Abstract
The utility model discloses a dust suction device of an electric cutting tool, which comprises an electric cutting tool, wherein the electric cutting tool comprises a saw blade, a saw blade guard and a motor for driving the saw blade to rotate, the tail part of the saw blade guard is provided with a chip discharging hole, one end of a motor shaft of the motor is connected with the saw blade through a transmission box, the other end of the motor shaft extends to the tail part of the motor and is connected with a fan blade, the tail part of the motor is provided with a dust suction cover, the dust suction cover comprises a dust suction hole and a dust outlet, the dust suction hole is connected with the chip discharging hole through a pipe body, and the dust outlet is connected with a dust suction bag through a chip discharging pipe. The motor shaft is lengthened, and the characteristic that the rotating speed of the motor shaft is more than that of the saw blade, the fan blade is arranged on the motor shaft to ensure that a huge suction force is generated, therefore, wood chips, plastic chips and other chips generated in a cutting process are sucked into the dust suction bag, the dust removal efficiency is greatly increased, and the dust suction rate can reach above 90 percent.
Description
Technical field
The utility model relates to a kind of electric cutting tool, is specifically related to a kind of dust exhaust apparatus of electric cutting tool.
Background technology
At present, common electric cutting tool has diagonal cutting saw, bench saw and compound saw etc., and these electric cutting tools usually can produce dusts such as wood chip, plastics bits in the process of cut workpiece.The prior electric cutting tool in order to collect dusts such as cutting chip, generally is the bits pipe to be installed out and to be connected dust collecting sleeve at the afterbody of blade shroud, and like this, the dust that in cutting process, produces just can get in the dust collecting sleeve.But this dedusting method only is to collect the dust that is scattered out automatically passively, and dust removing effects is undesirable.
The utility model content
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the utility model provides the dust exhaust apparatus of the high electric cutting tool of a kind of pick-up performance.
Technical scheme: for solving the problems of the technologies described above, the dust exhaust apparatus of the electric cutting tool of the utility model comprises electric cutting tool; This electric cutting tool comprises saw blade, blade shroud and driving saw blade motor rotating; The afterbody of said blade shroud is provided with the crumb mouth, it is characterized in that: motor shaft one end of said motor is connected with saw blade through gearbox, and the motor shaft other end extends to the motor afterbody and is connected with fan blade; The motor afterbody is equipped with dust shield; Dust shield comprises suction port and dust mouth, and said suction port is connected with the crumb mouth through body, and said dust mouth is connected with dust collecting sleeve through going out the bits pipe.
Said dust shield comprises left dust shield and right dust shield, and said left dust shield and right dust shield dock engaging each other and form the dust suction space.
Said left dust shield outer wall is equipped with end cap.
Said electric cutting tool is a diagonal cutting saw, or bench saw, or compound saw.
Beneficial effect: the dust exhaust apparatus of the electric cutting tool of the utility model, structure is ingenious, through motor shaft is extended; Make full use of the characteristics of motor rotational shaft speed greater than the saw blade rotating speed; Fan blade is installed on motor shaft is made it produce huge suction, thereby chip such as the wood chip that produces in the cutting process, plastics bits and dust are sucked in the dust collecting sleeve, improved efficiency of dust collection greatly; Pick-up performance is very good, and the dust clean absorption rate can reach more than 90%.In addition, the utility model only needs on the basis of existing electric cutting tool, just simply to install and can use, and is with low cost, helps promoting the use of.
Description of drawings
Fig. 1 is the fractionation structural representation of the utility model;
Fig. 2 is the package assembly sketch map of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
As depicted in figs. 1 and 2, the dust exhaust apparatus of the electric cutting tool of the utility model comprises electric cutting tool; This electric cutting tool comprises saw blade, blade shroud 1 and drives saw blade motor rotating 2; The afterbody of blade shroud 1 is provided with crumb mouth 4, and motor shaft 3 one ends of motor 2 are connected with saw blade through gearbox, and motor shaft 3 other ends extend to motor 2 afterbodys and are connected with fan blade 5; Motor 2 afterbodys are equipped with dust shield 6; Dust shield 6 comprises suction port 7 and dust mouth 8, and suction port 7 is connected with crumb mouth 4 through body 9, and dust mouth 8 is managed 10 and is connected with dust collecting sleeve 11 through going out to consider to be worth doing.
In the present embodiment, dust shield 6 comprises left dust shield 61 and right dust shield 62, and left dust shield 61 docks engaging each other with right dust shield 62 and forms the dust suction space; Left side dust shield 61 outer walls are equipped with end cap 12, and right dust shield 62 outer walls are provided with some installing holes 13.The rotating speed of electric cutting tool motor shaft 3 reaches 23000 rev/mins usually; Rotating speed through gearbox gear proportioning rear output shaft is that the saw blade rotating speed has only 4000 rev/mins; The rotating speed great disparity at two places is very big; The suction that produces just has very big difference, and crumb mouth 4 is just different with the dust removal ability at 8 places, dust mouth.On motor shaft 3, increase by a fan blade 5, its dust removal ability will be stronger.
The utility model in use, after motor 2 started, fan blade 5 was along with the rotation of motor shaft 3 produces suction, and the dust at 4 places, crumb mouth is sucked the suction port 7 of dust shields 6 through body 9, through the dust mouth 8 and get into dust collecting sleeves 11 through going out bits pipe 10.The pick-up performance of the utility model is very good, and the dust clean absorption rate can reach more than 90%.
In the present embodiment, electric cutting tool is a diagonal cutting saw.The technical staff in present technique field expects that easily this structure is equally applicable to electric cutting tools such as bench saw or compound saw.As long as electric cutting tool has members such as saw blade, blade shroud 1 and driving saw blade motor rotating 2, just assemble according to present embodiment easily.
The above only is the preferred implementation of the utility model; Be noted that for those skilled in the art; Under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection domain of the utility model.
