全膜双垄沟中耕除草培土机的设计与试验
Design and test of the weeding cultivator and hilling machine in double ridge furrow with whole film mulch
摘要
Abstract
Pointed to the problems as weeds in the seam of plastic-film edge ,without loosening soil in furrow bottom and hardly storage soil moisture ,high labor intensity and low working efficiency by artificial weeding and hilling under the cultivated pattern in double ridge furrow with whole plastic-film mulch in northwest China ,a new weeding cultivator and hilling machine in double ridge furrows with whole plastic-film mulch was designed out .This machine’s power was provided by the electric motor .The shovel wing of the double moldboard can be adjustable ,so the agronomic require-ments for different ridge width and hilling height can be met when cultivating ,also the whole operating procedure as loos-ening soil ,weeding and hilling can be completed in one time .The field test results showed that:The cleaning weeds rate in ridge furrow and injuring seeding rate were 97% and 1 .5% respectively ,the soil crushing rate was reached 78% ,the maximum hilling thickness was 113mm ,each operating indicator has total reached the design requirements ,and the effect of weeding and hilling were very good .关键词
