[0002] Crushing equipment is a series of mechanical devices used to reduce large materials to smaller sizes. They crush solid materials such as stone, ore, metal, plastic, and wood into the required particle size through physical actions such as extrusion, shearing, impact, and grinding. They are widely used in many industries such as mining, construction, chemical, metallurgy, and environmental protection to meet the particle size requirements of different processes.

[0003] Quick-change blade crushing equipment refers to crushers designed with mechanisms for easy and quick disassembly and installation of blades. Such a design can significantly improve the maintenance efficiency of the equipment and reduce operating costs.

[0004] In traditional crushing equipment, the cutters are usually connected to the drive unit via a coupling. This connection method requires bolts to fix the coupling. When the cutter needs to be replaced, the operator must first remove the bolts at both ends of the coupling before the cutter can be replaced. This process is not only labor-intensive but also time-consuming, thus reducing the maintenance efficiency and production efficiency of the equipment. In addition, frequent removal and installation of bolts may damage the coupling and bolts, increasing maintenance costs and posing a potential safety risk to the operator. Therefore, a crushing equipment with a quick cutter replacement capability is proposed to address the above problems. Utility Model Content

As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0027] Please see Figure 1-6 This utility model provides a technical solution:

[0028] A crushing device with quick-change blades includes a support plate 1 and a crusher housing assembly 2. The crusher housing assembly 2 is fixedly connected to the top of the support plate 1. A blade drive assembly 3 is installed inside the crusher housing assembly 2. The crusher housing assembly 2 includes a frame shell 21. A hydraulic rod 22 is fixedly connected to the inside of the frame shell 21. A limit telescopic rod 23 is fixedly connected to the inside of the frame shell 21. An arc-shaped groove 24 is formed on the inner side of the upper end of the frame shell 21. A rail groove 25 is formed on the inner side of the frame shell 21 near the arc-shaped groove 24. The inner side of the rail groove 25 of the frame shell 21 slides... The upper baffle 27 is dynamically connected, and a fixed plate 26 is fixedly connected to one side of the upper baffle 27. The tool drive assembly 3 includes a tool body 31. A shaft roller 32 is fixedly connected to the inner side of the tool body 31, and a magnetic retaining ring 33 is fixedly connected to the outer side of the shaft roller 32. An insertion hole 34 is opened on the inner side of the tool body 31. The outer side of the shaft roller 32 is in contact with the inner side of the bearing 35. An insertion rod 36 is installed on the inner side of the insertion hole 34 opened in the tool body 31. A flange plate 37 is welded and fixedly connected to one side of the insertion rod 36. A drive device 38 is fixedly connected to the flange plate 37 by bolts.

[0029] As a further implementation of this solution, the top of the support plate 1 is fixedly connected to the bottom of the frame shell 21. The inner side of the frame shell 21 is hollow. The tool drive assembly 3 is installed inside the frame shell 21. There are two tool drive assemblies 3. The inner side of the frame shell 21 near the hydraulic rod 22 and the limiting telescopic rod 23 are provided with mounting holes. There are two hydraulic rods 22. The hydraulic rods 22 are fixed inside the left end and the right end of the frame shell 21. One side of the hydraulic rod 22 is fixedly connected to one side of the fixed plate 26. One side of the limiting telescopic rod 23 is fixedly connected to one side of the fixed plate 26. There are two limiting telescopic rods 23. There are two limiting telescopic rods 23 in each group. By controlling the hydraulic rods 22, the fixed plate 26 and the connected drive device 38, flange plate 37 and plug rod 36 can be moved. When the fixed plate 26 moves, the stability of the movement of the fixed plate 26 can be improved by the guidance and support of the limiting telescopic rod 23.

[0030] As a further implementation of this solution, the upper baffle 27 is a three-section rectangular body. The top of the upper baffle 27 is flush with the top of the frame shell 21. The number of upper baffles 27 is the same as the number of arc-shaped grooves 24. The arc-shaped grooves 24 are connected to the rail grooves 25. The bottom of the upper baffle 27 is an arc-shaped structure. The bottom of the upper baffle 27 is in contact with the top of the bearing 35. Under the action of the upper baffle 27 sliding inside the rail grooves 25, the stability of the fixed plate 26 when moving is further improved. At the same time, the sealing of the upper baffle 27 can prevent external debris from entering the arc-shaped grooves 24 from the top, and at the same time improve the stability of the bearing 35 rotation.

[0031] As a further implementation of this solution, bearings 35 and magnetic retaining rings 33 are embedded inside the arc-shaped grooves 24. The number of bearings 35 is the same as the number of arc-shaped grooves 24. A shaft roller 32 is installed inside the frame housing 21. The arc-shaped grooves 24 penetrate the upper end of the frame housing 21. The shaft roller 32 is a slotted cylinder. The right side of the insertion hole 34 has the same shape as the right side of the insertion rod 36. The insertion rod 36 slides inside the insertion hole 34. The number of insertion rods 36 is the same as the number of insertion holes 34. Bearings 35 are sleeved on the outside of the shaft roller 32. The outer part of the hole 34 near the shaft roller 32 has an arc-shaped chamfer structure, and one end of the insertion rod 36 has an arc-shaped chamfer structure. The insertion rod 36 is moved by the fixing plate 26, so that the insertion rod 36 is inserted into the interior of the insertion hole 34, which improves the connection efficiency between the insertion rod 36 and the insertion hole 34. When the drive device 38 is started, the flange plate 37, the insertion rod 36, the shaft roller 32 and the cutter body 31 can rotate simultaneously, which reduces the dependence on bolts and also reduces the risk of equipment failure caused by loose or damaged bolts, thus enhancing the stability and reliability of the equipment.

[0032] Workflow: To avoid traditional bolt fixing methods and ensure the fixing speed of the tool body 31, before replacing the tool body 31, the bearing 35 is fitted onto the outside of the shaft roller 32, so that one side of the bearing 35 is in contact with one side of the magnetic retaining ring 33. Under the magnetic attraction of the magnetic retaining ring 33 on the bearing 35, the bearing 35 is temporarily limited. After the bearing 35 is fitted, the tool body 31 on the frame 21 is disassembled, and the hydraulic rod 22 is activated to drive the fixing plate 26 away from the frame 21. As the fixed plate 26 moves, the extension of the limiting telescopic rod 23 fixed on one side causes it to extend. The limiting telescopic rod 23 improves the stability of the fixed plate 26 during movement and also provides support for it. The movement of the fixed plate 26 causes the inner fixed drive device 38 to move, which in turn moves the flange plate 37 and the insertion rod 36. The insertion rod 36 slides out of the insertion hole 34, and at the same time, the upper baffle 27 slides out of the rail groove 25. When the insertion rod 36 moves away from the insertion hole 34, the upper baffle 27 moves away from the arc. At one end of the arc-shaped groove 24, the tool body 31 to be replaced can be directly removed from the inside of the arc-shaped groove 24, and then the new tool body 31 is installed. The bearing 35 installed on the new tool body 31 and the shaft roller 32 is aligned with the arc-shaped groove 24, so that the bearing 35 and the magnetic retaining ring 33 are embedded and installed inside the arc-shaped groove 24. The drive device 38 is started to drive the pre-installed flange plate 37 and the insertion rod 36 to rotate, so that the protruding part of the insertion rod 36 is aligned with the protruding part of the insertion hole 34. Then, the hydraulic rod 2 is used to rotate the tool body 31. 2. The fixed plate 26 is moved. The chamfer at one end of the insertion rod 36 and the chamfer at one end of the insertion hole 34 improve the ease of installation between the insertion rod 36 and the shaft roller 32. When the insertion rod 36 slides into the inside of the insertion hole 34, the upper baffle 27 seals the arc-shaped groove 24. At this time, the replacement of the tool body 31 is completed. When replacing the tool body 31, the device avoids the traditional coupling and bolt fixing method, reduces the difficulty of operation, improves the installation efficiency, and avoids the phenomenon of connection damage caused by bolt fixing.
