Transport device for organic fertilizers

Abstract

This invention belongs to the field of fertilizer packaging technology and proposes an organic fertilizer transportation device, including a first conveyor with a support frame above it supporting a storage silo. The storage silo comprises a first silo and a second silo body. The bottom of the first silo body has a discharge port with a gradually decreasing diameter and an internal sealing seat, the side wall of which is adapted to the inner wall of the discharge port. The second silo body is located below, with the bottom of the discharge port inserted into it, and a lifting device for raising and lowering the sealing seat is installed inside. The second silo body has a fixed shell, a liquid outlet on its side wall connected to a first spray head, and the shell is connected to a pressure pump via a first water pipe. The inner wall has an annular pipe connected to the first water pipe via a second water pipe, and the annular pipe is connected to a second spray head. The side wall of the sealing seat is located between the two spray heads. The double spray heads ensure that the anti-caking agent fully coats the fertilizer, resulting in a significant anti-caking effect. The lifting device drives the sealing seat to rise and fall intermittently, realizing intermittent feeding and spraying. This saves on anti-caking agent and, by preventing the fertilizer from rapidly passing through the spraying area during continuous feeding, prolongs the contact time between the fertilizer and the anti-caking agent, ensuring the treatment effect.

Description

Technical Field

[0001] This invention belongs to the field of fertilizer packaging technology, specifically relating to a transportation device for organic fertilizer. Background Technology

[0002] In the agricultural production system, fertilizers are core materials for regulating crop nutrient supply and ensuring the yield and quality of agricultural products. Their application effect directly affects agricultural production efficiency and sustainable development. With the increasing demand for precision fertilization in modern agriculture, multi-component fertilizers such as nitrogen-phosphorus-potassium compound fertilizers and slow-release fertilizers have gradually replaced single-component fertilizers as the market mainstream due to their ability to achieve synergistic nutrient supply and improve fertilizer utilization. However, during the packaging process, fertilizers undergo production, storage, and transportation, and the common problem of clumping during this process has become a key bottleneck restricting their quality and user experience.

[0003] Fertilizer clumping is essentially the result of physical or chemical changes on the surface of the granules, leading to the formation of adhesive forces between the granules. From an internal perspective, components in compound fertilizers, such as urea and ammonium sulfate, are highly hygroscopic. When environmental humidity changes, they easily absorb moisture from the air, causing the granule surface to dissolve and form a saturated solution. When the environment dries, the moisture evaporates, and the solute crystallizes, binding adjacent granules together. Simultaneously, residual free acids and impurities from the fertilizer production process accelerate the chemical reactions between granules, forming stable clumping nuclei. From an external perspective, factors such as the intensity of stacking during storage, fluctuations in environmental temperature and humidity, and prolonged storage time all further exacerbate clumping, with some fertilizers even forming hard lumps that are difficult to break after stacking.

[0004] The negative impacts of fertilizer caking permeate the entire industry chain: For manufacturers, caking leads to production line blockages, inaccurate packaging and metering, and increased equipment wear and tear and production downtime risks; for distributors, caking fertilizer is prone to particle breakage and nutrient loss, reducing its commercial value; for farmers, caking fertilizer requires manual crushing before use, which not only increases labor intensity but also causes uneven nutrient distribution during application due to uneven crushing, affecting crop growth and, in severe cases, even causing seedling burn due to excessively high local fertilizer concentrations. Furthermore, traditional crushing methods such as manual hammering and mechanical compaction may damage the fertilizer's slow-release structure or coating, resulting in the loss of its special fertilizing effects. Summary of the Invention

[0005] In view of this, the present invention provides a transport device for organic fertilizer to solve the problem of easy clumping of existing fertilizers.

[0006] The technical solution adopted in this invention is as follows:

[0007] An organic fertilizer transport device includes a first conveyor, a storage silo supported above the first conveyor by a bracket, the storage silo including a first silo body and a second silo body, the bottom of the first silo body having a discharge port with a diameter gradually decreasing from top to bottom, a sealing seat inside the discharge port, the side wall of the sealing seat being adapted to the bottom shape of the inner wall of the discharge port, the second silo body being located below the first silo body, the bottom of the discharge port being inserted into the second silo body, the second silo body having a lifting device for raising and lowering the sealing seat; a shell is also fixed inside the second silo body, the side wall of the shell having a plurality of liquid outlets extending circumferentially, each of the liquid outlets being connected to a first spray head, the shell being connected to an external pressure pump through a first water pipe; an annular pipe is provided on the inner wall of the second silo body, the annular pipe being connected to the first water pipe through a second water pipe, the annular pipe being connected to a plurality of second spray heads, the side wall of the sealing seat being located between the first spray heads and the second spray heads.

[0008] After adopting the above technical solution, it should be noted that the first conveyor is used to receive and transport the fertilizer falling from each storage bin; the storage bins are used to classify and store fertilizer, and the first bin body serves as the main storage space for fertilizer, used to hold a large amount of fertilizer to be used; the diameter of the discharge port gradually decreases from top to bottom, forming a converging structure, which facilitates the concentrated falling of fertilizer and prevents fertilizer from accumulating at the outlet; the sealing seat is adapted to the shape of the inner wall of the discharge port, and controls the flow of fertilizer in the first bin body by fitting and separating from the discharge port; the second bin body is the area for fertilizer discharge and anti-caking treatment, providing installation space for components such as the lifting device and spray structure; the lifting device drives the sealing seat. The lifting mechanism enables intermittent control of the material feeding. The housing provides a mounting platform for part of the lifting device, while its side wall outlet provides a channel for the anti-caking agent to be sprayed. The first and second spray heads spray the anti-caking agent onto the falling fertilizer from the inside and outside of the fertilizer, respectively, ensuring uniform spraying. The annular pipe allows the second spray heads to be evenly distributed around the circumference of the second compartment, achieving all-around spraying. The first and second water pipes provide a transport channel for the anti-caking agent, delivering the pressurized anti-caking agent from the pressure pump to the housing and the annular pipe, respectively. The pressure pump provides power for the transport of the anti-caking agent, ensuring that the anti-caking agent can be sprayed from the spray heads at a certain pressure. In the initial state, the sealing seat is in contact with the bottom inner wall of the discharge port of the first compartment, preventing the fertilizer from falling. During operation, the pressure pump is activated, pressurizing the external anti-caking agent and splitting it into two streams through the first water pipe. One stream is sent into the housing, and the other stream is sent into the annular pipe through the second water pipe. The anti-caking agent entering the housing drives the lifting device, causing the sealing seat to rise. A gap is formed between the sealing seat and the discharge port, allowing the fertilizer in the first chamber to fall into the second chamber through the gap. Simultaneously, the anti-caking agent inside the housing is sprayed out from the discharge port through the first spray head under pressure, while the anti-caking agent in the annular pipe is sprayed out through the second spray head. Since the side wall of the sealing seat is located between the two spray heads, the falling fertilizer is sprayed by both the inner first spray head and the outer second spray head, ensuring that the anti-caking agent evenly coats the surface of the fertilizer granules. When it is necessary to stop feeding, the pressure pump extracts the anti-caking agent from the housing, the lifting device lowers the sealing seat, and it re-fits the discharge port, blocking the feeding. The first and second spray heads also stop spraying, forming a cycle of intermittent feeding and intermittent spraying.In this design, the separate design of the first and second compartments separates the storage and processing functions, improving operational flexibility. The constriction structure of the discharge port and the cooperation of the sealing seat ensure effective control of the discharge, preventing leakage. The double spray head setup of the first and second spray heads allows the anti-caking agent to fully coat the fertilizer, significantly improving the anti-caking effect and extending the fertilizer storage time. The lifting device drives the sealing seat to rise and fall, allowing the discharge port to open or close. Furthermore, if intermittent discharge is required, the lifting device can intermittently raise and lower the sealing seat, achieving intermittent discharge and intermittent spraying. This intermittent spraying method not only saves on the amount of anti-caking agent used but also allows for more sufficient contact time between the fertilizer and the anti-caking agent (because during continuous discharge, the fertilizer falling later pushes the preceding fertilizer through the spray zone quickly, and the particles only remain in the spray for a brief moment).

[0009] Preferably, the lifting device includes a piston plate and a piston rod. The piston plate is slidably embedded in the housing and divides the interior of the housing into an upper cavity and a lower cavity. The first water pipe is connected to the lower cavity, and in the initial state, the liquid outlet is located in the upper cavity. One end of the piston rod is connected to the piston plate, and the other end passes through the top of the housing and is connected to the bottom of the sealing seat.

[0010] With the above technical solution, it should be noted that the piston plate slides within the housing, driving the piston column to rise and fall, thus dividing the housing into two independent chambers for pressure control. The piston column, as a force transmission component, converts the linear motion of the piston plate into the rising and falling motion of the sealing seat, connecting the piston plate and the sealing seat. The first water pipe is connected to the lower chamber, providing a channel for the anti-caking agent to enter the lower chamber, and uses fluid pressure to drive the piston plate. Initially, the pressure in the lower chamber is low, the piston plate is in a low position, the piston column drives the sealing seat to fit against the outlet, the liquid outlet is located in the upper chamber, there is no pressure difference between the upper chamber and the outside, and the spray head does not spray liquid. When feeding is required, the pressure pump pumps the anti-caking agent into the lower chamber, increasing the pressure inside and pushing the piston plate upward. The piston plate drives the piston column to rise synchronously, pushing the sealing seat upward and creating a gap between the sealing seat and the outlet, allowing the fertilizer to fall. As the piston plate continues to rise, when it moves above the position where the upper chamber connects to the liquid outlet, the anti-caking agent enters the liquid outlet, creating a passage between the outlet and the outside, allowing the anti-caking agent to be sprayed from the first spray head, achieving spraying. When stopping is required, the pressure pump extracts the anti-caking agent from the lower chamber, reducing the pressure inside. The piston plate descends under its own weight and the pressure of the fertilizer, the piston column drives the sealing seat to reset, and the piston plate returns to its initial position. The liquid outlet is back in the upper chamber, spraying stops, and feeding is interrupted. In this design, by setting up a piston plate and piston column, the device uses the pressure of the anti-caking agent itself to drive the piston plate to move, thereby achieving the function of raising or lowering the sealing seat without the need for an additional power source. Furthermore, the integrated design of the lifting device and the anti-caking agent conveying system enables the feeding and spraying actions to work in coordination, improving the integration and working efficiency of the device.

[0011] Preferably, the top of the sealing seat is provided with a stirring rod; the bottom of the piston rod is rotatably connected to the piston plate, and the piston rod is movably connected to the top of the housing. The housing is also provided with a linkage device, which can drive the piston rod to rotate when the piston rod rises or falls. The stirring rod is provided with stirring blades, which are perpendicular to the stirring rod.

[0012] After using the above technical solution, it should be noted that the stirring rod is used to disperse the fertilizer that has clumped together at and near the discharge port of the first compartment, so as to avoid fertilizer clumping and causing material blockage; the piston column has both lifting and rotating functions, which not only drives the sealing seat to lift and control the material discharge, but also drives the sealing seat to rotate so that the stirring rod can play its role. Its rotational connection with the piston plate ensures that the rotation does not affect the linear sliding of the piston plate, and its movable connection with the top of the housing provides flexible space for lifting and rotation; the linkage device converts the axial movement of the piston column into circumferential rotational motion. When the pressure pump supplies pressure into the housing, pushing the piston plate upward, the piston plate drives the piston column to rise synchronously. During the ascent, the linkage device inside the housing generates a circumferential force on the piston column. Because the bottom of the piston column is rotatably connected to the piston plate and the top is movably connected to the housing, the piston column rotates while rising. The rotation of the piston column drives the sealing seat to rotate synchronously, and the stirring rod on top of the sealing seat rotates with the sealing seat, agitating the fertilizer that has solidified at the discharge port of the first compartment and during the descent. When the pressure pump pumps liquid and causes the piston plate to descend, the piston column descends with the piston plate, and the linkage device also drives the piston column to rotate in the opposite direction. The stirring rod continues to rotate, further cleaning up any remaining clumps of fertilizer until the sealing seat is in contact with the discharge port, and the discharge stops. In this design, the stirring rod effectively solves the problem of fertilizer easily solidifying in the storage silo, causing poor discharge, and ensures that the fertilizer can fall smoothly. The linkage device cleverly combines the lifting and rotating actions of the piston column, so that the agitation action of the stirring rod and the lifting action of the sealing seat are synchronized, eliminating the need for an additional power source to drive the stirring rod.

[0013] Preferably, the piston rod has an arc-shaped groove on its side wall, the arc-shaped groove having a higher end and a lower end; the linkage device includes a guide rod, one end of which is connected to the inner wall of the housing, and the other end is slidably embedded in the arc-shaped groove.

[0014] After adopting the above technical solution, it should be noted that the arc-shaped groove is the core structure for force conversion. Through the difference in height between its high and low ends, it converts the fixed support of the guide rod into a circumferential force that drives the piston rod to rotate. One end of the guide rod is fixed to the inner wall of the housing, providing a fixed support point for the movement of the piston rod, while the other end is embedded in the arc-shaped groove. When the piston rod rises and falls, it slides along the arc-shaped groove and generates a reaction force on the arc-shaped groove. The setting of the higher and lower ends makes the arc-shaped groove form a slope, providing a basis for the sliding of the guide rod and the transmission of force. As the piston rod rises under the action of the piston plate, the guide rod embedded in the arc-shaped groove remains in a fixed position. The rise of the piston rod causes the arc-shaped groove to slide relative to the guide rod, and the end of the guide rod moves from the higher end to the lower end of the arc-shaped groove. Because the arc-shaped groove is curved, the guide rod generates a lateral thrust on the side wall of the arc-shaped groove, pushing the piston rod to rotate around its own axis. When the piston rod descends, the end of the guide rod slides from the lower end to the higher end of the arc-shaped groove, similarly generating a lateral thrust in the opposite direction on the arc-shaped groove, causing the piston rod to rotate in the opposite direction. Throughout the entire process, the guide rod remains embedded in the arc-shaped groove, ensuring a continuous and stable transmission of force.

[0015] Preferably, the spray tip of the first spray head is tilted upwards, and the spray tip of the second spray head is tilted downwards.

[0016] With the above technical solution adopted, it should be noted that the design of the first spray head tilting upwards and the second spray head tilting downwards has the core advantage of significantly increasing the coverage and three-dimensional space of the fog screen through complementary directions, thereby improving the contact efficiency between the anti-caking agent and the fertilizer. When the first spray head sprays upwards at an angle, the anti-caking agent mist diffuses upwards along the tilt direction, breaking through the limitations of horizontal spraying and covering the upper and middle areas of the second chamber, especially targeting fertilizer particles at a higher position during the initial fall from the outlet gap. When the second spray head sprays downwards at an angle, the mist extends downwards to the lower and middle parts of the second chamber, forming a vertical connection with the mist from the first spray head. The mists from the two spray heads converge and merge inside the second chamber, forming a three-dimensional fog screen extending from top to bottom, rather than a single planar fog layer. This three-dimensional fog screen not only expands the horizontal coverage width but also increases the vertical coverage height. When fertilizer particles slide down the conical top of the sealing seat and diverge through the second compartment, they will travel through this three-dimensional fog screen throughout the entire process. No matter what stage the particles are in on their falling trajectory, they can fully contact the anti-caking agent droplets.

[0017] Preferably, the top of the sealing seat has a conical structure.

[0018] After adopting the above technical solution, it should be noted that when the fertilizer in the first compartment falls, the conical surface can guide the fertilizer to slide quickly towards the edge of the sealing seat, avoiding the accumulation and residue of fertilizer on the top of the sealing seat and reducing the risk of clumping.

[0019] Preferably, there are multiple storage bins, which are spaced apart along the length of the first conveyor.

[0020] After adopting the above technical solution, it should be noted that multiple storage bins can store basic fertilizers such as nitrogen, phosphorus, and potassium, as well as different component materials such as micronutrients and synergists, to achieve classified storage and precise quantity control. With the storage bins arranged at intervals along the first conveyor, combined with the intermittent feeding function of the storage bins, different component fertilizers will fall into the conveyor in batches in an orderly manner, rather than being piled up in large quantities at the same time. This "staggered feeding" allows the agitator in the subsequent mixing bin to have more time to mix the components evenly, ensuring uniform nutrients in the compound fertilizer.

[0021] Preferably, the sidewall of the sealing seat is covered with an airbag protective pad.

[0022] After adopting the above technical solution, it should be noted that the airbag protective pad has good elastic cushioning performance. When the sealing seat descends and closes with the discharge port, its elasticity can prevent the sealing seat from making hard contact with the inner wall of the discharge port, reducing component wear. More importantly, for fertilizer that is in the gap of the discharge port and has not yet completely fallen, the airbag protective pad will form a flexible wrapping rather than rigid compression, effectively preventing the squeezing force of the sealing seat at the moment of closure from pressing the fertilizer into clumps, ensuring that the fertilizer particles remain in a loose state, which is convenient for subsequent spraying and mixing.

[0023] Preferably, the bottom of the second chamber is connected to a discharge port, and a solenoid valve is installed in the discharge port.

[0024] After adopting the above technical solution, it should be noted that the solenoid valve is used to open and close the discharge port.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0026] 1. In this invention, the separate design of the first and second compartments separates the storage and processing functions, improving operational flexibility; the constriction structure of the discharge port and the cooperation of the sealing seat ensure effective control of the discharge, preventing leakage; the double spray head design of the first and second spray heads allows the anti-caking agent to fully coat the fertilizer, significantly improving the anti-caking effect and extending the fertilizer storage time; the lifting device drives the sealing seat to rise and fall, allowing the discharge port to open or close. Furthermore, if intermittent discharge is required, the lifting device can drive the sealing seat to rise and fall intermittently, achieving intermittent discharge and intermittent spraying. This intermittent spraying method not only saves on the amount of anti-caking agent used but also allows for more sufficient contact time between the fertilizer and the anti-caking agent (because during continuous discharge, the fertilizer falling later pushes the preceding fertilizer through the spraying area quickly, and the particles only stay in the spray for a moment).

[0027] 2. In this invention, by setting a piston plate and a piston column, the device uses the pressure of the anti-caking agent itself to drive the piston plate to move, thereby achieving the function of raising or lowering the sealing seat without the need for an additional power source; and the integrated design of the lifting device and the anti-caking agent conveying system enables the feeding and spraying actions to work together, improving the integration and working efficiency of the device.

[0028] 3. In this invention, the setting of the stirring rod effectively solves the problem that fertilizer is easy to condense in the storage bin, resulting in poor material discharge, and ensures that the fertilizer can fall smoothly; the linkage device cleverly combines the lifting and rotating action of the piston column, so that the stirring action of the stirring rod and the lifting action of the sealing seat are synchronized, without the need to set up an additional power source to drive the stirring rod.

[0029] 4. In this invention, the design of the first spray head with the spray tip tilted upward and the second spray head with the spray tip tilted downward has the core advantage of significantly increasing the fog coverage and three-dimensional space through complementary directions, thereby improving the contact efficiency between the anti-caking agent and the fertilizer.

[0046] Example

[0047] like Figures 1-8As shown in the figure, an embodiment of the present invention discloses an organic fertilizer transportation device, including a first conveyor 200. A storage silo 100 is supported above the first conveyor 200 by a bracket 101. The storage silo 100 includes a first silo body 107 and a second silo body 102. The bottom of the first silo body 107 has a discharge port with a diameter that gradually decreases from top to bottom. A sealing seat 103 is provided inside the discharge port, and the sidewall of the sealing seat 103 is adapted to the bottom shape of the inner wall of the discharge port. The second silo body 102 is located below the first silo body 107, and the bottom of the discharge port is inserted into the second silo body 102. The second silo body 102 is provided with a means for... The lifting device of the lifting sealing seat 103; a housing 104 is also fixed inside the second chamber 102. Several liquid outlets 1041 are provided circumferentially through the side wall of the housing 104. Each liquid outlet 1041 is connected to a first spray head 1044. The housing 104 is connected to an external pressure pump 201 through a first water pipe 202. An annular pipe 105 is provided on the inner wall of the second chamber 102. The annular pipe 105 is connected to the first water pipe 202 through a second water pipe 203. Several second spray heads 106 are connected to the annular pipe 105. The side wall of the sealing seat 103 is located between the first spray head 1044 and the second spray head 106. It should be noted that the first conveyor 200 is used to receive and transport fertilizer falling from each storage bin 100; the storage bin 100 is used to classify and store fertilizer, and the first bin 107 serves as the main storage space for fertilizer, used to hold a large amount of fertilizer to be used; the diameter of the discharge port gradually decreases from top to bottom, forming a tapering structure, which facilitates the concentrated falling of fertilizer and prevents fertilizer from accumulating at the outlet; the sealing seat 103 is adapted to the shape of the inner wall of the discharge port, and controls the flow of fertilizer in the first bin 107 by fitting and separating from the discharge port; the second bin 102 is the area for fertilizer discharge and anti-caking treatment, providing installation space for components such as the lifting device and spray structure; the lifting device drives the sealing seat 103 to rise and fall, realizing intermittent control of the discharge; The housing 104 provides a mounting carrier for part of the lifting device structure, while the liquid outlet 1041 on its side wall provides a channel for the anti-caking agent to be sprayed out. The first spray head 1044 and the second spray head 106 spray the falling fertilizer with anti-caking agent from the inside and outside of the fertilizer, respectively, to ensure uniform spraying. The annular pipe 105 enables the second spray head 106 to be evenly distributed around the second chamber 102, achieving all-round spraying. The first water pipe 202 and the second water pipe 203 provide a conveying channel for the anti-caking agent, conveying the anti-caking agent pressurized by the pressure pump 201 to the housing 104 and the annular pipe 105, respectively. The pressure pump 201 provides power for the conveying of the anti-caking agent, ensuring that the anti-caking agent can be sprayed out from the spray head at a certain pressure. In the initial state, the sealing seat 103 is in contact with the bottom inner wall of the discharge port of the first chamber 107, blocking the fertilizer from falling.During operation, the pressure pump 201 is started. The pressure pump 201 pressurizes the external anti-caking agent and splits it into two streams through the first water pipe 202. One stream is sent into the housing 104, and the other stream is sent into the annular pipe 105 through the second water pipe 203. The anti-caking agent entering the housing 104 pushes the lifting device to move, causing the sealing seat 103 to rise. A gap is formed between the sealing seat 103 and the discharge port, allowing the fertilizer in the first chamber 107 to fall into the second chamber 102 through the gap. Simultaneously, the anti-caking agent inside the housing 104 is sprayed out from the liquid outlet 1041 through the first spray head 1044 under pressure, and then into the annular pipe. The anti-caking agent inside 105 is sprayed out through the second spray head 106. Since the side wall of the sealing seat 103 is located between the two spray heads, the falling fertilizer will be sprayed by the inner first spray head 1044 and the outer second spray head 106 at the same time, and the anti-caking agent will be evenly coated on the surface of the fertilizer particles. When it is necessary to stop feeding, the pressure pump 201 will extract the anti-caking agent from the housing 104, and the lifting device will drive the sealing seat 103 to descend and re-fit with the discharge port, blocking the feeding. The first spray head 1044 and the second spray head 106 will also stop spraying, forming a cycle of intermittent feeding and intermittent spraying. In this design, the separate design of the first compartment 107 and the second compartment 102 separates the storage and processing functions, improving operational flexibility. The closing structure of the discharge port and the cooperation of the sealing seat 103 ensure effective control of the discharge and prevent leakage. The double spray head setup of the first spray head 1044 and the second spray head 106 allows the anti-caking agent to fully coat the fertilizer, significantly improving the anti-caking effect and extending the fertilizer storage time. The lifting device drives the sealing seat 103 to rise and fall, which can open or close the discharge port. At the same time, if intermittent discharge is required, the lifting device can drive the sealing seat 103 to rise and fall intermittently, realizing intermittent discharge and intermittent spraying. This intermittent spraying method not only saves the amount of anti-caking agent, but also allows the fertilizer and anti-caking agent to have more contact time (because when continuously discharging, the fertilizer falling later will push the fertilizer falling earlier to quickly pass through the spraying area, and the particles only stay in the spray for a moment).

[0048] like Figures 4-5As shown, in this embodiment, the lifting device includes a piston plate 1034 and a piston rod 1033. The piston plate 1034 is slidably embedded in the housing 104. The piston plate 1034 divides the interior of the housing 104 into an upper cavity 1042 and a lower cavity 1043. The first water pipe 202 is connected to the lower cavity 1043. In the initial state, the liquid outlet 1041 is located in the upper cavity 1042. One end of the piston rod 1033 is connected to the piston plate 1034, and the other end passes through the top of the housing 104 and is connected to the bottom of the sealing seat 103. It should be noted that the piston plate 1034 slides within the housing 104, causing the piston column 1033 to rise and fall, thus dividing the housing 104 into two independent chambers for pressure control. The piston column 1033, acting as a force transmission component, converts the linear motion of the piston plate 1034 into the rising and falling motion of the sealing seat 103, connecting the piston plate 1034 and the sealing seat 103. The first water pipe 202 is connected to the lower chamber 1043, providing a channel for the anti-caking agent to enter the lower chamber 1043, and uses fluid pressure to drive the piston plate 1034. Initially, the pressure inside the lower chamber 1043 is low, the piston plate 1034 is in a low position, and the piston column 1033 causes the sealing seat 103 to fit against the outlet. The liquid outlet 1041 is located inside the upper chamber 1042, and there is no pressure difference between the upper chamber 1042 and the outside, so the spray head does not spray liquid. When material needs to be discharged, the pressure pump 201 pumps the anti-caking agent into the lower chamber 1043, increasing the pressure inside the lower chamber 1043 and pushing the piston plate 1034 to slide upward. The piston plate 1034 drives the piston column 1033 to rise synchronously, and the piston column 1033 pushes the sealing seat 103 to rise, creating a gap between the sealing seat 103 and the discharge port, and the fertilizer begins to fall. As the piston plate 1034 continues to rise, when the piston plate 1034 moves above the position where the upper chamber 1042 connects with the liquid outlet 1041, the anti-caking agent enters the liquid outlet 1041, and the liquid outlet 1041 forms a passage with the outside, allowing the anti-caking agent to be sprayed out from the first spray head 1044, thus achieving spraying. When it needs to be stopped, the pressure pump 201 extracts the anti-caking agent from the lower chamber 1043, reducing the pressure inside the lower chamber 1043. The piston plate 1034 descends under its own weight and the fertilizer pressure, and the piston column 1033 drives the sealing seat 103 to reset. The piston plate 1034 returns to its initial position, and the liquid outlet 1041 re-enters the upper chamber 1042, stopping the spraying and interrupting the feeding. In this design, by setting up the piston plate 1034 and piston column 1033, the device utilizes the pressure of the anti-caking agent itself to drive the piston plate 1034, thereby achieving the function of raising or lowering the sealing seat 103, without the need for an additional power source. Furthermore, the integrated design of the lifting device and the anti-caking agent conveying system allows the feeding and spraying actions to coordinate, improving the integration and working efficiency of the device.

[0049] As shown in Figure 6, in this embodiment, the top of the sealing seat 103 is provided with a stirring rod 1031; the bottom of the piston rod 1033 is rotatably connected to the piston plate 1034, and the piston rod 1033 is movably connected to the top of the housing 104. A linkage device is also provided inside the housing, which can drive the piston rod 1033 to rotate when the piston rod 1033 rises or falls. The stirring rod 1031 is provided with stirring blades 1032, which are perpendicular to the stirring rod 1031. It should be noted that the stirring rod 1031 is used to disperse the fertilizer that has clumped together at and near the discharge port of the first chamber 107, so as to prevent the fertilizer from clumping and causing blockage during discharge; the piston rod 1033 has both lifting and rotating functions, which can both drive the sealing seat 103 to lift and control the discharge, and drive the sealing seat 103 to rotate so that the stirring rod 1031 can play its role. Its rotational connection with the piston plate 1034 ensures that the linear sliding of the piston plate 1034 is not affected during rotation, and the movable connection with the top of the housing 104 provides flexible space for lifting and rotation; the linkage device converts the axial movement of the piston rod 1033 into circumferential rotational motion. When the pressure pump 201 supplies pressure to the housing 104, pushing the piston plate 1034 upward, the piston plate 1034 drives the piston column 1033 to rise synchronously. During the rising process, the linkage device inside the housing 104 generates a circumferential force on the piston column 1033. Since the bottom of the piston column 1033 is rotatably connected to the piston plate 1034 and the top is movably connected to the housing 104, the piston column 1033 rotates while rising. The rotation of the piston column 1033 drives the sealing seat 103 to rotate synchronously. The stirring rod 1031 at the top of the sealing seat 103 rotates with the sealing seat 103, stirring and dispersing the fertilizer that has condensed at the discharge port of the first chamber 107 and during the falling process. When the pressure pump 201 pumps liquid and causes the piston plate 1034 to fall, the piston column 1033 falls with the piston plate 1034. The linkage device also drives the piston column 1033 to rotate in the opposite direction. The stirring rod 1031 continues to rotate, further cleaning up the remaining clumps of fertilizer until the sealing seat 103 is in contact with the discharge port, and the feeding stops. In this solution, the setting of the stirring rod 1031 effectively solves the problem that fertilizer is easy to condense in the storage bin 100, resulting in poor material discharge, and ensures that the fertilizer can fall smoothly; the linkage device cleverly combines the lifting and rotating action of the piston rod 1033, so that the stirring action of the stirring rod 1031 and the lifting action of the sealing seat 103 are synchronized, without the need to set up an additional power source to drive the stirring rod 1031.

[0050] like Figure 8As shown, in this embodiment, the piston rod 1033 has an arc-shaped groove 10331 on its side wall, the arc-shaped groove 10331 having a higher end and a lower end; the linkage device includes a guide rod 10332, one end of the guide rod 10332 being connected to the inner wall of the housing 104, and the other end being slidably embedded in the arc-shaped groove 10331. It should be noted that the arc-shaped groove 10331 is the core structure for force conversion. Through the difference in height between its upper and lower ends, it converts the fixed support of the guide rod 10332 into a circumferential force that drives the piston rod 1033 to rotate. One end of the guide rod 10332 is fixed to the inner wall of the housing 104, providing a fixed support point for the movement of the piston rod 1033. The other end is embedded in the arc-shaped groove 10331 and slides along the arc-shaped groove 10331 when the piston rod 1033 rises and falls, while generating a reaction force on the arc-shaped groove 10331. The setting of the higher and lower ends creates a slope in the arc-shaped groove 10331, providing a basis for the sliding of the guide rod 10332 and the transmission of force. When the piston rod 1033 rises under the action of the piston plate 1034, the guide rod 10332 embedded in the arc-shaped groove 10331 remains fixed in position. The rise of the piston rod 1033 causes the arc-shaped groove 10331 to slide relative to the guide rod 10332, and the end of the guide rod 10332 moves from the higher end to the lower end of the arc-shaped groove 10331. Since the arc-shaped groove 10331 is curved, the guide rod 10332 generates a lateral thrust on the side wall of the arc-shaped groove 10331, pushing the piston rod 1033 to rotate around its own axis. When the piston rod 1033 falls, the end of the guide rod 10332 slides from the lower end to the higher end of the arc-shaped groove 10331, similarly generating a reverse lateral thrust on the arc-shaped groove 10331, causing the piston rod 1033 to rotate in the opposite direction. Throughout the process, the guide rod 10332 remains embedded in the arc-shaped groove 10331, ensuring continuous and stable force transmission.

[0051] In this embodiment, the spray tip of the first spray head 1044 is tilted upwards, and the spray tip of the second spray head 106 is tilted downwards. It should be noted that the design of the first spray head 1044 tilting upwards and the second spray head 106 tilting downwards has the core advantage of significantly increasing the fog coverage and three-dimensional space through complementary directions, thereby improving the contact efficiency between the anti-caking agent and the fertilizer. When the first spray head 1044 sprays upwards at an angle, the anti-caking agent mist diffuses upwards along the tilt direction, overcoming the limitations of horizontal spraying and covering the upper and middle areas of the second chamber 102, especially targeting fertilizer particles at a higher position during the initial stage of falling from the outlet gap. When the second spray head 106 sprays downwards at an angle, the mist extends downwards to the lower and middle parts of the second chamber 102, forming a vertical connection with the mist from the first spray head 1044. The mists from the two spray heads converge and merge inside the second chamber 102, forming a three-dimensional fog curtain extending from top to bottom, rather than a single planar fog layer. This three-dimensional fog screen not only expands the horizontal coverage width but also increases the vertical coverage height. When fertilizer particles slide down the conical top of the sealing seat 103 and diverge through the second chamber 102, they will travel through this three-dimensional fog screen throughout the entire process. No matter which stage the particles are in on the falling trajectory, they can fully contact the anti-caking agent droplets.

[0052] like Figures 4-5 As shown, in this embodiment, the top of the sealing seat 103 has a conical structure. It should be noted that when the fertilizer in the first compartment 107 falls, the conical surface can guide the fertilizer to slide quickly towards the edge of the sealing seat 103, avoiding fertilizer accumulation and residue on the top of the sealing seat 103 and reducing the risk of clumping.

[0053] In another embodiment, there are multiple storage bins 100, which are spaced apart along the length of the first conveyor 200. It should be noted that the multiple storage bins 100 can store basic fertilizers such as nitrogen, phosphorus, and potassium, as well as different component materials such as micronutrients and synergists, achieving classified storage and precise quantity control. With their spaced arrangement along the first conveyor 200 and the intermittent feeding function of the storage bins 100, different fertilizer components will fall into the conveyor in batches and in an orderly manner, rather than accumulating in large quantities simultaneously. This "staggered feeding" allows the agitator in the subsequent mixing bin more time to mix the components evenly, ensuring uniform nutrient content in the compound fertilizer.

[0054] In another embodiment, the sidewall of the sealing seat 103 is covered with an airbag protective pad. It should be noted that the airbag protective pad has good elastic cushioning performance. When the sealing seat 103 descends and closes with the discharge port, its elasticity can prevent the sealing seat 103 from making hard contact with the inner wall of the discharge port, reducing component wear. More importantly, for fertilizer that is in the gap of the discharge port and has not yet completely fallen, the airbag protective pad will form a flexible wrapping rather than rigid compression, effectively preventing the squeezing force of the sealing seat 103 at the moment of closure from compressing the fertilizer into clumps, ensuring that the fertilizer particles remain in a loose state, which is convenient for subsequent spraying and mixing.

[0055] In another embodiment, the bottom of the second chamber 102 is connected to a discharge port, and a solenoid valve is provided in the discharge port. It should be noted that the solenoid valve is used to open and close the discharge port.

[0056] The working principle of this invention is as follows:

[0057] In the initial working state of the organic fertilizer transport device, multiple storage bins 100, spaced apart along the length of the first conveyor 200, are all in a closed state. The discharge port of the first bin 107 of each storage bin 100 is tightly sealed by the sealing seat 103. The conical structure at the top of the sealing seat 103 is kept clean, and the airbag protective pad covering the side wall has no gap with the inner wall of the discharge port. The stirring rod 1031 at the top of the sealing seat 103 is stationary. The shell inside the second bin 102 of the storage bin 100... There is no pressure in the lower cavity 1043 of body 104, and the piston plate 1034 is in a low position, so that the liquid outlet 1041 on the side wall of the housing 104 is in the upper cavity 1042. The first spray head 1044 does not spray liquid temporarily, and there is no anti-caking agent flowing in the second water pipe 203 and the annular pipe 105 connected to the first water pipe 202. The second spray head 106 is also in a standby state. The solenoid valve in the discharge port at the bottom of the second chamber 102 remains closed, and the first conveyor 200 is in a standby state.After starting the device, the external pressure pump 201 is started first. The pressure pump 201 pressurizes the external anti-caking agent and delivers it through the first water pipe 202. One anti-caking agent is continuously introduced into the lower cavity 1043 of the shell 104 of the second silo body 102 of each storage silo 100, so that the pressure in the lower cavity 1043 gradually increases and pushes the piston plate 1034 to slide upward. The piston plate 1034 drives the piston column 1033 connected to it to rise synchronously. During the rise of the piston column 1033, the guide rod 10332 embedded in the arc groove 10331 on its side wall is fixed in position because it is fixed to the inner wall of the shell 104. When the arc groove 10331 slides along the guide rod 10332, the guide rod 10332 generates a lateral thrust on the side wall of the arc groove 10331, which drives the piston column 10334 to rise. 33 rotates around its own axis, and the sealing seat 103 connected to the top of the piston column 1033 rises and rotates synchronously with the piston column 1033. The stirring rod 1031 at the top of the sealing seat 103 rotates accordingly, stirring and dispersing the fertilizer that has condensed at and near the discharge port of the first chamber 107. When the sealing seat 103 rises to form a gap with the inner wall of the discharge port of the first chamber 107, the fertilizer in the first chamber 107 slides down along the conical top of the sealing seat 103 under the action of gravity and falls into the second chamber 102 through the gap. At the same time, after the piston plate 1034 continues to rise to the position of the liquid outlet 1041 that passes the side wall of the shell 104, the anti-caking agent in the lower cavity 1043 enters the upper cavity 1042 of the shell 104 and is sprayed from the liquid outlet 1041 through the first spray head 1044. The first spray head 1044, with its upward-sloping spray tip, causes the anti-caking agent mist to diffuse upwards to the upper part of the second chamber 102. Another stream of anti-caking agent flows through the second water pipe 203 into the annular pipe 105 on the inner wall of the second chamber 102, and then is sprayed out through the downward-sloping second spray head 106 on the annular pipe 105. The mist extends downwards to the lower part of the second chamber 102. The mists from the two spray heads converge and merge inside the second chamber 102, forming a three-dimensional mist curtain. Because the side wall of the sealing seat 103 is located between the two spray heads, the falling fertilizer will pass through the three-dimensional mist curtain throughout its journey and be evenly coated with the anti-caking agent. After each storage chamber 100 completes a batch of material feeding according to the preset ratio, the pressure pump 201 stops supplying pressure and extracts the anti-caking agent from the housing 104, and the lower chamber 1... As the internal pressure of 043 decreases, the piston plate 1034 descends under its own weight and fertilizer pressure, causing the piston column 1033 and the sealing seat 103 to descend synchronously and rotate in the opposite direction. The stirring rod 1031 continues to rotate to clean up residual clumps until the sealing seat 103 re-fits the discharge port of the first chamber 107. The airbag protective pad forms a flexible wrap around the fertilizer that has not completely fallen at the discharge port gap to prevent it from being squeezed and clumped. At this time, the piston plate 1034 returns to its initial position, causing the first spray head 1044 to stop spraying liquid. The anti-caking agent conveying in the annular pipe 105 also stops synchronously, forming a cycle of intermittent feeding and intermittent spraying. Subsequently, the solenoid valve in the discharge port at the bottom of the second chamber 102 opens, and the fertilizer treated with anti-caking agent falls into the first conveyor 200 below through the discharge port.
