The invention discloses a
scavenging machine for a classroom. The
scavenging machine comprises a placement board, a sliding chute, a storage battery, support legs, rolling wheels, a fixed column, a dust storage shell, a filtering net, an air suction
pipe, a draught fan, a telescopic
pipe, a dust suction head, a dust feeding cylinder, a dust feeding cavity, a
linear motor, a fixed rod, a
handle, anoutput rod, a fixed block, a first connecting plate, a first pawl, a first
torsion spring, a second connecting plate, a second pawl, a second
torsion spring, a
ratchet wheel, a connecting rod, a
scavenging hairbrush and an electric pushing rod. The scavenging
machine is simple in structure and novel in design, dust on the ground inside the classroom is scavenged into the dust feeding cylinder through the scavenging hairbrush, so that the scavenged ground does not need to be repeatedly scavenged by virtue of the scavenging hairbrush, the ground in the classroom can be cleaned once, the fluctuation of the dust is avoided, the indoor
environmental quality is guaranteed, the scavenging machine is convenient to use, and the scavenged dust can be collected and stored by virtue of the dust storage shell through the cooperation of the draught fan, an air suction
pipe and the dust suction head.
