Study Notes
Design Considerations
- Proper selection of blade shape and geometry for optimal performance.
- Choosing suitable blade material to ensure durability and effectiveness.
- Proper rack angle and throat clearance calculations for efficient operation.
- Draft force calculations tailored to the specific soil type being worked on.
- Ability to adjust depth for variable draft requirements during operation.
- Determine optimum machine travel speed to maximize power and system efficiency.
Sapling Handling
- Saplings must be dropped into pre-dug holes by the machine without causing damage.
- Machines need to efficiently cover the soil to support healthy rooting and prevent visibility of roots.
- Ensure that saplings remain stable and protected from wind disturbance.
Auxiliary Items
- Mandatory four sapling trays required for carrying and organizing saplings on the machine.
- Teams should carry at least 20% extra saplings to account for potential losses during evaluations.
- Sapling trays will be supplied by the TIFAN team.
General Design Requirements
- Machine configuration as a tractor-pulled attachment with no operator seating allowed.
- Attachments should use PTO (Power Take Off) for powered functions.
- The machine must have a minimum of three tie-down points for safe lifting, with a diameter of at least 50.8 mm.
Automated Multi Vegetable Transplanter Machine Dimensions
- Track width should range between 1300 mm to 1600 mm.
- Overall length must be less than 2500 mm, and attachment width should not exceed 1800 mm.
- Overall height limit set to under 2000 mm, with kerb weight under 400 kgs.
- Tractor operating speed should be maintained between 1.5 to 2 km/h, with PTO rpm at 540.
Field Layout
- The equipment to operate in a straight 25-meter path, subject to adjustment based on field conditions.
- Specific row-to-row and plant-to-plant distances provided for different crops.
- Teams should demonstrate equipment versatility with various crops for bonus points.
Support Material
- Teams encouraged to bring supplementary materials like photographs, plans, and charts for machine presentation.
- Use of laptops, binders, and posters permitted for evaluation purposes.
Machine Prototype Cost Evaluation & Manufacturing
- Prototype cost report must detail all relevant cost information for the machine.
- Costing sheets should include a summary and individual sub-assembly sheets for transparency.
- Documentation of costs must include receipts and price tags for items exceeding Rs. 200 at retail prices.
- Late or non-submission of the cost report will incur penalties; teams must use a designated Microsoft Excel template without modifications.
- A comprehensive PDF file with all cost documentation is required for submission to the TIFAN organizing committee.
