Description

Technical Field

[0001] This utility model belongs to the field of green plant maintenance technology, and specifically relates to an implantable slow-release nutrient post for colorful foliage trees. Background Technology

[0002] Colorful foliage trees, with their vibrant and varied leaf colors, have become an important element in urban greening and landscaping. To maintain and enhance leaf color, these tree species are highly sensitive to precise and continuous nutrient supply, especially micronutrients such as iron, manganese, and zinc. Therefore, implanted nutrient stake technology, which can directly act on the root system and reduce nutrient loss, is increasingly being applied in the refined maintenance of colorful foliage trees.

[0003] Nutrient release from existing nutrient stumps primarily relies on soil moisture to trigger fertilizer dissolution, with the dissolution rate showing a significant positive correlation with soil moisture. During the rainy season, the soil remains in a state of high humidity for extended periods, easily leading to rapid and excessive dissolution of fertilizer within the nutrient stumps, far exceeding the physiological needs of colorful-leaved trees. This phenomenon of "over-fertilization" not only wastes nutrient resources but also directly harms the growth of colorful-leaved trees—excessive soluble nutrients can cause an imbalance in the osmotic pressure of root cells, inducing root rot; simultaneously, unabsorbed excess nutrients are leached into deeper soil layers or flow into water bodies with rainwater, significantly exacerbating the risks of soil salinization and water eutrophication. Utility Model Content

[0004] To address the problem of "over-fertilization" in nutrient piles during the rainy season, this invention proposes an implantable slow-release nutrient pile for colorful foliage trees to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an implantable slow-release nutrient stake for colorful foliage trees, including a protective cylinder, a sleeve assembly inside the protective cylinder, a nutrient stake on the outer surface of the sleeve assembly, a pushing assembly on the top of the sleeve assembly, a rotating assembly between the pushing assembly and the sleeve assembly, and a support insertion assembly on the outer surface of the protective cylinder.

[0007] The supporting plug assembly is used to support the protective cylinder, and the pushing assembly is used to drive the sleeve assembly to move upward so that the nutrient pile moves into the protective cylinder under the drive of the sleeve assembly. At the same time, under the drive of the rotating assembly, the sleeve assembly can rotate and move up and down.

[0008] Furthermore, the socket assembly includes a movable disk, which is movably connected to the protective cylinder. A connecting rod is provided at the bottom of the movable disk, and the nutrient pile is disposed on the outer surface of the connecting rod. An insertion groove is provided on the outer surface of the connecting rod, and two insertion grooves are symmetrically arranged. An insertion block is movably connected inside the insertion groove, and an arc-shaped fixing plate is fixedly connected to the outer surface of the insertion block. The arc-shaped fixing plate is fixedly installed on the bottom of the movable disk.

[0009] Furthermore, the pushing assembly includes a pushing screw, which is rotatably connected to the protective cylinder. A pushing disk is threadedly connected to the outer surface of the pushing screw, and the pushing disk is disposed on the top of the movable disk. A receiving groove is provided inside the connecting rod, which passes through the movable disk and the pushing disk. The pushing screw is movably connected to the receiving groove.

[0010] Furthermore, the inner wall of the protective cylinder is provided with a guide groove, and a guide block is movably connected inside the guide groove. The guide block is fixedly connected to the push plate, and the top end of the push screw passes through the protective cylinder and is fixedly connected to a turntable.

[0011] Furthermore, the rotating assembly includes a polygonal limiting groove, which is formed at the bottom of the push screw. A polygonal limiting post is fixedly connected to the bottom of the inner wall of the receiving groove. The polygonal limiting post is movably connected to the polygonal limiting groove. A T-shaped rotating groove is formed at the top of the moving disk. A T-shaped rotating ring is movably connected inside the T-shaped rotating groove. The T-shaped rotating ring is fixedly connected to the push disk. A drill bit is fixedly connected to the bottom end of the connecting rod.

[0012] Furthermore, the support plug assembly includes a support disk, which is fixedly connected to the outer surface of the protective cylinder, and a plurality of tapered plugs are fixedly connected to the bottom of the support disk.

[0013] Furthermore, a sleeve is movably connected to the outer surface of the connecting rod, and the nutrient pile is disposed on the outer surface of the sleeve.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model rotates the pushing component, which in turn moves the sleeve component. Simultaneously, the nutrient pile inside the soil can move into the protective cylinder under the action of the sleeve component, thus allowing the protective cylinder to shield the nutrient pile. The above arrangement ensures that during the rainy season, the nutrient pile will not be in the soil with excessively high humidity for a long time, effectively preventing the phenomena of "over-fertilization", soil salinization and water eutrophication caused by this.

[0016] 2. In this utility model, when the push screw is rotated and the push plate pushes the connecting rod and the nutrient pile downward through the moving plate, the polygonal limiting post can move inside the polygonal limiting groove. At this time, the rotating push screw can drive the connecting rod to rotate through the polygonal limiting groove and the polygonal limiting post, so that the connecting rod and the drill bit at its bottom can rotate downward. This rotating drilling action makes it easier for the connecting rod to drive the nutrient pile deeper into the soil.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0028] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0029] Please see Figures 1-6 As shown, this utility model is an implantable slow-release nutrient stake for colorful foliage trees, including a protective cylinder 1, a sleeve assembly 2 is provided inside the protective cylinder 1, a nutrient stake 3 is provided on the outer surface of the sleeve assembly 2, a pushing assembly 4 is provided on the top of the sleeve assembly 2, a rotating assembly 5 is provided between the pushing assembly 4 and the sleeve assembly 2, and a support insertion assembly 6 is provided on the outer surface of the protective cylinder 1.

[0030] The supporting plug-in assembly 6 is used to support the protective cylinder 1, and the pushing assembly 4 is used to drive the sleeve assembly 2 to move upward so that the nutrient pile 3 moves into the interior of the protective cylinder 1 under the drive of the sleeve assembly 2. At the same time, under the drive of the rotating assembly 5, the sleeve assembly 2 can rotate and move up and down.

[0031] By inserting the protective cylinder 1 and the support connector 6 into the soil near the roots of the colorful-leaved tree, and then rotating the pushing component 4, the pushing end of the pushing component 4 can push the nutrient pile 3 downward through the sleeve component 2. During this process, the pushing component 4 can drive the sleeve component 2 to rotate through the rotating component 5, thereby causing the sleeve component 2 to drive the nutrient pile 3 to rotate into the soil. When the rainy season arrives, by rotating the pushing component 4 in the opposite direction, the sleeve component 2 can drive the nutrient pile 3 to move back into the protective cylinder 1.

[0032] By rotating the pushing component 4, the pushing component 4 drives the connecting component 2 to move. At the same time, the nutrient pile 3 inside the soil can move into the protective cylinder 1 under the action of the connecting component 2, so that the protective cylinder 1 can shield the nutrient pile 3. The above arrangement ensures that the nutrient pile will not be in the soil with excessive moisture for a long time during the rainy season, effectively preventing the phenomena of "over-fertilization", soil salinization and water eutrophication caused by this.

[0033] In one embodiment, the socket assembly 2 includes a movable disk 201, which is movably connected to the protective cylinder 1. A connecting rod 202 is provided at the bottom of the movable disk 201, and the nutrient pile 3 is provided on the outer surface of the connecting rod 202. An insertion groove 203 is provided on the outer surface of the connecting rod 202. Two insertion grooves 203 are symmetrically arranged. An insertion block 204 is movably connected inside the insertion groove 203. An arc-shaped fixing plate 205 is fixedly connected to the outer surface of the insertion block 204. The arc-shaped fixing plate 205 is fixedly installed on the bottom of the movable disk 201.

[0034] By fitting the nutrient pile 3 onto the outer surface of the connecting rod 202, then moving the two plug blocks 204 into the corresponding plug slots 203, and fitting the two arc-shaped fixing plates 205 onto the outer surface of the connecting rod 202, and then installing the two arc-shaped fixing plates 205 at the bottom of the moving plate 201 with fixing bolts; the above installation method ensures that the nutrient pile 3 is not obstructed when moving from the top of the connecting rod 202 to the outer surface of the connecting rod 202, and the connection between the connecting rod 202 and the moving plate 201 is relatively firm, thereby ensuring the stability of the moving plate 201 when pushing the nutrient pile 3 through the connecting rod 202.

[0035] In one embodiment, the aforementioned pushing component 4 includes a pushing screw 401, which is rotatably connected to the protective cylinder 1. A pushing disk 402 is threadedly connected to the outer surface of the pushing screw 401. The pushing disk 402 is disposed on the top of the movable disk 201. A receiving groove 403 is provided inside the connecting rod 202. The receiving groove 403 passes through the movable disk 201 and the pushing disk 402. The pushing screw 401 is movably connected to the receiving groove 403.

[0036] By rotating the push screw 401, the rotating push screw 401 can drive the push disk 402 to move inside the protective cylinder 1. At this time, the push disk 402 can drive the moving disk 201 to move synchronously inside the protective cylinder 1. As the moving disk 201 moves continuously, the connecting rod 202 can move on the outer surface of the push screw 401 through the storage groove 403. This setting allows the connecting rod 202 to move normally inside the protective cylinder 1, so that the protective cylinder 1 can normally store and protect the nutrient pile 3 on the outer surface of the connecting rod 202.

[0037] In one embodiment, for the protective cylinder 1, the inner wall of the protective cylinder 1 is provided with a guide groove 404, and a guide block 405 is movably connected inside the guide groove 404. The guide block 405 is fixedly connected to the push disk 402, and the top end of the push screw 401 passes through the protective cylinder 1 and is fixedly connected to a turntable 406.

[0038] The drive screw 401 can be rotated relatively easily by the turntable 406; when the drive screw 401 drives the drive disk 402, the drive disk 402 can drive the guide block 405 to slide inside the guide groove 404. At this time, the guide block 405 can guide the moving drive disk 402 through the guide groove 404, so that the drive disk 402 will not rotate with the drive screw 401.

[0039] In one embodiment, the rotating component 5 includes a polygonal limiting groove 501, which is formed at the bottom of the push screw 401. A polygonal limiting post 502 is fixedly connected to the bottom of the inner wall of the receiving groove 403. The polygonal limiting post 502 is movably connected to the polygonal limiting groove 501. A T-shaped rotating groove 503 is formed at the top of the moving disk 201. A T-shaped rotating ring 504 is movably connected inside the T-shaped rotating groove 503. The T-shaped rotating ring 504 is fixedly connected to the push disk 402. A drill bit 505 is fixedly connected to the bottom end of the connecting rod 202.

[0040] When the push screw 401 rotates and pushes the connecting rod 202 downward through the push disk 402 and the moving disk 201, the polygonal limiting post 502 can move inside the polygonal limiting groove 501. Simultaneously, the rotating push screw 401 drives the connecting rod 202 to rotate through the polygonal limiting groove 501 and the polygonal limiting post 502, thus allowing the connecting rod 202 and the drill bit 505 at its bottom to rotate downwards. The continuously rotating drill bit 505 then causes the connecting rod 202 to move downwards. The maintenance pile 3 moves into the soil with less effort. During the above operation, the T-shaped rotating groove 503 on the moving disk 201 can rotate on the outer surface of the T-shaped rotating ring 504 under the drive of the connecting rod 202. The T-shaped rotating groove 503 and the T-shaped rotating ring 504 make the connection between the moving disk 201 and the pushing disk 402 more secure, so that the pushing disk 402 can push and pull the moving disk 201 normally. At the same time, the connecting rod 202 at the bottom of the moving disk 201 can rotate normally.

[0041] In one embodiment, the support plug-in assembly 6 includes a support disk 601 fixedly connected to the outer surface of the protective cylinder 1, and a plurality of tapered plugs 602 fixedly connected to the bottom of the support disk 601.

[0042] When the lower side of the protective cylinder 1 is inserted into the soil by the drill bit 505, the protective cylinder 1 can drive several conical inserts 602 to move downwards synchronously through the support plate 601, so that the conical inserts 602 can be inserted into the soil synchronously. The setting of several conical inserts 602 ensures that the protective cylinder 1 will not tilt when it is working. At the same time, when the drive screw 401 is rotated by the turntable 406, the protective cylinder 1 will not shake.

[0043] In one embodiment, for the connecting rod 202, a sleeve 7 is movably connected to the outer surface of the connecting rod 202, and the nutrient pile 3 is disposed on the outer surface of the sleeve 7.

[0044] After the sleeve 7 is moved to the outer surface of the connecting rod 202 and the connecting rod 202 is installed at the bottom of the moving disk 201, the top and bottom of the sleeve 7 come into contact with the bottom of the arc-shaped fixing plate 205 and the top of the drill bit 505, respectively. At this time, the arc-shaped fixing plate 205 and the drill bit 505 can fix the nutrient pile 3 through the sleeve 7, so that no matter what degree the nutrient pile 3 dissolves, its whole body can always be on the outer surface of the connecting rod 202.

[0045] Through the above technical solution, 1. By rotating the pushing component 4, the pushing component 4 drives the connecting component 2 to move. Simultaneously, the nutrient pile 3 inside the soil can move into the protective cylinder 1 under the influence of the connecting component 2, thus allowing the protective cylinder 1 to shield the nutrient pile 3. This arrangement ensures that during the rainy season, the nutrient pile will not be exposed to excessively moist soil for extended periods, effectively preventing "over-fertilization," soil salinization, and eutrophication of water bodies. 2. By rotating the pushing screw 401... When the screw rotates and the pusher 402 pushes the connecting rod 202 and the nutrient pile 3 downward through the moving disc 201, the polygonal limiting post 502 can move inside the polygonal limiting groove 501. At this time, the rotating pusher 401 can drive the connecting rod 202 to rotate through the polygonal limiting groove 501 and the polygonal limiting post 502, so that the connecting rod 202 and the drill bit 505 at its bottom can rotate downward. This rotating drilling action makes it easier for the connecting rod 202 to drive the nutrient pile 3 deeper into the soil.
