DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tree planting stabilizing apparatus used to support a tree for a predetermined period after tree planting.

[0002]

2. Description of the Related Art When planting a tree that has grown to some extent, a board-shaped tree planting stabilizer is installed at the bottom of the excavated planting hole so that it can withstand strong winds, etc. And the root pot is tied to a tree stabilizing device, and then the planting hole is filled back.

[0003] As a tree planting stabilizer used in this case,
For example, one described in Japanese Patent Application Laid-Open No. 5-260862 is known. In this method, a total of six bars are combined at predetermined intervals vertically and horizontally at a tree planting site to form a lattice board. Each rod-shaped member is formed by combining two iron pipes. At both ends of the rod-shaped members, fixed rods previously pierced into opposing side walls of the planting hole are connected in an extended manner. (Ie the plantation stabilizer is assembled in the planting hole).

The tree planting stabilizing device described in the above publication is troublesome and difficult in that it must be assembled in a planting hole, and the assembly operation itself is complicated due to the large number of parts. It had a troublesome drawback. Therefore, development of a tree planting stabilizing device is now under development, in which a cross-shaped protruding leg is provided around a central base capable of receiving a tree root pot.

[0005]

When a tree is to be supported by a cross leg, it seems that the longer the length of the leg, the higher the stability of the tree as a whole. Tends to. However, when the legs are lengthened, the mutual distance (linear distance) between the ground plates provided at each of the protruding ends increases. For this reason, instead of increasing the stability in the cross-shaped direction along the legs, a problem occurs in that the stability becomes rather unstable in the bisector direction between the adjacent legs.

The present invention has been made in view of the above circumstances, and provides a tree planting stabilizing apparatus capable of improving the stability of trees as a whole while speeding up and facilitating tree planting operations. The purpose is to do.

[0007]

Means for Solving the Problems In the present invention, the following technical means have been taken in order to achieve the above object. That is, the present invention relates to a seat base formed by a frame capable of receiving a tree root pot, and a plurality of extending legs provided so as to be able to expand and contract outward with respect to the seat base. Body, next to each strut leg 3
Adjacent struts due to the corners of the seating base
Connections projecting outward in the direction of the bisector between the legs
It is characterized by forming a ground auxiliary part .

[0008] The seat base may be provided with an anchor holding portion for guiding the driving of the anchor at the protruding end of the grounding assisting portion. It is preferable that the anchor holding portion is configured such that as the anchor is driven, the lower end of the anchor is inclined and guided in a direction away from the seat body.

[0009]

The ground support portion protrudes outward from the seat base capable of receiving the root pot of the tree. Since this grounding auxiliary portion is arranged between adjacent strut legs provided so as to protrude outward from the seat body, the direction of the bisector between the adjacent strut legs is set. Stability is improved.

[0010] If an anchor holding portion is provided at the protruding end of the grounding auxiliary portion with respect to the seat base, the stability in the bisector direction between the adjacent protruding legs can be further enhanced. it can. In the anchor holding portion, if the anchor to be driven into the anchor holding portion is configured to be inclined so that the lower end portion is moved outward from the seat body, the overall anchor force acting as the entire seat body is further increased. Can be.
