Description

Technical Field

[0001] This invention relates to the field of organic fertilizer preparation technology, specifically to a mixture formed by an organic fertilizer and a coating agent with no special fertilizer effect through a coating machine. Background Technology

[0002] Organic fertilizers are mainly derived from animal and plant residues or metabolites. They are natural fertilizers rich in organic matter and various nutrients, produced through decomposition and fermentation. They can improve soil structure, enhance fertility, and promote crop growth.

[0003] The coating machine's tank rotates circumferentially, causing the organic fertilizer granules inside to tumble, collide, and mix. This ensures that the surface of the organic fertilizer granules is evenly contacted with the coating agent sprayed from inside the tank, forming a uniform and dense coating layer on the surface of the organic fertilizer granules. The coating agent contains no special fertilizer-enhancing components; it is only used to coat the fertilizer granules, achieve slow release, and prevent clumping, and does not contribute to fertilizer efficacy.

[0004] A search revealed that patent CN219839649U, entitled "An Organic Fertilizer Coating Machine," effectively solves the problem of fertilizer clumping and impurities affecting coating by setting up a breaking unit and a feeding unit. However, this coating machine does not disclose or involve the control of the coating agent spraying volume. In actual use, the spraying volume of its nozzles is usually fixed or relies on manual adjustment. The limitations of this adjustment method are: a fixed spraying volume cannot be dynamically adjusted according to the actual amount of fertilizer loaded in the tank, resulting in overspraying and waste when the amount of fertilizer is small, and underspraying when the amount of fertilizer is large, affecting the uniformity and efficiency of coating; relying on manual adjustment not only increases the burden on operators, but also makes it difficult to achieve real-time and accurate control of the coating agent flow rate. It is easy for the coating agent to be used uneconomically or the coating quality to be unstable due to adjustment lag or human error, thus restricting the automation level and production efficiency of the equipment.

[0005] A search revealed that patent CN206127160U proposes a "fertilizer coating machine," which improves the spraying range and uniformity through multiple spray pipes and conical nozzles. However, during long-term operation, dust from the working environment easily adheres to the surface of the nozzles. This dust combines with and solidifies with the residue of the atomized coating agent, forming blockages in and around the nozzle holes. This process not only gradually reduces spraying efficiency and disrupts coating uniformity but also significantly increases the equipment's maintenance burden, requiring shutdowns for manual cleaning during production, severely restricting the equipment's continuous operation stability and economic efficiency. Summary of the Invention

[0006] The purpose of this invention is to address the problem in the prior art where a fixed spraying rate cannot be dynamically adjusted according to the actual fertilizer loading in the tank. This leads to overspraying and waste when the fertilizer quantity is small, and underspraying when the fertilizer quantity is large, affecting the uniformity and efficiency of the coating. Furthermore, dust / dust mixes and solidifies with the residue of the atomized coating agent, forming blockages in and around the spray nozzles. This process not only gradually reduces spraying efficiency and damages coating uniformity, but also significantly increases the maintenance burden on the equipment, requiring shutdowns for manual cleaning during production, severely restricting the stability and economy of continuous equipment operation. The proposed invention provides an organic fertilizer coating machine with an integrated mixing and impurity removal structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an organic fertilizer coating machine with an integrated mixing and impurity removal structure, the coating machine comprising a base and a tank, the tank being installed on top of the base, and the tank having an internal dynamic adjustment structure for the spraying amount of coating agent, the dynamic adjustment structure comprising a rectangular spray pipe disposed inside the tank, the spray pipe being equipped with a nozzle, the base being fixed to the spray pipe by a support rod, a vertical plate being fixed to the side of the spray pipe, the vertical plate having a sliding groove, and a slider being slidably connected inside the sliding groove, the bottom of the vertical plate being provided with a... A first spring is connected to a slider, which is fixed with a receiving plate. A baffle is slidably connected inside the spray pipe, and the baffle is connected to the inside of the spray pipe by a second spring. A pull rope is fixed to the baffle, and one end of the pull rope passes through a vertical plate and is fixedly connected to the slider. A delay structure is provided at the bottom of the inner cavity of the spray pipe. The delay structure is used to delay the reset time of the dynamic adjustment structure. The delay structure is linked to a dust removal structure and a spray expansion structure. The dust removal structure is used to remove dust from the outside of the nozzle to prevent clogging, and the spray expansion structure is used to expand the spray range of the nozzle.

[0008] As a further embodiment of the present invention, a storage box is installed at the bottom of the base for storing the coating agent. The storage box is equipped with a pump, which is connected to a delivery pipe. One end of the delivery pipe is located inside the storage box, and the other end of the delivery pipe passes through the inside of the support rod and then into the inside of the spray pipe.

[0009] As a further embodiment of the present invention, the delay structure includes a first groove at the bottom of the inner cavity of the spray pipe, a first wedge block made of magnet is slidably connected in the first groove, the first wedge block is fixedly connected to the baffle, one side of the first groove is a second groove, a second wedge block is slidably connected in the second groove, and the interior of the second groove is connected to the second wedge block by a third spring.

[0010] As a further embodiment of the present invention, the dust removal structure includes a hollow box fixed to the outside of the spray pipe, a piston slidably connected inside the hollow box, a connecting rod fixed to the first wedge block, and one end of the connecting rod passing through the side wall of the spray pipe and being fixedly connected to the piston.

[0011] As a further embodiment of the present invention, the dust removal structure also includes an exhaust pipe connected to the bottom of the hollow box. The inner wall of the exhaust pipe is provided with a first spiral groove, one end of the exhaust pipe is located at the nozzle and connected to a conical nozzle, and the outer wall of the nozzle is provided with a second spiral groove.

[0012] As a further embodiment of the present invention, the spray expansion structure includes a first limiting groove at the bottom of the spray pipe, and an iron plate is slidably connected to the bottom of the spray pipe along the first limiting groove. The iron plate is fixed with a first rack and a first arc-shaped baffle.

[0013] As a further embodiment of the present invention, the spray expansion structure further includes a second limiting groove at the bottom of the spray pipe, and a second rack is slidably connected to the bottom of the spray pipe along the second limiting groove. A gear is rotatably connected to the bottom of the spray pipe, and the gear meshes with both the first rack and the second rack. A second arc-shaped baffle is fixed to the second rack.

[0014] As a further embodiment of the present invention, the inner wall of the tank is arrayed with horizontal stripes.

[0015] As a further embodiment of the present invention, the tank body achieves the purpose of mixing / blending organic fertilizer and thus coating, and removes dust and other impurities from the nozzle through a dust removal structure, thereby realizing an integrated structural design of mixing / blending and impurity removal.

[0016] The working process of the tank is as follows:

[0017] Step 1: Put the organic fertilizer into the tank and start the rotation. The horizontal bar lifts and throws the fertilizer. If the amount of fertilizer is small, the impact force when it falls to the receiving plate is small. The baffle keeps the nozzle partially covered. At this time, the spray volume is low. The No. 1 arc baffle and the No. 2 arc baffle are brought together to limit the spray range.

[0018] Step 2: As the amount of fertilizer in the tank increases, the falling material impacts the receiving plate, generating an impact force that pushes the slider downward. Pulling the rope moves the baffle to reduce obstruction of the nozzle, thereby increasing the flow rate of the coating agent sprayed from the nozzle and achieving adaptive adjustment of the spraying volume.

[0019] Step 3: When the baffle moves, it drives the first wedge block to move and misaligns with the second wedge block to form a delay. At the same time, the connecting rod pushes the piston in the hollow box, compresses the gas and forms a swirling flow through the first spiral groove, and then the gas is gathered through the conical nozzle and sprayed out to clean the surface of the nozzle.

[0020] Step 4: When the first wedge block made of magnet moves, it attracts the iron plate, and then drives the first rack through the gear to the second rack, so that the opening between the first arc-shaped baffle and the second arc-shaped baffle expands the spray range.

[0021] The organic fertilizer coating machine with an integrated mixing and impurity removal structure proposed in this invention has the following advantages:

[0022] 1. Traditional coating machines in the background art rely on fixed spray volumes or manual adjustment, which cannot adjust the spray volume in real time and accurately according to the fertilizer load in the tank, easily leading to waste of coating agent or uneven coating. This invention addresses this problem by setting up a dynamic adjustment structure composed of a receiving plate, slider, pull rope, and baffle. It utilizes the impact force of fertilizer being thrown onto the receiving plate to automatically sense and respond to changes in the amount of fertilizer in the tank, thereby controlling the baffle to adjust the nozzle opening and achieving dynamic matching between the coating agent spray volume and the fertilizer volume. This mechanical feedback mechanism requires no external control or manual intervention, not only solving the problems of insufficient or excessive spraying and improving coating uniformity and fertilizer quality, but also significantly improving the automation level of the equipment and reducing operational burden and production costs.

[0023] 2. Addressing the problem in the background technology where long-term operation of the spray nozzles easily leads to clogging due to the fusion of dust and coating agent residues, resulting in decreased spraying efficiency and frequent maintenance, this invention utilizes a delayed-structure linked dust removal structure. A moving baffle drives a piston to generate airflow, which, through a spiral groove and a conical nozzle, forms a high-speed swirling flow. This periodically and automatically sweeps the nozzle surface, effectively preventing dust from solidifying and clogging, ensuring the stability and continuity of spraying, and reducing downtime for maintenance. Simultaneously, through magnetic linkage and rack and pinion transmission, the spray expansion structure automatically adjusts the opening and closing width of the two arc-shaped baffles according to changes in fertilizer quantity, dynamically altering the effective spraying range of the nozzle. This minimizes diffusion and waste when fertilizer quantity is low, and expands coverage to ensure adequate coating when fertilizer quantity is high, further enhancing the equipment's adaptability to different fertilizer production conditions and optimizing the overall coating effect.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," "linked," and "set up" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. The following describes embodiments of the invention based on its overall structure.

[0041] An organic fertilizer coating machine with an integrated mixing and impurity removal structure includes: a base 1 and a tank 2. The inner wall of the tank 2 is arranged with horizontal bars 37. The tank 2 is installed on the top of the base 1. The interior of the tank 2 is provided with a dynamic adjustment structure for the spraying amount of coating agent.

[0042] Furthermore, the dynamic adjustment structure includes a rectangular spray pipe 3 installed inside the tank body 2, the spray pipe 3 is equipped with a nozzle 10, the base 1 is fixed to the spray pipe 3 by a support rod 4, a vertical plate 5 is fixed to the side of the spray pipe 3, the vertical plate 5 is provided with a sliding groove 6, and a slider 7 is slidably connected inside the sliding groove 6. The bottom of the vertical plate 5 is connected to the slider 7 by a first spring 8, the slider 7 is fixed with a receiving plate 9, a baffle 11 is slidably connected inside the spray pipe 3, the baffle 11 is connected to the inside of the spray pipe 3 by a second spring 12, a pull rope 13 is fixed to the baffle 11, and one end of the pull rope 13 passes through the vertical plate 5 and is fixedly connected to the slider 7.

[0043] In addition, a storage box 14 is installed at the bottom of the base 1. The storage box 14 is used to store the coating agent. The storage box 14 is equipped with a pump 15. The pump 15 is connected to a delivery pipe 16. One end of the delivery pipe 16 is located inside the storage box 14, and the other end of the delivery pipe 16 passes through the inside of the support rod 4 and then enters the inside of the spray pipe 3.

[0044] The working principle described above is as follows: the coating agent in storage tank 14 is pumped through pump 15 and delivery pipe 16 to the interior of spray pipe 3; during operation, organic fertilizer enters the interior of tank 2, such as... Figure 6 As shown, at this time, the baffle 11 partially blocks the nozzle 10, reducing the opening. This state is suitable for situations where the amount of fertilizer in the tank 2 is small.

[0045] The tank 2 rotates, causing the horizontal bar 37 to rotate as well. The horizontal bar 37 carries the fertilizer upward along the inner wall of the tank 2 and then throws it down. The falling fertilizer reaches the top of the receiving plate 9. As the amount of fertilizer loaded in the tank 2 increases, the mass and impact force of the fertilizer lifted by the horizontal bar 37 and thrown onto the receiving plate 9 per unit time also increase, thus applying a downward force to the receiving plate 9. This force can overcome the resistance of the first spring 8 to the slider 7. Then, the slider 7 descends inside the slide 6 and compresses the first spring 8. After that, the slider 7 descends and pulls the pull rope 13 simultaneously. By pulling the pull rope 13, the baffle 11 slides along the bottom of the inner cavity of the spray pipe 3, gradually reducing its obstruction area on the liquid inlet channel of the nozzle 10. This increases the flow cross section of the coating agent, thereby increasing the spray flow rate. The nozzle 10, which is initially half-open, is gradually opened to increase the liquid inlet. The degree to which the nozzle 10 is opened is proportional to the amount of fertilizer in the tank 2.

[0046] Additionally, when the amount of fertilizer in tank 2 is small, it will also fall onto the receiving plate 9. However, because the weight on the receiving plate 9 is low, it cannot overcome the resistance of spring 8, so the receiving plate 9 will remain stationary. Consequently, the receiving plate 9 will only receive feedback when the amount of fertilizer increases.

[0047] As described above, the mechanical feedback from the receiving plate 9 allows for real-time sensing of changes in the amount of fertilizer in the tank 2, automatically adjusting the opening of the nozzle 10 to precisely control the spray flow rate of the coating agent. This not only avoids the waste or insufficient spraying of the coating agent caused by traditional fixed spraying or manual adjustment methods, significantly improving coating uniformity and fertilizer coating quality, but also greatly reduces the burden of manual operation, enhances the automation of equipment operation, and helps improve production efficiency and economic benefits.

[0048] Specifically, a delay structure is provided at the bottom of the inner cavity of the spray pipe 3, which is used to delay the reset time of the dynamic adjustment structure.

[0049] Furthermore, the delay structure includes a first groove 17 at the bottom of the inner cavity of the spray pipe 3, a first wedge block 18 made of magnet is slidably connected in the first groove 17, the first wedge block 18 is fixedly connected to the baffle 11, one side of the first groove 17 is a second groove 19, a second wedge block 20 is slidably connected in the second groove 19, and the interior of the second groove 19 is connected to the second wedge block 20 by a third spring 36.

[0050] The working principle described above is as follows: Figure 8 As shown, at this time, the lower inclined surface of the first wedge block 18 is in contact with the upper inclined surface of the second wedge block 20. Both the lower inclined surface of the first wedge block 18 and the upper inclined surface of the second wedge block 20 are smooth to reduce the friction when the two surfaces are in contact. However, both the upper inclined surface of the first wedge block 18 and the lower inclined surface of the second wedge block 20 are rough to increase the friction when the two surfaces are in contact and thus delay the contact.

[0051] When the baffle 11 moves, it will move the first wedge block 18 in the first groove 17. Due to the large mass and impact force of the fertilizer thrown onto the receiving plate 9, the lower inclined surface of the first wedge block 18 will easily pass through the upper inclined surface of the second wedge block 20. During this process, the second wedge block 20 will retreat in the second groove 19 and compress the third spring 36. When the first wedge block 18 has completely passed through, the third spring 36 will reset. At this time, the first wedge block 18 and the second wedge block 20 will be misaligned.

[0052] Then, when the impact force applied to the fertilizer receiving plate 9 disappears, the receiving plate 9 is lifted and reset by the first spring 8, and the pull rope 13 is released from the tensioned state. Then, the second spring 12 lifts the baffle 11 back to its original position. During the resetting process, the baffle 11 needs to overcome the friction between the upper inclined surface of the first wedge block 18 and the lower inclined surface of the second wedge block 20. At the same time, the baffle 11 needs to overcome the resistance applied to the second wedge block 20 by the third spring 36 during the resetting process. Therefore, the baffle 11 moves very quickly when pulled by the pull rope 13, but the speed is significantly reduced during the resetting process, thus achieving a delay.

[0053] The purpose of the aforementioned delay is to provide a reasonable holding time for the delay structure after the receiving plate 9 has been subjected to a single impact from the falling material, so as to prevent the opening of the nozzle 10 from immediately reverting as the receiving plate 9 instantly resets.

[0054] Specifically, this function is described as follows: When the tank 2 rotates, the fertilizer does not fall continuously and evenly onto the receiving plate 9, but is periodically lifted and scattered as the tank 2 rotates. If there is no delay, the receiving plate 9 will quickly reset after a single impact, and the baffle 11 will quickly move in the opposite direction under the restoring force of the second spring 12, thereby re-blocking the liquid inlet channel of the nozzle 10. This causes its opening to decrease rapidly during the fertilizer scattering intervals, and the spray flow rate to drop sharply, making it difficult to form a uniform coating layer, thus affecting the coating efficiency and quality stability.

[0055] Specifically, the delay structure is linked to a dust removal structure, which is used to remove dust from the outside of the nozzle 10 to prevent clogging.

[0056] Furthermore, the dust removal structure includes a hollow box 21 fixed to the outside of the spray pipe 3, a piston 22 slidably connected inside the hollow box 21, a connecting rod 23 fixed to the first wedge block 18, and one end of the connecting rod 23 passing through the side wall of the spray pipe 3 and being fixedly connected to the piston 22.

[0057] Next, a one-way air intake valve is installed at the bottom of the hollow box 21, and an exhaust pipe 24 is connected to the bottom of the hollow box 21. A first spiral groove 25 is provided on the inner wall of the exhaust pipe 24, and one end of the exhaust pipe 24 is located at the nozzle 10 and connected to a conical nozzle 26. A second spiral groove 27 is provided on the outer wall of the nozzle 10, and a one-way exhaust valve is installed at the exhaust pipe 24.

[0058] The working principle is as follows: the first wedge block 18 moves inside the hollow box 21 via the connecting rod 23, carrying the piston 22. The piston 22 moves and compresses the closed gas inside the hollow box 21. At this time, the one-way air inlet valve at the bottom of the hollow box 21 is closed, the gas pressure increases and opens the one-way exhaust valve on the exhaust pipe 24. The compressed gas enters the exhaust pipe 24, flows through the first spiral groove 25 on its inner wall and is given high-speed rotational motion. The high-speed swirling flow is converged and accelerated by the conical nozzle 26, forming a high-speed airflow that is precisely shot onto the surface of the nozzle 10.

[0059] Then, the second spiral groove 27 on the outside of the nozzle 10 will force the airflow to move in a spiral motion along the groove, forming a vortex around the nozzle 10. The vortex can cover more surfaces of the nozzle 10 (including sides and gaps that are difficult to reach by direct blowing), and the tangential force generated by the spiral motion can peel off the firmly attached dust, rather than just blowing away the floating dust by impact force, thus achieving full-circle cleaning.

[0060] When the first wedge block 18 drives the piston 22 to reset via the connecting rod 23, the internal volume of the hollow box 21 increases and the air pressure decreases to form a negative pressure. The one-way exhaust valve on the exhaust pipe 24 remains closed, while the one-way intake valve at the bottom of the hollow box 21 is opened under atmospheric pressure. External gas is drawn into the hollow box 21 through the valve to complete the gas storage process, thus reserving gas for subsequent purging actions.

[0061] In addition, the delay structure is linked to a spray expansion structure, which is used to expand the spray range of the nozzle 10.

[0062] Specifically, the spray expansion structure includes a first limiting groove 28 at the bottom of the spray pipe 3, and an iron plate 29 is slidably connected to the bottom of the spray pipe 3 along the first limiting groove 28. The iron plate 29 is fixed with a first rack 30 and a first arc-shaped baffle 31. A second limiting groove 32 is provided at the bottom of the spray pipe 3, and a second rack 33 is slidably connected to the bottom of the spray pipe 3 along the second limiting groove 32. A gear 34 is rotatably connected to the bottom of the spray pipe 3, and the gear 34 meshes with both the first rack 30 and the second rack 33. The second rack 33 is fixed with a second arc-shaped baffle 35.

[0063] The working principle described above is as follows: when the amount of fertilizer in tank 2 is low, the receiving plate 9 cannot be triggered to move. Therefore, the positions of the first arc-shaped baffle 31 and the second arc-shaped baffle 35 are very close together. Figure 12 As shown. When the nozzle 10 sprays the coating agent, the spraying area increases as it goes down (this is common knowledge). However, because the first arc-shaped baffle 31 and the second arc-shaped baffle 35 are very close together when spraying, the coating agent will be sprayed to the sides less. The purpose is to prevent the coating agent from spreading and being wasted when the amount of fertilizer is small.

[0064] Since the first wedge block 18 is made of magnet, when there is a lot of fertilizer, the first wedge block 18 will move along the first limiting groove 28 under the action of magnetic attraction, carrying the iron plate 29 and the first rack 30, and at the same time, it will carry the first arc-shaped baffle 31 along the exhaust pipe 24.

[0065] The first rack 30 moves via the gear 34, which in turn moves the second rack 33. The directions of movement of the first rack 30 and the second rack 33 are opposite; therefore, the width of the opening between the first rack 30 and the second rack 33 will change from... Figure 12 As the position shown increases, the area of ​​the coating agent sprayed by the nozzle 10 will increase significantly, thus adapting to scenarios with a large amount of fertilizer and achieving dynamic adjustment when the amount of fertilizer is large or small.

[0066] When the amount of fertilizer decreases, the baffle 11 resets under the action of the delay structure. The first wedge block 18 moves in the opposite direction with the iron plate 29 to achieve reset. Then the gear 34, the first rack 30, the second rack 33, and the second arc-shaped baffle 35 drive in the opposite direction, so that the first arc-shaped baffle 31 and the second arc-shaped baffle 35 come closer together again.

[0067] Additionally, it should be noted that the tank 2 of the present invention achieves the purpose of mixing / blending organic fertilizer and thus coating it, and removes dust and other impurities from the nozzle 10 through a dust removal structure, thereby realizing an integrated structural design of mixing / blending and impurity removal.

[0068] The working process of tank 2 is as follows:

[0069] Step 1: Put organic fertilizer into tank 2 and start rotating. The horizontal bar 37 lifts and throws the fertilizer. If the amount of fertilizer is small, the impact force when it falls to the receiving plate 9 is small. The baffle 11 keeps the nozzle 10 partially covered. At this time, the spray volume is low. The first arc-shaped baffle 31 and the second arc-shaped baffle 35 move closer to limit the spray range.

[0070] Step 2: After the amount of fertilizer in the tank 2 increases, the falling material impacts the receiving plate 9, generating an impact force and pushing the slider 7 downward. This pulls the rope 13, causing the baffle 11 to move and reduce the obstruction of the nozzle 10, thereby increasing the flow rate of the coating agent sprayed from the nozzle 10 and achieving adaptive adjustment of the spraying volume.

[0071] Step 3: When the baffle 11 moves, it drives the first wedge block 18 to move and misaligns with the second wedge block 20 to form a delay. At the same time, the connecting rod 23 pushes the piston 22 in the hollow box 21, compresses the gas and forms a swirling flow through the first spiral groove 25, and then the gas is gathered by the conical nozzle 26 and sprayed out onto the surface of the cleaning nozzle 10.

[0072] Step 4: When the first wedge block 18 made of magnet moves, it attracts the iron plate 29, and then drives the first rack 30 to drive the second rack 33 through the gear 34, so that the opening between the first arc-shaped baffle 31 and the second arc-shaped baffle 35 expands the spray range.

[0073] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
