Dry and wet conversion device of dry and wet dual-purpose sweeper truck and dry and wet dual-purpose sweeper truck

The invention discloses a dry and wet conversion device of a dry and wet dual-purpose sweeper truck. A dustbin (1) is divided into an upper layer and a lower layer by a dustbin partition plate (4). A first outlet is formed in the tube wall of a dust suction tube (8). The dry bin is communicated with an air inlet of a centrifugal dust remover (9) and an outlet in the top end of the dust suction tube (8), and the wet bin is communicated with a dust exhaust port of the centrifugal dust remover (9) and the first outlet of the dust suction tube (8). A ventilation door rotating shaft (14) is arranged inside the dust suction tube (8), one end of a ventilation door (13) is fixedly connected with the ventilation door rotating shaft (14), a ventilation door rotating shaft driving device drives the ventilation door rotating shaft (14) to rotate, and accordingly the ventilation door (13) is driven to rotate. According to the dry and wet conversion device and the dry and wet dual-purpose sweeper truck, the structure is simple, operation is convenient, the bag pasting phenomenon due to the existence of a large amount of moisture in the dustbin is avoided after the dry and wet dual-purpose sweeper truck is converted to be in a dry working mode from a wet working mode, so that the working performance of the dry and wet dual-purpose sweeper truck is greatly improved, and wide practical value is achieved.
