Abstract
Recently a series of mainly on reducing plough ,avoiding plough and protecting plough and compound-mechanized technique come to use both in home and abroad.
For saving power consumption these methods are adopted and popularized widely. The technology of ploughing in line and mincing straw in line is applied in this work machine. It can reduce the stirring quantity, and cover the earth¡¯s surface with straw and decrease the erosion of wind and rain ,improve the soil fertility and the ability of resisting dry, meanwhile decrease the plough and running off of the soil. The plough unit works in the form of coordination of moving knives and static knives, so it can mince the straw and grass , and the removing axle is reversed then can uproot , saving 30 percent power consumption. And it is necessary to countervail the rising cost because the price of crude oil is rising ,and it is good for the paddy resisting to fall over .
Sowing machinery require higher adaptability so that can meet all kinds of working demand such as in time ,at rational and supplying a good condition to the paddy sow. It is more accurate efficient than man-hand and create a good condition of administrator superintendence
Sow in line is a method of sowing seed into soil according to distance and quantity of required£¬then cover the seed with soil. The form of the seed discharged is stream of water. This technique is mainly used in paddy, wheat, broomcorn and so on.
Key words: mince in line plough in line sow in line
