Bananas are an important cash crop,has been widely cultivated in subtropical regions,which played an important role in regional economic development.With the banana-planting area increased,waste banana pseudostem has become a bottleneck restricting the development of banana industry.Banana crushing technique provides a good solution for this problem.Banana crushing technique can improve soil properties,improve the next crop root system vitality,avoid the ecological damage from abandoned pseudostem,and reduce carbon emissions,increasing crop yields.Because of the crushing research started late in banana pseudostem stout and South subtropical area,there are few banana combination machine.The current banana pseudostem needs machines with lower efficiency.To solve these problems,combining the characters of banana pseudostem and grinding mechanism,improved the 1XHJ-1600 horizontal banana pseudostem grinding machine.Banana crushing knife roll?stubble knife roll?repression device are the key components of crushing machine.Optimized content are as follows:(1)Banana crushing knife roll arranged in a spiral,and each holder holds a left bend L-shaped knives and a right bend L-shaped knives with the tip facing outwards.The crushing effect of machine is good,and did not exist obvious winding.(2)Run the plug-in Simulation of Solidworks 2013 for the first four modes of crushing knife roll to avoid resonance damage analysis.(3)Four stubble-knife cutter evenly distributed in cutterhead,in which two types of stubble-knife cutter installed alternately.Banana stubble crushing knife roll arranged in a herringbone,can crush the effective fulfilment of the banana root system,force and torque on the blade will also achieve the basic balance.(4)The original crackdown-roller improvements to spring roller adjusting polygon repression.Compression spring on the spring rod through the stop pins adjust length to accommodate different soil depth and the town pressures.Both ends of the connection shaft through rear lug bolt is available in shell,suppressed roller around its rotating to different heights.Rollers on each side of the polygon embedded in a pair of ribs,fuselage relatively parallel with the ground.Spring adjusting device of floating design can be flexibly adjusted the root depth of the blade on the one hand,also can be placed daily when the mast to avoid root and stubble damage cutter.The device has a simple structure,height-adjustable for different soil moisture can be relatively satisfied with the compaction effect of the Earth's surface.Through the field tests in banana plantations of ChengMai County,the banana smash pass rate,stubble crushing rates were measured,were better than the national standard requirement,meet the relevant national standards and agricultural requirements.In addition to tractor travel speed,banana crushing knife roll speed and root out ran speed cutter designed three factors and three levels for the variables orthogonal affecting banana crush rate and stubble crushing rates of significant order,and the optimal combination.Improved 1XHJ-1600 horizontal banana crushing returning multi-functional machine for joint operations,one banana and crush the stubble field operations,reduced in number,reduced operation power.Improved structure and parameters is more reasonable,high machine stability while you work,you can continue to field operations,improve work efficiency,saving energy,susceptible to promote production.
