PROBLEM TO BE SOLVED : To provide an agricultural product sorting device, which gives a high sorting precision and excellent working efficiency, by eliminating water from a sorting belt to prevent disturbance in detection or detection error of agricultural products caused by adherence of a conveyor belt to a weight detector. SOLUTION : The agricultural product sorting device includes : an endless conveyor belt 68 for conveying agricultural products; a grade detector 75 for grading farm products on the endless conveyor belt 68; a delivery device 84 for delivering, by the endless conveyor belt 68, the farm products which have been detected to be suitable for the set grade; and a collection part 93 for collecting the farm products delivered from the delivery device 84. In the apparatus, a discharging path 110 for discharging water entered in between the endless conveyor belt 68 and the grade detector 75 is formed on a grade determination plate 78. Also, the discharging path 110 is formed in the direction along with or the perpendicular direction to the conveying direction of the endless conveyor belt 68, while the width of the discharging path 110 is formed to be widening from the front end and the rare end of the flow down direction and the depth is formed deeper from the front end and the rare end of the flow down direction.
