On the other hand, in the process of moving the onion stem cutting device 100 along the ridge, as the main cutter 160 rotates on the lower surface of the main body 110 facing the ridge, the onion stem that has fallen is erected, and thus the main cutter 160 ) erects and cuts the onion stems that are normally erected or collapsed on the ridge.

In addition, the side cutters 150 provided on both sides of the front of the onion stem cutting device 100 quickly cut the onion stems that have fallen into the furrow and are erected by the lug blade 144 rotated like the side cutter 150. .

Therefore, by the main cutter 160 and the side cutter 150, onion stems normally erected on the ridge as well as onion stems fallen into the ridge or furrow are quickly cut while being erected, so that the cutting efficiency of the onion stem can be maximized.

In addition, the height of the onion stem cut as described above is measured at the measuring plate 180 following from the rear of the main body 110, and according to the measured value, the height of the main cutter 160 and the side cutter 150 is readjusted and cut. The height of the onion stem can be adjusted according to the set value.

That is, when the measuring plate 180 following the main cutter 160 comes into contact with the upper surface of the cut onion stem and flows up and down along the height of the onion stem, at the same time, the hinge bracket 182 pivots the hinge pin 183 As it rotates, the upper end of the hinge bracket 182 passes through a plurality of measurement spheres 187. In this process, the height measurement sensor 188 detects the rotating hinge bracket 182 and measures its positional displacement. At this point, it is possible to detect the height of the corresponding onion stem in contact with the measuring plate 180.

Therefore, according to the measured value, the main cutter 160 is operated by operating the cylinder 170 provided on the wheel 111 or resetting the position and height of the first and second support frames 130 and 131 in the front frame 120. And the height of the onion stem cut by the side cutter 150 can be adjusted.

Although the present invention has been described in detail through specific examples, this is for explaining the present invention in detail, the present invention is not limited thereto, and within the technical spirit of the present invention, by those skilled in the art It is clear that modifications and improvements are possible.

All simple modifications or changes of the present invention fall within the scope of the present invention, and the specific protection scope of the present invention will be clarified by the appended claims.
