Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, and in particular to an agricultural fertilization device. Background Technology

[0002] Fertilization refers to agricultural techniques that involve applying fertilizer to the soil or spraying it on plants to provide them with the nutrients they need and to maintain and improve soil fertility. The main purpose of fertilization is to increase crop yield, improve crop quality, enrich the soil, and enhance economic benefits. Therefore, rational and scientific fertilization is one of the main means of ensuring food security and maintaining sustainable agricultural development.

[0003] However, traditional agricultural fertilization involves digging holes with hoes and then manually placing fertilizer into the holes. During the fertilization process, workers need to bend over constantly, which greatly increases their workload. Utility Model Content

[0004] The purpose of this invention is to provide an agricultural fertilization device to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an agricultural fertilization device, comprising an annular rubber ring fixedly installed at the bottom of a fertilizer cylinder, two semi-conical insertion tubes fixedly installed at the bottom of the annular rubber ring, an adjusting rod provided inside the fertilizer cylinder, an upper circular plate slidably sleeved on the adjusting rod, two fixed rods fixedly installed on the upper circular plate, and both fixed rods fixedly connected to the fertilizer cylinder, a lower circular plate fixedly sleeved on the two adjusting rods, a compression spring movably sleeved on the adjusting rod, the top end of the compression spring fixedly connected to the upper circular plate, and the bottom end of the compression spring fixedly connected to the lower circular plate, two hinged rods hingedly installed on the adjusting rod, and the bottom ends of the two hinged rods respectively hinged to the two semi-conical insertion tubes, an adjusting plate fixedly installed at the top of the adjusting rod, and both sides of the adjusting plate extending outside the fertilizer cylinder and movably connected to the fertilizer cylinder, two gripping plates fixedly installed on the outer wall of the fertilizer cylinder, and both gripping plates located below the adjusting plate.

[0006] Preferably, a protective telescopic corrugated tube is movably sleeved on the compression spring, and the bottom end of the protective telescopic corrugated tube is fixedly connected to the lower circular plate, and the top end of the protective telescopic corrugated tube is fixedly connected to the upper circular plate.

[0007] Preferably, a funnel is fixedly installed inside the fertilizer cylinder, and the adjusting rod passes through the funnel and is movably connected to the funnel. Two horizontal plates are fixedly installed on the funnel, and elastic pull ropes are fixedly installed at the bottom of the two horizontal plates. An annular sealing plate is movably sleeved on the adjusting rod, and the annular sealing plate is fixedly connected to the bottom end of the two elastic pull ropes.

[0008] Preferably, the fertilizer cylinder has two openings on its outer wall, and the adjusting plate passes through the two openings and is slidably connected to the inner walls of the two openings.

[0009] Preferably, the upper circular plate has a through hole, a linear bearing is fixedly installed in the through hole, and the adjusting rod passes through the linear bearing and is slidably connected to the inner wall of the linear bearing.

[0010] Preferably, the two grippers are provided with a plurality of friction stripes.

[0011] The beneficial effects of this utility model are as follows:

[0012] In this invention, fertilizer is first poured into a funnel. Under the weight of the fertilizer, the annular sealing plate moves downward, opening the funnel and allowing the fertilizer to fall into the fertilizer cylinder. Once the fertilizer has fallen into the cylinder, the elastic rope returns to its original shape, pulling the annular sealing plate upward to block the funnel, preventing fertilizer leakage from the fertilizer cylinder when the device is laid horizontally. The worker holds two gripping plates and inserts the semi-conical tubes into the soil. Then, the worker presses the adjusting plate and moves it downward, pushing the two semi-conical tubes away from each other to open the fertilizer cylinder, allowing the fertilizer to slide into the soil. When the amount of fertilizer in the soil reaches the appropriate level, the adjusting plate is released, the compressed spring returns to its original shape, and the two semi-conical tubes are pulled closer together to reassemble into a complete conical tube, blocking the fertilizer cylinder and stopping the addition of fertilizer to the soil. Repeating the above operation allows fertilization to be completed without bending over, making the process simple, fast, and highly efficient. Attached Figure Description

[0019] 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.

[0020] This utility model provides, for example Figure 1-5 An agricultural fertilization device is shown, comprising an annular rubber ring 3 fixedly installed at the bottom of a fertilizer cylinder 1, two semi-conical tubes 4 fixedly installed at the bottom of the annular rubber ring 3, an adjusting rod 2 inside the fertilizer cylinder 1, an upper circular plate 9 slidably sleeved on the adjusting rod 2, and a through hole on the upper circular plate 9 to reduce the friction between the adjusting rod 2 and the upper circular plate 9, thereby reducing the wear of the adjusting rod 2 and improving its service life, a linear bearing is fixedly installed in the through hole, the adjusting rod 2 passes through the linear bearing and is slidably connected to the inner wall of the linear bearing, two fixing rods 10 are fixedly installed on the upper circular plate 9, and both fixing rods 10 are fixedly connected to the fertilizer cylinder 1, a lower circular plate 6 is fixedly sleeved on the two adjusting rods 2, and a compression spring 8 is movably sleeved on the adjusting rod 2, with the top end of the compression spring 8 connected to the lower circular plate 6. The upper circular plate 9 is fixedly connected, and the bottom end of the compression spring 8 is fixedly connected to the lower circular plate 6. Two hinge rods 5 are hinged on the adjusting rod 2, and the bottom ends of the two hinge rods 5 are respectively hinged to the two semi-conical insertion tubes 4. An adjusting plate 11 is fixedly installed at the top of the adjusting rod 2, and both sides of the adjusting plate 11 extend outside the fertilizer cylinder 1. In order to facilitate the adjustment plate 11 to move out of the fertilizer cylinder 1, two openings are opened on the outer wall of the fertilizer cylinder 1. The adjusting plate 11 passes through the two openings and slides with the inner wall of the two openings, and is movably connected with the fertilizer cylinder 1. Two gripping plates 12 are fixedly installed on the outer wall of the fertilizer cylinder 1. In order to prevent people from slipping when holding the gripping plates 12 and affecting work efficiency, several friction stripes are opened on the two gripping plates 12, and both gripping plates 12 are located below the adjusting plate 11.

[0021] In order to protect the compression spring 8 and prevent fertilizer from directly contacting the compression spring 8 and affecting its service life, a protective telescopic corrugated tube 7 is movably sleeved on the compression spring 8. The bottom end of the protective telescopic corrugated tube 7 is fixedly connected to the lower circular plate 6, and the top end of the protective telescopic corrugated tube 7 is fixedly connected to the upper circular plate 9.

[0022] To prevent fertilizer from leaking out of the fertilizer cylinder 1 when the device is laid horizontally, thus avoiding fertilizer waste, a funnel 13 is fixedly installed inside the fertilizer cylinder 1, and an adjusting rod 2 passes through the funnel 13 and is movably connected to the funnel 13. Two horizontal plates 17 are fixedly installed on the funnel 13, and elastic pull ropes 16 are fixedly installed at the bottom of the two horizontal plates 17. An annular sealing plate 15 is movably sleeved on the adjusting rod 2, and the annular sealing plate 15 is fixedly connected to the bottom end of the two elastic pull ropes 16.

[0023] The working principle of the agricultural fertilization device provided by this utility model is as follows: In the initial state, both the compression spring 8 and the elastic rope 16 are in a stretched state. The compression spring 8 causes the two semi-conical tubes 4 to fit tightly together to form a complete conical tube. When the device is needed, the fertilizer is first poured into the funnel 13. Under the action of the fertilizer's gravity, the annular sealing plate 15 moves downward and separates from the funnel 13, opening the funnel 13 and allowing the fertilizer to fall into the fertilizer cylinder 1. When the fertilizer has fallen into the fertilizer cylinder 1, the elastic rope 16 returns to its original shape, pulling the annular sealing plate 15 upward to contact the funnel 13, thus blocking the funnel 13. This ensures that the fertilizer is always in a relatively sealed environment, preventing fertilizer from leaking out of the fertilizer cylinder 1 when the device is laid horizontally, thus preventing fertilizer waste. When it is necessary to add fertilizer... During fertilization, the worker holds two gripping plates 12 with both hands, inserts the semi-conical tube 4 into the soil, and then presses the adjusting plate 11 downwards, causing the adjusting rod 2 to move downwards. The adjusting rod 2 moves downwards, causing the hinge rod 5 to move downwards. The hinge rod 5 moves downwards, pushing the two semi-conical tubes 4 away from each other, opening the fertilizer cylinder 1 and allowing fertilizer to slide from the fertilizer cylinder 1 into the soil. When the amount of fertilizer entering the soil is appropriate, the adjusting plate 11 is released, the compressed spring 8 returns to its original shape, and the lower circular plate 6, adjusting rod 2, and hinge rod 5 are pulled upwards, causing the two semi-conical tubes 4 to move closer together and reassemble into a complete conical tube, blocking the fertilizer cylinder 1 and stopping the addition of fertilizer to the soil. By repeating the above operation, the fertilization work can be completed without bending over. The process is simple, fast, and efficient.

[0024] Compared with related technologies, the agricultural fertilization device provided by this utility model has the following beneficial effects:

[0025] This utility model provides an agricultural fertilization device. First, fertilizer is poured into the funnel 13. Under the weight of the fertilizer, the annular sealing plate 15 moves downward, opening the funnel 13 and allowing the fertilizer to fall into the fertilizer cylinder 1. Once the fertilizer has fallen into the fertilizer cylinder 1, the elastic rope 16 returns to its original shape, pulling the annular sealing plate 15 upward to block the funnel 13, preventing fertilizer leakage from the fertilizer cylinder 1 when the device is laid horizontally. The worker then inserts the semi-conical tube 4 into the soil by holding the two gripping plates 12. The worker presses and moves the adjusting plate 11 downwards, pushing the two semi-conical tubes 4 away from each other to open the fertilizer cylinder 1, allowing fertilizer to slide from the fertilizer cylinder 1 into the soil. When the amount of fertilizer entering the soil reaches the appropriate level, the adjusting plate 11 is released, the compressed spring 8 returns to its original shape, and the two semi-conical tubes 4 are pulled closer together to reassemble into a complete conical tube, blocking the fertilizer cylinder 1 and stopping the addition of fertilizer to the soil. By repeating the above operation, the fertilization work can be completed without bending over. The process is simple, fast, and efficient.
