[0028] Support frames 116 are arranged on the ground on the same side of the feeding port 112 and on both sides of the bottom casing 111, a load bearing seat 411 with a side U-shaped structure is arranged on the two support frames 116 in a common lifting manner, a material containing frame 412 for collecting the guided material is slidably arranged in the load bearing seat 411, the sliding of the material containing frame 412 is controlled by the extension and retraction of an electric cylinder 7, when the material containing frame 412 slides to the bottom of the lower guide plate 212 to receive the material or moves away from the lower guide plate 212, the opening and closing assembly 3 is automatically triggered to open or close.

[0029] A through port 115 is arranged on the feeding port 112, a discharge port 413 for feeding material into the through port 115 is arranged on the material containing frame 412, and an electric gate valve is arranged on the discharge port 413.

[0030] Through the above structure, in the initial state, the load bearing seat 411 is lowered to the lowest position, the material containing frame 412 is slid to the bottom of the lower guide plate 212, at this time, the opening and closing assembly 3 is triggered to open, in the process of continuously feeding sand and stone from the feeding port 112, when the sand and stone falls to the bottom wall of the bottom casing 111, it will slide downward along the upper guide plate 211 under the action of its own weight, then it will slide from the discharge port 213 to the lower guide plate 212, and then it will slide from the lower guide plate 212 to the material containing frame 412, thus avoiding the increase and heightening phenomenon caused by the accumulation of sand and stone on the bottom wall of the bottom casing 111.

[0031] When the sand and gravel in the holding frame 412 reaches a certain capacity, the holding frame 412 is first controlled to move away from the lower guide plate 212. At this time, the contact with the opening and closing component 3 will be released and the closing operation will be performed. Then, the bearing seat 411 is controlled to rise and be positioned above the through port 115. Next, the holding frame 412 is controlled to slide to the through port 115 and the discharge port 413 is aligned with the through port 115. Finally, the electric gate valve is controlled to be in the open state, so that the sand and gravel in the holding frame 412 fall into the through port 115 and the filling operation is repeated, thereby improving the efficiency of the device.

[0032] Combined with appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, the opening and closing assembly 3 includes fixed seats 311 symmetrically arranged at both ends of the lower guide plate 212. A rotating shaft 312 passes through both fixed seats 311, and an opening and closing plate 313 is mounted on this rotating shaft 312. A gear 314 is mounted on the rotating shaft 312. A toothed plate 315 with a spring-loaded function and meshing with the gear 314 is slidably mounted on the fixed seat 311. A groove is formed along the length of the fixed seat 311, and a sliding rod is fixedly mounted within this groove. A slider fixedly connected to the toothed plate 315 slides on the sliding rod, and the sliding rod also has… A return spring is fitted in place. When the opening and closing plate 313 is closed, the spring force of this return spring can withstand the impact force of sand and gravel on the lower guide plate 212. A moving rod 316 is fixedly provided on the toothed plate 315 and slides with the lower guide plate 212. The moving rod 316 extends to the bottom of the lower guide plate 212.
