[0002] With the development of aquaculture, fish feed, which is simple to produce, inexpensive to prepare, and has good feeding effects, is becoming increasingly popular. However, fish feed is a special type of feed, requiring fine particle size. After the feed is ground, it is necessary to have dedicated personnel regularly check whether the fineness of the material meets the standards. Currently, feed particle size is usually determined by sieving. Typically, a unit weight of pelleted feed is placed in a testing device, the sample is sieved, and the percentage of powder in the sample weight is calculated. However, feed fineness testing is cumbersome, as it is inconvenient to install and disassemble the filter screen. This makes it difficult to collect and weigh the feed from different layers of the test sieve after sieving, resulting in low testing efficiency. Furthermore, it is inconvenient to assemble test sieves of different standards, limiting its applicability. Therefore, we need to propose a device for determining the fineness of feed grinding in fish feed production. Utility Model Content

[0019] Please see Figure 1-4 This utility model provides: a device for determining the fineness of powdered fish feed, including a vibrating screen body 1, a support seat 2 installed on the top of the vibrating screen body 1, and a collection box 10 assembled on the top of the support seat 2; the surface of the support seat 2 is provided with adjustment grooves 5, and the interior of the adjustment grooves 5 is provided with positioning components for assembling the collection box 10. The top of the collection box 10 is sequentially equipped with a second screen box 13 and a first screen box 14 for screening fish feed through positioning slots 12. The top of the first screen box 14 is equipped with a sealing cover 15 for sealing; the two sides of the support seat 2 are connected to an assembly frame 3, and the surface of the assembly frame 3 is slidably connected to a connecting guide rod 17. The surface of the connecting guide rod 17 is provided with a locking component for sealing and fixing the second screen box 13 and the first screen box 14.

[0020] It is worth noting that the coordinated design of the bearing seat 2, assembly frame 3, collection box 10, connecting guide rod 17, positioning component, and locking component improves the simplicity and speed of the clamping and disassembly process. The collection box can be fixed or loosened by simply rotating the adjusting screw, and the upper sieve box assembly can be tightened or released by rotating the adjusting lever. This simplifies the operation process of changing sieves and taking and placing samples, greatly reduces the labor intensity of operators, shortens the time required for a single test, and helps to improve the efficiency of the production quality inspection process.

[0021] Specifically, the positioning component includes: an adjusting screw 6 rotatably mounted on the inner wall of the adjusting groove 5, and a locking block 7 movably connected to the surface of the adjusting screw 6; wherein, limit blocks 8 are connected to both sides of the locking block 7, and the surface of the limit blocks 8 is slidably connected to the inner wall of the adjusting groove 5.

[0022] In addition, the adjusting groove 5 is a structure for assembling the locking block 7, and the adjusting screw 6 is a structure for adjusting and controlling the locking block 7, so that the locking block 7 can fix inspection sieve boxes of different specifications. The limiting block 8 is used in conjunction with the adjusting groove 5 to improve the stability of the locking block 7. The top of the bearing seat 2 is provided with a central hole that cooperates with the collection box 10.

[0023] An anti-detachment spring 9 is fitted onto the surface of the adjusting screw 6, and one end of the anti-detachment spring 9 is connected to the outer surface of the locking block 7. A limit ring 11 is connected to the bottom of the surface of the collection box 10, and the locking block 7 is engaged with the surface of the limit ring 11 by means of the adjusting screw 6.

[0024] Furthermore, the anti-detachment spring 9 acts on the locking block 7 to ensure that after the adjusting screw 6 locks the locking block 7, the locking block 7 remains in a locked and positioned state, improving the stability of the installation. The connecting plate 18 is a snap-fit ​​anti-detachment structure that cooperates between the collection box 10 and the locking block 7.

[0025] The locking assembly includes: a connecting plate 18 connected to the top of the connecting guide rod 17, and an adjusting pressure rod 21 threadedly installed in the center of the connecting plate 18; wherein, the bottom end of the adjusting pressure rod 21 is rotatably connected to a positioning pressure plate 19, and auxiliary support plates 20 are provided on both sides of the positioning pressure plate 19, and the auxiliary support plates 20 are slidably connected to the surface of the connecting guide rod 17.

[0026] The connecting plate 18 is assembled with the adjusting pressure rod 21, thereby controlling the positioning pressure plate 19 through the adjusting pressure rod 21. The positioning pressure plate 19 presses the sealing cover 15, so that the sealing cover 15 is sealed to the top of the first screen box 14. The top of the sealing cover 15 is provided with a central hole that matches the positioning pressure plate 19, so as to quickly position and press and seal. The connecting guide rod 17 works with the auxiliary support plate 20 to guide the lifting and lowering of the positioning pressure plate 19, ensuring the stability of the structure.

A sliding block 16 is connected to the bottom end of the connecting guide rod 17, and a positioning guide rod 4 is provided on the inner wall of the assembly frame 3. The sliding block 16 is slidably mounted on the surface of the positioning guide rod 4.

[0028] In addition, the anti-loosening spring 22 restricts the movement of the positioning pressure plate 19, reducing the possibility of loosening due to vibration. The sliding block 16 is a structure that connects the guide rod 17 to the assembly frame 3. Together with the positioning guide rod 4, it can effectively ensure the accuracy of the movement position, allowing for quick and convenient removal and inspection of the second sieve box 13 and the first sieve box 14. The sliding fit between the limit block and the adjusting groove, and the fit between the sliding block and the positioning guide rod, ensure that all moving parts move smoothly in the linear direction without shaking or deflection.

[0029] The adjusting groove 5 on the surface of the support base 2 and the positioning assembly consisting of the adjusting screw 6 and locking block 7 allow for flexible adjustment and secure locking of the limiting ring 11 at the bottom of the collection box 10 of different sizes. This enables the device to adapt to various specifications of standard test sieve boxes, further improving the versatility and applicability of the testing equipment. The locking assembly, through the connecting guide rod 17, connecting plate 18, and adjusting pressure rod 21, applies a stable and uniform downward pressure to the stacked first sieve box 14 and second sieve box 13 from the top. The positioning pressure plate, in conjunction with the anti-loosening spring 22, ensures a long-lasting and stable locking force, effectively preventing misalignment, gaps, or material splashing caused by loose sieve boxes during high-frequency vibration of the vibrating sieve machine, thereby ensuring the accuracy and repeatability of the screening results and reducing measurement errors.
