Description

Technical Field

[0001] This utility model relates to the field of bucket elevator technology, and in particular to a bucket elevator with a cleaning structure. Background Technology

[0002] A bucket elevator is a continuous conveying machine that vertically lifts materials using a series of buckets evenly fixed to a traction component. When the bucket elevator is working, the buckets scoop up material from a storage tank below, lift it to the top via a conveyor belt or chain plate, pass it over a top wheel, and then tilt downwards, dumping the material into a receiving trough. Bucket elevators are commonly used at the junctions of various workstations in automated production lines. Taking the raw material crushing process in the initial processing of natural rubber as an example, after the natural rubber raw material is initially crushed and kneaded, it falls into a washing tank for cleaning. Before entering subsequent workstations, a bucket elevator is needed to scoop up the natural rubber raw material from the washing tank and transport it to secondary kneading or granulation equipment. In the operation of the aforementioned bucket elevator, hollow buckets are commonly used. Since natural rubber tends to stick to the buckets in strips during the initial kneading process, there is a risk that the material may not be completely discharged during the throwing process, especially at the bottom of the buckets. To address the cleaning of the bottom of the hopper, the existing Chinese patent publication number CN215363479U discloses a bucket elevator with a cleaning mechanism, which uses a rotatable high-pressure air gun to blow air for cleaning the inside and bottom of the hopper.

[0003] However, the above technical solutions cannot solve the problem of rubber residue on natural rubber raw materials, especially when the rubber material is in the form of flocculent strands, the high-pressure air gun cannot clean the residue within a limited working time. Utility Model Content

[0004] The purpose of this invention is to solve the problem of difficult-to-clean adhesive residue at the bottom of the hopper in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bucket elevator with a cleaning structure includes a frame, a conveying assembly within the frame, a plurality of buckets on the conveying assembly, a motor on the frame, the output shaft of the motor connected to the conveying assembly, the motor located on the frame, and electrically connected to an external power source. A cleaning assembly is also located within the frame. The cleaning assembly includes a first connecting rod located within the frame, a first rod on the first connecting rod, a second rod on the first connecting rod, a torsion spring between the second rod and the first rod, a roller on the first rod, a cleaning roller on the second rod, a second connecting rod within the frame, and a telescopic rod on the second connecting rod connected to the second rod.

[0007] Preferably, the first rod is provided with a first limiting block, the second rod is provided with a second limiting block, and the two ends of the torsion spring abut against the first limiting block and the second limiting block respectively.

[0008] Preferably, the outer surface of the cleaning roller is provided with a plurality of protrusions, the protrusions being J-shaped.

[0009] Preferably, a first drive wheel is provided on one side of the roller, a second drive wheel is provided on one side of the sweeping roller, and a first drive belt is provided between the first drive wheel and the second drive wheel.

[0010] Preferably, the frame is provided with a tensioning assembly, which includes a mounting box located inside the frame. The mounting box contains a piston rod that is slidably connected to the mounting box. The mounting box contains a spring with one end abutting against the piston rod. One end of the piston rod is provided with a tensioning wheel connected to the piston rod and abutting against the transmission belt.

[0011] Preferably, the conveying assembly includes a plurality of sprockets, with chains connecting them to each other, and one drive wheel among the sprockets is connected to the output shaft of the motor.

[0012] Preferably, a transmission assembly is provided between the drive wheel and the motor. The transmission assembly includes a third transmission wheel and a fourth transmission wheel. The third transmission wheel is connected to the drive wheel, and the fourth transmission wheel is connected to the output shaft of the motor. A second transmission belt is provided between the third transmission wheel and the fourth transmission wheel.

[0013] Preferably, the bottom of the frame is provided with a return groove.

[0014] The beneficial effects proposed by this utility model are as follows:

[0015] The bucket elevator operates on one side of the cleaning pool, and the frame is placed on the foundation on the same side of the cleaning pool. When the motor starts, it drives the conveying assembly, causing the buckets to circulate on the conveying device. The buckets sequentially flow through the cleaning pool, scooping up natural rubber. After dumping the rubber to the next workstation, the buckets return from below the frame. When a bucket passes the cleaning assembly, its front end first contacts the roller. Upon contact, the roller experiences a lifting force from the bucket, causing the first rod to flip upwards. Under the action of the torsion spring, the angle between the second rod and the first rod decreases, causing the second rod to flip downwards. This causes the cleaning roller to move downwards from the frame, closer to the bucket. As the bucket passes the cleaning roller, it cleans the rubber adhering to the bucket, scraping it off and cleaning the bottom of the bucket. When the roller disengages from the hopper, the first rod returns to its original position. At this time, the torsion spring increases the angle between the first and second rods, causing the second rod to retract the cleaning roller back into the frame. This process occurs periodically as the hopper circulates. The cleaning structure is activated periodically by the periodic interaction between the roller and the hopper. Utilizing the cyclical flow of the hopper, the cleaning roller effectively removes the adhesive residue within the periodic intervals after scraping it off. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figures 1 to 6A bucket elevator with a cleaning structure is provided. The frame 1 contains a conveying assembly with several buckets 2. A motor 5 is mounted on the frame 1, its output shaft connected to the conveying assembly. The motor 5 is located on the frame 1 and electrically connected to an external power source. A cleaning assembly is also provided within the frame 1. The cleaning assembly includes a first connecting rod 9 located within the frame 1. A first rod 10 and a second rod 11 are mounted on the first connecting rod 9. A torsion spring 16 is provided between the second rod 11 and the first rod 10. A roller 13 is mounted on the first rod 10, and a cleaning roller 14 is mounted on the second rod 11. A second connecting rod 12 is also provided within the frame 1, with a telescopic rod 15 connected to the second rod 11. Specifically, the bucket elevator is arranged to work on one side of the cleaning pool, and the frame 1 is arranged on the foundation on one side of the cleaning pool. The motor 5 is started, driving the conveying assembly to run, and then the bucket 2 circulates on the conveying device. At this time, the bucket 2 flows through the cleaning pool in sequence, scooping up the natural rubber from the cleaning pool. After the bucket 2 pours the natural rubber to the next station, it flows back from under the frame 1. When the hopper 2 passes the cleaning assembly, the front end of the hopper 2 first contacts the roller 13. After the roller 13 contacts the hopper 2, it is subjected to a lifting force from the hopper 2. At this time, the first rod 10 flips upward. Under the action of the torsion spring 16, the angle formed between the second rod 11 and the first rod decreases, and the second rod 11 flips downward, causing the cleaning roller 14 to move downward towards the frame 1 and closer to the hopper 2. When the hopper 2 passes the cleaning roller 14, the cleaning roller 14 cleans the adhesive adhering to the hopper 2, scraping the adhesive off the hopper 2, thus cleaning the adhesive adhering to the bottom of the hopper 2. When the roller 13 disengages from the hopper 2, the first rod 10 returns to its original position. At this time, the torsion spring 16 increases the angle between the first rod 10 and the second rod 11, and the second rod 11 drives the cleaning roller 14 to retract into the frame 1. As the hopper 2 circulates, the cleaning component is activated periodically. The cleaning structure is activated periodically by the roller 13 and the hopper 2. The periodic circulation of the hopper 2 helps the cleaning roller 14 to discharge the adhesive within the periodic interval after scraping it off.

[0025] Specifically, the first rod 10 is provided with a first limiting block 24, and the second rod 11 is provided with a second limiting block 25. The two ends of the torsion spring 16 abut against the first limiting block 24 and the second limiting block 25, respectively. After the two ends of the torsion spring 16 abut against the first limiting block 24 and the second limiting block 25, it is beneficial to the stability of the torsion spring 16 during operation and reduces the risk of the torsion spring 16 detaching from the first rod 10 and the second rod 11.

[0026] Specifically, the outer surface of the cleaning roller 14 is provided with a plurality of protrusions 26, which are J-shaped. Since the adhesive coating on the hopper 2 is too long, the J-shaped protrusions 26 are provided. When the protrusions 26 roll over the adhesive coating, they can hook the adhesive coating out of the hopper 2, which helps to improve the cleaning efficiency of the cleaning roller 14. Simultaneously, as the cleaning roller 14 rotates, the J-shaped protrusions 26 improve the throwing efficiency by using centrifugal force to detach the adhesive coating from the protrusions 26.

[0027] Specifically, a first drive wheel 17 is provided on one side of the roller 13, and a second drive wheel 19 is provided on one side of the sweeping roller 14. A first drive belt 18 is provided between the first drive wheel 17 and the second drive wheel 19. In order to improve the rotation efficiency of the sweeping roller 14 and improve the cleaning effect, the roller 13 is the first to contact the hopper 2 and rotate during the operation of the cleaning assembly. Therefore, the rotation of the roller 13, through the connection of the first drive belt 18, the first drive wheel 17 and the second drive wheel 19, can be used to make the sweeping roller 14 start to rotate at the same time as the roller 13 rotates. When the sweeping roller 14 contacts the cleaning surface of the hopper 2, it can scrape off the glue immediately, thereby improving the cleaning efficiency.

[0028] Specifically, the frame 1 is equipped with a tensioning assembly, which includes a mounting box 20 located within the frame 1. A piston rod 21 is located within the mounting box 20 and is slidably connected to it. A spring 23 is also located within the mounting box 20, with one end abutting against the piston rod 21. A tensioning wheel 22 is located at one end of the piston rod 21 and is connected to it, abutting against the first transmission belt 18. The tensioning assembly acts on the first transmission belt 18. When the angle between the first rod 10 and the second rod 11 decreases, the linear distance between the first transmission wheel 17 and the second transmission wheel 19 shortens, thereby reducing the tension of the first transmission belt 18. At this time, the tensioning wheel 22, under the action of the spring 23, presses the first transmission belt 18, keeping the tension of the first transmission belt 18 in a balanced state during this process, maintaining the transmission stability of the first transmission wheel 17 and the second transmission wheel 19, and reducing the risk of the first transmission belt 18 coming off. Conversely, when the angle between the first rod 10 and the second rod 11 increases, the tension of the first transmission belt 18 increases, pushing the tensioning wheel 22 upward, and the piston rod 21 compresses the spring 23. In the above process, since the tensioning wheel 22 and the piston rod 21 are connected by a shaft, the tensioning wheel 22 rotates on the piston rod 21 around the shaft. When the first transmission belt 18 moves, the tensioning wheel 22 rotates along with it, and will not interfere with the normal operation of the first transmission belt 18 during the tensioning process.

[0029] Specifically, the conveying assembly includes several sprockets 7, with chains 8 connecting them. One drive wheel is located within each sprocket 7 and is connected to the output shaft of the motor 5. The sprockets 7 are located within the frame 1, and the chains 8 are wound around them and connected to the hoppers 2. When the drive wheel is driven to rotate by the motor 5, the sprockets 7 rotate synchronously, driving the hoppers 2 to circulate on the frame 1 via the chains 8, thus achieving the cyclical operation of the hoppers 2 and ensuring the normal operation of the elevator.

[0030] Specifically, a transmission assembly is provided between the drive wheel and the motor 5. This transmission assembly includes a third transmission wheel 3 and a fourth transmission wheel 27. The third transmission wheel 3 is connected to the drive wheel, and the fourth transmission wheel 27 is connected to the output shaft of the motor 5. A second transmission belt 4 is provided between the third transmission wheel 3 and the fourth transmission wheel 27. The motor 5 and the drive wheel are connected through this transmission assembly. When the output shaft of the motor 5 rotates, the fourth transmission wheel 27 on the output shaft rotates synchronously. Through the transmission of the second transmission belt 4, the third transmission wheel 3 rotates, thereby driving the drive wheel to start. This transmission assembly reduces the space required for the bucket elevator during installation, improves the rationality of the equipment structure, and facilitates later maintenance.

[0031] Specifically, the bottom of the frame 1 is provided with a return trough 6. The return trough 6 is located at the bottom of the frame 1. When the hopper 2 is driven by the conveying component to return, it will pass through the return trough 6. The return trough 6 can collect and recycle the rubber residue cleaned by the cleaning component into the cleaning tank. It can also collect the water filtered from the hopper 2 when the hopper 2 scoops up natural rubber and return it to the cleaning tank. This reduces the pollution of the equipment site during the operation of the bucket elevator, and realizes the recycling of rubber raw materials and water, reducing the production costs caused by the waste of raw materials and water.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
