Description

Technical Field

[0001] This invention relates to the field of animal husbandry technology, specifically to a rice-frog farming system. Background Technology

[0002] Rice-frog farming, also known as "rice-frog symbiosis" or "rice-frog co-cultivation," is an ecological circular agriculture model that combines rice cultivation with frog (mainly black-spotted frog) breeding. This model achieves a win-win situation for both ecological and economic benefits by "using frogs to protect rice and using rice to raise frogs."

[0003] In existing technologies, rice-frog farming is carried out artificially. When feeding, it is generally done at fixed points, times, and quantities. Before the rice rows close, the field has a wide field of vision, making this concentrated feeding method suitable. However, after the rice rows close, the rice frogs are scattered, visibility is poor, and they easily miss feeding spots. Furthermore, concentrated feeding is not conducive to weaker frogs eating. When harvesting frogs manually, traps are typically used, which is inefficient. Manual harvesting is even less efficient, and personnel entering the rice paddy can negatively impact rice seedling growth. Additionally, after the rice rows close, the dense rice seedlings and the large number of rice frogs create poor air circulation within the paddy. The presence of dew further increases humidity, and the lack of ventilation creates a poor growing environment for both rice seedlings and rice frogs, making them susceptible to disease. Summary of the Invention

[0004] The purpose of this invention is to develop a rice-frog farming system that involves scattering feed on rice frogs, driving them away for capture, improving air circulation within the paddy field, and shaking off dew from rice seedlings to prevent excessive humidity in the paddy field.

[0018] Optionally, the track assembly includes multiple sequentially movably connected support plates. The support plates have an isosceles trapezoidal cross-section with rounded corners. The wider end of each support plate faces upward. Multiple forks are provided at the bottom of each support plate. The moving assembly includes a slide seat slidably fitted onto the support plate. The inner wall shape of the slide seat is adapted to the top and sides of the support plate. Two pulleys arranged vertically are rotatably provided on the two inner side walls of the slide seat. Wheel grooves adapted to the positions of the pulleys are provided on the two side walls of the support plate. The pulleys roll within the wheel grooves. The bottom of the wheel grooves is arc-shaped. The height of the wheel grooves is longer than the outer diameter of the pulleys. The driving assembly includes a motor located at the top of the slide seat. A transmission mechanism connecting the motor and some of the pulleys is provided inside the slide seat.

[0019] The bottom of the slide is provided with a support rod, and the support rod is provided with a first proximity switch. At the corresponding position on the bottom of the side wall of the support plate, there are multiple position correction blocks that cooperate with the first proximity switch. The multiple position correction blocks are arranged at equal intervals in the direction of the pull rope. The position correction blocks are located on the side of the trajectory of the first proximity switch as it moves with the slide. The position correction blocks on the support plates on both sides of the paddy field area are positioned correspondingly, and they are grouped in pairs. The two position correction blocks in the same group are on a straight line perpendicular to the direction of the pull rope.

[0020] Optionally, one of the moving components is hinged to an adjustment seat with a vertically rotating shaft. The moving component is equipped with a first servo motor that drives the adjustment seat to rotate. The adjustment seat is equipped with a support. A winding reel for winding the pull rope is rotatably mounted on the support, and a second servo motor that drives the winding reel is also mounted on the support. A vertical storage tray is provided on the adjustment seat on the side of the winding reel away from the support. The storage tray has a storage groove with a slot at the top of the storage tray forming a spiral trajectory. A storage rack is connected to the top slot of the storage tray. The storage rack has a sliding groove that communicates and cooperates with the storage groove. The sliding groove and the storage groove cooperate with the hanging rope. The storage rack is flipped and bent directly below the pull rope on the winding reel away from the track assembly and then enters the top slot of the storage tray.

[0021] Optionally, the adjusting seat is provided with a first monitoring component that cooperates with the first servo motor to monitor the perpendicularity of the pull rope and the winding reel. The first monitoring component includes a bracket located above the winding reel, a downward-facing smart camera on the bracket, and a marker parallel to the winding reel on the bracket. The pull rope and the marker appear in the image captured by the smart camera. The first servo motor drives the adjusting seat to rotate so that the pull rope remains perpendicular to the marker.

[0022] Optionally, a second monitoring component is provided on the support on the side of the winding reel away from the adjusting seat, which cooperates with the second servo motor to monitor the tension or slack of the pull rope. The second monitoring component includes a winding roller rotatably mounted on the support, the winding roller being parallel to the winding reel and having a height higher than the winding reel. The pull rope is wound around the upper part of the winding roller and then wound into the winding reel from above. A vertical slide rail is provided on the support on the side of the winding roller away from the winding reel, and a slider is slidably mounted in the slide rail. A sensor for monitoring the position of the slider is provided in the slide rail. Two rotating rods parallel to the winding roller are rotatably mounted on the slider, and the pull rope passes between the two rotating rods. The second servo motor controls the winding reel to wind and unwind the pull rope so that the slider is within a set height range in the slide rail.

[0023] Optionally, the storage rack is strip-shaped and includes a flip section and a curved section connected in sequence. The curved section is connected to the top slot of the storage tray. The curved section is coplanar with the storage tray. The trajectory of the curved section is adapted to the trajectory of the pull rope entering the winding reel. The end of the flip section away from the curved section is directly below the trajectory of the pull rope and is arranged horizontally. Both the inner wall of the slide groove and the inner wall of the storage groove are provided with a layer of polytetrafluoroethylene material.

[0024] The sliding groove of the flip section of the storage rack is provided with two vertical guide plates. The guide plate includes a straight section and an inclined section. The straight section is parallel to the pull rope and is connected to the flip section of the storage rack. The inclined section is connected to the end of the straight section away from the storage rack. The free end of the inclined section is inclined outward. The inclined sections of the two guide plates form an flared structure in the shape of an isosceles trapezoid.

[0025] The suspension rope is equipped with a rope buckle that mates with the sliding groove and the storage groove. The rope buckle is movably engaged with the suspension rope. The portion between the rope buckle and the bottom end of the suspension rope slides on the storage rack and the storage tray. The storage rack extends from the end connected to the guide plate of the flip section towards the storage tray. The thickness of the storage rack gradually increases until it matches the distance between the rope buckle on the suspension rope and the bottom end of the suspension rope. The thickness of the storage tray also matches the distance between the rope buckle on the suspension rope and the bottom end of the suspension rope. A second proximity switch is provided on the threaded electrical connector at the bottom end of the suspension rope.

[0026] The beneficial effects of this invention are:

[0027] The invention features a pull rope that moves within the paddy field. The length of the pull rope can be adjusted according to the edge trajectory of the paddy field, making the system suitable for irregularly shaped paddy fields. This prevents the pull rope from breaking or falling to the ground. The winding angle of the pull rope can be adjusted to prevent it from falling off during winding. Different working components on the pull rope can realize automatic feeding of rice frogs, automatic and efficient frog harvesting, and automatic paddy field care. During the automatic adjustment of the pull rope to the shape of the paddy field, the working components can be automatically stored.

[0028] The feeding components combine centralized feeding with uniform feeding. During the rice-frog growth period, feed is evenly scattered in the paddy field, especially during the rice canopy closure period, so that all rice-frogs can eat. This avoids the situation where large, aggressive rice-frogs occupy advantageous positions and eat their fill while small, weak rice-frogs are hindered from eating, thus avoiding large differences in the size of rice-frogs. The feeding components can automatically stop scattering feed after being stored, thus avoiding feed waste.

[0029] The frog-catching component is set up so that the rice frogs are gradually driven into the rice field area where the catching cage is placed. The rice frog catching process is automated and efficient. The rope moves slowly, the sound and light stimulation signals of the frog-catching component are intermittent, and the rice frogs are domesticated by the working mode of the feeding and care components during their growth period, so that the rice frogs are not easily stressed. The frog-catching component moves to cover the entire rice field. After driving the rice frogs away, the number of rice frogs remaining in the rice field is low, and the rice frog catching operation can be basically completed in one go.

[0030] The nursing components allow the rice seedlings to be moved during the rice canopy closure period, shaking off the dew and reducing humidity in the paddy field. Moving the seedlings also increases air circulation in the field, reducing the probability of disease occurrence and providing a good growth environment for rice frogs and rice seedlings.

[0047] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0048] The following disclosure provides many different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, the present invention provides examples of various specific processes and materials, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0049] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0050] Example 1

[0051] like Figure 1 As shown, this embodiment discloses a rice-frog farming system, including track components arranged along the opposite two edges of a rice paddy area. The rice paddy area is surrounded by a fence, and the track components are located inside the fence, with the two track components arranged in parallel.

[0052] like Figure 1 and Figure 5 As shown, a movable component is slidably mounted on the track assembly, and a drive component is mounted on the movable component to drive the movable component to slide on the track assembly. A pull rope 4 is connected between the movable components on the two track assemblies. Multiple hanging ropes 22 are evenly spaced on the pull rope 4, and working components are movably connected to the hanging ropes 22. Different types of working components can be used to perform tasks such as feeding, frog harvesting, and rice paddy care.

[0053] like Figure 1 , Figure 2 and Figure 4As shown, the track assembly includes multiple sequentially movably connected support plates 1. The support plate 1 has an isosceles trapezoidal cross-section with rounded corners. The wider end of the support plate 1 faces upwards. A rubber elastic layer 19 is provided on the sidewalls of adjacent support plates 1. The elastic layer 19 prevents rigid contact between the support plates 1 and fills any gaps between them as much as possible. Two connecting slots 18 are provided at both the top and bottom ends of each support plate 1. Screw holes are provided in the connecting slots 18, and bolts 21 are threaded into these holes. When two support plates 1 are connected, the two connecting slots 18 at their top and corresponding top ends are positioned opposite each other. Pull plates 20 are provided within the two connecting slots 18. Strip-shaped grooves are provided on the pull plates 20, with a width sufficient for the bolt shank to pass through, but preventing the bolt head from passing through. When the side walls of the two support plates 1 are fitted together, the distance between the screw holes of the two connecting grooves 18 is less than the length of the strip groove, and the size of the connecting groove 18 is larger than that of the pull plate 20. The pull plate 20 has a certain range of swing and movement within the connecting groove 18. After the pull plate 20 and the bolt 21 are fixed to the connecting groove 18, the top of the bolt 21 will not protrude above the top of the connecting groove 18 to avoid affecting the movement of the moving component. Through the cooperation of the connecting groove 18, the pull plate 20, and the bolt 21, a certain angle of tilt can be achieved between the two adjacent support plates 1.

[0054] like Figure 2 As shown, the bottom of the support plate 1 is equipped with multiple forks 5, which are used to insert into the soil at the edge of the paddy field area to fix the support plate 1. The bottom of the fork 5 includes a vertical rod and diagonal rods on both sides of the vertical rod. The bottom of both the diagonal rods and the vertical rod is equipped with vertically inserted rods. After the fork 5 is inserted into the soil, the two diagonal rods play a role in strengthening the stability of the fork 5 and preventing the fork 5 from tilting.

[0055] like Figure 3 As shown, the movable component includes a slide block 2 that is slidably fitted onto the support plate 1. The inner wall shape of the slide block 2 is adapted to the top and sides of the support plate 1. Two pulleys 9 are rotatably arranged vertically on the two inner side walls of the slide block 2. The two side walls of the support plate 1 are respectively provided with wheel grooves 8 that are adapted to the positions of the pulleys 9. The wheel grooves 8 also penetrate the elastic layers 19 on the two connecting surfaces of the support plate 1. The pulleys 9 roll in the wheel grooves 8. The bottom of the wheel grooves 8 is arc-shaped. The height of the wheel grooves 8 is longer than the outer diameter of the pulleys 9. That is, there is a certain distance between the top of the pulleys 9 and the top of the wheel grooves 8. The pulleys 9 and the bottom of the wheel grooves 8 roll in contact.

[0056] like Figure 2As shown, the drive assembly includes a first transmission rod 12 rotatably mounted in the top of the slide block 2. The first transmission rod 12 is horizontally arranged, and its two ends are coaxially connected to a first bevel gear 13. Second transmission rods 15 are rotatably mounted in both sides of the slide block 2. A second bevel gear 14, coaxially connected to the top of each second transmission rod 15 and meshing with the corresponding end of the first bevel gear 13, is connected to the bottom of each second transmission rod 15. A fourth bevel gear 17, coaxially connected to the inner end of a pulley 9 on the upper sidewall of the slide block 2, meshes with the third bevel gear 16. A motor 3 is mounted on the top of the slide block 2, and a worm gear 10 rotatably connected to the motor 3 is mounted inside the top of the slide block 2. A worm wheel 11, meshing with the worm gear 10, is coaxially connected to the corresponding position of the first transmission rod 12.

[0057] like Figure 2 As shown, when the motor 3 operates, it drives the first transmission rod 12 through the transmission of the worm gear 10 and the worm wheel 11, drives the second transmission rod 15 through the meshing of the first bevel gear 13 and the second bevel gear 14, and drives the pulley 9 to rotate through the meshing of the third bevel gear 16 and the fourth bevel gear 17. The pulley 9 rolls in the wheel groove 8, causing the slide block 2 to slide on the track assembly constructed by multiple support plates 1.

[0058] like Figure 2 As shown, the bottom of the slide block 2 is equipped with a support rod, and a first proximity switch 6 is mounted on the support rod. At corresponding positions on the bottom of the side wall of the support plate 1, multiple position correction blocks 7 are provided to cooperate with the first proximity switch 6. These position correction blocks 7 are arranged at equal intervals along the direction of travel of the pull rope 4. The position correction blocks 7 are located on the side of the trajectory of the first proximity switch 6 as it moves with the slide block 2. When the first proximity switch 6 passes the position correction block 7, it is triggered. The position correction blocks 7 on both sides of the support plate 1 in the paddy field area are positioned correspondingly, forming pairs. The two position correction blocks 7 in the same pair are on a straight line perpendicular to the direction of travel of the pull rope 4.

[0059] When the two slide blocks 2 move synchronously, they drive the pull rope 4 to move in a state perpendicular to the direction of travel. After the two slide blocks 2 move to the two position correction blocks 7 of the same group, they continue to move. That is, the slide block 2 that reaches the position correction block 7 first stops. When the other slide block 2 also reaches the position correction block 7 of the same group, the two slide blocks 2 move synchronously again. Through this segmented operation mode, the pull rope 4 is not perpendicular to the direction of travel due to the inevitable speed difference between the two slide blocks 2. This also avoids the pull rope 4 being pulled due to displacement error of the slide blocks 2 at both ends of the pull rope 4. The movement of the slide blocks 2 is segmented by multiple position correction blocks 7. The running error of the two slide blocks 2 in each segment is not enough to cause a large displacement difference in the direction of travel of the pull rope 4. The running error of each segment is corrected at the position correction block 7 of that segment, avoiding the accumulation of running error and the gradual increase of the displacement difference of the two slide blocks 2 in the direction of travel of the pull rope 4.

[0060] The height of the pull rope 4 is adapted to the height of the rice in the paddy field, meaning that the pull rope 4 is basically at the top of the rice during movement, preventing it from knocking over or damaging the rice. The height of the pull rope 4 can be adjusted by the insertion depth of the fork 5 at the bottom of the support plate 1. Correspondingly, the length of the fork 5 can also be adjusted by replacement. The fork 5 is detachably connected to the support plate 1 to allow for replacement with forks 5 of different lengths. The height of the pull rope 4 can also be achieved by adjusting the tension of the pull rope 4. This method is suitable for situations where the edge of the paddy field is relatively high. When the support plate 1 is inserted into the edge of the field, the height of the sliding seat 2 is much higher than the top of the rice. By adjusting the tension of the pull rope 4, it bends and droops under its own weight, as well as the weight of the suspension rope 22 and the working components, so that the part inside the paddy field is at the top of the rice.

[0061] like Figures 6-8 As shown, the working components include three types: a feeding component, a frog-catching component, and a care component. The feeding component throws feed into the paddy field, the frog-catching component herds the frogs to one side of the direction the pull rope 4 is traveling, and the care component cares for the rice and the paddy field. The bottom end of the suspension rope 22 has a cover 23 with a threaded electrical connector. The feeding component and the frog-catching component have cylindrical portions 28 with threaded electrical connectors. The cover 23 has internal threads, and the cylindrical portion 28 has external threads. After the cover 23 and the cylindrical portion 28 are threaded together, the inner end of the cover 23 is electrically connected to the top end of the cylindrical portion 28. The pull rope 4 contains a main circuit, and the suspension rope 22 contains a branch circuit electrically connected to the main circuit. The branch circuit is electrically connected to the cover 23 of the threaded electrical connector, and the main circuit is electrically connected to a power source. The power source is also the power source for the motor 3 on the slide 2. The power source can be a battery located on the top of the slide 2, which is removable for charging, or an external circuit that follows the slide 2 as it slides. In addition, a support plate is provided at the spiral end of the cylinder 28, and a sealing gasket is provided on the support plate. After the cylinder 28 is screwed into the cover 23, the sealing gasket contacts the bottom edge of the cover 23 to achieve a seal and prevent water from entering.

[0062] The feeding assembly includes a cylindrical hopper 24 with a closed top. A movable, snap-fit ​​feed cover is located on one side of the top of the hopper 24. Feed is added into the hopper 24 by opening the cover, and the hopper 24 is closed when the cover is closed. The hopper 24 gradually narrows in diameter downwards, and a discharge port is located at the bottom. A feeding screw 29 is rotatably mounted inside the discharge port. A throwing disc 30 is coaxially connected to the bottom end of the feeding screw 29, positioned below the discharge port. The throwing disc 30 is frustoconical in shape, with its smaller diameter end coaxially connected to the feeding screw 29. Multiple throwing strips 31 are evenly distributed on the throwing disc 30. A micro motor, driven by the feeding screw 29, is located inside the hopper 24. A base 25 is located at the bottom of the micro motor, and a cover 26 encloses the micro motor on the base 25. Multiple connecting rods secure the base 25 to the inner wall of the hopper 24. The top of the feed hopper 24 is equipped with a connecting pipe 27. Multiple connecting rods are provided on the outer wall of the connecting pipe 27, connecting to the inner wall of the feed hopper 24. The bottom of the connecting pipe 27 connects to the machine cover 26. The connecting pipe 27 contains wiring for electrical connection to a micro motor. The top of the connecting pipe 27 extends outside the feed hopper 24 and has a threaded connector 28 for electrical connection to its internal wiring. When the feed hopper 24 is filled with feed, the top cylindrical portion 28 is threadedly connected to the cover 23 at the bottom of the lifting rope 22, allowing power to be supplied to the micro motor. The micro motor drives the feeding screw 29 and the throwing disc 30 to rotate, thus outputting and scattering the feed from the feed hopper 24.

[0063] The feeding assembly operates at the top and above the rice paddies. The length of the hanging rope 22 is adjusted by tying knots in it, thus regulating the height of the feeding assembly. More knots result in a shorter rope 22 and a higher feeding assembly, while fewer knots result in a longer rope 22 and a lower feeding assembly. During feeding, the two sliding blocks 2 slide, driving the pull rope 4 forward. As the pull rope 4 moves, a micro-motor operates, and the feed in the hopper 24 is discharged from the bottom outlet and scattered.

[0064] The frog-catching assembly includes a spherical housing 32. A light source, consisting of multiple LEDs 33 evenly arranged on the outer wall of the housing 32, is mounted on the outer wall of the housing 32. A buzzer is also installed inside the housing 32. Multiple movable plastic plates 34 are suspended from the bottom of the housing 32. The top of the housing 32 also has a cylindrical portion 28 with a threaded electrical connector. The cylindrical portion 28 is electrically connected to the light source and buzzer inside the housing 32. Similarly, a support plate with a sealing gasket is provided at the spiral end of the cylindrical portion 28. When catching rice frogs, the height of the frog-catching assembly is controlled by tying a knot in the rope 22, maintaining a small gap between the assembly and the bottom of the paddy field or the surface of the liquid. The rope 4 moves from one end of the paddy field to the other, with a trap set beforehand at the edge of the paddy field in the direction the rope 4 is moving. Bait and a water source are placed at the trap. The rope 4 is then gradually moved forward. During this process, the LED light 33 of the frog-catching assembly flashes red or yellow light, while a buzzer sounds at a low frequency. The sound and light signals of the LED light 33 and the buzzer are triggered intermittently, for example, triggering for 5 seconds and stopping for 10 seconds, to avoid continuous stimulation that could cause stress to the rice frogs. The rope 4 gradually moves from one end of the paddy field to the end where the trap is set, gradually driving the rice frogs to the trap and catching them.

[0065] The nursing component includes a base 35, with a metal weight 36 at the bottom of the base 35. The weight 36 is threadedly connected to the base 35 and is detachable. The base 35 is cylindrical, with multiple flexible disturbance rods 37 evenly spaced on its outer circumference. The disturbance rods 37 are arranged radially along the base 35 and can be silicone strips. A screw cylinder 38 is coaxially connected to the top of the base 35. The shape of the screw cylinder 38 is adapted to the cover 23 of the threaded electrical connector and is threadedly engaged. The length of the screw cylinder 38 is less than that of the cylinder 28 of the threaded electrical connector. After the screw cylinder 38 is fully screwed into the cover 23, it will not be electrically connected to it. Similarly, a support plate is provided at the spiral end of the screw cylinder 38, and a sealing gasket is provided on the support plate.

[0066] When the care component is used for rice and paddy field care, the same method applies: the pull rope 4 is gradually moved from one end of the paddy field to the other end. The length of the hanging rope 22 is controlled by knotting, so that the care component is positioned above the rice. As the care component moves with the pull rope 4, the disturbance rod 37 of the care component will stir the rice seedlings, which can increase air circulation in the field and reduce the probability of disease occurrence. Especially in the morning when there is a lot of dew, it can knock off the dew on the rice leaves, destroy the high humidity environment required for the germination of rice blast and sheath blight pathogens, and also provide a good growth environment for rice frogs.

[0067] Example 2

[0068] like Figure 9 As shown, this embodiment adds a length adjustment measure for the pull rope 4 based on embodiment 1, so that the two track components can be non-parallel. This embodiment is applicable to irregularly shaped paddy fields (non-rectangular) and situations where the two track components are tilted in the direction of travel of the pull rope 4.

[0069] One of the two slides 2 has an adjusting seat 39 hinged to its inner side. The adjusting seat 39 is rotatable with its rotation axis vertical. A first servo motor 40 is provided on the slide 2 to drive the adjusting seat 39 to rotate. A first monitoring component that cooperates with the first servo motor 40 is provided on the adjusting seat 39. A control box containing electrical components such as a PLC is provided on the adjusting seat 39. The first servo motor 40 and the first monitoring component are electrically connected to the control box.

[0070] A support 41 is provided on the side of the adjusting seat 39 away from the slide 2. A winding reel 46 is rotatably mounted on one side of the support 41, and a second servo motor 42 with torque control mode and brake is provided on the other side to drive the winding reel 46 to rotate. A second monitoring component is also provided on the support 41 on the side of the winding reel 46 away from the adjusting seat 39, which cooperates with the second servo motor 42. The second servo motor 42 controls the winding reel 46 to take in or release the wire based on the state of the pull rope 4 monitored by the second monitoring component. The second servo motor 42 and the second monitoring component are electrically connected to the control box.

[0071] like Figure 10 and Figure 11 As shown, the second monitoring component includes a winding roller 47 rotatably mounted on the support 41. The winding roller 47 is parallel to the winding reel 46. The height of the winding roller 47 is higher than that of the winding reel 46. When the winding reel 46 is fully wound up the pull rope 4, the winding roller 47 is still above the pull rope 4 on the winding reel 46. That is, the winding roller 47 is always at a high position. The pull rope 4 passes over the upper part of the winding roller 47 and is then wound into the winding reel 46 from above. A slide rail 52 is provided on the support 41 on the side of the winding roller 47 away from the winding reel 46. The slide rail 52 is arranged vertically, and a slider is slidably provided in the slide rail 52. A sensor for monitoring the position of the slider is provided in the slide rail 52, which can be a magnetostrictive sensor. Two rotating rods 48 parallel to the winding roller 47 are rotatably provided on the slider. The distance between the two rotating rods 48 is adapted to the outer diameter of the pull rope 4. The pull rope 4 passes between the two rotating rods 48. The two rotating rods 48 are rotatably provided on the slider. Therefore, the two rotating rods 48 are far away from the slider. That is, there is a gap between the two rotating rods 48 on the side away from the support 41, which allows the suspension rope 22 to pass laterally.

[0072] When the second monitoring component is working, it sets the standard position range of the slider, that is, sets the two end values ​​of the slider within the slide rail 52. Since the slide rail 52 is vertical in this embodiment, the two end values ​​are the highest and lowest values ​​of the slider within the slide rail 52. When the slider is within this standard position range, the second servo motor 42 stops running and brakes, and the winding reel 46 is fixed and will not perform winding or unwinding. When the slider exceeds the highest value of the standard position range, the tension of the pull rope 4 increases, and the pull rope 4 tends to tighten. This indicates that the distance between the two track components has increased. When the length of the pull rope 4 increases, the second servo motor 42 operates to control the winding reel 46 to release the rope, so that the length of the pull rope 4 matches the distance between the two track components. Conversely, when the slider is below the minimum value of the standard position range, the pull rope 4 is further released, that is, the distance between the two track components is reduced. The pull rope 4 falls under its own weight and the weight of the auxiliary components (working components). The second servo motor 42 controls the winding reel 46 to reel in the rope, winding the pull rope 4 to make its area taut. The lifting of the pull rope 4 during the tensioning process will drive the slider to rise, so that the slider returns to the standard position range.

[0073] The second monitoring component allows the length of the pull rope 4 to be adjusted according to the distance between the two track components. This prevents the pull rope 4 from breaking due to an increase in the track distance, and also prevents it from falling into the paddy field due to a decrease in the track distance. When the pull rope 4 experiences a slight sag due to its own weight, the winding roller 47 raises one end of the pull rope 4, further strengthening the initial inclination of that end. This ensures that when the distance between the two ends of the pull rope 4 changes, the pull rope 4 will sway noticeably whether it is taut or sags. This swaying phenomenon is used to monitor the state of the pull rope 4, allowing the winding reel 46 to reel in or untie the line in time, thus stabilizing the state of the pull rope 4 in the paddy field and preventing it from becoming taut and breaking, as well as from falling to the ground.

[0074] like Figure 10 As shown, the first monitoring component includes a bracket 49 positioned above the winding roller 47. A downward-facing smart camera 50 is mounted on the bracket 49, and a marker 51 parallel to the winding roller 47 is also mounted on the bracket 49. The image captured by the smart camera 50 shows the pull rope 4 and the marker 51. Under normal circumstances, the pull rope 4 and the marker 51 are perpendicular. When the smart camera 50 captures an image showing that the pull rope 4 and the marker 51 are no longer perpendicular and the pull rope 4 is tilted, the control box controls the first servo motor 40 to drive the adjusting seat 39 to swing. The adjusting seat 39 swings towards the side with a small angle between the pull rope 4 and the marker 51. When the pull rope 4 and the marker 51 are perpendicular, both sides of the pull rope 4 are at right angles to the marker 51. When the pull rope 4 is tilted, the two sides of the pull rope 4 are at small angles (acute angles) and large angles (obtuse angles) to the marker 51, respectively. The adjusting seat 39 swings until the marker 51 and the pull rope 4 are perpendicular again.

[0075] The first monitoring component is set up so that during the movement of the pull rope 4, the tilt of the winding reel 46 caused by the speed difference between the two slide blocks 2 and the tilt of the track component is corrected, so that the winding reel 46 remains perpendicular to the pull rope 4, which is conducive to the winding and unwinding of the pull rope 4 and also prevents the pull rope 4 from falling off the winding reel 46.

[0076] like Figure 9 and Figure 12 As shown, the adjustment seat 39 is also provided with a storage tray 43 for storing the lifting rope 22 and working components. The storage tray 43 is located on the adjustment seat 39 on the side of the winding reel 46 away from the support 41 and is set vertically. The storage tray 43 has a storage groove 53 arranged in a spiral trajectory. The storage groove 53 is for the lifting rope 22 to slide into. The width of the storage groove 53 is greater than the outer diameter of the lifting rope 22. The opening of the storage groove 53 is located at the top of the storage tray 43 and its position is adapted to the entry point of the pull rope 4 at the top of the winding reel 46. A metal storage rack 44 is connected to the slot of the top storage groove 53 of the storage tray 43. The storage rack 44 is strip-shaped and includes a flip section and a curved section connected in sequence. The curved section is connected to the top slot of the storage tray 43. The curved section is coplanar with the storage tray 43, that is, it is arranged in a vertical state. The trajectory of the curved section is matched with the trajectory of the pull rope 4 passing between the winding disc 46, the winding roller 47 and the two rotating rods 48. The curved section starts obliquely upward from the top of the storage tray 43, reaches the side of the winding roller 47 and then bends downward and extends.

[0077] The end of the flipping section away from the bending section is directly below the trajectory of the pull rope 4 and is arranged horizontally. The bending section is coplanar with the winding reel 46. Therefore, there is a gap between the two ends of the flipping section in the direction of travel of the pull rope 4. The end of the flipping section away from the bending section is horizontal, and the end of the flipping section connected to the bending section is vertical to match the bending section. Therefore, the flipping section also flips 90 degrees during the inclined extension in the direction of travel of the pull rope 4. The storage rack 44 is provided with a sliding groove 54 that matches the size of the storage slot 53. The sliding groove 54 is arranged along the trajectory of the storage rack 44. The inner walls of both the sliding groove 54 and the storage slot 53 are provided with a layer of polytetrafluoroethylene material to reduce their sliding friction with the hanging rope 22.

[0078] Two guide plates 45 are provided at the opening of the slide groove 54 of the flip section of the storage rack 44. The two guide plates 45 are arranged vertically and include a straight section and an inclined section. The straight section is set parallel to the pull rope 4 and is connected to the flip section of the storage rack 44. The inclined section is connected to the end of the straight section away from the storage rack 44. The free end of the inclined section is inclined outward, so that the inclined sections of the two guide plates 45 form an isosceles trapezoidal flared structure. The guide plates 45 are made of polytetrafluoroethylene and the guide plates 45 are guided by the sliding rope 22 sliding into the slide groove 54.

[0079] like Figure 13As shown, the suspension rope 22 is equipped with a rope buckle 55 that mates with the sliding groove 54 and the storage groove 53. The rope buckle 55 is movably engaged with the suspension rope 22, and its position on the suspension rope 22 is adjustable. The upper part of the rope buckle 55 is arc-shaped, and the lower part is a truncated cone with the smaller diameter end facing down. A through hole with an inner diameter matching the outer diameter of the suspension rope 22 is provided in the middle of the rope buckle 55. The outer diameter of the upper part of the rope buckle 55 is larger than the width of the sliding groove 54 and the storage groove 53, and the minimum outer diameter of the lower truncated cone part is smaller than the width of the sliding groove 54 and the storage groove 53. This allows the lower truncated cone part of the rope buckle 55 to slide within the sliding groove 54 and the storage groove 53 without the rope buckle 55 passing through them. The upper truncated cone part of the rope buckle 55 is threaded with multiple screws. Rotating the screws allows them to contact the suspension rope 22, thus fixing the rope buckle 55 to the suspension rope 22. Loosening the screws allows the rope buckle 55 to slide on the suspension rope 22 to adjust its position.

[0080] The portion between the cord buckle 55 and the cover 23 of the threaded electrical connector at the bottom of the suspension rope 22 slides on the storage rack 44 and the storage tray 43. The height of the flip-up end of the storage rack 44 is between the cord buckle 55 and the cover 23 when the suspension rope 22 is vertical. Since the working heights of the three working components are different, there are three different storage racks 44. The height of the flip-up end of each storage rack 44 is different, and the height of the flip-up end of the storage rack 44 matches the height of the cord buckle 55 and the cover 23 of the suspension rope 22 on the corresponding working component. The storage rack 44 and the storage tray 43 are detachably connected, such as... Figure 12 As shown, each side of the storage rack 44 is provided with a connecting plate 57 whose shape is adapted to it, and the bottom surface of the connecting plate 57 is bolted to the top of the storage tray 43.

[0081] The thickness of the storage rack 44 gradually increases from the end connected to the guide plate 45 of the flip section towards the storage tray 43, until the thickness matches the distance between the rope buckle 55 on the suspension rope 22 and the cover 23. The thickness of the storage tray 43 also matches the distance between the rope buckle 55 on the suspension rope 22 and the cover 23, and its thickness is slightly smaller than the distance between the rope buckle 55 and the cover 23. The storage rack 44 at the entrance of the flip section has the smallest thickness to allow the suspension rope 22 between the rope buckle 55 and the cover 23 to slide smoothly into the storage rack 44. The top of the cover 23 of the threaded electrical connector is also provided with a second proximity switch 56. After the suspension rope 22 gradually slides into the storage rack 44, the second proximity switch 56 at the top of the cover 23 comes into contact with the storage rack 44 and the storage tray 43. The activation of the second proximity switch 56 causes the working component to stop working.

[0082] Depending on the working height of different working components, the length of the suspension rope 22 is first adjusted by knotting. The pull rope 4, wound on the winding reel 46, has its knotted end located between the storage tray 43 and the winding reel 46. During system operation, the two slides 2 move along the track assembly, and the working components perform corresponding operations. As the pull rope 4 moves, the two track assemblies are no longer parallel as in Embodiment 1; the track assemblies will tilt, and the distance between them will change. When the first monitoring component detects that the slides 2 and pull rope 4 are tilted, the first servo motor 40 drives the adjusting seat 39 to rotate so that the winding reel 46 remains perpendicular to the pull rope 4. When the second monitoring component detects that the pull rope 4 changes in tension or slack due to the change in the distance between the two slides 2, the second servo motor 42 performs corresponding unwinding or rewinding to maintain tension. The position of rope 4 on the paddy field, and to prevent rope 4 from breaking, during the winding process of rope 4 being wound by reel 46, the suspension rope 22 moves between the two guide plates 45. Since the suspension rope 22 may swing, the inclined section of the guide plate 45 is set to guide the suspension rope 22, allowing the suspension rope 22 to slide smoothly into the straight section of the guide plate 45. After the suspension rope 22 enters the straight section of the guide plate 45, the swing of the suspension rope 22 in the direction of rope 4 is restricted. As the suspension rope 22 slides towards the reel 46 with the rope 4, the suspension rope 22 between the rope buckle 55 and the cover 23 slides into the storage rack 44. As the rope 4 is wound... As the reel 46 winds up, the suspension rope 22 continues to slide along the storage frame 44. The flipping section of the storage frame 44 causes the suspension rope 22 to gradually swing upwards until it approaches perpendicularity to the pull rope 4. The thickness of the storage frame 44 gradually increases, causing the rope buckle 55 and the cover 23 at its bottom end of the suspension rope 22 to slide into contact with both sides of the storage frame 44 as a limiting measure. The pull rope 4 is wound into the winding reel 46, and the suspension rope 22 is pulled into the storage reel 43. When the working components are the feeding component and the frog-catching component, the second proximity switch 56 on the cover 23 comes into contact with the storage frame 44 and the storage reel 43, de-energizing the feeding component and the frog-catching component. To prevent further operation, the length of the hanging rope 22 between the rope buckle 55 and the pull rope 4 is slightly longer than the distance between the storage frame 44 and the storage tray 43 and the winding reel 46. The pull rope 4 is pulled diagonally, causing the hanging rope 22 to slide on the storage frame 44 and the storage tray 43. The storage tray 43 and the storage frame 44 temporarily store the collected working components and the hanging rope 22. Correspondingly, when the pull rope 4 is released by the winding reel 46, the hanging rope 22 is pulled and slides outward until it moves out of the storage frame 44. After the second proximity switch 56 of the cover 23 leaves the storage tray 43 or the storage frame 44, the working components can enter the paddy field to resume operation. This embodiment allows the system to successfully carry out rice-frog farming even in irregularly shaped paddy fields.

Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of the patent of the present invention.
