DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual farming tool used for cultivation for crop seed or seedling planting or for excavating root crops.

[0002]

2. Description of the Related Art Conventionally, when excavating soil or excavating agricultural products by hand, hand-operated agricultural tools such as hoes, plows, and shovels have been used.

[0003]

The conventional manual farming tools are:
Effective root group area is 40-50cm like fruit vegetables, leaf vegetables, short root vegetables
Can be plowed and excavated, but the soil quality, especially soil and long root vegetables with high moisture content and deep tillage requires considerable power and labor, and the work efficiency is extremely low. Become.

[0004] Tillage, in which the soil is plowed, inverted, agitated, and crushed, swells and softens the soil to increase the total porosity, and supplies oxygen and nitrogen to the soil to promote the growth of bacteria. This is an operation to give a clustered structure, which promotes germination and rooting of seeds and seedlings, and is essential for the growth of crops. Deep cultivation is desired to enhance these effects.
However, it is not easy for conventional manual farming tools to meet this demand.

[0005]

According to the present invention, a simple improvement is made to these manual farming tools, and the working efficiency is improved by applying the principle of leverage.

[0006] For this purpose, in the present invention, a lever member or a tread plate is attached to an arbitrary position from a blade edge to a blade edge of a hand-operated farming tool such as a hoe, a plow, a shovel or the like comprising a handle portion and a blade portion.

[0007] Further, the mounting position of the tread can be adjusted according to the plowing depth.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the embodiment shown in FIG.

The blade 1 of the plow comprises a plurality of blades, in this embodiment three blades, and a blade edge 1a of each blade.
Through holes 2 are opened at appropriate intervals at the same horizontal height from the edge to the blade edge 1b so that the shaft 3 can be inserted. On the back side of the shaft 3, a columnar lever member 4 is attached in parallel with the shaft, that is, in a horizontal direction. Furthermore, a handle 5 is provided on the blade edge 1b at the upper part of the blade portion 1.
And a swinging arm 6 projecting forward is pivotally mounted on the upper part of the handle so as to be tiltable in the vertical direction.

When the plow of the present invention is used, the position of the through hole into which the shaft 3 is inserted is selected in accordance with the degree of deep tillage of the target crop, and the timber 4 is attached with the inserted shaft to perform plowing. First, the blade tip 1a is inserted into the soil, the plow is laid back, and the soil is excavated using the lever 4 to leverage, and then the rocking arm 6 is moved up and down or back and forth to shake the blade and drop the soil. In addition, excavation of crops can be performed by inserting the cutting edge 1a into the soil and levering the lever 4 to lie backward.

Therefore, it is possible to work with little labor utilizing the principle of leverage, to select the insertion depth of the cutting edge at the position of the lever, and to obtain a uniform deep tillage.

[0012]

[Embodiment 1] A blade 1 of a plow is formed with three blades at intervals, and through holes 2 are formed at the same height in each blade. One shaft 3 longer than the width of the blade portion 1 is inserted into the through hole of each blade of the same height,
Engagement holes 4b provided in engagement portions 4a formed at both ends of the lever member 4 are engaged with ends of the shaft protruding from both sides, and are fixed with fasteners 7 such as wing nuts. In addition, lever material 4
Is fixed so that it can rotate with the shaft.
At the upper end of the upper handle 5, a mounting piece 8 is fixed so as to protrude forward on both sides, and the tip of a swing arm 6 is pivotally mounted on the mounting piece 8.

In this embodiment, the lever is attached to both ends of the shaft. However, the attachment method and the attachment position are not limited to the embodiment. For example, the lever may be attached to the shaft between the blades. Can also.

[0014]

Embodiment 2 FIG. 2 shows a second embodiment.

In this embodiment, a square tread plate 9 is used in place of the lever member of the first embodiment, and a through hole 12 formed in the edge 1b of the blade portion 1 is provided.
The shaft 3 is attached to the shaft 3 inserted through the shaft 3.

The attachment of the tread plate 9 is not limited to the shaft 3 inserted through the blade portion, but a rotary shaft may be fixed to the back side of the blade portion and the shaft may be attached to the shaft. This mounting method is not limited to these as long as the tread plate can rotate with respect to the blade portion.

When cultivating, after inserting the blade into the soil,
The work is performed by placing the worker's feet on the tread plate and laying down the work implement using the rotating shaft as a lever. Therefore, stable work is possible even when the deep tillage is deep.

[0018]

Embodiment 3 FIG. 3 shows still another embodiment of the present invention.

In this embodiment, the blade 1 of the lever 4
The blade 1 is sandwiched from the front and back with a mounting plate 10 and a lever 4 crossing the front surface of the blade, and is fixedly fastened with screws 11 at both ends without using a shaft.

It is advantageous to form a recess in which the mounting plate or the lever member engages on at least one of the front and back sides of the blade so that the holding position does not shift.

According to this embodiment, it can be attached to a ready-made work tool.

[0022]

Since the present invention is constructed as described above, the insertion depth of the cutting edge can be adjusted by adjusting the mounting position of the lever, and the depth of tillage can be made uniform. It will be very easy to use. Further, the shaking operation can be easily performed by attaching the rocking arm, and the worker can perform the shaking operation while standing without bending down, even when the working tool is lying down, so that the work is easy. Furthermore, since the product has a simple structure and is easy to manufacture, a product with low product cost can be provided.
