Semi-Autonomous Multi-Function Tool Carrier for Agricultural Research
Notice bibliographique
Résumé
This report outlines the process of designing a semi-autonomous multi-function tool carrier to be used for agricultural research. This project is being performed for R-Tech Industries, on behalf of team 20 from the University of Manitoba. The report contains information on project objectives and constraints, concept development, and a detailed analysis of the final tool carrier design. Design sections of the report include concepts considered, component design processes and justifications, as well as structural analysis on components to ensure all components are strong and reliable. The objectives for this project were to design a tool carrier unit that could replace conventional agricultural equipment in test plots, which are used for agricultural research. Emphasis was placed on designing a unit that was safe, efficient, environmentally friendly, performed better than conventional equipment, and provided R-Tech with an advantage in the semi-autonomous agricultural research tool carrier market. Deliverables for this project include a CAD model of the unit, a detailed BOM with budget included, and a final design that is well analyzed to ensure reliability. The tool carrier design is split up into four distinct sections: track design, hydraulic design, powertrain design, and frame design. The unit is propelled by a set of two custom-designed tracks with a leaf-spring suspension system. The tracks are connected by a steel-tube space frame, which is designed to provide an adjustable ground clearance between 30”-54” to avoid crop damage. Adjustable ground clearance is completed by a hydraulically-powered sliding subframe, which attaches implements to the unit with a 3-point hitch mechanism. This allows implements to be lifted or lowered over a 24” range, allowing them to operate at an optimal height. Each track is powered by an electric motor, which draws energy from a 52 kWh lithium-cell battery pack. The motors produce 8 horsepower continuously, and up to 19 peak horsepower. Mechanical power is transmitted from motors through gearboxes and chain drives to the tracks, propelling the unit. The final design of the tool carrier weighs 5700 lbs, measures 100” wide and 98” long, with an adjustable height of 85”-109”. Implements are mounted within the footprint of the unit and may be up to 62” wide, and lifted or lowered 24” in 15 seconds. The two motors produce a total of 16 HP to the tracks and can operate for roughly 4 hours at such power levels. Range may be supplemented with an additional on-board gasoline generator, allowing the unit to run for over 8 hours continuously. The total tool carrier costs $56,882.20, excluding manufacturing and electrical system costs.
