Description

Technical Field

[0001] This utility model relates to the field of fertilizer application, and more specifically, to a fertilizer spreader for hybrid rice seedbeds. Background Technology

[0002] The seedling stage of hybrid rice requires extremely precise nutrient supply. The uniformity and concentration of fertilizer applied to the seedbed directly affect the survival rate and growth quality of the seedlings. Currently, fertilization of hybrid rice seedbeds mainly relies on manual spreading or traditional single-function fertilizer spreaders. Manual spreading is not only labor-intensive and inefficient, but also makes it difficult to control the amount of fertilizer used, easily leading to problems of excessive or insufficient fertilization in certain areas, resulting in uneven seedling growth. Traditional fertilizer spreaders mostly only have a single fertilization function and lack supporting auxiliary control structures. After the fertilizer is discharged from the outlet, it is easy for it to accumulate due to gravity, resulting in excessively high concentrations of fertilizer in certain areas.

[0003] Meanwhile, excessively high fertilizer concentrations can disrupt the soil osmotic pressure around seedling roots, causing root dehydration and shrinkage, leading to seedling burn and death, severely impacting seedling cultivation effectiveness. Furthermore, some fertilizer granules are prone to clumping; clumped fertilizer is difficult to dissolve, not only failing to be absorbed and utilized by seedlings but also creating high-concentration areas in the soil that continuously harm seedling growth.

Detailed Implementation

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0021] like Figures 1-4 As shown, the present invention provides a fertilizer spreader for hybrid rice seedbeds, including a walking support 1, a fertilizer spreading device and a spraying device mounted on the walking support 1; the fertilizer spreading device includes a spreader 2 and a discharge port mounted at the bottom of the spreader 2, a discharge plate 3 detachably mounted on the discharge port, and a guide plate 6 corresponding to and inclined to the discharge plate 3; the spraying device is located at the position after the guide plate 6.

[0022] In the above scheme, when the entire device moves via the walking support 1, the fertilizer spreading device first completes the fertilizer spreading, and the guide plate 6 guides and disperses the discharged fertilizer. Subsequently, the spraying device follows along the same working path. This enables continuous and coordinated operation of fertilization and spraying, eliminating the need for a separate watering process, shortening the operation time, and ensuring precise mixing of water mist and fertilizer. This prevents fertilizer from accumulating after spreading or sticking to the seedling leaves, which could cause seedling burn.

[0023] like Figures 2-3 As shown, the spreader 2 is equipped with a stirring component inside, and a rotary drive assembly is connected to the stirring component. The stirring component rotates at a constant speed inside the spreader 2, so that the fertilizer in the spreader 2 is evenly distributed from the discharge port to the guide plate 6.

[0024] The rotary drive component drives the mixing element to rotate continuously and at a constant speed, stirring and breaking up the fertilizer in the spreader 2, breaking up any clumps, and then evenly pushing the loose fertilizer to the outlet, where it finally falls onto the guide plate 6. This prevents clumps from affecting the uniformity of the discharge, ensuring that the fertilizer falls in a loose state, laying the foundation for subsequent concentration control. At the same time, the constant speed rotation design ensures stable fertilizer application and avoids excessive fertilization in certain areas.

[0025] The spreader 2 is cylindrical, and the length of the discharge port is adapted to the length of the spreader 2. The cylindrical spreader 2 forms a uniform containing space inside, and the fertilizer can be evenly distributed along the length direction during the mixing process. The length of the discharge port is adapted to the length of the spreader 2, so that the fertilizer can be fully covered along the width of the seedbed.

[0026] The discharge plate 3 has a plurality of discharge holes 4 evenly distributed on it, and mounting seats 5 are provided on both sides of the discharge plate 3. The mounting seats 5 are fixed to the spreader 2 by screws. After being stirred by the mixing component, the fertilizer falls quantitatively through the evenly distributed discharge holes 4 on the discharge plate 3. The discharge plate 3 can be disassembled and replaced by the mounting seats 5 and screws. Different diameter discharge holes 4 can be selected according to the fertilization needs. At the same time, the discharge plate 3 can be disassembled for cleaning.

[0027] A limiting plate 7 is provided on the outer periphery of the guide plate 6, and a plurality of guide strips 8 are spaced apart on the guide plate 6, forming a guide groove between adjacent guide strips 8. After the fertilizer falls from the outlet onto the guide plate 6, it slides evenly along the guide groove under the separation effect of the guide strips 8, and the limiting plate 7 prevents the fertilizer from falling off from both sides of the guide plate 6.

[0028] The mixing component includes a mixing shaft 9, a plurality of mixing side plates 10 spaced apart on the mixing shaft 9, and a mixing end plate 11 located at the end of the mixing side plates 10 and connected to the plurality of mixing side plates 10. The mixing end plate 11 is disposed close to the inner wall of the spreader 2.

[0029] In the above scheme, the stirring shaft 9 drives the stirring side plate 10 and the stirring end plate 11 to rotate synchronously. The stirring side plate 10 stirs the fertilizer laterally, and the stirring end plate 11 rotates close to the inner wall of the spreader 2 to scrape off the fertilizer attached to the inner wall and avoid residue.

[0030] The rotary drive assembly includes a drive motor 12, a drive wheel 13 connected to the output end of the drive motor 12, a driven wheel 14 cooperating with the drive wheel 13, and a belt structure 15. The stirring shaft 9 is fixedly connected to the shaft of the driven wheel 14. After the drive motor 12 starts, power is transmitted to the stirring shaft 9 through the transmission cooperation of the drive wheel 13, the belt structure 15, and the driven wheel 14, causing the stirring shaft 9 to rotate at a uniform speed.

[0031] The spraying device includes a water storage tank 16, a diversion pipe 17 installed on the water storage tank 16, a sprayer 18 connected to the diversion pipe 17, and a plurality of spray heads 19 installed on the sprayer 18. The spreader 2 spreads fertilizer while the spray heads 19 spray water mist.

[0032] In the above scheme, water in the water storage tank 16 is transported to the sprayer 18 through the diversion pipe 17. After being atomized by several spray heads 19, it forms a uniform water mist, which is sprayed onto the seedbed simultaneously with fertilizer application. The water mist fully contacts the fertilizer particles and penetrates into the soil surface. The water mist dilutes the fertilizer, effectively reducing the local fertilizer concentration and avoiding problems such as burning or killing seedlings. At the same time, the atomization design ensures uniform water distribution, both regulating the concentration and providing suitable humidity for the seedlings, promoting fertilizer dissolution and absorption, and improving fertilization efficiency.

[0033] This solution addresses the problem of excessively high fertilizer concentrations that often occur with traditional fertilization methods through the coordinated design of a fertilizer spreading device and a spraying device. The mixing component and uniform discharge structure ensure that the fertilizer is loose and falls in a measured amount, while the guide plate 6 further guarantees even distribution. Simultaneously, the water mist spraying from the spraying device dilutes the localized fertilizer concentration, preventing seedling burn and death. The entire system allows for simultaneous fertilization and moisture retention, reducing labor intensity, increasing efficiency, promoting fertilizer dissolution and absorption, and ensuring the healthy growth of hybrid rice seedlings.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
