Abstract
The utility model relates to a complete automatic cleaning type blackboard. The utility model comprises a blackboard, a machine frame and two parallel lead rails which are fixed in the upper and lower ends of the blackboard; the machine frame is positioned between the two lead rails of the two ends of the roller; the blackboard brush is fixed with the machine frame; the utility model can move transversely and rotatablely driven by the motor; and the bottom end of the blackboard brush is connected with a cleaner. The utility model overcomes the disadvantages of the prior blackboard which wastes time and labor and has dust; the utility model has automatic letter brush function and dust absorbing function; and the utility model can improve the working environment of the teacher and enhance the teaching efficiency.
Description
The utility model relates to the realia technical field, provides a kind of and can wipe word automatically, blackboard that again can dust suction.
Existing blackboard is not with dust exhaust apparatus, literal on the blackboard is by manually wiping wiping with blackboard, and blackboard eraser commonly used is to be made of the brush body that has bristle, utilize bristle erasing back and forth on the blackboard of chalk writing, chalk writing is come off from blackboard, reach the purpose of eliminating chalk writing on the blackboard, thereby thisly waft wine on the blackboard surface with the dust under the blackboard brushing, make the teachers and students that often erase the board be subjected to the hardship of dust pollution deeply, influence healthyly, manually erase the board simultaneously, physical demands is big, efficient is low, influences the efficient of giving lessons.
The purpose of this utility model be to provide at the defective of prior art a kind of easy to use, can thoroughly eliminate dust pollution, replace the automatic dust-absorbing formula blackboard that manually erases the board.
Goal of the invention of the present utility model is achieved by the following scheme: this automatic dust-absorbing formula blackboard, comprise blackboard, frame and be fixed on two closed slides on the upper and lower both sides of blackboard panel, frame is located between two guide rails by the turning rolls that is fixed on its two ends, being fixed on motor on the frame drives an end roller by transmission mechanism I and walks in the guide rail to drive frame and laterally move, frame is provided with the blackboard brush that is driven by transmission mechanism II by motor, the lower end of blackboard brush is connected with dust catcher, is provided with contactor in the appropriate position of blackboard.And described transmission mechanism I by decelerator, be fixed on the small belt pulley on the reducer output shaft, the big belt pulley that is connected with small belt pulley by belt constitutes, big belt pulley is fixed on the roller shaft, roller and big belt pulley are fixed.And described transmission mechanism II is the driving-chain that belt pulley and nylon tape by several arranged in dislocation constitute, described blackboard brush is by constituting with fixing several brush dishes of belt pulley, the brush dish outside is provided with the retaining air ring, and brush disk center blast pipe communicates with dust catcher through air flue.
The utility model compared with prior art, owing to have automatic blackboard brush and automatic dust absorption device, automatically the chalk writing on the erasing blackboard and the dust that wipes sucked in the dust catcher, thus have laborsaving, save time, improve the efficient of giving lessons, dust suction thoroughly, advantages such as pollution abatement fully.
Description of drawings.
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A cutaway view (amplification) of Fig. 1;
Fig. 3 is the B-B cutaway view of Fig. 1;
Fig. 4 is that the C of Fig. 3 is to view.
Embodiment to the utility model is described further below in conjunction with accompanying drawing:
Shown in Fig. 1-4, this automatic dust-absorbing formula blackboard mainly is made of blackboard (not shown), guide rail 1, frame 4, single-phase AC motor 15, transmission mechanism I, II, blackboard brush and dust catcher 5 etc.Wherein two guide rails 1 are separately fixed at the upper and lower both sides of blackboard panel and are parallel to each other.Frame 4 is a tower structure, is stamped a cover plate 8 on it.Frame 4 is located between two guide rails 1, and roller 19 all is equipped with at two ends, and roller 19 is located on the guide rail 1, can walk on the guide rail 1 under motor 15 drives, and frame 4 then drives the lower edge blackboard surface at roller 19 and laterally moves.
Transmission mechanism II is made of the belt pulley 3 and the driving-chain that constitutes of nylon tape 2 of several arranged in dislocation in frame 4, and wherein main pulley 7 is fixed on the output shaft 6 of decelerator, and remaining belt pulley 3 is separately fixed on the blast pipe 14 that communicates with air flue 13.
Blackboard brush constitutes by being fixed on several brush dishes that can contact with the blackboard surface on the blast pipe 14, between brush dish and the belt pulley 3 bearing 12 is installed, and the brush dish is threaded with belt pulley.And the brush dish constitutes one by the sponge 10 of disk body 11 and outsourcing flannelette, and sponge is pasted on the annular groove place of brush dish.The brush dish outside is provided with retaining air ring 9.
Contactor and dust catcher 5 can be separately fixed at the appropriate position of blackboard or body of wall, and dust catcher 5 joins by a bellows and the air flue connecting plate 20 that is fixed in the frame bottom.
During use, as long as indicate according to the switch direction, press touch switch, electric motor starting makes frame one end move to the other end through transmission mechanism I, through transmission mechanism II each the brush dish in the blackboard brush is rotated simultaneously, laterally mobile and rotatablely moving of brush dish by frame smeared down the chalk writing on blackboard surface, dust under smearing again because electric motor starting the time, dust catcher is also started working, thereby with the brush dish sucks in the dust catcher fully through blast pipe, air flue, bellows.In any position, will stop when pressing stop key, when moving to another end points, frame also can stop automatically, and respectively there is a travel switch effect termination, presses rightabout key frame and can finish brush suction work to moving in the other direction again.
In addition, the startup that this automatic dust-absorbing formula blackboard also can adopt remote control to control the walking of blackboard brush, erasing, dust suction stops, and reaches the purpose that the examination blackboard is wiped in Remote Control Automatic dedusting.
