Problems solved by technology

However, in the prior art, the roller-die straw briquetting machine has the following disadvantages: 1. Because the material is forced to be extruded through the shaft-wheel transmission technology, it has high power, high energy consumption, and low output; 2. The pressure is not easy to control. Excessive extrusion force will cause traffic jams, which will take a lot of work and effort and affect work efficiency. Excessive extru

Abstract

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.

Description

technical field [0001] The invention belongs to the field of biological energy, and in particular relates to a speed-variable straw briquetting machine and a method for forming straw briquettes. Background technique [0002] my country is committed to transforming discarded crop stalks into high-grade biomass energy to replace some fossil fuels such as coal and petroleum, so as to alleviate the energy shortage in rural areas, increase farmers' income, and achieve sustainable development of rural energy. As an important bioenergy resource, straw is abundant and cheap. After compressing the straw, its density increases [0003] 8~10 times, the combustion value increases, and the emission of dust and other indicators after combustion is lower than that of coal. It can reduce CO2 and SO2 emissions, reduce the greenhouse effect, and have obvious environmental protection benefits. It can be used as a high-grade energy product. [0004] At present, straw forming machines of vario...
