Alfalfa dehydration silage harvesting technology and harvester

Abstract

The invention discloses an alfalfa dehydration silage harvesting technology and a harvester, and belongs to stockbreeding machines. Through the harvesting technology and the harvester, the field airing is not required, weather influence is avoided, the harvesting is performed at the best cradling period of alfalfa, multiple operation links of harvesting, dehydrating, cutting up, compacting and bagging and the like are finished at a time, the operation processes are reduced, the harvesting time is shortened, the investment cost on the machine is lowered, and the labor force is saved; and meanwhile, prepared silage alfalfa is small in package and is convenient to carry, and the commercialized production is easy to realize. Squeezed juice can directly flow into the field as liquid fertilizer or can be collected to feed flocks and herds, poultry and the like.

Description

technical field [0001] The invention belongs to the field of animal husbandry machinery, in particular to a technique for harvesting alfalfa dehydrated silage and a harvester. Background technique [0002] With the development of animal husbandry, alfalfa is more and more widely used as forage grass with high protein content. Since alfalfa loses more nutrients in the process of making hay bales, the technology of ensiling alfalfa is gradually popularized and used. [0003] Traditionally, the method of alfalfa silage is mostly semi-dry silage technology. After harvesting in the field, it is naturally dried for 24-36 hours. When the water content in the stems and leaves reaches 45%-65%, it is transported back from the field and cut into 2-3cm long pieces. , using silage towers and silos to fill materials and complete fermentation, which not only requires fixed facilities, sufficient transport capacity and a lot of labor, but also easily causes secondary fermentation, resulting...

Problems solved by technology

[0003] Traditionally, the method of alfalfa silage is mostly semi-dry silage technology. After harvesting in the field, it is naturally dried for 24-36 hours. When the water content in the stems and leaves reaches 45%-65%, it is transported back from the field and cut into 2-3cm long pieces. , using silage towers and silos to fill materials and complete fermentation, which not only requires fixed facilities, sufficient transport capacity and a lot of labor, but also easily causes secondary fermentation, resulting in material loss, and a large loss of protein during the drying process, resulting in alfalfa quality. Therefore, it is difficult to achieve large-scale, mechanized and commercial production; at present, stretch film wrapped silage is the most advanced semi-dry silage technology in the world. operation, and then fermented and stored. This method requires a large initial investment, and poor sealing is prone to occur during the silage process, resulting in deterioration of the silage. In addition, the waste stretch film is easy to cause white pollution.
