[0026] The purpose of the present invention is to provide an adjustable slope cutting saw disc device to solve the problems existing in the above-mentioned prior art. The angles of the first saw disc and the second saw disc are adjustable to achieve precise excavation.

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figure 1-Figure 2As shown, the present invention provides an adjustable slope cutting saw disc device, including a first double-headed telescopic device and a second double-headed telescopic device, the first double-headed telescopic device and the second double-headed telescopic device are arranged parallel to each other, the first telescopic end of the first double-headed telescopic device and the second telescopic end of the first double-headed telescopic device are collinear and arranged away from each other, and the first telescopic end of the second double-headed telescopic device and the second telescopic end of the second double-headed telescopic device are collinear and arranged away from each other.

A first saw disc 9 is fixed to the rotating shaft of the first rotary drive device 7, and the first rotary drive device 7 is used to drive the first saw disc 9 to rotate; a second saw disc 10 is fixed to the rotating shaft of the second rotary drive device 8, and the second rotary drive device 8 is used to drive the second saw disc 10 to rotate.

[0029] In actual use, the first telescopic end of the first double-headed telescopic device and the first telescopic end of the second double-headed telescopic device can be extended and retracted to adjust the inclination angle of the first angle adjustment bracket 5 and the first rotary drive device 7 and the first saw disk 9 above. The second telescopic end of the first double-headed telescopic device and the second telescopic end of the second double-headed telescopic device can be extended and retracted to adjust the inclination angle of the second angle adjustment bracket 6 and the second rotary drive device 8 and the second saw disk 10 above. By adjusting the inclination angle of the first saw disk 9 and the second saw disk 10, the first saw disk 9 and the second saw disk 10 can be cut in different directions, thereby achieving the technical effect of precise cutting and avoiding the occurrence of over-digging and under-digging problems.

[0030] In this embodiment, the first rotary drive device 7 and the second rotary drive device 8 are both existing drive motors, specifically servo motors or stepper motors, etc., as long as they can drive the first saw disc 9 and the second saw disc 10 to rotate.

[0031] In this embodiment, the first double-head telescopic device includes a first hydraulic cylinder 1 and a second hydraulic cylinder 2. The fixed end of the first hydraulic cylinder 1 and the fixed end of the second hydraulic cylinder 2 are fixedly connected, so that the piston rod of the first hydraulic cylinder 1 and the piston rod of the second hydraulic cylinder 2 are arranged oppositely.

[0032] Similarly, the second double-head telescopic device includes a third hydraulic cylinder 3 and a fourth hydraulic cylinder 4. The fixed end of the third hydraulic cylinder 3 and the fixed end of the fourth hydraulic cylinder 4 are fixedly connected, so that the piston rod of the third hydraulic cylinder 3 and the piston rod of the fourth hydraulic cylinder 4 are set oppositely.

[0033] In addition, those skilled in the art may also replace the hydraulic cylinder with an air cylinder or an electric telescopic rod or other equipment to achieve the telescopic effect.

[0034] In this embodiment, the first rotary drive device 7 and the first saw disk 9 are fixedly connected via a first connecting member, thereby achieving the technical effect that the rotation shaft of the first rotary drive device 7 drives the first saw disk 9 to rotate.

[0035] Similarly, the second rotary drive device 8 is fixedly connected to the second saw disc 10 via a second connecting member, thereby achieving the technical effect that the rotation axis of the second rotary drive device 8 drives the second saw disc 10 to rotate.

[0036] In this embodiment, the first connecting member and the second connecting member are both made of steel, preferably thickened steel plates.

[0037] In this embodiment, the first connecting member and the second connecting member are both circular cover structures, which are hemispherical shells. A first connecting hole is provided at the center of the spherical surface of the first connecting member, and a second connecting hole is provided at the center of the spherical surface of the second connecting member.

[0038] In this embodiment, the circular opening surface of the first connecting member is welded to the first saw disk 9, the rotating shaft of the first rotary drive device 7 passes through the first connecting hole, and two first nuts are threadedly connected to the rotating shaft of the first rotary drive device 7. The two first nuts are respectively located on both sides of the first connecting hole. The first connecting member is clamped and fixed by the two first nuts, thereby realizing a fixed connection between the first rotary drive device 7 and the first saw disk 9.

The two second nuts are respectively located on both sides of the second connecting hole. The second connecting member is clamped and fixed by the two second nuts, thereby realizing a fixed connection between the second rotary drive device 8 and the second saw disk 10.

[0040] Of course, in the art, a full welding method can also be used to achieve a fixed connection between the rotating shaft of the first rotary drive device 7 and the first saw disk 9. Specifically, the circular opening surface of the first connecting member is welded to the first saw disk 9, and the first connecting hole is welded to the rotating shaft of the first rotary drive device 7. The second connecting member is connected in the same manner as the first connecting member, so it will not be described in detail.

[0041] In this embodiment, a first washer is provided between the first nut and the first connecting hole, and a second washer is provided between the second nut and the second connecting hole. Providing the first and second washers not only enhances the clamping effect of the first and second nuts but also prevents wear on the first and second connectors.

[0042] In this embodiment, a nozzle is provided on each of the first rotary drive device 7 and the second rotary drive device 8. Specifically, a nozzle bracket is fixed on each of the first rotary drive device 7 and the second rotary drive device 8, and the nozzle is fixed on the nozzle bracket. The nozzle is connected to a water source through a water pipe, and a water pump is provided on the water pipe to provide water supply power. The water source can be a water tank or other water storage container. When actually used, the first saw disc 9 and the second saw disc 10 may generate a large amount of dust when working. The dust may cause damage to the workers and affect work efficiency. At this time, spraying water with a nozzle can effectively remove the dust.

[0043] In this embodiment, the first double-headed telescopic device and the second double-headed telescopic device are both fixed on the same mounting bracket, thereby connecting the first double-headed telescopic device and the second double-headed telescopic device into a whole.

[0044] In this embodiment, in actual use, it is only necessary to fix the mounting bracket to the main arm of the loader. The first hydraulic cylinder 1, the second hydraulic cylinder 2, the third hydraulic cylinder 3 and the fourth hydraulic cylinder 4 are all electrically connected to the controller in the loader and are uniformly controlled by the controller in the loader.

[0045] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
