Technical Field

[0001] This application relates to the field of handheld drilling rig technology, specifically a dust collection device for a pneumatic handheld drilling rig. Background Technology

[0002] A pneumatic handheld drill is a portable tool that uses compressed air as a power source and drives the drill bit through a pneumatic transmission system to perform drilling operations. It features high efficiency, convenience, and safety, and is widely used in construction, decoration, furniture manufacturing, stone processing, and other fields. It employs a high-quality air compressor to provide stable and powerful power output, ensuring efficient drilling operations. The handheld design allows operators to easily carry and move the drill, adapting to drilling needs in various complex environments.

[0003] During the drilling process, when the drill bit rotates and comes into contact with the wall, it generates a large amount of particulate dust that diffuses into the environment. The dust in the air can affect people's vision, and breathing in the dust can cause people to cough. Utility Model Content

[0004] The purpose of this application is to provide a dust collection device for a pneumatic handheld drilling rig, in order to solve the problems mentioned in the background art, such as dust in the air affecting the visibility of personnel and causing personnel to cough when breathing in the dust.

[0005] To achieve the above objectives, this application provides the following technical solution: a dust collection device for a pneumatic handheld drill, comprising: a handheld drill body, a collection component, a pushing component, and a positioning component. The handheld drill body consists of a drill body and a drill bit disposed on the output end of the drill body. The collection component is disposed outside the output end of the drill body. The collection component includes a first annular block fixed outside the output end of the drill body, a corrugated folded pipe with one end disposed on the first annular block, a second annular block disposed at the other end of the corrugated folded pipe, a discharge port opened at the bottom of the second annular block, a connecting pipe with one end disposed on the outer wall of the second annular block, the connecting pipe being disposed at the discharge port of the second annular block, a collection box disposed at the other end of the connecting pipe, and a vibration motor fixed on the outer wall of the second annular block. The pushing component is disposed on both sides of the outer wall of the second annular block, and the positioning component is disposed on the top of the outer wall of the second annular block.

[0006] By adopting the above technical solution, the generated dust can be shielded and collected quickly.

[0007] Preferably, the pushing assembly includes a first block welded to both sides of the outer wall of the second annular block and a second block fixed to both sides of the outer wall of the drilling rig body.

[0008] By adopting the above technical solution, Block 1 and Block 2 can serve as a connection between the structures.

[0009] Preferably, the first block and the second block are integrally formed with a connecting shaft.

[0010] By adopting the above technical solution, the connecting shaft between block one and block two can provide the structure on the shaft to achieve angular changes.

[0011] Preferably, the pushing assembly further includes a first rod rotatably connected at one end to the first block connecting shaft, a second rod rotatably connected at one end to the second block connecting shaft, and a rotating shaft passing through the other ends of the first rod and the second rod.

[0012] By adopting the above technical solution, poles No. 1 and No. 2 can change their angles through the pivot.

[0013] Preferably, the pushing assembly further includes springs whose two ends are respectively mounted on the outer walls of rod number one and rod number two via metal hooks.

[0014] By adopting the above technical solution, the spring can lift rod number one and rod number two to change their angle through the pivot.

[0015] Preferably, the positioning component includes a third block welded to the top of the second annular block and a fourth block welded to the top of the first annular block. A connecting shaft is integrally formed inside the third and fourth blocks, and a hook is rotatably connected to the connecting shaft of the third block at one end.

[0016] By adopting the above technical solution, the hook can be hooked onto block number four by displacement.

[0017] In summary, this application includes at least one of the following beneficial effects:

[0018] By incorporating a collection component and a pushing component, the pushing component allows the collection component to adhere to the wall surface as the drill bit rotates and penetrates deeper into the cavity. This provides the collection component with complete coverage of the drill bit, preventing dust from spreading from inside the collection component. Furthermore, the vibration of the vibrating motor shakes the dust accumulated at the edge of the second annular block into the collection box for storage, effectively achieving complete dust collection and preventing any impact on personnel.

[0019] By incorporating a collection component and a positioning component, when the drill bit needs to be replaced, the positioning component can drive the collection component to retract, preventing the collection component from completely obstructing the drill bit and providing personnel with a complete view for drill bit replacement.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] The following is in conjunction with the appendix Figure 1-3 The embodiments of this application will be described in further detail. Example

[0026] Please see Figures 1-3 This embodiment provides a technical solution: a dust collection device for a pneumatic handheld drill, comprising: a drill body 1, a drill bit 2, a collection component 3, a pushing component 4, and a positioning component 5;

[0027] The handheld drilling rig consists of a drilling rig body 1 and a drill bit 2 set on the output end of the drilling rig body 1. The above is the existing technology and will not be described in detail below.

[0028] The collecting component 3 is located outside the output end of the drilling rig body 1. The collecting component 3 includes a first annular block 301 fixed outside the output end of the drilling rig body 1, a corrugated folded pipe 302 with one end set on the first annular block 301, a second annular block 303 set at the other end of the corrugated folded pipe 302, a discharge port 304 opened at the bottom of the second annular block 303, a connecting pipe 305 with one end set on the outer wall of the second annular block 303, the connecting pipe 305 set at the discharge port 304 of the second annular block 303, a collecting box 306 set at the other end of the connecting pipe 305, and a vibration motor 307 fixed on the outer wall of the second annular block 303. The pushing component 4 is set on both sides of the outer wall of the second annular block 303, and the positioning component 5 is set on the top of the outer wall of the second annular block 303.

[0029] The drill bit 2 is fixed on the output end of the drill body 1. When the drill bit 2 is attached to the wall for drilling, the collection component 3 can be attached to the wall by pushing the component 4. The collection component 3 can cover and collect the dust generated by the rotation of the drill bit 2. When the drill bit 2 needs to be replaced, the collection component 3 can be folded and stored by the positioning component 5, so that the collection component 3 no longer covers the drill bit 2.

[0030] The first annular block 301 and the second annular block 303 are connected by a corrugated folding tube 302, which enables folding and storage and extension. The second annular block 303 can be attached to the wall by pushing the component 4. At this time, the second annular block 303 can discharge the generated dust through the discharge port 304. The dust moves to the inside of the collection box 306 through the connecting tube 305 on the discharge port 304. When dust accumulates at the discharge port 304, the vibration motor 307 is started. The vibration generated by the vibration motor 307 circulates the accumulated dust. Example

[0031] Please see Figures 1-3 This embodiment provides a technical solution: a dust collection device for a pneumatic handheld drill, comprising: a first block 401, a second block 402, a first rod 403, a second rod 404, a rotating shaft 405, and a spring 406;

[0032] The pushing component 4 includes a first block 401 welded to both sides of the outer wall of the second annular block 303 and a second block 402 fixed to both sides of the outer wall of the drilling rig body 1. The first block 401 and the second block 402 have an integrally formed connecting shaft inside. One end of the first rod 403 is rotatably connected to the connecting shaft of the first block 401, and the other end of the second rod 404 is rotatably connected to the connecting shaft of the second block 402. A rotating shaft 405 is installed through the other end of the first rod 403 and the second rod 404. Springs 406 are respectively installed on the outer walls of the first rod 403 and the second rod 404 by metal hooks at both ends.

[0033] The first rod 403 and the second rod 404 can change their angles through the pivot 405. The first rod 403 and the second rod 404 can also change their angles within the first block 401 and the second block 402. At this time, the second ring block 303 can be moved and attached to the wall by the elastic force of the spring 406. Example

[0034] Please see Figures 1-3 This embodiment provides a technical solution: a dust collection device for a pneumatic handheld drill, comprising: block 501, hook 502 and block 503;

[0035] The positioning component 5 includes a third block 501 welded to the top of the second annular block 303, and a fourth block 503 welded to the top of the first annular block 301. A connecting shaft is integrally formed inside the third block 501 and the fourth block 503, and a hook 502 is rotatably connected to the connecting shaft of the third block 501 at one end.

[0036] When the drill bit 2 on the drill body 1 needs to be replaced, the hook 502 on the third block 501 is pulled, which can drive the folding of the corrugated folded pipe 302 and the displacement of the second annular block 303. When the hook 502 is hooked on the fourth block 503 of the first annular block 301, the stability of the first annular block 301, the corrugated folded pipe 302 and the second annular block 303 when folded and connected can be ensured.

[0037] The implementation principle of the dust collection device for a pneumatic handheld drill rig in this application is as follows:

[0038] First, the drill bit 2 is fixed on the output end of the drill body 1. When the drill bit 2 is attached to the wall for drilling, the collection component 3 is attached to the wall by pushing the component 4. The collection component 3 covers and collects the dust generated by the rotation of the drill bit 2. When the drill bit 2 needs to be replaced, the collection component 3 can be folded and stored by the positioning component 5, so that the collection component 3 no longer covers the drill bit 2.

[0039] Secondly, the first annular block 301 and the second annular block 303 are connected by a corrugated folding tube 302, enabling folding and unfolding. The second annular block 303 can be pressed against the wall by the pushing component 4. At this time, the second annular block 303 can discharge the generated dust through the discharge port 304. The dust then moves to the inside of the collection box 306 through the connecting pipe 305 on the discharge port 304. When dust accumulates at the discharge port 304, the vibration motor 307 is activated, and the vibration generated by the motor 307 circulates the accumulated dust. The first rod 403 and the second rod 404 can change angles via a rotating shaft 405. Similarly, the first rod 403 and the second rod 404 can also change angles within the first block 401 and the second block 402. At this time, the elastic force of the spring 406 pulls the second annular block 303, allowing it to be displaced and pressed against the wall.

[0040] Finally, when it is necessary to replace the drill bit 2 on the drill body 1, the hook 502 on the third block 501 is lifted, which can drive the folding of the corrugated folded pipe 302 and the displacement of the second annular block 303. When the hook 502 is hooked on the fourth block 503 of the first annular block 301, the stability of the first annular block 301, the corrugated folded pipe 302 and the second annular block 303 when folded and connected can be ensured.

[0041] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
