[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: an automatic fertilizer powder feeding device, including a body 1, with a feeding hopper 2 fixedly connected to the top of the body 1. The feeding hopper 2 is used to feed fertilizer into the body 1, allowing the body 1 to transport the fertilizer inside the feeding hopper 2 to the processing device. An installation groove 3 is provided inside the feeding hopper 2, and a screen 4 is slidably connected inside the installation groove 3, providing installation space for the screen 4. The screen 4 is used to sieve the fertilizer powder. A cleaning brush 5 is slidably connected inside the screen 4 for cleaning... The clumps of debris inside the screen 4 are crushed and cleaned, resulting in high feed uniformity. Two connecting rods 9 are fixedly connected to the front end of the cleaning brush 5, and a slider 8 is fixedly connected to the front end of the connecting rods 9. The slider 8 is used to pull the cleaning brush 5 forward through the connecting rods 9. There are locking blocks 7 slidably connected to both sides of the slider 8. Two slots 6 are opened in the inner wall of the screen 4. The locking blocks 7 are engaged in the slots 6, so that the locking blocks 7 can limit the slider 8, thereby making the cleaning brush 5 more stable to install.

[0025] When fertilizer powder needs to be fed into the processing device, the screen 4 is slid into the hopper 2 to screen the fertilizer powder. At this time, the two locking blocks 7 are moved inward to slide into the slider 8, so that the locking blocks 7 no longer limit the slider 8. Then, by pulling the slider 8, the slider 8 drives the connecting rod 9 to move forward, so that the connecting rod 9 pulls the cleaning brush 5 to squeeze and break up the clumps of fertilizer inside the screen 4 and clean the holes in the inner wall of the screen 4. This makes the fertilizer entering the machine body 1 more uniform, resulting in better post-processing quality and better economic efficiency.

[0026] Example 2: Based on Example 1, to facilitate the pulling of the locking block 7, two limiting grooves 14 are provided inside the slider 8. The locking block 7 is slidably connected inside the limiting grooves 14, which provide installation space for the locking block 7. A limiting piece 15 is fixedly connected to the end of the locking block 7 away from the locking groove 6. The limiting piece 15 is slidably connected inside the limiting groove 14, which limits the limiting piece 15, allowing it to slide smoothly. A pull rope 17 is fixedly connected to the end of the limiting piece 15 away from the locking groove 6. 7 is slidably connected inside the limiting groove 14. The limiting groove 14 limits the pull rope 17 so that the pull rope 17 will not deviate when sliding. The end of the pull rope 17 away from the limiting piece 15 is fixedly connected to the pull block 18. The pull block 18 is slidably connected to the front side of the slider 8. The slider 8 limits the pull block 18 so that the pull block 18 can slide smoothly. An elastic element 2 16 is sleeved on the outside of the pull rope 17. One end of the elastic element 2 16 is fixedly connected to the limiting piece 15, and the other end of the elastic element 2 16 is fixedly connected to the inner wall of the limiting groove 14.

[0027] When the locking block 7 needs to be pulled, by moving the two pulling blocks 18 to a closer side, the pulling blocks 18 can pull the pulling rope 17 to move inward, which in turn can pull the limiting piece 15 to compress the elastic element 16 and cause deformation, so that the limiting piece 15 can pull the locking block 7 to slide into the interior of the limiting groove 14. Conversely, by releasing the pulling blocks 18, the elastic element 16 can perform a reset movement, which in turn can push the limiting piece 15 to move outward, so that the limiting piece 15 can push the locking block 7 to engage with the interior of the locking groove 6.

[0028] Example 3: Based on Example 2, in order to improve the cleaning effect on the screen 4, the cleaning brush 5 has multiple placement grooves 10 inside. An elastic element 11 is fixedly connected to the upper side of the inner wall of the placement groove 10. An extrusion plate 12 is fixedly connected to the bottom end of the elastic element 11. The extrusion plate 12 is slidably connected inside the placement groove 10. The placement groove 10 limits the extrusion plate 12 so that the extrusion plate 12 will not deviate when sliding. A striking rod 13 is fixedly connected to the bottom end of the extrusion plate 12. The striking rod 13 is slidably connected inside the placement groove 10. The placement groove 10 limits the striking rod 13 so that the striking rod 13 can slide smoothly. The end of the striking rod 13 away from the extrusion plate 12 is an arc block structure and slides against the inner wall of the screen 4, so that the striking rod 13 can easily slide into the through hole of the screen 4 and detach from it.

[0029] As the cleaning brush 5 moves, the striking rod 13 slides on the surface of the screen 4. When the striking rod 13 is perpendicular to the holes of the screen 4, the elastic element 11 returns to its original position, which in turn pushes the extrusion plate 12 downward. The extrusion plate 12 then pushes the striking rod 13 downward, allowing the striking rod 13 to enter the holes of the screen 4 and strike them. This causes the fertilizer powder blocking the screen 4 to vibrate and fall off. As the cleaning brush 5 continues to move, the arc of the striking rod 13 slides against the holes of the screen 4 and disengages from them. It then slides on the inner wall of the screen 4 and pushes the extrusion plate 12 upward, causing the extrusion plate 12 to deform the elastic element 11 in preparation for the next strike.

[0030] The working process of this utility model is as follows:

[0031] When fertilizer powder needs to be fed into the processing device, the screen 4 is slid into the hopper 2 to sieve the fertilizer powder. At this time, by moving the two pull blocks 18 to a similar side, the pull blocks 18 pull the pull rope 17 inward, causing the pull rope 17 to pull the limiting plate 15 to compress the elastic element 16, causing deformation. The limiting plate 15 then pulls the locking block 7 into the limiting groove 14. At this time, by pulling the slider 8, the slider 8 drives the connecting rod 9 forward, causing the connecting rod 9 to pull the cleaning brush 5 to crush the clumps of fertilizer inside the screen 4. While the cleaning brush 5 is moving, the striking rod 13 slides on the surface of the screen 4. When the striking rod 13 is perpendicular to the holes in the screen 4, the elastic element 11 returns to its original position, pushing the extrusion plate 12 downward, causing the extrusion plate... The 12 pushes the striking rod 13 downward, allowing it to enter the holes of the screen 4 and strike them. This vibrates the fertilizer powder blocking the screen 4, causing it to fall off. As the cleaning brush 5 continues to move, the arc of the striking rod 13 slides against the holes of the screen 4 and disengages from them. It then slides on the inner wall of the screen 4, pushing the extrusion plate 12 upward. This causes the extrusion plate 12 to compress the elastic element 11, deforming it in preparation for the next strike. After cleaning, the slider 8 is pushed back to its original position, and the pull block 18 is released, allowing the elastic element 16 to reset. This causes the elastic element 16 to push the limiting plate 15 outward, allowing the limiting plate 15 to push the locking block 7 into the slot 6. This ensures that the fertilizer entering the machine body 1 is more uniform, resulting in better post-processing quality and improved economic efficiency.
