[0024] There are two track grooves 6 , which are symmetrically distributed about the central axis of the mounting plate 4 , so that the device can remain stable when moving.

[0025] See also Figure 2-3 In order to support the position of the riprap conduit and prevent the conduit from tilting and affecting the position of the riprap, the support assembly 5 in this embodiment includes a first motor 501, which is fixed to the inner bottom wall of the mounting plate 4, and a connecting plate 502 is fixed to the upper surface of the mounting plate 4. The output shaft of the first motor 501 passes through and extends to the inside of the connecting plate 502, and a gear 503 is fixed thereto. The output shaft of the first motor 501 drives the gear 503 to rotate. Two racks 504 are meshed on the outer side of the gear 503 and are symmetrically distributed with respect to the central axis of the gear 503. The gear 503 drives the racks 504 on both sides to move, so that the racks on both sides 504 moves in the opposite direction, a first support plate 505 is fixed to the back of the rear rack 504, the rear rack 504 drives the first support plate 505 to move, the right side of the first support plate 505 passes through and extends to the right side of the connecting plate 502, and is fixed to the outer side of the catheter body 2, the first support plate 505 drives the catheter body 2 to move so as to adjust the stone throwing position, and a second support plate 506 is fixed to the front of the front rack 504, the front rack 504 drives the second support plate 506 to move so as to adjust the counterweight position, so that the catheter body 2 keeps balanced and stable during the stone throwing process, and a counterweight assembly is arranged on the second support plate 506.

[0026] In this example, two sliding rods are fixed between the left and right inner walls of the connecting plate 502, and are symmetrically distributed front to back with the central axis of the connecting plate 502. The outer sides of the two sliding rods are respectively slidably connected to the inner sides of the two racks 504, so as to limit the moving trajectory and angle of the racks 504 and prevent the racks 504 from derailing from the gear 503.

[0027] It should be noted that the counterweight assembly includes a second motor 507, which is fixed to the right side of the second support plate 506. The output shaft of the second motor 507 passes through and extends to the inside of the second support plate 506, and is fixed with a threaded rod 508. The output shaft of the second motor 507 drives the threaded rod 508 to rotate. The outer side of the threaded rod 508 is threadedly connected with a threaded block 509, and the threaded rod 508 drives the threaded block 509 to move. The lower surface of the threaded block 509 passes through and extends to the lower side of the second support plate 506, and is fixed with a counterweight 510. The threaded block 509 drives the counterweight 510 to move, so that the position of the counterweight 510 can be adjusted to adjust the unilateral torque and restore the device to a balanced state. A sliding opening is provided on the lower surface of the second support plate 506, and the threaded block 509 is located inside the sliding opening, and the width of the sliding opening is adapted to the width of the threaded block 509. The sliding opening limits the angle of the threaded block 509 to prevent the angle of the threaded block 509 from shifting when it moves.

[0028] See also Figure 4-5 In order to avoid derailment when the device is unbalanced, the moving assembly 7 in this embodiment includes a fixing rod 701, one end of which is fixed to the lower surface of the mounting plate 4, and the number of fixing rods 701 is two, and the positions correspond to the positions of the two track grooves 6. The other end of the fixing rod 701 penetrates and extends into the inside of the track groove 6, and is fixed with a fixing plate 702. The lower surface of the fixing plate 702 is fixed with a first pulley 703, and the left and right sides of the fixing plate 702 are fixed with second pulleys 704. The distance between the two opposite sides of the second pulleys 704 is adapted to the width of the track groove 6, so that the device can move smoothly during movement. During the process, the position will not be offset, and the stability during movement is maintained. Baffles 705 are fixed to the inner walls of the left and right sides of the track groove 6, and a mounting groove 706 is opened on the upper surface of the fixed plate 702. A spring 707 is fixed to the inner bottom wall of the mounting groove 706, and a third pulley 708 is fixed to the other end of the spring 707. When the weight on both sides of the device is unbalanced, the mounting plate 4 will tilt to one side, and the first pulley 703 on the tilted side will detach from the inner bottom wall of the track groove 6, and the second pulley 704 will move up.

The number of mounting grooves 706 is equal to the number of baffles 705 , and their positions correspond one to one to ensure the stability of the pulley inside the track groove 6 .

[0030] The working principle of the above embodiment is:

[0031] (1) Due to the different positions of the riprap, the position of the catheter body 2 needs to be adjusted, and the first motor 501 is turned on. The output shaft of the first motor 501 drives the gear 503 to rotate, and the gear 503 drives the racks 504 on both sides to move, so that the racks 504 on both sides move in opposite directions. The rear rack 504 drives the first support plate 505 to move, and the first support plate 505 drives the catheter body 2 to move, so as to adjust the riprap position. At the same time, the front rack 504 drives the second support plate 506 to move, and the second support plate 506 drives the counterweight 510 to move, so that the catheter body 2 can keep balanced and stable during the riprap process.

[0032] (2) When a large number of stones are put into the feed hopper 3, the weight on both sides of the device is unbalanced, causing the mounting plate 4 to tilt to one side. The first pulley 703 on the tilted side detaches from the inner bottom wall of the track groove 6, and the second pulley 704 moves up. At this time, the third pulley 708 is squeezed between the baffle 705 to compress the spring 707, thereby avoiding derailment during the movement. Then the second motor 507 is turned on, and the output shaft of the second motor 507 drives the threaded rod 508 to rotate, and the threaded rod 508 drives the threaded block 509 to move, and the threaded block 509 drives the counterweight block 510 to move, so that the position of the counterweight block 510 can be adjusted to adjust the unilateral torque and restore the device to a balanced state.
