If crops with considerable spacing can be arranged in a precise rectangular pattern, mechanical weeding can become an alternative to chemical methods by enabling treatment in two perpendicular directions. Realisation of such a pattern requires innovation of seedling transplanters. A computer vision-based sensing system was developed for detecting a transplanters posture relative to the crop. A ...

Automatic transplanters have been very important in greenhouses since the popularization of seedling nurseries. End-effector development is a key technology for transplanting plug seedlings. Most existing end-effectors have problems with holding root plugs or releasing plugs. An efficient end-effector driven by a linear pneumatic cylinder was designed in this study, which could hold root plugs ...

Aiming at the problems of high specificity and low efficiency vegetable transplanting machine, a substrate block seedling transplanter was designed. Through theoretical calculation force analysis, structural parameters two key components automatic separation device planting are determined. Taking cabbage seedlings with 40 × 40mm size as experimental object, effects forward speed, frequency, fro...

To improve the seedling-picking efficiency of vegetable transplanter and reduce damage rate seedling pot, a reciprocating device driven by full air pressure was designed. In this paper, structure working principle pneumatic are introduced. Through mechanical analysis between claw parameters such as stroke driving force clamping cylinder were determined. According to action sequence mechanism, w...
