Description

Technical Field

[0001] The utility model relates to the technical field of article conveyors, in particular to an internal conveyor of a gas-controlled warehouse. Background Art

[0002] A controlled atmosphere warehouse is a warehouse that prolongs the storage period of food and other items by adjusting the gas composition inside the warehouse. Due to the special environment inside the controlled atmosphere warehouse, it will take a lot of time to store and take out fruits and vegetables manually using conventional transportation methods. If humans stay in this environment for too long, it will cause harm to the human body. In order to save time, internal conveyors are usually used to transport fruits and vegetables to achieve the effect of convenient and fast transportation. There are many types of internal conveyors on the market, and most of them use motors to drive the conveyor belt to rotate to complete the transportation operation.

[0003] The two ends of this type of internal conveyor are generally set at the feed port and the discharge port, and the feed port is generally sealed with a sealed door. When loading and unloading, the sealed door needs to be opened for a long time, which further causes the air inside the controlled atmosphere storage to flow outward, which is not conducive to reducing the loss of internal air. Once the air loss of various components is large, the interior of the controlled atmosphere storage needs to be re-operated and the internal air components adjusted, resulting in more resources being consumed and inconvenience to users. In view of this, we proposed an internal conveyor for the controlled atmosphere storage. Utility Model Content
