Description

The free from dust makita 4100NH

Technical field

The utility model relates to a kind of electronic stone material cutting tool, belong to the electric tool class.

Background technology

In the prior art, the technology of electric marble cutter is quite ripe, and is widely used in the cutting processing of stone materials such as ceramic tile, cement plate, marble.Also can inquire similar disclosed technology on patent gazette, its primary structure content includes casing, motor, gear-box and cutting tool etc.Motor drives cutting tool by the transmission of power of gear-box, as the high speed rotation of cutting blade, thereby reaches the purpose that stone material is cut.But described makita 4100NH exists unavoidably and produces the big problem of dust in the cutting process when reality is used; Moreover, cutting blade contacts with stone material under the high-speed cutting state, can produce high heat, even the ejection spark, has aggravated the wearing and tearing of cutting tool.It is big that therefore present common electronic stone material cutting tool ubiquity dust, be harmful to the healthy of operator, influence the surrounding environment health, the cutting tool quick abrasion, service life is short, needs often to change, and the height that produces during cutting is warm or sparks flying off in all directions, cause operator's industrial accident easily, defective such as security is relatively poor.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and a kind of prior art is improved, free from dust makita 4100NH of having water injector is provided.It mainly includes casing, motor, gear-box, cutting tool, be provided with in the handle that described casing top links to each other at least one be installed in casing in the water inlet pipe that links to each other of micro pump, micro pump is positioned at the top of gear-box working gear, and the working gear axle links to each other with micro pump, and the effluent pipe mouth of at least one micro pump is installed in the guard shield of cutting tool.The guard shield Front-end Design plagiocephaly, plagiocephaly is near blade, the dust that it produces when pressing the blade running and the parabola Position Design of fragment, make dust and fragment throw to the place ahead, and hurt sb.'s feelings in the front that can not fly to the people along plagiocephaly.It has utilized the technology of three aspects this machine, and promptly water, wind, plagiocephaly reach and do not hurt sb.'s feelings.

The top edge design of the protecgulum of described gear-box has at least one ventilation slot, facing ventilation slot in the guard shield of cutting tool is provided with at least two and makes wind air-out notch forwards, described micro pump outlet pipe design is in above-mentioned ventilation slot and air-out groove, and the front end of described guard shield is provided with a plagiocephaly.

The cycling switch of a control water yield is equipped with in described gear-box outside, and it can return water inlet pipe to the unnecessary water yield of control cycling switch, reaches according to the different stone materials of cutting and just in time removes dust and do not have sewage and flow out.Because what the unnecessary water of manual water spray became effluent stream is everywhere, cycling switch has been arranged, just can reach the cleaning free from dust.On the handle that links to each other above the casing, power switch is installed, and power line and water inlet pipe attach together in the handle above casing.Its water inlet pipe people in the past is contained on the base " water spray " with a water pipe exactly this is state-of-the-art, and it is pretty troublesome so still to have more a water pipe in operating process.Utilize a sleeve pipe that water pipe and electric wire are fitted together now,, reach practical and convenient if operating personnel have cut brokenly the replacing of can releasing of water pipe or electric wire because of carelessness.Its water source is in the past also pretty troublesome, has just utilized useless Coke bottle to adorn water now, and water inlet pipe is inserted, and water inlet pipe can extend as required when the cutting metope, has reached flexible water supply.

The utility model compared with prior art has rational in infrastructurely, compact, easy to use, and security, good reliability can significantly reduce the generation of dust, can reduce the operating temperature of cutting tool, prolong the characteristics such as service life of cutting tool.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a gear box structure schematic diagram of the present utility model.

Fig. 3 is the structural representation of gear box cover of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model mainly includes casing 1, motor 2, gear-box 3, cutting tool 4, be provided with in the handle 5 that described casing 1 top links to each other at least one be installed in casing 1 in the water inlet pipe 7 that links to each other of micro pump 6, micro pump 6 is positioned at the top of gear-box 3 working gears 8, and working gear axle lengthening back links to each other with micro pump 6, and drive micro pump 6 and carry out work, the effluent pipe mouth 9 of at least one micro pump 6 is installed in the guard shield of cutting tool 4.The guard shield Front-end Design plagiocephaly 14, plagiocephaly is near blade, the dust that it produces when pressing the blade running and the parabola Position Design of fragment, make dust and fragment throw to the place ahead, and hurt sb.'s feelings in the front that can not fly to the people along plagiocephaly.It has utilized the technology of three aspects this machine, and promptly water, wind, plagiocephaly reach and do not hurt sb.'s feelings.

In conjunction with Fig. 2 and shown in Figure 3, the top edge design of gear box cover described in the utility model has at least one ventilation slot 10, face ventilation slot 10 and be provided with at least two and make wind air-out notch 11 forwards in the guard shield of cutting tool 4, described micro pump 6 outlet pipes design is in above-mentioned ventilation slot 10 and air-out groove.

The cycling switch 12 of a control water yield is equipped with in gear-box described in the utility model 3 outsides, and it can return water inlet pipe to the unnecessary water yield of control cycling switch, reaches according to the different stone materials of cutting and just in time removes dust and do not have sewage and flow out.Because what the unnecessary water of manual water spray became effluent stream is everywhere, cycling switch has been arranged, just can reach the cleaning free from dust and on handle 5 continuous above the casing 1, power switch 13 is installed, and power line and water inlet pipe 7 attach together in the handle 5 above casing 1.Its water inlet pipe 7 people in the past is contained on the base " water spray " with a water pipe exactly this is state-of-the-art, and it is pretty troublesome so still to have more a water pipe in operating process.Utilize a sleeve pipe that water pipe and electric wire are fitted together now,, reach practical and convenient if operating personnel have cut brokenly the replacing of can releasing of water pipe or electric wire because of carelessness.Its water source is in the past also pretty troublesome, has just utilized useless Coke bottle to adorn water now, and water inlet pipe is inserted, and water inlet pipe can extend as required when the cutting metope, has reached flexible water supply.

The utility model is a kind of improvement to prior art, thus some technology contents of not relating to of this paper are identical with original technology or those of ordinary skills can be on top of routine techniques.

Because the utility model is a kind of improvement to prior art, its volume and weight and original cutting machine do not have big variation, the purpose of water spray free from dust when it utilizes water finely to reach work with the dust principle of combining, also solved the problem of cutting blade heating simultaneously, increase the service life of cutting tool, the wind that can also fall the motor cooling simultaneously uses, and the fractionlet that produces when reaching moistening dust and cutting blows to the place ahead, reaches inoffensive purpose.Therefore, the utility model will have a kind of possibility that substitutes, upgrades existing cutting machine product.
