Description
Technical field
The invention belongs to the design of combined harvester cleaning plant and Self Adaptive Control field, be specifically related to a kind of combined harvester cleaning loss percentage adaptive controller and method.
Background technology
Cleaning plant is combined harvester " digestive system ", and being affects overall operation quality, efficiency and adaptive core work parts.The rice combine that in China market, recoverable amount is maximum adopts traditional Type Airflow Rice-Wheat Cleaning Apparatus with Centrifugal Fan-Oscillating Sieve (single air channel centrifugal blower+double-deck screen shale shaker) mostly, single air channel centrifugal blower is for generation of cleaning air-flow, utilize the difference of each component in emersion object (comprising seed, short stem, clever shell and a small amount of light assorted remaining etc.) floatation characteristic, coordinate double-deck vibration wire gauze sieve or lip(ped) sieve, jointly complete seed and stem stalk, assorted more than etc. separating cleaning.Research shows, tradition Type Airflow Rice-Wheat Cleaning Apparatus with Centrifugal Fan-Oscillating Sieve has become the main bottleneck of the large feed quantity rice combine development of restriction at present, it is embodied in: high-yield super rice moisture content is high, and each component floating velocity of emersion object is staggered, an air flow cleaning blows holder layering difficulty; When high-yield super rice emersion object is cleaned, feed quantity is large, and seed is difficult to fast sieve thoroughly, seriously constrains transaction capabilities and the efficiency of cleaning plant, and traditional cleaning plant can not adapt to the requirement that crop varieties is constantly updated, per unit area yield improves rapidly.
Internationally famous John Deere, CASE, New Holland, the 988 STS(John Deere that the American-European agricultural machinery trans-corporation such as CLAAS researches and develops in recent years), 2388(CASE), CR980(New Holland) and TUCANO 470(CLAAS) etc. large-scale combined harvester product, there is feed quantity large, operating efficiency is high, intelligence degree high, but these types are mainly used in gathering in the crops wheat, soybean, the Dry crops such as rape, general employing wheel undercarriage, swath 6 ~ 10 meters, conduct oneself with dignity 8 ~ 10 tons, China's paddy rice characteristic cannot be adapted to, the 10-15 mu field size of super hybridization rice main producing region, south and deep mud corner operating environment.In addition, its cleaning plant adopts the combining structure such as two fans (or major diameter two air channels blower fan), precleaning shuttle board, backhaul delivery board, multilayer sorting screen, and physical dimension is huge, cannot be applied on China's rice combine.Half feeding combined harvester of the states such as Japan and Korea S limits by self structure, cannot realize maximizing, and operating efficiency and results adaptability cannot significantly improve, and progressively exit the mainstream market of China's rice harvesting machine.The more important thing is, although the developed country such as American-European produces large-scale combine product, belong to the vital strategic secrets of each company about the test data of its high-performance cleaning plant, design theory and method, can not external disclosure.In a word, theory and means also not relevant abroad can be used to the design instructing China's large feed quantity rice combine cleaning plant, simultaneously because the difference of manipulating object self character, makes us also cannot use the design experiences of external product.
In addition, because combined harvester manipulating object significant difference, working condition are ever-changing, operating environment complex all causes remarkable impact to the performance of cleaning plant, tradition cleaning plant part-structure and kinematic parameter can only by manual mode, empirically carry out having level to regulate, cannot according to the change of manipulating object and environment, the job state parameter of automatic adjustment cleaning plant ensures transaction capabilities, and its results adaptability is poor.Under the condition ensureing sorting performance, it is the inexorable trend of cleaning technical development that running parameter can carry out self-adaptative adjustment according to operating condition.Make a general survey of external advanced combined harvester, electronic information technology obtains extensive utilization thereon, combining function adjusts various running parameter automatically according to the operation quality in operation process, while enhancing productivity, fault rate is controlled within the specific limits, substantially increases the time between failures of complete machine simultaneously.Compared with the combined harvester of American-European trans-corporation advanced person, China's combine harvester is mostly only provided with blocking, tanker a small amount of warning device such as completely, generally shortage running parameter and transaction capabilities are monitored, electronic/automatic adjustment of running parameter waits Intellectualized monitoring device, make machinery operation unstable properties, operating efficiency relies on the qualification of tractor driver, and it is large to handle intensity, plugging fault takes place frequently, its time between failures abroad type 1/5th, cannot adapt to meet China's paddy rice large-scale production and rice oil (wheat) crop rotation district and the job requirements such as rush-harvest and rush-plant.In recent years, Chinese scholars has carried out a large amount of research work in combined harvester intellectualized technology, but great majority research is only for single running parameter and the monitoring of transaction capabilities parameter or the research of forecast model, the current work parameter value not have basis to monitor carries out FEEDBACK CONTROL and also relatively less to the research of many job parameters fused controlling to associated components.
