Abstract
Description
Technical Field
[0001] This utility model relates to the field of sieves for fertilizer research and development, specifically a sieve for fertilizer research and development with good screening effect. Background Technology
[0002] Fertilizer research and development is a comprehensive scientific and technological activity aimed at developing more efficient, environmentally friendly fertilizer products that meet the needs of different crops and soils. First, extensive basic research is required to understand the nutrient status of different soil types and the nutrient requirements of crops at different growth stages. Then, formulation design is carried out, and optimal production processes, such as synthesis, fermentation, and granulation, are explored to ensure the stability of the fertilizer's physicochemical properties, such as uniform particle size and good solubility.
[0003] Fertilizer research and development utilizes a wide variety of raw materials, such as phosphate rock, potash, and plant and animal residues. Screening equipment can sift these raw materials, removing impurities, large particles, or portions that do not meet particle size requirements. This ensures the purity and uniformity of the raw materials used in subsequent production, facilitating subsequent chemical reactions and the stability of fertilizer performance. For example, when using organic waste as a raw material, screening equipment can separate impurities such as stones and metals, and sieve excessively large waste particles into suitable sizes for fermentation and other processing. However, in current fertilizer research and development processes, the screens are often fixed directly inside the device, making it difficult for workers to disassemble and reassemble them. This hinders the replacement of screens with different mesh sizes, cleaning, and overall user experience. Utility Model Content

[0025] This utility model provides a technical solution:

[0027] Combination Figures 1 to 5 A screening device for fertilizer research and development with good screening effect includes a screening box 3, a discharge port 31 fixedly connected to the bottom of the screening box 3, a support leg 4 fixedly connected to the bottom of the screening box 3, a screening mechanism 1 set inside the screening box 3, and a fixing mechanism 2 set on the left and right sides of the screening box 3.
[0028] The screening mechanism 1 includes an opening and closing component 11, a connecting component 12, and a screening component 13. The opening and closing component 11 is located on the top of the screening box 3, the connecting component 12 is located on the rear side of the opening and closing component 11, and the screening component 13 is located inside the screening box 3.
[0029] The opening and closing assembly 11 includes a top cover 1101, which is located on the top of the screening box 3. A feed hopper 1102 is fixedly connected to the top of the top cover 1101, and a handle 1103 is fixedly connected to the front side of the top cover 1101. The connecting assembly 12 includes a frame plate 1201, which is fixedly connected to the bottom rear side of the top cover 1101. A rotating cylinder 1202 is fixedly connected to the bottom of the frame plate 1201. A rotating shaft 1203 is rotatably connected to the inner ring of the rotating cylinder 1202. Fixing plates 1204 are fixedly connected to the left and right sides of the rotating shaft 1203. 1204 is fixedly connected to the rear side of the screening box 3. The screening component 13 includes a pad 1301, which is fixedly connected to the screening box 3. A fixing frame 1302 is provided above the pad 1301. The outer side of the fixing frame 1302 fits against the inner ring of the screening box 3. A screen plate 1303 is fixedly connected to the inner ring of the fixing frame 1302. Positioning rods 1304 are snapped into the front and rear sides of the fixing frame 1302. The positioning rods 1304 are fixedly connected to the top of the pad 1301. Handles 1305 are fixedly connected to the four corners of the top of the fixing frame 1302.
[0030] Furthermore: After the operator holds the handle 1103 to flip the top cover 1101, the operator only needs to pull the handle 1305 upwards to disassemble the screen plate 1303, which is convenient for the operator to replace and clean the screen plate 1303. This allows the operator to quickly replace and clean the screen plates 1303 of different mesh sizes as needed, making the device easy to use.
[0031] Example 2
[0032] See Figure 1 , Figure 2 , Figure 3 and Figure 5 Furthermore, based on Embodiment 1, the fixing mechanism 2 includes a positioning component 21 and an outer pulling component 22. The positioning component 21 is disposed on the left and right sides of the screen box 3, and the outer pulling component 22 is disposed on the outside of the positioning component 21.
[0033] The positioning component 21 includes a fixed box 2101, which is fixedly connected to the left and right sides of the screening box 3. A sliding plate 2102 is slidably connected inside the fixed box 2101. A compression spring 2103 is fixedly connected to the outside of the sliding plate 2102. The compression spring 2103 is fixedly connected to the inside and outside of the fixed box 2101. A locking rod 2104 is fixedly connected to the inside of the sliding plate 2102. A sleeve plate 2105 is sleeved on the outer ring of the locking rod 2104. The sleeve plate 2105 is fixedly connected to the top left and right sides of the fixed frame 1302. The external pull component 22 includes a telescopic slide rod 2201, which is fixedly connected to the outside of the sliding plate 2102. The telescopic slide rod 2201 is slidably connected to the inside of the outside of the fixed box 2101. A pull rod 2202 is fixedly connected to the outside of the telescopic slide rod 2201.
[0034] Furthermore, under the action of the compression spring 2103, the sliding plate 2102 drives the locking rod 2104 to move inward on its own, so that the locking rod 2104 can automatically engage with the sleeve plate 2105 without external force intervention to complete the positioning of the screen plate 1303, which increases the stability of the screen plate 1303 after installation. At the same time, the operator only needs to pull the pull rod 2202 outward to drive the locking rod 2104 outward to release the positioning of the sleeve plate 2105, which makes it easy for the operator to fix and disassemble the screen plate 1303. The operation is simple and convenient for the operator to use.
[0035] In actual operation, when this device is in use and the screen plate 1303 needs to be disassembled, the operator first holds the handle 1103 and flips it upward. The upward flip of the handle 1103 causes the top cover 1101 to flip upward, completing the opening and closing of the top cover 1101. Then, the operator pulls the pull rods 2202 on both sides to move outward. The pull rods 2202 move outward through the telescopic slide rod 2201 and the slide plate 2102. The outward movement of the slide plate 2102 causes the locking rod 2104 to move outward. The locking rod 2104 moves outward and retracts into the fixed box 2101, disconnecting from the sleeve plate 2105. After that, the operator can lift the handle 1305 upward to drive the screen plate 1303 upward to complete the disassembly of the screen plate 1303. After that, the operator can replace or clean the screen plate 1303.
