Design and Experiment of Crawler Type Non-stop Baling and Harvesting Integrated Machine

Crawler type non-stop baling and harvesting integrated machine has functions such as continuous harvesting, multi-level conveying, shredding and throwing, chain climbing conveying and feeding, and non-stop bundling and forming for woody plants such as Caragana, Salix psammophila, and Hybrid broussonetia．Key components were researched and designed, such as a tracked hydraulic variable displacement walking chassis and a non-stop round bundling device．A dual disc saw cutting table device, a multi roller feeding device, a combined cutting drum device, and an adaptive control system that automatically matches load feeding with operating speed, were integrated and applied．Performance tests have shown that developed tracked walking chassis could adapt to requirements of 8 t load driving and 20° climbing．The entire machine's walking, cutting, conveying, chain climbing, feeding and bundling processes were smooth, and size of round bundle formed was Φ 900 mm × 1 000 mm, with regular bundle shape, average bundle weight of 220 kg/bundle（fresh quality of caragana）, bundling rate of 98.2%, loss rate of 5.5%, average operating speed from 3 km/h to 4 km/h, and maximum operating speed of 5.9 km/h．The average cutting height after operation wass less than 8 cm, and operating production efficiency was 0.66 hm²/h．It could achieve integrated harvesting, conveying, and continuous non-stop operation．
