Problems solved by technology

"Corn straw collection and storage new technology and selection of supporting equipment" [Wang Dezhong. Corn straw collection and storage new technology and selection of supporting equipment [J], Mechanization of Rural and Pastoral Areas, 2011, (1): 26] proposed a " Whole corn stalks—cutting into filaments—transportation by trailer—compression packing—stacking storage—feeding cattle and sheep or industrial utilization” is a new corn stalk collection and storage process, but this method fails to fully obtain corn stalks. use of
(5) Manpower issues
The production of micro-storage, silage and ammonification is mostly carried out in the busy season, that is, after the field crops are harvested and stored. Farmers are busy with harvesting crops, and there is no way to recruit people to collect, transport and do the basic work of micro-storage, silage and ammonification

Embodiment 1

[0047] A storage method for corn stalks, wherein: the storage method includes the following steps:

[0048] 1) Use agricultural harvesters to harvest corn stalks in the farmland;

[0049] 2) The harvested corn stalks are torn, crushed and separated by the corn stalk husk, pulp and leaf separation device installed in the agricultural harvester to obtain separated corn stalks, leaves and corn stalks;

[0050] 3) The corn stalks obtained in the previous step are dried in the field or air-dried until the moisture content is 15-45%, collected and bundled as fiber raw materials for papermaking, power generation or fiber; while the corn stalks and leaves can be recycled as feed or Lactic acid or ethanol is produced by fermentation.

[0051] It is key to realize that the collection and storage method of the present invention reasonably selects supporting equipment. see figure 1 and figure 2 , the agricultural harvester that the present embodiment adopts comprises chassis 4, power...

Embodiment 2

[0064] A storage method for corn stalks, wherein: the storage method includes the following steps:

[0065] 1) Use agricultural harvesters to harvest corn stalks in the farmland;

[0066] 2) The harvested corn stalks are torn, crushed and separated by the corn stalk husk, pulp and leaf separation device installed in the agricultural harvester to obtain separated corn stalks, leaves and corn stalks;

[0067] 3) The corn stalks obtained in the previous step are dried in the field or air-dried until the moisture content is 15-45%, collected and bundled as fiber raw materials for papermaking, power generation or fiber; while the corn stalks and leaves can be recycled as feed or Lactic acid or ethanol is produced by fermentation.

[0068] On the basis of Embodiment 1, the agricultural harvester used in this embodiment further adds a straw husk dispersion device 6 and an anti-blocking device 7, see image 3 , its operation process is the same as embodiment 1.

[0069] The straw h...

Embodiment 3

[0074] A storage method for corn stalks, wherein: the storage method includes the following steps:

[0075] 1) Use agricultural harvesters to harvest corn stalks in the farmland;

[0076] 2) The harvested corn stalks are torn, crushed and separated by the corn stalk husk, pulp and leaf separation device installed in the agricultural harvester to obtain separated corn stalks, leaves and corn stalks;

[0077] 3) The corn stalks obtained in the previous step are dried in the field or air-dried until the moisture content is 15-45%, collected and bundled as fiber raw materials for papermaking, power generation or fiber; while the corn stalks and leaves can be recycled as feed or Lactic acid or ethanol is produced by fermentation.

[0078] Described agricultural harvester is with embodiment 1.

[0079] In the obtained fiber raw material for papermaking, relative to the dry raw material, the mass percentage of water-soluble sugar in the corn stalk husk is 12.15%, the mass percentag...

Abstract

The invention relates to a corn stalk harvesting and storing method, comprising the steps of 1) harvesting corn stalks in a farmland by utilizing a farm-oriented harvester; 2) during harvesting, separating the harvested corn stalks by adopting mechanical means of extruding, grinding, twisting, tearing, smashing by stirring or rubbing into silks, so as to obtain the separated corn stalk pulp, leaves and corn stalk skin, and preferably tearing, smashing by stirring and separating by virtue of a crop stalk separating device arranged in the farm-oriented harvester to obtain the separated corn stalk pulp, leaves and corn stalk skins; and 3) collecting the corn stalk skins obtained in the step (2) as fibrous materials used for papermaking, generating and fibrous raw materials used for fibers when moisture content is 15-45%, and the corn stalk pulp and leaves can be recycled as feed or are used for producing lactic acid or ethanol by virtue of fermentation. The corn stalk harvesting and storing method provided by the invention can realize the whole process from harvest to storage of the corn stalks by virtue of field operation only, so that manpower and materials are saved; and tearing, smashing by stirring and separating of the corn stalk skins and the corn stalk pulp also can be realized, and the aim of fully utilizing the corn stalk can be achieved.

Description

technical field [0001] The invention relates to a method for processing corn stalks, in particular to a method for collecting and storing corn stalks. Background technique [0002] Corn stalks and wood belong to renewable lignocellulose resources accumulated through photosynthesis, but wood is used in large quantities, while corn stalks are burned or discarded in large quantities. The important reason is that the inhomogeneity of corn stalk biological stalks, that is, the skin, pulp, leaves, etc. each account for a certain proportion, and the chemical composition and fiber morphology of each part are very different. The corn stalks that the present invention adopts are respectively taken from Yanshou County, Heilongjiang Province and Gongzhuling City, Jilin Province. These two kinds of stalks are analyzed to obtain data such as Table 1. From Table 1, it can be seen that the two parts of leaves and pulp account for the total amount of corn stalks. more than 60% of. The mech...
