[0021] There are various installation methods for the bottom plates of the lower bin body 3 and the upper bin body 5, as well as the top plate of the lower bin body 3. For example: the bottom plates of the lower bin body 3 and the upper bin body 5 both adopt the cast-in-place reinforced concrete flat slab without beams system, the top plate of the lower bin body 3 adopts the cast-in-place reinforced concrete beam and slab system, and reinforced concrete ring beams are provided at the intersections of the bottom plates of the lower bin body 3 and the upper bin body 5 and the top plate of the lower bin body 3 with the corresponding bin walls; solar photovoltaic panels are laid on the bin top cover 6, grain inlet openings 11 are provided on the top plate of the lower bin body 3 and the bin top cover 6, ventilation channels 10 are provided on the bottom plates of the lower bin body 3 and the upper bin body 5, grain outlet openings 9 communicating with the corresponding overhead layers are provided, and cleaning doors 12 are provided on the bin walls. A grain retaining door 13 is provided inside the cleaning door 12, and a high-level grain discharging opening 16 is also provided on the bin wall of the lower bin body 3.
[0022] The grain inlet openings 11 on the lower bin body 3 and the bin top cover 6 are respectively connected to the corresponding grain inlet equipment for transporting grains into the lower bin body 3 and the upper bin body 5. The grain outlet openings 9 on the bottom plates of the lower bin body 3 and the upper bin body 5 are also respectively connected to the corresponding grain outlet equipment for transporting the grains in the lower bin body 3 and the upper bin body 5 out, so that the two bin chambers can independently complete the grain inlet and outlet operations; there are two high-level grain discharging openings 16 on the lower bin body 3, and a maintenance platform 17 and a ladder 18 are provided below each high-level grain discharging opening 16. The cleaning doors 12 on the lower bin body 3 and the upper bin body 5 are all located at the lower part of the bin body, and a rain shed 15 is provided above the cleaning door 12 and a cleaning platform 14 is provided below; the bin top cover 6 includes a conical roof 22, an upper ring beam 23, a lower ring beam 24 and a bin top platform 25. The conical roof 22 is fixedly installed on the top of the upper bin body 5 through the lower ring beam 24, the bin top platform 25 is fixedly installed on the top of the conical roof 22 through the upper ring beam 23.

This independence not only enhances the flexibility of the shallow silo during grain storage, enabling it to adapt to the grain storage requirements of multiple varieties and small batches, but also optimizes the grain handling process and improves the overall operation efficiency.
[0024] Furthermore, since the lower bin body 3 is elevated, a grain outlet 9 is provided on its bin bottom plate. This improvement greatly enhances the grain discharging efficiency and the degree of mechanized operation of the lower bin body 3. At the same time, the isolation design between the lower bin body 3 and the ground effectively enhances the moisture-proof ability of the bin body, providing a strong guarantee for the long-term storage of grains.

Moreover, the inner bin columns 20 are fixedly connected to the bottom plates of the lower bin body 3 and the upper bin body 5 respectively through column caps. By providing the buttress columns 19 and the inner bin columns 20, the bearing capacity of the shallow silo can be greatly improved.
