Iowa Patent of the Month – October 2023

Kooima Company has a long history in manufacturing replacement parts for agricultural machinery like combines and harvesters. With their experience in the industry, the company has designed and patented a new loader-mountable compost turning system.

This innovative apparatus is designed to be mounted on the support arms of a loader, allowing for efficient turning of composting materials in a windrow while keeping them neatly contained. The compost turning apparatus consists of a mobile base with an elongated frame that creates a windrow tunnel through which composting materials pass. The frame is strategically designed to prevent the inboard portion from moving over the composting materials, ensuring the materials are properly turned without interference.

At the heart of this invention is a rotor, which is rotatably mounted on the mobile base and extends across the windrow tunnel. The rotor is equipped with multiple paddles that efficiently mix and aerate the composting materials. A rotor drive assembly, powered by a hydraulic motor connected to the loader’s hydraulic system, controls the rotation of the rotor, allowing for precise and effective compost turning.

One of the standout features of this compost turning apparatus is its ease of installation. The inboard portion of the frame is designed to engage the support arms of the loader, making it simple to mount and dismount the apparatus as needed. This user-friendly design ensures that the compost turning apparatus can be readily integrated into existing equipment setups.

By addressing the challenges associated with composting materials management, the company is contributing to more sustainable and efficient composting practices. This loader-mountable compost turning apparatus has the potential to streamline composting operations and reduce environmental impacts, making it a noteworthy advancement in the field.
