Description

A kind of building wall sander
Technical field
The utility model relates to a kind of building wall sander, belongs to architecture construction technical field.
Background technology
Polishing putty layer is that building wall sprays paint or one critical process before mopping, and whether metope is smooth attractive in appearancely depends on polishing quality to a great extent.The most polishing of employing traditional-handwork metope, i.e. hand-held sand papering in current construction and decoration.Not only efficiency is low for traditional-handwork polishing metope, and application workman dust when polishing metope flies upward all over the sky, although their fully armed protection, still can work the mischief to its health.During polishing metope, dust is diffused into air, also causes severe contamination to surrounding environment.In addition, the high and dynamo-electric grinding apparatus of environmental protection of a kind of efficiency is studied, significant for guarantee workers ' health, protection of the environment, raising operating efficiency and polishing quality.China Patent No. 200710193709.8 discloses the manual grinding dust removing device of a kind of metope for room, end face manual grinding operation, it comprises: Abrasive paper support, motor, flexible pipe, storage dirt device, although it considers the impact on environment, the dust of polishing is collected and enters storage dirt device, but it still adopts manual grinding, inefficiency.
Summary of the invention
Main purpose of the present utility model is to provide a kind of building wall sander, its compact conformation, small volume, lighter in weight, convenient operation, and can collect dust, is beneficial to environmental protection.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of building wall sander, comprise handle, with motor-driven sand mill and connected vacuum cleaner, described sand mill comprises motor, planetary gear speed reducing mechanism and mill, planetary gear speed reducing mechanism is provided with between described mill and motor, planetary gear speed reducing mechanism comprises output shaft, this output shaft is connected with the steel seat of described mill, motor is connected with planetary gear speed reducing mechanism by motor output shaft, described planet gear reducing mechanism is made up of planet circular system and reducer shell with matching, planet circular system comprises the first centre wheel, second centre wheel and planetary gear, described planet circular system is arranged in described reducer shell, described motor output shaft is connected with described first centre wheel, and described second centre wheel is connected with mill.Above-mentioned motor can export the power of low-speed big under the transformation of planet gear reducing mechanism, has saved space, makes simple and compact for structure.
As further preferably, described planetary gear is 3,3 planetary gears be arranged so that the utility model is more stable in strength transmission, transmission better effects if.
As further preferred, three planetary gears are evenly distributed between the first centre wheel and the second centre wheel with the angle of 120 ° each other.
As further preferred, described vacuum cleaner adopts hose and air exhauster to aspirate and sock filtration, and vacuum cleaner is connected with mill.
As further preferably, be radially provided with handle in the peripheral surface of described motor.
As further preferred, described handle is hollow handle, further weight reduction.
As further preferred, described motor adopts individual event series machine, and individual event series machine has the torque-speed characteristic that rotating speed is high, volume is little, starting torque is large, overload power is strong and soft.
As further preferred, described mill comprises grinding disc body, locker is fixed with in the middle part of the back side of described grinding disc body, described grinding disc body is positioned at around locker and is distributed with multiple air suction opening, described air suction opening tilts along the direction of rotation of grinding disc body, makes air suction opening rearwardly produce wind-force when grinding disc body rotates.Wall surface grinding machine is when polishing body of wall, and grinding disc self rotates and produces wind-force, the dust produced is blowed to dust shield, then is siphoned away by dust by sweep-up pipe, improve pick-up performance during polishing.
The beneficial effects of the utility model are: individual event series machine is under output identical power conditions, and rotating speed is higher, and weight is lighter, therefore, should select pot motor for alleviating weight of equipment.And in the meticulousr polishing constructions such as polishing building wall face putty layer, require that the working speed of sanding disc is lower, therefore need between motor output shaft and sanding disc, arrange the larger reducing gear of speed reducing ratio.For the sand mill of meticulousr polishing construction in prior art, usually adopt two-stage spur gear to slow down, to improve rotating ratio, but such sand mill Heavy Weight, volume are large, operation uses very inconvenient.Due to Planetary Gear Transmission, there is the transmission of power dividing and each centre wheel formation coaxial line formula and reasonably apply internal gear pair, its compact conformation, volume therefore can be made little and lightweight.The 1/2-1/5(that the contour dimension of general Planetary Gear Transmission and weight are about ordinary gear transmission is bearing under identical load-up condition).In addition the efficiency of Planetary Gear Transmission is also high.Therefore adopt planetary gear speed reducing mechanism to make dust suction sand milling compact conformation, volume little and lightweight.
