Embodiment
In order to illustrate the technical solution of the utility model and technical purpose, below in conjunction with drawings and the specific embodiments, the utility model is described further.
The top of cleaning chamber of combined harvester internal vibration sieve 9 is provided with front threshing cylinder 1 and rear threshing roller 7, and the below of vibratory sieve 9 is provided with conveying mechanism, and described conveying mechanism comprises defeated grain auger 6 etc., and described blower fan 2 is positioned at the side of vibratory sieve lower conveyor structure.The top of cleaning room is formed, below vibratory sieve 9 and blower fan 2, form the bottom of cleaning room between frame 3 between threshing cylinder and vibratory sieve 9.
The utility model cleaning chamber of combined harvester Wind field measurement device, comprises sensor, mounting frame for sensor and wind guiding mechanism etc.
Described mounting bracket comprises the many support link 11 be horizontally installed in cleaning room, the body of rod of every root support link 11 is provided with some clamp button of the spring 10, for fixation of sensor probe 13, and every root support link 11 is furnished with at least one sensor probe 13, described sensor probe 13 is connected with control system by cable 14.During installation, the two ends of support link 11 are fixed on the sidewall of cleaning room, be parallel to each other between each support link 11, align before and after the clamp button of the spring 10 of the corresponding precedence in different support link 11, the clamp button of the spring 10 that each support link 11 is arranged constitutes a buckle array.
For the ease of collection and the analysis of Wind parameters in wind, the support link 11 of transverse direction is set as the air-out direction perpendicular to cleaning room blower fan 2 air outlet.Described sensor can be in air velocity transducer, wind transducer or air flow sensor one or more, be used separately as the isoparametric collection of wind speed field, wind direction and air quantity.
The adjustable wind deflector of guiding is provided with in the position near blower fan 2 air outlet, described wind deflector comprises wind deflector 4 and lower wind deflector 9, forms air channel, three, upper, middle and lower respectively between the upper edge of fan outlet and upper wind deflector 4, between upper wind deflector 4 and lower wind deflector 9, under fan outlet between edge and lower wind deflector 9.
Described mounting bracket comprises and is arranged in some support link 11 being in same level height above vibratory sieve 9, is positioned at some support link 11 above vibratory sieve 9 lower conveyor structure, is positioned at least one support link 11 in upper air duct exit and is positioned at least one support link 11 at ducting outlet place.And in lower air duct, whether support link is installed and sensor need be selected according to actual conditions.Because lower wind deflector 9 is comparatively near defeated grain auger 6, gather at present below wind deflector 9 warehouse can pile with cereal, generally sensor is not set in lower air duct.
Be measured as example with wind speed field, above-mentioned cleaning chamber of combined harvester wind field (wind speed field) measuring method, comprises the following steps:
(1) in cleaning room wind field, selected eight the parameter acquisition points 8 of air-out direction in face of blower fan 2, comprise the collection point of the three place's sustained heights be arranged in above vibratory sieve 9, are positioned at the collection point, place that upper air duct air outlet goes out, the collection point, place being positioned at ducting outlet place, are positioned at the collection point of three differing heights positions, place above defeated grain auger 6.Then each support link 11 is arranged according to each collection point horizontal direction at place in wind field, a clamp button of the spring 10 is provided with at the two ends of every root support link 11 and centre, make to align before and after the clamp button of the spring of corresponding precedence in each support link 11, form three row buckle files;
(2) clamp button of the spring 10 being positioned at the first file in each support link installs sensor probe No. 1 to No. 8, as shown in Figure 1;
(3), after adjusting the direction of each sensor probe 13 air inlet 12, detect, complete the parameter acquisition of a wind field vertical section;
