[0032] See also Figures 1-8 In an embodiment of the present invention, a gold mine mining using a dust suction drilling structure comprises:

[0033] A frame 1, with a bucket 2 fixed at one end of the frame 1;

[0034] A drill bit 14 is arranged on the frame 1, and an angle adjustment assembly for adjusting the angle of the drill bit 14 is provided on the frame 1. The angle adjustment assembly includes a support rod 12 fixedly mounted on the reciprocating mechanism, and a support tube 13 is rotatably mounted on the support rod 12. Cylinders 15 hinged to the reciprocating mechanism are hinged on both sides of the support tube 13. The support tube 13 is rotatably connected to the drill bit 14 and is connected to the dust removal mechanism.

[0035] See also Figures 1-2 、 Figure 4The bottom of the frame 1 is provided with a track, which can be controlled by a track control device to move forward or backward. The drill bit 14 is located at the front end of the frame 1 and can crush the mining area. The support pipe 13 is provided with a motor, and the output shaft of the motor is connected with the rotating shaft of the drill bit 14. When mining is needed, the frame 1 moves to the specified position so that the drill bit 14 contacts the mining area. At the same time, the motor works and drives the drill bit 14 to rotate. During the rotation, the frame 1 moves towards the mining area, so that the drill bit 14 drills into the mining area to perform the mining action. The deflection angle of the support pipe 13 in the vertical direction can be adjusted by the cylinder 15, so that the drill bit 14 changes the direction to mine the ore at different heights. The motor is an application of the prior art, and the present application will not be described in detail.

[0036] The frame 1 is also provided with a reciprocating mechanism connected with the angle adjusting assembly. The reciprocating mechanism can control the drill bit 14 to reciprocate by the angle adjusting assembly. The reciprocating mechanism includes a second rotating rod 9 rotatably installed on the frame 1. The second rotating rod 9 is fixed with a rotating tooth disc 10. The second rotating rod 9 is also fixed with a rotating plate 11 rotatably connected with the frame 1. The rotating plate 11 is fixedly connected with the support rod 12 and hinged with the cylinder 15. The rotating plate 11 is connected with the driving assembly. The frame 1 is provided with a meshing assembly connected with the rotating tooth disc 10 and the collecting assembly. The meshing assembly includes a transmission rod 6 rotatably installed on the frame 1 and symmetrically arranged. The two transmission rods 6 are fixed with gears 7 that are meshed with each other. The gears 7 are fixed with a plurality of limiting rods 8 arranged at equal intervals in a circle. The limiting rods 8 cooperate with the rotating tooth disc 10. The transmission rod 6 is connected with the collecting assembly.

[0037] Please refer to Figures 1-2 , Figures 4-7Further, the second rotating rod 9 is located on the central axis of the frame 1, and the two gears 7 are located on the two sides of the central axis. In order to expand the mining range, the drill bit 14 can swing back and forth in the horizontal direction after drilling into the ore. In the initial state, the two gears 7 are engaged with each other. A motor is arranged on the frame 1 and connected with one of the transmission rods 6. When the drill bit 14 is mining, the motor can drive the transmission rod 6 to rotate, and drive one of the gears 7 fixedly connected with the transmission rod 6 to rotate, so that the other gear 7 engaged with the gear 7 rotates in the opposite direction. The gear 7 also drives the limiting rod 8 to move. When the limiting rod 8 located on one of the gears 7 cooperates with the rotating tooth disc 10, the limiting rod 8 located on the other gear 7 is separated from the rotating tooth disc 10. Under the action of the limiting rod 8, the rotating tooth disc 10 is controlled to rotate, thereby driving the second rotating rod 9 to rotate, so that the rotating plate 11 rotates by a certain angle, so that the drill bit 14 deflects by a certain angle towards one side. When the limiting rod 8 is separated from the rotating tooth disc 10, the limiting rod 8 located on the other gear 7 is just rotated to the position cooperating with the rotating tooth disc 10, thereby driving the rotating tooth disc 10 to rotate in the opposite direction, so as to drive the rotating plate 11 to rotate in the opposite direction through the second rotating rod 9, so that the drill bit 14 deflects by a certain angle towards the other side. The above steps are repeated, thereby realizing the effect of expanding the mining range of the drill bit 14.

[0038] A collecting assembly is arranged on the bucket 2 and connected with the reciprocating mechanism. The collecting assembly is used for collecting the soil drilled by the drill bit 14. The collecting assembly comprises a first rotating rod 3 which is rotatably arranged on the bucket 2 and symmetrically arranged. A rotating disc 4 is fixed on the first rotating rod 3. A belt 5 connected with the transmission rod 6 is sleeved on the first rotating rod 3.

[0039] Please refer to Figures 1-2 , Figures 4-6 Further, in the mining process, the ore after the action of the drill bit 14 will be broken and fall to the ground. In order to improve the mining efficiency, the drilled ore needs to be transported to the designated position to prevent the ore from piling up and causing the problem of being unable to mine. The bucket 2 is arranged on the same side of the drill bit 14 on the frame 1 and below the drill bit 14. When the drill bit 14 works, the ore will fall to the ground. The bucket 2 can shovel part of the ore into the bucket 2. In order to increase the collection amount of the ore, when the transmission rod 6 rotates, the first rotating rod 3 is driven to rotate through the belt 5, thereby driving the rotating disc 4 to rotate. The rotating directions of the two rotating discs 4 are opposite. The two rotating discs 4 can push the ore into the bucket 2, thereby increasing the collection efficiency of the ore.

[0040] Preferably, a conveying belt (not shown in the figure) is arranged at the bottom of the frame 1 and connected with the bucket 2. Under the action of the rotating disc 4, the ore will be continuously pushed onto the conveying belt and conveyed to a designated position by the conveying belt, thereby achieving the effect that the mined ore does not need to be collected during shutdown.

[0041] A dust removal mechanism is arranged on the frame 1, and the dust removal mechanism comprises a fan 16 fixedly installed on the support pipe 13, a conduit 20 fixed on the fan 16, a spray head 21 fixed at one end of the conduit 20 towards the fan 16, a pump liquid assembly arranged on the frame 1 and connected with the conduit 20, and the pump liquid assembly is connected with the driving assembly. The pump liquid assembly comprises a water tank 18 fixedly installed on the frame 1, a piston cylinder 19 fixedly installed on the frame 1 and connected with the conduit 20, and a piston 22 movably installed in the piston cylinder 19, and the piston 22 is connected with the driving assembly.

[0042] Please refer to Figures 1-2 、 Figure 4 、 Figure 8 Furthermore, in the process of mining ore, a large amount of dust will be generated. In order to protect the health of the mining personnel and the environment of the mining area, dust removal is needed during the mining process. At this time, the fan 16 can be turned on. Under the action of the fan 16, the dust is collected. At the same time, when the rotating plate 11 rotates, the driving assembly is driven to move, so that the piston 22 arranged in the piston cylinder 19 reciprocates in the piston cylinder 19. The piston cylinder 19 is provided with two one-way valves. The conduit 20 can be divided into two parts. One end of the first part is connected with one of the one-way valves, and the other end is connected with the water tank 18. The second part is connected with the other one-way valve, and the other end is connected with the spray head 21. When the piston 22 moves, the air pressure in the piston cylinder 19 will change, so that the water in the water tank 18 is sucked into the piston cylinder 19 through the conduit 20, and then the water in the piston cylinder 19 is conveyed to the spray head 21 through the conduit 20. The water will be sprayed from the spray head 21 and act on the air, thereby adsorbing the dust in the air to achieve the effect of dust removal. Since the conduit 20 is fixed on the fan 16, and the fan 16 is fixed on the support pipe 13, when the support pipe 13 moves, the conduit 20 moves synchronously, thereby ensuring that the fan 16 and the spray head 21 are always consistent with the orientation of the drill bit 14, so that the dust removal effect is better.

[0043] Preferably, a pipe (not shown in the figure) can be arranged on the air outlet of the fan 16. Under the action of the pipe, the dust absorbed by the fan 16 is conveyed to a designated position. The water sprayed by the spray head 21 can also cool the drill bit 14, thereby avoiding the problem that the drill bit 14 is overheated and damaged during mining.

[0044] The frame 1 is further provided with a driving assembly connected with the dust removing mechanism and the reciprocating mechanism, the reciprocating mechanism can drive the dust removing mechanism to move through the driving assembly, the driving assembly comprises a rotating disc 17 fixedly installed on the rotating plate 11, a connecting rod 24 is rotatably installed on the rotating disc 17, and the connecting rod 24 is hingedly connected with a movable rod 23, and the movable rod 23 is fixedly connected with the piston 22.

[0045] Please refer to Figures 1-5 、 Figure 8 Finally, when the rotating plate 11 reciprocatingly rotates, the rotating disc 17 is driven to reciprocatingly rotate, so that the connecting rod 24 is driven to move, under the action of the connecting rod 24, the movable rod 23 is driven to move, so that the piston 22 is driven to reciprocatingly move in the piston cylinder 19.
