Abstract/ Executive Summary:

Current vegetable seedling transplanting method is manual that means need to make a hole in the soil then put the seedling at the proper depth and finally fill-up the hole. All of these works are laborious, time-consuming and costly. Three-dimensional projection of the transplanter was drowned by Solidworks-2016. A power tiller operated vegetable seedling transplanter was designed and fabricated with locally available iron materials at Farm Machinery and Postharvest Process Engineering Division of Bangladesh Agricultural Research Institute, Gazipur during 2018-19. The transplanter consisted of dibbler, dibbler pressing sprocket, chain, press wheel, seat, depth adjusting wheel, etc. The machine can transplant seedling two rows at a time and distance between the rows is adjustable up to 40-100 cm. Seedling spacing was adjusted and irrigation water was supplied at a time. The experiment will be continued in the next year for better field performance.

Keywords: Vegetable seedling transplanter, Fabricated, Power tiller operated

Start Date: 00-00-2018

End Date: 00-00-2019

Program Area: Farm Mechanization

Commodity: Transplanter

Objectives:

To design and develop a power tiller operated vegetable seedling transplanter
To test and performance evaluation of the vegetable transplanter

Methodology:

A power tiller operated vegetable seedling transplanter was designed and fabricated at Farm Machinery and Postharvest Process Engineering Division of Bangladesh Agricultural Research Institute during 2018-19. Three-dimensional projection of the transplanter was drowned by Solidworks 2018. Then fabrication was done according to design and locally available materials were used to fabricate the machine. The schematic views of the transplanter are shown. Working principle: The transplanter is attached with a power tiller. When power tiller moves forward, chain and sprocket of transplanter should be moved the same direction because it was connected with a wheel shaft of power tiller. This chain and sprocket used to transfer the power from power tiller, and at the same time increase speed 1.81 times, then the forward speed of power tiller wheel and sprocket would be the same. The diameter of the sprocket is 34.5cm to press the dibbler and make a hole in the soil. Two labor are needed (two rows seedling at a time) to put the seedling at the proper depth in the hole. After placing the seedling, press wheel will press to cover the hole with soil. The main parts with construction materials and major components of vegetable seedling transplanter were shown.

Achievement/Findings:

A power tiller operated vegetable seedling transplanter has been designed and developed for the farmer to reduce the labor, cost, and drudgery in seedling transplanting. Due to time constraints, this year this machine could not be tested in the field. Thus the experiment will continue for the next year.
