Abstract

The utility model relates to an electric chalk dustless teaching board which belongs to the teaching device. The utility model adopts an ABS sheet as a board surface, an angle steel is used as a supporting tank bracket, the board surface is sheathed on a drive shaft and a driven shaft, driving wheels are respectively linked with a motor and the drive shaft by V-belts, the lower end of a frame is also provided with a water tank, a round brush shaft is connected to the water tank, the round brush shaft and the bottom margin of the board surface form a sliding friction, a group of fixed hair brushes are arranged in the water tank, the fixed hair brushes and the round brush form a friction contact, through the linkage of the V-belts, the whole process can be controlled by an electric control switch, when the board surface moves, writing can be automatically erased by the round brush, the dust is brushed off by the frictional contact of the round brush and the hair brushes, the dust falls into the water tank and is precipitated, the dust nuisance is avoided, the environment is protected, and the health of teachers and students can be protected.

Description

The driven dust-free teaching board

The utility model belongs to the teaching equipment class, particularly be a kind of driven dust-free teaching board.

In teaching, generally adopt traditional mode that blackboard is fixing on the wall, and need to clean writing by manpower, dust from flying often to occur, problems such as contaminated environment, can endanger the healthy of teachers and students for a long time, pupil Ze Yin can't reach blackboard, need step on stool sometimes and wipe, tumble injury takes place easily, very dangerous.

The purpose of this utility model is to provide a kind of teaching use of being convenient to, and the plate face is capable of circulation to be moved, automatically the driven dust-free teaching board of erasing writing.

The technical solution of the utility model is the driven dust-free teaching board that is made of framework, plate face, motor, electric-controlled switch and drive etc., wherein the plate face is a socket type, be sleeved on driving shaft and the driven axle, drive constitutes transmission with motor and driving wheel respectively and pays, be characterized in: the lower end of framework also is provided with a tank, roller brush shaft is connected on the tank, and constitute sliding friction with the base of plate face and pay, one group of fixedly hairbrush is arranged in the tank, and contact with round brush friction, the scroll wheel of round brush and the transmission of drive formation are paid.One side of plate face is equipped with electric-controlled switch.

The utility model has the advantages that the mode of utilizing electric-motor drive moves the circulation of plate face; round brush rotates and wipes writing simultaneously; the round brush that hairbrush will be wiped full dust again scrubs clean; dust falls into precipitation in the water tank; avoid dust from flying; the protection environment, useful teachers and students are healthy, are a kind of comparatively desirable teaching equipments.

Provide below in conjunction with drawings and Examples.

Fig. 1 is a structural principle schematic diagram of the present utility model.

As shown in Figure 1, the utility model is by framework 9, plate face 8, motor 7 and drive 3,4 formations such as grade, wherein plate face 8 is socket type (can select the ABS sheet material for use), be sleeved on driving shaft 1 and the driven axle 6, drive 3,4 constitute transmission with motor 7 driving shafts 1 by the V belt interlock respectively pays, especially also be provided with a tank 12 that water is housed in the lower end of framework 9, round brush 10 is coupling on tank 12, and with the base sliding friction of plate face 8, fix one group of hairbrush 11 in the tank 12, hairbrush 11 can be soaked in water with round brush 10 frictions and contact, the scroll wheel 5 and the drive 3 of round brush 10 pass through belt transmission, whole process can be utilized motor 7 to drive driving shaft 1 by drive 3 when connecting power supply and carry out running work with scroll wheel 5 by electric-controlled switch 13 controls, and 8 circulations of plate face are moved in operation process, round brush 10 automatic erasing writings, round brush 10 contacts with hairbrush 11 frictions, and dust is washed from round brush 10, falls into tank 12 precipitations.
