Description

Technical Field

[0001] The invention relates to the technical field of water and fertilizer irrigation devices, and in particular to a water and fertilizer integrated automatic fertilizing device. Background Art

[0002] Integrated fertigation uses a pressure irrigation system to precisely and evenly deliver a blend of fertilizers to the soil around the crop's root zone. Applications require careful consideration of different crops, soil conditions, and growth stages, with irrigation water and fertilizer mixed in appropriate proportions before being delivered to the crop.

[0003] For example, Chinese patent publication number CN118923309A discloses a water and fertilizer irrigation mechanism for open-field planting of broccoli and a method of using the same, comprising a device main body, the device main body comprising: a base frame, a water and fertilizer tank is placed on the left end of the base frame, the top of the water and fertilizer tank is rotatably connected to a water and fertilizer cover by a hinge, and the top of the water and fertilizer cover is fixedly connected to a handle; by setting the water and fertilizer tank, an integrated water and fertilizer mixing container can play a role in diluting water and fertilizer, by setting a water pump, a first water pipe disc, a second water pipe disc, a water injection pipe and a venturi fertilizer applicator, starting the water pump, and pumping water from the irrigation channel near the target planting plot into the water and fertilizer tank, when the venturi fertilizer applicator does not open the valve, water can be directly pumped for irrigation, and by setting a fertilizer delivery pipe and a drip irrigation main pipe valve interface, it can be used to connect to the drip irrigation main pipe at the head of the target planting field, which is convenient for disassembly and installation, meets different irrigation methods, and effectively increases the practicality of the device.

[0004] This application uses the corresponding switches of the Venturi fertilizer applicator valve to achieve rapid fertilization of crops. When fertilizing, it is necessary to adjust multiple valves of pipelines such as the Venturi fertilizer applicator, water injection pipe and drip irrigation main pipe in sequence, and it is necessary to repeatedly adjust the above-mentioned multiple valves when resuming water irrigation after fertilization. The operating steps for the water irrigation delivery mode and the fertilizer liquid delivery mode are cumbersome and there is a possibility of misoperation, which in turn affects the effect of fertilization and has certain usage limitations.

[0005] Therefore, it is necessary to provide a water-fertilizer integrated automatic fertilizer adding device to solve the above technical problems. Summary of the Invention

[0006] The object of the present invention is to provide a water-fertilizer integrated automatic fertilizer adding device to solve the problems raised in the above background technology.

[0007] To achieve the above objectives, a water-fertilizer integrated automatic fertilizing device is designed, in which the pipeline components automatically cycle back and forth between the irrigation water delivery mode, the fertilizer and water mixing mode, and the fertilizer liquid delivery mode, thereby achieving automatic fertilization and ensuring the irrigation effect.

[0008] Based on the above ideas, the present invention provides the following technical solutions: a water-fertilizer integrated automatic fertilizing device, comprising a shell and a mixing drum fixedly installed in the shell, a pipeline assembly is provided inside the shell, the pipeline assembly includes a main pipe, an inlet pipe, an outlet pipe and three adjusting gears, the inlet pipe and the outlet pipe are connected to the mixing drum, and the main pipe, the inlet pipe and the outlet pipe are all provided with valves that rotate synchronously with the three adjusting gears, a control assembly for driving the three adjusting gears to rotate respectively is provided inside the shell, the control assembly includes a disc and a collar, and three first racks and three second racks are fixedly installed on the outer surface of the disc and the inner wall of the collar respectively; when the disc and the collar rotate, the adjusting gears can be driven to rotate through the first rack and the second rack, thereby realizing the switching of the corresponding valves.

[0009] As a further solution of the present invention: the pipeline assembly further includes a venturi tube connected to the water outlet pipe, and the main pipe is fixedly mounted on the shell and connected to both the water inlet pipe and the venturi tube.

[0010] As a further solution of the present invention: the end of the venturi tube close to the water inlet pipe is sealed, and the end away from the water inlet pipe is connected to the main pipe, and the valve on the main pipe is arranged between the water inlet pipe and the end of the venturi tube away from the water inlet pipe.

[0011] As a further solution of the present invention: the control component includes a motor fixedly mounted on the main pipe, a round rod fixedly mounted on the output shaft of the motor, the end of the round rod is fixedly connected to the disc, and a cross bar is fixedly mounted between the disc and the ring, and the three adjusting gears are all located between the disc and the ring and are arranged in a front-to-back staggered manner along the axial direction of the disc, and the adjusting gears, the first rack and the second rack are arranged in a one-to-one correspondence.

[0012] As a further solution of the present invention: the adjusting gear is divided into a first gear that rotates synchronously with the main valve, a second gear that rotates synchronously with the water inlet valve, and a third gear that rotates synchronously with the water outlet valve. The second gear is located between the first gear and the third gear, and the three first racks and the three second racks correspond to the first gear, the second gear, and the third gear, respectively.

[0013] As a further solution of the present invention: when the collar and the disc rotate, through the first rack and the second rack, only one of the main valve, the water inlet pipe valve and the water outlet pipe valve is opened, and the main valve, the water inlet pipe valve and the water outlet pipe valve are opened in sequence.

[0014] As a further solution of the present invention: a material box connected to the mixing drum is fixedly installed on the top of the shell, a support rod is rotatably installed on the surface of the mixing drum, a transmission connection is formed between the support rod and the round rod through a belt drive, and a material discharge assembly is jointly provided between the support rod and the material box.

[0015] As a further solution of the present invention: the unloading component is a groove wheel intermittently rotating unloading mechanism. When the round rod drives the disc and the ring to rotate one circle, the support rod intermittently rotates the unloading mechanism through the groove wheel to unload the material box once.

[0018] Compared with the existing technology, the beneficial effect of the present invention is that through the coordination between the main pipe, water inlet pipe, regulating gear and water outlet pipe, the pipeline components can automatically realize the cyclic switching between irrigation water delivery mode, fertilizer and water mixing mode and fertilizer liquid delivery mode, thereby realizing direct discharge of irrigation water, automatic mixing of fertilizer liquid, and automatic fertilization of crops, thereby ensuring the irrigation effect of crops.

[0019] When adding fertilizer, there is no need to repeatedly adjust the switch status of the main valve, water inlet pipe valve and water outlet pipe valve, which can not only meet the needs of efficient automation, but also effectively reduce the burden on workers and avoid the possibility of workers' misoperation.

[0020] At the same time, by controlling the time when the water inlet pipe valve is opened by the control component, the amount of water transported into the mixing drum can be gradually increased, while the amount of fertilizer in the mixing drum is fixed. Therefore, fertilizer liquid with different water ratios can be obtained, which can be suitable for different crops, different soil environments and different growth periods, and can further ensure the irrigation effect of the crops; when the water inlet pipe delivers water to the mixing drum, the irrigation water enters the mixing drum to flush the fertilizer on the bottom wall of the mixing drum, which is conducive to ensuring the mixing effect of fertilizer and water, and further ensures the subsequent irrigation effect of the crops.

[0021] Moreover, in the above-mentioned fertilizer liquid delivery mode, water no longer enters the water inlet pipe, so that water will not accumulate in the mixing barrel after the fertilizer liquid is extracted, thereby ensuring the fertilizer liquid ratio after the fertilizer and water are mixed next time, which is also beneficial to ensure the next watering effect on the crops.

[0024] Example 1: See also Figures 1 to 5 The present invention provides an integrated automatic fertilizer feeding device for water and fertilizer, primarily for automatically feeding fertilizer and ensuring effective irrigation of crops. The device comprises a housing 1, within which a mixing drum 4 is fixedly mounted. Fertilizer is placed in mixing drum 4, and when irrigation water enters mixing drum 4 and mixes with the fertilizer, a fertilizer liquid is obtained.

[0025] Furthermore, the housing 1 is internally provided with a piping assembly 2 for liquid transport. The piping assembly 2 comprises a main pipe 201 fixedly mounted on the housing 1, an inlet pipe 203 and a venturi tube 202 connected to the main pipe 201, and an outlet pipe 206 connected to the venturi tube 202. The inlet pipe 203 is also connected to the mixing drum 4 to ensure stable water supply to the mixing drum 4. The outlet pipe 206 is also connected to the mixing drum 4 to extract the fertilizer liquid from the mixing drum 4. The venturi tube 202 is a well-known existing technology and will not be described in detail here.

[0026] In the above structure, valves 204 are provided on the main pipe 201, the water inlet pipe 203 and the water outlet pipe 206, and the main pipe 201, the water inlet pipe 203 and the water outlet pipe 206 can be opened and closed accordingly through the valves 204; wherein, the pipeline assembly 2 also includes an adjusting gear 205 that rotates synchronously with the valve 204, and the number of the adjusting gears 205 is three and is fixedly connected to the three valves 204 in a one-to-one correspondence, and the interior of the shell 1 is provided with a control assembly 5 for driving the three adjusting gears 205 to rotate respectively, and the control assembly 5 includes a disc 502 and a collar 503, and the outer surface of the disc 502 and the inner wall of the collar 503 are respectively fixedly mounted with a first rack 505 and a second rack 506, and the number of the first rack 505 and the second rack 506 are both three, corresponding to the rotation adjustment of the three adjusting gears 205.

[0027] In the initial state, the valves 204 of the water inlet pipe 203 and the water outlet pipe 206 are closed, while the valve 204 of the main pipe 201 is open. At this time, the irrigation water can flow directly out through the main pipe 201, and the positions of the first rack 505 and the second rack 506 based on the disc 502 and the ring 503 are as shown. Figure 4 When the valve 204 of the main pipe 201 and the valve 204 of the outlet pipe 206 are closed and the valve 204 of the inlet pipe 203 is opened, the irrigation water delivered by the main pipe 201 will flow into the mixing drum 4 through the inlet pipe 203. During this process, the fertilizer in the material box 3 will be simultaneously delivered to the mixing drum 4 and form a fertilizer liquid in the mixing drum 4. Figure 4 The disc 502 and the collar 503 rotate counterclockwise, which in turn drives the regulating gear 205 corresponding to the valve 204 of the main pipe 201 to rotate and close the valve 204 of the main pipe 201. It also drives the regulating gear 205 corresponding to the valve 204 of the water inlet pipe 203 to rotate and open the valve 204 of the water inlet pipe 203. However, the regulating gear 205 corresponding to the valve 204 of the water outlet pipe 206 does not make contact. When the valve 204 of the main pipe 201 and the valve 204 of the water inlet pipe 203 are closed and the valve 204 of the water outlet pipe 206 is open, the venturi tube 202 draws the fertilizer liquid from the mixing drum 4 through the water outlet pipe 206 and discharges it along the main pipe 201. Figure 4 The middle disc 502 and the collar 503 continue to rotate counterclockwise, causing the corresponding regulating gear 205 of the valve 204 of the outlet pipe 206 to rotate, thereby opening the valve 204 of the outlet pipe 206. The regulating gear 205 of the corresponding valve 204 of the inlet pipe 203 rotates in the opposite direction, thereby closing the valve 204 of the inlet pipe 203. The valve 204 of the main pipe 201 remains closed. Based on the above, it can be seen that the three opening and closing modes of the valve 204 form three operating modes, corresponding to the irrigation water delivery mode, the fertilizer and water mixing mode, and the fertilizer liquid delivery mode.

[0028] The three switching modes of the valve 204 are realized by the control component 5, thereby completing the three working modes mentioned above. The control component 5 can also realize that the water inlet pipe 203 can deliver irrigation water of different proportions to the mixing drum 4, and then mix it with the fertilizer in the mixing drum 4 to obtain fertilizer liquid with different water ratios to meet the different needs of crops. Specifically, such as Figure 5 As shown, the left end of the venturi tube 202 is connected to the main pipe 201, while its right end is closed. In the first mode, irrigation water is transported from right to left through the main pipe 201. In the second mode, irrigation water flows from the right end of the main pipe 201 into the water inlet pipe 203, and then is transported from bottom to top through the water inlet pipe 203. In this mode, valve 204 of the main pipe 201 is closed, preventing irrigation water from right to left. In the third mode, fertilizer liquid is drawn into the venturi tube 202 through the outlet pipe 206 and then discharged through the left end of the main pipe 201. In this mode, valve 204 of the main pipe 201 is also closed, preventing irrigation water from right to left.

[0029] Reference Figures 2 to 4 In this embodiment, preferably, the control component 5 includes a motor (not shown in the figure) fixedly mounted on the main pipe 201, a round rod 501 is fixedly mounted on the output shaft of the motor, a disc 502 is fixedly mounted on the end of the round rod 501, a collar 503 is sleeved on the outer surface of the disc 502, and a cross bar 504 is fixedly mounted between the disc 502 and the collar 503. When the motor is started, the disc 502 and the collar 503 can rotate synchronously.

[0030] Further, such as Figure 4 As shown, the regulating gear 205 is subdivided into a first gear 2051 that rotates synchronously with the valve 204 of the main pipe 201, a second gear 2052 that rotates synchronously with the valve 204 of the water inlet pipe 203, and a third gear 2053 that rotates synchronously with the valve 204 of the water outlet pipe 206. The first gear 2051, the second gear 2052, and the third gear 2053 are all located between the disc 502 and the collar 503, and the first gear 2051, the second gear 2052, and the third gear 2053 are staggered front to back along the axial direction of the disc 502. In this embodiment, the second gear 2052 is located between the first gear 2051 and the third gear 2053, and the first gear 2051 is located at the front. The three first racks 505 and the three second racks 506 correspond to the first gear 2051, the second gear 2052, and the third gear 2053, respectively. That is, the first gear 2051, the second gear 2052, and the third gear 2053 each correspond to one first rack 505 and one second rack 506. Because the first gear 2051, the second gear 2052, and the third gear 2053 are arranged in a front-to-back staggered arrangement, the corresponding three first racks 505 and three second racks 506 are also arranged in a front-to-back staggered arrangement.

[0031] In the above structure, if Figure 4 As shown, in the initial state, the three first racks 505 and the three second racks 506 are Figure 4 , at which point valve 204 on main pipe 201 is open, while valves 204 on inlet pipe 203 and outlet pipe 206 are both closed, forming a delivery mode for irrigation water delivered by main pipe 201. When disc 502 drives the ring to rotate counterclockwise, disc 502 drives the three first racks 505 and the ring drives the three second racks 506 to rotate counterclockwise synchronously. The front first rack 505 contacts the first gear 2051 through the first gear 2051, driving valve 204 on main pipe 201 from an open state to a closed state. At this time, the front second rack 506 gradually moves away from the first gear 2051 from the lower left side of the first gear 2051. During this process, the middle first rack 505 contacts the second gear 2052 through the second gear 2052. The valve 204 on the water inlet pipe 203 is driven to change from a closed state to an open state. At this time, the middle second rack 506 gradually approaches the second gear 2052 from the upper left of the second gear 2052; and the rear first rack 505 and the rear second rack 506 gradually approach the third gear 2053. In this mode, the valve 204 of the main pipe 201 and the valve 204 of the outlet pipe 206 are closed, and the valve 204 of the water inlet pipe 203 is opened. The irrigation water flows from the main pipe 201 through the water inlet pipe 203 into the mixing drum 4 and is mixed with the fertilizer to form a fertilizer liquid, corresponding to the mixing mode of fertilizer and water.

[0032] Continuing the above process, the disc 502 drives the ring to continue to rotate counterclockwise. At this time, the first rack 505 and the second rack 506 on the front side gradually move away from the first gear 2051, so that the valve 204 on the main pipe 201 remains in the closed state, while the first rack 505 in the middle separates from the second gear 2052 and the second rack 506 in the middle contacts the second gear 2052, driving the second gear 2052 to rotate, so that the valve 204 on the water inlet pipe 203 returns from the open state to the closed state; then the second rack 506 in the rear moves away from the first gear 2051. A rack 505 can contact the third gear 2053 and drive the third gear 2053 to rotate, so that the valve 204 of the outlet pipe 206 is turned from a closed state to an open state through the third gear 2053, and the second rack 506 on the rear side also gradually approaches the third gear 2053. In this mode, the valve 204 of the main pipe 201 and the valve 204 of the water inlet pipe 203 are closed, and the valve 204 of the outlet pipe 206 is opened. The venturi tube 202 draws out the fertilizer liquid in the mixing drum 4 through the outlet pipe 206 and discharges it through the main pipe 201.

[0033] Through the above design, the valves 204 of the main pipe 201, the water inlet pipe 203 and the water outlet pipe 206 form three states and cycle back and forth between the three states. The first state is the initial state, in which the valve 204 of the main pipe 201 is open, while the valve 204 of the water inlet pipe 203 and the valve 204 of the water outlet pipe 206 are closed. The irrigation water is directly discharged through the main pipe 201, corresponding to the irrigation water delivery mode. The second state is the mixing state, in which the valve 204 of the water inlet pipe 203 is open, while the valve 204 of the main pipe 201 and the valve 204 of the water outlet pipe 206 are closed. The irrigation water enters the mixing drum 4 through the main pipe 201 and the water inlet pipe 203, and mixes with the fertilizer pre-placed in the mixing drum 4 to form a fertilizer liquid, corresponding to the fertilizer and water mixing mode. The third state is the fertilizer delivery state, in which the valve 204 of the water outlet pipe 206 is open, while the valve 204 of the main pipe 201 and the valve 204 of the water inlet pipe 203 are closed. The fertilizer liquid in the mixing drum 4 is automatically discharged through the outlet pipe 206, the venturi tube 202, and the main pipe 201, corresponding to the fertilizer liquid delivery mode.

[0034] It is understood that the fertilizer in the mixing drum 4 is pre-placed. When the disk 502 rotates to enter the fertilizer and water mixing mode, the water entering the mixing drum 4 automatically mixes with the fertilizer to form a fertilizer liquid. By adjusting the contact time between the second rack 506 and the second gear 2052, the time during which the second gear 2052 drives the valve 204 of the water inlet pipe 203 to be open can be extended, thereby increasing the amount of water entering the mixing drum 4 and producing fertilizer liquids with different water ratios. Alternatively, after the first rack 505 drives the second gear 2052 to rotate, opening the valve 204 of the water inlet pipe 203, the state of the disk 502 and the ring can be directly paused, similarly extending the time during which the second gear 2052 drives the valve 204 of the water inlet pipe 203 to be open, similarly producing fertilizer liquids with different water ratios.

[0035] Reference Figures 2 to 4 In this embodiment, preferably, a material box 3 connected to the mixing drum 4 is fixedly installed on the top of the housing 1. At this time, the fertilizer can be placed in the material box 3 in advance and intermittently transported to the mixing drum 4 by the material box 3. Specifically, Figure 2 As shown, a support rod 6 can be rotatably installed on the front side of the mixing drum 4, and a transmission connection is formed between the support rod 6 and the round rod 501 through a belt drive, and a feeding assembly 7 is commonly provided between the support rod 6 and the material box 3. In this embodiment, the feeding assembly 7 is a groove wheel intermittently rotating feeding mechanism, which and the belt drive are both existing mature technologies and will not be described in detail here.

[0036] The grooved wheels intermittently rotate the feeding mechanism, causing each rotation of the disc 502 and the ring to rotate one revolution. The belt drive on the round rod 501 also causes the support rod 6 to rotate one revolution, which in turn causes the feed box 3 to discharge once. During each rotation of the disc 502 and round rod 501, the pipeline assembly 2 sequentially completes the irrigation water delivery mode, the fertilizer and water mixing mode, and the fertilizer liquid delivery mode, before returning to the irrigation water delivery mode.

[0037] Reference Figure 6 and Figure 7 In this embodiment, preferably, a rotating assembly 8 is also rotatably mounted within the mixing drum 4. The rotating assembly 8, the round rod 501, and the support rod 6 are synchronously connected via a belt drive. When the round rod 501 drives the support rod 6 to rotate via the belt drive, the belt drive also synchronously drives the rotating assembly 8 to rotate. At this time, the rotating assembly 8 can continuously stir the irrigation water and fertilizer within the mixing drum 4, thereby ensuring a good mixing effect between the fertilizer and water, and further ensuring a good watering effect on the crops.

[0038] Specifically, the rotating assembly 8 includes a long rod 801 rotatably mounted on the mixing drum 4. The long rod 801, the round rod 501 and the support rod 6 are synchronously connected by a belt drive. A stirring blade 802 for stirring is fixedly mounted on the outer surface of the long rod 801. One end of the long rod 801 extends from the mixing drum 4 and is driven by the belt drive, and the other end is located in the mixing drum 4 for installing the stirring blade 802.

[0039] In summary, through the cooperation of the disc 502, the adjusting gear 205, the first rack 505 and the second rack 506 and other structures, the pipeline component 2 can automatically realize the cyclic switching between the irrigation water delivery mode, the fertilizer and water mixing mode and the fertilizer liquid delivery mode, thereby realizing the direct discharge of irrigation water, the automatic mixing of the fertilizer liquid, and the automatic fertilization of crops to ensure the irrigation effect of the crops; there is no need to repeatedly adjust the switching status of the main pipe 201 valve 204, the water inlet pipe 203 and the water outlet pipe 206 valve 204, which can not only meet the needs of efficient automation, but also effectively reduce the burden on workers and avoid the possibility of workers' misoperation.

[0040] At the same time, by controlling the time when the second gear 2052 drives the valve 204 of the water inlet pipe 203 to open, the amount of water transported into the mixing drum 4 can be gradually increased, while the amount of fertilizer in the mixing drum 4 is fixed. Therefore, fertilizer liquid with different water ratios can be obtained, which can be suitable for different crops, different soil environments and different growth periods, and can further ensure the irrigation effect of the crops; when the water inlet pipe 203 supplies water to the mixing drum 4, the irrigation water enters the mixing drum 4 and can flush the fertilizer on the bottom wall of the mixing drum 4, which is conducive to ensuring the mixing effect of fertilizer and water, and further ensures the subsequent irrigation effect of the crops.

[0041] Moreover, during the process of switching back and forth between the three modes, the water inlet pipe 203 no longer takes in water when the venturi tube 202 extracts the fertilizer liquid, so that water will not accumulate in the mixing barrel 4 after the fertilizer liquid is extracted, thereby ensuring the ratio of the fertilizer liquid after the fertilizer and water are mixed next time, which is also beneficial to ensuring the next irrigation effect on the crops.

[0042] And through the setting of the unloading component 7, after the pipeline component 2 completes one switch among the three modes, the material box 3 can transport a fixed amount of fertilizer into the mixing drum 4, so that the subsequent pipeline component 2 can directly switch to the next set of three modes, which can effectively improve the overall work efficiency and relatively ensure the fertilization efficiency.

[0043] Example 2: See also Figures 1 to 9 On the basis of the first embodiment, taking into account the continuity of automatic fertilization and the uncertainty of the required amount of fertilizer, the feeding assembly 7 is improved: the feeding assembly 7 now includes a circular plate 7003 fixedly mounted on the outside of the support rod 6 and a baffle 7001 slidably mounted in the material box 3. A connecting rod 7002 is mounted between the ends of the baffle 7001 and the circular plate 7003 for joint rotation. The baffle 7001 is inserted into the material box 3 to block the feeding of fertilizer, and it can slide horizontally based on the material box 3. Figure 9 As shown, the baffle 7001, the connecting rod 7002 and the circular plate 7003 form a crank-connecting rod 7002 mechanism, and when the circular plate 7003 rotates, the baffle 7001 can be driven to reciprocate horizontally through the connecting rod 7002.

[0044] Among them, such as Figure 8 and Figure 9 As shown, the inner wall of the material box 3 is fixed with a triangular block 301 that fits movably with the movable top surface of the baffle 7001. At this time, the rotation base point of the connecting rod 7002 and the circular plate 7003 is located directly below the circular plate 7003. Figure 8 When the baffle 7001 moves to the left, the blocking effect on the fertilizer can be maintained. At this time, the moving area of ​​the connecting rod 7002 based on the circular plate 7003 is located in the left half of the circular plate 7003; Figure 8 When the state moves to the right, the material box 3 can discharge the material into the mixing drum 4. At this time, the moving area of ​​the connecting rod 7002 based on the circular plate 7003 is located in the right half of the circular plate 7003.

[0045] Furthermore, when the baffle 7001 is based on Figure 8When the state moves to the right, the baffle 7001 separates from the triangular block 301, allowing the material box 3 to start unloading. At this time, the first rack 505 in the middle can be set to a state where it is not in contact with the second gear 2052, forming a process in which the material box 3 unloads material while the water inlet pipe 203 does not supply water to the mixing drum 4. In this state, the disc 502 and the circular plate 7003 can be paused for a corresponding period of time, allowing the material box 3 to deliver a sufficient amount of fertilizer to the mixing drum 4. Then, the first rack 505 in the middle can be contacted with the second gear 2052 to rotate, thereby causing the valve 204 of the water inlet pipe 203 to turn from a closed state to an open state. At this time, the mixing drum 4 can start to flow in water. With the valve 204 of the water inlet pipe 203 remaining in the open state and pausing for a corresponding period of time, a sufficient amount of irrigation water can be delivered to the mixing drum 4 again, thereby obtaining fertilizer liquids of different capacities at the same water ratio, allowing more crops to be irrigated at one time, further improving the fertilization efficiency.

[0046] Furthermore, when delivering a sufficient amount of fertilizer, the disk 502 need not be rotated multiple times; the entire fertilizing process can be achieved by rotating the disk 502 and the circular plate 7003 one rotation, thereby further improving fertilizing efficiency. Furthermore, since there is no need to rotate the disk 502 multiple times to sequentially deliver fertilizer and switch back and forth between the three modes, the overall continuity and automation of the fertilizing device are enhanced, resulting in better performance.
