Description

Automatic Double Feeding Line Type Corn Cutting Device {AUTOMATIC CUTTING APPARATUS FOR CORN}

In the present invention, corn kernels grow around a cob extending from a stem connected to a stem of corn, and corn with the whiskers and bracts removed is divided into two rows on the left and right in a state in which the beard and bracts are wrapped around it. This is a technology related to a double-feeding line-type automatic corn cutting device that allows the root of corn to be cut uniformly while being transported at the same time.

In general, corn, as we know it, stands upright on the stem, grows to 1.5-2.5 m in height, and is generally not pruned. The leaves run opposite to the stem. Male spikelets hang at the tip of the stem, and female spikelets hang on the leaf axil at the center of the stem, and 10 to 20 rows of female spikelets are arranged vertically on the tip of the ear shaft wrapped in several bracts. At this time, the female spikelet corresponds to the corn kernels.

In recent years, this corn has been widely used for commercial or industrial purposes, such as canning, depending on its state in addition to food.

After these corns are fully ripe, at the harvest season, workers pick and harvest by hand, peel off the bracts before processing or eating, and then use other cutting tools to use other cutting tools to attach the stamens or the remaining parts of the bracts, that is, the stems to which the bracts are connected. Part or rough parts are trimmed and polished by workers one by one.

Devices that can do this automatically include:
