[0002] In building construction, wall drilling is a crucial step in the installation of pipelines and the fixing of components. Traditional wall drilling equipment typically consists of a drilling machine body, a drill bit, and a rotating head. The rotating head drives the drill bit to rotate and break up the wall to complete the drilling.

[0003] However, existing technologies have the following prominent problems: First, the dust generated during drilling is easily dispersed into the air, polluting the construction environment and potentially harming the respiratory health of operators; second, the drilling rig itself lacks effective positioning assistance during operation, making it prone to hole displacement due to human error, affecting subsequent construction accuracy; third, traditional devices lack operational stability, and prolonged operation can easily lead to worker fatigue, further exacerbating the risk of hole deviation. These problems urgently need to be addressed through structural optimization. Utility Model Content

The telescopic dust suction hood 4 includes a fixed frame 5 connected to the drilling machine body 1, a sealing frame 7 slidably connected to the fixed frame 5 through multiple guide rods 6, and a telescopic cover 8 connecting the fixed frame 5 and the sealing frame 7.

[0028] In this utility model, the fixing frame 5 has a fixing ring 17 in the middle that is connected to the drilling rig body 1. A positioning plate 18 is slidably connected to one side of the fixing ring 17. The width of the positioning plate 18 matches the diameter of the fixing ring 17. The two sides of the positioning plate 18 are fixedly connected to the fixing frame 5 by bolts 19. The two sides of the positioning plate 18 are provided with wing plates for guiding and limiting. The connection between the bolts 19 and the positioning plate 18 and the fixing frame 5 is located on the wing plates. The inner circumferential side of the fixing ring 17 and the positioning plate 18 is provided with grooves 20 for increasing friction.

[0029] In this utility model, the guide rod 6 is located at the four corners of the sealing frame 7 and the fixed frame 5. One end of the guide rod 6 is fixedly connected to the sealing frame 7, and the rod body of the guide rod 6 is slidably connected to the fixed frame 5. A compression spring 13 is sleeved on the outside of the guide rod 6 between the fixed frame 5 and the sealing frame 7 to ensure that the front end of the dust collection hood can always automatically stick to the wall during the drilling process. One of the guide rods 6 has an marking scale 14 engraved on its upper part to indicate the moving distance, which can intuitively determine the moving distance of the drill bit 2 during the drilling process.

[0030] In this utility model, the telescopic cover 8 adopts a corrugated tubular structure or a nested sliding sleeve structure, and the front end of the telescopic cover 8 is fixedly connected to the sealing frame 7 by threads, and the rear end of the telescopic cover 8 is fixedly connected to the fixed frame 5 by an extended sealing platform 15. The front end of the connection between the telescopic cover 8 and the sealing frame 7 is provided with a flexible sealing ring 16 that fits against the wall surface when drilling; the middle of the sealing frame 7 is provided with a dust suction port 9.

[0031] In this utility model, a negative pressure dust suction channel 10 is provided on one side of the sealing frame 7 inside the telescopic cover 8. The inner side of the negative pressure dust suction channel 10 is connected to the inside of the telescopic cover 8, and the other end is provided with a quick interface 11 for connecting to an external dust suction device.

[0032] In this utility model, an auxiliary handle 12 is provided on one side of the fixing frame 5. The auxiliary handle 12 extends perpendicularly to the side of the fixing frame 5, and the auxiliary handle 12 is one of a single straight rod or an L-shaped bent rod structure.

[0033] Working principle

[0034] 1. Dust collection module: When drilling, the dust generated by the drill bit 2 breaking the wall flows towards the telescopic cover 8 with the airflow. Since the flexible sealing ring 16 at the front end of the telescopic cover 8 forms a closed space with the wall, the dust is confined inside the telescopic cover 8. The external dust collection equipment draws air into the negative pressure dust collection channel 10 through the quick interface 11, so that a negative pressure environment is formed inside the telescopic cover 8. The dust is sucked into the telescopic cover 8 through the dust collection port 9, and finally enters the external equipment for collection through the negative pressure dust collection channel 10, realizing real-time control of dust.

[0035] 2. Positioning Module: The sliding connection structure between the fixing ring 17 and the positioning plate 18 allows for adjustment of the installation position along the circumference of the drill body 1, facilitating use; after the bolts 19 are fixed, the groove 20 on the inner side of the positioning plate 18 and the fixing ring 17 increases the friction, preventing the drill body 1 from sliding during drilling, ensuring hole position accuracy, and the distance the drill bit 2 moves forward during drilling can be intuitively determined by the marking scale 14 on the guide rod 6.

[0036] 3. Operation assistance module: The structure of the auxiliary grip 12 extending vertically to the fixed frame 5 provides an ergonomic grip position and reduces operation fatigue; the compression spring 13 forms a buffer between the sealing frame 7 and the fixed frame 5, ensuring that the front end of the dust hood can always automatically stick to the wall during drilling. When the drill bit 2 moves forward, the dust hood is compressed by the wall. When the drilling is completed and the drill bit retracts, the spring pushes it back to its original position to maintain the sealing of the telescopic cover 8.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
