Agricultural and forestry wastes are needed in biogas power generation, and crushing equipment is needed to crush the agricultural and forestry wastes.

[0003] After searching, the patent number is CN110523517A, and the name is an invention of a safe anti-clogging agricultural and forestry waste crushing equipment, which includes a first connecting pipe. Through research and analysis, it is found that although it has the advantage of preventing a large amount of waste from being blocked in the first connecting pipe, it still has the following disadvantages to a certain extent.

[0004] For example, because it does not have the function of conveniently conveying and crushing materials during use, when agricultural and forestry waste is crushed, the agricultural and forestry waste cannot be quickly conveyed into the equipment for crushing, which reduces the efficiency of crushing, and it does not have the function of good crushing effect, so when agricultural and forestry waste is crushed, it cannot be fully crushed, so that the crushed agricultural and forestry waste particles are larger, which reduces the crushing effect. In order to solve the above technical problems, we have designed a crushing equipment for agricultural and forestry waste biogas power generation that is easy to transport. Utility Model Content
