Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to a bucket elevator. Background Technology

[0002] Bucket elevators are devices that transport materials vertically or at an incline by having buckets circulate along a track. They are widely used in grain, mining, chemical and other fields. Most existing bucket elevators use a single speed drive for the buckets. In actual conveying, there is a problem that the empty stroke and the working stroke have the same speed. The empty stroke does not require precise position control, but the fixed speed leads to wasted time. The working stroke requires precise alignment with the loading and unloading ports. A single speed makes it difficult to achieve both "fast conveying" and "precise positioning", which can easily lead to problems such as loading deviation and leakage, and unloading position deviation. This not only reduces work efficiency but also affects conveying accuracy, making it difficult to meet the high requirements of material conveying scenarios. Utility Model Content

[0022] Reference Figure 1-3 The first transmission mechanism includes a hydraulic cylinder 9 and a push rod 6. A transmission plate 7 is slidably provided on the upper surface of the base plate 1 and on the side of the vertical shell 2 away from the movable shell 3. Two push rods 6 are provided on both sides of the transmission plate 7. One end of the push rod 6 is rotatably connected to the transmission plate 7 through a first rotating rod 8. The side of the push rod 6 away from the transmission plate 7 is rotatably connected to the corresponding slider 4 through a second rotating rod 5. The hydraulic cylinder 9 is fixedly provided on the upper surface of the base plate 1 and between the vertical shell 2 and the transmission plate 7. The piston rod end of the hydraulic cylinder 9 is fixedly connected to the transmission plate 7. Fixed tubes 10 are fixedly provided on both sides of the upper surface of the base plate 1 and on both sides of the hydraulic cylinder 9. A movable rod 11 is movably sleeved inside the fixed tube 10. One end of the movable rod 11 is fixedly connected to the transmission plate 7, so that the transmission plate 7 can move stably.

[0023] Reference Figure 1-3 The second transmission mechanism includes a lead screw 12 and a connecting block 14. The lead screw 12 is rotatably disposed inside one side of the movable shell 3. The connecting block 14 is threadedly sleeved on the wall of the lead screw 12. One side of the connecting block 14 is fixedly connected to the hopper 17. A first motor 25 is fixedly disposed on the upper surface of the movable shell 3. The output end of the first motor 25 is fixedly connected to one end of the lead screw 12. A vertical rod 13 is disposed parallel to one side of the lead screw 12. The two ends of the vertical rod 13 are fixedly connected to the corresponding inner walls of the movable shell 3. One side of the connecting block 14 is movably sleeved with the vertical rod 13, so that the connecting block 14 can slide stably.

[0024] Reference Figure 1-3The third transmission mechanism includes a turntable 19 and a movable frame 22. A limit block 21 is fixedly installed on the front outer wall of the hopper 17. A limit hole is opened on the side wall of the limit block 21. An L-shaped rod 24 is slidably sleeved inside the limit hole. One end of the L-shaped rod 24 is fixedly connected to the sealing plate 16. The movable frame 22 is fixedly installed at the other end of the L-shaped rod 24. The turntable 19 is located between the movable frame 22 and the hopper 17. A transmission rod 15 is rotatably sleeved in the middle of the hopper 17. One end of the transmission rod 15 is fixedly connected to the middle of the turntable 19. The side of the hopper 17 away from the turntable 19 is fixed. A second motor 18 is provided, and the output end of the second motor 18 is fixedly connected to one end of the transmission rod 15. A round pin 20 is eccentrically provided on the side of the turntable 19 near the movable frame 22. The front end of the round pin 20 passes through the corresponding movable frame 22. An anti-detachment ring 23 is fixedly sleeved on the end of the round pin 20 away from the turntable 19 to prevent the round pin 20 from slipping out of the movable frame 22 as much as possible. The longitudinal section of the limiting hole and the L-shaped rod 24 are both rectangular. The rod wall of the L-shaped rod 24 abuts against the inner wall of the limiting hole, so that the L-shaped rod 24 cannot rotate relative to the limiting hole, that is, it can slide stably in the limiting hole.

[0025] In this invention, the hopper 17 is initially in a low position. Material to be conveyed is first loaded into the hopper 17, and the sealing plate 16 abuts against the opening of the hopper 17 to prevent spillage. If it is necessary to quickly lift the hopper 17, the hydraulic cylinder 9 is activated. The piston rod of the hydraulic cylinder 9 retracts, pulling the transmission plate 7 towards the vertical shell 2. The movable rods 11 on both sides of the transmission plate 7 slide along the fixed tube 10, providing guidance and stability to the transmission plate 7. The transmission plate 7 drives the lower ends of the push rods 6 on both sides to move synchronously via the first rotating rod 8. The push rods 6 rotate around the first rotating rod 8 and the second rotating rod 5 towards verticality. The second rotating rod 5 pushes the slider 4 to slide upward along the strip opening of the vertical shell 2. The slider 4 drives the movable shell 3 to rise rapidly along the inner wall of the vertical shell 2. The movable shell 3 simultaneously drives the hopper 17 to rise rapidly to near the target height, reducing the wasted time during the idle stroke or the initial lifting stage and improving efficiency. When the hopper 17 approaches the target unloading position, and the position of the hopper 17 needs to be precisely adjusted to ensure conveying accuracy, the first motor 25 is started. The first motor 25 drives the lead screw 12 to rotate. Under the limiting action of the vertical rod 13, the connecting block 14 cannot rotate with the lead screw 12 and can only move vertically along the rod wall of the lead screw 12. Block 14 drives the hopper 17 to move slowly and precisely up and down relative to the movable shell 3 until the hopper 17 is precisely aligned with the discharge port, completing the precise adjustment in the two-stage movement to ensure conveying accuracy. During discharge, the second motor 18 is started, which drives the transmission rod 15 to rotate. The transmission rod 15 drives the turntable 19 to rotate synchronously. The round pin 20 on the turntable 19 rotates eccentrically with the turntable 19 and slides within the movable frame 22, pushing the movable frame 22 to move away from the hopper 17. The movable frame 22 drives the L-shaped rod 24 to slide along the limiting hole of the limiting block 21. The L-shaped rod 24 pulls the sealing plate 1. The material in hopper 17 is discharged from the opening of the hopper 17 after the material is discharged. After the material is discharged, the second motor 18 is started in reverse. The round pin 20 pushes the movable frame 22 in reverse. The L-shaped rod 24 drives the sealing plate 16 to reset and abut against the opening, closing the hopper 17. If the hopper 17 needs to return to the low position, the hydraulic cylinder 9 is started in reverse. The piston rod extends and pushes the transmission plate 7 to move. The push rod 6 rotates to tend to be horizontal, driving the movable shell 3 and the hopper 17 to quickly descend and reset, so as to carry out the next round of material conveying. The whole process is carried out through two-stage movement of "rapid lifting + precise adjustment", which takes into account both work efficiency and conveying accuracy.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
