Technical field
The utility model relates to a kind of rice/wheat combine, relates in particular to a kind of whirlwind cleaning plant of rice/wheat combine, belongs to agricultural mechanical field.
Background technology
Cleaning plant is the important component part of rice wheat associating combine, and the quality of its performance directly affects the operation effectiveness of complete machine.At present, most of small-sized rice/wheat combines have been brought into use cyclonic separation cleaning plant.Cyclonic separation cleaning plant of the prior art " blower fan-vibratory sieve " cleaning plant has than before had very large improvement, but still has weak point, and major embodiment is as follows:
1. the rotating speed of induced-draught fan is fixed, and suction air volume is fixed, and then grain header gathers in situation and differs in operation process, sometimes crop cauline leaf is more, sometimes makes composition granule lighter, and crop maturity differs sometimes, in the face of various environment, cleaning plant impurities removing efficiency is not ideal;
2. cyclone separating tube design is unreasonable, and connecting pipe axial location designs in the center of cylinder, and like this, the wind-force producing due to induced-draught fan mainly concentrates in the axial location of cylinder, is easy to cause grain to be siphoned away by induced-draught fan, causes cleaning loss.
Utility model content
The utility model, according to the deficiencies in the prior art, provides a kind of rice/wheat combine whirlwind cleaning plant, regulates mouth and a cylinder inside spin structure by design air flow, can make rice wheat percentage of impurity significantly decline, and reduces cleaning loss.
The purpose of this utility model is achieved through the following technical solutions:
A kind of rice/wheat combine whirlwind cleaning plant, comprise induced-draught fan 1, separating pipe 2, cyclone separating tube 3 and lift grain conveyance conduit 4, wherein, cyclone separating tube 3 upper ends are connected with induced-draught fan 1 by separating pipe 2, in cyclone separating tube 3 lower end cones, be evenly arranged air admission hole 33, lift grain conveyance conduit 4 is connected with grain header discharging opening.
Separating pipe 2 is provided with air quantity near cyclone separating tube 3 one end and regulates mouth 22, component regulates mouth to regulate component according to the actual conditions of crop, reduce cleaning loss, separating pipe 2 middle parts are provided with telescopic plastic pipe 21, telescopic plastic pipe 21 can stretch within the scope of certain length, be conducive to adjust the installation site of blower fan, telescopic plastic pipe 21 links together by lock ring and separating pipe 2;
On the straight tube inwall of cyclone separating tube 3, be provided with protruding helical structure 32, the central axis position that this structure can effectively guarantee to come in through connecting cylinder 31 radially is wet, heavy grain thing is thrown to cyclone separating tube 3, improves impurities removing efficiency; Cyclone separating tube 3 straight tube sidewalls radially arc transition go out a connecting cylinder 31 radially, and radially connecting cylinder 31 is designed to integrative-structure with cylinder 3, and radially connecting cylinder 31 is affixed by rivet with lift grain conveyance conduit 4.
Further, described helical structure 32 helical angles are 25 °.
The beneficial effects of the utility model are:
1. the utility model is provided with air quantity and regulates mouth, can, according to the actual conditions of cereal, adjust flexibly air quantity, improves impurities removing efficiency, reduces cleaning loss.
2. the utility model is provided with helical structure, and this structure can effectively be thrown to cylinder shaft core position wet, heavy grain thing, improves impurities removing efficiency.
