Overview 

When we discuss resilient agriculture, we observe how modern technologies have significantly enhanced the sustainability of farming practices. Similarly, let’s explore our own groundbreaking product, the Rabbit Tractor. This innovative vehicle functions as a screw-propelled vehicle (SPV) that gently moves through soil, allowing for proper moisture distribution and oxygenation, weed mulching and tillage process for soil air, moisture and temperature in orchard trees by reducing soil compaction and promoting aeration, it ensures that the soil retains optimal moisture levels while enabling access to essential oxygen by disturbing the upper layer of soil. The compact size of the Rabbit Tractor allows it to maneuver effectively in various crop environments, including orchards and row crops. Its versatility makes it a valuable asset for farmers with diverse agricultural operations. Moreover, the Rabbit Tractor is programmable and compatible with sensor-based control systems, enabling precise operation and data collection.

Purpose 

1. Moisture  Management – The Rabbit Tractor’s screw-propelled mechanism enables it to move through soil by gently tilling the soil and allowing proper aeration.

2. Enhanced Soil Health –  The gentle tilling action of the Rabbit Tractor promotes soil aeration and encourages the decomposition of organic matter, leading to improved soil structure and fertility.

3. Oxygenation and Nutrient Circulation – The Rabbit Tractor’s movement through the soil facilitates the circulation of oxygen, essential for the growth of soil microorganisms and the health of plant roots.

4. Reducing Human WorkForce – The Rabbit Tractor reduces human workforce by automating agricultural tasks such as soil tilling, weed mulching, and tillage processes, optimizing time management, enhancing versatility, ensuring consistent performance, mitigating labor shortages, and enhancing safety on the farm.

5. Consistent Performance – Unlike human labor, which may vary in consistency and effectiveness, the Rabbit Tractor delivers consistent performance in its operations. It maintains precision and accuracy throughout its tasks, ensuring uniformity in processes such as soil tilling and weed control.

What is a Screw Propelled Vehicle (SPV)?

A screw-propelled vehicle (SPV) is a type of vehicle designed to move forward by means of a helical screw blade that rotates and pushes against a medium, such as soil, sand, snow, or water. The screw blade functions similarly to an auger, generating forward thrust as it rotates. SPVs are used in various applications including agriculture, exploration, military operations, and specialized industrial tasks due to their ability to navigate challenging environments effectively.

How Rabbit Tractor Generates Forward Thrust?

A propeller, also known as a screw, moves a vessel by creating thrust. The propeller rotates, creating a difference in pressure between the front and back of the propeller. This difference in pressure creates a force that provides thrust. 

The propeller is connected to an engine or motor that spins it. As the propeller rotates, it acts like a screw that bites into the sand and pulls the vehicle forward. The power generated by the propeller is transmitted to the upper body of the vehicle via the propeller shaft and a thrust bearing.

Screw Propelled Vehicle (Rabbit Tractor) Design?

Screw-drive vehicles have one feature in particular that stands out to give them their strange appearance. Instead of wheels, they’re outfitted with a pair of large, long cylinders with screw-like threads running the length of each.

The engine itself is fixed to the screw cylinders by shafts or chains or other mechanical means to turn them in counter-rotating directions. By making the screws turn in opposite directions from one another, the vehicles can achieve forward (or backward) motion. 

Working Principle 

These vehicles work on a principle called Archimedes Screw, While not completely immersed in mud, snow, or water, screw-drive vehicles are able to push enough of the material to attain motion. So it’s something of an Archimedes Screw in reverse.

To control a screw-drive vehicle, an operator applies more power to either the left or right screw, depending on which direction the driver wants to turn.
Rotational Motion – The power source of a rabbit tractor is an engine or motor which drives the rotation of the screw blade. As the blade rotates, its helical design creates a screw-like motion, pushing against the medium.

Details and Design of the Vehicle

Screw-Propelled Mechanism: At the heart of the Rabbit Tractor is its screw-propelled mechanism, featuring a helical screw blade resembling a large auger. This blade is driven by a power source, such as an internal combustion engine or an electric motor, to generate forward thrust through soil, sand, or other mediums.

Compact Size: The Rabbit Tractor is designed to be relatively compact, allowing it to maneuver effectively in various crop environments, including orchards, vineyards, and row crops. Its size enables it to access tight spaces and navigate through narrow rows with ease.

Precision Control Systems: The Rabbit Tractor is equipped with precision control systems that enable operators to regulate speed, direction, and depth of operation with accuracy. These control systems may include GPS technology for precise navigation and automated steering.
Weed Mulching and Tillage Processes: In addition to soil health and moisture management, the Rabbit Tractor is designed to perform weed mulching and tillage processes effectively. Its screw blade disrupts weed growth and incorporates organic matter into the soil, enhancing soil fertility and structure.
