As shown in Figure 1, a system and method for rapid transportation of sand and gravel materials proposed by the present invention include:

The conveying mechanism 1 is set at the place of use, and one end is adjacent to the place where the materials are stacked; in the present invention, the conveying mechanism 1 is preferably a conveyor belt, and the material (sand and gravel) can be placed on the conveyor belt by operators or operating equipment, etc. Conveyor belt for material transportation;

The material buffer area 2 is communicated with the outside through the conveying channel 3; and the conveying channel 3 includes a feeding port and a discharging port 32, and the feeding port is arranged adjacent to the other end of the conveying mechanism 1; when the conveying mechanism 1 transmits the material After reaching the end of the conveying mechanism 1, under the action of the material's own gravity, the material enters the conveying channel 3; and with its own gravity, it passes through the bore and falls to the material buffer area 2. In the present invention, the conveying channel 3 is the conveying channel 3. It can also be a channel opened by the feeding channel 3 for the drilling equipment; the specific situation is determined according to the actual situation, and the present invention will no longer limit this;

As shown in Figure 1, when the material passes through the feeding channel 3 and reaches the material buffer area 2, since there is a platform in the material buffer area 2 for temporary storage after falling from the feeding channel 3, the material passing through the feeding channel 3 The material may fall on the platform where the material is temporarily stored. Due to the continuous falling of the material, the material on the platform gradually increases. When the material on the platform reaches a certain amount, because the platform and the unloader 42 are set close to each other, when the platform When the bearing range of the output platform is long, the excess material will flow into the discharge machine 42; and, in the present invention, preferably, the shaft center of the discharge port 32 is close to the discharge port 32 from the material storage mechanism 4. The distance between the edges is 1.5m; this allows the platform to form a certain space for temporary storage of materials; and when it exceeds the bearing range of the space, the materials will enter the storage mechanism 4;

In this environment, the natural accumulation of materials and the impact creep can be fully utilized; that is, when the materials fall to the material buffer zone 2 after passing through the feeding channel 3, the impact force of the falling materials can be buffered due to the setting of the platform , and due to the gradual increase of materials, the materials falling into the unloading machine 42 can enter the unloading machine 42 at a lower speed than the falling speed, and because the materials on the platform gradually increase, the existing materials on the platform can also be used.
