Abstract
Description
Technical Field
[0001] This utility model is a forestry seedling fertilization device, belonging to the field of forestry seedling technology. Background Technology
[0002] Fertilization is a crucial step in cultivating high-quality seedlings. Proper fertilization provides sufficient nutrients for seedling growth, promoting healthy development and improving seedling quality and survival rate. Topdressing is applied according to the needs of different growth stages of the seedlings. In practical forestry seedling cultivation, considering the efficient use of land resources and the space requirements of early-stage seedling growth, relatively small seedling spacing is usually set during cultivation. In the early stages, this spacing has no obvious drawbacks; on the contrary, it helps to concentrate land use and increase seedling yield per unit area. As time progresses, the seedlings begin to grow rapidly.
[0003] As the seedlings grow to a certain stage, problems gradually emerge. The branches and leaves of adjacent seedlings extend and expand, inevitably obstructing each other. The originally independent growth space becomes crowded, with branches and leaves intertwining and overlapping. This situation significantly hinders the application of fertilizer to the seedling roots. During fertilization, whether applied manually or using mechanical equipment, the fertilizer is easily blocked by the intertwined branches and leaves. A large amount of fertilizer thus falls onto the branches and leaves, rather than the intended soil around the roots. This fertilizer accumulation on the branches and leaves causes a series of problems. On the one hand, the chemicals in the fertilizer may burn the leaves, affecting photosynthesis and hindering normal growth and development. On the other hand, the fertilizer cannot be effectively absorbed by the roots, resulting in waste and increasing seedling costs. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a forestry seedling fertilization device to solve the problems mentioned in the background technology. This utility model reduces the amount of fertilizer falling on branches and leaves, avoids leaf burn, and improves fertilizer utilization.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a forestry seedling fertilization device, comprising a straight pipe, a fan-shaped pipe head installed at the lower end of the straight pipe, the end of the fan-shaped pipe head away from the straight pipe being arc-shaped, a funnel cover installed at the upper end of the straight pipe, the inner radial direction of the funnel cover gradually increasing away from the straight pipe, a handle installed on the outer surface of the end of the straight pipe near the funnel cover, and a transparent cover connected to the straight pipe by a connector, the transparent cover having a conical structure, the inner radial direction of the transparent cover gradually increasing near the end of the funnel cover.
[0006] Furthermore, the connector includes a sleeve, on which the sleeve is installed at the end of the transparent cover facing the fan-shaped tube head. The sleeve is fitted onto the straight tube, and the inner diameter of the sleeve is the same as the outer diameter of the straight tube. The outer surface of the sleeve is threaded with a positioning screw for limiting the relative position of the sleeve and the straight tube.
[0007] Furthermore, the outer surface of the sleeve is provided with a shaft hole, which is arranged along the radial direction of the sleeve. A threaded sleeve is provided on the outside of the shaft hole, which is concentrically arranged with the shaft hole. One end of the threaded sleeve is connected and fixed to the sleeve. The positioning screw is threadedly connected inside the threaded sleeve, and one end of the positioning screw passes through the shaft hole and contacts the straight pipe.
[0008] Furthermore, a connecting tube is fitted onto the upper end of the straight tube and is bonded to the straight tube with glue, and the outer surface of the connecting tube is installed on both ends of the handle.
[0009] Furthermore, a filter disc is provided inside the funnel hood on the side near the straight tube. A connecting rod is installed in the middle of the side of the filter disc facing the straight tube. A rubber sleeve is fitted on the end of the connecting rod away from the filter disc. Multiple connecting parts are installed in a ring at equal intervals between the rubber sleeve and the connecting rod. The rubber sleeve is in contact with the inner wall of the straight tube.
[0010] Furthermore, the outer surface of the connecting rod near the filter disc is machined with external threads, and a straight threaded cylinder is threadedly connected to the threaded end of the connecting rod, and the straight threaded cylinder is fixedly connected to the filter disc.
[0011] Furthermore, the connecting part and the rubber sleeve are integrally formed, and the side of the connecting part facing the filter disc is an inclined surface.
[0012] The beneficial effects of this utility model are:
[0013] 1. The fan-shaped tube head at the lower end of the straight tube and the conical transparent cover fitted on the straight tube work together. The arc-shaped design of the fan-shaped tube head makes it easy to reach into the gaps between seedlings, guiding fertilizer along the straight tube and the fan-shaped tube head to fall into the soil at the root of the seedling, reducing the amount of fertilizer falling on the branches and leaves, avoiding leaf burn, improving fertilizer utilization, and reducing seedling costs.
[0014] 2. When the straight pipe is inserted into the gaps between the seedlings, the transparent cover will compress the branches and leaves of the seedlings. This allows the fertilizer applicator to observe the relative position between the fan-shaped pipe head and the seedling roots through the transparent cover, avoiding blind fertilization and preventing the fertilizer from being too close to the seedling roots. The relative position of the transparent cover and the straight pipe can be adjusted, and the positioning screws can be used to limit the relative position of the transparent cover and the straight pipe, so that the position of the transparent cover can be adjusted according to the height of the seedlings.
[0015] 3. Place the filter disc inside the funnel cover and insert the rubber sleeve into the straight tube. At this time, the rubber sleeve is in close contact with the inner wall of the straight tube. Under the action of the friction between the rubber sleeve and the straight tube, it plays a role in restricting the relative position of the filter disc and the funnel cover, preventing the filter disc from moving around randomly. Under the filtration of the filter disc, large particles of fertilizer are prevented from entering the fan-shaped tube head and causing blockage. Attached Figure Description

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0023] Please see Figures 1-3This utility model provides a technical solution: a forestry seedling fertilization device, including a straight pipe 1, a fan-shaped pipe head 7 installed at the lower end of the straight pipe 1, the end of the fan-shaped pipe head 7 away from the straight pipe 1 being arc-shaped, and a funnel cover 5 installed at the upper end of the straight pipe 1, the inner radial direction of the funnel cover 5 gradually increasing away from the straight pipe 1. The fan-shaped pipe head 7 at the lower end of the straight pipe 1 and the conical transparent cover 3 fitted on the straight pipe 1 complement each other. This collaborative working method greatly reduces the probability of fertilizer falling onto the branches and leaves of the seedlings. Fertilizer no longer adheres to the leaves in large quantities, avoiding the chemical substances in the fertilizer from burning the leaves, thereby ensuring that the leaves can carry out photosynthesis normally and maintain the healthy growth of the seedlings. Moreover, because the fertilizer can accurately reach the roots of the seedlings and be fully absorbed by the root system, the utilization rate of fertilizer is significantly improved. While ensuring the nutrients required for seedling growth, fertilizer waste is reduced, thereby reducing the cost of seedling cultivation.
[0024] See Figures 1-3 A handle 10 is installed on the outer surface of one end of the straight tube 1 near the funnel cover 5. That is, a connecting tube 4 is sleeved on the upper end of the straight tube 1 and is glued to the straight tube 1. The outer surface of the connecting tube 4 is installed on both ends of the handle 10. The connecting tube 4 serves to connect the straight tube 1 and the handle 10. The handle 10 provides a carrier for gripping the straight tube 1.
[0025] See Figures 1-3A transparent cover 3 is fitted onto the straight pipe 1. The transparent cover 3 has a conical structure, and its inner radial direction gradually increases towards the end of the funnel-shaped cover 5. A sleeve 2 is installed on the end of the transparent cover 3 facing the fan-shaped pipe head 7. The sleeve 2 is fitted onto the straight pipe 1, and the inner diameter of the sleeve 2 is the same as the outer diameter of the straight pipe 1. A positioning screw 9 for limiting the relative position between the sleeve 2 and the straight pipe 1 is threaded onto the outer surface of the sleeve 2. A shaft hole is opened on the outer surface of the sleeve 2, and the shaft hole is arranged along the radial direction of the sleeve 2. A threaded sleeve 8 is arranged concentrically with the shaft hole on the outside of the shaft hole. One end of the threaded sleeve 8 is connected and fixed to the sleeve 2. The positioning screw 9 is threaded into the threaded sleeve 8, and one end of the positioning screw 9 passes through the shaft hole and contacts the straight pipe 1. The threaded sleeve 8 realizes the stable connection between the positioning screw 9 and the sleeve 2. When using this forestry seedling fertilization equipment, when the straight pipe 1 is slowly inserted into the gap between the seedlings, the transparent cover 3 fitted onto the straight pipe 1 will inevitably come into contact with the branches and leaves of the seedlings and cause some compression. This process is not without its benefits. Through the transparent cover 3, the fertilizer applicator can clearly observe the relative position between the fan-shaped tube head 7 and the seedling roots. This design advantage greatly avoids blind fertilization and effectively prevents damage to the seedling roots caused by fertilizer being too close to them due to inaccurate positioning. In actual operation, if the position of the transparent cover 3 is found to be unsuitable, the fertilizer applicator can flexibly adjust the relative position of the transparent cover 3 and the straight tube 1 based on observation. The positioning screw 9 on the equipment plays an important role at this time. After adjusting the position, tightening the positioning screw 9 can limit the relative position of the transparent cover 3 and the straight tube 1, keeping them fixed.
[0026] See Figures 1-4A filter disc 6 is located inside the funnel cover 5, near the straight tube 1. A connecting rod 11 is installed at the center of the side of the filter disc 6 facing the straight tube 1. The outer surface of the end of the connecting rod 11 near the filter disc 6 is machined with external threads. A straight threaded cylinder 13 is threaded to the threaded end of the connecting rod 11, and the straight threaded cylinder 13 is fixedly connected to the filter disc 6. A rubber sleeve 12 is fitted onto the end of the connecting rod 11 away from the filter disc 6. Multiple connecting parts 14 are installed in a ring at equal intervals between the rubber sleeve 12 and the connecting rod 11. The rubber sleeve 12 fits against the inner wall of the straight tube 1. The connecting parts 14 and the rubber sleeve 12 are integrally formed. The side of the connecting part 14 facing the filter disc 6 is inclined. During installation, the rubber sleeve 12 connected to the filter disc 6 is inserted into the straight tube 1, making it fit tightly against the inner wall of the straight tube 1. The friction generated between the rubber sleeve 12 and the inner wall of the straight tube 1 effectively limits the relative position of the filter disc 6 and the funnel cover 5, ensuring that the filter disc 6 will not move around randomly inside the funnel cover 5. During fertilization, fertilizer enters through the funnel hood 5. At this time, the filter disc 6 plays a crucial role in filtering the fertilizer. It effectively blocks large fertilizer particles, preventing them from entering the fan-shaped tube head 7 and thus avoiding blockages caused by large fertilizer particles. This ensures the smooth operation of the fertilization equipment and the efficient implementation of fertilization work.
