| 目的 针对市场上现有的长生果去壳设备在粒度相差较大时，壳和仁分离不完全、剥净率低等问题，对其进行创新性改进设计。方法 基于TRIZ理论，对市场上应用最广泛的长生果去壳机的工作原理进行分析，对其存在的问题进行分析，利用发明问题解决理论，通过宏观的矛盾矩阵法，得到相对应的创新设计原理。结果 根据选取的最优原理，解决了设计过程中出现的4个主要技术冲突。利用参数变化原理，将Ⅰ级去壳装置中起碾压作用的工作板改成连续变化的斜面，解决了脱壳效率低的问题；利用分割原理和动态特性原理，将驱动曲柄设计成长度可调的形式，使生产节拍可调，实现了柔性生产；利用有效运动的连续性原理，通过增加专门用于小果、秕果的碾压装置，提高了剥净率及设备的自动化程度；利用多用性原理，用Ⅲ级去壳装置的动力源代替果壳收集装置的动力源，使设备结构更加紧凑。结论 实验结果表明，新型长生果柔性去壳机可实现大白沙剥净率达到97.6%，四粒红剥净率达到98.2%，均高于现有去壳设备；大白沙破损率为1.97%，四粒红破损率为1.18%，均低于现有去壳设备。设计结果对类似去壳设备的设计研究奠定了一定的理论基础。 |

| The work aims to innovatively improve the design of the existing longevity fruit shelling equipment in the market because of large particle size difference, incomplete husk and kernel separation and low peeling rate. Based on TRIZ theory, the working principle of the existing shelling machine for longevity fruit in the market and the corresponding problems were analyzed. The theory of solving inventive problems and macro contradiction matrix method were adopted to obtain the corresponding innovative design principle. According to the selected optimum principle, four main technical conflicts in the design process were solved. Based on the principle of parameter variation, the working plate in the first stage shell removal device was changed into a continuous inclined plane, which solved the problem of low efficiency of shell removal. Based on the principle of partition and dynamic characteristics, the driving crank was designed to be the type with adjustable length, so that the production rhythm could be adjusted and the flexible production could be realized. Based on the continuity principle of effective movement, the peeling rate and the automation degree of the equipment were improved by adding a rolling device specially used for small fruits and blighted fruits. Through the principle of multiplicity, the power source of the three-stage shelling device was used to replace the power source of the shell collecting device to make the structure more compact. Experiments show that the new flexible shelling machine can achieve 97.6% of the peeling rate of Dabaisha and 98.2% of the peeling rate of Four-grain Red, which are higher than that of the existing shelling equipment. The breakage rate of Dabaisha and Four-grain Red is just 1.97% and 1.18%, which is lower than that of the existing shelling equipment. The design results lay a theoretical foundation for the design and research of similar shelling equipment. |
