Design and construction of a multi-purpose agricultural rotator with movable arms

Tillage operations are very important in various aspects, including improving the physical quality of the soil, maintaining moisture, increasing organic matter, and reducing erosion, and play a fundamental role in providing a suitable substrate for optimal plant growth... In this regard, the design and construction of a multi-purpose rotivator with the aim of simultaneously performing tillage and planting operations creates a revolution in increasing productivity, reducing fuel consumption, time, and total cost of production. This device, with its combined mechanisms, is capable of performing operations such as breaking up clods, aerating the soil, preparing the seedbed, and digging adjustable furrows simultaneously. The double-sided folding structure and design compatible with road transport conditions are other important features of this advanced tiller. In addition to the technical advantages, using this device with modern technologies will help automate agricultural operations, reduce resource losses (such as water, energy, and fertilizer), and adapt to the principles of sustainable agriculture. Due to the lack of a similar domestic model and its affordable price compared to foreign models, this device can play an effective role in the development of agricultural mechanization in the country. Thus, the multipurpose tiller, as an efficient, smart, and economical tool, will pave the way for increasing productivity, conserving resources, and achieving sustainable development goals in modern agriculture.
