[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vibrating scoop, and more particularly to a scoop which can be easily pushed into earth and sand without using a pickaxe or the like.

[0002]

2. Description of the Related Art A scoop can be easily used as a tool for manual work, and is widely used for various kinds of work. For example,
When excavating earth and sand, the grip of the handle is held in hand, the blade is pushed into the earth and sand by stepping on the shoulder of the blade, and the blade is used to excavate the earth and sand.

[0003]

However, when the earth and sand is hard, the blade cannot be pushed into the earth and sand even if the shoulder of the blade is strongly stepped on with the foot, and it is necessary to break the earth and sand with a pickaxe in advance. There is a problem that the operation is very complicated.

[0004] In view of the above problems, an object of the present invention is to provide a scoop which can be easily pushed into earth and sand without using a pickaxe or the like.

[0005]

Means for Solving the Problems The inventors of the present invention have conducted intensive research and repeated trial production in order to solve the above-mentioned problems, and found that the blade of a scoop can be relatively easily pushed into soil by vibrating the blade. We have found that we can do this and have completed the present invention.

That is, a vibrating scoop according to the present invention is a scoop in which a blade is attached to a tip portion of a handle, and the shoulder of the blade is stepped on with a foot to push the blade into earth and sand. The vibration unit is provided to transmit vibration to the blade, and the blade vibrates in a state where a pushing force is applied to earth and sand on the blade to push away earth and sand to the surroundings, thereby causing the blade to vibrate. It is characterized in that pushing into earth and sand is assisted.

One of the features of the present invention is that a vibrating portion is provided on a handle,
The point is to make the scoop blade vibrate.
When the blade vibrates in a state where a pushing force is applied to the blade of the scoop, the vibrating blade pushes the earth and sand to the surroundings. As a result, even if the earth and sand is hard, the blade is lightly and smoothly pushed into the earth and sand.

The vibrating scoop according to the present invention has a great effect if it is used for excavating earth and sand, but it can also be applied to snow removal work and the like. Accordingly, the term "earth and sand" in the claims means that the earth and sand, snow, and other objects using scoops are included.

In addition, since the blade of the scoop vibrates, the work can be performed efficiently if it is used for hand-punching of earth and sand or leveling of ready-mixed concrete when burying water and sewage pipes on a road or the like. .

Further, when the blade is formed into a shape similar to a bear's bow, the weeds are shaken by vibration, and the weeds can be pulled out easily and lightly. Therefore, a pulling blade having a plurality of claws formed on a tip side thereof with respect to a blade surface and / or a bear's bow having a plurality of claws is further provided, and the drawing blade or the bow is replaced with a blade and attached to the handle. It is preferable that the object to be pulled out, which is hooked on the pulling blade or the hook of the bow, is shaken by the vibration of the vibrating portion, thereby assisting the pulling out of the object to be pulled out by the pulling blade or the bow.

The structure of the vibrating portion is not particularly limited. However, if the vibrating portion is vibrated in the longitudinal direction of the handle, there is a possibility that the hand holding the handle of the handle may be pushed up. Therefore, it is preferable to vibrate around the axis extending in the longitudinal direction of the handle. That is, the vibrating part is constituted by a housing provided in the middle of the handle and a rotating shaft, a weight and a drive motor built in the housing, and the rotating shaft extends in the longitudinal direction of the handle and rotatably supports, It is preferable that a weight is eccentrically mounted on the rotating shaft, and the rotating shaft is rotated by a drive motor to generate vibration around the rotating shaft.

Further, according to the present invention, in a bear hand having a bow base having a plurality of claws attached to a tip end of a handle, a vibrating portion transmits vibration to the plurality of claws on the handle. Provided so that the pull-out object hooked on the claw is shaken by the vibration of the plurality of claws, thereby assisting the pull-out of the pull-out target object by the claw. Can be provided.

The handle provided with the vibrating part is also new and novel, and such a handle can be used in exchange for an existing scoop or bear hand handle. That is, according to the present invention, a handle attached to hand tools, the tip of which is configured to be able to be fixed to a base of a bear's bow having a scoop blade and a plurality of claws, A hand tool is provided on the way so as to transmit a vibration to hand tools, and the vibration generated by the vibration section assists pushing or pulling by the hand tool. Kinds of patterns can be provided.

[0014] Even in the case of the above-mentioned handle of the vibrating bear and the tool, it is preferable to employ a structure in which the vibrating portion vibrates around the longitudinal axis of the above-mentioned handle.
