Description

Technical Field

[0001] The invention relates to the technical field of equipment for processing bio-organic fertilizer, in particular to bio-organic fertilizer granulation equipment and a granulation method thereof. Background Art

[0002] During the processing of bio-organic fertilizers, granulation equipment is often required to granulate and shape the bio-organic fertilizer. Currently, the main equipment used for granulation of bio-organic fertilizers is disc granulators and screw extruder granulators. Due to the poor adaptability of traditional disc granulators to high-humidity materials and the relatively loose nature of bio-organic fertilizers, screw extruder granulators are currently the most commonly used granulation equipment.

[0003] Most existing screw extruders for bio-organic fertilizer granulation use conventional screw extruders, which generally include a fixed housing with a guide hole and a feed screw that rotates within the guide hole of the fixed housing. Driven by an external drive mechanism, the feed screw rotates to extrude the material entering the guide hole of the fixed housing, causing the material to pass through the corresponding forming die holes and be extruded into granules. Although the forming efficiency is relatively high, the particle size of the material varies greatly, resulting in relatively insufficient granulation uniformity. In addition, the material is significantly torn when it is disconnected, causing the ends of the granular material to become loose and fragmented, resulting in a high breakage rate of the formed material.

[0004] Therefore, under the premise of not affecting the granulation efficiency of the material, designing a biological organic fertilizer granulation equipment and a granulation method thereof that can effectively ensure the granulation uniformity of the material and can effectively and significantly reduce the breakage rate of the material after granulation is the research purpose of the present invention. Summary of the Invention

[0005] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a bio-organic fertilizer granulation equipment and a granulation method thereof, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is: A bio-organic fertilizer granulation device, comprising: A fixed casing, wherein at least one corresponding guide hole is provided in the fixed casing, a lower hopper connected to the guide hole is provided on the upper side of the fixed casing, an extrusion screw is rotatably installed at the guide hole, and the extrusion screw is driven by a corresponding driving mechanism, and an end cover plate with a plurality of discharge guide holes provided on the periphery is fixedly installed at the end of the fixed casing; A forming assembly comprising a forming cover plate rotatably mounted on the outer side of the end cover plate, the forming cover plate being driven by a corresponding swing drive mechanism, the outer end surface of the end cover plate being provided with a first forming groove connected to the discharge guide hole, and the inner end surface of the forming cover plate being provided with a second forming groove adapted to the first forming groove; A multifunctional cutting assembly includes a spring sheet movably plugged into an end cover plate on the upper side of the first forming groove, wherein the inner ends of the spring sheets extend through and to the junction of the discharge guide hole and the first forming groove, and the outer ends of the spring sheets are respectively fixedly connected to corresponding magnetic metal plates, and the magnetic metal plates are respectively fixedly mounted to the outer side of the end cover plate via corresponding elastic members; The cutting drive mechanism comprises a plurality of magnets fixedly embedded on the forming cover plate, and the magnets are respectively facing the magnetic metal plates.

[0007] When the forming cover plate swings downward until it abuts against the outer end surface of the end cover plate, the magnet parts respectively drive the corresponding magnetic metal plates to attract each other, the elastic part is compressed, and the spring sheet leaves the connection between the discharge guide hole and the first forming groove; when the forming cover plate swings upward until it leaves the end cover plate, the elastic part recovers its deformation and drives the spring sheet to return to the connection between the discharge guide hole and the first forming groove, so as to cut the formed spherical material.

[0008] The first molding groove and the second molding groove are spherical grooves respectively. When the molding cover plate swings downward to fit and abut against the outer end surface of the end cover plate, the first molding groove and the second molding groove are combined into an integral spherical molding cavity.

[0009] After the elastic member recovers its deformation to drive the spring sheet to cut the formed spherical material, the subsequently extruded material drives the end of the spring sheet forward, and the end of the spring sheet swings forward to push the formed spherical material away from the first forming groove for blanking.

[0010] Corresponding limiting grooves are respectively recessed on the forming cover plate on the inner side of the second forming groove, and arc panels extending into the second forming groove are fixedly installed outwardly in the limiting grooves through corresponding buffer rubber parts. After the material is squeezed and fills the spherical forming cavity formed by the second forming groove and the first forming groove, the buffer rubber parts are squeezed until the arc panels are located in the corresponding limiting grooves.

[0011] When the forming cover plate swings upward to leave the end cover plate, the buffer rubber member returns to its original position to form an outward driving force on the arc plate, so as to push the formed material to leave the second forming groove.

[0012] The driving mechanism includes a driving motor and a reducer connected to the output shaft end of the driving motor, and the extrusion screw is connected to the output shaft end of the reducer; the swing driving mechanism adopts a group of driving cylinders.

[0013] The extrusion end of the extrusion screw can be rotatably mounted on the center of the end cover plate.

[0014] The elastic member is a magnetic metal coil spring, and the magnetic metal coil spring is fixedly installed on the outer side of the end cover plate through a corresponding connecting plate.

[0015] A bio-organic fertilizer granulation method, based on the above-mentioned bio-organic fertilizer granulation equipment, comprises the following specific steps: S1, the organic fertilizer material enters the guide hole of the fixed housing through the lower hopper, and the extrusion screw rotates to transport the organic fertilizer material and press it into the discharge guide hole of the end cover in an extruded state; S2, the forming cover plate swings downward until it abuts against the outer end surface of the end cover plate, the magnet member attracts and drives the corresponding magnetic metal plate, and the spring sheet leaves the connection between the discharge guide hole and the first forming groove; S3, the organic fertilizer material is squeezed into the first forming trough and the second forming trough to form granular material; S4, the forming cover plate swings upward to leave the end cover plate, and the elastic member recovers its deformation to drive the spring sheet to return to the junction of the discharge guide hole and the first forming groove to cut the formed spherical material; S5, the cut granular material rolls down through the first forming trough for output.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are: 1) Based on an end cover plate with multiple discharge guide holes at its periphery, the present invention further includes a forming assembly, a multifunctional cutting assembly, and a cutting drive mechanism. The cutting drive mechanism includes a plurality of magnets fixedly mounted on the forming cover plate of the forming assembly, so that the forming and discharge of the material, as well as the drive control of the cutting drive mechanism, can be synchronously adapted to the forming and discharge of the material, and the driving control of the cutting drive mechanism can be achieved by flipping the forming cover plate. During the forming process, the forming cover plate swings downward until it abuts against the outer end surface of the end cover plate, forming a corresponding forming space between the first forming groove and the second forming groove. At this time, the magnets respectively attract and drive the corresponding magnetic metal plates, causing the corresponding spring pieces to leave the connection between the discharge guide holes and the first forming groove to facilitate the extrusion and discharge of the material. As the material continues to be extruded and discharged, it can effectively fill the space between the first forming groove and the second forming groove for sufficient granulation and forming. After granulation and forming, the forming cover plate swings upward to leave the end cover plate, and the elastic member recovers its deformation to drive the corresponding spring piece to return it to the connection between the discharge guide hole and the first forming groove to cut the formed spherical material.

[0017] In this way, it is possible to form a reasonable granulation process for the material and effectively ensure the granulation uniformity of the material, and it is also possible to effectively and significantly reduce the breakage rate of the material after granulation.

[0018] 2) After the elastic member of the present invention recovers its deformation to drive the corresponding spring leaf to cut the formed spherical material, the subsequently extruded material will drive the end of the spring leaf forward. At this time, the end of the spring leaf will swing forward to push the formed spherical material away from the first forming groove for blanking, and can also block the subsequent output material to prevent it from escaping the first forming groove. After blanking is completed, the forming cover plate can be swung downward again until it abuts against the outer end surface of the end cover plate, allowing for rapid and repeated granulation of the bio-organic fertilizer, thereby effectively ensuring the granulation efficiency of the material.

[0019] 3) The forming cover plate on the inner side of the second forming groove of the present invention is respectively concavely provided with corresponding limiting grooves, and the limiting grooves are respectively fixedly installed with arc panels extending into the second forming groove through corresponding buffer rubber parts. After the material is squeezed to fill the spherical forming cavity formed by the second forming groove and the first forming groove, the buffer rubber parts are squeezed to the arc panels located in the corresponding limiting grooves, so as to form a reaction force on the material during the process of squeezing the material into the first forming groove and the second forming groove for granulation molding, thereby helping to improve the granulation molding effect of the material. When the forming cover plate swings upward to leave the end cover plate, the buffer rubber parts reset to form an outward driving force on the arc panels to push the formed material out of the second forming groove, so as to prevent the material from being fixedly embedded in the second forming groove and causing the subsequent material blanking to be unable to proceed normally, thereby effectively improving the practical effect of the present invention.

DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0028] Example 1: refer to Figure 1-6 , a bio-organic fertilizer granulation equipment, comprising: A fixed housing 1 is provided with at least one corresponding guide hole 101. A lower hopper 102 connected to the guide hole 101 is provided on the upper side of the fixed housing 1. An extrusion screw 2 is rotatably mounted at the guide hole 101. The extrusion screw 2 is driven by a corresponding driving mechanism 3. An end cover plate 4 with a plurality of discharge guide holes 401 provided on the periphery of the fixed housing 1 is fixedly mounted at the end of the fixed housing 1. The forming assembly 5 includes a forming cover plate 501 that is swingably mounted on the outer side of the end cover plate 4. The forming cover plate 501 is driven by a corresponding swing drive mechanism 502. The outer end surface of the end cover plate 4 is provided with a first forming groove 402 that is connected to the discharge guide hole 401. The inner end surface of the forming cover plate 501 is provided with a second forming groove 5011 that is compatible with the first forming groove 402. The multifunctional cutting assembly 6 includes a spring piece 601 that is movably inserted into the end cover plate 4 on the upper side of the first forming groove 402. The inner ends of the spring pieces 601 extend through the connection between the discharge guide hole 401 and the first forming groove 402. The outer ends of the spring pieces 601 are respectively fixedly connected to corresponding magnetic metal plates 602. The magnetic metal plates 602 are respectively fixed to the outer side of the end cover plate 4 via corresponding elastic members 603. The cutting drive mechanism 7 includes a plurality of magnets fixedly embedded on the forming cover plate 501 , and the magnets are respectively facing the magnetic metal plates 602 .

[0029] When the forming cover plate 501 swings downward until it abuts against the outer end surface of the end cover plate 4, the magnet parts respectively drive the corresponding magnetic metal plates 602 to attract each other, the elastic part 603 is compressed, and the spring sheet 601 leaves the connection between the discharge guide hole 401 and the first forming groove 402; when the forming cover plate 501 swings upward until it leaves the end cover plate 4, the elastic part 603 restores its deformation and drives the spring sheet 601 to reset it to the connection between the discharge guide hole 401 and the first forming groove 402, so as to cut the formed spherical material.

[0030] The present invention is based on the end cover plate 4 with many discharge guide holes 401 at the periphery, and further adds a forming component 5, a multifunctional cutting component 6 and a cutting drive mechanism 7, wherein the cutting drive mechanism 7 includes a plurality of magnet parts fixedly embedded on the forming cover plate 501 of the forming component 5, so that the forming and output of the material and the drive control of the cutting drive mechanism 7 can be synchronously adapted by flipping the forming cover plate 501. During the forming process, the forming cover plate 501 swings downward until it abuts against the outer end surface of the end cover plate 4, so that a corresponding forming space is formed between the first forming groove 402 and the second forming groove 5011. At this time, the magnets respectively drive the corresponding magnetic metal plates 602 to attract and drive the corresponding spring pieces 601 to leave the connection between the discharge guide hole 401 and the first forming groove 402, so as to facilitate the extrusion and output of the material. As the material is continuously extruded and output, it can effectively fill the space between the first forming groove 402 and the second forming groove 5011 for sufficient granulation and forming. After granulation and forming, the forming cover plate 501 swings upward to leave the end cover plate 4, and the elastic member 603 recovers its deformation and drives the corresponding spring piece 601 to return to the connection between the discharge guide hole 401 and the first forming groove 402, so as to cut the formed spherical material. In this way, it is possible to form a reasonable granulation process for the material and effectively ensure the granulation uniformity of the material, and it can also effectively and significantly reduce the breakage rate of the material after granulation.

[0031] The first molding groove 402 and the second molding groove 5011 are respectively spherical grooves with a half spherical shape. When the molding cover plate 501 swings downward to fit into the outer end surface of the end cover plate 4, the first molding groove 402 and the second molding groove 5011 are combined into an integral spherical molding cavity.

[0032] After the elastic member 603 recovers its deformation to drive the spring sheet 601 to cut the formed spherical material, the subsequently extruded material drives the end of the spring sheet 601 forward, and the end of the spring sheet 601 swings forward to push the formed spherical material away from the first forming groove 402 for blanking.

[0033] After the elastic member 603 of the present invention recovers its deformation to drive the corresponding spring piece 601 to cut the formed spherical material, the subsequently extruded material will drive the end of the spring piece 601 forward. At this time, the end of the spring piece 601 will swing forward to push the formed spherical material away from the first forming groove 402 for blanking, and can form a barrier to the subsequently output material to prevent the subsequently output material from escaping from the first forming groove 402. After blanking is completed, the forming cover plate 501 can be swung downward again to fit against the outer end surface of the end cover plate 4 to quickly repeat the granulation process of the bio-organic fertilizer, thereby effectively ensuring the granulation efficiency of the material.

[0034] Corresponding limiting grooves are respectively recessed on the forming cover plate 501 on the inner side of the second forming groove 5011, and arc panels 9 extending into the second forming groove 5011 are fixedly installed outwardly in the limiting grooves through corresponding buffer rubber parts 8. After the material is squeezed to fill the spherical forming cavity formed by the second forming groove 5011 and the first forming groove 402, the buffer rubber part 8 is squeezed until the arc panel 9 is located in the corresponding limiting groove.

[0035] When the forming cover plate 501 swings upward to leave the end cover plate 4 , the buffer rubber member 8 returns to its original position to form an outward driving force on the arc panel 9 to push the formed material out of the second forming groove 5011 .

[0036] The forming cover plate 501 on the inner side of the second forming groove 5011 of the present invention is respectively concavely provided with corresponding limiting grooves. The limiting grooves are respectively fixedly installed with arc panels 9 extending into the second forming groove 5011 through corresponding buffer rubber parts 8. After the material is squeezed to fill the spherical forming cavity formed by the second forming groove 5011 and the first forming groove 402, the buffer rubber parts 8 are squeezed until the arc panels 9 are located in the corresponding limiting grooves. In the process of the material being squeezed into the first forming groove 402 and the second forming groove 5011 for granulation molding, a reaction force is formed on the material to assist in improving the granulation molding effect of the material. When the forming cover plate 501 swings upward to leave the end cover plate 4, the buffer rubber parts 8 return to the original position to form an outward driving force on the arc panels 9 to push the formed material out of the second forming groove 5011, thereby preventing the material from being fixedly embedded in the second forming groove 5011 and causing subsequent material blanking to be unable to proceed normally, thereby effectively improving the practical effect of the present invention.

[0037] The driving mechanism 3 includes a driving motor 301 and a reducer 302 connected to the output shaft end of the driving motor 301, and the extrusion screw 2 is connected to the output shaft end of the reducer 302; the swing driving mechanism 502 adopts a group of driving cylinders.

[0038] The extrusion end of the extrusion screw 2 can be rotatably mounted to the center of the end cover 4. The elastic member 603 is a magnetic metal coil spring, which is fixed to the outer side of the end cover 4 through a corresponding connecting plate 10.

[0039] Example 2: A bio-organic fertilizer granulation method, based on the bio-organic fertilizer granulation equipment described in the first embodiment, comprises the following specific steps: S1, the organic fertilizer material enters the guide hole 101 of the fixed housing 1 through the lower hopper 102, and the extrusion screw 2 rotates to transport the organic fertilizer material and press it into the discharge guide hole 401 of the end cover plate 4 in an extruded state; S2, the forming cover plate 501 swings downward until it abuts against the outer end surface of the end cover plate 4, the magnet member attracts and drives the corresponding magnetic metal plate 602, and the spring piece 601 leaves the connection between the discharge guide hole 401 and the first forming groove 402; S3, the organic fertilizer material is squeezed into the first forming groove 402 and the second forming groove 5011 to form granular material; S4, the forming cover plate 501 swings upward to leave the end cover plate 4, and the elastic member 603 recovers its deformation to drive the spring sheet 601 to return to the junction of the discharge guide hole 401 and the first forming groove 402, so as to cut the formed spherical material; S5, the cut granular material rolls down through the first forming trough 402 and is discharged.

[0040] In the process of granulating the bio-organic fertilizer by the second embodiment of the present invention, the granulation efficiency is relatively high, and the granulation uniformity of the material can be effectively ensured and the breakage rate of the material after granulation can be effectively greatly reduced, thereby effectively ensuring the quality of the bio-organic fertilizer after granulation.
