当前棉花苗期中耕追肥作业多使用双翼通用铲与靴式施肥开沟器配合的配置,该配置形式在作业中存在如下缺点:1.开沟器通过性能差,易缠草,缠膜,壅土埋苗.2.在连茬棉田作业还易将埋于土壤表层的棉秆拉出,引起拉苗、伤苗.3.施肥开沟器距苗带远(20cm以上),开沟深度浅(5cm左右),肥料易在导肥管中堵塞,追肥作业质量差.4.中耕追肥作业班次效率低.为克服以上缺点,提高棉田中耕追肥作业质量和效率,我们将中耕追肥采用双翼通用铲与单圆盘式施肥开沟器配合的配置.开沟器用直径400mm的球面圆盘改制,圆盘中心镶嵌205轴承两套,与开沟器轴相接.开沟器轴与开沟器柄用固定卡联接,可调整开沟器与苗带的距离.开沟器柄用直径22mm的圆钢制成,用横梁固定卡与横梁联接,可调整圆盘转
The current cotton seedling tillage top dressing operations and more use of double-wing shovel shovel and boots with fertilizer opener configuration, the configuration in the operation there are the following disadvantages: 1 opener through poor performance, easy to wind grass, wrapping film, 壅Soil buried seedlings .2 in stubble cotton fieldwork is also easy to be buried in the soil surface cotton stalks pulled out, causing pull seedlings, injury seedlings .3 fertilizer opener away from the seedlings (20cm above), shallow depth of ditching (About 5cm), the fertilizer is easy to be blocked in the fattening pipe and the quality of top dressing is poor .4. The inefficiency of the top dressing and top dressing operation is inefficient. In order to overcome the above shortcomings and improve the quality and efficiency of top dressing and fertilizer operation in cotton field, With a single-disc fertilizer opener with the configuration.Drill with a diameter of 400mm spherical disc reorganization, the center of the disc inlaid with 205 sets of 205 bearings, and opener shaft phase .Disconnector shaft and opener handle With a fixed card connection, can adjust the distance between the opener and the seedling with a ditch handle made of round steel with a diameter of 22mm, with the crossbar fixed card and beam connection, adjustable disc rotation
