Grain throwing device and grain drying machine

Abstract

The invention provides a grain throwing device. The grain throwing device comprises a bottom plate and a guide component arranged on the bottom plate and used for guiding grains, wherein the guide component comprises a guide plate; the guide plate comprises an arc-shaped section and a straight section; an extension direction of the straight section is a tangential direction of the tail end of thearc-shaped section. The device is capable of uniformly throwing the grains and uniformly scattering the grains into a drying chamber, so that the problem that the grains are unevenly piled in the drying chamber can be effectively solved; the effective utilization rate of the space of the drying chamber and the grain drying efficiency are improved; the grains can be uniformly heated and are uniformin water content in the drying process; in addition, the invention also provides a grain drying machine comprising the grain throwing device; the grain drying machine is capable of uniformly drying the grains; the space utilization rate of the drying chamber is high; the drying quantity in unit time is high; the grains can be uniformly heated in the drying process; the water content of the grainstreated by the drying machine is uniform.

Description

technical field [0001] The invention relates to the technical field of dryers, in particular to a grain spreading device and a grain dryer. Background technique [0002] my country is the world's largest grain producer and consumer, with an annual total grain output of 500 million tons. According to statistics, the loss of my country's grain in the process of threshing, drying, storage, transportation, processing, and consumption after harvest is as high as 18%, far exceeding the 5% standard stipulated by the Food and Agriculture Organization of the United Nations. Among these losses, due to climatic reasons, grains are too late to dry or fail to reach safe water, causing moldy and germination losses of up to 5%. If calculated on the basis of an annual output of 500 million tons of grain, it is equivalent to 25 million tons of grain. Each person eats 500g of grain per day, which can be used by 68,000 people for one year. Therefore, the mechanization of grain drying is more...
