The utility model relates to a seeder, which comprises a frame, a screening device and a conveying mechanism.The screening device includes a cage, which is arranged on the frame body, and a plurality of gaps around the cage which are not allowed to pass through the fruit core are arranged.The conveying mechanism includes a shaft and a plurality of rows of rods, which limit the rotation of the shaft in the cage, and two rows of adjacent rods are staggered with each other, and each rod is fixed at the position where the shaft is surrounded by the cage.When the shaft rotates relative to the cage, the shaft drives the rod body to move in a circle, and the rod body has a stirring effect on some fruits entering the cage. The pulp of these fruits is peeled off the core by the rod body, so as to achieve the effect that the core remains in the cage and the pulp leaves the cage from the gap.一種脫籽機，包括一架體、一篩選裝置與一輸送機構。該篩選裝置包括一籠子，其設在架體上，在籠子的周圍佈置若干不允許果核通過的間隙。該輸送機構包括一軸與多排棒體，限制該軸在籠子裡面轉動，而且二排相鄰的棒體彼此錯開，每根棒體固定在軸被籠子環繞的部位。當軸相對籠子轉動，該軸帶動棒體進行圓周運動，該棒體對一些進入籠子的水果產生攪拌作用，這些水果的果肉被棒體剝離果核，達到果核留在籠內、果肉從間隙離開籠子的去籽效果。
