Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, specifically to an adjusting nut for the release cylinder of a multi-cylinder cone crusher. Background Technology

[0002] Currently, multi-cylinder cone crushers are widely used in mining, metallurgy, construction, chemical and other fields, especially in construction engineering, highway construction, water conservancy projects and other projects, where they play an important role. They are characterized by high crushing ratio, large processing capacity and low operating cost.

[0003] The multi-cylinder cone crusher includes a frame, a fixed cone assembly, a moving cone assembly, an eccentric assembly, a main shaft, and a main drive hydraulic motor. The moving cone assembly and the eccentric assembly are assembled on the main shaft. The main drive hydraulic motor is mounted on the frame. The main drive hydraulic motor is connected to the eccentric assembly through gears. The eccentric assembly is connected to the moving cone assembly. The fixed cone assembly is connected to the frame through a release cylinder.

[0004] The working parts of a multi-cylinder hydraulic cone crusher consist of a moving cone and a fixed cone. During operation, the motor drives the moving cone to oscillate along the inner surface via a pulley, drive shaft, pinion, and gear. Near the fixed cone, the material is crushed by the compression and bending of the moving cone. Further away from the moving cone, the crushed material falls from the bottom of the cone due to gravity. The entire crushing and unloading process proceeds continuously along the inner surface. The release cylinder section consists of a release cylinder, accumulator, and connecting pipelines. The release cylinder primarily serves as an overload protection mechanism and a clearing chamber. During normal crushing, it absorbs and buffers the impact of the adjusting ring jumping caused by a few hard materials.

[0005] In traditional techniques, due to the frequent operation of the release cylinder, the nut on top of the cylinder needs to be coated with thread-locking compound to prevent it from loosening and to avoid damage to crusher components caused by misalignment of the fixed cone assembly. However, during maintenance, the application of thread-locking compound makes nut removal extremely difficult, causing significant challenges at the maintenance site and impacting the maintenance progress.

[0013] The following describes specific embodiments, such as Figures 1 to 5 The present invention is further illustrated as shown, and is intended only to provide a better understanding of its contents. Therefore, the examples given do not limit the scope of protection of the present invention.

[0014] An adjusting nut for a release cylinder of a multi-cylinder cone crusher includes a nut body, which is formed by a first half nut 1 and a second half nut 2 being snapped together. The inner walls of the first half nut 1 and the second half nut 2 are respectively provided with threaded structures. After they are snapped together, they form a nut that is compatible with the screw 13 at the top of the release cylinder.

[0015] The two ends of the first half nut 1 extend outward to form connecting plate 3, and the two ends of the second half nut extend outward to form connecting plate 4. The two are fastened together and connected into a whole by fasteners. When the first half nut 1 and the second half nut 2 are fastened together, the connecting plate 3 and the connecting plate 4 abut against each other.

[0016] The fastener consists of a fastening plate 5 and screws 6. Fixing holes 7 are provided on the two connecting plates 3 and 4 respectively. Each connecting plate (connecting plate 3 and connecting plate 4) has two fixing holes 7, and the fixing holes 7 on the connecting plate 3 and connecting plate 4 on the same side are set one-to-one. There are two fastening plates 5. Each fastening plate 5 has a threaded hole 8 corresponding to the fixing hole 7 on its side. The threaded hole 8 also corresponds one-to-one with the fixing hole 7. Each screw 6 passes through the connecting plate 3 and connecting plate 4 and is inserted into the threaded hole 8 on its fastening plate 5 and is threadedly connected to the threaded hole 8.

[0017] A positioning pin 9 is fixedly connected to the surface of each connecting plate 3 on the opposite side of the connecting plate 4. A positioning groove 10 adapted to the positioning pin 9 is opened on the surface of each connecting plate 4 on the opposite side of the connecting plate 3. When the first half nut 1 and the second half nut 2 are engaged, the positioning pin 9 is inserted into the positioning groove 10.

[0018] In this embodiment, the outer ends of the two connecting plates 3 of the first half nut 1 are respectively provided with notches 1; 11, and the outer ends of the two connecting plates 4 of the second half nut 2 are respectively provided with notches 2; 12. After the first half nut 1 and the second half nut 2 are fastened together, each notch 1; 11 and its corresponding notch 2; 12 form a gap.

[0019] In this embodiment, the assembly is performed first. The first half nut 1 and the second half nut 2 are fastened together, ensuring that the positioning pin 9 is inserted into the positioning groove 10. Then, screws are used to thread the nuts through the connecting plate 3 and the fixing hole 7 on the connecting plate on both sides of the nut body and then threadedly connected to the fastening plate 5 on the corresponding side. Then, thread fastener is applied to the threads on the inner wall of the assembled nut body. Finally, the assembled structure is screwed into the designed position of the screw 13 at the top of the release cylinder.

[0020] When it is necessary to remove the adjusting nut on the release cylinder, unscrew screw 6, insert a flat spatula into the notches on both sides of the nut body, and separate connecting block one and connecting block two on both sides of the nut body to complete the disassembly. It is simple and efficient.

[0021] This invention sets the adjusting nut into a modular structure. When disassembling, simply unscrew the screws on the connecting plate and use a flat chisel to insert into the notch to separate connecting plate one and connecting plate two. This allows the first half nut and the second half nut to be separated, reducing the difficulty of disassembling the nut on the release cylinder and improving disassembly efficiency.

[0022] The above description is merely a preferred embodiment of the present utility model and does not limit the scope of the present utility model.
