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. An auxiliary air pipe is provided below a main air pipe to assist soil-cleaning operations and avoid generating pits on a ridge due to concentrated wind power of the main air pipe. The air vent direction reversal, adjustment of the air power of the air blower and automated direction reversal of the soil-retaining device when moving among ridges are achieved by using the angular sensor (7) and the controller (19), thus achieving a high level of technological intelligence.
