A system for de-plugging ground engaging tools of an agricultural implement includes a ground engaging tool. A fluid nozzle is in fluid communication with a pressurized fluid source such that pressurized fluid from the pressurized fluid source is flowable to the fluid nozzle. The fluid nozzle is oriented towards the ground engaging tool. Thus, pressurized fluid from the fluid nozzle is flowable towards, next to and/or against the ground engaging tool.

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.

A self-moving device and a control method for a self-moving device are disclosed. The self-moving device includes a moving module, a control module and an adjusting device. The moving module includes a track, driven by a drive motor to drive the self-moving device to move. The control module controls the adjusting device to adjust a grounding length of the track, such that the grounding length of the track when the self-moving device turns is smaller than that of the track when the self-moving device moves straightly. The control method for a self-moving device includes the steps: controlling to reduce the grounding length of the track before the self-moving device is controlled to turn; and controlling to increase the grounding length of the track after the self-moving device is controlled to finish the turning.
