[0020] The reference numerals in the accompanying drawings include: 1. Guide plate 2. Buffer plate 3. Feed hose 4. Crusher 5. Collar 6. Cylinder 7. Feed hopper 8. Belt.

[0021] In the following statements, directional terms such as "left," "right," "up," and "down" are based on the directions shown in the diagram. In practice, if the corresponding structures are changed in the same direction based on the direction while maintaining their relative positions, it will not affect the implementation of the plan.

[0022] Example: A material conveying device, such as Figure 1 As shown, it includes a feeding hopper 7, a feeding hose 3 is fixedly provided in the feeding hopper 7, and a buffer plate group is symmetrically fixedly provided in the feeding hopper 7 along its axis. Each buffer plate group includes a buffer elastic plate 2 and a flow guide plate 1 arranged sequentially from top to bottom. Both the buffer elastic plate 2 and the flow guide plate 1 are rubber plates, and the buffer elastic plate 2 extends to directly above the flow guide plate 1.

[0023] like Figure 3 As shown, a cylinder 6 is fixedly installed in the hopper 7. A collar 5 is fixedly connected to the movable end of the cylinder 6. The collar 5 and the feed hose 3 are fixedly connected. The feed hose 3 includes a feed end and a discharge end. The feed end is fixedly connected to and communicates with the discharge port of the crusher 4. After the cylinder 6 pushes the feed hose 3 to bend, the discharge end alternately moves to the top of the buffer elastic plates 2 on both sides. The feed hose 3 is a corrugated pipe.

[0024] like Figure 2 As shown, this scheme has two sets of buffer plates, which are symmetrically arranged along the axis of the feed hopper 7. The feed end of the feed hose 3 is connected to the discharge port of the crusher 4. The cylinder 6 pushes the collar 5 to move. The collar 5 drives the discharge end of the feed hose 3 to alternately move to the top of the buffer elastic plate 2 of one of the buffer plates, so that the other set of buffer plates is not used and is temporarily stationary. The material flows to the buffer plate set through the discharge end of the feed pipe. After being buffered by the buffer elastic plate 2, the impact force of the material is reduced. Then, the material falls from the buffer elastic plate 2 to the guide plate 1, where the impact force is reduced again. After being buffered twice, the material falls onto the belt 8 to achieve a natural buffering effect.

[0025] This solution uses two sets of buffer plates and a feed hose 3 that can change the discharge direction to enable the two sets of buffer plates to be used alternately, thereby effectively buffering the stress generated by impact and extending the service life of the buffer plates.
