Example 1

When long-arm mining is adopted, the coal falls directly to the ground or falls onto the conveyor belt for transportation. If it falls directly to the ground, workers are required to collect and transfer it to the conveyor belt. If it falls directly onto the belt, accidents such as belt damage will be caused. Based on this, the inventor proposes a push-type belt conveyor for coal mining, as shown in Figures 1-4, which includes a hopper 1 and a suspended conveyor body 2 installed on one side of the hopper. The hopper 1 is provided with a cavity for accommodating the fallen coal raw materials. The hopper 1 is close to the side wall of the suspended conveyor body 2 to form a discharge port 3. At least one set of feeding components is arranged in the cavity, and the suspended conveyor body 2 on one side of the hopper 1 is pushed toward the discharge port 3. The conveyor body 2 feeds the material, and at least one feeding cavity 14 with a semicircular bottom is formed in the receiving hopper 1. The feeding component rotates in the feeding cavity 14. The feeding component includes a rotating shaft 15 and a spiral blade 16 installed on the rotating shaft 15. The rotating shaft 15 is rotatably installed between the two ends of the feeding cavity 14. The rotating shaft 15 is connected to the chain 12 driving component, and the chain 12 driving component provides a rotational driving force to the rotating shaft 15, carrying the spiral blade 16 to rotate in the feeding cavity 14. The spiral blade 16 is configured to, when rotating, deliver the coal raw material in the feeding cavity 14 to the discharge port 3 for discharge.

It should be noted that the discharge port 3 is separated by the feeding cavity 14, and the formed outlet corresponds to the feeding cavity 14 one by one. When the corresponding discharge operation is performed, the coal raw materials are discharged from each outlet of the feeding port.

Example 2

On the basis of Example 1, the chain 12 drive assembly is provided with a tensioning adjustment device. When the conveying operation is carried out, the coal raw material falls into the receiving hopper 1 and generates vibration. The chain 12 of the chain 12 drive assembly and the gear 11 are easy to fall off, affecting the feeding. Therefore, the tensioning adjustment device is designed to make the chain 12 and the gear 11 of the chain 12 drive assembly tensioned and prevent them from falling off.

It should be noted that relatively distributed support legs 4 are respectively provided on both sides of the bottom of the receiving hopper 1 , the tensioning adjustment device and the suspended conveyor body 2 are respectively provided on two groups of support legs 4 , and the support legs 4 perform corresponding supporting operations on the receiving hopper 1 .

The gear 11 and the rotating shaft 15 are provided with a plurality of corresponding ones. The side wall of the sliding groove 7 is provided with a strip groove 13. The tensioning wheel 10 is rotatably connected to the sliding plate 5 through a rotating shaft that movably passes through the strip groove 13. The tensioning wheel 10 corresponding to the driving motor 9 is fixedly connected to the conveying end of the driving motor 9. The chain 12 is sequentially wound around the tensioning wheel 10 and the gear 11. When the sliding plate 5 moves up and down, the distance between the tensioning wheel 10 and the gear 11 is adjusted to tension the chain 12.

When in use, the device is installed at a suitable location for coal mining. The receiving hopper 1 is used to receive materials during mining. It can be installed on a mobile track or mobile equipment and move with the mining direction to collect materials.

Start the drive motor 9 of the chain 12 drive assembly, and provide a rotational driving force to the rotating shaft 15 through the chain 12 transmission, so that the coal raw materials are pushed to the discharge port 3 and fall onto the side hanging belt conveyor body.
