Cylinder push arm type transfer trolley

The invention discloses an air cylinder push arm type transfer trolley which comprises a transfer trolley body, a pneumatic push arm mechanism, a stacked tray one-by-one conveying mechanism and a chassis jacking device. The stacked tray one-by-oneconveying mechanism is vertically arranged on the transfer trolley body, and the pneumatic push arm mechanism is arranged on the transfer trolley body bycorresponding to the discharging position of the stacked tray one-by-oneconveying mechanism. When the trolley is in use, trays are stacked on the stacked tray one-by-oneconveying mechanism; then thetrays are transferred to a preset position through the transfertrolley body; at the moment, the trays are pushed to one side of the pneumatic pushing arm mechanism one by one through the stacked trayone-by-oneconveying mechanism and then the trays are pushed out to a preset position through the pneumatic pushing arm mechanism, so that the purpose of automatic tray feeding is achieved and intelligent automatic tray feeding
