Description

Technical Field

[0001] This utility model relates to the field of rice-crab farming technology, and in particular to a multifunctional escape prevention device for rice-crab farming. Background Technology

[0002] Rice-crab farming is an ecological agricultural model that combines rice cultivation with crab farming. In the same paddy field, rice provides crabs with habitat, shade, and food (such as plankton and small insects), while the crabs help with weeding, pest control, soil loosening, and fertilization. Crabs have strong climbing and mobility abilities, and using escape-proof devices can prevent them from escaping the paddy field, reducing the economic losses for farmers.

[0003] In existing technologies, some escape prevention devices typically use bamboo poles as stakes, then attach escape prevention nets to the bamboo poles and place them around the rice-crab farming area to prevent crabs from escaping. However, escape prevention nets that rely solely on bamboo poles inserted into the soil for fixation are susceptible to damage from rain or strong winds. This can cause the bamboo poles to loosen, leading to deformation or even collapse of the escape prevention nets, allowing crabs to escape and causing economic losses and ecological impacts. Therefore, to address these shortcomings, a multi-functional escape prevention device for rice-crab farming has been proposed. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a multi-functional anti-escape device for rice-crab farming. This device aims to improve the problem that anti-escape nets in existing technologies are deformed or even collapse under the influence of rain or strong winds.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional anti-escape device for rice-crab farming, comprising a frame, with multiple mounting piles fixedly connected inside the frame, a baffle plate fixedly connected to the top of each mounting pile, multiple elongated holes on the outside of each mounting pile, a force-bearing rod rotatably connected inside the top of each mounting pile, a rotating block fixedly connected to the bottom of the force-bearing rod, multiple receiving holes on the outside of the rotating block, a tensioning claw rotatably connected to the bottom of each receiving hole, a powerful spring installed inside each receiving hole, the mounting piles being connected to an anti-escape net via a locking assembly, a lead block fixedly connected to the bottom of the anti-escape net, a rice paddy fixedly connected inside the frame, and an inclined anti-escape component fixedly connected inside the top of the frame.

[0006] Furthermore, the external part of the force-bearing rod is rotatably connected to the inside of the baffle, and the external part of the rotating block is rotatably connected to the inside of the bottom end of the mounting pile.

[0007] Furthermore, a rotating disk is fixedly connected to the top of the force-bearing rod, and the outside of the tensioning claw is in contact with the inside of the bottom end of the mounting pile.

[0008] Furthermore, one end of the strong spring is fixedly connected to the inside side of the receiving hole, and the other end of the strong spring is fixedly connected to the outside side of the tensioning claw.

[0009] Furthermore, the outer side of the tensioning claw contacts the inner side of the elongated hole, and the outer bottom end of the mounting pile is slidably connected to the interior of the paddy field.

[0010] Furthermore, the connecting assembly includes multiple screws, with the outer ends of every two screws fixedly connected to the left and right ends of the escape-proof net, and a nut threadedly connected to the outer top end of each screw, the bottom end of which contacts the top end of the baffle.

[0011] Furthermore, the top of the escape-proof net contacts the bottom of the baffle plate, and the bottom of the lead block contacts the top of the paddy field.

[0012] Furthermore, the escape prevention component includes an inclined escape prevention plate, the surface of which is coated with a nylon film coating, and the outside of the inclined escape prevention plate is fixedly connected to the inside of the top of the frame.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the installation pile is driven into the soil, and simultaneously, turning the rotating disc causes the tensioning claw to pop out from the installation pile. This further enhances the grip of the installation pile in the soil, ensuring its stability even in harsh weather conditions. Furthermore, the anti-escape net is firmly connected to the installation pile via screws and nuts, resulting in a tighter and more secure connection. It is less prone to loosening or deformation when exposed to strong winds and rain.

[0015] 2. In this utility model, by tilting the escape-proof plate and applying a nylon film coating on it, the tilted escape-proof plate makes it necessary for the crab to overcome gravity when climbing. Compared with vertical or horizontal escape-proof plates, it is more difficult for the crab to climb upwards. The nylon film coating has a smooth surface, making it difficult for the crab to stick to it, which greatly reduces the possibility of the crab escaping. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 2 to 4 This utility model provides an embodiment of a multi-functional escape-prevention device for rice-crab farming, comprising a frame 1. The frame 1 serves to support and fix all components, providing a stable structural foundation for the entire escape-prevention device. Multiple mounting piles 2 are fixedly connected inside the frame 1. The mounting piles 2 are mainly used to fix the escape-prevention net 13 and enhance its stability in the soil. A baffle 3 is fixedly connected to the top of the mounting pile 2. The baffle 3 prevents the nut 12 from being over-screwed and also limits the position of the escape-prevention net 13. Multiple elongated holes 4 are provided on the outside of the mounting pile 2, providing a channel for the tensioning claw 9 to pop out and restricting its direction of movement. A force-bearing rod 5 is rotatably connected inside the top of the mounting pile 2, which transmits rotational force. A rotating disc 6 is fixedly connected to the top of the force-bearing rod 5, which is convenient for the operator to turn, thereby driving the force-bearing rod 5 to rotate.

[0025] The external rotatable connection of the force-bearing rod 5 is connected to the inside of the baffle 3, ensuring that the force-bearing rod 5 can rotate stably without deviation. A rotating block 7 is fixedly connected to the bottom end of the force-bearing rod 5. The rotating block 7 rotates with the force-bearing rod 5, thereby driving the tensioning claw 9 to move. Multiple receiving holes 8 are provided on the outside of the rotating block 7, providing installation space for the tensioning claw 9 and the strong spring 10. The tensioning claw 9 is rotatably connected to the bottom end of the receiving hole 8. Driven by the rotating block 7, the tensioning claw 9 pops out from the elongated hole 4, contacting the bottom end of the installation pile 2 and the soil, enhancing the grip of the installation pile 2 in the soil. A strong spring 10 is installed inside the receiving hole 8. One end of the strong spring 10 is fixedly connected to one side of the inside of the receiving hole 8, and the other end is fixedly connected to the outside of the tensioning claw 9. The strong spring 10 provides the popping force for the tensioning claw 9 and allows the tensioning claw 9 to reset when needed.

[0026] Reference Figure 1 , Figure 2 and Figure 5 The installation stake 2 is connected to the escape-proof net 13 via a locking assembly. The assembly includes multiple screws 11, with each pair of screws 11 fixedly connected to the left and right ends of the escape-proof net 13. The screws 11 connect the escape-proof net 13 to the installation stake 2. A nut 12 is threaded onto the outer top of each screw 11. The bottom end of the nut 12 contacts the top end of the baffle 3, and the top end of the escape-proof net 13 contacts the bottom end of the baffle 3. Tightening the nut 12 secures the escape-proof net 13 to the installation stake 2. A lead block 14 is fixedly connected to the bottom end of the escape-proof net 13, increasing its weight and making it more stably connected to the paddy field 15.

[0027] The frame 1 is internally fixedly connected to a paddy field 15, which is the rice-crab farming area. The bottom end of the lead block 14 contacts the top end of the paddy field 15, further enhancing the stability of the escape-proof net 13. An inclined escape-proof component is fixedly connected to the inside of the top end of the frame 1. The escape-proof component includes an inclined escape-proof plate 16, the surface of which is coated with a nylon film coating 17. The inclined escape-proof plate 16 is externally fixedly connected to the inside of the top end of the frame 1. The inclined escape-proof plate 16 increases the difficulty for crabs to climb by tilting, and the nylon film coating 17 makes it difficult for crabs to attach to it, thus preventing the crabs from escaping.

[0028] Working principle: First, the installation stake 2 is driven into the soil of the paddy field 15. The outer bottom end of the installation stake 2 slides inside the paddy field 15 until it reaches the appropriate position. At this time, the screws 11 at both ends of the escape-proof net 13 are passed through the baffle plate 3, and then the nuts 12 are screwed on, so that the bottom end of the nut 12 contacts the top end of the baffle plate 3, and the top end of the escape-proof net 13 also contacts the bottom end of the baffle plate 3, thus firmly connecting the escape-proof net 13 to the installation stake 2. In this way, the escape-proof net 13 is not easily loosened or deformed when encountering strong winds and rain.

[0029] Next, the rotating disc 6 is turned, causing the force-bearing rod 5 to rotate. The top of the force-bearing rod 5 is fixedly connected to the rotating disc 6, and its external rotatable connection is inside the baffle 3. The rotating block 7, fixedly connected to the bottom of the force-bearing rod 5, also rotates accordingly. Multiple receiving holes 8 are provided on the outside of the rotating block 7. One end of a powerful spring 10 inside each receiving hole 8 is fixedly connected to one side of the receiving hole 8, and the other end is fixedly connected to the outside of the tensioning claw 9. As the rotating block 7 rotates, the tensioning claw 9 pops out from the elongated hole 4, contacting the bottom of the installation pile 2 and the soil. This further enhances the grip of the installation pile 2 in the soil, ensuring its stability even in harsh weather conditions.

[0030] Meanwhile, the inclined escape-prevention plate 16, fixedly connected inside the top of the frame 1, plays a crucial role. The inclined plate 16 forces crabs to overcome gravity when climbing, making it more difficult for them to climb compared to vertical or horizontal plates. Furthermore, the nylon film coating 17 on the surface of the plate 16 has a smooth surface, making it difficult for crabs to adhere. This significantly reduces the likelihood of crabs escaping. The lead block 14, fixedly connected to the bottom of the escape-prevention net 13, contacts the top of the paddy field 15, further enhancing the stability of the net 13.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
