[0027] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, further, the embodiments of the present disclosure are described below in conjunction with the examples and drawings, the illustrative embodiments of the present disclosure and the descriptions thereof are only used to explain the embodiments of the present disclosure and do not limit the embodiments of the present disclosure.

[0028] As shown in Figure 1 and Figure 2 , the anti-caking fertilizer storage device of the present application comprises a storage bin 1, a stirring rod 21 assembly 2, a discharge port 3 and a support frame 4. The design of each part aims to prevent the formation of caking of the fertilizer during storage, and to ensure the uniformity and smoothness of the material during discharge.

[0029] Specifically, the storage bin 1 is the core part of the device, which is used to store various granular or powdery fertilizers. The storage bin 1 is a closed structure with a certain wall thickness to prevent external environmental factors from affecting the physical properties of the internal material, such as moisture and other factors that may increase the adsorption effect between fertilizer particles. The top of the storage bin 1 can be provided with a feeding device or a sealing cover to facilitate the replenishment of the material inside; the bottom is connected with a specially designed discharge port 3 for conveying the uniformly mixed fertilizer to the subsequent processing process or directly applying it to the agricultural cultivation environment.

[0030] Referring to Figure 2 and Figure 3 , the stirring rod assembly 2 is installed inside the above-mentioned storage bin 1, arranged vertically to the bottom plane in the longitudinal space, which plays the effect of driving the material in the whole bin to move up and down. It is composed of a plurality of stirring rods 21, each of which is in the form of an elongated rod body, and gradually reduces its cross-sectional area along the axis direction, so that the part near the top is relatively thick, and the lower it is, the thinner it becomes. Such a structural design helps the material to slide more gently along the inclined side to the low point without blocking the pipeline outlet due to excessive gravity. At the same time, a number of irregularly arranged spiral leaves 22 are distributed on each stirring rod 21, which can effectively cut through the large particle clusters therebetween and guide the small individuals of different diameters to interweave with each other to promote the homogenization process.

[0031] In addition, the spiral blades 22 are not in the traditional form, but are improved and optimized according to actual needs, that is, on the same stirring rod 21, the angle of each segment is arranged in an increasing manner from the top to the bottom. The spiral blades 22 at the high position are bent at a small angle, which is beneficial to initially break the large-size collection units that are loosely accumulated on the surface layer but have not yet completely integrated into one. As the height decreases, the bending degree of the blades in the lower region increases, so that a more intense stirring effect can be generated near the bottom position, and then the small groups that have entered the late aggregation stage or are relatively dense are broken into isolated primary particles in the initial state, so that no obvious local density difference is generated in the entire system to hinder the normal flow path.

[0032] Finally, the support frame 4 is responsible for supporting and fixing the overall framework to stably exist. This structure is arranged around the periphery of the entire fertilizer storage device and is rigidly connected with the ground or other bearing platforms. It not only can bear the pressure load applied by all the parts above, but also can provide a relatively stable operation platform to ensure that the entire machine runs in a horizontal state in the working state. In addition, the support frame 4 can be provided with adjustable height supports or foot pads to adjust the position and inclination of the entire set of equipment to meet different on-site operation requirements.

[0033] Through the above design scheme, the gradually changing structure design of the multiple vertically arranged stirring rods 21 of the anti-caking fertilizer storage device of the present application, in cooperation with the structure feature that the top is thick and the tail is thin, enables the material to be smoothly transferred downward under the combined action of its own gravity and the additional rotating thrust without large-area accumulation. The angle difference layout of the spiral blades 22 ensures that each segment in the entire height direction has corresponding stirring intensity and speed, and in particular, when approaching the bottom, the blades with a larger angle will bring a more intense mixing effect.

[0034] In an embodiment, the spacing between the stirring rods 21 of the anti-caking fertilizer storage device of the present application is set to 50-150 mm. The setting of this spacing range aims to adapt to fertilizers of different particle sizes and ensure that they can be fully mixed during stirring. The multiple stirring rods 21 in the storage bin 1 are vertically distributed and arranged in the vertical direction, and each rod is provided with irregular spiral blades 22. By adjusting the spacing of the stirring rods 21, both the over-deposition of large particles and the uniform mixing of small particles can be ensured, and the caking of the fertilizer due to long-term storage can be prevented. This design is particularly suitable for storing fertilizers of different properties and particle sizes, so that the device can maintain good material dispersibility both in static storage and in dynamic mixing operation.

[0035] In particular, different spacing combinations can be selected to meet specific requirements. For example, in some cases, the spacing of the stirring rods 21 can be set to 50 mm to accommodate larger fertilizer particles, ensuring good flow and mixing between larger particles. In another application environment, if smaller and more uniform fertilizer particles need to be processed, the spacing of the stirring rods 21 can be increased to 150 mm. In this way, not only can there be enough space for small particles to move and diffuse, but it can also avoid unnecessary damage or excessive friction caused by over-stirring of smaller particles. When installed, each stirring rod 21 is uniformly fixed in the vertical direction within the support frame 4, and the spacing between them is ensured to be consistent in the entire height direction, to ensure the consistency of the mixing effect. In addition, the angle change of the spiral blades 22 and the tapered design of the stirring rods 21 from the top to the bottom further assist the effective mixing and smooth downward delivery of the material inside.

[0036] In one embodiment, specifically referring to Figure 2 The top end of the anti-caking fertilizer storage device stirring rod 21 is provided with a tapered guide portion 23 to guide the smooth entry of the material into the spiral blade 22 area. The overall structure of the device is compact and reasonable, and the mutual cooperation between the components improves the overall function. Specifically, the storage bin 1 is used to store fertilizer, and the bottom is provided with a discharge port 3 to realize the release of the fertilizer, and the entire device is supported and fixed by the support frame 4. During storage and output, the stirring rod 21 assembly 2 is responsible for the internal agitation of the material. The stirring rod 21 is arranged in the vertical direction, and each is equipped with irregular spiral blades 22, which can well adapt to different fertilizer particle sizes and ensure the good state of the fertilizer during storage.

[0037] In one embodiment, the tapered guide portion 23 described in the present application is located at the top of the stirring rod 21 and is composed of a smooth transition surface, which gradually decreases in diameter from top to bottom to form a natural narrowing trend. Such a design can seamlessly connect the tapered portion with the entrance above the storage space, and play a good guiding role in the material entering process, reducing the problem of local accumulation caused by material jamming. In addition, after mixing different batches of new and old materials, the smooth guidance through the tapered surface can more smoothly flow into the lower working section with spiral distribution blades for further dispersion treatment, thereby ensuring that the material can remain loose during the entire storage process without hardening or solidification.

[0038] For example, the conical structure on the stirring rod 21 can be manufactured by precision machining, with strict control of the taper and dimensional tolerance; during installation, the special-shaped section is accurately fixed to the topmost position and tightly connected with other structures, ensuring that it is always in good working condition during operation to efficiently guide the incoming and outgoing materials. At the same time, factors such as material selection and surface treatment process need to be considered to ensure excellent durability and smooth operation performance over a long period of use.

[0039] In one embodiment, as shown in FIG. 1, the anti-caking fertilizer storage device of the present application is characterized by the irregular helical blade 22, which is designed uniquely, i.e., the helical blade 22 has a gradually increasing pitch from the top to the bottom. This design is based on a deep understanding and application of the material flow characteristics during fertilizer storage and transportation, so that at different height positions, the helical blade 22 can provide a pushing action that is adapted to the height of the layer, ensuring smooth movement of the material without stagnation. Figure 2 The special morphological changes of the helical blade 22 are adjusted according to the behavior of the fertilizer at different storage depths. As the height of the fertilizer accumulation changes, the material density and internal friction will also change, which poses a challenge to the smoothness of the discharge. Therefore, at higher positions, the material is light, thin and loose, and at this time, smaller pitch can more effectively capture and move a smaller amount of material; as the depth increases, near the bottom of the device, the material becomes more dense and may form a large mass of a certain hardness, which requires a larger pitch to produce a more powerful action to break and transport the material.

[0040] For example, it is possible to manufacture such variable-pitch helical blades 22 by adjusting the helical forming process or using a segmented prefabrication splicing method. The manufacturing process divides the helical blade 22 into multiple segments, each with a specific pitch specification, and then installs them on the stirring rod 21 in the order from top to bottom, to ensure that each layer matches the optimal operating parameters to meet the requirements of material flow at the corresponding position. These measures together ensure that the device can maintain good condition throughout the working range, maintain stable material flow and prevent caking.

[0041] In one embodiment, each stirring rod 21 of the anti-caking fertilizer storage device of the present application is installed with a vibration generator 25. Through the periodic vibration function, the agglomerated material is broken, which helps to maintain the fluidity of the material. The core of this feature design is to use vibration technology to overcome the caking problem that is prone to occur in traditional static storage. The vibration generator 25 is installed on the stirring rod assembly 2, which can effectively vibrate the fertilizer inside the storage device during operation, thereby preventing large-area particle aggregation caused by long-term static placement.

[0042]

[0043] ​In a specific design, the vibration generator 25 is arranged on each agitating rod 21 installed in the vertical direction in the storage bin 1, and is firmly connected with the agitating rod 21 through a specific mounting structure to ensure reliable power transmission. The inside of the vibration generator 25 is composed of a small motor and a counterweight wheel connected therewith. When the motor operates, the counterweight can be driven to rotate to generate centrifugal force, thereby generating periodic reciprocating force acting on the external structure. In addition, in order to match the optimal vibration effect under different use environment requirements and adapt to the changes of different material characteristic parameters, each vibration generator 25 is provided with a frequency adjustment and vibration intensity control function module. For example, a lower vibration frequency can be selected for fine powder materials, and a higher vibration intensity can be set for fertilizers with large density and easy adhesion. Such technical means ensures smooth operation of the entire storage system and provides a good premise for later discharging.

[0044] In one embodiment, a plurality of through holes 26 are arranged on the spiral blade 22 of the anti-caking fertilizer storage device. The arrangement of these through holes 26 helps to further disperse the material, reduces the occurrence of caking while ensuring more uniform mixing of the fertilizer. This design enhances the flowability of the material and improves the operating efficiency of the entire device.

[0045] In terms of structure, the through holes 26 are specifically distributed on the surface of the spiral blade 22, so that they can work together with the agitating rod 21 assembly 2 to achieve multiple crushing and dispersion of the material. The number and arrangement of the through holes 26 are adjusted according to the specific properties of the fertilizer. Through the design of hole diameter, hole spacing and different arrangement patterns at different height sections, it is ensured that fertilizers of any particle size can be fully mixed and uniformly transported.

[0046] In order to prevent caking and improve mixing efficiency, in one embodiment, the through holes 26 of the device penetrate the irregular spiral blade 22 and change in angle with the distance from the vertex at each height section. These holes, in combination with the spiral blade 22, can produce local airflow or liquid flow changes during agitation, thereby improving material transport performance and mixing effect. For example, when the device is operating, some small particles can be redistributed to other areas through the through holes 26, while larger particles will be continuously torn and dispersed during the spiral propulsion process, ensuring that all components can be effectively mixed without easy agglomeration. In addition, the presence of the through holes 26 also allows air to enter the inside of the storage bin 1 to maintain a proper humidity level, avoiding the problem of caking caused by excessive humidity.

[0047] As Figure 2As shown, in one embodiment, a flexible sealing gasket 27 is provided between the agitator rod 21 and the inner wall of the storage bin 1 to ensure that there is no dead zone and to prevent material accumulation. This design adds sealing elements to the outer side of the agitator rod 21 and the inner edge of the storage bin 1 to form a tight closed environment that prevents the material from spreading along the flow path to non-working areas. The flexible sealing gasket 27 not only has good mechanical adaptability, can effectively fill the small gaps caused by size differences during equipment manufacturing or installation, but also can buffer the impact on the structure during operation, thereby ensuring long-term stability. In addition, the gasket is made of wear-resistant and corrosion-resistant materials, which not only ensures flexibility but also enhances the overall service life of the system.

[0048] For example, the flexible sealing gasket 27 can be installed around the outer periphery of the agitator rod 21, close to but not in contact with the inner peripheral wall of the storage bin 1. One end of the sealing gasket tightly fits the surface of the agitator rod 21, and the other end is adjacent to but not in contact with the inner wall of the storage bin 1, and is stably connected by a special clamp or fixing ring. The gasket itself is composed of multiple layers of elastic material, including protective layers on the inside and outside and a supporting skeleton in the middle. The layers are combined with each other to form a unified and flexible whole, ensuring that it can flexibly deform to adapt to changes in working conditions and maintain good sealing effect for a long time.

[0049] Referring back to Figure 1 In one embodiment, the support frame 4 of the anti-caking fertilizer storage device of the present application uses adjustable legs 41, which are installed at the bottom corners of the support frame 4 to adjust the height and level of the entire device. By fine-tuning the height of the legs 41, the overall stability of the device can be ensured. This not only improves the stability of the device, but also provides the best working conditions for the agitator rod 21 assembly 2. In addition, the adjustable legs 41 also facilitate flexible adaptation to uneven ground, ensuring that the storage bin 1 and other components are in the ideal vertical position.

[0050] The design of the adjustable legs 41 includes a fixed sleeve and a telescopic inner tube. The fixed sleeve is fixedly connected with the support frame 4, and the inner tube is adjusted in height by threads or locking screws. This design allows the support frame 4 to remain stable even on uneven ground by adjusting the height of each adjustable leg 41. Specifically, during installation and use, first insert the inner tube of each adjustable leg 41 into the corresponding fixed sleeve, and then lock the desired height by manually rotating the nut or adjusting the handle according to actual needs. This design realizes effective adaptation and support for different terrains, ensuring the safety and reliability of the overall device.

[0051] For example, after the operator completes the initial installation of the device, the specific position and height of each leg 41 can be further adjusted according to the actual situation, and the locking mechanism is used to fix the extension length of the leg 41, so as to realize the maximum stability of the device. At the same time, by accurately adjusting the height difference of each leg 41, the center point of the device is ensured to be perpendicular to the horizontal plane, so that the stirring rod 21 assembly 2 located inside the storage bin 1 can work in a uniform and stable environment.

[0052] In one embodiment, the storage bin 1 of the anti-caking fertilizer storage device of the present application is provided with a feeding hopper 12 at the top of the storage bin 1, which is used to put the material into the storage bin 1. The feeding hopper 12 is sealingly connected with the storage bin 1 through flanges or other reliable connection methods, so as to minimize the influence of the external environment on the stored material. The bottom of the storage bin 1 is designed to be gradually smaller, forming a conical structure. This geometric design helps to slow down the speed of the material entering the bin, so as to better control the flow rate of the material. At the same time, such design also creates favorable conditions for subsequent stirring operation, so that the stirring process is more sufficient and uniform.

[0053] Specifically, the inside of the storage bin 1 is provided with a stirring rod 21 assembly 2. After the material is added by the feeding hopper 12, it can smoothly pass through the relatively wide space at the top and pass through the part with a gradually narrowing caliber while descending, at which time the action range of the stirring assembly is gradually concentrated, which is more conducive to exerting force on the material. Since the discharge port 3 is located at the bottom of the entire system, such design can also prevent excessive feeding during high-flow feeding. For example, when the volume of the storage bin 1 and the design parameters of the discharge port 3 are fixed, the tapered bottom can help the system to maintain appropriate material flow density and stable output.

[0054] Specifically, the feeding hopper 12 is installed at the upper center position of the storage bin 1 and is well connected with it. With such a design, it is not only convenient for daily addition work, but also can limit the amount of material entering the warehouse per unit time while ensuring smooth feeding. By scientifically designing the angle between the feeding hopper 12 and the transition area of the conical container and the diameter change curve inside the container, the material can flow smoothly under the action of gravity until it reaches the area of the spiral blade 22. In this way, combined with the design of the discharge end of a specific shape, the overall device can achieve the ideal material processing effect without congestion or accumulation.

[0055] In one embodiment, one of the design features of the anti-caking fertilizer storage device of the present application is that the end of the spiral blade 22 and the discharge port 3 are provided with crushing teeth 31 (see Figure 2). The installation position of this component is crucial to ensure that the material is in the form of small particles or powder in the last discharge process. By reasonable arrangement, the material is kept loose throughout the storage device. Specifically, the space near the discharge port 3 is optimized for the configuration of this special crushing system. When the material finally enters the discharge stage from the spiral conveying path, it must pass through the system for processing to be discharged.

[0056] In this design, the structural design of the spiral blade 22 also needs to be adapted to the crushing teeth 31. A series of interlaced crushing teeth 31 are arranged near the end of the spiral blade 22 close to the discharge port 3. The density and angle of these tooth-shaped elements are precisely calculated and arranged for possible large particle size solids. In addition, in order to ensure smooth passage of the material without creating new risk of blockage, each crushing tooth 31 has undergone strict wear resistance tests and is made of a material with moderate hardness but sufficient wear resistance.

[0057] For example, to achieve this feature, the crushing teeth 31 can be fixed on a small module that can be detached and easily cleaned. The module is directly installed to the inner wall of the discharge port 3, maintaining a close and reasonable distance from the end of the spiral blade 22. By adjusting the gap and inclination angle between the crushing teeth 31, the uniformity and stability of the finished particle size can be controlled. During operation, as the spiral blade 22 rotates to push the material forward, the crushing teeth 31 continuously cut any large pieces of material that may appear, ensuring that each part discharged reaches the ideal state of fine crushing, thereby eliminating the risk of large particles being discharged.

[0058] In actual operation, when the device is in use, the fertilizer is poured into the storage bin 1. After starting, the stirring rod 21 assembly 2 begins to operate, and the multiple stirring rods 21 arranged in the vertical direction rotate and drive the irregular spiral blades 22 on them to rotate to adapt to fertilizers of various particle sizes, ensuring that the material is fully mixed and deposited. Due to the tapered design of the stirring rod 21 from top to bottom, the material can be smoothly conveyed downward while maintaining uniform stirring. The angle of the spiral blade 22 gradually increases with the change in height, which helps to form different relative movements between different height layers, thereby better breaking up large particle size fertilizer lumps. The finally mixed and lump-free fertilizer is released through the discharge port 3 provided at the bottom of the storage bin 1. The entire process is supported by the support frame 4 to ensure the stability and reliability of the device operation.
