Description

Technical Field

[0001] This utility model relates to the field of biological fertilizer screening technology, specifically a screening device for biological fertilizer processing and manufacturing. Background Technology

[0002] As a green input in modern agriculture, bio-fertilizers have the core function of improving soil structure, increasing fertilizer utilization, and enhancing crop resistance through microbial metabolic activities. However, the efficiency and quality of the screening process in the production of bio-fertilizers directly determine the final performance of the product, and its importance is reflected in the three dimensions of technology, economy, and ecology.

[0003] However, when using some existing screening devices, the conventional open-feeding method can easily cause external dust and other impurities to enter the inner cavity of the screening device, thereby contaminating the bio-fertilizer, reducing the product qualification rate, and the bio-fertilizer dust generated during the screening process can easily drift outwards, not only polluting the workshop environment, but also threatening the health of the staff.

[0004] In addition, some existing screening devices are prone to forming piles or clumps during the feeding process. These piles and clumps can hinder the uniform distribution of bio-fertilizers in the screening device, causing some fertilizers to not be fully screened, thus affecting the screening effect and reducing the yield of qualified products.

[0015] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0016] Please see Figure 1-4As shown, a screening device for processing bio-fertilizer includes a screening mechanism 1, which consists of a base, a discharge port, and other structures for easy operation. A connecting shell 2 is fixedly connected to the top opening of the screening mechanism 1, and a mounting shell 3 is fixedly connected to the top opening of the connecting shell 2. A guide shell 4 is fixedly connected to the top opening of the mounting shell 3. The guide shell 4 is a hollow frustum shape, allowing the bio-fertilizer poured in to naturally converge towards the center, providing the necessary conditions for subsequent screening. A torsion spring mechanism 5 is installed on the inner wall of the mounting shell 3. When the bio-fertilizer is poured down from the guide shell 4, the torsion spring mechanism 5 adjusts its opening and closing degree according to the weight or impact force of the bio-fertilizer, allowing it to smoothly enter the inner cavity of the screening mechanism 1. Furthermore, since the torsion spring mechanism 5 automatically closes to form a barrier when there is no pressure, it effectively reduces the entry of external dust and other impurities into the screening mechanism 1 during non-feeding periods, preventing contamination of the bio-fertilizer to be processed. Meanwhile, it also reduces the amount of residual bio-fertilizer dust that may escape from the screening mechanism 1, thereby maintaining the cleanliness of the working environment and improving the comfort of the staff. The inner wall of the mounting shell 3 is fixedly connected with two blocks 6, which are symmetrical with the center line of the mounting shell 3. The blocks 6 work in conjunction with the torsion spring mechanism 5. Under this action, the movement stroke of the torsion spring mechanism 5 can be limited within a certain range, effectively reducing the possibility of the torsion spring mechanism 5 being damaged due to excessive deformation exceeding its elastic limit. This ensures that the torsion spring mechanism 5 can work stably for a long time. The inner wall of the connecting shell 2 is fixedly connected with a connecting frame 7. The surface of the connecting frame 7 is provided with a rotating mechanism 8. The rotating mechanism 8 can move the poured bio-fertilizer, so that the bio-fertilizer that was originally concentrated in one place can be dispersed to the surrounding area. This allows for more even screening of the inner cavity of the screening mechanism 1, effectively reducing the situation of insufficient screening due to fertilizer accumulation and improving the working efficiency and screening quality of the entire screening device.

[0017] The torsion spring mechanism 5 includes a connecting rod 51 fixedly connected to the inner wall of the mounting shell 3. One end of the connecting rod 51 is fixedly connected to a connecting plate 52. There are two connecting plates 52, symmetrically positioned with respect to the center line of the mounting shell 3. The diameter of the connecting plates 52 is smaller than the inner diameter of the mounting shell 3 for ease of use. The connecting plates 52 cooperate with the stop block 6. A torsion spring 53 is fixedly connected to the inner wall of the mounting shell 3. One end of the torsion spring 53 is fixedly connected to the inner wall of the connecting plate 52. There are four torsion springs 53 and four connecting rods 51, arranged in pairs and symmetrically positioned with respect to the center line of the mounting shell 3. Under this action, when the bio-fertilizer is poured downwards from the guide shell 4 into the screening mechanism 1... The bio-fertilizer impacts the connecting plate 52. As the weight of the bio-fertilizer increases, the pressure on the connecting plate 52 gradually increases. This pressure overcomes the elasticity of the torsion spring 53, causing the torsion spring 53 to deform elastically. This causes the connecting plate 52 to gradually open, allowing the bio-fertilizer to pass through for subsequent screening. When there is no pressure, the connecting plate 52 automatically closes, effectively reducing the possibility of external dust and other impurities entering the inner cavity of the screening mechanism 1 and contaminating the bio-fertilizer to be processed. It also reduces the possibility of bio-fertilizer dust escaping from inside the screening mechanism 1 during use, thus maintaining a clean working environment and providing a comfortable operating environment for the staff.

[0018] The rotating mechanism 8 includes a protective shell 81 fixedly connected to the surface of the connecting frame 7. A servo motor 82 is installed inside the protective shell 81. The output shaft of the servo motor 82 is rotatably connected to the inner wall of the protective shell 81. A rotating disk 83 is fixedly connected to the output shaft of the servo motor 82. Under this action, the servo motor 82 is turned on to drive the rotating disk 83 to rotate at high speed, which can generate a strong pushing effect on the bio-fertilizer poured in from the guide shell 4. The centrifugal force generated by its rotation can disperse the bio-fertilizer particles in all directions, breaking up the accumulation and clumps that may be formed during the pouring process. This allows the bio-fertilizer to enter the inner cavity of the screening mechanism 1 in a looser and more uniform state, effectively reducing the situation of insufficient screening caused by fertilizer accumulation in the screening mechanism 1, thereby enhancing the screening effect and significantly improving the yield of qualified products.

[0019] It is worth noting that the technical features such as the screening mechanism 1 proposed in this technical solution should be considered as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be achieved using conventional methods in this field, and this technical solution will not elaborate further. Working principle: The operator pours the bio-fertilizer into the guide shell 4. After entering the mounting shell 3, the bio-fertilizer impacts the connecting plate 52. As the weight of the bio-fertilizer increases, the pressure on the connecting plate 52 gradually increases. When the pressure overcomes the elastic force of the torsion spring 53, the torsion spring 53 undergoes elastic deformation, causing the connecting plate 52 to gradually open, allowing the bio-fertilizer to pass through and enter the inner cavity of the screening mechanism 1. When the pouring stops, the pressure on the connecting plate 52 disappears, and the torsion spring 53 returns to its elastic force, causing the connecting plate 52 to automatically close. This process ensures that the bio-fertilizer enters smoothly during feeding and effectively reduces the entry of external dust and other impurities into the screening mechanism 1 during non-feeding periods, thus preventing contamination. The subsequent handling of bio-fertilizer also reduces the amount of bio-fertilizer dust escaping from the screening mechanism 1, thus maintaining the cleanliness of the working environment. When the bio-fertilizer passes through the connecting shell 2, the servo motor 82 inside the protective shell 81 drives the rotating disk 83 to rotate at high speed, causing the rotating disk 83 to exert a strong pushing effect on the bio-fertilizer. The centrifugal force generated by its rotation disperses the bio-fertilizer particles in all directions, breaking up any accumulation and clumps that may form during the pouring process. This allows the bio-fertilizer to enter the inner cavity of the screening mechanism 1 in a looser and more uniform state, effectively reducing the situation of insufficient screening caused by fertilizer accumulation, thereby enhancing the screening effect and increasing the yield of qualified products.
