A tractor suspension type automatic transplanting machine for plug tray seedlings includes land wheels, a machine frame, a three-point linkage, a seedling pickup mechanism, a plug tray conveying device, a plug tray recovery device, seedling separating and planting devices driven by land wheels, and a watering device. Through front and rear drive cylinders, the seedling pickup mechanism is driven to move front and back to pick up seedlings above plug trays and release seedlings above a seedling guide device. Juxtaposed left and right seedling pickup modules in the seedling pickup mechanism are driven by left and right drive cylinders, to move left and right and pick up seedlings after combing, and to release seedlings after separating towards left and right. Plug trays fall onto a plug tray conveyor belt of the plug tray recovery device and slides into a plug-tray-recovery stacking box.

A grapevine soil-cleaning device and engineering machinery installed with the soil-cleaning device, comprising an air blower (), an air vent direction reversal device, a soil-retaining device, an angular sensor () and a controller (). The controller () is connected to the air blower (), the angular sensor (), 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 () and the controller (), thus achieving a high level of technological intelligence.
