An on-line drying device and harvester for grain transportation in harvesting state in the field

Abstract

The invention provides an on-line drying device and a harvester for grain transportation in the field harvesting state, comprising a screw conveying device, a microwave emitting device, an exhaust fan, a temperature sensor, a humidity sensor and a control unit; the screw conveying device includes a main shaft, a spiral blade, a pipeline wall, driving device and air hole; the driving device is installed at one end of the main shaft, and the exhaust fan is also installed at this end and outside the driving device; the spiral blade is arranged on the main shaft, and there is a gap between the outer edge of the spiral blade and the pipe wall; There are several circles of air holes near the edge; the microwave emitting device is arranged around the periphery of the screw conveying device; the microwave emitting device includes a hollow cavity and multiple microwave emitting elements; the hollow cavity is a ring structure with a cavity inside, and the inner cavity of the hollow cavity The circle is provided with several round holes; the microwave emitting element is arranged in the hollow cavity, and the control unit is respectively connected with the driving device, the microwave emitting device, the exhaust fan, the temperature sensor and the humidity sensor.

Description

technical field [0001] The invention belongs to the technical field of combine harvesters, and in particular relates to an on-line drying device for grain transportation and a harvester in a field harvest state. Background technique [0002] The combine harvester is an important tool for grain harvesting, but because the newly harvested grains of the combine harvester have high moisture content and are prone to heat, it is difficult to send the harvested grain directly to the grain depot or storage, and it needs to be dried naturally outside the field or using a special The device is dried. If the grain harvested by the combine harvester is directly stored in the grain depot, it will easily cause the accumulation of humidity and heat, resulting in mildew of the rice. It is often necessary to concentrate the work of drying the grain, which will consume considerable manpower and material resources. If the grain is quickly dried during the harvesting process in the field, the ...

Problems solved by technology

However, in the prior art, when the grain is transported to the grain tank and then dried, there is uneven heating, the drying efficiency is low, and the space of the working parts of the harvester is occupied.
