Description

Technical Field

[0001] This invention relates to the field of intelligent agricultural power machinery technology, specifically to a quantitative fertilization device and fertilization method for agricultural planting. Background Technology

[0002] Chinese patent CN116076221B discloses an agricultural fertigation device that can quantitatively apply fertilizer. By setting up an auger blade to generate a downward rotational force and drive the dissolving ring to generate axial reciprocating swaying, at least two forces with different directions are formed in the tank, thereby improving the mixing effect of solid fertilizer components and water.

[0003] In agricultural planting, when fertilizing different types of crops, it is usually necessary to adjust the fertilizer concentration according to the crop characteristics and growth stage, rather than applying the same concentration of fertilizer uniformly. Furthermore, the ratio of nitrogen, phosphorus, and potassium in fertilizers varies significantly among different types of crops. Nitrogen, phosphorus, and potassium, as the three essential nutrients, are the most crucial and required nutrients for crop growth and development. Therefore, when using a quantitative fertilization device to fertilize different types of crops, it is necessary to adjust the nitrogen, phosphorus, and potassium ratio, fertilizer concentration in the water and fertilizer solution, and the amount of fertilizer applied based on the type of crop and the planting area. However, such devices cannot automatically control the weight of the input solid fertilizer; instead, the appropriate weight of solid fertilizer must be manually weighed and added to the device, and sufficient water must be added according to the fertilizer weight to ensure proper mixing. When using the same quantitative fertilization device for intercropping or adjacent planting of multiple crops, the water and fertilizer concentration needs to be readjusted for each type of crop. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a quantitative fertilization device and method for agricultural planting, which has the functions of automatically adjusting fertilizer concentration and rapid mixing, thus solving the problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] A quantitative fertilization device for agricultural planting includes a mixing tank, a storage tank, a quantitative conveying mechanism, a mixing mechanism, and an intelligent integrated machine. The mixing tank is equipped with an inlet and an outlet. The storage tank is used to store three types of solid fertilizers: nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer. The mixing mechanism is installed on the mixing tank and is used to stir and mix the solid fertilizers and water. The intelligent integrated machine is used to control the conveying and mixing of materials in the quantitative fertilization device and to transport the mixed fertilizer and water to the plot where the crop is located through the irrigation pipe of the corresponding crop.

[0009] The quantitative conveying mechanism includes a weighing platform and a conveying assembly. The storage tank is installed on the weighing platform, and an electromagnetic valve is provided at the discharge end of the storage tank. The conveying assembly is installed on one side of the weighing platform and is used to convey the solid fertilizer output from the storage tank to the mixing tank. When the electromagnetic valve is opened, the solid fertilizer flows from the storage tank into the interior of the conveying assembly. The weight of the storage tank is detected in real time by the weighing platform. When the weighing platform detects that the weight drop of the storage tank reaches the preset quantitative value, the intelligent integrated machine controls the electromagnetic valve to close and prevent the storage tank from continuing to discharge.

[0010] The mixing mechanism includes a mixing shaft, a dispersing shaft, and a stirring shaft, all of which are rotatably installed inside the mixing tank, and the mixing shaft rotates synchronously with the stirring shaft. When the mixing shaft rotates forward, it can drive the dispersing shaft to rotate, and the dispersing shaft can drive the conveying component to convey solid fertilizer. At the same time, the dispersing shaft can also disperse the solid fertilizer that enters the mixing tank. When the mixing shaft rotates in reverse, the dispersing shaft stops rotating.

[0011] Preferably, the mixing mechanism includes a dispersing component, which includes an inner sleeve, an outer sleeve, a connecting pipe, a drive gear, and a driven gear. The inner sleeve is fixedly mounted on the mixing shaft, and the outer sleeve is rotatably mounted inside the mixing drum. A radial groove is formed on the outer side wall of the inner sleeve, and a one-way locking block is slidably mounted in the radial groove. A support spring is fixedly mounted between the one-way locking block and the radial groove. A one-way slot is formed on the inner side wall of the outer sleeve, and the one-way slot is adapted to engage with the one-way locking block. The connecting pipe is fixedly mounted on the lower end of the outer sleeve, the drive gear is fixedly mounted on the connecting pipe, and the driven gear is fixedly mounted on the dispersing shaft, and the driven gear is meshed with the drive gear.

[0012] Preferably, the mixing mechanism further includes a mixing motor, the drive end of which is fixedly connected to the mixing shaft, a support pipe is fixedly installed at the upper end of the mixing tank, the mixing motor is fixedly installed on the support pipe, and the outer sleeve is rotatably connected to the inner wall of the support pipe.

[0013] Preferably, the mixing mechanism further includes an anti-reverse component, which includes a retraction groove, a one-way limiting block, and a one-way limiting groove. The retraction groove is disposed on the side wall of the support tube, and the opening end of the retraction groove faces the inside of the support tube. The one-way limiting block is slidably installed inside the retraction groove, and a limiting spring is fixedly installed between the one-way limiting block and the retraction groove. The one-way limiting groove is opened on the outer side wall of the outer tube, and the one-way limiting groove is adapted to and engaged with the one-way limiting block. The end faces of the one-way limiting groove and the one-way locking groove are both set as inclined surfaces, and the inclination directions of the one-way limiting groove and the one-way locking groove are opposite. A pull rod is fixedly installed on the one-way limiting block, and the pull rod is slidably connected to the support tube.

[0014] Preferably, the upper end of the stirring shaft is provided with an axial groove, the lower end of the mixing shaft is fixedly installed with a lifting slider, the lifting slider is slidably installed inside the axial groove, the side of the stirring shaft is provided with an inclined annular groove, and a stop block is fixedly installed on the inner side wall of the connecting pipe. The stop block is slidably connected with the inclined annular groove, and the stop block can drive the stirring shaft to move up and down along the trajectory of the inclined annular groove.

[0015] Preferably, the conveying assembly includes a vertical conveying pipe, a feeding pipe, a discharging pipe, a vertical auger shaft, and a transmission pulley. The vertical conveying pipe is fixedly installed on one side of the weighing platform. The feeding pipe and the discharging pipe are respectively fixedly installed at both ends of the vertical conveying pipe. The feeding pipe is correspondingly arranged with the discharge end of the storage tank. The vertical auger shaft is rotatably installed inside the vertical conveying pipe, and the vertical auger shaft is connected to the dispersing shaft through a transmission pulley. The output end of the discharging pipe extends into the interior of the mixing tank.

[0016] Preferably, a push rod is slidably inserted into the top of the feeding pipe, and a push plate is slidably arranged inside the feeding pipe. The push plate and the push rod are fixedly connected. A return spring is fixedly installed between the end of the push rod and the top of the feeding pipe. A feed hopper is installed on the side of the top of the feeding pipe.

[0017] Preferably, the lower end of the storage tank is provided with a discharge port, which is inserted into the inner side of the feed hopper. The solenoid valve is provided on the discharge port. The upper end of the storage tank is provided with a feeding hopper, which is threaded with a screw cap. A transparent observation window is provided on the side of the storage tank.

[0018] Preferably, a water pump and a drainage pump are installed on one side of the intelligent all-in-one machine. The pumping end of the water pump is connected to an external water source, and the delivery end of the water pump is connected to the water inlet. The pumping end of the drainage pump is connected to the drain outlet, and the delivery end of the drainage pump is connected to all the branch irrigation pipes. Each branch irrigation pipe is equipped with an electrically controlled valve. The electrically controlled valve, the solenoid valve, the water pump, and the drainage pump are all electrically connected to the intelligent all-in-one machine.

[0019] This invention also discloses a fertilization method for agricultural planting, the specific steps of which are as follows:

[0020] The intelligent integrated machine controls the external water source to inject an appropriate amount of water into the mixing tank through the water inlet on the mixing tank. Then, the intelligent integrated machine controls the opening of the solenoid valve at the discharge end of the storage tank. After the solenoid valve is opened, the corresponding type of solid fertilizer flows from the storage tank into the conveying component of the quantitative conveying mechanism. At the same time, during the process of solid fertilizer flowing out, the weighing platform detects the weight of the storage tank in real time. When the weighing platform detects that the weight drop of the storage tank reaches the value of solid fertilizer added preset by the intelligent integrated machine, the intelligent integrated machine immediately controls the solenoid valve to close, preventing the storage tank from continuing to discharge, thus completing the quantitative output of solid fertilizer.

[0021] As the electromagnetic valve opens, allowing solid fertilizer to be output from the storage tank, the intelligent integrated machine synchronously controls the start of the mixing mechanism, causing the mixing shaft of the mixing mechanism to start rotating forward. When the mixing shaft rotates forward, it drives the dispersing shaft to rotate. The rotating dispersing shaft drives the conveying component to operate, conveying a fixed amount of solid fertilizer in the conveying component to the mixing tank. On the other hand, the dispersing shaft can also disperse the solid fertilizer that enters the mixing tank.

[0022] After the solenoid valve is closed, the intelligent integrated machine controls the mixing shaft to reverse. At this time, the dispersing shaft stops rotating, and the stirring shaft rotates independently to continue stirring and mixing until the stirring is completed and the mixing mechanism stops mixing.

[0023] Subsequently, the intelligent integrated machine controls the mixing of water and fertilizer, which is then discharged through the drain on the mixing tank. The discharged water and fertilizer are then guided to the irrigation pipes of the corresponding crops, and finally transported to the plots where the crops are located through the irrigation pipes, completing the fertilization operation for the crops.

[0024] (III) Beneficial Effects

[0025] Compared with the prior art, the present invention provides a quantitative fertilization device and fertilization method for agricultural planting, which has the following beneficial effects:

[0026] 1. This quantitative fertilization device, through the installation of storage tanks, a weighing platform, electromagnetic valves, and an intelligent integrated machine, achieves precise quantitative control of three types of solid fertilizers: nitrogen, phosphorus, and potassium. Three storage tanks store different types of solid fertilizers respectively, and the weighing platform monitors the weight changes in the tanks in real time. When the weight drop in a tank reaches a preset quantitative value, the intelligent integrated machine automatically controls the electromagnetic valve to close, completing the quantitative fertilizer output without manual weighing. This not only adapts to the differentiated nitrogen, phosphorus, and potassium ratio requirements of different crops but also allows for flexible adjustment of the fertilizer application rate based on the planting area, effectively avoiding human error and improving fertilization accuracy.

[0027] 2. This quantitative fertilizer application device, by setting up a mixing shaft, a dispersing shaft, a stirring shaft, and a dispersing component, when the mixing shaft rotates forward, the one-way locking block of the inner sleeve engages with the one-way locking groove of the outer sleeve under the action of the supporting spring, driving the drive gear on the outer sleeve and the connecting pipe to rotate, thereby driving the driven gear and the dispersing shaft to rotate. When the dispersing shaft rotates, it can not only drive the vertical auger shaft to operate, stably transporting the solid fertilizer to the mixing tank, but also stir and disperse the solid fertilizer entering the mixing tank, preventing the fertilizer from clumping.

[0028] 3. This quantitative fertilization device, by setting a retraction groove, a one-way limiting block, and a one-way limiting groove, prevents the outer tube from rotating in the opposite direction by engaging with the one-way limiting groove of the outer tube under the action of the limiting spring. This avoids the dispersion shaft from being accidentally started when the mixing shaft reverses, ensuring the orderly switching between conveying and dispersing actions. At the same time, by setting an axial sliding groove, a lifting slider, an inclined ring groove, and a stop, when the outer tube cannot rotate synchronously with the mixing shaft, the mixing shaft will swing up and down when it rotates, thereby increasing the mixing range and ensuring that the solid fertilizer and water are quickly and evenly mixed.

[0041] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Example 1

[0043] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 10 This invention provides a quantitative fertilization device for agricultural planting, including a mixing tank 1, a storage tank 2, a quantitative conveying mechanism 3, a mixing mechanism 4, and an intelligent integrated machine 5. The mixing tank 1 is provided with a water inlet 11 and a drain outlet 12. The storage tank 2 is used to store three types of solid fertilizers: nitrogen fertilizer, phosphorus fertilizer, and potassium fertilizer. The mixing mechanism 4 is installed on the mixing tank 1 and is used to stir and mix the solid fertilizers and water. The intelligent integrated machine 5 is used to control the conveying and mixing of materials in the quantitative fertilization device and to transport the mixed water and fertilizer to the plot where the crop is located through the irrigation pipe of the corresponding crop.

[0044] The quantitative conveying mechanism 3 includes a weighing platform 31 and a conveying component 32. The storage tank 2 is installed on the weighing platform 31. The discharge end of the storage tank 2 is equipped with an electromagnetic valve 21. The conveying component 32 is installed on one side of the weighing platform 31 and is used to convey the solid fertilizer output from the storage tank 2 to the mixing tank 1. When the electromagnetic valve 21 is opened, the solid fertilizer flows from the storage tank 2 into the interior of the conveying component 32. The weight of the storage tank 2 is detected in real time by the weighing platform 31. When the weighing platform 31 detects that the weight drop of the storage tank 2 reaches the preset quantitative value, the intelligent integrated machine 5 controls the electromagnetic valve 21 to close and prevent the storage tank 2 from continuing to discharge.

[0045] The mixing mechanism 4 includes a mixing shaft 41, a dispersing shaft 42, and a stirring shaft 43. The mixing shaft 41, dispersing shaft 42, and stirring shaft 43 are all rotatably installed inside the mixing tank 1, and the mixing shaft 41 and the stirring shaft 43 rotate synchronously. When the mixing shaft 41 rotates forward, it can drive the dispersing shaft 42 to rotate. The dispersing shaft 42 can drive the conveying component 32 to convey solid fertilizer. At the same time, the dispersing shaft 42 can also disperse the solid fertilizer that enters the mixing tank 1. When the mixing shaft 41 rotates in reverse, the dispersing shaft 42 stops rotating.

[0046] As can be seen from the above, this quantitative fertilization device, through the setting of storage tank 2, weighing platform 31, electromagnetic valve 21, and intelligent integrated machine 5, realizes the functions of quantitative delivery of solid fertilizer, solid-liquid mixing, and directional delivery of water and fertilizer. Among them, the three storage tanks 2 can store nitrogen, phosphorus, and potassium as three core solid fertilizers to meet the nutrient ratio requirements of different crops. At the same time, the quantitative delivery mechanism 3 relies on the weighing platform 31 to detect the weight change of the storage tank 2 in real time, and combined with the intelligent integrated machine 5 to control the opening and closing of the electromagnetic valve 21, thereby controlling the output of solid fertilizer. The mixing mechanism 4, through the coordinated action of mixing shaft 41, dispersing shaft 42, and stirring shaft 43, simultaneously realizes fertilizer dispersion during the fertilizer delivery stage and focuses on solid-liquid mixing during the mixing stage to ensure uniform water and fertilizer mixing. The weighing platform 31 in this application consists of a horizontal platform and a weighing structure installed on the platform, fixing the storage tank 2 on the weighing structure, and monitoring the weighing results in real time through the intelligent integrated machine 5.

[0047] When using this device, the intelligent integrated machine 5 controls an external water source to inject an appropriate amount of water into the mixing tank 1 through the water inlet 11 on the mixing tank 1. Then, the intelligent integrated machine 5 controls the opening of the solenoid valve 21 at the discharge end of the storage tank 2. After the solenoid valve 21 is opened, the corresponding type of solid fertilizer flows from the storage tank 2 into the conveying component 32 of the quantitative conveying mechanism 3. At the same time, during the process of solid fertilizer flowing out, the weighing platform 31 detects the weight of the storage tank 2 in real time. When the weighing platform 31 detects that the weight drop of the storage tank 2 reaches the value of solid fertilizer added preset by the intelligent integrated machine 5, the intelligent integrated machine 5 immediately controls the solenoid valve 21 to close, preventing the storage tank 2 from continuing to discharge, thus completing the quantitative output of solid fertilizer. During the process of the solenoid valve 21 opening and allowing solid fertilizer to be output from the storage tank 2, the intelligent integrated machine 5 synchronously controls the mixing mechanism 4. The mixing mechanism 4 is started, causing the mixing shaft 41 of the mixing mechanism 4 to start rotating forward. When the mixing shaft 41 rotates forward, it drives the dispersing shaft 42 to rotate. The rotating dispersing shaft 42 drives the conveying component 32 to operate, conveying a certain amount of solid fertilizer in the conveying component 32 to the mixing tank 1. On the other hand, the dispersing shaft 42 can also disperse the solid fertilizer that enters the mixing tank 1. After the solenoid valve 21 is closed, the intelligent integrated machine 5 controls the mixing shaft 41 to reverse. At this time, the dispersing shaft 42 stops rotating, and the stirring shaft 43 rotates independently to continue stirring and mixing until the stirring is completed. Then the mixing mechanism 4 stops mixing. Subsequently, the intelligent integrated machine 5 controls the mixed water and fertilizer to be discharged through the drain outlet 12 on the mixing tank 1, and guides the discharged water and fertilizer to the irrigation pipe of the corresponding crop. Finally, the water and fertilizer are transported to the plot where the crop is located through the irrigation pipe to complete the fertilization operation of the crop.

[0048] Example 2

[0049] like Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, the difference between this embodiment and the above embodiment is that the mixing mechanism 4 includes a dispersing component 44, which includes an inner sleeve 441, an outer sleeve 442, a connecting pipe 447, a driving gear 448, and a driven gear 449. The inner sleeve 441 is fixedly installed on the mixing shaft 41, and the outer sleeve 442 is rotatably installed inside the mixing barrel 1. A radial groove 443 is provided on the outer side wall of the inner sleeve 441, and a one-way locking block 444 is slidably installed in the radial groove 443. A support spring 445 is fixedly installed between the one-way locking block 444 and the radial groove 443. A one-way slot 446 is provided on the inner side wall of the outer sleeve 442, and the one-way slot 446 is adapted to engage with the one-way locking block 444. The connecting pipe 447 is fixedly installed at the lower end of the outer sleeve 442, the driving gear 448 is fixedly installed on the connecting pipe 447, and the driven gear 449 is fixedly installed on the dispersing shaft 42, and the driven gear 449 is meshed with the driving gear 448.

[0050] As can be seen from the above, when the mixing shaft 41 rotates forward, the one-way locking block 444, under the action of the support spring 445, is locked into the one-way locking groove 446 of the outer sleeve 442. At this time, the outer sleeve 442 and the inner sleeve 441 rotate synchronously, thereby driving the connecting pipe 447 and the drive gear 448 to rotate. The drive gear 448 then drives the dispersing shaft 42 to rotate through the meshing driven gear 449. When the mixing shaft 41 rotates in reverse, the one-way locking block 444 is compressed by the reaction force of the inclined surface of the one-way locking groove 446, and disengages from the one-way locking groove 446. The inner sleeve 441 rotates freely, and the outer sleeve 442 and the dispersing shaft 42 stop rotating, thereby realizing the one-way power transmission of the dispersing shaft 42.

[0051] The mixing mechanism 4 also includes a mixing motor 45, the drive end of which is fixedly connected to the mixing shaft 41. A support tube 13 is fixedly installed on the upper end of the mixing tank 1. The mixing motor 45 is fixedly installed on the support tube 13. The outer sleeve 442 is rotatably connected to the inner wall of the support tube 13.

[0052] As can be seen from the above, the hybrid motor 45 is used to drive the hybrid shaft 41 to achieve forward and reverse rotation as needed. The support tube 13 not only provides a fixed installation position for the hybrid motor 45, but also provides rotational support for the outer tube 442, ensuring that the outer tube 442 rotates stably under the drive of the hybrid shaft 41.

[0053] Example 3

[0054] like Figure 5 , Figure 7 , Figure 8 and Figure 9As shown, the difference between this embodiment and the above embodiment is that the mixing mechanism 4 further includes an anti-reverse component 46. The anti-reverse component 46 includes a retraction groove 461, a one-way limiting block 462, and a one-way limiting groove 464. The retraction groove 461 is disposed on the side wall of the support tube 13, and the opening end of the retraction groove 461 faces the inside of the support tube 13. The one-way limiting block 462 is slidably installed inside the retraction groove 461, and the one-way limiting block 462 and the retraction groove 464 are connected. A limit spring 463 is fixedly installed between the two tubes. A one-way limit groove 464 is opened on the outer wall of the outer tube 442 and is adapted to and engaged with the one-way limit block 462. The end faces of the one-way limit groove 464 and the one-way slot 446 are both set as inclined surfaces, and the inclination directions of the one-way limit groove 464 and the one-way slot 446 are opposite. A pull rod 465 is fixedly installed on the one-way limit block 462 and is slidably connected to the support tube 13.

[0055] As can be seen from the above, when the mixing shaft 41 rotates forward, driving the outer sleeve 442 to rotate, the one-way limiting block 462 is squeezed by the inclined surface of the one-way limiting groove 464, compressing the limiting spring 463 and retracting into the retraction groove 461, which does not affect the forward rotation of the outer sleeve 442. When the outer sleeve 442 has a tendency to reverse due to the rotation of the inner sleeve 441, the one-way limiting block 462 is stuck into the one-way limiting groove 464 under the action of the limiting spring 463, preventing the outer sleeve 442 from reversing, thus avoiding the reverse rotation of the dispersing shaft 42, which could cause the conveying component 32 to malfunction or the fertilizer conveying to become disordered. The setting of the pull rod 465 facilitates manual operation. The one-way limiting block 462 can be disengaged from the one-way limiting groove 464 by pulling the pull rod 465, which is convenient for equipment maintenance or adjustment under special working conditions.

[0056] An axial groove 431 is provided at the upper end of the stirring shaft 43, and a lifting slider 411 is fixedly installed at the lower end of the mixing shaft 41. The lifting slider 411 is slidably installed inside the axial groove 431. An inclined annular groove 432 is provided on the side of the stirring shaft 43. A stop block 433 is fixedly installed on the inner wall of the connecting pipe 447. The stop block 433 is slidably connected to the inclined annular groove 432, and the stop block 433 can drive the stirring shaft 43 to move up and down along the trajectory of the inclined annular groove 432.

[0057] As can be seen from the above, by setting the axial sliding groove 431 and the lifting slider 411, the stirring shaft 43 can rotate synchronously with the mixing shaft 41 and slide up and down relative to the mixing shaft 41. When the outer sleeve 442 cannot rotate synchronously with the inner sleeve 441, the connecting pipe 447 rotates relative to the stirring shaft 43, so that the stop block 433 slides in the inclined annular groove 432, thereby allowing the stirring shaft 43 to move up and down while rotating.

[0058] Example 4

[0059] like Figure 2 , Figure 3 and Figure 4As shown, the difference between this embodiment and the above embodiments is that the conveying assembly 32 includes a vertical conveying pipe 321, a feeding pipe 322, a discharging pipe 323, a vertical auger shaft 324, and a transmission pulley 325. The vertical conveying pipe 321 is fixedly installed on one side of the weighing platform 31. The feeding pipe 322 and the discharging pipe 323 are respectively fixedly installed at both ends of the vertical conveying pipe 321. The feeding pipe 322 is correspondingly arranged with the discharge end of the storage tank 2. The vertical auger shaft 324 is rotatably installed inside the vertical conveying pipe 321, and the vertical auger shaft 324 is connected to the dispersing shaft 42 through the transmission pulley 325. The output end of the discharging pipe 323 extends into the interior of the mixing tank 1.

[0060] As can be seen from the above, the feeding pipe 322 receives the fertilizer output from the storage tank 2. The vertical auger shaft 324 rotates under the power transmitted by the dispersing shaft 42 through the transmission pulley 325, which conveys the fertilizer in the feeding pipe 322 upward to the discharge pipe 323, and then the discharge pipe 323 accurately feeds it into the mixing tank 1, so as to avoid the fertilizer from scattering during the conveying process and ensure that the quantitative fertilizer completely enters the mixing process.

[0061] A push rod 326 is slidably inserted into the top of the feeding pipe 322, and a push plate 327 is slidably arranged inside the feeding pipe 322. The push plate 327 and the push rod 326 are fixedly connected. A return spring 328 is fixedly installed between the end of the push rod 326 and the top of the feeding pipe 322. A feed hopper 329 is installed on the side of the top of the feeding pipe 322.

[0062] As can be seen from the above, when fertilizer accumulates in the feeding pipe 322, the push rod 326 drives the push plate 327 to move downward, pushing the accumulated fertilizer towards the vertical conveying pipe 321. At the same time, after the push rod 326 is released, the reset spring 328 drives the push plate 327 and the push rod 326 to reset, waiting for the next use. By setting the feeding hopper 329, it is convenient to receive the fertilizer output from the outlet 22 of the storage tank 2, and avoid fertilizer leakage.

[0063] The lower end of the storage tank 2 is provided with a discharge port 22, which is inserted into the inner side of the feed hopper 329. The solenoid valve 21 is provided on the discharge port 22. The upper end of the storage tank 2 is provided with a feeding hopper 23, and a screw cap 24 is threaded on the feeding hopper 23. The side of the storage tank 2 is provided with a transparent observation window 25.

[0064] As can be seen from the above, the storage tank 2 is connected to the feed hopper 329 through the outlet 22 to ensure that the fertilizer can flow accurately into the conveying component 32 and reduce leakage. Since the solenoid valve 21 is set at the outlet 22, the fertilizer output can be precisely controlled. By setting the feed hopper 23 and the screw cap 24, it is convenient to add fertilizer to the storage tank 2. At the same time, the screw cap 24 can prevent the fertilizer from getting damp or contaminated. By setting the transparent observation window 25, it is convenient for the operator to intuitively see the remaining amount of fertilizer in the storage tank 2.

[0065] A water pump 51 and a drain pump 52 are installed on one side of the intelligent all-in-one machine 5. The water pump 51 is connected to an external water source and the water delivery end is connected to the water inlet 11. The water pump 52 is connected to the drain outlet 12 and the water delivery end is connected to all the branch irrigation pipes. Each branch irrigation pipe is equipped with an electrically controlled valve. The electrically controlled valve, the solenoid valve 21, the water pump 51, and the drain pump 52 are all electrically connected to the intelligent all-in-one machine 5.

[0066] As can be seen from the above, the water pump 51 is used to provide water to the mixing tank 1. The intelligent integrated machine 5 controls the start and stop and working time of the water pump 51 to precisely control the amount of water injected into the mixing tank 1, thereby adjusting the water and fertilizer concentration. The drain pump 52 is responsible for drawing the mixed water and fertilizer from the mixing tank 1 and transporting it to the irrigation pipe. By setting an electrically controlled valve on the branch irrigation pipe, the on / off of the corresponding irrigation pipe can be controlled according to the fertilization needs, so as to realize the targeted fertilization of different concentrations and amounts of water and fertilizer for different plots or different crops.

[0067] Example 5

[0068] Please see Figure 1 - Figure 10 The present invention also discloses a fertilization method for agricultural planting, the specific steps of which are as follows:

[0069] The intelligent integrated machine 5 controls the external water source to inject an appropriate amount of water into the mixing tank 1 through the water inlet 11 on the mixing tank 1. Then, the intelligent integrated machine 5 controls the electromagnetic valve 21 at the discharge end of the storage tank 2 to open. After the electromagnetic valve 21 is opened, the corresponding type of solid fertilizer flows from the storage tank 2 into the conveying component 32 of the quantitative conveying mechanism 3. At the same time, during the process of solid fertilizer flowing out, the weighing platform 31 detects the weight of the storage tank 2 in real time. When the weighing platform 31 detects that the weight drop of the storage tank 2 reaches the value of solid fertilizer added preset by the intelligent integrated machine 5, the intelligent integrated machine 5 immediately controls the electromagnetic valve 21 to close, preventing the storage tank 2 from continuing to discharge, and completing the quantitative output of solid fertilizer.

[0070] During the process of opening the electromagnetic valve 21 to output solid fertilizer from the storage tank 2, the intelligent integrated machine 5 synchronously controls the mixing mechanism 4 to start, causing the mixing shaft 41 of the mixing mechanism 4 to start rotating forward. When the mixing shaft 41 rotates forward, it drives the dispersing shaft 42 to rotate. The rotating dispersing shaft 42 drives the conveying component 32 to operate, conveying a certain amount of solid fertilizer in the conveying component 32 to the mixing tank 1. On the other hand, the dispersing shaft 42 can also disperse the solid fertilizer that enters the mixing tank 1.

[0071] After the solenoid valve 21 is closed, the intelligent all-in-one machine 5 controls the mixing shaft 41 to reverse. At this time, the dispersing shaft 42 stops rotating, and the stirring shaft 43 rotates independently to continue stirring and mixing until the stirring is completed and the mixing mechanism 4 stops mixing.

[0072] Subsequently, the intelligent all-in-one machine 5 controls the mixing of water and fertilizer, which is then discharged through the drain outlet 12 on the mixing tank 1. The discharged water and fertilizer are then guided to the irrigation pipes of the corresponding crops, and finally transported to the plots where the crops are located through the irrigation pipes, thus completing the fertilization operation for the crops.

[0073] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

10. A fertilization method for agricultural planting, using a quantitative fertilization device for agricultural planting as described in any one of claims 1-9, characterized in that, The specific steps are as follows: The intelligent integrated machine controls the external water source to inject an appropriate amount of water into the mixing tank through the water inlet on the mixing tank. Then, the intelligent integrated machine controls the opening of the solenoid valve at the discharge end of the storage tank. After the solenoid valve is opened, the corresponding type of solid fertilizer flows from the storage tank into the conveying component of the quantitative conveying mechanism. At the same time, during the process of solid fertilizer flowing out, the weighing platform detects the weight of the storage tank in real time. When the weighing platform detects that the weight drop of the storage tank reaches the value of solid fertilizer added preset by the intelligent integrated machine, the intelligent integrated machine immediately controls the solenoid valve to close, preventing the storage tank from continuing to discharge, thus completing the quantitative output of solid fertilizer. As the electromagnetic valve opens, allowing solid fertilizer to be output from the storage tank, the intelligent integrated machine synchronously controls the start of the mixing mechanism, causing the mixing shaft of the mixing mechanism to start rotating forward.
