Description

Technical Field

[0001] This invention belongs to the field of intelligent agricultural power machinery, and specifically relates to a fertilization device and a method for applying fertilizer to promote sprouting during the regeneration season of ratooning rice. Background Technology

[0002] Ratoon rice refers to rice that sprouts new panicles from the stubble after the first rice harvest, achieving two harvests in one crop. To increase yield in the ratoon season, it is necessary to apply topdressing fertilizer 7-10 days before the first rice harvest to promote the sprouting and panicle formation of the new shoots. Currently, the application of topdressing fertilizer for ratoon rice in the ratoon season is mainly done manually or by machinery. Manual fertilization is not only labor-intensive but also inefficient, and cannot meet the needs of large-scale planting.

[0003] Chinese Patent CN113632625B discloses an automatic fertilization device for promoting sprouting fertilizer during the regeneration season of ratooning rice. This device includes a support frame, a two-stage fertilizer discharge device, and an air distribution device. The two-stage fertilizer discharge device has a hopper, a fertilizer discharge wheel, and a feeding box. The fertilizer discharge wheel has a distribution groove on its outer circumference, and the feeding box contains fertilizer boxes. A first fertilizer discharge gear and a second fertilizer discharge gear are fixed to two fertilizer discharge drive shafts, respectively. When the two gears mesh, a discharge gap is formed between the tooth tip and the corresponding tooth root to temporarily store the sprouting fertilizer. The air distribution device connects to the inlet of each fertilizer box through an exhaust fertilizer pipe, and each pipe outlet has a downward-facing fertilizer discharge nozzle.

[0004] While the aforementioned fertilization equipment can automatically apply fertilizer to promote seedling growth, the application of this fertilizer during the ratooning season for ratooning rice must be carried out before the first harvest of the rice. At this time, the rice panicles are densely packed above the rice plants. If fertilizer is applied directly from above the rice plants, most of the fertilizer will fall onto the surface of the panicles and will not effectively penetrate into the soil below. This not only reduces fertilizer utilization but also easily causes seedling burn due to direct contact between the fertilizer and the rice plants. If the fertilizer nozzle is lowered below the rice panicles for application, the nozzle and its supporting frame are prone to knocking over the rice plants during the forward movement, causing damage and ultimately affecting the final yield of the ratooning rice. Summary of the Invention

[0005] In response to the problems in related technologies, this invention proposes a fertilization device and a method for applying fertilizer to promote sprouting during the regeneration season of ratooning rice, so as to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a fertilization device, comprising a walking section, a dividing section, and a fertilization section. The walking section can drive the dividing section and the fertilization section to move and walk. The dividing section can push the crops to both sides to divide and walk when moving and walking. The fertilization section can apply fertilizer in the gaps between the crops pushed and walked by the dividing section. The dividing section includes a spacing adjustment section and multiple dividers. The spacing adjustment section can simultaneously drive multiple dividers to move and spread or move and retract to adjust the spacing between adjacent dividers. The fertilization unit includes a fertilizer storage unit, a fertilizer conveying unit, and multiple feeding and fertilization components. Each feeding and fertilization component is provided with two feeding and fertilization units. The two feeding and fertilization units are respectively located on both sides of the rear end of the corresponding divider. The multiple feeding and fertilization units are connected to the fertilizer storage unit through the fertilizer conveying unit, so that the fertilizer storage unit can convey fertilizer to each feeding and fertilization unit through the fertilizer conveying unit. The two fertilization units within the fertilization assembly can move and expand to both sides when the divider moves and spreads, thereby increasing the distance between the two fertilization units. The two fertilization units can also move inward and close together when the divider moves and retracts, thereby decreasing the distance between the two fertilization units. The traveling unit is a high-clearance self-propelled plant protection vehicle, which is also equipped with an intelligent controller connected to the divider and fertilization units to achieve intelligent automatic control of the fertilization equipment.

[0007] Preferably, the spacing adjustment unit includes an adjustment drive unit and a positioning frame. The positioning frame is fixedly installed on the traveling part. Multiple sets of limiting guide shafts are fixedly installed inside the positioning frame, and multiple adjustment seats that slide with the limiting guide shafts are installed on the positioning frame.

The lifting drive component can drive the adjustment plate to move up and down relative to the positioning frame. When the adjustment plate moves up and down relative to the positioning frame, the adjustment plate can drive multiple guide adjustment rods to move synchronously to retract or extend synchronously through the multiple guide adjustment slots on it, so as to adjust the distance between adjacent guide adjustment rods. The multiple guide adjustment rods are equidistantly distributed when retracting or extending. The lifting drive component is a cylinder, a hydraulic telescopic shaft, or an electric telescopic shaft. The lifting drive component is fixedly installed on the walking part, and the telescopic end of the lifting drive component is fixedly connected to the adjustment plate.

[0009] Preferably, the positioning seat is locked and fixedly installed on the adjusting seat by an adjustable connector. The adjustable connector can drive the positioning seat to move left and right along the adjusting seat to adjust the installation position of the positioning seat and the divider on the adjusting seat. The adjustable connector includes a side plate and a fastening bolt. The side plate is fixedly installed on one side of the positioning seat. The side plate is provided with a strip-shaped connecting groove. The fastening bolt can pass through the strip-shaped connecting groove and be screwed onto the adjusting seat.

[0010] Preferably, the fertilizer storage section includes a fertilizer box, which is fixedly installed on the walking section, and a material discharge chute is provided at the bottom of the fertilizer box; The fertilizer conveying unit includes an outer protective cylinder, which is connected and installed below the material chute. The bottom end of the outer protective cylinder is connected and installed with multiple material hoppers that are connected one-to-one with the material dispensing and fertilization components. A rotary feeding unit is rotatably installed inside the outer protective cylinder. The rotary feeding unit can reciprocate to receive the fertilizer falling from the material chute during rotation and convey the collected fertilizer to each material hopper below. The fertilizer in the material hopper is then dispensed and fertilized by the material dispensing and fertilization components. A partition is also fixedly installed inside the hopper, which divides the hopper into two discharge chambers. The two discharge chambers are respectively connected to two discharge fertilization units in the discharge fertilization assembly.

[0011] Preferably, the rotary feeding unit includes a rotary drive and a discharge roller. The discharge roller is rotatably mounted inside the outer protective cylinder. The outer ring of the discharge roller is provided with multiple fertilizer conveying grooves. The rotary drive can drive the discharge roller to rotate continuously, so that the fertilizer conveying grooves on the discharge roller reciprocate between the discharge trough and the discharge hopper. The rotary drive includes a motor, and the motor is drivenly connected to one end of the discharge roller.

[0012] Preferably, the feeding and fertilizing assembly includes a bracket, which is fixedly installed on a positioning seat, and one end of the bracket extends to the rear end of the divider.

The spacing adjustment component is a double-headed cylinder or a double-headed hydraulic shaft, and the two positioning buckles are respectively installed on the telescopic shafts at both ends of the spacing adjustment component.

[0013] Preferably, the divider includes two dividing plates, which are arranged in a V-shape and are rotatably connected by a hinge. A slider is fixedly installed on the upper end of each of the two dividing plates, and a limiting guide groove is provided on the positioning seat that can slide and engage with the slider. The two dividing plates are movably connected to two positioning buckles via movable connectors, so that when the two positioning buckles are extended or retracted, they can drive the two dividing plates to move and retract or move and expand, thereby adjusting the expansion range of the divider.

[0014] Preferably, the movable connector includes a connecting guide groove, which is disposed on the outer wall of the dividing plate. A limiting connecting block is slidably installed in the connecting guide groove, and the inner end of the limiting connecting block is rotatably connected to a corresponding positioning buckle through a connecting shaft.

[0015] This invention also discloses a method for applying fertilizer to promote sprouting during the regeneration season of ratooning rice, the specific steps of which are as follows: The walking section moves the dividing section and the fertilizing section within the paddy field; Based on the row spacing of the ratooning rice in the paddy field, the spacing between adjacent dividers is adjusted by the spacing adjustment unit so that each divider is located exactly between two adjacent rows of rice plants. At the same time, adjust the spacing between the two feeding and fertilizing units in the feeding and fertilizing assembly so that the two feeding and fertilizing units can be located on one side of the two rows of rice plants respectively; During the forward movement of the divider, the two rows of rice plants are separated to the sides. The fertilizer storage section transports the fertilizer through the fertilizer conveying section to the two dispensing fertilizer units in the dispensing fertilizer assembly. The two dispensing fertilizer units then dispense the fertilizer to the roots of the two rows of rice ears.

[0016] The present invention has the following beneficial effects: 1. In this invention, a dividing section is provided on the fertilization equipment. During fertilization, multiple dividing devices within the dividing section are inserted between corresponding rows of rice plants. This allows the dividing devices to separate the two rows of rice plants to the sides as they move forward. Then, the fertilizer-discharging component discharging fertilizer from the rear of the dividing section prevents fertilizer from falling onto the rice ears. This not only prevents burning of the rice plants but also ensures that the fertilizer is accurately applied to the paddy soil, improving the fertilization effect. Furthermore, each fertilizer-discharging component corresponding to a dividing device has two fertilizer-discharging units. After the dividing device separates the rice plants, the two fertilizer-discharging units apply fertilizer along the two rows of rice plants respectively. This increases the fertilization range and efficiency of the fertilizer-discharging component, reduces the number of dividing devices and fertilizer-discharging components, and thus reduces damage to the rice plants caused by the dividing devices during fertilization.

[0017] 2. In this invention, the spacing between adjacent dividers can be adjusted by the spacing adjustment unit, so that each divider is positioned exactly between the corresponding two rows of rice plants, thereby improving the dividing effect of the dividers and preventing the rice plants from being damaged by collision when the dividers move. Furthermore, by adjusting the position of the dividers, two dividers in the dividing section can be positioned in front of the traveling wheels on both sides of the traveling section, so that the traveling wheels can move along the path after dividing the rice plants, preventing the traveling wheels from crushing the rice plants when they move, and further reducing the damage to the rice plants during fertilization.

[0018] 3. In this invention, the spacing between the two fertilizer application units can be adjusted according to the rice row spacing via a spacing adjustment component, so that the two fertilizer application units can respectively apply fertilizer to one side of the two rice rows, thereby improving the fertilization effect. Moreover, when adjusting the spacing between the two fertilizer application units, the spacing adjustment component can drive the two dividing plates in the two dividers to move and contract or move and expand, thereby adjusting the expansion range of the dividers so that the expansion range of the dividers is adapted to the rice row spacing and the spacing between the two fertilizer application units, thereby improving the dividing effect of the dividers and the fertilizer application effect, while preventing the dividers from being too small to achieve the corresponding dividing effect, or the dividers from being too large to cause excessive dividing of the rice plants and damage.

[0019] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0025] Example 1 Please see Figures 1-4As shown, this embodiment is a fertilization device, including a walking section 1, a dividing section 2, and a fertilization section 3. The walking section 1 can drive the dividing section 2 and the fertilization section 3 to move. The dividing section 2 can push the crops to both sides when moving, and the fertilization section 3 can fertilize within the gaps between the crops pushed by the dividing section 2. The dividing section 2 includes a spacing adjustment section and multiple dividing heads 22. The spacing adjustment section can simultaneously drive the multiple dividing heads 22 to move and spread or move and retract to adjust the spacing between adjacent dividing heads 22. The fertilization section 3 includes a fertilizer storage section, a fertilizer conveying section, and multiple discharging fertilization components. Each discharging fertilization component is equipped with... There are two feeding and fertilizing units, which are respectively located on both sides of the rear end of the corresponding divider 22. The feeding and fertilizing units are connected to the fertilizer storage unit through the fertilizer conveying unit, so that the fertilizer storage unit can convey fertilizer to each feeding and fertilizing unit through the fertilizer conveying unit. The two feeding and fertilizing units in the feeding and fertilizing assembly can move and expand to both sides when the divider 22 moves and expands, so that the distance between the two feeding and fertilizing units moves and increases. The two feeding and fertilizing units in the feeding and fertilizing assembly can also move and close inward when the divider 22 moves and contracts, so that the distance between the two feeding and fertilizing units moves and decreases. When promoting budding and applying fertilizer during the ratooning season of ratooning rice, the walking unit 1 drives the dividing unit 2 and the fertilizing unit 3 to move and walk in the paddy field; and according to the row spacing of ratooning rice in the paddy field, the spacing adjustment unit adjusts the spacing between adjacent dividing units 22 so that each dividing unit 22 is located exactly between two adjacent rows of rice plants; at the same time, the spacing between the two dispensing fertilization units in the dispensing fertilization component is adjusted so that the two dispensing fertilization units are located on one side of the two rows of rice plants respectively; as the dividing unit 22 moves forward, it separates the two rows of rice plants to the sides, and the fertilizer storage unit delivers fertilizer to the two dispensing fertilization units in the dispensing fertilization component through the fertilizer conveying unit, and the two dispensing fertilization units deliver the fertilizer to the vicinity of the roots of the two rows of rice ears respectively; By separating the rice grains with the divider 22 before fertilizing, fertilizer can be prevented from falling onto the rice ears during fertilization. This not only prevents the rice seedlings from being burned, but also ensures that the fertilizer is accurately applied to the paddy field soil, thereby improving the fertilization effect. Furthermore, each fertilization component corresponding to the divider 22 is equipped with two fertilization units. After the rice grains are separated by the divider 22, the two fertilization units apply fertilizer along the two rows of rice grains respectively. This increases the fertilization range and efficiency of the fertilization component, reduces the number of dividers 22 and fertilization components, and thus reduces the damage to the rice grains caused by the divider 22 during fertilization. The spacing between adjacent dividers 22 is adjusted by the spacing adjustment section so that each divider 22 is positioned exactly between the corresponding two rows of rice plants, thereby improving the dividing effect of the dividers 22 and preventing the rice plants from being damaged by collision when the dividers 22 move. Furthermore, by adjusting the position of the dividers 22, two dividers 22 in the dividing section are positioned in front of the traveling wheels on both sides of the traveling section 1, so that the traveling wheels can move along the path after dividing the rice plants, preventing the traveling wheels from crushing the rice plants when they move, and further reducing the damage to the rice plants during fertilization. Furthermore, the walking unit 1 is a high-clearance self-propelled plant protection vehicle. The high-clearance self-propelled plant protection vehicle adopts a high chassis and narrow walking wheels, which can prevent the chassis and walking wheels from crushing rice plants during the mobile fertilization process. The high-clearance self-propelled plant protection vehicle is also equipped with an intelligent controller that is connected to the dividing unit 2 and the fertilization unit 3 to realize the intelligent automatic control of the fertilization equipment.

[0026] Example 2 Please see Figures 1-3 , Figure 10 , Figure 12 As shown, the difference between this embodiment and the above embodiment is that the spacing adjustment part includes an adjustment drive unit and a positioning frame 21. The positioning frame 21 is fixedly installed on the walking part 1. Multiple sets of limiting guide shafts 23 are fixedly installed inside the positioning frame 21, and multiple adjustment seats 24 that slide with the limiting guide shafts 23 are installed on the positioning frame 21. A positioning seat 25 is fixedly installed on the adjustment seat 24. A diverter 22 that is inclined downward is installed on the front side of the positioning seat 25. The adjustment drive unit can drive multiple adjustment seats 24 to move and spread or move and contract along the limiting guide shafts 23. At the same time, the adjustment seats 24 drive the diverter 22 to move synchronously to adjust the spacing between adjacent diverters 22. During the adjustment process, multiple diverters 22 always maintain an equidistant distribution. Thus, through the cooperation of the limiting guide shaft 23, the adjusting seat 24 and the adjusting drive unit, the equidistant telescopic adjustment of multiple dividers 22 can be realized, thereby enabling the rapid adjustment of the dividers 22 so that the spacing between the dividers 22 matches the spacing between rice rows, thereby improving the fertilization effect of dividing the rice.

[0027] Specifically, the adjustment drive unit includes an adjustment plate 26 and a lifting drive component 27. The adjustment plate 26 is located on one side of the positioning frame 21. The adjustment plate 26 is provided with multiple guide adjustment slots 29 that correspond one-to-one with the adjustment seat 24. Each adjustment seat 24 is fixedly installed with a guide adjustment rod 28 that can slide and engage in the corresponding guide adjustment slot 29. The lifting drive component 27 can drive the adjustment plate 26 to move up and down relative to the positioning frame 21. When the adjustment plate 26 moves up and down relative to the positioning frame 21, the adjustment plate 26 can drive multiple guide adjustment rods 28 to move synchronously to retract or extend synchronously through the multiple guide adjustment slots 29 on it, so as to adjust the distance between adjacent guide adjustment rods 28. The multiple guide adjustment rods 28 are equidistantly distributed when they retract or extend. The lifting drive component 27 is a cylinder, a hydraulic telescopic shaft, or an electric telescopic shaft. The lifting drive component 27 is fixedly installed on the walking part 1, and the telescopic end of the lifting drive component 27 is fixedly connected to the adjusting plate 26. The upper and lower ends of the adjacent guide adjustment grooves 29 are equidistantly distributed, and there is a gap between the upper ends of the adjacent guide adjustment grooves 29 and the lower ends of the adjacent guide adjustment grooves 29.

[0028] In this embodiment, taking the example that the distance between the upper ends of adjacent guide adjustment grooves 29 is smaller than the distance between the lower ends of adjacent guide adjustment grooves 29, when the lifting drive component 27 drives the adjustment plate 26 to move upward relative to the positioning frame 21, the adjustment plate 26 drives multiple guide adjustment rods 28 to move and spread to both ends through the guide adjustment grooves 29, thereby gradually increasing the distance between adjacent guide adjustment rods 28. At the same time, the guide adjustment rods 28 drive the adjustment seat 24 and the divider 22 to move and adjust synchronously, so that the distance between adjacent dividers 22 moves and increases. When the lifting drive 27 drives the adjusting plate 26 to move downward relative to the positioning frame 21, the adjusting plate 26 drives multiple guide adjusting rods 28 to move and retract towards the center through the guide adjusting groove 29, thereby gradually reducing the distance between adjacent guide adjusting rods 28. At the same time, the guide adjusting rods 28 drive the adjusting seat 24 and the divider 22 to move and adjust synchronously, so as to reduce the distance between adjacent dividers 22.

[0029] Furthermore, the positioning seat 25 is locked and fixedly installed on the adjusting seat 24 by an adjustable connector. The adjustable connector can drive the positioning seat 25 to move left and right along the adjusting seat 24 to adjust the installation position of the positioning seat 25 and the divider 22 on the adjusting seat 24. The adjustable connector includes a side plate 211 and a fastening bolt 213. The side plate 211 is fixedly installed on one side of the positioning seat 25. The side plate 211 is provided with a strip-shaped connecting groove 212. The fastening bolt 213 can pass through the strip-shaped connecting groove 212 and be tightened and installed on the adjusting seat 24. By loosening the fastening bolt 213, the positioning seat 25 and the side plate 211 can be adjusted left and right on the adjusting seat 24. This allows for fine-tuning of the positions of the positioning seat 25 and the divider 22 according to the actual distribution of rice plants in the paddy field. This ensures that the divider 22 is positioned precisely between two rows of rice plants, improving the fertilization effect. Furthermore, the position of the divider 22 can be fine-tuned according to the position of the traveling wheels on both sides of the traveling unit 1, ensuring that the divider 22 is positioned directly in front of the traveling wheels. This improves the division effect of the rice plants on the front side and prevents the traveling wheels from damaging the rice plants.

[0030] Example 3 Please see Figures 3-9 As shown, the difference between this embodiment and the above embodiment is that the fertilizer storage section includes a fertilizer box 31, which is fixedly installed on the walking section 1, and a material drop trough 35 is provided at the bottom of the fertilizer box 31. The fertilizer conveying unit includes an outer protective cylinder 36, which is connected and installed below the discharge chute 35. The bottom end of the outer protective cylinder 36 is connected and installed with multiple discharge hoppers 39 that are connected one-to-one with the discharge fertilization components. A rotary feeding unit is rotatably installed inside the outer protective cylinder 36. The rotary feeding unit can reciprocate to receive the fertilizer falling from the discharge chute 35 during rotation and convey the collected fertilizer to each discharge hopper 39 below. The fertilizer in the discharge hopper 39 is then discharged and fertilized by the discharge fertilization components. A partition 310 is also fixedly installed inside the hopper 39. The partition 310 divides the hopper 39 into two discharge chambers, which are respectively connected to two discharge fertilization units in the discharge fertilization assembly. The rotary feeding unit includes a rotary drive and a discharge roller 37. The discharge roller 37 is rotatably mounted inside the outer protective cylinder 36. The outer ring of the discharge roller 37 is provided with multiple fertilizer conveying grooves 38. The rotary drive can drive the discharge roller 37 to rotate continuously, so that the fertilizer conveying grooves 38 on the discharge roller 37 reciprocate between the discharge groove 35 and the discharge hopper 39. The rotary drive includes a motor 32, which is connected to one end of the discharge roller 37. During fertilization, the motor 32 drives the discharge roller 37 to rotate continuously, which in turn drives the fertilizer conveying trough 38 on the outer ring of the discharge roller 37 to make a circular motion. When the fertilizer conveying trough 38 rotates to the bottom of the discharge trough 35, the fertilizer in the fertilizer box 31 can fall into the fertilizer conveying trough 38 through the discharge trough 35. Then, when the fertilizer conveying trough 38 moves above the discharge hopper 39, the fertilizer in the fertilizer conveying trough 38 is discharged and conveyed to each discharge hopper 39, and then conveyed to the corresponding discharge fertilization unit by the two discharge chambers inside the discharge hopper 39. Finally, the discharge fertilization unit performs the discharge fertilization.

[0031] Example 4 Please see Figure 4 , Figure 5 , Figure 10 , Figure 11 As shown, the difference between this embodiment and the above embodiment is that the feeding and fertilizing component includes a bracket 311, which is fixedly installed on the positioning seat 25. One end of the bracket 311 extends to the rear end of the divider 22. A spacing adjustment component 312 is fixedly installed at the end of the bracket 311. Positioning buckles 313 are installed at both ends of the spacing adjustment component 312. The spacing adjustment component can adjust the distance between the two positioning buckles 313. A fertilizer head 34 is fixedly installed in each of the two positioning buckles 313. A fertilizer conduit 33 is connected to the upper end of the fertilizer head 34. One end of the fertilizer conduit 33 is connected to the fertilizer conveying part. The spacing adjustment component 312 is a double-headed cylinder or a double-headed hydraulic shaft, and the two positioning buckles 313 are respectively installed on the telescopic shafts at both ends of the spacing adjustment component 312.

[0032] The spacing adjustment component 312 can adjust the distance between the two positioning buckles 313 by extending and retracting at both ends, thereby adjusting the distance between the two fertilizer heads 34. This allows the two fertilizer heads 34 to be positioned on one side of the two rows of rice plants. During fertilization, the fertilizer in the hopper 39 is delivered to the corresponding fertilizer head 34 through the fertilizer guide tube 33, and finally delivered to one side of the rice plant by the fertilizer head 34. This achieves precise positioning of the fertilizer and improves the fertilization effect.

[0033] Example 5 Please see Figures 10-15 As shown, the difference between this embodiment and the above embodiment is that the divider 22 includes two dividing plates 2201, which are arranged in a V-shape and are rotatably connected by a hinge. A slider 2204 is fixedly installed on the upper end of each of the two dividing plates 2201, and a limiting guide groove 210 is provided on the positioning seat 25 that can slide and engage with the slider 2204. The two dividing plates 2201 are movably connected to the two positioning buckles 313 respectively through the movable connectors, so that when the two positioning buckles 313 are extended or retracted, they can drive the two dividing plates 2201 to move and retract or move and unfold, so as to adjust the unfolding range of the divider 22. The movable connector includes a connecting guide groove 2202, which is disposed on the outer wall of the dividing plate 2201. A limiting connecting block 2203 is slidably installed in the connecting guide groove 2202. The inner end of the limiting connecting block 2203 is rotatably connected to the corresponding positioning buckle 313 through a connecting shaft.

[0034] The two fertilizer heads 34 are located at the rear edge of the two dividing plates 2201, thus protecting the fertilizer heads 34 from contact with and interference by the rice plants. When the two positioning buckles 313 move to adjust the distance between the two fertilizer heads 34, the two positioning buckles 313, through the cooperation of the connecting guide groove 2202 and the limiting connecting block 2203, drive the two dividing plates 2201 to move and retract or move and unfold, thereby adjusting the unfolding range of the divider 22. This not only makes the unfolding range of the divider 22 match the spacing between the rice rows, thereby improving the dividing effect of the divider 22, but also ensures that the two dividing plates 2201 are always located in front of the two fertilizer heads 34, protecting the fertilizer heads 34.

[0035] Example 6 This embodiment discloses a method for applying fertilizer to promote sprouting during the regeneration season of ratooning rice. The specific steps are as follows: The walking section 1 drives the dividing section 2 and the fertilizing section 3 to move and walk in the paddy field; Based on the row spacing of the ratooning rice in the paddy field, the spacing between adjacent dividers 22 is adjusted by the spacing adjustment unit so that each divider 22 is located exactly between two adjacent rows of rice plants.
