Abstract
Description
Technical Field
[0001] This invention relates to the field of agricultural equipment, specifically to a method, system, equipment, and medium for side conveying of solid fertilizer. Background Technology
[0002] In orchard production management, fertilization is a crucial operational step that directly affects fruit yield and fruit quality. Rational fertilization is an important measure to ensure high, stable, and increased fruit production. Among various fertilization methods, basal fertilizer accounts for more than 70% of the total fertilizer application. However, with increasing demands for fruit quality and taste, traditional hole application of organic fertilizer is becoming increasingly important.
[0003] Research on orchard hole-planting machinery has largely focused on posthole diggers. Posthole diggers can be categorized based on their power system connection methods into handheld, suspended, towed, and self-propelled types. Generally speaking, posthole diggers suffer from low automation and cannot simultaneously perform tasks such as digging holes, fertilizing, applying pesticides, and covering with soil.
[0004] Therefore, automated solid fertilizer delivery is a key link in the hole application process. The hole application process for fruit trees achieves deep drilling through hole application tools. It is impossible to achieve precise fertilization of the drilled hole by gravity drive above the hole application tools.
[0005] Currently, deep soil fertilization in orchards primarily utilizes gravity-driven fertilization. While this method achieves deep fertilization under gravity, it lacks quantitative processing and falls under the category of random fertilization. For example, patent publication CN 117223455A discloses a soil fertilizer for landscaping that uses a funnel structure for fertilizer delivery, utilizing gravity for fertilization; patent publication CN 117598080A discloses a deep-penetration fertilization device for agricultural planting, where the fertilizer delivery pipe is inserted deeply into the soil using downward impact force, and the fertilizer is applied through gravity. Both patents achieve automatic fertilizer dispensing through gravity-driven methods.
[0006] The fertilizer application process is automated by gravity drive. However, this method lacks quantitative control, resulting in poor uniformity of fertilizer application. Furthermore, the absence of quantitative control mechanisms such as hoppers and gravity sensors leads to random fertilization, which not only wastes fertilizer but may also cause adverse effects such as seedling burn.
[0007] To address the aforementioned issues, and based on the needs of orchard hole application, the fertilizer delivery process utilizes gravity drive while employing structures such as hoppers and conveying troughs to achieve quantitative fertilizer application. Continuous or intermittent delivery methods can be used to achieve uniform fertilizer delivery. For example, patent publication number CN 117204184A discloses a seedling root fertilization device suitable for hole application, in which a sprocket drives a hopper to pour fertilizer into a conveying pipe, utilizing gravity for fertilization. Patent publication number CN 117441463A discloses a fertilization device for crops, in which a rotating mechanism intermittently and quantitatively inputs fertilizer into a conveying trough, and then discharges it from the trough into a riser pipe for fertilization. These technical solutions utilize hoppers and conveying troughs to achieve quantitative fertilization during the fertilizer delivery process.
[0008] While the aforementioned technologies achieve quantitative fertilizer delivery through hoppers and conveyor troughs, and apply fertilizer in holes under gravity, the hoppers and conveyor troughs are fixed structures, resulting in a fixed amount of fertilizer delivered per batch. Hole application in orchards is a variable fertilization method tailored to different tree shapes and species. Technology Scheme Two cannot adjust the amount of fertilizer applied per hole according to different needs, leading to issues of excessive fertilizer application for some tree species and insufficient fertilizer application for others.
[0009] To address the varying fertilizer requirements of different plants and the same plant at different growth stages, existing technologies employ variable-control fertilization methods using fans, spiral ejection structures, and other techniques. For example, patent publication number CN 117356416A describes a side-mounted wind-powered fertilization device installed on a rice transplanter. This device uses a fertilization fan unit as a power source to scatter and transport fertilizer, enabling surface fertilization of paddy fields. This method can also adjust the amount of fertilizer per unit area by changing the fertilization time.
[0010] In the above technologies, although variable control of fertilization can be achieved through fans, spiral ejection structures, etc., the influence of fertilizer particles is not considered. During the fertilization process, the power of the fans and spiral ejection structures cannot be adjusted for different fertilizer particles. Therefore, it is impossible to accurately control the fertilization area of the fertilizer during particle changes. For hole application, different particle sizes will cause the fertilizer to not accurately enter the fertilization hole. Summary of the Invention

Detailed Implementation
[0054] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

Rather, the use of words such as "illustrative," "for example," or "for example" is intended to present the relevant concepts in a specific manner.
[0056] In the description of the embodiments of this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, B existing alone, or A and B existing simultaneously. Furthermore, unless otherwise stated, the term "multiple" means two or more. For example, multiple systems refer to two or more systems, and multiple screen terminals refer to two or more screen terminals. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. The terms "comprising," "including," "having," and their variations all mean "including but not limited to," unless otherwise specifically emphasized.
[0057] With increasing demand for higher quality and better taste in fruit, traditional organic fertilizer application in holes is becoming increasingly important. The hole application process in orchards involves variable application based on the type and shape of the fruit trees. To meet the requirements of variable hole application for fruit trees, this patent mainly invents a solid fertilizer delivery system mounted on the chassis of a hole application machine. After drilling, the system can precisely apply fertilizer to the drilled holes and accurately control the amount of fertilizer applied.
[0058] In fruit tree fertilization, deep drilling is achieved using a fertilization cutter. However, precise fertilization through gravity-driven drilling cannot be achieved above the cutter. While hollow fertilization cutters can be developed for gravity-driven drilling and precise fertilization via a central hole, this is not feasible for small-diameter holes. Furthermore, the hollow structure significantly reduces the cutter's yield strength, increasing the risk of breakage during deep fertilization. During fertilization above the cutter, solid fertilizer collides with the cutter surface, causing interference and hindering precise entry into the hole. To address the strength issues of the fertilization cutter and the interference problem during solid fertilizer application, this patent develops a device mounted on the side of the fertilization cutter. After drilling, the cutter is raised to its highest position, at which point a blower throws solid fertilizer into the hole from the side.
[0059] The proper nouns used in this application include:
[0060] Hole applicator: A hole applicator is an agricultural machine mainly used to apply fertilizer to predetermined planting locations or planting holes during crop planting or growth. This fertilization method is called spot application or hole application. Compared with traditional strip fertilization, hole application can more accurately apply fertilizer near the crop roots, thereby improving fertilizer utilization and crop yield. Hole applicators are designed and functionally diverse, including but not limited to integrated water and fertilizer precision hole applicators, no-till seeders, precision hole fertilization systems, and deep-application inclined liquid fertilizer hole applicators. These devices can achieve precise fertilization according to different crops and soil conditions.
[0061] The working principle of a hole applicator is mainly to dig holes of a certain size and depth using hole applicators, and then apply fertilizer into these holes. For example, the operation process of a high-efficiency hole applicator integrating water and fertilizer includes filling the fertilizer tank and water tank with fertilizer and water respectively, adjusting the engine through a control device to rotate the hole-digging cutter head, thereby realizing the hole-digging function.
[0062] Classification decision: In machine learning, this refers to the process of classifying data using algorithms. Decision trees are a commonly used classification algorithm that classifies data by recursively dividing a dataset into subsets and training a base classifier for each subset.
[0063] Reference Figure 1 and Figure 2 A method for side conveying of solid fertilizer includes the following steps:
[0064] S11: Obtain fertilizer granule parameter information;
[0065] Specifically, due to the diversity of fertilizers used in fertilization, the granules of various fertilizers also differ greatly. The distinguishing features that affect the solution of this application are summarized by fertilizer granule parameter information. The fertilizer granule parameter information specifically includes the mass of a single fertilizer granule, the diameter of a single fertilizer granule, and the number of granules passing through the cross-section of the transmission pipe at one time during fertilization. The fertilizer granule parameter information is obtained by personnel inputting it into a smart terminal, which can be a computer or an MCU. In other embodiments, the fertilizer granule parameter information can also be obtained by scanning a QR code or text information provided by the manufacturer.
[0066] S12: Obtain fruit tree image information, extract tree shape feature information from the fruit tree image information according to the preset feature extractor, and determine the fertilizer application amount and transmission hole depth associated with the tree shape feature information;
[0067] Specifically, the image devices installed on both sides of the hole-applying machine, such as cameras, capture images of the objects to be fertilized. The feature extractor uses existing image feature extraction algorithms. The smart terminal extracts images of the tree trunk and tree crown from the images and calculates tree shape feature information such as trunk diameter and crown size from the images. After obtaining the tree shape feature information, a classification decision is made to obtain the hole-applying blade's digging depth and the amount of fertilizer to be applied. Then, the smart terminal drives the hole-applying machine to drill holes in the ground near the fruit trees according to the hole-applying blade's digging depth.
[0068] In other embodiments, the tree-shaped feature information can also be obtained by human input into a smart terminal.
[0069] S20: Determine the parameters of the fertilizer horizontal transport model;
[0070] Specifically, the parameters of the fertilizer horizontal transport model include η, η1, P, and d. A h, m A n A , g and L; where m A n A d A For fertilizer granule parameter information, m A For the mass of a single fertilizer pellet, n A The number of particles passing through the cross-section of the conveying pipe in a single pass, d A η is the diameter of a single fertilizer pellet; L is the distance from the feed pipe opening to the center of the borehole; h is the distance from the feed pipe opening to the top of the borehole opening; η is the working efficiency of the blower; P is the power of the blower; η1 is the power transmission efficiency within the feed pipe; g is the gravity coefficient; in this embodiment, L and h are fixed values.
[0071] S21: Input the fertilizer granule parameter information into the fertilizer horizontal transmission model to obtain the fan speed information;
[0072] Specifically, the fertilizer horizontal transport model is as follows:
[0073]
[0074] Where V is the fan speed, the specific principle by which the fertilizer horizontal transport model determines the fan speed is as follows:
[0075] According to the formula: We can obtain: Within time t, the distance the particle travels in the horizontal direction is L, which can be calculated as follows: Given the fan's efficiency η, rotational speed V, and power P; and considering the number of particles ejected from the feed pipe within a unit time t1, the answer is: The useful power output of the fan is η×P, while the power transmission efficiency in the duct is η1;
[0076] At this point, the total power obtained by the particle is η×η1×P, and the total work done by the particle per unit time is... Will Substitution The output speed is calculated as follows:
[0077] To ensure that solid fertilizer granules are thrown into the center of the upper end face of the drill hole, the output velocity of the granules at the pipe opening needs to be increased. Organized Square root of both sides Finally, the rotational speed of the constant power output fan was determined to be:
[0078]
[0079] Once the type of fertilizer to be applied is determined, the required speed V of the blower can be automatically calculated, and precise fertilization of the drill hole can be achieved by controlling the speed V.
[0080] In other embodiments, the fertilizer horizontal transport model can also be a trained neural network model;
[0081] S31: Set the fan speed according to the fan speed information so that the fertilizer granules are transported from the horizontal conveying pipe to the center of the drilling hole;
[0082] Specifically: After the intelligent terminal calculates the fan speed information through the fertilizer horizontal transmission model, it sets the fan speed on both sides of the hole applicator to be the same as the fan speed information value, so that the fertilizer granules can be horizontally sprayed from the pipe opening of the conveying pipe at the desired speed and then accurately fall into the center of the hole, thereby completing the precise delivery of fertilizer granules.
[0083] S41: Obtain fertilizer gravity information;
[0084] Specifically, the fertilizer gravity information is collected by a gravity sensor used to weigh the fertilizer on the hole applicator, which represents the total weight of the fertilizer on the hole applicator. After the gravity sensor collects the fertilizer gravity information, it transmits the fertilizer gravity information to the smart terminal.
[0085] S42: Determine if the fertilizer gravity information is below the threshold; if so, shut down the fan.
[0086] Specifically: In this embodiment, the threshold represents the gravity before fertilizer transmission minus the amount of fertilizer applied. It should be noted that the amount of fertilizer applied represents the amount of fertilizer needed by the current fruit tree. When the total gravity of the transmitted fertilizer particles reaches the amount of fertilizer applied, and the fertilizer gravity information drops below the threshold, the smart terminal will turn off the fan to complete the fertilization of the current fruit tree.
[0087] The implementation principle of the solid fertilizer side conveying method provided in this embodiment is as follows: Appropriate fertilizer is manually loaded according to the growth stage and characteristics of the fruit trees, and the type of fertilizer to be applied is manually selected. After the fertilizer type is selected, information such as the mass of a single fertilizer pellet, the diameter of a single fertilizer pellet, and the number of pellets passing through the pipe cross-section in a single pass can be obtained. After the manual information settings are completed, the image devices on the left and right sides of the hole applicator respectively collect the tree shape characteristics of the fruit trees to be fertilized on both sides. Based on the tree shape characteristics, including trunk diameter and crown size, classification decisions are made to determine the hole-digging depth of the hole applicator and the amount of fertilizer applied. The solid fertilizer conveying system obtains the hole-digging depth of the hole applicator and the amount of fertilizer applied. After receiving the hole-digging operation completion signal, the solid fertilizer conveying system proceeds according to: (Once the application equipment, blower, conveying pipe, and fertilizer type are determined, η, η1, P, d) A h, m A n A (g and L are fixed values) drive the fan to maintain this speed. Solid fertilizer is thrown into the drill hole;
[0088] Gravity sensors monitor the change in the total weight of the fertilizer in real time. When the gravity sensor detects that the amount of fertilizer applied has reached the decision value, the fans on both sides are turned off, and the fertilizer application is completed. Fertilizer is manually loaded according to the growth stage and characteristics of the fruit trees, and the type of fertilizer to be applied is manually selected as shown in Table 1. After selecting the fertilizer type, information such as the weight of a single fertilizer pellet, the diameter of a single fertilizer pellet, and the number of pellets passing through the pipe cross-section in a single pass can be obtained. After manual information settings are completed, the image devices on the left and right sides of the hole applicator collect the tree shape characteristics of the fertilized fruit trees on both sides. Based on the tree shape characteristics, including trunk diameter and crown size, classification decisions are made to determine the hole-digging depth of the hole applicator and the amount of fertilizer applied. The solid fertilizer conveying system acquires the hole-digging depth of the hole applicator and the amount of fertilizer applied. After receiving the signal that the hole-digging operation is complete, the solid fertilizer conveying system... (Once the application equipment, blower, conveying pipe, and fertilizer type are determined, η, η1, P, d) A h, m A n A (where g and L are fixed values) drive the blower to maintain this speed. Solid fertilizer is thrown into the drill hole. When the gravity sensors on both sides detect that the amount of fertilizer applied has reached the decision value, the blowers on both sides are turned off, and the fertilizer application is completed.
[0089] Reference Figure 3 This application also provides a system for a side-conveying method of solid fertilizer, comprising:
[0090] Information acquisition module 14 is used to acquire fertilizer granule parameter information;
[0091] The processing module 15 is used to input fertilizer granule parameter information into the fertilizer horizontal transmission model to obtain fan speed information; the control module 16 is used to set the fan speed according to the fan speed information so that the fertilizer granules are transmitted from the horizontal conveying pipe to the center of the drilling hole.
[0092] A third aspect of this application also provides a solid fertilizer side conveying device.
[0093] Reference Figure 4 and Figure 5 A solid fertilizer side conveying device includes a support frame 1, a material bucket 2, an intelligent terminal for performing the solid fertilizer side conveying method as described above, and a fertilizer granule conveying mechanism controlled by the intelligent terminal.

[0094] Two sets of fertilizer granule conveying mechanisms are symmetrically arranged in the horizontal direction. Each fertilizer granule conveying mechanism includes a stirring motor 3, a stirring shaft 4, a conveying fan 5, and a conveying pipe 6. The stirring shaft 4 is driven by the stirring motor 3 to rotate and stir the fertilizer granules in the hopper 2. The stirring motor 3 is coupled to a smart terminal for control. A reduction gearbox 7 is fixedly installed inside the hopper 2. The two sets of fertilizer granule conveying mechanisms share a stirring motor 3. The stirring motor 3 drives the two stirring shafts 4 to rotate slowly through the reduction gearbox 7 to stir the fertilizer granules in the hopper 2 and keep them in a loose state. A pressure cover 8 is fixedly connected to the reduction gearbox 7 to prevent fertilizer from entering the reduction gearbox 7. The storage space inside the hopper 2 is divided into left and right parts by the reduction gearbox 7, and the two stirring shafts 4 are located in the left and right storage spaces respectively.
[0095] The output end of the conveying pipe 6 is horizontal; the output end of the conveying pipe 6 faces the aperture knife 9; the conveying pipe 6 is sleeved on the air outlet of the conveying fan 5, and the air inlets of the two conveying fans 5 are respectively connected to the left and right storage spaces in the material bucket 2 to respectively suck up the fertilizer particles in the left and right storage spaces. A gravity sensor for detecting the weight of fertilizer particles is fixedly installed in the material bucket 2. The gravity sensor is coupled to the smart terminal for transmitting fertilizer gravity information to the smart terminal. The gravity sensor can be a piezoresistive gravity sensor. The gravity sensor includes a left gravity sensor 10 and a right gravity sensor 12. The left gravity sensor 10 and the right gravity sensor 12 are respectively located in the left and right storage spaces. A left tray 11 is placed above the left gravity sensor 10, and a right tray 13 is placed above the right gravity sensor 12.
[0096] It should be noted that since the height of the output port of the conveying pipe 6 from the ground and the distance of the hole-applying blade 9 are fixed after the solid fertilizer side conveying equipment is installed on the hole applicator, L and h are fixed values.
[0097] The implementation principle of the solid fertilizer side conveying device provided in this embodiment is as follows: By using the side-applying method of this solid fertilizer side conveying device, the spatial interference problem between the cutting tool and the fertilizer conveying equipment in the fruit tree hole application process is solved. Adopting the side-applying fertilizer method eliminates the need for axial hollowing modification of the hole-applying blade 9, ensuring the rigidity of the blade regardless of its size. Furthermore, the symmetrical fertilizer particle conveying mechanism on both sides allows for independent operation on both sides, satisfying simultaneous fertilization from both sides and improving fertilization efficiency.
