DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weed remover for removing weeds together with their roots and dropping the removed weeds without soiling their hands.

[0002]

2. Description of the Related Art Conventionally, Xucho work has been a method of cutting with a hoe or a sickle by hand or cutting with a brush cutter.
Even though the grass was cut, the main roots remained in the soil and tended to grow again soon. In addition, various devices for weeding the whole root in a standing posture have been proposed.
For example, in the utility model registration No. 3040974, the weeder proposed by the present applicant is provided with a connecting rod movably up and down on a main pipe having a grip on the upper part, and an operation grip connected to an upper part of the connecting rod, 4 at the bottom of the connecting rod
When the two piercing rods are crossed with each other and pivotally connected, and the piercing rod and the main pipe are connected by a link, the operating grip is pulled to open the piercing rod, and the grip is stabbed into the ground, and then pulled up, The stab rod is closed at the same time, and the grass root is pinched by the stab rod to get out of the ground. Then, by pulling the operation grip again, the stab rod is opened, and there is a weeding device that allows the grass to fall.

[0003]

However, in this weeding device, the degree of opening of the piercing rod is adjusted before the piercing of the ground, or the grass is discharged, depending on the condition of the piercing ground and the state of the grass roots. However, it was difficult to make the piercing rod wide open. The present invention solves these problems and, depending on the state of the grass roots, adjusts the opening degree of the tilling pile and then pierces the ground, so that weeds can be more reliably pulled out together with the roots, and grass that has been pulled out can be easily removed. It is an object of the present invention to provide a weeding device that can be discharged and dropped onto the grass.

[0004]

SUMMARY OF THE INVENTION To this end, the present invention provides a main column which moves up and down in an outer tube having an operation lever mounted on an upper portion, and which exposes upper and lower ends of the main column and a handle is provided at an upper end of the main column. Are arranged in such a way that the angle between the tilling piles of each pair is kept substantially constant, and a pair of Each is rotatably crossed and pivotally attached to the lower end of the main pillar, and the base end of the plow and the lower part of the outer pipe are connected by a link.

[0005]

When weeding is performed with a weeder having such a configuration, when the user lifts the weeder by gripping only the handle, the outer tube descends by its own weight, and the distance between the lower end of the main pillar and the lower portion of the outer tube is reduced. , The base end of the plow connected to the lower part of the outer pipe by a link is pushed outward, and the tip of the plow is greatly opened by rotation of the pivot at the lower end of the main pillar. Then, depending on the condition of the weeds to be extracted, the operating lever is appropriately lifted to adjust the opening of the tip of the plow, and then the tip of the plow is pierced into the ground toward the center of the root of the weed. When the handle and operating lever are closed, the tip of the tilling pile closes while pinching the root of the weed.After that, if the operating lever is lifted, the tilling pile can be pulled out while pinching the weed. it can. Then, release the operating lever and lower the outer pipe, and the tip of the plow will open again and release the weeds that have been extracted.

[0006]

An embodiment of the present invention will be described with reference to the accompanying drawings. The outer tube 3 is formed of a hollow cylindrical metal pipe to which an operation lever 4 is mounted so as to protrude in the left-right lateral direction.
An inner tube 5 that moves up and down while being inscribed in the upper part of the outer tube 3 is inserted. Then, an upper portion of the inner tube 5 is exposed from the outer tube 3, and a handle 2 parallel to the operation lever 4 is attached at an upper end thereof. Further, the main column 1 made of a solid rod is connected to the lower portion of the inner tube 5 with a screw 6 and protrudes from the lower portion of the outer tube 3 through the outer tube 3.

As shown in FIG. 3, an upper flat portion 11 and a lower flat portion 12 are formed at the lower end of the main column 1 exposed from the lower end of the outer tube 3 by rotating at right angles to each other. A shaft hole 13 is provided at the center of each flat portion. Then, the metal bar is bent in a U-shape to sharpen the distal end, and the central portion and the proximal end near the proximal end from the bent portion are formed in a flat shape, and the flat portion in the central portion is formed. Shaft hole 14 in the center
Of the four plows 7, 8, 9, 10 provided with a shaft hole 15 at the center of the flat part at the base end, the plow 7 and the plow 8 intersect each other at the flat part at the center. Then, the shaft holes 14 and 13 are pivotally connected to be openable and closable by the pivot 16 with the upper flat portion 11 at the lower end portion of the main pillar 1 interposed therebetween. The shaft holes 14, 13 are intersected with each other and the shaft holes 14, 13 are sandwiched by the lower flat portion 12 at the lower end of the main pillar 1.
Pivotally open and close.

On the other hand, at the lower end of the outer tube 3, the upper flat portion 17, which is orthogonal to two crushed upper and lower halves while leaving a hole through which the main column 1 is inserted at the center, and is divided into two left and right surfaces, and a lower tier. Are formed, and a shaft hole 19 is provided in each of the flat portions on the left and right sides, that is, in the center of four surfaces in total. Further, four links 20 having shaft holes 21 formed at both ends are prepared, and a pair of base ends of a pair of a plow 7 and a plow 8 which are pivotally attached to the upper flat portion 11 at the lower end of the main pillar 1 are provided. The shaft hole 15 in the portion and one shaft hole 21 of the link 20 are rotatably fixed with screws 22 and the other shaft hole 21 of the link 20 and the shaft provided in the upper flat portion 17 at the lower end of the outer tube 3. The hole 19 is rotatably fixed by a screw 23 for connection. Further, the shaft hole 15 of the pair of base ends of the plow 9 and the plow 10, which are pivotally attached to the lower flat portion 12 of the lower end of the main column 1, and one shaft hole 21 of the link 20 are screwed into the The other shaft hole 21 of the link 20 and the shaft hole 19 of the lower flat portion 18 at the lower end of the outer tube 3 are rotatably shaft-fixed by screws 23 and connected.

In the above-described weeder, when the operating lever 4 located directly below the handle 2 is opened and the outer tube 3 descends with respect to the main column 1, the lower end of the outer tube 3 The distance between the lower ends of the main pillars 1 is reduced,
The links 20 pivotally attached to the proximal ends of 8, 9 and 10 are folded so that each of the four plows is open vertically and much wider than in parallel. Then, depending on the condition of the weeds to be extracted, the operating lever 4 is appropriately lifted, the tip of each plow is closed at an arbitrary opening, and then the handle 2 is pushed downward toward the center of the weed root to push the plow underground. Pierce. Then, the operator grips the handle 2 so as to further close the gap between the operation lever 4 and raises the operation lever 4 to open the gap between the lower end of the outer tube 3 and the lower end of the main column 1. , 9, 10 are extended so that the links 20 are pivotally attached to the base ends thereof, and the tips of the four tillage piles are simultaneously closed while sandwiching the roots of the weeds from all sides. If the handle 2 and the operating lever 4 are lifted while being held, the plow is pulled out while holding the weeds. Then, when the operating lever 4 is released and the outer pipe 3 is lowered, the tip of each plow is reopened widely, and the weeds that have been extracted are released.

[0010]

As described above, by opening and closing the space between the handle 2 and the operation lever 4, a plurality of pairs of tillage piles are closed and opened, so that the weeder of the present invention can pinch or discharge weeds. According to the situation of the weeds to be extracted, the degree of opening at the tip of each tilling pile can be adjusted arbitrarily and easily by adjusting the opening of the hand, and the arbitrary degree of opening can be maintained. ,
This can be done by appropriately lifting the operation lever 4 by hand. Then, the operation lever 4 is lowered so that the extracted weeds can be easily discharged and dropped, and when the outer pipe 3 is located at the lowermost position, the gap between the tips of the plows is largely opened. When each stake is pierced into the ground to remove weeds, the operating lever 4 is appropriately lifted by hand, and the opening of the tip of each stake is adjusted and held arbitrarily, thereby increasing the size of the weeds. Can adapt to the growing situation.
Furthermore, after piercing each plow into the ground to remove weeds, and grasping so as to close the gap between the handle 2 and the operating lever 4, the tip of each plow forcibly pushes the root of the weed from all sides. If you try to pull out the weed while lifting the operating lever, the tip of the plow will be pulled down, and the link will try to extend so that it can stand up while firmly holding the weed. Will be overtaken. Then, the extracted grass is easily discharged and dropped by lowering the operation lever 4 and widely opening between the tips of the plows.
