Abstract

The utility model discloses a rotary automatic dust collecting blackboard, which relates to a teaching blackboard. The utility model is mainly composed of a removable plastic rubber blackboard which is expanded tightly on a speed changing drum and a corresponding wiping dust collector. The utility model replaces a traditional blackboard and can prevent dust flying in classroom effectively.

Description

Rotary automatic dust-reducing blackboard

Automatically dedusting rotary type blackboard replaces traditional teaching blackboard with special frame mode.

The purpose of this utility model is that a kind of novelty and the practical automatic dedusting rotary type blackboard that combines will be provided.Without manual wipping, the situation of dust from flying in the classroom of changing over.Can carry out continuously or slowly rotate discontinuously along with teaching process, and the content of removing on the blackboard automatically to be write, both protect the cleaning of classroom environment; Guaranteed that also teacher student's is healthy.

This is dedusting rotary type blackboard automatically, is by housing; Rotary Blackboard; Automatically wiping formula and automatic dust removal part are formed.Similar just four limits with normal blackboard of profile are many individual housing, there is the several Control switch front.

The rotary type blackboard is made by dark plastic, rubber.

The purpose of this utility model is achieved in that Rotary Blackboard is by the down roller that is tightened in the dark plastic, rubber plate on the framework, by Motor Drive, realizes the slow rotation of blackboard by decelerator.

Wiping partly is that a dedusting of plate face and a vibration deciliter handle are beaten to wiping position, is made up of felt calender, hairbrush and motor, and the moving direction of its rotation direction and blackboard is opposite.Felt calender and hairbrush are driven by chain by motor and realize.Oscillating component is that a dedusting and a vibration deciliter handle are beaten to vibration position, is finished by dedusting motor and vibrator, carries out the hairbrush dedusting separately.The dust that vibration brush falls falls in the airtight dust compartment and regularly harrows its removing with ash disposal.

This automatic dedusting rotary type blackboard concrete structure is provided by following examples and accompanying drawing thereof.

Now be described with reference to the accompanying drawings the course of work of its device.

Automatically dedusting rotary type blackboard mainly comprises blackboard inner support (1), spring (2), hairbrush (3), hairbrush inner support (4), vibrator and dedusting mechanism (5), driving-chain (6), dedusting motor (7), dedusting rake (8), dust compartment (9), plastic, rubber blackboard (10), the plate face rotates and dedusting switch (11), general supply key switch (12), speed change cylinder (13), Rotary Blackboard motor (14), power supply box and plastics housing (15), dedusting of plate face and vibrator deciliter handle (16) is formed.

When needs rotated plastic, rubber blackboard (10), by speed change cylinder (13) Rotary Blackboard motor (14), the plate face rotated and dedusting switch (11) is controlled, and the plate face can be moved up by the arrow direction.

Wiping partly is that dedusting of plate face and vibrator deciliter handle (16) are beaten to wiping position, is driven by dedusting motor (7), finishes by vibrator and dedusting mechanism (5), cooperates hairbrush (3) to rotate and carries out wiping.

Oscillating component is that dedusting of plate face and vibrator deciliter handle (16) are beaten to vibration position, drive by dedusting motor (7), finish by vibrator and dedusting mechanism (5) spring (2) and dedusting switch (11), separately the vibration of the dust on the hairbrush (3) is come off, dust falls in the dust compartment (9), regularly removes with dedusting rake (8) at last.

It is fixed that the velocity of rotation of its blackboard can be come according to the speed of giving lectures, and its speed can fix on 6 meters/minute and be advisable, and the size of blackboard depends on the needs.

Claims

1, automatic dedusting rotary type blackboard, its device mainly contains plastic, rubber blackboard (10) and corresponding wiping vibrator and dedusting mechanism (5) composition of swelling between the speed change cylinder (13) of two garden cylindricalitys, it is characterized in that speed change cylinder (13) directly links to each other with rotary electric machine (14); The wiping dedusting drives hairbrush (3) by driving-chain (6) and finishes.The translational speed of its blackboard is 6 meters/minute.

2, according to the described device of claim 1, its feature plastic, rubber blackboard (10) swelling links to each other with driving motor (14) between speed change cylinder (3); Driving-chain (6) drives hairbrush (3) and carries out wiping.

3,, it is characterized in that plastic, rubber blackboard (10) links to each other with speed change cylinder (3) according to the described device of claim 1; Driving-chain (6) drives attitude hairbrush (3) and rotates.
