Description

  The present invention relates to a cutting device for cutting the roots of crops such as onions in the ground.

Agricultural crops need various care from sowing (or seedling planting) to harvesting. This care is called management in farming. This management includes cutting the roots of crops such as onions in the ground.
A technique for efficiently performing the root cutting work of onion has been proposed (see, for example, Patent Document 1).
No. 4-4495 (Fig. 1)

Patent document 1 is demonstrated based on the following figure.
FIG. 7 is a side view of a conventional onion rooting machine. The onion rooting machine 100 is provided with a lifting link at the front of a four-wheeled traveling vehicle body 103 having a rear wheel 101 and a front wheel 102. A bracket 105 is provided via 104, and a leaf sorter 106 and a front auxiliary wheel 107 for scraping onion leaves and stems are provided on the bracket 105. Further, the sub bracket 108 extends downward from the bracket 105, and a knife 110 is provided on the sub bracket 108.

FIG. 8 is a perspective view of a conventional knife. The knife 110 includes a horizontal strip portion 111 and vertical strip portions 112 and 113 extending upward from both ends of the horizontal strip portion 111, respectively.
FIG. 9 is a cross-sectional view taken along line 9-9 of FIG. 8, and the horizontal band plate portion 111 is provided with a first blade 114 and a second blade 115. These blades 114 and 115 are quenched. Reference numerals 116 and 116 denote quenching layers. Since there are the hardened layers 116, 116, the hardness is increased. Even if the first blade 114 or the second blade 115 hits a hard object such as a stone, there is no fear of the blade being chipped.

FIGS. 10A and 10B are diagrams for explaining how to use a conventional knife. FIGS. 10A and 10B show how the roots of a plurality of onions 121 are cut with the knives 110B and 110C.
As shown to (a), the onion 121 is planted by the intercostal space L1. L1 is, for example, 300 mm. The vertical strips 112 and 113 need to be arranged between the onion 121 and the onion 121. Therefore, the width of the knife 110B is set to 900 mm corresponding to three times L1.

  On the other hand, for the convenience of the seedling transplanter, as shown in FIG. For example, L2 is 270 mm. In this case, the width of the knife 110C is set to 810 mm corresponding to three times L2.

Since the knife 110 is baked, it cannot be cut and welded to change the width from 900 mm to 810 mm. This is because baking is restored by welding heat.
Therefore, conventionally, it is necessary to always have two or more types of knives 110B and 110C having different widths. This increases the cost of procurement of knives and increases the storage space in the warehouse, so countermeasures are required.
