Efficient grain drying and sieving-in-one machine

Abstract

The invention discloses a high-efficiency integrated grain drying and screening machine, which comprises a support frame, a drum, a hot air pipe, and a sieve plate; the drum is rotatably arranged in the support frame; Connect the feeding pipe; one end of the hot air pipe is connected to the hot air blower, and the other end passes through the right rotating shaft from the center of the right rotating shaft of the drum and penetrates into the drum. The hot air pipe is densely arranged on the drum body. Air outlet; the hot air pipe is located at both ends of the tube body of the drum, and a group of straight rods are arranged, each group of straight rods has two and symmetrically distributed, and the end of the straight rod away from the hot air pipe is rotated and connected with a turning rod; The sieve plate is arranged below the feeding port. The invention can turn the grains during the grain drying process, avoid the accumulation of the grains, make the grains heated evenly, thereby ensuring the drying effect; meanwhile, it also has the function of screening.

Description

technical field [0001] The invention relates to an agricultural equipment, in particular to an efficient integrated grain drying and screening machine. Background technique [0002] The moisture content of freshly harvested grains is as high as 24%-32%, and in some parts of the Northeast, the harvested grains even have ice crystals. The safe storage moisture content of grain is about 14%. In order to quickly reduce the moisture content to a safe moisture content, people usually only use natural drying and other means. However, in rainy weather, if the drying is not timely, the grain will become moldy and deteriorate. [0003] Many of the existing grain drying devices are drum-type, which use the drum to drive the grain to roll and then use hot air to dry the grain, but the grain may accumulate together during the rotation of the drum, resulting in uneven heating of the grain and affecting the drying effect ; Most of the existing grain drying devices have a single function. ...
