Description

Technical Field

[0001] The invention relates to the technical field of fertilizer production, and in particular to an organic-inorganic compound fertilizer production device. Background Art

[0002] Organic-inorganic compound fertilizer is a kind of compound fertilizer containing both organic matter and appropriate amount of fertilizer. It is made by fermenting organic materials such as feces and peat to make them harmless and effective, and then adding appropriate amount of fertilizer, humic acid, amino acid or beneficial microorganisms, and then fully mixing them. During this period, 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 science and technology, technicians in related fields have also made a lot of optimizations on the production of compound fertilizers. In order to make a more accurate comparison, a Chinese patent with publication number CN114504998A discloses an organic-inorganic compound fertilizer and a preparation device, including a mixing box, a water inlet pipe is fixedly installed on the left side of the mixing box, a mounting box is fixedly installed on the bottom of the mixing box, a driving mechanism is arranged inside the mounting box, a mixing mechanism is arranged inside the mixing box, the mixing mechanism includes a mixing shaft, the mixing shaft is driven to rotate by the driving mechanism, a mixing blade is rotatably installed on the outside of the mixing shaft, a connecting pipe is fixedly installed on the right side of the mixing box, and a fermentation mechanism is fixedly installed on the end of the connecting pipe away from the mixing box.

[0004] When the above-mentioned prior art is in use, organic fertilizer and inorganic fertilizer are added into the mixing box, and water is added into the mixing box 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 the organic fertilizer evenly. Then, the mixture in the mixing box is discharged into the fermentation mechanism through the connecting pipe, so that the fermentation mechanism stirs the mixture to make the mixture fully fermented; after the fermentation is completed, the mixed fertilizer is discharged.

[0005] However, the above-mentioned prior art still has some shortcomings in the process of producing compound fertilizer: 1. Since the fermented mixed fertilizer needs to be added with appropriate amount of fertilizer, humic acid, amino acid or beneficial microorganisms and then mixed to form the final compound fertilizer, the above-mentioned prior art only involves stirring, mixing and fermenting the mixture, but cannot perform corresponding stirring, mixing and heating and drying on the fermented mixed fertilizer, so that additional steps are required to complete the final production of the compound fertilizer, which wastes costs and affects production efficiency.

[0006] 2. Since the organic raw materials of compound fertilizers usually contain a large amount of water, when the above-mentioned prior art stirs the mixture, the mixture is easy to adhere to the inner wall of the mixing box, and the stirring blades cannot scrape off the residual mixture on the inner wall of the mixing box, which can easily lead to the inability to completely discharge the mixture inside the mixing box, and affect the mixing uniformity of the mixture, thereby affecting the mixing effect, and the residual mixture is difficult to clean after solidification.

[0007] 3. In addition, after the compound fertilizer is produced, it needs to be dried and granulated for easy storage and transportation. However, the above-mentioned prior art cannot realize the granulation of compound fertilizer, and cannot make compound fertilizer into fertilizers of different forms according to actual needs, thus affecting the actual use effect.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-Figure 9 Embodiments of the present invention are described in detail.

[0037] The embodiment of the present application discloses an organic-inorganic compound fertilizer production device. It should be noted that the organic-inorganic compound fertilizer production device of the present application is mainly used in the process of producing compound fertilizer. In terms of technical effect, the compound fertilizer raw materials can be fed, mixed and discharged at the same time, so as to realize uninterrupted and continuous production of compound fertilizer, thereby improving production efficiency; in particular, in the process of feeding the compound fertilizer raw materials, the compound fertilizer raw materials can be extruded and dehydrated in alignment during the process of conveying the compound fertilizer raw materials, so that the excess water in the compound fertilizer raw materials can be effectively removed, thereby ensuring the overall quality of the finished compound fertilizer; further, the organic-inorganic compound fertilizer production device can also crush the compound fertilizer raw materials after extrusion and dehydration into powder, and then heat, dry and stir and mix them, so as to avoid the compound fertilizer raw materials from agglomerating or adhering to the inner wall of the mixing barrel 2 during the stirring and mixing process, which is difficult to clean, and can enhance the stirring and mixing effect of the compound fertilizer raw materials; and in the process of discharging the compound fertilizer, the discharged form can be adjusted, that is, the compound fertilizer in the form of powder is directly discharged or granulated during the discharge process, so as to facilitate adaptive adjustment according to actual production needs.

[0038] Embodiment 1: Reference Figure 1 and Figure 2 As shown, an organic-inorganic compound fertilizer production device includes a bracket 1, a mixing barrel 2 is installed on the bracket 1, and a feed barrel 3 and a discharge barrel 4 connected to the mixing barrel 2 are respectively installed at the upper and lower ends of the mixing barrel 2, the axes of the feed barrel 3 and the discharge barrel 4 are perpendicular to the axis of the mixing barrel 2, and the feed barrel 3 and the discharge barrel 4 have a bending section connected to the mixing barrel 2, a feed barrel 31 connected to the mixing barrel is installed on the upper end of the feed barrel 3, and a discharge port 41 is provided at the end of the discharge barrel 4 away from the mixing barrel 2.

[0039] A conveying unit 5 for conveying the compound fertilizer raw material and squeezing out the water therein is arranged inside the feed barrel 3, and the conveying unit 5 includes a spiral blade 51 rotatably arranged inside the feed barrel 3 and the discharge barrel 4. A stirring and mixing unit 6 is installed inside the mixing barrel 2, and the stirring and mixing unit 6 includes a mixing disk 61 arranged inside the mixing barrel 2.

[0040] In the specific implementation process, the fermented compound fertilizer raw materials and chemical fertilizers, humic acid, amino acids or beneficial microorganisms are poured into the feeding barrel 3 through the feeding barrel 31 in a specified proportion, and then the compound fertilizer raw materials are transported from the feeding barrel 3 to the mixing barrel 2 through the conveying unit 5. During this period, the conveying unit 5 can squeeze out excess water in 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 and mixed by the stirring and mixing unit 6, so as to mix the various raw materials evenly and make them into a usable compound fertilizer, and then the compound fertilizer is discharged and can be used directly.

[0041] 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 in the compound fertilizer raw materials first. Based on this, in the present embodiment, the inner walls of the bending sections of the feed barrel 3 and the discharge barrel 4 are both equipped with fixed plates 32, and the conveying unit 5 also includes a rotating shaft 52 and a linkage shaft 53 rotatably installed inside the feed barrel 3 and the discharge barrel 4, respectively, and the outer walls of the rotating shaft 52 and the linkage shaft 53 are both equipped with spiral blades 51, and a dehydration component 54 for squeezing out the water in the compound fertilizer raw materials is arranged inside the feed barrel 3, and a crushing component 55 is installed inside the bending section of the feed barrel 3.

[0042] It should be noted that, in the present embodiment, the spiral blades 51 on the outer walls of the rotating shaft 52 and the linkage shaft 53 have the same rotation direction, and the inner walls of the feed barrel 3 and the discharge barrel 4 are both in contact with the outer walls of the spiral blades 51, so that when the spiral blades 51 are conveying the compound fertilizer raw materials, there is no gap between them and the inner walls of the feed barrel 3 or the discharge barrel 4, which affects the conveying efficiency, and it can prevent the compound fertilizer raw materials from adhering to the inner walls of the feed barrel 3 and the discharge barrel 4 and being difficult to clean.

[0043] Furthermore, in this embodiment, the rotating shaft 52 and the linkage shaft 53 are both rotated through the fixed plate 32 and fixedly sleeved with a transmission bevel gear 56, and an auxiliary shaft 57 is inserted and rotated between the upper and lower fixed plates 32 for common rotation. The upper and lower ends of the auxiliary shaft 57 are fixedly sleeved with linkage bevel gears 58 meshing with the transmission bevel gear 56, and a positioning motor 59 connected to the rotating shaft 52 is installed at one end of the feed barrel 3 away from the mixing barrel 2 through a motor seat.

[0044] During the specific implementation process, the positioning motor 59 is started, and the positioning motor 59 drives the spiral blade 51 on its outer wall to rotate through the rotating shaft 52, and then a variety of raw materials are poured into the feeding barrel 3, so that the spiral blade 51 can transport the compound fertilizer raw materials to the mixing barrel 2. At the same time, the excess water in the compound fertilizer raw materials can be squeezed out through the dehydration component 54 to avoid affecting the quality of the compound fertilizer; then the dehydrated compound fertilizer raw materials are crushed by the crushing component 55 and discharged into the mixing barrel 2 to ensure the mixing efficiency of the stirring and mixing unit 6.

[0045] In addition, the rotation of the rotating shaft 52 drives the transmission bevel gear 56 to rotate 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 the outer wall thereof can be driven to rotate simultaneously. The rotation directions of the spiral blades 51 on the outer wall of the rotating shaft 52 and the linkage shaft 53 are opposite. Therefore, when the spiral blades 51 inside the feeding barrel 3 rotate to transport the compound fertilizer raw materials to the side close to the mixing barrel 2, the spiral blades 51 inside the discharging barrel 4 transport the mixed compound fertilizer to the side away from the mixing barrel 2 and discharge it through the discharging port 41. Then, the compound fertilizer raw materials are fed and discharged simultaneously by the upper and lower spiral blades 51 with opposite rotation directions, so as to cooperate with the stirring and mixing unit 6 to realize uninterrupted and continuous production of the compound fertilizer raw materials, thereby improving production efficiency.

[0046] Continue to refer to Figure 2 and Figure 3 As shown, in order to prevent the compound fertilizer raw materials from being smeared on the transmission bevel gear 56 and the linkage bevel gear 58 during the transportation process and affecting the normal linkage, therefore, in the present embodiment, the fixed plate 32 located inside the feed barrel 3 is composed of a vertical section, a horizontal section and an inclined section, and the bending section of the inner wall of the feed barrel 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, and a gap is provided between the inclined section and the inner wall of the bent section for conveying the compound fertilizer raw materials from the feed barrel 3 to the mixing barrel 2; the upper and lower sides of the fixed plate 32 inside the discharge barrel 4 are respectively an inclined section and a vertical section, and the vertical section is installed on the inner bottom wall of the bent section of the discharge barrel 4, and a gap is provided between the inclined section and the inner wall of the bent section of the discharge barrel 4 for guiding the compound fertilizer raw materials from the mixing barrel 2 to the discharge barrel 4.

[0047] In actual application, a channel can be formed through the gap between the two fixed plates 32 and the feed barrel 3 and the discharge barrel 4, so that the compound fertilizer raw materials in the feed barrel 3 can be smoothly discharged into the mixing barrel 2 through the channel, and the compound fertilizer mixed in the mixing barrel 2 enters the discharge barrel 4 after passing through the channel for easy discharge; and the fixed plate 32 can protect the transmission bevel gear 56 and the linkage bevel gear 58 to prevent the compound fertilizer raw materials from adhering to the outer walls of the transmission bevel gear 56 and the linkage bevel gear 58 to cause corrosion and affect normal use.

[0048] Reference Figure 5 As shown, in order to prevent the moisture in the compound fertilizer raw material from affecting the quality of the compound fertilizer and the granulation effect, it is necessary to remove excess moisture in the compound fertilizer raw material. Based on this, a dehydration component 54 is also provided in this embodiment. Specifically, the dehydration component 54 includes a drain port 541 opened at the bottom of the feed barrel 3 and located below the spiral blade 51, a filter screen 542 is provided on the inner wall of the drain port 541, and a water receiving cylinder 543 is detachably installed on the upper end of the bracket 1, and the water receiving cylinder 543 is located below the drain port 541.

[0049] In the specific implementation process, the rotating shaft 52 drives the spiral blades 51 on its outer wall to rotate, and can exert an extrusion force on the compound fertilizer raw materials during the transportation of the compound fertilizer raw materials into the mixing drum 2, so as to facilitate the extrusion and dehydration of the compound fertilizer raw materials during the transportation process, so that the squeezed water flows downward through the filter screen 542 to the water receiving drum 543, thereby effectively removing excess water in the compound fertilizer raw materials, thereby ensuring the overall quality of the finished compound fertilizer, and preventing moisture from affecting the use effect of the compound fertilizer. After the water in the water receiving drum 543 is filled, it can be removed and the water can be poured out.

[0050] Reference Figure 4 As shown, since the compound fertilizer raw materials after extrusion and dehydration are easily bonded into blocks under the action of external force, it is difficult to mix them evenly. Therefore, the compound fertilizer raw materials after extrusion and dehydration need to be crushed into crumbs for stirring and 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 bending section of the feed barrel 3 and the mixing barrel 2, and a plurality of annularly distributed penetration holes 552 are evenly opened on the receiving plate 551.

[0051] 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, and the outer wall of the sleeve 553 is evenly provided with multiple annularly distributed shredding groups, and the shredding groups include two rotary cutters 554 symmetrically distributed up and down, and the distance between the two rotary cutters 554 of the same shredding group away from one side of the sleeve 553 gradually increases.

[0052] During the specific implementation process, the compound fertilizer raw materials after extrusion and dehydration fall downward and accumulate on the upper end of the receiving plate 551. During the rotation of the rotating shaft 52, the transmission bevel gear 56 cooperates with the linkage bevel gear 58 to drive the auxiliary shaft 57 to rotate synchronously. The auxiliary shaft 57 drives the rotary cutter 554 to rotate synchronously through the sleeve 553, so that the block compound fertilizer raw materials accumulated on the upper end of the receiving plate 551 can be broken into crumbs by the rotary cutter 554, so that the crumbs of the compound fertilizer raw materials fall into the mixing barrel 2 through the feeding hole 552 to be stirred and mixed, so as to ensure the mixing uniformity of the crushed compound fertilizer raw materials and prevent the compound fertilizer raw materials from being unevenly mixed and affecting the use effect.

[0053] It should be noted that the diameter of the transmission bevel gear 56 is greater than the diameter of the linkage bevel gear 58. The transmission bevel gears 56 and the linkage bevel gears 58 of different diameters can make the rotation speed of the auxiliary shaft 57 greater than the rotation speed of the rotating shaft 52, thereby ensuring that the auxiliary shaft 57 drives the rotary cutter 554 to rotate quickly, so as to improve the chopping efficiency of the block-shaped compound fertilizer raw materials.

[0054] 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 further provided in the present embodiment. Specifically, the mixing unit 6 also includes a guide cylinder 62. Two guide cylinders 62 are arranged on the upper and lower sides of the inner wall of the mixing cylinder 2. The middle part of the guide cylinder 62 is an annular hole 63 sleeved on the outside of the auxiliary shaft 57. The guide cylinder 62 is located above the mixing disk 61. The guide cylinder 62 is fixedly installed on the inner wall of the mixing cylinder 2, and the guide cylinder 62 cooperates with the annular hole 63 to facilitate the guidance of the compound fertilizer raw materials, so that the compound fertilizer raw materials can smoothly fall on the upper end of the mixing disk 61; the number of the mixing disk 61 is two, and the mixing disk 61 is fixedly sleeved on the outer wall of the auxiliary shaft 57. A stirring tooth 64 for stirring and mixing the compound fertilizer raw materials is installed between the mixing disk 61 and the guide cylinder 62, and the stirring teeth 64 between the mixing disk 61 and the guide cylinder 62 are staggered.

[0055] Furthermore, in this embodiment, the guide cylinder 62 is composed of two conical cylinders symmetrically distributed up and down, and the distance between the two conical cylinders of the same guide cylinder 62 gradually decreases toward the side close to the auxiliary shaft 57, so that the side of the upper conical cylinder close to the axis of the auxiliary shaft 57 and the side of the lower conical cylinder away from the axis of the auxiliary shaft 57 are both inclined downward; the side of the mixing disk 61 away from the axis of the auxiliary shaft 57 gradually tilts downward, and the distance between the lower conical cylinder and the mixing disk 61 gradually decreases toward the side away from the axis of the auxiliary shaft 57, and a plurality of annularly distributed drop openings 65 are evenly opened at the outer edge of the mixing disk 61.

[0056] In addition, in order to improve the stirring and mixing efficiency of the compound fertilizer raw materials, in this embodiment, a plurality of heating rods 66 staggered with the stirring teeth 64 are evenly arranged circumferentially between the conical cylinder located at the lower side and the upper end of the mixing disk 61.

[0057] In the specific implementation process, the auxiliary shaft 57 drives the rotary cutter 554 to rotate to crush the block-shaped compound fertilizer raw materials, and the auxiliary shaft 57 drives the mixing disk 61 to rotate synchronously, so that the mixing disk 61 and the guide cylinder 62 rotate relative to each other; when the compound fertilizer raw materials in a crushed state fall downward, they fall to the upper end of the mixing disk 61 under the guidance of the guide cylinder 62, and then the mixing disk 61 cooperates with the guide cylinder 62 to drive the stirring teeth 64 to stir and mix the compound fertilizer raw materials. At the same time, the heating rod 66 is started, and the compound fertilizer raw materials are heated and dried by the heating rod 66, so as to avoid the compound fertilizer raw materials from agglomerating or adhering to the inner wall of the mixing cylinder 2 during the stirring and mixing process and being difficult to clean, so that the compound fertilizer raw materials after stirring and mixing are formed into dry crushed state.

[0058] In addition, the two groups of guide cylinders 62 and mixing disks 61 distributed up and down can enhance the stirring and mixing effect of the compound fertilizer raw materials, thereby mixing them into compound fertilizer. Subsequently, the mixed compound fertilizer falls downward through the drop port 65 and is discharged into the discharge cylinder 4, so that the spiral blades 51 inside the discharge cylinder 4 can transport and discharge the compound fertilizer to the side away from the mixing cylinder 2.

[0059] Embodiment 2: Reference Figure 8 and Fig. 9 As shown, on the basis of the first embodiment, in order to improve the use effect and storage effect of the compound fertilizer, it is necessary to granulate the produced compound fertilizer. Based on this, a corresponding granulation unit 7 is also provided in this embodiment. The granulation unit 7 is specifically as follows: The granulation unit 7 includes a rotating cover 71 rotatably sleeved on the end of the discharge barrel 4 away from the mixing barrel 2, and a plurality of annularly distributed discharge ports 41 are evenly arranged on the side of the discharge barrel 4 away from the mixing barrel 2, and a plurality of through holes 72 corresponding to the positions of the discharge ports 41 are opened on the rotating cover 71, and a plurality of connecting grooves 73 arranged alternately with the through holes 72 are opened inside the rotating cover 71.

[0060] Furthermore, in this embodiment, a plurality of extrusion holes 74 are provided on the side of the connecting groove 73 close to the discharge barrel 4, a plurality of particle outlets 75 connected to the connecting groove 73 are provided on the side of the rotating cover 71 away from the discharge barrel 4, a cutting knife 76 is slidably arranged inside the connecting groove 73, a rotating ring 77 is rotatably arranged inside the rotating cover 71, one end of the plurality of cutting knives 76 is commonly connected to the rotating ring 77, and the other end is commonly installed with a gear ring 78 rotatably mounted on the outer wall of the rotating cover 71, a forward and reverse motor 79 is arranged on the outer wall of the rotating cover 71 through a motor frame, and an output shaft sleeve of the forward and reverse motor 79 is provided with a gear 70 meshing with the gear ring 78.

[0061] 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 barrel 4. At this time, the compound fertilizer is discharged normally from the discharge barrel 4, and the discharged compound fertilizer is in a crushed state for direct use.

[0062] In addition, the rotating cover 71 continues to rotate so that the connecting groove 73 and the particle outlet 75 are connected to the discharge port 41 of the discharge barrel 4. At this time, the forward and reverse motors 79 are started, and the forward and reverse motors 79 drive the ring gear 78 to rotate alternately in forward and reverse directions through the gear 70, so that the ring gear 78 drives the cutting knife 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 pass through the extrusion hole 74 and be extruded into thin strips. At this time, the cutting knife 76 can cut the extruded compound fertilizer into particles of a specified length, thereby realizing the granulation of the compound fertilizer, which is convenient for the storage and transportation of the compound fertilizer.

[0063] In summary, by rotating the rotary cover 71 to adjust the through hole 72 and the particle outlet 75 to be connected to the discharge port 41 respectively, the discharge form of the compound fertilizer can be changed to facilitate adaptive adjustment according to actual production needs, thereby improving adaptability.

[0064] It should be noted that a damping ring (not shown in the figure) is provided between the rotating cover 71 and the discharge barrel 4, and the damping ring can be used to limit the rotating cover 71 accordingly to prevent the rotating cover 71 from rotating randomly after the rotation adjustment and affecting the alignment between the through hole 72 or the particle outlet 75 and the discharge port 41.

[0065] During operation: First step: start the positioning motor 59, and the positioning motor 59 drives the spiral blades 51 on the outer wall to rotate through the rotating shaft 52.

[0066] Step 2: Pour the fermented compound fertilizer raw materials and chemical fertilizers, humic acid, amino acids or beneficial microorganisms into the feeding barrel 3 through the feeding barrel 31 in a specified proportion, and transport the compound fertilizer raw materials to the mixing barrel 2 through the spiral blades 51.

[0067] Step 3: 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 drum 2, an extrusion force can be applied to the compound fertilizer raw materials, so as to facilitate the extrusion and dehydration of the compound fertilizer raw materials during the conveying process, so that the squeezed water flows downward through the filter screen 542 to the water receiving drum 543, thereby effectively removing excess water in the compound fertilizer raw materials, thereby ensuring the overall quality of the finished compound fertilizer and preventing the water from affecting the use effect of the compound fertilizer; after the water in the water receiving drum 543 is filled, it can be removed and the water can be poured out.

[0068] Step 4: After being squeezed and dehydrated, the compound fertilizer raw materials fall downward and accumulate on the upper end of the receiving plate 551. During the rotation of the rotating shaft 52, the transmission bevel gear 56 cooperates with the linkage bevel gear 58 to drive the auxiliary shaft 57 to rotate synchronously. The auxiliary shaft 57 drives the rotary cutter 554 to rotate synchronously through the sleeve 553, so that the block compound fertilizer raw materials accumulated on the upper end of the receiving plate 551 can be broken into pieces by the rotary cutter 554, so that the compound fertilizer raw materials in the form of pieces fall into the mixing barrel 2 through the feeding hole 552 to be stirred and mixed, so as to ensure the mixing uniformity of the compound fertilizer raw materials in the form of pieces, and prevent the compound fertilizer raw materials from being unevenly mixed and affecting the use effect.

[0069] Step 5: During the rotation of the auxiliary shaft 57, the mixing disk 61 is driven to rotate synchronously, so that the mixing disk 61 and the guide cylinder 62 rotate relative to each other; when the compound fertilizer raw materials in the form of powder fall downward, they fall to the upper end of the mixing disk 61 under the guidance of the guide cylinder 62, and then the mixing disk 61 cooperates with the guide cylinder 62 to drive the stirring teeth 64 to stir and mix the compound fertilizer raw materials. At the same time, the heating rod 66 is started to heat and dry the compound fertilizer raw materials by the heating rod 66, so as to avoid the compound fertilizer raw materials from agglomerating or adhering to the inner wall of the mixing cylinder 2 during the stirring and mixing process and being difficult to clean, so that the compound fertilizer raw materials after stirring and mixing are formed into dry powder.

[0070] In addition, the two groups of guide cylinders 62 and mixing disks 61 distributed up and down can enhance the stirring and mixing effect of the compound fertilizer raw materials, thereby mixing them into compound fertilizer. Subsequently, the mixed compound fertilizer falls downward through the drop port 65 and is discharged into the discharge cylinder 4, so that the spiral blades 51 inside the discharge cylinder 4 can transport and discharge the compound fertilizer to the side away from the mixing cylinder 2.

[0071] Step 6: When the auxiliary shaft 57 rotates, the transmission bevel gear 56 and the linkage bevel gear 58 cooperate to drive the linkage shaft 53 and the spiral blades 51 on the outer wall thereof to rotate simultaneously, so as to discharge the compound fertilizer in the discharging barrel 4.

[0072] In addition, the spiral blades 51 on the outer walls of the rotating shaft 52 and the linkage shaft 53 rotate in opposite directions, so that when the spiral blades 51 inside the feed barrel 3 rotate to transport the compound fertilizer raw materials to the side close to the mixing barrel 2, the spiral blades 51 inside the discharge barrel 4 transport the mixed compound fertilizer to the side away from the mixing barrel 2 and discharge it through the discharge port 41, thereby realizing simultaneous feeding and discharging of the compound fertilizer raw materials through the upper and lower spiral blades 51 with opposite rotation directions, thereby facilitating the uninterrupted and continuous production of the compound fertilizer raw materials in cooperation with the stirring and mixing unit 6, thereby improving production efficiency.

[0073] Step 7: When the through hole 72 is adjusted to be connected to the discharge port 41 by rotating the rotary cover 71, the compound fertilizer is discharged normally and is in the form of crushed powder after stirring and mixing, so that it can be used directly; when the rotary cover 71 is rotated to adjust the particle outlet 75 to be connected to the discharge port 41, the compound fertilizer will pass through the extrusion hole 74 during the discharge process and be extruded into thin strips.

[0074] At this time, the forward and reverse motor 79 is started, and the forward and reverse motor 79 drives the ring gear 78 to rotate alternately in forward and reverse directions through the gear 70, so that the ring gear 78 drives the cutting knife 76 to swing back and forth in the connecting groove 73, and the thin strip compound fertilizer passing through the extrusion hole 74 can be cut into particles of a specified length by the cutting knife 76, so that the granulation of the compound fertilizer can be realized, so as to facilitate the storage and transportation of the compound fertilizer; thereby, the discharge form of the compound fertilizer can be changed, so as to facilitate adaptive adjustment according to actual production needs, thereby improving adaptability.
