Abstract
The utility model discloses a self suction pressure-generation dust control device for a reciprocating drill, which comprises a dust collection chamber (4) and a telescopic pressure generation chamber (3). The dust collection chamber (4) and the telescopic pressure generation chamber (3) are formed by one-step plastic rubber injection molding, the dust collection chamber (4) is positioned at the front part of the telescopic pressure generation chamber (3), an air inlet (1) is formed at the front end of the dust collection chamber (4), an air outlet (2) is formed at the top end of the dust collection chamber (4), and a non-return valve (6) is arranged on the air outlet (2). The dust control device is installed at the drill bit of the reciprocating drill. The dust control device has simple structure, low cost and convenient installation, and generates suction pressure by using the to-and-fro impact of the reciprocating drill and sucks the generated dust into the dust collection chamber for storage, thereby realizing suction pressure dust control through the easiest way and reducing the hurt of the dust to constructors and the pollution to the site.
Description
Technical field
The utility model relates to a kind of dust guard, be specifically related to a kind of and Churn drill matching used have dust suction, dust collection function from negative pressure Churn drill dust arrester.
Background technology
At present in the installing area, the use of Churn drill is particularly frequent, as install an air-conditioner, geyser, protective screening, security door etc. all need use Churn drill, metope that Churn drill in use whitewashes on the body of wall and the cement in the wall, the broken dust that forms of fragment of brick, operation field stirs up a cloud of dust, dust causes very big harm to operating personnel's health on the one hand, on the other hand surrounding environment is caused dust pollution.Traditional Churn drill is not installed dust collect plant, and the Churn drill that has is to install dust catcher additional, and the improvement cost height is inconvenient to load and unload.For a long time, the staff wears the suction that mouth mask or protective face mask come barrier or reduce dust, and dust does not have solution to the pollution of environment, can only construct and finish the cleaning scene.
Summary of the invention
The purpose of this utility model is: provide that a kind of this dust arrester is simple in structure, and is with low cost, easy to loading and unloading from negative pressure Churn drill dust arrester, have the dust suction dust collection function with the supporting use of Churn drill.
The technical solution of the utility model is: this dust arrester comprises dust-collecting cavity and stretches into the pressure chamber, dust-collecting cavity with stretch into the pressure chamber and annotate one-shot forming by the plastic rubber mould, dust-collecting cavity is positioned at and stretches into front portion, pressure chamber, front end at dust-collecting cavity is established air inlet port, exhaust opening is established on top at dust-collecting cavity, and one way valve is installed on the exhaust opening.
Of the present utility model in negative pressure Churn drill dust arrester, on exhaust opening, establish filter screen.
Of the present utility model in negative pressure Churn drill dust arrester, on the air inlet port of dust-collecting cavity, establish sealing ring.
Of the present utility model in negative pressure Churn drill dust arrester, establish installation sleeve in the rear end of stretching into the pressure chamber.
During installation, the installation sleeve by stretching into the pressure chamber is installed in the front end of Churn drill with dust arrester, and the drill bit of Churn drill passes and stretches into pressure chamber and dust-collecting cavity; During use, the air inlet port of dust-collecting cavity is pressed on the metope, when Churn drill march forward to, stretching into pressure chamber contraction while dust-collecting cavity volume diminishes, the air that is squeezed is discharged from exhaust opening through filter screen, when Churn drill withdraws from backward, stretch into pressure chamber elongation dust-collecting cavity volume change simultaneously greatly, air sucks dust-collecting cavity from air inlet port; Because the single effect of one way valve on the exhaust opening, the drill bit of Churn drill is the formation negative pressure near the contact metope, and dust is inhaled into dust-collecting cavity with air and is collected in the dust-collecting cavity; After work a period of time, unload dust arrester, pour out the dust that is collected by air inlet port from Churn drill.
Advantage of the present utility model: on the drill bit of Churn drill, install team's dirt device additional, this dust arrester is simple in structure, with low cost, easy for installation, utilize the advance and retreat of Churn drill to impact the generation negative pressure, the dust that produces is sucked in the cavity of dust-collecting cavity and store, realized the negative pressure dust suction, reduce injury that dust brings to the constructor and the pollution that the scene is caused in the simplest mode.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, air inlet port, 2, exhaust opening, 3, stretch into the pressure chamber, 4, dust-collecting cavity, 5, filter screen, 6, one way valve, 7, sealing ring, 8, installation sleeve.
The specific embodiment
As shown in Figure 1, this dust arrester comprises dust-collecting cavity 4 and stretches into pressure chamber 3, dust-collecting cavity 4 with stretch into pressure chamber 3 and annotate one-shot forming by the plastic rubber mould, dust-collecting cavity 4 is positioned at and stretches into 3 front portions, pressure chamber, establish air inlet port 1 at the front end of dust-collecting cavity 4, establish exhaust opening 2 on the top of dust-collecting cavity 4, one way valve 6 is installed on the exhaust opening 2.
Of the present utility model in negative pressure Churn drill dust arrester, on exhaust opening 2, establish filter screen 5.
Of the present utility model in negative pressure Churn drill dust arrester, on the air inlet port 1 of dust-collecting cavity 4, establish sealing ring 7.
Of the present utility model in negative pressure Churn drill dust arrester, establish installation sleeve 8 in the rear end of stretching into pressure chamber 3.
During installation, the installation sleeve 8 by stretching into pressure chamber 3 is installed in the front end of Churn drill with dust arrester, and the drill bit of Churn drill passes and stretches into pressure chamber 3 and dust-collecting cavity 4; During use, the air inlet port 1 of dust-collecting cavity 4 is pressed on the metope, when Churn drill march forward to, stretching into pressure chamber 3 contraction while dust-collecting cavity 4 volumes diminishes, the air that is squeezed is discharged from exhaust opening 2 through filter screen 5, when Churn drill withdraws from backward, stretch into pressure chamber 3 elongations dust-collecting cavity 4 volumes change simultaneously greatly, air sucks dust-collecting cavity 4 from air inlet port 1; Because the single effect of one way valve 6 on the exhaust opening 2, the drill bit of Churn drill is the formation negative pressure near the contact metope, and dust is inhaled into dust-collecting cavity 4 with air and is collected in the dust-collecting cavity 4; After work a period of time, unload dust arrester, pour out the dust that is collected by air inlet port 1 from Churn drill.
