Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a support for securing a net for preventing lodging of grass seedlings to be planted in a paddy field.

Conventionally, in rice fields planted with rushes, poles are erected at appropriate positions within the rice fields, and nets for preventing the rushes from lodging are tied to each pole with hanging cords or the like.

However, it takes a lot of time and labor to erect poles in rice fields, as they are done manually using hanging arrows or cylindrical striking tools, and the work efficiency is low. A device for driving pillars has also been developed, but it has drawbacks such as being expensive.

In order to eliminate the above-mentioned drawbacks, the present invention fixes a support column by protruding arm rods from a base rod that can be easily fitted onto a concrete ridge constructed after preparing a paddy field. A feature of the present invention is that a net for preventing rush lodging can be stretched while easily attaching supports to the net.

Hereinafter, the configuration of the present invention will be explained with reference to embodiment figures.

Two round rods are welded in parallel to form an inverted U-shaped base rod 2 that fits into the concrete ridge 1 of the paddy field,
An arm rod 3 is provided by bending one end of the base rod 2 into an L shape, and a round rod arm 3' is provided obliquely upward from a position near one side of the upper surface of the base rod 2 to form an arm rod. A column 4 is fixed to the tips of the base rods 3 and 3' in parallel with the side surface of the base rod 2 so as to protrude upward, and a leaf spring 5 is attached to the upper position of the inner surface of the base rod 2 on the side of the arm rods 3 and 3'. Together with arm rods 3 and 3' of base rod 2
A reinforcing material 6 is fixed to the opposite corner of the base rod 2, and rods 7 and 7' for steadying are protruded from both sides of the upper part of the base rod 2 near the arm rods 3 and 3' to form a strut 8. It is something. In the figure, 9 indicates a net for preventing rush lodging, and 10 indicates a hanging cord.

Next, the effects of the present invention will be explained with reference to embodiment figures.

The pillars 8 according to the present invention are arranged at appropriate intervals on a concrete ridge 1 of a paddy field where rushes are planted.
While attaching the rush grass lodging prevention net 9 at the upper end of the column 4.
The rush lodging prevention net 9 is stretched while being secured with a hanging cord 10. The support column 8 can be easily installed by simply fitting the inverted U-shaped base rod 2 into the upper part of the concrete ridge 1.
The rods 7 and 7' provided on both sides of the base rod 2 prevent the base rod 2 from tilting or shaking, and the leaf spring 5 provided on the inner surface of the base rod 2 tightly contacts one side wall of the concrete ridge 1 to prevent the base rod 2 from tilting or shaking. This prevents sliding or coming off. Since the arm rods 3 and 3' are provided protruding from the base rod 2 to secure the column 4, the column 4 does not get in the way of workers walking on the top surface of the concrete ridge 1. It has the above-mentioned remarkable effects, such as easy removal of the base rod 2 from the concrete ridge 1.
