Description

Cutting and kneading combined caragana crusher

Technical Field

The invention relates to the technical field of crushers, and in particular to a cutting and kneading combined caragana crusher.

Background Art

Caragana is a perennial shrub or semi-shrub of the Leguminosae family. It is a dominant plant for windbreak, sand fixation, water conservation and soil improvement in arid and semi-arid areas in northwest China. It is also an excellent woody feed, rich in crude protein and crude fat, and is an important roughage resource for drought resistance and livestock protection in the Inner Mongolia pastoral area. In order to ensure the vigorous growth of Caragana, stubble operations are required every 3-5 years, which will cause a large amount of Caragana stems to accumulate and easily cause forest fires. In order to realize the resource utilization of Caragana stems and improve economic benefits, it is necessary to effectively crush them to reduce the shape and size of Caragana stems, break the hard lignin and tough cellulose, and provide basic conditions for improving the quality of efficient recycling products of Caragana stems. According to measurements, the natural bulk density of Caragana stems is only 80-100kg/m3, which can reach 180-200kg/m3 after crushing. Therefore, Caragana crushing technology is an important factor affecting the cost of storage and transportation and the economic benefits of resource utilization.

The lignin and hemicellulose contents of Caragana are 47.20% and 17.11% respectively. Crushing Caragana stems by mechanical means can reduce the crystallinity of cellulose, increase the contact area between Caragana and enzymes and microorganisms in the intestines of livestock such as cattle and sheep, and improve the utilization rate of nutrients in Caragana. Compared with other crop straws, the stems are thick and disorderly, with very dense and highly lignified fiber tissue. At present, the crushing of Caragana stems mostly relies on large-scale stubble machines, and the crushing effect is poor. In addition, when using general crushing machinery, it cannot be effectively cut off, which is easy to cause blockage, and the tool wears quickly, which will cause reduced crushing quality and increased energy consumption.
