Design and Experiment of 1JH-440 Fine Shredded Corn Straw Returning Machine
The sowing quality has been put forward higher requirements with the implementation of high and new agricultural technology in production.However,the combined soil preparation and seeding machine at present could not fully meet production needs.In this connection,a double-press seeding machine with a wide seeding belt was designed in this paper.The whole structure of the machine was composed of two parts,a dynamic palladium with full suspension and a precision seeder with folding suspension.The integration of operation was carried out by the Power-rake and the seeder with single shaping monomer.The double suppression of wide wheat seedling belt was realized and the uniformity of sowing depth was improved by flattening the soil before sowing and suppressing the seedling belt after sowing.The results of field test and late emergence showed that,the variation coefficient of sowing uniformity of this seeder was 14.2％,the qualified rate of sowing was 93.6％,the bulk density of the soil in-creased by 0.193 g/cm3 compared with before,the emergence was good,all performance indexes and operation pa-rameters could meet the requirements of national standards and regional agronomic requirements.
