Description

Technical Field

[0001] The utility model belongs to the technical field of construction tools, and particularly relates to a drilling dust prevention device for construction. Background Art

[0002] Impact drills are often used in construction. Impact drills rely on the rotation and impact of the drill bit to achieve drilling operations. During the drilling process, a large amount of dust and debris will be generated, which not only pollutes the air environment, but also causes health problems for operators who inhale a large amount of dust. In order to solve this problem, operators usually only add a protective cover to the front end of the impact drill to prevent dust and debris from splashing. However, this method has the following problems:

[0003] 1. It is difficult to grasp the required drilling depth when drilling, and the conventional dust cover cannot be adjusted accordingly according to the required drilling depth. Therefore, the dust cover cannot completely cover the dust cover during the entire drilling process, and there are still problems such as dust and debris flying around; 2. The dust cover that is not installed on the drilling machine needs the operator to press it against the wall during operation, and then insert the drill bit of the drilling machine into the dust cover for operation. This operation can prevent dust from flying throughout the process, but this operation method is more dangerous and the work efficiency is not high; 3. Common dust covers are only directly covered on the wall to prevent dust, but cannot collect the drilled dust. Therefore, the drilled dust will accumulate in the area where the dust cover and the wall are in contact. After the drilling is completed, when the drill bit of the drilling machine withdraws from the hole, the dust accumulated on the wall will fall from the port of the dust cover and pollute the working environment.

[0004] Therefore, in order to solve the above problems, it is urgent to design a construction drilling dust prevention device. Utility Model Content

[0029] Example

[0030] like Figure 1 to Figure 2 As shown, a construction drilling dust prevention device includes a drilling machine 100, and the drilling machine 100 is provided with a dust prevention device 200, and the dust prevention device 200 is sleeved on the drilling end of the drilling machine 100, and is mainly used for preventing the drilling dust from splashing during the drilling process of the drilling machine 100, preventing dust, and ensuring cleanliness during the working process;

[0031] The dust prevention device 200 includes a back-blowing portion 210, a dust collecting portion 220 and a dust prevention sleeve assembly 230. Specifically:

[0032] The blow-back portion 210 includes a fan blade 211, a blow-back pipe 212, a rotating shaft 213, a driving pulley 214, a driven pulley 215 and a linkage belt 216. The blow-back pipe 212 is installed on the dust-proof sleeve assembly 230 and is connected to the dust-proof sleeve assembly 230. The rotating shaft 213 is rotatably installed in the blow-back pipe 212. The driving pulley 214 is installed on the chuck of the drilling machine 100 (the driving pulley 214 moves synchronously with the chuck of the drilling machine 100 but does not affect the clamping operation of the chuck). 15 is installed on the rotating shaft 213, the linkage belt 216 connects the driven pulley 215 and the driving pulley 214, and the fan blade 211 is installed on the rotating shaft 213. When drilling, the driving end of the drilling machine 100 drives the fan blade 211 to rotate to generate an inward airflow, and the back-blowing airflow flows in from the back-blowing duct 212 to blow the drilled dust accumulated at the place where the dust-proof device is close to the wall into the dust collecting part 220, so as to prevent the drill bit from withdrawing from the hole after the drilling operation is completed, and the accumulated dust is scattered from the wall to pollute the working environment.

[0033] In the present invention, the anti-dust sleeve assembly 230 includes an anti-dust sleeve 231, a mounting seat 232, a spring 233 and a side shell 234. The mounting seat 232 is mounted on the drilling machine 100, and the spring 233 is mounted in the mounting seat 232. The anti-dust sleeve 231 is slidably arranged in the mounting seat 232. A rubber ring is provided on one end of the anti-dust sleeve 231 that is close to the wall. The inner end of the anti-dust sleeve 231 abuts against the spring 233, and the outer end is used to close to the wall. The spring 233 is adapted to the drilling hole. The depth of the drilling hole is continuously deepened by compressing the spring 233 through the anti-dust sleeve 231 to realize the adjustment operation, ensuring that the anti-dust sleeve 231 is always in close contact with the wall surface during the whole process of drilling, ensuring that no dust occurs during the whole process. The side shell 234 is snap-fitted and installed on the anti-dust sleeve 231 and corresponds to the chuck position of the drilling machine 100. The purpose of setting the side shell 234 is to facilitate the drilling machine 100 to clamp drill bits of different specifications or to adjust the blowback part 210 accordingly.

[0034] Furthermore, an exhaust port 2311 is provided on the anti-dust sleeve 231, and a filter is provided on the exhaust port 2311. The purpose of setting the exhaust port 2311 is to ensure that the pressure inside the anti-dust sleeve 231 is the same as the external pressure, so as to avoid the backflow of air from stirring up dust in the anti-dust sleeve 231. The filter can isolate dust particles and ensure that the dust collected in the dust collection part 220 will not overflow. Specifically, the exhaust port 2311 is set vertically upward.

[0035] Furthermore, the dust outlet 2312 and the anti-dust sleeve 231 are connected in an arc transition, so that the collected dust can fall into the dust collecting part 220 better.

[0036] In the present invention, the dust collecting part 220 and the anti-dust sleeve assembly 230 are made of transparent plastic. The transparent material allows for more intuitive observation of the working conditions inside the anti-dust device and whether the dust collected in the dust collecting part 220 is full.

[0037] To sum up, the utility model provides a construction drilling dust prevention device, which can use the drive of the drilling machine itself to drive the introduction of airflow at the back-blowing part, and blow the drilled dust accumulated at the place where the dust prevention device is close to the wall surface into the dust collecting part, so as to prevent the drill bit from withdrawing from the hole after the drilling operation is completed, and the accumulated dust from scattering from the wall surface to pollute the working environment; the dust prevention device provided in the utility model can also be adjusted accordingly with the depth of the drilling hole, and always keep close to the wall surface during the drilling process to prevent dust and debris from splashing during the drilling process; the dust prevention device provided in the utility model is also provided with a dust collecting part, which can uniformly collect and process the dust drilled during the drilling process.
