Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural machinery, and particularly relates to a liquid fertilizer spreading device based on pomegranate forest maintenance. Background Art

[0002] The maintenance of pomegranate forests has a crucial impact on the growth and yield of pomegranates. During the growth process of pomegranates, the reasonable application of liquid fertilizers can provide sufficient nutrients for them and promote the growth of pomegranate trees and fruit development.

[0003] To reduce the labor burden of workers, a liquid fertilizer spreading device is generally used. For example, a liquid fertilizer spraying device with the application number CN202111370730.7 can apply fertilizers in multiple directions simultaneously through the multi-directional spraying component provided. Through the moving wheels provided, it is convenient to move and push for fertilization. Through the mixing liquid storage tank provided, the stirring and configuration of liquid fertilizers can be carried out, which is convenient to control, and can move along the field for multi-directional spraying and fertilization, with strong practicability.

[0004] Although the liquid fertilizer spraying device in the above-mentioned comparative case can apply fertilizers, there are still some deficiencies in the actual use process: First, when the liquid fertilizer is directly sprayed on plants or into the air, under the action of high-temperature weather, its volatilization rate increases significantly, which not only causes a large amount of waste of fertilizers but also may produce unpleasant odors. Second, due to the lack of an appropriate adjustment mechanism, it is difficult to adjust the fertilization amount according to different soil fertilities, which is likely to lead to an excess of fertilizers in some areas, thus causing environmental pollution problems. Finally, the surface spraying method is difficult to meet the deep nutrient requirements of plants with deep root systems, such as pomegranate trees, which may affect the healthy growth of plants. Summary of the Invention

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

[0048] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in a preferred implementation manner" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or selectively exclusive embodiment with other embodiments.

[0049] Furthermore, the present invention is described in detail with reference to schematic diagrams. When detailing the embodiments of the present invention, for the sake of convenience in explanation, the cross-sectional views showing the device structures will be enlarged locally not in accordance with the general ratio, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0050] Please refer to the attached Figures 1 to 7 As shown, this embodiment provides a liquid fertilizer spreading device for pomegranate forest maintenance, including a base 1. A liquid storage tank 2 is fixedly installed at the upper end of the base 1, and a water pump 3 is fixedly installed on the side of the base 1;

[0051] A water pipe 4, which is fixedly connected to the water pump 3 and is used for transporting water source;

[0052] The support assembly 5 is installed on the base 1;

[0053] The spreading assembly 6 is arranged on the support assembly 5;

[0054] The medicine dispensing mechanism 7 is arranged on the base 1;

[0055] Among them, the medicine dispensing mechanism 7 includes a shunt pipe 71. Both shunt pipes 71 are connected to the water pipe 4. A driving part 72 is also arranged on the water pipe 4. Two linkage parts 73 are fixedly installed on the top surface of the base 1. Two quantitative medicine dispensing parts 74 are also fixedly installed on the base 1. A mixing part 75 is fixedly installed on the shunt pipe 71.

[0056] In this embodiment, the base 1 is fixed to an external mobile vehicle. The vehicle is equipped with a water storage tank which is communicated with the water inlet end of the water pump 3. The liquid medicine tank 2 is pre-filled with liquid medicine. During use, the water pump 3 is started to pump the water source in the water storage tank. The water source then flows along the water pipe 4 and finally sprays out from the spreading assembly 6. At the same time, the driving part 72 is driven during the flowing process of the water source. After the driving part 72 is started, it drives the quantitative medicine dispensing part 74 to operate through the linkage part 73, so as to realize quantitative medicine dispensing. Then, the medicine is mixed with the water source through the mixing part 75.

[0057] Secondly, please refer to Figures 1 to 5 again. The support assembly 5 includes a rotating rod 501. Both rotating rods 501 are rotatably connected to the base 1. A bracket 502 and a transmission gear 503 are fixedly installed on the rotating rod 501. A motor 504 is fixedly installed on the top surface of the base 1, and the output shaft of the motor 504 is fixedly connected to one of the rotating rods 501. A hydraulic electric push rod 505 is fixedly installed on the bracket 502. The telescopic end of the hydraulic electric push rod 505 is fixedly connected to an arc-shaped water storage box 506. A guide rod 507 is fixedly connected to the arc-shaped water storage box 506, and the guide rod 507 is slidably connected to the bracket 502.

[0058] In this embodiment, the device is placed around a tree by a moving vehicle body. Then, the motor 504 is started to drive one of the rotating rods 501 to rotate. The transmission gears 503 on the two rotating rods 501 mesh with each other to achieve the relative rotation of the two rotating rods 501. When the rotating rods 501 rotate relatively, the two brackets 502 are correspondingly unfolded. Next, the position of the device is adjusted to ensure that the two brackets 502 can surround the outer periphery of the tree. After that, the motor 504 is started again to rotate the two rotating rods 501 in the opposite direction, causing the two brackets 502 to close. In this way, the two brackets 502 can enclose the tree. Then, the hydraulic electric push rod 505 is controlled to extend, driving the arc-shaped water storage box 506 to move downward. During the downward movement of the arc-shaped water storage box 506, the sowing assembly 6 is driven to descend together. At the same time, the guide rod 507 fixed on the top surface of the arc-shaped water storage box 506 slides along the bracket 502, playing a role of guiding and limiting to ensure the stability of the lifting process of the arc-shaped water storage box 506.

[0059] Next, please refer to Figures 3 to 6 simultaneously. The sowing assembly 6 includes a hollow tube 601. The hollow tubes 601 are fixedly connected to the bottom surface of the arc-shaped water storage box 506 in an array distribution and are communicated with the arc-shaped water storage box 506. A water storage pipe 602 is fixedly sleeved on the outer wall of the hollow tube 601. Water outlet heads 603 are arranged on the water storage pipe 602 in an array distribution. Water outlet holes 604 are opened in an array distribution below the hollow tube 601. A ring 605 is fixedly connected to the inner wall of the hollow tube 601. Lifting rods 606 are slidably inserted into the ring 605 in a circumferential distribution. The upper end of the lifting rod 606 is fixedly connected with a piston plate 607. A compression spring 608 is fixedly connected to the bottom surface of the piston plate 607, and the lower end of the compression spring 608 is fixedly connected to the inner wall of the hollow tube 601. A round rod 609 is fixedly connected to the top surface of the piston plate 607. A sealing ring 610 is fixedly connected to the round rod 609 through a support rod, and the sealing ring 610 forms a sliding structure with the hollow tube 601. A connecting pipe 611 is connected between the adjacent water storage pipes 602 below the arc-shaped water storage box 506. One end of a telescopic hose 612 is connected to each of the two water storage pipes 602, and the other end of the telescopic hose 612 is connected to the water pipe 4.

[0060] In this embodiment, when the arc-shaped water storage box 506 starts to move downward, it will drive the hollow tube 601 to move downward together. As the hollow tube 601 descends, the water outlet holes 604 at its lower end will partially insert into the soil. Subsequently, the water pump 3 is started to draw water from the water storage tank. The drawn water starts to flow along the water pipe 4. During the flowing process, a part of the water source will be guided out through the shunt pipe 71, while the remaining water source continues to advance along the water pipe 4. These continuously flowing water sources will eventually flow into the water storage pipe 602 through the two telescopic hoses 612 connected to the end of the water pipe 4. Since each side of the water storage pipe 602 is connected to each other through the connecting pipe 611, the water source will flow from one water storage pipe 602 to another and finally flow into multiple water storage pipes 602. Each water storage pipe 602 is equipped with a water outlet head 603, and the water source is sprayed on the tree trunk through these water outlet heads 603. The sprayed water source will flow downward along the tree trunk and finally penetrate into the soil to provide the required moisture for the plants.

[0061] Secondly, please refer to again Figure 8 , the driving part 72 includes a hollow shell 721 which is fixedly connected to the water pipe 4. A first rotating shaft 722 is rotatably connected to the hollow shell 721 through a sealing bearing. A water wheel 723 is fixedly installed in the middle of the first rotating shaft 722. First linkage gears 724 and second linkage gears 725 are installed at both ends of the first rotating shaft 722.

[0062] In this embodiment, when the water source flows through the water pipe 4 and reaches the position of the driving part 72, with the rapid flow of the water, it will generate an impact force on the water wheel 723, prompting the water wheel 723 to rotate. Once the water wheel 723 starts to rotate, the first rotating shaft 722 also starts to rotate. As the first rotating shaft 722 rotates, it further drives the first linkage gears 724 and second linkage gears 725 connected to it, causing them to also start rotating.

[0063] Please refer to again Figure 7 , the linkage part 73 includes a support plate 731 which is fixedly connected to the top surface of the base 1. A second rotating shaft 732 is rotatably connected to the support plate 731. A third linkage gear 733 is fixedly installed at one end of the second rotating shaft 732, and a cam 734 is fixedly connected to the other end of the second rotating shaft 732.

[0064] In this embodiment, the first linkage gear 724 and the third linkage gear 733 are driven by a toothed belt, thereby driving the second rotating shaft 732 to rotate. The rotation of the second rotating shaft 732 drives the cam 734 to rotate. The rotation of the cam 734 will produce a periodic pushing effect, and this pushing effect can be used to drive other components to perform reciprocating motions.

[0065] Please refer to again Figure 7 and Figures 9 to 11, the metering medicine delivery part 74 includes a medicine delivery pipe 741. The medicine delivery pipe 741 is connected to the bottom surface of the liquid storage tank 2, and the other end of the medicine delivery pipe 741 is connected to the shunt pipe 71. A hollow box 742 is fixedly connected to the medicine delivery pipe 741. A movable rod 743 is piston - type inserted into the hollow box 742. A sealing block 744 is fixedly sleeved on the movable rod 743, and the sealing block 744 and the hollow box 742 form a sliding structure. One end of the movable rod 743 is fixedly connected to a tension spring 745, and the other end of the tension spring 745 is fixedly connected to the hollow box 742.

[0066] Please refer to again Figure 10 , the metering medicine delivery part 74 further includes a movable groove 746. The movable groove 746 is opened at one end of the movable rod 743. Lock grooves 747 are arranged in an array on the upper and lower inner walls of the movable groove 746. A hollow rod 748 is slidably connected in the movable groove 746. A sliding rod 749 is fixedly connected between the upper and lower inner walls of the hollow rod 748. Two lifting plates 7410 are slidably connected to the sliding rod 749. Lock blocks 7411 and force - receiving blocks 7412 are fixedly connected to the lifting plates 7410, and the force - receiving blocks 7412 penetrate to the outside of the movable rod 743. A reset spring 7413 is fixedly connected between the two lifting plates 7410. One end of the hollow rod 748 is spherical.

[0067] In this embodiment, when the cam 734 rotates to a specific position, it will apply a force to the movable rod 743, causing it to move and stretch the tension spring 745, and the movement of the movable rod 743 drives the sealing block 744 to move together. After the sealing block 744 moves, it will no longer block the medicine delivery pipe 741. At this time, the medicine can flow downward along the medicine delivery pipe 741. Subsequently, the medicine and the water source meet and mix in the mixing part 75. When the cam 734 no longer applies pressure to the movable rod 743, under the restoring force of the tension spring 745, the movable rod 743 will return to its original position. Subsequently, the sealing block 744 blocks the medicine delivery pipe 741 again, preventing the medicine from continuing to flow downward along the medicine delivery pipe 741.

[0068] Considering that in a forest, the moisture content of the soil should be relatively consistent, however, the soil nutrient content around each tree may vary greatly. Therefore, before irrigation, an external soil nutrient rapid detector can be used to pre - detect the soil nutrient status around the trees (for example, when irrigating a certain tree, the soil nutrients around the next tree can be detected simultaneously). Through these detection data, the amount of medicine delivered can be adjusted to achieve the goal of precise fertilization and ensure that each tree can obtain an appropriate amount of nutrients.

[0069] The specific operation is as follows: When in use, press the two force-receiving blocks 7412, so that the two lifting plates 7410 approach each other along the sliding rod 749 and compress the return spring 7413. At this time, the locking block 7411 will disengage from the locking groove 747, allowing the hollow rod 748 to expand and contract along the movable rod 743. After adjusting the required length, release the force-receiving block 7412, and the restoring force of the return spring 7413 will push the two lifting plates 7410 away from each other along the sliding rod 749. Subsequently, the locking block 7411 will snap into the corresponding locking groove 747, making it impossible for the hollow rod 748 to expand and contract along the movable rod 743 any further. When the length of the hollow rod 748 extending along the movable rod 743 is relatively long, the stroke of the cam 734 pushing the movable rod 743 to move increases accordingly, and the stroke of the sealing block 744 moving also increases, resulting in a larger opening of the medicine-dropping tube 741 and a corresponding increase in the amount of medicine dropped. On the contrary, when the length of the hollow rod 748 extending along the movable rod 743 is relatively short, the stroke of the cam 734 pushing the movable rod 743 to move decreases, and the stroke of the sealing block 744 moving also decreases, resulting in a smaller opening of the medicine-dropping tube 741 and a corresponding decrease in the amount of medicine dropped. Generally speaking, when the water output remains unchanged, the longer the length of the hollow rod 748 extending along the movable rod 743, the greater the amount of medicine; the shorter the length, the smaller the amount of medicine. In this way, precise fertilization of the soil can be carried out according to different soil nutrient contents.

[0070] Please refer to again Figure 12 , the mixing part 75 includes a medicine mixing tank 751, the medicine mixing tank 751 is fixedly connected to the shunt pipe 71, and a third rotating shaft 752 is rotatably connected to the medicine mixing tank 751 through a sealing bearing. One end of the third rotating shaft 752 located inside the medicine mixing tank 751 is connected with stirring rods 753 distributed in an array, and the other end of the third rotating shaft 752 is fixedly installed with a fourth linkage gear 754.

[0071] In this embodiment, the second linkage gear 725 and the fourth linkage gear 754 are driven by a toothed belt. This transmission method enables the third rotating shaft 752 to rotate smoothly, thereby driving the stirring rods 753 to rotate. When the medicine flows into the medicine mixing tank 751 together with the water source in the medicine-dropping tube 741 and the shunt pipe 71, the rotating stirring rods 753 fully mix the water source and the medicine. The uniformly mixed liquid fertilizer continues to flow downward along the shunt pipe 71 and finally enters the arc-shaped water storage box 506. Under the action of the arc-shaped water storage box 506, the liquid fertilizer is shunted into a plurality of hollow tubes 601. These hollow tubes 601 are provided with water outlet holes 604, and the liquid fertilizer is directly sprayed into the soil through these water outlet holes 604. This device can directly inject the liquid fertilizer into the root part in the soil, effectively reducing volatilization and thus reducing the waste of the liquid fertilizer.

[0072] In the process of hollow rod 748 inserting into soil, water outlet 604 will be blocked by piston plate 607 and sealing ring 610. Such design can prevent soil particles from entering the inside of hollow tube 601 along water outlet 604, avoiding the problem of poor spraying caused by soil particles blocking hollow tube 601. In the process of spraying liquid fertilizer, water source will enter the inside of hollow tube 601, and under the effect of water source pressure, piston plate 607 will move downward and squeeze compression spring 608. As piston plate 607 moves downward, round rod 609 and sealing ring 610 will also move downward synchronously, and water outlet 604 will open at this time, and liquid fertilizer can be sprayed out smoothly. After liquid fertilizer is sprayed, piston plate 607 is no longer subject to the pressure of water source, and then under the effect of the reset force of compression spring 608, piston plate 607 and sealing ring 610 will reset, thereby blocking water outlet 604 again. In addition, the lifting rod 606 connected to the bottom surface of the piston plate 607 can slide on the ring 605, which not only plays a guiding and limiting role, but also ensures the smoothness of the lifting and lowering process of the piston plate 607, and limits the moving position of the piston plate 607, thereby ensuring the accuracy and reliability of the entire spraying process.

[0073] The working principle of the present invention is:

[0074] Extraction and transmission of water and chemicals:

[0075] The device draws water from an external water tank through a water pump 3 and transports the water to the entire system through a water pipe 4.

[0076] At the same time, the liquid storage tank 2 pre-filled with medicine is connected to the shunt pipe 71 through the medicine delivery pipe 741, ready for the transportation of fertilizer.

[0077] Working mechanism of the driving part 72 and the linkage part 73:

[0078] When the water flows through the driving part 72 , the water flows impact the water wheel 723 to make it rotate, thereby driving the first rotating shaft 722 and the first linkage gear 724 and the second linkage gear 725 thereon to rotate.

[0079] The first linkage gear 724 transmits the transmission to the second rotating shaft 732 in the linkage part 73 through the toothed belt, so that the cam 734 starts to rotate. The periodic movement of the cam 734 is used to push the movable rod 743 of the quantitative drug dispensing part 74 to achieve quantitative drug dispensing.

[0080] Dosing and mixing process:

[0081] The cam 734 periodically pushes the movable rod 743 of the quantitative drug dispensing unit 74 , so that the sealing block 744 moves, opens the drug dispensing tube 741 , and allows the drug to flow into the shunt tube 71 .

[0082] The medicine and the water source meet in the mixing part 75, and are fully mixed by the rotation of the stirring rod 753 to form a uniform liquid fertilizer. The second linkage gear 725 and the fourth linkage gear 754 are driven by a toothed belt, so that the third rotating shaft 752 can rotate smoothly, thereby driving the stirring rod 753 to rotate.

[0083] Precision fertilization and spraying:

[0084] The mixed liquid fertilizer enters the arc-shaped water storage box 506 through the water pipe 4 and is then distributed to a plurality of hollow tubes 601 .

[0085] The design of the arc-shaped water storage box 506 and the support assembly 5 allows the device to adjust its position around the tree to ensure accurate spraying. The support assembly 5 includes a rotating rod 501, a bracket 502, a motor 504, a hydraulic electric push rod 505 and other components.

[0086] The water outlet 604 at the bottom of the hollow tube 601 is opened under the pressure of the piston plate 607, and the liquid fertilizer is directly injected into the soil to meet the needs of the deep root system. When the spraying is completed, the piston plate 607 is reset under the action of the compression spring 608, and the water outlet 604 is resealed to prevent soil particles from clogging the pipe.

[0087] Adjustment mechanism to adapt to different soil conditions:

[0088] According to the data provided by the soil nutrient rapid tester, by adjusting the extension length of the hollow rod 748 in the quantitative medicine dispensing part 74, the stroke of the cam 734 pushing the movable rod 743 is changed, thereby adjusting the amount of fertilizer applied each time to adapt to different soil nutrient conditions and achieve precise fertilization.

[0089] When the hollow rod 748 extends along the movable rod 743 for a long time, the cam 734 pushes the movable rod 743 to move a longer stroke, and the sealing block 744 moves a longer stroke, resulting in a larger opening of the medicine tube 741 and a corresponding increase in the amount of medicine to be released. On the contrary, when the hollow rod 748 extends along the movable rod 743 for a short time, the cam 734 pushes the movable rod 743 to move a shorter stroke, and the sealing block 744 moves a shorter stroke, resulting in a smaller opening of the medicine tube 741 and a corresponding decrease in the amount of medicine to be released.

[0090] In summary, the patented technology realizes a complete process from extraction and mixing of water and chemicals to precise fertilization through a series of mechanical structures (such as water pump 3, water pipe 4, liquid storage tank 2, driving part 72, linkage part 73, quantitative drug delivery part 74, mixing part 75, support assembly 5, hollow tube 601, piston plate 607, sealing ring 610, etc.) and automatic control system, which not only improves the efficiency and accuracy of fertilization, but also reduces resource waste and environmental pollution.

[0091] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention, unless otherwise specified and limited, are implemented according to the conventional means in the art.
