[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0031] Reference Figure 1-Figure 3The utility model provides an embodiment of a biological organic fertilizer screening device, including a frame 1, which is used to support the entire device structure, a shell 2 is fixedly connected to the inside of the frame 1, and the shell 2 is used to wrap and protect the internal structure. A feeding pipe 3 is fixedly connected to the top of the frame 1, and the feeding pipe 3 is used to feed fertilizer into the screening drum 4. One end of the feeding pipe 3 is fixedly connected to a limiting plate 10, and the limiting plate 10 is used to limit the grille drum 11 to prevent it from deflecting. The grille drum 11 is rotatably connected to the inside of the limiting plate 10, and the grille drum 11 is used for the preliminary screening of fertilizers. The outer wall of the grille drum 11 is fixedly connected to a rubber plate 13, and the rubber plate 13 drives the grille drum 11 to rotate by contacting the screening drum 4. A motor 7 is fixedly connected to the top of the frame 1, and the motor 7 is used to provide power to drive the screening drum 4 to rotate, and the cylinder wall of the screening drum 4 is moved according to the distance. Fine holes 5 and coarse holes 6 are sequentially provided in the direction away from the feeding pipe, which are respectively used to screen fertilizers of different particle sizes. A baffle 12 is evenly fixedly connected to the circumferential side of the interior of the screening drum 4. The baffle 12 is used to control the flow direction of the fertilizer. A discharge port 14 and a discharge port 2 15 are provided inside the shell 2. The discharge port 14 and the discharge port 2 15 are respectively used to output fertilizers of different screening grades. The grille drum 11 and the limit plate 10 are rotatably connected at one end close to each other with a connecting block 16. The connecting block 16 is used to connect and support the grille drum 11. A limiting assembly is provided between the two connecting blocks 16. The limiting assembly is used to prevent the grille drum 11 from excessive rotation. The limiting assembly includes a telescopic rod 17 and a tension spring 18. The tension spring 18 is used to apply tension to the telescopic rod 17 to prevent the grille drum 11 from being displaced due to excessive force.
[0032] Specifically, when screening the fertilizer, first put the fertilizer into the feeding pipe 3, the output end of the motor 7 starts to work, driving the screening drum 4 to rotate along the predetermined track, and the screening drum 4 is firmly embedded in the limiting groove 9 through the limiting wheel 8 on the frame 1, and performs precise rotation under the restriction of the limiting plate 10, ensuring that the operation of the screening drum 4 is smooth and controlled. When the screening drum 4 rotates, the internal baffle 12 begins to come into contact with the rubber plate 13, thereby driving the grid drum 11 to rotate synchronously. In order to make the screening process smoother, the grid drum 11 is connected to the extension block 16 through the connecting block 16. The retracted rod 17 is connected and is subjected to the tension of the tension spring 18, which not only effectively prevents the grille drum 11 from excessive rotation due to external force during the screening process, but also increases the shaking frequency of the grille drum 11, so that the fertilizer can be more evenly distributed and screened. As the screening drum 4 continues to rotate, fertilizer particles of different sizes are screened out through the sieves of fine holes 5 and coarse holes 6 respectively. Small particles fall into the discharge port 15 through the fine holes 5, and large particles enter the discharge port 14 through the coarse holes 6 and are discharged. The whole process effectively avoids the accumulation of fertilizer during screening and improves the screening efficiency.
[0033] Reference Figure 4, limiting grooves 1 9 are provided at both ends of the circumferential side of the screening drum 4, and limiting grooves 1 9 are used to guide the rotation direction of the screening drum 4. Two pairs of limiting wheels 8 are rotatably connected to the top of the frame 1, and the limiting wheels 8 are used to support and guide the stable operation of the screening drum 4 during the screening process. Each pair of limiting wheels 8 is slidably connected inside the limiting groove 1 9 to ensure that the screening drum 4 does not deviate during the rotation process. A fixed rod 19 is fixedly connected inside the shell 2, and the fixed rod 19 is used to support the internal moving structure. A limiting groove 2 20 is provided inside the fixed rod 19, and the limiting groove 20 is used to limit the sliding range of the telescopic rod 25. A limiting groove 3 21 is provided inside the frame 1, and the limiting groove 3 21 is used for the sliding limit of the slide 22. A slide 22 is slidably connected inside the frame 1, and the slide 22 is used to drive the bristles 24 to move on the outer wall of the screening drum 4 to ensure that the outer wall of the screening drum 4 is clean. The outer wall of the skateboard 22 is fixedly connected to the limit block 23, and the limit block 23 is used to ensure that the skateboard 22 slides stably in the limit groove three 21 without deviation. A brush 24 is fixedly connected to one side of the skateboard 22, and the bristles 24 are close to the outer wall of the screening cylinder 4 to ensure that the bristles 24 can clean the outer wall of the screening cylinder 4 during the screening process to prevent clogging of the pores. A telescopic rod 25 is provided inside the fixed rod 19, and the telescopic rod 25 is used to drive the skateboard 22 to slide. A compression spring 26 is provided on the outer wall of the telescopic rod 25, and the compression spring 26 is used to provide elastic force to ensure that the skateboard 22 always clings to the outer wall of the screening cylinder 4 during the screening process and maintains the pressure of the bristles 24. One end of the telescopic rod 25 and the compression spring 26 are fixedly assembled with the skateboard 22 to ensure the stability of the skateboard 22 and the bristles 24. The other ends of the telescopic rod 25 and the compression spring 26 are fixedly connected to the inside of the fixed rod 19 to provide stable elastic support;
[0034] Specifically, during the rotation of the screening drum 4, the bristles 24 on the shell 2 also work synchronously, continuously sweeping and brushing the outer surface of the screening drum 4 to prevent the fine pores 5 and coarse pores 6 on the screening drum 4 from being blocked by debris or fertilizer, ensuring a smooth screening process. The bristles 24 are fixed in the fixed rod 19 through the structure of the slide plate 22, and are slid and limited under the drive of the slide plate 22, so that the bristles 24 always remain on the outer surface of the screening drum 4 for cleaning. The slide plate 22 is embedded in the limiting groove 3 21 under the action of the limiting block 23, ensuring the stability of the sliding process, and through the cooperation of the limiting structure, the bristles 24 can be closely attached to the screening drum 4 during the rotation process. At the same time, the tension of the compression spring 26 further ensures that the bristles 24 always apply appropriate pressure and are close to the outer wall of the screening drum 4, thereby effectively performing the cleaning work, ensuring that the fine pores 5 and coarse pores 6 remain unobstructed, avoiding blockage, and improving the overall working efficiency and screening accuracy of the equipment.
[0035] Working principle: When using the bio-organic fertilizer screening equipment, first, when screening the fertilizer, put the fertilizer into the feeding pipe 3, and then the output end of the motor 7 drives the screening drum 4 to rotate. The screening drum 4 is embedded in the limiting groove 9 and rotates in the limiting plate 10 through the limiting wheel 8 on the frame 1 to limit the position. Then, when the screening drum 4 rotates, the internal baffle 12 contacts the rubber plate 13 to drive the grille drum 11 to rotate. At the same time, the grille drum 11 is connected to the limiting plate 10 through the connecting block 16 and the telescopic rod 17 to the upper limit position, and the tension of the tension spring 18 is used to prevent the grille drum 11 from excessive rotation when the force is applied through the rubber plate 13, and it can also improve the grille drum 1 1, and then the fertilizer falls into the screening drum 4. Through the rotation of the screening drum 4, fertilizers of different sizes are screened through the fine holes 5 and the coarse holes 6 and fall into the discharge port 2 15 and the discharge port 1 14 respectively for discharge, thereby achieving the effect of preventing fertilizer accumulation. Subsequently, while the screening drum 4 rotates, the bristles 24 on the shell 2 continuously sweep the screening drum 4 to prevent the fine holes 5 and the coarse holes 6 on the screening drum 4 from being blocked. The bristles 24 are fixed to the fixed rod 19 by the slide plate 22 for sliding limitation. The slide plate 22 is limited in the limiting groove 3 21 by the limiting block 23, and the bristles 24 are always attached to the outer wall of the screening drum 4 for cleaning through the tension of the compression spring 26.
