Abstract
The utility model discloses a winnowing machine of small combine harvest, which comprises a thresh chamber and a winnowing device, wherein the bottom of the thresh chamber is provided with a collecting groove with arc section and a relative feeding screw conveyer, one end of the rotation shaft of the screw conveyer is connected with power. When screened particles fall into the collecting groove, the screw conveyer horizontally pushes the particles to an outlet to fall naturally, and since the falling area is at the winnowing area of the winnowing machine, chips and foreign materials are absorbed into an air tube by the winnowing machine to be discharged. The utility model is characterized in that the collecting groove comprises an in-chamber section and an out-chamber extension section, the outlet is at the end of the out-chamber extension section, therefore, the utility model can be engaged with a collecting container at the side of the utility model. The utility model has simple structure, reliable property, and high selecting efficiency, which can meet the demand of compact structure of small combine harvester.
Description
Affiliated technical field
The utility model relates to a kind of pneumatic separation device of baby combine.
Background technology
In the combine of prior art, how big-and-middle-sized machine is cleaned with the wind decontamination after the seed threshing is sieved, and by vertical screw feeder cereal is promoted the back from the grain export pack again, its complex structure, and the cost height, fault is many; (size little, do not have the space vertically is set) is difficult to be provided with pneumatic separator to baby combine because structural limitations, and the seed after the results needs increase production cost through selecting clean removal of impurities operation to process once more.How baby combine is provided with selection by winnowing removal of impurities mechanism, is the unsolved for many years difficult problem of the sector.
The utility model content
Problem to be solved in the utility model is to provide a kind of pneumatic separation device that is used for baby combine, and it is simple in structure, dependable performance, and the ratio of sorting and cleaning height meets the requirement of baby combine compact structure.
The utility model adopts following technical scheme: comprise threshing bin, pneumatic separator, described threshing bin bottom is provided with the defeated grain screw feeder that cross section is the grain getting groove of circular arc and matches, one end of described grain getting groove is a grain export, described pneumatic separator is an air draught type mechanism, described grain export is corresponding with the position, inlet scoop of air draught type mechanism, and an end of the rotating shaft of described defeated grain screw feeder connects power.Its principle is: the seed that sieves falls into the grain getting groove of threshing bin bottom; defeated grain screw feeder converges seed by the screw propulsion direction and laterally is pushed into grain export; the seed free-falling is to connecing in the container; because the selection by winnowing district that settles in an area and just in time be positioned at pneumatic separator under the seed, the chip impurity that is mixed in the seed is promptly sucked the airduct eliminating by pneumatic separator from the inlet scoop.
A kind of improvement is that described grain getting groove comprises extension outside storehouse inner segment and the storehouse, and described grain export is located at the end of extension outside the storehouse.This structure can be transported to seed the outer side of threshing bin, is placed with the frame that connects a container with the body sidepiece and is complementary.
The utility model is simple in structure, dependable performance, and the ratio of sorting and cleaning height meets the requirement of baby combine compact structure, has solved the difficult problem of baby combine selection by winnowing.
Marginal data
Below in conjunction with embodiment the utility model is described in further detail.
Fig. 1 is a kind of embodiment stereochemical structure of the utility model (complete machine part) schematic diagram.
Embodiment
As shown in Figure 1, a kind of embodiment of the utility model comprises threshing bin 1, pneumatic separator 2, described threshing bin 1 bottom is provided with the defeated grain screw feeder 4 that cross section is the grain getting groove 3 of circular arc and matches, one end of described grain getting groove 3 is a grain export 5, described pneumatic separator 2 is an air draught type mechanism, described grain export 5 is corresponding with 6 positions, inlet scoop of air draught type mechanism, and an end of the rotating shaft of described defeated grain screw feeder 4 connects power.Its principle is: the seed that sieves falls into the grain getting groove 3 of threshing bin 1 bottom; defeated grain screw feeder 4 converges seed by the screw propulsion direction and laterally is pushed into grain export 5; the seed free-falling is to connecing a container; because the selection by winnowing district that settles in an area and just in time be positioned at pneumatic separator under the seed, the chip impurity that is mixed in the seed promptly 5 is sucked airducts and gets rid of from the inlet scoop by pneumatic separator.
As shown in Figure 2, a kind of improvement is that described grain getting groove 3 comprises extension 7 outside storehouse inner segment and the storehouse, and described grain export 5 is located at the end of extension 7 outside the storehouse.This structure can be transported to seed threshing bin 1 an outer side, is placed with the frame that connects a container with the body sidepiece and is complementary.
The utility model is not limited to the concrete structure of the foregoing description, and the equivalent transformation of other homogeneous structure all falls in the utility model protection domain.
Claims (2)
