Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 This invention relates to a pile remover that is used in agriculture to remove piles that have been driven into the ground for the purpose of preventing the crop being cultivated from falling or inducing them after the completion of cultivation.

[0002]

[Prior art]

 Conventionally, in the agriculture field, when pulling out a pile driven into the ground for the purpose of preventing the crop from falling or attracting it after the completion of cultivation, the person who intends to pull out has mainly used the power of hands or arms to pull out. .

[0003]

[Problems to be solved by the invention]

 This had the following disadvantages. (B) Since the power of human hands or arms is mainly used, pulling out a large number of piles continuously will cause fatigue to accumulate and reduce work efficiency. (B) Particularly when a strongly driven pile is forcibly pulled out, the pile may be bent or broken. The present invention has been devised to solve the above drawbacks.

[0004]

[Means for Solving the Problems]

 A rotating shaft 4 for rotating the sandwiching plate 3 is provided at one of the surfaces of the sandwiching plate 3 equipped with the moving pulley 2 at a position between the nails 1a and 1b on the back surface of the sandwiching plate 3 equipped with the moving pulley 2. The rotary shaft 4 is supported by a bearing 6 mounted on a slider 5 that moves in the longitudinal direction of the frame 7, and the sandwiching plate 3 has a petal 8 that also moves in the frame 7 in the longitudinal direction, A pile remover characterized by being connected to a moving pulley (2) by a single wire (11) fixed to a plate (9) via a stop pulley (10) fixed to a top plate (9).

[0005]

When the present invention is used, the ground plate 12 of the frame 7 is grounded at the ground of the pile 13 to be pulled out, and the pile 13 protruding above the ground is provided with the claw 1 along the longitudinal direction of the frame 7. a and the claw 1b, and the petal 8 is stepped down by the force of the worker's foot. The force transmitted to the wire 11 is transmitted to the stop block 10, the moving block 2, and the top panel 9. Then, the moving pulley 2 is inevitably pulled up, and the sandwiching plate 3 starts to rotate about the rotating shaft 4 at first, and stops while simultaneously pinching and fixing a part of the pile 13 with the claws 1a and 1b. . When the petal 8 is further stepped down, the sandwiching plate 3 is lifted upward together with the pile 13 while following the movement of the slider 5 supported by the bearing 6, and the pile 13 is pulled out.

[0006]

【Example】

 Hereinafter, embodiments of the present invention will be described. As shown in FIG. 2, the holding plate 3 is provided with a claw 1a and a claw 1b, and the holding plate 3 is turned around a middle position between the claw 1a and the claw 1b, which is a back side of the holding plate 3 equipped with the moving pulley 2 where the claw is attached. It has a rotating shaft 4 to be rotated, and the rotating shaft 4 is supported by a bearing 6 mounted on a slider 5 that moves in the longitudinal direction of the frame 7, and is assembled as shown in FIG.

As shown in FIG. 1, a petal 8 that moves in a longitudinal direction on a concentric axis with a slider 5 in a frame 7 is provided.

Then, a single wire 11 having one end fixed to the top plate 9 is passed through the moving pulley 2 provided on the sandwiching plate 3 and the stop pulley 10 fixed to the top plate 9 in this order. The other end of 11 is connected to petal 8.

When the present invention is used in the above configuration, as shown in FIG. 4, the ground plate 12 of the frame 7 is grounded at the ground of the pile 13 to be pulled out, and is projected to the ground. The stake 13 is inserted between the claws 1a and 1b along the longitudinal direction of the frame 7 and stands up. Then, when the person who operates the petal 8 is stepped down by the force of the foot of the worker, the wire 11 inevitably raises the moving pulley 2 upward. When the pulley 2 is pulled upward, the pinch plate 3 starts to rotate about the rotation shaft 4, the claw 1 a and the claw 1 b pinch the pile 13, and the pinch plate 3 and the pile 13 are fixed and integrated. At the same time, the rotation of the sandwiching plate 3 stops. When the petal 8 is further depressed downward, the sandwiching plate 3 fixed and integrated with the pile 13 is moved upward along the movement of the slider 5 while the rotary shaft 4 is supported by the bearing 6 of the slider 5. At the same time as being lifted, the pile 13 is pulled out by the distance moved by the slider 5 as shown in FIG.

When the force applied to the pedal 8 is released, the sandwiching plate 3 and the pedal 8 are respectively moved by a tension spring 14 having one part fixed to the part of the sandwiching plate 3 and the other fixed to a part of the frame 7. Return to position 4 to prepare for the next work.

[0011]

[Effect of the invention]

 The present invention has the above-described configuration, and can reduce the work load on persons who work in pulling out piles driven into the ground in the agricultural field.
