DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shovel anchor for a special purpose.

[0002]

2. Description of the Related Art Conventionally, for planting a large tree, as shown in FIGS. 1 and 2 of the accompanying drawings, first, a root pot (5) in which the root of the tree is packed with a rope or the like so as to be easily transported is settled. Therefore, for example, a square pipe is combined with a square pipe or the like to form a square, and the frame body (2) reinforced by crossing the pipe vertically and horizontally is set to have an area where the frame body (2) can be fixed at the bottom of the hole, and the root pot (5) can be implanted. A penetration hole (1) having a depth is excavated, and a stationary anchor (3) is installed from the bottom surface of the hole to the outer periphery of the frame (2) at, for example, 8 equally spaced points, through which the frame (2) is passed. Then, each anchor rod (4) and the frame (2) are connected to each other with a nut, and the frame (2) is strongly fixed on the bottom surface of the hole. Here, the root pot (5) is placed on the frame (2). ) Is placed, and the root basin (5) and the frame (2) are strongly tightened with the tightening rope (6) from a required number of directions to maintain tree independence. It is those that have been.

[0003]

However, since the stationary anchor (3) to be described above is required to have a vertical tensile strength even if it is saturated, it is impossible to use stay anchors for general diagonal tensile strength. It becomes.

[0004] Therefore, a vertical hole was unavoidably made into an earth auger, and a fixed anchor (3), which widened greatly at the bottom of the hole, was used.

[0005] In other words, planting contractors have completely spread the use of power shovels as construction equipment, but earth augers are completely unnecessary equipment. Therefore, if the earth auger is leased each time, the profit base will be greatly deviated. Therefore, the development of anchors that could make full use of power shovels was urgently needed.

[0006]

A power shovel cannot excavate a vertical round hole like an earth auger, but a power shovel can excavate a vertical hole having a rectangular cross section corresponding to a bucket width. Power shovels have a strong ability to pull buckets forward. Collecting the features of the excavator in this way makes it easier than ever.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to FIGS. The perspective view according to FIG. 3 shows an anchor (A) for a shovel, in which a rectangular steel plate is used as a resistance plate (7), the entire length is gently curved, the tip is cut off sharply, and the center of the length is increased. Pressing plate (8) with a height corresponding to the thickness of excavating blade (16) of power shovel (14)
Is firmly fixed around the resistance plate (7), and a reinforcing plate (9) is fixed between the tip and the pressing plate (8) on the length center line of the resistance plate (7), Further, a mounting plate (10) is fixed to the center of the upper side of the pressing plate (8), and the pulling rod (1) is attached to the mounting plate (10).
The shovel anchor (A) is obtained by mounting 1). (12) is a screw which can be machined at the rear end of the pulling rod (11).

As shown in FIG. 4, such a shovel anchor (A) is first formed into a rectangular cross section, and a drilling hole (13) having a predetermined depth is provided.
Excavating the excavator (14) bucket (15)
When a plurality of excavating blades (16) at the distal end of the excavator are inserted into the pressing plate (8) and fixed on the bottom of the hole, and the power shovel (14) is strongly moved forward, the shovel anchor (A)
Means that the tip end up to the pressing plate (8) is easily bitten into the side wall of the unexcavated soil.

[0009] Here, as shown in FIG.
, And carry the excavated soil into the excavation hole (13).
The construction is completed by completely backfilling while pressing with the bucket (15).

[0010]

According to the present invention, a planting contractor can easily install an anchor that requires a vertical tensile strength by using a power shovel owned by the planter. This eliminates the waste of leasing an earth auger and greatly reduces construction costs.

[Brief description of the drawings]

FIG. 1 is a plan view illustrating a conventional technique.

FIG. 2 is a side view of FIG.

FIG. 3 is a perspective view of a shovel anchor (A).

FIG. 4 shows a bucket (1) of a power shovel (14).
It is a side view which shows the state which excavated blade (16) of 5) penetrated into the press plate (8), and the shovel anchor (A) was bitten by the bucket (15) in the unexcavated earth wall.

FIG. 5 is a side view showing a state in which the power shovel (14) has been pulled out and the excavation hole (13) has been backfilled to complete the construction.
