Description

Technical Field

[0001] This invention relates to the field of water spinach cultivation technology, specifically to a wetland water spinach cultivation device. Background Technology

[0002] In wetland restoration projects, to effectively improve the wetland's ecological environment, it's common practice to plant relatively easy-to-establish and propagate wetland plants, such as reeds and loosestrife. These plants possess strong adaptability and vitality, quickly taking root and growing in wetland environments, playing a crucial role in maintaining the ecological balance and water quality of wetlands. However, from an economic perspective, simply planting reeds and loosestrife has limitations. While they possess important ecological functions, they don't directly bring significant economic benefits to wetland restoration projects. In the field of wetland agriculture, water spinach, as a unique vegetable variety, has shown enormous development potential. Water spinach has excellent adaptability to wetland environments, growing well in moist, loose soil; simultaneously, it has high economic value, stable market demand, and can bring considerable economic returns to growers. Therefore, improving the planting efficiency and quality of water spinach in wetland environments has become a focus of continuous attention within the industry.

[0003] However, in actual cultivation, especially in the cutting stage, traditional methods face numerous thorny problems. The high moisture content and loose texture of wetland soil pose significant challenges to manual cutting. Workers expend considerable physical strength during cutting, resulting in extremely high labor intensity and low efficiency. Furthermore, traditional fertilization and growth-promoting measures are often separated from the cutting process. Fertilization and growth-promoting agents are applied only after cutting, making it impossible to precisely target the fertilizer and agents to the cutting site. Large amounts of fertilizer are scattered on the soil surface or away from the plant roots, not only wasting fertilizer but also reducing the water spinach's nutrient utilization efficiency. To achieve the desired growth results, growers are forced to increase the amount of fertilizer and growth-promoting agents used, undoubtedly further increasing production costs. Moreover, inaccurate fertilization can negatively impact the wetland soil environment and disrupt the wetland's ecological balance.

[0004] Therefore, in view of this, the inventors proposed a wetland water spinach cultivation device to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a wetland water spinach cultivation device to solve the problems of low efficiency of manual cutting propagation and low nutrient utilization caused by inaccurate fertilization and growth promotion measures in existing wetland water spinach cultivation.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A wetland water spinach planting device includes a machine body walking assembly, a planting plate, a planting frame, and a planting execution mechanism. The planting plate is reciprocally slidably mounted on the machine body walking assembly, the planting frame is fixed on the planting plate, and the planting execution mechanism is movably mounted on the planting frame.

[0008] The planting board has several planting troughs for placing water spinach vines;

[0009] The system includes a linkage component, a nutrient tank, and a manure tank. The linkage component, the nutrient tank, and the manure tank are installed on the planting frame. The linkage component is connected to the nutrient tank, the manure tank, and the planting execution mechanism, and is used to transport the nutrient solution from the nutrient tank and the manure liquid from the manure tank to the planting execution mechanism.

[0010] It also includes a driving component, which is connected to the planting execution mechanism and the linkage component, and is used to drive the planting execution mechanism to rotate along a preset trajectory so as to insert the water spinach vines in the planting trough into the wetland one by one.

[0011] Furthermore, the planting execution mechanism includes a spray column, at least one planting execution unit, and several cutting claws, with each of the cutting claws spaced apart along the length of the spray column;

[0012] The planting execution unit includes a first link and a second link hinged to the planting frame. A third link is hinged to the first link and fixedly connected to the spray column. The end of the second link is hinged to the middle of the third link. The driving member is connected to the second link and is used to drive the second link to rotate.

[0013] According to the above technical solution, when the driving component drives the second connecting rod to rotate around the axis, the second connecting rod pushes the third connecting rod to perform a compound swing motion through the central hinge point. The third connecting rod is fixedly connected to the spray column, thereby driving the entire spray column to move back and forth along a preset trajectory (such as an ellipse or a swing curve). Multiple cutting claws fixed on the spray column move synchronously with its trajectory. During the forward movement, the tips of the cutting claws are periodically inserted into the wet soil at the notch of the planting board by the mechanical lever action, thus completing the cutting and planting of water spinach vines.

[0014] Furthermore, the driving component includes a gasoline engine, a first rotating shaft, a second rotating shaft, and a third rotating shaft. The gasoline engine, the first rotating shaft, and the second rotating shaft are all mounted on the planting frame. The gasoline engine is connected to the first rotating shaft. A first sprocket is provided on both the first rotating shaft and the second rotating shaft, and a first chain is tensioned between the two first sprockets.

[0015] It also includes a first power box and a second power box. The first power box is fixedly mounted on the planting frame, and the second power box is fixedly mounted on the machine body walking assembly. The first rotating shaft passes through the first power box, and a first bevel gear is coaxially fixedly connected to the first rotating shaft. The first bevel gear is located inside the first power box. One end of the third rotating shaft extends into the first power box and is connected to a second bevel gear. The first bevel gear meshes with the second bevel gear.

[0016] According to the above technical solution, power distribution and motion control are achieved through multi-axis linkage and bevel gear transmission. After the gasoline engine starts, it drives the first rotating shaft to rotate. The first rotating shaft drives the second rotating shaft to rotate synchronously through the first sprocket and chain, providing basic power for subsequent operations. At the same time, the first bevel gear on the first rotating shaft meshes with the second bevel gear (at the end of the third rotating shaft) in the first power box, transmitting power to the third rotating shaft. The second rotating shaft drives the cutting roller of the machine body's walking assembly to rotate through the bevel gear set (third and fourth bevel gears) in the second power box, realizing rotary cutting and loosening of wetland soil. The first rotating shaft, through a crank-rocker mechanism, links the spray column of the planting actuator, driving it to reciprocate along a swing trajectory to complete the cutting operation. This design, through the combination of chain drive and bevel gear set, realizes the coordinated operation of multiple processes such as loosening soil, transplanting, and fertilizing, ensuring efficient power transmission and precise control.

[0017] Furthermore, the spray column includes a cylindrical tube and a square steel tube, the square steel tube being fixed on the cylindrical tube, and the cylindrical tube being connected to the third connecting rod;

[0018] A first liquid storage cavity is formed inside the cylindrical tube, and a second liquid storage cavity is formed inside the square steel tube;

[0019] The square steel tube is provided with several spray holes that communicate with the second liquid storage chamber;

[0020] The cutting claw has a hollow structure and is fixed on the cylindrical tube and connected to the first liquid storage cavity.

[0021] Furthermore, the linkage includes a mounting plate, a dual-channel cylinder, and a turntable. The mounting plate is fixed on the planting rack, and the dual-channel cylinder is fixed on the mounting plate. A movable plug is slidably connected inside the dual-channel cylinder, and the movable plug divides the dual-channel cylinder into a first chamber and a second chamber, which are isolated from each other.

[0022] The turntable is coaxially connected to the first rotating shaft. A drive column is eccentrically connected to the turntable. A slip ring is slidably connected to the drive column. A push rod is connected to the slip ring. The end of the push rod extends into the dual-channel cylinder and connects to the movable plug.

[0023] Furthermore, the dual-channel cylinder is connected to a first connecting pipe, a second connecting pipe, a third connecting pipe, and a fourth connecting pipe. A first one-way valve diaphragm is installed on the first connecting pipe, a second one-way valve diaphragm is installed on the second connecting pipe, a third one-way valve diaphragm is installed on the third connecting pipe, and a fourth one-way valve diaphragm is installed on the fourth connecting pipe.

[0024] One end of the first connecting tube is connected to the first chamber, and the other end of the first connecting tube is connected to the second liquid storage chamber;

[0025] One end of the second connecting tube is connected to the first chamber, and the other end of the second connecting tube is connected to the nutrient tank;

[0026] One end of the third connecting pipe is connected to the second chamber, and the other end of the third connecting pipe is connected to the first liquid storage chamber;

[0027] One end of the fourth connecting pipe is connected to the second chamber, and the other end of the fourth connecting pipe is connected to the manure box.

[0028] Furthermore, the cylindrical tube has a circular structure, and the angle between the insertion claw and the fourth connecting tube is α, where α is less than 135 degrees.

[0029] According to the above technical solution, by designing the angle between the cutting claw and the first connecting pipe to be less than 135 degrees, the bottom of the circular pipe can form a semi-circular arc. When the cylindrical pipe is in a horizontal state, the semi-circular arc is used to temporarily store the manure. When the cylindrical pipe changes from a horizontal state to a vertical state, the manure temporarily stored in the semi-circular arc is poured into the cutting claw for precise fertilization.

[0030] Furthermore, the cylindrical tube is provided with a channel for connecting the first liquid storage chamber and the second liquid storage chamber, and a fifth one-way valve diaphragm is provided on the channel.

[0031] Furthermore, the machine body walking assembly includes a housing and a cutting roller rotatably connected inside the housing, wherein the cutting roller is provided with a plurality of roller cutters;

[0032] The second power box contains a rotatably connected third bevel gear and a fourth bevel gear that mesh with each other. The third bevel gear is coaxially connected to the third rotating shaft, and the fourth bevel gear is coaxially fixedly connected to the cutting roller.

[0033] Furthermore, a fourth rotating shaft is rotatably connected inside the housing, an eccentric ring is mounted on the fourth rotating shaft, and a contact block is fixedly mounted on the planting plate, with the eccentric ring abutting against the contact block; when the fourth rotating shaft rotates, the eccentric ring can drive the contact block to slide left and right;

[0034] The cutting roller and the fourth rotating shaft are coaxially connected to a second sprocket, and a second chain is tensioned between the two second sprockets.

[0035] According to the above technical solution, when the cutting roller rotates, the roller continuously cuts the wetland soil. At the same time, when the eccentric ring on the fourth rotating shaft rotates with the shaft, it drives the contact block to slide back and forth, pushing the planting plate to periodically translate on the shell. This allows the water spinach vines to be planted through a non-linear cutting pattern formed by the swinging trajectory of the equipment, which can effectively disperse the space competition between plants, allowing each water spinach to receive more light and air circulation, reducing the risk of root hypoxia and disease caused by dense growth. Secondly, the swinging planting path can adapt to the soft and uneven terrain of the wetland, avoiding excessive soil compaction caused by straight-line movement, protecting the wetland ecological structure while improving root aeration. In addition, the non-linear interval, combined with the equipment's linkage spraying system, can achieve differentiated and precise delivery of manure and nutrient solution—the manure near the insertion point of the cutting claw is concentrated to supply the nutrients needed for root development.

[0036] The beneficial effects of this invention are:

[0037] This invention integrates cutting propagation with a dual-cavity linkage system, achieving synchronized mechanized operation of the three processes: cutting propagation, manure application, and spraying. The spray column employs a split-cavity design (a cylindrical manure chamber and a square steel nutrient solution chamber), which, combined with the piston pump effect of the dual-channel cylinder in the linkage, completes a dual fertilization mode within a single oscillation cycle: precise root injection of manure (via hollow cutting claws) and foliar atomization of nutrient solution. This breaks through the technical barrier of the single-operation mode of traditional planting equipment. The specially designed fifth one-way valve membrane dynamic mixing channel enables the manure and nutrient solution to form an instantaneous micro-mixing under the action of pressure difference. Part of the nutrient solution is sprayed out through the spray hole to achieve atomized spraying of nutrient solution onto the water spinach vines; the other part of the nutrient solution enters the first storage chamber from the second storage chamber through the channel between the cylindrical tube and the square steel tube. The microorganisms in the manure and the trace elements in the nutrient solution are activated by mixing to form a symbiotic system, which accelerates the absorption efficiency of nutrients by the water spinach roots. The equipment can simultaneously complete precise fertilization and soil improvement during the cutting process, significantly improving the stress resistance and growth rate of wetland water spinach.

[0038] This invention uses an eccentric ring-contact block mechanism to drive the planting board to slide laterally, forming a three-dimensional motion trajectory with the combined oscillation of the spray column. The cutting roller transmission system makes the cutting points present a non-linear distribution feature, and the adjacent plants form an interlaced layout, which significantly reduces the risk of lodging in wetland environments, improves light energy utilization, and dynamically adjusts the plant spacing to adapt to the complex terrain of wetlands.

[0039] This invention utilizes the air pressure generated by the compression of the linkage component, releasing the airflow through a micro-hole at the tip after the cutting claw completes the insertion action. This design enables the water spinach vines to detach quickly, avoiding the problem of seedlings getting stuck in sticky soil. At the same time, it forms micro-air chambers in the soil to promote oxygen exchange in the roots, significantly improving the success rate of cuttings and accelerating root development.

[0040] This invention constructs a closed-loop system of manure, nutrient solution, and soil improvement: the negative pressure adsorption of the dual-channel cylinder enables pump-free delivery, the atomization design of the spray column improves the utilization rate of nutrient solution, and the rotary-cut weeds are crushed and backfilled into the cutting holes to form in-situ green manure coverage, which significantly reduces the consumption of external resources.

[0041] Other advantages, objectives, and features of this application will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be learned from practice of this application. The objectives and other advantages of this application may be realized and obtained through the detailed embodiments described below. Attached Figure Description

[0057] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0058] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0059] This embodiment proposes a wetland water spinach cultivation device, such as... Figures 1 to 14 As shown, the device includes a walking assembly 1, a planting plate 2, a planting frame 3, and a planting actuator 4. The planting plate 2 is slidably mounted on the walking assembly 1, which can be connected to a traction machine to achieve traction-driven operation. The planting frame 3 is fixed on the planting plate 2, and the planting actuator 4 is movably mounted on the planting frame 3. The planting plate 2 has several planting troughs 21 for placing water spinach vines. In this embodiment, there are four planting troughs 21, and each planting trough 21 has a notch 211 at its bottom.

[0060] Linkage component 5, nutrient tank 6, and manure tank 7 are installed on planting frame 3. Specifically, planting frame 3 has a lid 31, on which nutrient tank 6 and manure tank 7 are installed. Linkage component 5 connects to nutrient tank 6, manure tank 7, and planting execution mechanism 4, and is used to transfer the nutrient solution from nutrient tank 6 and the manure liquid from manure tank 7 to planting execution mechanism 4.

[0061] It also includes a drive component 8, which is connected to the planting actuator 4 and the linkage component 5. The drive component 8 drives the planting actuator 4 to rotate along a preset trajectory, so as to insert the water spinach vines in the planting trough 21 one by one into the wetland. It should be noted that the preset trajectory mentioned in this embodiment refers to the predetermined route along which the insertion claw 43 of the planting actuator 4 performs periodic reciprocating motion along a specific swing trajectory under the cooperative control of the drive component 8. Furthermore, according to the essential spirit of the present invention, those skilled in the art can derive the preset trajectory through a limited number of experiments. Specifically, this trajectory is achieved by a crank-rocker mechanism.

[0062] As a preferred embodiment, such as Figure 4As shown, the planting execution mechanism 4 includes a spray column 41, at least one planting execution unit 42, and several cutting claws 43. Each cutting claw 43 is spaced apart along the length of the spray column 41. In this embodiment, there are two planting execution units 42 and four cutting claws 43. Each cutting claw 43 is fixedly installed on the spray column 41, and each cutting claw 43 is correspondingly set with the notch 211 of each planting trough 21. When the cutting claw 43 operates along the preset trajectory, it will insert the water spinach vines placed in the planting trough 21 into the wetland one by one through the notch 211 of the planting trough 21, thereby realizing rapid cutting operation.

[0063] Specifically, such as Figure 4 As shown, the planting execution unit 42 includes a first link 421 and a second link 422 hinged to the planting frame 3. A third link 423 is hinged to the first link 421. The end of the third link 423 is fixedly connected to the spray column 41. The end of the second link 422 is hinged to the middle of the third link 423. The driving member 8 is connected to the second link 422 and is used to drive the second link 422 to rotate.

[0064] According to the above technical solution, when the driving component 8 drives the second connecting rod 422 to rotate, the second connecting rod 422 pushes the third connecting rod 423 to perform a compound swing motion through the middle hinge point. The third connecting rod 423 is fixedly connected to the spray column 41, thereby driving the spray column 41 to swing along the preset trajectory. Multiple cutting claws 43 fixed on the spray column 41 move synchronously with its trajectory. During the forward movement, the tips of the cutting claws 43 are periodically inserted into the wet soil one by one by the water spinach at the notch 211 of the planting board 2 under the action of mechanical lever, thus completing the cutting and planting of water spinach vines.

[0065] As a preferred embodiment, such as Figure 4 , Figure 5 and Figure 6 As shown, the drive component 8 includes a gasoline engine 81, a first rotating shaft 82, a second rotating shaft 83, and a third rotating shaft 84. The gasoline engine 81, the first rotating shaft 82, and the second rotating shaft 83 are all rotatably mounted on the planting frame 3. The gasoline engine 81 is connected to the first rotating shaft 82 and is used to drive the first rotating shaft 82 to rotate. The first rotating shaft 82 and the second rotating shaft 83 are each provided with a first sprocket, and a first chain 85 is tensioned between the two first sprockets. That is, the first rotating shaft 82 drives the second rotating shaft 83 to rotate synchronously through the first sprocket and the chain, providing basic power for subsequent operations.

[0066] like Figure 7 As shown, it also includes a first power box 86 and a second power box 87. The first power box 86 is fixedly mounted on the planting frame 3, and the second power box 87 is fixedly mounted on the machine body walking assembly 1; as shown Figure 4 , Figure 5 and Figure 6As shown, a first rotating shaft 82 passes through a first power box 86, and a first bevel gear 821 is coaxially fixedly connected to the first rotating shaft 82. The first bevel gear 821 is located inside the first power box 86. One end of a third rotating shaft 84 extends into the first power box 86 and is connected to a second bevel gear 841. The first bevel gear 821 and the second bevel gear 841 mesh. It should be noted that, to avoid interference caused by transmission, the third rotating shaft 84 in this embodiment is preferably a flexible shaft; of course, it can be understood that the third rotating shaft 84 can also be implemented by connecting multiple rigid shafts through universal joints.

[0067] In this embodiment, the driving component 8 drives the first rotating shaft 82 to rotate, and the first rotating shaft 82 drives the second rotating shaft 83 and the third rotating shaft 84 to rotate synchronously via chain transmission. The first rotating shaft 82 drives the spray column 41 of the planting actuator 4 to reciprocate periodically along a preset swing trajectory (such as a crank rocker mechanism). The water spinach vines in the planting trough 21 fall down in sequence, and the cutting claw 43 inserts the water spinach vines into the soft wet ground through the notch 211 below the planting trough 21, realizing rapid cutting.

[0068] As a preferred embodiment, such as Figure 9 and Figure 10 As shown, the spray column 41 includes a cylindrical tube 411 and a square steel tube 412. Both the cylindrical tube 411 and the square steel tube 412 are hollow structures. The square steel tube 412 is fixed on the cylindrical tube 411. The combination of the cylindrical tube 411 and the square steel tube 412 achieves a balance between structural strength and lightweight, and also ensures the distribution of manure and nutrient solution through physical isolation. The cylindrical tube 411 is fixedly connected to the third connecting rod 423. A first liquid storage chamber 4111 is formed inside the cylindrical tube 411, and a second liquid storage chamber 4121 is formed inside the square steel tube 412. Several spray holes connected to the second liquid storage chamber 4121 are opened on the square steel tube 412. The nutrient solution in the second liquid storage chamber 4121 can be sprayed out through the spray holes to realize the nutrient solution irrigation of the water spinach vines.

[0069] In this embodiment, the cutting claw 43 is a hollow structure, fixed to the cylindrical tube 411 and connected to the first liquid storage chamber 4111. This allows for precise injection of manure into the loose soil around the roots of the water spinach vines while they are being inserted into the wetland, preventing fertilizer loss. Meanwhile, the spray holes on the square steel tube 412 atomize the nutrient solution through the second liquid storage chamber 4121, promoting root development in the water spinach vines. This compartmentalized synergistic mechanism not only solves the problem of soil compaction caused by fertilizer dispersion on the soil surface in traditional mixed fertilization, but also improves operational continuity through a synchronous operation mode (integrated cutting, manure injection, and nutrient solution spraying). Combined with the rapid cutting operation using a swing trajectory, the application of manure and nutrient solution adapts to the growth needs of water spinach in the complex wetland environment, ultimately achieving the dual goals of increased survival rate and intensive resource utilization.

[0070] As a preferred embodiment, such as Figure 8 As shown, the linkage 5 includes a mounting plate 51, a double-channel cylinder 52, and a turntable 53. The double-channel cylinder 52 is a sealed cylindrical structure with both ends sealed. The mounting plate 51 is fixed on the planting rack 3, and the double-channel cylinder 52 is fixed on the mounting plate 51. A movable plug 54 is slidably connected inside the double-channel cylinder 52. The movable plug 54 divides the double-channel cylinder 52 into a first chamber 55 and a second chamber 56. The first chamber 55 is located above the second chamber 56 and the two are isolated from each other.

[0071] Turntable 53 is coaxially connected to the first rotating shaft 82. A drive column 57 is eccentrically connected to turntable 53, and a slip ring 58 is slidably connected to drive column 57. A push rod 59 is connected to slip ring 58, and the end of push rod 59 extends into the double-channel cylinder 52 and connects to movable plug 54. When turntable 53 rotates with the first rotating shaft 82, the eccentrically positioned drive column 57 pushes slip ring 58 to move, which in turn drives push rod 59 to reciprocate, causing movable plug 54 to periodically compress / release the first chamber 55 and the second chamber 56 within the double-channel cylinder 52.

[0072] Furthermore, such as Figure 4 and Figure 8 As shown, the dual-channel cylinder 52 is connected to a first connecting pipe 521, a second connecting pipe 522, a third connecting pipe 523, and a fourth connecting pipe 524. A first one-way valve diaphragm 5211 is installed on the first connecting pipe 521, a second one-way valve diaphragm 5221 is installed on the second connecting pipe 522, a third one-way valve diaphragm 5231 is installed on the third connecting pipe 523, and a fourth one-way valve diaphragm 5241 is installed on the fourth connecting pipe 524.

[0073] One end of the first connecting pipe 521 is connected to the first chamber 55, and the other end of the first connecting pipe 521 is connected to the second liquid storage chamber 4121; one end of the second connecting pipe 522 is connected to the first chamber 55, and the other end of the second connecting pipe 522 is connected to the nutrient box 6; one end of the third connecting pipe 523 is connected to the second chamber 56, and the other end of the third connecting pipe 523 is connected to the first liquid storage chamber 4111; one end of the fourth connecting pipe 524 is connected to the second chamber 56, and the other end of the fourth connecting pipe 524 is connected to the manure box 7.

[0074] When the first chamber 55 is compressed, the first one-way valve diaphragm 5211 opens, the second one-way valve diaphragm 5221 closes, the third one-way valve diaphragm 5231 closes, and the fourth one-way valve diaphragm 5241 opens. Due to the increased pressure in the first chamber 55, the nutrient solution in the first chamber 55 is allowed to flow into the second storage chamber 4121 (inside the square steel pipe 412) through the first connecting pipe 521 and spray out from the spray hole of the second storage chamber 4121 to atomize and spray the nutrient solution onto the water spinach vines placed in the planting trough 21 to promote the root development of the water spinach vines. At this time, the volume of the second chamber 56 increases due to the movement of the movable plug 54, and a negative pressure is formed inside. The third one-way valve diaphragm 5231 closes to prevent the manure in the first storage chamber 4111 from flowing back into the second chamber 56. The fourth one-way valve diaphragm 5241 opens, and the manure in the manure box 7 is sucked into the second chamber 56 through the fourth connecting pipe 524 to store manure for the next compression cycle.

[0075] Similarly, when the second chamber 56 is compressed, the pressure in the second chamber 56 increases, forcing the third one-way valve diaphragm 5231 to open and the fourth one-way valve diaphragm 5241 to close. The manure in the second chamber 56 enters the first storage tank through the third pipe. Since the first storage tank is connected to the cutting claw 43, it is directly injected into the wet soil at the cutting point through the cutting claw 43, completing the cutting and manure application. At the same time, due to the increase in volume of the first chamber 55, the first one-way valve diaphragm 5211 closes and the second one-way valve diaphragm 5221 opens, allowing nutrient solution to enter the first chamber 55 and reserve nutrient solution for the next compression cycle.

[0076] As a preferred embodiment, such as Figure 9 The cylindrical tube 411 has a channel for connecting the first liquid storage chamber 4111 and the second liquid storage chamber 4121, and a fifth one-way valve diaphragm is provided on the channel. The function of the fifth one-way valve diaphragm is to allow the second liquid storage chamber 4121 to enter the first liquid storage chamber 4111 in one direction.

[0077] In this embodiment, the purpose of setting up the channel is to achieve synergistic effects between the manure and nutrient solution through a dynamic mixing mechanism. When the movable plug 54 compresses the first chamber 55, the fifth one-way valve membrane allows the nutrient solution in the second storage chamber 4121 to be injected back into the manure in the first storage chamber 4111 under the action of pressure difference, forming an instantaneous fusion of organic and inorganic nutrients. That is, when the first rotating shaft 82 rotates, it periodically drives the movable plug 54 to move up and down. When the movable plug 54 moves upward and the first chamber 55 is compressed, the nutrient solution enters the second storage chamber 4121 through the first pipe. Finally, a part of the nutrient solution is sprayed out through the spray hole to achieve atomized spraying of the nutrient solution onto the water spinach vines; another part of the nutrient solution enters the first storage chamber 4111 from the second storage chamber 4121 through the channel between the cylindrical pipe 411 and the square steel pipe 412. The microorganisms in the manure and the trace elements in the nutrient solution are mixed and activated to form a symbiotic system, accelerating the absorption efficiency of nutrients by the water spinach roots. The directional conduction characteristic of the fifth one-way valve membrane not only avoids backflow of fecal liquid into the second liquid storage chamber 4121, but also reduces additional power consumption through pressure-triggered mixing, enabling the equipment to simultaneously complete precise fertilization and soil improvement during the cutting process, significantly improving the stress resistance and growth rate of wetland water spinach.

[0078] As a preferred embodiment, such as Figure 9 As shown, the cylindrical tube 411 has a circular structure, and the angle between the insertion claw 43 and the fourth connecting tube 524 is α, where α is less than 135 degrees. The bottom of the circular tube can form a semi-circular arc. When the cylindrical tube 411 is in an uninserted state (e.g.) Figure 9 As shown), the semi-circular arc serves to temporarily store manure; when the cylindrical tube 411 is in the state of propagating water spinach vines (as shown), Figure 10 As shown, the manure temporarily stored within the semi-circular arc is poured into the cutting claw 43 for precise fertilization, applying manure simultaneously with cutting. It should be noted that when the cutting claw 43 inserts the water spinach vines into the wetland, the soil may become sticky, potentially causing the vines to get stuck at the tip of the claw 43. This implementation addresses this by applying manure simultaneously with cutting. The air pressure in the second chamber 56 is ultimately released from the tip of the cutting claw 43, creating a force that pushes the water spinach vines away from the claw 43 tip, thus improving the cutting process and enabling the water spinach vines to detach quickly. This avoids the problem of seedlings getting stuck in sticky soil and simultaneously forms micro-air chambers in the soil, promoting root oxygen exchange, significantly improving the success rate of cutting and accelerating root development.

[0079] As a preferred embodiment, such as Figure 12The machine body walking assembly 1 includes a housing 11 and a cutting roller 12 rotatably connected inside the housing 11. The cutting roller 12 is provided with a plurality of roller cutters. A third bevel gear 871 and a fourth bevel gear 872 are rotatably connected inside the second power box 87. The third bevel gear 871 is coaxially connected to the third rotating shaft 84, and the fourth bevel gear 872 is coaxially fixedly connected to the cutting roller 12.

[0080] According to the above technical solution, when the gasoline engine 81 drives the third rotating shaft 84 to rotate, the third bevel gear 871 meshes with the fourth bevel gear 872 in the second power box 87, converting the axial rotational power into the horizontal rotational motion of the cutting roller 12. Its roller continuously cuts the surface soil of the wetland during its movement, forming a soft and breathable planting bed. Simultaneously, it cuts and covers the weeds in the wetland to improve fertility. This achieves strict synchronization between the soil loosening operation and the cutting process, ensuring that the newly inserted water spinach vines are located in the soft soil layer, reducing root damage.

[0081] As a preferred embodiment, such as Figure 12 As shown, a fourth rotating shaft 13 is rotatably connected inside the housing 11. An eccentric ring 14 is installed on the fourth rotating shaft 13. A contact block 15 is fixedly installed on the planting plate 2. The eccentric ring 14 abuts against the contact block 15. When the fourth rotating shaft 13 rotates, the eccentric ring 14 can drive the contact block 15 to slide left and right. A second sprocket is coaxially connected to the cutting roller 12 and the fourth rotating shaft 13. A second chain 16 is tensioned between the two second sprockets.

[0082] In this embodiment, as the cutting roller 12 rotates, the rotary cutter continuously cuts the wetland soil. Simultaneously, as the eccentric ring 14 on the fourth rotating shaft 13 rotates with the fourth rotating shaft 13, it drives the contact block 15 to reciprocate left and right, pushing the planting plate 2 to periodically translate on the housing 11. This causes the planted water spinach vines to follow a non-linear propagation trajectory (such as...) formed by the equipment's oscillation path. Figure 14 As shown), cuttings a-cutting b-cutting c-cutting d-cutting e are taken. Because wetland soil is loose in structure due to water saturation, wetlands often have micro-topographical undulations or seasonal water level fluctuations. If straight-line planting is adopted, the water spinach vines are easily impacted by water flow, causing them to lie flat, fall over, or float. Straight-line planting is difficult to flexibly adapt to the complex surface of wetlands. Non-linear trajectory allows the spacing between plants to change dynamically, which reduces root competition and leaf shading between adjacent plants, improves light energy utilization and ventilation efficiency, and can adapt to the irregular undulations of wetland topography, protecting the integrity of the wetland ecological structure.

[0083] The above embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on the present invention are all within the scope of protection of the present invention.
