[0002] Municipal roads refer to roads that connect various areas within a city and link with roads outside the city. During the construction of municipal roads, drilling is often required. A search revealed a patent with application number 202223073973.7, which discloses a directional drilling device for municipal road construction. This device falls under the technical field of municipal road construction and addresses the problem of inaccurate control of the drilling depth when using directional drilling devices. The device includes a drilling frame, a support plate, and a drilling mechanism. The drilling frame is equipped with a drive mechanism and a control mechanism. The drive mechanism includes a lifting groove, a drive screw, and a drive sleeve. A worm gear is horizontally rotatably mounted between the inner walls of both sides of the control chamber.

[0003] However, in actual use, the applicant found that it could not reduce dust during the drilling process, and the drilling device required personnel to move it, which was not convenient or labor-saving. Therefore, we propose a directional drilling device for municipal road construction. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a directional drilling device for municipal road construction, comprising a drilling frame, a lifting seat slidably connected to the inner wall of the drilling frame, a motor fixedly mounted in the middle of the lifting seat, a drill rod coaxially fixedly connected to the output end of the motor, an annular nozzle fixedly connected to the bottom of the motor, and nozzles evenly arranged at the bottom of the annular nozzle, a water tank and a first hydraulic cylinder fixedly connected to the top of the drilling frame, the lower end of the first hydraulic cylinder movably penetrating through the top of the drilling frame and fixedly connected to the lifting seat, and a water pump fixedly mounted on one side of the drilling frame. The water pump's inlet is connected to the bottom of the water tank via an inlet hose, and the water pump's outlet is connected to the inside of the annular nozzle via an outlet hose. The drilling frame has symmetrical through slots on both sides and symmetrical storage slots on the bottom. A second hydraulic cylinder is fixedly installed at the bottom of the through slot, and the lower end of the second hydraulic cylinder extends into the storage slot and is fixedly connected to a mounting base.

[0020] Please see Figure 1-3 As shown, this utility model provides a technical solution:

[0021] A directional drilling device for municipal road construction includes a drilling frame 1. A lifting seat 2 is slidably connected to the inner wall of the drilling frame 1. Guide sliders are symmetrically arranged on both sides of the lifting seat 2, and the guide sliders slide along guide grooves opened on the inner side wall of the drilling frame 1. A motor 8 is fixedly installed in the middle of the lifting seat 2. A drill rod 9 is coaxially fixedly connected to the output end of the motor 8. An annular nozzle 10 is fixedly connected to the bottom of the motor 8, and nozzles 102 are evenly arranged at the bottom of the annular nozzle 10. The annular nozzle 10 is sleeved on the outside of the drill rod 9. The annular nozzle 10 is fixed to the bottom of the lifting seat 2 by symmetrically arranged support feet 101 at its top. A water tank 6 and a first hydraulic cylinder 7 are fixedly connected to the top. A clearance groove for the first hydraulic cylinder 7 is provided in the middle of the water tank 6. The lower end of the first hydraulic cylinder 7 movably passes through the top of the drilling frame 1 and is fixedly connected to the lifting seat 2. A water pump 4 is fixedly installed on one side of the drilling frame 1. The inlet of the water pump 4 is connected to the bottom inside of the water tank 6 via an inlet hose 5, and the outlet of the water pump 4 is connected to the inside of the annular nozzle 10 via an outlet hose 3. By driving the water pump 4 to rotate, water from inside the water tank 6 is transported to the annular nozzle 10 through the inlet hose 5 and the outlet hose 3, and then sprayed out through the nozzle 102. This allows water to be pumped out during the drilling process of the drill rod 9 into the ground. This system achieves dust suppression through water spraying, with some water sprayed onto the drill rod 9 and flowing downwards along its outer wall, providing some water cooling and thus extending its service life. A controller 11 is fixedly mounted on the outer wall of the drilling frame 1, and a battery 12 is fixedly connected to the outer wall of the drilling frame 1 below the controller 11. The controller 11 is electrically connected to the battery 12 via wires. The water pump 4, the first hydraulic cylinder 7, and the motor 8 are also electrically connected to the controller 11 via wires. In use, moving the drilling frame 1 moves the drill rod 9 to the drilling position, and then the controller 11 drives the motor 8 to rotate the drill rod 9. Simultaneously, the controller 11 drives the first hydraulic cylinder 7 to move the lifting seat 2 downward. The downward movement of the lifting seat 2 can drive the motor 8 and the drill rod 9 to move downward together. At this time, the drill rod 9 can drill a hole in the ground. While drilling, the controller 11 can drive the water pump 4 to rotate. The rotation of the water pump 4 can transport the water in the water tank 6 to the annular spray pipe 10 through the water inlet hose 5 and the water outlet hose 3, and spray it out through the nozzle 102. During the drilling process of the drill rod 9, water spraying can be used to reduce dust, and some water sprayed on the drill rod 9 can flow down along the outer wall of the drill rod 9 to provide a certain water cooling effect.

[0022] The drilling frame 1 has symmetrical through slots 13 on both sides and symmetrical storage slots on the bottom. A second hydraulic cylinder 14 is fixedly mounted at the bottom of each through slot 13. The two second hydraulic cylinders 14 are electrically connected to a controller 11 via wires. The lower end of each second hydraulic cylinder 14 extends into the storage slot and is fixedly connected to a mounting base 15. The outer wall of the mounting base 15 slides along the inner wall of the storage slot. Traveling wheels 16 are symmetrically fixedly mounted at the bottom of the mounting base 15. A pusher 17 is fixedly connected to the other side of the drilling frame 1. By driving the second hydraulic cylinders 14, the mounting base 15 moves upward, which in turn moves the traveling wheels 16 into the storage slot, allowing the bottom of the drilling frame 1 to contact the ground. This makes the device more stable during drilling. After drilling is completed, the device can be further stabilized by... The second hydraulic cylinder 14 drives the mounting base 15 downward, which in turn drives the traveling wheels 16 to contact the ground and lifts the drilling frame 1 off the ground. By pushing the pusher 17, the drilling device can be moved quickly in conjunction with the traveling wheels 16, making it more convenient and labor-saving. After the device is moved to the drilling position, the controller 11 drives the second hydraulic cylinder 14 to drive the mounting base 15 upward, which in turn drives the traveling wheels 16 to move into the storage slot, so that the bottom of the drilling frame 1 makes stable contact with the ground. After drilling is completed, the second hydraulic cylinder 14 drives the mounting base 15 downward, which in turn drives the traveling wheels 16 to contact the ground and lifts the drilling frame 1 off the ground. At this time, the drilling device can be moved quickly in conjunction with the pusher 17 and the traveling wheels 16.

[0023] Working principle: In use, the movable drilling frame 1 moves the drill rod 9 to the drilling position. After the device is moved to the drilling position, the controller 11 drives the second hydraulic cylinder 14 to move the mounting base 15 upward, which in turn moves the traveling wheels 16 into the storage slot, making the bottom of the drilling frame 1 make stable contact with the ground. Then, the controller 11 drives the motor 8 to rotate the drill rod 9. At the same time, the controller 11 drives the first hydraulic cylinder 7 to move the lifting seat 2 downward. The downward movement of the lifting seat 2 can drive the motor 8 and the drill rod 9 to move downward together. At this time, the drill rod 9 can drill a hole in the ground. While drilling, the controller 11 can control the rotation of the drill rod 9. The controller 11 drives the water pump 4 to rotate. The rotation of the water pump 4 can transport the water inside the water tank 6 to the annular nozzle 10 through the inlet hose 5 and the outlet hose 3, and spray it out through the nozzle 102. This can achieve water spraying to reduce dust during the drilling process of the drill rod 9 to the ground. Some of the water sprayed on the drill rod 9 flows down along the outer wall of the drill rod 9, which can cool the drill rod 9 to a certain extent. After drilling is completed, the second hydraulic cylinder 14 drives the mounting base 15 to move downward, which can drive the traveling wheel 16 to contact the ground and make the drilling frame 1 lift off the ground. At this time, the drilling device can be moved quickly by pushing the pusher 17 in conjunction with the traveling wheel 16.
