Description

Remote control dust suction scrubbing brush machine

The utility model relates to a kind of remote control dust suction scrubbing brush machine of the usefulness that erases the board, and suitable especially various planes blackboard uses.

Existing various manual dust-sucking eraser or electric dust absorption blackboard eraser, each have their own strong point, but generally speaking, manually dust-sucking eraser has only solved dust problem, do not solve labour intensity, the electric dust absorption blackboard eraser has solved dust suction and labour intensity, but strict to the blackboard planar smoothness, the plate face has injustice slightly, may cause indivedual local wipings unclean, influenced result of use, wipe unclean reason with regard to it, mainly be to use long brush can only about wipe, single-track motion institute causes, sometimes the writing on the blackboard does not need full polishing, and prior art does not all reach.

It is strong that the purpose of this utility model provides dust removal ability, and the automaticity height is carried out three orbiting motions, needs to wipe that, just wipes that a kind of electric remote control dust suction scrubbing brush machine.

The technical scheme that realizes the present utility model purpose is to solve like this, comprise 12 volts of dc source devices, the remote controller of a peripheral hardware or hand switch, one along on the blackboard, two minisize tracks of lower edge, four minisize track wheels are inserted on the minisize track, improvements of the present utility model are that the axle of four minisize track wheels is connected with metal shell, connect two interior slide rail roads respectively in the left and right sides of metal shell, rail wheel slides along interior slide rail road, on the interior both sides of balancing stand reach, following two ends are connected with soft fixed strip bar respectively, soft fixed strip bar again with by the splicing of miniature channel-section steel and form inner supporting frame therein and be connected with sliding tray, on inner supporting frame, following two ends are link slot profile shaft wheel respectively, the axial flow vacuum cleaner is housed below the grooved arbor wheel, the base plate of inner supporting frame is provided with screen pack dust storage warehouse box, supporting plate hole and base plate mesh, powder removal device is installed in the bottom of storehouse box, the two ends of the porose brush of closed revolution are enclosed within respectively on the grooved arbor wheel, metal derby is equipped with at its back side, metal derby is embedded in the sliding tray and slides, the axle of stepper motor is connected on the metal shell, reducing motor is connected with inner supporting frame, driver slot profile shaft wheel rotates, and drive the revolution of the porose brush of closed revolution, a driving device for step-by-step left side, right motion, another stepper motor is by on the steel strip dynamic balancing frame, following motion, the axle of balancer 18 is fixedlyed connected with metal shell 4, establish an extension spring in the balancer 18, extension spring one end is fixed on the axle, and the extension spring other end is connected with balancing stand by rope.

The utility model compared with prior art, it is by a driving device for step-by-step side-to-side movement, another stepper motor driven equilibrium frame is done upper and lower motion, driving the porose brush of closed revolution by reducing motor driver slot profile shaft wheel and do gyration, is a device that has three tracks can move simultaneously.Therefore, this device has rational in infrastructure, remote-controlled or manual operation, movement velocity is fast, but the entire plate face is wiped, also can wipe arbitrarily by local plate face, the characteristics that all kinds of single face blackboards such as suitable wooden, cement, glass use, entire mechanism belongs to soft friction, totally-enclosed, no dust pollution device, brush is changed convenient, and cost is low, the advantage of rub resistance.

Below in conjunction with accompanying drawing content of the present utility model is described further:

Fig. 1 looks generalized section for master of the present utility model;

Fig. 2 is the schematic side view of Fig. 1;

Fig. 3 is the inner supporting frame slideway of Fig. 1, base plate mesh schematic diagram;

Fig. 4 is the porose brush schematic rear view of the closed revolution of Fig. 1.

Referring to Fig. 1, shown in Figure 2, four minisize track wheels 1,19 axle is connected with metal shell 4, connect two interior slide rail roads 5 respectively in the left and right sides of metal shell 4, rail wheel 7 is 5 slips along interior slide rail road, on the interior both sides of balancing stand 8 reach, the lower end respectively with soft fixed strip bar 11,17 connect, soft fixed strip bar 11,17 again with by the splicing of miniature channel-section steel and form inner supporting frame 20 therein and be connected with sliding tray 23, on inner supporting frame 20, following two ends are link slot profile shaft wheel 9 respectively, 15, axial flow vacuum cleaner 10 is housed below the grooved arbor wheel 9, screen pack dust storage warehouse box 12, powder removal device 14 is installed in the lower end of storehouse box.The axle of stepper motor 2,3 is connected on the metal shell 4, reducing motor 13 is connected with inner supporting frame 20, driver slot profile shaft wheel 15 rotates, and drive 24 revolutions of the porose brush of closed revolution, be wound with the left and right motion of wire drive on the axle of stepper motor 2, be wound with steel cable 6 on the axle of stepper motor 3 and drive balancing stand 8 upper and lower motions, the axle of balancer 18 is fixedlyed connected with metal shell 4, establish an extension spring in the balancer 18, extension spring one end is fixed on the axle, and the extension spring other end is connected with balancing stand 8 by rope.

Shown in Figure 3, inner supporting frame 20 is to be spliced by two channel-section steels, and two notches of channel-section steel splice relatively, forms a groove in the middle of it, and this groove is a sliding tray 23, is provided with supporting plate hole 21 and base plate mesh 22 on the base plate of inner supporting frame 20.

Shown in Figure 4, the back side of the porose brush 24 of closed revolution, center fixed has the metal derby 16 of interruption, and it is embedded in the sliding tray 23, prevents porose brush 24 deflections, is provided with a plurality of air suction openings on whole brush.

The side-to-side movement of above-mentioned said device, it is that the rope that fixedly has spring at the blackboard two ends carries out transmission around stepper motor 2 arbor wheels, is fixed on two leads at blackboard two ends, gives stepper motor 2 by brush with power delivery.
