Drying device capable of being screened

Abstract

The invention relates to the technical field of drying devices, and relates to a drying device capable of being screened. The device comprises a horizontally-arranged transparent cylinder, wherein a cylinder cavity is formed in the transparent cylinder, and a cylinder cover is arranged in the cylinder cavity; filter holes are formed in the side wall of the transparent cylinder; a transparent blocking cover is arranged in the circumferential direction of the transparent cylinder, a blocking cavity is formed in the transparent blocking cover, and the blocking cavity is in communication with thefilter holes and the maximum diameter of a cross section of the blocking cavity is gradually increased from right to left; a first sleeve connection bearing and a second sleeve connection bearing aresymmetrically connected to the periphery of the transparent blocking cover in a sleeve mode, and the lower portion of the outer ring of the first sleeve connection bearing and the lower portion of theouter ring of the second sleeve connection bearing are connected to corresponding support bases respectively; the left end of the transparent blocking cover is connected to a third sleeve connectionbearing in a sleeve mode, the third sleeve connection bearing is located on the left side of the first sleeve connection bearing, a transparent round plate is connected to the third sleeve connectionbearing, and a round cavity is formed in the transparent round plate; a plurality of first discharge holes are formed in the left side of the blocking cavity, and the first discharge holes are in communication with the round cavity; and a supporting plate is arranged below the transparent round plate. According to the device, seeds can be effectively dried, and powder can also be screened out forcentralized treatment.

Description

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