Description

Technical Field

[0001] This invention relates to the field of fertilizer preparation technology, and in particular to a multi-material precise proportioning and cross-contamination prevention device for an organic fertilizer batching apparatus. Background Technology

[0002] In the production and processing of organic fertilizer, it is necessary to mix a variety of raw materials such as decomposed manure, straw, wood ash, microbial agents, humic acid, and trace element additives in a fixed proportion. The batching equipment is the core device to ensure that the organic fertilizer product has uniform nutrients and a unified formula standard. The preparation of organic fertilizer requires the use of proportioning equipment, which mixes a variety of raw materials in a certain proportion. Existing mixing equipment uses a shared silo and conveying channel structure, with multiple raw materials sharing a single conveying pipeline. Residual powder and granules from the previous batch adhere to the inner wall of the pipeline, and when the raw materials are changed for the next batch, residual materials mix with the new raw materials. Different nutrients, microorganisms, and additives are mixed together, not only disrupting the preset formula ratio but also causing microbial inactivation and nutrient imbalance, severely affecting the quality of the finished organic fertilizer. Furthermore, the mixing mechanism only has a single layer of spiral blades, which can only circulate material in the middle of the cylinder during mixing. Heavy manure and trace element powder easily settle and accumulate at the bottom of the cylinder, while light straw and microbial agents float and stratify at the top. The blades lack a turbulent flow structure, and the material only moves in one direction, preventing sufficient intermingling and blending of light and heavy materials, resulting in a mixing uniformity that does not meet organic fertilizer production standards. Therefore, there is an urgent need to provide a multi-material precise mixing and cross-contamination prevention device for organic fertilizer batching. Summary of the Invention

[0008] Preferably, two limiting blocks are fixedly provided on the inner wall of the mixing cylinder, bearing four is fixedly provided through the front and back of the bottom of the mixing cylinder, a through rod is provided through the middle of the two bearing four, the outer surface of the through rod is fixedly sleeved with material distributing teeth, and two alignment rods are fixedly provided at the end of the through rod.

[0009] Preferably, the large bevel gear simultaneously meshes with multiple small bevel gears, multiple transverse rods simultaneously remain perpendicular to the central rod, and the second bearing is fixedly sleeved on the other end of the transverse rod and the top of the central rod.

[0010] Preferably, the power output end at the bottom of the servo motor is fixed to the top of the central rod, the axial direction of the central rod is coaxial with the axial direction of the mixing cylinder, the central rod is rotatably installed through the top of the mixing cylinder via bearing one, and the transverse rod is rotatably installed through one end of the conveying pipe via bearing three.

[0011] Preferably, the large spiral blade, the medium spiral blade, and the small spiral blade are fixed around the outer surface of the central rod. The number of large spiral blades is less than the number of medium spiral blades, the number of medium spiral blades is less than the number of small spiral blades, and the spiral spacing of the large spiral blades is consistent with that of the medium spiral blades, and the spiral spacing of the medium spiral blades is consistent with that of the small spiral blades.

Various organic fertilizer raw materials, such as composted manure, straw, wood ash, microbial agents, and trace elements, are stored and conveyed separately, completely eliminating the need for shared silos in traditional batching equipment. A long spiral blade is fixed externally to the transverse rod of the conveying mechanism. When the servo motor reverses, the long spiral blade pushes the powder and particles adhering to and remaining on the inner wall of the conveying pipe, returning all residual material to the corresponding mixing cylinder, eliminating dead zones for material accumulation in the pipeline. Combined with the baffle plate structure at the outlet of the conveying pipe, it prevents fine powder from entering the bevel gears. The meshing area prevents materials from getting stuck in the gears, causing tooth skipping and transmission failure, and also prevents various raw materials from accumulating and mixing in the gaps between the transmission gears. This dual structure ensures no cross-contamination throughout the entire process and is suitable for continuous rotation production of multiple formulas and batches of organic fertilizer. The counterclockwise rotation of the servo motor has two functions: first, the long spiral blades rotate in the opposite direction to push the residual raw materials in the conveying pipe back to the mixing cylinder, completing the self-cleaning of the pipeline and eliminating the need for manual cleaning of the pipeline when switching formulas; second, the multi-layer spiral blades push the mixed organic fertilizer in the cylinder downwards, and with the detachable threaded cover at the bottom, the material is quickly unloaded. The unloading speed is fast, the fertilizer in the cylinder is completely emptied, and there is no waste of finished product residue. Attached Figure Description

Detailed Implementation

[0017] Reference Figures 1 to 11 This is an organic fertilizer batching device with multi-material precise proportioning and anti-cross-contamination features. The device relies on a bottom plate 1, a support frame 2, an independent conveying mechanism, an integrated mixing mechanism, and multiple sets of independent proportioning cylinders 5 working in synergy to achieve zoned storage of various organic fertilizer raw materials, quantitative intermittent feeding, synchronous isolated conveying, multi-layer turbulent mixing within the cylinders, and reverse blocking of residual material backflow throughout the entire process. By using independent pipelines and a single-compartment, single-pipe conveying structure, different raw materials are isolated at the source, completely eliminating cross-contamination and residual material mixing. Simultaneously, a single-servo synchronous transmission structure uniformly controls the feeding speed of each path, stably achieving precise multi-material proportioning production. The device includes: a bottom plate 1, with a support frame 2 fixedly mounted on its top. The bottom plate 1 serves as the base for the entire machine, providing a flat surface for the support frame 2, conveying mechanism, mixing mechanism, and proportioning cylinders 5. The entire installation is based on the following: the support frame 2 raises all working components, reserving space for bottom unloading, and simultaneously provides layered positioning support for the conveying pipe 4, mixing cylinder 3, and proportioning cylinder 5 to ensure the stability of the assembly position of each mechanism; the conveying mechanism is fixedly set on the top of the support frame 2; the conveying mechanism consists of multiple sets of independent conveying pipes 4, horizontal rods 42, and long spiral blades 43 forming a single-channel conveying unit, with each unit corresponding to a separate proportioning cylinder 5, and they are not interconnected; synchronous transmission is achieved by the meshing of the large bevel gear 39 and the small bevel gear 45, and the raw materials can be conveyed to the mixing cylinder 3 by the forward rotation of the servo motor 33, and the residual material on the inner wall of the conveying pipe 4 is pushed back to the proportioning cylinder 5 by the reverse rotation, so as to avoid the residual raw materials from mixing into the next batch of materials. Cross-contamination is prevented by the physical isolation of independent pipelines, and synchronous transmission ensures that the conveying speed of each material is consistent, thus ensuring the proportioning accuracy.

[0018] In this invention, the stirring mechanism is fixedly mounted on the top of the support frame 2. The stirring mechanism uses the mixing cylinder 3 as the mixing chamber, and the servo motor 33 and the central rod 32 serve as the sole power hub of the entire system. On one hand, it drives the large spiral blades 310, medium spiral blades 311, and small spiral blades 312 inside to complete the multi-layer circulating mixing of organic fertilizer. On the other hand, it synchronously drives all conveying mechanisms through the top large bevel gear 39. When the equipment rotates forward, the material continuously flows and mixes evenly. In reverse mode, the spiral blades push the material downwards, working in conjunction with the detachable threaded cover 313 to complete the mixing process. The mixed fertilizer is quickly unloaded; the bottom of multiple proportioning cylinders 5 is fixedly set on the top of the conveying mechanism; multiple sets of proportioning cylinders 5 are independently separated and store different raw materials such as straw, microbial agents, and decomposed manure required for organic fertilizer production. The bottom of the box is equipped with a limiting block 51, a through rod 53, and a distributing tooth 54 to form a quantitative distributing component. The manual operation of the alignment rod 55 controls the rotation angle and frequency of the distributing tooth 54. Every 180° rotation releases a fixed volume of raw materials, realizing intermittent, uniform, and quantitative feeding, providing a stable feeding basis for the precise proportioning of multiple materials.

[0019] In this invention, the conveying mechanism includes: conveying pipes 4, multiple conveying pipes 4 are fixedly installed on the top of the support frame 2; each conveying pipe 4 connects only a single proportioning cylinder 5 and a mixing cylinder 3, and the internal space of each conveying pipe 4 is completely independent with no interconnection channels, physically isolating different raw materials from the conveying path and avoiding cross-contamination of raw materials from the source; the tubular sealed structure reduces the overflow of organic fertilizer dust and improves the workshop working environment; bearings 3 41, multiple bearings 3 41 are respectively fixed through one end of multiple conveying pipes 4; the bearings 3 41 are nested at the end of the conveying pipes 4, providing radial and axial limiting support for one end of the transverse rod 42, reducing the rotational friction resistance of the transverse rod 42, reducing the shaking and noise when the long spiral blade 43 conveys materials, and extending the service life of the transmission components.

[0020] In this invention, a horizontal rod 42, one end of which is respectively installed through the middle of a plurality of bearings 41; the horizontal rod 42 is the bearing drive shaft of the long spiral blade 43, the body of the horizontal rod 42 extends through the entire conveying pipe 4, one end is positioned by the bearing 41, and the other end extends out of the conveying pipe 4 and is rigidly connected to the small bevel gear 45, synchronously receiving the torque transmitted by the large bevel gear 39, driving the long spiral blade 43 to rotate at a uniform speed to convey materials; the long spiral blade 43, a plurality of which are fixedly installed on the outer surface of the plurality of horizontal rods 42; the long spiral blade 43 rotates synchronously with the horizontal rod 42, when rotating in the forward direction, the spiral blade continuously pushes the organic fertilizer raw material falling from the proportioning cylinder 5 to move towards the mixing cylinder 3, completing the quantitative feeding; when rotating in the reverse direction, the spiral blade pushes the residual material in the pipe back to the proportioning cylinder 5, clearing the pipe residue and preventing batch mixing and cross-contamination.

[0021] In this invention, baffle plates 44, multiple baffle plates 44 are respectively fixedly sleeved on the other end of the transverse rod 42; the baffle plates 44 are located between the outlet of the conveying pipe 4 and the small bevel gear 45, forming an annular isolation baffle, preventing fine organic fertilizer powder and particles inside the conveying pipe 4 from entering the meshing area of ​​the small bevel gear 45, avoiding material jamming on the gear tooth surface, and preventing transmission jamming, tooth skipping, and power failure; docking ends 46, multiple docking ends 46 are respectively integrally formed and fixedly set on the other end of the transverse rod 42; the docking ends 46 are integrally formed with the transverse rod 42, and the ends have flange positioning structures, serving as a precise assembly base for the small bevel gear 45, ensuring that the small bevel gear 45 and the transverse rod 42 are coaxially fixed without gap, and the transmission torque is transmitted without loss.

[0022] In this invention, multiple small bevel gears 45 are fixedly sleeved on the docking end 46 at the other end of the transverse rod 42. Each small bevel gear 45 corresponds to one conveying mechanism. All small bevel gears 45 mesh synchronously with the large bevel gear 39. The power output by the servo motor 33 is evenly distributed to all small bevel gears 45 through the central rod 32 and the large bevel gear 39, so that the rotation speed of all transverse rods 42 and long spiral blades 43 is completely consistent, ensuring that the feeding speed of different raw materials strictly matches the preset ratio. Multiple feed inlets 47 are respectively set at the top of the conveying pipe 4, and the proportioning cylinder 5 and the conveying pipe 4 are kept connected through the inside of the feed inlets 47. The feed inlets 47 are opened directly above the top of the conveying pipe 4 and are directly connected to the bottom outlet of the proportioning cylinder 5 to form a closed feeding channel. The quantitative raw materials released by the dividing teeth 54 fall smoothly into the inside of the conveying pipe 4 through the feed inlets 47, with no material spillage and no dust leakage, ensuring stable feeding and metering.

[0023] In this invention, the stirring mechanism includes: a mixing cylinder 3, the bottom of which is fixedly mounted on the top of the support frame 2; the mixing cylinder 3 is a vertical, sealed cylindrical cavity, which is the core space for the centralized mixing of various organic fertilizer raw materials, and multiple interfaces are opened on the side to connect to each conveying pipe 4, receiving the raw materials conveyed by each independent conveying channel; the mixing cylinder 3 has sufficient internal space to accommodate multi-layer spiral reciprocating stirring, and the bottom is fitted with a threaded cover 313 to achieve the switching between sealed material storage and finished product unloading; a bearing 31, which is fixedly mounted through the top of the mixing cylinder 3; the bearing 31 is embedded in the center of the top cover of the mixing cylinder 3, supporting and positioning the upper part of the central rod 32, limiting the radial displacement of the central rod 32 when it rotates at high speed, ensuring that the central rod 32 rotates coaxially with the mixing cylinder 3 throughout the entire process, and reducing the vibration of the stirring spiral.

[0024] In this invention, a central rod 32 is installed through the middle of bearing 31. The central rod 32 is the double-layer transmission main shaft of the whole machine. The upper section is connected to the power output end of servo motor 33. The top is equipped with a protruding rod 37 and a large bevel gear 39 to drive all conveying mechanisms. The middle and lower sections of the central rod 32 are fixed with multiple spiral blades, which drive the organic fertilizer in the cylinder to continuously turn and mix. One main shaft simultaneously completes the two functions of power distribution and material mixing. Vertical rods 34 are fixed at the bottom of multiple vertical rods 34 and are evenly arranged around the top of the mixing cylinder 3. The multiple vertical rods 34 support the servo motor 33 from the top, raising the installation height of the motor and making the output shaft of the servo motor 33 accurately aligned with the top of the central rod 32, eliminating the transmission vibration caused by assembly eccentricity.

[0025] In this invention, a servo motor 33 is fixedly mounted at the top of multiple vertical rods 34. The servo motor 33 is the sole power source for this equipment, supporting forward rotation, reverse rotation, and speed control. In forward rotation, it synchronously drives the long spiral blades 43 for feeding and multi-layer spiral blades for mixing. In reverse rotation, it drives the long spiral blades 43 to return material and block feeding, while the spiral blades push the finished fertilizer downwards for unloading. A single motor uniformly controls all process actions, simplifying the overall power control system. A large bevel gear 39 is fixedly sleeved on the periphery of the protruding rod 37. The large bevel gear 39 is the main drive gear, and its gear ring meshes perpendicularly with all the small bevel gears 45 of the equipment, evenly distributing the torque output by the servo motor 33 to each horizontal rod 42, achieving synchronous start-stop and synchronous speed adjustment of multiple conveying mechanisms, ensuring a constant feed ratio of each raw material from a power perspective.

[0026] In this invention, the stirring mechanism further includes: a fixing frame 35, multiple fixing frames 35 are fixedly installed on the inner wall of the mixing cylinder 3; the fixing frame 35 extends laterally along the inner wall of the mixing cylinder 3 to provide a fixed installation point for the bearing 36, and each set of transverse rods 42 corresponds to a set of fixing frames 35 at the end, realizing auxiliary support at the end of the conveying mechanism; bearing 36, multiple bearings 36 are respectively fixedly installed at the bottom and side of multiple fixing frames 35; bearing 36 is sleeved on the end of the transverse rod 42 extending out of the conveying pipe 4, forming a double-support structure at both ends with bearing 41, offsetting the radial impact force generated when the long spiral blade 43 pushes the material, avoiding bending deformation of the slender transverse rod 42 under long-term load, and continuously ensuring the conveying and metering accuracy.

[0027] In this invention, a protruding rod 37 is integrally formed and fixedly disposed on the top of the central rod 32; the protruding rod 37 and the central rod 32 are integrally formed, and the outer side of the rod body is integrally formed with a raised anti-slip structure, which serves as the inner hole positioning shaft of the large bevel gear 39. The torque is transmitted by the engagement of the raised strip with the inner hole of the gear, preventing the large bevel gear 39 from slipping relative to the central rod 32; a limiting plate 38 is integrally formed and fixedly disposed on the top of the central rod 32; the limiting plate 38 is an annular boss structure, located below the protruding rod 37, and axially abuts against the lower end face of the large bevel gear 39, restricting the large bevel gear 39 from moving upward and disengaging from the meshing position when it is engaged at high speed, ensuring that all small bevel gears 45 are continuously and stably engaged and transmitted.

[0028] In this invention, the stirring mechanism further includes: a large spiral blade 310, with multiple large spiral blades 310 fixedly disposed on the outer surface of the central rod 32; the large spiral blades 310 have the largest spiral outer diameter and are arranged in the upper region of the central rod 32. When rotating, they can lift the material in the upper middle part of the mixing cylinder 3 over a large area, driving most of the organic fertilizer raw materials in the cylinder to circulate upwards as a whole, thus constructing a large-scale material circulation convection system; and a medium spiral blade 311, with multiple medium spiral blades 311 fixedly disposed on the outer surface of the central rod 32; the outer diameter of the medium spiral blades 311 is between that of the large spiral blades 310 and the small spiral blades 312, and they are arranged in the middle of the cylinder as an intermediate guide layer, receiving the rising material from the bottom and diffusing it towards the middle of the cylinder, forming a double-layer convection with the large spiral blades 310, thus reducing the material stratification area.

[0029] In this invention, small spiral blades 312 are fixedly disposed on the outer surface of the central rod 32. The small spiral blades 312 have the smallest spiral outer diameter and are densely arranged near the bottom of the central rod 32 to specifically stir the organic fertilizer powder and agglomerated materials deposited at the bottom of the mixing cylinder 3, preventing the settling and accumulation of heavy raw materials and eliminating the mixing dead corner at the bottom of the cylinder. Threaded caps 313 are threadedly fitted onto the bottom of the mixing cylinder 3. The threaded caps 313 and the bottom of the mixing cylinder 3 are threadedly sealed together, completely sealing the bottom of the cylinder during the mixing stage to prevent raw material leakage. After mixing is completed, the bottom outlet of the cylinder can be rotated and disassembled to open, and the entire finished organic fertilizer can be quickly discharged by rotating the spiral in reverse.

[0030] In this invention, multiple levers 314 are fixed at one end to the outer surface of the threaded cover 313. These levers 314 are distributed along the outer circumference of the threaded cover 313, serving as a labor-saving handle for manual operation. No wrench or other auxiliary tools are needed; the threaded cover 313 can be rotated and disassembled directly by hand, simplifying the unloading process. Multiple notches 315 are located on the outer sides of multiple large spiral blades 310 and multiple medium spiral blades 311. Through-hole notches 315 are opened on the edges of the large and medium spiral blades 310 and 311. When the spiral pushes the material upwards, some organic fertilizer passes through the notches 315 and flows back towards the cylinder wall, creating a turbulent backflow effect. The combination of multiple spirals and notches 315 continuously disrupts the material stratification, significantly improving the mixing uniformity of various organic fertilizers with different specific gravities.

[0031] In this invention, two limiting blocks 51 are fixedly installed on the inner wall of the mixing cylinder 5; the two limiting blocks 51 are symmetrically arranged on both sides of the distributing tooth 54, limiting the maximum single rotation stroke of the distributing tooth 54, preventing the raw material from being poured out in large quantities at once, constraining the single material volume that the tooth groove of the distributing tooth 54 can hold, stabilizing the single feeding weight, and reducing the mixing measurement error; bearings 52 are fixedly installed through the front and back sides of the bottom of the mixing cylinder 5, and a through rod 53 is installed through the middle of the two bearings 52; the two sets of bearings 52 are symmetrically installed on the front and back side walls of the bottom of the mixing cylinder 5, jointly supporting the two ends of the through rod 53, forming a double-sided symmetrical support structure, reducing the rotational sway of the through rod 53, ensuring that the distributing tooth 54 rotates smoothly and the feeding flow is uniform.

[0032] In this invention, a material distribution tooth 54 is fixedly sleeved on the outer surface of the through rod 53; the material distribution tooth 54 is the core component for quantitative feeding, with more than 4 teeth, and an independent storage trough is formed between the teeth; the raw material in the proportioning cylinder 5 falls into the tooth groove for storage, and every time the tooth groove is rotated 180° downward, the quantitative raw material in the trough falls completely into the feed port 47, and standardized quantitative feeding is achieved by relying on the fixed volume, ensuring accurate and controllable proportioning of multiple materials; two alignment rods 55 are fixedly installed at the end of the through rod 53; the alignment rods 55 extend out of the outside of the proportioning cylinder 5 and serve as external manual operation handles. The operator can rotate the alignment rods 55 to drive the through rod 53 and the material distribution tooth 54 to rotate synchronously, and can flexibly control the rotation angle and rotation frequency of the material distribution tooth 54, and adjust the total amount and feeding speed of a single raw material as needed.

[0033] In this invention, the large bevel gear 39 simultaneously meshes with multiple small bevel gears 45, and multiple transverse rods 42 simultaneously remain perpendicular to the central rod 32. The second bearing 36 is fixedly sleeved on the other end of the transverse rod 42 and the top of the central rod 32. The large bevel gear 39 meshes with all the small bevel gears 45 at a 90-degree angle, and the torque is split without speed difference, so that the conveying speed of each transverse rod 42 and the long spiral blade 43 is completely uniform, ensuring that the feeding ratio of each proportioning cylinder 5 strictly matches the formula. The second bearing 36 simultaneously supports the end of the transverse rod 42 and the upper part of the central rod 32, forming a cross-stable support frame to counteract the bidirectional radial force generated during the conveying and stirring process, and to avoid deformation of the rods and inaccurate conveying and metering.

[0034] In this invention, the power output end of the servo motor 33 at the bottom is fixed to the top of the central rod 32. The axial direction of the central rod 32 is coaxial with the axial direction of the mixing cylinder 3. The central rod 32 is rotatably installed through the top of the mixing cylinder 3 via bearing 31, and the transverse rod 42 is rotatably installed through the end of the conveying pipe 4 via bearing 41. The output shaft of the servo motor 33 is rigidly connected to the central rod 32 coaxially. The central rod 32 coincides with the central axis of the mixing cylinder 3, eliminating material deviation caused by eccentric stirring. Bearing 31 independently supports the central rod 32, and bearing 41 independently supports each transverse rod 42. Each rotating component is supported separately and does not interfere with each other. The servo motor 33 is uniformly adjusted for forward and reverse rotation speed, synchronously controlling the entire process of feeding the long spiral blade 43, multi-layer spiral stirring, and unloading at the bottom of the cylinder. The transmission link is simple and the synchronous control accuracy is high.

[0035] In this invention, large spiral blades 310, medium spiral blades 311, and small spiral blades 312 are fixed around the outer surface of the central rod 32. The number of large spiral blades 310 is less than the number of medium spiral blades 311, and the number of medium spiral blades 311 is less than the number of small spiral blades 312. The spiral spacing of the large spiral blades 310 is consistent with that of the medium spiral blades 311, and the spiral spacing of the medium spiral blades 311 is consistent with that of the small spiral blades 312. The large spiral blades 310, medium spiral blades 311, and small spiral blades 312 form a gradient spiral layout with fewer blades at the top and more blades at the bottom. The densely arranged small spiral blades 312 at the bottom continuously stir the bottom of the cylinder to prevent sedimentation. The medium spiral blades 311 and large spiral blades 310, which decrease in number in the middle and upper parts, lift the material over a large area. The spiral spacing of the three sets of spiral blades is exactly the same, the axial conveying rate of the material is uniform, the vertical circulation velocity of the material in the cylinder is balanced, there is no local stagnation or mixing dead zone, and the uniformity of mixing of various organic fertilizers is greatly improved.

[0037] In this invention, the bottom of the proportioning cylinder 5 is a four-sided pyramid shape, the number of teeth of the distributing teeth 54 is greater than 4, the distributing teeth 54 are located in the middle of the two limiting blocks 51, and the through rod 53 is rotatably disposed through the bottom of the proportioning cylinder 5 via two bearings 52, with the distributing teeth 54 located in the middle of the two bearings 52; the bottom of the four-sided pyramid funnel of the proportioning cylinder 5 tapers inward, and the raw materials inside the box continuously gather towards the bottom distributing teeth 54 by their own weight, and there are no flat material dead corners on the side wall of the box, avoiding the accumulation and clumping of raw materials that affect the feeding; the multi-toothed distributing teeth 54 evenly distribute the raw materials in multiple slots, and the single feeding volume is stable; the distributing teeth 54 are arranged in the middle of the two sets of bearings 52, the two ends of the through rod 53 are symmetrically stressed, the rotation is without sway, the feeding flow fluctuates little, and the accuracy of organic fertilizer batching is further improved.

[0038] In use, firstly, various raw materials are poured into the corresponding mixing cylinders 5. Then, the servo motor 33 drives the central rod 32, protruding rod 37, limiting disc 38, large bevel gear 39, large spiral blade 310, medium spiral blade 311, and small spiral blade 312 to rotate synchronously clockwise. The rotation of the large bevel gear 39 simultaneously drives multiple small bevel gears 45 to rotate synchronously, causing multiple transverse rods 42 and multiple long spiral blades 43 to rotate synchronously. The rotation of the long spiral blades 43 can roll the raw materials inside the conveying pipe 4, allowing the raw materials to enter the mixing cylinder 3 through the conveying pipe 4. The rotation of the large spiral blades 310, medium spiral blades 311, and small spiral blades 312 can roll the raw materials from... Move upwards, then manually rotate the alignment rod 55 180 degrees around the axis of the through rod 53, causing the distributing teeth 54 to rotate 180 degrees inside the bottom of the proportioning cylinder 5. The raw material rotates between the teeth of the distributing teeth 54 and below them, allowing a fixed amount of raw material to be discharged from the bottom of the proportioning cylinder 5 into the conveying pipe 4. The distributing teeth 54 discharge a fixed amount of raw material from the bottom side of the proportioning cylinder 5 every 180 degrees. Then, the raw materials inside the multiple proportioning cylinders 5 are distributed into the multiple conveying pipes 4 according to the proportion. The multiple long spiral blades 43 rotate and roll the raw material, which is then discharged through the other end of the multiple conveying pipes 4 into the mixing cylinder 3. The long spiral blades 43 also carry the raw material inside the conveying pipes 4. All the raw materials are fed into the mixing drum 3. The large spiral blade 310, medium spiral blade 311, and small spiral blade 312 rotate and roll the raw materials from bottom to top. During this process, the raw materials pass through the notch 315 and pass over the outside of the large spiral blade 310 and medium spiral blade 311. As the large spiral blade 310 and medium spiral blade 311 continue to rotate and roll the raw materials from bottom to top, the raw materials will pass through the notch 315 and pass over the outside of the large spiral blade 310 and medium spiral blade 311 multiple times. During this process, the various raw materials are continuously stirred to ensure that they are evenly mixed, thus completing the mixing of the various raw materials. Then, the lever 314 and the threaded cap 313 are rotated by hand. The threaded cap 313 is pushed from the bottom of the mixing drum 3. After disassembly, the servo motor 33 drives the central rod 32, large bevel gear 39, large spiral blade 310, medium spiral blade 311, and small spiral blade 312 to rotate counterclockwise synchronously. The large spiral blade 310, medium spiral blade 311, and small spiral blade 312 rotate and roll the raw material from top to bottom. The mixed raw material moves downward inside the mixing cylinder 3 and is discharged through the bottom of the mixing cylinder 3, completing the raw material discharge. During this process, multiple long spiral blades 43 rotate synchronously and roll the raw material in the opposite direction inside the conveying pipe 4 to prevent subsequent raw materials from entering the mixing cylinder 3. Multiple raw materials are poured into multiple proportioning cylinders 5 respectively, effectively preventing cross-contamination of various raw materials.
