Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilization equipment technology, specifically to a fertilizer spreading device with a guiding material dispensing structure. Background Technology

[0002] In agricultural production, fertilizer application is a crucial step in ensuring crop growth. Different types of fertilizers (such as granular fertilizer, powdered fertilizer, and block organic fertilizer) have significantly different physical properties, requiring a high degree of adaptability to the conveying structure. Traditional fertilizer application devices have a pusher rod at the bottom of the fertilizer storage bin, which pushes the fertilizer in the storage bin toward the application structure.

[0003] However, this conveying structure still has several problems in actual operation. For granular fertilizer with good flowability, the lack of restraint during the pushing process can easily lead to uneven fertilizer conveying. For powder fertilizer with poor flowability, the push rod can easily cause fertilizer to accumulate in "dead corners" at the bottom of the fertilizer storage bin, making it impossible to move smoothly to the discharge end.

[0004] Therefore, based on the above problems, it is necessary to make improvements. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a fertilizer spreading device with a guiding and feeding structure, which can effectively adjust the angle of different fertilizers such as granular fertilizer, powdered fertilizer, and block organic fertilizer to ensure the stability of fertilizer delivery.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fertilizer spreading device with a guiding and distributing structure includes a fertilizer storage bin, a fertilizer spreading component disposed at the discharge end of the fertilizer storage bin, and a distributing structure disposed at the bottom of the fertilizer storage bin for pushing fertilizer to the discharge end. The distributing structure includes a distributing chain and distributing push rods. The distributing chains are symmetrically arranged on both sides of the bottom of the fertilizer storage bin, and several distributing push rods are arranged between the distributing chains on both sides. The distributing push rods push the fertilizer in the fertilizer storage bin toward the fertilizer spreading component, and the fertilizer spreading component spreads the fertilizer outward. The distributing push rods are provided with a guiding component, which includes a guide plate and an angle adjusting component. The guide plate is movably connected to the distributing push rods through the angle adjusting component, and the angle adjusting component is used to adjust and fix the angle of the guide plate.

[0008] Preferably, one end of the guide plate is movably connected to the feeding push rod via a rotating shaft, and the other end of the guide plate away from the feeding push rod is inclined in the opposite direction to the discharge end. The angle adjustment component is at least provided on one side of the guide plate. The angle adjustment component includes an adjustment plate vertically arranged on the feeding push rod, an arc-shaped adjustment hole opened on the adjustment plate, and a bolt that moves within the arc-shaped adjustment hole on one side of the guide plate. One end of the bolt passes through the arc-shaped adjustment hole and is connected to the guide plate, and the other end is locked and fixed to the adjustment plate by an adjustment nut, thereby realizing the angle of the guide plate being fixed and adjusted.

[0009] Preferably, the guide plate extends along the length of the material push rod, and the angle adjustment component is provided on both sides and in the middle of the guide plate. The angle adjustment component in the middle of the guide plate is provided with a clearance hole that matches the shape of the adjustment plate.

[0010] Preferably, the material feeding push rod extends towards the bottom of the fertilizer storage bin and is further provided with a scraper. One end of the scraper is connected to the material feeding push rod, and the other end is tightly fitted to the bottom of the fertilizer storage bin. The scraper extends along the length of the material feeding push rod.

[0011] Preferably, a transmission mechanism is also provided, which includes an engine, a first transmission component, and a second transmission component; the output end of the engine is driven to the first transmission component via a chain, the first transmission component is driven to the second transmission component via a chain, the first transmission component is used to drive the fertilizer spreading component, and the second transmission component is used to drive the material feeding structure.

[0012] Preferably, the first transmission assembly includes a first transmission wheel and a first transmission shaft. The first transmission wheel and the first transmission shaft are coaxially and fixedly connected. The output end of the engine is driven to rotate by the first transmission wheel via a belt, and the first transmission wheel connected to the first transmission wheel rotates. The first transmission shaft is provided with a bevel gear assembly and is driven to rotate by the fertilizer spreading assembly.

[0013] Preferably, the fertilizer spreading assembly includes a rotating roller and a fertilizer spreading disc disposed at the end of the rotating roller. The fertilizer spreading disc is provided with a plurality of guide vanes, and the rotating roller has spiral blades for dispersing fertilizer. The bevel gear assembly includes a driving bevel gear coaxially fixedly connected to a first transmission shaft, and the rotating roller is provided with a driven bevel gear that meshes with the driving bevel gear. The first transmission shaft drives the rotating roller to rotate by driving the driving bevel gear and the driven bevel gear to cooperate with each other, thereby driving the fertilizer spreading disc to rotate and spread fertilizer outward.

[0014] Preferably, the second transmission assembly includes a second transmission wheel and a ratchet mechanism. A transmission gear is coaxially fixedly connected to one side of the first transmission wheel. The transmission gear is driven to rotate the second transmission wheel by a chain. The second transmission wheel drives the ratchet mechanism to rotate by a transmission arm.

[0015] Preferably, the ratchet mechanism includes a ratchet, a double-bearing eccentric wheel offset from the axis on the second transmission wheel, a drive pawl that cooperates with the ratchet on the transmission arm, and an elastic element connecting the drive pawl and the transmission arm to keep the drive pawl in contact with the ratchet; when the second transmission wheel rotates, its double-bearing eccentric wheel pushes the transmission arm to swing, and when the transmission arm swings, it drives the ratchet to rotate intermittently in one direction through the drive pawl; a second transmission shaft is coaxially fixedly connected to the ratchet, and a drive gear on the second transmission shaft drives the feeding chain to work.

[0016] Preferably, a limiting pawl is provided above the ratchet, and a return spring is provided between the limiting pawl and the transmission arm. One end of the return spring is connected to the limiting pawl, and the other end is connected to the transmission arm. After the driving force of the double bearing eccentric wheel on the transmission arm disappears, the return spring resets the transmission arm to achieve reciprocating swing.

[0017] Compared with existing technologies, the beneficial effects of this utility model are as follows: By incorporating a guide plate and angle adjustment components, the tilt angle of the guide plate can be flexibly adjusted, allowing for precise adaptation to fertilizers with different physical properties, such as granular fertilizers, powdered fertilizers, and block organic fertilizers, without the need to replace any conveying components. The guide assembly can form a suitable conveying constraint through angle optimization, significantly improving the device's adaptability to various types of fertilizers, reducing the difficulty of adjustment during fertilizer change operations, and enhancing the equipment's versatility. Furthermore, the inclusion of a scraper plate, which moves synchronously with the push rod, effectively scrapes away fertilizer adhering to or accumulating at the bottom of the silo in real time. This completely solves the problem of fertilizer easily forming "dead corners" at the bottom of the silo and the difficulty in cleaning up block organic fertilizer debris, ensuring smooth conveying of fertilizer from the bottom of the silo to the discharge end. This avoids conveying interruptions or fertilizer waste caused by accumulation, indirectly improving the continuity and efficiency of the overall fertilizer spreading operation.

[0027] Please see Figures 1 to 6 The fertilizer spreading device shown includes a fertilizer storage bin 1, a fertilizer spreading component 2, a material spreading structure 3, and a transmission mechanism.

[0028] The fertilizer spreading component 2 is located at the discharge end of the fertilizer storage bin 1, and the material spreading structure 3 is located at the bottom of the fertilizer storage bin 1 to push fertilizer towards the discharge end. The material spreading structure 3 includes a material spreading chain 4 and a material spreading push rod 5. The material spreading chain 4 is symmetrically arranged on both sides of the bottom of the fertilizer storage bin 1, and several material spreading push rods 5 are provided between the material spreading chains 4 on both sides. The material spreading push rods 5 push the fertilizer in the fertilizer storage bin 1 towards the fertilizer spreading component 2, and the fertilizer spreading component 2 spreads the fertilizer outward. The material spreading push rod 5 is provided with a guide component, which includes a guide plate 6 and an angle adjustment component 7. The guide plate 6 is movably connected to the material spreading push rod 5 through the angle adjustment component 7, and the angle adjustment component 7 is used to adjust and fix the angle of the guide plate 6. One end of the guide plate 6 is movably connected to the feeding push rod 5 via a rotating shaft 8. The other end of the guide plate 6, away from the feeding push rod 5, is inclined in the opposite direction to the discharge end. The angle adjustment component 7 is provided on at least one side of the guide plate 6. The angle adjustment component 7 includes an adjustment plate 9 vertically arranged on the feeding push rod 5, an arc-shaped adjustment hole 10 opened on the adjustment plate 9, and a bolt that moves within the arc-shaped adjustment hole 10 on one side of the guide plate 6. One end of the bolt passes through the arc-shaped adjustment hole 10 and is connected to the guide plate 6, and the other end is locked and fixed on the adjustment plate 9 by an adjustment nut 11, thereby realizing the angle of the guide plate 6 being fixed and adjusted. The guide assembly, through the adjustment of the arc-shaped adjustment hole 10 on the upright plate 9 and its engagement with bolts, can achieve continuous angle adjustment within the range of 30°-60°. This allows for precise matching of conveying requirements to fertilizers with different physical properties. For example, for granular fertilizers with good flowability (such as urea granules), adjusting the angle to 35°-40° reduces the angle between the guide plate 6 and the push rod 5, thus constraining and pushing the granular fertilizer. For powdered fertilizers with poor flowability (such as potassium dihydrogen phosphate powder), adjusting the angle to 55°-60° expands the pushing cross-section and angle, reducing the contact and adhesion between the powder and the guide plate 6, thereby reducing the conveying blockage rate. This allows for adaptation to granular and powdered fertilizers without replacing conveying components, covering scenarios such as grain crops, cash crops, and fruit and vegetable cultivation.

[0029] Preferably, the guide plate 6 extends along the length of the feeding push rod 5, and the angle adjustment component 7 is provided on both sides and in the middle of the guide plate 6. The angle adjustment component 7 in the middle of the guide plate 6 is provided with a clearance hole 12 that matches the shape of the adjustment plate 9.

[0030] Angle adjustment process for guide components:

[0031] (1) Loosen the adjusting nut 11: When it is necessary to adapt to different fertilizers, loosen the adjusting nuts 11 on both sides and in the middle of the guide plate 6 so that the bolts can slide freely in the arc-shaped adjusting hole 10;

[0032] (2) Adjust the guide angle: Adjust the tilt angle of the guide plate 6 according to the characteristics of the fertilizer. For granular fertilizer with good flowability, adjust the guide plate 6 slightly inward (decrease the tilt angle by 5-10°) to enhance the constraint on the fertilizer and prevent it from scattering and failing to push effectively. For powder fertilizer or block organic fertilizer with poor flowability, adjust the guide plate 6 slightly outward (increase the tilt angle by 10-15°) to increase the pushing contact section and angle and reduce fertilizer retention.

[0033] (3) Locking and fixing: After the angle is adjusted to the correct position, tighten the adjusting nut 11 to press the bolt against the adjusting plate 9 and fix the angle of the guide plate 6 to ensure that the guide plate 6 does not move during the material feeding process.

[0034] like Figure 3 As shown, the feeding push rod 5 is further extended towards the bottom of the fertilizer storage bin 1 by a scraper plate 13. One end of the scraper plate 13 is connected to the feeding push rod 5, and the other end is tightly fitted to the bottom of the fertilizer storage bin 1. The scraper plate 13 extends along the length of the feeding push rod 5. The scraper plate 13 at the bottom of the feeding push rod 5 is made of wear-resistant rubber, fits snugly against the bottom of the fertilizer storage bin 1, and extends along the full length of the feeding push rod 5, thereby covering the entire width of the bin bottom. As it moves synchronously with the feeding push rod 5, it can scrape off the fertilizer adhering to the bin bottom in real time. Addressing the issue of fertilizer accumulating at the bottom of the bin, which is common in traditional devices, the scraper plate 13 can scrape off the accumulated fertilizer, thoroughly cleaning the "dead corners" of the bin bottom. For small fragments of lumpy organic fertilizer residue, the scraper plate 13 can also scrape them off, preventing long-term accumulation and deterioration, effectively reducing fertilizer waste and secondary cleaning costs.

[0035] like Figure 4 and Figure 6 As shown, the transmission mechanism consists of an engine 14, a first transmission assembly, and a second transmission assembly, which provides power to the fertilizer spreading assembly 2 and the material dispensing structure 3 and enables them to operate in tandem. The output end of the engine 14 is driven to the first transmission assembly via a belt. The first transmission assembly includes a first transmission wheel 15 and a first transmission shaft 16. The first transmission wheel 15 and the first transmission shaft 16 are coaxially and fixedly connected. When the engine 14 is running, it drives the first transmission wheel 15 to rotate via the belt, thereby driving the first transmission shaft 16 to rotate synchronously.

[0036] A drive bevel gear 21 is coaxially fixedly connected to the first drive shaft 16, and a driven bevel gear 22 that meshes with the drive bevel gear 21 is provided on the rotating roller 17. The first drive shaft 16 transmits power to the rotating roller 17 through the meshing of the drive bevel gear 21 and the driven bevel gear 22, thereby driving the rotating roller 17 to rotate stably.

[0037] A transmission gear 24 is coaxially fixedly connected to one side of the first transmission wheel 15. The transmission gear 24 is driven by a chain to the second transmission assembly. The second transmission assembly includes a second transmission wheel 23 and a ratchet mechanism. The first transmission wheel 15 is coaxially fixedly connected to one side of the transmission gear 24, and the transmission gear 24 is driven by a chain to the second transmission wheel 23, causing the second transmission wheel 23 to rotate. The ratchet mechanism includes a transmission arm 25, a ratchet 26, and a return spring 32. The second transmission wheel 23 is provided with a double-bearing eccentric wheel 27 off-center from the axis. The transmission arm 25 is provided with a driving pawl 28 that cooperates with the ratchet 26. The driving pawl 28 is connected to the transmission arm 25. An elastic element, a spring, is provided to keep the drive pawl 28 in contact with the ratchet 26. One end of the spring is connected to the pawl, and the other end is connected to the transmission arm 25. A limiting pawl 31 is provided above the ratchet 26. One end of the return spring 32 is connected to the limiting pawl 31, and the other end is connected to the transmission arm 25. When the second transmission wheel 23 rotates, its double-bearing eccentric wheel 27 will periodically push the transmission arm 25 to swing. When the transmission arm 25 swings, it drives the ratchet 26 to rotate intermittently in one direction through the pawl. When the pushing effect of the double-bearing eccentric wheel 27 on the transmission arm 25 disappears, the return spring 32 will pull the transmission arm 25 to return to its original position, realizing the reciprocating swing of the transmission arm 25.

[0038] When the drive arm 25 swings, the drive pawl 28 pushes the ratchet 26 to rotate. The limit pawl 31 is pulled by the return spring 32 to keep it in contact with the ratchet 26 and embedded in the tooth groove of the ratchet 26 to prevent reverse rotation. After the double bearing eccentric wheel 27 rotates past the top, the return spring 32 pulls the drive arm 25 to reset, and the drive pawl 28 slides along the tooth surface of the ratchet 26 to the next tooth groove under the action of the torsion spring. During this process, the second drive shaft 29 rotates intermittently with the ratchet 26, driving the drive gear 30 to drive the feeding chain 4, so that the feeding push rod 5 pushes fertilizer intermittently. For example, each push corresponds to the rotation of the rotating roller 17 rotating 2 revolutions, ensuring that the feeding and spreading rhythm are matched.

[0039] The ratchet 26 is coaxially fixedly connected to the second drive shaft 29, and the second drive shaft 29 is provided with a drive gear 30. The drive gear 30 is driven to connect with the feeding chain 4. The power transmitted by the ratchet 26 mechanism drives the feeding chain 4 to rotate, thereby realizing the operation of the feeding structure 3.

[0040] like Figure 5As shown, the fertilizer spreading assembly 2 includes a rotating roller 17 and a fertilizer spreading disc 18 disposed at the end of the rotating roller 17. The fertilizer spreading disc 18 is provided with a plurality of guide vanes 19. The rotating roller 17 has spiral blades 20 for dispersing fertilizer. The bevel gear assembly includes a driving bevel gear 21 coaxially fixedly connected to a first transmission shaft 16. The rotating roller 17 is provided with a driven bevel gear 22 that meshes with the driving bevel gear 21. The first transmission shaft 16 drives the rotating roller 17 to rotate by driving the driving bevel gear 21 and the driven bevel gear 22 to cooperate with each other, thereby driving the fertilizer spreading disc 18 to rotate and spread fertilizer outward.

[0041] like Figure 2 As shown, the feeding structure 3 is located at the bottom of the fertilizer storage bin 1 and is used to push the fertilizer towards the discharge end. It includes a feeding chain 4 and feeding push rods 5. The feeding chains 4 are symmetrically arranged on both sides of the bottom of the fertilizer storage bin 1. Several feeding push rods 5 are horizontally connected between the feeding chains 4 on both sides. The feeding push rods 5 rotate with the feeding chains 4 and can push the fertilizer in the fertilizer storage bin 1 towards the fertilizer spreading component 2 evenly and continuously, ensuring a stable fertilizer supply.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
