The manual operation unit 7 is formed in a circular shape in plan view, and its upper surface is rounded. The elastic member 8 is formed of a coil spring that applies an elastic biasing force in the extending direction, and is attached so as to repel the pressing force applied to the manual operation unit 7 from above. The extruding part 6 is attached to the other end 5b of the connecting member 5 and can reciprocate in the vertical direction inside the (three) tangle members 3.
The weed removal member 15 transmits the pressing force (in series) to the pushing portion 6 through the connecting member 5 by the pressing operation of the manual operation portion 7, and the weed (wound around the entangled member 3) at the pushing portion 6. The configuration is such that Z is pushed away and removed (see FIG. 6 described later). In the weed removal member 15, since the manual operation unit 7 is elastically biased upward by the elastic member 8, when the manual operation unit 7 is pressed from above, the push-out unit 6 is pushed downward, and the manual operation unit 7 is manually operated. When the hand is released from the operation unit 7, the push-out unit 6 is pulled back until it comes into contact with the mounting member 13.

Further, the through-hole 4 is formed in the drawing body 1 over the entire length in the vertical direction, and the connecting member 5 is accommodated in the through-hole 4.
The connecting member 5 is in the shape of an elongated bar, and both ends 5 a and 5 b of the connecting member 5 are projected from the openings at both ends of the through hole 4. The connecting member 5 is slidably inserted into the through hole 4 (in the vertical direction). The connecting member 5 transmits a pressing force (on a straight line) from the manual operation unit 7 to the pushing unit 6 and is interlocked in series.

In the bottom view shown in FIG. 3, the plurality of entanglement members 3 are arranged on an imaginary circle C centered on the axial center point P of the vertical tube 10.
In the illustrated example, three rod-like entanglement members 3 are arranged at an equal pitch around the axial center point P of the vertical tube 10 so that the central angles are uniform (120 °), and are parallel to each other ( It is installed vertically (downward).

The extruding portion 6 has a convex portion 16 that enters the gap 9 between the adjacent entangled members 3 and 3.
The extruded portion 6 is a resin molded product, and in the example shown in the figure, has three convex portions 16 corresponding to the three entangled members 3... . Although not shown in the figure, if there are four entanglement members 3..., The extruded portion 6 is formed in a cross-sectional shape having four convex portions 16. Is preferably formed in a substantially star shape in bottom view having five convex portions 16.

  In the weeding tool of the present invention, in the free state shown in FIG. 1, it is preferable that the length dimension L from the operation portion 7 to the tip of the entanglement member 3 is set to 800 mm to 1100 mm. In other words, the weeding tool of the present invention can be manually rotated by holding the handle portion 2 while holding the handle portion 2 while holding the handle portion 2 while the operator is standing. It is configured.

The use method (action) of the above-described weeding tool of the present invention will be described.
As shown in FIG. 4, the weeding tool of the present invention is pressed against the weed Z from above (by applying force to the handle portion 2), and the entanglement member 3 is inserted vertically to the root depth of the weed Z. At this time, the operator grasps the handle portion 2 in a standing posture, sets the aim so that the axial center L ₁ of the vertical tube 10 catches the center of the weed Z, and inserts it firmly with force. .

Next, as shown in FIG. 5, the handle portion 2 is rotated two to three rounds, and the vertical tube 10 is rotated about the axis L ₁ , so that the root of the weed Z is placed on the entanglement member 3. Wrap.
Thereafter, the weed Z is lifted up by pulling it upward while holding the handle portion 2 and then pulled out. Next, as shown in FIG. F is transmitted through the connecting member 5, and the pushing portion 6 pushes out the weed Z wound around the entangled member 3. At this time, the extruding unit 6 also removes the roots and soil of the weeds Z entangled in the gaps 9 of the entangled members 3 and 3 at the convex part 16 to reliably remove the weeds Z.

  As described above, the weeding tool according to the present invention has the handle portion 2 for manual rotation at the upper end, and a plurality of short entanglement members 3 projecting downward from the lower end so as to be entangled with the handle portion 2. A pull-out body 1 having a vertical tube 10 that is vertically connected to and integrated with a member 3 is provided. A manual operation section 7 disposed near the handle section 2 of the pull-out body 1 and a tangling member 3 are disposed.
