Description
Technical field
The utility model is suitable for lathe guard technology field, especially relates to a kind of novel closed-type from removing gray device of chalk.
Background technology
China numerous teachers and students live in the chalk dust after blackboard wiping every day, cause many covert harms.Statistical analysis shows, and the blackboard eraser dirt that rubbed in removing blackboard process only accounts for 10%, and the dust from flying of the dust from flying and blackboard eraser deashing process that are accumulated in blackboard eraser surface accounts for 90%, and clearly, to blackboard eraser accumulating dust, to carry out dedusting should be key point.In the last few years, relevant scientific worker attempted to improve valuably the blackboard in traditional blackboard-blackboard eraser-chalk framework and composition, blackboard eraser, had occurred many research and development imaginations and design, as electric blackboard eraser, dust-free blackboard and dust-free chalk etc.But and could not really promoted on the market, trace it to its cause, mainly contain that price is high, efficiency of dust collection is low, practicality and technically to organically combine, environmental protection and energy saving aspect is short of to some extent etc., and reason causes.
Utility model content
For overcoming the problems referred to above, the utility model adopts following technical scheme:
A kind of novel closed-type is from removing gray device of chalk, comprise spring, skewed slot and outer container, be provided with spring below the upper plane of outer container, the lower end of spring is provided with fixed black board wiping device, and the bottom right angle place of outer container is provided with two ash collecting box, the middle part of two ash collecting box is provided with motor base, the upper end of motor base is equipped with motor, and the outside of motor is provided with cam, and the upper end of cam is provided with flat-face follower, the upper end of flat-face follower is provided with pressure ram, and the lower end of pressure ram is provided with skewed slot; Be provided with handle on the upside of the left hand external of outer container, downside is provided with start button, and right upper portion is provided with hinge.
Described outer container is cuboid.
Described flat-face follower is provided with hole.
The utility model has the advantages that: the problem fundamentally solving classroom dust pollution, ensured the working and learning environment of teachers and students, improve efficiency of teaching, also protect the impact of various educational technology equipment from dust simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of novel closed-type is from removing gray device of chalk, comprise spring 1, skewed slot 2 and outer container 5, spring 1 is provided with below the upper plane of outer container 5, the lower end of spring 1 is provided with fixed black board wiping device 6, the bottom right angle place of outer container 5 is provided with two ash collecting box 3, the middle part of two ash collecting box 3 is provided with motor base 9, the upper end of motor base 9 is equipped with motor 10, the outside of motor 10 is provided with cam 4, the upper end of cam 4 is provided with flat-face follower 8, and the upper end of flat-face follower 8 is provided with pressure ram 7, and the lower end of pressure ram 7 is provided with skewed slot 2; Be provided with handle 12 on the upside of the left hand external of outer container 5, downside is provided with start button 13, and right upper portion is provided with hinge 11.
Described outer container 5 is in cuboid.
Described flat-face follower 8 is provided with hole.
Work process is as follows:
By fixing on the securing means for the blackboard eraser with chalk dust, press the button, actuating motor 10, cam 4 is made to drive flat-face follower 8, under the effect of cam 4 eccentric throw, the blackboard that pressure ram 7 up and down reciprocatingly extrudes blackboard eraser is continuous, under the cushioning effect protection of spring 1, ensure that blackboard eraser can not be squeezed out device, also play the effect of good damping and minimizing noise simultaneously; Chalk dust shrinks effect of inertia because pressure ram 7 extrudes and falls down, and by the hole among flat-face follower 8 upper flat plate and then drop on skewed slot 2, is slipped in the ash collecting box 3 in device, can not be diffused into whole classroom.Finally clear up ash collecting box 3, this completes the whole ash disposal process to blackboard eraser.Dust to be collected reach a certain amount of after, take out ash collecting box 3, chalk dust poured in polybag, utilize as non-combustible, callable material.
