Description

Technical Field

[0001] This invention relates to the field of organic fertilizer filling technology, and in particular to an automatic organic fertilizer filling device and method. Background Technology

[0002] Organic fertilizers are derived from plants, animals, or natural minerals and are made through fermentation, composting, and other harmless treatment processes. They offer advantages such as improving soil structure, enhancing soil fertility, and promoting healthy crop growth, leading to their increasingly widespread application in modern agriculture. In large-scale production, organic fertilizers need to be packaged in bags using automated filling equipment for storage and transportation. However, organic fertilizers generally have a loose texture, uneven particle size, and poor flowability, posing significant technical challenges to their automated filling process.

[0003] Existing filling equipment typically uses gravity-feed combined with bag clamping for filling. This method reveals the following drawbacks in practical applications: loose fertilizer cannot be effectively compacted during free fall, resulting in large gaps and high loft within the bag, leading to a lower actual load per unit bag than the theoretical capacity. This not only reduces transportation efficiency but also increases packaging costs. Secondly, fertilizer granules naturally accumulate within the bag, easily forming localized voids or uneven density, causing the bag's center of gravity to shift. When the filled fertilizer bags are transferred on the conveyor, the uncompacted fertilizer and unstable center of gravity make them prone to tilting or even collapsing due to mechanical vibration or inertia, resulting in organic fertilizer spillage and contamination of the equipment and working environment. Therefore, there is an urgent need for an automated solution that can simultaneously achieve fertilizer compaction, uniform distribution, and center of gravity stability during the filling process to improve packaging quality and conveying reliability. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

A worm wheel is meshed on the worm gear, and a fixed shaft is fixedly disposed at the center of the worm wheel.

[0016] An automated filling method for organic fertilizer includes the following steps: S1, insert the opening of the fertilizer packaging bag into the discharge port of the filling machine, start the electric telescopic rod and drive the clamping plate to move relative to and press against the fertilizer packaging bag, so as to clamp the fertilizer packaging bag at the discharge port, and fill the organic fertilizer into the fertilizer packaging bag through the filling machine. S2, during the filling process, the servo motor is started to rotate in both directions, and its output end drives the worm and the bidirectional lead screw to rotate. S3, when the output end of the servo motor rotates in the forward direction, the double-acting screw drives the screw sleeve to move relative to each other, and drives the slide rod to move relative to each other. Then, the connecting rod pushes the push plate to move upward, so that the push plate contacts the fertilizer packaging bag and lifts the fertilizer packaging bag upward.

When the output end of the servo motor rotates in the forward direction, the clamping plate separates from the fertilizer packaging bag, which is used to realize the repeated squeezing of the organic fertilizer inside the fertilizer packaging bag. S5. After filling is completed, the electric push rod is started to drive the sealing plate to move relative to each other and clamp and seal the opening of the fertilizer packaging bag. At the same time, two sets of clamping plates are used to clamp the fertilizer packaging bag. Then the electric slide rail is started to move the fertilizer packaging bag onto the conveyor and transport it to the next process.

[0017] The beneficial effects of this invention are as follows: by cooperating with the drive unit and the push plate, the fertilizer packaging bag is lifted, causing the organic fertilizer to vibrate. Gravity compacts the organic fertilizer, reducing the gaps between fertilizer particles, preventing local voids, resulting in uniform density and increasing the actual loading capacity. At the same time, by cooperating with the drive unit and the sliding push rod, the clamping plate is moved relative to each other, squeezing and compacting the organic fertilizer in the lower half of the fertilizer packaging bag, further increasing the compaction degree of the organic fertilizer in the lower half of the fertilizer packaging bag. This not only increases the actual loading capacity but also lowers the center of gravity, improving stability. Attached Figure Description

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the invention.

[0029] Example 1 Reference Figures 1-3According to the first embodiment of the present invention, an automatic organic fertilizer filling device is provided, which includes: a filling machine 100, a conveyor 200 and a clamping mechanism 300. The clamping mechanism 300 is disposed at the discharge port of the filling machine 100 and is used to fix the fertilizer packaging bag to the discharge port of the filling machine 100. Two sets of clamping mechanisms 400 are symmetrically arranged on both sides of the fertilizer packaging bag. A shaking mechanism 500 is disposed below the fertilizer packaging bag.

[0030] In use, the fertilizer packaging bag is inserted into the discharge port of the filling machine 100, and the fertilizer packaging bag is clamped and positioned at the discharge port by the clamping mechanism 300. The organic fertilizer is then filled into the fertilizer packaging bag by the filling machine 100. At the same time, the drive unit and the push plate 503 work together to lift the fertilizer packaging bag and make it vibrate. Gravity compacts the organic fertilizer, reduces the gaps between fertilizer particles, prevents local voids, makes the density uniform, and increases the actual loading capacity. Meanwhile, the drive unit and the sliding push rod 504 work together to push the clamping plate 406 to move relative to each other, squeezing and compacting the organic fertilizer in the lower half of the fertilizer packaging bag, further increasing the compaction degree of the organic fertilizer in the lower half of the fertilizer packaging bag. This not only increases the actual loading capacity but also lowers the center of gravity and improves stability.

The clamping plate 303 is set to be arc-shaped to match the shape of the outlet, and the contact surface with the fertilizer packaging bag is set to be frosted to increase friction and ensure that the fertilizer packaging bag will not slip during the filling stage.

[0032] Furthermore, refer to Figure 2 , Figure 3The clamping mechanism 400 also includes an electric slide rail 401, on which a vertical plate 402 is fixedly mounted via a slider. The electric slide rail 401 moves the vertical plate 402 via the slider. An electric push rod 403 is fixedly mounted on one side of the vertical plate 402. The telescopic end of the electric push rod 403 is fixedly connected to the sealing plate 404. After filling, the electric push rod 403 moves the sealing plate 404 relative to each other and abuts against each other, clamping and sealing the opening of the fertilizer packaging bag. A movable block 4 is fixedly mounted on one side of the clamping plate 406. 05. The movable block 405 is slidably inserted into the inner wall of the vertical plate 402, and a limiting block is fixedly provided at the end of the movable block 405 away from the clamping plate 406. The clamping plate 406 is slidably inserted into the vertical plate 402 through the movable block 405. A positioning plate 407 is fixedly provided on the movable block 405. A sliding groove 407a is provided on the positioning plate 407, and one end of the sliding push rod 504 abuts in the sliding groove 407a. When the sliding push rod 504 moves, it pushes the positioning plate 407 to move simultaneously, and then drives the clamping plate 406 to move.

[0033] Furthermore, refer to Figure 4 The shaking mechanism 500 also includes a base plate 501 and a base box 502 fixedly connected to the base plate 501. A through hole matching the push plate 503 is opened at the center of the base plate 501.

[0034] Preferred, refer to Figures 4-6 The drive unit includes a bidirectional lead screw 506 located in the base box 502. Two lead screw sleeves 507 are fitted on the bidirectional lead screw 506 and are threadedly connected to the bidirectional lead screw 506. When the bidirectional lead screw 506 rotates, it drives the lead screw sleeves 507 to move axially. A slide rod 508 is fixedly installed on the lead screw sleeves 507. The slide rod 508 is moved by the lead screw sleeves 507. A connecting rod 509 is rotatably installed at the other end of the slide rod 508. The other end of the connecting rod 509 is rotatably connected to the push plate 503. The slide rod 508 and the connecting rod 509 can drive the push plate 503 to move up and down. A limit hole is opened on the base box 502. One end of the slide rod 508 passes through the limit hole and slides in the limit hole to limit the circumferential rotation of the lead screw sleeve 507.

[0035] Preferred, refer to Figures 4-6The drive unit also includes two worm gears 510 rotatably mounted inside the base box 502. Worm gears 511 are meshed with the worm gears 510. When the worm gears 510 rotate, they drive the worm gears 511 to rotate. A fixed shaft is fixedly mounted at the center of the worm gears 511, and ball screws 512 are fixedly mounted at both ends of the fixed shaft. The worm gears 511 drive the ball screws 512 to rotate via the fixed shaft. One end of the ball screw 512 is rotatably mounted on the inner wall of the base box 502, and a ball screw thread is fitted onto the ball screw 512. The ball screw nut 513 is threadedly connected to the ball screw 512. The ball screw nut 513 is driven to move axially through the ball screw 512. One end of the sliding push rod 504 is fixedly connected to the ball screw nut 513. The ball screw nut 513 drives the sliding push rod 504 to move. Limiting holes 2 are provided on the base plate 501 and the base box 502. The sliding push rod 504 passes through the limiting hole 2 and slides in the limiting hole 2 to limit the circumferential rotation of the ball screw nut 513.

[0036] Among them, reference Figure 4 , Figure 5 The drive unit also includes a servo motor 505 fixedly mounted on one side of the base box 502. The output end of the servo motor 505 extends into the base box 502 and is fixedly connected to the worm gear 510. The two ends of the bidirectional lead screw 506 are fixedly connected to the worm gear 510 respectively. The servo motor 505 synchronously drives the worm gear 510 and the bidirectional lead screw 506 to rotate.

[0037] In use, the servo motor 505 is started, and its output end drives the worm gear 510 and the bidirectional lead screw 506 to rotate. The bidirectional lead screw 506 drives the lead screw sleeve 507 and the slide rod 508 to move, and in conjunction with the connecting rod 509, drives the push plate 503 to move up and down, shaking the fertilizer packaging bag up and down. At the same time, the worm gear 510 drives the worm wheel 511 to rotate, the worm wheel 511 drives the ball screw 512 to rotate, the ball screw 512 drives the ball screw nut 513 and the sliding push rod 504 to move, and in conjunction with the positioning plate 407, drives the clamping plate 406 to move, and the clamping plate 406 squeezes and compacts the organic fertilizer in the lower half of the fertilizer packaging bag.

[0038] Example 3 A method for using an automatic organic fertilizer filling device, based on Examples 1 and 2, includes the following steps: S1, insert the opening of the fertilizer packaging bag into the discharge port of the filling machine 100, start the electric telescopic rod 302 and drive the clamping plate 303 to move relative to and press against the fertilizer packaging bag, so as to clamp the fertilizer packaging bag at the discharge port, and fill the organic fertilizer into the fertilizer packaging bag through the filling machine 100. S2, During the filling process, the servo motor 505 is started to rotate in both directions, and its output end drives the worm gear 510 and the bidirectional lead screw 506 to rotate. S3, when the output end of the servo motor 505 rotates in the forward direction, the double-acting lead screw 506 drives the lead screw sleeve 507 to move relative to each other, and drives the slide bar 508 to move relative to each other. Then, the connecting rod 509 pushes the push plate 503 to move upward, so that the push plate 503 contacts the fertilizer packaging bag and lifts the fertilizer packaging bag upward. When the servo motor 505 rotates in the reverse direction, the push plate 503 moves downward and separates from the fertilizer packaging bag, which is used to realize the repeated shaking of the fertilizer packaging bag. S4. At the same time, when the output end of the servo motor 505 rotates in the reverse direction, the worm gear 510 drives the worm wheel 511 to rotate, which in turn drives the ball screw 512 to rotate. The ball screw 512 drives the ball screw nut 513 and the sliding push rod 504 to move, which, together with the positioning plate 407, pushes the two sets of clamping plates 406 to move relative to each other and to contact the fertilizer packaging bag. When the output end of the servo motor 505 rotates in the forward direction, the clamping plate 406 separates from the fertilizer packaging bag, which is used to realize the repeated squeezing of the organic fertilizer inside the fertilizer packaging bag. S5. After filling is completed, start the electric push rod 403 to drive the sealing plate 404 to move relative to each other and clamp and seal the opening of the fertilizer packaging bag. At the same time, cooperate with two sets of clamping plates 406 to clamp the fertilizer packaging bag. Then start the electric slide rail 401 to move the fertilizer packaging bag onto the conveyor 200 and transport it to the next process.

[0039] In summary, this method, through coordinated motion control driven by a single motor, simultaneously achieves a two-way action during the filling process: the reciprocating lifting and shaking of the pusher plate and the periodic lateral squeezing of the clamping plate. This sequential coordination effectively promotes the dense filling and uniform distribution of organic fertilizer within the bag, significantly increasing the loading capacity and ensuring a stable center of gravity, thus reducing the risk of tipping over during transport. Furthermore, by integrating filling, synchronous compaction, and transfer functions, it achieves efficient and stable automated operation.

[0040] It should be noted that the filling machine 100 is a standard packaging machine, such as the automatic weighing packaging machine produced by Wuxi Maijie Machinery, which has the functions of automatic weighing and quantitative feeding; the conveyor 200 is a standard belt conveyor with adjustable conveying speed, and baffles can be installed on both sides of the conveyor 200 to play a certain limiting role.

[0041] It is worth noting that the entire device is controlled by a controller. For example, a photoelectric sensor detects whether the fertilizer bag has reached the designated position and transmits the signal to the controller. The controller then issues control commands to the electric push rod 403 to clamp the fertilizer bag. Since the controller is a commonly used device and represents mature existing technology, its electrical connections and specific circuit structure will not be elaborated upon here.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.

S3, when the output end of the servo motor (505) rotates in the forward direction, the screw sleeve (507) is driven to move relative to the bidirectional screw (506), and the slide bar (508) is driven to move relative to the slide bar. Then, the push plate (503) is pushed upward through the connecting rod (509), so that the push plate (503) contacts the fertilizer packaging bag and lifts the fertilizer packaging bag upward. When the servo motor (505) rotates in the reverse direction, the push plate (503) moves downward and separates from the fertilizer packaging bag, which is used to realize the repeated shaking of the fertilizer packaging bag. S4. At the same time, when the output end of the servo motor (505) rotates in the reverse direction, the worm gear (510) drives the worm wheel (511) to rotate, and drives the ball screw (512) to rotate. The ball screw (512) drives the ball screw nut (513) and the sliding push rod (504) to move. In conjunction with the positioning plate (407), the two sets of clamping plates (406) move relative to each other and come into contact with the fertilizer packaging bag. When the output end of the servo motor (505) rotates in the forward direction, the clamping plate (406) separates from the fertilizer packaging bag, which is used to realize the repeated squeezing of the organic fertilizer in the fertilizer packaging bag. S5. After filling is completed, start the electric push rod (403) to drive the sealing plate (404) to move relative to each other and clamp and seal the opening of the fertilizer packaging bag. At the same time, cooperate with two sets of clamping plates (406) to clamp the fertilizer packaging bag. Then start the electric slide rail (401) to move the fertilizer packaging bag to the conveyor (200) and transport it to the next process.
