Description

Vertical whole-plant corn harvesting device

Technical Field

The invention relates to the technical field of agricultural machinery, in particular to a vertical whole-plant corn harvesting device.

Background

The whole plant corn silage is characterized in that corn is harvested between a milk ripening period and a wax ripening period, and then stalks, leaves, ears and other parts of the corn are silaged, so that the whole plant corn silage is easy to store, has high nutritive value and low production cost, and is widely used in cow cultivation. The quality of whole corn silage directly influences the production performance of animals and the economic benefit of enterprises. However, in actual production, most of the existing whole-plant silage corn harvesters in China adopt the mode that the cornstalk, leaves, ears and other parts of corns after corn roots are cut off are fed into the harvesters for bridging, and in the bridging and subsequent devices, the operation processes of flattening compaction of cornstalk, leaves and ears thereof, material cutting, grain crushing, material throwing and collecting and the like are completed at one time. The whole corn plant silage harvesting mode often cannot realize complete breakage of corn kernels, and the corn kernels which are not broken can be completely discharged out of the body after being eaten by dairy cows, so that great waste of nutrient substances is caused. The low corn kernel crushing rate directly affects the quality of whole corn silage. Therefore, the corn ears are independently sent into a seed crushing device for rubbing and rolling, so that the seeds are subjected to the treatment process of cracking and breaking the skin, and then are mixed with materials such as corn stalks, blades and the like which are independently cut, so that the quality of the whole plant corn silage is improved.

The domestic corn harvesting only takes corn ears and stems to return to the field, and the ear and stems are harvested simultaneously, so that the operation performance of the two types of corn harvesting is limited, and the operation performance of the two types of corn harvesting cannot be adjusted according to the growth vigor of crops in the field. Therefore, the whole-plant corn harvesting device which is used for harvesting the corn ears and the corn kernels in a split manner and can selectively crush the corn ears and the corn kernels is designed, so that the use efficiency of the machine tool is improved, and the use performance of the machine tool is better exerted.
