Abstract

At present, farmers who own a sugarcane harvester are becoming more interested in purchasing a sugarcane billet planter. However, the planting consistency of this type of planter is still low. Thus, its metering device should be improved. The objective of this study is to develop the shape and arrangement of the metering device of the billet planter and study its effect to the discharge consistency. The original billet metering device consists of a rubber conveyor belt with flat steel cleats that have a length equal to the conveyor width, while the developed metering device uses 20-degree inclined-edge cleats. The cleats were shortened to ⅔ of the conveyor width and aligned in left-right alternation. The developed metering device was evaluated compared with the original device, considering the precision of billet discharging during the stationary tests. The linear speed of the conveyor was controlled at 0.189 m/s. The test results showed that developed metering devices gave a precision index of 50.67%, which is 9.66% higher compared with that of the original. The developed metering device had higher torque than the first metering device and higher fluctuation.

计量装置布置对甘蔗方坯机排料一致性的影响

目前，拥有甘蔗收割机的农民对购买甘蔗坯料播种机越来越感兴趣。但该类型播种机的种植一致性仍然较低。因此，需要对其计量装置进行改进。本研究的目的是开发方坯机计量装置的形状和布置，并研究其对出料一致性的影响。原钢坯计量装置由橡胶输送带与长度等于输送机宽度的扁钢夹板组成，而研制的计量装置采用20度斜边夹板。夹板缩短至输送机宽度的三分之二，并以左右交替方式对齐。考虑到钢坯在固定试验过程中的放电精度，对所研制的计量装置与原装置进行了比较评价。输送机线速度控制在0.189 m/s。试验结果表明，研制的计量装置的精密度指标为50.67%，比原装置提高了9.66%。所研制的计量装置比第一种计量装置具有更高的扭矩和更高的波动。
