Seed screening and drying device

Abstract

The invention discloses a seed screening and drying device. The top of a box body is provided with a feed port. A vibrating screen is arranged under the feed port and is of an inclined structure in the box body, and one side of the part between the feed port and the vibrating screen is provided with a first air blower. A waste outlet is formed opposite to an air outlet of the first air blower, aninclined plate is arranged on the waste outlet, and the inclined plate is arranged in the box body and connected to the inner wall of the box body through welding. The drying cavity is internally provided with a stirring shaft, the stirring shaft is fixedly provided with a plurality of stirring blades, the drying cavity is internally and fixedly provided with two drying pipes, and the two drying pipes are symmetrically arranged on the two sides of the stirring shaft. The side face of the drying cavity is provided with a discharge port, the discharge port is fixedly provided with a connection block, the two sides of the connection block are symmetrically provided with sliding grooves, a baffle is connected into the sliding grooves in the two sides of the connection block in a sliding manner, and the end face of the baffle is further provided with a handle.

Description

technical field [0001] The invention relates to the technical field of agricultural product equipment, in particular to a seed screening and drying device. Background technique [0002] Generally, newly harvested seeds have a water content of 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, part of the seeds will produce alcohol due to hypoxic respiration, alcohol will poison the seeds and reduce the activity of the seeds, third, when the seeds with high moisture are exposed to low temperature, they are easy to be frozen to reduce the activity of the seeds, and even cause the seeds to die. Fourth, when the temperature reaches a certain level, high-moisture seeds are easy to germinate, making the seeds unusable. Fifth, high-moisture seeds are als...

[0002] Generally, newly harvested seeds have a water content of 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, part of the seeds will produce alcohol due to hypoxic respiration, alcohol will poison the seeds and reduce the activity of the seeds, third, when the seeds with high moisture are exposed to low temperature, they are easy to be frozen to reduce the activity of the seeds, and even cause the seeds to die. Fourth, when the temperature reaches a certain level, high-moisture seeds are easy to germinate, making the seeds unusable. Fifth, high-moisture seeds are also prone to breeding insects, which endanger the safety of seeds. At the same time, there are more shriveled seeds in newly harvested seeds , and doped with dust and other particles in the seeds, the preservation of the seeds needs to be removed and then stored. However, the traditional method is to first dry the seeds in the sun or in the sun, and then put the seeds inside This method is not only labor-intensive, but also needs to occupy space, and it is time-consuming and laborious, and the drying effect of the seeds is not good.
