A winch is provided on one side of the support frame 3, and one end of the steel cable of the winch is fixedly connected to one side of the bottom end of the inner chute 5. When the winch is started to unwind the steel cable, the inner chute 5 gradually slides out from the inner side of the outer chute 4 to extend the length of the chute. Conversely, the inner chute 5 slides into the inner side of the outer chute 4 to reduce the length of the chute, so that the length of the chute can guide the stone to the required position, and at the same time, it is convenient to store and carry the chute. At the same time, the bottom of the inner chute 5 can be provided with lighting and video, which is convenient for underwater workers to construct and for onboard inspection personnel to inspect.
[0019] The opening and closing component is used to close the port of the chute when the chute deviates to prevent the loss of stone. The opening and closing component is connected to the inner chute 5. The opening and closing component includes a threaded shaft 6 that is rotatably connected to the inside of the inner chute 5. The outer side of the threaded shaft 6 is threadedly connected to a transmission frame 7. The surface of the threaded shaft 6 is provided with two spiral grooves with opposite rotation directions. The two transmission frames 7 are respectively connected to the two spiral grooves, so that when the threaded shaft 6 rotates, the two transmission frames 7 can approach or move away from each other. The transmission frame 7 is slidably connected to the inside of the inner chute 5. One end of the transmission frame 7 is fixedly connected to a material door 8. The material door 8 is slidably connected to the inside of the inner chute 5. Both sides of the inner chute 5 They are all fixedly connected with a fixing frame 9, and the threaded shaft 6 is rotatably sleeved inside the fixing frame 9. The threaded shaft 6 is limited and supported by the fixing frame 9 so that the threaded shaft 6 is kept inside the fixing frames 9 on both sides. A coil spring is provided between the threaded shaft 6 and the fixing frame 9, and the two ends of the coil spring are respectively connected to the threaded shaft 6 and the fixing frame 9.

The bottom of the pull handle 19 is threadedly connected to a fixing nail 20, and the outer side of the fixing nail 20 is threadedly connected to a bottom plate 21.
[0020] It needs to be explained that, by setting the setting gate 8, when throwing the stone, the outer chute 4 and the inner chute 5 are adjusted to the material falling position, and the underwater worker pulls the pull handle 19 to gradually drive the rope 10 to rotate the threaded shaft 6, the rotation of the threaded shaft 6 gradually unwinds the rope 10, thereby extending the movable range of the pull handle 19, the coil spring between the threaded shaft 6 and the fixed frame 9 is retracted when the threaded shaft 6 rotates, the transmission frame 7 on both sides slides laterally outside the threaded shaft 6 and moves away from each other, the transmission frame 7 simultaneously drives the two sides The material door 8 slides out of the inside of the inner chute 5, so that the bottom port of the inner chute 5 is open, at this time the stone is dropped from the top port of the outer chute 4, and falls in a specific position under the guidance of the outer chute 4 and the inner chute 5, by manually pulling the pull handle 19 by the worker, when the ship shakes and causes the position of the inner chute 5 to deviate, the worker loosens the pull handle 19 to stretch the coil spring between the threaded shaft 6 and the fixed frame 9, and drives the threaded shaft 6 to rotate to make the transmission frame 7 on both sides approach each other, and drive the material door 8 on both sides to slide to the inside of the inner chute 5 to close the port at the bottom end of the inner chute 5, so that the stone stops flowing out, so as to avoid waste caused by stone loss, at the same time, by connecting the fixed nail 20 with the pull handle 19, inserting the fixed nail 20 into the seabed or the inside of the stone and laying the counterweight stone on the surface of the bottom plate 21 to enhance the stability of the fixed nail 20, when the inner chute 5 deviates seriously, pull out the fixed nail 20, at the same time, the material door 8 can be displaced into the inside of the inner chute 5 to close the port of the inner chute 5, so that the inner chute 5 can be closed without the pull handle 19 being pulled by the underwater worker when the inner chute 5 deviates.
[0021] As shown in Figures 4-10 , the outer side of the threaded shaft 6 is fixedly connected with an outer convex ring 11, the inside of the inner chute 5 is rotatably connected with a connecting plate 12, the connecting plate 12 is rotatably sleeved on the outer side of the threaded shaft 6, the top of the connecting plate 12 is fixedly connected with a counterweight 13, the overall weight of the counterweight 13 is much larger than that of the connecting plate 12, one side of the connecting plate 12 is fixedly connected with an inner convex ring 22, the outer convex ring 11 is slidingly connected on the inner side of the inner convex ring 22, the inner wall of the inner chute 5 is slidingly connected with a cam 14, the cam 14 is fixedly connected on one side of the connecting plate 12, the inside of the inner chute 5 is slidingly connected with an L-shaped frame 15, the top of the L-shaped frame 15 is fixedly connected with a vertical plate 16, the vertical plate 16 is slidingly connected in the inside of the inner chute 5, the inner wall of the inner chute 5 is rotatably connected with an extension plate 17, one side of the vertical plate 16 is rotatably connected with a support plate 18, the support plate 18 and the extension plate 17 are hingedly connected, the extension plate 17 and the support plate 18 are arranged in multiple, and the multiple extension plates 17 are linearly arrayed on the inner wall of the inner chute 5.
[0022] It should be noted that, by providing the extension plate 17, when the threaded shaft 6 rotates to slide the material door 8 to open the bottom port of the inner chute 5, the threaded shaft 6 simultaneously drives the outer convex ring 11 to rotate. When the outer convex ring 11 is about to rotate one circle, it will contact the inner convex ring 22. At this time, the rotation of the threaded shaft 6 will drive the inner convex ring 22 to rotate under the action of the outer convex ring 11, thereby causing the connecting plate 12 to rotate clockwise. When the connecting plate 12 rotates to a vertical state, that is, Figure 4 In the state shown, the cam 14 will rotate at the same time and gradually lose contact with the L-shaped frame 15. The L-shaped frame 15 and the vertical plate 16 will descend under the influence of their own weight, so that the extension plate 17 and the support plate 18 tend to be vertical and fit against the inner wall of the inner chute 5. At this time, the stones falling in the inner chute 5 will not be blocked by the extension plate 17; when the inner chute 5 deviates from the drop point, the threaded shaft 6 rotates and resets under the action of the coil spring, so that the material door 8 slides toward the inside of the inner chute 5 to close the port at the bottom of the inner chute 5, and the outer convex ring 11 simultaneously The counterweight 13 loses contact with the inner convex ring 22. At this time, under the influence of its own weight and gravity, the counterweight 13 moves downward, thereby driving the connecting plate 12 to rotate counterclockwise. At the same time, the cam 14 gradually contacts the L-shaped frame 15, and causes the L-shaped frame 15 and the vertical plate 16 to slide upward, thereby causing the support plate 18 to flip and support the extension plate 17, so that the extension plate 17 is tilted and the bottom is close to the center of the inner chute 5. At this time, the falling stones in the inner chute 5 will contact the extension plate 17, and the inner wall of the inner chute 5 is provided with multiple extension plates 17. The descending speed of the stone is gradually slowed down by multiple extension plates 17, so as to prevent the still falling stone from contacting the material door 8 sliding into the inner chute 5 and causing damage. At the same time, multiple extension plates 17 will reduce the space at their location, and the stone will accumulate at this location when it descends. When the material door 8 is opened, the extension plates 17 will shrink and restore the space at their location, and the stone can continue to descend. In this way, when the material door 8 is closed, the rapidly falling stone will not accumulate and be gradually compacted in the inner chute 5, resulting in the inner chute 5 becoming Small stone is stuck inside the inner chute 5 and cannot fall down, that is, when the bottom port of the inner chute 5 is open, the extension plate 17 shrinks and fits the inner wall of the inner chute 5, and when the material door 8 enters the inner chute 5 to close the bottom port of the inner chute 5, the extension plate 17 stretches to slow down the falling speed of the stone to avoid damage to the material door 8 caused by impact, and at the same time reduces the space where the extension plate 17 is located, so that when the bottom port of the inner chute 5 is open, the stone can continue to fall through the space vacated after the extension plate 17 flips over and fits the inner wall of the inner chute 5 to avoid blockage.
[0023] Working principle: when the stone is thrown, the outer chute 4 and the inner chute 5 are adjusted to the material falling position, and the rope 10 gradually drives the threaded shaft 6 to rotate by pulling the pull handle 19 by the underwater worker, the coil spring between the threaded shaft 6 and the fixed frame 9 is contracted when the threaded shaft 6 rotates, the transmission frame 7 on the outside of the threaded shaft 6 slides horizontally and moves away from each other, the transmission frame 7 simultaneously drives the material door 8 on both sides to slide out of the inside of the inner chute 5, so that the bottom port of the inner chute 5 is opened, at this time the stone is dropped from the top port of the outer chute 4, and falls to a specific position under the guidance of the outer chute 4 and the inner chute 5, by manually pulling the pull handle 19 by the worker, when the position of the inner chute 5 deviates due to the sway of the ship, the worker releases the pull handle 19, the coil spring between the threaded shaft 6 and the fixed frame 9 is stretched, and the threaded shaft 6 is driven to rotate to make the transmission frame 7 on both sides approach each other, and drive the material door 8 on both sides to slide to the inside of the inner chute 5 to close the port at the bottom end of the inner chute 5, so that the stone stops flowing out, so as to avoid waste caused by stone loss; when the material door 8 slides to the inside of the inner chute 5 to close the port at the bottom of the inner chute 5, the outer convex ring 11 loses contact with the inner convex ring 22 at the same time, at this time, under the influence of the weight of the counterweight 13 and gravity, the counterweight 13 moves downward, thereby driving the connecting plate 12 to rotate counterclockwise, at the same time, the cam 14 gradually contacts the L-shaped frame 15, and the L-shaped frame 15 and the vertical plate 16 slide upward, thereby making the support plate 18 flip to support the extension plate 17, so that the extension plate 17 is inclined and the bottom is close to the center position of the inner chute 5, at this time, the stone falling in the inner chute 5 will contact the extension plate 17, and the inner wall of the inner chute 5 is provided with a plurality of extension plates 17, which gradually slow down the falling speed of the stone, thereby avoiding the contact between the still falling stone and the material door 8 sliding into the inner chute 5 to cause impact and damage, and avoiding the phenomenon of stone accumulation and compaction.
