深松机械是对深层土壤进行疏松的机械,其目的是打破铧式犁耕翻或机组压碾土壤形成的坚硬的犁底层,以提高天然降雨入渗率,增加土壤蓄水保墒能力,从而为作物生长发育创造良好的水分应用环境,促进作物增产。(1)正确使用(1)深松铲入土角度的调整:在达到规定作业深度时,深松铲铲尖的最佳入土角为7°。入土角大,作业阻力加大,严重时不能入土;入土角小,深松深度不足,严重时也不能入土;调整时,应改变拖拉机中央拉杆长度,伸长中央拉杆,入土角减小;缩短中央拉杆,入土角增大。(2)机架与地表平行的调整:在作业状态时,要求机架 Deep pine machinery is to loosen the deep soil machinery, the purpose is to break the plow plow or press the hard crushing of the formation of the bottom layer of the plow to improve natural rainfall infiltration rate, increase soil water storage capacity, so as to Crop growth and development to create a good environment for water applications, and promote crop yield. (1) Correct use (1) Adjustment of deep-shovel excavation angle: The best penetration angle of deep-shovel shovel is 7 ° when the required working depth is reached. In case of serious depth, it can not be intruded. When adjusting, the length of the central pull rod of the tractor should be changed, and the central pull rod should be extended to reduce the entry angle. Shortening Central rod, into the soil increases. (2) parallel adjustment of the rack and the surface: In the operating state, the rack is required
