Description

[Detailed explanation of the idea] (b) Industrial application fields The present invention relates to a weed extractor.

(b) Conventional technology For example, when trying to remove weeds etc. that are mixed in with the lawn, it is normal to remove them one by one with your fingers.
The main part of the tree is plucked out, but this process is extremely troublesome, and there are other inconveniences such as the stem being torn off in the middle and the roots remaining underground.

For this reason, small tools have come into use that use claw-like or small scoop-like objects to act like a lever to dig up weeds, etc. It was not possible to accurately adapt to differences in pod shape, root tension, etc., and it was not possible to achieve a good weeding result.

(c) Problems to be solved by the invention In view of the above circumstances, the invention proposes a method of lifting the entire grass from below the root while holding the root of the grass to be removed from both sides. In this way, it is an object of the present invention to provide a weed removal tool that can perform weeding with a good finish.

(d) Means for solving the problem The weed extractor of the present invention includes a handle, a vertical frame that protrudes from the tip of the handle and has a piercing blade formed at the tip, and A horizontal frame that is fixed to the middle part and extends toward both sides, and a horizontal frame that extends downward from the front and rear sides of this horizontal frame and has a substantially U-shaped longitudinal section, and is connected to the vertical frame through a through hole in the front and rear direction. A support frame that is slidably fitted, guide holes drilled on both sides of the front plate of this support frame, and horizontal rotation via support shafts on both sides of the horizontal frame. A clipping body that is freely pivoted and extends through the guide hole and onto the stabbing blade, and a spring body that is interposed between the front end of the handle and the rear plate of the support frame. The supporting shafts on both sides are located outside of the guide holes on both sides.

(e) Effect Based on the above configuration, as the vertical frame having the stabbing blade moves back and forth in the front and rear directions with respect to the supporting frame, the pinching bodies on both sides open and close in both directions via the cam mechanism. By pushing down the handle using the support frame as a fulcrum, the stabbing blade and the pincer body are pushed up integrally.

(F) Embodiment Next, an embodiment of the present invention will be explained with reference to the drawings.

Reference numeral 1 denotes a handle, and a vertical frame 2 is protruded from the tip of the handle 1, and a piercing blade 3 is continuously formed at the tip of the vertical frame 2.

Reference numeral 4 denotes a horizontal frame, and this horizontal frame 4 is located and fixed to the upper part of the middle part of the vertical frame 2 so as to penetrate through the vertical frame 2, and extends toward both sides.

Reference numeral 5 denotes a support frame, and the support frame 5 is curved in a substantially U-shape in vertical section, extending from the front side of the horizontal frame 4 through the lower side and the rear side. It is fitted into the vertical frame 2 through a bored through hole 8 so as to be slidable in the front and rear directions.

Further, a pair of horizontally elongated guide holes 9 are bored on both sides of the upper part of the front plate part 6 of the support frame 5.

Reference numeral 10 designates a pair of clipping bodies, and the bases of the clamping bodies 10 on both sides are rotatably supported in the horizontal direction on both sides of the horizontal frame 4 via support shafts 11, and their respective front parts are pass through the guide holes 9 on both sides, and are arranged to extend on both sides above the stabbing blade part 3 in the vertical frame 2.

In this case, the sandwiching bodies 1 on both sides of the horizontal frame 4
The shaft fulcrums of 0, that is, the support shafts 11 on both sides are located outside of the positions where the guide holes 9 on both sides are provided.

That is, the pincers 10 on both sides are disposed in a concave state in which the pincers 10 on both sides approach each other as they move forward, by being penetrated by the guide holes 9 on both sides located inwardly from their pivot points. That's why.

Further, the width of each of the guide holes 9 is set to be slightly larger than the width of each of the sandwich bodies 10.

Reference numeral 12 denotes a coil spring as a spring body, and when the coil spring 12 is wound around the vertical frame 2, it is interposed between the front end of the handle 1 and the rear end of the rear plate of the support frame 5. equipped.

In such a configuration, normally, as shown in FIGS. 1 and 2, the support frame 5 is located at a relatively forward position of the vertical frame 2, and the tips of the sandwich bodies 10 on both sides are opened. in a state.

In use, grip the handle 1, place the bottom of the support frame 5 on the ground in front of the growing grass, and aim the stabbing blade 3 diagonally downward, aiming at the roots of the grass. In this state, the coil spring 12 When the vertical frame 2 is pushed forward and downward through the handle 1 while resisting the spring pressure, the stabbing blade 3 is pierced into the ground and located under the grass roots, and the pincer 10
also moves forward via the horizontal frame 4.

At this time, the sandwich bodies 10 on both sides are moved inward by the cam action while their outer edges are pressed by the outer hole edges of each guide hole 9, as shown in FIGS. 3 to 5. As such, the tip is closed, and the grass roots are held in place.

In this state, by pushing down the handle 1 while using the bottom of the support frame 5 as a fulcrum, the piercing part 3
Then, the tip of the clipper 10 is lifted by the lever action, and the grass is pulled out from the ground.

(g) Effects of the invention According to the invention, while holding the handle, the stabbing blade is pierced diagonally into the ground in front of the grass.
By simply pushing down on the handle, the target grass to be pulled out will be uprooted.
There is no need to get your hands dirty for weeding, etc., it is easy to operate, and weeds can be removed accurately.
Furthermore, a weed removal tool that can be used not only for removing weeds, etc., but also for collecting and thinning seedlings, etc., will be provided.
