Description

Technical Field

[0001] This utility model is a soil fertility improvement device, belonging to the field of fertilization technology. Background Technology

[0002] In modern agricultural production, soil fertility is closely related to agriculture and its importance cannot be ignored. Soil fertility directly affects the growth, development, and yield of crops. Poor soil fertility leads to a lack of necessary nutrients for plants, affecting their normal physiological metabolism, and thus reducing farmland yield and crop quality. Improving soil fertility is an important soil management method, which aims to increase soil fertility levels through the application of organic or inorganic fertilizers, crop rotation and fallow, and returning crop straw to the field.

[0003] For example, the existing patent CN214282149U discloses a tea garden soil fertility improvement device. This device compacts organic fertilizers such as cake fertilizer inside the storage rod, and then uses water to carry the substances and microorganisms inside the organic fertilizer into the deep soil layer, which facilitates the absorption of nutrients by the tea tree roots. However, in the existing fertilization, not only one type of fertilizer is applied. When different fertilizers need to be applied, the storage rod cannot be cleaned, which will lead to the mixing of fertilizers and affect the fertilization effect. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a soil fertility improvement device.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A soil fertility improvement device includes a storage cylinder, a tapered rod fixedly connected to the bottom end of the storage cylinder, an inner cylinder slidably connected inside the storage cylinder, a plurality of inner cylinder flow holes evenly formed at the bottom end of the inner cylinder along the circumference, a plurality of storage cylinder flow holes evenly formed at the bottom end of the storage cylinder along the circumference, the inner cylinder flow holes corresponding to the storage cylinder flow holes, a plurality of slots formed on the outer surface of the inner cylinder along the circumference, a plurality of locking blocks evenly fixedly connected to the inner wall of the storage cylinder along the circumference, the locking blocks slidably connected in the locking slots, and a sealing component provided on the inner cylinder to cooperate with the inner cylinder flow holes.

[0018] 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.

[0019] Please see Figure 1-9This utility model provides a soil fertility improvement device, including a storage cylinder 1. A tapered rod 2 is fixedly connected to the bottom end of the storage cylinder 1. An inner cylinder 4 is slidably connected inside the storage cylinder 1. A plurality of inner cylinder flow holes 5 and 6 are evenly opened at the bottom end of the inner cylinder 4 in the circumferential direction. The inner cylinder flow holes 5 and 6 correspond to each other. A plurality of slots 7 are opened on the outer surface of the inner cylinder 4 in the circumferential direction. A plurality of locking blocks 8 are evenly fixedly connected to the inner wall of the storage cylinder 1 in the circumferential direction. The locking blocks 8 are slidably connected in the slots 7. The inner cylinder 4 is provided with a sealing component that cooperates with the inner cylinder flow holes 5. Through the design of the slots 7 and the locking blocks 8, the inner cylinder 4 can be quickly positioned when it is installed, so that the inner cylinder flow holes 5 on the inner cylinder 4 are aligned with the storage cylinder flow holes 6 on the storage cylinder 1 when the inner cylinder 4 is installed, which is convenient for irrigation.

[0020] See Figure 1-9 The sealing assembly includes a plurality of slots 11 evenly spaced on the top of the inner cylinder 4. Each slot 11 corresponds to a flow hole 5 in the inner cylinder. A baffle 10 is slidably connected within each slot 11. The width of the baffle 10 is greater than the diameter of the flow hole 5 in the inner cylinder. The top ends of each baffle 10 extend beyond the inner cylinder 4 and are fixedly connected to a fixing ring 9. A fixing rod 13 is movably connected to one side of the bottom end of the fixing ring 9. A fixing groove 12 is formed on the top of the inner cylinder 4. On the side of the slot 11, the bottom end of the fixing rod 13 abuts against the inner bottom of the fixing groove 12. Through the design of the sealing component, when it is necessary to disassemble the storage cylinder 1 and the inner cylinder 4 to clean the inside of the inner cylinder 4, in order to prevent fertilizer from flowing into the storage cylinder 1 through the inner cylinder flow hole 5 on the inner cylinder 4, the baffle 10 in the sealing component can be driven to block the inner cylinder flow hole 5 before disassembling the inner cylinder, so as to prevent the fertilizer remaining in the inner cylinder 4 from flowing into the storage cylinder 1 through the inner cylinder flow hole 5.

[0021] See Figure 1-9 The storage cylinder 1 is provided with a protective cover 3 on its top. The protective cover 3 has a conical structure. Two ear plates 14 are symmetrically provided on the outer side of the bottom end of the protective cover 3. The ear plates 14 are connected to the storage cylinder 1 by bolts 15. The design of the protective cover 3 can cover the inner cylinder 4 when it rains, preventing rainwater from entering the inner cylinder 4 and melting the organic fertilizer, thus avoiding the phenomenon of over-fertilization.

[0022] See Figure 1-9The top center of the fixing ring 9 is provided with a fixing frame 16, the top of the fixing frame 16 is provided with a placement groove 17, the placement groove 17 is an arc-shaped groove, the middle of the placement groove 17 is provided with a through opening 19, a water pipe 18 is provided in the placement groove 17, and a nozzle is provided at the bottom end of the water pipe 18. The nozzle passes through the through opening 19. The design of the placement groove 17 facilitates the placement of the water pipe 18, and the design of the through opening 19 facilitates the nozzle to pass through the through opening 19.

[0023] See Figure 1-9 The protective cover 3 has a semi-circular groove 21 symmetrically opened at the bottom of both sides. The semi-circular groove 21 matches the outer wall of the water pipe 18. The inner wall of the semi-circular groove 21 is provided with a sealing gasket. The design of the semi-circular groove 21 is that the semi-circular groove 21 matches the outer surface of the water pipe 18. When the water pipe 18 is placed and then the protective cover 3 is installed, the semi-circular groove 21 on the protective cover 3 can fit against the outer wall of the water pipe 18.

[0024] See Figure 1-9 The inner walls of both the fixing ring 9 and the inner cylinder 4 are symmetrically provided with two pull rings 20. The inner wall of the pull ring 20 is provided with an anti-slip rubber ring. The design of the pull ring 20 makes it easy to lift the inner cylinder 4 and the fixing ring 9.

[0025] The circuits, electronic components, controllers, and modules involved are all existing technologies that can be fully implemented by those skilled in the art, so there is no need to elaborate. The content protected by this application does not involve any improvement to the software and methods.

[0026] When using this product, if soil fertility needs to be improved, a 50 cm deep pit needs to be dug in the soil beforehand. Organic fertilizers such as cake fertilizer are placed inside the inner cylinder 4 and compacted. Then, several storage cylinders 1 with a length of about 60 cm are buried in the soil, so that the top of the storage cylinder 1 is about 5 cm above the ground. Then, water pipes 18 are laid and placed on the fixing bracket 16 on the top of the fixing ring 9, so that the nozzle at the bottom of the water pipe 18 passes through the opening 19, so that the water pipe 18 is located in the placement groove 17, and the nozzle is located in the middle of the inner cylinder 4. Then, the protective cover 3 is taken out and moved down towards the fixing ring 9 so that the protective cover 3 is located on the outer surface of the fixing ring 9. At this time, the two semi-circular grooves 21 on the side of the bottom end of the protective cover 3 are exactly matched with the outer surface of the water pipe 18. Then, the protective cover 3 is connected to the storage cylinder 1 by bolts 15. When drip irrigation is not in use, the organic fertilizer ferments and decomposes inside the inner cylinder 4. When drip irrigation is needed, the water pipe 18 is connected to the external water source, so that the water source flows through the water pipe 18 and is sprayed into the inner cylinder 4 through the nozzle. The inner cylinder flow hole 5 and the storage cylinder flow hole 6 are tightly fitted. The water dissolves the organic fertilizer and flows out through the inner cylinder flow hole 5 and the storage cylinder flow hole 6 into the deep soil layer. That is, the water flow can carry the substances and microorganisms inside the organic fertilizer into the deep soil layer, which facilitates the improvement of soil fertility. When it is necessary to change the type of fertilizer, the storage cylinder 1 and inner cylinder 4 can be disassembled, and the inside of the inner cylinder 4 can be cleaned to prevent fertilizer mixing. The operation process is as follows: First, remove the protective cover 3 from the storage cylinder 1 using bolt 15. Then, lift the fixing ring 9 downwards using pull ring 20, so that the fixing ring 9 drives the fixing rod 13 on one side of the bottom to move away from the fixing groove 12 at the top of the inner cylinder 4. Then, rotate the fixing rod 13 so that the diameter of the fixing rod 13 is parallel to that of the fixing ring 9. Next, move the fixing ring 9 downwards, so that the fixing ring 9 drives the baffle 10 downwards. When the baffle 10 moves downwards, it moves into the slot 11 until the bottom of the baffle 10 is inserted into the inner bottom of the slot 11, thereby sealing the inner cylinder flow hole 5. Then, the flow through the inside of the inner cylinder 4... Pulling the inner cylinder 4 upwards with the pull ring 20 allows it to be directly removed from the storage cylinder 1. The inside of the inner cylinder 4 can then be cleaned and replaced with fresh fertilizer. Next, align the slot 7 on the outside of the inner cylinder 4 with the locking block 8 on the inner wall of the storage cylinder 1, and move the inner cylinder 4 downwards. The inner cylinder 4 will slide into the slot 7 via the locking block 8, allowing for quick installation. Then, lift the fixing ring 9 upwards. After lifting it a certain distance, rotate the fixing rod 13 in the opposite direction so that the bottom end of the fixing rod 13 aligns with the fixing groove 12. Then, release the fixing ring 9. Under gravity, the bottom end of the fixing rod 13 will be inserted into the fixing groove 12. At this point, the bottom end of the baffle 10 is above the inner cylinder flow hole 5, preventing obstruction of the flow hole 5 and thus ensuring fertilizer flow.

[0027] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
