DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] The implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0024] Embodiment 1:

[0025] according to Figure 1-3 As shown, a modified cutting machine comprises a base frame 1, on the surface of which a water tank and a motor 2 are mounted;

[0026] It also includes a main shaft 11, a hexagonal prism 10, a secondary shaft 9, an adjustment mechanism and a positioning mechanism;

[0027] The output shaft of the motor 2 is connected to the main shaft 11 through a belt, a secondary shaft 9 is provided on one side of the main shaft 11, one end of the secondary shaft 9 is fixedly connected to a hexagonal prism 10, the hexagonal prism 10 is slidably connected to the main shaft 11 through an adjustment mechanism, the other end of the secondary shaft 9 is fixedly connected to a blade 7, a vertical plate 12 is fixedly connected to the surface of the base frame 1, the vertical plate 12 is sleeved on the surface of the main shaft 11, the surfaces of the main shaft 11 and the secondary shaft 9 are both sleeved with a connecting piece 8, and the main shaft 11 passes through the vertical plate 12 and is rotatably connected through the connecting piece 8;

[0028] A vertical plate 12 is provided on the connecting member 8 on the surface of the secondary shaft 9, and a protective cover 3 is fixedly connected to the other end of the vertical plate 12, and the protective cover 3 is used to prevent debris from splashing;

[0029] The connecting member 8 is a ball bearing, and the connecting plate 5 is fixedly connected to the outer ring of the ball bearing on the surface of the secondary shaft 9. The ball bearing can not only ensure that the main shaft 11 rotates in the vertical plate 12, but also reduce friction;

[0030] During operation, when the cutting machine is used to cut in a narrow space, the slice can be extended through the retractable main shaft 11 and the secondary shaft 9, so that the cutting work can be performed at the position that the cutting machine cannot reach. The extension length of the secondary shaft 9 can be adjusted through the adjustment mechanism so that it can adapt to more terrains, which greatly improves the applicability of the cutting machine during use. At the same time, the ball bearing can not only ensure that the main shaft 11 rotates in the vertical plate 12, but also reduce friction, reduce wear, and increase the service life of the main shaft 11 and the secondary shaft 9. The protective cover 3 can prevent mud and debris from splashing and affecting the operation of the staff. The water tank and the water pipe can be used to cool the blade 7 to avoid damage to the blade 7 due to excessive temperature during cutting.

[0031] The adjustment mechanism includes a threaded rod 13, one end of which is fixedly connected to the connecting plate 5, and the other end passes through the vertical plate 12 for sliding connection. The surface of the threaded rod 13 is threadedly connected with an adjusting nut 17, and two adjusting nuts 17 are provided, and are symmetrically arranged with the central bearing of the vertical plate 12. A protective sleeve 4 is provided between the vertical plate 12 and the connecting plate 5. The protective sleeve 4 is an elastic bellows, and the protective sleeve 4 is sleeved on the surface of the threaded rod 13. One end of the protective sleeve 4 is fixedly connected to the surface of the connecting plate 5, and the other end surface is fixedly connected with a magnetic ring 18. The vertical plate 12 is made of a magnetically absorbable material, and an elastic bellows is also provided on the other side of the vertical plate 12;

[0032] During operation, when adjusting the extension length of the secondary shaft 9, the adjusting nut 17 is rotated so that the adjusting nut 17 drives the threaded rod 13 to move away from the main shaft 11. After the blade 7 reaches the specified position, the adjusting nuts 17 on both sides of the vertical plate 12 are tightened at the same time to fix the position of the blade 7. Through thread adjustment, the movement position of the blade 7 can be made more accurate to improve the position accuracy during cutting. The threaded rod 13 is protected by an elastic bellows to prevent mud and debris from covering the surface of the threaded rod 13, which is easy to cause corrosion to it, causing rust over time and affecting adjustment. At the same time, the bellows can be disassembled through the magnetic ring 18 to facilitate the screwing of the adjusting nut 17.

[0033] The positioning structure includes a support plate 6, which is fixedly connected to one side of the vertical plate 12. A sliding shaft 15 is slidably connected to the surface of the support plate 6 through a spring. One end of the sliding shaft 15 passes through the support plate 6 and is slidably connected to the hard bellows, and a clamping plate 16 is fixedly connected to the end. The clamping plate 16 is close to the side of the threaded rod 13 and is provided with a thread groove corresponding to the surface of the threaded rod 13. The cross section of the sliding shaft 15 is rectangular, and the longitudinal section of the clamping plate 16 is arc-shaped. A notch 14 is provided on the surface of the vertical plate 12 relative to the position of the magnetic ring 18;

[0034] During operation, after the threaded rod 13 is adjusted to a suitable position, the sliding shaft 15 driven by the spring slides downward, and at the same time drives a clamping plate 16 with a threaded groove arc on one side to fit on the surface of the threaded rod 13, so as to position the lateral sliding of the threaded rod 13, so as to avoid the vibration generated by the cutting machine during operation causing the secondary shaft 9 to shake, thereby causing the blade 7 to deform and damage the blade 7. The rectangular cross-section can ensure that the sliding shaft 15 can only move up and down but not rotate, so that the clamping plate 16 can fit on the surface of the threaded rod 13, and the protection effect of the threaded rod 13 can be improved through the notch 14.

[0035] Embodiment 2:

[0036] like Figure 4-5 As shown, in contrast to Example 1, as another embodiment of the present utility model, a group of connecting rods 20 are fixedly connected to the surface of one end of the secondary shaft 9 that passes through the blade 7, a main magnetic block 23 is fixedly connected to the surface of the connecting rod 20, a sleeve shaft 19 is fixedly connected to the surface of the protective cover 3, a secondary magnetic block 21 is slidably connected to the sleeve shaft 19 through a spring, the secondary magnetic block 21 and the main magnetic block 23 are of the same polarity and repel each other, and a rubber ring 22 is fixedly connected to the sleeve shaft 19;

[0037] During operation, when the blade 7 rotates, the connecting rod 20 is driven to rotate. At the same time, when the main magnetic block 23 on the surface of the connecting rod 20 rotates to the position of the auxiliary magnetic block 21, the auxiliary magnetic block 21 will hit the protective cover 3 due to the principle of like charges repelling each other. The vibration generated by the protective cover 3 will shake off the impurities adhered to the inner wall, thereby avoiding blockage over time and increasing the resistance of the blade 7 when rotating. The rubber ring 22 can limit the reset of the auxiliary magnetic block 21 after it hits the protective cover 3, reduce the reset speed, and reduce the frequency of the impact of the auxiliary magnetic block 21. Because the blade 7 rotates at a high speed, a too high frequency may damage the auxiliary magnetic block 21.

Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
