Technical Field
The invention relates to a corn straw harvesting table, and belongs to the technical field of agricultural machinery.
Background
At present, three modes are mainly used for recycling corn stalks in China: returning to the field, ensiling and yellow storage. In corn straw silage, it is generally classified into straw shredding and collecting and straw shredding and baling. "yellow storage" is a term used in agriculture to store crop residues such as corn stover. Such residues, if not properly treated after harvesting, may have negative environmental impact, such as contaminated soil and water sources. Therefore, silage is an effective method of treating these residues, converting them into biomass energy, such as organic fertilizers, or can be used as animal feed.
The process of ensiling involves shredding, compacting, sealing the remainder of the crop, such as corn stover, and then fermenting under suitable conditions. During this process, microorganisms decompose these residues, producing energy and useful compounds, such as organic fertilizers and animal feeds.
The yellow storage not only can reduce the influence on the environment, but also can provide an additional income source for farmers. In addition, silage can also be used as a renewable energy source, as it can produce biomass energy, which is a clean, renewable energy source.
Most of the prior art mixes yellow storage with soil by returning to the field, but the yellow storage is easy to ferment in the field when the yellow storage meets rainy and high-temperature weather, so that the influence of seedling burning and the like on the crops planted in the later period is generated.
In the process of implementing the embodiment of the invention, the inventor finds that at least the following technical problems exist in the background technology:
if silage is directly processed by a silage machine, the two types of straws have different hardness and cannot be well compatible in the use process, and for the problems, a harvesting device for maize straw silage is developed.
