Grain spreading device and grain dryer

Abstract

The application provides a grain throwing device, including a bottom plate, and a guide assembly arranged on the bottom plate for guiding the grain; the guide assembly includes a guide plate, and the guide plate includes an arc section and a straight section, and the extension direction of the straight section is The direction of the tangent at the end of the arc segment. The device can evenly sprinkle the grains and evenly scatter them into the drying room, effectively solve the problem of uneven accumulation of grains in the drying room, improve the effective utilization of the drying room space and the drying efficiency of the grains, and make the grains dry in the drying room. During the process, the heating is uniform and the moisture content is uniform. In addition, the present invention also provides a grain dryer, which includes any one of the above-mentioned grain spreading devices. The grain dryer provided by the invention can evenly dry the grain, the space utilization rate of the drying chamber is high, the drying amount per unit time is high, and the grain can be heated evenly during the drying process. The moisture content of the grain processed by the dryer 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...
