Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figures 1-5In this embodiment of the utility model, a hydraulic grooving machine includes a housing 1. A mounting base 2 is rotatably connected through the middle of the housing 1. A rotating shaft 3 is rotatably connected through the edge of the mounting base 2. A grooving cutter 4 is fixedly mounted on the rotating shaft 3 and located inside the mounting base 2. The mounting base 2 has a notch adapted to the grooving cutter 4. A motor 5 is fixedly mounted on the end of the mounting base 2 corresponding to the end of the rotating shaft 3. The output end of the motor 5 is fixedly mounted on the end of the rotating shaft 3 corresponding to the output end of the rotating shaft 3. A lever arm 6 is rotatably mounted at the center of both ends of the mounting base 2. The top surface of the housing 1 is equipped with a pushing mechanism corresponding to the actuating arm 6. A baffle 8 is fixedly connected to one side of the mounting base 2 corresponding to the actuating arm 6. An arc-shaped guide rod 9, concentrically arranged with the mounting base 2, slides through the baffle 8. The baffle 8 has holes for the arc-shaped guide rod 9 to pass through and slide. One end of the arc-shaped guide rod 9 is fixedly connected to the actuating arm 6, and the other end is fixedly connected to a limit block, which fits against the baffle 8. Springs 10 are fitted on the outer sides of the arc-shaped guide rod 9, with both ends of the springs 10 abutting against the baffle 8 and the actuating arm 6 respectively. A switch 22 and a mobile power supply 7 are fixedly installed on the housing 1. The motor 5 is electrically connected to the switch 22 via wires, and the switch 22 is electrically connected to the mobile power supply 7 via wires.

[0023] Motor 5 drives shaft 3 to rotate, which in turn drives grooving cutter 4 to rotate. Through the pushing mechanism, it pushes actuating arm 6. Actuating arm 6, through spring 10 and arc-shaped guide rod 9, elastically pushes mounting base 2 to rotate, thereby causing grooving cutter 4 to rotate eccentrically and insert into the ground for grooving.

[0024] The actuating arm 6 pulls the baffle 8 back through the arc-shaped guide rod 9 and the limiting block to form the maximum support distance.

[0025] The actuating arm 6 provides elastic support to the baffle 8 via the spring 10. When the actuating arm 6 is actuated, it pushes the mounting base 2 to rotate, causing the grooving cutter 4 to press against the ground. When the ground is hard, the spring 10 can form a compression buffer to avoid rigid collision contact and provide protection. This effectively prevents the grooving cutter 4 from being damaged by direct pressure during construction on hard ground, thus extending the service life of the grooving cutter 4.

[0026] Casters 11 are fixedly installed at the four corners of the bottom surface of housing 1, and a push handle 12 is fixedly installed on the top of the rear surface of housing 1.

[0027] The casters 11 and push handle 12 make it easy to push the hydraulic trenching machine.

[0028] The pushing mechanism includes a push rod 13, a guide rod 14, and a threaded rod 15. The push rod 13 is disposed between the actuating arms 6. The top surface of the housing 1 is fixedly connected to the two ends of the guide rod 14 and the threaded rod 15. Two guide rods 14 are symmetrically arranged, and the threaded rod 15 is disposed between the two guide rods 14 and arranged in parallel.

[0029] The outer side of the guide rod 14 is fitted with a sliding sleeve 17 that is adapted to it. The sliding sleeve 17 is fixedly inserted through the push rod 13. The two ends of the guide rod 14 are fixedly connected to the extension side plate 16.

[0030] The threaded rod 15 is rotatably connected to the extension side plate 16. One end of the threaded rod 15 is fixedly connected to a handwheel 18. The outer side of the threaded rod 15 is threadedly connected to a matching threaded sleeve 19. The threaded sleeve 19 is fixedly connected to the push rod 13.

[0031] Both ends of the push rod 13 are fixedly connected to movable seats 20. The actuating arm 6 is provided with a sliding groove 21 that matches the movable seat 20. The movable seat 20 is inserted into the sliding groove 21 and is movably connected.

[0032] Rotating the threaded rod 15 by handwheel 18 drives the push rod 13 to move along the sliding direction of the sliding sleeve 17 and guide rod 14 through the engagement of the threaded sleeve 19. The push rod 13 pushes the actuating arm 6 through the movable seat 20 and the sliding groove 21, thereby causing the mounting seat 2 to rotate, which in turn drives the grooving knife 4 to rotate eccentrically, so that the grooving knife 4 is inserted into the ground and the insertion depth is controlled.

[0033] The working principle of this utility model is as follows: In use, first push the hydraulic grooving machine to the area where hydraulic construction is needed, so that the grooving blade 4 corresponds to the hydraulic grooving position. At this time, start the motor 5 by switching on the switch 22. The motor 5 drives the grooving blade 4 to rotate through the rotating shaft 3. Further, rotate the threaded rod 15 by the handwheel 18, thereby driving the push rod 13 to move along the sliding direction of the sliding sleeve 17 and the guide rod 14 through the cooperation of the threaded sleeve 19. The push rod 13 pushes the actuating arm 6 through the movable seat 20 and the sliding groove 21. The actuating arm 6 elastically pushes the mounting base 2 to rotate through the spring 10 and the arc-shaped guide rod 9. When the actuating arm 6 is actuated, the grooving blade 4 rotates eccentrically and inserts into the ground to perform grooving. When the ground is hard, the spring 10 can form a compression buffer to avoid rigid collision contact and achieve a protective effect.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
