Technical Field
[0001] This invention relates to the field of fertilizer production technology, and in particular to a pellet organic fertilizer extrusion granulation device. Background Technology
[0002] Organic fertilizers are rich in various organic matter, nitrogen, phosphorus, potassium nutrients and trace elements. They are important fertilizers for improving soil and enhancing crop quality in agricultural planting. Granular organic fertilizers are easier to store, transport and apply by machinery.
[0003] Currently, traditional granulated organic fertilizer extrusion granulation equipment generally suffers from two major technical defects: first, the raw materials are not mixed evenly before granulation, easily leading to agglomeration and stratification, directly resulting in poor subsequent extrusion granulation formation and inconsistent particle quality; second, after granulation, the fertilizer particles are of mixed sizes, lacking an efficient grading and screening structure, making it impossible to accurately separate qualified and unqualified particles, thus affecting the quality of the finished product. Based on this, this application proposes a granulated organic fertilizer extrusion granulation device. Summary of the Invention

[0016] 2. This invention uses a second motor to drive a sun gear that in turn drives planetary gears. The first stirring rod rotates synchronously, while the second stirring rod achieves both revolution and rotation. Combined with the axially staggered stirring blades, it forms an all-around stirring trajectory without dead angles, which can thoroughly break up agglomerated raw materials, greatly improve the uniformity of raw material mixing, provide stable and high-quality raw materials for subsequent extrusion granulation, and effectively ensure the granulation effect. It integrates pretreatment, extrusion granulation, multi-stage screening, and automatic flow guidance and collection functions into one unit.

[0021] This embodiment provides a pelletizing device for organic fertilizer extrusion, such as... Figures 1-2 As shown, the device includes a workbench 1, with an extruder 2 fixedly mounted above it. The extruder 2 is a conventional technology and includes a motor, an extrusion cylinder, and an extrusion rod. The motor is located outside the extrusion cylinder, and its output shaft passes through the inner wall of the extrusion cylinder and is fixedly connected to the extrusion rod. The extrusion rod is rotatably mounted inside the extrusion cylinder, and the motor drives the extrusion rod to rotate. A discharge plate 21 is fixedly mounted at one end of the extruder 2, and a cutter 22 is mounted on one side of the discharge plate 21. The cutter 22 is fixedly connected to the extrusion rod. While the motor drives the extrusion rod to rotate, it also drives the cutter 22 to rotate, cutting the extruded organic fertilizer strips into granules. This avoids problems such as excessively long strips sticking together, delayed granulation leading to inconsistent particle size, and excessive broken material. The formed granules are regular and full with strong particle size consistency, effectively improving the qualification rate of organic fertilizer products. A screening component 3 is installed on one side of the lower part of the workbench 1, and a storage hopper 4 is installed on one side of the screening component 3. A guide plate 5 is fixedly installed between the screening component 3 and the storage hopper 4. The guide plate 5 is inclined towards the side closer to the storage hopper 4, and both the guide plate 5 and the storage hopper 4 are fixedly connected to the inner wall of the workbench 1 to guide and collect the particles after screening, avoid material loss caused by particle splashing and scattering, and ensure material recovery rate. A pretreatment component 6 is also fixedly installed above the workbench 1. The pretreatment component 6 is connected to the extruder 2 and can fully stir and disperse the organic fertilizer raw materials for pretreatment, break up the raw material agglomeration, and ensure the molding effect and particle uniformity of subsequent extrusion granulation.
[0022] like Figures 3-4As shown, the screening assembly 3 includes a frame 31 and a support plate 32. A first motor 33 is fixedly connected to the upper surface of the support plate 32. The output shaft of the first motor 33 passes through the support plate 32 and is fixedly connected to the upper surface of the frame 31, driving the frame 31 to rotate as a whole to cooperate with the screening operation. A first driving component 34 for driving the frame 31 and the support plate 32 to reciprocate is installed on the inner top wall of the frame 31. Multi-layer screening frames 35 are movably connected to both sides of the frame 31. Screening hoppers 36 are fixedly installed inside the screening frames 35. Two sets of second driving components 37 for driving the screening frames 35 to tilt are installed inside the frame 31. The first driving component 34 drives the frame 31 to reciprocate, thereby driving the screening frames 35 and the screening hoppers 36 to reciprocate, enhancing the material screening flowability, avoiding screen hole clogging, and greatly improving screening efficiency and sorting accuracy.
[0023] In one embodiment, the screening hopper 36 has an open end and is composed of a bottom plate 361 and a side plate 362. The side plate 362 is fixedly arranged around the top of the bottom plate 361. The bottom plates 361 of different layers have screen holes of different diameters, and the screen hole diameters of the bottom plates 361 decrease from top to bottom, so as to realize the stratified screening of particles of different sizes. The bottom plate 361 of the bottommost set of screening hoppers 36 is a solid plate, which is used to receive the screened particles.
[0024] When the extruder 2 extrudes fertilizer granules into the screening hopper 36, the first drive unit 34 is activated, driving the frame 31 to reciprocate, so that the fertilizer granules in the screening hopper 36 are better screened. The fertilizer granules fall down layer by layer to the last layer of the screening hopper 36. Then the first motor 33 is rotated to drive the frame 31 to rotate, thereby rotating the screening hopper 36 filled with fertilizer granules to one side of the storage hopper 4. The second drive unit 37 is activated, thereby driving the screening hopper 36 to tilt downward. Then the fertilizer granules fall into the storage hopper 4 along the guide plate 5. Then the storage hopper 4 is taken out.
[0025] In one embodiment, the first driving component 34 specifically includes a fixed frame 341, a reciprocating motor 342, and a connecting plate 343. The fixed frame 341 is fixedly installed on the lower surface of the top of the workbench 1. The reciprocating motor 342 is fixedly installed at the end of the fixed frame 341 away from the storage hopper 4. The output end of the reciprocating motor 342 is fixedly connected to the connecting plate 343. The connecting plate 343 is vertically fixedly installed on the support plate 32. Slider blocks 344 are fixedly installed on both sides of the support plate 32. A slide rail 345 adapted to the slider 344 is also fixedly installed on the top wall of the workbench 1. The slider 344 is slidably installed in the slide rail 345 and driven by the reciprocating motor 342.
[0026] Specifically, by starting the reciprocating motor 342, the entire frame 31 is driven to move back and forth because the connecting plate is fixedly connected to the support plate 32. At this time, the slider 344 slides in the slide rail 345 to ensure the stability of the frame 31 and prevent the frame from tipping over during the screening process.
[0027] Furthermore, the frame 31 is composed of two vertical plates 311, a circular plate 312, a top plate 313, and a bottom plate 314. The vertical plates 311 are fixedly installed on both sides of the top plate 313, the circular plate 312 is fixedly connected to the top of the top plate 313, and the bottom plate 314 is fixedly installed at the bottom of the two vertical plates 311. A fixing rod 315 is provided at the bottom of the bottom plate 314, and a sliding groove 11 is provided at the bottom of the worktable 1. The fixing rod 315 is slidably installed in the sliding groove 11, which further improves the stability of the reciprocating motion of the frame 31. Screening frames 35 are hinged to both sides of the vertical plate 311. Each screening frame 35 includes at least two parallel connecting rods 351. A vertical rod 352 is hinged to the side of the parallel connecting rod 351 away from the vertical plate 311. The parallel connecting rods 351, the vertical rod 352, and the vertical plate 311 together form a parallelogram kinematic pair. Screening hoppers 36 are fixedly connected between the parallel connecting rods 351 at the same horizontal height. A plurality of first mounting holes 353 are evenly arranged on both sides of the vertical plate 311, and a plurality of second mounting holes 353 are evenly arranged on the support plate 32. 21. One end of the parallel connecting rod 351 is fixedly connected to the first mounting hole 353 through a hinge seat, and the other end of the parallel connecting rod 351 is fixedly connected to the second mounting hole 321 through a hinge seat. The installation height and angle of the parallel connecting rod 351 can be adjusted according to production needs, and the connection position between the parallel connecting rod 351 and the vertical rod 352 can be adjusted. Since the first mounting hole 353 and the second mounting hole 321 are provided, multiple sets of parallel connecting rods 351 can be added, thereby allowing multiple sets of screening hoppers 36 to be installed.
[0028] In one embodiment, the two sets of second driving components 37 are staggered to avoid mutual interference. Each second driving component 37 includes a first fixed frame 371, a first hydraulic cylinder 372, a second fixed frame 373, and a second hydraulic cylinder 374. One end of the first fixed frame 371 is fixedly connected to a parallel connecting rod 351 located on one side of the vertical plate 311, and the other end of the first fixed frame 371 is hinged to the output end of the first hydraulic cylinder 372. The end of the first hydraulic cylinder 372 away from the first fixed frame 371 is fixedly connected to the top plate 313. One end of the second fixed frame 373 is fixedly connected to the parallel connecting rod 351 located on the other side of the vertical plate 311, and the other end of the second fixed frame 373 is hinged to the output end of the second hydraulic cylinder 374. The end of the second hydraulic cylinder 374 away from the second fixed frame 373 is fixedly connected to the top plate 313. The tilting angle of the screening hopper 36 is adjusted by the extension and retraction of the first hydraulic cylinder 372 and the second hydraulic cylinder 374, which drives the parallel connecting rod 351 to swing.
[0029] like Figures 5-7As shown, the pretreatment component 6 includes a barrel 61 and a top cover 62. The top cover 62 is fixedly installed on the top of the barrel 61. A feed inlet 66 is provided on one side of the barrel 61. A conveying pipe 63 connected to the extruder 2 is fixedly installed at the bottom of the barrel 61. A regulating valve is provided on one side of the conveying pipe 63. Several stirring rod groups 64 are rotatably installed inside the barrel 61. The stirring rod group 64 includes a first stirring rod 641 and a second stirring rod 642. A driving member 65 is provided above the first stirring rod 641 and the second stirring rod 642 for driving the first stirring rod 641 and the second stirring rod 642 to rotate around the inside of the barrel 61.
[0030] The driving component 65 specifically includes: a second motor 651 fixedly installed on the top of the top cover 62; the output shaft of the second motor 651 passes through the top cover 62 and is fixedly connected to the sun gear 652; the output shaft of the second motor 651 extends into the material cylinder 61 and is fixedly connected to the first stirring rod 641; a connecting rod bracket 653 is also fixedly connected to the output shaft of the second motor 651; the connecting rod bracket 653 has three protruding ends, and the protruding ends have connecting holes; the second stirring rod 642 is rotatably connected in the connecting holes; a planetary gear 655 is rotatably mounted on the second stirring rod 642; a gear ring 656 is mounted on the outside of the planetary gear; the gear ring 656 is fixedly connected to the material cylinder 61; the stirring rod 64 extends downward into the material cylinder 61; and the planetary gear 655 meshes with both the gear ring 656 and the sun gear 652.
[0031] During operation, the second motor 651 drives the sun gear 652 to rotate synchronously with the first stirring rod 641. Driven by the sun gear 652, the planetary gear 655 revolves around the sun gear 652 and rotates along the gear ring 656, thereby driving the second stirring rod 642 to perform a compound trajectory of revolution and rotation, which greatly improves the uniformity of raw material mixing.
[0032] Multiple mixing blade mounting clamps 641 are sequentially sleeved and fixed along the axial direction of the first mixing rod 641 and the second mixing rod 642. The connection angles between each mixing blade 644 on the same clamp 643 and the first mixing rod 641 and the second mixing rod 642 are different, and the mixing blades 644 on adjacent clamps 643 are arranged in a stepped staggered manner in the circumferential direction, so that each mixing blade 644 forms a non-aligned distribution structure in the axial direction, which can mix the organic fertilizer raw materials in all directions, avoid the raw materials from clumping, and improve the mixing uniformity of the raw materials.
[0033] The working principle of this invention is as follows: First, the organic fertilizer raw material is put into the feed cylinder 61 of the pretreatment component 6. The second motor 651 of the drive component 65 is started, thereby driving the sun gear 652 to rotate. The sun gear 652 drives the planetary gear 655 to rotate. At this time, the first stirring rod 641 and the second stirring rod 642 rotate. The staggered stirring blades fully stir and disperse the raw material. The pretreated raw material enters the extruder 2 through the conveying pipe 63. The opening and closing of the regulating valve is controlled according to the processing speed of the extruder 2 to avoid the raw material accumulating in the extruder 2 due to the slow extrusion speed, which would affect the extrusion efficiency. The extruder 2 extrudes the raw material into shape and extrudes the material strip through the discharge plate 21. The cutter 22 rotates synchronously to cut the material strip into particles, which fall into the screening component 3 below. The reciprocating motor 342 of the first drive component 34 is started, and the frame 31 drives the multi-layer screening bucket 36 to reciprocate and screen. Particles of different sizes are classified and screened by the corresponding screening bucket 36. At this time, the first stirring rod 641 and the second stirring rod 642 are started. The second motor 651 drives the frame 11 to rotate, which in turn rotates the screening frame 35 and the screening hopper 36. The screening hopper 36, which is full of material on one side of the frame 31, rotates from the side away from the storage hopper 4 to the side closer to the storage hopper 4. Then, the tilt angle of the screening hopper 36 is adjusted by the first hydraulic cylinder 372. Qualified particles slide down to the storage hopper 4 for collection through the guide plate 5, while unqualified particles can be returned for re-granulation. The screening hopper 36 on the other side, which is not full of material, continues to be loaded due to the rotation of the frame 31, located below the extruder 2. When the screening hopper 36 is full of material and rotates to the side closer to the storage hopper 4, the second hydraulic cylinder 374 is activated. At this time, the second set of screening hoppers 36 tilts, and the particles slide down to the storage hopper 4 for collection through the guide plate 5. This realizes an alternating operation mode of screening and receiving material on one side and unloading material on the other side. Screening and collection are seamlessly connected, avoiding material accumulation and solving the problem of intermittent screening and unloading in traditional screening equipment, further improving the continuity of screening operations. In addition, the diameter of the screening holes in the screening hopper 36 can be flexibly adjusted, and the number, installation height and angle of the screening hopper 36 can be flexibly adjusted through the first mounting hole 353 and the second mounting hole 321 to adapt to the screening needs of organic fertilizers with different particle size specifications. The equipment is highly versatile.
