Description

Technical Field

[0001] The present invention relates to the technical field of packaging, and more specifically, it relates to a metering and packing device for organic fertilizer production. Background Art

[0002] With the development of organic agriculture, organic fertilizers are widely used due to their environmental protection characteristics; however, organic fertilizers generally have physical characteristics such as high viscosity, high humidity, and easy caking, and are extremely prone to adhesion and accumulation on the inner wall of the conveying pipeline during the packaging process, resulting in frequent blockage problems of traditional continuous filling equipment; In the prior art, most packing devices adopt a straight - drop continuous filling mode, where organic fertilizers freely fall under the action of gravity, lacking a dynamic dredging mechanism. Viscous materials are prone to form an arching effect at the pipe diameter change, causing the flow channel to be blocked; especially when the equipment operates for a long time, the residual fertilizers on the inner wall of the pipeline gradually harden, further increasing the risk of blockage, and frequent shutdowns for cleaning are required, seriously affecting production efficiency; In addition, traditional devices lack a densification treatment link. Loose fertilizers are unevenly stacked in the barrel, and the void ratio is high 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 - mentioned defects have restricted the efficiency and quality stability of large - scale production of organic fertilizers to a certain extent. Summary of the Invention

[0003] In order to overcome the above - mentioned technical problems, the present invention proposes a metering and packing device for organic fertilizer production.

[0006] As a further solution of the present invention: The weighing and metering component includes a bottom plate arranged on the first arc-shaped sealing plate. A metering inductor is installed inside the bottom plate, and a metering plate is arranged at the upper end of the metering inductor.

[0007] As a further solution of the present invention: Wedge-shaped blocks adapted to the corresponding arc-shaped sliding grooves are arranged at both ends of the second arc-shaped sealing plate.

[0008] As a further solution of the present invention: A rotating shaft is rotatably installed on one side of the hopper. The turnover frame is fixedly sleeved on the rotating shaft. One end of the rotating shaft is fixedly connected with a connecting rod.

[0010] As a further solution of the present invention: A rotating rod is coaxially fixed on the central column. A first spiral piece is arranged on the rotating rod, and a second spiral piece adapted to the first spiral piece is arranged on the inner wall of the air pipe.

[0011] As a further solution of the present invention: A plurality of inclined exhaust pipes are circumferentially arranged on the outer rigid tube. A filter screen is arranged at the upwardly inclined end of the exhaust pipe.

[0012] As a further solution of the present invention: The barrel mouth connecting piece includes two groups of connecting blocks symmetrically fixed on the outer wall of the outer rigid tube.

[0018] Now, the subject matter described herein will be discussed with reference to exemplary embodiments. It should be understood that discussing these embodiments is only to enable those skilled in the art to better understand and thus implement the subject matter described herein.

[0019] Please refer to Figure 1 , the present invention discloses a metering and packing device for organic fertilizer production, which is used to meter and fill organic fertilizer into the 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 recess 130 is provided outside the barrel mouth 120, and a plurality of lifting belts 140 are circumferentially provided outside the barrel body 110 Please refer to Figure 2 , Figure 3 and Figure 4, the metering and packing device includes a packing table 200 for placing the packing barrel 100 and a gantry 300 located directly above the packing table 200, and further 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 gantry 300 and is used for metering 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, and includes an inner rigid pipe 510 fixed on the gantry 300 and a threaded flexible pipe 520 fixedly sleeved outside the inner rigid pipe 510. The lower end of the threaded flexible pipe 520 is connected to an outer rigid pipe 530 adapted to the barrel mouth 120; the clamping unit 600 is arranged on the gantry 300 and includes a lifting cylinder 610 fixed on the gantry 300 and a lifting frame 620 connected to the output end of the lifting cylinder 610. The outer rigid pipe 530 is fixed at the center of the lifting frame 620. A barrel mouth connecting piece 630 adapted to the annular recess 130 is also arranged at the center of the lifting frame 620. A plurality of lifting belt connecting pieces 640 adapted to the corresponding lifting belts 140 are arranged on the outer circumference of the lifting frame 620 in a circumferential direction; the dredging unit 700 includes a blower 710 fixed on the gantry 300 and an air pipe 720 connected to the output end of the blower 710. The air pipe 720 penetrates and vertically extends into the inner rigid pipe 510; Specifically, place the empty packing barrel 100 on the packing table 200, and make the barrel mouth 120 of the packing barrel 100 located directly below the outer rigid pipe 530. Drive the lifting frame 620 to descend through the lifting cylinder 610 until the outer rigid pipe 530 is inserted into the barrel mouth 120. At the same time, the barrel mouth connecting piece 630 reaches the same height as the annular recess 130. Through the adaptation of the barrel mouth connecting piece 630 and the annular recess 130, the barrel mouth 120 is hermetically connected to the outer rigid pipe 530. Then connect each lifting belt 140 to the corresponding lifting belt connecting piece 640, and the clamping and fixing of the packing barrel 100 and the clamping unit 600 can be realized; The organic fertilizer is quantitatively weighed in multiple batches by the metering unit 400. The metered fertilizer enters the barrel body 110 in batches through the inner rigid pipe 510 and the outer rigid pipe 530. During the falling process of the fertilizer, the lifting frame 620 reciprocates up and down by the reciprocating telescoping of the lifting cylinder 610, so that each group of lifting belt connecting pieces 640 periodically pulls up the lifting belt 140 upwards, and the bottom of the packing barrel 100 periodically impacts the packing 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; During the process of batch loading of organic fertilizers, the blower 710 is turned on, and air is blown into the inner rigid pipe 510 through the blower 710. During the reciprocating lifting of the lifting frame 620, the outer rigid pipe 530 also makes a periodic lifting motion relative to the inner rigid pipe 510, and the threaded flexible pipe 520 adaptively expands and contracts. When the outer rigid pipe 530 makes a periodic lifting motion, relative motion also occurs between the outer rigid pipe 530 and the air pipe 720 in the inner rigid pipe 510. Thus, the air flow ejected from the air pipe 720 is used to blow and guide the fertilizers in the outer rigid pipe 530, preventing the accumulation and blockage of organic fertilizers in the outer rigid pipe 530 and improving the smoothness of fertilizer loading.

[0020] It should be noted that during the process of batch loading of organic fertilizers, the reciprocating telescoping of the lifting cylinder 610 drives the reciprocating lifting of the lifting frame 620. The lifting belt 140 is periodically pulled upward through the lifting belt connecting member 640, causing the bottom of the packaging barrel 100 to periodically impact the packing table 200. Thereby, the fertilizers entering the barrel body 110 in batches can be compacted, effectively improving the packing density of the organic fertilizers in the barrel body 110, reducing the voids of the fertilizers in the packaging barrel 100, increasing the utilization rate of the packaging space, and at the same time avoiding the risks of packaging deformation and rupture caused by loose fertilizers. During the fertilizer loading process, the blower 710 blows air into the inner rigid pipe 510 through the air pipe 720, and the air flow is used to blow and guide the fertilizers in the outer rigid pipe 530. When the outer rigid pipe 530 makes a periodic lifting motion, relative motion occurs between the air pipe 720 and the outer rigid pipe 530, further enhancing the air flow guiding effect, effectively preventing the accumulation and blockage of organic fertilizers in the outer rigid pipe 530, ensuring the smoothness of fertilizer loading, and improving the loading efficiency. By driving the lifting frame 620 to descend through the lifting cylinder 610, precise docking between the outer rigid pipe 530 and the barrel mouth 120 of the packaging barrel 100 is achieved. Through the adaptation of the barrel mouth connecting member 630 and the annular recessed portion 130, the barrel mouth 120 and the outer rigid pipe 530 are hermetically connected, ensuring that the fertilizers will not leak during the loading process. At the same time, through the connection between the lifting belt connecting member 640 and the lifting belt 140, firm clamping between the packaging barrel 100 and the clamping unit 600 is realized, ensuring the stability and reliability of the entire loading process and preventing the packaging barrel 100 from shifting or toppling during the loading process. The metering unit 400 can conduct multi-batch quantitative weighing of organic fertilizers, ensuring that the weight of the fertilizers loaded each time is accurate and consistent, effectively improving the precision of fertilizer packaging, avoiding problems such as fertilizer waste and non-compliance of packaging weight, and enhancing the stability of product quality. 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, thereby 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.

[0021] In one embodiment, see Figure 6 The metering unit 400 includes a hopper 410 fixed on the stand 300, a flip frame 420 is rotatably mounted on one side of the hopper 410, 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 are provided on the flip frame 420, a weighing and measuring piece is provided on the first arc-shaped sealing plate 430, and an arc-shaped slide groove 450 adapted to the second arc-shaped sealing plate 440 is provided on the inner wall of the hopper 410; Specifically, in the initial state, the second arc-shaped sealing plate 440 blocks the bottom opening of the hopper 410, and 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, so that the second arc-shaped sealing plate 440 is transferred into the arc-shaped slide 450 to block the top opening of the hopper 410, and the quantitative distribution of the organic fertilizer under this batch is completed; at the same time, the first arc-shaped sealing plate 430 is turned 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; When the batch of organic fertilizer is emptied, the flip frame 420 flips 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 to measure and distribute the next batch of fertilizer; 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.

[0022] It is worth noting that the weighing and measuring element provided on the first arc-shaped sealing 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 to ensure that the weight of the fertilizer filled each time reaches the set value, thereby achieving high-precision quantitative distribution; Through the flipping action of the flipping frame 420, the alternate blocking and conducting of the top and bottom openings of the hopper 410 are achieved; when the weight of the fertilizer reaches the set value, the flipping frame 420 flips upward, causing the second arc-shaped sealing plate 440 to block the top opening of the hopper 410. At the same time, the first arc-shaped sealing plate 430 flips out from the bottom opening, allowing this batch of fertilizer to be discharged into the inner rigid pipe 510. This process ensures the accurate metering 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 resets, the first arc-shaped sealing plate 430 re-blocks the bottom opening, and the top opening is conducted again. External fertilizer continues to be discharged into the hopper 410 for the metering and distribution of the next batch. This alternating action ensures the continuous supply and batch filling of fertilizer, improving production efficiency.

[0023] In addition, the batch filling method avoids the blockage problems that may be caused by continuous filling. By precisely controlling the weight and filling sequence of each batch of fertilizer, the smoothness of the fertilizer during transmission and filling is ensured, reducing production interruptions and equipment maintenance costs caused by blockages.

[0024] Furthermore, please refer to Figure 7 , the weighing and metering component includes a bottom plate 431 provided on the first arc-shaped sealing plate 430. A metering sensor 433 is installed inside the bottom plate 431, and a metering plate 432 is provided on the upper end surface of the metering sensor 433; Specifically, when the organic fertilizer enters the hopper 410, the weight of the organic fertilizer is applied to the metering plate 432, so as to use the metering sensor 433 to measure and weigh the organic fertilizer above the metering plate 432, so as to achieve the batch metering and distribution of the organic fertilizer in the hopper 410.

[0025] The above metering sensor 433 can use an S-type load cell, with the specific model WS40, range: 10 - 50 kg, output sensitivity: 2.0 ± 0.25% mV / N, accuracy: non-linearity 0.018% F.S., hysteresis ± 0.018% F.S., repeatability 0.018% F.S., response time: ≤ 50 ms.

[0026] Even further, considering that after the second arc-shaped sealing plate 440 turns out from 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. For this reason, please refer to Figure 8 , wedge-shaped blocks 441 adapted to the corresponding arc-shaped chutes 450 are provided at both ends of the second arc-shaped sealing plate 440; When the second arc-shaped sealing plate 440 flips into the arc-shaped chute 450, the wedge-shaped block 441 scrapes the fertilizer in the arc-shaped chute 450, so that the fertilizer along the arc-shaped chute 450 is discharged, enabling the second arc-shaped sealing plate 440 to smoothly enter the arc-shaped chute 450 again.

[0027] Please refer to Figure 9 , in order to achieve the reciprocating flipping of the flipping frame 420, a rotating shaft 460 is rotatably installed on one side of the hopper 410. The flipping 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 flipping cylinder 480 is rotatably connected to the outer wall of the hopper 410. The extending end of the flipping cylinder 480 is hinged to the connecting rod 470; Specifically, through the telescopic movement of the flipping cylinder 480, the connecting rod 470 can be driven to swing circumferentially, and then the rotating shaft 460 is driven to rotate, so as to achieve the flipping action of the rotating shaft 460.

[0028] In another embodiment, please refer to Figure 5 , in order to improve the dredging effect on the fertilizer, a ring sleeve 540 is fixed to the inner wall of the outer rigid tube 530. A rotating ring 550 is rotatably embedded in the ring sleeve 540. A central column 560 is arranged at the center of the rotating ring 550. A plurality of blades 570 are circumferentially arranged between the central column 560 and the rotating ring 550; A rotating rod 580 is coaxially fixed on the central column 560. A first spiral blade 590 is arranged on the rotating rod 580. A second spiral blade 730 adapted to the first spiral blade 590 is arranged on the inner wall of the air pipe 720; Specifically, when the outer rigid tube 530 reciprocates up and down with the lifting frame 620, the rotating rod 580 at the upper end of the central column 560 periodically inserts into the air pipe 720; when the outer rigid tube 530 moves upward, the rotating rod 580 vertically inserts into the air pipe 720, and the first spiral blade 590 is threadedly connected to the second spiral blade 730, so that while the rotating rod 580 rises, it rotates spirally relative to the air pipe 720, thereby driving the rotating ring 550 and the blades 570 to rotate circumferentially relative to the ring sleeve 540, and further dredging the fertilizer falling in the outer rigid tube 530 by using the circumferentially rotating blades 570 to prevent the fertilizer from accumulating and blocking in the outer rigid tube 530; in addition, when the rotating rod 580 rotates spirally in the air pipe 720, a spiral air passage is formed between the first spiral blade 590 and the second spiral blade 730, and the air flow in the air pipe 720 is sprayed out spirally through the spiral air passage, which can increase the contact range between the air flow and the fertilizer, and further improve the pneumatic dredging effect.

[0029] 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 avoiding the fertilizer from being trapped in the outer rigid tube 530. 0; 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, thereby increasing the contact range between the airflow and the fertilizer, further improving 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 of the coordinated action of mechanical and pneumatic forces can more comprehensively prevent fertilizer blockage and ensure the smooth fall of the fertilizer.

[0030] 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 helix 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.

[0031] For further information, 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 arranged on the circumference of the outer rigid pipe 530, and a filter screen 532 is arranged at one end of the exhaust pipe 531 that is inclined upward; Specifically, when the gas in the air pipe 720 is sprayed out to pneumatically guide the fertilizer in the outer rigid tube 530, the sprayed 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 arranged on the exhaust pipe 531 can further isolate and intercept the fertilizer, effectively preventing the falling fertilizer from overflowing.

[0032] In further embodiments, see Figure 4 , Figure 10 and Figure 11 The barrel mouth connection member 630 includes two groups of connection blocks 631 symmetrically fixed on the outer wall of the outer rigid tube 530, and swing frames 632 are rotatably mounted on the two groups of connection blocks 631. The lower end of the swing frame 632 is fixed with a semi-annular clamp 633 through a pressing block 634, and a first clamping cylinder 635 is hinged between the swing frames 632 on both sides; Specifically, when the lifting cylinder 610 drives the lifting frame 620 to descend until the semi-circular clamp 633 is at the same height as the annular recess 130 of the barrel opening 120, the first clamping cylinder 635 contracts, driving the swing frames 632 on both sides to flip and approach each other until the semi-circular clamp 633 is snapped into the annular recess 130. In this way, the semi-circular clamps 633 tightened on both sides can clamp and fix the barrel opening 120 and the outer rigid pipe 530, preventing accidental detachment between the barrel opening 120 and the outer rigid pipe 530 during the fertilizer loading process.

[0033] It should be noted that when the lifting cylinder 610 drives the lifting frame 620 to descend so that the semi-circular clamp 633 is at the same height as the annular recess 130 of the barrel opening 120, the first clamping cylinder 635 contracts, driving the swing frames 632 on both sides to flip and approach each other until the semi-circular clamp 633 is snapped into the annular recess 130. This design uses the semi-circular clamps 633 tightened on both sides to clamp and fix the barrel opening 120 and the outer rigid pipe 530, effectively preventing accidental detachment between the barrel opening 120 and the outer rigid pipe 530 during the fertilizer loading process. It not only ensures the sealing between the barrel opening 120 and the outer rigid pipe 530 but also improves the stability of the loading process, avoiding fertilizer leakage and uneven loading caused by loosening of the barrel opening 120.

[0034] Further, please refer to 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 is fixed on the mounting plate 641. A swing rod 643 is rotatably mounted on the sleeve shaft 642. A support rod 644 is fixed to the lower end of the swing rod 643. A second clamping cylinder 645 is also rotatably mounted on the mounting plate 641. The extending end of the second clamping cylinder 645 is hinged to the upper end of the swing rod 643. A flexible stop 646 adapted to the support rod 644 is fixed on the mounting plate 641. Specifically, before loading the fertilizer, each lifting belt 140 on the packaging barrel 100 is passed through the connection gap between the flexible stop 646 and the support rod 644 and snapped above the support rod 644 to achieve the connection between the lifting belt 140 and the lifting belt connecting member 640. The flexible stop 646 can block the lifting belt 140, preventing the lifting belt 140 from detaching from the lifting belt connecting member 640 during the process of repeatedly lifting the packaging barrel 100. When the fertilizer loading is completed, the extending end of the second clamping cylinder 645 retracts, driving the swing rod 643 to flip upward around the sleeve shaft 642, enabling the support rod 644 to separate from the flexible stop 646, and the lifting belt 140 can then be removed from the support rod 644.

[0035] It should be noted that before filling the fertilizer, each lifting belt 140 on the packaging barrel 100 is passed through the connection gap between the flexible baffle 646 and the support rod 644 and snapped above the support rod 644. The flexible baffle 646 can block the lifting belt 140, preventing the lifting belt 140 from detaching from the lifting belt connector 640 during the process of reciprocatingly lifting the packaging barrel 100, ensuring the stability and reliability of the lifting belt 140 during the filling process, avoiding the loosening of the lifting belt 140 during reciprocating motion, and thus guaranteeing the stable lifting and ramming treatment of the packaging barrel 100; When the fertilizer filling is completed, the extending end of the second clamping cylinder 645 retracts, driving the swing rod 643 to turn upward around the sleeve shaft 642, separating the support rod 644 from the flexible baffle 646, and the lifting belt 140 can be removed from the support rod 644, making the release process of the lifting belt 140 simple and fast, improving the production efficiency and reducing manual intervention.
