Description

Technical Field

[0001] This utility model relates to a fertilization device for a no-till seeder, belonging to the technical field of no-till seeders. Background Technology

[0002] No-till seeding refers to the process of completing all steps, including ditching, fertilizing, sowing, covering, and compacting, in a field with the residue of the previous crop (such as straw and stubble) without any tillage or preparation.

[0003] Traditional no-till planters' fertilizer applicators (especially for powdery or hygroscopic fertilizers) are usually passive or rely on gravity to fall naturally. During the transport process, they are prone to forming bridging at bends and narrow passages. This phenomenon is often called fertilizer bridging, which affects work efficiency.

[0004] Furthermore, the fertilization devices of traditional no-till planters typically only support one fertilization method: either strip application or spreading. Switching between these methods may require replacing the entire fertilization unit, which is complex.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a fertilization device for no-till seeders, which ensures the continuity and stability of the fertilization process and allows for quick switching of fertilization modes, thereby enhancing the flexibility and adaptability of fertilization operations.

[0007] To solve the above technical problems, the present invention adopts the following technical solution: A fertilizer applicator for a no-till planter includes a dispersing cylinder, which is fixed to the bottom end of a vertically positioned fixed pipe. The fixed pipe has an inclined inlet pipe on its side, and an inclined outlet pipe is fixedly installed at the bottom of the dispersing cylinder. Both the inlet pipe and the outlet pipe are connected to the dispersing cylinder. A motor is fixedly installed in the lower part of the inner cavity of the fixed pipe, and an eccentric shaft is installed on the output shaft of the motor. The eccentric shaft is located inside the dispersing cylinder. An outlet auxiliary pipe connected to the outlet pipe is installed at the end of the outlet pipe away from the dispersing cylinder. The outlet auxiliary pipe has a detachable structure.

[0008] Furthermore, the centerline of the dispersion cylinder is set in the horizontal direction.

[0009] Furthermore, a lug is fixedly connected to the top side of the fixed tube, and the lug is fixed to the tail of the no-till planter frame.

[0010] Furthermore, a battery and a flip cover are sequentially installed in the upper part of the inner cavity of the fixed tube. The battery adopts a detachable structure and provides power to the motor.

[0011] Furthermore, the end of the drug inlet tube away from the dispersion cylinder is provided with a connector.

[0012] Furthermore, the connector is used to insert and fix the bottom end of the drainage tube, and the top end of the drainage tube is connected to the pesticide storage shell on the no-till planter frame.

[0013] Furthermore, a reinforcing plate is installed between the drug inlet tube and the fixing tube.

[0014] Furthermore, the auxiliary dispensing pipe and the main dispensing pipe are connected by a snap-fit ​​mechanism.

[0015] Furthermore, the dispensing auxiliary pipe has a tapered section at the end near the dispensing main pipe.

[0016] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages: By installing an eccentric shaft driven by a motor inside the dispersing cylinder, the eccentric shaft mechanically impacts and agitates the falling fertilizer, effectively breaking up the initially formed clumps and actively throwing them out. This fundamentally avoids the clogging problem caused by poor physical properties of the fertilizer, ensuring the continuity and stability of the fertilization process.

[0017] The modular outlet design allows for a scattering fertilization mode when the auxiliary dispensing pipe is not installed. The fertilizer is freely discharged from the large-diameter main dispensing pipe and naturally dispersed under the action of gravity, inertia, and centrifugal force. When the auxiliary dispensing pipe is installed, a strip application mode is used. The tapering section gathers and constrains the dispersed fertilizer flow, forming a concentrated fertilizer bundle that is precisely applied to the seed row. The fertilization mode can be quickly switched according to different crops and agronomic requirements, enhancing operational flexibility and adaptability.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0022] like Figure 1 and Figure 2 As shown in the figure, this utility model provides a fertilizer application device for a no-till seeder, including a dispersing cylinder 1. The center line of the dispersing cylinder 1 is set in the horizontal direction. The dispersing cylinder 1 is fixed to the bottom end of a fixed pipe 2 set in the vertical direction. The top side of the fixed pipe 2 is provided with an ear plate 11 fixedly connected to it. The ear plate 11 is fixed to the tail of the no-till seeder frame. The side of the fixed pipe 2 has an inclined inlet pipe 3. The bottom of the dispersing cylinder 1 is fixedly installed with an inclined outlet pipe 5. Both the inlet pipe 3 and the outlet pipe 5 are connected to the dispersing cylinder 1.

[0023] A motor 8 is fixedly installed in the lower part of the inner cavity of the fixed tube 2. An eccentric shaft 7 is installed on the output shaft of the motor 8, and the eccentric shaft 7 is located inside the dispersion cylinder 1. The motor 8 drives the eccentric shaft 7 to rotate at high speed, so as to evenly distribute the agent entering the dispersion cylinder 1. The agent is then dispersed through the main discharge pipe 5.

[0024] The upper part of the inner cavity of the fixed tube 2 is equipped with a storage battery 9 and a flip cover 10. The storage battery 9 adopts a detachable structure and provides power to the motor 8. The storage battery 9 is installed through the flip cover 10.

[0025] The end of the inlet tube 3 away from the dispersing cylinder 1 is provided with a connector 12. The connector 12 is used to insert and fix the bottom end of the drainage tube 4. The top end of the drainage tube 4 is connected to the storage shell on the frame of the no-till planter.

[0026] A reinforcing plate 15 is installed between the drug inlet tube 3 and the fixed tube 2 to enhance the connection strength between the drug inlet tube 3 and the fixed tube 2.

[0027] A secondary dispensing pipe 6 is installed at the end of the main dispensing pipe 5 furthest from the dispersing cylinder 1, and is connected to it. The secondary dispensing pipe 6 is used for strip application. The secondary dispensing pipe 6 is connected to the main dispensing pipe 5 by a snap-fit ​​14. The end of the secondary dispensing pipe 6 near the main dispensing pipe 5 has a tapered section 13. The secondary dispensing pipe 6 has a detachable structure, which facilitates selective installation according to fertilization needs.

[0028] The specific working principle of this utility model is as follows: Fertilizer flows from the storage tank on the no-till planter frame, passes through the diversion pipe 4 and the inclined inlet pipe 3, and falls into the dispersion cylinder 1. The motor 8 drives the eccentric shaft 7 to rotate at high speed. The eccentric shaft 7 generates uneven centrifugal force during rotation, which disperses and mixes the fertilizer and pushes it axially, ensuring that the fertilizer flows evenly to the main discharge pipe 5. After the fertilizer reaches the main discharge pipe 5, depending on the different installed components, it can be applied in two modes: broadcasting and strip application.

[0029] Fertilizer spreading: Without installing the auxiliary discharge pipe 6, the fertilizer, after being stirred by the eccentric shaft, directly enters the downward-sloping main discharge pipe 5. Since the opening of the main discharge pipe 5 is relatively large and unrestrained, the fertilizer is discharged in a relatively dispersed stream under the combined action of gravity, its own inertia, and the pushing force of the eccentric shaft 7. When the fertilizer stream hits the air and the ground, it will naturally disperse, forming a relatively wide fertilization zone, thereby achieving the effect of spreading.

[0030] Stream fertilization: A secondary fertilizer outlet pipe 6 is installed. After the fertilizer flows out of the main fertilizer outlet pipe 5, it immediately enters the secondary fertilizer outlet pipe 6. The inlet end of the secondary fertilizer outlet pipe 6 is designed with a tapering section 13, which concentrates the dispersed fertilizer and, under the constraint of the subsequent pipeline, forms a concentrated, compact, linear fertilizer stream. The fertilizer stream is precisely delivered to a specific location in the seedbed, achieving precise strip application.

[0031] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
