[0027] Embodiment 1

[0028] Referring to Figures 1-2 A splitting trolley comprises a trolley body and a mechanical arm mounted on the trolley body. The mechanical arm is used for operating splitting and drilling operations. A mounting frame 1 is mounted on the mechanical arm. No. 1 mounting plate 2 and No. 2 mounting plate 22 are respectively slidably arranged on the top of the mounting frame 1. The two mounting plates can slide along the top of the mounting frame 1 to adapt to different operation requirements.

[0029] Referring to Figures 3-4 A drilling machine is arranged on the top of No. 1 mounting plate 2. The drilling machine comprises a motor 6 and a drill bit 3. The motor 6 is fixedly arranged on the top of No. 1 mounting plate 2, and the drill bit 3 is located on one side of the motor 6. The output shaft of the motor 6 is connected with the drill bit 3 through a mounting mechanism. The mounting mechanism comprises a vertical plate 8 fixedly arranged on the top of No. 1 mounting plate 2. A round plate 11 is rotatably arranged in the vertical plate 8, and the output end of the motor 6 is fixedly connected to one side of the round plate 11. A polygonal block 9 is fixedly arranged on one side of the round plate 11, and one end of the drill bit 3 is provided with a polygonal groove 18 matched with the polygonal block 9.

[0030] In addition, the mounting mechanism further comprises a plurality of clamping plates 16, a plurality of sliding grooves 10 are arranged on one side of the round plate 11, and one end of each of the plurality of clamping plates 16 is slidably arranged in the plurality of sliding grooves 10. A plurality of clamping grooves 23 are arranged on the outer wall of the drill bit 3, and the other end of each of the plurality of clamping plates 16 is matched with the clamping grooves 23, so as to fix the drill bit 3. The sliding grooves 10 are arranged in a ring shape at equal intervals, so as to ensure that the clamping plates 16 can be uniformly distributed around the round plate 11.

[0031] The inner part of the sliding groove 10 is fixedly provided with a round rod 17, the clamping plate 16 is slidably sleeved on the outer wall of the round rod 17, the outer wall of the round rod 17 is sleeved with a tension spring, and the two ends of the tension spring are fixedly arranged on the inner wall of one side of the sliding groove 10 and one side of the clamping plate 16 respectively.

[0032] The mounting mechanism further comprises a fixing cylinder 14. The fixing cylinder 14 is sleeved on the outer wall of the drill bit 3, one side of the outer wall of the fixing cylinder 14 is fixedly provided with a limiting rod 13, and the other side is rotatably provided with a threaded rod 15. The two ends of one side of the circular plate 11 are respectively provided with a limiting hole 7 and a threaded hole 12, the limiting rod 13 can be slidably extended into the inner part of the limiting hole 7, and one end of the threaded rod 15 can be bolted into the inner part of the threaded hole 12. By rotating the threaded rod 15, the fixing cylinder 14 can be moved, thereby moving the plurality of clamping plates 16 to be clamped into the inner part of the clamping groove 23 for fixation.

[0033] Specifically, rotating the threaded rod 15 can drive the fixing cylinder 14 to displace along the limiting rod 13. When the fixing cylinder 14 is separated from the outer wall of the clamping plate 16, the clamping plate 16 will be driven by the force of the tension spring to move outward, and one end of the clamping plate 16 will be separated from the inner part of the clamping groove 23, thereby releasing the fixed state of the drill bit 3. Then, the drill bit 3 can be directly pulled out for replacement. When a new drill bit 3 is installed, the fixing cylinder 14 is first passed through, then the polygonal groove 18 and the polygonal block 9 are aligned and inserted, and then the threaded rod 15 is rotated. The threaded rod 15 will drive the fixing cylinder 14 to move, and the inner wall of the fixing cylinder 14 will touch the arc surface of the clamping plate 16 to press the clamping plate 16 inward, so that one end of the clamping plate 16 is inserted into the inner part of the clamping groove 23, thereby fixing the drill bit 3. Subsequently, the driving motor 6 drives the circular plate 11 to rotate, and the circular plate 11 drives the drill bit 3 to rotate through the polygonal block 9 and the clamping plate 16, thereby realizing the rotation of the drill bit 3.

[0034] The present application can be used in the field of engineering machinery, and can also be used in other fields applicable to the present application.
