Abstract
Description
Technical Field
[0001] This utility model relates to the field of fertilizer spraying technology, specifically a fertilizer spraying device for agricultural planting. Background Technology
[0002] In agricultural planting, the rational application of fertilizers has a crucial impact on crop growth and yield. Fertilizers not only provide crops with the main nutrients such as nitrogen, phosphorus, and potassium, but also supplement micronutrients, promote healthy plant development, and enhance resistance to diseases and pests. With the development of modern agriculture, precision fertilization has become an important means to improve agricultural production efficiency and sustainability.
[0003] Currently, patent CN221710492U discloses a fertilizer mixing and spraying device for fruit and vegetable planting, including a frame, wheels, support legs, and push handles. A bracket is set at the bottom of the frame, and wheels are installed on the bracket. Two sets of support legs are set at the bottom of the frame, and the two sets of support legs and wheels are arranged in a triangle. Two sets of push handles are set at the right end of the frame. It also includes a positioning frame assembly, an electric sprayer assembly, a nozzle assembly, and a second atomizing nozzle assembly. The nozzle assembly is set at the left end of the frame, and the positioning frame assembly is set at the top of the frame. The electric sprayer assembly is placed in the positioning frame assembly, and the second atomizing nozzle assembly is used in conjunction with the electric sprayer assembly.
[0004] However, the above-mentioned device has the following problems when in use: the spraying device has certain limitations. First, the height adjustment range of the spraying platform is limited. For crops such as corn, sorghum, sugarcane, potatoes, and cotton, which require ridge planting and gradually increase in height during the growth cycle, the plant height often exceeds the effective working range of the spraying platform in the middle and later stages of the growth cycle, making it inconvenient to use. Second, the equipment can only spray from the top of the plant and does not have the ability to precisely target and spray the roots and leaves, making it difficult to ensure uniform coverage of pesticides or fertilizers, affecting the effectiveness of fertilization and pest control, and thus reducing the overall spraying efficiency. Utility Model Content
[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a fertilizer spraying device for agricultural planting, which can achieve uniform fertilization at multiple height levels and ensure nutrient supply.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Please see Figures 1 to 4 A fertilizer spraying device for agricultural planting includes a platform 1, on which casters 2 and a push plate 3 are provided. The device can be moved by hand using the push plate 3, which is convenient to use. Preferably, a drive source can be installed on the casters 2 to ensure automatic movement and reduce the degree of manual intervention. The size of the casters 2 can be adjusted according to actual needs to ensure normal movement of the device in the field. No specific limitation is made here.
[0023] The placement platform 1 is equipped with a conveying component, which is responsible for conveying water and fertilizer from the water and fertilizer tank 4 to the atomizing nozzle 12.
[0024] Two connecting plates 8 are fixedly installed on the placement platform 1. Each connecting plate 8 is fixedly installed with a fixing frame 9, and the fixing frame 9 is equipped with an angle adjustment component.
[0025] There should be a passageway in the land for the platform 1 to move, and the distance between adjacent passageways should be the length of two fixed frames 9.
[0026] Rotating frames 10 are rotatably mounted on both fixed frames 9 via shafts 14. The connecting plate 8 and the fixed frames 9 work together to provide a fixed support point for the rotating frames 10, while allowing them to adjust their angle according to the type of crop and growth cycle to adapt to different spraying needs. The highest point of the rotating frames 10 should be higher than the height of the plant so that the plant will not affect the normal movement of the rotating frames 10.
[0027] A surrounding plate 11 is fixedly installed at equal intervals on the rotating frame 10. Atomizing nozzles 12 are provided on the surrounding plate 11. The crop is located in the space between the surrounding plates 11. The surrounding plate 11 corresponds to the position of the ridge or furrow in the land. The atomizing nozzles 12 can spray fertilizer on the crops planted on it.
[0028] The atomizing nozzle 12 adopts a structure similar to the nozzle at the front of the spray bottle. By rotating the block-shaped structure at the front of the nozzle (usually called an adjusting cap or knob), there is an opening inside the adjusting cap that matches the nozzle outlet. The shape of this opening can change according to the rotation position. When the adjusting cap is rotated, different shaped openings will change the liquid flow path, thereby affecting the spraying area. For example, when fully open, it forms a circular opening, providing the maximum spraying area; when partially closed, it forms a slit-like opening, producing a thin fan-shaped spray. Thus, the opening and closing of the atomizing nozzle 12 and the adjustment of the fan-shaped water outlet area can be controlled by rotating the adjusting cap (since this is existing technology and not a distinguishing technical feature, it is not described in detail). Furthermore, the opening and closing of the atomizing nozzle 12 can also be controlled by directly installing a shield at the water outlet end of the atomizing nozzle 12 through threads or other means. This allows for targeted spraying of the plant roots or leaves as needed, making it more convenient to use.
[0029] Both the rotating frame 10 and the surrounding plate 11 are hollow structures, and the rotating frame 10 is connected to the surrounding plate 11. This design allows liquid fertilizer to flow through the rotating frame 10 and into the surrounding plate 11, and then be sprayed out through the atomizing nozzle 12, ensuring the fluidity during the spraying process.
[0030] The cross-section of the surrounding plate 11 is n-shaped. The atomizing nozzles 12 are evenly and equidistantly embedded on the inward-facing surface of the surrounding plate 11. The n-shaped design increases the wrapping effect of the surrounding plate 11 on the plant and provides good positioning for the atomizing nozzles 12, ensuring that they face the plant inside the surrounding plate 11, that is, the area to be sprayed, in order to achieve the best spraying effect. Moreover, the evenly and equidistantly arranged atomizing nozzles 12 can spray fertilizer at different heights on the same plant, ensuring that each part can be fertilized evenly and ensuring the effect of fertilization.
[0031] The conveying assembly includes a water and fertilizer tank 4 and a pump body 5. The water and fertilizer tank 4 and the pump body 5 are installed on the placement platform 1. The water and fertilizer tank 4 and the pump body 5 are connected by a connecting pipe 6. Two corrugated conveying pipes 7 are embedded in the output end of the pump body 5. The two corrugated conveying pipes 7 are fixedly connected to the corresponding rotating frame 10.
[0032] The fertilizer tank 4 stores the fertilizer solution. The pump body 5 draws and pressurizes the fertilizer through the connecting pipe 6, and then transports the fertilizer to the rotating frame 10 through the corrugated conveying pipe 7, finally reaching the atomizing nozzle 12 on the surrounding plate 11.
[0033] The angle adjustment assembly includes a fixed arc plate 13 and a limiting hole 17. The fixed arc plate 13 is installed on the left and right sides of the fixed frame 9. Adjustment holes 15 are evenly spaced on the fixed arc plate 13. The limiting hole 17 is opened at the corresponding position on the rotating frame 10. A plug rod 16 is movably installed on the fixed arc plate 13. The plug rod 16 is adapted to the adjustment hole 15 and the limiting hole 17.
[0034] The angle adjustment component allows users to adjust the spraying angle according to the height of the crop. Inserting the rod 16 into different adjustment holes 15 and limit holes 17 can lock the position of the rotating frame 10, ensuring the accuracy of the spraying angle and preventing fertilizer waste.
[0035] The insertion rod 16 has an external thread, and the limiting hole 17 has an internal thread that matches the insertion rod 16. This thread design ensures that the insertion rod 16 can be tightened in the limiting hole 17, preventing the angle from being unstable due to vibration or other reasons during operation.
[0036] The center of the fixed arc plate 13 and the center of the shaft 14 are on the same straight line, ensuring that the adjustment holes 15 at different positions can be smoothly aligned with the limiting holes 17, thus guaranteeing the docking effect.
[0037] The working process of this utility model is as follows: The operator fills the water and fertilizer tank 4 with fertilizer solution and ensures that the pump body 5, connecting pipe 6 and corrugated conveying pipe 7 are correctly connected and leak-free. If the caster wheel 2 is equipped with a drive source, the operator can start the automatic walking function through the control panel so that the equipment can move to the designated field location autonomously. Otherwise, the device is manually pushed by the push plate 3.
[0038] The operator sets the optimal spraying angle of the rotating frame 10 according to the plant's growth height. By aligning the appropriate adjustment hole 15 with the limiting hole 17, and inserting the rod 16 into the adjustment hole 15 and the limiting hole 17 and rotating it, the position of the rotating frame 10 can be fixed. The rotating frame 10 will not cause damage to the plant after adjustment.
[0039] The pump body 5 starts working when the pump is moved manually or by a drive source. It draws fertilizer solution from the water and fertilizer tank 4 and delivers it to the corrugated delivery pipe 7 after being pressurized through the connecting pipe 6. The fertilizer solution then enters the rotating frame 10 and the surrounding plate 11 and is finally sprayed out evenly by the atomizing nozzle 12. Since the surrounding plate 11 is designed with an n-shaped cross section, it can better wrap the plant, so that the atomizing nozzle 12 can fertilize the same plant at different heights, ensuring that the fertilizer is distributed more evenly.
[0040] After spraying an area, turn off pump 5 to stop fertilizer delivery, and then move the equipment to the next location that needs to be sprayed or return it to the storage point.
[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
