Dynamic wiping roller 4, the bottom of bar shaped blackboard eraser 3 are provided with horizontally disposed support dirt roller 5, and the support dirt roller 5 is upward close to the surface of blackboard 1
Rotate, wiping roller 4 and support the dirt roller 5 is hollow, and surface is provided with bristle and air suction opening, and wiping roller 4 and support the dirt roller 5 is logical
Cross hose 7 and be connected with being arranged on the dust catcher 6 of the side of blackboard 1.
The technical program can be further optimized for, and the bar shaped blackboard eraser 3 is provided with dust board away from the side of blackboard 1.
Can also further it be optimized for, the downside of support dirt roller 5 is provided with support dirt set.
Compared with prior art, the utility model is practical, reliable, conveniently, and blackboard wiping effect is good, and speed is fast, and dust is few.

Fig. 1 is the utility model overall structure diagram；
Wherein：1st, blackboard；2nd, slide rail；3rd, bar shaped blackboard eraser；4th, roller is wiped；5th, dirt roller is held in the palm；6th, dust catcher；7th, hose.
Embodiment
The technical program is described in detail with reference to Fig. 1：
The utility model proposes a kind of rolling type blackboard eraser, including blackboard 1, the blackboard is provided with slide rail in both sides about 1
2, bar shaped blackboard eraser 3 is provided between slide rail 2, the bar shaped blackboard eraser 3 includes the wiping rollers 4 of two relative rotations, the bottom of bar shaped blackboard eraser 3
Horizontally disposed support dirt roller 5 is provided with, the support dirt roller 5 is rotated up close to the surface of blackboard 1, wiping roller 4 and support the dirt roller 5
It is hollow, surface is provided with bristle and air suction opening, and wiping roller 4 and support the dirt roller 5 is by hose 7 and is arranged on blackboard
The dust catcher 6 of 1 side is connected.In addition, the bar shaped blackboard eraser 3 is provided with dust board away from the side of blackboard 1.It is further, described
