| The rice is very important in our country food product. There are 60% population regard rice as the staple food in our country. Rice plants area share 30.63% of the world in our country, the total yield occupies first. Now, our country agriculture faces the historical period change from the traditional agriculture period to modern agriculture. The rice plant mechanization is the most part.Seed sowing device is core of Spacing drill, the guide of sowing equality degree decides the capacity of sowing. How to increase seed sowing device work capability is a problem at home and external.Suction planter is advanced seed sowing device. With its special advantage, used for sowing cultivation crop, used for sowing rice bud is little accounted. This paper aim at the suction seed sowing device sow rice bud proceeded a lot of trial research.At first, I proceeded the dynamics analysis to seed sowing device absorb seed process. Dividing seed sowing device into fill the area and take seed area, Aiming at its different function, analyze the seed to suffer the dint circumstance in two districts, and put forward the bore absorb the seed term. The seed was absorbed by the bore and need vacuum size. According to analysis dint result of the seed, affect suction seed dependable factor is vacuum, disk rate, suction area, and seed characteristics etc.To improve the rice vertical disk seed sowing device function, find out affect sow key factor. According to the country GB-6973-86to measures the sowing seed function. At experiment platform of seed sowing device, passing changes the different parameter of the seed sowing device dish, turn rate, rate of ribbon etc. factor to proceeded the contrast experiments. Influence the sowing function the main factors are bore diameter, vacuum etc. factor of the dish, and find out three with qualified index, leak index and repeat sowing index the relation. The seed sowing device function experiments the enunciation, increasing the path that seed sowing device function is a reasonable air chamber and bore diameter, bore number, turning rate, Vacuum degree reasonable matches.I used ANSYS/ FLOTRAN to simulate analysis air of seed sowing device suction room in my paper. How to use software of ANSYS set up the mold, mesh division, add to the boundaryterm etc. proceeded detailed, description and understand easily, and the value imitates the result contrasts with experiment data, fitting together better. ANSYS can imitate availably the air room flow, pressure and velocity field distribution, this benefits to the space drill function analysis, offering the theories according to optimum.I applied normal experiment method to experiment at experiment platform of seed sowing device. Experiment results indicate that space drill function is good to suitable for super-speed homework, and the average qualified index is of 80.34%. Comparing with current machine type seed sowing device the function, the grain distance eligibility index increases 20 percentage. Passing the analysis decided the main factor, and passing the square analysis to examine the analysis results.The above research contents are the rice bud sows space drill principium result .The other function needs further research. |
