Description

Technical Field

[0001] This application relates to the technical field of drill pipe desliming, and in particular to a spiral drill pipe desliming device. Background Technology

[0002] During the drilling process, long auger drill rods often accumulate a large amount of soil. As the auger drill rod is spiraled upwards, the soil is also lifted into the air. Consequently, a large amount of soil will fall off the auger drill rod due to the vibration generated during the lifting process, polluting the surrounding environment and making the area around the auger drill rod very unsafe.

[0003] A spiral drill pipe consists of a drill pipe body and spiral blades fixedly wound around the side of the drill pipe body. Because the drill pipe body is vertical and the spiral blades around the drill pipe body are spiral-shaped, it is difficult for workers to clean the mud attached to the drill pipe body and the spiral blades at the same time. Moreover, some mud is easily left on the spiral blades and the drill pipe body after cleaning, resulting in poor mud removal effect. Therefore, it needs to be improved. Summary of the Invention

[0004] To facilitate the desliming of auger drill pipes and improve the desliming effect, this application provides an auger drill pipe desliming device.

[0005] This application provides a desliming device for auger drill pipes, employing the following technical solution: An auger drill pipe desliming device includes a mounting frame located at the contact point between the auger drill pipe and the ground. The mounting frame is equipped with a first serrated plate, a second serrated plate, a mud scraper, a cleaning brush, and a water scraper, arranged spirally upwards and inserted into the spiral cavity of the auger blade. All the first serrated plate, second serrated plate, mud scraper, cleaning brush, and water scraper are arranged in a "C" shape. The tops of the first serrated plate, second serrated plate, mud scraper, cleaning brush, and water scraper abut against the lower surface of the auger blade, and the bottoms of the first serrated plate, second serrated plate, mud scraper, cleaning brush, and water scraper abut against the upper surface of the auger blade. The outer walls of the first serrated plate, second serrated plate, mud scraper, cleaning brush, and water scraper abut against the side wall of the drill pipe body. Each of the first serrated plate, second serrated plate, and mud scraper is equipped with a water spraying mechanism for spraying water onto itself, the auger blade, and the drill pipe body.

[0006] Optionally, both the first and second sawtooth plates include a mounting plate arranged in a "C" shape and mounted on a mounting frame. Both the upper and lower ends of the mounting plate are equipped with mud scraping teeth for abutting the spiral blade. The outer side wall of the mounting plate is equipped with mud scraping teeth for abutting the side wall of the drill pipe body. The mud scraping teeth in the first sawtooth plate and the mud scraping teeth in the second sawtooth plate are staggered. The length of the mud scraping teeth in the first sawtooth plate is greater than the length of the mud scraping teeth in the second sawtooth plate.

[0007] Optionally, the mounting frame includes several connecting plates that are fixedly connected to the first serrated plate, the second serrated plate, the sludge scraper, the cleaning brush, and the squeegee. All the connecting plates are connected to several reinforcing plates arranged in a "C" shape, and all the reinforcing plates are connected to the same bracket supported on the ground.

[0008] Optionally, the bracket is equipped with several vertically arranged fixing cylinders, and the fixing cylinders are slidably embedded in the vertical direction with pins for insertion into the ground.

[0009] Optionally, a fixing plate is installed on the top of the pin, and a spring is wound around the pin between the fixing plate and the fixing cylinder; when the spring wound around the pin is in its natural state between the fixing plate and the fixing cylinder, the lowest point of the pin will be higher than the lowest point of the bracket.

[0010] Optionally, the water spraying mechanism includes a water tank mounted on a mounting frame, three spray pipes respectively mounted on a first sawtooth plate, a second sawtooth plate, and a mud scraper, a water pump mounted on the water tank, the water pump's inlet pipe connected to the inside of the water tank, the water pump's outlet pipe connected to all the spray pipes via a connecting pipe, and the spray pipes having several spray holes.

[0011] Optionally, the mounting frame is equipped with an upward-facing collection box, which has a mud guide plate for guiding the mud on the spiral blade into the collection box. The lower end of the mud guide plate is located at the top of the collection box, and the upper end of the mud guide plate is located directly below the first serrated plate, the second serrated plate, the mud scraper, the cleaning brush, and the water scraper.

[0012] Optionally, the height of the upper surface of the guide plate gradually decreases from the left and right sides of the guide plate to the middle of the guide plate.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. When the auger drill rod spirals upward, the first sawtooth plate, the second sawtooth plate, and the mud scraper will successively scrape off the mud attached to the side wall of the drill rod body and the mud attached to the upper and lower surfaces of the auger blade. The water pump will draw water from the water tank and pass it into the jet pipe through the connecting pipe. The water in the jet pipe will be sprayed through the jet hole, so that the mud attached to the first sawtooth plate, the second sawtooth plate, the mud scraper, the drill rod body, and the auger blade will be washed off. The cleaning brush and the water scraper will brush off the water and residual mud attached to the side wall of the drill rod body and the water and residual mud attached to the upper and lower surfaces of the auger blade.

[0015] 2. The scraped water and soil will fall onto the surface of the guide plate and slide down into the collection box, thus achieving the collection of soil and water;

[0016] 3. During the soil removal process, the pins will be vertically inserted into the ground, so that the support is locked and fixed on the ground, ensuring the stability of the first saw blade, the second saw blade, the mud scraper, the drill rod body and the auger blade when scraping soil and water.

[0023] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0024] This application discloses a auger drill pipe desliming device. For example... Figures 1 to 3 As shown, a spiral drill rod desliming device includes a mounting frame 1. The mounting frame 1 is equipped with a first serrated plate 11, a second serrated plate 12, a mud scraper 13, a cleaning brush 14, and a water scraper 15 arranged spirally upwards. The first serrated plate 11, the second serrated plate 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 are all arranged in a "C" shape.

[0025] Before the auger drill rod moves spirally upward, the worker moves the mounting frame 1 to the point where the auger drill rod contacts the ground, and inserts the first toothed plate 11, the second toothed plate 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 into the spiral cavity of the auger blade. The tops of the first toothed plate 11, the second toothed plate 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 all abut against the lower surface of the auger blade, and the bottoms of the first toothed plate 11, the second toothed plate 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 all abut against the upper surface of the auger blade. The outer walls of the first toothed plate 11, the second toothed plate 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 abut against the side wall of the drill rod body. A water spraying mechanism 2 is installed on the first toothed plate 11, the second toothed plate 12, and the mud scraper 13.

[0026] As the auger drill pipe spirals upward, the first saw blade 11 will initially scrape and tear away the soil adhering to the side wall of the drill pipe body and the upper and lower surfaces of the auger blade. The second saw blade 12 will again scrape and tear away the soil adhering to the side wall of the drill pipe body and the upper and lower surfaces of the auger blade. The mud scraper 13 will more thoroughly scrape away the soil adhering to the side wall of the drill pipe body and the upper and lower surfaces of the auger blade.

[0027] During the process of scraping away soil using the first sawtooth plate 11, the second sawtooth plate 12, and the scraper plate 13, the water spraying mechanism 2 on the first sawtooth plate 11, the second sawtooth plate 12, the scraper plate 13, the drill rod body, and the spiral blade will spray water onto the first sawtooth plate 11, the second sawtooth plate 12, the scraper plate 13, the drill rod body, and the spiral blade, thereby improving the soil cleaning effect.

[0028] Then, the cleaning brush 14 will remove the water and residual mud adhering to the side wall of the drill pipe body, as well as the water and residual mud adhering to the upper and lower surfaces of the auger blade. The scraper 15 will more thoroughly scrape off the water and residual mud adhering to the side wall of the drill pipe body, as well as the water and residual mud adhering to the upper and lower surfaces of the auger blade. The scraped water will detach from the auger drill pipe along with the scraped mud to prevent the mud from falling back down after the auger drill pipe is raised to a high position.

[0029] like Figures 3 to 5 As shown, the mounting frame 1 includes several connecting plates 16, each welded to a first serrated plate 11, a second serrated plate 12, a mud scraper 13, a cleaning brush 14, and a squeegee 15. All connecting plates 16 are welded together with several reinforcing plates 17 arranged in a "C" shape. All reinforcing plates 17 are welded together with the same bracket 18 supported on the ground, thereby ensuring the stability of the first serrated plate 11, the second serrated plate 12, the mud scraper 13, the cleaning brush 14, and the squeegee 15 during the mud scraping process.

[0030] like Figure 2 and Figure 3 As shown, the water spraying mechanism 2 includes a water tank 21 mounted on a bracket 18 and three spray pipes 24 respectively mounted on a first serrated plate 11, a second serrated plate 12 and a scraper plate 13. A water pump 22 is mounted on the water tank 21. The inlet pipe of the water pump 22 is connected to the inside of the water tank 21, and the outlet pipe of the water pump 22 is connected to all the spray pipes 24 through a connecting pipe 23. The spray pipes 24 are provided with a number of spray holes 241.

[0031] During the soil removal process, the water pump 22 draws water from the water tank 21 and sends it through the connecting pipe 23 into the jet pipe 24. The water in the jet pipe 24 is then sprayed through the jet holes 241 onto the first sawtooth plate 11, the second sawtooth plate 12, the mud scraper 13, the drill rod body, and the spiral blade, causing the soil adhering to the first sawtooth plate 11, the second sawtooth plate 12, the mud scraper 13, the drill rod body, and the spiral blade to be washed away.

[0032] A collection box 3 with its opening facing upwards is installed on the bracket 18. The collection box 3 is provided with a mud guide plate 31 that is set at an inclination. The lower end of the mud guide plate 31 is located at the top of the collection box 3, and the upper end of the mud guide plate 31 is located directly below the first serrated plate 11, the second serrated plate 12, the mud scraper 13, the cleaning brush 14 and the water scraper 15.

[0033] During the mud removal process, the mud and water scraped off by the top of the first saw blade 11, the second saw blade 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 will fall onto the upper surface of the mud guide plate 31, the side wall of the drill rod body, or the bottom of the first saw blade 11, the second saw blade 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15. The mud scraped off by the outer side of the first saw blade 11, the second saw blade 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 will also fall onto the bottom of the drill rod body. Soil and water will fall onto the upper surface of the guide plate 31 or the bottom of the first serrated plate 11, the second serrated plate 12, the scraper 13, the cleaning brush 14, and the water scraper 15. The soil and water scraped off by the bottom of the first serrated plate 11, the second serrated plate 12, the scraper 13, the cleaning brush 14, and the water scraper 15 will fall onto the upper surface of the guide plate 31. The scraped soil and water will slide down the upper surface of the guide plate 31 and flow into the collection box 3, thus realizing the collection of soil and water.

[0034] The height of the upper surface of the guide plate 31 gradually decreases from the left and right sides to the middle of the guide plate 31, making it difficult for mud and water falling onto the upper surface of the guide plate 31 to fall through the edges of the guide plate 31.

[0035] The bracket 18 is equipped with several vertically arranged fixing cylinders 181. The fixing cylinders 181 are slidably embedded with pins 182 in the vertical direction. The pins 182 can be vertically inserted into the ground, so that the bracket 18 is locked and fixed on the ground, ensuring the stability of the first sawtooth plate 11, the second sawtooth plate 12, the mud scraper 13, the drill rod body and the spiral blade when scraping mud and water.

[0036] A fixing plate 183 is welded to the top of the pin 182, and a spring 184 is wound around the pin 182 between the fixing plate 183 and the fixing cylinder 181. When the spring 184 wound around the pin 182 is in its natural state between the fixing plate 183 and the fixing cylinder 181, the lowest point of the pin 182 will be higher than the lowest point of the bracket 18, so that the pin 182 is detached from the ground, ensuring that workers are not easily pierced by the pin 182 when handling the bracket 18.

[0037] like Figures 3 to 5 As shown, both the first sawtooth plate 11 and the second sawtooth plate 12 include a mounting plate 111 that is arranged in a "C" shape and welded to the connecting plate 16. Both the upper and lower ends of the mounting plate 111 are equipped with mud scraping teeth 112. The outer side wall of the mounting plate 111 is also equipped with mud scraping teeth 112. The mud scraping teeth 112 can scrape off and tear the mud adhering to the side wall of the drill pipe body and the mud adhering to the upper and lower surfaces of the spiral blade.

[0038] The scraping teeth 112 in the first saw blade 11 and the scraping teeth 112 in the second saw blade 12 are staggered, so that the second saw blade 12 can scrape off the mud that was not scraped by the first saw blade 11. The two work together to improve the cleaning effect of the mud.

[0039] The length of the scraping teeth 112 in the first saw blade 11 is greater than the length of the scraping teeth 112 in the second saw blade 12. Therefore, the soil torn by the scraping teeth 112 in the first saw blade 11 will be thicker, and the soil scraped off by the mounting plate 111 in the first saw blade 11 will be thinner, reducing the resistance encountered by the first saw blade 11 during the scraping process. Then, the mounting plate 111 in the second saw blade 12 will scrape off a layer of soil that was not scraped off by the mounting plate 111 in the first saw blade 11, realizing the layer-by-layer peeling of soil, thereby improving the soil cleaning effect.

[0040] The implementation principle of the auger drill rod desliming device in this application embodiment is as follows: Before the auger drill rod moves spirally upward, the worker moves the mounting frame 1 to the contact point between the auger drill rod and the ground, and vertically inserts the pin 182 into the ground, so that the bracket 18 is locked and fixed on the ground; then the worker inserts the first serrated plate 11, the second serrated plate 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 into the spiral cavity of the auger blade. The tops of the first serrated plate 11, the second serrated plate 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 all abut against the lower surface of the auger blade, the bottoms of the first serrated plate 11, the second serrated plate 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 all abut against the upper surface of the auger blade, and the outer walls of the first serrated plate 11, the second serrated plate 12, the mud scraper 13, the cleaning brush 14, and the water scraper 15 abut against the side wall of the drill rod body.

[0041] As the auger drill pipe spirals upward, the first saw blade 11 will initially scrape and tear away the soil adhering to the side wall of the drill pipe body and the upper and lower surfaces of the auger blade. The second saw blade 12 will again scrape and tear away the soil adhering to the side wall of the drill pipe body and the upper and lower surfaces of the auger blade. The mud scraper 13 will more thoroughly scrape away the soil adhering to the side wall of the drill pipe body and the upper and lower surfaces of the auger blade.

[0042] During the process of scraping away soil by the first saw blade 11, the second saw blade 12, and the scraper blade 13, the water pump 22 draws water from the water tank 21 and sends it into the jet pipe 24 through the connecting pipe 23. The water in the jet pipe 24 is then sprayed through the jet hole 241 onto the first saw blade 11, the second saw blade 12, the scraper blade 13, the drill rod body, and the spiral blade, causing the soil attached to the first saw blade 11, the second saw blade 12, the scraper blade 13, the drill rod body, and the spiral blade to be washed away.

[0043] Then, the cleaning brush 14 will remove the water and residual mud adhering to the side wall of the drill pipe body, as well as the water and residual mud adhering to the upper and lower surfaces of the spiral blade. The scraper 15 will more thoroughly scrape away the water and residual mud adhering to the side wall of the drill pipe body, as well as the water and residual mud adhering to the upper and lower surfaces of the spiral blade. The scraped water will detach from the spiral drill pipe along with the scraped mud, and the scraped mud and water will slide down the upper surface of the mud guide plate 31 and flow into the collection box 3, thus realizing the collection of mud and water.

[0044] In summary, this application facilitates the desliming of auger drill pipes and improves the desliming effect on auger drill pipes.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
