Description

The dustless blackboard erasing machine of manual multifunctional

The utility model relates to the teaching Health blackboard wiping that school teaches and uses, and refers to the dustless blackboard erasing machine of a kind of manual multifunctional especially.

In background technology, following several blackboard eraser is arranged at present: 1. plank felt blackboard eraser, structure is to make matrix by 120 * 70 * 10 plank, above gluing felt cloth make the manual blackboard brush that uses, its weak point is that the expense that back and forth erases the board back and forth is artificial, and efficient is low, dust from flying, especially dust is more near the blackboard, causes very big harm for teachers and students' health; In the primary school, little chap student can't scrape along blackboard top, is stepping on stool and wiping, and Chang Yi causes tumble injury student's accident to take place; 2. double-roll type blackboard eraser, its structure is to add interference fit mutually by plastic casing and two blanket rollers to make, its advantage is in design the laying dust device to be arranged, but the pressure of mutual restriction is difficult to regulate between two rollers, because wearing and tearing two rollers in the use do not have the effect that erases the board, the dust in the laying dust device is taken advantage of a situation and is outwards flown upward along with the rotation of two rollers, because this brush shell is made of plastic, the wearing and tearing of double-roller enlarge axis hole, just can't repair in case this phenomenon occurs.Say that to a certain extent this double-roll type blackboard eraser is not so good as plank felt blackboard eraser, the cost height, service life is short; 3. electric blackboard eraser, its structure is made up of plastic casing, direct current generator, air draught leaf, filter screen, the bonding felt of enclosure.Its using method is the same substantially.Undesirable part has six, one, and cost exceeds several times, and the 2nd, often to change battery, form investment repeatedly, the 3rd, bristle, felt is changed difficulty, and the 4th, shell is fragile, and the 5th, manipulate and be difficult to grasp, the 6th, do not alleviate teachers and students' labour intensity; 4. the outward appearance of dust-free chalk is identical with existing chalk, when erasing the board, micro-little dust is only arranged, but need to be equipped with a kind of plastic blackboard of special use, the method for scouring is that the blackboard eraser that will foam be housed soaks water, cleans along the plate face then, every operation once also needs water flush away powder, so, has relatively increased teachers and students' labour intensity, specification requirement is loaded down with trivial details, the complexity that conforms cooperates blackboard single, more time-consuming, inefficiency, the north difficult use the in winter.

The purpose of this utility model is the weak point that overcomes in the above-mentioned background technology, develops the dustless blackboard erasing machine of a kind of manual multifunctional, realizes erasing the board armstrong's patentization, the control dust polluting environment, and protection teachers and students health is increased work efficiency, and reduces labour intensity.This is the applicant after development driven dust-free blackboard erasing machine and the manual dustless blackboard erasing machine of developing.

Technical solution of the present utility model is as follows:

Form by supporting running gear, brush body device 9 and dust exhaust apparatus 7, be characterized in, in the supporting running gear, the stroke pulley 1 that housing 10 assembles with support 2 up and down, with be fixed on blackboard about in the of 11 orbit 12 do supporting and operation cooperates, pull bar 4 is assembled in housing 10 outsides; In brush body device 10, adjustable up and down support column 25, brush body orbit 23, the steel spring plate 24 that can do arc swing all are assemblied in housing 10, assembling is with the push rod 27 of spring 26 on the stay pipe 25, level movably adds a rubber slab 19 and felt 20 with the screw assembling on the angle steel 34, level movably push rod 27 is exerted pressure to angle steel 34 by the spring steel plate (24) of swing, and 11 cooperations erase the board; In dust exhaust apparatus 7, the assembling power set drive fan blade 17 rotations on its housing 10, do air draught and cooperate, and aspiration channel 18 ports on the housing 10 are filter cloth 16 fixedly, make filter dirt and cooperate.

Technical solution of the present utility model also comprises:

Assembling clutch operation handle 21 on the pull bar 4 outside housing 10, the other end of assembling clutch backguy 22 is connected with brush body angle steel 34 through the backguy pipe on the handle 21, makes brush body and cooperates with blackboard 11 clutches.

In the power set of dust exhaust apparatus 7, fan blade 17 and wind sucting tube 18 directly are assemblied on the motor 15, filter cloth 16 belows of wind sucting tube 18 port assemblies are control of dust spaces, the cleaning lid 5 that assembling can be opened on the housing 10 of filter cloth 16 belows, assembling is rewritten and is wiped head straw 6 on dust suction housing 10, and the hand-held small blackboard of suction pipe 6 port assemblies is wiped.

In the power set of dust exhaust apparatus 7, assembled shaft assembly 31 on the housing 10, the friction pulley 28 of axle assembly 31 ends assembling is made frictional drive power with stroke track 12 and is cooperated, fan blade 17 on accelerated band moving axis assembly 31 rotates, doing air draught cooperates, the cooperation of exerting pressure of hinged compression spring plate 35 compressing friction pulleys 28 is assembled the push rod 33 compressive pressure latch plates 35 that have spring and is adjusted pressure fitted on the housing 10 on the housing 10.
