Claims

[Claims for Utility Model Registration] A hopper for supplying seeds; a seed carrier that moves while a surface provided with a number of suction holes for adsorbing seeds is in contact with a group of seeds accommodated in the hopper; and the seed carrier an exhaust mechanism that makes an inner space facing the outside that adsorbs the seeds with a negative pressure space; and a negative pressure cutoff mechanism that cuts off the negative pressure inside the seed carrier, and the seeds in the hopper are removed from the hopper. , When the suction hole that contacts the seeds is sucked by the negative pressure in the space, and the surface of the seed carrier moves to a predetermined position of the suction hole that suctions the seeds. , in a seed suction and discharge device configured such that the negative pressure cutoff mechanism shuts off the negative pressure in the space and the sucked seeds leave the seed carrier, in the vicinity of a position where the negative pressure is to be cut off. , a striking bar that can vibrate back and forth for applying vibration by striking from the outside of the seed carrier; a spring that biases the striking bar in the striking direction; and a spring that biases the striking bar in the striking direction; A cam mechanism for vibrating a striking bar; and a cam drive mechanism for driving the cam mechanism.
