Description

Technical Field

[0001] This invention relates to a fertilizer application control device and application method, and relates to the field of fertilizer application technology. Background Technology

[0002] Modern agriculture refers to agriculture developed on the basis of traditional agriculture using modern industry and science and technology, achieving high economic, ecological, and social benefits. Fertilizer application devices are important tools in modern agriculture for improving fertilization efficiency and precision, playing a significant role in increasing agricultural production efficiency, conserving resources, and reducing the environmental impact of improper fertilization methods.

[0003] In existing fertilization equipment technology, fertilizer application devices are generally installed on mobile vehicles. The mobile vehicles move the fertilizer application devices to various fertilization sites. After completing the application of fertilizer on one fertilization route, the device moves to another fertilization route to continue applying fertilizer. This single-path fertilization method cannot simultaneously meet the fertilization needs on both sides of the fertilization route, resulting in low efficiency of fertilizer application. Summary of the Invention

[0004] This invention provides a high-efficiency fertilizer application control device and application method to overcome the shortcomings of existing fertilizer application devices that cannot simultaneously meet the fertilization needs of both sides of the fertilization line, resulting in low fertilizer application efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] This invention discloses a high-efficiency fertilizer application control device, comprising two fertilizer application mechanisms connected by a spacing adjustment mechanism and arranged opposite to each other. Each fertilizer application mechanism includes a reset control component, a material guide component slidably disposed on the reset control component, a lifting linkage component connected above the material guide component, a fertilizer storage component disposed on the lifting linkage component, the fertilizer storage component being located on top of the material guide component, a rotating material feeding component coaxially disposed inside the fertilizer storage component, and a gravity transfer component coaxially disposed inside the material guide component.

[0007] Furthermore, the material guiding assembly includes a hollow material guiding tray, a fertilizer application tube fixedly installed at the bottom of the hollow material guiding tray and connected to it, a first mounting bracket fixedly installed at the top of the hollow material guiding tray, a first support member fixedly installed on the periphery of the fertilizer application tube, a second support member slidably sleeved on the periphery of the fertilizer application tube, the first support member and the second support member being connected by a first elastic member, a second mounting bracket fixedly installed on the periphery of the hollow material guiding tray, a second elastic member being installed inside the second mounting bracket, a third magnetic plate slidably installed inside the second mounting bracket being connected to the second elastic member, a locking rod fixedly installed on the surface of the third magnetic plate penetrating into the interior of the hollow material guiding tray, a central opening communicating with the interior of the hollow material guiding tray being opened on one side of the hollow material guiding tray, and a limiting protrusion being provided inside the hollow material guiding tray.

[0008] Furthermore, the gravity transfer assembly includes a central isolation plate coaxially rotatably disposed inside the hollow guide plate. An arc-shaped sealing frame and a fertilizer separator are fixedly disposed on the periphery of the central isolation plate. An arc-shaped transfer cavity is disposed between the arc-shaped sealing frame and the fertilizer separator. A positioning element is fixedly disposed on the surface of the fertilizer separator. A notch is opened on the periphery of the arc-shaped sealing frame. A guide control gear that rotates with the central opening is fixedly disposed on the surface of the central isolation plate.

[0009] Furthermore, the spacing adjustment mechanism includes a support frame, on which a support shaft is fixedly mounted. The support shaft is connected to one end of two fixed plates. A bidirectional screw is rotatably arranged between the two fixed plates. A support rod is slidably arranged at the other end of the fixed plates. One end of the support rod is fixedly mounted on a hollow guide plate, and the other end is fixedly provided with a moving part that is threadedly engaged with the bidirectional screw.

[0010] Furthermore, the fertilizer storage assembly includes a fertilizer storage box, inside which a hollow discharge body coaxially with the fertilizer storage box is fixedly installed. A discharge pipe connected to the hollow discharge body is fixedly installed at the bottom of the fertilizer storage box. The hollow discharge body and the discharge pipe form a central discharge channel. Several curved mounting ports are opened on the periphery of the hollow discharge body near the bottom. Gear mounting ports corresponding to the curved mounting ports are opened on the periphery of the hollow discharge body near the top. The gear mounting ports and the corresponding curved mounting ports are connected through a shaft mounting cavity. The fertilizer storage assembly is equipped with a central rotating feeding component for feeding the fertilizer inside the fertilizer storage assembly into the central discharge channel. The central discharge channel is connected to a guiding component.

[0011] Furthermore, the rotating feeding assembly includes feeding control shafts that correspond one-to-one with the shaft mounting cavities. Lateral gears located inside the gear mounting openings are fixedly arranged on the circumferential side of the feeding control shaft. Multiple feeding control plates located inside the curved mounting openings are arranged in a circumferential array on the circumferential side of the feeding control shaft. A central gear is arranged inside the hollow discharge body. The central gear meshes with each of the lateral gears on its circumference. A support ring is fixed to the top of the central gear.

[0012] Furthermore, the reset control component includes a vibrating tube that slides inside the fertilizer application tube, a third support is fixedly provided on the periphery of the vibrating tube, a reset control component is fixedly provided on the top of the third support, and the reset control component slides in conjunction with a U-shaped limiting seat provided on the surface of the hollow guide plate.

[0013] Furthermore, the lifting linkage assembly includes a lifting shaft, a radial connecting plate fixedly installed at the top of the lifting shaft, a lifting control shaft fixedly installed at the bottom of the radial connecting plate, a spiral groove opened on the circumferential side of the lifting control shaft, a first magnetic plate fixedly installed on the circumferential side of the fertilizer storage box and slidingly engaged with the lifting shaft, a second magnetic plate fixedly installed on the circumferential side of the lifting shaft, and a linkage plate fixedly installed at the bottom of the lifting shaft.

[0014] An application method for a high-efficiency fertilizer application control device includes the following steps:

[0015] S01. Rotate the bidirectional screw to adjust the horizontal distance between the two fertilizer application mechanisms that are set up opposite to each other, through the threaded engagement between the bidirectional screw and the two moving parts.

[0016] S02. Move the fertilizer application mechanism to a fertilizer application point by moving the vehicle body, control the second electromagnet on the second mounting frame to de-energize and demagnetize, and under the action of the elastic restoring force of the second elastic element, make the locking rod disengage from the positioning element.

[0017] S03. The elastic restoring force of the first elastic element is used to move the reset control element downward to reset. During this process, the reset control element drives the guide control gear to rotate counterclockwise, so that the arc-shaped transfer cavity returns to the position of the discharge pipe. At the same time, the lifting control shaft that moves down synchronously with the reset control element drives the central gear to rotate. The feeding control shaft that rotates synchronously with the central gear drives the feeding control plates in each direction to rotate synchronously, so that a certain amount of fertilizer is fed into the hollow discharge body.

[0018] S04. The granular fertilizer that has been pushed into the hollow discharge body falls directly into the arc-shaped transfer cavity along the discharge pipe. Then, under the gravity of the fertilizer itself, the fertilizer separator plate rotates clockwise. The upward lifting control shaft drives the central gear to rotate again, so that a certain amount of fertilizer is pushed into the hollow discharge body. When the arc-shaped sealing frame rotates to the discharge pipe, the discharge pipe is sealed. At this time, no more fertilizer enters the arc-shaped transfer cavity. The second magnetic plate moves upward into the magnetic range of the first magnetic plate. Under the action of magnetic attraction, the fertilizer separator plate continues to rotate clockwise until it abuts against the limiting protrusion.

[0019] S05. When the fertilizer separator plate rotates to abut against the limit protrusion, the positioning component just rotates to the position of the locking rod. The second electromagnet on the second mounting bracket is energized and magnetized. Under the action of magnetic repulsion, the third magnetic plate is driven to move and compress the second elastic component, so that the locking rod is inserted into the positioning component. At this time, the arc-shaped transfer cavity is aligned with the fertilizer application tube.

[0020] S06. Under the influence of gravity, the fertilizer slides down into the fertilizer application tube and falls into the fertilizer pit, thus realizing the fertilizer application operation. After all the fertilizer in the arc-shaped transfer chamber is unloaded, the steps S02 to S06 are repeated to realize the fertilization operation at the next fertilization point. Continuous fertilization operation can be realized in the above way.

[0021] The beneficial effects achieved by this invention are as follows: The elastic restoring force of the first elastic element causes the reset control element to move downwards and reset. During this process, the reset control element drives the guide control gear to rotate counterclockwise, causing the arc-shaped transfer cavity to return to the discharge pipe position. Simultaneously, the lifting control shaft, which moves downwards synchronously with the reset control element, drives the central gear to rotate. The feeding control shaft, which rotates synchronously with the central gear, drives the feeding control plates in various directions to rotate synchronously, causing a certain amount of fertilizer to be fed into the hollow discharge body. The granular fertilizer fed into the hollow discharge body falls directly into the arc-shaped transfer cavity along the discharge pipe. Subsequently, under the weight of the fertilizer itself, the fertilizer separator plate rotates clockwise. During this process, the lifting control shaft moves upwards, driving the central gear to rotate again, causing a certain amount of fertilizer to be fed into the hollow discharge body. This enables automated quantitative replenishment of fertilizer in the arc-shaped transfer cavity during fertilizer application, improving the efficiency of fertilizer application.

[0022] In this invention, when the fertilizer separator plate rotates to abut against the limiting protrusion, the positioning member rotates to the locking rod position. The second electromagnet on the second mounting frame is energized and magnetized. Under the action of magnetic repulsion, the third magnetic plate moves and compresses the second elastic member, thereby allowing the locking rod to be inserted into the positioning member. This confines the arc-shaped transfer cavity to the fertilizer application tube, ensuring that all fertilizer in the arc-shaped transfer cavity can be unloaded. After all fertilizer in the arc-shaped transfer cavity has been unloaded, the second electromagnet on the second mounting frame is de-energized and demagnetized. Under the action of the elastic restoring force of the second elastic member, the locking rod disengages from the positioning member, thus enabling continuous fertilization operations.

[0023] In this invention, during the clockwise rotation of the arc-shaped transfer cavity, the rotating guide gear drives the reset control component to move upward. During this process, the vibrating tube moves upward along the inside of the fertilizer application tube. The second support component, which moves synchronously with the reset control component, moves upward to compress the first elastic component. After all the fertilizer in the arc-shaped transfer cavity is unloaded and the locking rod is released from its position, the elastic restoring force of the first elastic component causes the reset control component to move downward to reset. During this process, the vibrating tube moves downward along the inside of the fertilizer application tube. This achieves vibration of the inside of the fertilizer application tube during the unloading process, ensuring that the fertilizer in the fertilizer application tube will not clog the tube due to sticky adhesion.

[0037] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0038] Example 1

[0039] like Figures 1-11 As shown, a high-efficiency fertilizer application control device includes two fertilizer application mechanisms 1 connected by a spacing adjustment mechanism 8 and arranged opposite to each other. Each fertilizer application mechanism 1 includes a reset control component 6, on which a material guide component 4 is slidably disposed, and above which a lifting linkage component 7 is connected. The lifting linkage component 7 is provided with a fertilizer storage component 2, which is located on top of the material guide component 4. A rotating material feeding component 3 is rotatably disposed inside the fertilizer storage component 2 and is coaxial with it. A gravity transfer component 5 is rotatably disposed inside the material guide component 4 and is coaxial with it.

[0040] The material guiding assembly 4 includes a hollow material guiding plate 402, a discharge pipe 203 fixedly installed on the top of the hollow material guiding plate 402 and connected to it, a fertilizer application pipe 401 fixedly installed on the bottom of the hollow material guiding plate 402 and connected to it, a first mounting bracket 403 fixedly installed on the top of the hollow material guiding plate 402, a fertilizer storage box 201 fixedly installed on the top of the first mounting bracket 403, a first support member 404 fixedly installed on the periphery of the fertilizer application pipe 401, and a second support member 405 slidably sleeved on the periphery of the fertilizer application pipe 401. The first support member 404 and the second support member 405 are connected. Component 405 is connected by a first elastic member 406. A second mounting bracket 407 is fixedly provided on the periphery of the hollow guide plate 402. A second elastic member 408 is provided inside the second mounting bracket 407. A third magnetic plate 409 is slidably provided inside the second mounting bracket 407 and connected to the second elastic member 408. A locking rod 410 is fixedly provided on the surface of the third magnetic plate 409 and extends into the interior of the hollow guide plate 402. A central opening 411 communicating with the interior of the hollow guide plate 402 is provided on one side of the hollow guide plate 402. A limiting protrusion 412 is provided inside the hollow guide plate 402.

[0041] The gravity transfer assembly 5 includes a central isolation plate 502 coaxially rotatably disposed inside the hollow guide plate 402. An arc-shaped sealing frame 503 and a fertilizer separator plate 504 are fixedly disposed on the periphery of the central isolation plate 502. An arc-shaped transfer cavity 501 is disposed between the arc-shaped sealing frame 503 and the fertilizer separator plate 504. A positioning element 505 is fixedly disposed on the surface of the fertilizer separator plate 504. A notch 506 is opened on the periphery of the arc-shaped sealing frame 503. A guide control gear 507 that rotates with the central opening 411 is fixedly disposed on the surface of the central isolation plate 502.

[0042] The spacing adjustment mechanism 8 includes a support frame 801, on which a support shaft 802 is fixedly mounted. The support shaft 802 is connected to one end of two fixed plates 803. A bidirectional screw 804 is rotatably arranged between the two fixed plates 803. A support rod 805 is slidably arranged at the other end of the fixed plate 803. One end of the support rod 805 is fixedly mounted on the hollow guide plate 402, and the other end is fixedly provided with a moving part 806 that is threadedly engaged with the bidirectional screw 804.

[0043] By rotating the bidirectional screw 804, the horizontal distance between the two support rods 805 can be adjusted through the threaded engagement between the bidirectional screw 804 and the two moving parts 806, thereby enabling the distance between the two fertilizer application mechanisms 1 to meet the simultaneous fertilization operation of the two fertilization lines.

[0044] The reset control component 6 is slidably mounted on the material guiding component 4. The reset control component 6 is engaged with the gravity transfer component 5. The reset control component 6 achieves downward reset through the action of elastic force. After the reset control component 6 drives the gravity transfer component 5 to rotate in the opposite direction and reset, the arc-shaped transfer cavity 501 is connected to the central discharge channel. The lifting linkage component 7 is installed on the peripheral side of the fertilizer storage component 2 and is fixedly installed on the top of the reset control component 6. The lifting linkage component 7 is used to control the rotation of the rotating material feeding component 3. The lifting linkage component 7 includes a first magnetic plate 701 and a second magnetic plate 702 disposed below it. The first electromagnet installed at the bottom of the first magnetic plate 701 and the first permanent magnet installed at the top of the second magnetic plate 702 are magnetically attracted to each other.

[0045] When the fertilizer in the fertilizer storage component 2 enters the arc-shaped transfer cavity 501 inside the guide component 4 along the central discharge channel, the gravity transfer component 5 rotates clockwise under the gravity of the fertilizer until the arc-shaped transfer cavity 501 is connected to the fertilizer application tube 401. The first electromagnet is energized and magnetized, so that the second magnetic plate 702 is attracted and fixed at the bottom of the first magnetic plate 701. The fertilizer in the arc-shaped transfer cavity 501 is discharged along the fertilizer application tube 401. After a single fertilizer application is completed, the first electromagnet is de-energized and demagnetized to reset the arc-shaped transfer cavity 501. During this process, the input of fertilizer in the central discharge channel is completed by rotating the rotating feeding component 3.

[0046] The fertilizer storage assembly 2 includes a fertilizer storage box 201. A hollow discharge body 202, coaxial with the fertilizer storage box 201, is fixedly installed inside the fertilizer storage box 201. A discharge pipe 203, connected to the hollow discharge body 202, is fixedly installed at the bottom of the fertilizer storage box 201. The hollow discharge body 202 and the discharge pipe 203 form a central discharge channel. Several curved mounting ports 204 are opened on the periphery of the hollow discharge body 202 near the bottom. Gear mounting ports 205, corresponding to the curved mounting ports 204, are opened on the periphery of the hollow discharge body 202 near the top. The gear mounting ports 205 and the corresponding curved mounting ports 204 are connected through a shaft mounting cavity 206. The fertilizer storage assembly 2 is equipped with a central rotating feeding component 3 for feeding fertilizer from inside the fertilizer storage assembly 2 into the central discharge channel. The central discharge channel is connected to the guiding component 4.

[0047] The rotary feeding assembly 3 includes feeding control shafts 301 corresponding to the shaft mounting cavities 206. The feeding control shafts 301 are rotatably mounted inside the corresponding shaft mounting cavities 206. Lateral gears 302 are fixedly mounted on the circumferential side of the feeding control shafts 301, located inside the gear mounting openings 205. Multiple feeding control plates 303 are arranged in a circumferential array on the circumferential side of the feeding control shafts 301, located inside the curved mounting openings 204. When the feeding control shafts 301 are rotated, the rotation of the feeding control plates 303 can be used to feed the material. The granular fertilizer in the fertilizer storage box 201 is fed into the hollow discharge body 202 through the curved mounting port 204. A central gear 304 is installed inside the hollow discharge body 202. The central gear 304 meshes with each of the lateral gears 302 around it. The support ring 305 fixed on the top of the central gear 304 is rotatably set inside the top of the hollow discharge body 202. By controlling the rotation of the central gear 304, the lateral gears 302 can be rotated synchronously, thereby realizing the synchronous rotation of each feeding control shaft 301.

[0048] The lifting linkage assembly 7 includes a lifting shaft 703, a radial connecting plate 704 fixedly mounted on the top of the lifting shaft 703, a lifting control shaft 705 fixedly mounted on the bottom of the radial connecting plate 704, a spiral groove 706 opened on the circumferential side of the lifting control shaft 705, and a limiting member fixed to the inner wall of the central gear 304 slidingly engaged inside the spiral groove 706. Through this structural design, when the lifting shaft 703 is controlled to move up and down, the lifting control shaft 705 can drive the central gear 304 to move in the forward and reverse directions, thereby realizing the synchronous rotation between the material feeding control plates 303 on each material feeding control shaft 301. The first magnetic plate 701 is fixedly mounted on the circumferential side of the fertilizer storage box 201 and slides in cooperation with the lifting shaft 703. The second magnetic plate 702 is fixedly mounted on the circumferential side of the lifting shaft 703. A linkage plate 707 is fixedly mounted on the bottom of the lifting shaft 703.

[0049] The arc-shaped sealing frame 503 is attached to the inner wall of the hollow guide plate 402 on its periphery, and the fertilizer separator plate 504 is slidably attached to the inner wall of the hollow guide plate 402 on its periphery. In the initial state, the arc-shaped transfer cavity 501 is located at the discharge pipe 203. The granular fertilizer that has been pushed into the hollow discharge body 202 falls directly into the arc-shaped transfer cavity 501 along the discharge pipe 203. Then, under the gravity of the fertilizer itself, the fertilizer separator plate 504 rotates clockwise. When the arc-shaped sealing frame 503 rotates to the discharge pipe 203, the discharge pipe 203 is blocked, and no more fertilizer enters the arc-shaped transfer cavity 501. During this process, the second magnetic plate 702 moves upward to the first magnetic plate 701. Within the magnetic field, under the action of magnetic attraction, the fertilizer separator 504 continues to rotate clockwise until it abuts against the limiting protrusion 412. At this time, the arc-shaped transfer cavity 501 is aligned with the fertilizer application tube 401. Under the action of gravity, the fertilizer slides down into the fertilizer application tube 401 and finally falls from the fertilizer application tube 401 into the fertilizer pit, thus realizing the fertilizer application operation. After all the fertilizer in the arc-shaped transfer cavity 501 is discharged, the arc-shaped transfer cavity 501 begins to rotate counterclockwise to complete the reset. The arc-shaped transfer cavity 501 returns to the position of the discharge tube 203. At this time, the fertilizer in the central discharge channel re-enters the arc-shaped transfer cavity 501. Continuous fertilization operation can be realized through the above method.

[0050] By setting the notch 506, during the rotation of the arc-shaped sealing frame 503, the locking rod 410 will not obstruct the rotation of the arc-shaped sealing frame 503. The second electromagnet installed inside the second mounting frame 407 is magnetically repelled by the second permanent magnet on the third magnetic plate 409. A central opening 411 connected to the interior of the hollow guide plate 402 is opened on one side. When the fertilizer separator plate 504 rotates to abut against the limiting protrusion 412, the positioning member 505 just rotates to the position of the locking rod 410, controlling the second electromagnet on the second mounting frame 407 to be energized and magnetized, under the magnetic repulsion force... Under the action of the third magnetic plate 409, the second elastic member 408 is moved and compressed, thereby causing the locking rod 410 to be inserted into the positioning member 505 (then the first electromagnet on the first magnetic plate 701 is de-energized and demagnetized). This limits the arc-shaped transfer cavity 501 to the fertilizer application tube 401, so as to ensure that all the fertilizer in the arc-shaped transfer cavity 501 can be unloaded. After all the fertilizer in the arc-shaped transfer cavity 501 is unloaded, the second electromagnet on the second mounting bracket 407 is de-energized and demagnetized. Under the action of the elastic restoring force of the second elastic member 408, the locking rod 410 is disengaged from the positioning member 505.

[0051] The reset control assembly 6 includes a vibrating tube 601 that slides inside the fertilizer application tube 401. A third support 602 is fixedly mounted on the periphery of the vibrating tube 601, and a reset control component 603 is fixedly mounted on the top of the third support 602. A first support 404 is slidably sleeved on the reset control component 603, and a second support 405 is fixedly mounted on the reset control component 603. The reset control component 603 meshes with a guide control gear 507. A U-shaped limiting seat 604 fixedly mounted on the surface of the hollow guide plate 402 slides in cooperation with the reset control component 603. A linkage plate 707 is fixedly mounted on the top of the reset control component 603. During the clockwise rotation of the arc-shaped transfer cavity 501, the rotating guide control gear 507 drives the reset control component 603 to rotate. The position control element 603 moves upward (during which the vibrating tube 601 moves upward along the inside of the fertilizer application tube 401). The second support element 405, which moves synchronously with the reset control element 603, moves upward to compress the first elastic element 406. After all the fertilizer in the arc-shaped transfer cavity 501 is unloaded and the locking rod 410 is released from limiting the position of the positioning element 505, the elastic restoring force of the first elastic element 406 causes the reset control element 603 to move downward to reset. During this process, the vibrating tube 601 moves downward along the inside of the fertilizer application tube 401. This allows for the vibration of the inside of the fertilizer application tube 401 during the unloading process, ensuring that the fertilizer in the fertilizer application tube 401 will not clog the fertilizer application tube 401 due to sticky adhesion.

[0052] An application method for a high-efficiency fertilizer application control device includes the following steps:

[0053] S01. Rotate the bidirectional screw 804. Under the threaded engagement between the bidirectional screw 804 and the two moving parts 806, the horizontal distance between the two fertilizer application mechanisms 1 set up opposite to each other can be adjusted.

[0054] S02. Move the fertilizer application mechanism 1 to a fertilizer application point by moving the vehicle body, control the second electromagnet on the second mounting frame 407 to de-energize and demagnetize, and under the action of the elastic restoring force of the second elastic element 408, make the locking rod 410 disengage from the positioning element 505.

[0055] S03. The first elastic element 406 is used to restore the elastic force of the first elastic element 406 to move the reset control element 603 downward to reset. During this process, the reset control element 603 drives the guide control gear 507 to rotate counterclockwise, so that the arc-shaped transfer cavity 501 returns to the position of the discharge pipe 203. At the same time, the lifting control shaft 705, which moves down synchronously with the reset control element 603, drives the central gear 304 to rotate. The feeding control shaft 301, which rotates synchronously with the central gear 304, drives the feeding control plates 303 in each direction to rotate synchronously, so that a certain amount of fertilizer is fed into the hollow discharge body 202.

[0056] S04. The granular fertilizer that has been pushed into the hollow discharge body 202 falls directly into the arc-shaped transfer cavity 501 along the discharge pipe 203. Then, under the gravity of the fertilizer itself, the fertilizer separator plate 504 rotates clockwise. During this process, the upward lifting control shaft 705 drives the central gear 304 to rotate again, so that a certain amount of fertilizer is pushed into the hollow discharge body 202. When the arc-shaped sealing frame 503 rotates to the discharge pipe 203, the discharge pipe 203 is sealed. At this time, no more fertilizer enters the arc-shaped transfer cavity 501. During this process, the second magnetic plate 702 moves upward into the magnetic range of the first magnetic plate 701. Under the action of magnetic attraction, the fertilizer separator plate 504 continues to rotate clockwise until it abuts against the limiting protrusion 412.

[0057] S05. When the fertilizer separator plate 504 rotates to abut against the limit protrusion 412, the positioning member 505 just rotates to the position of the locking rod 410. The second electromagnet on the second mounting bracket 407 is energized and magnetized.

S03. The elastic restoring force of the first elastic element is used to move the reset control element downward to reset. During this process, the reset control element drives the guide control gear to rotate counterclockwise, so that the arc-shaped transfer cavity returns to the position of the discharge pipe. At the same time, the lifting control shaft that moves down synchronously with the reset control element drives the central gear to rotate.

When the arc-shaped sealing frame rotates to the discharge pipe, the discharge pipe is sealed. At this time, no more fertilizer enters the arc-shaped transfer cavity. The second magnetic plate moves upward into the magnetic range of the first magnetic plate. Under the action of magnetic attraction, the fertilizer separator plate continues to rotate clockwise until it abuts against the limiting protrusion. S05. When the fertilizer separator plate rotates to abut against the limit protrusion, the positioning component just rotates to the position of the locking rod. The second electromagnet on the second mounting bracket is energized and magnetized.

At this time, the arc-shaped transfer cavity is aligned with the fertilizer application tube. S06. Under the influence of gravity, the fertilizer slides down into the fertilizer application tube and falls into the fertilizer pit, thus realizing the fertilizer application operation. After all the fertilizer in the arc-shaped transfer chamber is unloaded, the steps S02 to S06 are repeated to realize the fertilization operation at the next fertilization point. Continuous fertilization operation can be realized in the above way.
