State.
Referring to Fig. 9, Figure 10, when certainly walking dust suction and using, this fuselage 10 is walked on smooth ground A, due to this round brush group
The weight of part 20 itself, makes this downward swing of pivotal arm 41, and makes the smooth ground A of bottom surface laminating of this dust sheet 62, in this
During the smooth ground A that fuselage 10 passes through, this round brush 21 coordinates this dust sheet 62 to sweep dust and chip, now, the ash swept
Dirt and chip are sucked in dust-collecting box 11 by this dust exhaust apparatus 12.Refer to Figure 11, when running into slope ground B, due under this
Lid 60 this dust sheet 62 fit this slope ground B up, this dust sheet 62 by slope ground B pressure upwards, therefore,
And push this round brush assembly 20 upwards, this pivotal arm 41 upwards swing, meanwhile, this flexible couplings 70 is also because of this round brush assembly
20 impacts upwards and produce slight deformation, this pivotal arm 41 above-mentioned coordinates this flexible couplings 70 to be able to ensure that this dust sheet 62
Keep the state of laminating slope ground B.
Should be noted that, the present invention upwards walks in slope ground B example with this fuselage 10, and this fuselage 10 also can walk in tiltedly
B is downward for face, hillside fields.
It is noted that slope ground B is a kind of walking disorder, at this as a example by slope ground B, it is not limited thereto,
When walking in protruding ground, the present invention is also up to identical effect.
From the foregoing, it will be observed that the attainable effect of the present invention is: solve in prior art and make this rolling brush rack about earth bulging
Unit root edge cannot fit tightly ground, causes cleaning the affected problem of effect, the present invention except passing through in addition to obstacle terrain,
When this rolling brush rack 30 is by under External Force Acting, due to this pivotal arm 41 can upper and lower swing, therefore, this collection of this rolling brush rack 30
Dirt sheet 62 can keep omnidistance laminating ground, to promote the effect cleaned.
