Description

Technical Field

[0001] This invention relates to the field of rice paddy crayfish farming technology, specifically to a protective enclosure device for rice paddy crayfish farming. Background Technology

[0002] Rice-crayfish farming is an ecological farming model that "utilizes water resources and yields multiple harvests from a single field." It combines rice paddies with crayfish farming to enhance the biodiversity of farmland ecosystems and increase economic benefits. A common method in rice-crayfish farming is the use of enclosures, typically consisting of a barrier structure vertically inserted around the perimeter of the rice-crayfish pond or pit. This demarcates the crayfish's habitat, ensures sufficient height to prevent them from jumping out or escaping, and helps protect their habitat from escape or predation.

[0003] However, in existing rice paddy crayfish farming, crayfish may escape from the paddy fields, leading to economic losses. Although the introduction of enclosure boards can reduce the escape of crayfish from rice paddies, the enclosure boards still need to be removed during the crayfish harvesting season, and the crayfish need to be caught with fish traps. This not only consumes a lot of manpower, but also reduces the convenience of crayfish farming and catching. Summary of the Invention

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-2 The present invention provides a protective device for rice paddy crayfish farming, comprising: multiple upright plates 1, fixed baffles 10, movable baffles 9 and L-shaped plates 14.

[0030] In this embodiment, as Figure 1 As shown, multiple upright plates 1 are sequentially spliced ​​together on adjacent sides; two fixed baffles 10 are symmetrically installed at the bottom of the upright plate 1, and a movable baffle 9 is installed at the bottom of the upright plate 1 via a pivot. The movable baffle 9 is located on the adjacent side of the two fixed baffles 10, and both the movable baffle 9 and the fixed baffles 10 are bent plates.

[0031] In use, multiple upright plates 1 are spliced ​​together to form a paddy field slope enclosure structure. To facilitate the installation of multiple upright plates 1, the adjacent sides of every two upright plates 1 are connected by plug-in plates 3 without the need for fasteners or threaded connections. The fixed baffle 10 and movable baffle 9 at the bottom of the upright plate 1 are both bent plate structures. The bent parts are used to block crayfish from climbing in the paddy field, effectively preventing crayfish from escaping.

[0032] like Figure 2 and Figure 3 As shown, an L-shaped plate 14 is fixedly connected to the top side of the movable baffle 9. The outer wall of the vertical end of the L-shaped plate 14 is fixedly connected to a ground cage 16 through a fixed plate 17. By rotating the movable baffle 9 clockwise, the L-shaped plate 14 can be rotated downwards into the paddy field. By rotating the movable baffle 9 counterclockwise, the L-shaped plate 14 can be rotated upwards to reset, and the movable baffle 9 can be rearranged with the fixed baffle 10 again.

[0033] In this embodiment, as Figures 3-7As shown, the rear surface of the upright plate 1 has a rectangular opening 11, and two U-shaped plates 6 are symmetrically installed on the front surface of the upright plate 1. The two U-shaped plates 6 are located on both sides of the rectangular opening 11. A first rotating roller 12 and a second rotating roller 23 are rotatably installed on the adjacent side of the two U-shaped plates 6, respectively. The first rotating roller 12 is located at the bottom of the second rotating roller 23. The ends of the first rotating roller 12 and the second rotating roller 23 are connected by a transmission belt 24. The outer wall of the movable baffle 9 and the inner wall of the vertical end of the L-shaped plate 14 are both fixedly connected with fixing rings 15. Ropes 8 are fixedly connected inside the two fixing rings 15. One end of one rope 8 is fixedly connected to the outer wall of the first rotating roller 12, and one end of the other rope 8 is fixedly connected to the outer wall of the second rotating roller 23. The rope 8 fixed to the outer wall of the second rotating roller 23 is fixed in the opposite direction to the rope 8 fixed to the outer wall of the first rotating roller 12.

[0034] In use, the first roller 12 drives the second roller 23 to rotate via the transmission belt 24. When the first roller 12 and the second roller 23 rotate clockwise, the rope 8 on the first roller 12 can lower the L-shaped plate 14, and the rope 8 on the second roller 23 can raise the movable baffle 9, so that the trap 16 enters the paddy field with the lowered L-shaped plate 14, which is convenient for attracting and catching crayfish. When the first roller 12 and the second roller 23 rotate counterclockwise, the rope 8 on the first roller 12 can raise the L-shaped plate 14, and the rope 8 on the second roller 23 can lower the movable baffle 9, so that the movable baffle 9 is rearranged with the fixed baffle 10.

[0035] Furthermore, such as Figure 1 As shown, a shield 7 is installed on the front surface of the upright plate 1. The U-shaped plate 6, the first bevel gear 21 and the second bevel gear 22 are all located inside the shield 7, and the shield 7 serves to cover and protect them. The end of the rope 8 fixed on the first roller 12 can extend outward through the rectangular opening 11 and be fixed in the fixing ring 15 on the L-shaped plate 14.

[0036] It should be noted that, referring to Figure 4 The bottom of the cover 7 is provided with a linear groove 20, and the end of the rope 8 fixed on the second roller 23 can extend outward through the linear groove 20 at the bottom of the cover 7 and be fixed in the fixing ring 15 on the movable baffle 9.

[0037] like Figure 5 As shown, one end of the first roller 12 passes through one of the U-shaped plates 6 and is fixedly connected to a first bevel gear 21. A rocker arm 13 is rotatably mounted on the outer wall of the vertical plate 1. One end of the rocker arm 13 passes through the vertical plate 1 and is fixedly connected to a second bevel gear 22. The first bevel gear 21 and the second bevel gear 22 mesh with each other. (Refer to...) Figure 7By rotating the rocker arm 13, the first bevel gear 21 and the second bevel gear 22 can be driven to mesh with each other, causing the first roller 12 inside the U-shaped plate 6 to rotate. The first roller 12 drives the second roller 23 to rotate through the transmission belt 24.

[0038] like Figure 4 As shown, two sliding grooves 18 are symmetrically provided at the bottom of the horizontal end of the L-shaped plate 14. Two insert plates 19 are symmetrically fixedly connected to the bottom of the ground cage 16. The insert plates 19 are slidably installed inside the sliding grooves 18. The ground cage 16 is fixedly installed in front of the L-shaped plate 14 and can be slid into the sliding grooves 18 through the insert plates 19, so that the ground cage 16 is initially positioned and installed on the L-shaped plate 14, which facilitates the subsequent installation of the fixing plate 17.

[0039] In another embodiment, a C-shaped plate 4 is fixedly connected to one side of one of the upright plates 1. A C-shaped tube 5 is sleeved on the outside of the C-shaped plate 4. An insert plate 3 is fixedly connected to the adjacent side of every two upright plates 1. The adjacent sides of every two upright plates 1 are interlocked by the insert plate 3. The C-shaped tube 5 can be installed vertically on the ground or on the slope of the paddy field. The upright plate 1 with the C-shaped plate 4 installed can be inserted into the C-shaped tube 5 by the C-shaped plate 4. As the first upright plate 1 to be installed, the splicing between every two upright plates 1 is carried out by the interlocking of the insert plate 3.

[0040] like Figure 2 As shown, in order to facilitate the placement of bait into the trap 16 and the removal of lobsters from the trap 16, the top and bottom of the trap 16 are equipped with cage doors that can be opened and closed.

[0041] like Figure 8 and Figure 9 As shown, a limiting plate 26 is fixedly connected to the rear surface of the upright plate 1. The limiting plate 26 has a slot 28. A plug 25 is fixedly connected to the rocker arm 13. A limiting groove 27 is provided on the rod body of the rocker arm 13. The handle part of the rocker arm 13 can slide in the limiting groove 27 on the rod body. When the rocker arm 13 is used, its handle part slides towards the limiting plate 26 through the limiting groove 27. The plug 25 is inserted into the slot 28 on the limiting plate 26 to fix the position of the rocker arm 13 and prevent it from rotating.

[0042] Specifically, the outer wall of the upright plate 1 is provided with an observation port 2, which allows the breeders to easily observe the crayfish farming situation in the rice paddies and feed them through the observation port 2.

[0043] Based on the above technical solution, the working steps of this solution are summarized as follows: When this invention is used, a paddy field slope enclosure structure is formed by splicing multiple upright plates 1 together. In order to facilitate the installation of multiple upright plates 1, the adjacent sides of every two upright plates 1 are connected to each other by plug-in plates 3, without the need for fasteners for threaded connection.

[0044] Both the fixed baffle 10 and the movable baffle 9 at the bottom of the upright plate 1 are bent plate structures. The bent parts prevent crayfish from climbing in the paddy field, effectively preventing crayfish from escaping. An L-shaped plate 14 is fixed to one side of the top of the movable baffle 9. By rotating the movable baffle 9 clockwise, the L-shaped plate 14 can be rotated downwards into the paddy field. By rotating the movable baffle 9 counterclockwise, the L-shaped plate 14 can be rotated upwards to reset, and the movable baffle 9 can be rearranged with the fixed baffle 10.

[0045] A ground cage 16 is installed on one side of the L-shaped plate 14. The ground cage 16 is positioned and installed in the slide groove 18 by the insert plate 19 and then fixed to the outer wall of the vertical end of the L-shaped plate 14 by the fixing plate 17. In this invention, a rocker arm 13 is installed on one side of the vertical plate 1. By rotating the rocker arm 13, the first bevel gear 21 and the second bevel gear 22 can be driven to mesh with each other, so that the first roller 12 inside the U-shaped plate 6 rotates. The first roller 12 drives the second roller 23 to rotate through the transmission belt 24.

[0046] When the first roller 12 and the second roller 23 rotate clockwise, the rope 8 on the first roller 12 can lower the L-shaped plate 14, and the rope 8 on the second roller 23 can raise the movable baffle 9, so that the trap 16 enters the paddy field with the lowered L-shaped plate 14, which facilitates the attraction and capture of crayfish. When the first roller 12 and the second roller 23 rotate counterclockwise, the rope 8 on the first roller 12 can raise the L-shaped plate 14, and the rope 8 on the second roller 23 can lower the movable baffle 9, so that the movable baffle 9 is rearranged with the fixed baffle 10, and the paddy field is enclosed again to prevent the crayfish from escaping.

[0047] In summary, this invention forms a paddy field slope enclosure structure by splicing together multiple upright plates 1. To facilitate the installation of the upright plates 1, the adjacent sides of every two upright plates 1 are interlocked by plug-in plates 3, eliminating the need for threaded connections.

[0048] In this invention, both the fixed baffle 10 and the movable baffle 9 adopt a bent plate structure to prevent crayfish from climbing and escaping. An L-shaped plate 14 is fixed on one side of the top of the movable baffle 9, and a trap 16 is installed on one side of the L-shaped plate 14. By rotating the L-shaped plate 14, the trap 16 can be allowed to enter the paddy field to trap crayfish, which facilitates crayfish harvesting and eliminates the need to remove the upright plate 1.

[0049] Furthermore, by rotating the rocker arm 13, the first rotating roller 12 and the second rotating roller 23 can be driven to rotate, thereby controlling the rotation of the L-shaped plate 14 and the movable baffle 9, thus controlling the position of the movable baffle 9 and the L-shaped plate 14, realizing the switching between the protection and capture states of lobsters during the breeding process, and improving the convenience of breeding.

[0050] All parts not described in this invention are the same as or can be implemented using existing technology. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
