Abstract
The utility model belongs to the field of agricultural machine parts, and particularly discloses a secondary cleaning mechanism of a combine harvester. The secondary cleaning mechanism of the combine harvester comprises a cyclone separator arranged on the combine harvester, an outer shell of the cyclone separator divided into a cylinder part and a cone part from top to bottom in the axial direction, and a helical impeller is arranged inside the cyclone separator in the axial direction. The cylinder part is provided with a vertical air outlet and a horizontal feeding opening, a discharging opening is formed in the lower end of the cone part, and an air hole is formed in the shell wall, close to the discharging opening, of the cone part. The feeding opening is connected with an output opening of a threshing device, and the air outlet is connected with an input opening of the threshing device. The secondary cleaning mechanism of the combine harvester is high in impurity removing precision, and good in cleaning effect.
Description
Technical field
The utility model belongs to the field of components of farm machinery.
Background technology
Dressing mechanism is the important component part of combine.The dressing mechanism of existing combine is divided into pneumatic jig combined type and simple and easy winnowing type according to version.Baby combine adopts winnowing type dressing mechanism conventionally, simple in structure but to clean effect not good enough, impure rate is up to 10% left and right, as documents (201120451788.X) discloses a kind of cleaning and sorting system and has used the grain combine of this cleaning and sorting system, the cyclone separating tube of this cleaning and sorting system comprises cylindrical shell, the interlude of cylindrical shell is column body segment, two sections are cone segments, the upper end of cylindrical shell is communicated with impurity adsorbing blower, column body segment is communicated with winnow, column body segment is communicated with winnow by separating pipe, the sidewall away from tubular axis of separating pipe protrudes the column body segment barrel of cylindrical shell, on the cone segments sidewall of cylindrical shell hypomere, interval is laid with ventilation hole.
The shortcoming of such scheme is: the cereal after cleaning is directly exported, impurity can be blown, but the impurity of the larger particles being mingled with in cereal (as handstone) etc. can enter in the cereal of output, the not too full cereal of particle is blown out because too gently regard impurity, so only carry out the dressing mechanism of single selection by winnowing, removal of impurities is thorough not or removal of impurities error is large, cleans poor effect.
Utility model content
The utility model is intended to provide the secondary Qing Xuan mechanism that a kind of removal of impurities precision is high, clean effective combine.
The purpose of this utility model can reach by following measures: the secondary Qing Xuan mechanism of combine, comprise for being arranged on the cyclone separator on combine, cyclone separator shell is divided into cylindrical portion and conus portion vertically from top to bottom, and cyclone separator inside is axially arranged with helical runner.Cylindrical portion is provided with air outlet straight up and horizontal charging aperture, and it is discharging opening that conus portion is provided with lower end, and conus portion is having air vent near on the shell wall of discharging opening.Above-mentioned charging aperture is connected with thrasher delivery outlet, and air outlet is connected with the input port of thrasher.
Technique scheme difference with the prior art is: in the utility model, after helical runner rotation starts, from air vent air amount, and in cyclone separator, form swirling eddy, cereal to be cleaned is from charging aperture tangential feed, cereal is thrown toward the inwall of cyclone separator under the drive of swirling eddy, and slips into conus portion along inwall under Action of Gravity Field, and exports along discharging opening; And the utility model different from traditional dressing mechanism structure be, air outlet is connected with the input port of thrasher, be that air-flow after cyclone separator separates will again enter thrasher and carry out sorting, clean along with some not too full cereal-granules of air motion can carry out secondary like this, prevent that it is used as magazine and is discharged from.Thereby improve the accuracy rate of removal of impurities, improve the effect of cleaning.
Further, described cyclone separator inside is provided with the filter screen that is positioned at helical runner top, can roughly select cereal, prevents that the impurity of larger particles from exporting from discharging opening.
Further, described charging aperture is connected by stirring cage conveyer with thrasher, improves transfer efficiency, can rapidly cereal be transported to the charging aperture of the cyclone separator that horizontal level is higher from the lower thrasher of horizontal level.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation that the secondary of the utility model combine please select mechanism for implementing example.
Embodiment
As shown in Figure 1: the secondary Qing Xuan mechanism of combine, main body is cyclone separator, this cyclone separator is arranged on combine, the shell of this cyclonic separation is divided into cylindrical portion 1 and conus portion 2 vertically under upper, the inside of cyclone separator is provided with screw impeller along axis, and impeller is driven by motor.
In cylindrical portion 1, have horizontal charging aperture, this charging aperture is connected by stirring cage conveyer 3 with the thrasher of combining, and cereal through being delivered to charging aperture by stirring cage conveyer 3, enters cylindrical portion 1 inside at tangent line after thrasher.Cylindrical portion 1 inside is provided with steel wire screen pack along its cross section, this steel wire screen pack is positioned at impeller top, cereal enters the interior rear elder generation of cylindrical portion 1 and is filtered and roughly selected by steel wire screen pack, and the impurity of larger particles is stayed on steel wire screen pack, and cereal and less impurity are able to by steel wire screen pack.The top of cylindrical portion 1 has air outlet 4, and this air outlet 4 is connected by centrifugal blower with the charging aperture of thrasher.
Conus portion 2 lower ends are discharging opening, have some air vents near discharging opening.Helical runner in cyclone separator produces swirling eddy while rotation, cereal is thrown toward the inwall of cyclone separator under the drive of swirling eddy, and slip into conus portion 2 along inwall under Action of Gravity Field, and export along discharging opening, less impurity can be along with air-flow rises, and again enter thrasher from air outlet 34 and carry out secondary and clean.
The foregoing is only the detailed description of the utility model preferred embodiment, be not used for limiting the utility model, the embodiment of all similar variations of doing according to creation spirit of the present utility model, all should be contained among the utility model protection domain.
