[0002] Coal powder, as an important product of coal processing, is widely used in power, chemical industry, metallurgy and other industries. Its fine powder form makes it necessary to have high adaptability and flexibility of equipment during storage, transportation and processing. As a key link in the coal powder processing production line, the discharge hopper is responsible for loading, transferring and discharging coal powder. Its design rationality and performance stability have a decisive influence on the processing efficiency and safety of coal powder.

[0003] In the coal powder processing industry, discharge hoppers are widely used. However, most of the traditional discharge hoppers only have the basic function of carrying coal powder and have relatively simple structures, which cannot be adjusted in height. This limitation brings many inconveniences in actual production. Especially when discharging between coal powder storage equipment or processing equipment of different heights, the traditional discharge hopper cannot be adjusted in height and often needs to rely on additional lifting equipment or manual handling, which is not only cumbersome to operate but also inefficient. In addition, the misalignment of the discharge opening and the receiving equipment during discharging often affects the accuracy of discharging. At the same time, the inconvenience of discharging also increases the time cost and labor cost in the production process, reducing the overall processing efficiency. SUMMARY

[0004] The utility model aims to provide a liftable coal powder processing discharge hopper, which solves the problem of the traditional discharge hopper that cannot be adjusted in height and often needs to rely on additional lifting equipment or manual handling when discharging between coal powder storage equipment or processing equipment of different heights, which is not only cumbersome to operate but also inefficient.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0023] In the coal processing production line, when the liftable coal processing discharge hopper is needed to unload, first, the operator will start the first hydraulic cylinder 3. The first hydraulic cylinder 3 is fixedly connected with the bottom of the bearing plate 2 through its output shaft, so when the first hydraulic cylinder 3 is started, the extension and retraction movement of its output shaft will drive the bearing plate 2 to slide up and down inside the frame body 1. At this time, the hopper 5 on the bearing plate 2 will also rise or fall. The operator will lower the hopper 5 to the lowest position to easily put the coal powder needed into the hopper 5. After the coal powder is put into the hopper 5, according to actual needs, if the position receiving the coal powder has a certain height, the operator can start the first hydraulic cylinder 3 again to make its output shaft extend, thereby driving the bearing plate 2 and the hopper 5 to rise until the discharge port of the hopper 5 reaches the height suitable for the receiving equipment. Next, the coal powder unloading operation is carried out. Before unloading, the operator needs to extend the adjusting frame 7. The adjusting frame 7 is slidingly connected with the outside of the discharge frame 6, and its extension length can be adjusted according to actual needs. The operator extends the adjusting frame 7 to the top of the unloading position and fixes the adjusting frame 7 to ensure its stability during unloading. Finally, the operator starts the second hydraulic cylinder 12. The output shaft of the second hydraulic cylinder 12 penetrates the bearing plate 2 and is rotatably connected with the sliding block 13 on one side of the bottom of the hopper 5 through a pin shaft. When the second hydraulic cylinder 12 is started, the extension and retraction movement of its output shaft will drive the sliding block 13 to slide on the bottom of the hopper 5, thereby making the hopper 5 tilt, wherein the hopper 5 rotates and tilts along the pin shaft in the support frame 4. After the hopper 5 tilts, the coal powder in it will be unloaded to the position needed through the discharge frame 6 and the adjusting frame 7.

[0024] Further, the top of the frame body 1 is fixedly connected with a top plate 8, and the bottom of the top plate 8 is fixedly connected with the inner bottom of the frame body 1 on both sides, and a slide rod 9 is arranged on each side, and a slide sleeve 10 is sleeved on one end of each slide rod 9, and one side of each slide sleeve 10 is fixedly connected with one side of the bearing plate 2. When the first hydraulic cylinder 3 drives the bearing plate 2 to slide up and down inside the frame body 1, the slide sleeve 10 will slide along the slide rod 9 to provide stable guidance and support for the bearing plate 2, thereby enhancing the stability of the bearing plate 2 during lifting, preventing the bearing plate 2 from deviating or tilting due to uneven force or external force, and ensuring the accuracy of coal powder unloading.

[0025] Further, the top of the adjusting frame 7 is fixedly connected with the connecting plates 17 on both sides, one side of the two connecting plates 17 is fixedly connected with the sliding blocks 15, and the two sliding blocks 15 are slidably connected with the top of the discharge frame 6 through the sliding grooves 16. When the adjusting frame 7 extends or shrinks, the connecting plates 17 drive the sliding blocks 15 to slide in the sliding grooves 16, so that the relative movement between the adjusting frame 7 and the discharge frame 6 is realized, the extension and contraction of the adjusting frame 7 are more smooth and stable, the adaptability and flexibility of the discharge hopper are improved, and the adjustment according to the needs of different discharge positions is facilitated.

[0026] Further, the top of the two connecting plates 17 is provided with the insertion rod 18, one end of the two insertion rods 18 penetrates through the two connecting plates 17 respectively, and the top of the discharge frame 6 is provided with a plurality of insertion grooves 19 matched with the insertion rods 18. After the adjusting frame 7 extends to the required position, the operator can insert the insertion rod 18 into the corresponding insertion groove 19 to limit and fix the adjusting frame 7, so as to enhance the stability of the adjusting frame 7 during the discharging process, prevent the adjusting frame 7 from moving or shaking due to the impact of coal powder or external force, and ensure the smooth discharging.

[0027] Further, the bottom of the hopper 5 is provided with the sliding groove 14 on one side, and the sliding block 13 is slidably connected with the bottom of the hopper 5 through the sliding groove 14. When the second hydraulic oil cylinder 12 drives the sliding block 13 to slide on the bottom of the hopper 5, the sliding block 13 slides along the sliding groove 14, thereby driving the inclination of the hopper 5, so that the inclination of the hopper 5 is more smooth and stable, the efficiency and accuracy of discharging are improved, and the friction and wear between the hopper 5 and the supporting frame 4 during the inclination process are reduced.

[0028] Further, the bottom of the frame body 1 is fixedly connected with the universal self-locking wheels 11 at the four corners. When it is necessary to move the discharge hopper to different positions for discharging, the operator can push the frame body 1 to make the universal self-locking wheels 11 roll on the ground, so as to realize the easy movement of the discharge hopper.

[0029] In summary:

[0030] Firstly, the operator will start the first hydraulic oil cylinder 3. The first hydraulic oil cylinder 3 is fixedly connected with the bottom of the bearing plate 2 through its output shaft, so when the first hydraulic oil cylinder 3 is started, the extension and contraction movement of its output shaft will drive the bearing plate 2 to slide up and down inside the frame body 1. At this time, the top plate 8 fixedly connected with one side of the top of the frame body 1 and the slide rod 9 fixedly connected between the bottom of the top plate 8 and the inside bottom of the frame body 1 play a key role in guiding and supporting. The sliding sleeve 10 is sleeved on the slide rod 9 and is fixedly connected with one side of the bearing plate 2, when the bearing plate 2 slides up and down, the sliding sleeve 10 will slide along the slide rod 9, which enhances the stability of the bearing plate 2 during lifting, prevents deviation or inclination due to uneven stress or external force, and ensures the accuracy of the coal powder unloading. The hopper 5 on the bearing plate 2 will also rise or fall, the operator will lower the hopper 5 to the lowest position to easily put the coal powder needed into the hopper 5. After the coal powder is put into the hopper 5, according to the actual needs, if the position receiving the coal powder has a certain height, the operator can start the first hydraulic oil cylinder 3 again to make its output shaft extend, so as to drive the bearing plate 2 and the hopper 5 to rise until the discharge port of the hopper 5 reaches the height suitable for the receiving equipment. Next, the coal powder unloading operation is carried out. Before unloading, the operator needs to extend the adjusting frame 7. The adjusting frame 7 is slidingly connected with the outside of the discharge frame 6, the top of the adjusting frame 7 is fixedly connected with the connecting plate 17 on both sides, and the connecting plate 17 is fixedly connected with the sliding block 15 on one side. When the adjusting frame 7 extends or contracts, the connecting plate 17 will drive the sliding block 15 to slide in the sliding groove 16 on the top of the discharge frame 6, so as to realize the relative movement between the adjusting frame 7 and the discharge frame 6. The extension and contraction of the adjusting frame 7 are more smooth and stable, which improves the adaptability and flexibility of the discharge hopper, and facilitates adjustment according to the needs of different unloading positions. After the operator extends the adjusting frame 7 to the top of the unloading position, the inserting rod 18 on the top of the two connecting plates 17 is inserted into the corresponding inserting slot 19 opened on the top of the discharge frame 6 to limit and fix the adjusting frame 7. This design enhances the stability of the adjusting frame 7 during unloading, prevents movement or shaking due to coal powder impact or external force, and ensures smooth unloading. Finally, the operator starts the second hydraulic oil cylinder 12. The output shaft of the second hydraulic oil cylinder 12 penetrates the bearing plate 2 and is rotatably connected with the sliding block 13 on one side of the bottom of the hopper 5 through a pin shaft. The bottom of the hopper 5 is provided with a sliding groove 14, and the sliding block 13 is slidingly connected between the bottom of the hopper 5 and the sliding groove 14. When the second hydraulic oil cylinder 12 is started, the extension and contraction movement of its output shaft will drive the sliding block 13 to slide along the sliding groove 14 on the bottom of the hopper 5, so as to make the hopper 5 tilt. The hopper 5 tilts along the pin shaft in the support frame 4, and after tilting, the coal powder in it will be unloaded to the desired position through the discharge frame 6 and the adjusting frame 7.This design makes the tilting of the hopper 5 more smooth and stable, improves the efficiency and accuracy of unloading, and reduces the friction and wear between the hopper 5 and the support frame 4 during tilting. In addition, the four corners of the bottom of the frame body 1 are fixedly connected with universal self-locking wheels 11. When it is necessary to move the unloading hopper to different positions for unloading, the operator can push the frame body 1 so that the universal self-locking wheels 11 roll on the ground, thereby achieving easy movement of the unloading hopper. This design enhances the mobility and flexibility of the unloading hopper, facilitates unloading operations at different positions, and improves the overall efficiency of the coal powder processing production line.
