technical field

The invention relates to the field of seed drying equipment, in particular to a seed drying machine.

Background technique

Seeds are the reproductive system of seed plants, which play an important role in the continuation of species, but seeds cannot be sown at any time. In order to ensure that the seeds can continue to sow, grow, and reproduce in the next spring or longer, they need to be dried Or refrigerate to keep the seeds alive. However, cold storage often destroys the growth of the seeds themselves, so the method of preserving seeds is usually to dry and store. Due to the huge number of seeds and high requirements for drying effect, seed drying equipment is generally used to completely dry the seeds. Most of the existing drying equipment is that the seeds to be dried are still, resulting in uneven drying and drying. The drying effect is poor. In view of this, the present invention proposes a seed dryer to solve the above problems.

detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Please refer to Figures 1-2, the present invention provides a technical solution: a seed dryer, including a cylinder 1, the upper and lower ends of the cylinder 1 are provided with ports, and the side of the cylinder 1 is fixedly connected with a motor 2, The output end of the motor 2 is fixedly connected with the first rotating shaft 3, the first rotating shaft 3 runs through the side wall of the cylinder body 1, and extends toward the inner cavity of the cylinder body 1, and the extended end of the first rotating shaft 3 is detachably connected with the first bottom plate 4 by screw threads. A bottom plate 4 is fixedly connected with an outer drying plate 5 and an inner drying plate 6 on a side away from the first rotating shaft 3, and the inner drying plate 6 is provided with a heating wire 7, and the outer drying plate 5 and the inner drying plate 6 are both It is a ring-shaped plate, and the centers of the two drying plates are located on the same central axis, the heating wire 7 is located in the inner cavity of the inner drying plate 6, the outer drying plate 5 is provided with ventilation holes 14, and the inner drying plate 6 is provided with There are heat dissipation holes 15, and the seeds to be dried are placed in the cavity between the two drying plates, and they are heated and blown at the same time, and the seeds to be dried are constantly moving under the action of the motor 2 to accelerate the drying speed of the seeds , the two openings facing the cylinder 1 on the outer drying plate 5 are respectively provided with flip doors 8, and the two flip doors 8 are rotatably connected with the side walls of the outer drying plate 5 through hinges, and the two flip doors 8 are far away from the One end of the adjacent hinges is movably clamped to the side wall of the outer drying plate 5 through buckles, and two flip doors 8 are used for the input and output of seeds.
