Abstract
Description
[Technical Field]
[0001] The present invention relates to a trap for capturing animals that live in rice paddies. [Background technology]
[0002] Rice paddies are home to agricultural pests such as apple snails (giant apple snails) that harm crop growth and are targeted for capture and extermination.
[0003] Conventional traps are configured so that an attractant for attracting the target to be captured is stored in a rectangular box-shaped container body, and an entry port is formed in the container body to allow the target to enter the interior (see, for example, Patent Document 1).
[0004] The trap is placed on the soil of the paddy field in an area where no crops are growing. [Prior art documents] [Patent documents]
[0005] [Patent Document 1] Utility Model Registration No. 3070748 Summary of the Invention [Problem to be solved by the invention]
[0006] Because rice paddies come in a variety of shapes depending on the land and the crops grown there, the planar shape of the most suitable locations for setting traps (locations where trapping is thought to be most effective) differs from paddy to paddy.
[0007] However, the above-mentioned conventional traps have a fixed rectangular box shape that cannot be deformed, so there is a risk that the traps cannot be installed in an appropriate location for each rice paddy. [Means for solving the problem]
[0008] Therefore, in the present invention of claim 1, a trap for capturing prey living in rice paddies has multiple side walls that are fixed by inserting their lower ends into the soil of the rice paddy, and at least one of the side walls is provided with a trap that the prey can enter but have difficulty escaping, and the left and right ends of all the side walls are connected to each other in a bendable frame shape, making the frame shape deformable when viewed in a plane.
[0009] Furthermore, in the present invention according to claim 2, in the present invention according to claim 1, the side walls are connected to each other with detachable hinges, making it possible to change the number of side walls forming the frame shape.
[0010] Furthermore, in the present invention according to claim 3, in the present invention according to claim 1 or claim 2, a stopper is provided below the trap on the side wall to prevent excessive penetration into the soil of the paddy field. [Effects of the Invention]
[0011] The present invention provides the following effects.
[0012] In other words, in this invention, a trap for capturing prey living in rice paddies has multiple side walls that are fixed by inserting their lower ends into the soil of the rice paddy, and at least one of the side walls is provided with a trap that the prey can enter but have difficulty escaping.The left and right ends of all the side walls are connected to each other in a bendable frame shape, making the frame shape deformable when viewed in a plane.Therefore, the outer shape (frame shape) of the trap can be changed depending on where the trap is installed, and the trap can be installed in a location suitable for each rice paddy.
[0013] In particular, if the side walls are connected with detachable hinges, making it possible to change the number of side walls forming the frame shape, the outer shape (frame shape) and size (area occupied by the frame) of the trap can be changed, making it possible to install the trap in a location that is more suitable for each rice paddy.
[0014] Furthermore, if a stopper is provided below the trap on the side wall to prevent the trap from penetrating too far into the paddy field soil, the stopper can prevent the trap from being buried in the paddy field soil, allowing the trap to remain installed in the paddy field while maintaining its outer shape (frame shape).

DETAILED DESCRIPTION OF THE INVENTION
[0016] Hereinafter, a specific configuration of the trap according to the present invention will be described with reference to the drawings.
[0017] As shown in Figures 1 and 2, trap 1 is used by placing it in a paddy field 2 with its lower end inserted into soil 3 of the paddy field 2. Inside trap 1, attractant 4 is placed to attract the target.
[0018] The trap 1 has a polygonal frame shape (hexagonal in this case) that can be deformed in plan view by connecting the left and right ends of multiple (six in this case) roughly rectangular plate-shaped side walls 5, 6 in a flexible manner via hinges 7. In this trap 1, some (two in this case) of the side walls 5 are detachably provided with traps 8 that the object to be captured can enter but has difficulty escaping, while the remaining (four in this case) side walls 6 are not provided with traps 8.
[0019] As shown in Figures 3 and 4, the side wall 5 in which the trap 8 is provided has an entry opening 9 in the form of a horizontally long rectangular through-hole in the lower central part, and attachment pieces 10, 10 protruding backward in a hook-like shape on each side of the lower half of the entry opening 9 for detachably attaching the trap 8, and a horizontal holding piece 11 protruding backward in a straight line below the entry opening 9 for holding the trap 8 from below.
[0020] The side wall 5 has protruding pieces 12, 12 bent backward at each of the left and right ends, and notches 13, 13 for attaching the hinges 7 formed at intervals above and below at each of the left and right ends, and protrusions 14 protruding backward are formed on the inside of the back surface of each notch 13 for holding the hinges 7 detachably.
[0021] Additionally, the side wall 5 has a plurality of water-passing holes 15 formed in the lower half thereof, which allow water 16 from the paddy field 2 to penetrate into the trap 1 when the trap 1 is placed in the paddy field 2, and the water-soluble attractant 4 can be dissolved by the water 16 that has penetrated into the trap 1.
[0022] Furthermore, the side wall 5 has a stopper 17 that protrudes rearward and is formed in a horizontal, linear shape at a position below the trap 8 (a position below the entry opening 9, attachment piece 10, and holding piece 11) to prevent the lower end of the side wall 5 from penetrating too far into the soil 3 of the paddy field 2 so that the lower end of the side wall 5 will penetrate just enough into the soil 3 of the paddy field 2. By forming the stopper 17 on the side wall 5 at a position below the trap 8 in this way, even if the lower end of the side wall 5 penetrates the soil 3 of the paddy field 2, the stopper 17 acts as a resistance and prevents the side wall 5 from penetrating any further downward, making it possible to prevent the side wall 5 and the trap 8 from becoming buried in the soil 3 of the paddy field 2.
[0023] Furthermore, tape 18 (for example, copper tape that repels apple snails) that repels the target to be captured is attached to the back of the upper end of the side wall 5. This prevents the target that has entered the trap 1 from escaping to the outside through the upper end of the side wall 5.
[0024] As shown in Figures 5 and 6, the side wall 6 on which the trap 8 is not provided has protruding pieces 19, 19 bent backward at each of the left and right ends, and notches 20, 20 for attaching the hinge 7 are formed at each of the left and right ends at intervals above and below, and a protrusion 21 is formed on the inside of the back surface of each notch 20 so as to protrude backward and for holding the hinge 7 detachably.
[0025] Additionally, the side wall 6 has a plurality of water-passing holes 22 formed in the lower half thereof, which allow water 16 from the paddy field 2 to penetrate into the trap 1 when the trap 1 is placed in the paddy field 2.
[0026] Furthermore, the side wall 6 has a stopper 23 that protrudes rearward and is formed in a horizontal, linear shape at a position lower than the trap 8 provided on the side wall 5 (a position lower than the entry opening 9, attachment piece 10, and holding piece 11 of the side wall 5) to prevent the lower end of the side wall 6 from penetrating too far into the soil 3 of the paddy field 2. By forming the stopper 23 at a position lower than the trap 8 provided on the side wall 5 in this way, even if the lower end of the side wall 6 is penetrated into the soil 3 of the paddy field 2, the stopper 23 acts as a resistance and prevents the side wall 6 from being penetrated any further downward, thereby preventing the side wall 6 and the trap 8 from becoming buried in the soil 3 of the paddy field 2.
[0027] Furthermore, tape 24 (for example, copper tape that repels apple snails) that repels the target to be captured is attached to the back of the upper end of the side wall 6. This prevents the target that has entered the trap 1 from escaping to the outside through the upper end of the side wall 6.
[0028] As shown in Figures 7(a) and (b), the hinge 7 is formed by flipping a pair of left and right clips 25, 25 upside down and connecting them to a rotation shaft 26 so that they can rotate freely back and forth, and each clip 25 is formed with a pair of front and rear clamping pieces 27, 28, with the front clamping piece 27 formed linearly in the left-right direction, while the rear clamping piece 28 is formed linearly in the left-right direction and has a claw 29 protruding inward at its tip.
[0029] As shown in Figure 7(c), when the clamping pieces 27, 28 of one clip 25 are inserted from the side of the notch 13(20) formed in the side wall 5(6), the clamping piece 27 on the rear side (shown on the front side in Figures 7(c) and (d)) climbs over the protrusion 14(21) formed in the side wall 5(6), and as shown in Figure 7(d), the claw 29 engages with the protrusion 14(21), and the hinge 7 is detachably attached to the notch 13(20).
[0030] As shown in Figure 8, the trap 8 is attached to the side wall 5 of the trap 1 and has a hollow box-shaped trap body 30 that communicates from the outside (the exterior side of the trap 1) to the inside (the interior side of the trap 1).A rectangular thin plate-shaped blocking body 31 is attached to the upper inside of the trap body 30 via a hinge 32 so that it can be opened and closed freely back and forth.
[0031] The trap body 30 has walls 33 to 36 on the top, bottom, left, and right sides, and has openings at the outer and inner ends. The trap body 30 has the upper wall 33 inclined downward from the outside to the inside, the lower wall 34 inclined upward from the outside to the inside, the left wall 35 inclined rightward from the outside to the inside, and the right wall 36 inclined leftward from the outside to the inside, forming an entrance portion that tapers from the outside (the outside side of the trap 1) to the inside (the inside side of the trap 1).
[0032] In addition, the trap body 30 has a flange-shaped frame 37 formed on the outer periphery of the upper, lower, left, and right walls 33 to 36, and the left and right sides of the frame 37 are fitted into the left and right mounting pieces 10, 10 of the side wall 5, and the lower end of the frame 37 is engaged with the retaining piece 11 of the side wall 5, so that the opening at the outer end of the trap body 30 coincides with the entry port 9 of the side wall 5, allowing it to be attached and detached freely to the side wall 5 of the trap 1.
[0033] In this way, trap 8 blocks the inner opening of trap body 30 with blocking body 31, and the upper wall 33 of trap body 30 is connected to blocking body 31 with a hinge 32, so that an object to be captured, such as an apple snail that enters through entry port 9 in side wall 5 (the outer opening of trap body 30), can push open blocking body 31 and enter the inside of trap 1 (trap body 30).On the other hand, even if an object to be captured that has entered inside trap 1 presses blocking body 31 from the inside to the outside, blocking body 31 abuts against the inner opening of trap body 30, so the object to be captured cannot easily escape from the inside to the outside.
[0034] In addition, the lower side of the tapered entrance portion of the trap 8 (the lower wall 34 of the trap body 30) is inclined upward toward the inside of the trap 1, forming a step between the outside of the trap 8 and the placing surface (soil 3) of the rice paddy 2 outside the trap 1, and also forming a step between the inside of the trap 8 and the placing surface (soil 3) of the rice paddy 2 inside the trap 1.This prevents the targets to be captured that are attracted by the attractant 4 from entering all at once and causing the blocking body 31 to remain open, and also prevents the targets to be captured from escaping from the blocking body 31.
[0035] Furthermore, trap 8 is provided with a repellent by adhering tape 38 (for example, copper tape that repels apple snails) that has a repellent effect on the target to be captured to the outer periphery (here, the lower and left and right walls 34, 35, 36). This allows the repellent to prevent the target from moving along trap 8 once it has entered trap 1, preventing it from escaping to the outside.
[0036] The trap 1 is constructed as described above, and is formed by connecting multiple side walls 5, 6 in a flexible manner to form a frame shape in a plan view.The trap is then fixed (installed) in the rice paddy 2 by inserting the lower ends of the side walls 5, 6 vertically from above to below into the soil 3 at the required position in the rice paddy 2.
[0037] In this trap 1, the six side walls 5, 6 are connected in a flexible manner, so that the trap can be formed into a hexagonal shape in plan view as shown in Figures 1 and 2, or can be transformed into a square shape in plan view as shown in Figure 9. In this way, the trap 1 can easily change its frame shape in plan view.
[0038] Furthermore, in the trap 1, the side walls 5, 6 are connected by detachable hinges 7, so that the trap can be formed into a hexagonal shape in plan view by combining a side wall 5 with a trap 8 and a side wall 6 without a trap 8, as shown in Figures 1 and 2, or can be formed into a square shape in plan view by using only four side walls 5 with traps 8, as shown in Figure 10. In this way, the trap 1 is designed so that the number of side walls 5, 6 that make up the trap 1 can be easily changed. Note that the trap 1 only requires the use of at least one side wall 5 with a trap 8.
[0039] As described above, the trap 1 for capturing prey living in a rice paddy 2 has a plurality of side walls 5, 6 that are fixed by inserting their lower ends into the soil 3 of the rice paddy 2, and at least one of the side walls 5 is provided with a trap 8 that the prey can enter but have difficulty escaping from, and the left and right ends of all the side walls 5, 6 are connected together in a bendable frame shape, so that the frame shape can be deformed when viewed in a plane.
[0040] Therefore, with the trap 1 configured as described above, the outer shape (frame shape) of the trap 1 can be changed depending on the location where the trap 1 is installed, and the trap 1 can be installed in a location suitable for each rice paddy 2.
[0041] The trap 1 is configured such that the side walls 5, 6 are connected to each other by a detachable hinge 7, making it possible to change the number of side walls 5, 6 that form the frame shape.
[0042] Therefore, the trap 1 can change its outer shape (frame shape) and size (frame occupation area), making it possible to install the trap 1 in a location that is more suitable for each rice paddy 2.
[0043] The trap 1 is also provided with stoppers 17, 23 at positions below the trap 8 on the side walls 5, 6 to prevent excessive penetration into the soil 3 of the paddy field 2.
[0044] Therefore, in the trap 1 configured as described above, the stoppers 17, 23 can prevent the trap 1 from being buried in the soil 3 of the rice paddy 2, and the trap 1 can continue to be installed (fixed) in the rice paddy 2 while maintaining its outer shape (frame shape).
[0045] In this way, the trap 1 can be flexibly deformed to adapt to the installation location and can be stably fixed to the installation location, thereby improving the efficiency of capturing the target. [Explanation of symbols]
