Abstract

The invention discloses a grain drying bin with hidden air ducts. The grain drying bin comprises a bin body, a hot-blast stove, and an induced draft fan, wherein the bin body comprises two inlet and outlet air ducts, and is used for accommodating to-be-dried grain; the hot-blast stove is connected to one side of the bin body through one inlet and outlet air duct, and is used for introducing a hot blast into the drying bin; the induced draft fan is connected to the other side of the bin body through the other inlet and outlet air duct, and is used for pumping out the hot blast in the bin body; the bin body is of an interlayer structure, a horizontal main air duct and vertical hidden air ducts, the horizontal main air duct is connected with the two inlet and outlet air ducts, and the plurality of vertical hidden air ducts are evenly distributed in an interlayer of two side surfaces of the bin body; the upper ends of the vertical hidden air ducts are sealed, and the lower ends of the vertical hidden air ducts are communicated with the horizontal main air duct; vent holes are evenly distributed in the side, close to the grain, of each vertical hidden air duct, and are used for introducing a hot blast into the grain. The grain drying bin with the hidden air ducts realizes the combination of drying and storage, reduces the cost for transportation, and has the advantage of reducing middle loss.

Description

technical field

[0001] The invention relates to the technical fields of agricultural machinery engineering, agricultural product processing and storage engineering, and grain and oil storage engineering. More specifically, the present invention relates to a concealed air duct grain drying bin and a control method thereof. Background technique

[0002] In the field of agricultural production, grain storage is an important link. If it is not kept properly, the grain will suffer from mildew, insect damage, rodent damage, and food quality decline, which will cause major economic losses to grain and agriculture, and food security is a national strategy. , so the links of grain storage, drying, and storage are attached great importance from farmers to the country. In the past, farmers stored grain, which was simply packed in sacks and placed in the house, and some were placed in the cellar. Drying and ventilation could not be guaranteed. Every year, grains were mildewed and rats ...
