Study Of All-round Adjustable Subsoiler

As an important item of farming conservation tillage, the subsoiling technology takes a significant role on the agricultural persistent development. The subsoiling technology is an extremely reasonable cropping systems, it has proved over the years to be extremely popular with experts and farmers. And it is also a mechanized method which is essential for high-yield crops.In order to meet the northwest of Hebei province Bashang area comprehensive technology of drought resistance filling water needs, in view of the domestic and foreign existing deep loosening in some areas there mechanical work to a depth of less than requirements, big, soil and cultivation resistance problems such as large, according to Hebei agricultural university Zhangbei experiment stations in some areas of the soil for years of research, and put forward a new type of deep loosening mechanical-comprehensive deep loosening machine research subject, the research of contents include:(1) From the angle of statics plough and subsoiler is analyzed.(2) Design the two deep loosening plow part--by farming method based on markov Cardiff the loose the plough and wings type loose plow shovel.(3) Two of the deep loosening parts are made prototype plow, and in Hebei agricultural university ZhangBei experiment stations of the field test.The results of the study show that, compared with plough tillage, loose the plough and wings type no-till farming shovel in loose after all can guarantee a high straw coverage; At 0 to 20 cm soil hardness in all three similar; At 0 to 20 cm soil bulk density within the three phase almost; Loose the plough and wings type no-till farming in loose shovel deep stability achieved a higher level; And wings type loose tillage compared to shovel, loose the plough in farming, its the balance is poorer; Wings type loose plow shovel reasonable structure, stable performance, assignments of good quality, can guarantee a high crop straw coverage, under the premise of broken loose soil, break plough stratum, solve the existing deep loosening in Hebei Bashang area northwest machine after work for large quantity ditch, soil, etc. Subject research for northwest Hebei Bashang area conservation tillage, drought filling water of the technology of comprehensive and demonstrations, and provides a reliable deep loosening soil preparation machines.
