Description

Technical Field

[0001] This invention relates to the field of fertilization and pesticide application technology, and specifically to an automated fertilization and pesticide application device for agricultural planting. Background Technology

[0002] In agricultural planting, especially in the large-scale production of cash crops such as sugarcane, the precise and efficient application of fertilizers and pesticides is a key link in ensuring crop yield and quality. Traditional fertilization and pesticide application operations usually involve manually or mechanically mixing fertilizer or pesticide concentrates with a large amount of water in a large container to achieve the target concentration before applying them through sprinkler or drip irrigation systems.

[0003] For scenarios requiring simultaneous application of fertilizers and pesticides, or for comparative experiments of multiple agents on the same plot, traditional devices often only allow for single, large-scale pre-mixing. This method is not only time-consuming and labor-intensive, but also inconvenient due to waste caused by excessive mixing and the need for remixing when the mixing is insufficient. It cannot achieve flexible operation of mixing on demand. Even if the fertilizer solution is mixed evenly inside the tank, it may separate into layers due to prolonged storage. Therefore, we propose an automated fertilizer and pesticide application device for agricultural planting. Summary of the Invention

[0004] The purpose of this invention is to provide an automated fertilization and pesticide application device for agricultural planting, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automated agricultural planting fertilization and pesticide application device, comprising:

[0014] Preferably, the second pump assembly includes a second pump body and a second pumping pipe. The second pump body is fixed to the top of the tank. One end of the second pumping pipe is connected to the inlet of the second pump body. The other end of the second pumping pipe passes through a partition plate to communicate with the fertilizer liquid chamber inside the tank. One end of the return pipe extends to the inside of the fertilizer liquid chamber.

[0015] Preferably, the height of the lower opening of the return pipe is higher than the height of the lower opening of the second suction pipe, and the lower end of the return pipe is detachably connected to a spray head for dispersing the liquid.

[0030] 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.

[0031] Please see Figures 1-6This invention provides a technical solution: an automated agricultural planting fertilization and pesticide application device, comprising:

[0032] Tank 1, with a static mixer 2 on the front surface of tank 1;

[0033] The liquid pipe 8 is connected to one side wall of the static mixer 2, and one end of the liquid pipe 8 is connected to a first pump assembly that communicates with the inside of the tank 1.

[0034] Fertilizer liquid pipe 7 facilitates the flow of fertilizer liquid into the static mixer 2 through fertilizer liquid pipe 7;

[0035] The water inlet pipe 3 and the fertilizer solution pipe 7 are respectively connected to the inlet on the static mixer 2 to facilitate the flow of water to reduce the concentration of fertilizer or pesticide solution. A flow meter and an electromagnetic control valve are installed on the water inlet pipe 3 along its axial direction to adjust the water flowing into the static mixer 2.

[0036] A three-way valve 5 is installed at one end of the fertilizer solution pipe 7, and the lower end of the three-way valve 5 has a return pipe 6 that communicates with the inside of the tank 1. A second pumping assembly 4 for drawing fertilizer solution from the inside of the tank 1 is installed at one end of the three-way valve 5.

[0037] By setting a return pipe 6 at the lower end of the three-way valve 5 to connect with the inside of the tank 1, and cooperating with the second pump liquid assembly 4 to circulate and return the fertilizer liquid inside the tank 1, the high-concentration fertilizer liquid can form a forced convection circulation in the fertilizer liquid chamber, effectively preventing the sedimentation of water-soluble fertilizer particles and concentration stratification, thereby improving the uniformity of mixing of high-concentration fertilizer liquid after long-term storage, ensuring that the concentration of fertilizer liquid extracted each time is consistent, and thus ensuring the uniformity and accuracy of fertilization in the field.

[0038] A partition plate 11 is fixed to the inside of the tank 1 to divide the space inside the tank 1 to form a fertilizer chamber and a medicine chamber.

[0039] When applying fertilizer and pesticide simultaneously, the fertilizer and pesticide solutions do not need to be pre-mixed and prepared on a large scale in tank 1. Instead, they are transported to the static mixer 2 via their respective independent supply paths for immediate mixing and output. This method completely changes the traditional "premix-storage-application" operation mode, and is especially suitable for field efficacy comparison tests that require frequent switching between different pesticide solutions and the same fertilizer solution. It eliminates the need for repeated cleaning of mixing containers, significantly improving operational efficiency and test accuracy. Furthermore, it allows for the simultaneous storage and separate supply of fertilizer and pesticide solutions with a single set of equipment, reducing equipment footprint, lowering manufacturing costs, and facilitating field mobility and deployment.

[0040] Preferably, the first pump assembly includes a first suction pipe 91, a first pump body 92, a first flow meter 93, and a first solenoid valve 94. The first pump body 92 is fixed to the upper surface of the tank 1, the first suction pipe 91 is connected to the inlet of the first pump body 92, one end of the first suction pipe 91 is connected to the medicine chamber inside the tank 1, and the first flow meter 93 and the first solenoid valve 94 are arranged sequentially along the axial direction of the medicine pipe 8.

[0041] It can acquire the instantaneous flow rate data of the liquid medicine in real time, and combine it with the first solenoid valve 94 to realize the automatic adjustment and on / off control of the flow rate, so as to ensure that the liquid medicine, fertilizer solution and water solution are accurately mixed in a preset ratio and improve the accuracy of medicine preparation.

[0042] Preferably, one side wall of the tank body 1 has a first inlet 10 for adding medicine to the inside of the medicine chamber;

[0043] Operators can directly replenish the original drug solution into the drug solution chamber.

[0044] Preferably, the second pump assembly 4 includes a second pump body 41 and a second pump pipe 42. The second pump body 41 is fixed to the top of the tank 1. One end of the second pump pipe 42 is connected to the inlet of the second pump body 41, and the other end of the second pump pipe 42 passes through the partition plate 11 to communicate with the fertilizer chamber inside the tank 1. One end of the return pipe 6 extends to the inside of the fertilizer chamber.

[0045] After the second pump body 41 draws fertilizer solution from the fertilizer solution chamber through the second extraction pipe 42, it switches to the return pipe 6 through the three-way valve 5 and returns the fertilizer solution to the inside of the fertilizer solution chamber, so that the fertilizer solution forms a circulation loop between the tank body 1 and the external pipeline, which effectively solves the problem of water and fertilizer stratification and particle sedimentation caused by the static setting of high-concentration fertilizer solution, or introduces the fertilizer solution into the static mixer 2 through the three-way valve 5.

[0046] Preferably, the height of the lower opening of the return pipe 6 is higher than the height of the lower opening of the second liquid extraction pipe 42, and the lower end of the return pipe 6 is detachably connected to a spray head 61 for dispersing liquid;

[0047] The refluxed fertilizer solution is sprayed in a dispersed state onto the liquid surface above the fertilizer solution chamber through the spray head 61, so that the refluxed liquid and the fertilizer solution in the chamber can fully contact and mix, and the liquid in the fertilizer solution chamber can form an orderly convection circulation in the vertical direction, effectively eliminating the stratification phenomenon and further improving the uniformity of fertilizer solution concentration.

[0048] Preferably, the static mixer 2 includes a housing 21, a drug outlet pipe 22 and a drug outlet 27. The drug outlet pipe 22, which communicates with the inside of the drug liquid pipe 8, is fixed inside the housing 21. A mixing channel is formed between the drug outlet pipe 22 and the housing 21. The upper end of the side wall of the drug outlet pipe 22 is provided with a drug outlet 27 for uniformly spraying out the drug liquid.

[0049] The liquid medicine is evenly sprayed radially from multiple outlets 27 at the upper end of the side wall of the outlet pipe 22 into the mixing channel, so that the liquid medicine is dispersed in the form of fine droplets in the flowing fertilizer and water mixture system. No additional mixing container or stirring component is required, which reduces the overall size and manufacturing cost of the device.

[0050] Preferably, the top end of the dispensing tube 22 is integrally formed with a conical block 26 for dispersing liquid, and a liquid guiding block 23 is provided on the inner wall of one end of the shell 21 corresponding to the conical block 26;

[0051] After being guided by the liquid guide block 23, the fertilizer solution and water solution mixture impacts the surface of the conical block 26 at high speed. Under the impact force, the mixture is forcibly dispersed, sheared, and re-aggregated, achieving a one-time enhanced mixing. At the same time, the corresponding arrangement of the conical block 26 and the liquid guide block 23 causes a sharp change in the cross-section of the liquid flow channel, generating local turbulence and eddy current effects, which further promotes the uniform mixing of fertilizer solution and water solution at the molecular level and significantly improves the mixing quality.

[0052] Preferably, the inner wall of the mixing channel is provided with a first threaded portion 24, and the outer wall of the drug outlet tube 22 is provided with a second threaded portion 25 along its axial direction, the second threaded portion 25 having the opposite rotation direction to the first threaded portion 24;

[0053] When the mixture flows axially along the mixing channel, under the combined guiding action of the first threaded part 24 and the second threaded part 25 with opposite rotation directions, the liquid flow direction is forced to change repeatedly and generate multiple streams with different directions. When the liquid in the adjacent channels flows out of the threaded area, multiple streams of fluid collide and self-mix, which can achieve efficient and thorough mixing of liquid without the need for external power, effectively ensuring the consistency of the output fertilizer and medicine concentration.

[0054] Preferably, the fertilizer solution pipe 7 has a second flow meter 71;

[0055] The output flow rate of the fertilizer solution can be monitored in real time. Operators can accurately adjust the mixing ratio of fertilizer solution and pesticide solution based on the feedback data from the second flow meter 71 and the data from the first flow meter 93 to ensure that the output mixed solution has a stable and accurate concentration.

[0056] Preferably, the lower end of the static mixer 2 is fixed with a connecting pipe 13 that connects to the outside;

[0057] The uniformly mixed liquid medicine or fertilizer solution can be easily connected to the external spray pipe or drip irrigation pipe by the static mixer 2, thereby achieving rapid connection with the existing irrigation system in the field.

[0058] The working principle and usage process of this invention are as follows: During use, a high-concentration fertilizer solution is added to the inside of the tank 1 through the second inlet 12. At this time, the second pump 41 draws the fertilizer solution through the second extraction pipe 42, allowing it to flow into the return pipe 6 via the three-way valve 5. The fertilizer solution is then dispersed by the spray head 61 to improve the mixing uniformity of the fertilizer in the fertilizer solution chamber and reduce stratification. When it is necessary to spray or drip-irrigate crops with fertilizer and pesticide solutions, the second pump 41 draws the high-concentration fertilizer solution, which flows into the static mixer 2 through the three-way valve 5 and the fertilizer solution pipe 7. Simultaneously, a high-pressure water pipe connected to the water inlet pipe 3 injects water into the static mixer 2. The high-concentration fertilizer solution and water are guided by the guide block 23 and impact the conical block 2. 6. The surface is mixed. When moving along the mixing channel axially, it is guided by the second threaded part 25 and the first threaded part 24 with opposite rotation, realizing self-intersecting mixing and improving the mixing uniformity. Finally, it flows into the connecting pipe 13. The connecting pipe 13 is used to connect to the external spray pipe or drip irrigation pipe to fertilize the crops. When fertilizing and applying pesticides at the same time, the pesticide solution is drawn into the inside of the pesticide solution pipe 8 by the first pump body 92 and sprayed out from multiple pesticide outlets 27 through the pesticide outlet pipe 22. The fertilizer solution and water solution that flow into the inside of the shell 21 through the fertilizer solution pipe 7 and the water inlet pipe 3 meet and mix. Finally, it can also be discharged to the outside through the connecting pipe 13. Similarly, crops can be treated separately to verify the effect of different pesticide solutions on crops.

[0059] 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.
