Solid design and experiment of forage harvester. The authors declare no conflict of interest. Establishment of Optimization Mathematical Model 2.1. This study can provide parameter foundation and optimization method for lowering chopping power consumption of the chopper. The choppers before and after the optimization of structural parameters were sequentially mounted on the performance test bench of the chopping system of the forage ramie harvester to further verify the accuracy of the optimization results. The mathematical model is solved and evaluated by MATLAB software, and then the structural parameters and optimization results when the chopper reaches the theoretical minimum chopping power the consumption results are obtained. On the premise of ensuring the chopping effect of the chopper, the structural parameters of the chopper are optimized with the purpose of minimizing the chopping power consumption when the chopper works, and the mathematical model of optimal design of chopper is established. Therefore, this paper uses the flat hob chopper (referred to herein as chopper) in the chopping system of the forage ramie harvester developed by one research group as their research object. To summarize, the majority of research on chopperвЂ™s power consumption has focused on the blade shape, blade curve, and operation parameters of the chopper, with few investigations examining the effect of chopperвЂ™s structural parameters on chopperвЂ™s power consumption. and others explored the relationship between blade shape and chopper speed on chopping power consumption. The sliding chopping angle is different when the same blade is installed in different forms. and others considered the sliding chopping angle when exploring the power consumption of the chopper, they did not study the problem in depth. and others also explored the influence of straw moisture content on chopping power consumption. In addition to considering the operation parameters of chopper, Fang, M. and others used multifactor experiments to explore the relationship between the operation parameters of chopper and chopping power consumption to reduce the chopperвЂ™s chopping power consumption. Jia Honglei and others applied the principle of dynamics to design a cylindrical blade with a curve surface and a straight edge line and studied the functional relationship between rotation speed of the chopper and chopping power consumption by using the regression analysis method. and others designed a bionic blade using bionics principles to reduce chopping power consumption. Li Bing and others found that sliding chopping can reduce chopping power consumption by studying the relationship between blade curves and chopping power consumption of the chopper. The chopperвЂ™s power consumption has been extensively studied. This study can provide parameter foundation and an optimization method for lowering chopping power consumption of the chopper.

The chopping power of the chopper is reduced by 22.25% after optimization, which is close to the software analysis value (25.50%), indicating that the optimization result is accurate and reliable. The test results show the standard-length rate of ramie stalk chopped by the choppers before and after the optimization of structural parameters were 92.96% and 92.84%, respectively, which were extremely close to each other, indicating that the optimization of structural parameters has no influence on the chopping effect of the chopper.

Surface awaken before and after trial#

The choppers before and after the optimization of structural parameters was trial manufactured and sequentially mounted on the performance test bench of the chopping system of the forage ramie harvester. The analysis result of chopping power curve is the chopping power after structural parameter optimization is reduced by about 25.50% compared with that before optimization. When the radius of the chopper is 0.11 m, the chopper can obtain the theoretical minimum chopping power. The results indicate that when the coordinate value of point A on the blade edge line on the Z axis is 0.7 m the included angle between the bottom surface of the blade and the axis of the cutter roll is 6В°.

The chopping power curves of each point on the chopper blade edge line before and after the optimization of structural parameters are generated. With the help of MATLAB software, the mathematical model is solved. In order to reduce the chopping power consumption of a flat hob chopper (referred to herein as chopper) on the premise of ensuring the chopping effect of the chopper, the mathematical model of optimal design of chopper is established in this paper with the minimum chopping power as the objective.
