Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a cutting device for cutting a crop,

The present invention relates to a crop stem cutting apparatus for cutting a stem of a crop such as sweet potato or potato, and more particularly, to a crop stem cutting apparatus for cutting a stem of a crop such as sweet potato or potato, The present invention relates to a crop stem cutting apparatus having a moving means for a weft so as to be able to solve a problem caused by a stem and to perform an operation while being easily moved in a valley having various widths.

Generally, most leguminous crops such as potatoes harvest only the roots, and the stem is used as feed or compost for livestock.

In particular, in the case of a crop having a stem of a vine such as a sweet potato, harvesting using a harvesting machine is advantageous only when the stem is removed before harvesting.

In addition, if the stem of the crop is cut to a predetermined size after the harvest of the crop, the stem of the crop can be collected separately and removed, so that the work for the next crop can be carried out.

Various techniques for cutting and removing trunks and vines of crops as in the following patent documents are provided for various reasons.

"Vine removal device" provided in Korean Patent Application Laid-Open No. 10-2009-0073967, "Vine Removal Device" provided in Korean Patent Application No. 10-1060319, "KRC Patent No. 10-1173005" &Quot; and "Bulb Crop Cutting Apparatus" disclosed in U.S. Utility Model No. 20-2011-0011528.

Conventionally, the constitution of a general crop stem cutting apparatus for cutting a crop stem includes a body which is detachably attached to an agricultural machine such as a cultivator or a tractor, a power transmission device for transmitting power from the farm machine, A stem cutting device for cutting the crop stem by rotating the stem and a moving wheel provided on both sides of the body for moving along the furrow so as to be easily moved, .

However, in the conventional crop stem cutting device, the width of the troughs is not constant, so that the moving wheels can not move along the troughs. When the tread wheels of one side are raised to the troughs, There are disadvantages which are not achieved well. On the other hand, there is a problem that, when cutting the crop stem, the cutting wheels are tilted along with the movement of the wheels to break the crop to be harvested.

(KR) Patent Publication 10-2009-0073967 (KR) Patent No. 10-1060319 (KR) Patent No. 10-1173005 (KR) Public utility model 20-2011-0011528
