Description
Technical field
The utility model belongs to daily teaching and uses the plant equipment field, relates to a kind of mechanical type blackboard wiping machine, is mainly used in the automatic wiping work to blackboard.
Background technology
Present stage education is seized of consequence and meaning in the national economy of China is produced." Science and technology constitutes a primary productive force " and want to have large quantities of skilled personnel and just be unable to do without education for populous China, is undoubtedly huge in receive an education student's number of school.
Doing " the detailed number of Chinese teenager's population in 2007 " investigation according to Chinese Youth and Teenager Research Center shows, primary school education stage students' number is 10,564 ten thousand people, junior middle school education stage students' number is 5736.19 ten thousand people, senior middle school education stage students' number is 4527.49 ten thousand people, higher education stage students' number surpasses 2,700 ten thousand, that is to say that the whole nation each stage students' sum is about 23527.68 ten thousand people.Student more than 200,000,000 is exactly teacher at accept the education our main Knowledge Source of school, and hard teacher is that media is given us with knowledge-transference with the blackboard.The content that a class gets off on the blackboard can have been wiped and write by teacher, has write the circulation of wiping again back and forth, and teacher is saying that class erases the board has not only been wasted the time but also worsened the environment in the classroom, has reduced teacher's the efficient of giving lessons.
For the trouble of avoiding using blackboard to bring is exactly that teacher avoids using blackboard to use multimedia teaching instead on class as far as possible, adoption of multimedia teaching means is with the obvious advantage, if single use or improper use also have drawback: 1, preparing lessons wastes time and energy; 2, instruction cost is higher; 3, operation is relatively more mechanical; 4, can not generate at random; 5, inconvenient teacher's performance; 6, be unfavorable for comprehensive raising of teachers ' teaching basic training and comprehensive displaying of individual speciality; 7, the imagination space of having blocked the student in a way, the thinking in images that is unfavorable for cultivating the student.8, information content is excessive, accepts or rejects improper easy formation information pollution, influences teaching efficiency.9, too lay stress on form, a presumptuous guest usurps the role of the host easily, and influence is to study and the digestion of the content of courses itself.Perhaps this just multimedia can't replace the reason of blackboard fully.
The utility model content
It is a kind of convenient, fast that the purpose of this utility model is to provide, and the mechanical blackboard wiping arrangement of cleaning disorderly flies in order to the dust that replaces the manual wipping blackboard and prevent from wiping.Utilize this mode to shorten the time that the teacher classroom is wasted because of blackboard wiping greatly, alleviate teacher's labour intensity, the classroom of the having improved teacher efficient of giving lessons.Particularly particularly important concerning the students that is about to participate in college entrance examination, the give lessons raising of efficient of teacher has increased the chip that changes own destiny again to them beyond doubt.Utilize this mode can also avoid the phenomenon that causes chalk powder disorderly to fly because manually erasing the board, improved the air in the classroom, the academics and students can both be worked in a clean comfortable classroom and learn.
The technical solution of the utility model is as follows:
A kind of mechanical type blackboard wiping machine, comprised the outer gimbal support that is fixed at blackboard 25 upper and lowers has been arranged, slide on the outer gimbal support and be provided with wiping arrangement 24, outer gimbal support is by horizontal upper rail 2, vertical upper rail 1, horizontal lower guideway 6, vertical lower guideway 5, described wiping arrangement 24 includes square shell 15, group 10 cogs, lower tooth wheels 14, on the shell 15, the lower end is fixed with wheel carrier 13 respectively, on, be fixed with on the wheel carrier 13 of lower end orthogonal and respectively with horizontal upper rail 2, vertical upper rail 1, horizontal lower guideway 6, the vertical movement of going up that vertical lower guideway 5 fits tightly takes turns 22, on move horizontally the wheel 23, under move horizontally the wheel 20, sagging translation driving wheel 21; Described lower tooth wheels 14 are by pitch wheel f, g, h constitute successively, gear h drives with travel motor 18 and is connected, the power tooth bar 4 of gear f and horizontally set is meshing with each other, the group 10 that cogs is by pitch wheel a, b, c, d, e constitute successively, gear a drives with hairbrush motor 16 and is connected, and gear c, e are fixedlyed connected with rolling hairbrush 8 respectively.
Described rolling hairbrush 8 two ends fixedly have hairbrush fixed cover 17 respectively, hairbrush fixed cover P end margin leaves four hole T1 and is used for installing the screw that connects hairbrush, the sealing of Q end also stays a square aperture T4 to be used for installing the axle T3 of transferring power, in the middle of the axle T3 rolling bearing T2 is installed.
Described two rolling hairbrush 8 outside mask are equipped with inner cover 9, and inner cover 9 adds rubber weather strip 7 with blackboard contact site both sides.
Described blackboard below is provided with dust collection groove 3, and described wiping arrangement shell is provided with shell door 11, and described inner cover is provided with inner cover door 12.
The utility model design independently vertical two guide rails in order to being fixed on the two ends up and down of blackboard, design and installation on the guide rail is a kind of can be along guide rail blackboard wiping arrangement of move left and right stably in the working face parallel with blackboard.Utilize two motor that work alone as power source, one drives work hairbrush quick rotation, and it is mobile lentamente on guide rail that another drives the blackboard wiping arrangement.Rely on the kind of drive of rack-and-pinion to drive the driving rack mobile working that the blackboard wiping arrangement is being fixed along guide rail.The hairbrush of blackboard wiping arrangement is close to the rotation fast of blackboard do with suitable pressure during machine works, and the integral body of blackboard wiping arrangement is mobile slowly.Inner cover prevents that near blackboard and in addition rubber strip sealing chalk powder from disorderly flying.The chalk powder that wipes out drops under the effect of gravity to be done unified the removing and sweeps in the dust collection groove of blackboard lowermost end.Outside the feeder chalk powder in the machine of descending slowly and lightly is cleared up away by machine dust cleaning Hatch Opening bottom.Awaiting orders in the machine that can rest on blackboard one end behind device wiping complete blackboard nearby zone of berthing, does next time and use.
