[0036] During the cultivation process of cigars, multiple fertilization procedures are required, including opening trenches on the leveled land 20 - 30 days before transplanting and evenly spreading the base fertilizer at the bottom of the trenches. About 7 days after transplanting the tobacco seedlings, potassium nitrate and pest control agents need to be irrigated to the roots. 45 - 50 days after transplanting, the fertilizer also needs to be evenly sprayed on both the front and back sides of the tobacco leaves.

[0037] However, in the prior art, it is not possible to fertilize both the front and back sides of the tobacco leaves simultaneously, resulting in low efficiency of tobacco leaf fertilization.

[0038] In order to at least solve the problem of low efficiency in fertilizing tobacco leaves, an embodiment of the present application provides a cigar tobacco fertilizer applicator 100, which can fertilize both the front and back sides of cigar tobacco leaves simultaneously, thereby improving the fertilization efficiency of cigar tobacco leaves.

[0039] The cigar tobacco fertilizer applicator 100 according to the embodiment of the present application will be described below with reference to the accompanying drawings.

[0040] As Figure 1 shown, the cigar tobacco fertilizer applicator 100 according to the embodiment of the present application includes a frame 1, a driving mechanism 2, and a spraying mechanism 3. A fertilizer storage bin 111 is defined inside the frame 1, and the fertilizer storage bin 111 is used for storing fertilizers; the driving mechanism 2 is arranged on the frame 1 and is used to drive the frame 1 to move; the spraying mechanism 3 includes a first spraying device 31 and a second spraying device 32. In a first direction a, the first spraying device 31 and the second spraying device 32 are movably arranged on the frame 1 and are communicated with the fertilizer storage bin 111. The first spraying device 31 and the second spraying device 32 are spaced apart in the first direction a. A first spraying port 3111 of the first spraying device 31 and a second spraying port 3211 of the second spraying device 32 are arranged facing each other in the first direction a. The first spraying port 3111 and the second spraying port 3211 are used for spraying fertilizers on both sides of the cigar tobacco leaves; wherein, the first direction a is the height direction of the frame 1.

[0041] When preparing to fertilize the leaves of cigar tobacco, adjust the positions of the first spraying device 31 and the second spraying device 32 in the first direction a, so that the first spraying device 31 and the second spraying device 32 are located on the front and back sides of the cigar tobacco leaves. Since the first spraying port 3111 of the first spraying device 31 and the second spraying port 3211 of the second spraying device 32 are arranged facing each other in the first direction a, therefore, the first spraying device 31 and the second spraying device 32 can fertilize the cigar tobacco leaves from both sides. Make the first spraying device 31 and the second spraying device 32 both in suitable positions for spraying fertilizers on the cigar tobacco leaves, thereby avoiding damage to the cigar tobacco leaves caused by the first spraying device 31 and the second spraying device 32 being too close to the cigar tobacco leaves, and avoiding a decline in fertilization effect caused by the first spraying device 31 and the second spraying device 32 being too far from the cigar tobacco leaves.

[0042] When fertilizing the leaves of cigar tobacco, make the fertilizer storage bin 111 convey the stored fertilizers to the first spraying device 31 and the second spraying device 32, so that the first spraying device 31 and the second spraying device 32 fertilize the front and back sides of the cigar tobacco leaves.

[0043] The cigar tobacco fertilizer applicator 100 according to the embodiment of the present application is provided with a first spraying device 31 and a second spraying device 32 spaced apart in the first direction a, and the first spraying port 3111 of the first spraying device 31 and the second spraying port 3211 of the second spraying device 32 are arranged facing each other in the first direction a, so that the first spraying device 31 and the second spraying device 32 can spray fertilizers onto the front and back sides of the cigar tobacco leaves, thereby being able to fertilize the front and back sides of the cigar tobacco leaves, and further improving the fertilization efficiency of the cigar tobacco leaves.

[0044] In some specific embodiments, both the first spraying device 31 and the second spraying device 32 are connected to the fertilizer storage bin 111 through a first pump body. The first pump body is used to pump the fertilizer in the fertilizer storage bin 111 into the first spraying device 31 and the second spraying device 32, so that the fertilizers can be sprayed through the first spraying device 31 and the second spraying device 32.

[0045] The first pump body generates a pressure difference to drive the fertilizer to flow out of the fertilizer storage bin 111 and enter the first spraying device 31 and the second spraying device 32, so as to ensure the fertilizer supply of the first spraying device 31 and the second spraying device 32, and thus ensure the normal progress of the fertilization operation.

[0046] The first pump body can transport the fertilizer to the first spraying device 31 and the second spraying device 32 with relatively stable pressure and flow rate, so as to make the fertilizer amounts and spraying pressures ejected by the first spraying device 31 and the second spraying device 32 consistent, so that the fertilizers can be evenly sprayed on both sides of the cigar tobacco leaves, and further promote the balanced growth of the tobacco leaves and improve the quality and yield of the tobacco leaves.

[0047] In the prior art, when the fertilizer droplets sprayed onto the lower surface (the bottom of the cigar tobacco leaves) are too large, under the action of gravity, the fertilizer droplets are likely to separate from the lower surface of the cigar tobacco leaves, thus affecting the fertilization effect on the cigar tobacco leaves.

[0048] For this reason, as Figure 3 shown, in some embodiments, the first spraying device 31 includes a first nozzle 311. The first nozzle 311 defines a first fertilizer inlet channel 3112 for introducing fertilizer, a first air inlet channel 3113 for introducing positive-pressure air, and a first spraying port 3111 for spraying fertilizer onto the bottom of the cigar tobacco leaves. The first fertilizer inlet channel 3112 and the first air inlet channel 3113 are arranged opposite to each other in the second direction b and communicate with each other. The first air inlet channel 3113 is configured to form atomized droplets by impacting the fertilizer with positive-pressure air. The first air inlet channel 3113 is also configured to dissolve part of the air in the fertilizer by impacting the fertilizer with positive-pressure air. Both the first fertilizer inlet channel 3112 and the first air inlet channel 3113 are communicated with the first spraying port 3111, wherein the second direction b is perpendicular to the first direction a.

[0049] The first fertilizer inlet channel 3112 and the first air inlet channel 3113 are oppositely arranged in the second direction b and communicate with each other. When the positive-pressure air enters from the first air inlet channel 3113 and the fertilizer flows in from the first fertilizer inlet channel 3112, the positive-pressure air will impact the fertilizer at high speed, and the high-speed air flow interacts with the fertilizer, thereby tearing the fertilizer liquid into fine droplets, and further reducing the size of the fertilizer droplets ejected from the first ejection port 3111, so that the fertilizer droplets ejected from the first ejection port 3111 can stably adhere to the lower surface of the cigar tobacco leaf.

[0050] Moreover, the small-sized fertilizer droplets have a larger specific surface area. When the fertilizer droplets adhere to the bottom of the cigar tobacco leaf, there can be a larger contact area between the droplets and the leaf surface, so that the nutrients in the fertilizer can enter the tobacco leaf interior more quickly and fully through the stomata, cuticle and other parts of the tobacco leaf, thereby significantly improving the absorption efficiency of the tobacco leaf for the fertilizer.

[0051] In addition, by dissolving an appropriate amount of air in the fertilizer, the carbon dioxide in the air dissolved in the fertilizer can provide raw materials for the photosynthesis of the tobacco leaf, thereby being able to increase the growth rate of the tobacco leaf.

[0052] In the prior art, when the fertilizer droplets sprayed on the upper surface (the top of the cigar tobacco leaf) are too large, under the action of gravity, the fertilizer droplets easily slide off the upper surface of the cigar tobacco leaf, thus affecting the fertilization effect on the cigar tobacco leaf.

[0053] For this reason, as Figure 4 shown, in some embodiments, the second spraying device 32 includes a second nozzle 321. The second nozzle 321 defines a second fertilizer inlet channel 3212 for introducing fertilizer, a second air inlet channel 3213 for introducing positive-pressure air, and a second ejection port 3211 for spraying fertilizer onto the top of the cigar tobacco leaf. The second fertilizer inlet channel 3212 and the second air inlet channel 3213 are oppositely arranged in the second direction b and communicate with each other. The second air inlet channel 3213 is configured to impact the fertilizer with positive-pressure air to form atomized droplets, and the second air inlet channel 3213 is further configured to impact the fertilizer with positive-pressure air to dissolve part of the air in the fertilizer. Both the second fertilizer inlet channel 3212 and the second air inlet channel 3213 communicate with the second ejection port 3211.

[0054] The second fertilizer inlet channel 3212 and the second air inlet channel 3213 are oppositely arranged in the second direction b and communicate with each other. When the positive-pressure air enters from the second air inlet channel 3213 and the fertilizer flows in from the second fertilizer inlet channel 3212, the positive-pressure air will impact the fertilizer at high speed, and the high-speed air flow interacts with the fertilizer, thereby tearing the fertilizer liquid into fine droplets, and further reducing the size of the fertilizer droplets ejected from the second ejection port 3211, so that the fertilizer droplets ejected from the second ejection port 3211 can stably adhere to the upper surface of the cigar tobacco leaf.

[0055] Moreover, small-sized fertilizer droplets have a larger specific surface area. When the fertilizer droplets adhere to the top of the cigar tobacco leaves, there is a larger contact area between the droplets and the leaf surface, enabling the nutrients in the fertilizer to enter the tobacco leaves more quickly and fully through the stomata, cuticle, and other parts of the leaves, thus significantly improving the absorption efficiency of the tobacco leaves for the fertilizer.

[0056] In addition, by dissolving an appropriate amount of air in the fertilizer, the carbon dioxide in the air dissolved in the fertilizer can provide raw materials for the photosynthesis of the tobacco leaves, thereby improving the growth rate of the tobacco leaves.

[0057] In some alternative embodiments, both the first air intake channel 3113 and the second air intake channel 3213 are in communication with the second pump body, and the second pump body is configured to pump positive-pressure gas into the first air intake channel 3113 and the second air intake channel 3213.

[0058] The second pump body can provide a stable source of positive-pressure gas to the first nozzle 311 and the second nozzle 321, enabling the first nozzle 311 and the second nozzle 321 to operate stably.

[0059] As Figure 1 shown, in some embodiments, the first spraying device 31 further includes a first fixing plate 312, multiple first nozzles 311 are provided, and each first nozzle 311 is mounted on the first fixing plate 312. The second spraying device 32 further includes a second fixing plate 322, multiple second nozzles 321 are provided, and each second nozzle 321 is mounted on the second fixing plate 322.

[0060] Mounting multiple first nozzles 311 on the first fixing plate 312 and multiple second nozzles 321 on the second fixing plate 322, and the simultaneous operation of the multiple first nozzles 311 and second nozzles 321 can increase the spraying coverage area of the fertilizer. When fertilizing the cigar tobacco leaves, the multiple first nozzles 311 and second nozzles 321 can cover a larger area of the tobacco leaves at one time, reducing the time required for fertilization and the number of times of moving the equipment back and forth, thereby improving the overall fertilization efficiency.

[0061] The first fixing plate 312 can provide a stable mounting platform for the first nozzle 311, and the second fixing plate 322 can provide a stable mounting platform for the second nozzle 321, thereby improving the stability of the first nozzle 311 and the second nozzle 321, and thus improving the spraying accuracy of the first nozzle 311 and the second nozzle 321.

[0062] In addition, the integration of the first nozzle 311 into the first fixing plate 312 can make the structure of the first spraying device 31 more compact and reasonable. The integration of the second nozzle 321 into the second fixing plate 322 can make the structure of the second spraying device 32 more compact and reasonable.

[0063] As Figure 1 shown, in some embodiments, the rack 1 includes a mounting rod 12 and a frame body 11 that defines a fertilizer storage bin 111. The mounting rod 12 is mounted on the frame body 11 and extends along a first direction a. The first spraying device 31 further includes a first slider 313, which is connected to the first fixed disk 312. The first slider 313 is slidably connected to the mounting rod 12 along the first direction a. The first spraying device 31 further includes a second slider 323, which is connected to the second fixed disk 322. The second slider 323 is slidably connected to the mounting rod 12 along the first direction a. The first slider 313 and the second slider 323 are spaced apart.

[0064] The mounting rod 12 extends along the first direction a. The first slider 313 and the second slider 323 can slide on the mounting rod 12 along the first direction a, enabling the first spraying device 31 and the second spraying device 32 to adjust their positions in the first direction a according to the actual needs of cigar tobacco leaves, so that the first spraying device 31 and the second spraying device 32 can spray fertilizers on tobacco leaves at different heights.

[0065] The first slider 313 and the second slider 323 are spaced apart. By adjusting the distance between the first slider 313 and the second slider 323, the relative positions of the first spraying device 31 and the second spraying device 32 can be changed, thereby enabling the coverage range of the fertilizer to be adjusted. For example, when fertilizing a wider area is required, the distance between the first slider 313 and the second slider 323 is increased; when fertilizing a narrower area is required, the distance between the first slider 313 and the second slider 323 is decreased. Thus, the fertilizer can be evenly covered on the tobacco leaves, avoiding the occurrence of fertilization blind spots or excessive local fertilization.

[0066] In some alternative embodiments, the first slider 313 is provided with a first locking rod, which is threadedly connected to the first slider 313 in a movable manner between a first locking position and a first unlocking position. The first locking rod in the first locking position abuts against the mounting rod 12 to restrict the movement of the first slider 313 relative to the mounting rod 12, and the first locking rod in the first unlocking position is separated from the mounting rod 12.

[0067] The first locking rod is threadedly connected to the first slider 313, which is simple and convenient to operate.

[0068] After the first slider 313 slides to a suitable position, by screwing the first locking rod to the first locking position, the first locking rod abuts against the mounting rod 12, which can fix the position of the first slider 313, reducing the probability of displacement of the first spraying device 31 during fertilization due to external forces or its own vibration, etc., thereby improving the stability of the first spraying device 31 when spraying fertilizers.

[0069] When it is necessary to readjust the position of the first spraying device 31, the first locking rod is screwed to the first unlocking position, and the first slider 313 can slide freely on the mounting rod 12. After adjusting to the new position, screwing the first locking rod to the locking position again can complete the positioning. The whole process is fast and convenient, and can meet the requirements for quickly adjusting the position of the first spraying device 31 in different fertilization scenarios.

[0070] In some alternative embodiments, the second slider 323 is provided with a second locking rod, and the second locking rod is threadedly connected to the second slider 323 in a movable manner between the first locking position and the first unlocking position. The second locking rod located at the first locking position abuts against the mounting rod 12 to restrict the movement of the second slider 323 relative to the mounting rod 12, and the second locking rod located at the first unlocking position is separated from the mounting rod 12.

[0071] The second locking rod is threadedly connected to the second slider 323, and the operation is simple and convenient.

[0072] When the second slider 323 slides to a suitable position, by screwing the second locking rod to the first locking position to make the second locking rod abut against the mounting rod 12, the position of the second slider 323 can be fixed, reducing the probability of displacement of the first spraying device 31 during fertilization due to external forces or its own vibration, etc., thereby improving the stability of the first spraying device 31 when spraying fertilizer.

[0073] When it is necessary to readjust the position of the first spraying device 31, the second locking rod is screwed to the first unlocking position, and the second slider 323 can slide freely on the mounting rod 12. After adjusting to the new position, screwing the second locking rod to the locking position again can complete the positioning. The whole process is fast and convenient, and can meet the requirements for quickly adjusting the position of the first spraying device 31 in different fertilization scenarios.

[0074] Combined Figure 1 and Figure 2 As shown in the figure, in some embodiments, there are multiple spraying mechanisms 3, and the multiple spraying mechanisms 3 are arranged at intervals in the third direction c, and the third direction c, the second direction b, and the first direction a are perpendicular to each other in pairs.

[0075] As some examples, the third direction c is the width direction of the frame 1.

[0076] The multiple spraying mechanisms arranged at intervals can form a large coverage range in the third direction c, so as to be able to fertilize the cigar tobacco leaves in a relatively wide area at the same time, thereby significantly improving the fertilization efficiency and reducing the fertilization time.

[0077] In the prior art, multiple fertilization processes are required during the cultivation of cigar tobacco. Specifically, about 20 - 30 days before transplanting, trenches need to be dug on the leveled land, and the base fertilizer is evenly spread at the bottom of the trenches. Approximately 7 days after transplanting the tobacco seedlings, potassium nitrate and pest control agents need to be applied to the roots by irrigation. 45 - 50 days after transplanting, the fertilizer also needs to be evenly sprayed on both the front and back sides of the tobacco leaves. That is to say, cigar tobacco requires multiple fertilizations during its growth process. Fertilization is needed for the roots of the cigar in the early stage, and spraying is required for the tobacco leaves of the cigar in the later stage.

[0078] However, in the prior art, there is no device for fertilizing cigar tobacco throughout its growth process. During the fertilization process, the fertilization device must be replaced. Therefore, multiple fertilization devices need to be prepared when cultivating cigar tobacco, which greatly increases the cultivation cost and reduces the work efficiency.

[0079] For this reason, as Figure 1 shown, in some embodiments, the cigar tobacco fertilizer applicator 100 further includes a fertilizer application cylinder 4. The fertilizer application cylinder 4 is installed on the frame 1, and the fertilizer application cylinder 4 is connected to the fertilizer storage bin 111 in a switchable manner and is used for fertilizing the roots of cigar tobacco.

[0080] By setting the fertilizer application cylinder 4, the roots of cigar tobacco can be fertilized, and by setting the spraying mechanism 3, both the front and back sides of the cigar tobacco leaves can be fertilized. Thus, the fertilizer applicator can be used for fertilizing cigar tobacco throughout its growth process, reducing the cultivation cost of cigar tobacco and improving the work efficiency.

[0081] As Figure 1 shown, in some embodiments, the fertilizer storage bin 111 is provided with a fertilizer outlet 112 communicating with the fertilizer application cylinder 4. A partition plate 113 is provided in the fertilizer storage bin 111. The partition plate 113 is movably arranged at the fertilizer outlet 112 to be able to close or open the fertilizer outlet 112.

[0082] When fertilization is not required, the partition plate 113 can close the fertilizer outlet 112, effectively preventing the leakage of the fertilizer in the fertilizer storage bin 111.

[0083] By controlling the size and time for the partition plate 113 to open the fertilizer outlet 112, the amount of fertilizer entering the fertilizer application cylinder 4 from the fertilizer storage bin 111 can be precisely controlled. This helps to accurately adjust the fertilization amount according to factors such as different growth stages of cigar tobacco leaves, soil fertility conditions, and planting density, avoiding fertilizer waste or insufficient fertilization, ensuring that the nutrient supply required for the growth of cigar tobacco leaves is just right, and thus improving the quality and yield of the tobacco leaves.

[0084] During the movement of the partition plate 113, the fertilizer at the fertilizer outlet 112 can be stirred and dredged to a certain extent, preventing the fertilizer from accumulating or caking near the fertilizer outlet, and thus avoiding affecting normal fertilization due to the blockage of the fertilizer outlet 112.

[0085] As Figure 1 shown, in some embodiments, the cigar tobacco fertilizer applicator 100 further includes a furrow opener 5 for breaking up the soil.

[0086] The furrow opener 5 breaks up the soil to form a groove in the soil so that the fertilizer can be accurately applied to a depth suitable for the roots of the cigar tobacco to absorb.

[0087] As Figure 1 shown, in some embodiments, the drive mechanism 2 includes a runner 21 and a drive motor 22. The runner 21 is rotatably arranged on the frame 1, and the drive motor 22 is arranged on the frame 1 and is in transmission connection with the runner 21.

[0088] The drive motor 22 serves as a power source and can continuously and stably output power. Through the transmission connection with the runner 21, it drives the runner 21 to rotate, thereby being able to drive the cigar tobacco fertilizer applicator 100 of the embodiment of the present application to move.

[0089] The structures of the runner 21 and the drive motor 22 are relatively simple and have fewer components, reducing the failure rate of the equipment. At the same time, because the structures of the runner 21 and the drive motor 22 are simple, the maintenance and repair of the runner 21 and the drive motor 22 are also relatively convenient. When the drive mechanism 2 fails, the operator can relatively easily find the fault point and repair it, thereby reducing the downtime of the cigar tobacco fertilizer applicator 100 of the embodiment of the present application, and further improving the use efficiency of the cigar tobacco fertilizer applicator 100 of the embodiment of the present application.

[0090] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed in the present application should be covered by the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
