It is designed to be rear-tractioned by a four-wheel tractor with a horsepower ranging from 80 to 120. The machine is connected to the tractor via the three-point suspension system. Before starting the machine, the excavation depth is adjustable. As the tractor moves forward, it powers the stone picker machine, causing the excavation knife to penetrate the soil, collecting stones and soil that are then conveyed to the front chain row. Subsequently, the material is transported to the rear roller, which rotates to separate the soil, and the stones are loaded onto a conveyor belt for removal.

The machine efficiently separates crops from the soil. It gathers gravel and conveys it to one side through a conveyor belt or directly loads, separates, and cleans it, resulting in high work efficiency. Additionally, the machine offers the option for automatic loading or the installation of a container at the rear, reducing the need for manual handling.
Moreover, this machine demonstrates its versatility in various applications, such as land reclamation in mining areas, remediation of mudslide-affected regions, rehabilitation of water-damaged farmland, stone removal in landscaping projects, and cleaning of construction waste. This stone crusher effectively addresses the challenge of rock removal for farmers and provides valuable solutions for a wide range of tasks.
