Description
Technical field
The present invention relates to a kind of united reaper field performance test system and test method, belong to rice field harvesting facility field.
Background technology
Along with developing rapidly of agricultural equipment, the application scale of united reaper, results performance and automaticity oneself become the important measurement index of modern agriculture.At present, existing united reaper, the most perfect, when harvester operates in actual field, cleans quality relatively low.Causing the main cause of this problem is that the structure design of threshing system of united reaper is the most perfect, and cut flow roller, double longitudinal axial flow roller, vibrosieve crank axle and blower fan use same power drive, speed regulating control cannot be distinguished, and use empirical parameter to carry out speed setting, thus cleaning efficiency is the highest, percentage of impurity and seed breakage rate are higher.
Patent CN1634424415A, disclosure has invented a kind of united reaper grain cleaning device, it is to add rubber surface in vibrosieve in rule make damping action with rushing down, reduce the loss that grain spring causes, but rubber surface can affect the vibration impurity removing rate of vibrosieve equally, the non-threshing performance of corn is made to improve.Patent CN163641501515A, disclosure has been invented a kind of threshing cleaning unit for longitudinal axial flow united reaper, has been to add a low early and high after transition apparatus between notch board grid and vibrosieve, effectively prevent the loss that the grain drift of notch board grid rear portion causes.And corn is once cleaned, it is effectively improved cleaning efficiency and clean rate, but transition apparatus exit easily causes corn and piles up in vibrosieve relevant position, affects its service behaviour.
Patent C16215192424A, the realtime on-line monitoring method of the open cleaning loss having invented a kind of grain combine and device thereof, patent CN19196632415U, disclosure has invented cleaning loss detection device of grain combine harvester.Patent C16215192424A and patent CN19196632415U, in terms of the monitoring that grain cleaning loses, are proposed a kind of reliable way, but only monitoring cannot improve the rate of cleaning, the running parameter that also cannot improve equipment.Patent 1619150195A, discloses and has invented a kind of multi-parameter control system for threshing performance of combined harvester, and this system can realize the Based Intelligent Control to cut flow roller, it is ensured that its service behaviour, thus improves cleaning efficiency.Although this patent achieves the Based Intelligent Control to cut flow roller, but control the most unilateral, do not include same to far-reaching pair of longitudinal axial flow roller of the rate of cleaning, vibrosieve and the control of blower fan, make control effect excessively localization, it is impossible to reach the overall effect controlling and matching.
In sum, in prior art, in united reaper threshing system, the controllability degree of all parts is relatively low, main also in terms of study on monitoring, in the actual field running stage, in threshing system, cut flow roller is the most uncontrollable with the rotating speed of blower fan with the rotating speed of double longitudinal axial flow rollers and moment of torsion, vibrosieve crank axle.And the united reaper actual field running stage, need to be controlled stablizing its service behaviour to cut flow roller, double longitudinal axial flow roller, vibrosieve crank axle in each parts especially threshing system with blower fan, thus reduce cleaning loss and non-threshing performance.
