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.

The invention disclosed is a plant maintenance apparatus to move along a plant or line of plants. The apparatus has a support frame to connect to a prime mover to move the apparatus. A sensing member is mounted from the frame, to contact and be deflected by the plant as the apparatus is moved. A sensor to senses the deflection and if the deflection is above a threshold it issues a signal to an actuator. There is a near ground member, mounted from and moving with the frame. The near ground member acted on by the actuator, so that when the threshold is met the near ground member moves to a first position away from the plant when immediately adjacent thereto, and then moves to a second position once past said plant. The result is the near ground member can treat a ground or soil or otherwise at or near a plant at least when in the second position, including disturbing any non-desired plants on the ground, while moving away from and not disturbing the plant which is sensed and above the threshold when in the first position.
