In view of the present situation regarding cotton-stalk harvest in the Yangtze valley and the Huanghe valley, a collecting and adaptive spring holding feed mechanism for interweave cotton-stalks was developed. This combine harvester integrated pick-up, cutting, collection loading and unloading. The results indicated that a feed quantity of 1.52kg/s, average cut length of cotton-stalk of 92.11%, and average throughput of 0.94hm2/h could be achieved by the experiment, which satisfied the automatic request of cotton-stalk combine harvester. 
