Corn harvester quality appraisal

corn harvester is an agricultural machinery used to harvest, transport and crush corn stalks and collect mature corn kernels. It consists of cutter, conveyor, crusher, feeder, screening system and other parts. Its working principle is to harvest the corn stalks through the collector, then transport the corn stalks to the cutter, and after cutting, transport them to the crusher for further crushing, and finally collect the mature corn kernels.

quality product dispute situation:
According to the situation reported by the client and the information provided, the client purchased a corn harvester from a certain company. A fire broke out while the client was driving the harvester to harvest corn, causing the corn he planted to be burned.
The cause of the fire was that an open flame appeared at the air outlet of the corn harvester during harvesting, igniting the surrounding corn and causing a disaster. The client hopes to conduct a quality analysis on whether the "corn harvester" involved had quality problems that caused the fire.
quality analysis results: The
quality analysis expert group discussed the relevant information, on-site investigation and inspection of the "corn harvester" involved, and made a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
(1) The corn harvester has quality problems such as the insulation layer at the horizontal end of the exhaust pipe is not tightly wrapped, there is local high temperature, and the engine exhaust pipe nozzle is set too low to easily ignite corn stems and leaves.
(2) There is a causal relationship between the above quality problems of the corn harvester and the cause of the fire.
