Abstract
The utility model discloses a blackboard eraser with a dust removing function, which comprises a large eraser component and a small eraser component installed on a same blackboard eraser frame. The blackboard eraser frame engages with the racks installed on a blackboard bracket via gears and is driven by a motor I, the gears and the racks, resulting in horizontal motion of the blackboard eraser on the surface of a blackboard. A large hairbrush carries out horizontal motion while conducting small-range vertical motion under the driving of conical gears for erasing a large area of letters written with a chalk on the entire blackboard or half side of the blackboard. A small hairbrush carries out auto-gyration while rapidly conducting vertical motion under the driving of a motor II, a reel, a pull wire and a guide wheel and horizontal motion under the driving of the motor I, the gears and the racks for erasing a small area of letters written with a chalk, such as a letter, several letters or a line of letters. The large hairbrush and the small hairbrush can be used alternately and are controlled by an electromagnetic chuck. The large hairbrush is mounted on a suction box, and dust discharge pipes are mounted in the inner cavity of the suction box and are connected with a dust collector outside the blackboard eraser via a hose to suck all dust.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3: a kind of blackboard eraser with dedusting function comprises blackboard support 1, blackboard 3, is arranged on the blackboard eraser in blackboard 3 the place aheads.Described blackboard eraser is made up of big blackboard eraser assembly 4 and platelet brush assembly 5 two parts, and is installed in parallel on the scrubbing brush framework 6; Described scrubbing brush framework 6 is a rectangular frame, and the bottom is provided with road wheel 7, and road wheel 7 is connected with guide rail 8 on being installed in blackboard support 1.Two axle 4-7 and shaft with key way 5-4 that be arranged in parallel are vertically mounted on respectively on the scrubbing brush framework 6 by bearing 4-5, and its axis 4-7 is connected with big blackboard eraser assembly 4, and shaft with key way 5-4 is connected with platelet brush assembly 5; Described axle 4-7 and shaft with key way 5-4 two ends are provided with gear 4-6 respectively, and gear 4-6 is meshed with tooth bar 2 on being installed in blackboard support 1.Axle (4-7) upper end is connected with motor I 4-4.
Described big scrubbing brush assembly 4 comprises: suction box 4-1, dust flue 4-2, big hairbrush 4-3, cam disc 4-13, magnechuck 4-8.Described suction box 4-1 is totally-enclosed casing, and cabinets cavity is installed dust flue 4-2, and dust flue 4-2 is connected by the outer dust catcher of flexible pipe and machine; The dust catcher outer with machine is connected; Suction box 4-1 faces big hairbrush 4-3 is installed on the wallboard of blackboard one side, and makes passage, and opposite side is installed cam disc 4-13.Described cam disc 4-13 is connected with axle 4-7 by splined shaft I4-12, bevel gear width of cloth 4-11.Magnechuck 4-8 is connected with scrubbing brush framework 6 by fixed plate I 4-14, bracket I 4-10.
Described platelet brush assemblies 5 comprises: the motor II 5-1 that hairbrush body 5-8, small brushes 5-9, magnechuck 4-8 and drive plate brush assemblies 5 move up and down.Described hairbrush body 5-8 is a disc, and a side is installed small brushes 5-9, and opposite side is connected with shaft with key way 5-4 by splined shaft II5-6, bevel gear width of cloth 4-11.Magnechuck 4-8 is connected with bracket I I5-5 by fixed plates II 5-7; Bracket I I5-5 is connected with the bevel gear width of cloth (4-11), is connected with motor II 5-1 by backguy 5-3, guide wheel 5-10, reel 5-2 simultaneously; Described motor II 5-1 is installed in the top of scrubbing brush framework 6; Described guide wheel 5-10 is installed in the bottom of scrubbing brush framework 6.
When needs were wiped whole blackboards or the large-area letter written with chalk in the left and right one side of blackboard, starter motor I4-4 drove scrubbing brush framework 6 move left and right by axle 4-7, gear 4-6, tooth bar 2, makes big hairbrush 4-3 be positioned at the position that should wipe.Operate the magnechuck 4-8 on the big scrubbing brush assembly 4, magnechuck 4-8 outage, suction box 4-1 moves to left under the effect of spring 4-9, big hairbrush 4-3 presses blackboard 3, axle 4-7 drives cam disc 4-13 motion by bevel gear width of cloth 4-11, splined shaft I4-12 simultaneously, cam disc 4-13 drives suction box 4-1, the big upper and lower reciprocally swinging of hairbrush 4-3, and big hairbrush 4-3 just can wipe all or a side blackboard.After having wiped, 4-8 send electricity to magnechuck, compression spring 4-9, and big hairbrush 4-3 breaks away from blackboard 3, and cam disc 4-13 and splined shaft I4-12 break away from simultaneously, and big hairbrush stops to swing up and down, and energy savings reduces wear, and improves service life.
When needs are wiped some on the blackboard, several words or certain delegation word, magnechuck 4-8 on the operation platelet brush assembly 5, small brushes 5-9 presses blackboard 3 under the effect of spring 4-9, motor I drives small brushes 5-9 move left and right, motor II is by reel 5-2, backguy 5-3, upper and lower the moving of guide wheel 5-10 pulling small brushes 5-9, can wipe a word, several word or delegation's word of optional position on the blackboard 3, convenient and swift.
When big hairbrush assembly 4 was worked, dust entered suction box 4-1 by pore, and dust flue 4-2 is connected by the dust catcher outside flexible pipe and the machine, and dust is discharged.Because dust catcher is the principle work by the axle vacuum, and with the dust collection of discharging, can not be discharged in the atmosphere, good dedusting effect is easy to operate.
