Description

Technical Field

[0001] This utility model relates to the field of crab seedling breeding technology, and in particular to a protective fence for rice paddy crab seedling breeding. Background Technology

[0002] Rice-crab fry farming is an ecological agricultural model that combines rice planting with crab fry cultivation. When the crab fry are active in the rice paddies, they prey on pests (such as rice planthoppers and stem borers) and weeds. At the same time, their excrement can serve as natural fertilizer, providing nutrients for rice growth.

[0003] However, in the existing technology, ordinary fences are not convenient to assemble and disassemble, or they need to be installed or disassembled piece by piece when assembling, or the linkage structure design is complicated, which is prone to jamming and misalignment, and the operation is time-consuming. In addition, gaps are prone to appear between the fence panels, which may result in misalignment, loose stacking, or insufficient structural stability. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing fences are inconvenient to assemble and disassemble, or require installation or disassembly of individual pieces during assembly, and to propose a protective fence for rice paddy crab seedling farming.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a protective fence for rice paddy crab seedling farming, comprising a first column and a second column, a plug-in plate fixedly connected to the side wall of the first column, and a connecting groove opened on one side of the second column, a base plate fixedly connected between the first column and the second column, and a fence mechanism installed above the base plate.

[0006] The enclosure mechanism includes a rotating rod, with multiple rotating sleeves fitted onto the outer surface of the rotating rod. One rotating sleeve is fixedly connected to the outer surface of the rotating rod, and a first movable plate is fixedly connected to the outer surface of one rotating sleeve. Multiple enclosure plates are fixedly connected to the outer surfaces of the remaining multiple rotating sleeves. Push rods are fixedly connected to the outer surfaces of the first movable plate and the enclosure plates. A fixed plate is rotatably connected to one end of the rotating rod, and the fixed plate is fixedly connected to the side wall of the first column.

[0007] Preferably, a mounting bracket is inserted into the inside of the push rod.

[0008] Preferably, one end of the plug-in plate is plugged into the connecting slot, and the side wall of the plug-in plate is provided with multiple plug-in holes.

[0009] Preferably, a fixing block is fixedly connected to the side wall of the second column, and a plug-in rod is inserted into the inner side of the fixing block.

[0010] Preferably, one end of the plug rod is plugged into the plug hole, and a second movable plate is fixedly connected to one end of the plug rod.

[0011] Preferably, a spring is provided on the inner side of the fixing block, and the spring is sleeved on the outer surface of the plug rod.

[0012] Preferably, a limiting plate is fixedly connected to the outer surface of the plug rod, and the spring abuts against the limiting plate.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, multiple enclosure panels and the first movable panel are naturally unfolded or drooped by gravity drive. The enclosure panels unfold sequentially through hinged cooperation with the first movable panel and form a stable stacked structure with the support of the mounting frame. The mounting frame also plays a guiding and limiting role, improving the shielding effect and structural stability. In the storage stage, the first movable panel can be rotated by rotating the rod, so that the enclosure panels are folded sequentially under the structural linkage and mechanical guidance to form a neat and compact state for easy storage and transportation. The push rod provides limiting and guiding functions during the unfolding process to prevent the enclosure panels from shifting or misaligning. The whole process is convenient to operate, the structure is reliable, and the space utilization efficiency is high.

[0015] 2. In this utility model, the quick positioning and stable connection of the structure are achieved through the plug-in cooperation between the plug plate and the connecting groove. It has good guiding and self-positioning characteristics, effectively improving the installation efficiency. It is suitable for the quick installation and removal of protective devices in aquaculture environments. During the connection process, the elastic restoring force provided by the spring drives the limiting plate to move, thereby driving the plug rod to insert into the plug hole to complete the locking. This locking mechanism not only ensures the stability of the structure, but also has anti-loosening performance and can cope with frequent vibration and impact. In order to achieve quick disassembly, the second movable plate can compress the spring and retract the limiting plate, and the plug rod disengages from the plug hole, completing the quick separation of the plug structure. This design takes into account both the stability of the connection and the convenience of disassembly. Attached Figure Description

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides a protective fence for rice paddy crab seedling farming, including a first column 1 and a second column 3. The side wall of the first column 1 is fixedly connected to a plug plate 5, and a connecting groove 6 is opened on one side of the second column 3. A base plate 2 is fixedly connected between the first column 1 and the second column 3, and a fencing mechanism 4 is installed on the top of the base plate 2.

[0024] The enclosure mechanism 4 includes a rotating rod 41, with multiple rotating sleeves 42 sleeved on the outer surface of the rotating rod 41. One of the rotating sleeves 42 is fixedly connected to the outer surface of the rotating rod 41, and a first movable plate 44 is fixedly connected to the outer surface of one of the rotating sleeves 42. Multiple enclosure plates 43 are fixedly connected to the outer surfaces of the other multiple rotating sleeves 42. Push rods 46 are fixedly connected to the outer surfaces of the first movable plate 44 and the enclosure plates 43. A fixed plate 47 is rotatably connected to one end of the rotating rod 41, and the fixed plate 47 is fixedly connected to the side wall of the first column 1.

[0025] The specific settings and functions of this embodiment are described in detail below. During the enclosure operation, the principle of gravity drive is fully utilized, allowing multiple enclosure panels 43 and the first movable plate 44 to naturally droop or unfold without external force intervention. Specifically, when in the unfolded state, multiple enclosure panels 43 unfold sequentially under the action of gravity through hinged engagement with the first movable plate 44, and achieve stable stacking with the structural support provided by the mounting frame 45, thereby forming a continuous enclosure structure with good shielding effect. In this process, the mounting frame 45 not only plays a guiding and limiting role, but also ensures that the enclosure panels 43 are closely arranged during the stacking process, improving the shielding effect and structural integrity of the enclosure.

[0026] When storage and folding are required, simply rotate the rotating rod 41 manually or mechanically. This will cause the rotating sleeve 42 connected to one end of the first movable plate 44 to rotate, thereby driving the first movable plate 44 to move around the axis of rotation. During rotation, the first movable plate 44 applies a pushing force to the adjacent enclosure plate 43 through the mounting bracket 45 connected to one side, causing the enclosure plate 43 to begin to retract in the opposite direction. As the first enclosure plate 43 unfolds, the next enclosure plate 43 it pushes will also fold synchronously under the guidance and pushing action of the mounting bracket 45. This process continues in sequence, and multiple enclosure plates 43 will complete a layered retraction process under structural linkage and mechanical constraints, forming a compact and neat folded state, facilitating storage and transportation.

[0027] Furthermore, multiple push rods 46 located at one end of each enclosure panel 43 work in conjunction with the mounting bracket 45 to provide limiting and guiding support one by one during the unfolding process, ensuring that the enclosure panels 43 unfold along a predetermined trajectory without deviation or misalignment. This step-by-step unfolding and retraction design not only improves the ease of operation and reliability of the enclosure, but also takes into account space utilization efficiency and structural stability.

[0028] Example 2: Figure 2 - Figure 4 As shown, a mounting bracket 45 is inserted into the inner side of the push rod 46. One end of the insertion plate 5 is inserted into the connecting groove 6, and multiple insertion holes 51 are provided on the side wall of the insertion plate 5. A fixing block 7 is fixedly connected to the side wall of the second column 3, and an insertion rod 71 is inserted into the inner side of the fixing block 7. One end of the insertion rod 71 is inserted into the insertion hole 51, and a second movable plate 74 is fixedly connected to one end of the insertion rod 71. A spring 73 is provided inside the fixing block 7, and the spring 73 is sleeved on the outer surface of the insertion rod 71. A limit plate 72 is fixedly connected to the outer surface of the insertion rod 71, and the spring 73 abuts against the limit plate 72.

[0029] The overall effect of this embodiment is that, during assembly, by inserting the plug-in plate 5 into the corresponding connecting slot 6, rapid positioning and stable connection between structures can be achieved. The plug-in mating design between the plug-in plate 5 and the connecting slot 6 provides excellent assembly guidance and self-positioning characteristics, effectively simplifying the overall installation process and improving assembly efficiency. This structure is particularly suitable for the installation of protective devices in aquaculture environments, meeting the needs of high-frequency loading and unloading while ensuring reliable connection and stability between components.

[0030] During the connection process, the limiting plate 72 is moved by the continuous elastic restoring force provided by the spring 73. When the limiting plate 72 is pushed outward under the action of the elastic force, it will simultaneously drive the insertion rod 71 to move in the set direction, so that the insertion rod 71 can be smoothly inserted into the corresponding insertion hole 51, thus completing the position locking. This locking mechanism maintains structural stability while also having good anti-loosening performance, and can effectively cope with frequent vibration or impact loads in the breeding environment.

[0031] To facilitate easy disassembly, a second movable plate 74 is provided. When it is necessary to disengage, pushing the second movable plate 74 directly drives the insertion rod 71 to move, thereby compressing the spring 73 that originally provided elasticity. This causes the limiting plate 72 to retract to the unlocked state, allowing the insertion rod 71 to disengage from the insertion hole 51, achieving rapid separation between the insertion plate 5 and the connecting groove 6. This structural design improves installation convenience while also ensuring flexibility and efficiency in subsequent operations such as maintenance and disassembly.

[0032] The device's usage and working principle are as follows: During enclosure construction, gravity allows multiple enclosure panels 43 and the first movable panel 44 to move. Due to the presence of the mounting frame 45, the multiple enclosure panels 43 and the first movable panel 44 stack together, thus providing a shielding effect. For storage and folding, simply rotate the rotating rod 41, causing the rotating sleeve 42 at one end of the first movable panel 44 to rotate. This allows the mounting frame 45 on one side of the first movable panel 44 to push the enclosure panel 43 to move. At this time, the enclosure panel 43 closest to the first movable panel 44 will begin to move in the opposite direction. This enclosure panel 43 will also push the next enclosure panel 43 to move via the mounting frame 45 on one side, thereby allowing multiple enclosure panels 43 and the first movable panel 44 to fold sequentially for easy storage. Simultaneously, the presence of multiple pushing rods 46 and the mounting frame 45 sequentially restricts the movement of the enclosure panels 43, ensuring that the multiple enclosure panels 43 and the first movable panel 44 function as a barrier after unfolding.

[0033] During assembly, the plug-in plate 5 and the connecting slot 6 can be plugged in for easy assembly, so as to play a protective role during breeding.

[0034] During the connection process, the elasticity of the spring 73 can push the limiting plate 72 to move, causing the plug-in rod 71 to move under the action of the limiting plate 72, thereby plugging into the plug-in hole 51 and completing the connection locking. In addition, when the second movable plate 74 drives the plug-in rod 71 to move, it will compress the spring 73, which will facilitate the separation of the plug-in plate 5 from the connecting groove 6, realizing convenient disassembly and disassembly.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
