Abstract
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
The present invention relates to grain cleaning technical field, relate in particular to a kind of cleaning and sorting machine for harvester.
Background technology
Large-scale grain header has the dressing mechanisms such as reciprocating sieve while cleaning, but when small harvester is simply cleaned through thrashing cylinder, crushing straw is transported to and connects grain mouth with way to move grains, percentage of impurity is high, though through fan induced draught, the proportion that utilizes stalk and cereal is different and reach and tentatively clean, but because can becoming to concentrate when carrying way to move grains out, cereal falls, part stalk can be mixed in cereal, fall with cereal, the percentage of impurity that causes cleaning rear cereal is too high, fails stalk to separate with the cereal degree of depth.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of cleaning and sorting machine for harvester, to realize and grain in cereal and stalk are carried out to the degree of depth separated, it is simple in structure, cleans effective.
A kind of cleaning and sorting machine for harvester that the present invention proposes, comprise and clean air duct, the described air duct of cleaning has cylindrical outer wall, the described air duct both ends open of cleaning, wherein, one end is air intake opening, the other end is air-out opening, and be communicated with outside air exhauster by described air-out opening, the area of described air-out opening is less than the area of described air intake opening, the described air duct middle part of cleaning is the portion of cleaning, the described portion of cleaning is that straight-tube shape and one side are provided with cereal entrance, described air intake opening part is provided with vortex and generates mechanism, described vortex generates mechanism and comprises some guide vanes, one end of described guide vane is fastened on described air intake opening part, and described in being arranged in, cleans the other end air duct inner chamber, the length direction of described guide vane with described in clean air duct axial direction become α angle and α <90 °, the incline direction of each described guide vane is identical, described guide vane away from the level height of described air intake opening one end lower than described cereal entrance.
Preferably, described in, clean air duct middle part and be provided with airtight watch window.
Preferably, 30 °≤α angle≤60 °.
Preferably, the quantity of described guide vane is 2, and described guide vane is evenly distributed.
Preferably, described watch window and described cereal entrance are oppositely arranged.
In the present invention, grain conveying device by cereal entrance with clean air duct and be communicated with, cereal enters in the inner chamber of cleaning air duct and cleans portion through cereal entrance, pass into air-flow by air intake opening to cleaning in air duct inner chamber, air-flow generates mechanism through vortex and forms eddy airstream, the cereal of cleaning in portion is dispersed and forms of short duration suspension in the effect of eddy airstream, the stalk that density is less flies out from air-out opening with eddy airstream, the grain that density is larger drops from air intake opening under Action of Gravity Field, thereby realize separating of stalk and grain, complete cleaning of cereal, wherein, vortex generates mechanism design for to be made up of some guide vanes, it is simple in structure, eddy airstream is easy to form and adjust, the portion of cleaning is designed to straight-tube shape and is also further conducive to improve the stability of eddy airstream in the portion of cleaning, clean effect thereby improve.
