Description

Technical Field

[0001] The utility model relates to the technical field of dust removal for grinding devices, in particular to a grinding device for mining machinery manufacturing with a dust removal function. Background Art

[0002] Grinding devices are commonly used in mining machinery manufacturing to remove burrs, oxide layers, paint, and other impurities from the surfaces of metal components and provide surface finishing. These devices include electric, pneumatic, and manual types. Electric and pneumatic grinders utilize high-speed rotating grinding wheels or heads to efficiently remove material, while manual grinding tools rely more on the operator's skill and strength. These tools are crucial for improving work efficiency and ensuring the precision and surface quality of mechanical components, thereby enhancing overall performance and extending the service life of the machinery.

[0003] However, the grinding process in mining machinery inevitably generates large amounts of dust and debris. If these tiny particles are not effectively handled, they will pollute the work environment, endangering not only the health and safety of operators but also the surrounding environment. Currently, many mining machinery manufacturing sites lack efficient dust collection equipment, making it difficult to effectively remove the dust generated by grinding. This not only violates safety and environmental regulations, but also poses a potential risk to worker health.

[0004] Therefore, to ensure a safe and clean working environment, we urgently need to introduce an advanced dust collection system. This system can effectively reduce the dust generated during the grinding process, reduce its harm to the environment and human health, and provide a safer and cleaner working environment for mining machinery manufacturing. Utility Model Content

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 - Figure 4 As shown, this equipment is a grinding device designed specifically for mining machinery manufacturing and features efficient dust removal. The main structure of the device is composed of a support frame 1, whose stability provides a solid foundation for the entire device. A second rotating shaft 4 is cleverly positioned in the upper right corner of the support frame 1. This design enables the drive device 5 to smoothly connect and drive the entire grinding system. The remaining three corners of the support frame 1—the upper left, lower left, and lower right corners—are equipped with a third rotating shaft 6, a fourth rotating shaft 7, and the first rotating shaft 3, respectively. These four rotating shafts collectively support the grinding equipment designed specifically for mining machinery manufacturing, ensuring a smooth grinding process.

[0026] Furthermore, in order to optimize the dust removal effect, a mounting seat 2 is specially provided at the lower end of the support frame 1. This mounting seat 2 is cleverly located directly below the polishing belt 8, facilitating the subsequent dust removal steps. On the end face of the mounting seat 2, a connecting seat 9 is installed. This design not only enhances the stability of the device but also provides an installation basis for the subsequent dust removal components.

[0027] At the front end of the connecting seat 9, a first arc-shaped strip 13 and a second arc-shaped strip 14 are innovatively provided. These two arc-shaped strips are arranged with staggered heights, forming a unique spatial structure. Even more ingeniously, cleaning brushes 15 are equipped at the ends of these two arc-shaped strips. These brushes can closely contact the polishing belt 8, thereby removing the generated dust in real time during the polishing process.

[0028] To further improve the dust removal efficiency, a screw tube 10 is designed at the lower part of the end face of the connecting seat 9. The screw tube 10 is integrally formed with the connecting seat 9, ensuring the stability of the structure. An adjustable distance screw 11 is inserted into the screw tube 10. By rotating the adjustable distance screw 11, we can easily adjust the position of the collection cloth bag 12. This design enables the collection cloth bag 12 to be placed at the position of the cleaning brush 15 or the fourth rotating shaft 7 according to needs, so as to collect the dust generated during the cleaning process and the debris generated during the polishing operation respectively.

[0029] In addition, the mounting seat 2 and the support frame 1 are connected by bolts, which not only ensures the stability of the connection but also facilitates subsequent maintenance and replacement. Alignment round holes are opened on the mounting seat 2 and the connecting seat 9 to facilitate the passing and fastening of bolts. The first arc-shaped strip 13 and the second arc-shaped strip 14 are fixed to the connecting seat 9 by welding, ensuring the firmness and stability of the structure.

[0030] The design inspiration of the first arc-shaped strip 13 and the second arc-shaped strip 14 comes from the shape of "丿". This design is not only beautiful and generous but also effectively supports and adjusts the cleaning brush 15 in terms of function. The arc-shaped strip consists of a tail bending strip and a top elastic strip. By adjusting the bending degree of the tail bending strip, we can change the curvature of the top elastic strip, thereby precisely controlling the contact force between the cleaning brush 15 and the polishing belt 8.

[0031] To ensure the stability and durability of the cleaning brush 15, multiple cleaning brushes​​During the grinding process, the drive unit 5 connects to and drives the grinding system via the second shaft 4. Together, the four shafts support the grinding equipment, ensuring a smooth grinding process. During the grinding process, the cleaning brushes 15 on the first and second curved strips 13, 14 come into close contact with the grinding belt 8, removing any dust that is generated.

[0033] The cleaning process involves dust collection, which is achieved through a mounting base 2 positioned directly below the sanding belt 8. A connecting base 9 is attached to the end face of the mounting base 2. The first and second curved strips 13 and 14 are equipped with cleaning brushes 15, which remove dust during the sanding process. A solenoid 10 is integrally formed with the connecting base 9. An adjustable pitch screw 11 is inserted into the solenoid 10. Rotating the pitch screw 11 adjusts the position of a collection bag 12, which can be positioned either on the cleaning brush 15 or on the fourth shaft 7 to collect dust and debris generated during the cleaning and sanding operations, respectively.

[0034] The dust collection process starts with the dust generated by the grinding belt 8. The dust is guided to the collecting bag 12 through the contact and removal of the cleaning brush 15. The adjustment of the pitch screw 11 ensures that the collecting bag 12 can effectively collect dust. The replacement and maintenance of the collecting bag 12 are achieved through the bolt connection between the mounting base 2 and the support frame 1, which is convenient for subsequent maintenance and replacement. The first arc strip 13 and the second arc strip 14 are fixed to the connecting base 9 by welding to ensure the firmness and stability of the structure. The design of the arc strip allows the curvature of the top elastic strip to be changed by adjusting the bending degree of the tail bending strip, so as to achieve precise control of the contact force between the cleaning brush 15 and the grinding belt 8. The cleaning brush 15 is fixed to the rubber strip by hot melting, and then glued to the top of the first arc strip 13 or the second arc strip 14, which simplifies the installation process and improves the service life and cleaning effect of the cleaning brush 15.
