Description

Technical Field

[0001] The utility model relates to the technical field of crusher equipment, in particular to a long drill rod structure for a crusher. Background Art

[0002] Anchor skids are devices used to crush rocks and ores. They play a vital role in industries such as building materials, ore crushing, rail transportation, energy, and mining. They are essential in construction, especially in crushing ore or rock in mine tunnels and mountain walls.

[0003] The operating principle of a bolt skidder involves applying pressure to the target rock or ore using a high-strength drill rod, thereby breaking it. The drill rod length, to a certain extent, determines the operating range and efficiency of the bolt skidder. Currently, the commonly used drill rod length for bolt skidders is 550mm, which meets most project requirements. However, in some special cases, such as when the ore blocks in the mine tunnel wall or the rocks in the mountain wall are large or the location is complex, a 550mm drill rod length may be insufficient.

[0004] When the drill rod is not long enough to reach the target, the operator needs to adjust the angle of the anchor skidder. This adjustment involves resetting the angle of the anchor skidder to ensure the drill rod effectively contacts the target rock or ore. This not only increases operational complexity but also significantly reduces work efficiency. This is because angle adjustment is often time-consuming and manual, and each adjustment may involve multiple steps and detailed processing.

[0005] Furthermore, frequent angle adjustments can lead to unstable operation of the anchor skimmer, increasing wear and tear on the equipment and maintenance costs. In some projects, particularly those involving complex terrain or uneven rock distribution, the frequency and difficulty of anchor skimming operations can increase significantly, further impacting work efficiency and project progress. Operators not only have to constantly adjust the equipment's angle but also need to constantly monitor its stability and operational safety, which undoubtedly adds to the challenges of the job.

[0006] In summary, when the anchor skimmer's drill rod is not long enough, the operator must frequently adjust the angle of the equipment, which reduces work efficiency, increases operational difficulty, and may result in additional equipment maintenance costs. In this case, the overall progress and efficiency of the project construction will be adversely affected. Based on this, the present application provides a long drill rod structure for a crusher.

[0037] See also Figure 1-8 , anchor prying machines are widely used in building materials, ore crushing, railway transportation, energy, mining and other industries. In engineering construction, it is usually necessary to crush ore blocks on the wall of the mine tunnel or stones on the wall of the mountain. At present, the common length of the drill rod 12 used in the anchor prying machine is 550mm. When performing anchor prying operations, the drill rod 12 is not long enough, and the operator needs to operate the anchor prying machine to adjust the angle so that the drill rod 12 contacts the work object. Therefore, the anchor prying operations often increase and the work efficiency is reduced. Based on this, the present application provides a long drill rod 12 structure for a crusher, including a connecting seat 1 connected to the crusher, a connecting member 2 arranged below the connecting seat 1, and an extension portion 3 combined with the connecting member 2 to form an extension structure;

[0038] The connecting seat 1 includes a seat body 11, and a drill rod 12 is provided below the seat body 11;

[0039] The outer side of the drill rod 12 is combined with the connector 2 to form a fastening area for the extension 3 to be connected;

[0040] The connector 2 includes a sleeve 21, a positioning ring 25 is provided on the inner side of the sleeve 21, one or more reinforcing rods 24 are inserted in the middle of the positioning ring 25, and reinforcement tubes 26 are provided at both ends of the reinforcing tube, one of which is combined with the end of the drill rod 12;

[0041] Positioning holes 23 are provided on the outside of the drill rod 12 and the sleeve 21 . A latch is inserted into the positioning hole 23 to maintain the stability of the connection between the sleeve 21 and the drill rod 12 .

[0042] The connecting base 1 is a basic component fixed to the crusher, providing a stable support for the entire drill rod 12. The structure of the connecting base 1 is usually strong and durable, and can withstand the high-intensity pressure generated by the crusher during operation.

[0043] The drill rod 12 is fixed below the connector 1. The outer side of the drill rod 12 is designed as a fastening area for the connector 2, allowing the drill rod 12 to be stably connected to other components. The length of the drill rod 12 determines the basic length in this structure, and can be further extended to meet specific operation requirements.

[0044] Connector 2 primarily comprises a sleeve 21, the interior of which is designed to fit tightly against the outside of drill rod 12. A retaining ring 25 is located inside sleeve 21, with one or more reinforcing rods 24 inserted into the center of retaining ring 25. These reinforcing rods 24 increase the stability of connector 2, preventing it from loosening during crushing operations.

[0045] Each reinforcing rod 24 is provided with a reinforcement tube 26 at both ends, which enhances the overall stability of the drill rod 12 and the connector 2 by combining with the end of the drill rod 12. The reinforcement tube 26 can effectively disperse the force applied to the drill rod 12 and prevent damage caused by local stress concentration.

[0046] Both the drill rod 12 and the sleeve 21 have positioning holes 23 on their exteriors. These holes serve to provide a mating point for the latch, ensuring a stable and reliable connection between the drill rod 12 and the sleeve 21. The design of these holes prevents the drill rod 12 and the sleeve 21 from accidentally becoming loose during operation.

[0047] The pin is inserted into the positioning hole 23 to fix the connection between the drill rod 12 and the sleeve 21. This fixing method can ensure that the extension part 3 will not move or dislocate during the crushing operation, thereby improving the stability of the overall structure.

[0048] The design of the sleeve 21, locating ring 25, and reinforcing rod 24 in the connector 2 significantly enhances the stability of the drill rod 12 connection. The use of the reinforcing tube 26 and the latch ensures a secure connection between the drill rod 12 and the sleeve 21, preventing loosening or falling off under high-intensity working conditions.

[0049] The introduction of the extension 3 can effectively increase the length of the drill rod 12, thereby expanding the operating range of the crusher. This can reduce the need to frequently adjust the angle of the equipment, improve overall operating efficiency, and reduce the time wasted due to angle adjustments.

[0050] The stable connection structure reduces the wear and tear of the equipment and the frequency of failure, thereby reducing maintenance and repair costs. The design of the reinforcement tube 26 and the reinforcement rod 24 increases the durability of the structure and extends the service life of the equipment.

[0051] This structure can effectively cope with environments with complex terrain or uneven rock distribution. By adjusting the length of the drill rod 12, it can adapt to different operating requirements, further improving the applicability and flexibility of the crusher.

[0052] Due to the stable connection between the drill rod 12 and the connecting piece 2, the operator can focus more on the crushing operation instead of frequently adjusting the equipment. This design simplifies the operation process and improves work efficiency.

[0053] The reinforcement tube 26 includes a tube body 261 , and the inner wall of the tube body 261 is provided with clamping grooves 262 , which are distributed in a ring array.

[0054] Threaded rings are provided on the outer bottom and the center of the bottom of the cylinder 261 , namely a No. 1 threaded ring 263 and a No. 2 threaded ring 264 .

[0055] The No. 1 threaded ring 263 is adapted to the reinforcing rod, and the No. 2 threaded ring 264 is adapted to one end of the extension portion 3 .

[0056] The main structure of the reinforcement cylinder 26 is a cylinder body 261 , the inner and outer walls of which are precisely designed to fit tightly with other components.

[0057] Slots 262: Slots 262 are arranged around the inner wall of the barrel 261 in a circular array. The arrangement of slots 262 allows the reinforcement barrel 26 to be securely fastened to the drill rod 12 or other accessories. The circular array of slots 262 ensures even distribution of force on the reinforcement barrel 26 during use, enhancing stability.

[0058] The outer bottom of the reinforcement tube 26 is provided with a No. 1 threaded ring 263, which is used to adapt to the reinforcement rod. The design of the No. 1 threaded ring 263 can make the connection between the reinforcement rod and the reinforcement tube 26 more secure, and prevent the reinforcement rod from loosening during operation.

[0059] A second threaded ring 264 is provided at the center of the outer bottom of the reinforcement tube 26, which is used to adapt to one end of the extension part 3. The design of the second threaded ring 264 enables the reinforcement tube 26 to be firmly connected to the extension part 3, thereby forming a solid integral structure.

[0060] The reinforcement tube 26 is connected to the reinforcement rod by a number one threaded ring 263, ensuring that the connection between the reinforcement tube 26 and the drill rod 12 will not loosen during the crushing operation. The slot 262 of the reinforcement tube 26 is designed to cooperate with the corresponding structure on the drill rod 12 to form a tight connection.

[0061] The second threaded ring 264 is connected to one end of the extension part 3. The threaded fit ensures the stability of the reinforcement tube 26 on the extension part 3, so that the extension part 3 will not have problems due to uneven force or looseness during use.

[0062] The slots 262 and threaded ring design on the inner wall of the reinforcement tube 26 significantly enhance the connection stability between the drill rod 12 and the connector 2. The annular array of slots 262 ensures uniform force distribution, and the threaded fit of the reinforcement tube 26, the reinforcement rod, and the extension 3 prevents loosening and improves overall stability.

[0063] The design of the reinforcement barrel 26 increases its durability through the precise fit of the threaded ring. The threaded connection effectively disperses the forces generated during the crushing process, reducing wear caused by concentrated force on the structure and extending the service life of the equipment.

[0064] The design of the threaded ring makes the connection of the reinforcement tube 26 to the reinforcement rod and the extension 3 easier, reducing the complexity in the installation and removal process. This design not only saves time, but also reduces the dependence on the operator's skills.

[0065] The stable connection reduces the need for frequent adjustments due to loose connections, thereby improving the efficiency of the crushing operation. During operation, the stability of the structure allows the equipment to operate more reliably and avoids work interruptions caused by equipment instability.

[0066] The design of the reinforcement tube 26 enables it to remain stable under various complex operating conditions. Regardless of the hardness of the rock or the complexity of the operating environment, the structure of the reinforcement tube 26 can adapt and maintain stability, ensuring the effective operation of the equipment under harsh conditions.

[0067] A jacket 22 is provided on the outer side of the sleeve 21 , and the jacket 22 is tightly fitted to the outer side of the extension portion 3 .

[0068] The jacket 22 includes two semicircular outer shells, which are locked together by fasteners.

[0069] The front end of the extension portion 3 is configured in a conical shape, and is used to cooperate with the crusher to crush the target area.

[0070] The jacket 22 is an auxiliary structure installed on the outside of the sleeve 21 , and its design purpose is to further enhance the connection stability between the sleeve 21 and the extension portion 3 .

[0071] The jacket 22 is composed of two semicircular shells. These two shells fit tightly together and are locked by fasteners to form a stable overall structure. The semicircular shell design ensures that the jacket 22 evenly wraps around the sleeve 21 and fits tightly with the extension 3.

[0072] The fasteners for fixing the two semicircular shells together can be screws, bolts or other suitable fixing devices. The design of the fasteners ensures that the jacket 22 will not become loose during operation, thereby maintaining the stability and reliability of the jacket 22.

[0073] The outer side of the extension 3 is designed to fit tightly against the inner side of the jacket 22. This tight fit keeps the position of the extension 3 in the sleeve 21 stable, preventing any movement or displacement during the crushing operation.

[0074] The front end of the extension 3 is conical in shape. This design is intended to optimize the crushing effect of the crusher in the target area. The conical front end can better penetrate the rock or ore, thereby improving the efficiency and effect of crushing.

[0075] The semicircular shell design of the jacket 22 and the use of fasteners provide strong structural stability. The jacket 22 tightly wraps the sleeve 21 and fits the outer side of the extension 3, effectively preventing the loosening or displacement of the connection part, thereby ensuring the stability of the entire structure.

[0076] The conical design of the front end of the extension 3 enables the drill rod 12 to enter the target area more effectively. This design not only improves the penetration of rocks or ores, but also optimizes the crushing process, thereby improving crushing efficiency.

[0077] The design of the jacket 22 simplifies the connection between the extension 3 and the sleeve 21. Since the jacket 22 can be firmly fixed to the sleeve 21, the installation and removal process is more efficient and the need for complex maintenance operations is reduced.

[0078] The stable connection structure and optimized design improve the safety of the equipment. The combination of the jacket 22 and the conical extension 3 ensures that the equipment will not cause accidents due to unstable connection during high-intensity operations, thereby improving the safety of operators.

[0079] The tight fit of the jacket 22 and the conical front end design allow the equipment to adapt to a variety of complex operating environments. Whether it is rock with different hardness or ore shapes, this design can effectively cope with it, ensuring the wide applicability of the equipment.

[0080] A base 13 is provided at one end of the drill rod 12 close to the reinforcement tube 26 , a combination hole 14 is provided in the middle of the base 13 , auxiliary holes 15 are provided on both sides of the combination hole 14 , and the combination hole 14 and the auxiliary holes 15 are adapted to the reinforcement tube 26 .

[0081] One end of the drill rod 12 near the reinforcement tube 26 is provided with a base 13. The design position of the base 13 is very critical, and it provides a stable connection support between the drill rod 12 and the reinforcement tube 26.

[0082] The main function of the base 13 is to provide a solid fixed foundation for the reinforcement tube 26 so that it can withstand crushing forces and external stresses during operation. The structure of the base 13 must be strong enough to ensure that it will not deform or break under high-intensity operations.

[0083] A combination hole 14 is provided in the middle of the base 13. This hole 14 is designed to mate with the internal structure of the reinforcement tube 26, ensuring a more secure connection between the drill rod 12 and the reinforcement tube 26. The size and shape of the combination hole 14 precisely match the corresponding structure within the reinforcement tube 26, ensuring a tight and stable connection.

[0084] Auxiliary holes 15 are provided on both sides of the combination hole 14. Auxiliary holes 15 are designed to further strengthen the fit between the drill rod 12 and the reinforcement tube 26. The auxiliary holes 15 match the structure of the reinforcement tube 26, providing additional support and ensuring that the drill rod 12 does not shift or loosen due to uneven force during operation.

[0085] The design of the combination hole 14 and the auxiliary hole 15 ensures the stability of the connection between the drill rod 12 and the reinforcement tube 26. The main function of the combination hole 14 is to provide a fixing point for the core, while the auxiliary hole 15 serves as an additional support point to ensure the stability of the entire structure during high-intensity crushing operations.

[0086] The design of the combination hole 14 and the auxiliary hole 15 must precisely match the internal structure of the reinforcement tube 26. Typically, the reinforcement tube 26 has corresponding matching structures (such as the slot 262 and the positioning ring 25). These designs ensure a tight fit between the base 13 and the reinforcement tube 26, reducing the risk of loosening of the connection.

[0087] The arrangement of base 13 and the design of combination hole 14 and auxiliary hole 15 provide a more stable connection between drill rod 12 and reinforcement tube 26. Combination hole 14 provides the primary fixing point, while auxiliary hole 15 further enhances the stability of the connection. This design effectively prevents loosening of the connection due to uneven force or vibration, thereby improving the stability of the entire structure.

[0088] The design of the base 13 enables the drill rod 12 to better withstand the pressure and external load from the reinforcement tube 26. The strong base 13 provides the necessary support for the reinforcement tube 26, preventing structural deformation or damage that may occur during high-intensity operations.

[0089] The precise design of the combination hole 14 and the auxiliary hole 15 ensures a good fit between the drill rod 12 and the reinforcement tube 26. This design can ensure the fastening of the connection part and reduce the risk of reduced work efficiency or equipment failure caused by poor connection.

[0090] The optimized connection design, the arrangement of the base 13, the combination hole 14, and the auxiliary hole 15, simplifies the maintenance process of the device. Due to the improved stability of the connection structure, the number of steps required for maintenance and adjustment of the device is reduced, thereby improving work efficiency.

[0091] This design maintains structural stability during high-intensity crushing operations and adapts to a variety of complex operating environments. Whether facing hard rock or irregular ore, this design can effectively withstand the high loads during operation and ensure long-term stable operation of the equipment.
