[0004] In order to achieve the above technical objectives, the utility model adopts the following technical solutions:
[0005] A crushing fan for transporting corn stalks and debris comprises a shredding shell, a fan shell, a driving pulley, a fixed knife, a fan blade assembly and a moving knife, wherein the fan shell is fixedly connected to the side end of the shredding shell and forms an integral body with the shredding shell, a rotating shaft is rotatably connected to the integral body, the rotating shaft runs through the integral body, and the driving pulley, the fan blade assembly and the moving knife are respectively fixedly connected to the rotating shaft, the driving pulley is located outside the integral body, the fan blade assembly is located in the fan shell, the moving knife is located in the shredding shell, and the fixed knife is fixedly connected to the inner wall of the shredding shell.
[0006] Preferably, an air regulating plate is provided on the fan housing.
[0007] Preferably, a maintenance observation panel is provided on the shredder housing.
[0008] Preferably, a fixed knife and a movable knife are used to achieve two-way shredding.
[0009] Preferably, the fan blade assembly adopts a suction structure to discharge the chopped straw and other debris.
[0010] As a preferred method, the air volume is adjusted by an air regulating plate to enhance the adaptability to different regions, different agronomy and maturity.
[0011] The utility model discloses a crushing fan for lifting corn stalks and debris. The technical solution adopts a fixed knife and a moving knife combination structure to chop corn stalks, debris and the like. The fan blades in the rotating shaft assembly are used to effectively discharge the chopped corn stalks and debris using a suction structure, and multiple unit air adjustment plates are used to adjust the air, so as to better adapt to harvesting in different regions, different agronomy and different harvesting stages, truly realize the use of one machine in multiple regions, better solve the optimal solutions for different regions and different agronomy, and have a good use effect in corn harvesting.
