Description

Technical Field

[0001] This application relates to the technical field of fertilizer production, and in particular to a high-efficiency homogenizing device for producing stable compound fertilizer powder. Background Technology

[0002] Stable compound fertilizers are an important component of modern agriculture, improving soil and promoting plant growth through the metabolic activities of microorganisms. Their main components include nitrogen-fixing bacteria, phosphate-solubilizing bacteria, lactic acid bacteria, mycorrhizal fungi, actinomycetes, and their metabolites. These components enhance soil fertility and plant health through various mechanisms. The production process of microbial fertilizers includes raw material preparation, microbial culture, strain screening and quality testing, mixing and preparation, processing, packaging and storage, and finally, quality testing to ensure the product's effectiveness and activity.

[0003] For example, Chinese patent document CN220919068U discloses a fertilizer mixer, including a housing. A motor is located at the center of the upper end of the housing. The output end of the motor extends into the interior of the housing and is fixedly connected to a stirring shaft. A stirring paddle is located at the lower end of the stirring shaft. A discharge pipe is located at the lower end of the housing, and a valve is installed on the discharge pipe. Multiple feeding cylinders are arranged in a circular array at the upper end of the housing, with their center points as the center. The lower ends of the feeding cylinders extend into the housing. An inner cylinder is slidably connected to the lower end of the feeding cylinder. A limit plate is provided at the lower end of the inner cylinder. An installation hole is provided in the middle of the limit plate. A screen for fertilizer granules to fall is installed inside the installation hole. Two first circular protrusions are symmetrically arranged on the lower surface of the limit plate. A telescopic device is provided between the limit plate and the inner top wall of the housing. Through the coordinated arrangement of the feeding cylinder, inner cylinder, limiting plate, screen, telescopic device, first circular protrusion, driving component and second circular protrusion, the motor will drive the stirring paddle and driving component to rotate through the stirring shaft. The second circular protrusion on the driving component will intermittently contact the first circular protrusion, causing the limiting plate to rise. Then, under the restoring action of the telescopic device, it will fall down, and the stirring paddle will stir and mix the fertilizer falling into the box.

[0004] In the aforementioned related technologies, when producing powdered compound fertilizer containing multiple nutrients, the powder in the tank is slowly mixed by a stirring paddle. During mixing, due to the poor fluidity of the powder and the small cross-section of the lower part of the mixing tank, the powder in the middle part is not easy to be mixed evenly; the powder at the bottom and the middle bottom is more likely to clump or not mix, so the mixing time needs to be increased to make the powder mix more thoroughly. Summary of the Invention

[0005] This application provides a high-efficiency homogenizing device for powder production of stable compound fertilizers, aiming to solve the problem of low powder mixing efficiency in related technologies.

[0006] The technical solution provided in this application for a high-efficiency homogenizing device for producing stable compound fertilizer powder is as follows: A high-efficiency homogenizing device for producing stable compound fertilizer powder includes a mounting frame and a mixing chamber mounted on the mounting frame. The mixing chamber is equipped with a mixing component for stirring the compound fertilizer. The mixing component includes a mixing shaft rotatably connected to the mixing chamber, mixing blades fixed to the mixing shaft, and a mixing motor fixed to the mixing chamber. A pushing component is mounted on the mixing shaft, which includes a pushing ring slidably mounted on the mixing shaft and a mounting sleeve fixed to the pushing ring. A control component is mounted on the mixing shaft to drive the mounting sleeve to move up and down.

[0007] By adopting the above technical solution, in the initial state, the pusher ring is located at the bottom of the mixing chamber. After various raw materials are added to the mixing chamber from above, the raw materials inside the mixing chamber reach a certain height. The mixing motor drives the mixing shaft to rotate, and the mixing shaft drives the mixing blades to rotate. During the rotation of the mixing blades, the raw materials inside the mixing chamber are mixed. Under the action of the control component, the pusher ring on the mixing shaft moves upward. The upward-moving pusher ring pushes the raw materials in the middle position upward, and the upward-moving raw materials will be on the upper surface of the original raw materials. At the same time, a certain space will appear below the pusher ring, and then the raw materials at the edge will flow to the bottom of the pusher ring. During the rotation of the mixing blades, the raw materials inside the mixing chamber will be mixed better. Due to the upward pushing of the raw materials, the effect of turning the raw materials inside the mixing chamber upward can be achieved, thereby improving the mixing efficiency in the compound fertilizer production process. Specifically, in the compound fertilizer production process, the mixing efficiency directly affects the product quality and production cost. Traditional mixing processes often suffer from incomplete mixing due to differences in raw material density and uneven particle size, resulting in problems such as stratification or mixing dead zones. To address this industry pain point, the mixing device achieves three-dimensional circulating mixing of raw materials through the synergistic action of the pusher ring and mixing blades. The device combines the vertical upward movement of the bottom pusher ring with the rotation of the three-dimensional mixing blades, which not only overcomes the separation phenomenon caused by gravity settling, but also enhances the interpenetration mixing between particles through the spatial displacement effect. When the mixing motor drives the mixing blades to rotate, the raw materials are simultaneously subjected to three-dimensional forces of radial shear, axial convection and circumferential diffusion, achieving initial dispersion mixing. The raw materials in the middle are directly pushed upward by the pusher ring, forming a vertical column in the mixing box, while the surrounding raw materials collapse towards the center under the action of gravity, forming a ring flow. This spatial displacement effect allows raw materials of different particle sizes to interpenetrate during vertical displacement, solving the problem of mixing dead zones at the bottom of the box that are difficult to reach with traditional mixing.

[0008] Optionally, a connecting sleeve is fixedly installed on the mixing chamber, a positioning ring is provided on the connecting sleeve, and a material feeding component is provided on the positioning ring. During the process of the pushing ring pushing the raw material near the mixing shaft upward, the material feeding component pushes the upward-moving raw material from the center of the mixing chamber to the edge. The material feeding component includes a first arc-shaped rod fixed on the positioning ring and a second arc-shaped rod slidably connected to the first arc-shaped rod. The lower end faces of the first arc-shaped rod and the second arc-shaped rod will abut against the top of the raw material in the mixing chamber. The end of the first arc-shaped rod away from the positioning ring is fixedly connected to the upper end of the mixing blade.

[0009] By adopting the above technical solution, the mixing shaft rotates, driving the mixing blades, which in turn drive the first and second arc rods to rotate. During the rotation of the first and second arc rods, the raw material moving upward in the middle is pushed to both sides, and the raw material on both sides moves downward to the pusher ring. This allows for better mixing of the raw materials during the mixing process.

[0010] Optionally, the first arc-shaped rod is provided with a first material discharge port, and the second arc-shaped rod is provided with a second material discharge port; when the first material discharge port and the second material discharge port are correspondingly set, during the rotation of the first arc-shaped rod and the second arc-shaped rod, a portion of the material in the middle is moved to the edge; when the first material discharge port and the second material discharge port are misaligned, all the material protruding in the middle is moved to the edge, and the rotating disk is provided with an adjustment component for adjusting the position of the second arc-shaped rod.

[0011] By adopting the above technical solution, the control component drives the pusher ring on the mixing shaft to move upward. The upward-moving pusher ring pushes the raw material in the middle position upward, and the upward-moving raw material will be above the original raw material. At the same time, a certain space will appear below the pusher ring, and then the raw material at the edge will flow to the bottom of the pusher ring. During the rotation of the mixing shaft, the mixing blades are driven, and the mixing blades drive the first arc rod and the second arc rod to rotate. During the rotation of the first arc rod and the second arc rod, the upward-moving raw material in the middle part is pushed to both sides. When the adjustment component drives the second arc rod to move, the space between the first discharge port and the second discharge port can be adjusted. The size of the overlapping area is adjusted. When the first and second discharge ports are perfectly aligned, a portion of the material in the middle is moved towards the edge during the rotation of the first and second arc rods. When the first and second discharge ports are misaligned, all the material protruding in the middle is moved towards the edge. Since the overlapping area of ​​the first and second discharge ports can be increased or decreased, the clumps of material entering between the first and second discharge ports can be squeezed during the change in the size of the overlapping area, thereby improving the mixing effect of the materials during the mixing process.

[0012] Optionally, the connecting sleeve is fitted onto the mixing shaft, and the mixing shaft is rotatably connected to the connecting sleeve. A rotating disk is fixedly installed on the connecting sleeve. The adjusting assembly includes multiple adjusting protrusions fixed to the side of the rotating disk and an adjusting spring fixed to the first arc-shaped rod. The end of the adjusting spring away from the rotating disk is fixed to the second arc-shaped rod. The adjusting protrusions are provided with arc-shaped surfaces, and the adjusting spring pushes the end face of the second arc-shaped rod to abut against the arc-shaped surface.

[0013] By adopting the above technical solution, since the position of the rotating disk remains unchanged, the mixing shaft drives the mixing blades to rotate, which in turn drives the first arc-shaped rod to rotate. The second arc-shaped rod is slidably connected to the first arc-shaped rod. During the rotation of the first arc-shaped rod, the second arc-shaped rod will rotate. The end face of the second arc-shaped rod abuts against the arc-shaped surface, and the arc-shaped surface will push the second arc-shaped rod to slide on the first arc-shaped rod. This facilitates the adjustment of the overlapping area of ​​the first and second discharge ports. On the one hand, it facilitates the compression of the clumps of raw materials between the first and second discharge ports. On the other hand, it prevents all the raw materials from being pushed to the edge of the mixing box, so that the rising raw materials are more evenly sprinkled on the top, which facilitates faster mixing of subsequent materials.

[0014] Optionally, the mounting frame is provided with a feeding assembly for adding unmixed fertilizer raw materials into the mixing chamber. The feeding assembly includes a feeding hopper fixed to the mounting frame by bolts and a feeding pipe fixed to the bottom of the feeding hopper. The end of the feeding pipe away from the feeding hopper is inserted into the mixing chamber and communicates with the interior of the mixing chamber.

[0015] By adopting the above technical solution, different raw materials are added to the feeding hopper in sequence during the feeding process. The raw materials in the feeding hopper enter the mixing box through the feeding pipe. Then, the raw materials in the mixing box are mixed by the mixing component. Under the action of the feeding component, the raw materials can be added to the mixing box more effectively.

[0016] Optionally, the control component includes two threaded grooves on the mixing shaft and a threaded block fixed on the mounting sleeve. The two threaded grooves have the same pitch and opposite directions of rotation. The threaded block is inserted into the threaded groove. The mounting sleeve is threadedly connected to the mixing shaft through the threaded block and the threaded groove. A guide rod is fixedly installed on the connecting sleeve, and the pusher ring passes through the guide rod.

[0017] By adopting the above technical solution, since there are two threaded grooves on the mixing shaft, the mixing shaft forms a reciprocating screw. During the rotation of the mixing shaft, the pusher ring can move up and down through the setting of the guide rod, which will push the raw material in the middle position to move upward.

[0018] Optionally, an mounting ring is fixedly installed on the mixing shaft, and the mixing blades include a scraper fixed on the mounting ring and a spiral blade fixed on the scraper. The spiral blades abut against the inner wall of the mixing chamber, and the scraper abuts against the inner wall of the mixing chamber.

[0019] By adopting the above technical solution, since the spiral blades abut against the inner wall of the mixing chamber, and the scraper also abuts against the inner wall of the mixing chamber, during the process of the mixing shaft driving the spiral blades and scraper to rotate, the spiral blades and scraper will both abut against the inner wall of the mixing chamber, thus making it easier to clean the raw materials adhering to the inner wall of the mixing chamber.

[0020] Optionally, the lower surface of the pusher ring is provided with a tapered surface.

[0021] By adopting the above technical solution, since the lower surface of the pusher ring is set as a conical surface, the raw material below will be pushed to move to both sides during the process of the pusher ring moving down. At this time, a space will be dug out below the pusher ring for the pusher ring to move down, thereby facilitating the downward movement of the pusher ring.

[0022] Optionally, the first arc-shaped rod is provided with a plurality of first material leakage ports, which are evenly spaced along the length direction of the first arc-shaped rod, and the second arc-shaped rod is provided with a plurality of second material leakage ports, which are evenly spaced along the length direction of the second arc-shaped rod.

[0023] Optionally, the side of the rotating disk is provided with multiple adjustment protrusions, and the multiple adjustment blocks are evenly spaced along the circumference of the rotating disk, and each adjustment protrusion is provided with an arc-shaped surface.

[0024] By adopting the above technical solution, since multiple adjustment protrusions are set on the rotating disk, the second arc-shaped rod can be moved intermittently and reciprocally under the action of the multiple adjustment protrusions.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. During the rotation of the mixing blades, the raw materials in the mixing chamber are mixed. Then, under the action of the control components, the pusher ring on the mixing shaft moves upward. The upward-moving pusher ring pushes the raw materials in the middle position upward. The upward-moving raw materials will be on the upper surface of the original raw materials. At the same time, a certain space will appear below the pusher ring. Then the raw materials at the edge will flow to the lower part of the pusher ring. During the rotation of the mixing blades, the raw materials in the mixing chamber will be mixed better. Due to the upward pushing of the raw materials, the raw materials in the mixing chamber can be turned up, thereby improving the mixing efficiency in the compound fertilizer production process. 2. The mixing blades drive the first and second arc rods to rotate. During the rotation of the first and second arc rods, the raw material moving upward in the middle part is pushed to both sides, and the raw material on both sides moves downward to the pusher ring. This can improve the mixing effect of the raw materials during the mixing process. 3. When the adjusting component moves the second arc-shaped rod, the overlapping area between the first and second discharge ports can be adjusted. When the first and second discharge ports are perfectly aligned, a portion of the material in the middle is moved towards the edge during the rotation of the first and second arc-shaped rods. When the first and second discharge ports are misaligned, all the material protruding in the middle is moved towards the edge. Since the overlapping area between the first and second discharge ports can be increased or decreased, the clumps of material entering between the first and second discharge ports can be squeezed during the change in the overlapping area, thereby improving the mixing effect of the materials during the mixing process.

Detailed Implementation

[0035] The following combination Figures 1-8 This application will be described in further detail.

[0036] This application discloses a high-efficiency homogenizing device for producing stable compound fertilizer powders. (Refer to...) Figures 1 to 8 A high-efficiency homogenizing device for producing stable compound fertilizer powder includes a mounting frame 01 and a mixing chamber 02 mounted on the mounting frame 01. The mounting frame 01 is equipped with a feeding component 1 for adding unmixed fertilizer raw materials into the mixing chamber 02 and a mixing component 2 for stirring the compound fertilizer in the mixing chamber 02. The mixing component 2 can mix the compound fertilizer in the mixing chamber 02 more evenly.

[0037] In this embodiment, the upper end of the mixing box 02 is set as a cylindrical structure and the lower end is set as a hemispherical structure. A discharge pipe is provided at the bottom of the mixing box 02, and a control valve is installed on the discharge pipe. When the fertilizer mixed in the mixing box 02 needs to be discharged, the control valve is opened, and then the fertilizer in the mixing box 02 is discharged from the discharge pipe under the action of gravity.

[0038] The feeding assembly 1 includes a feeding hopper 11 fixed to the mounting frame 01 by bolts and a feeding pipe 12 fixed to the bottom of the feeding hopper 11. The end of the feeding pipe 12 away from the feeding hopper 11 is inserted into the mixing chamber 02 and communicates with the inside of the mixing chamber 02. Unmixed raw materials are added to the feeding hopper 11 in sequence. Then, the raw materials in the feeding hopper 11 will fall into the mixing chamber 02 through the feeding pipe 12 under the action of gravity. Since different raw materials need to be added to the mixing chamber 02 in sequence, the raw materials in the mixing chamber 02 will exhibit a stratification phenomenon. At this time, the mixing assembly 2 is required to stir the raw materials in the mixing chamber 02.

[0039] To facilitate the installation of the feeding pipe 12, a feeding port is provided on the mixing chamber 02. The feeding pipe 12 is inserted into the feeding port to facilitate the installation of the feeding pipe 12. In addition, in this embodiment, the feeding hopper 11 is configured with a large upper cross-section and a small lower cross-section to facilitate the feeding of all the raw materials in the feeding hopper 11 into the mixing chamber 02 through the feeding pipe 12.

[0040] The mixing assembly 2 includes a mixing shaft 21 rotatably connected to the mixing chamber 02, mixing blades 22 fixed to the mixing shaft 21, and a mixing motor 23 fixed to the mixing chamber 02. The mixing shaft 21 is vertically arranged, and the axis of the mixing shaft 21 coincides with the axis of the mixing chamber 02. The output shaft of the mixing motor 23 is fixedly connected to the mixing shaft 21. The mixing motor 23 drives the mixing shaft 21 to rotate, and the mixing shaft 21 drives the mixing blades 22 to rotate. The mixing blades 22 mix and stir the raw materials in the mixing chamber 02.

[0041] An mounting ring 03 is provided on the mixing shaft 21, and the mixing blade 22 is fixed on the mounting ring 03. The mixing blade 22 includes a scraper 221 fixed on the mounting ring 03 and a spiral blade 222 fixed on the scraper 221. The spiral blade 222 abuts against the inner wall of the mixing box 02. During the rotation of the mixing shaft 21, the spiral blade 222 can push the raw material at the lower edge to move upward. During the upward movement of the raw material at the edge, the raw material in the mixing box 02 will be mixed. Since the lower end of the mixing box 02 is set as a hemispherical structure, the scraper 221 can mix the raw material on the inner wall of the mixing box 02, reducing the raw material from sticking to the inner wall of the mixing box 02. Since the spiral blade 222 also abuts against the inner wall of the mixing box 02, the raw material on the inner wall of the mixing box 02 can also be cleaned by the rotation of the spiral blade 222.

[0042] A pusher assembly 3 is provided on the mixing shaft 21. The pusher assembly 3 includes a pusher ring 31 sleeved on the mixing shaft 21 and a mounting sleeve 32 fixed on the pusher ring 31. The pusher ring 31 slides along the length of the mixing shaft 21, and the mounting sleeve 32 is also sleeved on the mixing shaft 21. By moving the pusher ring 31 upward, the raw materials in the mixing chamber 02 near the mixing shaft 21 can be pushed upward. Then, the raw materials on both sides will move towards the position near the mixing shaft 21 under the action of gravity. At the same time, the spiral blades 222 can convey the raw materials at the edge upward, thereby making the raw materials in the mixing chamber 02 mix faster.

[0043] A control component 4 is provided on the mixing shaft 21. The control component 4 is used to drive the mounting sleeve 32 to move up and down. The control component 4 includes two threaded grooves 41 provided on the mixing shaft 21 and a threaded block (not shown in the figure) fixed on the mounting sleeve 32. The two threaded grooves 41 have the same pitch and opposite directions of rotation. The threaded block is inserted into the threaded grooves 41. The mounting sleeve 32 is threadedly connected to the mixing shaft 21 through the threaded block and the threaded grooves 41. A connecting sleeve 04 is fixedly installed on the mixing housing 02. The connecting sleeve 04 is sleeved on the mixing shaft 21, and the mixing shaft 21 is rotatably connected to the connecting sleeve 04. A rotating disk 5 is fixedly installed, and a guide rod 51 is fixedly installed on the rotating disk 5. The guide rod 51 is set along the length direction of the mixing shaft 21. The pusher ring 31 passes through the guide rod 51 and is slidably connected to the guide rod 51. During the process of the mixing motor 23 driving the mixing shaft 21 to rotate, the mounting ring 03 drives the scraper 221 to rotate, and the scraper 221 drives the spiral blade 222 to rotate, and then the raw material at the edge of the mixing box 02 is conveyed upward. During the rotation of the mixing shaft 21, under the action of the guide rod 51, the two threaded grooves 41 and the threaded block, the pusher ring 31 will move up and down.

[0044] In this embodiment, when the threaded block moves to the top of the threaded groove 41, the threaded block is at the intersection of the two threaded grooves 41. During the continued rotation, the threaded block will move into the reverse threaded groove 41, thereby causing the threaded block to drive the pusher ring 31 to move down. Since the threaded block and the two oppositely arranged threaded grooves 41 are existing technologies, the specific structure and working principle will not be described in detail in this application.

[0045] A conical surface is provided on the lower surface of the pusher ring 31. During the upward movement of the pusher ring 31, it pushes the raw material close to the mixing shaft 21 upward. During the downward movement of the pusher ring 31, the conical surface pushes the raw material below the pusher ring 31 to move to both sides, making room for the downward movement of the pusher ring 31.

[0046] A positioning ring 52 is provided on the connecting sleeve 04, and a material feeding component 6 is provided on the positioning ring 52. During the process of the pushing ring 31 pushing the raw material near the mixing shaft 21 upward, the material feeding component 6 pushes the upward-moving raw material from the center of the mixing box 02 to the edge. At the same time, during the process of the pushing ring 31 pushing the raw material upward, a certain space will appear below the pushing ring 31. At this time, the raw material at the edge will move towards the center. Then, under the action of the material feeding component 6, the mixing effect of the raw material in the mixing box 02 is better.

[0047] The feeding assembly 6 includes a first arc-shaped rod 61 fixed on the positioning ring 52 and a second arc-shaped rod 62 slidably connected to the first arc-shaped rod 61. The lower end faces of the first arc-shaped rod 61 and the second arc-shaped rod 62 will abut against the top of the raw material in the mixing box 02. During the rotation of the first arc-shaped rod 61 driven by the positioning ring 52, the second arc-shaped rod 62 will rotate simultaneously with the first arc-shaped rod 61, and the pushing ring 31 will push the raw material upward. The first arc-shaped rod 61 and the second arc-shaped rod 62 will push the upward-moving raw material in the middle to move to both sides.

[0048] In this embodiment, the end of the first arc-shaped rod 61 away from the positioning ring 52 is fixedly connected to the upper end of the spiral blade 222. The lower end of the spiral blade 222 is fixed to the mounting ring 03 with the scraper 221, and the upper end is fixed to the positioning ring 52 by the first arc-shaped rod 61. Then, it will be more stable when the mixing shaft 21 drives the spiral blade 222 to rotate.

[0049] Multiple first material discharge ports 7 are provided on the first arc-shaped rod 61, and the multiple first material discharge ports 7 are evenly spaced along the length direction of the first arc-shaped rod 61. Multiple second material discharge ports 71 are provided on the second arc-shaped rod 62, and the multiple second material discharge ports 71 are evenly spaced along the length direction of the second arc-shaped rod 62. The first material discharge ports 7 and the second material discharge ports 71 are correspondingly arranged. Since the first arc-shaped rod 61 slides on the first arc-shaped rod 61, the positions of the first material discharge ports 7 and the second material discharge ports 71 can be adjusted by adjusting the position of the second arc-shaped rod 62. During the rotation of the first arc-shaped rod 61 and the second arc-shaped rod 62, when the first material discharge ports 7 and the second material discharge ports 71 are completely aligned, a portion of the material in the middle can be moved to the edge. When the first material discharge ports 7 and the second material discharge ports 71 are misaligned, all the material protruding in the middle can be moved to the edge, at which time there will be more material at the edge.

[0050] During the reciprocating movement of the second arc rod 62, the overlapping area of ​​the first discharge port 7 and the second discharge port 71 will change from small to large and then from large to small. During the rotation of the first arc rod 61 and the second arc rod 62, the clumps of material between the first discharge port 7 and the second discharge port 71 will be squeezed, thereby reducing the clumps of material in the mixing box 02 and accelerating the subsequent mixing of raw materials.

[0051] An adjustment assembly 8 is provided on the rotating disk 5. The adjustment assembly 8 is used to adjust the position of the second arc-shaped rod 62. The adjustment assembly 8 includes multiple adjustment protrusions 81 fixed on the side of the rotating disk 5 and an adjustment spring 82 fixed on the first arc-shaped rod 61. The end of the adjustment spring 82 away from the rotating disk 5 is fixed on the second arc-shaped rod 62. An arc-shaped surface 83 is provided on the adjustment protrusion 81. Under the action of the arc-shaped surface 83, the distance between one end of the adjustment protrusion 81 and the axis of the rotating disk 5 is less than the distance between the other end and the axis of the rotating disk 5.

[0052] Under the action of the adjusting spring 82, the end face of the second arc-shaped rod 62 abuts against the side of the rotating disk 5. Then, as the mixing shaft 21 drives the spiral blade 222 to rotate, the spiral blade 222 drives the first arc-shaped rod 61 and the second arc-shaped rod 62 to rotate simultaneously. The end face of the second arc-shaped rod 62 abuts against the arc surface 83. Since the arc surface 83 is inclined, the area corresponding to the first discharge port 7 and the second discharge port 71 can gradually increase, and the adjusting spring 82 is gradually stretched. After the end face of the second arc-shaped rod 62 is separated from the arc surface 83, under the action of the adjusting spring 82, the second arc-shaped rod 62 is pulled back to its original position, and the first discharge port 7 and the second discharge port 71 are misaligned. At this time, the first discharge port 7 and the second discharge port 71 no longer correspond.

[0053] Because the rotating disk 5 has multiple adjustment protrusions 81 on its side, and each adjustment protrusion 81 has an arc-shaped surface 83, the second arc-shaped rod 62 can be moved back and forth during the mixing process, so that the upward-moving raw materials are evenly distributed on the surface of the material above, reducing the accumulation of raw materials at the edge of the mixing box 02, and thus making the mixing process more efficient.

[0054] The implementation principle of the high-efficiency homogenizing equipment for producing stable compound fertilizer powder in this application embodiment is as follows: During the production of powdered fertilizer, various powdered raw materials are sequentially fed into the mixing chamber 02 through the feeding pipe 12 via the feeding hopper 11. After all raw materials are added into the mixing chamber 02, the mixing motor 23 is turned on. During the operation of the mixing motor 23, the mixing shaft 21 will rotate. In the initial state, the pusher ring 31 is at the bottom. Under the action of the threaded block, the threaded groove 41 and the guide rod 51, the pusher ring 31 pushes the raw material in the center. As the mixing shaft 21 moves upward, it drives the spiral blades 222 to rotate. The spiral blades 222 push the raw materials at the edge upward, and the spiral blades 222 drive the first arc rod 61 and the second arc rod 62 to rotate. During the rotation of the first arc rod 61 and the second arc rod 62, the raw materials moving upward in the middle are pushed, causing the material moving upward in the center to move towards the edge of the mixing box 02. The material at the edge will fall below the pusher ring 31. By flipping the raw materials up and down, the raw materials can be mixed more quickly, thereby improving the mixing efficiency of the raw materials.

[0055] During the rotation of the helical blades 222 driven by the mixing shaft 21, the helical blades 222 drive the first arc-shaped rod 61 and the second arc-shaped rod 62 to rotate simultaneously. The end face of the second arc-shaped rod 62 abuts against the arc-shaped surface 83. Due to the inclined setting of the arc-shaped surface 83, the area corresponding to the first discharge port 7 and the second discharge port 71 gradually increases, and the adjusting spring 82 is gradually stretched. After the end face of the second arc-shaped rod 62 disengages from the arc-shaped surface 83, the second arc-shaped rod 62 is pulled back to its original position under the action of the adjusting spring 82, and the first discharge port 7 and the second discharge port 71 are misaligned. At this time, the first discharge port 7 and the second discharge port 71 no longer correspond. Since multiple adjusting protrusions 81 are provided on the side of the rotating disk 5, and each adjusting protrusion 81 is provided with an arc-shaped surface 83, the second arc-shaped rod 62 can move back and forth during the mixing of fertilizer, so that the upward-moving raw materials are evenly distributed on the surface of the upper material, reducing the accumulation of raw materials at the edge of the mixing box 02, and thus increasing the efficiency during the mixing process.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
