A silo bottom structure comprises a cylindrical wall portion (10), a circular beam (20), a support wall (40), a support post (50), and a discharge hopper (30) having an inlet and an outlet. The cylindrical wall portion (10) comprises a cylindrical wall (11) and wall posts (12) arranged at intervals in circumference along the inside of the cylindrical wall (11). The cylindrical wall (11), the wall post (12), the support wall (40) and the support post (50) are separately supported on a foundation. An outer edge of the discharge hopper (30) is supported on the wall post (12) through the circular beam (20). The discharge hopper (30) is further supported on the foundation through the support wall (40) and the support post (50). A silo has the above silo bottom structure. Through the above technical solution, the silo bottom structure can provide support of sufficient strength without using excessive stuffing, and can also reduce the dead weight of the silo, thereby reducing the manufacturing cost and the requirement for the foundation.

Abrégé

Disclosed is a silo, comprising a silo wall (1), a silo top (2) and a silo bottom structure, and also a central post (7) for supporting the silo top (2), the central post (7) being of a hollow tubular shape, a detection device being provided on the outside wall (8) of the central post (7), and a first opening (9) being provided at an upper end of the central post (7). The silo has a robust structure, good bearing capacity, and is favourable for disposing and arranging a detection device within the silo, such that the temperature, the humidity and other conditions within the silo can be detected conveniently, and in addition, the space inside the central post is accessible via the first opening at the top thereof for maintenance of the detection device and so on.
