Description

The sander of a kind of building wall with centrifugal blower
Technical field
The utility model relates to the sander of a kind of building wall with centrifugal blower, 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 the sander of a kind of building wall with centrifugal blower, its compact conformation, small volume, lighter in weight, convenient operation, and adopts centrifugal blower to collect dust, is beneficial to environmental protection.
In order to achieve the above object, the utility model adopts following technical scheme: the sander of a kind of building wall with centrifugal blower, comprise handle, with motor-driven sand mill and centrifugal blower, 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, and described output shaft is connected with described mill and centrifugal blower respectively, to be with movable grinding disc and centrifugal blower running; Motor is connected with planetary gear speed reducing mechanism by motor output shaft, described planetary gear speed reducing mechanism is made up of planet circular system and reducer shell with matching, planet circular system comprises the first centre wheel, the second centre wheel and planetary gear, and 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 planetary gear speed reducing mechanism, has saved space, makes simple and compact for structure.In addition, in prior art, dust collected by usual vacuum cleaner, and the dust produced in the wall surface grinding machine course of work is siphoned away by the sweep-up pipe of handle rear end, but because handle is longer, will pull hose in operating process and carry out work, hose should easily be changed, again fixation; And the utility model adopts small-sized centrifugal blower to replace vacuum cleaner, the dust in bruting process is centrifuged blower fan and takes away discharge, eliminates the use of sweep-up pipe.
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 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, the described centrifugal blower other end is connected with filter bag.
As further preferred, described filter bag comprises at the bottom of bag and bag, and cylindrically, bag one end is fixedly connected with at the bottom of bag bag, and the bag other end is opening, and described bag surface is provided with the annular groove that circumference extends.Because bag surface is provided with the annular groove of circumference extension, compared with the bag of prior art cylindrical shape, in the utility model, the surface area of bag increases.In the unit interval, filter bag of the present utility model can filter more dust, improves filter efficiency.In addition, it is more that annular groove is arranged, and filter efficiency is higher.
As further preferred, the degree of depth of described annular groove reduces successively from the opening to bag at the bottom of bag.The wind contributing to like this blowing from the opening part of bag impacts annular groove, guarantees that dust is washed from annular groove.
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.Adopt centrifugal blower and filter bag to collect and Chalk-dust filtering, efficiency is high, overcomes in prior art the shortcoming using sweep-up pipe etc.
