Description

Dustless wall-slotting machine

(1) technical field

The utility model relates to a kind of electric tools of building hydropower installation engineering and decorative engineering, particularly a kind of healthy dustless wall-slotting machine of operating personnel of protecting.

(2) background technology

In the modern architecture decorative engineering, in order to guarantee the smooth attractive in appearance of metope, all indoor cablings (comprising illuminating line, various electric appliance circuits and pipeline) all are to adopt concealed wire to bury underground, before buried line pipeline, the construction of PPR water supply line, must slot to body of wall.Present most of fluting work is finished by semi-mechanization is manual, and labour intensity is very big, and is particularly all the more so when the building eminence is constructed.

Though groover is being updated now, be directed to factors such as environmental protection, weight, price not enough; Simultaneously; most groovers do not have protective cover, fragment and the dust that produces in the metope grooving process are not had the favorable protection effect, even if the groover that has is provided with protective cover; protect body not to be damaged to a certain extent, but still can't eliminate the dust that produces in the groover use.

(3) summary of the invention

The utility model provides the dustless wall-slotting machine of a kind of light practicality, effective dedusting in order to remedy the deficiencies in the prior art.

The utility model is achieved by the following technical solution:

A kind of dustless wall-slotting machine, comprise casing, be positioned at the casing back handle, be installed in casing motor, be loaded on the casing head cutter with protective cover and be connected motor and the reducer of cutter and output shaft, its special character is: the bottom surface that described casing cutter stretches out is provided with the dust collecting chamber; Dust collecting chamber bottom surface is fixed with last dust board, the following dust board that can shrink from top to bottom and collects baffle plate, and last dust board and following dust board are stranded mutually; On dust collecting chamber shell, last dust board and the following dust board saw blade groove corresponding with cutter arranged all, the saw blade groove below of dust collecting chamber bottom surface is provided with the control of dust hole.

The interior cutter that centers on of cavity of going up dust board and following dust board composition described in the utility model is provided with the sponge filtration beds.

Cutter passes casing, dust collecting chamber, upper and lower dust board successively by installing, and its tip edge is exposed outside.The dust that the setting of dust collecting chamber produces cutter in the course of the work is collected, and by terminal dust flue discharge, can connect the dust apparatus for placing in the dust flue lower end herein, prevent because the environment pollution that stirs up a cloud of dust and cause is fallen short of success for lack of final effort the dustproof work of groover.

The activity of last dust board, following dust board and collection baffle plate is shunk cutter is surrounded closely, be convenient in time collect the dust that cutter carries, sponge filtration beds in last dust board and the following dust board cavity can be finished the cleaning work to cutter, prevent cutter because rotation is too fast, dust is scattered, and the effect of collecting baffle plate is to collect the dust that upper and lower dust board can't be collected, and accomplishes comprehensive protection.

Along with groover to going deep within the walls, upper and lower dust board and connection baffle plate are compressed, the dust of collecting in the baffle plate can be followed air communication to cross the control of dust hole to enter the dust collecting chamber, removed the space between upper and lower dust board along with the compression of baffle plate and deadweight, for further control of dust is ready.

The filtering exhaust mouth that dust collecting chamber end described in the utility model is provided with dust flue and communicates with dust flue, the filtering exhaust mouth is by the shutoff of porous filtering baffle plate, be placed with the sponge contour on the porous filtering baffle plate with the dust flue import, can only help reducing the air pressure inside of dust collecting chamber by the fresh air after being filtered herein.The position of filtering exhaust mouth is provided with and does not limit herein, can extend downwards according to construction requirement, and related spongy layer and porous filtering baffle plate are to bottom offset.

In order not influence the use of cutter, the taking up room of dust collecting chamber that needs will be connected outside the casing is controlled at the little scope of trying one's best, therefore the dust collecting chamber is because the continuous accumulation of dust, limited space will soon be filled full, in order not influence the lasting use of groover, lower end at the dust collecting chamber is provided with dust flue, so that the dust of accumulating in the dust collecting chamber is discharged; Dust flue one side branches out the filtering exhaust mouth that communicates with the dust collecting chamber, helps the balance of dust collecting chamber internal gas pressure, makes the discharging of dust not be subjected to the influence of air pressure; The filtering exhaust mouth is shutoff with the porous filtering baffle plate, and on baffle plate, place sponge, the dust that helps to stop collection is emitted or the porous filtering baffle plate is stopped up from the filtering exhaust mouth, and the height of sponge is set to the dust flue import contour, can make the dust of being tackled by sponge enter dust flue smoothly.

On the dust board limiting plate is installed under described in the utility model, limiting plate is connected on the dust collecting chamber by limited screw.Because the upper and lower dust board that connects can movablely shrink, in order not make two dust boards stretch out the cutter tip edge, on the dust collecting chamber, pass through limited screw fixed limit plate, and the other end of limiting plate is fixedly hung on down on the dust board, make two dust boards can not continue to expand outwardly; The position of limiting plate can be arranged on down on the dust board, also can be arranged on the dust board, is set to suitable for the definite of position with convenient installation.

Described in the utility model go up dust board, down dust board and collect on the baffle plate all be fixed on the dust collecting chamber on spring be connected.After upper and lower dust board and collection baffle plate are compressed, for the ease of the automation of using, simplify step by artificial reduction dust board position, at upper and lower dust board, collect to be connected respectively between baffle plate and the dust collecting chamber spring assembly be set, when they not by compression the time, make it go back original position automatically by spring, the convenient actual operation of using.

Advantage of the present utility model is:

(1) fuselage is light, and one-hand operation reduces fatigue, is convenient to high-rise working;

(2) a plurality of saw blade grooves can be set, be suitable for installing a plurality of cutters,

(3) low price;

(4) dedusting, environmental protection can make dust reduce more than 80% during the cutting metope, also can human body not had harm substantially through filtering even if flue dust is emerged from exhaust opening, is beneficial to the protection health of operators.

(5) simple and reasonable, dust discharge and good dustproof effect, long service life, reliability and safety are good.
