a drying device

Abstract

The invention relates to the technical field of seed sun-drying devices, in particular to a seed sun-drying device. The seed sun-drying device comprises a transparent drum which is horizontally arranged. The transparent drum is internally provided with a drum cavity. One side of the drum cavity is open, and the drum cavity is provided with a drum cover. A circular ring is arranged at the right endof the transparent drum in the circumferential direction. The circular ring is partly rotatably located in a containing cavity. The containing cavity is formed in a support seat. The support seat islocated below the transparent drum. A first driving rod is arranged at the left end of the transparent drum in the axial direction and rotatably connected to a first vertical rod. The bottom end of the first vertical rod is located in a mounting cavity. The mounting cavity is formed in a support block and internally provided with a worm wheel. An external thread is arranged at the bottom end of the first vertical rod. The worm wheel is connected to the bottom end of the first vertical rod in a threaded and sleeving manner and matched with a worm. After rotatably penetrating the support block,the worm is connected with a rotating wheel. By means of the seed sun-drying device, seeds can be sun-dried effectively.

Description

technical field [0001] The invention relates to the technical field of seed drying devices, in particular to a seed drying device. Background technique [0002] The crop seeds used for saving seeds, especially rice seeds, are generally collected by large grain farmers in rural areas. After harvesting, they are dried separately, cleaned and graded, sterilized, soaked in warm water before sowing, etc. Drying crop seeds is the first process after harvesting. It can promote the post-ripening of seeds, increase the activity of seed enzymes, reduce the water content of seeds, increase the germination rate of seeds, and can also kill insects and bacteria, and reduce the occurrence of diseases and insect pests. [0003] At present, in rural areas, sun-dried seeds are usually selected, that is, the freshly harvested rice seeds with extremely high water content are spread on the cement field or asphalt road, and after 2-3 days of sun exposure, the seeds reach a dry degree.

Problems solved by technology

[0004] However, the harvesting time of rice seeds is still in the high temperature period in autumn. Sometimes the weather temperature is above 35°C. In the afternoon, the temperature accumulated on the cement field or asphalt road will be very high, which is easy to burn the seeds and reduce the germination rate.

Therefore, it is very unfavorable to maintain the quality of the seeds to expose the rice seeds on the open-air cement field or asphalt road, especially in continuous high temperature weather; in addition, after the rice seeds are piled up to a certain height, the rice in the lower layer is often unable to be exposed to the sun. However, this will result in uneven drying of seeds and poor results, which will affect the yield in the later period.
