Description

Technical Field

[0001] This application relates to the field of organic raw material fermentation technology, and in particular to a raw material mixing device for organic fertilizer production. Background Technology

[0002] In the field of organic fertilizer production, fermentation is a crucial step, and thorough and uniform mixing of raw materials is essential for improving fermentation efficiency and quality. Currently, in the fermentation process of organic fertilizer production, fermentation tanks are typically used to store the organic fertilizer raw materials, and agitators are used to mix the materials inside.

[0003] However, most existing agitators used in fermentation tanks employ a fixed installation structure, which limits the agitator's position and mixing range. In practical applications, due to the large area of ​​the fermentation tank, the agitator can only mix a portion of the tank, failing to fully cover every corner. This results in uneven mixing of the organic raw materials within the fermentation tank, with some areas potentially being over-mixed while others are under-mixed.

[0004] Uneven mixing prevents microorganisms from contacting nutrients in the raw materials evenly, hindering fermentation and prolonging the fermentation cycle, thus reducing production efficiency. Adding multiple mixing devices to agitate different parts would further increase production costs.

[0005] To address the aforementioned issues, a raw material mixing device for organic fertilizer production is now designed. Utility Model Content

[0006] This application provides a raw material mixing device for organic fertilizer production to solve the problem in related technologies where, due to the large area of ​​the fermentation tank, the agitator can only mix a portion of the fermentation tank and cannot fully cover all corners of the fermentation tank, resulting in uneven mixing of organic raw materials in the fermentation tank.

[0007] In a first aspect, a raw material mixing device for organic fertilizer production is provided, comprising: A fermentation chamber is used to store organic fertilizer raw materials. A support frame is arranged on one side of the fermentation chamber, and two agitators are arranged opposite each other on the support frame. The two sets of agitators are distributed along the width of the fermentation chamber. The fermentation chamber is equipped with a driving component, which is connected to the support frame and is used to drive the support frame to move along the length of the fermentation chamber.

[0008] In some embodiments, the fermentation chamber is a rectangular chamber with an open top and an arc-shaped bottom. One end of the fermentation chamber is provided with multiple discharge pipes, and valves are provided on the discharge pipes.

[0009] In some embodiments, the support frame includes a side plate arranged on one side of the fermentation chamber, a crossbeam provided at one end of the side plate, the crossbeam being located above the fermentation chamber and arranged along the width of the fermentation chamber, and two sets of the agitators being arranged opposite each other on both sides of the crossbeam.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] This application provides a raw material mixing device for organic fertilizer production, which can solve the problem in related technologies where, due to the large area of ​​the fermentation tank, the agitator can only mix a portion of the fermentation tank and cannot fully cover all corners of the fermentation tank, resulting in uneven mixing of organic raw materials in the fermentation tank.

[0020] Please see Figures 1-3A raw material mixing device for organic fertilizer production includes: a fermentation chamber 1 for storing organic fertilizer raw materials, a support frame 2 arranged on one side of the fermentation chamber 1, and two agitators 3 arranged opposite to each other on the support frame 2, with the two sets of agitators 3 distributed along the width of the fermentation chamber 1. The fermentation chamber 1 is provided with a driving component 4, which is connected to the support frame 2 and is used to drive the support frame 2 to move along the length of the fermentation chamber 1.

[0021] Fermentation chamber 1 is used to store organic fertilizer raw materials to be fermented. Support frame 2 serves as the bearing structure for agitator 3, and two agitators 3 are arranged opposite each other on it. In the initial state, agitator 3 is located in the width direction of fermentation chamber 1, ready to agitate the raw materials in the chamber.

[0022] When the agitator 3 starts operating, it agitates the organic fertilizer raw materials within its range of action. Since the two agitators 3 are arranged opposite each other and distributed along the width of the fermentation chamber 1, they can agitate the raw materials from different positions in the width direction of the fermentation chamber 1 at the same time, so that the raw materials are initially mixed in the width direction.

[0023] After the drive unit 4 starts working, it will output power to drive the support frame 2 to move along the length of the fermentation chamber 1. The stirrer 3 is fixedly installed on the support frame 2, so as the support frame 2 moves, the stirrer 3 will also change its position along the length of the fermentation chamber 1.

[0024] During the movement of the support frame 2, the agitator 3 continues to operate. While moving along the length of the fermentation chamber 1, the agitator 3 also performs a stirring action in the width direction, which can carry out all-round stirring of the organic fertilizer raw materials in different positions and areas within the fermentation chamber 1, so that the raw materials are fully mixed within the fermentation chamber 1.

[0025] By arranging the stirrer 3 relative to the width of the fermentation chamber 1, and driving the support frame 2 to move via the drive component 4, the position of the stirrer 3 in the fermentation chamber 1 can be adjusted according to actual needs. This allows the stirring range of the stirrer 3 to cover all corners of the fermentation chamber 1, achieving thorough mixing of the raw materials in the fermentation chamber 1. This facilitates the uniform decomposition and transformation of organic matter in the raw materials by microorganisms, thereby improving the quality and stability of the fermentation products.

[0026] The comprehensive stirring action of stirrer 3 makes the environmental factors such as temperature, humidity, and pH in fermentation chamber 1 more uniform, creating more suitable fermentation conditions for microorganisms and thus accelerating the fermentation process. Compared with traditional stirring devices, this device can shorten the fermentation cycle, improve production efficiency, and reduce production costs.

[0027] The thorough stirring of the agitator 3 ensures that the air in the fermentation chamber 1 is evenly distributed, providing sufficient oxygen for aerobic microorganisms. At the same time, it promotes the discharge of gases such as carbon dioxide produced during fermentation, avoiding local hypoxia or gas accumulation that could have an adverse effect on fermentation.

[0028] In addition, uniform stirring can prevent the raw materials from clumping during fermentation, ensuring the smooth progress of fermentation and further improving the quality and efficiency of fermentation.

[0029] like Figure 1 and Figure 2 As shown in this embodiment, the fermentation chamber 1 is a rectangular chamber with an open top and an arc-shaped bottom. One end of the fermentation chamber 1 is provided with multiple discharge pipes 11, and valves are provided on the discharge pipes 11.

[0030] Organic fertilizer raw materials are fed into the fermentation chamber 1 through the opening at the top. The rectangular chamber can hold a sufficient amount of raw materials.

[0031] The bottom of fermentation chamber 1 is arc-shaped, which makes the raw materials flow more easily during stirring. The power generated by the stirring machine 3 will cause the raw materials to spread and mix along the arc-shaped bottom. Compared with flat-bottomed chambers, the arc-shaped bottom reduces the residue and accumulation of raw materials, making the stirring more uniform and thorough. This is conducive to the full contact between microorganisms and raw materials, and promotes the fermentation reaction.

[0032] Open the valve on the discharge pipe 11 at one end of the fermentation chamber 1, and the organic fertilizer will be discharged smoothly through the discharge pipe 11. The setting of multiple discharge pipes 11 can control the discharge speed.

[0033] like Figure 2 , Figure 3 and Figure 4 As shown, in one embodiment, the support frame 2 includes a side plate 21 arranged on one side of the fermentation chamber 1. A crossbeam 22 is provided at one end of the side plate 21. The crossbeam 22 is located above the fermentation chamber 1 and is arranged along the width of the fermentation chamber 1. Two sets of agitators 3 are arranged opposite to each other on both sides of the crossbeam 22. A plurality of reinforcing plates 23 are provided on the other side of the side plate 21.

[0034] The side plate 21 serves as the main load-bearing component of the entire support frame 2. One end of the side plate 21 is connected to the crossbeam 22, which is positioned above the fermentation chamber 1 and arranged along the width of the fermentation chamber 1. This allows the crossbeam 22 to span the width of the fermentation chamber 1, providing an installation platform for the agitator 3.

[0035] Multiple reinforcing plates 23 play a role in enhancing the structural strength of the support frame 2 during operation.

[0036] like Figure 2 , Figure 3 and Figure 4As shown, in one embodiment, the stirrer 3 includes a fixed base 31 mounted on a crossbeam 22, a drive motor 32 and a reducer 33 mounted on the fixed base 31, the output shaft of the drive motor 32 being connected to the input shaft of the reducer 33, the output shaft of the reducer 33 being provided with a rotating shaft 34, and two sets of stirring blades 35 being mounted on the rotating shaft 34, the stirring blades 35 being located inside the fermentation chamber 1.

[0037] When the agitator 3 is started, the drive motor 32 starts to run and its output shaft rotates. The function of the reducer 33 is to reduce the high-speed rotation of the drive motor 32 while increasing the output torque.

[0038] After adjustment by reducer 33, power is transmitted to its output shaft at a more suitable speed and with greater torque, ensuring that the stirring blades 35 can stir the raw materials with appropriate force and speed. The output shaft of reducer 33 is connected to rotating shaft 34, and power is further transmitted through rotating shaft 34. Two sets of stirring blades 35 are installed on rotating shaft 34, and the stirring blades 35 are located inside fermentation chamber 1. When rotating shaft 34 is driven by power, it drives the two sets of stirring blades 35 to make circular motion together. During the rotation, the stirring blades 35 come into contact with the organic fertilizer raw materials in fermentation chamber 1. Through the thrust and shear force of its blades, the raw materials are stirred and mixed, so that the various components in the raw materials can fully contact and react.

[0039] like Figure 2 , Figure 3 and Figure 4 As shown, further, the number of the stirring blades 35 in a group is four, and the four stirring blades 35 in the same group are arranged in a ring. The stirring blades 35 are petal-shaped, with their sides curving upwards and their middle concave downwards, and the stirring blades 35 are provided with multiple through holes 351.

[0040] A set of four stirring blades 35 are arranged in a ring, so that when the stirring blades 35 rotate around the rotating shaft 34, they can form a relatively uniform stirring coverage area, stirring the organic fertilizer raw materials in the fermentation chamber 1 in all directions, and avoiding the occurrence of stirring dead corners.

[0041] The mixing plate 35 is petal-shaped, with the upward-curving parts on both sides resembling the edges of petals. During rotation, it can generate greater thrust and lift. When the mixing plate 35 comes into contact with the organic fertilizer raw materials, the raised edges can turn the raw materials upward and outward, increasing the relative movement between the raw materials. The downward-concave part in the middle can hold a certain amount of raw materials, allowing for more thorough mixing and stirring of this part of the raw materials during rotation.

[0042] The stirring plate 35 has multiple through holes 351. The through holes 351 reduce the resistance between the stirring plate 35 and the raw material, improve the stirring efficiency, and can achieve the ideal stirring effect in a shorter time.

[0043] like Figure 3 and Figure 5 As shown, in one embodiment, the driving component 4 includes: a housing 41 disposed on the fermentation chamber 1; a power unit 42 disposed at one end of the housing 41; a lead screw 43 rotatably disposed inside the housing 41; a movable cylinder 44 threadedly connected to the lead screw 43; a fixed plate 45 disposed at the top end of the movable cylinder 44; and a movable seat 46 slidably disposed above the housing 41. The movable seat 46 is L-shaped, and a through hole is provided at the top end of the housing 41. The top end of the fixed plate 45 passes through the through hole and is connected to the movable seat 46. The movable seat 46 is connected to the bottom ends of the side plate 21 and the reinforcing plate 23. The power unit 42 is connected to the lead screw 43 for driving the lead screw 43 to rotate.

[0044] The power unit 42 includes a second drive motor and a second reducer disposed on the housing 41. The output shaft of the second drive motor is connected to the input shaft of the second reducer, and the output shaft of the second reducer is connected to one end of the lead screw 43. The moving cylinder 44 has a threaded hole inside that matches the thread on the lead screw 43.

[0045] When drive motor 2 is started, its output shaft begins to rotate at high speed, transmitting the power to the input shaft of reducer 2 connected to it. Reducer 2 reduces the speed of the high-speed power output by drive motor 2, while increasing the output torque.

[0046] The power, after being adjusted by the reducer, is transmitted to one end of the lead screw 43 through its output shaft, causing the lead screw 43 to start rotating. Since the lead screw 43 is matched with the threaded hole inside the moving cylinder 44, according to the principle of threaded transmission, the moving cylinder 44 will move linearly along the axis of the lead screw 43. For example, when the lead screw 43 rotates clockwise, the moving cylinder 44 may move linearly to the right; when the lead screw 43 rotates counterclockwise, the moving cylinder 44 will move linearly to the left.

[0047] During the linear motion of the movable cylinder 44, it drives the fixed plate 45 at its top to move together. The fixed plate 45 is connected to the movable seat 46. Therefore, the movement of the fixed plate 45 is transmitted to the movable seat 46, causing the movable seat 46 to slide above the housing 41. Since the movable seat 46 is connected to the bottom of the side plate 21 and the reinforcing plate 23, the linear motion of the driving component 4 is transmitted to the side plate 21 and the reinforcing plate 23, thereby realizing the position adjustment of the support frame 2.

[0048] like Figure 1 and Figure 2As shown, further, two slide rails 5 are arranged opposite each other on the side of the shell 41 away from the fermentation chamber 1, and two grooves adapted to the slide rails 5 are opened on the inner side of the movable seat 46, and the movable seat 46 slides in cooperation with the slide rails 5.

[0049] When the driving component 4 drives the movable seat 46 to move in a straight line, the cooperation between the slide rail 5 and the groove ensures that the movable seat 46 can only move along the direction set by the slide rail 5, without any deviation or shaking, thereby realizing the positioning of the movement trajectory of the movable seat 46.

[0050] The slide rail 5 not only serves as a guide but also bears the load and provides support. During the movement of the movable seat 46, it is subjected to forces from the side plate 21, the reinforcing plate 23, and its own weight. The slide rail 5, through its contact with the groove of the movable seat 46, disperses and transmits these forces to the housing 41, thereby providing stable support for the movable seat 46. This load-bearing and support function ensures the stability of the movable seat 46 during movement and avoids structural damage or abnormal movement caused by uneven force.

[0051] Meanwhile, the presence of the slide rail 5 provides a stable motion track for the movable seat 46, enabling the movable seat 46 to remain stable during movement, reducing the occurrence of shaking, and improving the motion stability of the entire system.
