Abstract
|
Potato mechanized planting pipe laying process , the drip tape laying depth unstable , often due to the thin wall drip tape buried soil compression cause blockages , so that the drip irrigation system is not working properly . Walking speed of the unit decreases with volume roll tight relaxation , the laying process unreliable . In response to these problems , the use of three-dimensional modeling software SolidWorks 2CMG-4 potato planter drip tape laying device based on the design of the set of the planter supporting the use of ground contour role the shallow drip tape laying device . Adjusted by the test apparatus in the 0cm 2.5cm, 5cm buried depth case where the measurement data obtained , to adjust the depth and the actual laying depth difference increases with the increase of the depth to be buried , The device is able to achieve a shallow drip tape laying, effective solution to drip tape laying depth control problem . Drip tape by the guide block in the original laying on the apparatus and the test apparatus , whether to use the tape roll clamp , whether to use a case of different combinations of the three factors of the fixing bolt , measuring the tension of the drip tape , the analytical measurement data obtained these three the impact of factors on the drip tape tension . Calculate the moment of inertia of the coil draw the drip with brake time / overflow amount of brake drag torque into an anti- correlation . 5N ยท m moment of resistance , the radius of the coil by 240mm change to 70mm process , drip tape tension by 20.8N changes to 71.4N ; drip tape tension and with volume radius inverse relationship ; design based on the above analysis of the drip tape tension the adjustment mechanism , improving the reliability of the process of laying .
