Design and experiment of suspended rotary tillage ridge and film mulching machine

Considering the planting mode and agronomics requirements of the existing facilities, the high-power rototilling ridge hoisting and lamination machine is difficult to operate in the greenhouse of the facility, and the small hanging rotary ridge raiser has technical problems such as insufficient horsepower. This paper designs the hanging rotary tillage ridging and film - covering machine. The machine realizes a single operation process to complete rotary tillage, ridging, drip irrigation, film laying and film edge covering soil suppression and other mechanized compound operations. The innovatively designed adjustable ridging device of this machine can steplessly adjust the size of the ridge. The ridge height after operation of the machine is 25-35 cm, the ridge width is 70-80 cm, the ridge shape is arc-shaped, the size is adjustable, and the operation efficiency is improved being 0.17-0.23 hectares/hour, the machine driving speed is set at low speed 1 gear. The machine has high operating efficiency, the arc-shaped ridge body is uniform and compact. the ridge body has a large lighting surface, the film is tightly laid, and it is close to the ridge surface without wrinkling. By test data analysis, the tillage depth stability is 93%, the ridge height qualified rate is 100%, the ridge width qualified rate is 85%, the ridge spacing qualified rate is 95%, the film edge covered soil thickness is 40 mm, the working efficiency is 0.802 hm2/h, the fuel consumption per hectare is 9.02 kg center dot h/m2, and the three shifts work without fault. To sum up, it meets the agronomic requirements of ridging and film planting.
