刮刷式加工番茄采摘装置试验研究

Experimental Research of Scraping and Picking in Batches Device on Processing Tomato

为实现加工番茄的分批次采摘,确保已成熟番茄果实的及时收获,设计了一种刮刷式加工番茄分批次采摘装置,选择加工番茄屯河8号进行果实采摘性能的单因素试验。用SAS软件对试验数据进行统计分析,结果表明:随着采摘板转速增大,果柄分离率先升高后降低,青果率和果实破损率则是逐渐增大;随着装置行进速度增大,果柄分离率逐渐降低,青果率和破损率则是逐渐增大;当采摘板转速为24r·min^(-1),装置行进速度为2.20km·h^(-1)时,采摘效果最好。该装置的设计为研制新型刮刷式加工番茄分批次收获机械提供参考。

In order to realize the harvest of processing tomato by picking in batches and insure harvest of the ripe tomatoes in time , design a kind of processing tomato wiper batches picking device and select processing tomato Tunhe 8 sample material for fruit picking performance by the single factor experiment. Test results were statistically analyzed by SAS software. The analysis report show that： with the picking plate speed increasing, fruit stalk separation rate increasing first and then decreasing, greening rate and fruit damage rate are always increasing; with the device walking speed increasing, fruit stalk separation rate decreasing gradually,greening rate and fruit damage rate are always increasing; when picking plate speed is 24r·min^-1 and device walking speed is 2.20km ·h^-1, harvest indicators achieve to the best. The device is designed to provide a reference for the development of a new batch of tomato harvesting.
