A drilling device for processing automotive air conditioning pipe joints

Abstract

This invention relates to the field of automotive air conditioning pipe joint processing technology, and more particularly to a drilling device for processing automotive air conditioning pipe joints. The device includes an L-shaped base and two fixing plates fixed to the inner side of the L-shaped base. Electric push rods are symmetrically fixed to the fixing plates. When the electric screw is activated, it rotates forward, causing the frame to move to the left and cover the pipe joint. Simultaneously, the cooperation between the fixing plates and the arc-shaped plate causes the arc-shaped cover plate to swing and close the frame. Then, the electric actuator is activated, causing the drill rod to move to the left to drill a hole in the pipe joint. The frame, arc-shaped cover plate, and elastic cloth block debris from appearing during drilling. The blocked debris is collected and discharged through the lower electric rotating cylinder and corrugated pipe. Activating the air pump allows air to blow the debris inside the pipe joint downwards, thus preventing debris from scattering into the surrounding work area and affecting the environment. Furthermore, it eliminates the need for manual debris removal, ensuring a good working environment and high production efficiency.

Description

Technical Field

[0001] This invention relates to the field of automotive air conditioning pipe joint processing technology, and in particular to a hole-opening device for processing automotive air conditioning pipe joints. Background Technology

[0002] During the processing of automotive air conditioning pipe connectors, holes need to be drilled in order to facilitate the subsequent connection of the pipe connectors to other components. After drilling, the pipe connectors undergo further processing.

[0003] Chinese Patent CN118875789B discloses a drilling device for automotive air conditioning pipe fittings, relating to the field of drilling equipment technology. The device includes a mounting frame with a rotating assembly mounted on top. The rotating assembly comprises three sets of equidistantly arranged discs, with a central shaft at the center of each disc. Multiple limiting posts are equidistantly arranged on the front of each disc, and connector tubes are sleeved around the periphery of each limiting post. The upper two of the three sets of connector tubes are arranged parallel to each other. A drilling component is located in the middle of the three sets of connector tubes on the rotating assembly. While this patent can drill holes in pipe fittings, the drilling force generates debris that easily scatters into the surrounding work area. This not only negatively impacts the working environment but may also pose a safety hazard to workers. Furthermore, some debris falls along the drilled hole onto the inner wall of the pipe. Due to the special structure of the pipe, this debris is often difficult to separate and clean in a timely manner, often requiring manual secondary cleaning. This not only increases the labor intensity of workers but also reduces overall production efficiency.

[0004] The present invention aims to solve the problems existing in the above-mentioned patents. To this end, it proposes a hole-opening device for processing automotive air conditioning pipe joints that can promptly remove and collect debris generated during hole opening, ensuring a good working environment and production efficiency. Summary of the Invention

[0005] To overcome the drawback that generated debris easily scatters into the surrounding work area, which not only adversely affects the working environment and requires manual secondary cleaning, increasing the labor intensity of workers and reducing overall production efficiency, this invention provides a hole-opening device for processing automotive air conditioning pipe joints that can promptly remove and collect debris generated during hole opening, ensuring a good working environment and production efficiency.

[0006] This invention is achieved through the following technical solution:

[0007] A drilling device for processing automotive air conditioning pipe joints includes an L-shaped base and two fixed plates fixed to the inner side of the L-shaped base. Electric push rods are symmetrically fixed to the fixed plates. A mounting bracket is fixed between the ends of the telescopic rods on the same side of the electric push rods. An electric rotating cylinder penetrating the fixed plates is mounted on the mounting bracket. A corrugated pipe is connected to the lower electric rotating cylinder for discharging and collecting debris. The device also includes a drilling assembly, telescopic rods, a frame, an arc-shaped cover plate, a connecting spring, an arc-shaped plate, an elastic cloth, an electric lead screw, a positioning assembly, and a blowing assembly. The positioning assembly is mounted on the electric rotating cylinder for positioning the air conditioning pipe. Telescopic rods are evenly spaced and fixed to the inner side of the L-shaped base. A frame is fixed between the ends of the telescopic rods. Arc-shaped plates are symmetrically rotatably connected to the frame. The system includes an arc-shaped cover plate, with an arc-shaped plate fixed to its shaft and contacting a fixed plate. A connecting spring connects the arc-shaped cover plate to the frame. An elastic cloth is fixedly threaded through the frame. An electric screw threaded to the frame is installed on the L-shaped base. The electric screw drives the frame to move to the left to cover the pipe joint. The frame moves the elastic cloth and the arc-shaped cover plate to the left, and the arc-shaped cover plate moves the arc plate. The fixed plate then drives the arc-shaped cover plate to swing and close the frame. This allows the frame and the arc-shaped cover plate to block and collect the debris ejected during the opening process. The opening assembly is installed between the frame and the elastic cloth for opening the pipe joint. The air blowing assembly is installed between the L-shaped base and the upper electric rotating cylinder for blowing the debris downwards.

[0008] Further explanation: The hole-opening assembly includes a movable frame that is vertically slidably fitted onto the frame body. The movable frame is fixedly connected to an elastic cloth. An electric mounting frame is installed inside the movable frame. A drive motor is installed on the electric mounting frame. An internal hexagonal socket is fixedly connected to the end of the output shaft of the drive motor. A drill rod located inside the frame body is snapped into the internal hexagonal socket. An electric screw that is threadedly connected to the movable frame is installed on the frame body.

[0009] Further explanation: The positioning component includes crossbars that are slidably connected to the inner circumference of the electric rotating cylinder at even intervals. A compression spring is connected between the crossbars and the electric rotating cylinder. A conical frame is vertically slidably connected to the inner side of the electric rotating cylinder. The conical frame contacts the end of the crossbars to drive the crossbars to move inward.

[0010] Further explanation: The air blowing assembly includes a sealing cover fixed to the top circumferential direction of the upper electric rotating cylinder, a hose connected to the sealing cover, an air pump mounted on the L-shaped base, and the air outlet of the air pump connected and communicating with the tail end of the hose.

[0011] Further explanation: The drilling equipment for processing automotive air conditioning pipe joints also includes a switching assembly. The switching assembly includes electric sliding plates symmetrically mounted on an electric mounting frame. A rotating frame is rotatably connected between the electric sliding plates. The drill rod is located inside the rotating frame. A trigger assembly is provided between the electric mounting frame and the rotating frame to drive the rotating frame to rotate. A cylinder is fixedly connected to the frame. An electric rotating shaft is installed in the middle of the cylinder. A magnetic frame is fixed to the end of the electric rotating shaft to magnetically fix different types of drill rods. A rodless cylinder is installed inside the cylinder. An electromagnetic seat is installed on the moving part of the rodless cylinder to drive the drill rod to move for switching.

[0012] Further explanation: The triggering component includes a swing arm fixed to the end of the rotating frame, a guide groove is opened on the inner side of the electric mounting frame, the left side of the guide groove is inclined, a drive frame is rotatably connected to the electric slide plate, one end of the drive frame is located in the guide groove, and a connecting rod is rotatably connected between the other end of the drive frame and the end of the swing arm.

[0013] Further explanation: the drilling equipment for processing automotive air conditioning pipe joints also includes a cleaning component. The cleaning component includes a fixed frame fixed to the inside of the cylinder, and a U-shaped brush vertically slidably connected to the inside of the fixed frame for removing debris attached to the drill rod after use. A discharge frame is connected to the cylinder, and an air outlet pipe is connected to the air outlet end of the air pump. The air outlet pipe is connected to the discharge end of the discharge frame. A drive component is provided between the cylinder and the air outlet pipe for driving the U-shaped brush to move up and down.

[0014] Further explanation: The drive assembly includes a vertical rod fixed to the top of the U-shaped brush, a perforated plate fixed to the end of the vertical rod, a rotating rod rotatably connected to the cylinder, a disc fixed to the end of the rotating rod, a contact rod located inside the perforated plate fixed at an eccentric position on the disc to drive the perforated plate to move up and down, and a rotating blade rotatably connected between the cylinder and the air outlet pipe, the shaft of the rotating blade being connected to the rotating rod via a synchronous belt assembly.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The pipe joint is centered using a crossbar. Then, the electric screw is turned clockwise, moving the frame to the left to cover the pipe joint. Simultaneously, the cooperation between the fixed plate and the arc plate causes the arc cover plate to swing and close the frame. Then, the electric installation is started, moving the drill rod to the left to open the pipe joint. The frame, arc cover plate, and elastic cloth block the debris that appears during the opening. The blocked debris is discharged and collected through the electric rotating drum and corrugated pipe below. The air pump is started, which blows the debris inside the pipe joint downwards to remove it. This prevents debris from being scattered into the surrounding work area and affecting the environment, and eliminates the need for manual debris removal, thus ensuring a good working environment and production efficiency.

[0017] 2. Under the action of the rotating frame and the electromagnetic base, the used drill rod can be driven to disengage from the internal hexagonal socket to complete the switching, so that the required drill rod can be inserted into the internal hexagonal socket. In this way, the operator does not need to manually disassemble and replace different models of drill rods, thereby further improving the overall work efficiency.

[0018] 3. Under the action of the U-shaped brush, whenever the U-shaped brush moves up and down, it can remove the residual debris on the drill rod, which can prevent the residual debris on the drill rod from affecting the subsequent use effect, thereby ensuring the subsequent use effect of the drill rod.

Detailed Implementation

[0031] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, and lateral, also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0032] Example: A drilling device for machining automotive air conditioning pipe joints; please refer to [link / reference]. Figures 1-6As shown, the device includes an L-shaped base 1 and two fixed plates 2 fixed to the right side of the L-shaped base 1. Electric push rods 6 are symmetrically fixed to both the upper and lower fixed plates 2. Mounting brackets 5 are fixed between the ends of the telescopic rods 11 of the electric push rods 6 on both sides. Electric rotating cylinders 3 are installed on the left side of both the upper and lower mounting brackets 5, penetrating the left side of the fixed plate 2. A corrugated pipe 4 is connected to the bottom of the lower electric rotating cylinder 3, allowing debris to be discharged and collected. The device also includes an opening assembly, telescopic rods 11, and a frame 1. 2. An arc-shaped cover plate 13, a connecting spring 14, an arc-shaped plate 15, an elastic cloth 16, an electric lead screw 17, a positioning assembly, and an air blowing assembly. The positioning assembly is installed on the electric rotating cylinder 3. When the positioning assembly operates, it can position the air conditioning pipes. Four telescopic rods 11 are evenly spaced and fixed to the right side of the L-shaped base 1. A frame 12 is fixed between the left ends of the four telescopic rods 11. An arc-shaped cover plate 13 is symmetrically rotatably connected to the left side of the frame 12. The bottom ends of the shafts of the arc-shaped cover plates 13 on both the front and rear sides are fixed. An arc-shaped plate 15 is attached, which contacts the lower fixed plate 2. Connecting springs 14 connect the right sides of the front and rear arc-shaped cover plates 13 to the front and rear sides of the frame 12, respectively. An elastic cloth 16 is fixedly threaded through the right side of the frame 12. An electric screw 17 is installed on the lower right side of the L-shaped base 1, and the electric screw 17 is threaded to the bottom of the frame 12. The electric screw 17 is used to move the frame 12 to the left to cover the pipe joint. The frame 12 moves the elastic cloth 16 and the arc-shaped cover plate 13 to the left. 3 drives the arc plate 15 to move, and the fixed plate 2 drives the arc cover plate 13 to swing through the arc plate 15 to close the frame 12, so that the frame 12 and the arc cover plate 13 can block and collect the debris that is ejected during the opening process. The opening component is installed between the frame 12 and the elastic cloth 16. When the opening component is in operation, the opening component can open the pipe joint. The air blowing component is installed between the L-shaped base 1 and the upper electric rotating cylinder 3. When the air blowing component is in operation, the air blowing component can blow the debris downward.

[0033] Please see Figure 3 and Figure 4 As shown, the hole-opening assembly includes a drill rod 7, a drive motor 71, an internal hexagonal socket 72, a movable frame 8, an electric mounting frame 81, and an electric screw 82. The movable frame 8 is vertically and slidably mounted on the right side of the frame 12. The movable frame 8 is fixedly inserted through the middle of the elastic cloth 16. The electric mounting frame 81 is installed inside the movable frame 8. The drive motor 71 is installed on the middle left side of the electric mounting frame 81. The output shaft end of the drive motor 71 is fixedly connected to the internal hexagonal socket 72. The drill rod 7 is snapped into the inside of the internal hexagonal socket 72. The drill rod 7 is located inside the frame 12. The electric screw 82 is installed on the right rear side of the frame 12. The electric screw 82 is threadedly connected to the right side of the movable frame 8.

[0034] Please see Figure 5As shown, the positioning assembly includes a conical frame 18, a cross rod 181, and a compression spring 182. Six cross rods 181 are slidably connected at even intervals along the circumference on the inner side of the upper and lower electric rotating cylinders 3. A compression spring 182 is connected between the upper part of the cross rod 181 and the inner side of the electric rotating cylinder 3. The conical frame 18 is vertically slidably connected to the inner side of the upper and lower electric rotating cylinders 3. The inner side of the conical frame 18 contacts the end of the cross rod 181. When the conical frame 18 moves, it can drive the cross rod 181 to move inward.

[0035] Please see Figure 6 As shown, the air blowing assembly includes a sealing cover 19, a hose 191 and an air pump 192. The sealing cover 19 is fixedly connected to the top of the upper electric rotating cylinder 3 along the circumference. The hose 191 is connected to the middle of the top of the sealing cover 19. The air pump 192 is installed on the top of the L-shaped base 1. The air outlet of the air pump 192 is connected and communicates with the tail end of the hose 191.

[0036] Initially, the bellows 4 receives the collection container. First, the pipe joint is moved between the upper and lower conical frames 18, aligning the opening position with the drill rod 7. The electric push rod 6 is activated, and the extension rod 11 of the electric push rod 6 extends, causing the upper and lower mounting frames 5 to move closer to each other. The mounting frames 5 then move the upper and lower electric rotating cylinders 3 closer to each other, which in turn move the upper and lower conical frames 18 closer to each other. The conical frames 18 move and contact the pipe joint, squeezing the conical frames 18. This causes the conical frames 18 to move and push the six cross rods 181 closer to each other, compressing the compression spring 182. The cross rods 181 then contact the pipe joint, centering the pipe joint. Position 1, close electric push rod 6, then start electric lead screw 17. Electric lead screw 17 rotates forward, causing frame 12 to move to the left, covering the pipe joint. Frame 12 causes movable frame 8 to move to the left. Movable frame 8 drives drive motor 71 to move to the left via electric mounting frame 81. Drive motor 71 drives drill rod 7 to move to the left via internal hexagonal socket 72. Drill rod 7 moves to the left synchronously with frame 12. At the same time, frame 12 also causes arc-shaped cover plate 13 to move to the left. Arc-shaped cover plate 13 drives arc plate 15 to move to the left. Since arc plate 15 is in contact with the lower fixed plate 2, the lower fixed plate 2 pushes the arc plate 15, which is moving to the left, to swing. The swing of arc plate 15 causes arc cover plate 13 to swing, and connecting spring 14 is stretched. Arc cover plate 13 swings to close frame 12, closing the position. The electric lead screw 17 is activated, followed by the drive motor 71, which rotates the hexagonal socket 72. The rotation of the hexagonal socket 72 then rotates the drill rod 7. The electric mounting frame 81 then slides to the left, driving the drill rod 7 to slide to the left via the drive motor 71 and the hexagonal socket 72. The drill rod 7 moves to the left to drill holes in the pipe joint. The frame 12, the arc-shaped cover 13, and the elastic cloth 16 can block debris ejected during the drilling process. The blocked debris passes through the lower conical frame 18 and falls into the lower electric rotating drum 3. The debris in the lower electric rotating drum 3 falls into the collection container through the corrugated pipe 4, preventing debris from splashing into the surrounding work area and affecting the environment. Furthermore, no manual debris removal is required, thus ensuring a good working environment and production efficiency. Simultaneously, the air pump 192 is activated to... Air is discharged into hose 191, and then into sealing cover 19. Sealing cover 19, via the upper electric rotating cylinder 3, discharges air into the pipe joint. The air blows debris from the opening downwards, which is then discharged into a collection container via the lower electric rotating cylinder 3 and bellows 4. After one hole is drilled in the pipe joint, the electric mounting frame 81 is activated, driving the drill rod 7 to move to the right and reset via the drive motor 71 and the internal hexagonal cylinder 72. Then, the electric screw 82 is activated, rotating the movable frame 8 up and down. The movable frame 8, in turn, moves the electric mounting frame 81 up and down, thus moving the drill rod 7 to the next opening position. The electric screw 82 is then turned off. The above operation can be repeated to continue drilling holes in the pipe joint.When the pipe joint needs to be rotated to drill holes at other locations, the electric rotating drum 3 is started to rotate, driving the conical frame 18 to rotate. The rotation of the conical frame 18 drives the pipe joint to rotate. When the pipe joint rotates so that the next drilling position is on the right, the electric rotating drum 3 is turned off. After the drilling on the pipe joint is completed, the drive motor 71 is turned off, the drill rod 7 stops rotating, and the air pump 192 is turned off. The hose 191 stops venting air into the sealing cover 19. The electric lead screw 17 is started to reverse, driving the frame 12 to move to the right and reset. The frame 12 stops covering the pipe joint. The movement of the frame 12 to the right drives the arc-shaped cover plate 13 to move to the right. The movement of the arc-shaped cover plate 13 to the right drives the arc-shaped cover plate 19 to move to the right. When plate 15 moves to the right, the arc-shaped cover plate 13 swings back to its original position and stops, closing the frame 12, due to the action of the connecting spring 14. The electric screw 17 is then closed, activating the electric push rod 6 to move the upper and lower mounting brackets 5 away from each other. The mounting brackets 5 move the upper and lower electric rotating cylinders 3 away from each other, causing the conical frame 18 to move and disengage from the pipe joint. The conical frame 18 releases the pipe joint, and due to the action of the compression spring 182, the six cross rods 181 move away from each other. The cross rods 181 then slide the upper and lower conical frames 18 back to their original positions, allowing the pipe joint with the hole now opened to be removed.

[0037] Please see Figures 7-9As shown, the drilling equipment for processing automotive air conditioning pipe joints also includes a switching assembly installed between the frame 12 and the movable frame 8. The switching assembly includes an electric sliding plate 20, a rotating frame 201, a cylinder 202, a rodless cylinder 203, an electromagnetic base 204, an electric rotating shaft 205, a magnetic frame 206, and a triggering assembly. Electric sliding plates 20 are symmetrically installed on the electric mounting frame 81. The rotating frame 201 is rotatably connected between the middle left sides of the electric sliding plates 20 on both sides. The drill rod 7 is located inside the rotating frame 201, which allows the drill rod 7 to be placed. A triggering assembly is provided between the electric mounting frame 81 and the rotating frame 201. When the triggering assembly operates, it can drive the rotating frame 201 to rotate. The cylinder 202 is fixedly connected to the top of the frame 12. An electric rotating shaft 205 is installed in the middle of the upper part of the cylinder 202. A magnetic frame 206 is fixed to the bottom of the rotating shaft 205. The magnetic frame 206 can magnetically fix different types of drill rods 7. A rodless cylinder 203 is installed on the left side inside the cylinder 202. An electromagnetic seat 204 is installed on the moving part of the rodless cylinder 203. The electromagnetic seat 204 can drive the drill rod 7 to move for switching. The triggering component includes a swing rod 207, a drive frame 209 and a connecting rod 2010. The swing rod 207 is fixed to both the front and rear ends of the rotating frame 201. Guide grooves 208 are opened on the upper part of both the front and rear sides of the electric mounting frame 81. The left side of the guide groove 208 is inclined. The drive frame 209 is rotatably connected to the upper right side of the electric sliding plates 20 on both the front and rear sides. The upper outer end of the drive frame 209 is located in the guide groove 208. The lower outer end of the drive frame 209 is rotatably connected to the end of the swing rod 207.

[0038] Initially, three drill rods 7 of different models are magnetically attached to the magnetic frame 206. During the removal of the pipe fittings and the drilling of the next batch of different models of pipe fittings, the electric screw 82 is activated, rotating the movable frame 8 to its maximum stroke. This causes the drill rods 7 to move upwards to their maximum stroke. Then, the electric slide plate 20 is activated, causing the rotating frame 201 to move to the left. The rotating frame 201 moves the drill rods 7 to the left, disengaging them from the internal hexagonal socket 72. Simultaneously, the electric slide plate 20 also moves the drive frame 209 to the left. The drive frame 209 slides within the guide groove 208. When the drive frame 209 contacts the inclined position of the guide groove 208, the guide groove 208 drives the drive frame 209 to move to the left. 09. The drive frame 209 rotates forward, causing the connecting rod 2010 to move to the left. The connecting rod 2010 moves to the left, causing the swing rod 207 to swing to the left. The swing rod 207 causes the rotating frame 201 to swing 90 degrees to the left. The rotating frame 201 causes the drill rod 7 to rotate 90 degrees in the opposite direction. The electric slide plate 20 is closed. Then the electromagnetic seat 204 is started. Then the rodless cylinder 203 is started, causing the electromagnetic seat 204 to move downward. When the electromagnetic seat 204 moves downward and contacts the drill rod 7 on the rotating frame 201, the electromagnetic seat 204 attracts the drill rod 7 with magnetic force. Then the rodless cylinder 203 is started, causing the electromagnetic seat 204 to move upward. The upward movement of the electromagnetic seat 204 causes the used drill rod 7 to move upward. The drill rod 7 moves upward and contacts the magnetic frame 206. Upon contact, the magnetic frame 206 attracts and fixes the drill rod 7, while the electromagnetic base 204 continues to move upward, disengaging from the fixed drill rod 7. The rodless cylinder 203 is then closed. Subsequently, the electric rotating shaft 205 is activated, causing the magnetic frame 206 to rotate 90 degrees. The magnetic frame 206 then rotates the drill rod 7, completing the switching. When the desired drill rod 7 rotates to the left, the electric rotating shaft 205 is closed, and the magnetic frame 206 stops rotating the drill rod 7. The rodless cylinder 203 is then activated, causing the electromagnetic base 204 to move downward. When the electromagnetic base 204 moves downward and makes magnetic contact with the desired drill rod 7, it drives the drill rod 7 downward. When the drill rod 7 moves downward and inserts into the rotating frame 201, the electromagnetic base 204 is closed, stopping the movement of the drill rod. 7. The rodless cylinder 203 is activated, causing the electromagnetic base 204 to move upwards and reset. Then, the electric sliding plate 20 is activated to move to the right and reset, causing the rotating frame 201 to move to the right. The rotating frame 201 moves the drill rod 7 to the right, and simultaneously, the electric sliding plate 20 also moves the drive frame 209 to the right. The guide groove 208 causes the drive frame 209 to reverse, and the reverse rotation of the drive frame 209 drives the swing rod 207 to swing to the right via the connecting rod 2010. The swing rod 207, through the rotating frame 201, causes the drill rod 7 to rotate 90 degrees clockwise. The drive frame 209 continues to move to the right and disengages from the inclined position of the guide groove 208. The drill rod 7 continues to move to the right and inserts into the internal hexagonal cylinder 72. The electric sliding plate 20 is then closed, allowing continued drilling of the pipe joint. This eliminates the need for manual disassembly and replacement of different models of drill rod 7, further improving overall work efficiency.

The cleaning assembly includes a fixed frame 21, a U-shaped brush 211, a drive assembly, an air outlet pipe 218, and a discharge frame 219. The fixed frame 21 is fixedly connected to the lower right side of the cylinder 202. The U-shaped brush 211 is vertically slidably connected to the middle of the inner side of the fixed frame 21. When the U-shaped brush 211 moves up and down, it can remove the debris attached to the drill rod 7 after use. The discharge frame 219 is connected to the lower right side of the cylinder 202. The air outlet end of the air pump 192 is connected to the air outlet pipe 218. The rear side of the air outlet pipe 218 is connected to the discharge end of the discharge frame 219. A drive assembly is provided between the cylinder 202 and the air outlet pipe 218. When the drive assembly operates, it can drive the U-shaped brush 211 to move the U-shaped brush 211. The brush 211 moves up and down; the drive assembly includes a vertical rod 212, a perforated plate 213, a rotating rod 214, a disc 215, a contact rod 216, and a rotating blade 217.

The contact rod 216 is fixed to the eccentric position on the left side of the disc 215. The contact rod 216 is located inside the perforated plate 213. When the contact rod 216 rotates, it can drive the perforated plate 213 to move up and down. The rotating blade 217 is rotatably connected between the lower right side of the cylinder 202 and the left side of the air outlet pipe 218. The shaft of the rotating blade 217 is connected to the right side of the rotating rod 214 through a synchronous belt assembly.

[0040] When the air pump 192 starts, it also discharges air into the air outlet pipe 218. The airflow in the air outlet pipe 218, through the discharge frame 219, creates a negative pressure state inside the fixed frame 21. Simultaneously, the airflow in the air outlet pipe 218 drives the rotating blade 217 to rotate. The rotation of the rotating blade 217, via the synchronous belt assembly, drives the rotating rod 214 to rotate. The rotating rod 214 drives the disc 215 to rotate, which in turn drives the contact rod 216 to rotate. The contact rod 216 drives the straight perforated plate 213 to move up and down, which in turn drives the vertical rod 212 to move up and down. The vertical rod 212 then drives the U-shaped brush 211 to move up and down. When the used drill rod 7 rotates to contact the U-shaped brush 211, the U-shaped brush... The brush 211 moves up and down to remove residual debris from the drill rod 7. The removed debris falls into the fixed frame 21, and under negative pressure, it is discharged into the discharge frame 219. The debris in the discharge frame 219 is then discharged into the air outlet pipe 218, which discharges the debris. When the air pump 192 is turned off, air stops being discharged into the air outlet pipe 218, and the rotating blade 217 stops rotating. The rotating blade 217 stops driving the rotating rod 214 to rotate, and the rotating rod 214 stops driving the disc 215 to rotate. The disc 215 stops driving the straight perforated plate 213 to move up and down via the contact rod 216, and the straight perforated plate 213 stops driving the U-shaped brush 211 to move up and down via the vertical rod 212. This prevents residual debris on the drill rod 7 from affecting its subsequent use, thus ensuring the effectiveness of the drill rod 7 in subsequent applications.
