Specific embodiments

[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0032] A tunneling machine with a dust reduction function in a mine includes a connecting head 1. At one end of the connecting head 1, two tunneling shovels 3 are provided. The ore is collected by the tunneling shovels 3. At the other end of the connecting head 1, a connecting member for connecting with a robotic arm is provided to facilitate driving the tunneling shovels 3 to move through the robotic arm for ore mining.

[0033] In this embodiment, as Figure 1 and Figure 2 , on the outer side of the connecting head 1 near the tunneling shovel 3, a limiting frame 2 is fixed. Inside the limiting frame 2, a driving box 6 is provided. At the end of the driving box 6 away from the connecting head 1, a plurality of hydraulic rods 61 are provided. The hydraulic rods 61 are fixed to the inner wall of the limiting frame 2, and the output ends of the hydraulic rods 61 are fixed to the driving box 6. The driving box 6 is driven to translate by the telescopic movement of the hydraulic rods 61. At the same time, connecting plates 31 are fixed to the outer ends of both tunneling shovels 3. The driving box 6 is connected to the connecting plates 31 through telescopic rods 7 slidably connected inside it, so that when the driving box 6 translates, the two tunneling shovels 3 can be driven to perform an opening and closing movement.

[0034] Specifically, a hinge block is provided on the side of the tunneling shovel 3 close to the limiting frame 2. The tunneling shovel 3 is hinged to the outer end of the limiting frame 2 through the hinge block, so that the tunneling shovel 3 can rotate around the hinge point between the hinge block and the limiting frame 2 as the axis.

[0035] More specifically, the telescopic rod 7 is connected to the inside of the drive box 6 in a limit sliding manner, and the telescopic rod 7 cannot slide out of the inside of the drive box 6 and fall off. Moreover, two telescopic rods 7 are provided and are symmetrically arranged inside the drive box 6. At the same time, a connecting block 71 is provided at one end of the outer end of the telescopic rod 7 close to the connecting plate 31, and the connecting plate 31 is rotatably connected to the connecting block 71. When the tunneling shovel 3 drives the connecting plate 31 to rotate, the connecting plate 31 can rotate around the rotation connection point with the connecting block 71 at the same time. During this process, the connecting plate 31 will drive the telescopic rod 7 to slide and expand inside the drive box 6, so that the drive box 6 is connected to the connecting plate 31 through the telescopic rod 7 to achieve the stability when driving the tunneling shovel 3 to rotate.

[0036] During ore mining, the hydraulic rod 61 is started to drive the drive box 6 to translate toward the side close to the connecting head 1. At this time, the drive box 6 is connected to the connecting plate 31 through the telescopic rod 7, so that the movement of the drive box 6 can generate a pulling force on the connecting plate 31, and then the tunneling shovel 3 rotates around the hinge point between the hinge block and the limit frame 2 as the axis. At this time, the two tunneling shovels 3 rotate and open outward at the same time, so as to facilitate the tunneling shovel 3 to excavate and collect the ore. After the collection is completed, the hydraulic rod 61 drives the drive box 6 to translate toward the side away from the connecting head 1. At this time, the movement of the drive box 6 generates a pushing force on the connecting plate 31, and the two tunneling shovels 3 rotate and close to each other again, so as to reduce the scattering of the ore after mining and improve the single mining volume.

[0037] In a further embodiment, as Figure 1 、 Figure 2 and Figure 3 , spraying components for dust reduction are respectively provided on both sides of the outer end of the limit frame 2, and a water storage cavity 11 is opened inside the connecting head 1 for supplying water to the spraying components. A delivery hose 5 is connected to the bottom of the connecting head 1, and the delivery hose 5 can be connected to a water supply device such as a water tank to supply water to the water storage cavity 11. The water supply device can adopt existing devices.

[0038] Specifically, a piston plate 8 is slidably connected inside the water storage cavity 11. The outer edge of the piston plate 8 fits against the inner wall of the water storage cavity 11, and a push rod 81 is fixed between the piston plate 8 and the drive box 6. When the drive box 6 moves translationally towards the side close to the connector 1, the piston plate 8 can be driven to squeeze the water stored in the water storage cavity 11 and push the water into the spraying assembly. When the drive box 6 moves translationally away from the connector 1, the piston plate 8 can be driven to slide inside the water storage cavity 11. At this time, the air pressure inside the water storage cavity 11 changes, and then the water storage cavity 11 pumps water through the delivery hose 5 to replenish the water inside the water storage cavity 11 again. A check valve is provided inside the delivery hose 5, and the delivery hose 5 can only input water from the water supply device into the water storage cavity 11, and the water will not flow from the delivery hose 5 to the water supply assembly.

[0039] More specifically, the spraying assembly includes a delivery pipe 4 located at the outer end of the limit frame 2. The water inlet end of the delivery pipe 4 is connected to the connector 1 and is in communication with the water storage cavity 11. The water outlet end of the delivery pipe 4 is connected with an atomizing nozzle 41. A fixing member 411 fixed to the limit frame 2 is arranged at the outer end of the atomizing nozzle 41. The fixing member 411 strengthens and protects the atomizing nozzle 41. When the piston plate 8 squeezes the water stored in the water storage cavity 11, the water can be squeezed and input into the delivery pipe 4, and the water flow is atomized and sprayed out through the atomizing nozzle 41 to achieve the dust reduction effect. A check valve is provided inside the delivery pipe 4, and the water flow can only flow from the delivery pipe 4 to the atomizing nozzle 41 and cannot flow from the delivery pipe 4 into the water storage cavity 11.

[0040] When the tunneling shovel 3 is in operation for mining, the two tunneling shovels 3 are in an open state, and at the same time, the drive box 6 is in a state of moving towards the connector 1. As a result, the piston plate 8 squeezes the water stored in the water storage cavity 11, and the water is sprayed out through the spraying assembly to achieve the dust reduction effect. After the tunneling shovel 3 has completed the ore mining, the two tunneling shovels 3 are closed. At this time, the piston plate 8 slides inside the water storage cavity 11, and the water storage cavity 11 absorbs water through the delivery hose 5, so that the surrounding environment can be dusted in advance before the tunneling shovel 3 is ready to mine. After the mining is completed, the inner shell of the water storage cavity 11 can be automatically replenished with water, and the dust reduction and mining functions do not need to operate separately, and the linkage effect is better.
