Vibration Test and Analysis of No-Tillage Planter on the Maize Stubble Surface

Abstract:

In order to improve metering accuracy of air suction type no tillage seeder in maize stubble ground operation, the vibration parameters of air suction seed metering device of the machine are tested and analyzed. Using the method of orthogonal experiment, with forward speed, ditching depth, ridge direction as the influence factors by experimental study on vibration characteristics.The results showed that in no tillage corn field conditions,Stubble height 10-30cm, ridge height is 0-8cm, the soil moisture content 19.78%, The soil temperature 12.7oC. Effects of sowing machine vibration frequency spectrum of 3.46-12.30Hz and 33.50-50.50Hz, the two band spectrum reflects the vibration characteristic of planter operation in the field, can be used as indoor and virtual test selection of reference data. The test results show that: the main factors causing vertical vibration of no tillage seeder metering device is 90o ridge direction, i.e. the surface roughness is greater, causing the vibration of no tillage planter seeding device more. The second is a seeding machine forward speed for 7km/h, i.e., no tillage planter work faster, causing vibration the greater. Finally is the sowing depth, the factors and agronomic seeds, soil fertility, soil humidity etc. Agronomic requirements are closely related, for the smaller vibration effect of no tillage seeder metering device.
