Seed drying device

Abstract

The invention belongs to the technical field of seed processing equipment and particularly discloses a seed drying device. The seed drying device comprises a box body and a material plate slidably arranged in the box body. A material sweeping rod is arranged on the material plate, and the end of the material sweeping rod is connected with a rotary rod rotationally arranged on the material plate. An air cavity is formed between the rotary rod and the material plate, and blades are arranged on the rotary rod. Cavities mutually communicating are formed in the rotary rod and the material sweepingrod, and an air outlet is formed in the side wall of the material sweeping rod. A gap is formed between the material sweeping rod and the material plate. A nozzle slides on the bottom wall of the boxbody, and a cylinder is arranged at the bottom of the box body. A piston is arranged in the cylinder, and a push rod connected with the material plate is arranged on the piston. A corrugated cover isconnected between the cylinder and the material plate in a sealed mode, and a pneumatic telescopic rod is arranged on the bottom wall of the box body. The interior of the corrugated cover communicateswith the interior of the pneumatic telescopic rod, and the pneumatic telescopic rod is connected with the nozzle. A heater is arranged on the lower portion of the cylinder, and the lower portion of the cylinder communicates with the nozzle. An elastic piece is arranged between the nozzle and the box body, and the upper portion of the cylinder and the air cavity communicate in a unidirectional mode. According to the seed drying device, mechanical drying of seeds is achieved, the drying efficiency is high, and the drying effect is good.

Description

technical field [0001] The invention belongs to the technical field of seed processing equipment, in particular to a seed drying device. Background technique [0002] Generally, the moisture of newly harvested seeds is as high as 25%-45%. The seeds at this time are not suitable for storage, and the following hazards are likely to occur during storage: First, the respiration of high-moisture seeds is relatively strong, which will release a lot of heat, which is easy to cause the seeds to rot. Mildew; second, some seeds will produce alcohol due to hypoxic respiration, which will poison the seeds and reduce seed activity; third, when high-moisture seeds encounter low temperatures, they are prone to freezing, reducing seed activity, and even causing seed death; Fourth, high-moisture seeds tend to germinate when the temperature reaches a certain level, making the seeds unusable; fifth, high-moisture seeds are also prone to breeding insects and endangering seed safety. Therefore,...
