Description

Technical Field

[0001] The invention relates to the field of warehousing, and in particular to a silo cleaning device and a silo cleaning method. Background Art

[0002] In agricultural product processing and various industrial fields, silos are usually used to store materials, such as grains to be processed. Generally, the discharge port of a flat-bottomed cylindrical storage silo is set at the bottom of the storage silo. When the discharge port is opened, the material above the discharge port of the storage silo will flow out along the discharge port under the action of gravity, and a large amount of material will remain in other parts of the bottom of the silo. For example, after a flat-bottomed silo storing 10,000 tons of corn is emptied, at least 2,000 tons of surplus grain will remain at the bottom of the silo. If this part of the surplus grain needs to be removed from the silo, it needs to be cleaned up manually or using a silo cleaning machine. During use, burial and stopping of the silo cleaning machine often occur, and manual labor is required to frequently enter the silo to clear the accumulated materials and restart the silo cleaning machine. Summary of the invention
