合理地选择联合收割机的抗涝行走装置及改装结构参数,能大量减少人力、物力、财力的消耗,对提高联合收割机的效率和抗涝灾能力,减少收获损失都能起到积极的作用。1981年涝灾,我局对拖拉机、联合收割机的行走装置进行了23种改装,3940余台。通过这些改装,虽然也取得了一定效果,但由于缺乏正确的理论指导,走了一些弯路,造成了一些人力、物力及财力的损失。合理地选择抗涝行走装置(或改装结构参数)的关
Reasonably selecting the anti-flood walking device of the combine harvester and modifying the structure parameters can greatly reduce the manpower, material and financial resources consumption, and can play an active role in improving the efficiency of the combine harder and reducing the flood damage and reducing the harvesting loss. In flood disaster in 1981, our bureau made 23 kinds of refitting and more than 3940 sets of walking devices for tractors and combine harvesters. Through these modifications, although some achievements have been made, due to lack of proper theoretical guidance, some detours have been taken and some human, material and financial losses have been caused. Reasonable choice of anti-flood walking device (or modification of structural parameters) off
