The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, the present embodiment, take technical solution of the present invention as prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As shown in the figure, a kind of dust-free environmental protection type electric hammer, comprise electric hammer body 1, electric hammer body is provided with electric hammer drill 2, electric hammer body 1 is provided with electric hammer drill 2, drainage tube 3 overlapped electric hammer drill 2 and was fixed on electric hammer body, as gas channel, the dust of the electric hammer drill of electric hammer body 2 surroundings is sucked its inside by drainage tube 3, and by its filtration, last dust falls in the dust tank 5 being fixed on drainage tube 3, for the ease of clearing up in time the dust of collecting in dust tank 5, dust tank 5 is dismountable to be fixed on drainage tube, for this, can with one end that drainage tube 3 docks, screw thread be set in dust tank 5, and at the interface of drainage tube 3, corresponding screw thread is set, like this, dust tank 5 just can be screwed on drainage tube, in the time that the dust in dust tank is too much, screwed and get off to pour out dust and can complete easily cleaning work, in order to make the air-flow displacement in drainage tube 3, air draft wheel 6 is housed on drainage tube, as Fig. 2, shown in Fig. 3, described air draft wheel 6 comprises blade 602, blade main shaft 603 and peripheral housing 601, housing 601 is the tubular of an end opening, its bottom is provided with multiple vents 7, blade main shaft 603 is through the bottom of housing 601, its part that blade 602 is housed is positioned at housing 601 inside, blade main shaft 603 drives running by motor 8, in the time that blade main shaft 603 rotates, the rotation of blade 603 can make gas in housing 6 flow to bottom and discharge from vent 7 that (air draft is taken turns 6 action principles and is similar to existing centrifugal fan market from its openend, can be substituted by it), take turns 6 o'clock in installation air draft, make its air inlet as butt end, air draft wheel 6 is communicated with drainage tube 3, to make air draft wheel 6 can make the gas flow air draft wheel 6 in drainage tube 3 and flow out from the vent 7 of air draft wheel bottom, in order to reach dust collecting effect, need take turns 6 in air draft, with the connectivity part of drainage tube 3, a basket strainer 9 is set, as shown in Figure 4, one makes it to be gathered in basket strainer 9 for collecting dust, in the time that the dust on basket strainer reaches a certain amount of, can come off because of the vibration producing in the time that electric hammer drill 2 is normally worked, finally fall into dust tank 5, if there is clogging in basket strainer 9, can be by slightly knocking processing, or remove air draft wheel 6, cleaning or replacing basket strainer 9.
For reasonably configuration drainage tube 3, dust tank 5, air draft wheel 6 and motor 8 take up space, here there are two kinds of embodiment, one, can select the drainage tube 3 of tubular, air draft wheel 6 is set above drainage tube 3, dust tank 5 is thereunder set, and make air draft wheel 6 relative up and down with dust tank 5, as shown in Figure 6, motor 8 is arranged on air draft wheel 6 one end with vent 7, like this, motor 8 drives 6 runnings of air draft wheel, air-flow in drainage tube 3 is drawn to air draft wheel 6, dust is filtered and unified collection in dust tank 5 through basket strainer 9 simultaneously; Two, the shape of drainage tube 3 can be done to reasonable conversion, for example, drainage tube 3 is made to two sections, be respectively horizontal segment 301 and vertical section 302, as shown in Figure 5, its horizontal segment 301 overlapped electric hammer drill 2 and was fixed on electric hammer body, and vertically section 302 forms T font with horizontal segment vertical connection, air draft wheel 6 is fixed on vertical section 302 of drainage tube 3, and dust tank 5 is located at the bottom of vertical section 302.
The arrangement mode of drainage tube 3, dust tank 5 and air draft wheel 6 is not limited to above-mentioned several, and those skilled in the art can reasonably change according to scheme disclosed by the invention, will not enumerate at this.
Because drainage tube 3 overlapped electric hammer drill 2 and was fixed on electric hammer body, this makes drainage tube 3 may hinder the normal operation of electric hammer drill 2, for this, can suitably control the length of drainage tube 3, and at its front end, a trumpet-shaped dust gathering arrester 4 is set, this dust gathering arrester 4 is the radial front end that is fixed on drainage tube 3 by multiple strip tapes and forms, in the time that wall is crept in the normal work of electric hammer drill 2, dust gathering arrester 4 can push backward and spread out under the barrier effect of wall, not only can not affect the normal operation of electric hammer drill 2, also can form a barrier ring and stop that dust spreads to outside, more be conducive to drainage tube by the guiding of dust collection.
The present invention does not narrate part for prior art.
