A large scale crusher

Abstract

This utility model provides a large crusher, relating to the field of crusher technology, including a shell. Side plates are provided on both sides of the shell. A sliding groove is formed on one side of each side plate, and a sliding plate is slidably connected to the inner wall of the sliding groove. A crushing blade assembly is rotatably connected between one side of each of the two sliding plates. Two first hydraulic rods are fixedly connected to one side of each side plate, and a support plate is fixedly connected between one end of each of the two first hydraulic rods. In this utility model, the first hydraulic rods drive the support plate to move, which in turn drives the sliding rod to move via a ring plate. This causes the locking rod to separate from the locking groove via the sliding rod, thus eliminating the limiting effect on the left side of the crushing blade assembly. Then, the second hydraulic rod drives the fixing plate to move, causing the fixing rod to separate from the fixing groove, thus eliminating the limiting effect on the right side of the crushing blade assembly. At this point, the crushing blade assembly and the sliding plate can be removed and replaced together.

Description

Technical Field

[0001] This utility model relates to the field of crusher technology, and in particular to a large crusher. Background Technology

[0002] While existing crushers are equipped with robust and durable crushing blades, these blades inevitably wear down over time, requiring regular cleaning. In the use of large crushers, the large volume of materials processed, and the fact that the crusher itself is designed to handle waste materials or ores, generates significant amounts of dust and impurities during the crushing process. The vibrations caused by the crusher's operation scatter these dust and impurities, which easily adhere to bolts and the surrounding area. Over time, this dust and impurities accumulate on the bolts and threaded grooves, forming oxides or deposits that further tighten the connection between the bolts and threaded grooves, increasing the difficulty of disassembly. Due to the accumulation of impurities around the bolts, conventional disassembly methods may become inconvenient, making maintenance more complex and time-consuming. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies. While existing crushers are equipped with robust and durable crushing blades, these blades inevitably wear down over time, requiring regular cleaning. In the use of large crushers, the large volume of materials processed, and the fact that the crusher itself is used to process waste materials or ores, generates a large amount of dust and impurities during the crushing process. The vibration of the material during operation causes dust and impurities to scatter, easily adhering to bolts and their surrounding areas. Over time, this dust and impurities accumulate at the bolt and thread groove, forming oxides or impurity deposits, further tightening the connection between the bolt and thread groove, thus increasing the difficulty of disassembly. Due to the accumulation of impurities around the bolts, conventional disassembly methods may become inconvenient, making maintenance more complex and time-consuming. Therefore, this invention provides a large crusher.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a large crusher, comprising a shell, side plates on both sides of the shell, a groove on one side of the side plate, a sliding plate slidably connected to the inner wall of the groove, a crushing blade assembly rotatably connected between one side of the two sliding plates, two first hydraulic rods fixedly connected to one side of the side plate, a support plate fixedly connected between one end of the two first hydraulic rods, two rotating holes on one side of the support plate, an annular plate rotatably connected to the inner wall of the rotating holes, a sliding rod fixedly connected to the inner wall of the annular plate, a locking rod fixedly connected to one end of the sliding rod, the shaft of the crushing blade assembly rotatably extending through to the outside of the sliding plate, a locking groove on the shaft of the crushing blade assembly, multiple fixing grooves on one side of the sliding plate, a locking hole on one side of the side plate, a sliding fixing rod slidably fixed to the inner wall of the locking hole, and the outer surface of the fixing rod slidably connected to the inner wall of the fixing groove.

[0005] In a preferred embodiment, a second hydraulic rod is fixedly connected to one side of the side plate, and a fixing plate is fixedly connected to one end of the second hydraulic rod. One side of the fixing plate is fixedly connected to one end of the fixing rod.

[0006] In a preferred embodiment, a gear is fixedly sleeved on the outer surface of the slide rod, and two gears are meshed together. One end of one of the slide rods is provided with a motor assembly.

[0007] In a preferred embodiment, a branch pipe is fixedly connected to one side of the side plate, and the inner wall of the branch pipe is slidably connected to the outer surface of the slide rod.

[0008] In a preferred embodiment, a rotating groove is provided at one end of the branch pipe, a rotating plate is rotatably connected to the inner wall of the rotating groove, a support hole is provided on one side of the rotating plate, and a positioning block is fixedly connected to the inner wall of the support hole.

[0009] In a preferred embodiment, the outer surface of the slide bar is provided with a plurality of positioning grooves, and the inner wall of the positioning groove is slidably connected to the outer surface of the positioning block.

[0010] In a preferred embodiment, a plurality of support rods are fixedly connected to one side of the ring plate, and a plurality of support grooves are provided on one side of the rotating plate. The outer surface of the support rods is slidably connected to the inner wall of the support groove.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This invention uses a first hydraulic rod to move a support plate, which in turn moves a sliding rod via a ring plate. This sliding rod then separates the locking rod from the locking groove, eliminating the limiting effect on the left side of the crusher assembly. Next, a second hydraulic rod moves a fixing plate, which in turn separates the fixing rod from the fixing groove, eliminating the limiting effect on the right side of the crusher assembly. At this point, the crusher assembly and the sliding plate can be removed and replaced together. When the support rod is inside the support groove, the structural stability of the support plate is increased through the cooperation of the support rod and the rotating plate. The positioning block and positioning groove allow the positioning block to slide, enabling the sliding rod to move along the inner wall of the rotating plate. The positioning block and the inner wall of the rotating plate fix the support rod and support groove, ensuring they are separated. The ring plate and positioning block then synchronize the support rod and support groove, preventing misalignment and facilitating the assembly of the support rod and support groove.

A gear 14 is fixedly sleeved on the outer surface of the slide rod 13, and two gears 14 are meshed together. A motor assembly is provided at one end of one of the slide rods 13. Through the above embodiments, the first hydraulic rod 10 drives the support plate 12 to move, and the support plate 12 can drive the slide rod 13 to move through the ring plate 22. At this time, the slide rod 13 can drive the locking rod 15 to separate from the locking groove 16, and the limiting effect on the left side of the crusher assembly 6 disappears. Then, the second hydraulic rod 11 drives the fixing plate 9 to move, and the fixing plate 9 drives the fixing rod 8 to separate from the fixing groove 7, and the limiting effect on the right side of the crusher assembly 6 disappears. At this time, the crusher assembly 6 and the slide plate 5 can be taken out together for replacement. A branch pipe 17 is fixedly connected to one side of the side plate 2, and the inner wall of the branch pipe 17 is slidably connected to the outer surface of the slide rod 13. Through the above embodiments, the support effect of the side plate 2 on the slide rod 13 can be extended by the branch pipe 17, thereby making the structure of the slide rod 13 more stable.
