Description

The present invention relates in particular to a pole installation device for installing electric fences that prevent animals from entering or escaping.

Electric fences generally involve setting up posts at intervals of 5 to 6 meters and stringing connecting members between the posts in multiple rows, all of which is done manually.
Installing an electric fence requires multiple trips to the same location, which requires a large number of people to do the work, and is therefore very labor-intensive.
For example, it takes five people two hours each to set up a 500m electric fence in an abandoned rice paddy, and it takes five people seven days to set up a 1,500m electric fence in a wild grassland.
As such, the installation of an electric fence requires manpower and effort.
There are concerns that the agricultural workforce will continue to decline in the future, so there is a need for a device that can install electric fences by one person or without human intervention in a labor-saving manner.
For example, Patent Documents 1 to 3 propose electric fences that are designed to improve the ease of installation and transportability of the electric fence itself, or to prevent theft.

JP 2011-223963 A JP 2009-22246 A JP 2008-79521 A

However, none of the patent documents propose a device for installing posts to run an electric fence.

The present invention aims to provide a pole installation device that can install pole-to-pole connection members together with poles.

The following describes the pole installation device according to the first embodiment of the present invention.

FIG. 1 is a conceptual diagram of a pole installation device according to this embodiment as seen from the front, and FIG. 2 is a conceptual diagram of the pole installation device as seen from the rear.
The post installation device according to this embodiment has a base frame 10, a post holding mechanism 20 that holds a plurality of posts 1, a post installation mechanism 30 that installs the posts 1 on the ground, a post connection member holding mechanism 40 that holds the post connection members 2, and a grass cutting mechanism 50. In this embodiment, an electric fence installation device in which the post connection members 2 are overhead wires will be used for explanation, but the post connection members 2 can also be barbed wire, rope, wire, netting, or tape.
The base frame 10 supports a pole holding mechanism 20, a pole installation mechanism 30, an inter-pole connection member holding mechanism 40, and a grass cutting mechanism 50, and can be moved by a traveling mechanism 60.
A pillar installation mechanism 30 is arranged on the rear side of the base frame 10, a pillar connection member holding mechanism 40 is arranged on the front side of the base frame 10, and a pillar holding mechanism 20 is arranged between the pillar installation mechanism 30 and the pillar connection member holding mechanism 40.
In addition, a grass cutting mechanism 50 is disposed on the front side, which is the direction of travel of the base frame 10 .
By arranging the pillar installation mechanism 30 on the rear side of the base frame 10 and the pillar-to-pillar connection member holding mechanism 40 on the front side of the base frame 10, a distance can be secured between the pillar installation mechanism 30 and the pillar-to-pillar connection member holding mechanism 40. This allows the pillar-to-pillar connection member 2 to be smoothly unrolled even if it is displaced downward due to the installation of the pillar 1, and also allows the number of pillars that can be held between the pillar installation mechanism 30 and the pillar-to-pillar connection member holding mechanism 40 to be increased.

The pillar holding mechanism 20 has a guider 21 arranged in the front-to-rear direction of the base frame 10, and this guider 21 holds the pillar 1 in a vertically upright position.
One side of the guider 21 (in front of the base frame 10) is open, and a pillar installation mechanism 30 is disposed on the other side of the guider 21 (in rear of the base frame 10).
The pillars 1 can be loaded into the guider 21 from the front side of the base frame 10. It is preferable that the guider 21 can be loaded with 20 pillars 1, and more preferably, 30 pillars 1.
By opening one side of the guider 21 in this manner and positioning the pillar installation mechanism 30 on the other side of the guider 21, the pillar 1 can be replenished to the pillar holding mechanism 20 without interfering with the installation operation of the pillar 1.

The support post installation mechanism 30 can change its height depending on the length of the support post 1, so that a support post 1 of a length suitable for the target animal can be used.
For example, if the target animal is a wild boar, bear, or civet/raccoon, a post 1 with a length of 1.0 m is suitable; if the target animal is a sheep or cow, a post 1 with a length of 1.5 m is suitable; and if the target animal is a horse, deer, or monkey, a post 1 with a length of 2.0 m is suitable.

The inter-post connection member holding mechanism 40 has a plurality of bobbins 41, a shaft portion 42 that rotatably supports these bobbins 41, and an inter-post connection member holding frame 43 that supports the shaft portion 42. The bobbins 41 used are, for example, 200 m or 400 m long.
The height of the inter-pillar connection member holding mechanism 40 can be changed according to the length of the pillar 1. The height of the inter-pillar connection member holding mechanism 40 can be changed by replacing it with a shaft portion 42 of a different length or by connecting the shaft portion 42 by a joint of multiple members.
The inter-post connection member holding mechanism 40 can change its height depending on the length of the post 1, making it possible to use posts 1 of a length appropriate to the target animal.
The inter-support connection member holding mechanism 40 can change the height of the bobbins 41 and the number of bobbins 41. By changing the height and number of each bobbin 41, the width of the inter-support connection member and the number of stages of the inter-support connection member can be changed according to the target animal.
For example, if the target animal is a "cow", the width of the inter-post connection members is 30 cm and the number of stages of the inter-post connection members is 3; if the target animal is a "sheep", the width of the inter-post connection members from the bottom to the third stage is 15 cm, the width of the inter-post connection members between the third and fourth stages is 20 cm, and the width of the inter-post connection members between the fourth and fifth stages is 25 cm, and the number of stages of the inter-post connection members is 5; if the target animal is a "horse", the width of the inter-post connection members from the bottom to the third stage is 30 cm and the number of stages of the inter-post connection members is 3; if the target animal is a "deer", the width of the inter-post connection members from the bottom to the third stage is 30 cm, the width of the inter-post connection members between the third and fourth stages is 45 cm, and the number of stages of the inter-post connection members is 50 cm. if the target animal is a "wild boar", the width of the inter-post connection member is 20 cm and the number of stages is 3; if the target animal is a "bear", the width of the inter-post connection member is 15 cm and the number of stages is 4; if the target animal is a "civet/raccoon", the width of the inter-post connection member is 10 cm and the number of stages is 4; if the target animal is a "fox/raccoon dog", the width of the inter-post connection member is 15 cm and the number of stages is 3; if the target animal is a "monkey", the width of the inter-post connection member from the bottom to the fourth stage is 15 cm, and the width of the inter-post connection member from the fifth to eighth stages is 20 cm and the number of stages is eight.

It is preferable that the grass-cutting mechanism 50 is a trimmer blade consisting of an upper blade and a lower blade. In this way, by providing the grass-cutting mechanism 50, the support 1 and the support-to-support connection member 2 can be installed while the vehicle is traveling and grass is cut to prevent electric leakage.

The running mechanism 60 is preferably a six-wheel mechanism or a crawler as shown in the figure, but may also be a four-wheel mechanism or an eight-wheel mechanism.

The pole installation device according to this embodiment is preferably equipped with a photographing means 70 for photographing at least the area ahead in the direction of travel and the pole 1 installed on the ground. The photographing means 70 is preferably capable of taking video images, and more preferably capable of taking 360° images in all directions.
In this way, the electric fence installation device of this embodiment is equipped with an imaging means 70 and can further transmit imaging information via a communication means, making it possible to remotely confirm the planned location for installing the post and the condition of the installed post 1.

FIG. 3 is a schematic diagram of a main part showing the operation of supplying posts to a post installation mechanism in the post installation device.
Figure 3(a) shows the orientation of the support 1 when held by the support holding mechanism 20, Figure 3(b) shows the support 1 in the state shown in Figure 3(a) rotated by 45°, and Figure 3(c) shows the support 1 in the state shown in Figure 3(a) rotated by 90°.
The support column installation mechanism 30 has an installation jig 31 .
One surface 1a of the post 1 has a plurality of hooks 3. The hooks 3 are provided parallel to the surface 1a and protrude from the surface 1a.
In the state shown in Fig. 3(a), the hook 3 faces in the front-rear direction, but in the state shown in Fig. 3(c), the hook 3 faces in the left-right direction. Therefore, the inter-post connection member 2 is deeply engaged with the hook 3.

In the pole installation device according to this embodiment, the pole 1 held by the pole holding mechanism 20 is rotated by a predetermined angle and placed on the pole installation mechanism 30.
Therefore, according to this embodiment, by rotating the pillar 1 by a predetermined angle, the direction of the hook 3 for hooking the inter-pillar connection member 2 can be changed, and by changing the direction of the hook 3, the inter-pillar connection member 2 can be securely hooked onto the hook 3. Furthermore, according to this embodiment, since the pillar 1 is rotated by a predetermined angle when being placed in the pillar installation mechanism 30, when held by the pillar holding mechanism 20, the hooks 3 can be arranged so as not to interfere with other pillars 1, and it is possible to increase the number of pillars 1 that can be held in a limited space.

FIG. 4 is a conceptual diagram showing the installation operation of the pole installation mechanism in the pole installation device.
In Figure 4(a), the support 1 is in a state rotated 90° as shown in Figure 3(c), and in this state, the installation jig 31 is moved toward the support 1 (in the direction of the arrow in Figure 4(a)) by the drive mechanism 32.
4B shows a state where the installation jig 31 has started to be lowered. The lowering operation of the installation jig 31 is performed by the drive mechanism 33. As shown in the figure, it is preferable that the drive mechanism 33 itself is also lowered by another drive mechanism (not shown).
FIG. 4C shows a state in which the installation jig 31 has been further lowered from the state shown in FIG. 4B, thereby installing the support 1 on the ground.
4(d) shows a state in which the installation jig 31 is being raised after the installation operation of the pole 1. The installation jig 31 is raised by reversing the rotation direction of the drive mechanism 33. By raising the installation jig 31, the pole 1 is released from the restraint of the installation jig 31, and so leaves the pole installation device while installed on the ground.

In the pillar installation device of this embodiment, the pillars 1 are installed sequentially on the ground while the pillar-to-pillar connection members 2 are fed out from the pillar-to-pillar connection member holding mechanism 40, thereby installing multiple pillars 1 and the pillar-to-pillar connection members 2 between each of the pillars 1.
According to this embodiment, multiple pillars 1 are held, and the pillars 1 are sequentially installed on the ground by the pillar installation mechanism 30 while the pillar-to-pillar connection members 2 are fed out from the pillar-to-pillar connection member holding mechanism 40, so that the pillar-to-pillar connection members 2 can be installed together with the pillars 1.
In this embodiment, some gears are shown as the drive mechanism 33, and the support 1 is installed by a compression mechanism, but the support 1 may also be installed physically by the fall of a hammer or centrifugal force, or even by rotation by a ball screw.
In addition, in this embodiment, some gears are shown as the drive mechanism 33, and the support 1 is installed by a compression mechanism, but the support 1 may also be installed physically by the fall of a hammer or centrifugal force, or even by rotation of a ball screw.

The following describes the pole installation device according to the second embodiment of the present invention.

Fig. 5 is a schematic diagram of the pole installation device according to this embodiment as seen from the front, and Fig. 6 is a schematic diagram of the pole installation device as seen from the rear. Note that the same functional members as those in the pole installation device according to the first embodiment are given the same reference numerals and their explanations will be omitted.
In this embodiment, the inter-pillar connection member 2 is a tape, and the inter-pillar connection member (tape) 2 is used to install the sheet material 2X. The sheet material 2X can be, for example, a resin film or a mesh material.
In this embodiment, a sheet material holding mechanism 80 for holding the sheet material 2X is disposed on the rear side of the base frame 10.
Therefore, the base frame 10 supports the pole holding mechanism 20, the pole installation mechanism 30, the pole-to-pole connection member holding mechanism 40, the grass cutting mechanism 50, and the sheet material holding mechanism 80, and can be moved by the traveling mechanism 60.

In this embodiment as well, one surface 1a of the support pole 1 has a hook 3. In the first embodiment, the hook 3 is used to lock the inter-support connecting member 2, but in this embodiment, it is used to set the support pole 1 on the ground. Details will be described later with reference to FIG.
Although not illustrated, as explained in FIG. 3, in this embodiment too, the support 1 held by the support holding mechanism 20 is rotated by a predetermined angle and placed on the support installation mechanism 30.
Therefore, when placing the support 1 in the support installation mechanism 30, the support 1 is rotated by a predetermined angle, so that when held by the support holding mechanism 20, the hooks 3 can be arranged so as not to interfere with other supports 1, and the number of supports 1 that can be held in a limited space can be increased.

FIG. 7 is a conceptual diagram showing the installation operation of the column installation mechanism in the column installation device.
7, the support 1 according to this embodiment includes a slide mechanism 1x and a leg 1y provided at the tip of the slide mechanism 1x. The slide mechanism 1x is provided with a locking portion 1z.
FIG. 7A shows a state in which the slide mechanism 1 x does not extend from the support column 1 , and in this state, the leg portion 1 y faces in the axial direction of the support column 1 .
From the state shown in FIG. 7A, the installation jig 31 is brought into contact with the locking portion 1z, and the installation jig 31 is lowered.
As shown in FIG. 7B, the slide mechanism 1x moves downward as the installation jig 31 is lowered, and the movement of the slide mechanism 1x causes the ground side ends of the legs 1y to abut against the ground, causing them to expand radially.
FIG. 7C shows a state in which the sliding mechanism 1x has reached the ground. In this state, the legs 1y are spread apart on the ground, thereby setting up the support 1.

In the pillar installation device of this embodiment, the pillars 1 are installed sequentially on the ground while the pillar-to-pillar connection members 2 are fed out from the pillar-to-pillar connection member holding mechanism 40, thereby installing multiple pillars 1 and the pillar-to-pillar connection members 2 between each of the pillars 1.
According to this embodiment, multiple pillars 1 are held, and the pillars 1 are sequentially installed on the ground by the pillar installation mechanism 30 while the pillar-to-pillar connection members 2 are fed out from the pillar-to-pillar connection member holding mechanism 40, so that the pillar-to-pillar connection members 2 can be installed together with the pillars 1.

In the post installation device according to this embodiment, the posts 1 and the post-post connecting members 2 can be installed by repeating the traveling operation and the post installation operation.
In this embodiment, the explanation of the control mechanism is omitted, but the control mechanism controls running and stopping, and the pillar installation operation and stopping, so that the operation can be performed by one person or by remote control.

The pole installation device of the present invention is suitable for electric fences in pastures and for use in pest control. In addition, because it can automatically install the connection members between the poles, it can distinguish between people passing by, making it an effective COVID-19 countermeasure.
