The invention relates to an internet-of-things-based intelligent security inspection
machine comprising a conveyor, a protective cover, a base, a cleaning mechanism, an elevating mechanism, a controlpanel and a display screen. The cleaning mechanism consists of a first drive
assembly, a first support frame, a first moving block, a first transmission rod, a spring, a second transmission rod, an opening slot, a third transmission rod, a first support rod and a fourth transmission rod. The elevating mechanism includes a second driving
assembly, a transmission
assembly, a lifting assembly, and asecond support frame and a second support bar. According to
the internet-of-things-based intelligent security inspection
machine, with the cleaning mechanism, when the security inspection
machine carries out security inspection on rainy days, the rainwater and mud on the conveying belt of the conveying machine can be cleaned well, so that the possibility of
wetting of other security inspection articles by the rainwater on the conveying belt is reduced and thus the practicality of the security inspection machine is improved; with the elevating mechanism, elevation of the protective cover is driven and thus articles with different dimensions can pass through the inlet and outlet of the security inspection machine successfully, so that the practicability of the security inspection machine isfurther improved.
