BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a knife such as a sickle used to separate vegetables from roots when harvesting them in a field.

[0002]

2. Description of the Related Art Conventionally commonly used sickles have an arc-shaped blade fixed to the tip of a handle that forms a straight rod, and a blade is provided on the inner side of the blade.

[0003]

[Problems to be Solved by the Invention] Using the above-mentioned conventional sickle, in order to harvest a headed vegetable having a thick and hard rhizome,
I had to pull the sickle's blade forward and separate the vegetables from the rhizome. For such work, if you do not consider the size and hardness of the rhizome of vegetables,
It was dangerous to the human body and required considerable strength and skill.

[0004]

The present invention is to solve the above-mentioned problems by the following constitution. That is,
A handle body having a side-face V-shape, and a blade body axially fixed to the tip of the handle body, bent in an arc shape in a direction opposite to the V-shape shape, and provided with a blade outside the arc shape. It constitutes a knife such as a sickle.

Further, the blade body is configured such that the shaft stopping portion serves as a pivotal support portion so that the blade body can be bent so as to be positioned inside the handle body, and the blade body can be adjusted to an appropriate position and restrained depending on the application.

[0006]

[Operation] With the above configuration, to harvest vegetables,
It is used by adjusting the angle of the blade according to its application. That is, the sickle is applied to the root of the vegetable to be used and pressed in a direction away from the human body to separate it from the root. (Usage mode according to FIG. 3) Next, when the vegetables are cut from the roots, the cut portions become uneven, and when the packaging work as a product cannot be completed completely, the blade body is set to an easy-to-use angle as shown in FIG. Adjust and finish the cut.

Furthermore, when the sickle is used in a conventional method such as cutting out, the angle is set accordingly. As described above, the basic type can be used for push-cutting work, and the universal system can be adopted by adjusting the angle to the individual's specialty.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings. Reference numeral 1 denotes a handle body having a V-shaped side surface, and a grip portion 2 and a blade body support portion 3 are made of resin.
The grip portion 2 is provided with a groove portion 4 on the side surface in the lengthwise direction so that a ceramic grindstone or the like can be held if necessary. Further, the grip portion 2 is provided with a projection and a projection 6 outward inwardly and outwardly in a non-slip uneven portion 5 and a V-shaped bent portion.

Next, the blade support portion 3 has a cavity 7 on the side surface.
Is provided to accommodate a pin or the like, which will be described later, and the split groove 8 is provided from the tip. A push washer 11, which is provided on the side surface, is fixed to the split groove 8 by a thumbscrew 10 penetrating the shaft core 9 from the side surface. Further, a plurality of small holes 12, 12 ... Are arranged in an arc shape with a space from the shaft core 9, and the pin 13 is inserted by selecting one of these small holes.

Then, 14 is formed into an arc shape and a blade 15 is provided outside.
It is a blade provided with. The blade 15 is provided over the entire arc shape. This blade 14 has a shaft hole 16 in one of its lengthwise directions and a plurality of semicircular cutouts 1 on its outer end surface.
7 and 17 are provided. The blade body 14 is inserted into the split groove 8 so that the shaft core 9 penetrates the shaft hole 16 and is pivotally supported by a thumbscrew 10 for positioning, and further, one of the notches 17 has a small hole. Any one of the pins 13 is inserted to position and fix the blade 14 with respect to the handle 1. In this case, the small holes 12, 12, ... And the notch 17,
17 ... may be a plurality of both, or one of them may be one. Most preferably, the number of small holes 12, 12 is two, and both small holes are preferably 1.5 times the gap between the notches.

In this way, the pin 13 is inserted, the press washers 11, 11 are further applied from the outside, the shaft core 9 is penetrated, and the thumbscrew 10 is tightened to fix the blade body 14 and prevent the pin 13 from coming off. It can also be used as a combination.
In addition, it is preferable that a spare of the above-mentioned pin 13 or a needle or the like be inserted in the cavity 7 to prevent the pin 13 from falling off.

[0012]

[Effects of the Invention] Since the present invention pushes and cuts the root of a heading vegetable having a large and hard rhizome among vegetables and the like, even if the thickness and the hardness are changed, the force is exerted in the human body direction. It is extremely safe because you can work without it. Further, since the angle of the blade can be adjusted and used, it is suitable for finishing work of the cut portion. Further, when the handle body is formed into a dogleg shape, the work force can be improved by utilizing a mechanically small force when pressing and cutting.
