Abstract
Description
Technical Field
[0001] This application relates to the field of cigar tobacco fertilization equipment, and more particularly to a cigar tobacco root fertilization device and a cigar tobacco root fertilization system. Background Technology
[0002] Cigar tobacco requires a variety of nutrients for growth, including macroelements such as nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, as well as microelements such as iron, zinc, manganese, and boron. The nutrient content in the soil is often limited and cannot fully meet the needs of cigar tobacco at different growth stages. Root fertilization can provide cigar tobacco with sufficient and balanced nutrients in a targeted manner.
[0003] In existing technologies, fertilizer is applied to the roots of cigar tobacco using a fertilizer applicator. However, the fertilizer applicator uses a gravity-feed method, which can cause fertilizer segregation during transport, resulting in poor uniformity of nutrient distribution in different soil layers. Summary of the Invention
[0004] The purpose of this application is to at least address the problem of poor nutrient uniformity distribution in different soil layers when fertilizing cigar tobacco roots using existing technologies. This purpose is achieved through the following means:
[0005] The first aspect of this application discloses a root fertilization device for cigar tobacco, comprising a drill head and a feed tube. The drill head is used to break the soil; the feed tube is connected to the drill head, and a feed channel and a plurality of discharge ports are defined inside the feed tube. The feed channel is used to transport fertilizer, and the plurality of discharge ports are spaced apart along the length of the feed tube. Each discharge port penetrates the side wall of the feed tube along the wall thickness direction. One end of each discharge port communicates with the feed channel, and the other end of each discharge port communicates with the outside.
[0006] The cigar tobacco root fertilization device of this application defines a feed channel within the feed cylinder for transporting fertilizer. This ensures a relatively fixed path for the fertilizer during transport, reducing the probability of segregation caused by collisions, friction, and external interference between fertilizer particles. The fertilizer flows as a whole within the channel, avoiding segregation due to differences in the movement speed of different fertilizer particles. Multiple discharge ports are spaced apart along the length of the feed cylinder, allowing fertilizer to be discharged evenly at different locations. The spaced discharge ports also ensure more even distribution of fertilizer in the soil, reducing the probability of localized fertilizer accumulation or excessive concentration, thereby improving the uniformity of nutrient distribution in different soil layers. Furthermore, even if there is a slight tendency for fertilizer segregation within the feed channel, the dispersed discharge through multiple outlets reduces the impact on fertilization uniformity, resulting in a more nearly uniform distribution of fertilizer in the soil and further improving the uniformity of nutrient distribution in different soil layers.
[0007] In some embodiments, the material guiding channel is provided with a plurality of material guiding plates, and the plurality of material guiding plates and the plurality of material outlets are arranged in a one-to-one correspondence. Each material guiding plate is inclined, and the end of each material guiding plate away from the material outlet is located on the side of the end of the material guiding plate near the material outlet away from the drill head, so as to guide the fertilizer to the material outlet.
[0008] In some embodiments, each of the guide plates is provided with a through hole, the through hole being disposed through the guide plate, and the through holes of each two adjacent guide plates are staggered.
[0009] In some embodiments, each of the guide plates is rotatably disposed on the guide cylinder, the guide plate abuts against the inner wall of the guide channel, and the cigar tobacco root fertilization device further includes a first connector, the inner wall of the guide plate and the guide channel are both connected to the first connector, the first connector is configured to restrict the movement of the guide plate, and the first connector is further configured to fail when the weight of the fertilizer on the guide plate is greater than a first preset value.
[0010] In some embodiments, each of the guide plates includes a first guide portion and a second guide portion disposed opposite to each other, the first guide portion and the second guide portion being detachably abutting against each other, the cigar tobacco root fertilization device further includes a second connector, the first guide portion and the second guide portion being connected to the second connector, the second connector being configured to restrict the movement of the first guide portion and the second guide portion, and the second connector being further configured to fail when the weight of the fertilizer on the guide plate is greater than a second preset value.
[0011] In some embodiments, the guide plate further includes a rotating shaft disposed in the guide channel and connected to the guide cylinder, wherein one end of the first guide part and one end of the second guide part are rotatably connected to the rotating shaft and abut against each other in a separable manner.
[0012] In some embodiments, the plurality of discharge ports are at least three discharge ports.
[0013] In some embodiments, the diameter of the discharge port is greater than or equal to 3 centimeters.
[0014] A second aspect of this application discloses a cigar tobacco root fertilization system, comprising: the cigar tobacco root fertilization device as described in the first aspect above, a soil moisture sensor, and a controller. The soil moisture sensor is disposed in the feed cylinder. The controller is electrically connected to the soil moisture sensor.
[0015] The cigar tobacco root fertilization system of this application includes the cigar tobacco root fertilization device as described in the first aspect above. A feed channel is defined within the feed cylinder for transporting fertilizer, ensuring a relatively fixed path for the fertilizer during transport and reducing the probability of segregation due to collisions, friction, and external interference between fertilizer particles. The fertilizer flows as a whole within the channel, avoiding segregation caused by differences in the movement speed of different fertilizer particles. Multiple discharge ports are spaced apart along the length of the feed cylinder, allowing fertilizer to be evenly discharged at different locations. The spaced discharge ports also allow for more even distribution of fertilizer in the soil, reducing the probability of localized fertilizer accumulation or excessive concentration, thereby improving the uniformity of nutrient distribution in different soil layers. Moreover, even if there is a slight tendency for fertilizer segregation within the feed channel, the dispersed discharge through multiple discharge ports reduces the impact on fertilization uniformity, making the fertilizer more evenly distributed in the soil, thus improving the uniformity of nutrient distribution in different soil layers.
[0016] In some embodiments, the cigar tobacco root fertilization system further includes a crushing device comprising a frame, a crushing roller, and crushing blades. The frame defines an installation cavity, an inlet for introducing fertilizer, and a outlet for discharging fertilizer. Both the inlet and the outlet communicate with the installation cavity, and the outlet is connected to the feed channel via a flexible tube. The crushing roller is rotatably mounted on the frame and located within the installation cavity, and is used to crush clumped fertilizer. The crushing blades are rotatably mounted on the frame and located within the installation cavity, and are used to crush clumped fertilizer. Attached Figure Description

[0038] Cigar tobacco requires a variety of nutrients for growth, including macroelements such as nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur, as well as microelements such as iron, zinc, manganese, and boron. The nutrient content in the soil is often limited and cannot fully meet the needs of cigar tobacco at different growth stages. Root fertilization can provide cigar tobacco with sufficient and balanced nutrients in a targeted manner.
[0039] Cigar tobacco has strict requirements for leaf quality. Root fertilization can precisely regulate the nutritional status of the tobacco plant, thereby affecting the chemical composition and physical properties of the leaves and improving their quality. For example, appropriately controlling the amount of nitrogen fertilizer and applying phosphorus, potassium, and micronutrient fertilizers can balance the proportions of sugars, nicotine, and other chemical components in the leaves, resulting in moderate leaf thickness, a loose tissue structure, and increased aroma content, thus enhancing the aroma, taste, and combustibility of cigar tobacco.
[0040] In existing technologies, fertilizer is applied to the roots of cigar tobacco using a fertilizer applicator. However, the fertilizer applicator uses a gravity-feed method, which can cause fertilizer segregation during transport, resulting in poor uniformity of nutrient distribution in different soil layers.
[0041] In order to at least solve the problem of poor uniformity of soil nutrient distribution when fertilizing cigar tobacco roots in existing technologies, embodiments of this application propose a cigar tobacco root fertilization device 110, which can improve the uniformity of soil nutrient distribution when fertilizing cigar tobacco roots.
[0042] Embodiments of this application also propose a cigar tobacco root fertilization system 100 including the cigar tobacco root fertilization device 110 as described above.
[0043] The following describes the cigar tobacco root fertilization device 110 and cigar tobacco root fertilization system 100 of this application with reference to the accompanying drawings.
[0044] in, Figure 1 This is a schematic diagram of a cigar tobacco root fertilization device according to some embodiments of this application; Figure 2 This is a half-sectional view of a cigar tobacco root fertilization device according to some embodiments of this application; Figure 3 for Figure 2Enlarged view of point A in the middle; Figure 4 for Figure 3 A schematic diagram of another state of the middle guide plate; Figure 5 This is a half-sectional view of a cigar tobacco root fertilization device according to other embodiments of this application; Figure 6 for Figure 5 Enlarged view of point B in the middle; Figure 7 This is a schematic diagram of a cigar tobacco root fertilization system according to some embodiments of this application.
[0045] Combination Figure 1 , Figure 2 and Figure 5 As shown, the cigar tobacco root fertilization device 110 of this application embodiment includes a drill head 1 and a feed tube 2. The drill head 1 is used to break the soil; the feed tube 2 is connected to the drill head 1, and a feed channel 21 and a plurality of discharge ports 22 are defined inside the feed tube 2. The feed channel 21 is used to transport fertilizer, and the plurality of discharge ports 22 are spaced apart along the length of the feed tube 2. Each discharge port 22 penetrates the side wall of the feed tube 2 along the wall thickness direction. One end of each discharge port 22 is connected to the feed channel 21, and the other end of each discharge port 22 is connected to the outside.
[0046] The feed cylinder 2 defines a feed channel 21 for transporting fertilizer, ensuring a relatively fixed path for the fertilizer during transport and reducing the probability of segregation caused by collisions, friction, and external interference between fertilizer particles. The fertilizer flows as a whole within the channel, avoiding segregation caused by differences in the movement speed of different fertilizer particles.
[0047] Multiple discharge ports 22 are spaced apart along the length of the feed cylinder 2, allowing fertilizer to be discharged evenly at different locations. The spaced discharge ports 22 allow fertilizer to be distributed more evenly in the soil, reducing the probability of local fertilizer accumulation or excessive concentration, thereby improving the uniformity of nutrient distribution in different soil layers.
[0048] Moreover, even if there is a slight tendency for fertilizer to segregate within the feed channel 21, the dispersed discharge through multiple outlets 22 can reduce the impact on the uniformity of fertilization, making the fertilizer more evenly distributed in the soil, thereby improving the uniformity of nutrient distribution in different soil layers.
[0049] Combination Figure 2 and Figure 4 As shown, in some embodiments, the material guiding channel 21 is provided with multiple material guiding plates 23, and the multiple material guiding plates 23 and multiple discharge ports 22 are arranged in a one-to-one correspondence. Each material guiding plate 23 is inclined, and the end of each material guiding plate 23 away from the discharge port 22 is located on the side of the end of the material guiding plate 23 near the discharge port 22 away from the drill head 1, so as to guide the fertilizer to the discharge port 22.
[0050] Multiple guide plates 23 and multiple discharge ports 22 are set one-to-one, which can accurately guide the fertilizer to the discharge port 22, prevent the fertilizer from flowing randomly in the guide channel 21, reduce the possibility of fertilizer segregation, ensure that each discharge port 22 can discharge stably, and make the fertilizer distributed in the soil in a predetermined position and manner.
[0051] The guide plate 23 is inclined, with the end away from the discharge port 22 being higher and the end closer to the discharge port 22 being lower. This allows the fertilizer to slide naturally down the guide plate 23 using gravity, which helps control the flow speed of the fertilizer and makes the fertilizer flow more evenly and stably to the discharge port 22, thereby achieving uniform fertilization and improving the uniformity of nutrient distribution in different soil layers.
[0052] The inclined guide plate 23 allows the fertilizer to move more smoothly towards the discharge port 22, reducing fertilizer residue and accumulation in the guide channel 21. The fertilizer will not stagnate or clump on the guide plate 23, ensuring the unobstructed flow of the guide channel 21, which helps to improve the efficiency and accuracy of fertilization.
[0053] In some embodiments, each guide plate 23 is provided with a through hole, which is disposed through the guide plate 23, and the through holes of each two adjacent guide plates 23 are staggered.
[0054] The perforated guide plate provides an additional flow channel for the fertilizer. As the guide plate 23 tilts and guides the fertilizer towards the outlet 22, some fertilizer can be conveyed downwards through the perforation, preventing the guide plate 23 from completely blocking the fertilizer's downward movement and allowing the fertilizer to flow continuously and stably within the guide channel 21.
[0055] The through holes of each pair of adjacent guide plates 23 are staggered, so that when the fertilizer passes through the guide plates 23, it will not form a concentrated flow path due to the overlapping positions of the through holes. The staggered through holes can disperse the flow of fertilizer, effectively prevent the fertilizer from accumulating on the guide plates 23, and ensure the smoothness of fertilizer delivery.
[0056] The staggered arrangement of the through holes changes the flow direction and position of the fertilizer as it passes through the guide plate 23, allowing fertilizer from different locations to mix. This further reduces fertilizer segregation, making the fertilizer more uniform during downward transport and improving the uniformity and accuracy of fertilization.
[0057] Combination Figure 5 and Figure 6As shown, in some embodiments, each guide plate 23 is rotatably disposed on the guide cylinder 2, and the guide plate 23 abuts against the inner wall of the guide channel 21. The cigar tobacco root fertilization device 110 also includes a first connector 3, and the inner walls of the guide plate 23 and the guide channel 21 are both connected to the first connector 3. The first connector 3 is configured to restrict the movement of the guide plate 23, and the first connector 3 is also configured to fail when the weight of the fertilizer on the guide plate 23 is greater than a first preset value.
[0058] When the weight of fertilizer on the guide plate 23 exceeds the first preset value, the first connector 3 fails, and the guide plate 23 begins to rotate under the action of the fertilizer, thereby disturbing the fertilizer in the guide channel 21, causing the fertilizer that shows a tendency to segregate to be remixed, thereby improving the uniformity of nutrient distribution in each layer of the soil.
[0059] When too much fertilizer accumulates on the guide plate 23, the large accumulation may lead to excessively high local fertilizer concentrations, increasing the risk of segregation. In this case, the guide plate 23 rotates to adjust the flow direction and flow rate of the fertilizer in a timely manner, dispersing the excess fertilizer to other areas, making the fertilizer distribution within the guide channel 21 more uniform, and reducing the risk of segregation caused by local fertilizer concentration differences.
[0060] When the guide plate 23 rotates, it forms a dynamic mixing zone within the guide channel 21. As the fertilizer passes through this mixing zone, it is agitated by the guide plate 23, resulting in more thorough mixing. This breaks up any agglomeration or stratification that may occur between fertilizer particles, allowing fertilizers of different components to be more evenly distributed throughout the fertilizer flow, effectively reducing the degree of fertilizer segregation.
[0061] As an example, the failure of the first connector 3 may be due to damage to the first connector 3, or it may be due to the first connector 3 being disconnected from at least one of the inner walls of the guide plate 23 and the guide channel 21.
[0062] The first preset value can be determined based on the actual situation. For example, the first preset value is the weight when the fertilizer is piled up too much and there is a risk of segregation.
[0063] Combination Figure 2 , Figure 3 and Figure 4As shown, in some embodiments, each guide plate 23 includes a first guide portion 231 and a second guide portion 232 disposed opposite to each other. The first guide portion 231 and the second guide portion 232 are detachably connected to each other. The cigar tobacco root fertilization device 110 also includes a second connector 4. The first guide portion 231 and the second guide portion 232 are both connected to the second connector 4. The second connector 4 is configured to restrict the movement of the first guide portion 231 and the second guide portion 232. The second connector 4 is also configured to fail when the weight of the fertilizer on the guide plate 23 is greater than a second preset value.
[0064] When excessive fertilizer accumulates on the guide plate 23, the resulting large accumulation may lead to excessively high local fertilizer concentrations, increasing the risk of segregation. In this case, the second connector 4 fails, and the first guide section 231 and the second guide section 232 move, promptly adjusting the fertilizer flow direction and flow rate. This disperses excess fertilizer to other areas, making the fertilizer distribution within the guide channel 21 more uniform and reducing the risk of segregation due to localized fertilizer concentration differences.
[0065] As an example, the failure of the second connector 4 may be due to damage to the second connector 4, or it may be due to the second connector 4 being disconnected from at least one of the inner walls of the guide plate 23 and the guide channel 21.
[0066] The second preset value can be determined based on the actual situation. For example, the second preset value is the weight when the fertilizer is piled up too much and there is a risk of segregation.
[0067] Combination Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the guide plate 23 further includes a rotating shaft 233 disposed in the guide channel 21 and connected to the guide cylinder 2. One end of the first guide part 231 and one end of the second guide part 232 are rotatably connected to the rotating shaft 233 and abut against each other in a separable manner.
[0068] The first guide section 231 and the second guide section 232 are connected to the guide cylinder 2 via a rotating shaft 233 and can rotate. After the second connector 4 fails, the first guide section 231 and the second guide section 232 rotate, which can provide guidance for excess fertilizer and disperse it to other areas, making the distribution of fertilizer in the guide channel 21 more uniform and reducing the risk of segregation caused by local fertilizer concentration differences.
[0069] like Figure 1 As shown, in some embodiments, the plurality of discharge ports 22 are at least three discharge ports 22.
[0070] At least three discharge ports 22 allow fertilizer to be discharged from multiple different locations, thus providing broader coverage of the cigar tobacco root system. Each discharge port 22 applies fertilizer within a certain range, ensuring a more even distribution of fertilizer in the soil and preventing localized over- or under-fertilization. This promotes uniform nutrient absorption by the cigar tobacco roots, fosters balanced overall plant growth, and improves the uniformity of nutrient distribution across soil layers.
[0071] In some embodiments, the diameter of the discharge port 22 is greater than or equal to 3 cm.
[0072] The diameter of the discharge port 22 is greater than or equal to 3 cm, which can reduce the probability of the discharge port 22 clogging the fertilizer and allow the fertilizer to be discharged smoothly from the discharge port 22.
[0073] like Figure 7 As shown, the cigar tobacco root fertilization system 100 of this application embodiment includes: the cigar tobacco root fertilization device 110 as described in the above embodiment, a soil moisture sensor, and a controller 120. The soil moisture sensor is located in the feed cylinder 2. The controller 120 is electrically connected to the soil moisture sensor. Soil moisture information is acquired in real time through the soil moisture sensor, and the controller 120 can determine the drilling depth based on the soil moisture information.
[0074] The cigar tobacco root fertilization system 100 of this application embodiment includes: a cigar tobacco root fertilization device 110 as described in the above embodiment, wherein a feed channel 21 is defined within the feed cylinder 2 for transporting fertilizer, so that the fertilizer has a relatively fixed path during transportation, reducing the probability of separation of fertilizer particles due to mutual collision, friction, and interference from external factors. The fertilizer flows as a whole within the channel, avoiding separation caused by differences in the movement speed of different fertilizer particles. Multiple discharge ports 22 are spaced apart along the length of the feed cylinder 2, so that the fertilizer can be evenly discharged at different positions. The spaced discharge ports 22 allow the fertilizer to be more evenly distributed in the soil, reducing the probability of local fertilizer accumulation or excessive concentration, thereby improving the uniformity of nutrient distribution in different soil layers. Moreover, even if there is a slight tendency for fertilizer to separate within the feed channel 21, the dispersed discharge through multiple discharge ports 22 can reduce the impact on the uniformity of fertilization, making the fertilizer more evenly distributed in the soil, thereby improving the uniformity of nutrient distribution in different soil layers.
[0075] In some embodiments, the cigar tobacco root fertilization system 100 further includes a crushing device 130, which includes a frame, a crushing roller, and crushing blades. The frame defines an installation cavity, an inlet for introducing fertilizer, and a outlet for discharging fertilizer. Both the inlet and outlet are connected to the installation cavity, and the outlet is connected to a guide channel 21 via a flexible pipe. The crushing roller is rotatably mounted on the frame and located within the installation cavity, and is used to crush clumped fertilizer. The crushing blades are rotatably mounted on the frame and located within the installation cavity, and are used to crush clumped fertilizer.
[0076] During storage and transportation, fertilizers are prone to clumping due to moisture and compression. Crushing rollers and blades can effectively break up clumped fertilizer. Through the crushing of the rollers and the cutting of the blades, large clumps of fertilizer are pulverized into appropriately sized particles. This ensures that the fertilizer particles are relatively uniform in size when transported through the feeding channel to the roots of cigar tobacco, preventing localized excessively high or low fertilizer concentrations caused by clumping. This guarantees uniform fertilization and promotes even nutrient absorption by the cigar tobacco roots.
[0077] After the crushing device 130 crushes the lumpy fertilizer, it allows the fertilizer to smoothly pass through the flexible tube into the feed channel 21 and be discharged from the outlet 22, thereby reducing the risk of clogging the outlet 22 and ensuring the continuity and stability of the fertilization process. In addition, the crushing device 130 can maintain the fertilizer at a suitable particle size, so that the flow characteristics of the fertilizer in the feed channel remain stable.
[0078] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
