[0002] The impactor is a necessary tool for oil drilling and production. The use of a large-aperture safety oil drilling and production impactor can ensure the smooth discharge of soil debris in the drilling. When the impactor is working, the drill bit will generate heat due to friction. The continuous high-temperature operation of the drill bit will affect the service life of the drill bit, so a cooling structure is set inside the impactor; For example, the Chinese invention patent with the authorization announcement number CN118223790B discloses a large-aperture safety oil drilling impactor, which belongs to the technical field of impactors, including an impactor outer sleeve, the drilling end of the impactor outer sleeve is equipped with a coolant supply mechanism, the outer side of the coolant supply mechanism is provided with a self-expanding mechanism, the coolant supply mechanism includes a cavity sleeve and an internal coolant supply tank, the self-expanding mechanism includes a partition disc and outward turning blocks arranged in a circle on the outer surface of the partition disc, and the coolant supply mechanism also includes a first electric telescopic rod arranged at the bottom of the coolant supply tank. The front drill end can be expanded like an umbrella in cooperation with the telescopic effect of the first electric telescopic rod, which can not only directly dump out the debris entering the drill end, but also use the separately expanded branch structure to fully dissipate heat, which is different from the integrated impact drill bit in the prior art, and can better dissipate the heat in the component and effectively reduce the risk of overheating of its impact end; However, the existing large-aperture safety oil drilling impactors still have the following problems: For example, a drilling impactor proposed in the utility model with the authorization announcement number CN216517773U, when impacting and knocking rock and soil, the soil that has not been squeezed into other soil layers enters the interior of the impactor for storage, but it is not convenient to compact the soil that enters the interior of the impactor, so it is not convenient to store more soil; It is inconvenient to remove the dirt on the impact head before automatically applying the protective fluid, so it is not convenient to cool down efficiently. Therefore, we propose a large-aperture safe oil drilling impactor to solve the above problems. Summary of the invention

[0003] The purpose of the present invention is to provide a large-aperture safe oil drilling impactor to solve the problem that the existing large-aperture safe oil drilling impactor proposed in the above background technology, when impacting and knocking rock and soil, the soil that has not been squeezed into other soil layers enters the interior of the impactor for storage, but it is inconvenient to compact the soil entering the interior of the impactor, thereby making it inconvenient to store more soil, and it is inconvenient to remove the soil on the impact head before automatically applying the protective liquid, thereby making it inconvenient to efficiently cool down.

A high-pressure water pump is fixed to the top of the inner part of the second outer sleeve, and a folded-line pipe is fixed to the output end of the high-pressure water pump. An annular pipe is fixed to the bottom end of the folded-line pipe, and a water pipe is fixed at an equal angle to the bottom end of the annular pipe. A liquid spraying mechanism is arranged on the outside of the cleaning mechanism, and the liquid spraying mechanism comprises a protective liquid storage tank, an L-shaped tube, a connecting tube, a storage air bag and a liquid spraying tube; a protective liquid storage tank is fixed to the inner wall of the second outer sleeve, and an L-shaped tube is fixed to the top of the protective liquid storage tank; a connecting tube is fixed to the bottom end of the protective liquid storage tank, and a storage air bag is fixed to the bottom end of the connecting tube; and a liquid spraying tube is fixed to the bottom end of the storage air bag.

[0005] By adopting the above technical solution, the linkage mechanism drives the impact head and the hammer pressure airbag to rise and fall simultaneously. The hammer pressure airbag is used to hammer the soil while the impact head is raised and lowered, so that more soil can be stored inside the first outer sleeve. Before automatically spraying the protective liquid, the soil adhered to the impact head is removed by the cleaning mechanism, and dual cooling by flushing and spraying the protective liquid is used to ensure the cooling effect.

[0006] Preferably, both left and right ends of the lifting frame are sawtooth structures, and the lifting frame and the first outer sleeve form a lifting structure through a toothed disc, and the lifting of the lifting frame can drive the first connecting rod and the second connecting rod to lift.

[0012] Preferably, the bottom ends of the water pipe and the spray pipe are both located at the bottom end of the second outer sleeve, and the water pipe is located inside the spray pipe, and the spraying work is performed through the water pipe and the spray pipe arranged at equal angles.

[0013] Compared with the prior art, the invention has the following beneficial effects: the linkage mechanism of the large-aperture safety oil drilling impactor drives the impact head and the hammer pressure airbag to rise and fall simultaneously, and the hammer pressure airbag is used to hammer the soil while the impact head is being raised and lowered, so that more soil can be stored inside the first outer casing, and the soil adhering to the impact head can be removed by the cleaning mechanism before the protective liquid is automatically sprayed, and the double cooling by flushing and spraying the protective liquid can be used to ensure the cooling effect; 1. When the linkage mechanism consisting of the motor, the gear plate, the lifting frame, the first connecting rod and the second connecting rod drives the impact head, the contact ring and the lifting column to lift and strike the rock, the second connecting rod, the mounting column and the hammer pressure airbag lift and compact the soil entering the first outer casing, so that more soil can be stored inside the first outer casing; When the amount of soil increases, the hammer pressure airbags outside the mounting column are deflated from bottom to top, allowing the hammer pressure airbags to adapt to the changes in soil height; The mounting column is connected to the second connecting rod by a threaded connection, which facilitates the disassembly and assembly of the second connecting rod and the mounting column, thereby facilitating the disassembly and assembly of the mounting column and the hammer pressure airbag; 2. Before spraying the protective liquid on the impact head for cooling, first use a cleaning mechanism consisting of a water tank, a high-pressure water pump, a folded-line pipe, a ring pipe and a water pipe to wash the outer side of the impact head to remove the dirt on the impact head. In the process of washing the impact head, the temperature of the impact head can be reduced. Using high-pressure water to wash the impact head will not use too much water and the amount of water can be controlled; Then, the protective liquid is sprayed using a spray mechanism consisting of a protective liquid storage tank, an L-shaped pipe, a connecting pipe, a storage air bag and a spray pipe to ensure a cooling effect; When the protective liquid does not need to be sprayed, the interior of the storage airbag does not contain the protective liquid, so that even if the contact ring hits the storage airbag when it is lifted, the protective liquid will not be sprayed, which facilitates the control of the spraying of the protective liquid.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0017] Example 1: Please refer to Figure 1-3 , Figure 5-Figure 7 , Fig.10 and Fig.11 The existing large-aperture safety oil drilling impactor is not convenient for compacting the soil entering the impactor when impacting and knocking the rock and soil. In order to solve this technical problem, this embodiment discloses the following technical content; A large-aperture safety type oil drilling impactor, wherein a linkage mechanism is installed inside a first outer casing 1, the linkage mechanism comprises a motor 2, a toothed disc 3, a lifting frame 4, a first connecting rod 5 and a second connecting rod 8, the motor 2 is fixed to the inner rear wall of the first outer casing 1, and the toothed disc 3 is fixed to the output end of the motor 2, the outer end of the toothed disc 3 is meshingly connected with the lifting frame 4, and the first connecting rod 5 is fixed to the lower surface of the lifting frame 4, and the second connecting rod 8 is fixed to the upper surface of the lifting frame 4, a lifting column 25 is fixed below the linkage mechanism, and a contact ring 7 is fixed to the upper surface of the lifting column 25, an impact head 6 is fixed to the bottom end of the lifting column 25, the bottom end of the first connecting rod 5 extends to the inner bottom end of the second outer casing 15, the bottom end of the first connecting rod 5 is fixed to the lifting column 25, and the lifting column 25 runs through the inside of the second outer casing 15; A collecting mechanism is arranged above the linkage mechanism, and the collecting mechanism includes a mounting column 9, a hammer pressure airbag 10, an air valve 11, a soil inlet 12 and a receiving plate 13. The outer side of the mounting column 9 is fixed with a hammer pressure airbag 10, and the inside of the hammer pressure airbag 10 is fixed with an air valve 11. The outer end of the first outer sleeve 1 is provided with a soil inlet 12, and the inside of the first outer sleeve 1 is fixed with a receiving plate 13, and the receiving plate 13 is located above the motor 2, and the inside of the receiving plate 13 is penetrated by a second connecting rod 8; When the casing structure composed of the first outer casing 1, the water tank 14 and the second outer casing 15 rotates to impact the soil, the motor 2 inside the linkage mechanism is started, and the motor 2 drives the toothed disc 3 to rotate. Since the left and right ends of the lifting frame 4 are both sawtooth structures, the toothed disc 3 is meshed and connected with the lifting frame 4. The lifting frame 4 forms a lifting structure with the first outer casing 1 through the toothed disc 3. As the toothed disc 3 rotates, the lifting frame 4 is lifted and lowered inside the first outer casing 1, so that the first connecting rod 5 and the second connecting rod 8 are lifted and lowered, and the impact head 6 connected to the first connecting rod 5 through the lifting column 25 is lifted and lowered to crush the rock; During the impact process, most of the hard-grained rocks are squeezed into the softer strata, and a small part of the other part enters the interior of the first outer casing 1 through the soil inlet 12. The soil is located on the receiving plate 13. The airbag 10 connected to the second connecting rod 8 through the mounting column 9 is raised and lowered. The soil is compacted by the lifting of the airbag 10. A channel for soil flow is left between the airbag 10 and the first outer casing 1. The inner wall of the receiving plate 13 is in contact with the outer side of the second connecting rod 8, and the soil will not enter the bottom of the receiving plate 13. The soil in the middle of the receiving plate 13 will be slightly lifted during the lifting and lowering process of the second connecting rod 8, but it will not affect the overall compaction of the soil. A remotely controllable air valve 11 is installed inside the hammer pressure airbag 10. The opening and closing of the air valve 11 is remotely controlled. As the amount of soil increases, the hammer pressure airbags 10 fixed at equal intervals on the outside of the mounting column 9 are deflated from bottom to top in sequence, so that the hammer pressure airbags 10 can adapt to changes in the amount of soil. The top end of the second connecting rod 8 is threadedly connected with a mounting column 9. When the soil on the receiving plate 13 needs to be removed, the mounting column 9 is rotated to remove the mounting column 9 from the second connecting rod 8, and then the soil is removed by external mechanical equipment; Embodiment 2: The existing large-aperture safety oil drilling impactor is not convenient to remove the dirt on the impact head 6 before automatically applying the protective liquid, so it is not convenient to cool down efficiently. In order to solve this technical problem, this embodiment discloses the following technical content, please refer to Figure 2 , Figure 4 , Figure 8 , Fig.10 and Fig.11 ; A cleaning mechanism is provided below the first outer sleeve 1, and the cleaning mechanism includes a water tank 14, a high-pressure water pump 16, a folded line tube 17, an annular tube 18 and a water pipe 19. The water tank 14 is fixed to the lower surface of the first outer sleeve 1, and a second outer sleeve 15 is fixed below the water tank 14. The high-pressure water pump 16 is fixed to the top of the inner part of the second outer sleeve 15, and the folded line tube 17 is fixed to the output end of the high-pressure water pump 16. The annular tube 18 is fixed to the bottom end of the folded line tube 17, and the water pipe 19 is fixed at an equal angle to the bottom end of the annular tube 18; A liquid spraying mechanism is arranged outside the cleaning mechanism, and the liquid spraying mechanism includes a protective liquid storage tank 20, an L-shaped tube 21, a connecting tube 22, a storage air bag 23 and a liquid spraying tube 24. The protective liquid storage tank 20 is fixed to the inner wall of the second outer sleeve 15, and the L-shaped tube 21 is fixed to the top of the protective liquid storage tank 20. The connecting tube 22 is fixed to the bottom end of the protective liquid storage tank 20, and the storage air bag 23 is fixed to the bottom end of the connecting tube 22. The liquid spraying tube 24 is fixed to the bottom end of the storage air bag 23. The bottom ends of the water pipe 19 and the liquid spraying tube 24 are both located at the bottom end of the second outer sleeve 15, and the water pipe 19 is located on the inner side of the liquid spraying tube 24. When cooling treatment is required, the impact head 6 is cleaned by the cleaning mechanism, and the high-pressure water pump 16 is first started. Under the action of the high-pressure water pump 16, the water inside the water tank 14 is transported to the folded line pipe 17, and then transported to the annular pipe 18 through the folded line pipe 17. The high-pressure water is sprayed out from the inside of the water pipe 19, and the soil entering the inside of the water pipe 19 is first flushed out. Then the high-pressure water impacts the impact head 6, flushes the impact head 6, and removes the soil on the outer surface of the impact head 6. In the process of flushing the impact head 6, the temperature of the impact head 6 is reduced; Then, the liquid spraying mechanism is used to spray the protective liquid to the impact head 6. When the protective liquid needs to be sprayed, the control valve inside the connecting pipe 22 is remotely opened, and the protective liquid inside the protective liquid storage tank 20 enters the storage airbag 23 through the connecting pipe 22. When the impact head 6, the lifting column 25 and the contact ring 7 are raised, the contact ring 7 hits the storage airbag 23, so that the protective liquid inside the storage airbag 23 is sprayed from the inside of the liquid spraying pipe 24 to the impact head 6 to realize automatic coating of the protective liquid, so that a layer of protective coating can be attached to the impact end to reduce the generation of friction and heat. Before the protective liquid is sprayed, the mud entering the liquid spraying pipe 24 is flushed out; A notch is provided at the left end of the contact ring 7 for the folded line tube 17 to pass through, so that the lifting and lowering of the contact ring 7 will not affect the folded line tube 17. When the protective liquid does not need to be sprayed, there is no protective liquid inside the storage airbag 23, so that even if the contact ring 7 continues to lift and squeeze the storage airbag 23, the protective liquid will not be sprayed out; The large-aperture safety oil drilling impactor is taken out from the borehole, the control valve inside the L-shaped tube 21 is opened, the protective liquid is added to the protective liquid storage tank 20 through the L-shaped tube 21, and the cover at the top of the water tank 14 is opened to add cooling water to the water tank 14; It should be noted that the motor 2, impact head 6, air valve 11 and high-pressure water pump 16 are all devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
