Design And Experimental Of Harvesting-balling Mechanism Of Rice Stubble

In this paper,to face practical problem and requirements of dealing with rice stubble, To solve the pollution caused by burning and the heavy metal pollution,We proposed to the concept that collect rice stubble then professional treatment.Via reading a review of relevant literature.introduced the current domestic and international monomer balers and co-operating machine,analyzed their strengths and weaknesses,it not only can pick up and bale harvest,but also can be commonly used for rice combine walking with chassis and power.And can continuity play a round bale job requirements,designed a Harvesting-balling Mechanism of Rice Stubble.Used Simulation to analysis the working parts of aggregate-feed box. Finally.to field trial of the Harvesting-balling Mechanism of Rice Stubble.Conclusions are as follows:1. Experiment measured physical parameters of rice stubble, obtained "stand stalk" and "stubble" the proportion of 7:3,the average moisture content of rice stubble was 39.71%;the length distribution of"stand stalk"is in31.6 to 37.2cm,the length distribution of "stubble" is in 38.7 to 45.3cm; the amount of rice stubble per square meter of 2.03kg/m2.It provided technical parametersthe for designing and researching of Harvesting-balling Mechanism of Rice Stubble.2. To achieve the continuity of Harvesting-balling Mechanism of Rice Stubble,the innovative design is the aggregate-feed box,the aggregate-feed box Grilled tooth telescopic conveyor speed is 1.57m/s,balers picker’s picking up speed is 2.51m/s,the feeding amount of 3.36kg/s, its aggregate volume of the feed box to accommodate at least the amount of 33.6kg of rice stubble.3. Using SolidWorks Simulation to analysis working parts of aggregate-feed box, optimization of the aggregate-feed box frame,aggregate-feed box,telescopic Grilled teeth and comb brush pressure size of the rod. and verify the mechanical properties of the main components of aggregate-feed box to meet operational requirements.4. The field experiment of Harvesting-balling Mechanism of Rice Stubble showed that:the continuity of play in the realization of round bales job, its cutting table auger conveying speed is 3.14m/s,the cutting table feed amount of 3.36kg/s,;trough conveying speed is 3.41m/s,trough feeding amount of 6.22kg/s;baler pickup pick up speed is 2.51m/s,baler pickup feeding amount of 8.42kg/s;the set Grilled tooth material feed box telescopic shaft speed is at 90r/min～110r/min within the range (retractable tooth feed linear velocity speed is at 1.41m/s～1.73m/s). the amount of feed fed to the teeth stretching is 7kg/s.
