Design and Experiment of Key Components of Air-suction Garlic Seeder
摘要
Abstract
In view of the fact that the current garlic sowing method relied on manual labor,the efficiency was low and easy to miss or reseed,an air-suction garlic seeding machine was designed to improve the efficiency and accuracy of garlic see-ding.And the garlic seeds could be effectively evenly disseminated into the soil by using the principle of negative pressure through the air-suction seed-metering device,and the device could complete the functions of ditching,seed suction,seed rowing,soil covering and depth limiting at one time.In this paper,the overall structure of the air-suction garlic seeder was expounded,and the structural design and theoretical analysis of its key components,including imitation ditching de-vice,seed removal device,soil covering device and depth limiting device was carried out.The rotation speed of the dis-turbing cam,the rotation speed of the seed tray and the negative pressure of the air chamber were taken as the test factors,the sowing qualification index,reseeding index and missed seeding index were taken as the evaluation criteria,and the three-factor and three-level orthogonal tests were carried out.The mathematical regression equation and response surface model were constructed by Design-Expert 13 software,and the influence of each parameter on the sowing qualification rate index was analyzed.The optimal working combination parameters of the seed metering device were determined by using the software optimization module as follows:the negative pressure of the air chamber was 10.5 kPa,the rotation speed of the seed tray was 10 r/min,the rotation speed of the cam was 225 r/min.The field test showed that the sowing qualification index of the machine was 88.4%,the reseeding index was 2.9%,and the missed seeding index was 8.7%,referring to the national standard for sowing GB/T 6973-2005 Test Method for Single Seed(Precision)Seeder,which met the relevant national standards and agronomic requirements for garlic planting,and could provide reference for the design of air-suction garlic seeder.关键词
