The invention provides a speed changing type
straw briquetting
machine and application of the speed changing type
straw briquetting
machine. According to the scheme, an original high-power motor is changed into two low-power motors. The motors are in transmission connection with a main shaft through a speed changing box. A briquetting wheel is locked and fixed through a briquetting wheel support gear sleeve and an adjusting pulling block. A second module is additionally arranged on the basis that a first module outwards extends. A
machine oil
lubrication channel is formed in a machine body of the briquetting machine, the machine oil
lubrication channel passes through the main shaft and each bearing base in the machine body of the briquetting machine, and an
oil pump provides power to form the
lubrication circulation. The speed changing type
straw briquetting machine has the advantages of being low in
energy consumption, low in labor strength, even in
extrusion, free of machine blocking, high in yield, high in efficiency, convenient to maintain and the like. The speed changing type straw briquetting machine is suitable for briquetting maize straws, cotton stalks, peanut shells,
saw dust, soybean straws and the like, the fuel density of rod-shaped compact maize straw briquetted fuel obtained by the speed changing type straw briquetting machine after the rod-shaped compact maize straw briquetted fuel is briquetted is 1.1-1.3g / cm<3>, and the briquetting effect is good.
