[0002] China is a big agricultural country, and the planting area of crops is huge. With the development of technology and economy, people mostly use mechanized operation when harvesting crops, which is efficient and saves time and effort. However, the current harvesting machinery only collects the fruits of crops and leaves the straw, which needs to be manually transported out of the field. People often cannot transport the straw in time due to time constraints, so they often burn it to avoid affecting the next season of cultivation. This often results in smoke spreading, which affects road safety, aviation and shipping, and pollutes the environment.
[0003] According to the search, a Chinese patent with publication number CN201640004U discloses a multifunctional straw chopping machine, which includes a fixed frame, a housing, a transmission and a suspension bracket. The housing is composed of two end plates and an arc-shaped plate. The two ends of the arc-shaped plate are connected to the two end plates, respectively. An inner cavity surrounded by the arc-shaped plate is provided with a cutter shaft. The two ends of the cutter shaft are rotatably connected to the two end plates. One end of the cutter shaft penetrates one end plate and is connected to the output shaft of the transmission through a transmission belt and a transmission wheel. The transmission is installed on the fixed frame, which is installed between the two end plates. The fixed frame and the arc-shaped plate are provided with the suspension bracket. The cutter shaft is installed with a cutter. The inner surface of the arc-shaped plate is provided with a fixed cutter.
[0004] The device has good chopping effect, can better increase soil organic matter and improve soil structure, and is suitable for crops such as corn, sorghum, cotton, rice and wheat in the field.
[0005] However, the device still has the following problems. The device cooperates with the high-speed rotating cutter and the fixed cutter to chop the straw, and then makes the straw fall on the surface of the cultivated land through the action of airflow and centrifugal force. However, the device lacks a corresponding straw covering assembly, and the chopped straw is laid flat on the surface of the cultivated land, which affects the subsequent straw returning effect.
