Problems solved by technology
[0002] Large-scale harvesters have cleaning mechanisms such as vibrating sieves, but when small-scale harvesters are simply cleaned through the threshing barrel, the broken straw is transported to the grain receiving port along the grain road, and the impurity rate is high. The proportion of grains is different to achieve preliminary cleaning, but because the grains will fall in a concentrated manner when they come out of the grain conveying channel, some straw will be mixed in the grains and fall with the grains, resulting in the high impurity rate of the grains after cleaning. Deep separation of straw from grain

The invention discloses a harvester cleaning device comprising a cleaning air duct provided with a tube-shaped outer wall, and the two ends of the cleaning air duct are open. One end is an air inlet opening, and the other end is an air outlet opening, and the cleaning air duct is communicated with an external suction fan through the air outlet opening. The area of the air outlet opening is smaller than that of the air inlet opening. The middle of the cleaning air duct is a cleaning part which is in a straight tube shape, and a cereal inlet is formed in one side of the cleaning part. A vortex generating mechanism is arranged on the air inlet opening and comprises multiple guide blades, one end of each guide blade is fastened on the air inlet opening, and the other end of each guide blade is located in an inner cavity of the cleaning air duct. An angle alpha is formed between the length direction of the guide blades and the axial direction of the cleaning air duct, and the angle alpha is smaller than 90 degrees, and inclination directions of all the guide blades are the same. The horizontal height of one end, away from the air inlet opening, of each guide blade is smaller than that of the grain inlet. The harvester cleaning device achieves depth separation between grain and straws in cereal and is simple in structure and good in cleaning effect.
Description
technical field [0001] The invention relates to the technical field of grain cleaning, in particular to a harvester cleaning device. Background technique [0002] Large-scale harvesters have cleaning mechanisms such as vibrating sieves, but when small-scale harvesters are simply cleaned through the threshing barrel, the broken straw is transported to the grain receiving port along the grain road, and the impurity rate is high. The proportion of grains is different to achieve preliminary cleaning, but because the grains will fall in a concentrated manner when they come out of the grain conveying channel, some straw will be mixed in the grains and fall with the grains, resulting in the high impurity rate of the grains after cleaning. Deep separation of straw from grain. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a harvester cleaning device, which realizes the deep separation of gra...
