Description

Technical Field

[0001] This invention relates to the field of agricultural fertilization equipment technology, and in particular to an agricultural fertilization device with high fertilization efficiency. Background Technology

[0002] Fertilizer is a core production material for ensuring stable and increased crop yields and improving the overall efficiency of agricultural production. Scientific, precise, efficient, and low-consumption fertilization is a key link in achieving a stable and secure food supply and promoting high-quality development of modern agriculture. Fertilizers are mostly soluble salt compounds with strong hygroscopic properties. During storage, transportation, and field storage, they are prone to clumping due to factors such as dampness and pressure from stacking. Clumped fertilizer cannot be directly applied to conventional fertilization operations. Therefore, before applying fertilizer, it is necessary to pre-treat the clumped fertilizer using agricultural fertilization equipment to ensure the smooth and stable implementation of subsequent fertilization operations.

[0003] Existing agricultural fertilization devices are mostly equipped with fertilizer crushing structures. Although they can crush clumps of fertilizer, in pursuit of crushing efficiency, they generally adopt high-intensity hard impact, crushing, and shearing crushing methods. The rigid force of the mechanical structure directly crushes the clumps of fertilizer. During the high-intensity hard crushing process, the rigid impact and high-speed friction between the mechanical structure and the fertilizer particles will generate local instantaneous high temperatures. For fertilizers with poor thermal stability, such as urea and ammonium nitrogen fertilizer, it is very easy to cause the volatilization and decomposition of effective nitrogen, which directly leads to the loss of fertilizer nutrients and a decrease in fertilizer efficiency. Therefore, a high-efficiency agricultural fertilization device is proposed. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides an agricultural fertilization device with high fertilization efficiency.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A high-efficiency agricultural fertilization device includes a storage bin, an iron plow for turning over the soil is installed below the storage bin, a fertilizer pipe for conveying fertilizer is installed between the storage bin and the iron plow, a bagged fertilizer storage mechanism for storing whole bags of fertilizer is installed above the storage bin, and a fertilizer crushing mechanism for crushing fertilizer is installed above the bagged fertilizer storage mechanism.

[0007] The bagged fertilizer storage mechanism can form a circumferential limiting constraint and overall positioning fixation for the whole bag of fertilizer, restricting the displacement of the bagged fertilizer during the crushing process, so that the fertilizer crushing mechanism can crush and break up the clumps of fertilizer inside the bag.

[0008] The fertilizer crushing mechanism can crush the clumps of fertilizer inside the whole bag of fertilizer that is fixed in place by the bagged fertilizer storage mechanism, and crush and disperse the whole bag of clumps of fertilizer through the crushing action.

[0009] The fertilizer crushing mechanism includes a crossbeam positioned above the storage bin. A bidirectional synchronous electric push rod is fixed in the middle of the crossbeam. Both ends of the bidirectional synchronous electric push rod are hinged with a main hinge plate and a secondary hinge plate. A crushing roller for crushing the fertilizer is provided at the end of the main hinge plate and the secondary hinge plate away from the bidirectional synchronous electric push rod. A pressure plate for pressing the fertilizer is also provided between the two crushing rollers. Two side pressure plates for squeezing the middle of the fertilizer are also provided below the bidirectional synchronous electric push rod.

[0010] As a preferred embodiment of the present invention, two connecting rods are fixed at both ends of the bidirectional synchronous electric push rod, and two main drive rods are provided below the two connecting rods;

[0011] The ends of the two main hinge plates and the two auxiliary hinge plates away from the rolling roller are all sleeved on the outside of the main drive rod, and the ends of the main hinge plates and auxiliary hinge plates away from the main drive rod are movably connected to the auxiliary drive rod.

[0012] The two main hinge plates and the two auxiliary hinge plates are joined together by the two main drive rods and the two auxiliary drive rods to form a rhomboid adjustable structure. Each of the two main hinge plates has a through groove in its center. The two auxiliary hinge plates are inserted into the through grooves one-to-one. The insertion and engagement of the auxiliary hinge plates with the through grooves achieves the limiting and guiding of the rhomboid structure's shape. The two telescopic rods of the bidirectional synchronous electric push rod retract simultaneously. The telescopic rods of the bidirectional synchronous electric push rod drive the connecting rod to move closer to the pressure plate. The two connecting rods drive the two main drive rods to move to opposite sides, reducing the distance between the two main drive rods. The two main drive rods, through the two main hinge plates and the two auxiliary hinge plates, drive the auxiliary drive rods to move away from the pressure plate, increasing the distance between the two auxiliary drive rods. The two auxiliary drive rods drive the two crushing rollers to move in opposite directions. The two crushing rollers perform a crushing operation on the bagged fertilizer, fully crushing the clumps inside the bagged fertilizer and breaking down the clumps.

[0013] As a preferred embodiment of the present invention, a limiting collar is fixed at the bottom of the auxiliary transmission rod, and an annular groove adapted to the limiting collar is provided in the middle of the rolling roller.

[0014] An extension rod is also fixed at the bottom of the main drive rod, and a through hole adapted to the extension rod is opened at one end of the side pressure plate near the main drive rod.

[0015] A limiting collar is fitted inside the annular groove. The extension rod is rectangular, and the side pressure plate is V-shaped. A baffle is fixed to the bottom of the extension rod. The baffle at the bottom of the extension rod limits the side pressure plate and prevents it from falling off the extension rod. The rectangular extension rod cooperates with the side pressure plate to prevent the side pressure plate from rotating when it comes into contact with the bagged fertilizer. When the bidirectional synchronous electric push rod drives the main drive rod to move to the opposite side through the connecting rod, the two main drive rods drive the two extension rods to move to the opposite side. The two extension rods drive the two side pressure plates to move to the opposite side, reducing the distance between the two side pressure plates. The two side pressure plates then compress the sides of the bagged fertilizer.

[0016] As a preferred embodiment of the present invention, a threaded sleeve is fixed at the bottom of the crossbeam, and a central shaft is movably connected below the threaded sleeve.

[0017] The outer wall of the central shaft is also fixed with a gear, and the outer wall of the main drive rod is also provided with an extension rod. The end of the extension rod away from the main drive rod is also fixed with a rack that meshes with the gear.

[0018] The extension rod is sleeved on the upper half of the outer wall of the main drive rod. The upper half of the central shaft is provided with a threaded part. The middle of the threaded sleeve is provided with a threaded hole that matches the threaded part. The gear is located below the threaded part. When the two main drive rods move towards the side closer to the central shaft, the two main drive rods drive the two racks to move towards the opposite side through the two extension rods. The two racks mesh with the gear, causing the gear to drive the central shaft to rotate. The central shaft drives the threaded part to rotate, so that the threaded part cooperates with the threaded hole to drive the central shaft to move vertically up and down. The central shaft drives the pressure plate to move vertically downward, and the pressure plate presses the middle of the bagged fertilizer.

[0019] As a preferred embodiment of the present invention, the outer wall of the threaded sleeve is further fixed with two lugs, the top of the pressure plate is further fixed with two limiting rods, and the middle of the two lugs is further provided with mounting holes that are compatible with the limiting rods.

[0020] The top of the hanging ear is also fixed with a chuck, the diameter of which is larger than the diameter of the mounting hole;

[0021] When the central shaft rotates, the pressure plate is stopped and limited by the cooperation of the limiting rod and the hanging lug, preventing the pressure plate from rotating synchronously during the rotation of the central shaft, ensuring the stable output of the rotation of the central shaft, and avoiding the pressure plate from moving around and affecting the accuracy and stability of the device's compaction and dispersing operation.

[0022] As a preferred embodiment of the present invention, a tray is fixed to the bottom of the central shaft, and a limiting hole adapted to the tray is provided at the bottom of the pressure plate. An insertion hole adapted to the central shaft is also provided in the middle of the pressure plate. The limiting hole and the insertion hole are connected. The tray forms a travel limit and buffer constraint on the pressure plate, limiting the maximum travel of the pressure plate downward and preventing the pressure plate from directly contacting the bagged fertilizer due to excessive impact force when it moves downward.

[0023] As a preferred embodiment of the present invention, the bagged fertilizer storage mechanism includes two support plates disposed above the storage box, two springs fixed to the bottom of each support plate for supporting them, two support plates fixed above the two support plates, and two barriers fixed to the top of the two support plates for limiting the position of the bagged fertilizer.

[0024] As a preferred embodiment of the present invention, two load-bearing plates are further provided on the opposite side of the two support plates, and two insert rods are further provided between the two load-bearing plates and the two support plates. A chamfer is also provided on the opposite side of the two load-bearing plates.

[0025] The two support plates are recessed inward to form a sliding groove that matches the load-bearing plate. The end of the insertion rod away from the load-bearing plate is also fixed with an insertion block. The support plate has a slot inside to facilitate the movement of the insertion rod. A spring is also fixed inside the slot.

[0026] When the two main drive rods move towards the side closer to the central shaft, they drive the two extension rods to move synchronously towards each other. The two extension rods then drive the two side pressure plates to move towards each other. The two side pressure plates come into contact with the chamfers of the two load-bearing plates, causing them to push the two load-bearing plates into the grooves of the support plate. The load-bearing plates push the insert rod into the slot. The insert rod compresses the spring through the insert block. The two load-bearing plates support the middle of the bagged fertilizer.

[0027] As a preferred embodiment of the present invention, two electric slide rails are fixed to the side of the support plate that is away from each other. Two electric hydraulic rods are also fixed to the top of the two electric slide rails. The piston rods of the two electric hydraulic rods are fixed to the bottom of the crossbeam. A knife holder is also fixed to the bottom of the two electric slide rails. A bag-breaking knife for opening the bagged fertilizer is also fixed to the top of the knife holder. When the electric slide rails move laterally, the electric slide rails drive the knife holder to move laterally, and the knife holder drives the bag-breaking knife to move laterally. The blade of the bag-breaking knife contacts the bottom of the bagged fertilizer. The bag-breaking knife continuously cuts the packaging bag of the fertilizer through its lateral movement, allowing the fertilizer inside the bag to fall smoothly into the storage box.

[0028] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0029] This invention utilizes a combination of structures including a fertilizer storage mechanism, a fertilizer fragmentation mechanism, a bidirectional synchronous electric push rod, a connecting rod, a rolling roller, a main hinge plate, a secondary hinge plate, a main transmission rod, a limiting collar, and a secondary transmission rod. It employs a flexible rolling and crushing method to break up clumps, avoiding the instantaneous high temperatures caused by rigid friction that lead to nitrogen volatilization and decomposition, thus ensuring the integrity of the fertilizer's effectiveness. Simultaneously, it significantly reduces the generation of ultrafine powder, eliminating powder dust waste and secondary moisture absorption, clumping, and material blockage, aligning with the development trend of reducing fertilizer usage and increasing efficiency.

[0030] This invention utilizes a combination of structures including a bidirectional synchronous electric push rod, a connecting rod, a side pressure plate, a main hinge plate, a secondary hinge plate, a main transmission rod, a limiting collar, and a secondary transmission rod. The synchronous compression of the side pressure plate causes clumps of fertilizer inside the bag to gather towards the center, reducing the gaps between clumps and allowing the crushing force to be fully transmitted to all clumps inside the bag. This solves the problem of ineffective crushing of clumps at the edge of the bag, achieving uniform crushing of the entire bag without dead angles, completely eliminating residual hard lumps, and preventing subsequent fertilizer discharge blockage from the source.

[0031] This invention utilizes a combination of bidirectional synchronous electric push rods, connecting rods, pressure plates, extension rods, racks, gears, central shafts, threaded sleeves, limiting rods, and hanging ears. While the side pressure plate squeezes the middle of the bag's side, it simultaneously applies vertical pressure to the top of the bag. This multi-directional synchronous limiting system on the sides and top ensures that the fertilizer inside the bag remains in a dense, compact state. This allows the crushing force of the crushing rollers to be fully and evenly distributed throughout the bag, eliminating blind spots and significantly improving the uniformity and thoroughness of the crushing process.

[0032] This invention utilizes the coordination of structures such as an electro-hydraulic rod, connecting rod, main hinge plate, secondary hinge plate, main transmission rod, limiting collar, and secondary transmission rod. The main hinge plate, secondary hinge plate, main transmission rod, and secondary transmission rod are spliced ​​together to form a rhomboid adjustable structure. By utilizing the mechanical properties of rhomboid deformation, and using the electro-hydraulic rod as a unified drive source, power is precisely transmitted through the connecting rod to achieve alternating linkage between the side pressure plate clamping and limiting and the reciprocating rolling of the crushing roller. The action is seamless, completely solving the problem of the lengthy step-by-step operation process in the existing technology, and significantly improving the efficiency of agglomeration crushing.

[0033] This invention utilizes a combination of structures such as a support plate, enclosure, support plate, load-bearing plate, spring, insert rod, insert block, and side pressure plate. While the side pressure plate is squeezing the bag, the load-bearing plate is simultaneously pushed back, actively releasing the deformation space at the bottom of the bag. This effectively alleviates the problem of sudden increase in internal pressure caused by side squeezing, prevents the packaging bag from bursting or breaking due to excessive internal pressure, eliminates operational malfunctions such as fertilizer spillage, and ensures the safety and stability of bagged crushing operations.

[0034] This invention utilizes a combination of structures such as an electric slide rail, an electric hydraulic rod, a crossbeam, a bag-breaking knife, and a knife holder. By moving the bag-breaking knife laterally, it continuously cuts the packaging bags of bagged fertilizer, allowing the fertilizer inside the bags to fall smoothly into the storage bin. This achieves automatic bag opening and unloading of fertilizer bags, eliminating the need for manual bag opening and improving the operating efficiency of the device. Attached Figure Description

[0048] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0049] Example: The present invention provides, as follows Figure 1 and Figure 2 The agricultural fertilization device shown includes a storage bin 1, an iron plow 2 for turning over the soil is installed below the storage bin 1, and a fertilizer pipe 3 for conveying fertilizer is installed between the storage bin 1 and the iron plow 2.

[0050] As can be seen from the above, when fertilization is required, the storage box 1 is connected to the tractor, the fertilizer is put into the storage box 1, the tractor drives the storage box 1 to move, the storage box 1 drives the iron plow 2 to till the land that needs to be fertilized, and the fertilizer inside the storage box 1 is transported into the tilled soil through the fertilizer pipe 3.

[0051] refer to Figure 2 , Figure 3 and Figure 4 As shown, a fertilizer crushing mechanism 5 for crushing fertilizer is provided above the bagged fertilizer storage mechanism 4.

[0052] The fertilizer crushing mechanism 5 can crush the clumps of fertilizer inside the whole bag of fertilizer that is fixed and limited by the bagged fertilizer storage mechanism 4, and crush and disperse the whole bag of clumps of fertilizer through the crushing action.

[0053] The fertilizer crushing mechanism 5 includes a crossbeam 503 positioned above the storage bin 1. A bidirectional synchronous electric push rod 504 is fixed in the middle of the crossbeam 503. Both ends of the bidirectional synchronous electric push rod 504 are hinged with a main hinge plate 509 and a secondary hinge plate 510. A crushing roller 507 for crushing the fertilizer is provided at the end of the main hinge plate 509 and the secondary hinge plate 510 away from the bidirectional synchronous electric push rod 504. A pressure plate 508 for pressing the fertilizer is also provided between the two crushing rollers 507. Two side pressure plates 506 for squeezing the middle of the fertilizer are also provided below the bidirectional synchronous electric push rod 504.

[0054] refer to Figure 3 , Figure 4 and Figure 5 As shown, two connecting rods 505 are fixed at both ends of the bidirectional synchronous electric push rod 504, and two main drive rods 511 are provided below the two connecting rods 505.

[0055] The ends of the two main hinge plates 509 and the two auxiliary hinge plates 510 away from the rolling roller 507 are all sleeved on the outside of the main drive rod 511, and the ends of the main hinge plates 509 and the auxiliary hinge plates 510 away from the main drive rod 511 are movably connected to the auxiliary drive rod 513.

[0056] Two main hinge plates 509 and two auxiliary hinge plates 510 are joined together by two main drive rods 511 and two auxiliary drive rods 513 to form a rhomboid adjustable structure. Each of the two main hinge plates 509 has a through slot in its center. The two auxiliary hinge plates 510 are inserted into the through slots one-to-one. The insertion and engagement of the auxiliary hinge plates 510 with the through slots achieves the limiting and guiding adjustment of the rhomboid structure. The two telescopic rods of the bidirectional synchronous electric push rod 504 retract simultaneously. The telescopic rods of the bidirectional synchronous electric push rod 504 drive the connecting rod 505 to move towards the side closer to the pressure plate 508. The connecting rod 505 drives the two main drive rods 511 to move to opposite sides, reducing the distance between them. The two main drive rods 511 then drive the auxiliary drive rods 513 to move away from the pressure plate 508 via the two main hinge plates 509 and the two auxiliary hinge plates 510, increasing the distance between them. The two auxiliary drive rods 513 then drive the two crushing rollers 507 to move in opposite directions, crushing the bagged fertilizer and breaking down the clumps.

[0057] refer to Figure 4 , Figure 5 and Figure 6 As shown, a limiting collar 512 is also fixed at the bottom of the auxiliary transmission rod 513, and an annular groove that matches the limiting collar 512 is also provided in the middle of the rolling roller 507.

[0058] An extension rod 514 is also fixed at the bottom of the main drive rod 511, and a through hole adapted to the extension rod 514 is opened at one end of the side pressure plate 506 near the main drive rod 511.

[0059] The limiting collar 512 is fitted into the annular groove. The extension rod 514 is rectangular, and the side pressure plate 506 is V-shaped. A baffle is fixed to the bottom of the extension rod 514. The baffle at the bottom of the extension rod 514 limits the side pressure plate 506 to prevent it from falling off the extension rod 514. The rectangular extension rod 514 cooperates with the side pressure plate 506 to prevent the side pressure plate 506 from rotating when it comes into contact with the bagged fertilizer. When the bidirectional synchronous electric push rod 504 drives the main drive rod 511 to move to the opposite side through the connecting rod 505, the two main drive rods 511 drive the two extension rods 514 to move to the opposite side, and the two extension rods 514 drive the two side pressure plates 506 to move to the opposite side, making the distance between the two side pressure plates 506 smaller. The two side pressure plates 506 squeeze the sides of the bagged fertilizer.

[0060] refer to Figure 7 As shown, the outer wall of the threaded sleeve 519 is also fixed with two lugs 521, and the top of the pressure plate 508 is also fixed with two limit rods 520. The middle of the two lugs 521 is also provided with mounting holes that are compatible with the limit rods 520.

[0061] The top of the 521 hook is also fixed with a chuck, the diameter of which is larger than the diameter of the mounting hole;

[0062] When the central shaft 518 rotates, the limiting rod 520 and the lug 521 cooperate to prevent the pressure plate 508 from rotating synchronously during the rotation of the central shaft 518, thus ensuring the stable output of the rotation of the central shaft 518 and preventing the pressure plate 508 from moving around and affecting the accuracy and stability of the device's compaction and dispersing operation.

[0063] refer to Figure 7 As shown, a tray 522 is fixed to the bottom of the central shaft 518. The bottom of the pressure plate 508 is provided with a limiting hole that matches the tray 522, and the middle of the pressure plate 508 is also provided with an insertion hole that matches the central shaft 518. The limiting hole and the insertion hole are connected. The tray 522 forms a stroke limit and buffer constraint on the pressure plate 508, limiting the limit stroke of the pressure plate 508 moving downward, and preventing the pressure plate 508 from directly making rigid contact with the bagged fertilizer due to excessive impact force when moving downward.

[0064] refer to Figure 8 , Figure 9 and Figure 10As shown, a bagged fertilizer storage mechanism 4 is provided above the storage bin 1 to store whole bags of fertilizer. The bagged fertilizer storage mechanism 4 can form circumferential limiting constraints and overall positioning fixation for the whole bag of fertilizer, restricting the displacement of the bagged fertilizer during the crushing process, so that the fertilizer crushing mechanism 5 can crush and break up the clumps of fertilizer in the bag. The bagged fertilizer storage mechanism 4 includes two support plates 401 set above the storage bin 1. Two springs 405 are fixed to the bottom of the two support plates 401 to support them. Two support plates 403 are also fixed above the two support plates 401. Two barriers 402 that limit the movement of the bagged fertilizer are also fixed to the top of the two support plates 403.

[0066] The two support plates 403 are recessed inward to form a sliding groove that matches the load-bearing plate 404. The end of the insertion rod 406 away from the load-bearing plate 404 is also fixed with an insertion block 407. The support plate 403 has a slot inside to facilitate the movement of the insertion rod 406. A spring 405 is also fixed inside the slot.

[0067] When the two main drive rods 511 move towards the side closer to the central shaft 518, the two main drive rods 511 drive the two extension rods 514 to move synchronously towards each other. The two extension rods 514 drive the two side pressure plates 506 to move towards each other. The two side pressure plates 506 contact the chamfers of the two load-bearing plates 404, causing the two side pressure plates 506 to push the two load-bearing plates 404 into the groove of the support plate 403. The load-bearing plates 404 push the insertion rod 406 into the slot. The insertion rod 406 compresses the spring 405 through the insertion block 407. The two load-bearing plates 404 can support the middle of the bagged fertilizer.

[0068] refer to Figure 8 , Figure 9 and Figure 10As shown, two electric slide rails 501 are fixed on the side of the support plate 401 that is far away from each other. Two electric hydraulic rods 502 are also fixed on the top of the two electric slide rails 501. The piston rods of the two electric hydraulic rods 502 are fixed to the bottom of the crossbeam 503. A knife holder 524 is also fixed on the bottom of the two electric slide rails 501. A bag-breaking knife 523 for opening the bagged fertilizer is also fixed on the top of the knife holder 524. When the electric slide rails 501 move laterally, the electric slide rails 501 drive the knife holder 524 to move laterally. The knife holder 524 drives the bag-breaking knife 523 to move laterally. The blade of the bag-breaking knife 523 contacts the bottom of the bagged fertilizer. The bag-breaking knife 523 continuously cuts the packaging bag of the fertilizer through its lateral movement, so that the fertilizer inside the bag falls smoothly into the storage box 1.

[0069] The two telescopic rods of the bidirectional synchronous electric push rod 504 retract simultaneously. The telescopic rods of the bidirectional synchronous electric push rod 504 drive the connecting rod 505 to move closer to the pressure plate 508. The two connecting rods 505 drive the two main drive rods 511 to move to opposite sides, reducing the distance between the two main drive rods 511. The two main drive rods 511, through the two main hinge plates 509 and the two secondary hinge plates 510, drive the secondary drive rods 513 to move away from the pressure plate 508, increasing the distance between the two secondary drive rods 513. The two secondary drive rods 513 drive the two pressing rollers 507 to move in opposite directions. At the same time, the two main drive rods 511 drive the two extension rods 514 to move to opposite sides. The two extension rods 514 drive the two side pressure plates 506 to move to opposite sides, reducing the distance between the two side pressure plates 506. The two side pressure plates 506 then compress the sides of the bagged fertilizer.

[0070] refer to Figure 11 and Figure 12 As shown, a threaded sleeve 519 is also fixed at the bottom of the crossbeam 503, and a central shaft 518 is movably connected below the threaded sleeve 519.

[0071] A gear 517 is fixed to the outer wall of the central shaft 518, and an extension rod 515 is provided on the outer wall of the main drive rod 511. A rack 516 that meshes with the gear 517 is fixed to the end of the extension rod 515 away from the main drive rod 511.

[0072] The extension rod 515 is sleeved on the upper half of the outer wall of the main drive rod 511. The upper half of the central shaft rod 518 is provided with a threaded part. The threaded sleeve 519 has a threaded hole in the middle that matches the threaded part. The gear 517 is located below the threaded part. When the two main drive rods 511 move towards the side closer to the central shaft rod 518, the two main drive rods 511 drive the two racks 516 to move towards the opposite side through the two extension rods 515. The two racks 516 mesh with the gear 517, causing the gear 517 to drive the central shaft rod 518 to rotate. The central shaft rod 518 drives the threaded part to rotate, so that the threaded part and the threaded hole cooperate to drive the central shaft rod 518 to move vertically up and down. The central shaft rod 518 drives the pressure plate 508 to move vertically downward. The pressure plate 508 presses the middle of the bagged fertilizer.

[0073] Two main drive rods 511 drive two racks 516 to move to opposite sides via two extension rods 515. The two racks 516 mesh with gears 517, causing gears 517 to drive the central shaft 518 to rotate. When the central shaft 518 rotates, the limiting rod 520 and the lug 521 cooperate to prevent the pressure plate 508 from rotating synchronously, thus ensuring the stable output of the rotation of the central shaft 518. The central shaft 518 drives the threaded part to rotate, so that the threaded part cooperates with the threaded hole to drive the central shaft 518 to move vertically up and down. The central shaft 518 drives the pressure plate 508 to move vertically downward, and the pressure plate 508 presses the middle of the bagged fertilizer.

[0074] Working principle:

[0075] When it is necessary to crush the clumps inside the bagged fertilizer, the two telescopic rods of the bidirectional synchronous electric push rod 504 retract synchronously. The telescopic rods of the bidirectional synchronous electric push rod 504 drive the connecting rod 505 to move closer to the pressure plate 508. The two connecting rods 505 drive the two main drive rods 511 to move towards each other, reducing the distance between the two main drive rods 511. The two main drive rods 511 are linked with the two auxiliary hinge plates 510 through the two main hinge plates 509, driving the auxiliary drive rods 513 to move away from the pressure plate 508 and away from each other, increasing the distance between the two auxiliary drive rods 513. The two auxiliary drive rods 513 synchronously drive the two crushing rollers 507 to move away from each other. At the same time, the two main drive rods 511 drive the two extension rods 514 to move towards each other. The two extension rods 514 drive the two side pressure plates 506 to move towards each other, reducing the distance between the two side pressure plates 506. The two side pressure plates 506 squeeze and limit the sides of the bagged fertilizer.

[0076] While the two main drive rods 511 move towards each other, the two extension rods 515 drive the two racks 516 to move towards each other, so that the two racks 516 mesh with the gear 517 for transmission, and then drive the central shaft 518 to rotate through the gear 517. During the rotation of the central shaft 518, the cooperation between the limiting rod 520 and the lug 521 forms a stop limit on the pressure plate 508, preventing the pressure plate 508 from rotating synchronously during the rotation of the central shaft 518, and ensuring the stable output of the rotation action of the central shaft 518. The central shaft 518 drives the threaded part to rotate synchronously, and through the threaded cooperation between the threaded part and the threaded hole, the rotational motion is converted into linear motion, driving the central shaft 518 to move back and forth in the vertical direction. The central shaft 518 drives the pressure plate 508 to move vertically upward, and the pressure plate 508 presses and limits the middle of the bagged fertilizer.

[0077] After the agglomeration and crushing of a single bag of fertilizer is completed, the piston rod of the electric hydraulic rod 502 drives the crossbeam 503 to move upward. The crossbeam 503 drives the bidirectional synchronous electric push rod 504 to move upward. The bidirectional synchronous electric push rod 504 drives the main drive rod 511 to move upward through the connecting rod 505. The main drive rod 511 drives the main hinge plate 509 and the secondary hinge plate 510 to move upward synchronously. The main hinge plate 509 and the secondary hinge plate 510 drive the side pressure plate 506 and the rolling roller 507 to move upward synchronously. At the same time, the crossbeam... 503 drives the main hinge plate 509 through the bidirectional synchronous electric push rod 504 and connecting rod 505. The main hinge plate 509 drives the pressure plate 508 to move upward synchronously, so that the side pressure plate 506, the crushing roller 507 and the pressure plate 508 all move above the fertilizer. Then, the traction block of the electric slide rail 501 drives the electric hydraulic rod 502 to move laterally to the corresponding station of the next bagged fertilizer to be processed. The above action process is repeated to complete the agglomeration crushing operation, realizing the continuous crushing treatment of agglomerated bagged fertilizer.

[0078] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
