Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to an extrusion granulation molding device for organic fertilizer production. Background Technology

[0002] The extrusion granulation molding device for organic fertilizer production processes fermented, crushed, and mixed organic raw materials such as livestock and poultry manure, straw, and kitchen waste through mechanical extrusion. Using specific molds or molding structures, it compresses and shapes loose materials into granular products with a certain particle size and strength. This solves the problems of loose organic fertilizers being prone to dust and inconvenient for transportation and storage. Furthermore, it optimizes the nutrient release rate of the fertilizer through particle morphology, improving application convenience and utilization efficiency. It is a key technological equipment for realizing the resource-based transformation of organic waste into high-quality fertilizer. A search revealed that patent document CN219615493U discloses a granulation device for organic fertilizer production, comprising a shell with uniformly distributed forming holes at the bottom. A baffle is attached to the inner side of the bottom of the shell, and a threaded hole is formed on one side of the baffle. A U-shaped frame is fixed to the bottom of one side of the shell, and a first rotating shaft is installed through the end of the U-shaped frame. One end of the first rotating shaft is located inside the threaded hole, and a servo motor is fixed to the other end of the first rotating shaft. The design of the baffle in this granulation device for organic fertilizer production allows the raw material at the top of the baffle to be pressed by a pusher plate. Then, by rotating the first rotating shaft, it can move to the inside of the U-shaped frame, allowing the pressed raw material to fall into the forming holes. Then, through the extrusion of the pusher plate, the strip-shaped raw material extruded from the forming holes is compacted, resulting in full and high-quality granules.

[0003] Although the aforementioned patent describes a granulation device for organic fertilizer production, the design of the baffle allows the raw material at the top of the baffle to be compressed by the pusher plate. Then, by rotating the first shaft, the shaft moves into the interior of the U-shaped frame, allowing the compressed raw material to fall into the forming hole. The extruded strip of raw material from the forming hole is then compressed by the pusher plate, resulting in full and high-quality granules. However, there are problems with the inconvenience of changing the pressure roller mold. This is mainly due to the cumbersome disassembly process and the increased difficulty caused by component adhesion and wear. Precise alignment and adjustment are required during installation. The entire process is time-consuming, labor-intensive, and relies on multiple people and specialized tools, thus seriously affecting production continuity, increasing costs, and restricting capacity expansion. Therefore, an extrusion granulation device for organic fertilizer production is proposed to solve these problems. Utility Model Content

[0009] The right sides of the two contraction columns are fixedly connected to the left sides of the two support columns, one right side of the two rotating shafts is fixedly connected to the left side of the power gear, and the other right side of the two rotating shafts is fixedly connected to the left side of the connecting gear.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1 to 3 This utility model provides an embodiment of an extrusion granulation device for organic fertilizer production, comprising an extrusion chamber 1, with a housing 2 fixedly connected to the bottom of the extrusion chamber 1. The housing 2 provides stable support for the extrusion chamber 1 and isolates the internal adjustment mechanism 4 from the external environment, providing protection and dust prevention. A connecting mechanism 3 is rotatably connected to the inner wall of the extrusion chamber 1. The connecting mechanism 3 achieves rotatable engagement with the inner wall of the extrusion chamber 1 through bearings, ensuring flexible operation under power drive. The adjusting mechanism 4 is rotatably connected to the inner wall of the housing 2, its main function being to guide the extruded granular material smoothly into subsequent processing stages. The rotatable connection design makes angle adjustment more convenient and can adapt to granular materials of different particle sizes and flowability.

[0020] A support plate 5 is fixedly connected to the right side of the extrusion chamber 1, providing a stable mounting platform for power components such as the motor 6, ensuring that the motor 6 will not shift its position due to vibration during high-speed operation. The motor 6 is fixedly connected to the top of the support plate 5, serving as the power source for the entire device. Its output shaft is connected to the transmission mechanism via a coupling, converting electrical energy into mechanical energy to power the operation of the connecting mechanism 3. A feed hopper 7 is fixedly connected to the top of the extrusion chamber 1. The feed hopper 7 has a funnel-shaped structure and is fixed to the top feed inlet of the extrusion chamber 1 by welding or bolting, ensuring that the raw material can fall naturally into the extrusion chamber 1 by gravity. The connecting mechanism 3 includes two rotating shafts 31, which are key shaft components for transmitting power and driving the mold column 32 to rotate.

[0021] The right sides of the two rotating shafts 31 are rotatably connected to the inner right side of the extrusion chamber 1. The right sides of the rotating shafts 31 are rotated with the inner right side of the extrusion chamber 1 via rolling bearings. Each of the two rotating shafts 31 is fixedly connected to a die column 32. The outer surface of the die column 32 has uniformly distributed semi-cylindrical grooves, which correspond to the grooves of the other die column 32 to form complete die holes. During the rotation of the die column 32, the raw material is extruded into the die hole to achieve molding. This fixed connection ensures the synchronous operation of the die column 32 and the rotating shaft 31, guaranteeing consistent granulation size. Support columns 33 are fixedly connected to the middle of each of the two die columns 32, enhancing the structural strength of the die column 32 and preventing deformation under high pressure. Simultaneously, the support columns 33 provide mounting points for the connecting block 34, achieving uniform force transmission.

[0022] Multiple connecting blocks 34 are fixedly connected to the left side of each of the two support columns 33. These connecting blocks 34 are evenly welded to the left surface of the support column 33 in a radial distribution and have internal shaft holes for mounting connecting shaft 35. The number and position of the connecting blocks 34 correspond one-to-one with the shrinking rods 36, ensuring that the shrinking rods 36 are evenly stressed. Connecting shaft 35 is rotatably connected inside each of the multiple connecting blocks 34. The rotational engagement between connecting shaft 35 and connecting blocks 34 allows the shrinking rods 36 to swing flexibly around connecting shaft 35. The shrinking rods 36 are fixedly connected to the outside of each of the multiple connecting shafts 35. When the mold column 32 needs to be disassembled, the contraction of the shrinking rods 36 reduces the connection resistance between components. Connecting shaft 37 is fixedly connected to the left side of each of the multiple shrinking rods 36. The function of connecting shaft 37 is to connect the shrinking rods 36 to rotating shaft 38, while also allowing the shrinking rods 36 to rotate around rotating shaft 38, enabling multi-angle swing adjustment of the shrinking rods 36.

[0023] Multiple connecting shafts 37 are externally rotatably connected to rotating shafts 38, whose main function is to concentrate and transmit the force of multiple contraction rods 36. Simultaneously, they serve as guide shafts for adjusting the position of the mold column 32. The rotatable connection ensures that the swaying of the contraction rods 36 does not affect the stability of rotating shafts 38. Two rotating shafts 38 are externally slidably connected to guide components 39. Guide components 39 form a sliding fit with the outside of rotating shafts 38 through sliding sleeves or bearings, ensuring the stability and adjustment accuracy of the connecting mechanism 3.

[0024] Reference Figures 2 to 4 The adjustment mechanism 4 includes a guide plate 41, whose left and right sides are slidably connected to the inner wall of the outer casing 2. This sliding connection allows the guide plate 41 to flexibly adjust its tilt angle along the inner wall of the outer casing 2. A connecting shaft 3 42 is rotatably connected to the front inner wall of the guide plate 41, serving as the rotation fulcrum for the front of the guide plate 41 and providing rotational support for angle adjustment. A connecting shaft 43 is rotatably connected to the rear inner wall of the guide plate 41. The connecting shaft 43 and the connecting shaft 3 42 form a symmetrical rotational support structure, jointly bearing the weight of the guide plate 41 and coordinating with the angle adjustment action. Movable columns 44 are fixedly connected to both the left and right sides of the connecting shaft 43. The movable columns 44 are intermediate components connecting the connecting shaft 43 to the inner wall of the outer casing 2. Their movement drives the connecting shaft 43 to move up and down, thereby pushing the rear side of the guide plate 41 to rise and fall to change its angle.

[0025] Both movable columns 44 are internally fixedly connected to limit strips 45, which are embedded inside the movable columns 44 and cooperate with the limit grooves of the outer shell 2 to limit the position of the movable columns 44 after adjustment. Telescopic rods 46 are fixedly connected to the adjacent sides of both movable columns 44. Telescopic columns 47 are fixedly connected to the top of the left and right sides of the connecting shaft 43, supporting the up-and-down movement of the connecting shaft 43 through their own telescopic changes, providing vertical support for the angle adjustment of the guide plate 41, and buffering the vibration generated by particle impact. Springs 48 are fitted on the outside of both telescopic rods 46 to prevent displacement of the movable columns 44 due to vibration, and to provide damping during angle adjustment, making the adjustment process smoother. Control columns 49 are fixedly connected to the distant sides of both limit strips 45, extending to the outside of the outer shell 2, allowing operators to control the movement of the limit strips 45 and movable columns 44 externally.

[0026] Reference Figures 1 to 3The guide assembly 39 includes two fixed rings 391, which are the basic positioning components of the guide assembly 39. Through a fixed connection with the inner wall of the mold column 32, they provide stable support for the movement of the second rotating shaft 38. The inner walls of the two fixed rings 391 are slidably connected to the outer left side of the two second rotating shafts 38. The smooth treatment of the inner walls of the fixed rings 391 reduces sliding friction, ensuring smooth movement of the second rotating shaft 38 and reducing component wear. A movable ring 392 is fixedly connected to the outer right side of each of the two second rotating shafts 38. The movable ring 392 moves synchronously with the second rotating shaft 38, and through a sliding engagement with the inner wall of the mold column 32, further enhances the movement stability of the second rotating shaft 38.

[0027] Both rotating shafts 38 have slidably connected limit rings 393 on their right outer sides. These limit rings 393 are fixed to the inner wall of the mold column 32, rigidly restricting the movement range of the moving ring 392 and rotating shafts 38, preventing structural misalignment due to excessive movement of the rotating shafts 38. Both rotating shafts 38 have fixedly connected contraction columns 394 on their right sides. When rotating shafts 38 move, the contraction columns 394 extend and retract, causing the support columns 33 to move synchronously, achieving coordinated adjustment of the mold column 32's position. Both rotating shafts 38 have springs 395 fitted on their right outer sides. When the external force disappears, the spring force pushes the rotating shafts 38 back to their initial position, ensuring stable connection of the mold column 32 in a non-disassembled state. These springs also act as a buffer during adjustment, reducing component impact.

[0028] A power gear 396 is fixedly connected to the left drive section of motor 6. The power gear 396 is a key component for power transmission, converting the rotational power of motor 6 into gear meshing transmission. Through its cooperation with connecting gear 397, it achieves power diversion, providing synchronous rotational power to the two rotating shafts 31. A connecting gear 397 is rotatably connected to the right inner wall of housing 2. The connecting gear 397 meshes with the power gear 396, enabling the two rotating shafts 31 to rotate synchronously in opposite directions, meeting the working requirements of the die column 32 extruding raw materials. The rotatable connection ensures smooth gear meshing and reduces transmission noise. Two guide plates 398 are fixedly connected to the inner wall of housing 2 to prevent particle accumulation and residue within housing 2. The inclined angle design accelerates particle flow and improves conveying efficiency. The fixed connection ensures structural stability under particle impact.

[0029] Two fixed rings 391 are externally fixedly connected to the inner left walls of the two mold pillars 32. When the mold pillars 32 need to be adjusted or disassembled, the fixed rings 391 move synchronously with the mold pillars 32, ensuring the coordination of the movement of the guide assembly 39 and the mold pillars 32, and avoiding the impact of loose connection on the guiding accuracy. Two limiting rings 393 are externally fixedly connected to the inner walls of the two mold pillars 32. The fixed connection between the limiting rings 393 and the mold pillars 32 makes them part of the structure of the mold pillars 32, which can accurately limit the movement range of the rotating shaft 38 and the moving rings 392. Two moving rings 392 are externally slidably connected to the inner walls of the two mold pillars 32. The sliding connection allows the moving rings 392 to move freely with the rotating shaft 38. At the same time, the inner walls of the mold pillars 32 provide guiding support for the moving rings 392, ensuring that the moving rings 392 always move along the axial direction. Together with the fixed rings 391 and the limiting rings 393, they constitute a multi-guided limiting system for the rotating shaft 38.

[0030] The right sides of the two shrinking columns 394 are fixedly connected to the left sides of the two supporting columns 33. When the rotating shaft 38 moves, the shrinking columns 394 can extend and retract to synchronously adjust the position of the supporting columns 33, achieving linkage and coordination of the internal structure of the die column 32 and ensuring uniform extrusion force. One right side of one of the two rotating shafts 31 is fixedly connected to the left side of the power gear 396. This connection directly transmits the rotation of the power gear 396 to the corresponding rotating shaft 31, enabling the rotating shaft 31 to obtain driving force and drive the die column 32 to rotate. The fixed connection ensures efficient power transmission. The other right side of the two rotating shafts 31 is fixedly connected to the left side of the connecting gear 397. Through the meshing transmission between the connecting gear 397 and the power gear 396, the rotating shaft 31 obtains rotational power in the opposite direction to the other rotating shaft 31, realizing the opposing rotation of the two die columns 32 and meeting the motion requirements of raw material extrusion molding.

[0031] The external parts of the power gear 396 and the connecting gear 397 are meshed, ensuring that the two gears rotate synchronously and in opposite directions. This allows the two rotating shafts 31 and the die column 32 to rotate precisely in opposite directions, ensuring uniform force on the raw material during extrusion. The left sides of the two rotating shafts 38 are rotatably connected to the left inner wall of the outer casing 2. This rotatable connection provides a left support point for the rotating shafts 38, ensuring stability during axial movement and rotation with the die column 32. The support structure of the inner wall of the outer casing 2 enhances the load-bearing capacity of the rotating shafts 38, preventing bending deformation due to excessive force. Limiting grooves are provided on both the left and right sides of the outer casing 2, providing guide tracks for the movement of the limiting strips 45. The external parts of the two limiting strips 45 are fixedly connected to the left and right inner walls of the outer casing 2, providing stable guide support for the moving column 44 and ensuring precise operation of the adjusting mechanism 4.

[0032] The two movable columns 44 are externally slidably connected to the left and right inner walls of the outer casing 2. This slid connection allows the movable columns 44 to move up and down along the inner wall of the outer casing 2, providing space for the angle adjustment of the guide plate 41. The top ends of the two telescopic columns 47 are fixedly connected to the left and right inner walls of the outer casing 2. This fixed connection provides an upper support point for the telescopic columns 47, enabling them to stably apply support force to the connecting shaft 43. Simultaneously, the telescopic columns 47 can adjust their length as the connecting shaft 43 moves, adapting to changes in the angle of the guide plate 41. The adjacent sides of the two telescopic rods 46 are fixedly connected to the left and right inner walls of the connecting shaft 43. When the connecting shaft 43 moves, the telescopic rods 46 can balance the force on the movable columns 44 on both sides through extension and retraction, ensuring uniform force on the connecting shaft 43 and preventing the guide plate 41 from tilting. The two springs 48 are externally slidably connected to the left and right inner walls of the connecting shaft 43. The slidable connection allows the springs 48 to freely deform with the extension and retraction of the telescopic rod 46. The elastic force of the springs 48 can provide a reset and buffering effect on the telescopic rod 46.

[0033] Working principle: When the mold column 32 needs to be disassembled, the fixing structure of the fixed ring 391 and the inner wall of the left side of the mold column 32 drives the rotating shaft 38 to slide along the limiting ring 393. The moving ring 392 slides synchronously with the rotating shaft 38 on the inner wall of the mold column 32. The connection structure between the left side of the support column 33 and the shrinking column 394 pushes the shrinking column 394 to extend and retract, thereby driving the spring 395 to compress or reset. The fixing structure between the connecting block 34 and the support column 33 drives the connecting shaft 35 to rotate. The rotating structure of the connecting shaft 35 drives the shrinking rod 36 to swing around the connecting shaft 37 as the fulcrum. The rotating shaft 38 moves along the fixed ring 391 and the limiting ring 393 under the sliding action of the guide component 39. The shrinking rod 36 swings with the rotating shaft 38 to achieve shrinkage. The elastic reset force of the spring 395 assists the rotating shaft 38 to reset and adjust, thereby achieving the convenient disassembly of the mold column 32 and the extrusion chamber 1, greatly reducing the difficulty of replacing and maintaining the mold column 32.

[0034] In the adjustment mechanism 4, the fixed structure of the left and right side limiting slide grooves and limiting strips 45 of the outer shell 2 restricts the sliding trajectory of the moving column 44. The connection structure between the control column 49 and the limiting strip 45 drives the moving column 44 to slide along the inner wall of the outer shell 2. The fixed structure between the moving column 44 and the connecting shaft 43 drives the connecting shaft 43 to move synchronously. The connection structure between the left and right sides of the connecting shaft 43 and the telescopic rod 46 causes the telescopic rod 46 to extend and retract with the moving column 44, thereby driving the spring 2 48 to compress or extend. The fixed structure between the top of the connecting shaft 43 and the telescopic column 47 restricts the range of movement of the connecting shaft 43. At the same time, the rotating connection structure between the connecting shaft 3 42, the connecting shaft 43 and the inner wall of the guide plate 41 causes the guide plate 41 to rotate around the connecting shaft 3 42 as the connecting shaft 43 moves. When the control column 49 is operated, the moving column 44 slides under the guidance of the limit bar 45, thereby changing the angle between the guide plate 41 and the inner wall of the outer shell 2, thus achieving a flexible adjustment effect of the angle of the guide plate 41. The material flow direction can be precisely controlled according to the particle conveying requirements, thereby improving the discharge efficiency.

[0035] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
