Description

TECHNICAL FIELD The present invention relates to a post insertion/removal tool for inserting a post of an agricultural pipe house into the soil or extracting the inserted post.

When inserting a conventional post into the ground or extracting an inserted post, there are many small inserting/removing tools that work using the strength of hands and feet. The pillars are deep enough to prevent them from falling over, and require a great deal of force to pull them out. In addition, in the case of a small insertion/removal tool, since the installation part with the support is narrow and small, it may be difficult to be fixed or may slide down from the support, and the insertion of the support is poor. Furthermore, when the post is inserted, the force is concentrated on a part of the insertion/removal tool, so the post is likely to be bent or otherwise damaged. In addition, when inserting the posts, it is necessary to insert and install all the posts at a certain depth in order to secure the stability of the pipe house for agricultural use, but it depends on the intuition of the worker. is the current situation.

Patent Literature 1 discloses a support inserting tool for inserting a support mainly for gardening into the ground or removing the support that has been inserted. However, it is difficult for the elderly and weak people to insert and remove the strut inserter that uses the force of the hands and feet. In addition, when inserting with the force of the foot, a material such as plastic may cause the foot to slip on wet soil, which may result in a lack of safety for the operator. Since the strut insert is installed on a portion of the strut, the strut may be subjected to a very large load and damaged. Furthermore, since the depth adjustment function when inserting the support is insufficient, there is a problem that the work must be redone in order to ensure the stability of the agricultural pipe house.

The post insertion tool as disclosed in Patent Document 1 requires a very large force, so it is difficult to easily insert and remove the post insertion tool using the force of the hands and feet. Also, in slippery soil, it is necessary to add a non-slip function to the post insert. Since the post insertion tool of Patent Document 1 is structured to be supported by the projections of the post, there is a possibility that the post without projections will not be firmly fixed and will rub off. When inserting the strut, it is necessary to keep the depth constant, and there are many issues such as the need for an adjustment function.

The present invention provides a column insert for the purpose of improving the above by providing a cylindrical cover portion that can be freely opened and closed, a footstool that is fixed at right angles to the cover portion, and an adjustment ring that is installed at the lower end of the cylindrical portion. It is in the provision of undressing.

In order to solve the above-mentioned problems, the strut insertion/removal tool of the present invention is composed of an openable and closable cylindrical cover portion 2 for inserting the strut 1, a footstool 3, and an adjustment ring 4, so that the strut 1 can be easily removed. It is characterized by being removable.

An anti-slip member 2c is provided on the inside of the cylindrical cover portion 2, and the anti-slip member 2c can be replaced according to the size of the column 1, and can be replaced periodically as it is a consumable item.

Further, the adjustment ring 4 is located at the lower end of the cylindrical cover portion 2 and can be detachably installed at a desired position so that the support 1 can always be embedded at the same depth.

Further, the footstool 3 fixed to the cylindrical cover portion 2 is provided with a footstool anti-slip member 3a.

According to the aspect of the present invention, since the non-slip member 2c is provided on the cylindrical cover portion 2, the post 1 can be firmly gripped, and there is an effect of avoiding slipping down from the post during work.

In addition, the length of the cylindrical cover portion 2 and the non-slip member 2c prevents the supporting point from being concentrated on one part, thereby preventing damage such as bending or damage to the support. The non-slip member 2c has a size that matches the main support for agricultural use and can be replaced, so it is excellent in versatility.

Further, when the support 1 is inserted, the support can be embedded at a constant depth by attaching a detachable adjustment ring 4 to the support 1 at a desired position. can be installed in

When inserting and removing the column 1, the step reinforcing member 3c and the hammer striking portion reinforcing member 3d allow the user to easily and simply insert and remove the column by selecting a work method such as hitting with a hammer or using the foot or shoulder. can. When stepping on and inserting with a foot, the work can be performed safely without slipping even on soil in rainy weather due to the effect of the anti-slip member 3a. 1 is turned upside down and installed at an arbitrary height on the column 1, and then hit with a hammer or the anti-slip member 3a is put on the shoulder and pulled out with the strength of the foot. can be done.
