Task of the present utility model provides a kind of fully automatic blackboard cleaning machine.Rotate, replace manpower to erase the board clearly with the driven by motor hairbrush with machinery; Protective cover and dust catcher also are housed on it, disperse to prevent dust, not only health but also can alleviate classmates' burden guarantees that teachers and students' is healthy.
Primary structure of the present utility model is that mobile motor 1,2 and electric rotating machine 4 are contained on the mobile framework 3, mobile thick stick frame 3 is fixed on the fixed frame 9 by four ball bearings 5,6,7,8, and fixed frame is fixed on the wall by four bolts 10,11,12,13.Mobile framework 3 can be by the move left and right on the fixed frame 9 that is rotated in of mobile motor, and the rotation of mobile motor and electric rotating machine is controlled by power distribution equipment.14 is blackboard.On the mobile motor 1,2 gear is housed, with spacing little steel-tooth 15 interlocks.The disk hairbrush is housed on the electric rotating machine, wipes chalk writing by the rotation of disk hairbrush.Protective cover 17 protective covers the inside is housed on the mobile framework 3 dust catcher 16 is housed.
Below in conjunction with accompanying drawing the utility model is done further narration.Accompanying drawing 1 is the front view of " fully automatic blackboard cleaning machine ".Fig. 2 is the left view of " fully automatic blackboard cleaning machine ".Fig. 3 is the circuit diagram of cleaning machine.Fig. 4 is the cross-sectional view of stopping means.Fig. 5 is the left view that electric rotating machine is connected with the disk hairbrush.Among the figure: 1,2 is mobile motor.The 3rd, mobile framework.The 4th, electric rotating machine.5,6,7,8 is four ball bearings.The 9th, fixed frame.10 11 12,13 is four bolts.The 14th, blackboard.The 15th, spacing little steel-tooth.The 16th, inhale sharp device.The 17th, protective cover.The 18th, spacing starting point.The 19th, spacing terminal point.The 20th, the disk hairbrush.The 21st, wall.The 22nd, binding nut.
Fixed frame 9 is to be made by smooth steel cylindrical tube, and wherein starting point 18 has jagged little steel-tooth below terminal point 19, its cross section as shown in Figure 4, top is steel pipe, the bottom is little steel-tooth.Steel tube surface is smooth to be convenient to mobile framework 3 and to slide thereon, and mobile framework 3 is connected by four ball bearings 5,6,7,8 with fixed frame 9.
Turn clockwise during mobile motor 1 energising, be rotated counterclockwise during mobile motor 2 energisings.Mobile motor 1,2 all is fixed on the mobile framework 3, when mobile motor 1 energising, will drive mobile framework is moved to the left, make the disk hairbrush on the mobile framework also be moved to the left, when mobile motor 1 has just been crossed starting point 18, gear on the mobile motor 1 and little steel-tooth break away from, and mobile framework just stops to move to left, and just is parked in the left side of blackboard; When mobile motor 2 energising, the gear on the mobile motor can with little steel-tooth interlock, drive mobile framework and move right, when mobile motor 2 had just been crossed terminal point 19, mobile framework just just was parked in the blackboard right side.Little steel-tooth plays position-limiting action.
4 places are 6 (as required, number can change) electric rotating machines among Fig. 1, and the disk hairbrush is housed under it.Fig. 5 is its left view, the 4th, electric rotating machine, the 20th, be stained with hair or anti-rubbing cushion on the circular plank, be similar to the disk hairbrush of blackboard eraser, hair or anti-rubbing cushion and blackboard produce friction, to wipe chalk writing, the disk hairbrush is contained in the rotating shaft of motor, can change new after hairbrush is worn.Electric rotating machine all is fixed on the mobile framework, the rotation direction of electric rotating machine shown in arrow among Fig. 1, all the turning clockwise of left side, all being rotated counterclockwise of right side.
17 is protective covers among Fig. 2, its shape as shown in Figure 2, its inside is equipped with and is inhaled sharp device 16, absorbs dust granules.
Fixed frame is bolted on the wall by four, and these four bolts are 10,11,12,13 each point places in Fig. 1 respectively, and vertical paper inwards.Fig. 2 is a left view, the 21st, and wall.Cut screw on the screw rod and had 2 binding nuts 22, entreated both sides respectively at wall.
Fig. 3 is the circuit diagram of cleaning machine.K1 is a master switch, and K2, K3, K5 are switch-dividings, and K4 is a single-pole double-throw switch (SPDT), and when connecting mobile motor 1, mobile framework and disk hairbrush are moved to the left; When connecting mobile motor 2, mobile framework and disk hairbrush will move right.When connecting dust catcher 16, dust catcher begins to absorb dust granules.K2, K3, K5 generally are in closure state, and speed regulator does not need frequent change yet, therefore, when operating machine, only need transfer K1 and K4 to get final product.Transfer wire among the figure in the frame of broken lines can be made one spring wire, is hung in below the mobile framework behind the also available moccasin bag.Transfer wire can be contained on the control panel with each element on a left side.For attractive in appearance, if having ready conditions, also fixed frame can be contained within the walls, have only protective cover to be exposed.
