[0009]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the present invention (how to implement the invention) will be briefly described with reference to the drawings, showing the operational effects thereof.

[0010] The handle 1 is gripped to ground the upper or lower ground contact edge 4 of the shaving portion 3 to the ground a. In this case, the ground contact 4 contacts the ground a at only one point. Hold it at an angle.

While the grounding edge 4 is in point contact with the ground a (soil surface), the shaving portion 3 is pressed firmly against the ground a and inserted, and the locus of movement moves downward as shown in FIG. When the earth is moved toward the near side so as to draw an arc, the soil on the surface of the ground a is dug up by the soil removal unit 3, and the excavated soil moves along the inner surface of the soil removal unit 3, and the soil is removed.
From the upper edge to the excavated surface of the ground a, and as a result, the surface of the ground a is dug back and plowed. This operation is repeated to plow the ground a.

Therefore, in a conventional cultivator such as a hoe or a shovel, the ground a is inserted into the ground when the ground is tilled. Dig up. However, according to the tillage implement of the present invention, as described above, once the grounding edge 4 of the soil removing portion 3 is inserted into the ground and moved as it is to the near side (sequentially). Since the digging can be performed by the operation of (1), the operation can be simplified and performed easily, and the cultivator can be continuously scraped off with extremely high workability and operability.

Since the shaving portion 3 is formed in a thin plate shape, it can be easily inserted into the ground a.
Is changed so that the grounding angle range of the grounding edge 4 is changed by changing the grounding angle of the grounding edge 4 with respect to the ground a. When pressed and inserted into the ground a, the resistance of the grounding edge 4 that is in point contact with the ground a is small,
The soiling part 3 can be easily inserted into the ground a.

According to the second aspect of the present invention, in addition to the functions and effects of the first aspect of the present invention, a curved tip portion 2A of the mounting portion 2 formed into a curved rod shape, and a shaving portion also formed into a curved plate shape are provided. 3 can be very easily formed, and the curved tip portion 2A and the soiling portion 3 which are easily surface-matched and superimposed can be easily attached by appropriate means. It can be provided cheaply.

According to the third aspect of the present invention, in addition to the functions and effects of the second aspect, a wide inner surface portion on the upper edge side or the lower edge side of the inner surface of the curved plate-shaped soiling portion 3 bordering the curved front end portion 2A. The grounding edge 4 on the 3A side is suitable for use as the grounding edge 4 for plowing, and the grounding edge 4 on the opposite narrow inner surface portion 3B bordering the wide inner surface portion 3A and the curved tip portion 2A. Is a configuration suitable for use as the grounding edge 4 for adapting to the ground a.

That is, since the width of the grounding edge 4 on the side of the wide inner surface 3A is large from the grounding edge 4 to the curved tip 2A, the curved tip 2A hinders the insertion of the grounding edge 4 into the ground a. The soil excavated from the ground a gets over the curved tip 2A, so that it is suitable for plowing operation. Further, as shown in FIG. 4, the grounding edge 4 on the narrow inner surface 3B side is lowered. The ground a can be adjusted by touching the ground a toward the ground surface and pulling the ground a toward the front as it is. At this time, the soil accumulated in the narrow inner surface portion 3B above the grounding edge 4 is immediately adjacent to the narrow inner surface portion 3B. Since it is blocked from moving upward by the curved tip portion 2A located above, the soil accumulated in the narrow inner surface portion 3B is easily converted to the ground a, which is a configuration suitable for habituation.

[0017]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Specific embodiments of the present invention will be described with reference to the drawings.

A mounting portion 2 is continuously provided at the tip of the rod-shaped handle 1, and a thin sheet-shaped soiling portion 3 is attached to the tip of the mounting portion 2 so that the plate surface extends in the length direction of the handle 1. It is attached so as to be at right angles or inclined with respect to it.

The mounting portion 2 is formed of a rectangular rod having a length. As shown in FIG. 1, the mounting portion 2 having the length is inclined to the right side of the drawing with respect to the rod-shaped
It protrudes from the distal end, and the middle part of the mounting portion 2 is bent to the left, and the distal bent portion is formed into a curved rod shape whose center is most protruded toward the distal end of the handle 1.

The soiling portion 3 is formed by forming a horizontally long rectangular plate into a curved plate shape with the center thereof being the most convex, and the upper and lower flat edges are grounding edges 4 for grounding to the ground a. In addition, the soiling portion 3 adjusts the degree of curvature to the curved tip 2A of the mounting portion 2.
, And the length in the lateral direction substantially matches the length and width of the curved tip portion 2A.

The attachment structure of the curved tip portion 2A of the mounting portion 2 and the soiling plate 3 is such that the convex curved surface side of the soiling portion 3 faces the outside of the handle 1 in the distal direction, and the inner surface thereof is curved. It abuts on the outer surface of the portion 2A, and is fixed by welding the left and right upper and lower portions of the curved tip portion 2A to the inner surface of the soiling portion 3.

In the present embodiment, the curved tip 2A is overlapped and welded and fixed at a position closer to the upper edge than the intermediate portion of the inner surface of the soiling portion 3. The upper edge portion bordering the curved tip portion 2A is a narrow inner surface portion 3B, and the lower edge portion is a wide inner surface portion 3A.

Next, the operation will be described.

When cultivating the ground a, the gripping handle 1 is gripped and the grounding edge 4 at the lower edge of the shaving portion 3 is grounded to the ground a.
At this time, the grounding edge 4 is inclined and held so as to make point contact with the ground a.

In a state where the grounding edge 4 is in point contact with the ground a (soil surface), the grounding edge 4 is pressed firmly against the ground a and inserted, and the locus of movement moves downward as shown in FIG. When it is moved to the near side so as to draw an arc, the soil on the surface of the ground a is dug up by the shaving unit 3, and the excavated soil moves along the inner surface of the shaving unit 3, and Since it falls on the excavated surface of the ground a from the edge and naturalizes,
As a result, the surface of the ground a is dug up and plowed. This operation is repeated to plow the ground a.

Also, it is possible to cultivate the ground a by scratching the ground a with the ground contact edge 4.

When the ground a is to be used, the soiling portion 3
The grounding edge 4 of the upper edge is grounded to the ground a with the downward direction, and is pulled toward the near side as it is to adapt the ground a.

In the present embodiment, since the configuration is as described above, the following effects are obtained.

The degree of curvature of the shaving portion 3 is determined by the curved tip 2A.
And the curved tip 2A is formed of a square rod, so that the curved tip 2A and the inner surface of the soiling part 3 can be very easily and easily aligned. Since a simple attaching means for simply welding the curved tip portion 2A and the soiling portion 3 which are superposed and superposed is adopted,
Manufacturing can be performed very easily, and an inexpensive product can be provided.

In addition, since the upper and lower four portions of the left and right ends of the curved tip portion 2A are welded to the inner surface of the shaving portion 3,
The soiling portion 3 is stably fixed to the curved tip portion 2A, and the pressing force applied to the grounding edge 4 at the time of work is also excellently applied to the grounding edge 4. .

When cultivating the ground a, if the grounding edge 4 on the side of the wide inner surface 3A is used downward as described in the above operation, the width from the grounding edge 4 to the curved tip 2A is large. When the grounding edge 4 is inserted into the ground a, the curved tip 2A does not easily become an obstacle, so that the ground edge 4 is easily inserted. And moves in the direction of the ground contact edge 4 on the opposite side.
Is less likely to hinder the movement of the soil, thus providing a configuration suitable for plowing action.

When accommodating the ground a, the narrow inner surface 3
When the grounding edge 4 of B is used downward, since the width from the grounding edge 4 to the curved tip 2A is small, the soil accumulated in the narrow inner surface 3B is formed by the curved tip 2A immediately above. Since it is prevented from moving upward, the soil accumulated in the narrow inner surface portion 3B is easily converted to the ground a with the pulling-in operation of the work-in operation, and thus the structure is suitable for the work-in operation.

[0033]

Since the present invention is constructed as described above, the grounding edge is strongly pressed against the ground (soil surface) and inserted. For example, as shown in FIG. 3, the locus of movement draws an arc downward. When moved to the near side, the soil on the ground surface is dug up by the plow, and the excavated soil moves along the inner surface of the plow, and from the upper edge of the plow, Fall naturalization results in the ground surface being dug up and plowed.

Therefore, in a conventional cultivating tool such as a hoe or a shovel, the ground is inserted into the ground when tilling the ground. Dig up. However, according to the tillage implement of the present invention, as described above, a single (series) of inserting the grounding edge of the soil removal part into the ground and moving the same directly to the front side as described above Since the digging can be performed by the operation, the work can be simplified and performed easily accordingly, and the cultivator can be an epoch-making cultivator excellent in workability and operability in which the continuous scraping work can be extremely easily performed.

Further, since the shaving portion is formed in a thin plate shape, it can be easily inserted into the ground, and since the shaving portion is curved, the contact angle of the contact edge with the ground can be changed. The grounding length range of the grounding edge changes, for example, when the grounding edge is tilted and held so that it touches only one point, and in this state, when the shaving part is pressed and inserted into the ground, the contact at this point comes in contact The cultivation implement has excellent practicality, such as low insertion resistance to the ground at the rim and easy insertion of the shaved portion into the ground.

According to the second aspect of the invention, in addition to the functions and effects of the first aspect of the present invention, a curved tip of the mounting portion processed into a curved rod shape and a soiling portion also processed into a curved plate shape are provided. Surface matching can be made very easily, and the curved front end and the soiling portion, which are easily overlapped and overlapped, can be easily attached by appropriate means, so that production is very easy and inexpensive. Can be provided.

According to the third aspect of the present invention, in addition to the function and effect of the second aspect of the present invention, the wide inner surface side of the upper edge side or the lower edge side bordering the curved tip of the inner surface of the curved plate-shaped shaving portion is provided. The grounding edge becomes a structure suitable for use as a grounding edge for plowing, and the grounding edge on the narrow inner surface side opposite to the wide inner surface portion and the curved tip portion as a grounding edge for ground adaptation The configuration is suitable for use.

That is, since the width of the grounding edge on the wide inner surface side is wide from the grounding edge to the curved tip, the curved tip is unlikely to hinder the grounding edge when the grounding edge is inserted into the ground. Since the soil that has been removed passes over the curved tip, the structure is suitable for plowing.
As shown in the figure, the grounding edge of the narrow inner surface side is grounded downward with the ground, and the ground can be adjusted by pulling forward as it is, but at this time, it accumulates in the narrow inner surface above the grounding edge Since the soil is prevented from moving upward by the curved tip located just above this narrow inner surface,
The soil that accumulates in the narrow inner surface is easily naturalized into the ground, which is suitable for the habituation.
