Device for conveying and feeding wet material for cross-flow hot air combine harvester

A device for conveying and feeding wet material for cross-flow hot air combine harvester, comprising two parts:

• a hot air pumping part and a material conveying part;
• the hot air pumping part consists of an engine radiator, an exhaust guide hood, an exhaust pipe, an exhaust pump, an air supply pipe and a supply guide hood;
• one end of the exhaust pipe is connected with the engine radiator through the exhaust guide hood, and the other end of the exhaust pipe is connected with an air inlet of the exhaust pump;
• one end of the air supply pipe is connected with an air outlet of the exhaust pump, and the other end of the air supply pipe is connected with the air supply guide hood;
• the material conveying part consists of a chain rake conveying groove structure (A) and a cross-flow wind chamber structure (B) which are arranged over and under;
• the chain rake conveying groove structure LAS consists of a conveying groove housing, and a driving sprocket wheel, a driven sprocket wheel, a conveying chain and a chain rake which are located in the conveying groove housing;
• the conveying groove housing is the space for conveying material, the driving sprocket wheel is connected with the driven sprocket wheel through the conveying chain, and the chain rake is an L-shaped structure, which is connected with the conveying chain by riveting, and is equally distributed in the circumference direction of the conveying chain;
• the cross-flow wind chamber structure (B) is located at the lower part of the chain rake conveying groove structure (A), and includes a bottom plate of the conveying groove installed under a lower cover plate of the conveying groove, and the bottom plate of the conveying groove and the bottom surface of the conveying groove housing constitute the cross-flow wind chamber;
• the lower end of the cross-flow wind chamber structure (B) is an air inlet and connected with the air supply guide hood;
• the bottom surface of the conveying groove housing is machined with a series of air outlets and wind guide micro-structures, the wind guide micro-structures are located at the air outlets to guide the air flow towards the direction of a material feeding inlet.
