Description

Technical Field

[0001] This utility model is a TD type belt bucket elevator correction roller, belonging to the field of bucket elevators. Background Technology

[0002] The TD-type bucket elevator, also known as a belt elevator, consists of head and tail rollers, a traction conveyor belt, buckets, a screw, inlet and outlet ports, a casing, a motor, and a reducer. It is widely used for conveying powdery, granular, and small lump materials with low or no abrasiveness. When discussing belt conveyors, a crucial technical issue that cannot be ignored is "belt deviation correction." The main cause of conveyor belt deviation is uneven force distribution at both ends of the belt. Various factors can contribute to this uneven force distribution, such as uneven material mass distribution, fluctuations in the feed rate from the feeder, or changes in the verticality and parallelism of the head and tail rollers.

[0003] Traditional bucket elevator correction methods mainly employ drum rollers, utilizing centripetal force to achieve a certain degree of self-correction, or adding a screw adjustment device at the tail roller. However, due to prolonged operation, friction between the conveyor belt and the roller's center causes wear and depression in the coating, resulting in loss of belt correction capability. Screw adjustment devices require manual adjustment after observing belt deviation, but because the conveyor belt is sealed within the housing, deviation is difficult to detect. Even slight delays can cause wear between the conveyor belt's sides and the machine casing, significantly impacting the conveyor belt's lifespan and stability. Therefore, this invention proposes a TD-type belt-type bucket elevator correction roller. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a TD type belt bucket elevator correction roller.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A TD-type belt bucket elevator correction roller includes a belt bucket elevator body, which has a conveyor belt and a frame for mounting the conveyor belt. A side correction roller assembly is mounted on the frame. The side correction roller assembly includes an adjusting rod assembly, a mounting base, and a roller assembly. The roller assembly includes a stainless steel shell with bearings at both ends inside the shell. A roller shaft passes through the bearings and extends out of the shell at both ends. A mounting base is installed at both ends of the roller shaft. The adjusting rod assembly includes a threaded rod. The frame has a through-hole for the rod to pass through. A U-shaped frame is also mounted on the outer side of the frame, and a locking element with a locking rod is matched on the U-shaped frame.

[0007] Furthermore, the outer shell is made of stainless steel, the mounting bases are all U-shaped frames, the two ends of the roller shaft are plate-shaped and pass into the corresponding mounting bases, and the two ends of the roller shaft and the mounting bases are provided with mounting thread holes.

[0008] Furthermore, the U-shaped frame has a secondary through-hole for the pull rod to pass through, and the locking components include an outer nut and an inner nut.

[0009] Furthermore, both the outer nut and the inner nut are threaded onto the tie rod, with the inner nut tightly against the inner side of the U-shaped frame and the outer nut tightly against the outer side of the U-shaped frame.

[0010] Furthermore, a collar one is fixed to the outer end of the mounting base facing the frame with screws, and a collar two is provided on one side of the collar one. The collar two is fixed to the inner side of the frame with screws. A telescopic corrugated tube one is provided between the collar one and the collar two, and the pull rod is sleeved in the corrugated tube one.

[0011] Furthermore, a collar three is fixed to the outer end of the frame with screws, a collar four is provided on one side of the collar three, and a telescopic corrugated pipe two is provided between the collar four and the collar three, with the pull rod sleeved inside the corrugated pipe two.

[0012] Furthermore, a collar five is fixed to the outer side of the U-shaped frame with screws, and a collar six is ​​provided on one side of the collar five. A telescopic corrugated tube three is provided between the collar six and the collar five. The inner ring diameter of the collar six matches the diameter of the pull rod, and the collar six is ​​fitted onto the pull rod.

[0013] Furthermore, multiple positioning plates are fixedly provided on the collar six, and the positioning plates are fixed to the outer surface of the pull rod with screws.

[0014] The beneficial effects of this utility model are:

[0015] The side guide roller contacts both sides of the conveyor belt through its outer shell, improving the smoothness of the conveyor belt. The outer shell is made of stainless steel to improve the wear resistance of this component. Holes are drilled on both sides of the shell, that is, through holes are opened. The U-shaped frame is welded to the outside of the frame. The secondary through holes on the U-shaped frame correspond to the through holes. The tie rod passes out from the inside of the frame, and the tie rod is fixed to the U-shaped frame on the outside with locking devices, thus completing the fixation of the side guide roller assembly.

[0016] Because the roller used in this invention, that is, the outer shell, is made of stainless steel, the wear resistance of the device is improved, thereby extending the service life of the device. In addition, the use of the mounting base as the fixing part between the outer shell and the pull rod makes the device easy to replace. The pull rod and the U-shaped frame are fixed with locking parts, so it has the advantage of being adjustable.

[0017] Two screw mounting holes are pre-drilled on each side of the machine housing at the misalignment point. The conveyor belt must be positioned between the two holes. The mounting plate holes are then aligned with the machine housing holes to ensure concentricity. The mounting plate is then welded securely. The opening direction of the base plate can be adjusted according to the site conditions to facilitate tightening the nuts later. The tie rod is pre-connected to the roller and secured with a cotter pin. The tie rod then extends outward from inside the frame, with locking components installed on it to form a top screw structure for easy adjustment of the roller later. The same operation is performed on both sides of the conveyor belt housing. At this point, the installation of the correction roller is complete.

[0018] Uneven force on the conveyor belt causes it to deviate at the head or tail roller. To correct this, a through-hole is made at a suitable location on the frame near the head or tail of the machine, and a U-shaped frame is welded on. After installing the side guide correction roller assembly according to the steps, the distance between the roller assembly and the frame is adjusted using a tie rod to control the conveyor belt correction range. Once the conveyor belt deviates and comes into contact with the correction device, the roller assembly applies a reaction force to the conveyor belt, thus correcting the deviation.

Detailed Implementation

[0025] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-3 This utility model provides a TD type belt bucket elevator correction roller, including a belt bucket elevator body, the belt bucket elevator body having a conveyor belt 1 and a frame 2 for mounting the conveyor belt 1. A side correction roller assembly is mounted on the frame 2. The side correction roller assembly includes an adjusting rod assembly, a mounting base 3, and a roller assembly. The roller assembly includes a stainless steel shell 4, with bearings 5 ​​at both ends inside the shell 4. A roller shaft 6 passes through the bearings 5, and both ends of the roller shaft 6 extend out of the shell 4. A mounting base 3 is mounted on both ends of the roller shaft 6. The adjusting rod assembly includes a threaded rod 7. The frame 2 has a through-hole 8 for the rod 7 to pass through. A U-shaped frame 9 is also mounted on the outer side of the frame 2, and a locking element for locking the rod 7 is matched on the U-shaped frame 9.

[0027] See Figure 3 The outer shell 4 is made of stainless steel, and the mounting bases 3 are all U-shaped frames. The two ends of the roller shaft 6 are plate-shaped and pass through the corresponding mounting bases 3. The two ends of the roller shaft 6 and the mounting bases 3 are provided with mounting threaded holes. The installation threaded holes ensure that the mounting bases 3 and the two ends of the roller shaft 6 can be detachably connected, and the roller assembly is also easy to disassemble and replace in the future.

[0028] See Figure 1 The U-shaped frame 9 has a secondary through-hole 10 for the pull rod 7 to pass through. The locking components include an outer nut 11 and an inner nut 12. Both the outer nut 11 and the inner nut 12 are threaded onto the pull rod 7. The inner nut 12 is close to the inner side of the U-shaped frame 9, and the outer nut 11 is close to the outer side of the U-shaped frame 9. The outer nut 11 and the inner nut 12 are threaded onto the pull rod 7. At this time, the inner nut 12 is close to the inner side of the U-shaped frame 9, and the outer nut 11 is close to the outer side of the U-shaped frame 9, thus fixing the pull rod and effectively ensuring the adjustment of the eccentric roller.

[0029] See Figure 4A first collar 13 is fixed to the outer end of the mounting base 3 facing the frame 2 with screws. A second collar 14 is provided on one side of the first collar 13. The second collar 14 is fixed to the inner side of the frame 2 with screws. A telescopic corrugated tube 15 is provided between the first collar 13 and the second collar 14. The pull rod 7 is sleeved in the corrugated tube 15. A third collar 16 is fixed to the outer end of the frame 2 with screws. A fourth collar 17 is provided on one side of the third collar 16. A telescopic corrugated tube 28 is provided between the fourth collar 17 and the third collar 16. The pull rod 7 is sleeved in the corrugated tube 28. A fifth collar 19 is fixed to the outer side of the U-shaped frame 9 with screws. A sixth collar 20 is provided on one side of the fifth collar 19. A telescopic corrugated tube 21 is provided between the sixth collar 20 and the fifth collar 19. The inner ring diameter matches the diameter of the pull rod 7. The collar 6 20 is fitted onto the pull rod 7. Multiple positioning pieces 22 are fixed on the collar 6 20. The positioning pieces 22 are fixed to the outer surface of the pull rod 7 with screws. The collar 1 13, collar 2 14, collar 4 17, collar 3 16, and collar 5 19 are fixed separately with screws. The collar 5 19 is fixed to the outer surface of the pull rod 7 by the positioning pieces 22. Therefore, the corrugated pipe 3 21, corrugated pipe 2 18, and telescopic corrugated pipe 1 15 wrap around the pull rod to prevent dust from sticking to the outer thread of the pull rod. Because it is difficult to avoid these impurities sticking to the pull rod when conveying powdery, granular, and small block materials with no or little abrasiveness, this protects the pull rod and prevents it from being used normally later, which would cause installation inconvenience.

[0030] In use, the outer shell 4 of the side guide roller contacts both sides of the conveyor belt 1 to improve the stability of the conveyor belt. The outer shell 4 is made of stainless steel to improve the wear resistance of this component. Holes are drilled on both sides of the shell, that is, through holes 8 are opened. The U-shaped frame 9 is welded to the outside of the frame. The secondary through holes 10 on the U-shaped frame 9 correspond to the through holes 8. The pull rod 7 passes through the inside of the frame 2 and is fixed to the U-shaped frame 9 with locking parts on the outside, thus completing the fixation of the side guide roller assembly. Since the roller, that is, the outer shell 4, of this utility model is made of stainless steel, the wear resistance of the device is improved, thereby extending the service life of the device. And the mounting base 3 is used as the fixing part between the outer shell 4 and the pull rod, so the device has the advantage of easy replacement. The pull rod and the U-shaped frame 9 are fixed with locking parts, so it has the advantage of adjustment. By pre-drilling two screw mounting holes on each side of the shell at the deviation part of the machine body, the conveyor belt must be in In the middle of the two holes, align the holes on the mounting plate with the holes on the machine housing to ensure concentricity. Then weld the mounting plate firmly. The opening direction of the base plate can be adjusted according to the site conditions to facilitate tightening the nuts later. After connecting the tie rod and the roller in advance, fix it with a cotter pin. Then, the tie rod extends outward from inside the frame 2. Locking parts are arranged on the tie rod to form a top screw structure, which facilitates the adjustment of the roller later. Perform the same operation on both sides of the housing of the conveyor belt 1. At this point, the installation of the correction roller is completed. Uneven force on the conveyor belt causes the conveyor belt to run off-center at the head or tail roller. Open the through hole 8 at a suitable position on the frame 2 near the head or tail of the machine, and then weld the U-shaped frame 9. After installing the side guard correction roller assembly according to the steps, use the tie rod 7 to adjust the distance between the roller assembly and the frame 2 to control the correction range of the conveyor belt 1. Once the conveyor belt 1 runs off-center and contacts the correction device, the roller assembly applies a reaction force to the conveyor belt 1 to correct the off-center movement.

[0031] Specifically, the belt bucket elevator is a publicly available structure, which will not be described in detail here, and its drive components are all existing technologies.

[0032] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
