Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of high-protein woody feed processing, in particular to a harvesting machine for high-protein woody feed with high safety. Background Art
[0002] Protein mulberry, also known as fodder mulberry, is a hybrid mulberry selected and bred by scientists from Beijing Sangliang Technology Development Center in 1998 from 28 mulberry varieties across the country. The leaf protein content of Yajin protein mulberry (fodder mulberry) reaches up to 36%, and the branch protein content reaches 28%. Therefore, protein mulberry accounts for a large proportion in high-protein woody feed.
[0003] For feeding of protein mulberry, the stems and leaves of the plants are harvested together, not just the leaves, and they need to be mowed every year. Mulberry plants can be harvested 1 to 2 times in the year of planting, and 3 to 5 crops can be harvested starting from the next year. The seedlings must be harvested when they grow to about 70 cm to prevent the branches from becoming lignified. Agricultural harvesters are generally used for harvesting. When the protein mulberry is harvested mechanically, if there are rod-shaped metal materials in the protein mulberry field (such as flag poles, or materials left out when building scarecrows), the harvesting machinery will be damaged, and the safety of the equipment itself will be too low. Some rod-shaped metal materials with poor hardness will be torn into pieces by the powerful spiral leaves on the front side of the harvester and enter the protein mulberry storage compartment of the machine. The mixing of metal debris with protein mulberry is not conducive to subsequent processing. Utility Model Content
