考虑完全拆除旋耕机耕整组件后手扶拖拉机的动力可用性、纸盆尺寸和空间可用性，开发了一种9.75kW手扶式手扶拖拉机驱动的2行全自动单盆育苗蔬菜移栽机。它由两套喂料输送机、计量输送机、落苗管、开沟器、覆土装置、自动喂料机构、深度调节轮和挂接装置组成。喂料输送机采用水平板条式链式输送机，计量输送机采用水平推板式链式输送机。自动喂料机构由同步轴、凸轮和离合器组成，用于协调喂料和计量输送机的工作。蔬菜插秧机在两条喂料输送机上垂直输送 108 株秧苗，将它们喂入计量输送机，然后将它们垂直种植在犁沟中。蔬菜移栽机的性能评估是在田间以 45 x 45 cm 间距以 0.9 km h(-1) 的前进速度移栽番茄。移植机的田间容量为 0.026 ha h(-1)。与传统的手工移栽方法相比，节省了68%的劳动力和80%的时间。插秧机的栽植率为32盆苗min(-1)，其中漏栽率4%，斜栽率5%。所研制的蔬菜移栽机覆土效率约为81%，移栽质量令人满意。 (C) 2011 年 IAgrE。由爱思唯尔有限公司出版。保留所有权利。
A 9.75 kW walk-behind type hand tractor powered 2-row fully automatic vegetable transplanter for individual paper pot seedlings was developed by considering the power availability, paper pot dimensions and space availability in the hand tractor after the complete removal of rotavator tillage assembly. It consisted of two sets of feeding conveyor, metering conveyor, seedling drop tube, furrow opener, soil covering device, an automatic feeding mechanism, a depth adjustment wheel and hitching arrangement. Horizontal slat-type chain conveyor was used as feeding conveyor and horizontal pusher type chain conveyor was used as metering conveyor. The automatic feeding mechanism, with a timing shaft, cam and clutch, was used to coordinate the working of feeding and metering conveyors. The vegetable transplanter carried 108 seedlings on two feeding conveyors in upright orientation, fed them to the metering conveyors and planted them in upright orientation in furrows. The performance of the vegetable transplanter was evaluated for transplanting tomato at 45 x 45 cm spacing in the field at a forward speed of 0.9 km h(-1). Field capacity of the transplanter was found to be 0.026 ha h(-1). It resulted in the saving of 68% labour and 80% time over the conventional method of manual transplanting. The planting rate of the transplanter was found to be 32 pot seedlings min(-1) with 4% missed planting and 5% tilted planting. The soil covering efficiency of the developed vegetable transplanter was about 81% and the quality of transplanting was satisfactory. (C) 2011 IAgrE. Published by Elsevier Ltd. All rights reserved.
