Abstract
Description
Technical Field
[0001] This application relates to the field of tobacco cultivation, and more particularly to a root fertilizer applicator for tobacco leaf cultivation. Background Technology
[0002] In tobacco cultivation, the growth status of tobacco leaves is closely related to nutrient supply. Root fertilization, as a key link in nutrient acquisition by tobacco leaves, directly affects the photosynthetic efficiency, dry matter accumulation, and ultimately, yield and quality. To ensure that tobacco leaves can efficiently absorb nutrients at different growth stages, it is necessary to achieve precise application and even distribution of fertilizer around the roots. Simultaneously, fertilization operations must be convenient and adaptable to meet the needs of large-scale cultivation.
[0003] Currently, fertilization of tobacco roots typically employs traditional methods such as manual watering or single-point injection via tubing, or uses simple fixed fertilization tools. These methods limit fertilization to a single point or localized area, making it difficult to achieve uniform fertilization of the surrounding ring area around the roots. This results in uneven nutrient absorption across different parts of the roots, affecting the uniformity of tobacco growth. Furthermore, traditional tools lack an adjustable opening and closing structure, making it impossible to adapt to the diameter differences of tobacco roots at different growth stages. During operation, problems arise such as the fertilization ring being too large, leading to fertilizer waste, or too small, damaging the root system.
[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content
[0005] To address the aforementioned issues, this application provides a tobacco root fertilizer applicator for tobacco cultivation, which can solve the problem of uneven nutrient absorption and is adaptable to different root diameters to avoid fertilizer waste or root damage.

[0038] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, they are provided so that this disclosure will be more comprehensive and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
[0039] Furthermore, the accompanying drawings are merely illustrative of this disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and therefore, repeated descriptions of them will be omitted.
[0040] This example embodiment first provides a tobacco root fertilizer applicator for tobacco cultivation. (Reference) Figures 1 to 4 As shown, the tobacco root fertilizer applicator for tobacco cultivation includes a fertilizer storage component 100, a fertilizer delivery component 200, a pushing component 300, and a fertilizer application component 400.
[0041] The fertilizer storage component 100 has an inner cavity, and the bottom of the inner cavity has a feed port for storing liquid fertilizer in the inner cavity and outputting it through the feed port.
[0042] The fertilizer conveying component 200 has one end connected to the conveying port and is used to convey liquid fertilizer in the fertilizer storage component 100.
[0043] The fertilizer application component 400 has a fertilizer application ring 410 that communicates with the other end of the fertilizer delivery component 200. The fertilizer application ring 410 has an opening at the end away from the fertilizer delivery component 200 for ring-shaped application of liquid fertilizer input from the fertilizer delivery component 200.
[0044] The pushing component 300 is slidably disposed on the fertilizer delivery component 200 and connected to one end of the fertilizer application component 400 near the fertilizer delivery component 200, and is used to open the opening of the fertilizer application ring 410 when pushed.
[0045] In one possible implementation, the fertilizer storage assembly 100 includes: a fertilizer storage box 110 and a carrying strap 120;
[0046] The feed inlet is located at the lower part of the fertilizer storage box 110, and has a shoulder strap 120 on the side near the fertilizer application component 400.
[0047] Understandably, the shoulder strap 120 of the fertilizer storage component 100 can distribute the weight of the fertilizer storage box 110 to the operator's shoulder, reduce hand fatigue, and improve operational mobility; the feed inlet is located at the bottom of the fertilizer storage box 110, and can also use the weight of the liquid to assist in fertilizer delivery, reducing fertilizer residue in the fertilizer storage box 110.
[0048] For example, the fertilizer storage tank 110 has a suction pump at its feed port for outputting liquid fertilizer from the feed port when the tank is opened.
[0049] It should be noted that the suction pump provides active power for the delivery of liquid fertilizer, overcomes the pipeline resistance of the fertilizer delivery component 200, and ensures a continuous and stable output of fertilizer. At the same time, by adjusting the power of the suction pump, the fertilizer delivery flow rate can be precisely controlled to meet the fertilization needs of tobacco leaves at different growth stages.
[0050] In one possible implementation, the fertilizer delivery assembly 200 includes: a first hose 210, a fertilizer delivery pipe 220, and a second hose 230;
[0051] One end of the first hose 210 is connected to the feed inlet, and the other end is connected to the fertilizer delivery pipe 220. The fertilizer delivery pipe 220 is connected to the fertilizer application ring 410 through the second hose 230.
[0052] It should be noted that the first hose 210 of the fertilizer delivery assembly 200 can be flexibly bent as the fertilizer storage tank 110 moves, avoiding damage to the connection of the delivery port due to force; the second hose 230 is adapted to the opening and closing action of the fertilizer ring 410, ensuring that fertilizer can still be continuously delivered to the fertilizer ring 410 through the fertilizer delivery pipe 220 when the fertilizer ring 410 is rotating.
[0053] In one possible implementation, the fertilization assembly 400 includes: a fertilization ring 410 and a gear 430;
[0054] The fertilizer application ring 410 is composed of two arc-shaped hollow tubes. The two arc-shaped hollow tubes are rotatably connected to the fertilizer delivery tube 220 at one end near the fertilizer delivery assembly 200 through a second rotating shaft 420. Each second rotating shaft 420 is equipped with a gear 430 and is fixedly connected to the arc-shaped hollow tube.
[0055] It should be noted that the two arc-shaped hollow tubes of the fertilizer application component 400 are rotatably connected to the fertilizer delivery tube 220 through the second rotating shaft 420, so that the opening of the fertilizer ring 410 can be opened and closed flexibly to adapt to the root of tobacco leaves of different diameters; the gear 430 on the second rotating shaft 420 is fixed to the arc-shaped hollow tube, providing a stable transmission structure for the opening and closing, and ensuring accurate power transmission.
[0056] Furthermore, the inner wall of the arc-shaped hollow tube has a fertilizer application hole 411.
[0057] It should be noted that the fertilizer application holes 411 on the inner side of the arc-shaped hollow tube allow liquid fertilizer to seep into the soil from multiple directions around the roots, ensuring that all areas of the roots are fertilized evenly; the inner side setting can reduce the waste caused by fertilizer being directly exposed to the external environment and improve fertilizer utilization.
[0058] In one possible implementation, the pushing assembly 300 includes a pushing rod 310, a first support member 320, and a rack 330;
[0059] The first support member 320 is fixedly mounted on the fertilizer delivery pipe 220. The push rod 310 is slidably connected to the first support member 320. The end near the fertilizer application component 400 has the rack 330, which meshes with the gear 430.
[0060] Furthermore, the rack 330 is fixedly connected to the push rod 310 via the second connector 340, and the second connector 340 is slidably connected to the fertilizer delivery assembly 200.
[0061] Understandably, the second connector 340 of the push assembly 300 securely connects the rack 330 to the push rod 310 to ensure effective transmission of thrust; at the same time, the sliding engagement between the second connector 340 and the fertilizer conveying assembly 200 can limit the movement trajectory of the rack 330, ensuring that the rack 330 always meshes precisely with the gear 430.
[0062] Optionally, the end of the push rod 310 away from the fertilizer assembly 400 has a push handle 370, and a return spring 380 is provided between the push handle 370 and the first support member 320.
[0063] Understandably, the push handle 370 of the push rod 310 increases the contact area with the hand, making it easier for the operator to apply force; the return spring 380 automatically drives the push rod 310 to return to its original position after the push handle 370 is released, driving the fertilizer ring 410 to close, facilitating continuous fertilization operations. The operator can also use their thumb to push the push handle 370 to drive the opening and closing of the fertilizer ring 410.
[0064] In one possible implementation, the fertilizer delivery assembly 200 has a first connector 240, and the arc-shaped hollow tube is rotatably connected to the first connector 240 via a second rotating shaft 420; each side of the push rod 310 has a first sliding shaft 350, and the two ends of the second connector 340 are slidably mounted on the first sliding shaft 350; the first sliding shaft 350 is fixedly connected to the first connector 240 via a second support 360.
[0065] Understandably, the first connector 240 of the fertilizer delivery assembly 200 provides a stable rotation fulcrum for the arc-shaped hollow tube, enhancing the structural rigidity of the fertilizer ring 410; the first sliding shaft 350 slides and guides the second connector 340 to prevent the rack 330 from shifting, ensuring stable and reliable transmission between the gear 430 and the rack 330.
[0066] Working principle:
[0067] The operator carries the fertilizer storage box 110 of the fertilizer storage component 100 on their back using a shoulder strap 120. The liquid fertilizer stored inside the fertilizer storage box 110 can be discharged through the bottom feed port. Before fertilization, the operator pushes the push rod 310 of the push component 300. The push rod 310 slides along the first support member 320, causing the rack 330 near one end of the fertilizer application component 400 to move. Since the rack 330 meshes with the gear 430 on the second rotating shaft 420 in the fertilizer application component 400, the movement of the rack 330 drives the gear 430 to rotate, which in turn causes the two arc-shaped hollow tubes fixedly connected to the gear 430 to rotate around the second rotating shaft 420, opening the opening of the fertilizer ring 410, making it easier to fit the fertilizer ring 410 around the root of the tobacco leaf.
[0068] After the ring is fitted, the operator releases the push rod 310, pushes the return spring 380 between the handle 370 and the first support 320 to reset, pulls the push rod 310 to move in the opposite direction, and the rack 330 resets with the push rod 310 and drives the gear 430 to rotate in the opposite direction, so that the two arc-shaped hollow tubes close and the fertilizer ring 410 fits against the soil around the roots of the tobacco leaves. At this time, the suction pump of the fertilizer storage box 110 is turned on, and the liquid fertilizer is transported in sequence through the first hose 210, the fertilizer delivery pipe 220 of the fertilizer delivery component 200, and the second hose 230 to the arc-shaped hollow tube of the fertilizer ring 410 under the action of the suction pump. Finally, it seeps out evenly through the fertilizer hole 411 on the inner side wall of the arc-shaped hollow tube, realizing the ring-shaped precise fertilization of the roots of the tobacco leaves.
