Description

Technical Field

[0001] The present invention relates to the technical field of core sampling, and particularly relates to a core sampling drill for avoiding frictional overheating. Background Art

[0002] With the rapid development of science and technology, people can use new equipment to explore the soil and rocks underground. By using the samples obtained from exploration and sampling and cooperating with detection devices, the mineral content underground can be detected, which facilitates the later mining of minerals underground. Currently, commonly used core sample sampling devices generally use drills. The drill is used to drill holes in the surface layer of the soil, and then a drill pipe is used to take samples of the core.

[0003] However, when the existing core sampling drill for avoiding frictional overheating is actually used, it needs to be equipped with a water spraying device to facilitate drilling. But in this way, a person is required to specifically control the water spraying device. Through continuous extrusion, the water inside the water spraying device can continuously enter the inside of the drilling machine. This increases the number of construction workers, raises the labor cost, and wastes labor productivity.

[0004] Moreover, in order to ensure that water can flow out normally, the drill pipe must be hollow. However, a hollow drill pipe has the problem of reduced anti-extrusion ability. At the same time, when the drilling machine is used for a long time, the drill pipe will show the phenomenon of frictional overheating, which will affect the service life of the drill pipe. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a core sampling drill for avoiding frictional overheating, which has the advantages of facilitating water spraying while drilling.

[0006] The core sampling drill for avoiding frictional overheating of the present invention includes a base and a motor. A pneumatic component is fixedly installed on the top of the base. A receiving plate is fixedly connected to the top of the pneumatic component. An air outlet pipe is fixedly connected to one end of the pneumatic component. The end of the air outlet pipe far away from the pneumatic component is fixedly connected to a water storage cylinder. A water inlet pipe is fixedly connected to the bottom of the water storage cylinder. The motor is fixedly installed on the top of the receiving plate. The output end at the bottom of the motor is fixedly connected to a rotating shaft. A sleeve is fixedly installed at the bottom of the rotating shaft. A drill pipe is threadedly connected to the bottom of the sleeve. First reinforcing ribs and second reinforcing ribs are fixedly connected to the inner wall of the drill pipe.

[0007] Through the above technical solution design, a motor is used to drive the drill pipe to rotate, which plays a role in drilling the soil. And the pneumatic component is used to inject gas into the water storage cylinder, which can conveniently inject the water inside the water storage cylinder into the sleeve to facilitate wetting the soil and facilitate the drilling of the drill pipe.

[0008] As a further improvement of the present invention, the pneumatic component includes a cylinder fixedly installed on the top surface of the base, a piston rod movably connected to the inner wall of the cylinder, and a piston block fixedly connected to the bottom end of the piston rod.

[0009] As a further improvement of the present invention, one side of the bottom of the cylinder is fixedly connected with an air inlet pipe communicated with the inside of the cylinder, and a first one-way valve is arranged on the surface of the air inlet pipe.

[0010] Through the above technical solution design, the air inlet pipe and the first one-way valve are arranged on the side wall of the cylinder, so as to ensure that the piston rod can slide up and down multiple times in the inner wall of the cylinder to achieve the effect of squeezing out water multiple times.

[0011] As a further improvement of the present invention, the end of the air inlet pipe far away from the cylinder is movably connected with a rubber plug, and a ring is fixedly connected to one side of the rubber plug and the side wall of the cylinder respectively, and a connecting band is fixedly connected between the two rings.

[0012] Through the above technical solution design, the rubber plug is used to conveniently block the pipe orifice of the air inlet pipe to prevent external dust from entering the inside of the air inlet pipe.

[0013] As a further improvement of the present invention, one side of the bottom of the cylinder is fixedly connected with a three-way pipe communicated with the inside of the cylinder, a three-way valve is installed on the surface of the three-way pipe, and a second one-way valve is fixedly installed on the side of the three-way pipe close to the cylinder.

[0014] Through the above technical solution design, with the cooperation of the three-way pipe and the three-way valve, while ensuring that the gas can smoothly enter the water storage cylinder, it is also convenient to intercept and discharge the gas, achieving the effect of saving water.

[0015] As a further improvement of the present invention, a cavity is opened inside the base, the end of the three-way pipe far away from the cylinder penetrates through the cavity, a ventilation groove penetrates through the inside of the cavity, and air outlet holes are evenly opened on the inner wall of the ventilation groove.

[0016] Through the above technical solution design, by opening the cavity and the ventilation groove, the gas discharged by the three-way valve can be used to dissipate heat and cool the surface of the drill pipe, avoiding the reduction of the service life of the drill pipe caused by the friction temperature rise for a long time.

[0017] As a further improvement of the present invention, a fixing block is fixedly connected to the top surface of the base. A threaded rod is threadedly connected to the side wall of the fixing block. One end of the threaded rod is fixedly connected to a fastening block, and a rubber block is fixedly connected to one side of the fastening block.

[0018] Through the design of the above technical solution, by using the fixing block and the threaded rod, the drill rod can be limited and fixed, which is convenient for disassembling and replacing the drill rod.

[0019] As a further improvement of the present invention, a through hole is opened on the top surface of the base, and the top views of the fixing block and the fastening block are both designed as semi-circular arcs.

[0020] As a further improvement of the present invention, a pedal is fixedly connected to the side surface of the base. The top surface of the pedal is designed to be convex, and a roller is fixedly installed on the side surface of the air cylinder through a connecting rod, a fixing frame and a rotating rod.

[0021] Through the design of the above technical solution, by setting a pedal on the side surface of the base and adding a roller, the effect of facilitating the movement of the entire device can be achieved, and it is also convenient to fix the base to ensure the stability during drilling.

[0022] As a further improvement of the present invention, through grooves are evenly opened on the side surface of the bottom end of the drill rod, and scraping blades are evenly fixedly connected to the side surface of the drill rod. The scraping blades and the through grooves are arranged at intervals.

[0023] Through the design of the above technical solution, by opening the through grooves, it is ensured that the water flow can flow out normally. And through the setting of the scraping blades, it can prevent external soil blocks from entering the inside of the drill rod, and at the same time enhance the drilling ability of the drill rod.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0025] 1. By setting a motor on the base in the present invention, the motor can be used to drive the drill rod to rotate to drill the soil. By sliding the piston rod and the piston block inside the pneumatic component up and down, it can cooperate with the air outlet pipe to inject gas into the inside of the water storage cylinder, which is convenient to inject the water inside the water storage cylinder into the inside of the sleeve to moisten the soil and facilitate the drilling of the drill rod. By combining the up and down movement of the piston rod with that of the motor and the drill rod, the redundant labor cost can be reduced, and at the same time, the operation of the device can be made more convenient. By using the mutual cooperation of the first reinforcing rib and the second reinforcing rib, the compressive capacity of the inner wall of the drill rod can be enhanced, thereby achieving the effect of extending the service life of the drill rod.

[0026] 2. By providing an intake pipe and a first one-way valve on the side wall of the air cylinder, the present invention can ensure that the piston rod can slide up and down multiple times inside the inner wall of the air cylinder, achieving the effect of squeezing out water multiple times. The rubber plug is used to conveniently block the nozzle of the intake pipe to prevent external dust from entering the interior of the intake pipe. The cooperation of the three-way pipe and the three-way valve can ensure the smooth entry of gas into the water storage cylinder while also facilitating the interception and discharge of gas, achieving the effect of saving water.

[0027] 3. By providing a cavity and a ventilation groove, the present invention can use the gas discharged by the three-way valve to dissipate heat and cool the surface of the drill pipe, preventing the service life of the drill pipe from being reduced due to long-term frictional heating. The setting of the fixing block and the threaded rod can limit and fix the drill pipe, facilitating the disassembly and replacement of the drill pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In Embodiment 1, a motor 4 is arranged on the base 1 to cooperate with the rotating shaft 5 and the sleeve 7 on the output end of the motor 4 to drive the drill rod 8 to rotate, so as to complete the drilling of the ground. By using the settings of the sleeve 6, the water inlet pipe 9 and the water storage tank, it is convenient to drive the piston rod 202 to slide in the inner wall of the cylinder 201 while moving the drill rod 8 up and down, so that the piston block 203 can squeeze the gas inside the cylinder 201 into the water storage cylinder 10, achieving the effect of allowing water to enter the hollow drill rod 8 from the inner wall of the sleeve 6, playing a role in wetting the soil at the drilling site, facilitating the drill rod 8 to complete the drilling work on the soil. At the same time, by the mutual cooperation of the first reinforcing ribs 30 and the second reinforcing ribs 31, the compressive resistance of the inner wall of the drill rod 8 can be enhanced, and then the service life of the drill rod 8 can be extended. By opening the through grooves 32, it is ensured that the water flow can flow out normally. Through the setting of the scraping blades 33, it is possible to prevent external soil blocks from entering the inside of the drill rod 8, and at the same time, the drilling ability of the drill rod 8 is enhanced.

[0042] Embodiment 2:

[0043] Please refer to Figure 1 、 Figure 3 and Figure 5, one end of the intake pipe 12 far away from the air cylinder 201 is movably connected with a rubber plug 14. One side of the rubber plug 14 and the side wall of the air cylinder 201 are both fixedly connected with a ring 15. A connecting belt 16 is fixedly connected between the two rings 15. One side of the bottom of the air cylinder 201 is fixedly connected with a three-way pipe 17 communicated with the inside of the air cylinder 201. A three-way valve 19 is installed on the surface of the three-way pipe 17. A second one-way valve 18 is fixedly installed on the side of the three-way pipe 17 close to the air cylinder 201. A cavity 20 is opened inside the base 1. One end of the three-way pipe 17 far away from the air cylinder 201 penetrates through the cavity 20. An air vent groove 21 is penetrated inside the cavity 20. Air outlet holes 22 are evenly opened on the inner wall of the air vent groove 21.

[0044] Different from Embodiment 1, by switching the switch of the three-way valve 19, the gas extruded from the inside of the air cylinder 201 can enter the cavity 20 inside the base 1 along the three-way pipe 17, so as to use the gas discharged by the three-way valve 19 to dissipate heat and cool the surface of the drill pipe 8, avoiding the reduction of the service life of the drill pipe 8 caused by the friction temperature rise for a long time.

[0045] Embodiment 3:

[0046] Please refer to Figure 1 、 Figure 4 and Figure 6 , a fixing block 23 is fixedly connected to the top surface of the base 1. A threaded rod 24 is threadedly connected to the side wall of the fixing block 23. One end of the threaded rod 24 is fixedly connected with a fastening block 25. One side of the fastening block 25 is fixedly connected with a rubber block 26. A through hole 27 is opened on the top surface of the base 1. The top views of the fixing block 23 and the fastening block 25 are both designed as semi-circular. A pedal 28 is fixedly connected to the side of the base 1. The top surface of the pedal 28 is designed as a protrusion. A roller 29 is fixedly installed on the side of the air cylinder 201 through a connecting rod, a fixing frame and a rotating rod.

[0047] Different from Embodiment 2, the setting of the fixing block 23 and the threaded rod 24 can be used to limit and fix the drill pipe 8. By screwing the threaded rod 24, the fastening block 25 is driven to clamp and fix the drill pipe 8, which is convenient for disassembling and replacing the drill pipe 8. And the pedal 28 is arranged on the side of the base 1. When working, the pedal 28 can be stepped on with the foot to conveniently fix the whole device and ensure the stability of the drill pipe 8 during drilling.

[0048] When using the present invention: First, start the motor 4, and then grasp the handle on the receiving plate 3 to drive the receiving plate 3 and the motor 4 to move up and down. At this time, let the drill rod 8 start drilling the soil, and the piston rod 202 will drive the piston block 203 to slide inside the inner wall of the air cylinder 201, so as to inject the inside of the air cylinder 201 into the inside of the water storage cylinder 10 through the air outlet pipe 11, so that the water inside the water storage cylinder 10 can enter the inside of the sleeve 6 from the water inlet pipe 9, and then flow into the soil along the hollow drill rod 8 to moisten the soil to facilitate the drilling of the drill rod 8. When lifting the receiving plate 3 and the motor 4 upward, first remove the rubber plug 14 on the air inlet pipe 12, and then let the piston rod 202 slide upward inside the inner wall of the air cylinder 201, so that the outside air can enter the inside of the air cylinder 201 from the air inlet pipe 12, thus achieving the effect of injecting gas into the inside of the water storage cylinder 10 multiple times. When water injection is not required, the three-way valve 19 can be closed, and the gas discharged from the air cylinder 201 can enter the cavity 20 inside the base 1 and then be discharged from the air outlet hole 22 along the air vent groove 21, so as to blow and dissipate heat on the surface of the drill rod 8, reduce the temperature on the surface of the drill rod 8, and avoid the problem of damage to the drill rod 8 due to high-temperature friction. When the drill rod 8 needs to be disassembled, the threaded rod 24 can be rotated first, so that the fastening block 25 on the threaded rod 24 can fit on the surface of the drill rod 8, thereby fastening the drill rod 8, and then the drill rod 8 can be disassembled and replaced, which further facilitates the use of the device. At the same time, when working, the start of the motor 4 will drive the whole device to shake. In order to avoid the phenomenon of skewed drilling of the drill rod 8, the pedal 28 can be stepped on with the foot to stabilize the whole device, and then the drill rod 8 is stabilized, ensuring the stability of the drilling of the drill rod 8.

[0049] The above are only the embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the scope of the claims of the present invention.
