Description

Technical Field

[0001] The invention relates to the technical field of packaging, and more particularly to a metering and packaging device for producing organic fertilizers. Background Art

[0002] With the development of organic agriculture, organic fertilizers are widely used due to their environmentally friendly properties. However, organic fertilizers are generally sticky, highly humid, and prone to agglomeration. During the packaging process, they easily adhere to the inner walls of conveying pipes, causing frequent blockages in traditional continuous filling equipment.

[0003] In existing technologies, packaging devices mostly use a vertical drop continuous filling mode. Organic fertilizers fall freely under the action of gravity, lacking a dynamic dredging mechanism. Viscous materials easily form an arch bridge effect at the point where the pipe diameter changes, causing flow channel blockage. Especially when the equipment is running for a long time, the residual fertilizer on the inner wall of the pipe gradually hardens, further increasing the risk of blockage, requiring frequent shutdowns for cleaning, and seriously affecting production efficiency.

[0004] In addition, traditional equipment lacks a compaction process, and the loose fertilizer is unevenly piled in the barrel, resulting in a high void ratio after packaging, which not only increases transportation costs but also easily causes the barrel to deform and rupture due to uneven internal stress. The above defects have, to a certain extent, restricted the efficiency and quality stability of large-scale production of organic fertilizers. Summary of the Invention

[0005] In order to overcome the above technical problems, the present invention proposes a metering and packaging device for organic fertilizer production.

[0044] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed solely to enable those skilled in the art to better understand and implement the subject matter described herein, and that the functions and arrangements of the elements discussed may be varied without departing from the scope of this specification. Various examples may omit, substitute, or add various processes or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

[0045] See also Figure 1 The present invention discloses a metering and packaging device for organic fertilizer production, which is used to meter and pack organic fertilizer into a packaging barrel 100. The packaging barrel 100 includes a barrel body 110, a barrel mouth 120 is provided at the upper end of the barrel body 110, an annular recessed portion 130 is provided on the outer side of the barrel mouth 120, and a plurality of lifting belts 140 are provided on the outer circumference of the barrel body 110.

[0046] See also Figure 2 、 Figure 3 and Figure 4 The metering and packaging device includes a packaging table 200 for placing the packaging barrel 100 and a stand 300 located directly above the packaging table 200, and also includes a metering unit 400, a connecting unit 500, a clamping unit 600 and a dredging unit 700. The metering unit 400 is arranged on the stand 300 for measuring and quantitatively distributing the organic fertilizer; the upper end of the connecting unit 500 is connected to the outlet end of the metering unit 400, including an inner rigid tube 510 fixed on the stand 300 and a threaded hose 520 fixedly sleeved on the outside of the inner rigid tube 510, and the lower end of the threaded hose 520 is connected to an outer rigid tube 530 adapted to the barrel mouth 120; the clamping unit 500 is connected to the outer rigid tube 530 and the outer rigid tube 530 is connected to the barrel mouth 120; the clamping unit 500 is connected to the outer rigid tube 530 and the outer rigid tube 530 is connected to the outer rigid tube 530. The element 600 is mounted on the platform 300 and includes a lifting cylinder 610 fixed to the platform 300 and a lifting frame 620 connected to the output end of the lifting cylinder 610. The outer rigid tube 530 is fixed to the center of the lifting frame 620. The lifting frame 620 is also provided with a barrel mouth connector 630 adapted to the annular recess 130 at the center. The lifting frame 620 is circumferentially provided with a plurality of lifting belt connectors 640 adapted to the corresponding lifting belts 140. The dredging unit 700 includes a fan 710 fixed to the platform 300 and an air pipe 720 connected to the output end of the fan 710. The air pipe 720 passes through and vertically extends into the inner rigid tube 510.

[0047] Specifically, an empty packaging barrel 100 is placed on the packaging table 200, and the barrel mouth 120 of the packaging barrel 100 is located directly below the outer rigid tube 530. The lifting cylinder 610 drives the lifting frame 620 downward until the outer rigid tube 530 is inserted into the barrel mouth 120 and the barrel mouth connector 630 reaches the same height as the annular recess 130. The barrel mouth connector 630 is adapted to the annular recess 130 to seal the barrel mouth 120 and the outer rigid tube 530. Then, each lifting strap 140 is connected to the corresponding lifting strap connector 640, and the packaging barrel 100 and the clamping unit 600 are clamped and fixed.

[0048] The organic fertilizer is quantitatively weighed in multiple batches by the metering unit 400. The measured fertilizer enters the barrel body 110 in batches through the inner rigid tube 510 and the outer rigid tube 530. As the fertilizer falls, the reciprocating extension and contraction of the lifting cylinder 610 drives the lifting frame 620 to move up and down, thereby periodically pulling the lifting belt 140 upward through each group of lifting belt connectors 640, causing the bottom of the packaging barrel 100 to periodically hit the packaging table 200, thereby compacting the fertilizer entering the barrel body 110 in batches and improving the filling density of the organic fertilizer in the barrel body 110.

[0049] During the process of loading the organic fertilizer in batches, the fan 710 is turned on to blow air into the inner rigid tube 510. During the reciprocating lifting of the lifting frame 620, the outer rigid tube 530 also periodically rises and falls relative to the inner rigid tube 510. The threaded hose 520 adaptively adjusts its expansion and contraction. When the outer rigid tube 530 periodically rises and falls, the outer rigid tube 530 and the air pipe 720 in the inner rigid tube 510 also produce relative movement, so that the airflow ejected from the air pipe 720 is used to blow and guide the fertilizer in the outer rigid tube 530, thereby avoiding accumulation and blockage of organic fertilizer in the outer rigid tube 530, thereby improving the smoothness of fertilizer filling.

[0050] It should be noted that, during the batch filling process of the organic fertilizer, the reciprocating extension and retraction of the lifting cylinder 610 drives the lifting frame 620 to move reciprocatingly, and the lifting belt 140 is periodically pulled upward by the lifting belt connector 640, so that the bottom of the packaging barrel 100 periodically hits the packaging table 200, thereby compacting the fertilizer entering the barrel body 110 in batches, effectively improving the filling density of the organic fertilizer in the barrel body 110, reducing the gaps in the fertilizer in the packaging barrel 100, improving the utilization rate of the packaging space, and also avoiding the risk of packaging deformation and rupture due to loose fertilizer.

[0051] During the fertilizer filling process, the fan 710 blows air into the inner rigid tube 510 through the air pipe 720, and uses the air flow to blow and dredge the fertilizer in the outer rigid tube 530; when the outer rigid tube 530 periodically rises and falls, the air pipe 720 and the outer rigid tube 530 generate relative movement, further enhancing the dredging effect of the air flow, effectively preventing the accumulation and blockage of organic fertilizer in the outer rigid tube 530, ensuring the smoothness of fertilizer filling and improving the filling efficiency;

[0052] The lifting frame 620 is driven downward by the lifting cylinder 610 to achieve precise docking of the outer rigid tube 530 with the barrel mouth 120 of the packaging barrel 100. The barrel mouth connector 630 is adapted to the annular recessed portion 130 to seal the barrel mouth 120 with the outer rigid tube 530, ensuring that the fertilizer will not leak out during the filling process. At the same time, the connection between the lifting belt connector 640 and the lifting belt 140 achieves a secure clamping of the packaging barrel 100 and the clamping unit 600, ensuring the stability and reliability of the entire filling process and preventing the packaging barrel 100 from shifting or tipping over during the filling process.

[0053] The metering unit 400 can quantitatively weigh multiple batches of organic fertilizer, ensuring that the weight of the fertilizer loaded each time is accurate and consistent, effectively improving the accuracy of fertilizer packaging, avoiding fertilizer waste and substandard packaging weight, and improving the stability of product quality;

[0054] The combined design of the inner rigid tube 510 and the threaded hose 520 enables the fertilizer to be stably and smoothly transferred from the metering unit 400 to the packaging barrel 100. The elastic and telescopic characteristics of the threaded hose 520 can adapt to the periodic lifting and lowering movement of the outer rigid tube 530, ensuring the continuity and stability of the fertilizer transmission process and avoiding the risk of breakage or blockage due to the rigid connection of the pipeline.

[0055] In one embodiment, see Figure 6 The metering unit 400 includes a hopper 410 fixed on the stand 300, and a turning frame 420 is rotatably mounted on one side of the hopper 410. The turning frame 420 is provided with a first arc-shaped sealing plate 430 adapted to the bottom opening of the hopper 410 and a second arc-shaped sealing plate 440 adapted to the top opening of the hopper 410. A weighing and measuring part is provided on the first arc-shaped sealing plate 430, and an arc-shaped chute 450 adapted to the second arc-shaped sealing plate 440 is opened on the inner wall of the hopper 410;

[0056] Specifically, in the initial state, the second arc-shaped sealing plate 440 blocks the bottom opening of the hopper 410, while the second arc-shaped sealing plate 440 and the top opening of the hopper 410 are staggered with each other, and at this time, the top opening of the hopper 410 is in an open state; the organic fertilizer is poured into the hopper 410, and the organic fertilizer in the hopper 410 is dynamically measured by the weighing and measuring parts on the first arc-shaped sealing plate 430. When the weight of the organic fertilizer reaches the set value, the turning frame 420 turns upward, thereby causing the second arc-shaped sealing plate 440 to turn into the arc-shaped chute 450 to block the top opening of the hopper 410, completing the quantitative distribution of the organic fertilizer under this batch; at the same time, the first arc-shaped sealing plate 430 turns out from the bottom opening of the hopper 410, and the bottom opening of the hopper 410 is connected, so that the organic fertilizer measured in this batch in the hopper 410 can be discharged into the inner rigid tube 510 below;

[0057] When the organic fertilizer of this batch is emptied, the turning frame 420 turns over and resets again, so that the first arc-shaped sealing plate 430 blocks the bottom opening of the hopper 410. At the same time, the first arc-shaped sealing plate 430 is rotated out from the top opening of the hopper 410, and the top opening of the hopper 410 is opened again, and the external organic fertilizer continues to be discharged into the hopper 410 for the next batch of fertilizer measurement and distribution; this reciprocating process can achieve accurate batch measurement of organic fertilizers, while improving the orderliness of fertilizer packaging and avoiding blockage caused by continuous filling.

[0058] It is worth noting that the weighing and measuring element provided on the first arc-shaped closing plate 430 can perform dynamic measurement when the organic fertilizer is poured into the hopper 410. This dynamic measurement method can monitor the weight of the fertilizer in real time, ensuring that the weight of the fertilizer loaded each time reaches the set value, thereby achieving high-precision quantitative distribution;

[0059] By the flipping action of the flipping frame 420, the top and bottom openings of the hopper 410 are alternately blocked and opened; when the weight of the fertilizer reaches the set value, the flipping frame 420 flips upward, so that the second arc-shaped sealing plate 440 blocks the top opening of the hopper 410, and at the same time the first arc-shaped sealing plate 430 flips out from the bottom opening, allowing the batch of fertilizer to be discharged into the inner rigid tube 510. This process ensures the accurate measurement of each batch of fertilizer and avoids weight errors and blockage problems that may be caused by continuous filling; when a batch of fertilizer is emptied, the flipping frame 420 is reset, the first arc-shaped sealing plate 430 re-blocks the bottom opening, the top opening is opened again, and the external fertilizer continues to be discharged into the hopper 410 for the next batch of metering and distribution. This alternating action ensures the continuous supply and batch filling of fertilizer, thereby improving production efficiency.

[0060] In addition, the batch loading method avoids the blockage problem that may be caused by continuous loading. By precisely controlling the weight and loading order of each batch of fertilizer, it ensures the smoothness of the fertilizer during transportation and loading, reducing production interruptions and equipment maintenance costs caused by blockage.

[0061] Further, see Figure 7 The weighing and measuring member includes a bottom plate 431 provided on the first arc-shaped sealing plate 430, a measuring sensor 433 is installed in the bottom plate 431, and a measuring plate 432 is provided on the upper end surface of the measuring sensor 433;

[0062] Specifically, when the organic fertilizer enters the hopper 410 , the weight of the organic fertilizer is applied to the metering plate 432 , and the metering sensor 433 is used to weigh the organic fertilizer above the metering plate 432 , so as to achieve batch measurement and distribution of the organic fertilizer in the hopper 410 .

[0063] The above-mentioned measuring sensor 433 can use an S-type weighing sensor, specifically model WS40, with a measuring range of 10-50kg, an output sensitivity of 2.0±0.25%mV / N, an accuracy of 0.018%FS nonlinearity, a hysteresis of ±0.018%FS, a repeatability of 0.018%FS, and a response time of ≤50ms.

[0064] Furthermore, considering that after the second arc-shaped sealing plate 440 is rotated out of the arc-shaped chute 450, a small amount of organic fertilizer will inevitably enter the arc-shaped chute 450, and this part of the fertilizer will hinder the second arc-shaped sealing plate 440 from entering the arc-shaped chute 450 again. Figure 8 , wedge blocks 441 adapted to the corresponding arc-shaped chute 450 are provided at both ends of the second arc-shaped sealing plate 440;

[0065] When the second arc-shaped sealing plate 440 flips toward the arc-shaped chute 450, the wedge block 441 will scrape the fertilizer in the arc-shaped chute 450, so that the fertilizer along the arc-shaped chute 450 is discharged, allowing the second arc-shaped sealing plate 440 to smoothly enter the arc-shaped chute 450 again.

[0066] See also Figure 9 In order to realize the reciprocating turning of the turning frame 420, a rotating shaft 460 is rotatably mounted on one side of the hopper 410. The turning frame 420 is fixedly sleeved on the rotating shaft 460. One end of the rotating shaft 460 is fixedly connected to a connecting rod 470. A turning cylinder 480 is rotatably connected to the outer wall of the hopper 410. The protruding end of the turning cylinder 480 is hinged to the connecting rod 470.

[0067] Specifically, the telescopic movement of the flip cylinder 480 can drive the connecting rod 470 to swing circumferentially, thereby driving the rotating shaft 460 to rotate, thereby realizing the flipping action of the rotating shaft 460.

[0068] In yet another embodiment, see Figure 5 In order to improve the dredging effect of fertilizer, a ring sleeve 540 is fixed to the inner wall of the outer rigid tube 530, and a swivel 550 is rotatably embedded in the ring sleeve 540. A central column 560 is provided at the center of the swivel 550, and a plurality of blades 570 are circumferentially arranged between the central column 560 and the swivel 550; a rotating rod 580 is coaxially fixed to the central column 560, and a first spiral piece 590 is provided on the rotating rod 580. A second spiral piece 730 adapted to the first spiral piece 590 is provided on the inner wall of the air pipe 720;

[0069] Specifically, when the outer rigid tube 530 follows the lifting frame 620 to move back and forth, the rotating rod 580 at the upper end of the central column 560 is periodically inserted into the air pipe 720; when the outer rigid tube 530 moves upward, the rotating rod 580 is vertically inserted into the air pipe 720, and the first spiral piece 590 is threadedly connected with the second spiral piece 730, so that the rotating rod 580 is lifted and rotated spirally relative to the air pipe 720, thereby driving the rotating ring 550 and the blade 570 to rotate circumferentially relative to the ring sleeve 540, and the circumferentially rotating blade 570 is used to further guide the fertilizer falling in the outer rigid tube 530 to prevent the fertilizer from accumulating and clogging in the outer rigid tube 530; in addition, when the rotating rod 580 is spirally rotated in the air pipe 720, a spiral airway is formed between the first spiral piece 590 and the second spiral piece 730, and the airflow in the air pipe 720 is spirally ejected through the spiral airway, which can increase the contact range between the airflow and the fertilizer, thereby improving the pneumatic dredging effect.

[0070] It is worth noting that when the outer rigid tube 530 follows the lifting frame 620 to move back and forth, the rotating rod 580 is periodically inserted into the air pipe 720; during the rising process, the first spiral piece 590 is threadedly connected with the second spiral piece 730 in the air pipe 720, so that the rotating rod 580 rotates spirally relative to the air pipe 720 while rising, thereby driving the rotating ring 550 and the blade 570 to rotate circumferentially. The circumferential rotation of the blade 570 can continuously stir and guide the falling fertilizer, effectively preventing the fertilizer from being trapped in the outer rigid tube 530. 0 accumulation and blockage; when the rotating rod 580 spirally rotates in the air pipe 720, a spiral airway is formed between the first spiral piece 590 and the second spiral piece 730, and the airflow in the air pipe 720 is spirally ejected through the spiral airway, which increases the contact range between the airflow and the fertilizer and further improves the pneumatic dredging effect. The design of the spiral airway enables the airflow to act on the fertilizer more evenly, further improving the dredging effect; the dredging method with the coordinated action of mechanical and pneumatic forces can more comprehensively prevent fertilizer blockage and ensure that the fertilizer falls smoothly.

[0071] It should be noted that in this embodiment, in order to ensure that the rotating rod 580 can be driven smoothly and realize circumferential rotation, the helical angle of the first helical plate 590 and the second helical plate 730 should be greater than the friction angle, that is, there is no self-locking property between the first helical plate 590 and the second helical plate 730.

[0072] Further, see Figure 5 In order to allow the gas ejected from the air pipe 720 to be discharged smoothly, a plurality of inclined exhaust pipes 531 are provided on the circumference of the outer rigid tube 530, and a filter 532 is provided at one end of the exhaust pipe 531 that is inclined upward;

[0073] Specifically, when the gas in the air pipe 720 is ejected to pneumatically guide the fertilizer in the outer rigid tube 530, the ejected gas can be smoothly discharged through the exhaust pipe 531 on the outer rigid tube 530, thereby ensuring the stability of the internal air pressure of the outer rigid tube 530. The inclined exhaust pipe 531 can reduce the interference of the gas on the falling fertilizer during discharge. The filter 532 set on the exhaust pipe 531 can further isolate and intercept the fertilizer, effectively preventing the falling fertilizer from overflowing.

[0074] In further embodiments, see Figure 4 、 Figure 10 and Figure 11 The barrel mouth connector 630 includes two sets of connecting blocks 631 symmetrically fixed on the outer wall of the outer rigid tube 530. The two sets of connecting blocks 631 are rotatably mounted with a swing frame 632. The lower end of the swing frame 632 is fixed with a semi-annular clamp 633 through a pressing block 634. A first clamping cylinder 635 is hinged between the two sides of the swing frame 632.

[0075] Specifically, when the lifting cylinder 610 drives the lifting frame 620 downward until the semi-annular clamp 633 is at the same height as the annular recess 130 of the barrel mouth 120, the first clamping cylinder 635 contracts, thereby driving the swing frames 632 on both sides to flip toward the middle until the semi-annular clamp 633 is stuck in the annular recess 130. The semi-annular clamp 633 tightened on both sides can be used to clamp and fix the barrel mouth 120 and the outer rigid tube 530 to prevent the barrel mouth 120 and the outer rigid tube 530 from accidentally falling off during the fertilizer filling process.

[0076] It should be noted that when the lifting cylinder 610 drives the lifting frame 620 downward, making the semi-annular clamp 633 and the annular recess 130 of the barrel mouth 120 at the same height, the first clamping cylinder 635 contracts, driving the swing frames 632 on both sides to flip toward the middle until the semi-annular clamp 633 is stuck in the annular recess 130. This design uses the semi-annular clamp 633 tightened on both sides to clamp the barrel mouth 120 and the outer rigid tube 530, effectively preventing the barrel mouth 120 and the outer rigid tube 530 from accidentally falling off during the fertilizer filling process, not only ensuring the sealing between the barrel mouth 120 and the outer rigid tube 530, but also improving the stability of the filling process, avoiding fertilizer leakage and uneven filling due to loose barrel mouth 120.

[0077] Further, see Figure 4 、 Figure 10 and Figure 12 The lifting belt connecting member 640 includes a mounting plate 641 fixed to the lifting frame 620, a sleeve shaft 642 fixed to the mounting plate 641, a rocker arm 643 rotatably mounted on the sleeve shaft 642, a support rod 644 fixed to the lower end of the rocker arm 643, a second clamping cylinder 645 rotatably mounted on the mounting plate 641, the extended end of the second clamping cylinder 645 is hinged to the upper end of the rocker arm 643, and a flexible baffle 646 adapted to the support rod 644 is fixed to the mounting plate 641;

[0078] Specifically, before loading the fertilizer, each lifting strap 140 on the packaging barrel 100 is passed through the connection gap between the flexible baffle 646 and the support rod 644 and is inserted above the support rod 644 to connect the lifting strap 140 to the lifting strap connector 640. The flexible baffle 646 can block the lifting strap 140, thereby preventing the lifting strap 140 from falling off from the lifting strap connector 640 during the reciprocating lifting of the packaging barrel 100.

[0079] When the fertilizer is loaded, the extended end of the second clamping cylinder 645 retracts, driving the rocker arm 643 to flip upward around the sleeve shaft 642, so that the support rod 644 and the flexible baffle 646 are separated, and the lifting belt 140 can be removed from the support rod 644.

[0080] It should be noted that before filling the fertilizer, each lifting strap 140 on the packaging barrel 100 is passed through the connection gap between the flexible baffle 646 and the support rod 644 and is clamped above the support rod 644. The flexible baffle 646 can block the lifting strap 140 to prevent the lifting strap 140 from falling off from the lifting strap connector 640 during the reciprocating lifting of the packaging barrel 100, thereby ensuring the stability and reliability of the lifting strap 140 during the filling process and preventing the lifting strap 140 from loosening during the reciprocating motion, thereby ensuring the stable lifting and compaction of the packaging barrel 100.

[0081] When the fertilizer is loaded, the extended end of the second clamping cylinder 645 retracts, driving the rocker arm 643 to flip upward around the sleeve shaft 642, so that the support rod 644 and the flexible baffle 646 are separated, and the lifting belt 140 can be removed from the support rod 644, making the release process of the lifting belt 140 simple and quick, improving production efficiency and reducing manual intervention.

The above specific embodiments are merely illustrative and not restrictive. Under the guidance of the present invention, those skilled in the art can also make many forms, all of which are protected by the present invention.
