Technical Field

[0001] The utility model belongs to the technical field of seed drying, and particularly relates to a crop seed dryer. Background Technique

[0002] Crop seeds are the structures formed after the ovules of seed plants are fertilized, generally composed of seed coats, embryos, endosperms, etc. The embryo is the most important part of the seed and grows into a new individual after germination. The endosperm contains nutrients. Seeds are the unique reproductive bodies of gymnosperms and angiosperms, formed by the pollination and fertilization of ovules; during the cultivation process of crop seeds, it is necessary to sterilize and dry the seeds to ensure that the seeds are not easily damaged and to improve the germination rate of the seeds.

[0003] Chinese Patent Publication No. CN216668161U discloses a crop seed drying device, which includes a placement plate, sliding columns, fixing plate A and fixing plate B. The left and right ends of the placement plate are fixedly connected to the sliding columns, and the sliding columns pass through and are slidably connected to fixing plate A and fixing plate B. The sliding columns are provided with handles connecting the cylinders at both ends of the sliding columns. The seeds are placed on the placement plate and dried in the sun, and the seeds on the placement plate are turned over by pushing the handle back and forth, which improves the drying efficiency.

[0004] In view of the above related technologies, the inventor found that at least the following problems exist in this technology: This drying device needs to manually push the handle to turn over, which increases the workload of personnel and is difficult to ensure uniform heating of the seeds, thereby affecting the drying quality of the seeds. At the same time, during the drying process of the seeds, some epidermis will fall off, and even there are some impurity residues, which affects the recovery after drying and the overall quality of the seeds. Therefore, we provide a crop seed dryer that can automatically turn over to ensure uniform heating of the seeds, and at the same time, can screen the epidermis and residues in the seeds.
