Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for compound fertilizer preparation, specifically a compound fertilizer stacking device. Background Technology

[0002] In the preparation process of compound fertilizer, the prepared compound fertilizer needs to be bagged, and then the bagged compound fertilizer is regularly stacked on wooden pallets for subsequent storage or transportation. Referring to the existing Chinese patent with publication number CN220412707U, a stacking device for bagged compound fertilizer is disclosed, including a conveyor; a hoisting mechanism disposed at the output end of the conveyor; a lift disposed at the output end of the conveyor; a carrying platform rotatably mounted on the top of the lift, the carrying platform being used to place wooden brackets; a transmission rack, the transmission rack being ring-shaped and disposed at the bottom of the carrying platform; a transmission gear rotatably mounted on the top of the lift, the transmission gear meshing with the transmission rack; a vertical rack fixedly mounted on the bottom end of the lift; and a drive gear coaxially fixedly connected to the transmission gear, the drive gear meshing with the vertical rack.

[0003] The aforementioned stacking equipment for bagged compound fertilizer can simultaneously lower and rotate the wooden support frame via the loading platform, achieving a staggered 90° stacking between different layers. However, this stacking equipment still has some drawbacks. For example, the gripping mechanisms disclosed in the patent, whether clamping, forklifting, or suction cup types, are mostly designed and optimized for compound fertilizer bags of specific sizes and packaging materials, making it difficult to adapt to the diverse characteristics of bags in actual production. In actual operation, the sizes of compound fertilizer bags often vary, and the bag filling fullness is unstable. In this situation, a single gripping method is prone to gripping failure: if it is a clamping grip, too little clamping force will cause the bag to slip, while too much clamping force will easily damage the packaging, causing fertilizer leakage. In terms of load-bearing capacity, the weight of the entire layer of fertilizer (which may weigh hundreds of kilograms or even a ton) is entirely borne by the layer turntable mechanism. The selection of the slewing bearing (usually a slewing bearing) and drive mechanism (such as a worm gear motor or gear motor) below it must have a large margin, otherwise it is very easy to be overloaded and damaged.

The moving block is connected to one end of the lifting plate.

[0008] Preferably, the rotating assembly includes a first drive motor and a limiting ring. The first drive motor is installed in a first mounting frame and its output end is connected to a rotating plate. The limiting ring is disposed on one side of the first mounting frame, and the rotating plate has a rotating groove for the limiting ring to rotate.

[0009] Preferably, the adjustment mechanism includes a second mounting frame, a second drive motor, two adjustment plates and a gear disk. The second mounting frame is fixedly mounted on the rotating plate, the second drive motor is mounted on the second mounting frame and its output end is connected to the gear disk, the two adjustment plates are provided with toothed edges that mesh with the gear disk, and the rotating plate is provided with adjustment grooves for the adjustment plates to move.

[0010] Preferably, the clamping frame includes a support frame, a second support plate, a clamping plate, a second pressure sensor, and a rubber layer.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention effectively solves the problem of poor adaptability of existing equipment's gripping mechanisms by setting an adjustment mechanism between the clamping frame and the rotating plate, in conjunction with a first pressure sensor on the first support plate to monitor the load-bearing state of the placement plate. The adjustment mechanism can flexibly adjust the clamping spacing and position of the clamping frame according to the actual size and filling fullness of the compound fertilizer bags, avoiding the limitations of a single gripping method. At the same time, combined with pressure feedback, it can indirectly assist in judging the clamping force, reducing the situation where the bags slip due to insufficient clamping force or the packaging is damaged or the fertilizer leaks due to excessive clamping force, thus improving the adaptability and gripping safety of compound fertilizers with different characteristics. This invention changes the single load-bearing mode in existing equipment, where the weight of the entire layer of fertilizer is borne entirely by the layer turntable mechanism, by using a cooperative load-bearing structure of the first support plate and the placement plate, thus dispersing the load pressure during the stacking process. This design eliminates the need for a large size margin for the rotating bearings and drive mechanisms under the layer turntable, as required by existing technologies. This not only reduces the selection cost and installation space requirements of equipment components, but also reduces the risk of overload damage to the rotating bearings and drive mechanisms due to heavy loads, extending the overall service life of the equipment.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-5 This utility model provides a technical solution: A compound fertilizer stacking device, comprising: A first support plate 1 is provided, a first pressure sensor 2 is installed on the first support plate 1, a placement plate 3 is connected to the other side of the first pressure sensor 2, a telescopic rod 11 is provided between the first support plate 1 and the placement plate 3, and laser displacement sensors 12 are installed on all four sides of the placement plate 3. The wooden support frame for compound fertilizer is placed on the placement plate 3. At this time, the first pressure sensor 2 between the first support plate 1 and the placement plate 3 collects the weight data of the wooden support frame in real time and transmits it to the controller 32. The controller 32 judges whether the load-bearing status is normal based on the data. After confirming that there is no error, the equipment enters the standby state. In this process, the setting of the first pressure sensor 2 realizes the real-time collection and feedback of weight data, providing a basis for avoiding overload in subsequent stacking. At the same time, the laser displacement sensors 12 on the four sides of the placement plate 3 are activated simultaneously to locate the space above the placement plate 3 and transmit position data, providing a basis for subsequent stacking position calibration. Compared with existing equipment that lacks precise positioning function, the application of laser displacement sensors 12 can effectively improve the accuracy of subsequent stacking position and reduce the problem of stack shape deviation.

[0017] The base plate 4 is located on one side of the first support plate 1. A support column 6 is installed on the base plate 4 via a first electric slide rail 5. A lifting plate 7 is connected to the support column 6 via a lifting mechanism. The lifting mechanism includes a servo motor 13, a threaded rod 14, and a moving block 15. A moving groove 16 is provided on the support column 6. The threaded rod 14 is rotatably connected in the moving groove 16. The moving block 15 is threadedly connected to the threaded rod 14. The servo motor 13 is installed on the support column 6, and the output end of the servo motor 13 is connected to the extension end of the threaded rod 14 that passes through the moving groove 16. The moving block 15 is connected to one end of the lifting plate 7. A first mounting frame 9 is installed on the lifting plate 7 via a second electric slide rail 8. The controller 32 drives the first electric slide rail 5 on the base plate 4 to start, moving the support column 6 to the position to be grasped for the bagged compound fertilizer, completing the horizontal position adjustment. Subsequently, the controller 32 controls the servo motor 13 of the lifting mechanism on the support column 6 to start. The output end of the servo motor 13 drives the threaded rod 14 in the moving slot 16 to rotate. The moving block 15, which is threadedly connected to the threaded rod 14, then drives the lifting plate 7 to move up and down along the support column 6, adjusting the lifting plate 7 to a grasping height suitable for the bagged compound fertilizer. This adapts to different stacking layers and grasping height requirements, improving the efficiency and accuracy of the grasping preparation stage.

[0018] A rotating plate 10 is connected to the first mounting frame 9 via a rotating assembly. The rotating assembly includes a first drive motor 17 and a limiting ring 18. The first drive motor 17 is installed inside the first mounting frame 9, and the output end of the first drive motor 17 is connected to the rotating plate 10. The limiting ring 18 is located on one side of the first mounting frame 9, and a rotating groove 19 for the limiting ring 18 to rotate is provided on the rotating plate 10. A clamping frame is connected to the rotating plate 10 via an adjustment mechanism. The adjustment mechanism includes a second mounting frame 20, a second drive motor 21, two adjusting plates 22, and a gear disk 23. The second mounting frame 20 is fixedly mounted on the rotating plate 10, and the second drive motor 21 is mounted on the second mounting frame 20, with its output end connected to the gear disk 23. The two adjusting plates 22 have toothed edges that mesh with the gear disk 23. The rotating plate 10 has adjustment slots 24 for the adjusting plates 22 to move. The clamping frame includes a support frame. 25. A second support plate 26, a clamping plate 27, a second pressure sensor 28, and a rubber layer 29. A support frame 25 is connected to an adjusting plate 22. A second support plate 26 is connected to a support frame 25. A tilt angle is provided on one side of the second support plate 26. The second pressure sensor 28 is installed between the clamping plate 27 and the support frame 25. The rubber layer 29 is located on the side of the clamping plate 27 away from the second pressure sensor 28. Limiting rods 30 are provided at both ends of the clamping plate 27. A limiting groove 31 is provided on the support frame 25 for the limiting rods 30 to slide.

[0019] After the lifting plate 7 is adjusted into position, the controller 32 drives the second electric slide rail 8 on the lifting plate 7 to start, which moves the first mounting frame 9, so that the first mounting frame 9, connected to the rotating plate 10 and the clamping frame on the rotating plate 10 via the rotating assembly, approaches the bagged compound fertilizer, completing the alignment before gripping. Immediately afterwards, the controller 32 controls the second drive motor 21 of the adjustment mechanism to start. The output end of the second drive motor 21 drives the gear disk 23 to rotate. The gear disk 23 meshes with the teeth on the two adjusting plates 22, causing the adjusting plates 22 to move along the adjustment groove 24 of the rotating plate 10, thereby adjusting the distance between the two clamping frames to fit the current size of the bagged compound fertilizer. By flexibly adjusting the distance between the clamping frames, it can adapt to bagged compound fertilizers of different sizes and filling levels, greatly improving gripping adaptability. After the spacing adjustment is completed, the clamping frame continues to approach and contact the bagged compound fertilizer. At this time, the second pressure sensor 28 between the support frame 25 and the clamping plate 27 on the clamping frame will detect the clamping force data in real time and feed it back to the controller 32. The controller 32 adjusts the operation of the second drive motor 21 in real time according to the feedback data to stabilize the clamping force within a suitable range. At the same time, the rubber layer 29 on the side of the clamping plate 27 away from the second pressure sensor 28 can prevent the clamping plate 27 from directly contacting the packaging bag and prevent damage to the packaging bag. The second support plate 26 can support the compound fertilizer packaging bag, and the tilt angle on one side of the second support plate 26 can improve the gripping effect of the compound fertilizer packaging bag. The closed-loop feedback control of the second pressure sensor 28 effectively avoids the situation where the bag slips due to insufficient clamping force or the packaging is damaged or the fertilizer leaks due to excessive clamping force. The setting of the rubber layer 29 further improves the gripping safety and solves the gripping failure problem caused by the lack of force feedback control in existing equipment.

[0020] After the bagged compound fertilizer is picked up, the controller 32 coordinates the first electric slide rail 5, the lifting mechanism, and the second electric slide rail 8 to move the bagged compound fertilizer to the wooden bracket above the placement plate 3. If the stacking angle needs to be adjusted during the stacking process to achieve staggered stacking between different layers, the controller 32 will drive the first drive motor 17 of the rotating component on the first mounting frame 9 to start. The output end of the first drive motor 17 drives the rotating plate 10 to rotate. At the same time, the limiting ring 18 on one side of the first mounting frame 9 rotates synchronously in the rotating groove 19 of the rotating plate 10, providing limiting support for the rotating plate 10 and ensuring rotational stability until the bagged compound fertilizer is adjusted to a preset angle of 90° or 180°. This reduces the impact of transmission clearance on the rotation angle, ensures the accuracy of the rotation angle, avoids the problem of uneven stacking caused by the accumulation of long-term operating angle deviation, improves stacking regularity, and reduces the risk of bags tipping over during subsequent warehousing and transportation. After the angle adjustment is completed, controller 32 controls the adjustment mechanism to run in reverse, causing the clamping frame to release and the bagged compound fertilizer to be placed stably on the wooden support, completing the single-bag stacking. Repeat the above steps of gripping, transferring, rotating, and placing until the entire layer of stacking is completed.

[0021] In the above embodiment, a controller 32 is installed on the base plate 4. The controller 32 is electrically connected to the first pressure sensor 2, the first electric slide rail 5, the second electric slide rail 8, the laser displacement sensor 12, the servo motor 13, the first drive motor 17, the second drive motor 21, and the second pressure sensor 28.

[0022] It should be noted that the specific model specifications of the controller 32, the first pressure sensor 2, the first electric slide rail 5, the second electric slide rail 8, the laser displacement sensor 12, the servo motor 13, the first drive motor 17, the second drive motor 21, and the second pressure sensor 28 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.
