Abstract

The invention provides a grain combine harvester with a drying function, and belongs to agricultural machinery. A hot smoke acquiring and distributing device is fitted on a grain harvester combine body and is communicated with a hot smoke exhausting pipe of engine. Hot gas delivering pipes communicate the hot smoke acquiring and distributing device to a threshing device, a separating device, a selecting device, a grain delivering device, a grain bin and a grain discharging device. The heat of hot waste gas exhausted by the engine of the grain harvester combine is utilized, heat is added in each mechanical device for the grains in the grain combine harvester to pass by, accordingly the grains can be dried, parts of free water and combined water in the grains are allowed to evaporate, beneficial conditions are created for post-operation of a drier, and the grain combine harvester has the advantages that novel and reasonable design, fine operating effect, reliability of usage, efficient drying energy and low drying cost.

Description

technical field

[0001] The invention belongs to agricultural machinery, and mainly relates to a combined grain harvesting machine equipped with a grain drying device. Background technique

[0002] At present, the existing self-propelled grain combine harvesters with self-equipped power machines generally only have the functions of threshing, separation, cleaning, storage and grain unloading after harvesting. Due to structural design defects, existing self-propelled grain combine harvesters of various structures All grain combine harvesters do not have a drying function, that is, they are not equipped with a grain drying device. In the actual grain harvesting production operation, the relatively high value of free moisture and combined moisture carried by the grain itself has not been evaporated, and the moisture content of the harvested grain is large, which brings difficulties to the drying operation of the grain dryer after the harvesting operation , and cause an increase...
