[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In the present invention, the natural gas tank, combustion base, water furnace, steam drive box and steam cylinder can utilize natural gas to drive the spiral drill bit to rotate, which makes the working process of the down-the-hole drill more environmentally friendly, reduces the emission of greenhouse gases, and has little impact on the air quality of the working environment. The natural gas combustion process hardly produces harmful gases, and the exhausted gas contains almost no sulfide or dust, which has almost no impact on the health of the operators and the environment. Using natural gas fuel to replace gasoline, diesel and other fuels can effectively improve the air quality near the working environment.

[0017] 2. In the present invention, natural gas is used to drive the spiral drill bit to work, which can save the use cost of the down-the-hole drill. As the extraction efficiency of natural gas increases, the price of natural gas is decreasing relative to other energy sources. Using natural gas as a driving energy source can save the cost of drilling rig operation, and the natural gas combustion efficiency is higher, and the energy utilization rate is also higher.

[0018] 3. In the present invention, the process of using natural gas energy to drive the down-the-hole drill is safer. Compared with liquids such as gasoline and diesel, once a leak occurs, it will gather on the ground or the surface of the device. Once it encounters an open flame, it will cause a fire, resulting in serious consequences. The density of natural gas is lower than that of air. Even if a leak occurs, natural gas will quickly diffuse upward, evaporate in the air, and be quickly diluted by the air. Even if it encounters an open flame, it will not burn or explode. It is relatively safer when encountering a leak, and it also makes the process of use by the operator safer.

[0019] 4. In the present invention, the fan can allow a large amount of air to enter the interior of the combustion base, allowing the natural gas inside the combustion base to burn more fully. The electric valve can control the speed at which the natural gas in the natural gas tank enters the interior of the combustion base. When more natural gas and air enter the interior of the combustion base, the combustion efficiency will be higher, the efficiency of heating the water inside the water boiler will be higher, the efficiency of the water vapor in the water boiler overflowing out will also be higher, and the frequency of the back-and-forth movement of the piston head inside the steam cylinder will also be higher, so that the spiral drill bit will rotate faster and the working efficiency of the down-the-hole drill will be higher.

[0020] 5. In the present invention, the crawler tracks can allow the device to adapt to different terrains when moving, making the device applicable to more scenarios. The conveyor belt and receiving hopper can transport part of the waste generated during the drilling process of the spiral drill backwards to prevent the waste from accumulating in front of the crawler tracks and affecting the travel route of the crawler tracks, making the device more convenient to move during work and making the device more efficient. It is also convenient for people to clean up the waste generated during the drilling process and to manage the working environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] It should be noted that the present invention is an integrated down-the-hole drill driven by natural gas. When in use, the sealing cover 7 is opened, water is added to the water furnace 18 through the water inlet pipe 19, and the electric valve 47 opens the gas outlet head 45 at the upper end of the natural gas tank 20. The natural gas in the natural gas tank 20 is transported into the curved pipe 53 inside the combustion base 50 through the natural gas delivery pipe 48, and then sprayed out from the nozzle 54. The electric spark igniter 55 ignites to generate a flame in the combustion base 50 to heat the water furnace 18. At the same time, the fan 52 is started to transport air to the combustion base 50, so that the natural gas inside the combustion base 50 can burn more fully, and the exhaust gas from the combustion is discharged from the flue gas pipe 4. The water vapor in the water furnace 18 enters the steam delivery pipe 17. The steam in the steam cylinder 16 is then pushed into the cavity 34 inside the driving box 27, and then enters the internal front side of the steam cylinder 16 through the No. 2 connecting pipe 37, pushing the piston head 39 to move backward inside the steam cylinder 16, and the piston head 39 will drive the piston rod 26 to move backward. At the same time, the paddle 43 above the front end of the piston rod 26 will paddle the rear baffle 41 backward. The baffle 41 rotates between the two sets of frame rods 33 and drives the movable rod 29 to move forward through the rotating splint 40 at the upper end. The movable rod 29 will drive the movable cap 35 to move forward at the bottom of the cavity 34, and move away from the upper end of the No. 1 connecting pipe 36, connecting the discharge pipe 38 with the No. 2 connecting pipe 37. At this time, the steam will pass through the No. 1 connecting pipe 36 into the internal rear side of the steam cylinder 16, pushing the piston head 39 in The interior of the steam cylinder 16 moves forward, and the steam on the front side of the steam cylinder 16 will enter the discharge pipe 38 through the No. 2 connecting pipe 37 and the movable cap 35, and be discharged outward through the steam pipe 5. The piston rod 26 moves forward through the piston head 39, and the front baffle 41 is pushed forward through the paddle 43 above the front end, so that the movable rod 29 moves backward, and then drives the movable cap 35 to move backward, and then the No. 1 connecting pipe 36 is connected to the discharge pipe 38, and the steam can enter the front side of the steam cylinder 16 through the No. 2 connecting pipe 37 again. This cycle is repeated, so that the piston rod 26 can move back and forth, and the piston rod 26 will drive the rocker 15 to move back and forth, and the rear end of the rocker 15 will rotate the connector 25 in front of the piston rod 26. The front end of the rocker 15 rotates on the side wall of the disc 14 through the rotating shaft 24, so that the rocker 15 can drive the disc 14 to rotate on the side wall of the second fixing frame 23. The rotation of the disc 14 can drive the second bevel gear 13 to rotate in the middle of the first fixing frame 21 through the rotating connecting rod 22. The second bevel gear 13 then drives the first bevel gear 12 to rotate. The first bevel gear 12 drives the outer wall of the outer shell 1 of the spiral drill bit 2 to rotate to perform the drilling work. Part of the waste generated during the drilling process of the spiral drill bit 2 will fall into the inside of the receiving hopper 8, and then slide to the upper end of the conveyor belt 58. The motor 62 inside the chassis 56 is started, and the conveyor belt 58 is driven to rotate through the driving gear 61 and the driven gear 60 to transport the waste at the upper end of the conveyor belt 58 to the rear of the device.
