Description

Technical Field

[0001] The invention relates to the technical field of agricultural mechanization, in particular to a variable-width fertilizer spreader. Background Art

[0002] As an important part of agricultural mechanization, fertilizer spreaders are widely used in farmland fertilization operations. Traditional fertilizer spreaders usually use rotation or throwing methods to evenly distribute fertilizers in the field to improve fertilizer utilization efficiency and promote crop growth. With the continuous development of agricultural production methods, the design and technology of fertilizer spreaders have also undergone significant evolution;

[0003] Early fertilizer spreaders were mostly manually operated, which was inefficient and labor-intensive. With the advancement of mechanization, various types of fertilizer spreaders have emerged, such as centrifugal fertilizer spreaders and pneumatic fertilizer spreaders. These mechanized equipment not only improves the efficiency of fertilization, but also achieves significant improvements in the uniform distribution and application accuracy of fertilizers.

[0004] In recent years, the rise of smart agricultural technology has promoted the further development of fertilizer spreaders. Modern fertilizer spreaders have gradually introduced automated control systems and precision fertilization technology. Through sensors and data analysis, dynamic adjustment of fertilizer application amount and width can be achieved. This intelligent fertilizer spreader can accurately apply fertilizer according to the crop growth stage and soil conditions, thereby improving crop yield and quality.

[0005] However, although the current fertilizer spreaders have made significant progress in efficiency and intelligence, they still face some technical challenges. First, in traditional fertilization operations, the fertilization equipment is usually heavy, and it is difficult to control the movement and stability of the equipment during the operation, resulting in excessive soil compaction. Soil compaction not only affects the growth and development of the root system, but also hinders the penetration of water and air, reducing the permeability and fertility of the soil. This problem is common in agricultural production and seriously affects the healthy growth and yield of crops. Therefore, how to reduce the pressure of fertilization equipment on the soil has become a technical problem that needs to be solved urgently;

[0006] Secondly, traditional fertilizer spreaders often lack flexibility in fertilizer width and are difficult to adjust according to the needs of different crops and fields. This results in uneven fertilizer coverage during fertilization, resulting in fertilizer waste or shortage, affecting crop growth. At the same time, overly long pipes are prone to interference during fertilization, resulting in unsmooth operation, increasing equipment loss and maintenance costs. Therefore, how to design a fertilizer spreading system that can flexibly adjust the fertilizer spreading width and ensure equipment stability has become an important direction for technical improvement.

[0007] Finally, during the fertilization process, the stirring and uniformity of the fertilizer are the key to ensuring the fertilization effect. However, the stirring design of traditional equipment often cannot effectively prevent the fertilizer from adhering to the inner wall, resulting in fertilizer sedimentation and agglomeration, affecting subsequent transportation and application. In addition, the agglomerated fertilizer that sinks to the bottom often cannot be effectively re-transported and mixed, resulting in fertilizer waste and reduced utilization rate. Therefore, how to achieve multi-mode fertilizer mixing, prevent fertilizer adhesion and ensure its uniformity is an important technical challenge to improve the performance of the fertilization system. Summary of the invention

[0008] In view of the deficiencies in the prior art, the present invention provides a variable-width fertilizer spreader, which solves the problems of soil compaction, inflexible fertilizer spreading width and insufficient fertilizer uniformity during fertilization.

[0018] Preferably, the fertilizer spreading mechanism includes a conveying cabinet, which is installed by steel ropes, and is provided with card plates on both sides of the left and right sides of the conveying cabinet, and the card plates slide inside the cabinet, and are provided with motor three on the front and back sides of the conveying cabinet, and a folding rod one is fixed to the output end of motor three, a PLC module is provided on the top of the inner wall of the conveying cabinet, and an adaptive module is provided on the bottom of the inner wall of the conveying cabinet, and the PLC module and the adaptive module are electrically connected.

[0019] Preferably, one end of the folding rod one is rotated with a folding rod two, the tops of the folding rod one and the folding rod two are both provided with connecting ports, the bottoms of the folding rod one and the folding rod two are both provided with fertilizer spreading ports, and the fertilizer spreading ports and the connecting ports are connected by a pipeline.

[0022] Preferably, a rotating ring is fixed at the bottom of the scraper rod, and a stirring blade is fixed on the inner wall of the rotating ring.

[0023] Preferably, a motor six is ​​provided at the bottom of the barrel, a dragon blade is fixed to the output end of the motor six, and the dragon blade rotates inside the hollow column.

[0025] Working principle: When it is necessary to spread fertilizer, the corresponding fertilizer spreading mechanism is first connected to the cabinet on one side. At this time, the cabinet on the other side starts to move through the crawler, so as to pull out the required moving route through the steel rope. At this time, the rope reel rotates under the drive of motor 2 to control the tension and corresponding length of the steel rope. At this time, the steel rope stretched out through the fixed pulley is flush. At this time, the motor 1 is driven to drive the connecting column and gear 1 to rotate synchronously, so that gear 1 drives gear 2 on both sides to rotate, so that the threaded barrel follows gear 2. The cabinet is rotated synchronously. Under the influence of the thread, the thread cone cannot rotate synchronously because it is restricted by the limit rod, so it can only move up and down along the thread to assist the cabinet to fix the corresponding position. After the position is fixed, the conveyor cabinet begins to move through the steel rope. At this time, the fertilizer in the side barrels on both sides is poured into the barrel, and finally merged inside the barrel through the connection port with the barrel. After the fertilizer is merged, the motor five is driven to drive the hollow column to rotate, so that the hollow column drives the stirring block to stir the internal fertilizer. At the same time, the stirring block on the top will also drive the scraper to scrape the inner wall of the barrel. At the same time, the corresponding turbine blades will also stir, and under the synchronous rotation of the rotating ring with the turbine blades, the driven stirring blades will drive the fertilizer at the bottom of the barrel toward the center position, so that the dragon blades driven by the motor six will be transported to the top position through the hollow column for re-mixing and stirring, and finally the mixed fertilizer will be transported by the pump at the delivery port position, so that it is transmitted to the position of the connection port through the delivery pipe, and finally evenly distributed by the fertilizer spreading port for fertilization operation, and at the same time, the amount of pump output is controlled according to different needs to control the amount of fertilizer spreading. When the corresponding field fertilization width is different, the corresponding folding rod one can be driven by the motor three to rotate. At this time, the rotating folding rod one corresponding to the position connected to the folding rod two is also provided with an internal motor similar to the motor three, so that the folding rod two can rotate, so as to change the angle and change the width of fertilizer spreading, and the delivery pipe connected to the folding rod two position can also be wound by the drum driven by the motor four, and the corresponding delivery pipe can also be clamped in cooperation with the clamp block by the pressure exerted by the elastic potential energy of the spring on the movable clamp, so that the rotating drum can control the winding of the delivery pipe.

[0026] The present invention provides a variable-width fertilizer spreader, which has the following beneficial effects:

[0027] 1. The present invention controls the moving path and stability of the equipment through the rope conveying mechanism, preventing the equipment from tilting or unevenly distributed during the fertilization process. In addition, the fixed mechanism ensures the continuity and reliability of the fertilization operation and avoids the uneven fertilization caused by equipment displacement. This system design not only protects the soil structure, but also provides a good growth environment for crops, promotes the development of the root system and the effective absorption of nutrients, and ultimately helps to improve the yield and quality of crops.

[0028] 2. The invention introduces an adjustable width design, so that the fertilization operation can be flexibly adjusted according to the needs of different crops and fields. Through a similar folding mechanism, the convergence of the pipeline effectively avoids the interference and fragility of the overly long pipeline during the fertilization process, ensuring the smoothness and efficiency of the fertilization operation. This design makes the fertilization work more accurate, improves the fertilizer utilization rate, and thus optimizes the growth conditions of crops.

[0029] 3. The present invention can effectively prevent fertilizer from adhering to the inner wall through multi-mode operation. At the same time, the system design can transport the lumped fertilizer deposited at the bottom to the stirring area for stirring and crushing. This mechanism ensures the uniformity of the fertilizer before application and promotes the transfer of the bottom fertilizer to the central position so that it can be fully utilized again. Through this efficient stirring and transportation, the fertilizer waste in the fertilization process is significantly reduced, and the overall effect of fertilization is improved.

[0041] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Please refer to the attached Figure 1 -Attached Figure 3 The embodiment of the present invention provides a variable-width fertilizer spreader, comprising:

[0043] The cabinet 1 has a crawler 2 installed at the bottom thereof for moving the equipment;

[0044] A tightening mechanism, which is installed inside the cabinet 1 and is used to release and retract the moving rope;

[0045] A fixing mechanism, which is installed on both sides of the cabinet 1 and is used to fix the position of the cabinet 1;

[0046] A fertilizer spreading mechanism, which is installed on one side of the cabinet 1 and is used for spreading fertilizer;

[0047] A stirring mechanism, which is installed inside the fertilizer spreading mechanism and is used to mix the fertilizer;

[0048] The tightening mechanism includes a rope drum 3, which rotates inside the cabinet 1. The rope drum 3 is driven by a motor 16 installed on the outer wall of the cabinet 1. A fixed plate 4 is arranged between the rope drums 3. The fixed plate 4 is fixed through the inside of the cabinet 1, and a cylinder 5 is arranged on the top. A top cabinet 6 is fixed to the output end of the cylinder 5. A fixed pulley 17 is fixed to the top of the rope drum 3 through the top cabinet 6. A steel rope 15 is arranged between the rope drum 3 and the fixed pulley 17.

[0049] The fixing mechanism includes a side cabinet 7, which is installed on both sides of the cabinet 1. A motor 1 8 is arranged inside the side cabinet 7. A connecting column 9 is fixed to the output end of the motor 1 8. A gear 10 is fixed to the outer wall of the connecting column 9. A threaded cylinder 11 rotates inside the side cabinet 7. A gear 2 12 is fixed to the outer wall of the threaded cylinder 11. The gear 10 is meshed with the gear 2 12.

[0050] The threaded cylinder 11 is internally threadedly connected with a threaded cone 14 , and a limiting rod 13 for limiting sliding in the cabinet 1 is fixed on the top of the threaded cone 14 .

[0051] Specifically, when performing the fertilizer spreading operation, first, the fertilizer spreading mechanism is precisely docked with the cabinet 1 on one side. This process is crucial to ensure the stability and accuracy of the equipment during fertilization. Once the docking is completed, the cabinet 1 on the other side begins to move through the crawler 2. The stable operation of the crawler 2 provides a good foundation for subsequent operations. At the same time, the moving route is determined by the traction of the steel rope 15.

[0052] During this process, the rope reel 3 starts to rotate under the drive of the motor 2 16. The power output of the motor enables the rope reel 3 to effectively control the tension and length of the steel rope 15, ensuring that there will be no excessive relaxation or stretching during movement, maintaining the stability of the equipment, and the stretched steel rope 15 is kept flat through the fixed pulley 17, which is crucial to ensure the accuracy of the fertilizer spreading mechanism during movement;

[0053] Next, the driving motor 1 8 is activated, driving it to drive the connecting column 9 and the gear 1 10 to rotate synchronously. This process enables the gear 10 to effectively drive the gears 2 12 on both sides to rotate. The synchronous rotation of the gears not only improves the efficiency of the mechanical transmission, but also ensures the coordination between the components.

[0054] At the same time, the threaded barrel 11 is driven by the gear 2 12 and rotates synchronously. Due to the design of the thread, the threaded cone 14 cannot rotate synchronously under the restriction of the limit rod 13. At this time, the threaded cone 14 can only move up and down along the thread. This design effectively combines mechanical transmission with displacement control to ensure that the cabinet 1 is fixed in an accurate position.

[0055] Once the position is fixed, the conveying cabinet 18 begins to move through the steel rope 15. This movement process ensures the stability and accuracy of the conveying cabinet 18 through the previous tensioning and docking settings, so that the fertilizer spreading operation can proceed smoothly;

[0056] In summary, the whole process reflects the high efficiency and precision of the mechanical structure. Through the coordinated work of various components, the smooth implementation of the fertilization operation is achieved. This system design not only ensures the operation efficiency, but also provides a feasible technical solution for the future agricultural mechanization.

[0057] Please refer to the attached Figure 7 -Attached Fig.10 The fertilizer spreading mechanism includes a conveying cabinet 18, which is installed by a steel rope 15. A card plate 19 is provided on both sides of the conveying cabinet 18. The card plates 19 slide inside the cabinet 1. A motor 3 20 is provided on both sides of the conveying cabinet 18. A folding rod 1 21 is fixed to the output end of the motor 3 20. A PLC module 46 is provided on the top of the inner wall of the conveying cabinet 18, and an adaptive module 47 is provided on the bottom of the inner wall of the conveying cabinet 18. The PLC module 46 and the adaptive module 47 are electrically connected;

[0058] A folding rod 22 is rotated at one end of the folding rod 1 21, and a connecting port 24 is provided at the top of the folding rod 1 21 and the folding rod 22, and a fertilizer spreading port 23 is provided at the bottom of the folding rod 1 21 and the folding rod 22, and the fertilizer spreading port 23 and the connecting port 24 are connected by a pipeline;

[0059] A barrel 25 is provided on the top of the conveying cabinet 18, side barrels 26 are fixed on both sides of the barrel 25, a connecting plate 27 is fixed on the outer wall of the barrel 25, a water pump is provided inside the barrel 25, a conveying port 28 is fixed on the outer wall of the barrel 25, and a conveying pipe 29 is provided between the conveying port 28 and the connecting port 24;

[0060] A motor 6 44 is provided at the bottom of the barrel 25, and a dragon blade 45 is fixed to the output end of the motor 6 44, and the dragon blade 45 rotates inside the hollow column 38;

[0061] A winding disk 30 is fixed to one side of the connecting plate 27, and a motor 31 is provided on one side of the winding disk 30. A rotating drum 32 rotates between the winding disks 30, a clamping block 33 is fixed to the outer wall of the rotating drum 32, and a movable splint 34 is provided on the top of the clamping block 33. A fixed column 35 slides inside the movable splint 34, and a spring 36 is sleeved on the outer wall of the fixed column 35. One end of the spring 36 is fixed inside the clamping block 33, and the other end of the spring 36 is fixed to one side of the movable splint 34.

[0062] Specifically, during the fertilizer spreading operation, the conveying cabinet 18 starts to move by the traction of the steel rope 15. At this time, the fertilizer is poured into the side barrels 26 on both sides. These fertilizers will eventually converge inside the barrel 25 through the connection port with the barrel 25 to ensure uniform mixing. The mixed fertilizer is then transported by the pump at the conveying port 28, and the conveying pipe 29 effectively transmits the fertilizer to the connection port 24. In this process, the fertilizer will be evenly distributed to the fertilizer spreading port 23 to complete the fertilizer spreading operation.

[0063] In order to meet the needs of different crops and fields, the system can flexibly adjust the output of the pump to control the specific amount of fertilizer spread. This flexibility ensures the accuracy of fertilization and adapts to different operating conditions.

[0064] In the case of a change in the fertilization width requirement, the PLC module 46 sends instructions to the adaptive module 47 according to the corresponding instruction width change requirement, so that the adaptive modules 47 on both sides respectively control the corresponding motor three 20, so as to perform an intelligent method without manual self-control, so that the motor three 20 drives the folding rod one 21 to rotate. The rotation of the folding rod one 21 not only affects its own position, but also connects with the folding rod two 22. The folding rod two 22 is also provided with a motor similar to the motor three 20, so that the corresponding power can be provided to drive the folding rod two 22 to rotate. By adjusting the angles of the two folding rods, the width of the fertilizer spreading can be accurately changed to ensure that the fertilizer covers the area required for crop growth.

[0065] In addition, the conveying tube 29 connected to the folding rod 22 has further adjustment capability, and the rotating drum 32 driven by the motor 4 31 can realize the winding control of the conveying tube 29. The rotation of the rotating drum 32 not only enhances the flexibility of the system, but also improves the convenience of operation. In order to ensure that the conveying tube 29 can be firmly fixed in the appropriate position during the winding process, the system also introduces a spring 36. The elastic potential energy of the spring 36 can exert pressure on the movable clamping plate 34, so that it can effectively cooperate with the clamping block 33, thereby firmly clamping the conveying tube 29. This design ensures that during the rotation of the rotating drum 32, the conveying tube 29 will not be loose, causing unstable operation;

[0066] In summary, the system achieves precise and efficient fertilization operations through the synergistic effect of multiple mechanisms. Its flexible design not only improves the efficiency of fertilization, but also provides a solid guarantee for the healthy growth of crops.

[0067] Please refer to the attached Figure 4 -Attached Figure 6 The stirring mechanism includes a motor 37, which is arranged at the top of the barrel 25. A hollow column 38 is fixed to the output end of the motor 37. Stirring blocks 39 distributed in a circular array are fixed to the outer wall of the hollow column 38. The top stirring blocks 39 are all fixed with scraper rods 40, and turbine blades 41 are arranged inside the scraper rods 40.

[0068] A rotating ring 42 is fixed at the bottom of the scraper rod 40 , and a stirring blade 43 is fixed on the inner wall of the rotating ring 42 .

[0069] Specifically, during the fertilizer processing, the fertilizer is first poured into the side barrels 26 on both sides. After a suitable period of time, the fertilizer will be merged inside the barrel 25 through the connection port with the barrel 25. The merged fertilizer needs to be fully mixed to ensure the consistency and effect of fertilization. At this time, the system starts the drive motor 5 37, which is responsible for driving the hollow column 38 to rotate;

[0070] The rotation of the hollow column 38 will directly drive the stirring block 39 to evenly stir the fertilizer inside. The stirring block 39 is designed to improve the stirring efficiency so that the fertilizer can be evenly mixed in a short time. In addition, the top of the stirring block 39 is also equipped with a scraper 40, which is used to effectively scrape the inner wall of the barrel 25 to ensure that every part of the fertilizer can be stirred, thereby avoiding the fertilizer being deposited on the inner wall and not being fully utilized;

[0071] At the same time, the operation of the turbine blade 41 is also in progress. The design of the turbine blade 41 helps to improve the fluidity of the fluid, so that the fertilizer can flow better inside the barrel 25. As the turbine blade 41 rotates synchronously, the rotating ring 42 also rotates to drive the stirring blade 43 to work. This process allows the fertilizer at the bottom of the barrel 25 to effectively converge to the center position, promoting sufficient mixing.

[0072] During this process, the motor 6 44 is activated to drive the dragon blade 45 to work, and the dragon blade 45 transports the stirred fertilizer to the top position through the hollow column 38 to mix and stir again. This design ensures the continuity and efficiency of the transportation and stirring of the fertilizer, so that the fertilizer reaches the best mixing state before application;

[0073] Through the coordinated operation of the above systems, the fertilizer processing process is effectively optimized, ensuring the efficiency and reliability of fertilization operations. The precise design of each link not only improves the mixing quality of fertilizers, but also lays a solid foundation for subsequent fertilization operations. The innovation and application of this system will play an important role in agricultural production and improve the growth quality and yield of crops.
