Rotatable sun-drying device

Abstract

The invention relates to the technical field of sun-drying devices, in particular to a rotatable sun-drying device. A barrel cavity is arranged in a transparent barrel and provided with a barrel cover, a ring is arranged at the right end of the transparent barrel, part of the ring is rotatably positioned in a containing cavity positioned in a supporting seat, a first driving rod is arranged at theleft end of the transparent barrel and rotatably connected on a first vertical rod which is rotatably connected with a cross rod, and the cross rod is positioned above the first driving rod and is higher than the transparent barrel; transmission between the first driving rod and the cross rod is realized through a toothed belt, blades are detachably arranged at one end of the cross rod, a clamping block is arranged at the bottom end of the first vertical rod, a clamping groove is formed in the clamping block, a chuck is positioned in the clamping groove, an adjusting rod is arranged below thechuck, the bottom end of the adjusting rod is positioned in a mounting cavity which is positioned in the supporting block, and a worm gear is arranged in the mounting cavity, socketed at the bottom end of the adjusting rod in a threaded manner and matched with a worm which rotatably penetrates the supporting block to be connected with a roller. The rotatable sun-drying device can realize seed sun-drying effectively.

Description

Technical field [0001] The invention relates to the technical field of drying devices, in particular, to a rotary drying device. Background technique [0002] For the crop seeds used to retain seeds, especially rice seeds, large farmers in rural areas generally adopt single-seed harvesting, and they are dried separately after harvesting, cleaned and classified, sterilized, and soaked in warm soup before sowing. Crop seed drying is the first process after harvesting. It can promote seed maturity, increase seed enzyme activity, reduce seed moisture content, increase seed germination rate, insecticide and sterilization, and reduce the occurrence of pests. [0003] At present, in rural areas, the sun is usually chosen for planting, that is, the newly harvested rice seeds with extremely high water content are spread on the cement floor or asphalt pavement. After 2-3 days of sun exposure, the seeds are dried. [0004] However, the harvest time of rice seeds is still in the high temperatur...

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.
