limiting part 3121 at different positions, ensuring that the base plate 20 can be reliably locked at any tilt angle. The setting of the first driving member makes the entire locking process more automated, improving operating efficiency and the intelligence level of the device.

[0037] Specifically, there are two protrusions 321, which are arranged opposite to each other on the outer periphery of the adjustment section 312. The first driving member is driven to connect with the two protrusions 321 respectively, so as to drive the two protrusions 321 to move closer to or away from the adjustment section 312. The two protrusions 321 cooperate with each other and engage with the limiting part 3121. Through the relative movement of the two protrusions 321, the adjustment section 312 is double-locked, which improves the stability and reliability of the locking.

[0038] Specifically, the first driving component is a bidirectional electric push rod, and a controller 50 is provided on the frame 10, which is connected to the first driving component.

[0039] like Figure 5As shown, the coal bunker also includes a second driving component 41 and a transmission assembly. The second driving component 41 is mounted on the frame 10 and has an output end 411 located outside the cavity 101. The rotation axis of the output end 411 is parallel to the rotation axis of the bottom plate 20. The second driving component 41 can control the rotation of the bottom plate 20 without manual operation, greatly improving adjustment efficiency and operational safety. The transmission assembly is located between the output end 411 and the bottom plate 20. The output end 411 is driven to the transmission assembly, and the transmission assembly is driven to the bottom plate 20 to drive its rotation. The addition of the transmission assembly acts as a power transmission bridge between the output end 411 and the bottom plate 20, accurately transmitting the rotational force of the second driving component 41 to the bottom plate 20, driving it to rotate along a preset path to the required angle. Furthermore, the transmission assembly enhances the flexibility of the drive, allowing the transmission path to be changed, thus enabling the adjustment and selection of the positions of the second driving component 41 and the bottom plate 20 according to design requirements. The coal bunker also includes a detection unit, which monitors the rotation angle of the bottom plate 20. Through this unit, operators can instantly understand the actual position of the bottom plate 20 and adjust the working state of the second drive component 41 in a timely manner, thus avoiding coal handling problems caused by angular deviations.

[0040] The detection unit can be an angle sensor, which is mounted on the rotating shaft of the rotating end 201 of the base plate 20, or on the output end 411 of the second drive component 41. The second drive component 41 is a motor, and a power supply 60 is also provided on the frame 10. The power supply 60 provides the required energy to the components in the device that require electricity.

[0041] Furthermore, the transmission assembly includes a main gear 42, a first gear 43, and a limiting shaft 44. The main gear 42 is drivenly connected to the output end 411, and the rotation axis of the main gear 42 coincides with the rotation axis of the output end 411. This power transmission method reduces power loss and increases the adjustment speed of the base plate 20. The first gear 43 is mounted on the frame 10 and corresponds to the base plate 20. The first gear 43 is drivenly connected to the base plate 20, and the base plate 20 is connected to the first gear 43 via a rotating shaft and rotates synchronously. The first gear 43 has a limiting hole 431, which is arranged circumferentially along the first gear 43. The transmission of the gear assembly further improves the fine control of the rotation angle of the base plate 20, thus allowing for more precise control of the opening degree of the coal outlet 12 and improving the precise adjustment of the coal output of the coal outlet 12. A limiting shaft 44 is mounted on the frame 10. The extending direction of the limiting shaft 44 is the same as that of the output end 411. The end of the limiting shaft 44 passes through the limiting hole 431 and can engage with the end of the limiting hole 431 along the circumferential direction of the first gear 43 to limit the rotation range of the first gear 43. When the first gear 43 rotates to the preset position, the limiting shaft 44 can engage with the end of the limiting hole 431, thereby preventing the first gear 43 from continuing to rotate, preventing excessive rotation of the base plate 20 from causing safety hazards or damage to the device, and ensuring the safe and stable operation of the equipment.

[0042] like Figure 4 As shown, there are two base plates 20, which are positioned opposite each other at the coal outlet 12 and cooperate to open or close the coal outlet 12. The design of the two base plates 20 enables rapid adjustment of the coal output. There are two adjustment mechanisms, each corresponding to one of the two base plates 20. The transmission assembly also includes a secondary gear 45, a second gear 46, and a chain 47. The secondary gear 45 is located on the side of the main gear 42 away from the frame 10 and rotates synchronously with the main gear 42. The second gear 46 is mounted on the frame 10. The first gear 43 and the second gear 46 are respectively positioned corresponding to the two base plates 20, with the second gear 46 spaced apart from the first gear 43. The chain 47 is positioned between the secondary gear 45 and the second gear 46. This arrangement ensures the synchronicity of the two base plates 20 during adjustment, avoiding the problem of uneven coal flow caused by adjusting only one base plate.

[0043] When it is necessary to speed up the coal discharge speed, the openings of the two bottom plates 20 can be adjusted to the maximum; when it is necessary to slow down the coal flow, the openings can be reduced or even completely closed to achieve the required flow control effect.

[0044] Furthermore, the frame 10 is provided with a first splicing structure and a second splicing structure, which are horizontally spaced on both sides of the frame 10, and their structural outlines are compatible. Through the splicing of the first and second splicing structures, the frame 10 can be quickly assembled and disassembled, realizing the modular design of the frame 10 and improving the flexibility and maintainability of the coal bunker.

[0045] Specifically, the frame 10 includes a body 13, which has a cavity 101, a coal inlet 11, and a coal outlet 12. Horizontally, the top of the body 13 has a first enclosure 131 extending outward from the coal inlet 11. The bottom of the first enclosure 131 has multiple first support rods 15. The bottom of the body 13 has a second enclosure 132 extending outward from the coal outlet 12. The bottom of the second enclosure 132 has multiple second support rods 16. Openings for the adjustment section 312 and locking parts 32 are both provided on the second enclosure 132. Multiple baffles 14 are sequentially arranged along the bottom edge of the second enclosure 132. The baffles 14 prevent coal blocks from falling from the coal outlet 12 and then flying off the side of the frame 10, thus ensuring the accuracy of coal conveying.

[0046] The top of the adjusting section 312 has a limiting plate, the size of which is larger than the size of the opening through which the adjusting section 312 passes, so as to prevent the adjusting section 312 from coming out of the opening when it moves.

[0047] like Figures 1 to 3 As shown, the top of the first enclosure 131 is also provided with multiple handrails 17 along the horizontal direction, which can prevent workers from falling.

[0048] In some embodiments, one end of the handrail 17 has a first protrusion 171 and the other end of the handrail 17 has a first groove 172. When multiple frames 10 are spliced ​​together, the first protrusion 171 on one of the frames 10 can be inserted into the first groove 172 on the adjacent frame 10. The two adjacent frames 10 can be connected by the first protrusion 171 and the first groove 172.

[0049] In other embodiments, one end of the first enclosure 131 has a second protrusion 1311 and the other end of the first enclosure 131 has a second groove 1312. When multiple frames 10 are spliced ​​together, the second protrusion 1311 on one of the frames 10 can be inserted into the second groove 1312 on the adjacent frame 10. The two adjacent frames 10 can be connected by the second protrusion 1311 and the second groove 1312.
