Abstract
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.
