Seedling Transplanter

Design and force analysis of end-effector for plug seedling transplanter

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 ...

Wangyuan ZONG -6.27-Design and Simulation of Jujube Sapling Transplanter

This paper is aiming at designing a novel jujube transplanter with mechanic arms, which can support the sapling for a while when other operations is going on. It improves uniformity and stability. Pro-E software has been used for the design process, by which transplanting process has been analyzed and simulated.

Design and Simulation for Bionic Mechanical Arm in Jujube Transplanter

In this paper an automatic bionic mechanical arm of jujube transplanter has been designed and simulated with Pro/E and ADAMS software. The device can achieve the work of clamping—sending—setting the sapling and support the sapling to guarantee it perpendicularity in setting process. Design the structure of manipulator utilizing the simulation of hand working. There is 5-DOF at the manipulator t...

Seed mass, seedling size and neotropical tree seedling establishment

1 We examined amongand within-species effects of seed mass for seedling establishment from seed to 5 years of age in a field experiment at Paracou, French Guiana. 2 Six seeds of each of eight species were weighed and planted into each of 120 plots (1 m 2 ) throughout closed-canopy forest along 12 100-m transects in 1998. 3 We described the microhabitat of each planting site using principal comp...
