Description

Technical Field

[0001] This application relates to the field of cigar tobacco fertilization equipment, and particularly to a device for fertilizing the roots of cigar tobacco and a system for fertilizing the roots of cigar tobacco. Background Art

[0002] The growth of cigar tobacco requires various nutrients, such as macronutrients like nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, and micronutrients like iron, zinc, manganese, boron, etc. The nutrient content in the soil is often limited and cannot fully meet the needs of cigar tobacco at different growth stages. By fertilizing the roots, sufficient and balanced nutrients can be provided to cigar tobacco in a targeted manner.

[0003] In the prior art, a fertilizing machine is used to fertilize the roots of cigar tobacco. However, the fertilizing machine uses the gravity feeding method for fertilization, and segregation is likely to occur during the transportation of fertilizers, resulting in poor uniformity of nutrient distribution in each layer of the soil. Summary of the Invention

[0004] The purpose of this application is to at least solve the problem of poor uniformity of nutrient distribution in each layer of the soil when fertilizing the roots of cigar tobacco in the prior art. This purpose is achieved in the following ways: A first aspect of this application provides a device for fertilizing the roots of cigar tobacco, including a drilling head and a material guiding cylinder. The drilling head is used to break the soil; the material guiding cylinder is connected to the drilling head, and a material guiding channel and a plurality of discharge ports are defined in the material guiding cylinder. The material guiding channel is used to transport fertilizers, and the plurality of discharge ports are spaced at intervals in the length direction of the material guiding cylinder. Each discharge port penetrates the side wall of the material guiding cylinder in the wall thickness direction of the material guiding cylinder. One end of each discharge port is communicated with the material guiding channel, and the other end of each discharge port is communicated with the outside.

[0005] In the device for fertilizing the roots of cigar tobacco of this application, a material guiding channel for transporting fertilizers is defined in the material guiding cylinder, so that the fertilizers have a relatively fixed path during transportation, reducing the probability of segregation caused by mutual collision, friction between fertilizer particles and interference from external factors. The fertilizers flow as a whole in the channel, avoiding the segregation phenomenon caused by the difference in the movement speed of different fertilizer particles. The plurality of discharge ports are spaced at intervals in the length direction of the material guiding cylinder, enabling the fertilizers to be evenly discharged at different positions. The spaced discharge ports can make the fertilizers more evenly distributed in the soil, reducing the probability of local fertilizer accumulation or excessive concentration, thereby improving the uniformity of nutrient distribution in each layer of the soil. Moreover, even if there is a slight segregation tendency of the fertilizers in the material guiding channel, through the dispersed discharge of the plurality of discharge ports, the impact on the fertilization uniformity can be reduced, making the fertilizers more evenly distributed in the soil, thereby improving the uniformity of nutrient distribution in each layer of the soil.

A plurality of discharge ports are arranged at intervals in the length direction of the material guiding cylinder, enabling the fertilizers to be evenly discharged at different positions. The discharge ports arranged at intervals can make the fertilizers more evenly distributed in the soil, reducing the probability of local fertilizer accumulation or excessive concentration, thereby improving the uniformity of nutrient distribution in each layer of the soil. Moreover, even if there is a slight segregation tendency of the fertilizers in the material guiding channel, through the dispersed discharge of the plurality of discharge ports, the influence on the fertilization uniformity can be reduced, making the fertilizers closer to uniform distribution in the soil, thereby improving the uniformity of nutrient distribution in each layer of the soil.

[0024] The growth of cigar tobacco requires various nutrients, such as macronutrients like nitrogen, phosphorus, potassium, calcium, magnesium, sulfur, and micronutrients like iron, zinc, manganese, boron, etc. The nutrient content in the soil is often limited and cannot fully meet the needs of cigar tobacco at different growth stages. Through root fertilization, sufficient and balanced nutrients can be provided for cigar tobacco in a targeted manner.

[0025] Cigar tobacco has strict requirements for the quality of tobacco leaves. Through root fertilization, the nutritional status of tobacco plants can be precisely regulated, thereby affecting the chemical composition and physical properties of tobacco leaves and improving the quality of tobacco leaves. For example, by appropriately controlling the dosage of nitrogen fertilizer and applying phosphorus, potassium fertilizers, and micronutrient fertilizers in combination, the proportion of chemical components such as sugar and nicotine in tobacco leaves can be coordinated, the leaf thickness can be moderate, the tissue structure can be loose, and the content of aroma substances can increase, thereby improving the quality indicators such as aroma, taste, and combustibility of cigar tobacco leaves.

[0026] In the prior art, a fertilizer applicator is used to apply fertilizer to the roots of cigar tobacco. However, the fertilizer applicator uses the gravity feeding method for fertilization, and segregation is likely to occur during the transportation of fertilizer, resulting in poor uniformity of nutrient distribution in each layer of the soil.

[0027] In order to at least solve the problem of poor uniformity of nutrient distribution in each layer of the soil when applying fertilizer to the roots of cigar tobacco in the prior art, an embodiment of this application proposes a cigar tobacco root fertilization device 110, which can improve the uniformity of nutrient distribution in each layer of the soil when applying fertilizer to the roots of cigar tobacco.

[0028] An embodiment of this application also proposes a cigar tobacco root fertilization system 100 including the cigar tobacco root fertilization device 110 as described in the above embodiment.

[0029] The following introduces the cigar tobacco root fertilization device 110 and the cigar tobacco root fertilization system 100 according to the embodiments of this application with reference to the drawings.

[0030] Among them, Figure 1 is a schematic diagram of a cigar tobacco root fertilization device according to some embodiments of this application; Figure 2 is a half-sectional view of a cigar tobacco root fertilization device according to some embodiments of this application; Figure 3 is Figure 2Enlarged view of area A in [the figure]; Figure 4 is Figure 3 Schematic diagram of another state of the material guiding plate in [the figure]; Figure 5 Half-sectional view of the cigar tobacco root fertilization device according to some other embodiments of the present application; Figure 6 is Figure 5 Enlarged view of area B in [the figure]; Figure 7 Schematic diagram of the cigar tobacco root fertilization system according to some embodiments of the present application.

[0031] Combined with Figure 1 、 Figure 2 and Figure 5 As shown, the cigar tobacco root fertilization device 110 according to the embodiments of the present application includes a drill head 1 and a material guiding cylinder 2. The drill head 1 is used to break through the soil; the material guiding cylinder 2 is connected to the drill head 1. A material guiding channel 21 and a plurality of discharge ports 22 are defined in the material guiding cylinder 2. The material guiding channel 21 is used to transport fertilizers, and the plurality of discharge ports 22 are spaced apart in the length direction of the material guiding cylinder 2. Each discharge port 22 penetrates the side wall of the material guiding cylinder 2 in the wall thickness direction of the material guiding cylinder 2. One end of each discharge port 22 is communicated with the material guiding channel 21, and the other end of each discharge port 22 is communicated with the outside.

[0032] A material guiding channel 21 for transporting fertilizers is defined in the material guiding cylinder 2, so that the fertilizers have a relatively fixed path during transportation, reducing the probability of segregation caused by mutual collision, friction between fertilizer particles and interference by external factors. The fertilizers flow as a whole in the channel, avoiding the segregation phenomenon caused by the difference in the movement speed of different fertilizer particles.

[0033] The plurality of discharge ports 22 are spaced apart in the length direction of the material guiding cylinder 2, so that the fertilizers can be discharged evenly at different positions. The spaced-apart discharge ports 22 can make the fertilizers more evenly distributed in the soil, reducing the probability of local fertilizer accumulation or excessive concentration, thereby improving the uniformity of nutrient distribution in each layer of the soil.

[0034] Moreover, even if there is a slight segregation tendency of the fertilizers in the material guiding channel 21, through the dispersed discharge of the plurality of discharge ports 22, the influence on the fertilization uniformity can be reduced, making the fertilizers closer to uniform distribution in the soil, thereby improving the uniformity of nutrient distribution in each layer of the soil.

[0035] Combined with Figure 2 and Figure 4 As shown, in some embodiments, a plurality of material guiding plates 23 are provided in the material guiding channel 21. The plurality of material guiding plates 23 are arranged in one-to-one correspondence with the plurality of discharge ports 22. Each material guiding plate 23 is inclined. One end of each material guiding plate 23 facing away from the discharge port 22 is located on the side of the end of the material guiding plate 23 close to the discharge port 22 facing away from the drill head 1, so as to guide the fertilizers to the discharge port 22.

[0036] Multiple guide plates 23 and multiple discharge ports 22 are arranged in a one-to-one correspondence, which can accurately guide the fertilizer to the discharge port 22, prevent the fertilizer from flowing freely in the guide channel 21, reduce the possibility of fertilizer segregation, and ensure that each discharge port 22 can discharge the fertilizer stably, so that the fertilizer is distributed in the soil according to the predetermined position and method.

[0037] The guide plate 23 is tilted, with the end away from the discharge port 22 being higher and the end close to the discharge port 22 being lower. The fertilizer can slide down naturally on the guide plate 23 by utilizing gravity, which helps to control the flow rate of the fertilizer and make the fertilizer flow to the discharge port 22 more evenly and stably, thereby achieving uniform fertilization and improving the uniformity of nutrient distribution in each layer of the soil.

[0038] The inclined guide plate 23 enables the fertilizer to move more smoothly toward the discharge port 22, reducing the residue and accumulation of fertilizer in the guide channel 21. The fertilizer will not stagnate or agglomerate on the guide plate 23, ensuring the smooth flow of the guide channel 21, which is conducive to improving the efficiency and accuracy of fertilization.

[0039] In some embodiments, each material guide plate 23 is provided with a through hole, and the through hole is arranged through the material guide plate 23, and the through holes of every two adjacent material guide plates 23 are arranged in a staggered manner.

[0040] The holes passing through the guide plate provide an additional flow channel for the fertilizer. When the guide plate 23 tilts to guide the fertilizer to flow toward the discharge port 22, part of the fertilizer can be transported downward through the holes, thereby preventing the guide plate 23 from completely blocking the fertilizer from moving downward, and allowing the fertilizer to flow continuously and stably in the guide channel 21.

[0041] The through holes of each two adjacent guide plates 23 are staggered so that when the fertilizer passes through the guide plates 23, a concentrated flow path will not be formed due to the overlap of the through holes. The staggered through holes enable the fertilizer to disperse the flow of the fertilizer, effectively preventing the fertilizer from accumulating on the guide plates 23, thereby ensuring smooth transportation of the fertilizer.

[0042] The staggered through holes change the flow direction and position of the fertilizer when it passes through the guide plate 23, so that the fertilizer at different positions can be mixed, thereby further reducing the fertilizer segregation phenomenon, making the fertilizer more uniform during the downward transportation process, and improving the uniformity and accuracy of fertilization.

[0043] Combination Figure 5 and Figure 6As shown, in some embodiments, each material guiding plate 23 is rotatably arranged on the material guiding cylinder 2. The material guiding plate 23 abuts against the inner wall of the material guiding channel 21. The cigar tobacco root fertilizing device 110 further includes a first connecting member 3. Both the material guiding plate 23 and the inner wall of the material guiding channel 21 are connected to the first connecting member 3. The first connecting member 3 is configured to limit the movement of the material guiding plate 23 and is further configured to fail when the weight of the fertilizer on the material guiding plate 23 is greater than a first preset value.

[0044] When the weight of the fertilizer on the material guiding plate 23 exceeds the first preset value, the first connecting member 3 fails, and the material guiding plate 23 starts to rotate under the action of the fertilizer, thereby disturbing the fertilizer in the material guiding channel 21, remixing the fertilizer with a segregation tendency, and thus improving the uniformity of the nutrient distribution in each layer of the soil.

[0045] When too much fertilizer accumulates on the material guiding plate 23 and the fertilizer accumulation is large, it may lead to too high a local fertilizer concentration and increase the risk of segregation. At this time, the rotation of the material guiding plate 23 can timely adjust the flow direction and flow rate of the fertilizer, disperse the excess fertilizer to other areas, make the distribution of the fertilizer in the material guiding channel 21 more uniform, and reduce the risk of segregation caused by local fertilizer concentration differences.

[0046] When the material guiding plate 23 rotates, a dynamic mixing area will be formed in the material guiding channel 21. When the fertilizer passes through this mixing area, it will be stirred by the material guiding plate 23, thereby achieving more sufficient mixing. This can break the agglomeration or stratification phenomena that may form between fertilizer particles, enabling fertilizers with different components to be more evenly distributed in the entire fertilizer flow, and effectively reducing the degree of fertilizer segregation.

[0047] As an example, the failure of the first connecting member 3 can be the damage of the first connecting member 3 or the disconnection of the first connecting member 3 from at least one of the inner wall of the material guiding plate 23 and the material guiding channel 21.

[0048] The first preset value can be determined according to the actual situation. For example, the first preset value is the weight when the fertilizer accumulation is large enough to cause a segregation risk.

[0049] Combined with Figure 2 、 Figure 3 and Figure 4As shown, in some embodiments, each material guiding plate 23 includes a first material guiding portion 231 and a second material guiding portion 232 which are oppositely arranged. The first material guiding portion 231 and the second material guiding portion 232 are oppositely arranged and are in abutting connection with each other in a separable manner. The cigar tobacco root fertilizing device 110 further includes a second connecting member 4. Both the first material guiding portion 231 and the second material guiding portion 232 are connected to the second connecting member 4. The second connecting member 4 is configured to limit the movement of the first material guiding portion 231 and the second material guiding portion 232, and the second connecting member 4 is further configured to fail when the weight of the fertilizer on the material guiding plate 23 is greater than a second preset value.

[0050] When too much fertilizer accumulates on the material guiding plate 23 and the fertilizer accumulation is large, it may cause too high local fertilizer concentration and increase the risk of segregation. At this time, the second connecting member 4 fails, and the first material guiding portion 231 and the second material guiding portion 232 move, which can timely adjust the flow direction and flow rate of the fertilizer, disperse the excess fertilizer to other areas, make the distribution of the fertilizer in the material guiding channel 21 more uniform, and reduce the segregation risk caused by the local fertilizer concentration difference.

[0051] As an example, the failure of the second connecting member 4 can be the damage of the second connecting member 4, or the second connecting member 4 releases the connection relationship with at least one of the inner walls of the material guiding plate 23 and the material guiding channel 21.

[0052] The second preset value can be determined according to the actual situation. For example, the second preset value is the weight when the fertilizer accumulation is large enough to cause the segregation risk.

[0053] Combined with Figure 2 、 Figure 3 and Figure 4 As shown, in some embodiments, the material guiding plate 23 further includes a rotating shaft 233 disposed in the material guiding channel 21 and connected to the material guiding cylinder 2. One end of the first material guiding portion 231 and one end of the second material guiding portion 232 are both rotatably connected to the rotating shaft 233 and are in abutting connection with each other in a separable manner.

[0054] The first material guiding portion 231 and the second material guiding portion 232 are connected to the material guiding cylinder 2 through the rotating shaft 233 and are rotatable. After the second connecting member 4 fails, the first material guiding portion 231 and the second material guiding portion 232 rotate, which can provide a guiding effect for the excess fertilizer and disperse it to other areas, make the distribution of the fertilizer in the material guiding channel 21 more uniform, and reduce the segregation risk caused by the local fertilizer concentration difference.

[0055] As Figure 1 shown, in some embodiments, the plurality of discharge ports 22 are at least three discharge ports 22.

[0056] At least three discharge ports 22 enable the fertilizer to be output from multiple different positions, so as to more widely cover the root area of cigar tobacco. Each discharge port 22 applies fertilizer within a certain range, making the fertilizer more evenly distributed in the soil, avoiding the situation of excessive or insufficient fertilizer locally, which is beneficial for the root system of cigar tobacco to evenly absorb nutrients, promotes the overall balanced growth of the plant, and thus improves the uniformity of nutrient distribution in each layer of the soil.

[0057] In some embodiments, the diameter of the discharge port 22 is greater than or equal to 3 cm.

[0058] The diameter of the discharge port 22 being greater than or equal to 3 cm can reduce the probability of the discharge port 22 being blocked by fertilizer, enabling the fertilizer to be smoothly discharged from the discharge port 22.

[0059] As Figure 7 shown, the cigar tobacco root fertilization system 100 of the embodiment of the present application includes: the cigar tobacco root fertilization device 110 as described in the above embodiment, a soil humidity sensor, and a controller 120. The soil humidity sensor is arranged in the material guiding cylinder 2. The controller 120 is electrically connected to the soil humidity sensor. The soil humidity information is obtained in real time through the soil humidity sensor, and the drilling depth can be judged according to the soil humidity information through the controller 120.

[0060] The cigar tobacco root fertilization system 100 of the embodiment of the present application includes: the cigar tobacco root fertilization device 110 as described in the above embodiment. A material guiding channel 21 for transporting fertilizer is defined in the material guiding cylinder 2, enabling the fertilizer to have a relatively fixed path during transportation, reducing the probability of segregation caused by mutual collision, friction between fertilizer particles, and interference by external factors. The fertilizer flows as a whole in the channel, avoiding the segregation phenomenon caused by the difference in the movement speed of different fertilizer particles. A plurality of discharge ports 22 are arranged at intervals in the length direction of the material guiding cylinder 2, enabling the fertilizer to be evenly discharged at different positions. The discharge ports 22 arranged at intervals can make the fertilizer more evenly distributed in the soil, reducing the probability of local fertilizer accumulation or excessive concentration, and thus improving the uniformity of nutrient distribution in each layer of the soil. Moreover, even if the fertilizer has a slight segregation tendency in the material guiding channel 21, through the dispersed discharge of the plurality of discharge ports 22, the influence on the fertilization uniformity can be reduced, making the fertilizer closer to uniform distribution in the soil, and thus improving the uniformity of nutrient distribution in each layer of the soil.

[0061] 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, a feed inlet for introducing fertilizer, and a discharge outlet for discharging fertilizer. Both the feed inlet and the discharge outlet are in communication with the installation cavity, and the discharge outlet is connected to the material guiding channel 21 through a flexible pipe; the crushing roller is rotatably arranged on the frame and located in the installation cavity, and the crushing roller is used for crushing agglomerated fertilizer; the crushing blades are rotatably arranged on the frame and located in the installation cavity, and the crushing blades are used for crushing agglomerated fertilizer.

[0062] During the storage and transportation of fertilizer, it is easy to agglomerate due to reasons such as moisture absorption and extrusion. The crushing roller and the crushing blades can effectively crush the agglomerated fertilizer. Through the rolling of the crushing roller and the cutting of the crushing blades, the large pieces of fertilizer are crushed into particles with appropriate particle sizes, so that when the fertilizer is transported to the periphery of the cigar tobacco roots through the material guiding channel, the particle sizes of the fertilizer are relatively uniform, avoiding too high or too low local fertilizer concentration caused by fertilizer agglomeration, ensuring the uniformity of fertilization, and being beneficial to the uniform absorption of nutrients by the cigar tobacco roots.

[0063] After the crushing device 130 crushes the agglomerated fertilizer, the fertilizer can smoothly enter the material guiding channel 21 through the flexible pipe and be discharged from the discharge port 22, thereby reducing the risk of blocking the discharge port 22, and further ensuring the continuity and stability of the fertilization process. In addition, the crushing device 130 can maintain the fertilizer at an appropriate particle size, so that the flow characteristics of the fertilizer in the material guiding channel remain stable.

[0064] The above are only the preferred specific embodiments 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.
