Description

[Detailed explanation of the invention] A. Purpose of the invention The invention relates to a tool used in agriculture and gardening to prevent sown seeds and newly sprouted shoots from being eaten by birds.

As the proverb goes, ``Gonbei sows the seeds, the crows pick them,'' and the damage caused by birds to the seeds and young shoots was a headache for those involved. For this reason, farmers stick sticks in the four corners of the field and set them up, spread out the net, and wrap the four corners around the sticks. If it gets wet,
It was not uncommon for the entangled net to slip and fall off the pole, reducing its effectiveness.

The present invention eliminates these deficiencies and makes it possible to easily and reliably stretch the net to a desired height.

B. Structure and effect of the invention In the figure, 1 is a rod-shaped main body, and the tapered head 2 is provided with a cross-shaped slot 3 so that the mesh part of the bird net can be sunk into this groove. There is. The lower end 4 of the rod is sharpened so that it can be easily pierced into the soil. Reference numeral 5 denotes a groove extending in the cross-sectional direction, which is provided on the outer surface of the main body, and its functions and effects will be described later.

FIG. 3 is a perspective view showing an example of use, showing the bird prevention device of FIG. 1 standing on the ground and engaging the net.
The shaded part at the bottom of the main body 1 that is stuck into the ground is the part that is underground. The net can be supported at a desired height by aligning appropriate eyes of the bird-prevention net 8 with the slits 3 on the head of the protruding main body and sinking the net. At the same time, as shown in the figure, the sides are also closed to prevent birds from entering.
6 is a U-shaped flat plate as shown in Fig. 2, whose inner width and inner cross-sectional shape match the groove of the main body, and is engaged by pushing it into the groove from the side of the main body so that it becomes integrated with the main body. It is a stopper that allows you to match. It also has the effect of preventing the unit from falling over. In other words, if you stick the main body alone into the ground, there is a risk that the field soil will be soft and the soil will go deeper than desired, but if this is installed, the flat plate will act as a stopper and the main body will be pushed into the ground as desired. It can support height. Also, there is a fear that the main body will be pulled inward by the weight of the net and fall over or tilt, but this can be prevented with this stopper. Reference numeral 7 denotes a lid that engages with the main body head 2, and is intended to prevent the mesh sunk in the slot 3 from coming off due to some kind of accident. The inside is formed into a conical hole that matches the shape of the main body head 2, and when the two are fitted and pressed, they are strongly engaged.
Of course, it is also possible to maintain the engaged state more reliably by using screws or clicks. The figure shows an example in which knurling is cut on the outer surface to make it easier to pick up.

Figures 4 and 5 show modified examples of the stopper mechanism.
Instead of providing a groove in the main body, a small hole 11 is provided that passes through the main body in the cross-sectional direction, and the legs 13 of the stopper 12 are fitted to engage the two together.

As described above, according to the present invention, bird netting can be easily and reliably installed, harvesting is easy, and it is extremely effective in improving agricultural and horticultural work.
