[0018] Figure 2 This is a schematic diagram of the loading box of this utility model;
[0019] Figure 3 This is a schematic diagram of the structure of this utility model from the right side; Detailed Implementation
[0020] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution: a slope protection sand and gravel cushion layer conveying device, including an inclined support side plate 1, a support frame 2 fixedly connected to both ends of the support side plate 1, a movable base 3 fixedly connected to the support frame 2, a loading box 4 slidably connected to the support side plate 1, and a power component for driving the loading box 4 to slide on the support side plate 1. Two sets of support side plates 1 are provided and symmetrically arranged on both sides of the loading box 4. The two sets of support side plates are reinforced by transverse connecting rods. A discharge port 41 is opened at the lower end of the box wall of the loading box 4. A discharge gate 42 for blocking the discharge port 41 is provided on the discharge port 41. The discharge gate 42 is slidably connected to the box wall of the loading box 4. A linear drive component for driving the discharge gate 42 to slide is fixedly connected to the outer wall of the loading box 4.
[0021] The upper and lower ends of the support side plate 1 are fixedly connected to the support frame 2. The bottom end of the support frame 2 is fixedly connected to the movable base 3. The movable base 3 includes a base plate 31 fixedly connected to the bottom end of the support frame 2 and a moving wheel 32 rotatably connected to the base plate 31. Multiple sets of moving wheels 32 are provided and are equally spaced on the base plate 31.
[0022] Slider 71 is fixedly connected to the outer walls on the left and right sides of the loading box 4, and slide rails 72 matching slider 71 are opened on the support side plate 1.
[0023] The power assembly includes a rope 51 with its free end fixedly connected to the loading box 4, and a winch 52 fixedly connected to the tail end of the rope 51. The winch 52 is fixedly connected to a movable base 3 located at the upper end of the support side plate 1. The rope 51 passes through a first pulley 53, which is fixedly connected to a support frame 2 located at the upper end of the support side plate 1 to guide the rope 51.
[0024] The discharge port 41 is elongated, and its length direction is the same as that of the loading box 4. The loading box 4 is a cuboid box, and the discharge port 41 is rectangular, with its length direction along the long side of the loading box 4. When the loading box 4 slides at a constant speed along the supporting side plate 1, the sand and gravel inside the loading box are discharged from the discharge port 41, and the sand and gravel are spread relatively evenly on the slope.
[0025] The bottom of loading box 4 is tilted.
[0026] The end of the unloading gate 42 is slidably connected to a matching guide rail groove 49, which is fixedly connected to the outer wall of the loading box 4. In order to ensure that the unloading gate can slide smoothly along the height of the loading box 4, both the left and right ends of the unloading gate are slidably connected to the guide rail groove 49 with an L-shaped cross-section.
[0027] The linear drive assembly includes an electric push rod 61 whose output end is fixedly connected to the unloading gate 42, and a mobile power supply 62 electrically connected to the electric push rod 61. Both the electric push rod 61 and the mobile power supply 62 are fixedly connected to the wall of the loading box 4. When the electric push rod 61 retracts, the unloading gate 42 slides upward. At this time, the unloading gate 42 will not block the unloading port 41, and the sand and gravel will be laid from the unloading port 41 onto the slope. When the electric push rod 61 extends, the unloading gate 42 slides downward. At this time, the unloading gate 42 will block the unloading port 41.
[0028] Working principle: The device is set up on the slope to be constructed. Then, the worker loads sand and gravel into the loading box 4. Next, the worker starts the winch 52, and the rope 51 is wound up by the winch 52. The loading box 4 will slowly move upward along the supporting side plate 1. The worker starts the electric push rod 61, which retracts and the unloading gate 42 slides upward. At this time, the unloading gate 42 will not block the unloading port 41, and the sand and gravel will be laid on the slope from the unloading port 41. When the loading box 4 moves from the lowest point to the highest point of the slope, the electric push rod 61 is operated. The electric push rod 61 extends and the unloading gate 42 slides downward. At this time, the unloading gate 42 will block the unloading port 41. Next, the worker moves the device in the lateral direction of the slope and pushes the supporting frame 2 at both ends of the supporting side plate 1. The device moves laterally and continues to lay the slope.
