Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1

[0042] like Figures 1-3 As shown;

[0043] An automatic fertilizer raw material feeding system includes a placement plate 20, a lifting assembly 30, and a feeding assembly 60. A conveyor 10 is arranged on the left side of the placement plate 20. Baffles 11 are symmetrically arranged on the upper surface of the conveyor 10. Multiple rollers 12 are rotatably connected in the through groove of the baffles 11. A surrounding plate 22 is fixedly arranged on the upper surface of the placement plate 20. A weighing device 21 is arranged on the upper surface of the placement plate 20 and inside the surrounding plate 22. A controller 23 is arranged on the front surface of the surrounding plate 22.

[0044] The lifting assembly 30 includes a first cylinder 31, a support plate 32, a second cylinder 33, a hook plate 34, and a first motor 35. The first cylinder 31 is mounted on a track. Multiple support plates 32 are rotatably connected to the outer side wall of the telescopic shaft of the first cylinder 31. A fixed rod is fixedly connected to the bottom end of the telescopic shaft of the first cylinder 31. Multiple second cylinders 33 are rotatably connected to the outer side wall of the fixed rod, and their telescopic shafts are rotatably connected to the support plate 32. The hook plate 34 is rotatably connected to the end face groove of the support plate 32 through a rotating shaft. The first motor 35 is fixedly installed on the side of the support plate 32, and the output shaft of the first motor 35 is fixedly connected to the rotating shaft.

[0045] The feeding assembly 60 includes a feeding cylinder 61, a bracket 62, a third cylinder 63, a fourth cylinder 64, a scraper 65, and a fifth cylinder 68. The feeding cylinder 61 is located below the track and to the right of the placement plate 20. The bracket 62 is installed at the bottom of the feeding cylinder 61. The third cylinder 63 is installed on the bottom surface of the bracket 62. The telescopic shaft of the third cylinder 63 passes through the bracket 62. The fourth cylinder 64 is installed on the telescopic shaft of the third cylinder 63. Multiple scrapers 65 are rotatably connected to the bottom of the fourth cylinder 64. The fourth cylinder 64 has a receiving groove 67 inside. The fifth cylinder 68 is rotatably connected inside the receiving groove 67. The telescopic shaft of the fifth cylinder 68 is rotatably connected to the scraper 65.

[0046] It also includes an auxiliary lifting assembly 50 disposed between the placement plate 20 and the feed cylinder 61;

[0047] The auxiliary lifting assembly 50 includes a bracket 51, a support plate 52, a mounting plate 53, a vertical plate 54, a limiting plate 55, a second motor 56, a rotating rod 57, and a conveyor belt 58. The bracket 51 has a frame structure. The support plate 52 is slidably connected inside the support plate 52. Two rotating rods 57 are rotatably connected to both ends of the inner sidewall of the support plate 52, and the two are connected by transmission through the conveyor belt 58. The support plate 52 is fixedly connected to the conveyor belt 58 through the mounting plate 53. The vertical plate 54 is fixedly installed on the lower surface of the mounting plate 53. The limiting plate 55 is symmetrically fixed on the inner sidewall of the bracket 51. The surface of the vertical plate 54 is provided with a groove, and the limiting plate 55 is located in the groove.

[0048] In this implementation plan: the conveyor 10 transports the bags one by one to the placement plate 20. The baffle 11 limits the movement of the bags to prevent them from tilting, and in conjunction with the roller 12, it increases the smoothness of transportation. The weighing device 21 weighs the fertilizer raw materials inside the bags and sends the weight back to the display screen of the controller 23. The surrounding plate 22 acts as a barrier. The power source of the track moves the first cylinder 31 to directly above the placement plate 20. The telescopic shaft of the first cylinder 31 extends, driving the support plate 32 downward. At this point, the telescopic shaft of the second cylinder 33 is in a retracted state, the four support plates 32 are aligned with the four handles of the material bag, the telescopic shaft of the second cylinder 33 extends, opening the four support plates 32 and lifting the material bag. The telescopic shaft of the first cylinder 31 retracts, and when it moves above the bracket 51 in conjunction with the power source of the track, the second motor 56 is started by the controller 23. This, along with the rotating rod 57 and the conveyor belt 58, drives the bracket 52 to move synchronously with the support plates 32, providing support during the lifting and moving of the material bag. The function is to prevent the material bag from falling or moving unstably. The mounting plate 53 ensures the firmness of the connection between the pallet 52 and the conveyor belt 58. The limiting plate 55 is inserted into the interior of the upright plate 54, which plays a certain role in supporting the pallet 52 and ensuring the supporting effect of the pallet 52. When the material bag moves to the top of the feed cylinder 61, the material bag enters the interior of the feed cylinder 61 to reduce the dispersion of dust. At this time, the third cylinder 63 on the bracket 62 is activated. The telescopic shaft of the third cylinder 63 drives the fourth cylinder 64 to insert. At the bottom of the feed bag, the top of the fourth cylinder 64 is cone-shaped, making it easy to puncture. At the same time, the multiple scrapers 65 are hook-shaped and sharp, which, together with the fourth cylinder 64, create an explosive puncture at the bottom of the feed bag. After being inserted into the feed bag, the fifth cylinder 68 in the receiving groove 67 is activated. The telescopic shaft of the fifth cylinder 68 drives the scrapers 65 to unfold and causes the fourth cylinder 64 to retract, widening the explosive gap. This allows the feed bag to be fed from the center, avoiding any residue inside the feed bag.

[0049] It should be noted that the outer wall of the rotating rod 57 has teeth, and the inner wall of the conveyor belt 58 has grooves. The teeth and grooves are matched with each other to increase the motion force generated by the conveyor belt 58.

[0050] It should be noted that the surface of the support 62 has a prismatic structure, so there will be no raw material residue on the support 62. The interior of the container 67 is interconnected, so if raw material falls into the interior of the container 67, it is easy to discharge the raw material.

[0051] like Figure 1 and Figure 3 As shown;

[0052] In an optional embodiment, the bottom surface of the upright plate 54 is rotatably connected with a plurality of rollers, and the rollers are in contact with the bottom surface of the inner sidewall of the bracket 51.

[0053] In this embodiment, multiple rollers reduce the difficulty of moving the pallet 52 and enhance the supporting effect of the pallet 52 on the material bag.

[0054] In an optional embodiment, a closing assembly 40 is also provided at the top end of the telescopic shaft of the first cylinder 31;

[0055] The sealing assembly 40 includes a cover plate 41, an extension plate 42, a pusher 43, and a retaining plate 45. The cover plate 41 is fixedly disposed on the top of the telescopic shaft of the first cylinder 31, and an inner groove is provided on its end face. The pusher 43 is fixedly disposed in the inner groove. The retaining plate 45 is fixedly disposed on the telescopic shaft of the pusher 43. The telescopic shaft of the pusher 43 is fixedly connected to the extension plate 42 through the retaining plate 45.

[0056] In this embodiment: when the material bag enters the interior of the feeding cylinder 61, the telescopic shaft of the pusher 43 inside the cover plate 41 drives the clamping plate 45 to extend, thereby extending the extension plate 42, which plays a certain role in sealing the top of the feeding cylinder 61, reducing the overflow of dust during feeding.

[0057] It should be noted that the pusher 43 is an electrical component that can extend and retract, and is connected to the controller 23 by signal.

[0058] In an optional embodiment, the enclosure assembly 40 further includes a connecting layer 44, which is fixedly connected between the cover plate 41 and the extension plate 42 and on both sides of the inner groove.

[0059] In this embodiment, the connecting layer 44 is made of elastic material, which can re-close the gap between the cover plate 41 and the extension plate 42, providing a more enclosed space for material feeding and preventing dust from overflowing.

[0060] like Figures 4-6 As shown;

[0061] In an optional embodiment, the inner sidewall of the feed cylinder 61 is symmetrically provided with first slots 66, the extension plate 42 and the first slots 66 are adapted to each other, and the bottom end of the first slots 66 is connected to a guide groove.

[0062] In this embodiment, the extension plate 42 is inserted into the first slot 66, which not only provides support for the entire lifting assembly 30 and the pressure brought by the material bag, but also helps to close the space.

[0063] In an optional embodiment, a material shaking assembly 80 is further included, symmetrically arranged on the inner sidewall of the feeding cylinder 61;

[0064] The material shaking assembly 80 includes a second electric push rod 81, a shaking plate 83, a spring 85, and a plate 86. The second electric push rod 81 is installed on the outer wall of the feeding cylinder 61. The extension and retraction of the second electric push rod 81 passes through the feeding cylinder 61 and the shaking plate 83 is installed through a ball clamp. Multiple springs 85 are fixedly connected to the end face of the shaking plate 83, and the plate 86 is fixedly connected to the end face of the springs 85.

[0065] In this embodiment: when the feeding is nearing its end, the second electric push rod 81 drives the shaking plate 83 to push inward repeatedly, accelerating the falling of any remaining raw materials in the bag. In addition, the multiple springs 85, in conjunction with the bouncing of the plate 86, accelerate the shaking of the shaking plate 83, which helps to speed up the falling speed.

[0066] It should be noted that the shaking plate 83 is fixedly connected to the telescopic shaft of the second electric push rod 81 through the ball clamp, so that the shaking plate 83 can swing, which is beneficial to enhance the bounce of the plate 86 and to shake the material.

[0067] In an optional embodiment, the material shaking assembly 80 includes a vibration motor 84, a plurality of vibration motors 84 are installed inside the shaking plate 83, and the material discharge cylinder 61 has a groove 82 on the side near the shaking plate 83.

[0068] In this embodiment: the vibration force generated by the vibration motor 84 further enhances the shaking force generated by the shaking plate 83, avoiding any residue. The cumulative thickness of the groove 82 and the shaking plate 83, the spring 85 and the plate 86 are matched. The groove 82 can hide the three components, preventing them from being crushed during the initial feeding and facilitating the shaking of materials later.

[0069] like Figure 1 As shown;

[0070] In an optional embodiment, a storage component 70 is further provided on the right side of the unloading component 60. The storage component 70 includes a storage box 71, a third motor 73, a sealing plate 74, a first electric push rod 75, and a push plate 76. The storage box 71 is located on the right side of the unloading cylinder 61 and below the track. The third motor 73 is installed on the rear surface of the storage box 71. A storage groove is provided on the inner side wall of the storage box 71. The sealing plate 74 is rotatably connected to the storage groove through a rotating rod. The output shaft of the third motor 73 is rotatably connected to the rotating rod. The first electric push rod 75 is fixedly provided on the left side of the storage box 71, and its telescopic shaft passes through the storage box 71 and is fixedly connected to the push plate 76.

[0071] In this embodiment: After the shaking is completed, the bag moves along the track to the top of the storage box 71. The second cylinder 33 retracts and cooperates with the first motor 35 to open the hook plate 34, so that the bag falls into the inside of the storage box 71. At this time, the sealing plate 74 is located inside the storage groove, so that the bag falls to the bottom of the storage box 71. When the amount is accumulated to a certain level, the third motor 73 drives the sealing plate 74 to rotate to the horizontal. The first electric push rod 75 drives the push plate 76 to push, which, together with the sealing plate 74, compresses the amount of bag into a square shape, which is convenient for later recycling.

[0072] It should be noted that the third motor 73 has a self-locking structure to ensure the horizontal position of the first electric push rod 75, which facilitates its use with the push plate 76.

[0073] It should be noted that the first motor 35 has a self-locking structure to ensure that the support plate 32 supports the material bag.

[0074] In an optional embodiment, the storage assembly 70 further includes a guide plate 77, and the inner sidewall of the storage box 71 is symmetrically provided with a second slot 72, and the inner sidewall of the second slot 72 is fixedly provided with the guide plate 77.

[0075] In this embodiment: the guide plate 77 has a triangular structure, which facilitates the guidance and falling of the bag. The end face of the sealing plate 74 is in contact with the guide plate 77, and the end face of the sealing plate 74 is friction-resistant, which increases the friction between it and the guide plate 77 and is beneficial to the stability of the sealing plate 74. The second slot 72 and the first slot 66 have the same structure, and the sealing component 40 can seal the storage box 71. Dust is generated during compression.

[0076] It should be noted that the storage box 71 has a door panel on the right side, which makes it easy to open and take out the compressed material bag.

[0077] It should be noted that in this embodiment, as... Figure 6 As shown in the figure, all the structures are connected to the controller 23 via signal, which facilitates the control of the structure through the controller 23. The power source starter of the track is also connected to the controller 23 via signal, which facilitates the positioning of the first cylinder 31 and realizes integrated intelligent development.

[0078] The working principle and usage process of this invention: The conveyor 10 transports the bags one by one to the placement plate 20. The baffle 11 limits the position of the bags to prevent them from tilting, and in conjunction with the roller 12, it increases the smoothness of transportation. The weighing device 21 weighs the fertilizer raw materials inside the bags and sends the weight back to the display screen of the controller 23. The surrounding plate 22 acts as a barrier. The power source of the track moves the first cylinder 31 directly above the placement plate 20. The telescopic shaft of the first cylinder 31 extends, driving the support plate 32 to move downward. At this time, the telescopic shaft of the second cylinder 33 is in a retracted state. The four support plates 32 are aligned with the four handles of the bags. When the telescopic shaft of cylinder 31 extends, it opens the four support plates 32, lifting the material bag. The telescopic shaft of cylinder 31 retracts, and when the power source of the track moves above the bracket 51, the controller 23 starts the second motor 56. This, along with the rotating rod 57 and conveyor belt 58, drives the support plate 52 to move synchronously with the support plates 32. This provides support during the lifting and moving of the material bag, preventing it from falling or becoming unstable. The mounting plate 53 ensures the secure connection between the support plate 52 and the conveyor belt 58. The limiting plate 55 engages inside the upright plate 54, providing support for the support plate 52 and ensuring its effectiveness. When the bag moves above the feeding cylinder 61, it enters the interior of the feeding cylinder 61, reducing dust dispersion. As the bag enters the feeding cylinder 61, the telescopic shaft of the pusher 43 inside the cover plate 41 drives the clamping plate 45 to extend, which in turn extends the extension plate 42, providing a certain degree of sealing to the top of the feeding cylinder 61. This reduces dust spillage during feeding. The connecting layer 44 is made of elastic material, further sealing the gap between the cover plate 41 and the extension plate 42, providing a more enclosed space for feeding and preventing dust spillage. The extension plate 42 inserts into the first clamping slot 66, providing support not only for the entire lifting assembly 30 but also for the pressure exerted by the bag. The function of the third cylinder 63 on the support 62 is to facilitate the sealing of the space. At this time, the telescopic shaft of the third cylinder 63 drives the fourth cylinder 64 to insert into the bottom of the bag. Since the top of the fourth cylinder 64 is cone-shaped, it is easy to pierce. At the same time, since the multiple scrapers 65 are hook-shaped and sharp, they work with the fourth cylinder 64 to create an explosive piercing at the bottom of the bag. After being inserted into the bag, the fifth cylinder 68 in the trough 67 is activated. The telescopic shaft of the fifth cylinder 68 drives the scraper 65 to unfold and causes the fourth cylinder 64 to contract, expanding the explosive gap, so that the bag is fed from the center, avoiding the situation of residue inside the bag.

[0079] As the feeding process nears its end, the second electric push rod 81 drives the shaking plate 83 to repeatedly push inward, accelerating the descent of any remaining material in the bag. Multiple springs 85, in conjunction with the bouncing action of the mounting plate 86, further accelerate the shaking of the shaking plate 83, facilitating faster descent. The vibration force generated by the vibrating motor 84 further enhances the shaking force of the shaking plate 83, preventing any residue. The limiting groove and the combined thickness of the shaking plate 83, springs 85, and mounting plate 86 are matched, allowing them to be concealed during the initial feeding process and facilitating subsequent shaking. After shaking, the bag moves along the track to the top of the storage box 71. The second cylinder 33 retracts, coordinating with the first motor 35 to open the hook plate 34, causing the bag to fall into the storage box 71. At this point, the sealing plate... 74 is located inside the storage trough, allowing the material bags to fall to the bottom of the storage box 71. When the material bag reaches a certain quantity, the third motor 73 drives the sealing plate 74 to rotate to a horizontal position, and the first electric push rod 75 drives the push plate 76 to push. Together with the sealing plate 74, the material bag of a certain quantity is compressed into a square shape, which is convenient for later recycling. The guide plate 77 has a triangular structure, which facilitates the guidance and falling of the material bag. The end face of the sealing plate 74 is in contact with the guide plate 77, and the end face of the sealing plate 74 is friction-resistant, which increases the friction between it and the guide plate 77 and is conducive to the stability of the sealing plate 74. The second slot 72 has the same structure as the first slot 66 and can seal the storage box 71 through the sealing component 40. Dust is generated during compression. The electrical structure is controlled by the controller 23 to realize intelligent operation.

[0080] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
