There are too many failures of rice harvesters, and blind cost reduction leads to reduced reliability, what should we do?

Full feeding rice harvester can complete harvesting, threshing, sorting and crushing straw and other operations at one time, with high production efficiency, low labor intensity, good operation quality, small harvest grain loss and other obvious advantages, in recent years, full feeding rice machine development rapidly, market share is increasing, today we will talk about the rice machine harvesting process of problems and countermeasures.
According to market research, the average failure rate of rice machines in use exceeds 300%, and some rice machine failure rates are even as high as 1300%, in addition to the common loss in rice machine operations, high impurity rate, rice production and other soft faults, belt burning, a horizontal auger shaft break, variable belt box damage, insufficient power, injector failure, grain unloading motor does not work, grass crusher damage, fan shaft breakage, steering cylinder damage, Hardware failures such as secondary horizontal auger shaft breakage, chain breakage, cutter breakage, gear pump oil leakage abound. Once a harvester user helplessly said: I bought the harvester to buy a master, how to serve, the failure I thought of happened, the failure I didn't think of also happened; There are only failures that you can't think of, and there are no failures that can't happen. The failure in the operation of the rice harvester, in addition to improper use and improper adjustment by the user, has a lot to do with the manufacturer's pursuit of profit, cost reduction, low requirements for the quality of parts, poor control, inadequate assembly, and improper assembly adjustment.
Some insiders have joked that many quality problems are reduced costs, at first listen to do not understand, carefully ponder, in fact, this statement is quite reasonable, some enterprises in the industry are extremely strict on cost control, and even to a large part of the research institute's work is not used to develop new products, but to study how to complete the assigned cost reduction task, remember that there have been enterprises in order to reduce costs, resulting in the strength of the harvester frame is not enough to cause batch cracking in the use of large frames, Extreme cases that had to be re-strengthened or even replaced one by one. After such a serious quality problem appears, it will have a great negative impact on the brand image of the enterprise, and at the same time will produce a large number of direct costs, such as: spare parts costs, labor costs, new parts transportation costs, old parts transportation costs, claim costs, etc. Therefore, manufacturers should strictly control the quality when producing rice machines, ensure the reliability and durability of each part on the harvester, and improve the level of assembly technology.
Secondly, the training of the rice machine operator is not in place, and the machine operator can only operate the machine tool simply, and the operation level is not too high. Harvester is a more complex tool, in the harvesting operation need to be according to crop varieties, maturity, dry and wet degree, yield on the harvester air volume, speed, speed, drum gap, auger gap and other series of adjustment, the process of harvester operation is the process of continuous adjustment according to the actual operation situation, if the operator training is not in place, the operator is not skilled in adjustment, will cause improper adjustment in the operation, affect the operation effect, there will be a series of failures such as loss in the operation, more miscellaneous and more meters.
Thirdly, when the user uses the harvester, the harvester is not cleaned and maintained in time after each use is completed, resulting in premature fatigue, aging and damage of the machine parts during the storage of the harvester, which affects the use. After each use of the harvester, it should be cleaned up and maintained in time, and it should be stored and stored when not used for a long time.
For some hilly areas, existing plots of land are not suitable for existing rice harvesting machinery. To realize the agricultural mechanization of hilly and mountainous areas, not only agricultural machinery, but also suitable for agricultural machinery operation, the environment, it is necessary to carry out mechanization transformation work on the plots that were originally not suitable for agricultural machinery operation, at present, the mechanization transformation of farmland in hilly mountainous areas has become the national key policy measures to accelerate the transformation and upgrading of agricultural mechanization.
At present, the domestic harvester is mainly mechanized, but the degree of automation is not high enough, and the operator may have operational errors and potential safety hazards in the environment of driving the harvester for high-intensity operation. In the future harvester research and development and manufacturing process, we should strengthen the harvester automation and intelligent research work, improve the automation and intelligence level of the harvester, use intelligent data monitoring and collection and other information technology to achieve threshing drum load monitoring, harvesting operation quality monitoring, automatic guidance and automatic driving and other functions.
I hope that our rice harvester will become better and better, the reliability will be higher and higher, the failure rate will be lower and lower, and it will better serve our agricultural production.
