Description

Technical Field

[0001] This utility model relates to the field of pulverizer technology, and in particular to a quick blade changing device for a modular media pulverizer. Background Technology

[0002] A crusher is a machine that crushes large solid raw materials to the required size. A crusher consists of coarse crushing, fine crushing, and pneumatic conveying devices. It achieves the purpose of crushing by high-speed impact and uses wind power to produce powder in one step, eliminating the traditional screening process. It is mainly used in mining, building materials and other industries.

[0003] Currently, modular media require pulverizers for crushing. Existing pulverizers require replacement of their blades after prolonged use, and these blades are typically installed using screws. This installation method necessitates numerous screw rotations, reducing blade replacement efficiency. Furthermore, current pulverizers crush modular media at high speeds, resulting in inconsistent particle sizes and reduced crushing quality. Therefore, we propose a rapid blade changing device for modular media pulverizers to address these issues. Utility Model Content

The crushing component 3 includes a power motor 301. The output end of the power motor 301 is connected to a drive gear 302. A sealed bearing 30 is embedded on one side of the crushing box 1. 3. The inner ring of the sealed bearing 303 is connected to the driven gear 304, and the outer surface of each crushing blade 4 is connected to the transmission gear 305. The mounting base 201 is adapted to the fixed base 205. The T-shaped limit rod 203 is slidably connected to the sliding hole 202. The rebound force of the telescopic spring 204 allows for convenient and quick replacement of the crushing blade 4 and reduces the workload of installation. The rotation of the power motor 301 can drive the drive gear 302 to rotate, and the drive gear 302 meshes with the driven gear 304. The drive gear 302 meshes with a transmission gear 305, and the driven gear 304 meshes with a transmission gear 305. The use of the sealed bearing 303 and the bearing housing 207 allows the two crushing blades 4 to approach each other for uniform crushing of the modular media. This not only improves the installation efficiency of the crushing blades 4 but also improves the crushing quality.

[0024] Two support legs 6 are connected to one side of the crushing box 1. Each support leg 6 has two mounting holes on one side. The support legs 6 and mounting holes can be used to easily support and fix the equipment. Two U-shaped positioning frames 7 are connected to the outer surface of the crushing box 1.

[0026] The working principle of this utility model is as follows:

[0027] First, the support leg 6 can be fixed to the foundation using the mounting holes and screws as needed, and the electrical components can be connected to the power supply. If the crusher blade 4 needs to be replaced, pull the sealing door 8 to separate it from the U-shaped positioning frame 7. Simultaneously, pulling the T-shaped limit rod 203 will stretch the telescopic spring 204, releasing the T-shaped limit rod 203 from limiting the positioning hole 206. Then, remove the crusher blade 4 and take out the new crusher blade 4. Place the fixing seat 205 inside the mounting seat 201, and simultaneously release the T-shaped limit rod 203. The rebound force of the telescopic spring 204 will allow the T-shaped limit rod 203 to limit the crusher blade 4. After the crusher blade 4 is installed, its drive gear 30... 2 meshes with a transmission gear 305, and then the driven gear 304 meshes with the driving gear 302, and the driven gear 304 meshes with a transmission gear 305. At the same time, the sealing door 8 is reset, and the raw material is put into the feeding hopper 10. Next, the rotation of the power motor 301 enables the driving gear 302 to drive a transmission gear 305 and a crushing blade 4 to rotate. With the driving gear 302 meshing with the driven gear 304 and the driven gear 304 meshing with a transmission gear 305, the two crushing blades 4 can rotate towards each other and crush the medium. Finally, the crushed medium is removed from the feeding plate 5. The above is the entire usage process of this utility model.
