Description

Technical Field

[0001] This utility model relates to the field of bucket elevator technology, and more specifically, to a bucket elevator capable of automatic material unloading. Background Technology

[0002] Bucket elevators are a type of vertical conveying equipment for continuously transporting powdery, granular, or small lump materials. They are driven by traction components (belts or chains) to circulate and lift buckets within a closed casing. Material is lifted by loading from the bottom and unloading from the top. They are characterized by their compact structure, large conveying capacity, and small footprint.

[0003] In order to facilitate material discharge, existing bucket elevators use a fixed connection between the bucket and the chain, with the feeding end located at the bottom of the equipment, or a rotating connection. An electronic control structure is added to the discharge port to assist the bucket rotation. The fixed connection method leads to serious material spillage from the bucket, while the rotating connection method has a higher manufacturing cost.

[0004] In summary, in order to balance the unloading efficiency and manufacturing cost of bucket elevators, it is necessary to solve the problems of serious material spillage in fixed connection methods and the complex structure and high cost of rotating connection methods, so that the buckets remain stable during the lifting process and achieve reliable overturning during unloading, while simplifying the structure and reducing maintenance difficulty. Utility Model Content

[0005] The bucket elevator with automatic unloading provided by this utility model aims to solve the following problem: the existing bucket elevator bucket connection methods present a dilemma, with fixed connections being prone to material spillage and rotating connections being costly.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic bucket elevator, comprising a fixed frame, a drive shaft rotatably connected to the fixed frame via bearing seats, two drive gears mounted on the outer side of the drive shaft, tensioning mechanisms provided at the lower ends of both the front and rear sides of the fixed frame, connecting discs mounted on the tensioning mechanisms, adjusting gears rotatably connected to the connecting discs, multiple sets of steering gears installed inside the fixed frame, first chains sleeved on the outer sides of the drive gears, adjusting gears, and steering gears, multiple connecting plates mounted on the two first chains, positioning discs provided between corresponding two connecting plates, a hopper fixed between the two positioning discs, positioning shafts rotatably connected to the outer sides of the positioning discs, positioning shafts rotatably connected to the connecting plates, rollers rotatably connected to the connecting plates, fixed wheels mounted on the outer side of the drive shaft, driven gears also mounted on the outer side of the drive shaft, a drive motor provided at the top of the fixed frame, a drive gear mounted at the output end of the drive motor, second chains sleeved on the outer sides of the drive gears and driven gears, a material leveling mechanism provided on the top right side of the fixed frame, and support plates fixed inside the fixed frame corresponding to the horizontal sections of the first chains.

[0007] In a preferred embodiment, the tensioning mechanism includes a sliding component and an adjusting component. The sliding component is used to adjust the lateral position of the connecting plate and the adjusting gear, and the adjusting component is used to drive the sliding component to move left and right.

[0008] In a preferred embodiment, the sliding assembly includes fixed plates fixed on the front and rear sides of the fixed frame, and guide rails are fixed on both fixed plates. The guide rails have grooves inside, and a slide block is slidably connected to the inside of the guide rails through the grooves. The slide block is fixedly connected to the connecting plate, and the fixed plates have slots for the connecting plate to move.

[0009] In a preferred embodiment, the adjustment assembly includes an adjustment screw threaded to the left side of the guide rail, the right end of the adjustment screw passing through the left side wall of the guide rail and rotatably connected to the slide, the left end of the adjustment screw being fitted with a knob for rotating the adjustment screw, and a protective cover being fitted to the outside of the fixing plate.

[0010] In a preferred embodiment, the material leveling mechanism includes a material blocking component and a leakage prevention component. The material blocking component is used to evenly distribute the material in the high-flow-out hopper, and the leakage prevention component is used to reduce material spillage.

[0011] In a preferred embodiment, the material blocking assembly includes a feed inlet disposed on a fixed frame, and a material leveling plate is installed on the bottom left side of the feed inlet.

[0012] In a preferred embodiment, the leak-proof assembly includes a first shelf fixed to the right side of the hopper and a second shelf fixed to the left side of the hopper, the first shelf being slightly higher than the second shelf.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention cleverly designs a mechanical linkage structure between the fixed wheel and the positioning plate, enabling the bucket to automatically trigger a flipping action when it reaches the unloading position. This solution requires no additional electrical control device and can achieve stable unloading solely through a purely mechanical structure. It avoids the material spillage problem caused by traditional fixed connections and significantly reduces the manufacturing cost of rotating connections. Its automated flipping mechanism is reliable in operation and easy to maintain, effectively improving the conveying efficiency and material recovery rate of the bucket elevator. At the same time, it reduces equipment energy consumption and the need for manual intervention, making it particularly suitable for scenarios requiring continuous and stable operation for lifting powdery and granular materials.

Detailed Implementation

[0022] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0023] Refer to the instruction manual appendix Figures 1 to 6The bucket elevator with automatic unloading capability includes a fixed frame 1. A drive shaft 2 is rotatably connected to the fixed frame 1 via bearing seats. Two drive gears 3 are mounted on the outer side of the drive shaft 2. Tensioning mechanisms are provided at the lower ends of both the front and rear sides of the fixed frame 1. Connecting discs 5 are mounted on the tensioning mechanisms. Adjusting gears 6 are rotatably connected to the upper part of the connecting discs 5. Multiple sets of steering gears 7 are installed inside the fixed frame 1. First chains 8 are sleeved on the outer sides of the drive gears 3, adjusting gears 6, and steering gears 7. Multiple connecting pieces 9 are mounted on the two first chains 8. Positioning discs 10 are provided between corresponding two connecting pieces 9. A hopper 11 is fixed in the middle. A positioning shaft 12 is rotatably connected to the outside of the positioning plate 10. The positioning shaft 12 is rotatably connected to the connecting piece 9. A roller 13 is rotatably connected to the connecting piece 9. A fixed wheel 14 is installed on the outside of the transmission shaft 2. A driven gear 15 is also installed on the outside of the transmission shaft 2. A drive motor 16 is set on the top of the fixed frame 1. A drive gear 17 is installed on the output end of the drive motor 16. A second chain 18 is sleeved on the outside of the drive gear 17 and the driven gear 15. A material leveling mechanism is set on the top right side of the fixed frame 1. Support plates 20 are fixed inside the fixed frame 1 corresponding to the horizontal section of the first chain 8.

[0024] It should be noted that the connecting piece 9 is fixedly connected to the first chain 8. As the first chain 8 moves and changes direction, the rotatable connection between the connecting piece 9 and the positioning shaft 12 ensures that the hopper 11 remains balanced under the action of gravity. When the hopper 11 moves to the horizontal section, the rollers 13 at both ends will roll along the support plate 20, thereby preventing the first chain 8 from deforming. When it moves to the discharge port position, the positioning plate 10 is blocked by the fixed wheel 14 and will slide along the surface of the fixed wheel 14, thereby causing the hopper 11 to deflect and achieve the tilting action.

[0025] In this embodiment, the specific implementation scenario is as follows: when it is necessary to adjust the lateral distance, the brackets on the front and rear sides of the fixed frame 1 used for mounting the transmission shaft 2 and the fixed base plate of the drive motor 16 can be moved. By changing the lateral position of these three positioning structures, the purpose of extending or shortening the frame and increasing or decreasing the number of chain links (i.e., the number of hoppers 11) can be achieved.

[0026] Refer to the instruction manual appendix Figure 3 and Figure 4 The tensioning mechanism includes a sliding component and an adjusting component. The sliding component is used to adjust the lateral position of the connecting plate 5 and the adjusting gear 6, and the adjusting component is used to drive the sliding component to move left and right.

[0027] It should be noted that by adjusting the component, the sliding component can be moved left and right, thereby controlling the tension of the first chain 8.

[0028] Refer to the instruction manual appendix Figure 3 and Figure 4The sliding assembly includes fixed plates 41 fixed on the front and rear sides of the fixed frame 1. Guide rails 42 are fixed on both fixed plates 41. The guide rails 42 have grooves 44 inside. A slide block 43 is slidably connected inside the guide rails 42 through the grooves 44. The slide block 43 is fixedly connected to the connecting plate 5. The fixed plates 41 have slots for the connecting plate 5 to move.

[0029] It should be noted that the slide block 43 slides left and right along the slide groove 44 inside the guide rail 42, thereby driving the connecting plate 5 to slide synchronously along the groove.

[0030] Refer to the instruction manual appendix Figure 4 The adjustment assembly includes an adjustment screw 45 threaded to the left side of the guide rail 42. The right end of the adjustment screw 45 passes through the left side wall of the guide rail 42 and is rotatably connected to the slide block 43. A knob 46 for rotating the adjustment screw 45 is installed on the left end of the adjustment screw 45. A protective cover 47 is installed on the outside of the fixing plate 41.

[0031] It should be noted that the adjusting screw 45 can be rotated by the knob 46. When the adjusting screw 45 is rotated, it moves left and right along the left side wall of the guide rail 42, thereby driving the slide 43 to move.

[0032] Refer to the instruction manual appendix Figure 3 and Figure 4 The material distribution mechanism includes a material blocking component and a leak prevention component. The material blocking component is used to evenly distribute the material that is above the material hopper 11, and the leak prevention component is used to reduce material spillage.

[0033] It should be noted that the material blocking component is set on the fixed frame 1, and the leak-proof component is set on the hopper 11.

[0034] Refer to the instruction manual appendix Figure 3 and Figure 4 The material blocking assembly includes a feed inlet 191 disposed on the fixed frame 1, and a material leveling plate 192 is installed on the bottom left side of the feed inlet 191.

[0035] It should be noted that by setting up the material leveling plate 192, after the material is poured into the hopper 11, as the hopper 11 moves past the material leveling plate 192, the material that is higher than the hopper 11 will be pushed by the material leveling plate 192 to the inner side of the adjacent hopper 11, thereby ensuring the uniformity of the feeding.

[0036] Refer to the instruction manual appendix Figure 3 , Figure 4 and Figure 5 The leak-proof component includes a first shelf 193 fixed to the right side of the hopper 11 and a second shelf 194 fixed to the left side of the hopper 11. The horizontal height of the first shelf 193 is slightly higher than that of the second shelf 194.

[0037] It should be noted that multiple hoppers 11 are arranged adjacent to each other on the first chain 8. The number of hoppers 11 can be adjusted by the staff according to actual needs. After the hoppers 11 are installed, the first shelf 193 on the left hopper 11 will be placed on the upper side of the second shelf 194 on the right hopper 11, thereby covering the gap between the two hoppers 11 and preventing material leakage.

[0038] Working principle: The drive motor 16 starts, and drives the second chain 18 through the drive gear 17 at its output end. The second chain 18 drives the driven gear 15 on the transmission shaft 2 to rotate. The transmission shaft 2 rotates accordingly, driving the drive gear 3 and the fixed wheel 14 on it to rotate. The drive gear 3 drives the first chain 8, and the first chain 8 drives the connecting piece 9 fixedly connected to it to move. The connecting piece 9 is rotatably connected to the positioning disk 10 through the positioning shaft 12. The positioning disk 10 is fixedly connected to the hopper 11. The hopper 11 always maintains balance under the action of gravity. When the first chain 8 drives the hopper 11 to move to the horizontal section inside the fixed frame 1, the roller 13 on the connecting piece 9 rolls along the support plate 20, supporting the first chain 8 and preventing it from sagging due to gravity. When the hopper 11 moves to the top discharge port position, the positioning disk 10 is subjected to... When the fixed wheel 14 on the drive shaft 2 blocks the locating disc 10, the locating disc 10 slides along the surface of the fixed wheel 14, forcing the locating disc 10 and the hopper 11 fixed thereto to deflect around the locating shaft 12, thereby realizing the automatic tilting action of the hopper 11. By rotating the adjusting screw 45, the slide block 43 is driven to slide left and right in the slide groove 44 of the guide rail 42, thereby driving the connecting disc 5 and the adjusting gear 6 to move laterally to adjust the tension of the first chain 8. When feeding, the material falls into the hopper 11 from the feed port 191. The material that is higher than the hopper 11 is pushed to the adjacent hopper 11 behind by the equalizing plate 192 when the hopper 11 moves past the equalizing plate 192. When multiple hoppers 11 are installed adjacent to each other, the first shelf 193 on the left hopper 11 rests on the second shelf 194 on the right hopper 11 to cover the gap between the hoppers 11 and reduce material spillage.

[0039] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
