A rotary drying device

Abstract

The invention relates to the technical field of drying devices, and relates to a rotary drying device. A cylinder chamber is provided in a transparent cylinder, and a cylinder cover is provided in the cylinder chamber; a ring is provided at the right end of the transparent cylinder, and part of the ring is rotatable. It is located in a receiving cavity, and the receiving cavity is located in the supporting seat; the left end of the transparent cylinder is provided with a first driving rod, which is rotatably connected to the first vertical rod; the first vertical rod is also rotatably connected to the horizontal rod, and the horizontal rod Located above the first drive rod and higher than the transparent cylinder; the first drive rod and the cross bar are driven by a toothed belt, and one end of the cross bar is detachably provided with a blade; the bottom end of the first vertical rod is provided with a block, and the block There is a card slot inside, the card head is located in the card slot, and an adjustment rod is provided under the card head. The bottom end of the adjustment rod is located in the installation cavity, and the installation cavity is located in the support block; there is a worm wheel in the installation cavity, and the worm wheel is threaded. At the bottom end of the adjusting rod, the worm wheel cooperates with the worm, and the worm rotatably passes through the support block and is connected with the running wheel. The invention can effectively dry seeds.

Description

technical field [0001] The invention relates to the technical field of drying devices, in particular to a rotary 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.
