Description

Blade shredding device and harvester
Technical Field
The invention relates to the field of agricultural machinery, in particular to a blade chopping device and a harvester.
Background
Mulberry leaves are leaves of mulberry trees and are the main food of silkworms. The length of the complete mulberry leaf is about 15 cm, the width is about 10 cm, the length of the petiole is about 4 cm, the heart shape of the base part of the leaf is heart-shaped, the top end is microtip, the edge is provided with sawteeth, and the veins of the leaf are dense, white and soft; the old leaves are thick, dark green, the tender leaves are thin, yellow green, crisp and easy to handle, light smell and slightly bitter and astringent taste. The mulberry leaf not only has the efficacies of dispelling wind and heat, clearing lung and moistening dryness, and clearing liver and improving vision, but also has unique curative effects on cold, lung heat and dry cough, dizziness and headache, and conjunctival congestion and fainting. In recent years, people find that the mulberry leaves have rich nutrition value of the buds, and the buds of the mulberry leaves are made into a vegetable type, so that the mulberry leaves have the value of food therapy and are popular. China is a big mulberry planting country, agricultural scientists in China continuously and deeply research and obtain rich results in the aspects of selective breeding of improved mulberry seeds, fertilizer for mulberry, prevention and control of mulberry diseases and insect pests, management of mulberry gardens and the like, and at present, thousands of mulberry varieties are collected, sorted and newly bred. Among them, the protein mulberry is a kind of mulberry favored by modern mulberry growers.
The protein mulberry is also called feed mulberry, and the mulberry leaves contain abundant carbohydrate, protein, fatty acid, cellulose, vitamin and mineral elements. The lignified fiber of the leaves is extremely low, the crude fiber is 8-15%, the soluble carbohydrate is 20-25%, the crude protein is 23-30%, the crude fat is 5%, the amino acid types are complete and reach 18, and the amino acid types account for more than 10% of the dry matter of the mulberry leaves. Of these amino acids, the essential and nonessential amino acids for animals account for more than half of the total amount, and particularly, the content of lysine, methionine, cystine and glutamic acid is high, so that the feed has high nutritional value. The protein mulberry leaves are rich in mineral nutrition and mainly contain 8 mineral elements according to the determination, so that the protein mulberry leaves as the feed have important significance on the growth and development of animals. In practical operation, when the protein mulberry leaves and tender stems are used as livestock feed, the protein mulberry leaves and tender stems are generally cut into pieces with the length of about 1-2cm, but because the protein mulberry cutting in China is still in a full-manual stage at present, the labor intensity of mulberry farmers is extremely high, and the working efficiency is extremely low.
