[0032] A feeding hopper 11 is provided at the output end of the belt conveyor 10, a side door 12 is opened on one side of the upper end of the feeding hopper 11, a feeding hole 14 is provided at the lower end of the feeding hole 14, a buffer bin 16 is provided at the bottom of the feeding hole 14, a flap 17 is provided at the bottom of the buffer bin 16, and an underground material transport vehicle 19 is provided at the output end of the buffer bin 16, and the underground material transport vehicle 19 transports the materials to the target position underground.

[0033] The discharge bin 4 is conical, a grille 3 is provided on the top of the discharge bin 4, anti-sticking plates 5 are provided on the inner walls on both sides of the bottom of the discharge bin 4, and an anti-blocking bracket 6 is provided in the middle of the bottom side of the discharge bin 4;

[0034] The materials are fed to the material transport vehicle 2 through the raw material warehouse 1, and the material transport vehicle 2 transports the materials to the unloading warehouse 4 for unloading;

[0035] The top grille 3 of the unloading bin 4 simply breaks up the materials to prevent them from agglomerating. The anti-sticking plate 5 at the conical bottom of the unloading bin can prevent the materials from sticking to the bottom of the unloading bin 4. The anti-blocking bracket 6 relieves the materials from being empty at the bottom of the bin.

[0036] The material at the bottom of the discharge bin 4 is evenly fed to the belt conveyor 10 through the disc feeder 7. The belt conveyor 10 transports the material to the side door 12 for unloading, and the material is unloaded downward through the feeding hole 14; the inner wall of the feeding hole 14 is inlaid with an anti-sticking material layer 15 to prevent the material from sticking to the wall and causing clogging of the feeding hole;

[0037] After the materials are unloaded into the buffer bin 16, they are unloaded through the flap 17. The flap controller 18 controls the flap 17 to open and unload the materials to the underground material transport vehicle 19. The underground material transport vehicle 19 transports the materials to the target location underground.

[0038] The inner wall of the feeding hole 14 is inlaid with an anti-sticking material layer 15, and one side of the feeding hole 14 is connected to an air duct 9, and the input end of the air duct 9 is connected to a fan 8. The fan 8 and the air duct 9 are used to blow air into the feeding hole 14 to prevent the inner wall from being damp and causing poor material feeding.

[0039] The input end of the flap 17 is connected to a flap controller 18 ; the input end of the side door 12 is provided with a side door controller 13 .

[0040] The side door controller 13, flap controller 18, fan 8, valve of air duct 9, disc feeder 7, and belt conveyor 10 are all controlled by the automatic control system, and remote control is performed through the automatic control system to improve work efficiency;

[0041] A method for conveying dry concrete material underground, comprising the following steps:

[0042] The automatic control system is used to sequentially open the flap 17 of the downhole buffer bin 16, close the side door 12, open the valve of the air duct 9, and start the fan 8 for ventilation for 20-30 minutes, and then the fan 8 and the valve of the air duct 9 are sequentially closed, the side door 12 is opened, and the flap 17 is closed to dry the water vapor in the feeding hole 14 and the buffer bin 16 to avoid the inner wall of the feeding hole 14 being damp and causing poor feeding;

[0043] The belt conveyor 10 and the disc feeder 7 are started in sequence by the automatic control system, and the dry concrete material is poured from the material transport vehicle 2 into the discharge bin 4. The rotation speed of the disc feeder 7 is adjusted so that the dry concrete material can be evenly fed to the belt conveyor 10. The belt conveyor 10 transports the dry concrete material to the side door 12 for feeding, and the dry concrete material is discharged downward through the feeding hole 14 into the underground buffer bin 16;

[0044] After the alignment of the bottom of the buffer bin is completed, the underground material transport vehicle 19 opens the flap 17 by adjusting the flap control lever 18 through the automatic control system. After the underground material transport vehicle 19 is filled with dry concrete, the flap 17 is automatically closed and the loading work of the next vehicle is carried out. The underground material transport vehicle 19 transports the dry concrete to the target position underground, and the overall balance of the dry concrete is uniformly organized and controlled by the automatic control system.

[0045] Before the end of a single transportation of dry concrete, all materials in the unloading bin 4, the disc feeder 7, the belt conveyor 10, the feeding hopper 11, the feeding hole 14, the anti-sticking material layer 15, and the buffer bin 16 should be emptied to prevent blockage after the dry concrete is hardened;

[0046] The belt conveyor 10 and the disc feeder 7 are closed in sequence through the automatic control system, and the side door 12, the flap 17, the air duct 9 valve, and the fan 8 are opened and closed in sequence through the automatic control system again. Ventilation is carried out for 10-20 minutes. When the automatic control system confirms that there is no accumulation of material in the feeding hole 14 and the buffer bin 16, the fan 8, the air duct 9 valve and the flap 17 are closed in sequence.

[0047] In order to prevent local fine scale from forming on the inner wall of the feeding hole, which will gradually affect the smoothness of the feeding, stone slag (gravel, sand) is fed alternately at regular intervals after the feeding of dry concrete is completed. This not only meets the needs of underground operations for various materials, but also solves the problem of scale removal and dredging, saves energy and improves efficiency, and reduces the safety risks of using other modes of transportation.

[0048] The present invention achieves the purpose of transporting materials from the surface to underground by combining short-distance automobile transportation, belt conveyor and feeding hole 14. Compared with the ramp transportation process used in the prior art, the present invention eliminates the ramp transportation process and uses the height difference of materials to achieve self-sliding, thereby improving transportation efficiency, reducing energy consumption, and effectively reducing the risk of accidents, which is beneficial to on-site management and has high reliability.
