Novel biomass fuel briquetting machine

Disclosed is a novel biomass fuel briquetting machine. A power device and a pair of rolling drums are arranged on a framework of the novel biomass fuel briquetting machine, a plurality of squeezing holes are arranged on each rolling drum, pressing pieces and the squeezing holes on the two rolling drums are correspondingly staggered with one another, axes of the two rolling drums are parallel to each other and are adjacent to each other, a transmission mechanism is connected among the two rolling drums and an output shaft of the power device, and two groups of adjustable support mechanisms mounted on the framework are respectively arranged on peripheries of two ends of each rolling drum and support the rolling drum. The two rolling drums are supported by the adjustable support mechanisms on the framework, and a gap between the two rolling drums can be adjusted by means of adjusting the adjustable support mechanisms, and can be adjusted after the two rolling drums are used for a period of time and are worn, so
