Description

Technical Field

[0001] This utility model relates to the field of citrus planting technology, specifically to an intelligent and precise fertilizer application device for citrus planting. Background Technology

[0002] Citrus is a general term encompassing oranges, tangerines, mandarins, kumquats, pomelos, and trifoliate oranges. The selection of citrus varieties should be based on local climate and soil conditions, choosing areas with good drainage and irrigation, and convenient transportation. Pit cultivation can be reformed to deep trench cultivation, controlling the depth of the planting trenches. Terracing can be used for planting on slopes, controlling the number of plants per square meter. Different types of fertilizers should be applied according to the citrus's growth cycle and needs, such as fertilizers to promote shoot growth, fruit setting, fruit strengthening, and decomposing agents.

[0003] For example, the patent application number published on the China Patent Network is 202310403813.4, and the patent name is: A tiered fertilization device and fertilization method for citrus trees. It includes a fertilizer mixing mechanism, a main valve, a fertilizer and water delivery pipe, a ground fertilization mechanism, a soil tiered fertilization mechanism, a fertilizer and water recovery tank, and a recovery valve. The fertilizer mixing mechanism is connected to the fertilizer and water delivery pipe through the main valve, and the other end of the fertilizer and water delivery pipe is connected to the ground fertilization mechanism. One end of the soil tiered fertilization mechanism is connected to the ground fertilization mechanism, and the other end is fixedly installed in the soil. The fertilizer and water recovery tank is connected to the fertilizer and water delivery pipe through the recovery valve. This invention can fertilize the root system of citrus trees at different depths in the planting soil without having to dig fertilization trenches multiple times. This effectively reduces labor intensity and labor costs, and avoids the technical problem of citrus tree root breakage caused by multiple fertilization trench digging, which affects the absorption of nutrients by citrus trees, thereby reducing the quality of citrus and the yield.

[0004] However, the existing fertilization devices have a relatively simple structure. Citrus roots are well-developed, and the utilization rate of fertilizers of different concentrations varies depending on the root depth. Direct irrigation with mixed fertilizers cannot meet the utilization needs of the root system.

[0005] Therefore, it is necessary to design and modify the fertilizer application device for intelligent and precise control in citrus cultivation. Summary of the Invention

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an intelligent and precise fertilizer application device for citrus cultivation. This device has the advantage of improving the irrigation control effect of fertilizers at different depths, and solves the problem that existing fertilizer application devices have a relatively simple structure, citrus roots are well-developed, and the utilization rate of fertilizers of different concentrations varies among roots at different depths. Directly mixing and irrigating fertilizers cannot meet the utilization needs of the roots.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an intelligent and precise fertilizer application device for citrus cultivation, comprising a conical sleeve;

[0008] The conical sleeve can be inserted into the soil near the citrus rootstock. The conical sleeve is conical and hollow inside. The surface of the conical sleeve has several holes, which are arranged around the surface of the conical sleeve. The number of holes on the surface of the conical sleeve gradually decreases from top to bottom. The conical sleeve has an adjustment structure inside, which can control the amount of fertilizer that seeps into the holes.

[0009] As a preferred embodiment of this utility model, the adjusting structure includes an inner cylinder disposed inside the conical sleeve. The outer surface of the inner cylinder is completely fitted with the inner wall of the conical sleeve. The surface of the inner cylinder is set to be hollow. The interior of the inner cylinder can communicate with the hole. The inner cylinder can change the communication area with the hole by rotating.

[0010] In a preferred embodiment of this invention, a rotating wheel is fixedly connected to the top of the inner cylinder, a shaft is fixedly connected to the inside of the rotating wheel, a gear is fixedly connected to the surface of the shaft, a connecting frame is fixedly connected to the top of the conical sleeve, a screw is movably connected to the inside of the connecting frame via a bearing, a bracket is threadedly connected to the surface of the screw, and a toothed plate located on one side of the gear is fixedly connected to the top of the bracket, with the toothed plate and the gear meshing with each other.

[0011] As a preferred embodiment of this utility model, a drive motor is fixedly connected to one side of the connecting frame, and the output end of the drive motor is connected to the end of the screw near the drive motor.

[0012] As a preferred embodiment of this invention, a protective cover is fixedly connected to the top of the conical sleeve, and the adjusting structure, connecting frame, gear, and toothed plate are all located inside the protective cover.

[0014] In a preferred embodiment of this invention, a force-bearing rod is fixedly connected to one end of the claw near the conical sleeve, and push rods are fixedly connected to both sides of the top of the bracket. The side of the push rod away from the bracket contacts the surface of the force-bearing rod, and the push rod can squeeze the force-bearing rod as it moves horizontally with the bracket.

[0015] As a preferred embodiment of this invention, the surface of the push rod is fitted with a sleeve, and the outer surface of the sleeve is in contact with the surface of the force-bearing rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This utility model uses a conical structure to match the vertical distribution characteristics of citrus roots. The gradient design of the number of holes (more at the top and fewer at the bottom) corresponds to the rule that shallow roots need more fertilizer and deep roots need less fertilizer, so as to achieve precise fertilization in layers. By adjusting the structure, the amount of fertilizer penetration is dynamically controlled, avoiding excessive fertilization that pollutes the soil or insufficient fertility that affects growth.

[0021] 5. This utility model isolates rainwater, dust and corrosive substances through a protective cover, protecting the transmission mechanism and motor, extending the life of the device, preventing operators from accidentally touching moving parts, and reducing safety hazards.

[0022] 6. This utility model uses claws to hold the tree trunk, preventing the conical sleeve from shifting due to soil loosening or irrigation water impact. The claws swing around the pin shaft to adapt to tree trunks of different thicknesses, thus improving the versatility of the device.

[0023] 7. This utility model uses a push rod to push the force rod synchronously when the support moves, forcing the cleats to tighten towards the tree trunk. This adjusts the fertilization intensity while enhancing the stability of the device. The clamping force automatically increases with the rotation angle of the inner cylinder, i.e. the amount of fertilizer applied, thus preventing the device from loosening during high-flow fertilization.

[0024] 8. This utility model uses a sleeve as a buffer layer to reduce the direct friction between the push rod and the force-bearing rod, extend the service life of the component, and increase the contact area of ​​the sleeve so that the force-bearing rod is subjected to force evenly, avoiding local deformation or jamming.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 4 As shown, the present invention provides an intelligent and precise fertilizer application device for citrus cultivation, comprising a conical sleeve 1;

[0032] The conical sleeve 1 can be inserted into the soil near the citrus rootstock. The conical sleeve 1 is conical and hollow inside. Several holes 2 are opened on the surface of the conical sleeve 1. The number of holes 2 is several and surrounds the surface of the conical sleeve 1. The number of holes 2 on the surface of the conical sleeve 1 gradually decreases from top to bottom. An adjustment structure 3 is set inside the conical sleeve 1. The adjustment structure 3 can control the amount of fertilizer that seeps into the holes 2.

[0033] refer to Figure 3 The adjusting structure 3 includes an inner cylinder 4 disposed inside the conical sleeve 1. The outer surface of the inner cylinder 4 is completely fitted with the inner wall of the conical sleeve 1. The surface of the inner cylinder 4 is set to be hollow. The interior of the inner cylinder 4 can communicate with the hole 2. The inner cylinder 4 can change the communication area with the hole 2 by rotating.

[0034] As a technical optimization of this utility model, the overlapping area of ​​the hollow part and the hole 2 changes dynamically when the inner cylinder 4 is rotated, so as to accurately control the fertilizer release amount of the hole 2 at different depths. The inner cylinder 4 is completely fitted with the inner wall of the conical sleeve 1 to prevent fertilizer from directly leaking through the hole 2 and to ensure the maximum utilization rate of fertilizer.

[0035] refer to Figure 3A rotating wheel 5 is fixedly connected to the top of the inner cylinder 4. A shaft 6 is fixedly connected inside the rotating wheel 5. A gear 7 is fixedly connected to the surface of the shaft 6. A connecting frame 8 is fixedly connected to the top of the tapered sleeve 1. A screw 9 is movably connected inside the connecting frame 8 through a bearing. A bracket 10 is threadedly connected to the surface of the screw 9. A toothed plate 11 located on one side of the gear 7 is fixedly connected to the top of the bracket 10. The toothed plate 11 and the gear 7 mesh with each other.

[0036] As a technical optimization of this utility model, the screw 9 rotates to drive the bracket 10 to move horizontally, and the linear motion is converted into the rotation of the inner cylinder 4 by the meshing of the toothed plate 11 and the gear 7, so as to achieve precise angle adjustment. Driven by the screw 9, the rotation of the inner cylinder 4 can be completed without complicated tools, reducing the intensity of manual operation.

[0037] refer to Figure 3 A drive motor 12 is fixedly connected to one side of the connecting frame 8, and the output end of the drive motor 12 is connected to the end of the screw 9 near the drive motor 12.

[0038] As a technical optimization of this utility model, the screw 9 is rotated by the drive motor 12 to realize the automation of the inner cylinder 4 angle adjustment, which supports remote or programmed control. The motor drive adjustment speed is fast, adapts to real-time soil fertility monitoring data, and dynamically optimizes the fertilization strategy.

[0039] refer to Figure 1 The top of the conical sleeve 1 is fixedly connected to a protective cover 13, and the adjusting structure 3, the connecting frame 8, the gear 7 and the toothed plate 11 are all located inside the protective cover 13.

[0040] As a technical optimization of this utility model, the protective cover 13 isolates rainwater, dust and corrosive substances, protects the transmission mechanism and motor, extends the life of the device, prevents operators from accidentally touching moving parts, and reduces safety hazards.

[0041] refer to Figure 3 Both sides of the top of the conical sleeve 1 are movably connected to the claws 14 by pins. The side of the claws 14 away from the conical sleeve 1 can be sleeved on the surface of the citrus tree trunk by swinging.

[0042] As a technical optimization of this utility model, the tree trunk is clamped by the claw 14 to prevent the conical sleeve 1 from shifting due to soil loosening or irrigation water impact. The claw 14 swings around the pin shaft to adapt to tree trunks of different thicknesses, thereby improving the versatility of the device.

[0043] refer to Figure 4The end of the claw 14 near the conical sleeve 1 is fixedly connected to a force-bearing rod 15. Push rods 16 are fixedly connected to both sides of the top of the bracket 10. The side of the push rod 16 away from the bracket 10 contacts the surface of the force-bearing rod 15. The push rod 16 can squeeze the force-bearing rod 15 during the horizontal movement of the bracket 10.

[0044] As a technical optimization of this utility model, when the support 10 moves, the push rod 16 pushes the force rod 15 simultaneously, forcing the claw 14 to tighten towards the tree trunk, thereby adjusting the fertilization intensity and enhancing the stability of the device. The clamping force automatically increases with the rotation angle of the inner cylinder 4, i.e. the amount of fertilizer applied, thus preventing the device from loosening during high-flow fertilization.

[0045] refer to Figure 4 The surface of the push rod 16 is fitted with a sleeve 17, and the outer surface of the sleeve 17 is in contact with the surface of the force-bearing rod 15.

[0046] As a technical optimization of this utility model, the sleeve 17 is used as a buffer layer to reduce the direct friction between the push rod 16 and the force-bearing rod 15, thereby extending the service life of the component. The sleeve 17 increases the contact area, so that the force-bearing rod 15 is subjected to uniform force, avoiding local deformation or jamming.

[0047] The working principle and usage process of this utility model are as follows: The conical sleeve 1 is inserted into the soil near the citrus rootstock. Its conical structure adapts to the root distribution and ensures the stability of the device. The number of holes 2 on the surface of the conical sleeve 1 gradually decreases from top to bottom to match the tiered requirements of the citrus root system for fertilizer concentration, that is, the shallow root system needs a high concentration and the deep root system needs a low concentration.

[0048] When the conical sleeve 1 is inserted, the screw 9 is driven to rotate by the drive motor 12. The screw 9 is connected to the bracket 10 by a thread, which converts the rotational motion into the horizontal linear movement of the bracket 10. The toothed plate 11 at the top of the bracket 10 moves horizontally with the bracket 10 and meshes with the gear 7, which drives the gear 7 and the shaft 6 to rotate. The shaft 6 is fixedly connected to the rotating wheel 5, and the rotating wheel 5 drives the inner cylinder 4 to rotate synchronously.

[0049] The inner cylinder 4 has a hollow structure on its surface. The rotation angle determines the overlap area between the hollow part and the hole 2 of the conical sleeve 1. The upper layer has more holes 2 and a larger overlap area with the hollow part of the inner cylinder 4, resulting in a high fertilizer penetration in the shallow soil. The lower layer has fewer holes 2 and a smaller overlap area with the hollow part of the inner cylinder 4, resulting in a low fertilizer penetration in the deep soil.

[0050] When the support 10 moves horizontally, the push rod 16 at its top moves synchronously. The push rod 16 presses the force-bearing rod 15 on the claw 14 through the sleeve 17. After the force-bearing rod 15 is stressed, it pushes the claw 14 to swing around the pin axis towards the trunk, further clamping the trunk and preventing the device from tilting due to loose soil or external forces. At the same time, the claw 14 can measure the size of the trunk. When the trunk is thin, the rotation angle of the inner cylinder 4 is controlled by the motor, achieving synchronous adjustment of the rotation angle of the inner cylinder 4 to meet the needs of precise fertilization for roots at different depths.

[0051] In summary, this intelligent and precise fertilizer application device for citrus cultivation uses a conical structure to match the vertical distribution characteristics of citrus roots. The gradient design of the number of holes 2, with more holes at the top and fewer at the bottom, corresponds to the principle that shallow roots require more fertilizer and deep roots require less fertilizer, thus achieving precise stratified fertilization. By adjusting the structure 3, the amount of fertilizer penetration is dynamically controlled, avoiding excessive fertilization that pollutes the soil or insufficient fertility that affects growth.
