Technical Field

[0001] This invention relates to the field of biomass briquetting and pelletizing equipment, specifically to a briquetting machine with an integrated motor. Background Technology

[0002] Biomass pellets are an environmentally friendly and renewable energy source. The production process requires a pelletizing machine to compress biomass raw materials into high-density pellets. Traditional pelletizing machines typically consist of a pellet pressing device, a motor drive system, and a transmission device. The motor, as the core power source, is usually externally mounted. However, this requires a dedicated motor base and coupling, along with a speed reducer, increasing the complexity of installation and debugging. Furthermore, the external motor structure requires additional space, leading to a larger overall equipment size, which is detrimental to miniaturization and portability. Additionally, the connection between the motor and the pellet pressing device via belt or gear transmission inevitably results in energy loss during transmission, affecting the overall efficiency of the equipment.
