Description

Technical Field

[0001] The utility model relates to a circulation screening device, in particular to a circulation screening device for producing water-soluble fertilizers. Background Art

[0002] Water-soluble fertilizers are completely soluble in water and are suitable for application through modern irrigation methods such as sprinkler and drip irrigation. They are quickly absorbed by crops. They typically contain macronutrients such as nitrogen, phosphorus, and potassium, as well as trace elements such as zinc, iron, and boron, necessary for plant growth, providing comprehensive nutrition for crops:

[0003] Ordinary screening devices usually only have a single-layer screen or a simple structural design, which causes fertilizer particles to easily accumulate or clog, affecting the screening efficiency. Especially for large-scale production, the working speed will be significantly reduced, and it is impossible to accurately separate according to particle size. It is easy for oversized particles to remain in the finished product, affecting the use effect of the fertilizer.

[0004] It should be noted that the above content falls within the technical cognition of the utility model applicant and does not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a circulating screening device for the production of water-soluble fertilizers.

[0006] To achieve the above-mentioned purpose, the utility model proposes a circulating screening device for producing water-soluble fertilizers, comprising a chassis:

[0007] Four support plates are evenly fixed at the edge of the chassis, and two symmetrical support plates are fixed with sliding rods at the top, and the outer walls of the two sliding rods are connected with the corresponding through plates, and the two through plates are fixed on both sides of the top plate, and four placement holes are symmetrically opened on the top plate, and a screen is fixed inside each of the placement holes. A rotating shaft is provided at the top of the top plate for rotation, and the outer wall of the rotating shaft is fixedly connected to one end of the retaining ring, and support seats are fixed on both sides of the bottom end of the top plate, and a driving motor is fixed on the inner side of the two support seats, and the output end of the driving motor is fixedly connected to one side of the corresponding counterweight through the corresponding support seat.

[0008] In one example, a servo motor is fixedly provided at the middle position of the bottom end of the top plate, and the output end of the servo motor is fixedly connected to the bottom end of the rotating shaft.

[0009] In one example, the apertures of the four sieves become larger in sequence.

[0010] In one example, four receiving frames are fixedly provided on the top of the chassis, and the four receiving frames are located at the bottom of the corresponding screening meshes.

[0011] In one example, the outer walls of the two sliding rods are provided with springs, the bottom ends of the two springs are in contact with the top ends of the corresponding support plates, the top ends of the two springs are in contact with the bottom ends of the through plates, and the top ends of the two sliding rods are fixed with limit blocks.

[0012] In one example, a supporting leg is fixedly provided at the bottom end of each of the supporting plates, and a supporting plate is fixedly provided at the bottom ends of the four supporting legs.

[0013] The circulating screening device for producing water-soluble fertilizers proposed by the utility model can bring the following beneficial effects:

[0014] The utility model places the water-soluble fertilizer inside the retaining ring through the chassis, support plate, through plate, slide rod, limit block, top plate, spring, retaining ring, receiving frame, servo motor, drive motor, support seat, counterweight block and screening mesh.

[0026] like Figures 1 to 4 As shown, the embodiment of the present utility model provides a circulating screening device for producing water-soluble fertilizers, including a chassis 1:

[0027] Four support plates 2 are evenly fixed at the edge of the chassis 1, and two symmetrical support plates 2 are fixed with sliding rods 4 on the top ends, and the outer walls of the two sliding rods 4 are connected with the corresponding through plates 3 through-interlaced, and the two through plates 3 are fixed on both sides of the top plate 6. Four placement holes are symmetrically opened on the top plate 6, and a screen 16 is fixed inside each placement hole. A rotating shaft 7 is provided at the top end of the top plate 6, and the outer wall of the rotating shaft 7 is fixedly connected to one end of the retaining ring 8. Support seats 12 are fixed on both sides of the bottom end of the top plate 6, and a driving motor 11 is fixed on the inner side of the two support seats 12. The output end of the driving motor 11 passes through the corresponding support seat 12 and is fixedly connected to one side of the corresponding counterweight block 13.

[0028] Specifically, a servo motor 10 is fixedly provided at the middle position of the bottom end of the top plate 6 , and the output end of the servo motor 10 is fixedly connected to the bottom end of the rotating shaft 7 .

[0029] Specifically, the apertures of the four sieves 16 become larger in sequence.

[0030] Specifically, four receiving frames 9 are fixedly provided on the top of the chassis 1 , and the four receiving frames 9 are located at the bottom of the corresponding screening meshes 16 .

[0031] Specifically, the outer walls of the two sliding rods 4 are provided with springs 17, the bottom ends of the two springs 17 are in contact with the top ends of the corresponding support plates 2, the top ends of the two springs 17 are in contact with the bottom of the through plate 3, and the top ends of the two sliding rods 4 are fixed with limit blocks 5.

[0032] Specifically, a support leg 14 is fixedly provided at the bottom end of each support plate 2 , and a support plate 15 is fixedly provided at the bottom end of the four support legs 14 .

[0033] Working Principle: First, water-soluble fertilizer is placed inside retaining ring 8, ensuring it is evenly distributed within the ring. When the device is started, drive motor 11 begins operating, driving counterweight 13 to rotate and vibrate synchronously with top plate 6. The rotation of counterweight 13 by drive motor 11 causes the entire top plate 6 to vibrate. Simultaneously, servo motor 10 rotates shaft 7, causing retaining ring 8 to move at a steady speed to the four screens 16 above top plate 6. Each screen 16 has a larger aperture, separating and screening the fertilizer by particle size. As retaining ring 8 rotates over each screen 16, the fertilizer gradually falls due to vibration. The smallest fertilizer particles first pass through the first screen 16 with the smallest aperture, while the remaining larger particles continue to move with retaining ring 8 to the next larger screen 16. This cycle continues, and the fertilizer is gradually graded and screened by particle size through the four screens 16 on top plate 6. Each screen 16 has a corresponding receiving frame 9 below it. The fertilizer particles separated by different screens will fall into the corresponding receiving frames 9. The screened fertilizers are classified and stored according to different particle sizes. The larger particles will be screened out at the last screen 16. The rotation of the two counterweights 13 causes the top plate 6 to vibrate. This vibration is transmitted to the screen part of the entire device through the elastic force of the slide rod 4 and the spring 17, effectively preventing the screen from being blocked during the screening process, ensuring that the fertilizer can pass through the screen 16 quickly, and improving the screening efficiency. The chassis 1 of the device provides stable support through the support plate 2 and the support legs 14. The support plate 15 further enhances the stability of the equipment during operation, ensuring that the screening process proceeds smoothly. The device stops working, and the fertilizer particles of different particle sizes screened out have fallen into the corresponding receiving frames 9. The staff can check the receiving frames 9 and unload the fertilizer particles separately for the next processing or packaging.

[0034] The various embodiments in this specification are described in a progressive manner. Similar parts between the various embodiments can be referred to in conjunction with each other. Each embodiment focuses on the differences between the other embodiments. In particular, the system embodiments are described briefly because they are generally similar to the method embodiments.
