Description

Technical Field

[0001] The utility model relates to the technical field of bucket elevators, in particular to a feeding device for a bucket elevator. Background Art

[0002] A bucket elevator is a continuous conveying machine that uses a series of buckets fixedly connected to an endless traction member to vertically lift materials. The bucket elevator uses a series of buckets fixedly connected to a traction chain or a belt to transport bulk materials upward in a vertical or nearly vertical direction. The bucket elevator is a device widely used in material conveying, and its core function is to lift materials from a low place to a high place;

[0003] After retrieval, a Chinese utility model patent with the publication number CN215325034U, titled a feeding device for a bucket elevator, includes two L-shaped support legs. The top surfaces of the two L-shaped support legs are fixedly connected with a storage bin. A crushing mechanism is arranged inside the storage bin. The crushing mechanism includes a first shaft rod whose two ends are rotatably connected to the inner side wall of the storage bin. A crushing wheel is sleeved and fixed on the outer side wall of the first shaft rod. A plurality of crushing frames are fixedly connected to the outer side wall of the crushing wheel at equal intervals. The caked materials in the storage bin are crushed by the crushing frames on the crushing mechanism, preventing the materials with a large volume from blocking the feeding port and ensuring the smooth conveying of the materials. The conveyor belt on the feeding mechanism evenly conveys the materials to the feeding port, effectively preventing the materials from impacting the buckets.

[0004] However, it is found in the use process that during the feeding process of the bucket elevator, the feeding amount cannot be accurately controlled, which affects the lifting effect of the bucket elevator. Moreover, the uneven feeding amount causes the stability of the buckets during the lifting process to decrease. Especially when the feeding amount suddenly increases, it causes an excessive load on the power system and transmission mechanism of the elevator. This not only may cause equipment failures or shutdowns, seriously affecting the continuity of the production line, but also may cause irreversible damage to the service life of the equipment. Therefore, these problems are not conducive to the normal use and efficiency improvement of the bucket elevator and need to be solved urgently. Summary of the Utility Model

[0018] Through the above technical solution, the piston rod of the second cylinder drives the T-shaped block to move synchronously.

[0019] The beneficial effects of the present utility model:

[0020] 1. The piston rod of the first cylinder pushes the connecting block to drive the pusher block to move, so that the capacity slot is located at the lower end of the feed hopper. By rotating the rocker to drive the screw rod to rotate, the screw rod pushes the fixed block to drive the L-shaped adjusting block to slide, so as to adjust the capacity inside the capacity slot. After adjusting to the required single-feed capacity, the materials to be lifted are conveyed into the feed hopper through the feed hopper. At this time, the materials need to be conveyed into the capacity slot once. Then, the piston rod of the first cylinder pushes the pusher block to move from left to right, so that the materials on the top surface of the pusher block are blocked by the baffle, and the materials inside the capacity slot slide along the inner wall of the feed box. When continuously moving above the triangular block, the materials inside the capacity slot fall onto the top surface of the triangular block and slide to the lower end, and the larger-sized materials are crushed by the crushing component. The crushed materials slide from the top surface of the triangular block and the top surface of the C-shaped guide block into the feed pipe and are conveyed into the bucket elevator body, completing the quantitative feeding of the materials of the bucket elevator body. After the conveying is completed, the pusher block returns to the initial position, enabling the materials to continuously and stably enter the capacity slot, thereby realizing the continuous quantitative conveying of the materials, improving the accuracy of material feeding, making the lifting and conveying of the bucket elevator body more efficient and reliable, reducing the damage to the bucket elevator body caused by excessive or unstable feeding, effectively protecting the integrity of the equipment. In the long run, this quantitative feeding method helps to extend the service life of the bucket elevator body and provides a strong guarantee for the stable operation of the equipment.

[0021] 2. By the screw rod pushing the fixed block to drive the L-shaped adjusting block to slide, the convenient adjustment of the capacity of the capacity slot on the pusher block is realized, making the adjustment of the material feeding amount flexible and rapid, adapting to the changes of different production requirements. At the same time, it also improves the stability and efficiency of the feeding of the bucket elevator body and facilitates the feeding use of the bucket elevator body.

[0022] 3. In the present utility model, for the possible larger particles in the materials, the piston rod of the second cylinder drives the T-shaped block to move synchronously, so that the T-shaped block drives the slider to slide along the trapezoidal through slot, and the rotating shaft and the crushing roller move synchronously, so as to adjust an appropriate gap between the outer wall of the crushing roller and the triangular block. The quantitatively conveyed materials slide between the crushing roller and the triangular block. When the larger-sized materials are difficult to pass through, the output shaft of the motor drives the rotating shaft to rotate, so that the crushing roller squeezes and crushes the larger-sized materials through the triangular block. The crushed materials slide along the triangular block to the lower part and enter the feed pipe, reducing the occurrence of blockage of the larger-sized materials during feeding, improving the feeding effect, reducing the possibility of the larger-sized materials entering the bucket elevator body, thereby reducing the potential impact on the bucket elevator body and further improving the convenience and stability of feeding.

[0023] 4. The design of the trapezoidal through - slot effectively shortens the residence time of the splashing materials therein, facilitating the rapid discharge of the materials inside the trapezoidal through - slot. This not only reduces the accumulation of materials in the trapezoidal through - slot but also decreases the obstruction of the materials to the movement of the slider, ensuring the smoothness of the slider during the adjustment process and contributing to maintaining a stable feeding state.

[0031] Embodiment 1

[0032] As Figure 1 , Figure 2 and Figure 3As shown in the figure, this embodiment provides a feeding device for a bucket elevator, which includes a bucket elevator body 1. The lower left end of the bucket elevator body 1 is connected to a feeding pipe 2. The upper end of the feeding pipe 2 is connected to a feeding box 3. The top surface of the feeding box 3 is connected to a feeding hopper 4. A stopper 401 is fixedly connected to the right end of the bottom surface of the feeding hopper 4. A support block 5 is fixedly connected to the bottom surface of the left end of the feeding box 3. A pushing block 6 is slidably connected to the left end of the feeding box 3. The pushing block 6 is slidably connected to the inner wall of the left end of the feeding box 3. An installation frame 7 is fixedly connected to the left wall of the support block 5. A first cylinder 8 is installed on the top surface of the installation frame 7 through an installation seat. A connecting block 601 is fixedly connected to the bottom surface of the left end of the pushing block 6. The piston rod of the first cylinder 8 is fixedly connected to the left wall of the connecting block 601. The connecting block 601 is slidably connected to the top surface of the installation frame 7. A capacity groove 9 is formed at the right end of the pushing block 6. An L-shaped adjusting block 10 is slidably connected to the pushing block 6. A crushing assembly 11 is provided inside the right end of the feeding box 3.

[0033] The bottom surface of the stopper 401 is slidably connected to the top surface of the pushing block 6. The right end of the L-shaped adjusting block 10 is located inside the capacity groove 9. The left end of the L-shaped adjusting block 10 penetrates through the left end of the pushing block 6 and extends to the outside. A fixing block 1001 is fixedly connected to the bottom surface of the left end of the L-shaped adjusting block 10. A lead screw 1002 is threadedly connected to the fixing block 1001 through a threaded hole. A rocker 1003 is fixedly connected to the lead screw 1002. One end of the lead screw 1002 is sleeved on the left end of the pushing block 6, and one end of the lead screw 1002 is rotatably connected to the pushing block 6. By rotating the rocker 1003 to drive the lead screw 1002 to rotate, the lead screw 1002 pushes the fixing block 1001 to drive the L-shaped adjusting block 10 to slide, so as to adjust the capacity inside the capacity groove 9.

[0034] A triangular block 12 is fixedly connected to the inner wall of the middle part of the feeding box 3. A C-shaped guiding block 13 is fixedly connected to the inner wall of the right end of the feeding box 3. The edge of the C-shaped guiding block 13 is higher than the middle part. The materials inside the capacity groove 9 fall onto the top surface of the triangular block 12 and slide to the lower end, and the crushing assembly 11 crushes the materials with larger sizes. The crushed materials slide from the top surface of the triangular block 12 and the top surface of the C-shaped guiding block 13 into the feeding pipe 2.

[0035] When the bucket elevator body 1 is used for feeding, first, the piston rod of the first cylinder 8 pushes the connecting block 601 to drive the pushing block 6 to move, so that the capacity tank 9 is located at the lower end of the feeding hopper 4. The rotating rocker 1003 drives the screw rod 1002 to rotate, and the screw rod 1002 pushes the fixed block 1001 to drive the L-shaped adjusting block 10 to slide, so as to adjust the capacity inside the capacity tank 9. After adjusting to the required single feeding capacity, the material to be lifted is conveyed into the feeding hopper 4 through the feeding hopper 4. At this time, the material needs to be conveyed into the capacity tank 9 once. Then, the piston rod of the first cylinder 8 pushes the pushing block 6 to move from left to right, so that the material on the top surface of the pushing block 6 is blocked by the baffle 401, and the material inside the capacity tank 9 slides along the inner wall of the feeding box 3. When it continuously moves above the triangular block 12, the material inside the capacity tank 9 falls onto the top surface of the triangular block 12 and slides to the lower end, and the larger-sized material is crushed by the crushing assembly 11. The crushed material slides from the top surface of the triangular block 12 and the top surface of the C-shaped guiding block 13 into the feeding pipe 2 and is conveyed into the bucket elevator body 1, completing the quantitative feeding of the material of the bucket elevator body 1;

[0036] After the conveying is completed, the pushing block 6 returns to the initial position, enabling the material to continuously and stably enter the capacity tank 9, thereby realizing the continuous quantitative conveying of the material, improving the accuracy of material feeding, making the lifting and conveying of the bucket elevator body 1 more efficient and reliable, reducing the damage to the bucket elevator body 1 caused by excessive or unstable feeding, effectively protecting the integrity of the equipment. In the long run, this quantitative feeding method helps to extend the service life of the bucket elevator body 1 and provides a strong guarantee for the stable operation of the equipment.

[0037] By pushing the fixed block 1001 with the screw rod 1002 to drive the L-shaped adjusting block 10 to slide, the capacity of the capacity tank 9 on the pushing block 6 can be conveniently adjusted, making the adjustment of the material feeding amount flexible and fast, adapting to the changes in different production requirements. At the same time, it also improves the stability and efficiency of the feeding of the bucket elevator body 1 and facilitates the feeding use of the bucket elevator body 1.

[0038] Embodiment 2

The crushing roller 1101 is located on the right side of the triangular block 12. The crushing roller 1101 is in clearance fit with the top surface of the triangular block 12. A rotating shaft 1102 is fixedly connected to the middle of the crushing roller 1101. Trapezoidal through grooves 1103 are formed in the front and rear walls of the feeding box 3. A sliding block 1104 is slidably connected inside the trapezoidal through groove 1103. The sliding block 1104 is sleeved on the rotating shaft 1102. The rotating shaft 1102 is rotatably connected to the sliding block 1104. A T-shaped block 1105 is fixedly connected to the outer wall of the sliding block 1104. Both ends of the rotating shaft 1102 are rotatably connected to the T-shaped block 1105. The inner wall of the T-shaped block 1105 is slidably connected to the outer wall of the feeding box 3; the T-shaped block 1105 drives the sliding block 1104 to slide along the trapezoidal through groove 1103, and the rotating shaft 1102 and the crushing roller 1101 move synchronously.

[0040] A motor 1107 is installed on one of the T-shaped blocks 1105 through a mounting seat. The output shaft of the motor 1107 is coaxially connected to the rotating shaft 1102; the rotating shaft 1102 is driven to rotate by the output shaft of the motor 1107, so that the crushing roller 1101 squeezes and crushes larger-sized materials through the triangular block 12.

[0041] Two second cylinders 1106 are symmetrically installed on the outer wall of the lower end of the feeding box 3 through front mounting seats. The piston rod of the second cylinder 1106 is fixedly connected to the lower side wall of the T-shaped block 1105; the piston rod of the second cylinder 1106 drives the T-shaped block 1105 to move synchronously.

When the larger-sized materials are difficult to pass through, the rotating shaft 1102 is driven to rotate by the output shaft of the motor 1107, so that the crushing roller 1101 squeezes and crushes the larger-sized materials through the triangular block 12, so that the crushed materials slide along the triangular block 12 to the lower part and enter the inside of the feeding pipe 2, reducing the occurrence of blockage of larger-sized materials during feeding, improving the feeding effect, reducing the possibility of larger-sized materials entering the bucket elevator body 1, thereby reducing the potential impact on the bucket elevator body 1, and further improving the convenience and stability of feeding;

[0043] The design of the trapezoidal through groove 1103 effectively shortens the residence time of the splashing materials therein, facilitating the rapid discharge of the materials inside the trapezoidal through groove 1103. This not only reduces the accumulation of materials in the trapezoidal through groove 1103, but also reduces the obstruction of the movement of the slider 1104 by the materials, ensuring the smoothness of the slider 1104 during the adjustment process and contributing to maintaining a stable feeding state.
