Description
Technical field
The invention belongs to the fault diagnosis technology field of harvester, and in particular to a kind of to be used for the receipts with longitudinal axial flow roller
The detection means of cutting mill failure.
Background technology
Taken off because for many years, the full-feeding combine harvester of domestic production is substantially all using the axial-flow type drum of lateral arrangement
From separator, this arrangement compact conformation, when feed quantity is smaller, transaction capabilities are preferable, but because threshing cylinder is horizontal
Arrangement, is limited, threshing cylinder can not be oversize, therefore, this kind of harvester generally existing problems with by locus：One is
Because threshing cylinder is shorter, threshing and separating capacity are restricted, and when feed quantity is slightly larger, entrainment loss can increase；Two be to tide
Wet crop and the de- crop adaptability of some hardly possiblies are poor；Three be material skewness on sorting screen surface, clear when feed quantity is larger
Select effect poor.Horizontal axial-flow combine harvester is due in structure, and its development space is subject to certain restrictions, market
Occupation rate is also in atrophy year by year.The major function of longitudinal axial flow roller is substitution straw walker, undertakes seed, the work of separation of stalk
Can, again with certain threshability, its separating capacity is strong, small to grain damage, especially de- to hardly possible and breakable a variety of works
Well adapting to property of thing.Recent years, crawler type longitudinal axial flow harvester was promoted quickly in China, is come from it and is adapted to very much
China's field road, field and agronomy mode, and with low cost, but its structure design is closely simultaneously.
Monitoring and diagnostic method both at home and abroad to harvester threshing drum failure, which is mainly, to be concentrated on to transverse-axis-flow threshing roll
The monitoring of cylinder rotating speed or torque signal and diagnosis aspect.Document " research of combined harvester plugging fault monitoring system " utilizes roller
Rotating speed slip diagnoses roller plugging fault.Document " the combine operation flow Research on fault diagnosis method based on PLC "
The method for diagnosing faults based on echo signal temporal changing tendencies is proposed, is realized using the difference equation of drum rotation speed discrete signal
The diagnosis and alarm of threshing cylinder failure, but these method generally existings the problem of low error of diagnostic accuracy is big, and work as
When blocking generation, in reduction of speed stopping process, monitored transient speed precision is too low, it is impossible to meet wanting for fault diagnosis
Ask.
