Technical field
The present invention relates to a kind of electric hammer, specifically a kind of dustless environment protecting electric hammer punched for metope.
Background technology
In the course of work of electric hammer, it will usually many dust are produced because of vibration, these dust spread in working environment In, after operating personnel's suction lung, lung can be caused uncomfortable, gently then cough, throat are uncomfortable, it is heavy then cause silicosis, can be to operating The body of personnel causes great injury, has a strong impact on the healthy and operating efficiency of workman, and to the environment of surrounding Certain pollution can be caused, is shown through investigation, building dust is one of producing cause of today's society haze weather;
At home and abroad someone studies the dust arrester of electric hammer, but it is very few really to be able to use the dust extraction unit for electric hammer of production work See, the even existing dust extraction unit for electric hammer that can be produced and come into operation, its efficiency of dust collection is very low, and price It is particularly expensive, it is difficult to above to accomplish really popularization in application, moreover, existing improved electric hammer is all greatly in electric hammer sheet Body running side installs a telescopic dust gathering arrester additional, although this structure can improve the dust catching efficiency of dust gathering arrester to a certain extent, But because the operationally continuous earthquake motion of electric hammer body, dust gathering arrester can be caused to fail timely and effectively shifting synchronous with electric hammer body It is dynamic to cause a large amount of dust to escape, operating personnel and environment are had undesirable effect.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of dustless environment protecting that metope is punched that is used for of good dedusting effect Electric hammer.
The present invention be solve the technical scheme that is used of above-mentioned technical problem for:A kind of dustless environment protecting punched for metope Electric hammer drill is housed on electric hammer, including electric hammer body, electric hammer body, one is additionally provided with and covered electric hammer drill and be fixed on electric hammer sheet Drainage tube on body, the bottom of drainage tube is provided with dust tank, and the one end of the drainage tube away from electric hammer body is fixedly connected with Equipped with that can make the air draft mechanism of its inner air directed flow on one dust gathering arrester, drainage tube, the dust gathering arrester is can be along center The flexible suction disk-like structure of axis direction, the side of dust gathering arrester is connected with drainage tube, and the opposite side of dust gathering arrester is open provided with one, The open side of dust gathering arrester is provided with an extension board in a ring, is arranged with along the central axial direction of dust gathering arrester on extension board some Close to the side of electric hammer drill provided with a first cylindric barrier plate on individual suction port, extension board, in the outer of the first barrier plate Portion is also arranged with the second barrier plate of cylindrical shape, and the second barrier plate is fixedly connected on extension board, in the first barrier plate excircle Formed between face and the second barrier plate inner peripheral surface and an axle sleeve is fixedly connected with a mounting groove, mounting groove, the axle sleeve includes Outer shaft and internal axle sleeve, internal axle sleeve are set on electric hammer drill, and an inner ring and internal axle sleeve outer wall are arranged with internal axle sleeve excircle The bearing being connected, bearing outer ring is in contact with outer shaft inwall, and described outer shaft one end is fixedly connected in mounting groove, outer shaft The other end of set is provided with a sliding groove, and outer shaft can be slided along sliding groove on the excircle of bearing;
The inwall of the drainage tube is provided with dust-proof foam;
Horizontal range between side and extension board of the electric hammer drill away from electric hammer body is 0.5-1CM;
The air draft mechanism is by motor-driven small-sized fanses;
The internal axle sleeve is provided with a dust excluding plate close to the side of the first barrier plate, and the dust excluding plate is set in the cylindrical of electric hammer drill Zhou Shang.
What the present invention was brought has the beneficial effect that:A kind of dustless environment protecting electric hammer punched for metope of the present invention is in work When, in the presence of the frictional force between outer shaft and bearing top circle are all, extension board is fitted tightly on wall, works as electric hammer drill During into wall, extension board needs to overcome outer shaft with driving outer shaft in the cylindrical of bearing after the frictional force on bearing top circle week Slided on week, in this process because there is the presence of frictional force, outer shaft can provide a thrust all the time makes extension board tight Close to be fitted on wall, brought certain cushioning effect that shaken moreover, thrust can also work electric hammer is of the invention Dust removing effects are good, install and change all more convenient, are easy to combine with existing electric hammer, its overall performance is safe and reliable, dedusting Efficiency high, compares and is adapted to use in complicated construction operation environment, can effectively improve the working environment of operating personnel.
