Description

Technical Field

[0001] This utility model relates to the field of disc data technology, specifically to a disc data structure. Background Technology

[0002] As a common cutting tool, the circular saw is widely used in agriculture, forestry, construction and other fields, and plays an important role, especially in soil cutting and wood processing.

[0003] However, since traditional circular saws mostly use a forward cutting method (i.e., the vehicle's direction of travel is the same as the direction of the cutter head rotation), this method often results in the soil not being discharged in time when cutting the soil, causing the saw to get stuck. This not only increases the cutting resistance but also consumes more power. In addition, the saw teeth of traditional circular saws are mostly straight and closely arranged. This structure easily increases the contact area between the saw teeth and the soil, further increasing the cutting resistance and reducing the cutting efficiency. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a circular saw structure to solve the problem mentioned in the background art, where circular saws often employ a forward cutting method (i.e., the vehicle's travel direction is the same as the cutter head's rotation direction). This method often results in the soil not being discharged in time when cutting soil, causing saw jamming, which not only increases cutting resistance but also consumes more power. Furthermore, the saw teeth of traditional circular saws are mostly straight and closely arranged. This structure easily increases the contact area between the saw teeth and the soil, further increasing cutting resistance and reducing cutting efficiency.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a disk-shaped data structure, comprising:

[0008] The disc shell has a reverse-cut design, and the outer ring of the disc shell is evenly distributed with serrations. The serrations adopt a bent staggered tooth structure and a structure with few teeth and long teeth. The number of serrations is 14 to 18.

[0009] An arc-shaped groove is provided between the saw teeth and the outer shell of the disc. The outer surfaces of the saw teeth are all curved, and the inner sides of the saw teeth are all concave arc-shaped surfaces. The arc-shaped groove is opened on the surface of the outer shell of the disc. One side of the arc-shaped groove is connected to the inner side of the saw teeth at the corresponding position, and the other side of the arc-shaped groove is connected to the outer ring of the saw teeth at the corresponding position.

[0010] Preferably, the inner walls of the circular grooves on the surface of the disc shell are all equipped with sound-absorbing rubber rings, which can absorb high-frequency vibration sound waves during cutting to reduce vibration and noise.

[0011] Preferably, threaded holes are evenly distributed in the center of the surface of the disc shell, and the threaded holes are all located outside the mounting holes in the center of the disc shell, so that the disc can be installed through the threaded holes.

[0012] Preferably, the inner ring of the surface of the disc shell is evenly provided with first heat dissipation holes, which are located between the sound-absorbing rubber ring and the threaded hole. The first heat dissipation holes can be used to dissipate heat from the mounting part of the disc.

[0013] Preferably, the outer surface of the disc shell is uniformly provided with second heat dissipation holes. The second heat dissipation holes are located between the saw teeth and the noise-absorbing rubber ring. The cutting part of the disc saw can be cooled through the second heat dissipation holes, thus extending the life of the saw teeth.

[0014] Beneficial effects

[0015] Compared with the prior art, the present invention provides a disc-shaped data structure, which has the following advantages:

[0016] The circular saw structure features a reverse-cutting design in its outer shell: the circular saw rotates in the opposite direction to the vehicle's travel direction, enabling timely removal of cut soil and significantly reducing power consumption. The saw teeth employ a bent, staggered tooth structure, which reduces resistance to the saw teeth and also serves to remove soil. The combination of fewer and longer teeth reduces the contact area between the saw teeth and the soil, further reducing resistance and collectively improving the cutting efficiency and stability of the circular saw.

Figure 1 Including the disc casing 1, please refer to Figure 3 The outer shell 1 of the disc is designed with a reverse cut. The outer ring of the outer shell 1 is evenly distributed with serrations 2. The serrations 2 adopt a bent staggered tooth structure, which can reduce the resistance of the serrations 2 and play the role of soil removal. The serrations 2 adopt a structure of few teeth and long teeth, which can reduce the contact area between the serrations 2 and the soil, thereby reducing the resistance of the serrations 2. The number of serrations 2 is 14 to 18.

[0023] Please see Figure 2 An arc-shaped groove 3 is provided between the saw teeth 2 and the disc shell 1. The outer surface of the saw teeth 2 is all curved, and the inner side of the saw teeth 2 is all concave arc-shaped. The arc-shaped groove 3 is opened on the surface of the disc shell 1. One side of the arc-shaped groove 3 is connected to the inner side of the saw teeth 2 at the corresponding position, and the other side of the arc-shaped groove 3 is connected to the outer ring of the saw teeth 2 at the corresponding position.

[0024] The circular saw uses high-strength spring steel 65Mn as the cutter body, with tungsten-cobalt cemented carbide tips welded to it or laser-coated tungsten alloy on the cutting edge, achieving the characteristics of sharpness, wear resistance and impact resistance.

[0025] The reverse cutting design of the disc shell 1 is as follows: the rotation direction of the disc is opposite to the direction of vehicle travel, which can promptly discharge the cut soil and significantly reduce power consumption. The saw teeth 2 adopt a bent staggered tooth structure, which can reduce the resistance of the saw teeth 2 and play a role in soil discharge. The saw teeth 2 adopt a structure of fewer teeth and longer teeth, which can reduce the contact area between the saw teeth 2 and the soil, further reducing the resistance of the saw teeth 2, and together improving the cutting efficiency and stability of the circular saw.

[0026] Please see Figure 1 The inner wall of the circular groove on the surface of the disc shell 1 is equipped with a sound-absorbing rubber ring 4. The sound-absorbing rubber ring 4 can absorb the high-frequency vibration sound waves during cutting to reduce vibration and noise.

[0027] The surface of the disc housing 1 is evenly provided with threaded holes 5. The threaded holes 5 are all located outside the mounting holes in the center of the disc housing 1. The disc can be installed through the threaded holes 5.

[0028] The inner ring of the disc shell 1 is evenly provided with first heat dissipation holes 6. The first heat dissipation holes 6 are located between the sound-absorbing rubber ring 4 and the threaded hole 5. The first heat dissipation holes 6 can dissipate heat from the mounting part of the disc.

[0029] The outer surface of the disc shell 1 is evenly provided with second heat dissipation holes 7. The second heat dissipation holes 7 are located between the saw teeth 2 and the noise-absorbing rubber ring 4. The cutting part of the disc saw can be cooled through the second heat dissipation holes 7, which extends the life of the saw teeth 2.

[0030] In operation, this design features: First, the disc outer shell 1 is designed with reverse cutting so that the disc rotates in the opposite direction to the vehicle's travel direction, allowing for timely removal of cut soil and significantly reducing power consumption. Second, the saw teeth 2 employ a bent, staggered tooth structure, which reduces resistance and facilitates soil removal. The combination of fewer and longer teeth in the saw teeth 2 reduces the contact area between the saw teeth and the soil, further lowering resistance and improving the cutting efficiency and stability of the disc saw. Finally, the first heat dissipation hole 6 provides heat dissipation for the mounting area of ​​the disc saw, while the second heat dissipation hole 7 provides heat dissipation for the cutting portion, extending the lifespan of the saw teeth 2.
