[0020] 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.
[0021] Please see Figures 1 to 4This utility model provides a technical solution: a high-efficiency stone-throwing auxiliary device, including a hull 1 and a guide rail 3 fixedly connected to the hull 1 by a counterweight 2. The counterweight 2 is placed on the upper end of the guide rail 3, pressing the guide rail 3 onto the hull 1 for fixation. Two guide rails 3 are arranged in parallel, and two sliding components 4 are slidably connected to each guide rail 3. A stone-throwing box 7 is arranged between the four sliding components 4. The stone-throwing box 7 has an opening at the top and a bottom plate opening and closing component 8 at the bottom. Through the cooperation of the guide rails 3 and the sliding components 4, the stone-throwing box 7 can be easily adjusted laterally to adjust the stone-throwing position, thereby improving the stone-throwing efficiency.
[0022] The sliding assembly 4 includes a U-shaped frame 401 that is snapped onto the lower end of the guide rail 3. Pulleys 402 are symmetrically rotatably connected to the inner surface of the U-shaped frame 401. The guide rail 3 is an I-beam. The two pulleys 402 are located on opposite sides of the web of the guide rail 3 and are slidably connected to the lower flange of the guide rail 3. The sliding assembly 4 can slide freely on the guide rail 3.
[0023] The bottom plate opening and closing assembly 8 includes a support plate 806 fixedly connected to both sides of the bottom end of the stone-throwing box 7. A bidirectional lead screw 802 is rotatably connected to the bottom of one support plate 806, and a slide rod 803 is installed at the bottom of the other support plate 806. The bidirectional lead screw 802 and the slide rod 803 are arranged in parallel. A movable block 804 is symmetrically threaded at the positive and negative threads of the bidirectional lead screw 802. A slider 805 is symmetrically slidably connected to the slide rod 803. The positions of the movable block 804 and the slider 805 correspond to each other. A bottom plate 807 is provided between the corresponding movable block 804 and slider 805. The two bottom plates 807 can cover the bottom opening of the stone-throwing box 7. A rotating motor 801 is installed at one end of the bidirectional lead screw 802. Using an excavator, stones are placed into the stone-throwing box 7. By controlling the rotating motor 801 to move the two bottom plates 807 of the stone-throwing box 7 away from each other, a large number of stones can be thrown down as a whole, avoiding the problem of water flow affecting the throwing of individual stones.
[0024] A drive motor 6 is mounted on the side of the U-shaped frame 401. The output end of the drive motor 6 passes through the U-shaped frame 401 and is connected to the pulley 402. The drive motor 6 can drive the pulley 402 to rotate, thereby driving the U-shaped frame 401 to move on the guide rail 3, which facilitates the adjustment of the stone-throwing position of the stone-throwing box 7.
[0025] An overlapping block 5 is fixedly connected to the inner side of the U-shaped frame 401. The stone-throwing box 7 is placed on the overlapping block 5 and fixedly connected by bolts. The stone-throwing box 7 overlaps on the U-shaped frame 401. By adjusting the distance between the two sliding components 4 on the same guide rail 3, stone-throwing boxes 7 of different sizes can be adapted, increasing the applicability of this device.
[0026] Working principle: The workers first use an excavator to put stones into the stone throwing box 7. Then, the drive motor 6 is started to drive the pulley 402 to rotate, which in turn drives the U-shaped frame 401 to move on the guide rail 3, so as to adjust the throwing position of the stone throwing box 7. After the stone throwing box 7 is moved to the appropriate position, the rotating motor 801 is started to make the two bottom plates 807 at the bottom of the stone throwing box 7 move away from each other, so that a large number of stones can be thrown down as a whole, avoiding the problem of water flow affecting the throwing of individual stones.
