弹齿滚筒式辣椒采摘装置性能的试验研 究 .KA] 雷明举 王飞 王梦 薛风 贺艳 陈永成 新疆工程学院机械工程系石河子大学机械电气工程 学院 针对弹齿滚筒式辣椒采摘装置采净率低、破损率高、损失率严重的问题，设计试 验台并进行采摘装置性能的试验研究。以运行速度、齿间距离、滚筒转速作为试 验影响因素，以采净率、破损率、损失率为指标，对试验结果进行极差分析和方 差分析。结果表明当运行速度为3m/s、齿间距离为45mm、滚筒转速为150r/min 时，采摘装置采净率可高达95. 29%,破损率降低为2. 89%,损失率减少到 6.47%。同时，针对采净率建立回归方程，为采摘机理研究和分析提供了必要的 参数依据。 关键词 弹齿滚筒式;采摘装置;性能试验;因素分析; 雷明举（1984-），男，湖北十堰人，工程师，讲师，（ ） leimingju0852@126. com。 王飞（1981-）,男，湖北孝感人，讲师，（E-ma 11） 233045660@qq. com。 2017-03-02 基金国家自然科学基金项目 Experimentai Study on Performance of Chili Picking Device Based on Spring Tooth Roller一type Lei Mingju Wang Fei Wang Meng Xue Feng He Yan Chen Yongcheng Department of Mechanical, Xinjiang Engineering College; Mechanical and Electricol Engineering College, Shihezi University; Abstract In view of the spring-tooth roller type chili picking device picking degree is low, breakage rate is high and the serious loss rate, which takes tooth spacing, feeding speed and rotational speed of cyl inder as influncncc factors, dcsign test bench and take orthogonal test of the performance of the picking device. Extreme variance analysis of the test result uaing data processing software is to determine the effect of picking performanee index factor of excellent level, order and optimization combined. The test results indicates that the when the feed ing speed is 3m/s, the tooth spaci ng is45 mm, the rotationed speed of cylinder is 150r/min, the picking degree rate can up to 95. 29%, the breakage rate is reduced to 0. 89%, the loss rate is reduced to 6. 6%. In view of picking rate, establish regression equation, which can provide the necessary parameters for the research and the analysis of picking mechanism.
