This application provides a seed cutting device, comprising: a seed cavity for accommodating a single seed and fixing its orientation; a first limiting member, movable within the seed cavity along a first direction to limit the seed in the first direction; a second limiting member, movable within the seed cavity along a second direction to limit the seed in the second direction; the first direction and the second direction are not parallel to each other, and the first limiting member and the second limiting member limit the seed within the seed cavity; and a cutter capable of penetrating the second limiting member and movable to cut the seed after it has been limited. The seed cutting device, through the seed cavity and the corresponding movable limiting members, effectively limits the seed within the seed cavity, ensuring that the seed does not move during the cutting process and that the seed maintains a relatively stable position during batch cutting, thereby achieving a stable size of the embryo head and embryo tail.

According to the technical scheme, the seed cutting equipment comprises a seed containing cavity used for containing a single seed and fixing the orientation of the seed; the first limiting piece is movably arranged in the seed containing cavity in the first direction so as to limit the seeds in the first direction; the second limiting piece is movably arranged in the seed containing cavity in the second direction so as to limit the seeds in the second direction; the first direction is not parallel to the second direction, and the first limiting piece and the second limiting piece limit seeds in the seed containing cavity; and the cutter can intrude into the second limiting piece and is movably arranged to cut the limited seeds. According to the seed cutting equipment, the seeds are limited in the seed containing cavity through the seed containing cavity and the multiple corresponding movably-arranged limiting pieces, it is guaranteed that the seeds do not move in the cutting process, it is guaranteed that the seeds have the relatively stable position in the batch cutting process, and therefore embryo heads and embryo tails with the stable sizes are stably obtained.
