Abstract

Aiming at the problems of high specificity and low efficiency of vegetable transplanting machine, a substrate block seedling transplanter was designed. Through theoretical calculation and force analysis, the structural parameters of two key components of automatic seedling separation device and planting device are determined. Taking cabbage seedlings with 40 × 40 × 40mm substrate block size as the experimental object, the effects of forward speed, planting frequency, front conveyor belt speed on lodging rate, missing rate and qualified rate were studied by single factor test and three factor three-level orthogonal test. Based on the analysis of the significance and interaction of the experimental data, the best combination of the forward speed of 1.1km/h, the planting frequency of 55 plants / min and the front conveyor belt speed of 0.5km/h was obtained. The verification test of the best combination showed that the average qualified rate of planting was 93.31%, which met the relevant industry standards.

针对现有蔬菜移栽机专用性强，低效费工等问题，设计了一种基质块苗移栽机。通过理论计算、受力分析确定了自动分苗装置和栽植装置两大关键部件的结构参数。以基质块尺寸为40×40×40mm的甘蓝苗为试验对象，通过单因素试验和三因素三水平正交试验，研究了前进速度、栽植频率、前输送带速度等因素对倒伏率、漏栽率和合格率的影响，并进行了显著性和交互作用影响分析，获得了前进速度为1.1km/h、栽植频率为55株/min、前输送带速度为0.5km/h的最佳参数组合，对最佳组合进行了验证试验表明，平均栽植合格率为93.31%，满足相关行业标准。
