Description

Technical Field

[0001] This utility model belongs to the field of organic fertilizer technology, and in particular relates to a device for the harmless preparation of functional microbial organic fertilizer. Background Technology

[0002] Driven by both green agricultural development and ecological environmental protection, functional microbial organic fertilizers have become a core material to replace chemical fertilizers due to their multiple functions, including soil improvement, nutrient supply, and disease control. Their preparation process requires organic waste such as livestock and poultry manure, straw, and kitchen waste as raw materials, and resource utilization is achieved through processes such as raw material pretreatment, microbial inoculation, and mixed fermentation.

[0003] Existing preparation devices cannot effectively break down large pieces of straw, fibrous impurities, and dense clumps in organic waste raw materials. Pathogens and weed seeds can easily hide inside the raw materials, making it difficult for microorganisms to penetrate during subsequent fermentation. This results in incomplete sterilization and uneven fermentation, and the finished product is prone to residual harmful substances, failing to meet the harmlessness standard. At the same time, the contact area between large raw materials and functional microbial agents is limited, and the agents can only adhere to the surface and have difficulty penetrating. In addition, raw materials of different densities are prone to stratification, and even after stirring, they are still unevenly mixed, resulting in an unbalanced distribution of microbial activity and a significant reduction in fermentation efficiency.

[0004] To address these issues, we provide a device for the harmless preparation of functional microbial organic fertilizer. Utility Model Content

[0005] The purpose of this invention is to provide a functional microbial organic fertilizer harmless preparation device. By combining the cutting component and the stirring component, it solves the problem in the prior art that the large pieces of straw, fiber impurities and dense clumps in the organic waste raw materials cannot be effectively broken, resulting in incomplete sterilization and uneven fermentation, and a significant reduction in fermentation efficiency.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a device for the harmless preparation of functional microbial organic fertilizer, comprising a box body with a feed hole at the top and a cutting assembly on one side of the box body. The cutting assembly includes a cutting box, one side of which is fixedly connected to the box body. A baffle is fixedly connected to the top of the cutting box, and a discharge pipe is fixedly connected to the bottom of the cutting box, communicating with the box body. Two rotating rods are movably connected to one side of the inner cavity of the cutting box via bearings. First teeth are fixedly connected to the surface of the rotating rods and are equidistantly spaced. Second teeth are fixedly connected to one side of the inner cavity of the cutting box and are also equidistantly spaced. The cutting box has a rectangular cavity structure, and its side near the box body is rigidly fixed to the side wall of the box body by full welding. The discharge pipe communicates with the box body to form a seamless material channel, ensuring that the cut raw materials can be directly transported into the inner cavity of the box body, avoiding spillage or secondary contamination. The baffle prevents material leakage. The two rotating rods are horizontally parallel. The rotating rods are symmetrically mounted on the side walls of the cutting box cavity via bearings. Both ends of the rotating rods are interference-fitted with the inner rings of the bearings to ensure no offset or jamming during rotation. The first set of teeth on the rotating rod surface are evenly distributed, and the first set of teeth on the two rotating rods interlock, forming the first shearing surface during rotation. Second set of teeth, matching the first set of teeth, are fixed on the side walls of the cutting box cavity. These second set of teeth are also evenly distributed, and the distance between their tips is consistent with the first set of teeth, forming the second shearing surface. When the raw material enters the cutting box through the feed guide groove, the two rotating rods rotate synchronously in opposite directions, causing the first and second set of teeth to interact and perform double shearing and crushing of the raw material. This thoroughly breaks down large clumps and fibrous structures, and ensures that the crushed raw material particles are of uniform size, providing a good foundation for the uniform penetration and efficient fermentation of subsequent microbial agents. At the same time, the uniform particle shape also reduces resistance during subsequent stirring, improving overall production efficiency.

[0008] This invention is further configured such that a stirring assembly is provided on the top of the box, the stirring assembly includes a connecting pipe, the bottom of the connecting pipe is connected to the box, a connecting block is provided in the inner cavity of the box, a sleeve is fitted on the surface of the connecting block, a slider is fixedly connected to the surface of the sleeve, one side of the slider is slidably connected to the connecting pipe through a groove, the connecting pipe is vertically fixed at the center position of the top of the box, providing a stable installation reference for the entire stirring assembly, ensuring that the structure does not shift or shake during the stirring process, the connecting block and the sleeve can form a tight transmission fit, stably transmitting rotational power, driving the sleeve to rotate synchronously, the slider is adapted to the groove on the inner wall of the connecting pipe, the guiding effect of the groove allows the sleeve to move smoothly along the groove while rotating, realizing three-dimensional coverage of the stirring range, allowing the stirring range to cover the entire area of ​​the box, effectively eliminating stirring dead corners, and creating good conditions for the uniform penetration of subsequent microbial agents.

[0009] The present invention is further configured such that a first power mechanism is provided on one side of the cutting box. The first power mechanism includes a first housing, and there are two first housings. A first motor is fixedly connected to one side of the inner cavity of the first housing. A first pulley is fixedly connected to the output end of the first motor. A second pulley is connected to one side of the first pulley via belt drive. One side of the second pulley is fixedly connected to the rotating rod. The first pulley at the output end of the first motor is connected to the second pulley via belt drive. The elastic characteristics of belt drive can absorb the vibration of the motor during operation, avoid the speed fluctuation caused by rigid transmission, and ensure that the rotating rod rotates at a uniform speed. The two first motors drive one rotating rod independently, which can flexibly adjust the rotation direction and speed of the rotating rod, so that the first teeth on the two rotating rods form an efficient shearing cooperation, improving the cutting efficiency and precision.

[0010] The present invention is further configured such that a stirring shaft is fixedly connected to the bottom of the sleeve, and blades are sleeved on the surface of the stirring shaft. The blades are equidistant from each other, and the stirring shaft can rotate and move synchronously with the sleeve to ensure the transmission of stirring power. The blades are equidistantly distributed along the axial direction, and the installation angles of adjacent blades are staggered to form an all-round stirring coverage. The structural design of the blades is adapted to the material characteristics of organic waste, and can generate strong stirring force during rotation to break up the clumps of raw materials, while promoting the raw materials to form a circulation flow in the box and promoting the mixing of raw materials in different areas.

[0011] The present invention is further configured such that a second power mechanism is provided at the top of the connecting pipe. The second power mechanism includes a second housing, a second motor is fixedly connected to the top of the inner cavity of the second housing, a third pulley is fixedly connected to the output end of the second motor, a fourth pulley is connected to one side of the third pulley via belt drive, a connecting rod is fixedly connected to the bottom of the fourth pulley, the bottom of the connecting rod passes through the inner cavity of the connecting pipe and is fixedly connected to the connecting block. The second motor, as the power source of the stirring assembly, can provide continuous and stable power output, adapting to the needs of long-term continuous stirring. The second motor forms an efficient transmission through the third pulley, belt and fourth pulley. The connecting rod passes through the bottom of the housing and is fixedly connected to the connecting block, which can transmit the rotational power of the motor to the connecting block, thereby driving the sleeve, stirring shaft and blades to complete the compound stirring action, ensuring the efficient operation of the stirring assembly.

[0012] The present invention is further configured such that a discharge plate is fixedly connected to the bottom of the box, and a limiting plate is fitted inside the discharge plate. The discharge plate is fixed to the bottom of the box to form an inclined discharge channel. The discharge is assisted by the gravity of the raw materials themselves, so that the fermented organic fertilizer can flow out smoothly and avoid accumulation and blockage. The limiting plate is fitted inside the discharge plate and forms a sliding fit with the discharge plate. The opening and closing of the discharge channel can be controlled by removing the limiting plate.

The stabilizing rings are equidistantly fitted along the surface of the box and fixed to the box by welding, which can enhance the rigidity and deformation resistance of the box itself and avoid the box from twisting due to vibration generated during stirring and cutting. The fixing plates at the top of the stabilizing rings are equidistantly distributed in the horizontal direction, and their two ends are fixedly connected to adjacent stabilizing rings to form a tie structure, connecting the various stabilizing rings into a whole, further improving the overall stability of the box. The fixing frame at the bottom of the stabilizing rings extends vertically downward and is rigidly fixed to the stabilizing rings, so as to evenly transfer the weight of the box to the support surface and avoid excessive local stress that could cause the equipment to tilt.

[0014] The present invention is further provided that the bottom of the fixed frame is fixedly connected with a pad, the pads are equidistant from each other, and the pads are made of wear-resistant and non-slip material, which can increase the friction with the ground, effectively prevent the equipment from shifting due to vibration during operation, and improve the operating stability of the equipment.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses the first and second crushing teeth on the surface of the double rotating rod to form a dynamic shearing synergy structure, which performs double cutting on the raw materials, thoroughly breaking down large fibrous structures, fully exposing pathogens, laying a solid foundation for harmless treatment. The contact area between the uniformly cut raw material particles and the bacterial agent is greatly increased, which can avoid stratification and promote the penetration of the bacterial agent, ensuring uniform fermentation and stable bacterial activity. At the same time, the fine cutting can reduce the resistance of subsequent stirring, reduce energy consumption and equipment failure risk, and shorten the fermentation cycle to adapt to large-scale production.

[0017] 2. This utility model uses a connecting block to drive the sleeve to rotate. During the rotation of the sleeve, the slider can open an arc groove along the inner cavity of the connecting pipe to guide the sleeve to move up and down, while realizing three-dimensional coverage of the stirring range. This composite stirring method can completely break down the layering barrier of raw materials, fully stir the upper light raw materials and the lower heavy raw materials, and make the functional microbial agent evenly penetrate into the entire area of ​​the raw materials, ensuring that the fermentation process is uniform and efficient, effectively eliminating stirring dead corners, and reducing the risk of raw material residue and spoilage.

A baffle 22 is welded to its top to prevent material splashing, and the bottom is connected to the inner cavity of the box body 1 via a discharge pipe 23. Two rotating rods 24 are arranged parallel to each other inside the cutting box 21, with both ends of the rods 24 connected to the box wall via deep groove ball bearings. Each rotating rod 24 has several first crushing teeth 25 welded equidistantly on its surface, and the first crushing teeth 25 on the two rotating rods 24 are arranged in a staggered pattern. Second crushing teeth 26, which cooperate with the first crushing teeth 25, are fixedly installed on the inner wall of the cutting box 21. When the rotating rods 24 rotate, the first crushing teeth 25 and the second crushing teeth 26 form a dynamic shearing surface, achieving dual crushing of the raw material.

[0030] The first power mechanism 4 provides power to the cutting assembly 2. (Refer to...) Figure 5 Two first housings 41 are fixed on both sides of the cutting box 21, and each housing a first motor 42. The output shaft of the first motor 42 is connected to the end of the rotating rod 24 via a first pulley 43, a belt, and a second pulley 44, thereby driving the two rotating rods 24 to rotate synchronously in opposite directions.

[0031] The stirring assembly 3 is installed on top of the housing 1. (Refer to...) Figure 2 , Figure 4 and Figure 6 The connecting pipe 31 is vertically fixed to the center of the top of the housing 1, and its inner wall has a vertical groove. The connecting block 32 is connected to the second power mechanism 7 through the connecting rod 75, and a sleeve 33 is fitted on its surface.

[0033] The working principle of this utility model is as follows: S1: Raw Material Crushing: Organic waste raw materials are fed into the cutting box 21 from the top. The first power mechanism 4 is activated, and the two first motors 42 drive the rotating rod 24 to rotate synchronously in opposite directions via belt drive. The first crushing teeth 25 on the rotating rod 24 and the second crushing teeth 26 on the box wall form dynamic shearing, which fully crushes the raw materials. The crushed raw materials enter the box 1 through the discharge pipe 23.

[0034] S2: Stirred Fermentation: The second power mechanism 7 is activated, and the second motor 72 drives the connecting rod 75 to rotate via belt drive, which in turn drives the sleeve 33 and the stirring shaft 5 to rotate. At the same time, with the cooperation of the slider 34 and the chute, the sleeve 33 drives the stirring shaft 5 to move up and down along the connecting pipe 31 axially. This combined rotation and lifting motion allows the blades 6 to cover the entire area inside the box 1, achieving stirring without dead angles and promoting the uniform mixing of microbial agents and raw materials.
