Description

Knife holder for straw chopping and kneading machine

technical field

The invention relates to the technical field of agricultural machinery, in particular to straw harvesting equipment, and in particular to a tool holder part on the straw harvesting equipment that can chop straw and knead it softly at the same time. the

Background technique

Straw is the general term for the stems and leaves (ears) of mature crops. Usually refers to the remaining parts of wheat, rice, corn, potatoes, oilseeds, cotton, sugar cane and other crops after harvesting seeds. More than half of the photosynthetic products of crops exist in straw, which is rich in nitrogen, phosphorus, potassium, calcium, magnesium and organic matter, etc. It is a multi-purpose renewable biological resource, and straw is also a roughage. It is characterized by high crude fiber content (30%-40%), and contains lignin and so on. Although lignin cannot be utilized by pigs and chickens, it can be absorbed and utilized by ruminant cattle, sheep and other livestock. the

Straw returning to the field is a measure to increase soil fertility that is generally valued in the world today. Straw returning to the field is a method of applying straw (corn straw, sorghum straw, etc.) method. It can improve soil properties, accelerate soil maturation, and improve ^[1] soil fertility. When directly plowing the straw, some nitrogen fertilizer should be applied to promote the straw to decompose in the soil and avoid competition between decomposing bacteria and crops for nitrogen. If the straw can be returned to the field in various ways, it is equivalent to investing 50% of the chemical fertilizers. In actual production, a large amount of crop straw is discarded or even set on fire, which not only wastes resources but also pollutes the environment. Even in some rural areas, straws are harvested and shredded by machines, but the existing harvesters can only chop straws simply and cannot be effectively used as fermented manure or biogas raw materials. Generally speaking, straws are used as fermented manure or The utilization of biogas raw materials requires the straw to be crushed to 2-3 cm and then mixed with organic fertilizers such as pig manure and cow dung. However, the current straw harvesting machines only have the function of cutting and cannot crush and crush the straw to such a short length.

Contents of the invention

In view of the technical defect that the existing straw harvesting equipment cannot chop and knead the straw at one time to meet the requirements of fermentation and retting raw materials, the purpose of the present invention is to provide a straw chopping and kneading machine knife holder, which can knead the straw while cutting and pulverizing. The straw is directly used as fermented manure or biogas raw material, which saves man-hours, improves the utilization rate of straw fermentation, and protects the environment. the
