Description
Technical field
The present invention relates to agricultural cutter field, particularly relate to a kind of community rice wheat combine harvester air-sweeping type header device.
Background technology
Oryza sativa L., new variety of wheat educate in numerous process, community contrast experiment to be carried out, after the yield of this kind, lodging tolerance, diseases and insect pests resistance etc. are made objectively evaluation, could launch popularization.And community results are the final links of field breeding experiment, its results quality directly influences the accuracy of experimental result.But there is bigger difference with land for growing field crops results in community results, in community gathers in the crops, single hillslope processes area is little, and the quantity of hillslope processes is many, and often harvesting a community to carry out seed cleaning to harvester, it is to avoid mixing of different districts seed.
The community results of current China rely primarily on hand harvest, the stagewise results of thresing machine threshing and cleaning are main, and labor intensity is big, and indirect loss is big, causes experimental data distortion.In the last few years, the domestic community rice wheat combine harvester developing two kinds of forms.A kind of is from the community wheat crops united reaper that traditional harvest machine improves, and relies on the negative pressure that hulling disk produces that from the ceding of Taiwan, material is sucked threshing cylinder, but may result in blocking when material ratio is moister.And the ceding of Taiwan does not adopt the measure of easy clear, for instance install scavenger system etc. additional, the ceding of Taiwan has seed residual, is not easily cleaned.Another kind is aspiration comb-threshing-type seeds in combination harvester, adopts the ceding of Taiwan of aspiration comb-threshing-type, and this ceding of Taiwan has the features such as feed quantity is little, power consumption is few, but there is seed spatter loss, the de-loss of leakage in the de-process of comb, rewinds loss, and the rate that causes damage is too high.Owing to domestic existing community rice wheat combine harvester exists clear difficulty, loses big problem, cause there is no spread.The ceding of Taiwan is as the important process parts of community rice wheat combine harvester, and its performance directly influences the working performance of complete machine, loss rate, residual quantity etc..So the novel ceding of Taiwan of design noresidue, low loss rate is very necessary.
Summary of the invention
The problem that it is an object of the invention to there is seed residual for the rice wheat combine harvester ceding of Taiwan of above-mentioned community, loss rate is big, it is proposed to a kind of community rice wheat combine harvester air-sweeping type header device.
To achieve these goals, the technical scheme is that community rice wheat combine harvester air-sweeping type header device, including positive air flow Chui He mechanism, side airflow cleaning mechanism, blow standing grain air-flow governor motion, spiral winnows screw feeder, cutter, nearside divider, blower fan etc.；Described cutter is arranged on bottom the front side of ceding of Taiwan frame, for cutting the stem stalk blown down by positive top blast standing grain air-flow；Described nearside divider is positioned at both sides, ceding of Taiwan frame front end, for a point standing grain.

Detailed description of the invention
Community rice wheat combine harvester air-sweeping type header device, by positive air flow Chui He mechanism, side airflow cleaning mechanism, blow standing grain air-flow governor motion, screw feeder 8 winnowed by cutter 3, nearside divider 5, spiral, blower fan 14 forms.Wherein positive air flow Chui He mechanism is made up of air-flow house steward 4, airflow manifold 6, flexible pipe 10, blast regulator 11；Side airflow cleaning mechanism is made up of side airflow pipe 1, ceding of Taiwan frame 2, valve 12, airduct 13；Blow standing grain air-flow governor motion and include adjusting handle 15, base 16, leading screw 17, universal joint 18, sleeve 19, levelling lever 20.The two ends of described air-flow house steward 4 are placed in the annulus of levelling lever 20, are totally positioned at the front upper place of ceding of Taiwan frame 2, are fixed with levelling lever 20 by alignment pin 21, and right-hand member is connected with flexible pipe 10, and flexible pipe 10 is connected with blower fan 14；Described airflow manifold 6 is equally spaced to be positioned on air-flow house steward 4, and blast regulator 11 is positioned in flexible pipe 10；Having square airflow hole bottom described ceding of Taiwan frame 2 left and right sides, side airflow pipe 1 is positioned at bottom the left and right sides of ceding of Taiwan frame 2, is connected with the airflow hole of ceding of Taiwan frame 2, and its air inlet is connected with airduct 13, and airduct 13 has valve 12, and airduct 13 is connected with flexible pipe 10；Described base 16 is placed in above the left and right sides of ceding of Taiwan frame 2, and leading screw 17 is vertical with base 16, and adjusting handle 15 is connected with leading screw 17 by trip bolt.Leading screw 17 is connected with universal joint 18 bottom, and universal joint 18 is connected by bolt with sleeve 19, and levelling lever 20 is placed in sleeve 19, and is fixed by trip bolt.Alignment pin 21 is positioned in the aperture on the annulus of levelling lever 20 and air-flow house steward 4.
When harvesting, first gas Liu Dao optimum state is regulated according to the characteristic that Oryza sativa L., Semen Tritici aestivi are different by blast regulator 11, the positive top blast standing grain air-flow that field rice wheat is penetrated from airflow manifold 6 when being kept upright blows down in the ceding of Taiwan, then being cut off by cutter 3, while harvesting, the seed in the ceding of Taiwan, cane are winnowed toward spiral by positive air flow and are blowed below screw feeder again；The material cut down spiral winnow screw feeder 8 effect under toward middle mobile, raise under the effect of impact of blade 7 into spout 9.Behind harvesting Wan Yige community, opening valve 12, side airflow cleaning mechanism is started working, and seed, cane that bottom ceding of Taiwan frame 2, ceding of Taiwan both sides are remained by the air-flow of square airflow hole injection blow below blade.Thus ensure that the ceding of Taiwan in the course of the work is without seed residual, easy to clean.
The effect blowing standing grain air-flow governor motion is to regulate the air-flow house steward 4 angle from the horizontal and vertical distance of the ceding of Taiwan, adjustment airflow manifold 6 according to different rice wheat varieties.Its work process is: by rotating adjusting handle 15 adjusting screw 17 at the height of vertical direction, with the effect of universal joint, levelling lever will not concomitant rotation, such that it is able to regulate the air-flow house steward 4 vertical dimension from the ceding of Taiwan；By moving left and right levelling lever, it is possible to regulate the air-flow house steward 4 horizontal range from the ceding of Taiwan.The aperture of the aperture on levelling lever annulus and air-flow house steward two ends can be fixed by alignment pin 21, regulate the angle of airflow manifold 6 with this.It is achieved thereby that air-flow house steward regulates from the step-less adjustment of ceding of Taiwan horizontal and vertical distance and the level that has of airflow manifold 6 angle.
