Description

Technical Field

[0001] This invention relates to the field of seedling fertilization devices, specifically a buried fertilization device for cultivating garden seedlings. Background Technology

[0002] In the process of cultivating garden seedlings, fertilization is a key link to ensure the growth and development of seedlings, improve seedling quality and survival rate. Seedlings need to continuously obtain macro-elements such as nitrogen, phosphorus and potassium, as well as micro-elements such as iron and zinc from the soil. Scientific and reasonable fertilization methods can not only meet the nutritional needs of seedlings at different growth stages, but also improve the physical and chemical properties of the soil, promote root development, and lay the foundation for the subsequent transplanting and long-term growth of seedlings.

[0003] With the development of the landscaping industry towards large-scale and refined operations, the requirements for fertilization techniques in seedling cultivation are increasing. Currently, the commonly used fertilization methods in landscaping seedling cultivation mainly include surface application, trench application, and hole application. Surface application is simple to operate and does not require complicated tools, but the fertilizer is directly exposed to the ground surface, making it susceptible to erosion by rainwater and wind, resulting in nutrient loss. At the same time, the amount of fertilizer volatilization is large, and the actual utilization rate is usually insufficient. This not only wastes resources but may also cause environmental problems such as eutrophication of surrounding water bodies due to nutrient loss. In addition, surface fertilizer is difficult to reach the root absorption layer of seedlings, resulting in low absorption efficiency and may stimulate excessive growth of surface roots, affecting deep root development and reducing the seedlings' resistance to adverse conditions.

[0004] Existing buried fertilization devices typically involve inserting a single insertion tube directly around the seedlings. The top of the insertion tube is then connected to a fertilizer delivery pipe via a flexible tube, which delivers the fertilizer to the vicinity of the seedling roots. However, existing insertion tubes cannot adjust the amount of fertilizer according to the seedlings' fertilizer requirements, and the single-insertion fertilization device also cannot adjust its fertilization range, thus its function is relatively limited. Summary of the Invention

[0005] Based on this, the purpose of this invention is to provide a buried fertilization device for cultivating garden seedlings, so as to solve the technical problem that the existing insertion tube cannot adjust the fertilizer according to the fertilizer requirements of the seedlings, and the single insertion fertilization device cannot adjust its fertilization range, thus its function is relatively simple.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a buried fertilization device for cultivating garden seedlings, comprising a main body, with multiple sets of auxiliary plates fixedly installed on the outer wall of the main body, a rotating mechanism inside the main body, a liquid flow mechanism inside the rotating mechanism, a sliding plate slidably connected to the outer wall of the main body, and an unfolding mechanism inside the auxiliary plates. The rotating mechanism includes an adjusting wheel, a rotating shaft, a lifting shaft, a blocking block, and a top block. The adjusting wheel is rotatably installed on the top of the main body, the top of the rotating shaft is fixedly installed inside the adjusting wheel, the bottom of the rotating shaft is slidably connected to the lifting shaft, a blocking block is fixedly installed on the outer wall of the bottom of the lifting shaft, and the top block is slidably installed at the bottom of the auxiliary plate. The rotating shaft and the lifting shaft work together to adjust the different states of the main body. The liquid flow mechanism includes an inner tube, which is located inside the rotating shaft and fixedly connected to the bottom of the main body. The inner tube serves to transport liquid fertilizer.

[0007] By adopting the above technical solution, this invention flexibly switches the fertilization state by rotating the adjustment wheel, achieving precise control of different drainage volumes to meet the diverse fertilization needs of seedlings. The auxiliary plate on the outer wall of the device helps the main body to quickly insert into the soil, reducing the difficulty of operation. During fertilization, the fertilizer can directly reach the root area of ​​the seedlings, ensuring efficient nutrient absorption and avoiding waste. By switching the adjustment mode, the unfolding mechanism can also be opened, using the soil-breaking plate to break open the surrounding soil, and with the help of a special flow channel, large-scale irrigation can be achieved. After irrigation, the sliding plate can fall naturally, and the unfolding mechanism can also be easily reset. This solves the technical problem that existing insertion tubes cannot adjust the fertilizer according to the fertilizer requirements of seedlings, and that single insertion fertilization devices cannot adjust their fertilization range, thus their functions are relatively limited.

[0008] Furthermore, the rotating mechanism also includes a first protruding block and a first movable block, wherein the first protruding block is fixedly installed on the top of the lifting shaft, and the first movable block is fixedly installed on the inner side of the sliding plate. The rotating mechanism also includes a second movable block, a second protruding block, and a connecting ring, wherein the second movable block is fixedly installed on the bottom of the lifting shaft, the connecting ring is located at the inner bottom end of the body, and the second movable block is slidably connected to the body. In addition, multiple sets of top blocks are fixedly installed on the outer wall of the connecting ring, and the second protruding block is fixedly installed on the inner side of the connecting ring.

[0009] By adopting the above technical solution, the rotation of the rotating shaft can drive the lifting shaft to rotate together. The first protrusion is installed on the top of the lifting shaft, so the first protrusion will rotate together with the lifting shaft. At this time, part of the first protrusion will move to the top of part of the first moving block, insert the body into the ground, and the sliding plate will cause the first moving block to move together with the first protrusion during the passive upward process, and then the lifting shaft will rise together.

[0010] Furthermore, the deployment mechanism includes a soil-breaking plate, which is rotatably mounted inside the auxiliary plate, and the bottom of the soil-breaking plate is inclined. The soil-breaking plate is located directly above the top block, and one side of the soil-breaking plate is conical. The conical design of the soil-breaking plate facilitates the breaking of the soil. The deployment mechanism also includes a connecting pipe, a liquid storage chamber, and a movable component. The movable component is fixedly mounted on the top of the outer wall of the rotating shaft. The movable component is located inside the liquid storage chamber, and the liquid storage chamber is rotatably connected to the movable component. Multiple sets of the connecting pipes are fixedly mounted at the bottom of the liquid storage chamber. The other end of the connecting pipe is fixedly connected to the top of the soil-breaking plate. The soil-breaking plate has a cavity inside, and the liquid storage chamber is connected to the soil-breaking plate through the connecting pipe.

[0011] By adopting the above technical solution, the adjusting wheel in the initial state is rotated 180 degrees. At this time, the first moving block will be located directly above the first protruding block, and the second moving block at the bottom of the lifting shaft will move directly below the second protruding block. Then, the main body is inserted into the ground, and the sliding plate is passively raised. Under the action of the second moving block and the second protruding block, the connecting ring and the top block are raised together. At this time, the top block will contact the bottom of the soil-breaking plate in the unfolding mechanism. The bottom of the soil-breaking plate is inclined, so the top block can smoothly push the soil-breaking plate open. One side of the soil-breaking plate is conical, which can quickly break the soil around the main body. When the adjusting wheel is rotated, the rotating shaft will rotate with the moving parts. After rotating 180 degrees, the second outlet will be exposed. At this time, the valve of the fertilizer pipe is opened, and some fertilizer will enter the storage chamber through the second outlet, and then enter the soil-breaking plate through the flexible connecting pipe. After that, it will be discharged into the ground from the third outlet, thereby carrying out large-scale irrigation.

[0012] Furthermore, the liquid flow mechanism also includes a first liquid outlet, which is located at the bottom of the main body, and the bottom end of the inner tube is located directly above the first liquid outlet. The liquid flow mechanism also includes a first outlet and a second outlet, wherein multiple sets of first outlets are located at the bottom end of the outer wall of the inner tube, and multiple sets of second outlets are located at the bottom end of the outer wall of the main body. The liquid flow mechanism also includes a second outlet and a third outlet, wherein the second outlet is located at the top end of the outer wall of the inner tube, and a cavity is provided on one side of the outer wall of the rotating shaft and the movable part, and the second outlet is connected to the liquid storage cavity through the cavity of the rotating shaft and the movable part. The third outlet is located at the bottom end of the soil-breaking plate.

[0013] By adopting the above technical solution, the valve of the fertilizer pipeline is opened, and the liquid fertilizer will enter the inner pipe through the hose, and then be discharged into the ground from the first outlet, or enter the body through the first outlet and then quickly flow out to the outside from the second outlet, or enter the storage chamber through the second outlet and then enter the soil breaking plate through the flexible connecting pipe, and then be discharged into the ground from the third outlet, thereby carrying out large-scale irrigation.

[0014] Furthermore, a pressure plate is fixedly installed on the top of the main body, and the pressure plate assists in inserting the main body into the soil.

[0015] By adopting the above technical solution, where the main body is manually inserted into the soil around the seedling by pressing down on the plate, the main body can be quickly inserted into the soil.

[0016] In summary, the present invention has the following beneficial effects: The present invention can flexibly switch the fertilization state by rotating the adjustment wheel to achieve precise control of different drainage volumes, meeting the diverse fertilization needs of seedlings. The auxiliary plate on the outer wall of the device can help the main body to quickly insert into the soil, reducing the difficulty of operation. During fertilization, the fertilizer can directly reach the root area of ​​the seedlings, ensuring efficient nutrient absorption and avoiding waste. By switching the adjustment mode, the unfolding mechanism can also be opened, using the soil-breaking plate to break open the surrounding soil, and with the help of the special flow channel, large-scale irrigation can be achieved. After irrigation, the sliding plate can fall naturally, and the unfolding mechanism can also be easily reset. This solves the technical problem that the existing insertion tube cannot adjust the fertilizer according to the fertilizer requirements of the seedlings, and the single insertion type fertilization device cannot adjust its fertilization range, so its function is relatively simple.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of the present invention will now be described.

[0030] A buried fertilization device for cultivating garden seedlings, such as Figure 1-10 As shown, it includes a main body 1, multiple sets of auxiliary plates 2 are fixedly installed on the outer wall of the main body 1, a rotating mechanism 3 is provided inside the main body 1, a liquid flow mechanism 4 is provided inside the rotating mechanism 3, a sliding plate 5 is slidably connected to the outer wall of the main body 1, an unfolding mechanism 7 is provided inside the auxiliary plates 2, and a lower pressing plate 6 is fixedly installed on the top of the main body 1, and the lower pressing plate 6 plays the role of assisting in inserting the main body 1 into the soil.

[0031] The top of the inner tube 401 is connected to the external liquid fertilizer pipeline through a hose. Before fertilizing, the user can adjust the fertilization status of the fertilization device through the rotating mechanism 3 on the top of the auxiliary plate 2. Depending on the seedlings, the user can adjust the main body 1 through the rotating mechanism 3 to switch the main body 1 to different irrigation states. The user can manually insert the main body 1 into the soil around the seedlings through the lower pressing plate 6. Since multiple sets of auxiliary plates 2 are installed on the outer wall of the main body 1, they can help the main body 1 to be quickly inserted into the soil.

[0032] Furthermore, the rotating mechanism 3 includes an adjusting wheel 301, a rotating shaft 302, a lifting shaft 303, a blocking block 304, and a top block 310. The adjusting wheel 301 is rotatably mounted on the top of the main body 1. The top end of the rotating shaft 302 is fixedly mounted inside the adjusting wheel 301. The bottom of the rotating shaft 302 is slidably connected to the lifting shaft 303. The blocking block 304 is fixedly mounted on the outer wall of the bottom of the lifting shaft 303. The top block 310 is slidably mounted on the bottom end of the auxiliary plate 2. The rotating shaft 302 and the lifting shaft 303 work together to adjust the different states of the main body 1. The liquid flow mechanism 4 includes an inner tube 401, which is located inside the rotating shaft 302 and is fixedly connected to the bottom end of the main body 1. The inner tube 401 serves to transport liquid fertilizer.

[0033] The adjustment wheel 301 is manually rotated 90 degrees. At this time, the inside of the adjustment wheel 301 is tightly connected to the rotating shaft 302. Therefore, the rotation of the adjustment wheel 301 will cause the rotating shaft 302 to rotate together. Multiple sets of guide side plates are set on the outside of the rotating shaft 302, and the lifting shaft 303 is located on the bottom outside of the rotating shaft 302. Therefore, the rotation of the rotating shaft 302 can cause the lifting shaft 303 to rotate together. When the valve of the external fertilizer pipe is opened, the liquid fertilizer will enter the inner pipe 401 through the hose, and then be discharged into the ground from the first liquid outlet 402. Some fertilizer will flow out from the first flow outlet 403 at the bottom of the inner pipe 401 into the bottom of the body 1. Since there is a blocking block 304 inside, this part of the fertilizer will only flow out from the first liquid outlet 402 into the ground, so as to irrigate the roots of the seedlings.

[0034] Furthermore, the deployment mechanism 7 includes a soil-breaking plate 701, which is rotatably installed inside the auxiliary plate 2. The bottom of the soil-breaking plate 701 is inclined, and the soil-breaking plate 701 is located directly above the top block 310. One side of the soil-breaking plate 701 is conical, and the conical design of the soil-breaking plate 701 facilitates breaking the soil. The deployment mechanism 7 also includes a connecting pipe 702, a liquid storage chamber 703, and a movable part 704. The movable part 704 is fixedly installed on the top of the outer wall of the rotating shaft 302. The movable part 704 is located inside the liquid storage chamber 703, and the liquid storage chamber 703 is rotatably connected to the movable part 704. Multiple sets of connecting pipes 702 are fixedly installed at the bottom of the liquid storage chamber 703. The other end of the connecting pipe 702 is fixedly connected to the top of the soil-breaking plate 701. The soil-breaking plate 701 has a cavity inside, and the liquid storage chamber 703 is connected to the soil-breaking plate 701 through the connecting pipe 702.

[0035] When the initial adjusting wheel 301 is rotated 180 degrees, the first moving block 306 will be directly above the first protrusion 305, and the second moving block 307 at the bottom of the lifting shaft 303 will move directly below the second protrusion 308. When the body 1 is inserted into the ground, the sliding plate 5 rises passively. Under the action of the second moving block 307 and the second protrusion 308, it rises together with the connecting ring 309 and the top block 310. At this time, the top block 310 will contact the bottom of the soil breaking plate 701 in the unfolding mechanism 7. Since the bottom of the soil breaking plate 701 is inclined, the top block 310 can smoothly push the soil breaking plate 701 open. One side of the soil breaking plate 701 is conical, which can quickly break the soil around the body 1.

[0036] In the example, the rotating mechanism 3 also includes a first protrusion 305 and a first moving block 306, wherein the first protrusion 305 is fixedly installed on the top of the lifting shaft 303, and the first moving block 306 is fixedly installed on the inner side of the sliding plate 5. The rotating mechanism 3 also includes a second moving block 307, a second protrusion 308 and a connecting ring 309, wherein the second moving block 307 is fixedly installed on the bottom of the lifting shaft 303, the connecting ring 309 is located at the inner bottom end of the body 1, and the second moving block 307 is slidably connected to the body 1. Furthermore, multiple sets of top blocks 310 are fixedly installed on the outer wall of the connecting ring 309, and the second protrusion 308 is fixedly installed on the inner side of the connecting ring 309.

[0037] The rotation of the rotating shaft 302 can cause the lifting shaft 303 to rotate together. The first protrusion 305 is installed on the top of the lifting shaft 303. Therefore, the first protrusion 305 will rotate together with the lifting shaft 303. At this time, part of the first protrusion 305 will move to the top of part of the first moving block 306. The body 1 is inserted into the ground. During the passive upward process of the sliding piece 5, the first moving block 306 will move together with the first protrusion 305, and then the lifting shaft 303 will rise together.

[0038] The liquid flow mechanism 4 also includes a first liquid outlet 402, which is located at the bottom of the body 1 and the bottom end of the inner tube 401 is located directly above the first liquid outlet 402. The liquid flow mechanism 4 also includes a first liquid outlet 403 and a second liquid outlet 404, wherein multiple sets of first liquid outlets 403 are located at the bottom end of the outer wall of the inner tube 401 and multiple sets of second liquid outlets 404 are located at the bottom end of the outer wall of the body 1. The liquid flow mechanism 4 also includes a second liquid outlet 405 and a third liquid outlet 406, wherein the second liquid outlet 405 is located at the top end of the outer wall of the inner tube 401, and a hole is provided on one side of the outer wall of the rotating shaft 302 and the movable part 704, and the second liquid outlet 405 is connected to the liquid storage chamber 703 through the hole of the rotating shaft 302 and the movable part 704. The third liquid outlet 406 is located at the bottom end of the soil breaking plate 701.

[0039] When the valve of the fertilizer pipeline is opened, the liquid fertilizer will enter the inner pipe 401 through the hose, and then be discharged into the ground from the first outlet 402, or enter the body 1 through the first outlet 403, and then quickly flow out to the outside from the second outlet 404, or enter the storage chamber 703 through the second outlet 405, and then enter the soil breaking plate 701 through the flexible connecting pipe 702, and then be discharged into the ground from the third outlet 406, thereby carrying out large-scale irrigation.

[0040] The working principle of this invention is as follows: When in use, the top of the inner tube 401 is first connected to the external liquid fertilizer pipeline through a hose. Before fertilizing, the user can adjust the fertilization status of the fertilization device through the rotating mechanism 3 on the top of the auxiliary plate 2.

[0041] Depending on the different seedlings, the user can adjust the main body 1 by rotating the mechanism 3 to switch the main body 1 to different irrigation states;

[0042] First, the user can manually rotate the adjusting wheel 301 to the minimum drainage state. At this time, the user can manually insert the main body 1 into the soil around the seedling by pressing down the plate 6. Since the outer wall of the main body 1 is equipped with multiple sets of auxiliary plates 2, it can help the main body 1 to be quickly inserted into the soil.

[0043] After the main body 1 is inserted into the soil for a certain distance, the sliding piece 5 will come into contact with the ground. The main body 1 will then continue to move into the soil, and the sliding piece 5 will be squeezed by the ground and passively slide upward on the outer wall of the main body 1.

[0044] At this time, the first moving block 306 inside the sliding piece 5 will not contact the first protrusion 305, so the sliding piece 5 will move independently;

[0045] At this point, simply open the valve of the external fertilizer pipe, and the liquid fertilizer will enter the inner pipe 401 through the hose, and then be discharged into the ground from the first outlet 402. Some of the fertilizer will flow out from the first outlet 403 at the bottom of the inner pipe 401 into the bottom of the main body 1. Because there is a blocking block 304 inside, this part of the fertilizer will only flow out from the first outlet 402 into the ground, so as to irrigate the roots of the seedlings.

[0046] If the user needs to adjust to a large amount of fluid discharge state, before inserting the main body 1, the adjusting wheel 301 can be rotated by glove to rotate it 90 degrees. At this time, the inside of the adjusting wheel 301 is tightly connected to the rotating shaft 302. Therefore, the rotation of the adjusting wheel 301 will cause the rotating shaft 302 to rotate together. Multiple sets of guide side plates are provided on the outside of the rotating shaft 302, and the lifting shaft 303 is located on the bottom outside of the rotating shaft 302. Therefore, the rotation of the rotating shaft 302 can cause the lifting shaft 303 to rotate together.

[0047] The first protrusion 305 is installed on the top of the lifting shaft 303, so the first protrusion 305 will rotate together with the lifting shaft 303. At this time, part of the first protrusion 305 will move to the top of part of the first moving block 306. When the user inserts the main body 1 again, the sliding piece 5 will move the first moving block 306 along with the first protrusion 305 during the passive upward process, and then the lifting shaft 303 will rise together.

[0048] After the 300 rotating mechanism 3 rises, the blocking block 304 at its bottom will also rise, thus exposing the second liquid outlet 404 opened on the outer wall of the main body 1. At this time, the fertilizer valve is opened, and the fertilizer will not only flow out from the first liquid outlet 402, but also enter the interior of the main body 1 through the first flow outlet 403, and then quickly flow out from the second liquid outlet 404 to the outside, so as to quickly irrigate the roots of the seedlings.

[0049] When the user needs to expand the irrigation range, the user can rotate the adjustment wheel 301 in the initial state by 180 degrees. At this time, the first moving block 306 will be located directly above the first protrusion 305, and the second moving block 307 at the bottom of the lifting shaft 303 will move directly below the second protrusion 308. At this time, the user can insert the main body 1 again.

[0050] When the sliding piece 5 rises passively, it will rise along with the connecting ring 309 and the top block 310 under the action of the second moving block 307 and the second protruding block 308.

[0051] At this time, the top block 310 will contact the bottom of the soil-breaking plate 701 in the unfolding mechanism 7. Since the bottom of the soil-breaking plate 701 is inclined, the top block 310 can smoothly push the soil-breaking plate 701 open.

[0052] The top of the soil-breaking plate 701 is connected to the inside of the auxiliary plate 2 via a rotating shaft. Therefore, as the top block 310 rises, the soil-breaking plate 701 will gradually open. One side of the soil-breaking plate 701 is cone-shaped, which can quickly break the soil around the body 1.

[0053] When the adjusting wheel 301 is rotated, the rotating shaft 302 will rotate together with the moving part 704. After rotating 180 degrees, the second outlet 405 will be exposed. At this time, the valve of the fertilizer pipeline is opened, and some fertilizer will enter the storage chamber 703 through the second outlet 405, and then enter the soil breaking plate 701 through the flexible connecting pipe 702. After that, it will be discharged into the ground from the third outlet 406, thereby carrying out large-scale irrigation.

[0054] After irrigation is completed, simply close the valve of the fertilizer pipe and manually pull the main body 1 out of the ground. The sliding plate 5 will fall naturally under gravity. At the same time, the user can also manually reset the sliding plate 5 and the unfolding mechanism 7.

[0055] The above structure can solve the technical problems of existing insertion tubes being unable to adjust fertilizer according to the fertilizer requirements of seedlings, and single insertion-type fertilizer devices being unable to adjust their fertilization range, thus resulting in their relatively limited functionality.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
