Description

Technical Field

[0001] This invention relates to the field of fertilizer production technology, and in particular to an apparatus for producing organic-inorganic compound fertilizer. Background Technology

[0002] Organic-inorganic compound fertilizer is a compound fertilizer that contains both organic matter and appropriate amounts of chemical fertilizer. It is made by fermenting organic materials such as manure and peat to render them harmless and effective, then adding appropriate amounts of chemical fertilizer, humic acid, amino acids or beneficial microorganisms, and then mixing them thoroughly. During this process, excess water needs to be removed to improve the subsequent granulation effect and ensure the quality of the final product.

[0003] However, there are usually some problems in the production of compound fertilizers. With the development of technology, technicians in related fields have also made a lot of optimizations to the production of compound fertilizers. In order to make a more accurate comparison, Chinese patent with publication number CN114504998A discloses an organic-inorganic compound fertilizer and preparation device, including a mixing box. A water inlet pipe is fixedly installed on the left side of the mixing box, and an installation box is fixedly installed at the bottom of the mixing box. A drive mechanism is set inside the installation box, and a stirring mechanism is set inside the mixing box. The stirring mechanism includes a stirring shaft, which is driven to rotate by the drive mechanism. Stirring blades are rotatably installed outside the stirring shaft. A connecting pipe is fixedly installed on the right side of the mixing box, and a fermentation mechanism is fixedly installed at the end of the connecting pipe away from the mixing box.

[0004] In the above-mentioned prior art, organic fertilizer and inorganic fertilizer are added to the mixing tank, and water is added at the same time. The driving mechanism drives the mixing shaft to rotate, so that the mixing shaft drives the mixing blades to mix the inorganic fertilizer and organic fertilizer evenly. Then, the mixture in the mixing tank is discharged into the fermentation mechanism through the connecting pipe, so that the fermentation mechanism agitates the mixture and makes the mixture fully fermented. After fermentation is completed, the mixed fertilizer is discharged.

[0005] However, the aforementioned existing technologies still have some shortcomings in the production of compound fertilizers:

[0006] 1. Since the fermented mixed fertilizer needs to be mixed with appropriate amounts of chemical fertilizer, humic acid, amino acids or beneficial microorganisms to form the final compound fertilizer, the existing technology only involves stirring and fermenting the mixture, but cannot stir and heat the fermented mixed fertilizer accordingly. Therefore, additional steps are required to complete the final production of compound fertilizer, which wastes costs and affects production efficiency.

[0007] 2. Furthermore, since the organic raw materials of compound fertilizers usually contain a large amount of water, when the above-mentioned existing technology is used to stir the mixture, the mixture is easy to adhere to the inner wall of the mixing tank. The stirring blades cannot scrape off the mixture remaining on the inner wall of the mixing tank, which easily leads to the mixture inside the mixing tank not being completely discharged, and affects the mixing uniformity of the mixture, thus affecting the mixing effect. Moreover, the residual mixture is difficult to clean after it solidifies.

[0008] 3. In addition, after the compound fertilizer is produced, it needs to be dried and granulated for easy storage and transportation. However, the existing technology mentioned above cannot granulate the compound fertilizer and cannot make the compound fertilizer into different forms according to actual needs, thus affecting the actual use effect.

[0009] Therefore, based on the above-mentioned viewpoints, there is still room for improvement in existing compound fertilizer mixing methods. Summary of the Invention

[0010] To address the aforementioned problems, this invention provides an organic-inorganic compound fertilizer production device, comprising a support frame on which a mixing cylinder is mounted. A feed cylinder and a discharge cylinder, connected to the upper and lower ends of the mixing cylinder, are respectively mounted and communicate with it. The axes of both the feed cylinder and the discharge cylinder are perpendicular to the axis of the mixing cylinder, and both the feed cylinder and the discharge cylinder have bent sections connected to the mixing cylinder.

[0014] Preferably, the fixed plate located inside the feed cylinder has a vertical section, a horizontal section and an inclined section. The bending section of the inner wall of the feed cylinder is respectively provided with a vertical section and a horizontal section. An inclined section is installed between the vertical section and the horizontal section. There is a gap between the inclined section and the inner wall of the bending section for conveying the compound fertilizer raw materials from the feed cylinder to the mixing cylinder.

[0015] The fixed plate inside the discharge cylinder has an inclined section on the upper side and a vertical section on the lower side. The vertical section is installed on the inner bottom wall of the bending section of the discharge cylinder. There is a gap between the inclined section and the inner wall of the bending section of the discharge cylinder to guide the compound fertilizer raw materials from the mixing cylinder to the discharge cylinder.

[0016] Preferably, the dewatering assembly includes a drain outlet located at the bottom of the feed cylinder and below the spiral blades, a filter screen is provided on the inner wall of the drain outlet, and a water receiving cylinder is detachably installed on the upper end of the support, with the water receiving cylinder located below the drain outlet.

[0017] Preferably, the crushing assembly includes a receiving plate rotatably sleeved on the outer wall of the auxiliary shaft. The receiving plate is located at the connection between the bent section of the feed cylinder and the mixing cylinder, and the receiving plate is evenly provided with a plurality of annularly distributed material passage holes.

[0018] The outer wall of the auxiliary shaft is also fitted with a sleeve located above the receiving plate. Multiple annularly distributed shredding groups are evenly arranged on the outer wall of the sleeve. Each shredding group includes two symmetrically distributed rotary cutters. The distance between the two rotary cutters in the same shredding group and the side away from the sleeve gradually increases.

[0019] Preferably, the stirring and mixing unit further includes guide cylinders, with two guide cylinders provided on both the upper and lower sides of the inner wall of the mixing cylinder. The middle of the guide cylinder has an annular hole that fits outside the auxiliary shaft, and the guide cylinder is located above the mixing disk.

[0020] There are two mixing discs, which are fixedly sleeved on the outer wall of the auxiliary shaft. There are stirring teeth between the mixing discs and the guide cylinder for mixing the compound fertilizer raw materials. The stirring teeth between the mixing discs and the guide cylinder are staggered.

[0021] Preferably, the guide cylinder is composed of two tapered cylinders symmetrically distributed vertically. The distance between the two tapered cylinders of the same guide cylinder gradually decreases towards the side closer to the auxiliary shaft. The side of the upper tapered cylinder closer to the axis of the auxiliary shaft and the side of the lower tapered cylinder farther from the axis of the auxiliary shaft are both inclined downwards.

[0022] The mixing disc gradually tilts downwards on the side away from the auxiliary shaft axis, and the distance between the lower conical cylinder and the mixing disc gradually decreases on the side away from the auxiliary shaft axis. Multiple annularly distributed discharge ports are evenly opened on the outer edge of the mixing disc.

[0023] Preferably, multiple heating rods are evenly arranged circumferentially between the lower conical cylinder and the upper end of the mixing disk, and are distributed alternately with the stirring teeth.

[0024] Preferably, the diameter of the transmission bevel gear is larger than the diameter of the linkage bevel gear.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] I. This invention, through the cooperation between the rotating shaft, transmission bevel gear, linkage shaft, linkage bevel gear, and auxiliary shaft, can control the spiral blades inside the feed cylinder and discharge cylinder to rotate in opposite directions simultaneously. This allows the compound fertilizer raw materials to be conveyed towards the mixing cylinder while the mixed compound fertilizer is conveyed away from the mixing cylinder, thus achieving simultaneous feeding and discharging of compound fertilizer raw materials. This facilitates uninterrupted continuous production of compound fertilizer, thereby improving production efficiency.

[0027] Second, the present invention uses spiral blades to squeeze and dehydrate the raw materials of compound fertilizer during the transportation process, thereby effectively removing excess water from the raw materials of compound fertilizer, ensuring the overall quality of the finished compound fertilizer, and preventing water from affecting the use effect of compound fertilizer.

[0028] Third, the present invention uses a receiving plate to receive the compound fertilizer raw material after extrusion and dehydration. Then, the auxiliary shaft drives the rotary cutter to rotate synchronously through the sleeve and crushes the blocky compound fertilizer raw material accumulated on the upper part of the receiving plate into powder. The powder then falls into the mixing cylinder through the material hole to be stirred and mixed, so as to ensure the uniformity of the mixing of the powdery compound fertilizer raw material and prevent the compound fertilizer raw material from being unevenly mixed and affecting the use effect.

[0029] Fourth, this invention uses an auxiliary shaft to drive the mixing disc and guide cylinder to rotate relative to each other, and drives the stirring teeth to stir and mix the compound fertilizer raw materials. At the same time, the heating rod heats and dries the compound fertilizer raw materials, thereby avoiding the compound fertilizer raw materials from clumping or sticking to the inner wall of the mixing cylinder during the stirring and mixing process, which is difficult to clean. This makes it easier to mix them into compound fertilizer. Moreover, the two sets of guide cylinders and mixing discs distributed at the top and bottom can enhance the stirring and mixing effect of the compound fertilizer raw materials.

[0030] Fifth, when the rotating cover is adjusted to connect the through hole and the discharge port, the compound fertilizer is discharged normally in the form of finely mixed powder, which is convenient for direct use. When the rotating cover is adjusted to connect the granulation port and the discharge port, the compound fertilizer will be squeezed into thin strips after passing through the extrusion hole during the discharge process, and then cut into granules of a specified length by the cutting blade, thereby realizing the granulation of the compound fertilizer, which is convenient for the storage and transportation of the compound fertilizer. This can change the discharge form of the compound fertilizer so as to adapt to the actual production needs and improve adaptability. Attached Figure Description

[0042] The following is in conjunction with the appendix Figures 1-9 The embodiments of the present invention will be described in detail below.

[0043] This application discloses an organic-inorganic compound fertilizer production device. It should be noted that this device is mainly used in the production of compound fertilizers. Technically, it can simultaneously feed, mix, and discharge compound fertilizer raw materials, thereby achieving uninterrupted continuous production and improving production efficiency. Specifically, during the feeding process, it can precisely squeeze and dehydrate the raw materials, effectively removing excess moisture and ensuring the overall quality of the finished compound fertilizer. Furthermore, this device can crush the squeezed and dehydrated raw materials into powder, then heat, dry, and mix them, preventing clumping or adhesion to the inner wall of the mixing drum 2 during mixing and enhancing the mixing effect. Additionally, the device can adjust the discharge form of the compound fertilizer, allowing for direct discharge of the powdered compound fertilizer or granulation during discharge, adapting to actual production needs.

[0044] Example 1:

[0045] Reference Figure 1 and Figure 2 As shown, an organic-inorganic compound fertilizer production device includes a support 1, on which a mixing cylinder 2 is installed. A feed cylinder 3 and a discharge cylinder 4, which are connected to the upper and lower ends of the mixing cylinder 2, are respectively installed. The axes of the feed cylinder 3 and the discharge cylinder 4 are perpendicular to the axis of the mixing cylinder 2, and both the feed cylinder 3 and the discharge cylinder 4 have a bent section connected to the mixing cylinder 2. An inlet cylinder 31, which is connected to the upper end of the feed cylinder 3, is installed. A discharge port 41 is opened at the end of the discharge cylinder 4 away from the mixing cylinder 2.

[0046] The feed cylinder 3 is equipped with a conveying unit 5 for conveying the compound fertilizer raw materials and squeezing out the water. The conveying unit 5 includes a spiral blade 51 that is rotatably installed inside the feed cylinder 3 and the discharge cylinder 4. The mixing cylinder 2 is equipped with a stirring and mixing unit 6, which includes a mixing disc 61 installed inside the mixing cylinder 2.

[0047] In the specific implementation process, the fermented compound fertilizer raw materials, chemical fertilizers, humic acid, amino acids or beneficial microorganisms are poured into the feeding cylinder 3 through the feeding cylinder 31 in a specified ratio. Then, the compound fertilizer raw materials are conveyed from the feeding cylinder 3 to the mixing cylinder 2 through the conveying unit 5. During this period, the conveying unit 5 can squeeze out excess water from the compound fertilizer raw materials to ensure the overall quality of the compound fertilizer and prevent the water in the compound fertilizer from affecting the granulation and use effect of the compound fertilizer. Then, the drained compound fertilizer raw materials are heated, dried and stirred through the stirring and mixing unit 6 to mix the various raw materials evenly and make a usable compound fertilizer. The compound fertilizer can then be discharged and used directly.

[0048] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in order to facilitate the production of the fermented compound fertilizer raw materials into the final compound fertilizer and to ensure the quality of the compound fertilizer, it is necessary to squeeze out the water from the compound fertilizer raw materials first. Based on this, in this embodiment, the inner walls of the bent sections of the feed cylinder 3 and the discharge cylinder 4 are both equipped with fixing plates 32. The conveying unit 5 also includes a rotating shaft 52 and a linkage shaft 53 that are rotatably installed inside the feed cylinder 3 and the discharge cylinder 4, respectively. The outer walls of the rotating shaft 52 and the linkage shaft 53 are both equipped with spiral blades 51. The feed cylinder 3 is equipped with a dehydration component 54 for squeezing out the water from the compound fertilizer raw materials, and the bent section of the feed cylinder 3 is equipped with a crushing component 55.

[0049] It should be noted that in this embodiment, the spiral blades 51 on the outer walls of the rotating shaft 52 and the linkage shaft 53 rotate in the same direction, and the inner walls of the feed cylinder 3 and the discharge cylinder 4 abut against the outer wall of the spiral blades 51. This is to prevent the spiral blades 51 from having gaps with the inner walls of the feed cylinder 3 or the discharge cylinder 4 when conveying compound fertilizer raw materials, thus affecting the conveying efficiency. It also prevents the compound fertilizer raw materials from adhering to the inner walls of the feed cylinder 3 and the discharge cylinder 4 and becoming difficult to clean.

[0050] Furthermore, in this embodiment, both the rotating shaft 52 and the linkage shaft 53 rotate through the fixed plate 32 and are fixedly fitted with a transmission bevel gear 56. An auxiliary shaft 57 rotates through the upper and lower fixed plates 32 together. Both ends of the auxiliary shaft 57 are fixedly fitted with linkage bevel gears 58 that mesh with the transmission bevel gear 56. The end of the feed cylinder 3 away from the mixing cylinder 2 is equipped with a positioning motor 59 connected to the rotating shaft 52 via a motor base.

[0051] In the specific implementation process, the positioning motor 59 is started, and the positioning motor 59 drives the spiral blades 51 on its outer wall to rotate through the rotating shaft 52. Then, various raw materials are poured into the feeding cylinder 3 so that the spiral blades 51 can transport the compound fertilizer raw materials to the mixing cylinder 2. At the same time, the dehydration component 54 can squeeze out the excess water in the compound fertilizer raw materials to avoid affecting the quality of the compound fertilizer. Then, the crushing component 55 crushes the dehydrated compound fertilizer raw materials and discharges them into the mixing cylinder 2 to ensure the mixing efficiency of the stirring and mixing unit 6.

[0052] Furthermore, during the rotation of the rotating shaft 52, the transmission bevel gear 56 rotates synchronously. Through the cooperation between the transmission bevel gear 56, the linkage bevel gear 58, and the auxiliary shaft 57, the linkage shaft 53 and the spiral blades 51 on its outer wall can rotate simultaneously. Moreover, the rotating shaft 52 and the spiral blades 51 on the outer wall of the linkage shaft 53 rotate in opposite directions. Thus, when the spiral blades 51 inside the feed cylinder 3 rotate to convey the compound fertilizer raw materials to the side closer to the mixing cylinder 2, the spiral blades 51 inside the discharge cylinder 4 convey the mixed compound fertilizer to the side away from the mixing cylinder 2 and discharge it through the discharge port 41. In this way, the simultaneous feeding and discharging of the compound fertilizer raw materials is achieved through the two spiral blades 51 rotating in opposite directions. This facilitates the continuous production of compound fertilizer raw materials in conjunction with the mixing unit 6, thereby improving production efficiency.

[0053] Continue to refer to Figure 2 and Figure 3 As shown, to prevent the compound fertilizer raw materials from being smeared on the transmission bevel gear 56 and the linkage bevel gear 58 during the conveying process and affecting normal linkage, in this embodiment, the fixed plate 32 located inside the feed cylinder 3 is composed of a vertical section, a horizontal section and an inclined section. The bending section of the inner wall of the feed cylinder 3 is respectively provided with a vertical section and a horizontal section, and an inclined section is installed between the vertical section and the horizontal section. There is a gap between the inclined section and the inner wall of the bending section for conveying the compound fertilizer raw materials from the feed cylinder 3 to the mixing cylinder 2. The fixed plate 32 inside the discharge cylinder 4 has an inclined section and a vertical section on its upper and lower sides, respectively. The vertical section is installed on the inner bottom wall of the bending section of the discharge cylinder 4, and there is a gap between the inclined section and the inner wall of the bending section of the discharge cylinder 4 for guiding the compound fertilizer raw materials from the mixing cylinder 2 to the discharge cylinder 4.

[0054] In practical applications, the gaps between the two fixing plates 32 and the feed cylinder 3 and the discharge cylinder 4 can form a channel, allowing the compound fertilizer raw materials in the feed cylinder 3 to be smoothly discharged into the mixing cylinder 2 through the channel. The compound fertilizer that has been mixed in the mixing cylinder 2 enters the discharge cylinder 4 through the channel for easy discharge. Furthermore, the fixing plates 32 can protect the transmission bevel gear 56 and the linkage bevel gear 58, preventing the compound fertilizer raw materials from adhering to the outer walls of the transmission bevel gear 56 and the linkage bevel gear 58 and causing corrosion that would affect normal use.

[0055] Reference Figure 5 As shown, in order to avoid the moisture in the compound fertilizer raw materials from affecting the quality of the compound fertilizer and the granulation effect, it is necessary to remove the excess moisture in the compound fertilizer raw materials. Based on this, a dehydration component 54 is also provided in this embodiment. Specifically, the dehydration component 54 includes a drain outlet 541 opened at the bottom of the feed cylinder 3 and located below the spiral blade 51. A filter screen 542 is provided on the inner wall of the drain outlet 541. A water receiving cylinder 543 is detachably installed on the upper end of the support 1 and is located below the drain outlet 541.

[0056] In the specific implementation process, the rotating shaft 52 drives the spiral blades 51 on its outer wall to rotate, and during the process of conveying the compound fertilizer raw materials into the mixing cylinder 2, it can apply extrusion pressure to the compound fertilizer raw materials, so as to squeeze and dehydrate them during the conveying process. The squeezed water flows down through the filter screen 542 into the water receiving cylinder 543, thereby effectively removing excess water from the compound fertilizer raw materials, ensuring the overall quality of the finished compound fertilizer, and preventing water from affecting the use effect of the compound fertilizer. After the water receiving cylinder 543 is full of water, it can be removed and the water poured out.

[0057] Reference Figure 4 As shown, since the compound fertilizer raw materials after extrusion and dehydration are prone to sticking together into lumps under external force, it is difficult to mix them evenly. Therefore, it is necessary to crush the compound fertilizer raw materials after extrusion and dehydration into powder for mixing. Based on this, a crushing component 55 is also provided in this embodiment. Specifically, the crushing component 55 includes a receiving plate 551 rotatably sleeved on the outer wall of the auxiliary shaft 57. The receiving plate 551 is located at the connection between the bent section of the feed cylinder 3 and the mixing cylinder 2. Multiple annularly distributed material passage holes 552 are evenly opened on the receiving plate 551.

[0058] Furthermore, in this embodiment, the outer wall of the auxiliary shaft 57 is also fixedly sleeved with a sleeve 553 located above the receiving plate 551. The outer wall of the sleeve 553 is uniformly provided with a plurality of annularly distributed shredding groups. Each shredding group includes two vertically symmetrically distributed rotary cutters 554. The distance between the two rotary cutters 554 in the same shredding group on the side away from the sleeve 553 gradually increases.

[0059] In the specific implementation process, the compound fertilizer raw material after extrusion and dehydration falls downward and accumulates on the upper end of the receiving plate 551. During the rotation of the rotating shaft 52, the auxiliary shaft 57 is driven to rotate synchronously through the transmission bevel gear 56 and the linkage bevel gear 58. The auxiliary shaft 57 drives the rotary cutter 554 to rotate synchronously through the sleeve 553. Thus, the rotary cutter 554 can break the blocky compound fertilizer raw material accumulated on the upper end of the receiving plate 551 into powder. The powdered compound fertilizer raw material falls into the mixing cylinder 2 through the material hole 552 to be stirred and mixed, so as to ensure the uniformity of the mixing of the powdered compound fertilizer raw material and prevent the compound fertilizer raw material from being unevenly mixed and affecting the use effect.

[0060] It should be noted that the diameter of the transmission bevel gear 56 is larger than that of the linkage bevel gear 58. By using transmission bevel gear 56 and linkage bevel gear 58 with different diameters, the rotation speed of the auxiliary shaft 57 can be greater than that of the rotating shaft 52, thereby ensuring that the auxiliary shaft 57 drives the rotary cutter 554 to rotate rapidly, so as to improve the crushing efficiency of blocky compound fertilizer raw materials.

[0061] Reference Figure 6 and Figure 7As shown, in order to facilitate the mixing of multiple raw materials into compound fertilizer, a mixing unit 6 is also provided in this embodiment. Specifically, the mixing unit 6 also includes a guide cylinder 62. Two guide cylinders 62 are provided on the upper and lower sides of the inner wall of the mixing cylinder 2. The middle of the guide cylinder 62 is an annular hole 63 that is sleeved on the outside of the auxiliary shaft 57. The guide cylinder 62 is located above the mixing disc 61. The guide cylinder 62 is fixedly installed on the inner wall of the mixing cylinder 2. The guide cylinder 62 and the annular hole 63 facilitate the guidance of the compound fertilizer raw materials, so that the compound fertilizer raw materials can fall smoothly onto the upper end of the mixing disc 61. There are two mixing discs 61, and the mixing discs 61 are fixedly sleeved on the outer wall of the auxiliary shaft 57. A stirring tooth 64 for mixing the compound fertilizer raw materials is installed between the mixing disc 61 and the guide cylinder 62. The stirring tooth 64 between the mixing disc 61 and the guide cylinder 62 is staggered.

[0062] Furthermore, in this embodiment, the guide cylinder 62 is composed of two tapered cylinders symmetrically distributed vertically. The distance between the two tapered cylinders of the same guide cylinder 62 gradually decreases towards the side closer to the auxiliary shaft 57, so that the side of the upper tapered cylinder closer to the axis of the auxiliary shaft 57 and the side of the lower tapered cylinder away from the axis of the auxiliary shaft 57 are both inclined downwards. The side of the mixing disk 61 away from the axis of the auxiliary shaft 57 gradually inclines downwards, and the distance between the lower tapered cylinder and the mixing disk 61 gradually decreases towards the side away from the axis of the auxiliary shaft 57. Multiple annularly distributed discharge ports 65 are uniformly opened at the outer edge of the mixing disk 61.

[0063] In addition, in order to facilitate the mixing efficiency of compound fertilizer raw materials, in this embodiment, multiple heating rods 66 are uniformly arranged circumferentially between the lower conical cylinder and the upper end of the mixing disk 61, and are staggered with the stirring teeth 64.

[0064] In the specific implementation process, the auxiliary shaft 57 drives the rotary cutter 554 to rotate during the crushing of the blocky compound fertilizer raw materials. The auxiliary shaft 57 drives the mixing disc 61 to rotate synchronously, so that the mixing disc 61 and the guide cylinder 62 rotate relative to each other. When the crushed compound fertilizer raw materials fall downward, they fall to the upper end of the mixing disc 61 under the guidance of the guide cylinder 62. Then, the mixing disc 61 and the guide cylinder 62 drive the stirring teeth 64 to stir and mix the compound fertilizer raw materials. At the same time, the heating rod 66 is activated to heat and dry the compound fertilizer raw materials, thereby avoiding the compound fertilizer raw materials from clumping or sticking to the inner wall of the mixing cylinder 2 during the stirring and mixing process, which is difficult to clean. This results in the compound fertilizer raw materials after stirring and mixing forming dry crushed materials.

[0065] In addition, the two sets of guide cylinders 62 and mixing discs 61 distributed vertically can enhance the mixing effect of the compound fertilizer raw materials, thereby mixing them into compound fertilizer. The mixed compound fertilizer then falls downward through the discharge port 65 and is discharged into the discharge cylinder 4, so that the spiral blades 51 inside the discharge cylinder 4 can transport the compound fertilizer to the side away from the mixing cylinder 2.

[0066] Example 2:

[0067] Reference Figure 8 and Figure 9 As shown in Example 1, in order to improve the application and storage effects of the compound fertilizer, it is necessary to granulate the produced compound fertilizer. Based on this, this example also provides a corresponding granulation unit 7, which is specifically as follows:

[0068] The granulation unit 7 includes a rotating cover 71 that is rotatably sleeved on the end of the discharge cylinder 4 away from the mixing cylinder 2. The discharge cylinder 4 has a plurality of annularly distributed discharge ports 41 evenly distributed on the side away from the mixing cylinder 2. The rotating cover 71 has a plurality of through holes 72 corresponding to the positions of the discharge ports 41. The rotating cover 71 has a plurality of connecting grooves 73 arranged alternately with the through holes 72 inside.

[0069] Furthermore, in this embodiment, the connecting groove 73 is provided with a plurality of extrusion holes 74 on the side near the discharge cylinder 4, and the rotating cover 71 is provided with a plurality of particle outlets 75 connected to the connecting groove 73 on the side away from the discharge cylinder 4. A cutting blade 76 is slidably arranged inside the connecting groove 73, and a rotating ring 77 is rotatably arranged inside the rotating cover 71. One end of the plurality of cutting blades 76 is connected to the rotating ring 77, and the other end is fitted with a gear ring 78 that is rotatably sleeved on the outer wall of the rotating cover 71. A forward and reverse motor 79 is provided on the outer wall of the rotating cover 71 through a motor frame, and a gear 70 that meshes with the gear ring 78 is sleeved on the output shaft of the forward and reverse motor 79.

[0070] In the specific implementation process, the rotating cover 71 is controlled to rotate so that the through hole 72 is connected to the discharge port 41 of the discharge cylinder 4. At this time, the compound fertilizer is discharged normally from the discharge cylinder 4, and the discharged compound fertilizer is in the form of powder, so that it can be used directly.

[0071] Furthermore, the rotating cover 71 is rotated to connect the connecting groove 73, the granulation port 75, and the discharge port 41 of the discharge cylinder 4. At this time, the forward and reverse motor 79 is started. The forward and reverse motor 79 drives the gear ring 78 to rotate alternately in the forward and reverse directions through the gear 70, so that the gear ring 78 drives the cutting blade 76 to swing back and forth in the connecting groove 73. When the spiral blade 51 discharges the compound fertilizer from the discharge port 41, the compound fertilizer will be extruded into thin strips after passing through the extrusion hole 74. At this time, the extruded compound fertilizer can be cut into granules of a specified length by the cutting blade 76, thereby realizing the granulation of compound fertilizer, so as to facilitate the storage and transportation of compound fertilizer.

[0072] In summary, by rotating the rotating cover 71 to connect the through hole 72 and the granulation outlet 75 to the discharge outlet 41, the discharge pattern of the compound fertilizer can be changed, so as to adapt to the actual production needs and thus improve adaptability.

[0073] It should be noted that a damping ring (not shown in the figure) is provided between the rotating cover 71 and the discharge cylinder 4. The damping ring can limit the rotation of the rotating cover 71 to prevent it from rotating arbitrarily after rotation adjustment, which would affect the alignment between the through hole 72 or the particle outlet 75 and the discharge port 41.

[0074] During operation: Step 1: Start the positioning motor 59. The positioning motor 59 drives the spiral blades 51 on its outer wall to rotate through the rotating shaft 52.

[0075] Step 2: The fermented compound fertilizer raw materials, chemical fertilizers, humic acid, amino acids or beneficial microorganisms are poured into the feed cylinder 3 through the feed cylinder 31 in a specified ratio, and the compound fertilizer raw materials are conveyed to the mixing cylinder 2 through the spiral blades 51.

[0076] Step 3: The rotating shaft 52 drives the spiral blades 51 on its outer wall to rotate, conveying the compound fertilizer raw materials into the mixing drum 2. During this process, it can apply extrusion pressure to the compound fertilizer raw materials, which facilitates the dehydration of the raw materials during the conveying process. The squeezed water flows down through the filter screen 542 into the water receiving drum 543, which can effectively remove excess water from the compound fertilizer raw materials, thereby ensuring the overall quality of the finished compound fertilizer and preventing water from affecting the use effect of the compound fertilizer. After the water receiving drum 543 is full, it can be removed and the water poured out.

[0077] Step 4: After being squeezed and dehydrated, the compound fertilizer raw material falls downward and accumulates on the upper end of the receiving plate 551. During the rotation of the rotating shaft 52, the auxiliary shaft 57 is driven to rotate synchronously through the transmission bevel gear 56 and the linkage bevel gear 58. The auxiliary shaft 57 drives the rotary cutter 554 to rotate synchronously through the sleeve 553. Thus, the rotary cutter 554 can break the blocky compound fertilizer raw material accumulated on the upper end of the receiving plate 551 into powder. The powdered compound fertilizer raw material falls into the mixing drum 2 through the material hole 552 to be stirred and mixed, so as to ensure the uniformity of the mixing of the powdered compound fertilizer raw material and prevent the compound fertilizer raw material from being unevenly mixed and affecting the use effect.

[0078] Step 5: During the rotation of the auxiliary shaft 57, the mixing disc 61 rotates synchronously, so that the mixing disc 61 and the guide cylinder 62 rotate relative to each other. When the crushed compound fertilizer raw material falls downward, it falls to the upper end of the mixing disc 61 under the guidance of the guide cylinder 62. Then, the mixing disc 61 and the guide cylinder 62 drive the stirring teeth 64 to stir and mix the compound fertilizer raw material. At the same time, the heating rod 66 is activated to heat and dry the compound fertilizer raw material, thereby avoiding the compound fertilizer raw material from clumping or sticking to the inner wall of the mixing cylinder 2 during the stirring and mixing process, which is difficult to clean. This results in the compound fertilizer raw material after stirring and mixing forming a dry crushed state.

[0079] In addition, the two sets of guide cylinders 62 and mixing discs 61 distributed vertically can enhance the mixing effect of the compound fertilizer raw materials, thereby mixing them into compound fertilizer. The mixed compound fertilizer then falls downward through the discharge port 65 and is discharged into the discharge cylinder 4, so that the spiral blades 51 inside the discharge cylinder 4 can transport the compound fertilizer to the side away from the mixing cylinder 2.

[0080] Step 6: When the auxiliary shaft 57 rotates, the engagement between the transmission bevel gear 56 and the linkage bevel gear 58 can drive the linkage shaft 53 and the spiral blades 51 on its outer wall to rotate simultaneously, so as to discharge the compound fertilizer in the discharge cylinder 4.

[0081] Furthermore, the spiral blades 51 on the outer walls of the rotating shaft 52 and the linkage shaft 53 rotate in opposite directions. Thus, when the spiral blades 51 inside the feed cylinder 3 rotate to convey the compound fertilizer raw materials to the side closer to the mixing cylinder 2, the spiral blades 51 inside the discharge cylinder 4 convey the mixed compound fertilizer to the side away from the mixing cylinder 2 and discharge it through the discharge port 41. In this way, the simultaneous feeding and discharging of the compound fertilizer raw materials is achieved through the two spiral blades 51 rotating in opposite directions. This facilitates the continuous production of compound fertilizer raw materials in conjunction with the mixing unit 6, thereby improving production efficiency.

[0082] Step 7: When the rotating cover 71 is rotated to connect the through hole 72 with the discharge port 41, the compound fertilizer is discharged normally and is in the form of powder after mixing, so that it can be used directly; when the rotating cover 71 is rotated to connect the granulation port 75 with the discharge port 41, the compound fertilizer will be squeezed into thin strips after passing through the extrusion hole 74 during the discharge process.

[0083] At this time, the forward and reverse motor 79 is started. The forward and reverse motor 79 drives the gear ring 78 to rotate alternately in the forward and reverse directions through the gear 70. This causes the gear ring 78 to drive the cutting blade 76 to swing back and forth in the connecting groove 73. The cutting blade 76 can cut the thin strip-shaped compound fertilizer that passes through the extrusion hole 74 into granules of a specified length, thereby realizing the granulation of compound fertilizer, which is convenient for the storage and transportation of compound fertilizer. This can change the discharge form of compound fertilizer, so as to adapt to the actual production needs and improve adaptability.
