摘要: 针对大豆玉米带状复合种植模式下的现有喷药机无法分带定向喷施、适用性差的问题,设计一款适应于该模式、具有药物分带定向喷施、喷施高度分带可调节、防止药物发生带间飘移功能的自走式喷杆喷药机。根据4+2大豆玉米带状复合种植模式的农艺要求,确定整机机构方案;确定喷药机的喷杆高度调节装置、喷杆折叠装置和防飘移装置三个关键装置方案并进行结构设计。在灌云县大豆农场种植基地,对样机的高度调节性、可折叠性及防飘移性进行试验验证。结果表明,高度调节、折叠装置可以有效满足作业需求,防飘装置能够减少92.52%的液滴飘移,能够满足对玉米大豆的化学除草阶段及化学控旺阶段作业要求。

Abstract:  In order to solve the challenges of unable to perform targeted spraying and poor applicability in the strip intercropping of soybean and corn, A selfpropelled spray boom sprayer designed for this planting mode has been developed. This spray machine is capable of directional and heightadjustable spraying, preventing drift between rows. Firstly, based on the agricultural requirements of the new planting mode, the spraying plan is determined. Then, the specific parameters of the 4+2 planting mode in Jiangsu Province are used to determine the design of key devices for the spray machine, including the height adjustment device for the spray boom, the folding device for the spray boom, and the drift prevention device. Finally, soybeancorn strip intercropping spraying experiments are conducted at the soybean farm in Guanyun County. The prototypes height adjustment, folding device, and drift prevention performance are tested and verified. The results show that the height adjustment and folding devices can effectively carry out chemical weed control and chemical growth regulation for corn and soybean. The drift prevention device reduces liquid droplet drift by 92.52%.
