Abstract

The objective of this study was to develop a generator-powered self-propelled automatic tray loading/unloading machine for rice seedling nurseries by using a gantry as the transport system to automate seedling tray placement and harvesting. During input operations, seedling trays are transported by conveyor belts to the nursery, and the tray loading/unloading machine automatically places the trays in rows in the nursery. During output operations, the tray loading/unloading machine automatically gathers the seedling trays from the nursery and transports them on conveyor belts to an automatic seedling mat roller. The entire system comprises mechanical components that achieve high operational stability and few malfunctions. Using a programmable logic controller for automation can effectively alleviate the inconvenience of laying heavy power cables. The tray loading/unloading machine automatically moves along the trusses of the gantry transport system, placing seedling trays in rows in the nursery. Alternatively, it can reverse directions and gather seedling trays from the nursery and transport them to the conveyor belts. The tray unloading capacity is 741 trays per hour, and tray loading capacity is 763 trays per hour. The tray loading/unloading machine enhances the automation operation of rice seedling nursery and alleviates the difficulty in hiring workers in farming villages where there are a shortage of labor.

用于水稻苗圃的发电机驱动的自走式自动托盘装卸机的研制

本研究的目的是开发一种发电机驱动的自行式水稻苗圃自动托盘装卸机，采用龙门作为运输系统，实现苗圃托盘的自动放置和收获。输入作业时，育苗托盘由传送带输送至苗圃，托盘上下料机自动将托盘成排放置在苗圃内。在输出作业时，托盘上下料机自动将苗圃上的苗盘收集起来，通过传送带输送到自动苗席滚筒上。整个系统由机械部件组成，运行稳定性高，故障少。采用可编程逻辑控制器实现自动化，可以有效减轻重型电力电缆敷设带来的不便。托盘装卸机自动沿龙门架运输系统的桁架移动，在苗圃内成排放置苗木托盘。或者，它可以反转方向，从苗圃收集苗盘，并将其运送到传送带上。托盘卸载能力为741盘/小时，托盘装载能力为763盘/小时。托盘上下料机提高了水稻苗圃的自动化操作，缓解了农村用工难的问题。
