Abstract: A grapevine soil-cleaning device and engineering machinery installed with the soil-cleaning device, comprising an air blower (4), an air vent direction reversal device, a soil-retaining device, an angular sensor (7) and a controller (19). The controller (19) is connected to the air blower (4), the angular sensor (7), the air vent direction reversal device and the soil-retaining device respectively. The present device achieves non-contact soil cleaning by blowing air, and has the advantages of no harmful impact on buds and branches, one-time cleaning, and highly efficient soil cleaning. The air vent direction reversal device may achieve a consistent air-blowing direction when the grapevine soil-cleaning device moves among rows of the grapevine. The soil-retaining device may hold back the blown soil and reduce the displacement distance of the blown soil.
