Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scoop used for operations such as excavation and dredging.

[0002]

2. Description of the Related Art A conventional scoop of this type is shown in FIG. That is, it is composed of a sword tip 1, a handle 2 and a handle 3, and is used for work such as excavation or dredging.

[0003]

However, in such a conventional technique, when excavating the scoop with a scoop, when the operator scoops up the soil, the operator has only a handle 2 and a handle 3 and is shallow. This is not the case when digging a hole, but even when digging a deep hole, one hand tries to hold the handle 3 at the end of the handle 2 and the other hand as close as possible to the sword tip 1. Then, the upper body of the worker has to take a forward bending posture deeply, and after the motion of throwing away the object to be scooped next, the worker takes a raised posture. As described above, the excavation work involves repeated bending and stretching of the upper body by applying a load to both hands, which poses a problem that it imposes a heavy burden on the waist of the worker.

Further, when excavating a deep and narrow hole or when dredging a drainage basin, the sword tip 1 of the scoop is to be inserted deeply, and the hand of the operator on the ground has a portion close to the sword tip 1. I can't. There is a problem that such a work with a scoop is extremely difficult because a large force is required to act on the tip 1 of the handle 2 by holding the portion far from the tip 1 of the handle.

The present invention has been made in view of such conventional problems, and an object thereof is to provide a scoop which can reduce the burden on the operator and can be adapted to a narrow and deep working place.

The portion 1c is bent so that it is easy to apply a pushing force by putting a worker's foot on it.

The handle 12 is a thin-walled steel pipe, the tip of which is a sword tip 11
It is integrally joined to. The base end portion of the handle 12 is formed in a Y-shape, the handle 13 is inserted across the end portion and fixed by welding, and a triangular space C is formed.

The annular hook 22 is fixed by welding in parallel with the longitudinal direction of the handle 12. The rope 21 is attached to the annular hook 22 at the front end 21a of the handle 12 so that the tip 21a of the rope 21 for operation can be fixed and pulled during excavation to apply force to the tip 11 of the sword. A rope 23 is provided along the middle portion of the rope 21 while being fixed along the triangular space of the base end portion 21b of the rope 21.

The handle 23 is constituted by the knot 24 of the rope 21. The position of the handle 23 is preferably in the central part, but the optimum position differs depending on the individual difference of the worker.

As shown in FIGS. 3-5, the annular hook 22
Is U-shaped and is welded with both legs 22a and 22b abutting on the handle 12. The rope 21 is fastened through the hole of the annular hook 22 by hooking the distal end portion 21 on the leg 22a and then connecting the legs.

Next, the operation will be described.

FIG. 6 shows a pot digging operation. In FIG. 6, when excavating using the scoop 10, the operator holds the handle 13 with both hands and pushes the tip 11 of the sword into the soil,
Put one foot on the shoulder 11c of the sword tip 11 and tip 1 of the sword tip 11
Push 1b into the soil. Next, when a force to push down the handle 13 is applied, the handle 13 is used as a force point, a part of the back of the sword tip 11 is used as a fulcrum, and the sword tip 11 is used as an action point.
The sword tip 11 is raised, the soil on the front surface of the sword tip 11 is cut off from the other, and is scooped on the rake face 11a. All the operations that can be performed by the conventional technique can be performed without a feeling of strangeness.

In FIG. 6, the grip 13 is then gripped by one hand and the grip 23 of the rope 21 is held by the other hand to scoop up the excavated soil. At this time, since the upper body of the worker does not bend forward significantly, the burden on the waist is small. Further, the handle 23 can be surely held with a small grasping force as compared with the case where the rope 21 is directly held, which reduces the burden on the operator.

In FIG. 6, subsequently, the handle 13 is held with one hand.
Grasp and scoop up the scooped soil without changing the grip while holding the handle 23 of the rope 21 with the other hand. At this time as well, the upper body of the worker does not greatly bend forward, so that the waist is less likely to be overloaded. In addition, the elasticity of the rope 21 can be used to give momentum to the sword tip 11 to splash the scooped soil further.

In FIG. 6, as the drilling bottom becomes deeper,
The tip A of the handle 12 is underground, and the worker on the ground is the handle 12
It is in a state where it is not possible to hold the tip A of the. If you try to forcibly hold it, your posture will become unstable and the force will be diminished, and if you had a part that the operator could reach, the force acting on the sword tip would be small, and there would be sufficient force at the point of action. Does not work.

Then, the operator replaces the connecting portion A between the handle 12 and the sword tip 11 with the handle 23 of the rope 21,
I am raising. The rope 21 extends to form a triangle,
The force applied to the tip portion acts on the solidified portion A of the rope 21, and the sword tip 11 that has scooped up the soil can be easily pulled up.

The rope 21 is extended by the pulling force, and there is a degree of freedom in the direction of the pulling force. When the operator pulls up the handle 23 in the upward direction of the right hand with the handle 13 of the left hand as a fulcrum, the moment becomes large, and the handle 23 is pulled up more lightly than in the direct upward direction.

In FIG. 6, subsequently, the scooped soil is splashed without changing the handle. By utilizing the elasticity of the rope 21, the sword tip 11 can be repelled and the scooped soil can be repelled further. There is no waste of labor because it is one continuous operation.

FIG. 7 shows the dredging work of drainage gutters or gutters. In FIG. 7, in the case of the dredging work of a narrow deep hole such as a drainage basin or a gutter, the tip A of the handle 12 is underground, and a worker on the ground cannot hold the tip A of the handle 12. . If you try to forcibly hold it, your posture will become unstable and the force will be diminished, and if you have a part that the operator can reach, the force acting on the sword tip will be small, and there will be no sufficient force at the point of action. Does not work Therefore, the conventional technique is not suitable for such work.

Therefore, the operator replaces the connecting portion A between the handle 12 and the sword tip 11 with the handle 23 of the rope 21,
I am raising. The rope 21 extends to form a triangle,
The force applied to the tip portion acts on the solidified portion A of the rope 21, and the sword tip 11 that has scooped up the soil can be easily pulled up.

The rope 21 is extended by the pulling force, and there is a degree of freedom in the direction of the pulling force. When the operator pulls up the handle 23 in the upward direction of the right hand with the handle 13 of the left hand as a fulcrum, the moment becomes large, and the handle 23 is pulled up more lightly than in the direct upward direction.

In FIG. 7, subsequently, the scooped soil is splashed without changing the handle. By utilizing the elasticity of the rope 21, the sword tip 11 can be repelled and the scooped soil can be repelled further. There is no waste of labor because it is one continuous operation.

8 to 10 show a second embodiment of the present invention. The annular hook 22A is fixed by welding in a direction perpendicular to the longitudinal direction of the handle 12. After passing through the annular hook 22A, the rope 21 is rotated around the rear surface of the connecting portion A of the handle 12 with the sword tip 11 and fixed again through the annular hook 22b. In addition, the rod-shaped member 2 is provided near the center of the rope 21.
3a is provided as a handle 23.

Next, the operation will be described.

The pulling force of the rope 21 is transmitted to the handle 12, and the force applied to the annular hook 22b is reduced. Therefore, it is possible to reduce the size and weight of the annular hook. Handle 23 with a rod-shaped member 23a provided near the center of the rope 21
Prevents slipping between hands and ropes and has less gripping force, reducing the burden on workers.

In the above embodiment, the handle 12 and the sword tip 11 are used.
An annular hook 22 is fixed by welding to a connecting portion A with which the operation rope 21 is fixed to the annular hook 22.
The rope 21 is shown as being fixed at its base end through a rectangular space, but the method of attaching the annular hook 22 and the rope 21 by means other than this is not excluded.

For example, the rope 21 may be directly wound around the connecting portion A between the handle 12 and the sword tip 11 and fixed. At this time, a groove or a protrusion may be provided on the handle 12 as a slip stopper.

Alternatively, the rope 21 may be inserted into the annular hook 22 and folded back so that both ends are aligned and fixed to the base end portion of the handle 12.

The annular hook 22 may be fixed by winding a wire around the handle 12 instead of welding, or by cutting a screw on the leg and passing it through a through hole provided at a predetermined position of the handle 12 with a nut. You may conclude.

In this embodiment, the handle 23a has a wooden or rod shape, but other shapes, sizes, materials, methods for fixing the rope 23, etc. are not excluded.

The knot 24 has a very simple structure and is inexpensive to manufacture. The position can be freely changed according to the individual difference of the worker.

The rope 21 does not have to be one continuous rope, and for example, two ropes having an appropriate length may be tied together by the knot 24.

The handles 23 may be movably attached, or a plurality of handles may be provided in advance.

The sword tip 11, handle 12 and handle 13 may be changed in shape, size and material depending on the purpose of use. For example, the sword tip may have a sharp tip, a round tip, or a straight tip. The handle is made of steel, aluminum,
Wood or synthetic resin may be used.

The handle may be formed by extending the base end portion of the handle 12 as it is, or a rod-shaped member may be fixed to the end portion of the handle 12 in a T-shape.
