Description

Technical Field

[0001] This utility model relates to the field of industrial production technology, and more specifically, it relates to a bulk material bucket elevator that is easy to adjust for feeding. Background Technology

[0002] In many industrial production processes, especially in bulk material handling and loading / unloading operations, bucket elevators are often used for loading and transporting materials. In order to improve operational efficiency and adapt to different types of materials, different models of buckets are sometimes required to complete the task.

[0003] However, current technology generally has a problem: different models of buckets often require complex disassembly and assembly operations. Each time the bucket is replaced, the operator needs to spend a lot of time on installation and debugging. This not only affects work efficiency, but also increases the complexity of manual operation, especially in scenarios where the bucket needs to be replaced frequently.

[0004] Therefore, in order to address the issue of rapid bucket replacement under different operational needs of bulk material bucket elevators, the market needs a technical solution that facilitates feed adjustment and rapid bucket replacement. In existing technologies, bucket replacement is usually achieved by fixing connecting parts or by disassembling a large number of components. This is not only cumbersome but also requires high operational skills, leading to increased training costs for operators and increased maintenance difficulty of production equipment.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a bulk material bucket elevator that is easy to adjust for feeding, and has the following beneficial effects:

[0018] 1. The beneficial effects of the lifting mechanism are reflected in its ability to efficiently drive the buckets to lift materials. The motor drives the drive wheel, which in turn drives the transmission wheel through the transmission chain, thus driving multiple buckets to smoothly scoop and lift materials. With the coordinated action of multiple buckets, this mechanism improves the efficiency of material handling and ensures the stability and continuity of operations. Compared with traditional bucket elevators, the design of this lifting mechanism makes the loading and transportation of bulk materials faster and more reliable, especially suitable for operating environments that require large-scale material handling. It avoids the complex process of manual adjustment and intervention, thereby effectively improving production efficiency.

[0019] 2. The benefits of the quick-installation mechanism are reflected in its ability to quickly install and disassemble the bucket, greatly facilitating the operation of the workers. The combination of the insertion rod and the pre-drilled hole in the bucket, and the insertion design of the fixing sleeve and the snap-fit ​​rod, make the bucket installation process simple and efficient. When the bucket needs to be disassembled, by rotating the rotating sleeve and pushing the push spring, the pressure ring releases the contact with the snap-fit ​​block, and the return spring pushes the snap-fit ​​block and snap-fit ​​rod to loosen, so the bucket can easily be removed from the fixed position. This greatly reduces the time and labor intensity required to change the bucket. This structure is particularly suitable for operation scenarios that require frequent replacement of different models of buckets, optimizing the flexibility and adaptability of the equipment, and improving the overall operation efficiency and production flexibility.

[0020] 3. The beneficial effects of the limiting mechanism are reflected in its precise limiting and positioning design, which ensures the stability and safety of the bucket installation. Through the cooperation of the limiting block and the rotating sleeve in the limiting mechanism, the bucket can be accurately positioned during installation, preventing the bucket from shifting or loosening. The setting of the unlocking hole and the limiting groove makes the limiting process smoother, avoiding excessive friction and jamming problems. Through the design of the return spring and the compression spring, the limiting mechanism also provides the necessary pressure and support force, ensuring that the bucket is always in a stable working state during use. In addition, this design of the limiting mechanism improves the safety of the bucket, preventing equipment failure or safety accidents that may be caused by the bucket loosening, thereby increasing the service life and reliability of the equipment.

[0032] Compression springs 24 are provided between the bottom surface of multiple sets of card blocks 13 and the inner wall of the fixing sleeve 10.

[0033] The compression spring 24 provides constant pressure, making the contact between the locking block 13 and the retaining sleeve 10 tighter, enhancing the friction between the retaining sleeve and the locking block, thereby improving the bucket's ability to maintain stability during operation and preventing loosening or displacement.

[0034] A compression spring 25 is connected to the top surface of the inner sleeve 10, and a push plate 26 is fixedly attached to the bottom end of the compression spring 25.

[0035] Each of the multiple card slots 14 has a clearance slot 27 at its top.

[0036] The design of the clearance groove 27 allows the locking block 13 to move freely within the locking groove 14, reducing friction between the locking groove and the locking block, making the installation and disassembly of the bucket smoother, avoiding jamming, and improving operating efficiency and accuracy.

[0037] The bottom surface of the connecting sleeve 18 is connected to a push spring 28. Multiple sets of push springs 28 are provided, and each set of the bottom end is connected to a connecting ring 29. The bottom surface of each set of connecting rings 29 is fixed with an arc-shaped slider 30. The top surface of the rotating sleeve 21 is provided with an annular groove 31, and the multiple sets of arc-shaped sliders 30 slide in the annular groove 31.

[0038] The cooperation between the push spring 28 and the arc-shaped slider 30 ensures that the connecting sleeve 18 can be smoothly adjusted in position during operation. The sliding of the arc-shaped slider 30 in the annular groove 31 reduces mechanical friction, making the whole structure more flexible and stable, improving the synergy between components, and enhancing the durability and stability of the system.

[0039] The bottom end of the snap rod 9 is provided with a positioning block 32, and the inner side of the fixing sleeve 10 is provided with a positioning hole 33.

[0040] The precise positioning of the positioning block 32 and the positioning hole 33 ensures that the bucket is accurately positioned during installation, preventing deviation or loosening, thereby improving the assembly accuracy and ensuring that the bucket always stays in the predetermined position, enhancing safety and stability.

[0041] The bottom surface of the rotating sleeve 21 is provided with an extrusion block 34, and the outer wall of the fixed sleeve 10 is fixed with a side plate 35. The side plate 35 is provided with multiple sets of return springs 36 respectively connected to the multiple sets of extrusion blocks 34.

[0042] The design of the compression block 34 and the return spring 36 ensures that the rotating sleeve 21 can effectively withstand external forces and return to its original position during operation. The return spring 36 provides the necessary reverse force to ensure the stable rotation of the rotating sleeve 21 and reduce vibration, thereby improving the service life and overall stability of the device.

[0043] In this embodiment, two sets of supports 1 are installed at the inlet and outlet respectively. The motor 4 is started to drive the drive wheel 2 to rotate, and the drive wheel 2 drives the transmission chain 5 and the transmission wheel 3 to rotate. The transmission chain 5 drives multiple sets of buckets 7 to scoop up and lift the bulk material. When the buckets 7 need to be replaced, the rotating sleeve 21 drives multiple sets of pressing blocks 34 to press multiple sets of return springs 36 respectively. At the same time, multiple sets of limiting blocks 20 slide along the limiting groove 22 into the unlocking hole 23, so that the multiple sets of limiting blocks 20 are released. The rotating sleeve 21 abuts against the sliding sleeve 18 and the sliding groove 15 by multiple sets of push springs 28, thereby releasing the pressure ring 17 from the abutment of multiple sets of locking blocks 13. Then, the locking blocks 13 are reset by multiple sets of compression springs 24, causing them to slide along the inclined groove 11 through the inclined block 12 and drive the locking blocks 13 to disengage from the locking groove 14, thereby releasing the fixing of the locking rod 9. Then, the fixing sleeve 10 is disconnected from the locking rod 9, and the bottom of the fixing sleeve 10 abuts against the inner wall of the bucket 7, and then the bucket 7 can be disassembled.

[0044] More specifically, when different models of buckets 7 need to be installed, the insertion rod 8 is inserted into the reserved hole on the bucket 7, and then the fixing sleeve 10 is inserted into the locking rod 9 and abuts against the inner wall of the bucket 7. The sliding sleeve 16 is pushed to drive the pressure ring 17 to push the multiple sets of locking blocks 13, so that the multiple sets of locking blocks 13 are engaged in the slot 14 and compress the compression spring 24. Then, multiple sets of limiting blocks 20 are inserted into the unlocking hole 23. The multiple sets of return springs 36 push the compression block 34 to drive the rotating sleeve 21 to rotate, so that the multiple sets of limiting blocks 20 slide in the limiting groove 22. The multiple sets of limiting blocks 20 abut against the rotating sleeve 21 and limit the sliding sleeve 16, thus completing the installation of the bucket 7.

[0045] In summary, during the use or operation of the overall equipment: the two sets of supports 1 are installed at the inlet and outlet respectively. The motor 4 is started, driving the drive wheel 2 to rotate. The drive wheel 2 drives the transmission chain 5 and transmission wheel 3 to rotate. The transmission chain 5 drives multiple sets of buckets 7 to scoop up and lift the bulk material. When it is necessary to replace the buckets 7, rotating the rotating sleeve 21 drives multiple sets of pressing blocks 34 to press multiple sets of return springs 36, simultaneously causing multiple sets of limiting blocks 20 to slide along the limiting groove 22 into the unlocking hole 23, thus allowing the multiple sets of limiting blocks... 20 Release the contact with the rotating sleeve 21, and push the connecting sleeve 18 and the sliding along the slide groove 15 through multiple sets of push springs 28, so that the pressure ring 17 releases the contact with multiple sets of locking blocks 13. Then, the locking blocks 13 are reset by multiple sets of compression springs 24, so that they slide along the inclined groove 11 through the inclined block 12 and drive the locking blocks 13 to disengage from the locking groove 14, thereby releasing the fixation of the locking rod 9. Then, the fixing sleeve 10 and the locking rod 9 are disconnected, and the contact between the bottom of the fixing sleeve 10 and the inner wall of the bucket 7 is released. Then the bucket 7 can be disassembled.

[0046] When different models of buckets 7 need to be installed, insert the rod 8 into the reserved hole on the bucket 7, then insert the fixing sleeve 10 into the locking rod 9 and abut against the inner wall of the bucket 7. Push the sliding sleeve 16 to drive the pressure ring 17 to push the multiple sets of locking blocks 13, so that the multiple sets of locking blocks 13 are engaged in the slot 14 and compress the compression spring 24. Then, the multiple sets of limiting blocks 20 are inserted into the unlocking hole 23. The multiple sets of return springs 36 push the compression block 34 to drive the rotating sleeve 21 to rotate, so that the multiple sets of limiting blocks 20 slide in the limiting groove 22. The multiple sets of limiting blocks 20 abut against the rotating sleeve 21 and limit the sliding sleeve 16, thus completing the installation of the bucket 7.

[0047] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
