Description

Technical Field

[0001] This utility model relates to the field of transportation or storage device technology, and in particular to an adjustable buffer mechanism for a mining feeder. Background Technology

[0002] In the mining and mineral processing process, the mining feeder is a key piece of equipment connecting ore storage with subsequent crushing and conveying processes. Its stable operation directly affects the efficiency and safety of the entire production line. When the feeder receives ore pouring down from the hopper, it must withstand huge instantaneous impact forces, which can easily lead to equipment structural fatigue, parts damage, and even shutdown failures. Therefore, the buffer mechanism, as the "protective barrier" of the feeder, plays an indispensable role in extending the service life of the feeder and reducing maintenance costs by absorbing impact energy and reducing vibration.

[0003] Traditional mining feeders often use bolted installation for their buffer mechanisms. In practice, this method requires the use of wrenches, sockets, and other tools for bolt connection, making installation and disassembly cumbersome and time-consuming. For example, during routine maintenance to replace worn buffer springs or rubber buffer blocks, operators need to spend a lot of time tightening multiple bolts one by one. The entire process often takes several hours or even longer, greatly affecting the equipment maintenance efficiency. At the same time, frequent bolt disassembly can easily lead to thread wear and stripping, which reduces the reliability of the connection between the buffer mechanism and the feeder support legs. It may even lead to serious safety hazards such as the buffer mechanism loosening or falling off during equipment operation. Utility Model Content

This mechanism can solve the problem that in practical applications, bolt connections require the use of multiple tools such as wrenches and sockets, and the installation and disassembly process is cumbersome and time-consuming. Taking the routine maintenance and replacement of worn buffer springs or rubber buffer blocks as an example, operators need to spend a lot of time tightening multiple bolts one by one. The entire process often takes several hours or even longer, which greatly affects the maintenance efficiency of the equipment.

[0008] Preferably, the ends of the two limiting members near the second limiting slider grooves both slide into the interior of the connecting seat groove and are respectively slidably connected to the interior of the corresponding second limiting slider grooves.

[0009] Preferably, the arc-shaped outer walls of the four elastic cards respectively cooperate with the arc-shaped inner walls of the upper and lower inner walls of the corresponding elastic card limiting grooves so that the limiting card post is engaged inside the elastic card limiting groove.

[0010] Preferably, the ends of the two limiting pins near the limiting member both slide into the interior of the first limiting slider groove and respectively contact the outer wall of the corresponding limiting member.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0021] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0022] Example 1: Reference Figure 1-4 Example of quick disassembly under normal working conditions (limiting slider + elastic card) Suitable for conventional working conditions such as coal mines and small metal mines, this device achieves quick disassembly through a basic limit slider and elastic card structure. The limit component uses ordinary engineering plastic limit sliders, which slide in conjunction with the first and second limit slider slots. The elastic card is made of arc-shaped spring steel, providing stable clamping force. When the limit card is pulled, the elastic card is compressed and deformed, causing the limit card to disengage from the limit slot. Pulling the pull rod then allows the limit slider to easily disengage, achieving quick disassembly of the connecting seat. This structure is low-cost, simple to operate, and suitable for daily inspection and maintenance.

[0023] Example 2: Reference Figure 5 Example of preventing loosening under high impact conditions (serrated limit block + reinforced elastic card) For mines handling high-hardness ores and large materials, such as iron ore and granite, a serrated limit block and a reinforced elastic card are used to enhance the anti-loosening performance. The limit component is replaced with a serrated limit block, and the serrated surface tightly engages with the serrated limit block groove of the mounting block. The elastic card is thickened and made of high-strength spring steel to increase the clamping force. Under high-impact conditions, the engagement structure of the serrated limit block effectively prevents the limit component from loosening, and the reinforced elastic card ensures that the limit pin is firmly locked. Even under strong vibration, the connecting seat will not fall off unexpectedly, ensuring the safe operation of the equipment.

[0024] Furthermore, when using this device, if a buffer mechanism needs to be installed, first align the mounting block 16 on the connecting seat 6 with the connecting seat groove 11 inside the fixed mounting seat 19 on the lower surface of the support seat 1. This allows the four T-shaped blocks on the outer wall of the mounting block 16 to slide into the corresponding grooves of the four T-shaped blocks on the inner wall of the connecting seat groove 11. During insertion, pull the lever 4 on the left and right outer walls of the fixed mounting seat 19, causing the limiting member 9 to slide within the first limiting slider groove 10, moving the limiting member 9 away from the mounting block 16 and providing space for the insertion of the mounting block 16. Then, after the mounting block 16 is fully inserted into the connecting seat groove 11, release the lever 4. Under the action of the return spring 12, the limiting member 9 will automatically... The device is reset, with one end sliding into the second limiting slider groove 15 on the left and right outer walls of the mounting block 16, achieving initial limiting of the mounting block 16. At this time, the mounting block 16 cannot move laterally within the connecting seat groove 11. Then, the limiting pin 5 is pushed, causing the elastic card 14 installed on the limiting pin 5 to engage with the arc-shaped grooves on the upper and lower inner walls of the elastic card limiting groove 13, thus locking the limiting pin 5 into the elastic card limiting groove 13. The elastic deformation of the elastic card 14 allows it to smoothly enter the groove and provides a certain fastening force, further fixing the position of the limiting pin 5, enhancing the stability of the connection, and completing the quick installation process. When disassembling, first pull the limiting pin 5 to make the elastic card 14 engage with the elastic card limiting groove 13. Card 14 disengages from the arc-shaped grooves on the upper and lower inner walls of the elastic card limiting groove 13, releasing the locking state of the limiting pin 5. The limiting pin 5 is then pulled out of the elastic card limiting groove 13. Then, the pull rod 4 is pulled again, causing the limiting member 9 to slide in the first limiting slider groove 10, so that the limiting member 9 exits from the second limiting slider groove 15 of the mounting block 16, releasing the limiting of the mounting block 16. At this time, the mounting block 16 on the connecting seat 6 can be pulled out from the connecting seat slide groove 11, realizing the quick disassembly of the buffer mechanism, which facilitates the inspection and replacement of the buffer components. In this way, during the operation of the feeder, the ore is conveyed through the transport mechanism 18. When the ore falls and impacts the feeder, the impact force... The impact force is first transmitted to the support base 1, which then transmits it to the buffer structure below via the fixed mounting base 19 and the connecting base 6. The rubber buffer column 8 then deforms due to its elasticity, absorbing part of the impact force and providing initial buffering. At the same time, the buffer spring in the elastic bolt 3 is compressed under the impact force, further buffering the impact force between the base 2 and the connecting base 6. In addition, the buffer mechanism 7 installed on the left and right outer walls of the base 2 and the connecting base 6 absorbs and dissipates vibration energy through its internal dampers, providing more precise buffering adjustment of the impact force and gradually reducing it. This protects the main structure of the feeder from damage and ensures the stable and safe operation of the feeder.

[0025] The quick-release limiting component 9, including the serrated limiting block 17 and the mounting block 16, the limiting pin 5 and the elastic card limiting groove 13, etc., form a multi-limiting and fixing mechanism, realizing the quick assembly and disassembly of the buffer mechanism. Compared with the traditional bolt fixing method, the operator does not need to use tools such as wrenches and sockets. He only needs to pull the lever 4 to control the sliding of the limiting component 9. With the locking and unlocking of the elastic card 14, the installation and disassembly of the buffer mechanism can be completed quickly. Taking the replacement of worn buffer parts as an example, the traditional method may take several hours. This greatly reduces the equipment downtime for maintenance and significantly improves the overall operating efficiency of the mining production line.

[0026] Structural Description: Support Base 1: As the top foundation bearing component of the entire feeder buffer mechanism, it provides installation space for the transport mechanism 18. The transport mechanism 18 is installed inside the upper end of the support base 1 and is the starting platform for conveying mineral materials. At the same time, it is connected to the quick-release limiting components and buffer structure below through four fixed mounting bases 19. Base 2: Located at the bottom of the entire buffer mechanism, it plays a role in providing stable support. The four bases 2 are connected to the connecting seat 6 through rubber buffer columns 8 and elastic bolts 3. After being connected to the connecting seat 6, the buffer mechanism 7 is installed on the left and right outer walls through bolts to further enhance the buffering effect. Fixed mounting base 19: There are four in total, which are fixedly installed on the lower surface of the support base 1. They are important connecting carriers for quick release limit components and are used to realize quick assembly and disassembly with the connecting base 6. The left and right outer walls are provided with quick release related structures such as pull rod 4, return spring 12, and elastic card limit groove 13.

[0027] Connecting seat 6: Located between the fixed mounting seat 19 and the base 2, the upper surface is fixedly mounted with the mounting block 16, and the lower surface is fixedly connected with three rubber buffer columns 8. The four corner outer walls of the connecting seat 6 are fitted with elastic bolts 3, which are connected to the base 2 through the elastic bolts 3. The outer wall of the connecting seat has a connecting seat groove 11, a first limit slider groove 10 and other structures, which are used to cooperate with other components to achieve quick release and limit functions. Mounting block 16: It is fixedly installed on the upper surface of the connecting seat 6. Four T-shaped blocks are set on the outer wall, which are slidably connected to the inner wall of the connecting seat slide groove 11. This enables the mounting block 16 to slide stably in the connecting seat slide groove 11. At the same time, second limiting slider grooves 15 are opened on its left and right outer walls for cooperation with limiting member 9.

[0028] Limiting components 9: There are eight limiting components 9 in total, usually limiting sliders, and in some cases, serrated limiting blocks 17. Two limiting components 9 are slidably connected in the first limiting slider groove 10 and are slidably controlled by the pull rod 4. One end is fixedly connected to the pull rod 4, and the other end can slide to the second limiting slider groove 15 to limit the mounting block 16. When it is a serrated limiting block 17, its serrated surface cooperates with the inside of the serrated limiting block groove opened on the left and right outer walls of the mounting block 16 to provide a stronger limiting effect. Pull rod 4: Pull rod 4 is slidably connected to the left and right outer walls of the fixed mounting base 19. One end extends slidably into the first limiting slider groove 10 and is fixedly connected to the limiting member 9. The operator can pull the pull rod 4 to drive the limiting member 9 to slide in the first limiting slider groove 10, thereby adjusting the position of the limiting member 9. Return spring 12: It is sleeved on the outer wall of the pull rod 4, and its two ends are fixedly connected to the outer wall of the limiting member 9 and the inner wall of the first limiting slider groove 10, respectively. When the pull rod 4 pulls the limiting member 9 to move, the pull rod 4 is released, and the return spring 12 can make the limiting member 9 automatically return to its original position. Elastic Card 14: There are four elastic cards 14. They are installed on the limit pin 5 by cooperating with the fixing rods in the upper and lower slots of the corresponding limit pin 5 through the four sliding grooves on the outer wall. The arc-shaped outer wall of the card cooperates with the inner wall of the arc-shaped groove in the upper and lower inner wall of the corresponding elastic card limit groove 13, so as to realize the locking and unlocking of the limit pin 5 in the elastic card limit groove 13, which plays a role in assisting fixation and quick assembly and disassembly. Limiting pin 5: It is slidably connected in the elastic card limiting groove 13. One end cooperates with the elastic card 14, and the other end can slide to the first limiting slider groove 10 and contact the outer wall of the limiting member 9 to enhance the stability of the connection and the limiting effect. Rubber buffer column 8: Three rubber buffer columns 8 are fixedly connected to the lower surface of each connecting seat 6. The twelve rubber buffer columns 8 are in groups of three, for a total of four groups. The end away from the connecting seat 6 is fixedly installed on the base 2. The elasticity of the rubber is used to initially buffer the impact force received by the feeder during operation and absorb some of the energy. Elastic bolts 3: Each of the twelve elastic bolts 3 consists of a bolt and a buffer spring. They are installed on the outer wall of the four corners of the connecting seat 6. The four corners of the four bases 2 have slots that cooperate with the corresponding elastic bolts 3 to connect with the connecting seat 6. While achieving the connection, the buffer springs can further buffer the impact force between the base 2 and the connecting seat 6.

[0029] Buffer mechanism 7: There are four buffer mechanisms 7, which are installed on the left and right outer walls after the base 2 and the connecting seat 6 are connected. Each one consists of a fixed plate and a damper. The damper can absorb and dissipate vibration energy, and make more precise buffering adjustments to the feeder to ensure the stability of the feeder operation. Transport mechanism 18: The transport mechanism 18 consists of a drive mechanism and a conveyor belt. It is installed inside the upper end of the support base 1 and is responsible for transporting the ore from the feeder inlet to the subsequent processing equipment. It is the core component of the feeder to realize the material transfer function.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
