Abstract: A device for conveying and feeding wet material for a cross-flow hot air combine harvester, the device consisting of a hot air pumping part and a material conveying part. The hot air pumping part uses an air suction pump (4) to pump a flow of hot waste air from an engine radiator (1) of the combine harvester by means of an air suction pipeline (3) so as to provide hot air flow for the material conveying and feeding device. The material conveying part consists of a chain harrow-type conveying groove structure (A) and a cross-flow air chamber structure (B), wherein the chain harrow-type conveying groove structure (A) is located at an upper part of the cross-flow air chamber structure (B) and is used for forcibly conveying and feeding a material; and the cross-flow air chamber structure (B) uses hot air to dry the material, blows to assist in feeding the material, and uses a cross-flow air wheel (14) to forcibly feed the material. By using excess heat that is generated by the engine of the combine harvester to perform auxiliary blowing and drying during the process of conveying and feeding a wet material, the feeding device may lower the temperature of the engine and reduce the effects of heat radiation and ageing that high temperatures have on surrounding devices, and may lower the water content of a wet agricultural material, thus preventing blockages produced because of moisture.
