Harvester Waste Heat Drying System

Abstract

The invention discloses a waste heat drying system for a harvester, which comprises a heat collection device installed at the tail gas discharge device and a drying device installed on the top of the granary entrance, and the granary is equipped with a device for communicating with the drying device and providing hot air. There is an air distribution device connected between the heat collection device and the fan device; the air distribution device is used to ensure the consistency of the drying temperature and prevent excessive drying caused by excessive drying temperature; the heat collection device is used to Collect the waste heat of the exhaust gas discharge device, and the fan device is used to transfer the waste heat collected by the heat collection device to the air distribution device to the drying device to dry the grain in the granary. This embodiment is simple in structure, reasonable in design and recyclable The waste heat of the tail gas of the harvester dries the grain, which greatly reduces the humidity of the grain, thereby reducing the probability of mildew, thereby prolonging the storage time of the grain, reducing the cost of drying the grain in the later stage, and improving the energy utilization rate.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester drying system. Background technique [0002] At present, the harvester has become a commonly used agricultural machine when harvesting crops such as rice, wheat, corn, and soybeans, and is used for harvesting, threshing, separating and cleaning, storing and unloading grain. However, after the traditional harvester harvests and collects, because there is no drying device, the relatively high value of free moisture and combined moisture carried by the grain itself has not been evaporated and lost. The time is short, so it is necessary to use special grain drying equipment to dry the grain or complete the drying of the grain by artificial exposure. Although the above methods can achieve the drying of the grain, an additional grain dryer is used. The drying operation not only increases the energy consumption of the dryer, but also requires a lot of manpowe...

However, after the traditional harvester harvests and collects, because there is no drying device, the relatively high value of free moisture and combined moisture carried by the grain itself has not been evaporated and lost. The time is short, so it is necessary to use special grain drying equipment to dry the grain or complete the drying of the grain by artificial exposure. Although the above methods can achieve the drying and drying of the grain, an additional grain dryer is used to dry the grain. The drying operation not only increases the energy consumption of the dryer, but also requires a lot of manpower and material resources for auxiliary operations, which increases the cost of grain production and reduces the production efficiency of grain; while for the drying method of artificial exposure, it is only applicable It is suitable for dry treatment of small-yield grains, and is also limited by the influence of the weather and the occupation of the exposed ground, which makes the artificial exposure operation very inconvenient
