When the rotating sleeve 8 rotates, the lubrication component can be driven to run. By setting the lubrication component, lubricating oil can be added to the connecting head 7, so as to maintain the lubrication effect between the drilling rig 6 and the rotating sleeve 8 and the drill bit 9, and prevent mechanical wear caused by the loss of lubricating oil.

The storage tank 11 is fixedly connected to the side wall of the drilling rig 6, and a connecting sleeve 12 is fixedly connected to the bottom thereof. A through hole 46 for connecting the injection pipe 13 and the storage tank 11 is provided in the middle of the connecting sleeve 12. The upper end of the injection pipe 13 is fixedly connected to the bottom of the connecting sleeve 12, and the port is butt-jointed with the lower end of the through hole on the connecting sleeve 12. The lower end of the injection pipe 13 is tilted downward and leads to the connector 7. A center rod 14 is fixedly connected to one side of the storage tank 11, and the bottom of the center rod 14 is rotatably connected to an arc-shaped The arc-shaped plate 15 is fixedly connected to a push plate 16 at the bottom of one end of the arc-shaped plate 15, and a cam 17 is fixedly connected to the outer wall of the rotating sleeve 8, and the cam 17 is located at the upper part of the rotating sleeve 8, and the cam 17 can push the push plate 16 to rotate along the center rod 14 during the rotation process; the connecting sleeve is an arc-shaped hollow sleeve body, the upper part of the through hole 46 on the connecting sleeve 12 is sealed and connected to the liquid outlet pipe of the storage tank 11, and the lower end is sealed and connected to the injection pipe 13, and a sealing plate 21 is movably provided in the connecting sleeve 12, and the sealing plate 21 is a circular plate body with a diameter larger than the diameter of the through hole 46, and the sealing plate 2 The height of 1 matches the hollow area of ​​the connecting sleeve 12, and the top and bottom surfaces of the sealing plate 21 are both provided with sealing pads. A connecting block 20 is provided on one side of the sealing plate 21. The connecting block 20 slides out of the connecting sleeve 12 and is connected to the outer arc surface of one end of the arc plate 15 away from the push plate 16. The connecting block 20 can slide in the connecting sleeve 12 and drive the sealing plate 21 to move in the connecting sleeve to seal or open the through hole 46; a spring 19 is fixedly connected to the inner arc surface of the arc plate 15 away from the push plate 16, and a spring 19 is fixedly connected to the side of the connecting sleeve 12 adjacent to the arc plate 16. The connecting member 18 includes an L-shaped rod horizontally placed above the connecting sleeve 12 and a support plate arranged below one side of the L-shaped rod. One end of the L-shaped rod of the connecting member 18 is fixed on the connecting sleeve 12, and the other end extends horizontally to the inner arc area of ​​the arc plate 15 away from the push plate 16 end, and the support plate extends vertically downward to the inner arc surface of the arc plate 15. The other end of the spring 19 is connected to the support plate of the connecting member 18. When the spring 19 is in a normal state, the sealing plate 21 is located above the through hole 46, and the through hole 46 is sealed and blocked under the action of the sealing gasket.

[0036] When the drilling rig 6 drives the drill bit 9 and the rotating sleeve 8 to rotate, the cam 17 provided on the outer wall of the rotating sleeve 8 can be driven to rotate together. When the cam 17 rotates to one side of the push plate 16, the push plate 16 will be pushed to one side, and the push plate 16 will drive the arc plate 15 to move to one side together when moving. The arc plate 15 will squeeze the spring 19 during the rotation process, and at the same time drive the connecting block 20 and the sealing plate 21 to slide in the connecting sleeve 12. When the sealing plate 21 moves at the through hole 46, the through hole 46 connects the storage tank 11 and the injection pipe 13, and a small amount of lubricating oil flows downward; the drilling rig continues to drive the drill bit 9 and the rotating sleeve 8 When the cam 17 pushes the push plate 15 to rotate to a certain position, it will be separated from the push plate 16.

When the arc plate 15 is reset, the connecting block 20 and the sealing plate 21 can be pushed to reset, so that the through hole 46 is blocked by the sealing plate 21, thereby preventing excessive outflow of lubricating oil. The small amount of lubricating oil that has flowed out previously will drip downward into the injection pipe 13 and flow into the connector 7 through the injection pipe 13, thereby moistening the rotating sleeve 8 and the drill bit 9 below to avoid damage caused by lack of lubricating oil during rotation.

The arc-shaped side plates 28 can be limited by setting the partition 28 to prevent the two groups of arc-shaped side plates 28 from moving excessively to both sides. Racks 27 are respectively provided on the outer sides of the two arc-shaped side plates 28. Each rack 27 extends horizontally from the gap between the two pallets 23 to the outer sides of the pallets, and meshes with the main drive gear 25 and the driven gear 47 respectively.

When the main driving gear 25 rotates, it can drive the rack 27 meshing with the main driving gear 25 to move toward the center, thereby driving the arc-shaped side plate 28 connected to the rack 27 to move toward the center of the guide hole. By setting a limit frame 30, a limiting effect can be provided for the rack 27 when the rack 27 moves to avoid the rack from being offset. When the main driving gear 25 rotates, the gear ring 24 is also driven to rotate. By setting the support plate 23, the gear ring 24 can be lifted to keep the gear ring 24 rotating.

When the striking piece 45 hits the storage tank 11, the lubricating oil in the storage tank 11 will be slightly shaken, which can prevent the lubricating oil from precipitating and facilitate the lubricating oil to flow downward.

[0042] The working process of the present invention is as follows: in order to solve the problem that lubricating oil is easily lost during drilling operation, when drilling operation is required, the transport vehicle 1 can be moved to the location where drilling is required by driving the crawler 2, and then the guide rail 4 is pushed by the hydraulic cylinder 3 to make the guide rail 4 stand upright, and the rotating sleeve 8 and the drill bit 9 are installed at the bottom of the connecting head 7, and the slide plate 5 is moved downward by the crane. During the movement, the drill bit 9 moves along the guide hole on the guide plate 10, and can be limited by the guide plate 10. Then, the rotating sleeve 8 and the drill bit 9 are driven to rotate by starting the drilling rig 6 to drill the ground. When the rotating sleeve 8 rotates, the cam 17 can be driven to rotate at the same time. When the cam 17 rotates to one side of the push plate 16, the push plate 16 will be pushed to move, and the push plate 16 will drive the arc plate 15 to move to one side when moving. The arc plate 15 will squeeze the spring 19 when moving. When the arc plate 15 and the push plate 16 are pushed to one side by the cam 17, the mounting rod 44, the impact plate 45 and the buffer pad can be driven to move to one side. At the same time, the connecting block 20 and the sealing plate 21 can be driven to slide in the connecting sleeve 12 through the arc plate 15, so that a part of the through hole 46 on the connecting sleeve 12 is opened, and a small amount of The lubricating oil flows downward and enters the injection pipe 13; when the cam 17 moves away from one side of the push plate 16, the spring 19 pushes the arc plate 15 to reset to one side. When the arc plate 15 is reset, it can push the connecting block 20 and the sealing plate 21 to reset, thereby blocking the through hole 46, which can prevent the lubricating oil from flowing out too much, and the small amount of lubricating oil that has flowed out previously will drip downward into the injection pipe 13, and flow into the connector 7 through the injection pipe 13, thereby moistening the rotating sleeve 8 and the drill bit 9 below, avoiding damage caused by lack of lubricating oil during rotation, and preventing mechanical wear caused by loss of lubricating oil. When the spring 19 pushes the arc plate 15 to reset to one side, it can drive the mounting rod 44, the impact plate 45 and the buffer pad set at the top of the arc plate 15 to reset together. When the impact plate 45 hits the storage tank 11, the lubricating oil in the storage tank 11 will shake slightly, which can effectively prevent the lubricating oil from precipitating and facilitate maintaining the fluidity of the lubricating oil. When the rotating sleeve 8 rotates, the first bevel gear 36 and the second bevel gear 37 are driven to rotate, and the second bevel gear 37 can drive the first transmission rod 38 and the first gear to rotate. The rotation of the first gear can drive the second transmission rod 41 and the fan blades 43 to rotate. When the fan blades 43 rotate, wind force is generated. The wind force generated by the fan blades 43 can be used to cool the drilling rig 6, so that the temperature of the drilling rig 6 is reduced during operation, thereby preventing the drilling rig 6 from being overheated during operation.

[0043] After drilling is completed, the drilling equipment of the present invention can pull the drill bit 9 upward by a crane. When the drill bit 9 moves upward, the handle is turned to drive the rotating rod 26 at the bottom to rotate. When the rotating rod 26 rotates, it will drive the main driving gear 25 to rotate together. When the main driving gear 25 rotates, it can drive the rack 27 meshing with it to move toward the center. By setting a limit frame 30, a limiting effect can be provided for the rack 27 when the rack 27 moves; when the main driving gear 25 rotates, it will also drive the gear ring 24 to rotate. By setting a support plate 23, the gear ring 24 can be lifted to keep the rotation of the gear ring 24. When the gear ring 24 rotates, it will drive the transmission gear 46 to rotate. The transmission gear 46 rotates in the opposite direction to the driving gear 25, thereby driving the rack meshing with the transmission gear 46 to move toward the center. When the main driving gear 25 and the transmission gear 46 rotate, they will drive the two sets of arc-shaped side plates 28 and the brushes 29 to move toward the center at the same time. When the two sets of brushes 29 contact the outer wall of the drill bit 9, the dirt and other impurities attached to the outer wall of the drill bit 9 can be scraped off, thereby facilitating the cleaning of the drill bit 9; the water tank 31 can be filled with water through the water inlet first, and when the outer wall of the drill bit 9 needs to be cleaned, the valve 33 can be opened to allow the water in the water tank 31 to flow downward into the transmission pipe 32, and then flow into the telescopic pipe 34 through the transmission pipe 32, and the water can be transferred to the nozzle 35 through the telescopic pipe 34, and the water can be sprayed out through the nozzle 35, and the outer wall of the drill bit 9 can be sprayed with water mist, which is more conducive to cleaning the outer wall of the drill bit 9, and by providing the telescopic pipe 34, a connection can be provided between the transmission pipe 32 and the nozzle 35 when the rack 27 moves.

Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
