Aerodynamic aquatic weed removal and decontamination devices and decontamination methods are disclosed. In an embodiment, the aerodynamic aquatic weed removal and decontamination device includes a boat body and a shore-based device for remotely controlling the boat body. The boat body includes a power unit, a weed removal and decontamination unit, a positioning system, an environment perception system, and a shipborne controller. The power unit includes an engine, a propeller connected to the engine, and a rudder servo motor configured to control a heading of the boat body. The weed removal and decontamination unit includes a mesh conveyor. The positioning system includes a positioner configured to obtain real-time location information and heading information of the boat body. The environment perception system includes a wind sensor and a visual sensor. The shipborne controller is configured to control a navigation state of the boat body.

An automatic feeding device and method for a seedling bed of a transplanter, comprising: a bracket installed on the transplanter; several trays, obliquely arranged on the bracket downwards, and the bottom of the trays being provided with release mechanisms for releasing the rice seedling bed; a conveyor belt, arranged on the bracket; a photoelectric sensor, arranged on the transplanting platform; and a controller, in communication connection with the photoelectric sensor, when the photoelectric sensor detects that the height of the remaining rice seedling bed on the transplanting platform is lower than the height of the photoelectric sensor. Only one driver is needed to operate, so that the labor input is greatly reduced, and the labor intensity is reduced; meanwhile, the space is saved by the reduction of the number of workers, enabling more seedling raw materials to be stored.
