Description

Technical Field

[0001] The utility model relates to the technical field of ventilation devices, in particular to a rice storage ventilation device. Background Art

[0002] Rice is typically stored in a warehouse. During storage, the moisture in the rice undergoes chemical reactions, generating a certain amount of heat. This accelerates the grain's spoilage and is detrimental to its storage. Therefore, the rice piles need to be ventilated. Ventilation ducts are typically placed on the ground, connected to fans, and equipped with ventilation holes to dissipate the accumulated heat.

[0003] However, existing ventilation ducts and fans are generally fixed. Forklifts are used when taking and transporting rice. The ventilation ducts set on the ground are not convenient for the movement of vehicles, which affects the transportation work. Moreover, the ventilation ducts and fans are fixed and not easy to disassemble, which limits the use of the warehouse. Utility Model Content
