Description

Technical Field

[0001] This utility model relates to the field of fertilization device technology, and in particular to a quantitative fertilization device for the rhizosphere of fruit trees. Background Technology

[0002] In the field of water-soluble fertilizer application in agricultural machinery, topdressing guns are already widely used. Farmers only need to mix fertilizer and water, and then, combined with a pressure pump, inject the dissolved fertilizer solution into the ground through the topdressing gun. The plants absorb the dissolved fertilizer and pesticide solution and grow well. This saves time and effort for users and promotes the advancement of agricultural fertilization technology.

[0003] In existing technologies, because users cannot accurately control the amount of fertilizer applied through the equipment itself during actual application of topdressing guns, they can only rely on personal experience to make manual adjustments. This leads to excessive fertilizer application in some areas, resulting in resource waste, while insufficient fertilizer application in other areas affects crop growth. Uneven fertilization and pesticide application not only significantly reduces fertilizer utilization but also directly increases the input costs of agricultural production. Long-term reliance on experience-based operation may also lead to derivative problems such as soil nutrient imbalance and environmental pollution, further restricting the sustainability of agricultural production. Therefore, it is necessary to improve the fruit tree rhizosphere quantitative fertilization device to solve the above problems. Utility Model Content

[0004] In order to overcome the problem that in actual application, users cannot accurately control the amount of fertilizer applied through the equipment itself and can only rely on personal experience to make manual adjustments, resulting in uneven fertilization and pesticide application, which not only significantly reduces fertilizer utilization but also directly increases the input costs of agricultural production.

The quantitative water flow control device is fixedly connected to the handle, and a barrel is fixedly connected to the handle. A water outlet assembly for discharging water is provided on the barrel. A connecting pipe is fixedly connected to the inner side of the barrel, and a second fixing seat is fixedly connected to the connecting pipe. A first fixing seat is fixedly connected to the connecting pipe, and a mounting bracket is fixedly connected to the end of the first fixing seat away from the second fixing seat. A small motor is fixedly connected to the mounting bracket, and the small motor is electrically connected to... A worm gear is fixedly connected to a small motor connected to a water flow metering electrical control device. A worm wheel meshes with the outside of the worm gear, and a rotating rod is fixedly connected inside the worm wheel. The rotating rod is rotatably connected inside a first fixed seat, a second fixed seat, and a connecting pipe. A baffle is provided on the rotating rod to switch the flow inside the connecting pipe. A sealing ring is fixedly connected to the outside of the baffle. A stop block is fixedly connected to the inner wall of the connecting pipe. A water flow detection device for detecting the flow inside the connecting pipe is fixedly connected to the bottom of the stop block. The water flow detection device is electrically connected to the water flow metering electrical control device.

[0011] As a preferred option, five sets of water outlets are provided, which are distributed alternately from top to bottom on the hollow rod.

[0012] The beneficial effects of this utility model are:

[0013] 1. By inputting the water flow detection device's signal value into the water flow quantitative control device, the water consumption is controlled to rotate the baffle, allowing liquid fertilizer to be delivered.

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] In the process of agricultural modernization, the innovation of fertilization technology has always been a core element in improving crop yield and quality. Traditional fertilization methods have problems such as low nutrient utilization, high labor intensity, and high environmental pollution risks, while the application of water-soluble fertilizer technology and topdressing guns has brought breakthroughs to the field of agricultural fertilization.

[0027] Water-soluble fertilizers, as a type of multi-element compound fertilizer that is completely soluble in water, have advantages such as comprehensive nutrients, high absorption rate, and convenient application. Their application techniques have evolved from simple fertigation to precision drip irrigation. Early methods involved direct fertigation, but due to the high nutrient content of water-soluble fertilizers, direct fertigation easily caused seedling burn, root damage, and weak seedlings. To solve this problem, the two-stage dilution method has gradually been promoted. This method not only facilitates uniform fertilizer application but also improves fertilizer utilization. At the same time, the principle of applying small amounts frequently aligns with the continuous nutrient absorption characteristics of plant roots, effectively reducing leaching losses caused by large-scale, one-time fertilization.

[0028] In terms of irrigation facilities, drip irrigation fertilization technology has become an important method for applying water-soluble fertilizers. When using drip irrigation, first drip clean water until the pipes are full, then begin fertilizing. After fertilization, immediately drip clean water for 20-30 minutes to flush out any remaining fertilizer solution from the pipes. In principle, the slower and more even the fertilization, the better, especially for elements with poor mobility in the soil (such as phosphorus). Extending the fertilization time can effectively improve nutrient utilization. Because different crops have significantly different root depths, excessive irrigation not only wastes water but also causes nutrients to leach below the root zone, resulting in fertilizer waste.

[0029] Topdressing gun fertilization uses a fertilizer applicator to directly inject the necessary nutrients and energy elements into the plant's root zone, achieving concentrated, precise, and balanced nutrient supply. The application of topdressing guns solves many traditional fertilization problems. In some enclosed orchards and greenhouse vegetable growing areas, manual digging for fertilizer is extremely inconvenient, and spreading fertilizer results in significant loss and low utilization. The use of fertilizer applicators effectively solves these problems. It can also apply rationally formulated fertilizers according to scientific fertilization schedules, achieving integrated water and fertilizer management and providing complete nutrients.

[0030] Fruit tree root systems have unique distribution characteristics. Their horizontal roots are generally concentrated around or slightly beyond the canopy projection, and they exhibit a tendency to grow towards fertile areas, often shifting their growth direction based on the location of fertilization. Therefore, when fertilizing the soil, it is essential to apply fertilizer to the root zone where it is concentrated, based on these characteristics, to facilitate root absorption and maximize fertilizer effectiveness.

[0031] Fruit trees have different nutrient requirements at different growth stages. For example, precise nutrient supply is needed during critical periods such as flower bud differentiation and fruit enlargement. Water is also crucial for fruit tree growth, as it is essential for photosynthesis, transpiration, nutrient transport, and metabolism. Proper irrigation has many beneficial effects on fruit trees, while improper irrigation can lead to problems such as ground erosion, damage to soil structure, nutrient loss, soil salinization, and imbalanced fruit tree growth.

[0032] Traditional fertilization methods mainly include broadcasting and fertigation. Broadcasting involves evenly spreading fertilizer on the soil surface and then mixing it into the soil through tilling. This method is simple to operate, but it suffers from significant nutrient loss and low fertilizer utilization. Fertigation, on the other hand, involves dissolving fertilizer in water and applying it to the soil along with irrigation water. While fertigation can improve the rate of fertilizer dissolution and absorption, it also suffers from nutrient leaching loss, especially under conditions of heavy flooding, where nutrients are easily lost below the root zone, preventing crops from fully absorbing them.

[0033] The application of fertilizer spraying guns has solved many traditional fertilization problems. In some enclosed orchards and greenhouse vegetable growing areas, manual digging for fertilizer is extremely inconvenient, and spreading fertilizer results in significant loss and low utilization. Fertilizer spraying guns solve these problems. They can also apply fertilizer according to scientifically prescribed times, achieving integrated water and fertilizer management and providing complete nutrients. The advantages of fertilizer spraying guns are even more pronounced under special environmental conditions. For example, in winter greenhouse fruit and vegetable cultivation, facing problems such as low temperatures, insufficient sunlight, and high humidity, traditional cultivation methods cannot irrigate or fertilize. However, fertilizer spraying gun technology allows farmers to apply fertilizer and supplement nutrients in a timely manner without increasing humidity inside the greenhouse, greatly reducing the occurrence of diseases, reducing pesticide investment, and lowering pesticide residues, meeting national green and organic agricultural production technology standards.

[0034] Topdressing gun fertilization technology has significant advantages over traditional fertilization methods, but it also has some limitations. Regarding its advantages, as mentioned earlier, it improves fertilization efficiency, reduces labor intensity, achieves integrated water and fertilizer management, and increases fertilizer utilization. However, topdressing gun fertilization technology also has some drawbacks. First, the fertilization precision is relatively low, relying mainly on manual operation and experience-based judgment, making it difficult to achieve precise quantitative fertilization. Second, in complex terrain and large-scale orchards, the operation is more difficult, and the labor intensity remains high. Furthermore, topdressing gun fertilization technology requires a high level of skill from operators, necessitating specialized training to master.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] Please see Figure 1 - Figure 7This utility model provides an embodiment: a quantitative fertilization device for the root zone of fruit trees, including a gun handle 1, a water flow quantitative electrical control device 21, and a water outlet component. The water flow quantitative electrical control device 21 is fixedly connected to the gun handle 1, and a gun barrel 22 is fixedly connected to the gun handle 1. A water outlet component for discharging water is provided on the gun barrel 22. A connecting pipe 23 is fixedly connected to the inner side of the gun barrel 22, a second fixing seat 25 is fixedly connected to the connecting pipe 23, and a first fixing seat 24 is fixedly connected to the connecting pipe 23. The end of the first fixing seat 24 away from the second fixing seat 25 is fixedly connected to an installation... A small motor 28 is fixedly connected to a mounting bracket 26. The small motor 28 is electrically connected to a water flow metering control device 21. A worm gear 29 is fixedly connected to the small motor 28. A worm wheel 210 meshes with the worm gear 29. A rotating rod 211 is fixedly connected inside the worm wheel 210. The rotating rod 211 is rotatably connected inside the first fixed seat 24, the second fixed seat 25, and the connecting pipe 23. A baffle 212 is provided on the rotating rod 211 to switch the flow rate inside the connecting pipe 23. A sealing ring 213 is fixedly connected to the outside of the baffle 212. A stop block 214 is fixedly connected to the inner wall of the connecting pipe 23. A water flow detection device 216 for detecting the flow rate inside the connecting pipe 23 is fixedly connected to the bottom of the stop block 214. The water flow detection device 216 is electrically connected to the water flow metering control device 21. By inputting the signal value of the water flow detection device 216 into the water flow metering control device 21, the water flow is controlled to rotate the baffle 212, allowing the liquid fertilizer to be transported. When the water flow detection device 216 fixed at the bottom of the stop block 214 detects a certain water flow, it feeds back to the water flow metering control device 21. The control device 21 resets the baffle 212 and seals the connecting pipe 23, allowing the liquid fertilizer supply cycle to start under the command of the water flow quantitative control device 21. This makes the operation convenient and allows for precise quantitative application of liquid fertilizer without relying on personal experience for manual adjustment, improving the uniformity of fertilization and increasing fertilizer utilization. The water outlet component determines the insertion depth of the hollow rod 31 by inserting it into the soil and contacting the ground through the pedal 32, thus improving its adaptability to fertilization at different depths and increasing fertilizer utilization.

[0037] Please see Figure 2 - Figure 5In this embodiment, the rotating rod 211 has a corresponding groove at the corresponding position of the baffle 212. The baffle 212 is set in the groove of the rotating rod 211, making it easy to install the baffle 212 on the rotating rod 211, thus improving the practicality of the device. A semi-circular block 27 is fixedly connected to the end of the mounting bracket 26 away from the second fixed seat 25. The worm gear 29 is rotatably connected to the inside of the semi-circular block 27. The inside of the baffle 212 is provided with a mounting bolt 215, which is threaded to the inside of the rotating rod 211. The water consumption value is controlled by inputting the signal from the water flow detection device 216 into the water flow quantitative electrical control device 21, which controls the baffle 212 to rotate, allowing the liquid fertilizer to be transported. The bottom of the block 214 is also affected. When the fixed water flow detection device 216 detects a certain water flow, it feeds back to the water flow quantitative control device 21, resetting the baffle 212 and sealing the connecting pipe 23. Under the command of the water flow quantitative control device 21, it can start each liquid fertilizer supply cycle, making it easy to operate and allowing for precise quantitative application of liquid fertilizer without relying on personal experience for manual adjustment, thus improving the uniformity of fertilization and increasing fertilizer utilization. The baffle 212 has corresponding through holes at the positions of the mounting bolts 215. The mounting bolts 215 are set inside the through holes of the baffle 212, allowing the baffle 212 to be easily installed and fixed, thereby improving the cleaning effect of the baffle 212.

[0038] Please see Figure 6 - Figure 7 In this embodiment, the water outlet assembly includes a hollow rod 31, which is mounted on a gun barrel 22. A limiting plate 35 is slidably connected inside the gun barrel 22, and a locking block 34 is fixedly connected to the outside of the limiting plate 35. The locking block 34 is slidably connected inside the gun barrel 22 and engages with the inside of the hollow rod 31. A spring 36 is fixedly connected between the limiting plate 35 and the gun barrel 22. A water outlet 33 for fertilizing the root zone of the fruit tree is provided on the hollow rod 31. A pedal 32 is slidably connected to the hollow rod 31, and a fixing bolt 37 is threaded inside the pedal 32. The fixing bolt 37 is in contact with the hollow rod 31. By moving the hollow rod 31... Inserted into the soil, the hollow rod 31 is contacted with the ground via the pedal 32 to determine the insertion depth, thus improving its adaptability to fertilization at different depths and increasing fertilizer utilization. The outer shape of the locking block 34 is semi-circular, and the hollow rod 31 has a corresponding locking hole at the corresponding position of the locking block 34. The locking block 34 is engaged inside the locking hole of the hollow rod 31, making it easy to install and fix the hollow rod 31, improving the practicality of the device. Five sets of water outlets 33 are provided, which are staggered from top to bottom on the hollow rod 31, making it convenient to fertilize the root zone of fruit trees and improving fertilization efficiency.

[0039] During operation, pressing the locking blocks 34 on both sides of the barrel 22 inward compresses the spring 36, causing it to fit the hollow rod 31 onto the barrel 22. Then, by finely adjusting the position of the hollow rod 31, the locking blocks 34 on both sides are engaged with the locking holes of the hollow rod 31, thus securing the hollow rod 31. Next, the tip of the hollow rod 31 is inserted into the ground. The pedal 32 slides within the corresponding groove of the hollow rod 31. Then, by rotating the fixing bolt 37, it is threaded into the pedal 32, pressing against the hollow rod 31 to fix the height of the pedal 32. Finally, the pedal is pressed down by foot. The pedal 32 inserts the hollow rod 31 into the soil. The insertion depth of the hollow rod 31 is determined by the contact between the pedal 32 and the ground, improving its adaptability to different fertilization depths. An external water pipe is installed on the handle 1, and a pump on the external water pipe extracts the stored fertilizer solution. The water usage is controlled by inputting a signal from the water flow metering control device 216 into the water flow metering control device 21. The water flow metering control device 21 then instructs the small motor 28 to start, causing it to drive the worm gear 29 to rotate inside the semi-circular block 27. This rotation is achieved through the meshing of the worm wheel 210 and the worm gear 29. The mechanism allows the baffle 212 to rotate 90 degrees within the first fixed seat 24, the second fixed seat 25, and the connecting pipe 23 via the rotating rod 211, facilitating fertilizer delivery. When the water flow detection device 216 fixed at the bottom of the abutment block 214 detects a certain water flow, it sends feedback to the water flow quantitative control device 21. The water flow quantitative control device 21 then controls the small motor 28 to rotate in the opposite direction, causing the baffle 212 to rotate in the opposite direction and come into contact with the abutment block 214. The sealing ring 213 improves the seal between the connecting pipe 23 and the baffle 212, completing the root zone fertilization of the fruit tree. The water flow metering electronic control device 21 allows for easy memorization of fertilizer application amounts. When fertilizing the root zone of another fruit tree, simply insert the hollow rod 31 into the root zone and press the cycle start button on the water flow metering electronic control device 21 to start the cycle, applying the same amount of fertilizer as the previous application. Under the command of the water flow metering electronic control device 21, each liquid fertilizer supply cycle can be started. The fertilizer enters the hollow rod 31 through the nozzle 22 and is applied to the soil through five sets of staggered water outlets 33. This makes the operation convenient and allows for precise quantitative application of liquid fertilizer.

[0040] Through the above steps, the water consumption is controlled by inputting the signal from the water flow detection device 216 into the water flow quantitative control device 21, causing the baffle 212 to rotate and allowing liquid fertilizer to be delivered. When the water flow detection device 216, fixed at the bottom of the block 214, detects a certain water flow, it sends feedback to the water flow quantitative control device 21, resetting the baffle 212 and sealing the connecting pipe 23. Under the command of the water flow quantitative control device 21, the liquid fertilizer supply cycle can be started. This solves the problem that users cannot accurately control the amount of fertilizer applied through the equipment itself and can only rely on personal experience to make manual adjustments, resulting in uneven fertilization and pesticide application. This not only significantly reduces fertilizer utilization but also directly increases the input costs of agricultural production.
