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

[0002] The stable compound fertilizer is an important part of modern agriculture, and the soil is improved and the plant growth is promoted through the metabolic activity of microorganisms. The main components include nitrogen-fixing bacteria, phosphorus-dissolving bacteria, lactic acid bacteria, mycorrhizal fungi, actinomycetes and their metabolites, which improve soil fertility and plant health through different mechanisms. The production process of the microbial fertilizer includes raw material preparation, microbial culture, strain screening and quality detection, mixing and preparation, processing, packaging and storage, and finally quality detection to ensure the effect and activity of the product.

[0003] For example, the Chinese patent document with the publication number CN220919068U discloses a fertilizer mixing machine, which comprises a box body, a motor is arranged at the upper end center of the box body, the output end of the motor extends into the interior of the box body and is fixedly connected with a stirring shaft, the lower end of the stirring shaft is provided with a stirring paddle, the lower end of the box body is provided with a discharge pipe, the discharge pipe is provided with a valve, the upper end of the box body is annularly arranged with a plurality of discharge cylinders with the center point as the center, the lower end of the discharge cylinder extends into the box body, the lower end of the discharge cylinder is slidably connected with an inner cylinder, the lower end of the inner cylinder is provided with a limiting plate, the middle part of the limiting plate is provided with a mounting hole, the interior of the mounting hole is mounted with a screen for falling of fertilizer particles, the lower surface of the limiting plate is symmetrically provided with two first circular protrusions, and the limiting plate and the inner top wall of the box body are provided with a telescopic device. Through the cooperation of the discharge cylinder, the inner cylinder, the limiting plate, the screen, the telescopic device, the first circular protrusion, the driving member and the second circular protrusion, the motor works to drive the stirring paddle and the driving member to rotate, the second circular protrusion on the driving member is in turn intermittently in contact with the first circular protrusion to make the limiting plate rise, and then the limiting plate falls under the restoring action of the telescopic device, and the stirring paddle stirs and mixes the fertilizer falling into the box body.

[0004] In the related technology, when producing the powder compound fertilizer containing multiple nutrients, the powder in the box body is slowly mixed by the stirring paddle. During the mixing, due to the poor flowability of the powder and the small lower section of the mixing tank, the powder in the middle part is not easy to be stirred uniformly, and the powder at the bottom and the middle bottom is more likely to form clumps or not to be mixed, so that the mixing time needs to be improved to make the powder more fully mixed.

DETAILED DESCRIPTION

[0039] The following Figures 1-8 The application is further described in detail.

[0040] The embodiment of the application discloses a stable compound fertilizer production powder efficient homogenizing equipment. Figures 1 to 8 A stable compound fertilizer production powder efficient homogenizing equipment includes a mounting frame 01 and a mixing box 02 arranged on the mounting frame 01, the mounting frame 01 is provided with a feeding assembly 1 for adding un-mixed fertilizer raw materials into the mixing box 02 and a mixing assembly 2 for stirring the compound fertilizer in the mixing box 02, and the mixing assembly 2 can mix the compound fertilizer in the mixing box 02 more uniformly.

[0041] In the embodiment, the upper end of the mixing box 02 is provided in a cylindrical structure, the lower end is provided in a semi-spherical structure, and a discharge pipe is arranged at the bottom of the mixing box 02, and a control valve is arranged on the discharge pipe; when the mixed fertilizer 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.

[0042] The feeding assembly 1 includes a feeding hopper 11 fixed on the mounting frame 01 by bolts and a feeding pipe 12 fixed at 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 box 02 and communicates with the inside of the mixing box 02, the un-mixed raw materials are sequentially added into the feeding hopper 11, and then the raw materials in the feeding hopper 11 fall into the mixing box 02 through the feeding pipe 12 under the action of gravity; since different raw materials need to be sequentially added into the mixing box 02, the raw materials in the mixing box 02 will appear to be layered, and at this time, the mixing assembly 2 needs to stir the raw materials in the mixing box 02.

[0043] In order to facilitate the installation of the feeding pipe 12, the mixing box 02 is provided with a feeding port, and the feeding pipe 12 is inserted into the feeding port, so as to facilitate the installation of the feeding pipe 12. In addition, in the embodiment, the feeding hopper 11 is provided with a large upper end cross section and a small lower end cross section, so as to facilitate the feeding of the raw materials in the feeding hopper 11 into the mixing box 02 through the feeding pipe 12.

[0044] The mixing assembly 2 comprises a mixing shaft 21 rotatably connected to the mixing box 02, mixing blades 22 fixed to the mixing shaft 21, and a mixing motor 23 fixed to the mixing box 02. The mixing shaft 21 is vertically arranged, and the axis of the mixing shaft 21 coincides with the axis of the mixing box 02. The output shaft of the mixing motor 23 is fixedly connected to the mixing shaft 21. The mixing shaft 21 is driven to rotate by the mixing motor 23, and the mixing blades 22 are driven to rotate by the mixing shaft 21. The mixing blades 22 mix and stir the raw materials in the mixing box 02.

[0045] The mixing shaft 21 is provided with a mounting ring 03, and the mixing blades 22 are fixed to the mounting ring 03. The mixing blades 22 comprise a scraper 221 fixed to the mounting ring 03 and a spiral blade 222 fixed to the scraper 221. The spiral blade 222 abuts against the inner wall of the mixing box 02. Then, during the rotation of the mixing shaft 21, the spiral blade 222 can push the raw materials at the lower edge to move upward. During the movement of the raw materials at the edge to the upper side, the raw materials in the mixing box 02 are mixed. Since the lower end of the mixing box 02 is provided with a hemispherical structure, the scraper 221 can mix the raw materials on the inner wall of the mixing box 02, reducing the adhesion of the raw materials 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 materials on the inner wall of the mixing box 02 can also be cleaned by the rotation of the spiral blade 222.

[0046] The mixing shaft 21 is provided with a pushing assembly 3. The pushing assembly 3 comprises a pushing ring 31 sleeved on the mixing shaft 21 and a mounting sleeve 32 fixed to the pushing ring 31. The pushing ring 31 slides along the length direction of the mixing shaft 21, and the mounting sleeve 32 is also sleeved on the mixing shaft 21. By moving the pushing ring 31 upward, the raw materials in the mixing box 02 close to the mixing shaft 21 can be pushed to move upward. Then, the raw materials on both sides move to the position close to the mixing shaft 21 under the action of gravity. At the same time, the spiral blade 222 can transport the raw materials at the edge upward, so that the mixing speed of the raw materials in the mixing box 02 is faster.

[0047] The control assembly 4 is arranged on the mixing shaft 21 and used to drive the mounting sleeve 32 to move up and down. The control assembly 4 comprises two screw grooves 41 arranged on the mixing shaft 21 and a screw block (not shown in the figure) fixed on the mounting sleeve 32. The two screw grooves 41 have the same pitch and opposite rotation directions. The screw block is inserted into the screw grooves 41. The mounting sleeve 32 is threadedly connected with the mixing shaft 21 through the screw block and the screw grooves 41. A connecting sleeve 04 is fixedly arranged on the mixing box 02. The connecting sleeve 04 is sleeved on the mixing shaft 21 and is rotationally connected with the mixing shaft 21. A rotating disc 5 is fixedly arranged on the connecting sleeve 04. A guide rod 51 is fixedly arranged on the rotating disc 5 and extends along the length direction of the mixing shaft 21. The pushing ring 31 is sleeved on the guide rod 51 and is slidably connected with the guide rod 51. During the rotation of the mixing shaft 21 driven by the mixing motor 23, the mounting ring 03 drives the scraper 221 to rotate, and the scraper 221 drives the spiral blade 222 to rotate, so as to convey the raw materials at the edge of the mixing box 02 upwards. During the rotation of the mixing shaft 21, the pushing ring 31 is driven to move up and down by the guide rod 51, the two screw grooves 41 and the screw block.

[0048] In the embodiment, when the screw block moves to the uppermost position of the screw grooves 41, the screw block is located at the intersection of the two screw grooves 41. During the continuous rotation, the screw block moves into the opposite screw groove 41, so that the screw block drives the pushing ring 31 to move downwards. Since the screw block and the two oppositely arranged screw grooves 41 belong to the prior art, the specific structure and working principle are not described in detail.

[0049] A conical surface is arranged on the lower surface of the pushing ring 31. During the upward movement of the pushing ring 31, the conical surface pushes the raw materials close to the mixing shaft 21 to move upwards. During the downward movement of the pushing ring 31, the conical surface pushes the raw materials below the pushing ring 31 to move to both sides, so as to provide space for the downward movement of the pushing ring 31.

[0050] A positioning ring 52 is arranged on the connecting sleeve 04. A pushing assembly 6 is arranged on the positioning ring 52. During the upward movement of the raw materials close to the mixing shaft 21 pushed by the pushing ring 31, the pushing assembly 6 pushes the upwardly moved raw materials to move from the center position of the mixing box 02 to the edge position. At the same time, during the upward movement of the raw materials pushed by the pushing ring 31, a certain space is formed below the pushing ring 31. At this time, the raw materials at the edge position move to the middle. Then, under the action of the pushing assembly 6, the mixing effect of the raw materials in the mixing box 02 is better.

[0051] The material stirring assembly 6 comprises 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 abut against the upper side of the raw materials 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 rotates simultaneously with the first arc-shaped rod 61, and the pushing ring 31 pushes the raw materials upward. The first arc-shaped rod 61 and the second arc-shaped rod 62 push the raw materials in the middle upward to move to both sides.

[0052] In the embodiment, the first arc-shaped rod 61 is fixedly connected to the upper end of the helical blade 222 away from the positioning ring 52. The lower end of the helical blade 222 is fixed on the mounting ring 03, and the upper end is fixed on the positioning ring 52 through the first arc-shaped rod 61, so that the helical blade 222 is more stable during the rotation driven by the mixing shaft 21.

[0053] A plurality of first material leakage openings 7 are arranged on the first arc-shaped rod 61 and evenly spaced along the length direction of the first arc-shaped rod 61. A plurality of second material leakage openings 71 are arranged on the second arc-shaped rod 62 and evenly spaced along the length direction of the second arc-shaped rod 62. The first material leakage openings 7 and the second material leakage openings 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 leakage openings 7 and the second material leakage openings 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 leakage openings 7 and the second material leakage openings 71 are completely correspondingly arranged, the raw materials in the middle can be pushed to move to the edge. When the first material leakage openings 7 and the second material leakage openings 71 are misaligned, all the raw materials protruding in the middle can be pushed to move to the edge, and at this time, there are more raw materials at the edge.

[0054] During the reciprocating movement of the second arc-shaped rod 62, the overlapping area of the first material leakage openings 7 and the second material leakage openings 71 changes from small to large and then from large to small. During the rotation of the first arc-shaped rod 61 and the second arc-shaped rod 62, the clumped materials between the first material leakage openings 7 and the second material leakage openings 71 are extruded, so that the clumped materials in the mixing box 02 can be reduced, and the subsequent raw material mixing can be accelerated.

[0055] The adjusting assembly 8 is arranged on the rotating disc 5 and is used for adjusting the position of the second arc-shaped rod 62. The adjusting assembly 8 comprises a plurality of adjusting protrusions 81 fixed on the side surface of the rotating disc 5 and an adjusting spring 82 fixed on the first arc-shaped rod 61. The end of the adjusting spring 82 away from the rotating disc 5 is fixed on the second arc-shaped rod 62. The adjusting protrusions 81 are provided with arc surfaces 83. Under the action of the arc surfaces 83, the distance between one end of the adjusting protrusions 81 and the axis of the rotating disc 5 is less than the distance between the other end of the adjusting protrusions 81 and the axis of the rotating disc 5.

[0056] Under the action of the adjusting spring 82, the end surface of the second arc-shaped rod 62 abuts against the side surface of the rotating disc 5, and then in the process of rotating the helical blade 222 driven by the mixing shaft 21, the helical blade 222 drives the first arc-shaped rod 61 and the second arc-shaped rod 62 to rotate simultaneously, and the end surface of the second arc-shaped rod 62 abuts against the arc surface 83. Since the arc surface 83 is arranged obliquely, the area corresponding to the first material leakage hole 7 and the second material leakage hole 71 can gradually increase, and the adjusting spring 82 is gradually stretched. After the end surface of the second arc-shaped rod 62 is separated from the arc surface 83, the second arc-shaped rod 62 is pulled back to the original position under the action of the adjusting spring 82. The first material leakage hole 7 and the second material leakage hole 71 are arranged in a staggered manner, and the first material leakage hole 7 and the second material leakage hole 71 no longer correspond to each other.

[0057] Since the side surface of the rotating disc 5 is provided with a plurality of adjusting protrusions 81, and each adjusting protrusion 81 is provided with an arc surface 83, in the process of mixing the fertilizer, the second arc-shaped rod 62 can move back and forth, so that the upwardly moved raw materials are uniformly pushed to the surface of the upper materials, reducing the accumulation of raw materials at the edge of the mixing box 02, and then the efficiency in the mixing process is higher.

[0058] The implementation principle of the stable and efficient powder homogenizing equipment for compound fertilizer production is as follows: in the process of producing powder fertilizer, a plurality of powder raw materials are sequentially fed into the mixing box 02 through the upper feeding pipe 12 by the upper feeding hopper 11. After all the raw materials are added into the mixing box 02, the mixing motor 23 is turned on, and the mixing motor 23 drives the mixing shaft 21 to rotate in the process of working. In the initial state, the pushing ring 31 is at the lowermost position, and under the action of the threaded block, the threaded groove 41 and the guide rod 51, the pushing ring 31 pushes the raw materials at the center to move upward. Since the mixing shaft 21 drives the helical blade 222 to rotate, the helical blade 222 pushes the raw materials at the edge to move upward, and the helical blade 222 drives the first arc-shaped rod 61 and the second arc-shaped rod 62 to rotate. In the process of rotating the first arc-shaped rod 61 and the second arc-shaped rod 62, the raw materials at the center are pushed to move to the edge of the mixing box 02, and the raw materials at the edge fall below the pushing ring 31. Through the upward and downward movement of the raw materials, the raw materials can be mixed faster, and the mixing efficiency of the raw materials is improved.

[0059] In the process of rotating the helical blade 222 driven by the mixing shaft 21, the helical blade 222 drives the first arc-shaped rod 61 and the second arc-shaped rod 62 to rotate simultaneously, and the end surface of the second arc-shaped rod 62 abuts against the arc surface 83. Since the arc surface 83 is arranged obliquely, the area corresponding to the first discharge port 7 and the second discharge port 71 can be gradually increased, and the adjusting spring 82 is gradually stretched. After the end surface of the second arc-shaped rod 62 is separated from the arc surface 83, the second arc-shaped rod 62 is pulled back to the original position under the action of the adjusting spring 82. The first discharge port 7 and the second discharge port 71 are arranged in a staggered manner, so that the first discharge port 7 and the second discharge port 71 do not correspond to each other. Since the side surface of the rotating disc 5 is provided with a plurality of adjusting protrusions 81, and each adjusting protrusion 81 is provided with an arc surface 83, the second arc-shaped rod 62 can move back and forth during the mixing of the fertilizer, so that the upwardly moving raw materials are uniformly pushed to the surface of the upper materials, reducing the accumulation of raw materials at the edge of the mixing box 02, and improving the efficiency during the mixing process.

[0060] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
