Description

TECHNICAL FIELD

[0001] The utility model belongs to the straw collection field, concretely relates to a small -size harvester changes straw collection granulating device. BACKGROUND

[0002] Crop straw is regarded as a valuable biomass resource because it is rich in carbon, nitrogen, phosphorus, potassium, calcium, magnesium, lignin and other nutrients. The difficulty of current straw resource utilization is the lack of harmless and effective reduction technology and supporting machinery for on-site utilization. The cost of off-site utilization is high, and the market acceptance is low. The development of in-situ reduction and harmless equipment is the key to the realization of on-site and off-site diversified utilization of straw resources. Germany has developed a mobile straw in-situ collection-pelletizing machine in recent years, which can collect and crush straw in the field and complete the pelletizing process at the same time. The straw pellets produced can be spread in the field on site or collected for other uses, providing great convenience for on-site and off-site diversified high-value utilization of straw. Similarly, for the northeast region, China has developed a corn straw in-situ collection and rapid pelletizing machine. The pelletized straw has been proven to have good quality, large amount of straw, rapid decomposition of straw in the same year, rapid improvement of soil organic matter, and significant increase in crop yield.

[0003] However, the current domestic and foreign mobile in-situ pelletizing machine for straw mainly targets relatively flat and suitable for mechanization conditions, and has problems such as large equipment volume, high power and high cost. In particular, the existing mobile in-situ straw pelletizing machine on the market in China is mainly wheel type, with a huge volume and can only pelletize corn straw. Small-sized harvesters, such as the 4LZT-6Z1 track type full-feeding grain combine harvester produced by Zoomlion Agricultural Machinery Co., Ltd., are commonly used in the south, but they can only separate the grains, and the straw can only be completely discharged in the field, which requires further manual processing and consumes time and effort.
