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 and grain in grain

The invention discloses a harvester cleaning system comprising a cleaning air duct, a suction fan and a grain bag. The cleaning air duct is provide with a tube-shaped outer wall, 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. The suction fan is communicated with the cleaning air duct through the air outlet opening, the grain bag is located below the air inlet opening, and 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 in a straight tube shape, and a cereal inlet is formed in one side of the cleaning part. A vortex part is arranged between the cleaning part and the air inlet opening and is in a conical tube shape, a vortex generating mechanism is arranged in an inner cavity of the cleaning air duct 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 at the intersecting position of the cleaning part and the vortex part. All the guide blades are tightly attached to the tube-shaped outer wall and bent in the length direction, the bent directions of all the guide blades are accordant, and the horizontal height of one end, away from the air inlet opening, of each guide blade is smaller than that of the grain inlet.
Description
technical field [0001] The invention relates to the technical field of grain cleaning, in particular to a harvester cleaning system. 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. Deeply separate the stalks and grains in the grain. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes a harvester cleaning system, which realizes de...
