Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and more specifically to a high wear-resistant cutting tool for mining. Background Technology

[0002] Mining picks are critical cutting tools specifically designed for mining operations in coal mines, metal mines, and other similar facilities. Their structure typically consists of a carbide tip, an alloy steel tooth body, and connecting components. These components work together to ensure the pick's high strength, high wear resistance, and high impact toughness. The primary function of mining picks is to cut and crush hard materials such as rock and coal seams during the mining process. Through rotation or impact, the picks efficiently crush materials, thereby advancing mining operations. In coal mining, picks are widely used on the drums of coal mining machines to cut coal seams; in metal mines, they are commonly used in tunneling machines and crushers to crush hard ores.

[0003] Mining equipment with cutting tools installed is prone to wear due to the significant friction generated when it comes into contact with the coal seam. Therefore, a new technical solution is needed to address this issue. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a high wear-resistant cutting tool for mining, comprising: an outer disk 1, wherein a plurality of fixed seats 2 are provided at the edge and outer surface of the outer disk 1, and a cutting tool body 3 is provided inside the fixed seats 2; an inner disk 4 is provided on the surface of the outer disk 1, and a mounting plate 5 is provided inside the inner disk 4; the mounting plate 5 is fixed to the inner disk 4 by bolts; auxiliary teeth 6 and double-headed teeth 7 are provided on the surface of the mounting plate 5; and a mounting seat 8 is provided on the side of the outer disk 1. Connected to the power actuator of the coal mining machine, the fixed base 2 has an internal mounting groove 9, and the cutting tooth body 3 includes a mounting column 13 inserted into the mounting groove 9. A connecting seat 15 is provided on the upper part of the mounting column 13, and a connecting column 16 is provided on the upper part of the connecting seat 15. A tooth body 17 is provided on the upper part of the connecting column 16, and the tooth body 17 and the connecting column 16 are smoothly integrated. Several sets of fixed bases 2 are provided at the edge and outer surface of the outer plate 1, and the cutting tooth body 3 is provided inside the fixed base 2. The outer disc 1 and the cutting tooth body 3 can be arranged parallel to each other or staggered to avoid direct contact between the outer disc 1 and the coal seam, thereby reducing friction on the outer disc 1 and improving its service life. An inner disc 4 is provided on the surface of the outer disc 1, and a mounting plate 5 is provided inside the inner disc 4. The mounting plate 5 is fixed to the inner disc 4 by bolts. Auxiliary teeth 6 and double-headed teeth 7 are arranged circumferentially on the surface of the mounting plate 5. During rotation, these teeth can break up the coal seam, thus avoiding friction from the side. The side is provided with a mounting base 8, which is connected to the power actuator of the coal mining machine. The inside of the fixed base 2 is provided with a mounting groove 9, and the cutting tooth body 3 includes a mounting column 13 inserted into the mounting groove 9. A connecting base 15 is provided on the upper part of the mounting column 13, and a connecting column 16 is provided on the upper part of the connecting base 15. A tooth body 17 is provided on the upper part of the connecting column 16, and the tooth body 17 and the connecting column 16 are smoothly integrated. This setting not only increases the stability of the tooth body 17 installation, but also facilitates the disassembly and replacement of the cutting tooth body 3.

[0020] Further improvements, such as Figure 1As shown: The fixed seat 2 and the cutting tooth body 3 can be arranged parallel to each other or staggered. The staggered and parallel distribution of the cutting tooth body 3 increases the density between them, avoids the outer plate 1 from directly contacting the coal seam, reduces the friction of the outer plate 1, and thus improves the service life of the outer plate 1.

[0021] Further improvements, such as Figure 4 As shown: The bottom of the mounting groove 9 is provided with a plug-in post 10 and the inside of the mounting post 13 is provided with a plug-in groove 14. The plug-in post 10 and the plug-in groove 14 are interlocked with each other. The plug-in structure enhances the connection stability between the cutting tooth body 3 and the outer disk 1, and ensures the firmness of the cutting tooth in the mining process.

[0022] Further improvements, such as Figure 4 As shown: The bottom of the mounting column 13 is provided with a slot 12 and the inside of the mounting slot 9 is provided with a matching snap ring 11. The cooperation of the slot 12 and the snap ring 11 further strengthens the connection between the cutting tooth body 3 and the outer disk 1, preventing the cutting tooth from loosening or falling off during the mining process.

[0023] Further improvements, such as Figure 4 As shown: The surface of the tooth body 17 is provided with several sets of spirally distributed protrusions 18 and the protrusions 18 are welded and fixed to the tooth body 17. The protrusions 18 are distributed in a spiral structure. The spirally distributed protrusions 18 increase the contact area and friction between the tooth body 17 and the coal seam, improve the cutting efficiency of the cutting tooth, and the design of the protrusions 18 also helps to remove chips and reduce wear, thus extending the service life of the cutting tooth.

[0024] Further improvements, such as Figure 2 As shown: The cutting tooth body 3 is set at an inclination. The inclination of the cutting tooth body 3 can better adapt to the inclination angle of the coal seam and improve the accuracy and efficiency of cutting.

[0025] Working principle: First, the high wear-resistant cutting tooth equipment for mining is connected to the power actuator of the coal mining machine through the mounting base 8 to ensure that the equipment can receive power and start normally. At this time, the outer disk 1, the inner disk 4, and the cutting tooth body 3 installed on them are all in a ready state. Under the action of the coal mining machine, the outer disk 1 begins to rotate, driving the cutting tooth body 3 installed on its edge and outer surface to cut the coal seam. The tooth body 17 of the cutting tooth body 3 contacts the coal seam and breaks the coal seam by rotation and impact. During the cutting process, since the cutting tooth body 3 is set at an angle and the fixing seat 2 and the cutting tooth body 3 can be set parallel or staggered to each other, the outer plate 1 can be effectively prevented from directly contacting the coal seam, thereby reducing friction and wear on the outer plate 1. At the same time, the spirally distributed protrusions 18 on the surface of the tooth body 17 also play a role in reducing friction and chip removal, further protecting the cutting tooth and the coal seam. When the cutting tooth body 3 is worn to a certain extent, the cutting tooth body 3 can be removed from the mounting slot 9 for replacement by disassembling the connecting seat 15 and connecting post 16 on the mounting post 13. Due to the use of the plug-in structure and the design of the slot 12 and the snap ring 11, the disassembly and replacement process of the cutting tooth body 3 is simple and quick, improving maintenance efficiency.
