During operation, the drill bit rod to be processed is installed and fixed inside the drill bit stabilizing hole 13, and the first motor 12 is started, causing the second motor 15 to be fixedly connected to the stabilizing plate 13. The output of motor 12 drives the drill bit stabilizing hole 13 to rotate, which in turn drives the drill rod to be processed to rotate. The second motor 15 is started, which drives the grinding stone 14 to rotate through the connecting arm 16. The position of the connecting arm 16 is adjusted so that the grinding stone 14 is close to the drill rod. The rotation of the grinding stone 14, in conjunction with the rotation of the drill bit stabilizing hole 13, grinds the drill rod. Through the above structure, the drill rod to be processed is processed by rotary grinding. The adjustable robotic arm allows the device to grind drill rods of different sizes, improving the practicality of the device.

[0025] like Figures 1 to 3 As shown, a stabilizing frame 21 is fixed to the top of the bearing plate 1. A third motor 23 is fixed to the side wall of the stabilizing frame 21. The output end of the side wall of the third motor 23 is rotatably connected to a rotating shaft 22. There are two rotating shafts 22, which are installed through the side wall of the rotating shaft 22. The bottom plate 2 is slidably connected inside the stabilizing frame 21. The rotating shaft 22 passes through the bottom plate 2. The outer wall of the rotating shaft 22 and the bottom plate 2 are connected with the same thread. A second motor 15 is fixed to the top of the bottom plate 2. When working, the third motor 23 is started, so that the output end of the third motor 23 drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the bottom plate 2 to move through the thread on the outer wall, which in turn drives the second motor 15 to move. The second motor 15 drives the connecting arm 16 to move, and the connecting arm 16 drives the grinding stone 14 to move. By adjusting the position of the grinding stone 14, it is used to grind drill rods of different sizes. Through the above structure, the device is adjusted using simple moving components, so that the device can grind drill rods of different sizes. At the same time, the open structure makes the daily maintenance of the device convenient and fast, increasing the practicality of the device.

[0026] like Figures 1 to 2As shown, a water pump 31 is fixedly connected to the side of the bearing plate 1. A water supply pipe 3 is rotatably connected to the top of the water pump 31.

During operation, the water pump 31 is started, which transmits water through the water supply pipe 3 to the nozzle 32. The nozzle 32 sprays water between the grinding stone 14 and the drill rod. The introduction of water reduces the problem of metal chips splashing during the grinding process. Through the above structure, the addition of liquid for grinding reduces the splashing of metal chips during the grinding process, ensuring the hygiene of the processing environment and increasing the practicality of the device.

[0027] like Figures 1 to 2 As shown, a storage tank 4 is fixedly connected to the side wall of the support plate 1. A water inlet is opened on the side of the storage tank 4 and a water pump 31 is fixedly connected thereto. A drain hole is opened at the bottom of the storage tank 4. During operation, water is sprayed between the grinding stone 14 and the drill rod through the nozzle 32. The water carries the debris into the storage tank 4. At the same time, the water pump 31 transmits the water back to the nozzle 32 through the water inlet on the side wall of the storage tank 4, realizing the recycling of water. The water is discharged by opening the drain hole at the bottom of the storage tank 4. Through the above structure, the addition of a water storage tank enables the device to circulate water, reducing the water consumption of the device, reducing processing costs, and increasing the practicality of the device.

[0028] like Figures 1 to 4 As shown, a filter basket 5 is installed inside the storage tank 4. The filter basket 5 is made of high-density filter screen. During operation, the filter basket 5 separates water from metal debris, reducing the problem of water pump 31 transmitting metal debris to nozzle 32 and causing blockage during water delivery. Through the above structure, the device is equipped with a filtration function, making the water circulation more stable. At the same time, the processed debris is collected, increasing the practicality of the device.

[0029] like Figures 1 to 4 As shown, a handle 6 is fixed to the top of the filter basket 5. There are two handles 6, which are located at both ends of the top of the filter basket 5.

Through the above structure, the metal debris generated by the device can be processed quickly, increasing the practicality of the device.

[0030] like Figures 1 to 2 As shown, the support plate 1 and the storage pool 4 are fixedly connected to the bottom of the support rods 7. There are four support rods 7, which are located at the four corners of the bottom of the device. During operation, the support rods 7 provide good support for the device, so that the device remains stable during the downward movement, reducing the problem of reduced processing quality caused by vibration. Through the above structure, the device remains stable during operation, reduces vibration during operation, and increases the processing quality of the device.

[0031] During operation, the drill rod to be processed is installed and fixed inside the drill bit stabilizing hole 13. The first motor 12 is started, causing its output to rotate the drill bit stabilizing hole 13, which in turn rotates the drill rod. The second motor 15 is started, causing it to rotate the grinding stone 14 via the connecting arm 16. The position of the connecting arm 16 is adjusted so that the grinding stone 14 is close to the drill rod. The rotation of the grinding stone 14, in conjunction with the rotation of the drill bit stabilizing hole 13, grinds the drill rod. The third motor 23 is started, causing its output to rotate the rotating shaft 22. The rotating shaft 22, through the threads on its outer wall, moves the base plate 2, which in turn moves the second motor 15. The second motor 15 then moves the connecting arm 16, which in turn moves the grinding stone 14. The position of the grinding stone 14 is adjusted to grind drill rods of different sizes. The water pump 31 is started, causing it to pump water... Water is delivered to nozzle 32 via water pipe 3. Nozzle 32 sprays water between grinding stone 14 and drill rod, reducing the problem of metal shavings splashing during the grinding process. Water sprayed between grinding stone 14 and drill rod by nozzle 32 carries the shavings into storage tank 4. At the same time, water pump 31 delivers water back to nozzle 32 through water inlet on the side wall of storage tank 4, realizing water recycling. Water is drained by opening the drain hole at the bottom of storage tank 4. Water and metal shavings are separated by filter basket 5, reducing the problem of water pump 31 delivering metal shavings into nozzle 32 and causing blockage. By lifting handle 6, the filter basket 5 is moved upward, allowing the filtered metal shavings inside the filter basket 5 to be quickly cleaned. Support rod 7 provides good support for the device, keeping the device stable during downward movement and reducing the problem of reduced processing quality caused by vibration.
