DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention. Example 1

[0020] like Figure 1-Figure 5 As shown, a drill bit cleaning device in an embodiment of the first aspect of the present invention includes an outer frame 11, a hydraulic rod 12 is fixedly installed on the upper part of the outer frame 11, a cleaning cabin 21 is fixedly installed on the lower part of the outer frame 11, a rotary joint 13 is rotatably installed at the lower end of the hydraulic rod 12, a plurality of clips 14 are installed on the bottom surface of the rotary joint 13, and the clips 14 can clamp the spiral drill bit, and a partition 23 is provided in the middle of the cleaning cabin 21, and the partition 23 divides the inner wall of the cleaning cabin 21 into two parts, upper and lower parts, a plurality of hot air nozzles 27 are installed on the inner wall of the cleaning cabin 21 above the partition 23, and a plurality of cold water nozzles 28 are installed on the inner wall of the cleaning cabin 21 below the partition 23, and a groove rod 26 is installed on the inner wall of the cleaning cabin 21 below the partition 23, and the groove rod 26 can extend into the thread groove on the surface of the spiral drill bit at one end away from the inner wall of the cleaning cabin 21.

[0021] In the above embodiment, it should be noted that the clips 14 are made of rubber material and have a certain elasticity that can clamp the spiral drill bit. The spiral drill bit to be cleaned is inserted between the clips 14, and the spiral drill bit is pushed into the cleaning chamber 21 by starting the hydraulic rod 12. When the spiral drill bit passes through the upper layer of the cleaning chamber 21, the hot air nozzle 27 blows away the dust on the surface of the drill bit and heats the spiral drill bit. Then the spiral drill bit enters the lower layer of the cleaning chamber 21. The cold water nozzle 28 in the lower layer of the cleaning chamber 21 continuously rinses the drill bit surface and quickly cools the spiral drill bit. Based on the principle of thermal expansion and contraction, the hard foreign matter in the groove on the surface of the spiral drill bit is loosened or falls off due to the temperature difference. When the spiral drill bit is squeezed by the groove rod 26, the rotary joint 13 drives the spiral drill bit to rotate, so that the groove rod 26 removes all the hard foreign matter along the trajectory of the groove on the surface of the spiral drill bit, so as to achieve the effect of thoroughly cleaning the hard foreign matter stuck in the thread groove on the surface of the spiral drill bit, improving the cutting efficiency of the drill bit after cleaning, avoiding mechanical damage or deformation of the drill bit, and extending its service life. Example 2

[0022] like Figure 2-Figure 4As shown, a drill bit cleaning device includes all the contents of Example 1. In addition, the cleaning cabin 21 is arranged directly below the hydraulic rod 12, and a top cover 22 is installed on the top surface of the cleaning cabin 21. An opening is provided in the center of the top cover 22. The central opening on the top surface of the top cover 22 is a trumpet-shaped structure that expands outward. A drain port 24 is provided at the bottom of the cleaning cabin 21, an opening is provided in the middle of the partition 23, and the top surface of the partition 23 is a funnel-shaped structure.

[0023] In the above embodiment, it should be noted that the water sprayed from the cold water nozzle 28 will wash the surface of the drill bit and then carry away the mud, sand and dirt and be discharged from the drain outlet 24. The interior of the partition 23 is filled with heat-insulating material to prevent the temperature of the upper part of the cleaning chamber 21 from being transferred to the lower part. Example 3

[0024] like Figure 2-Figure 4 As shown, a drill bit cleaning device includes all the contents of Example 2. In addition, a plurality of brush plates 25 are installed on the inner wall of the cleaning cabin 21 above the partition 23, and the plurality of brush plates 25 are arranged around the inner wall of the cleaning cabin 21 above the partition 23. A hot air duct 15 is provided in the middle of one side of the cleaning cabin 21, one end of the hot air duct 15 is connected to the hot air blower, and the other end of the hot air duct 15 is annularly structured and sleeved on the outer wall of the cleaning cabin 21. A plurality of hot air risers 17 are installed on the top surface of one annular end of the hot air duct 15, and a plurality of hot air nozzles 27 are fixedly installed on the side of the hot air riser 17 close to the cleaning cabin 21, and the hot air nozzles 27 pass through the cleaning cabin 21 to the inner wall of the cleaning cabin 21.

[0025] In the above embodiment, it should be noted that the brush plate 25 has the function of brushing the dust on the surface of the spiral drill bit, and the high temperature heat is introduced into the hot air riser 17 through the hot air duct 15 and ejected from the hot air nozzle 27 to achieve the effect of blowing away the dust on the drill bit surface and heating the spiral drill bit. Example 4

[0026] like Figure 2-Figure 4 As shown, a drill bit cleaning device includes all the contents of Example 3. In addition, several grooved rods 26 are installed around the inner wall of the cleaning cabin 21 below the partition 23. The grooved rods 26 are spirally arranged along the trajectory of the thread groove on the surface of the spiral drill bit. A cold water pipe 16 is provided at the lower part of one side of the cleaning cabin 21. One end of the cold water pipe 16 is connected to the liquid cooler, and the other end of the cold water pipe 16 is annular and sleeved on the outer wall of the cleaning cabin 21. Several cold water risers 18 are installed on the top surface of one end of the ring of the cold water pipe 16. Several cold water nozzles 28 are fixedly installed on the side of the cold water riser 18 close to the cleaning cabin 21. The cold water nozzles 28 pass through the cleaning cabin 21 to the inner wall of the cleaning cabin 21.

Then the spiral drill bit enters the lower layer of the cleaning chamber 21, and the cold water duct 16 draws cold water. Cold water is introduced into the vertical pipe 18 and sprayed from the cold water nozzle 28 to rinse the drill bit surface and quickly cool the spiral drill bit. The hard foreign matter in the groove on the surface of the spiral drill bit is loosened or falls off due to the temperature difference. Finally, when the spiral drill bit is squeezed by the groove rod 26, the spiral drill bit is driven to rotate by the rotary joint 13, so that the groove rod 26 removes all the hard foreign matter along the trajectory of the groove on the surface of the spiral drill bit. The water sprayed from the cold water nozzle 28 rinses the drill bit surface and then carries away the mud, sand and dirt and is discharged from the drain port 24 to complete the cleaning of the drill bit.
