Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of agricultural equipment technology, especially, relate to a tobacco stem smashing device and tractor. BACKGROUND

[0002] Tobacco stem is a by-product after tobacco planting, and if handled properly, it can be used as an important biological resource. After the end of tobacco picking, burning the tobacco stem will pollute the atmosphere. Tobacco stem is part of tobacco, and a large number of bacteria parasitize in the stem. If it is returned to the field, not only will it spread black shank disease, anthracnose disease, and other diseases, but also will cause resource waste and pollution of tobacco field, so it cannot be returned to the field as fertilizer like other straw. If it is burned on site, it will have the risk of causing fire. However, tens of thousands of tons of tobacco stems are produced every year. Most tobacco farmers choose to chop the tobacco stems in the field and abandon them in the field, ditches and rivers, becoming agricultural waste. If not disposed of in time, on the one hand, it will affect the water source, and on the other hand, it will provide a growth place for diseases and pests, leading to an increase in the number of harmful organisms. In addition, because tobacco stems carry viruses, when they rot and enter the soil, they will cause the spread of viruses, thereby affecting the growth of crops the following year.

[0003] At present, a large tractor driven tobacco stem pulling machine can be used to pull out the tobacco stem, but due to its large turning radius and poor mobility, it is only suitable for relatively flat areas and can only pull out the tobacco stem, and cannot complete the tobacco stem crushing, collection and transportation work.
