Background

The grain as a commodity with special importance in use value has the following two distinct characteristics in the reproduction process: the seasonal production of the grains corresponds to the annual consumption which cannot be consumed by one day or in short; second, natural reproduction and economic reproduction are interwoven together. The seasonality and instability of grain production and the perennial and continuous nature of grain consumption determine that certain grain storage must be carried out to solve the contradiction between supply and demand and ensure perennial consumption. Otherwise, the surplus is difficult to adjust, and the supply and demand are unbalanced.

Small grain storage bins are arranged in various places, and for small storage bins which are relatively large, the proportion of the total cost of automatic warehouse entry and automatic warehouse exit equipment is higher than that of large storage bins, so that how to design automatic warehouse exit and warehouse entry equipment at low cost for the small storage bins is necessary.
