Background

Cereals including rice, wheat, millet, soybean, etc., are mainly plant seeds and fruits, and are traditional staple food for many asian people. Cereals, not only refer to seeds of gramineous plants, but also can be roughly divided into three types in China, wherein the first type is cereals, including rice (indica rice, japonica rice and rice), wheat (wheat, barley, oat and rye), corn, sorghum, millet, yellow rice, buckwheat and the like; the second kind is bean product, including soybean, broad bean, pea, mung bean, small red bean, kidney bean, etc.; the third category includes potatoes, including sweet potatoes also known as sweet potatoes or sweet potatoes, yams, taros, cassava, and the like.

The airing treatment is needed before the storage of rice, wheat, corn and some bean grains, the airing treatment is carried out on the grains for reducing free water in seed cells so as to reduce respiration, meanwhile, the seeds are spread during airing so that the airing is more sufficient, and meanwhile, heat generated by respiration can be released, so that the activity of enzymes related to the respiration is properly reduced; the respiration is reduced, the organic matter in the seeds can not be rapidly decomposed, and the economic loss is reduced.

During airing, large places such as an airing field and an playground of a warehouse in a large area are needed, then grains are carried to airing places, and airing is carried out in a mode of overturning the grains on a stall, so that airing personnel are needed to uniformly spread grains on the ground by means of tools, and the grains are manually turned over after being aired for a period of time, so that the grains are aired more uniformly and fully.

However, the airing mode is easily limited by places, and farmers who do not have large-area airing places nearby some houses can usually only air on roads, occupy road areas, cause adverse effects on traffic, or transport to places far away for airing, so that the grains are not turned over conveniently at regular time, and the grains cannot be timely folded when meeting weather problems such as rain.

The agricultural airing device with the patent application number of CN201810106709.8 structurally comprises a storage box and a base, wherein a first lead screw, a first lead screw nut, a second lead screw nut, a third lead screw and a third lead screw nut are arranged on the base, and three platforms are connected through the first lead screw nut, the second lead screw nut and the third lead screw nut; above-mentioned patent is spreading the platform lifting of spilling cereal three through three lead screw and screw-nut and is going on the sunning to different height, has realized three-dimensional sunning though to practiced thrift the space, but cereal tiling can't turn after to the platform, it is inhomogeneous to lead to the sunning between upper cereal and the lower floor's cereal, can only artifically turn, perhaps reduce the sunning layer thickness, reduce cereal sunning volume, consequently, the structure that turns is lacked in above-mentioned patent, it is inconvenient to use.

Based on the above, the invention designs a three-dimensional agricultural grain airing device and a using method thereof, so as to solve the problems.
