This utility model discloses a tray-loading system detection device and a tray-loading machine. The tray-loading system detection device includes a circuit switch, a blocking magnet, an inspection unit, a bracket, and a controller. The blocking magnet includes a housing and a piston. The housing includes a first bottom surface, a second bottom surface, and a side surface. The first bottom surface includes a first hollowed-out unit, and the second bottom surface includes a second hollowed-out unit. The piston moves to either the first hollowed-out unit or the second hollowed-out unit. The two ends of the bracket are respectively connected to the side surface of the housing and the inspection unit. The inspection unit can detect whether the piston has moved to the second hollowed-out unit. The circuit switch includes an energizing relay and a delay relay. The energizing relay is connected to the blocking magnet and the controller, and the delay relay is connected to the inspection unit and the controller. The inspection unit is also connected to the controller. By adding an inspection unit to the tray-loading system detection device to detect the movement position of the piston, the detection of cigarette obstruction is achieved, improving the accuracy of the detection.

The present application relates to geotechnical engineering freezing technical field, disclose a kind of frozen soil-structure surface place frozen soil erosion indoor test simulation device, including installation unit, transmission unit and cleaning unit: installation unit includes experiment table, cavity is opened in experiment table, support leg is fixedly installed around the bottom of experiment table.This application, when the driving assembly is operated, can also control the circular mounting plate to move, let it leave the middle of experiment table, ensure that frozen soil falls, when frozen soil falls, the driving assembly resets at this time, so that the first inner guard plate and the second inner guard plate close, can be watered inwards, at this time, the driving assembly is started again, so that the first inner guard plate and the second inner guard plate can reciprocating rotation slightly, so as to make the water to the first inner guard plate and the second inner guard plate inner wall shake cleaning, repeat several times in this way, ensure that the frozen soil residue impurities on the first inner guard plate and the second inner guard plate inner wall can be cleaned thoroughly.
