Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a feed powdering rate measuring instrument for feed processing. Background Technology

[0002] Powdering rate is the percentage of pelleted feed that turns into powder during conveying, transportation, or other external forces. The testing method involves placing a unit weight of pelleted or broken feed in a rotary container, starting the equipment, and typically removing the sample after 10 minutes and sieving it. The percentage of the material passing through the sieve (powder) is then calculated. Feed powdering rate is an important indicator of pelleted feed quality. It represents the proportion of pellets that may break into powder during use, such as when subjected to compression, abrasion, or impact during transportation. The powdering rate needs to be measured during feed processing.

[0003] For example, the feed powdering rate tester for feed processing disclosed in the utility model with authorization announcement number CN221100235U uses a motor to drive a turntable to rotate. The turntable, in conjunction with the elastic action of a spring, drives a fixed frame to move back and forth, thereby sieving the feed powder. By setting a collection box, which is slidably set on the weighing platform, it is convenient to collect the powdered feed after sieving and then remove it from the weighing platform.

[0004] The existing technology still has the following problems when used:

[0005] The device avoids the pelleted feed from colliding and being crushed due to vertical vibration by using a horizontal sieving method that moves left and right. It also prevents the feed from colliding and being crushed with the fixed frame during the sieving process by setting up protective blocks. However, when the pelleted feed moves on the screen surface and comes into contact with the protective blocks, the pelleted feed moves in the opposite direction under the elastic force of the protective blocks, thus moving towards and colliding with other pelleted feed, thereby reducing the accuracy of the detection.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a feed powdering rate tester for feed processing, comprising a base plate and a collection box, wherein the collection box is provided above the base plate;

[0008] An arc-shaped screen is installed on top of the collection box. The arc-shaped screen rotates slowly up and down to prevent the pellet feed from colliding with each other during screening.

[0024] Example

[0025] Please refer to Figures 1-4As shown, this utility model provides a feed powdering rate tester for feed processing, including a base plate 1 and a collection box 4. The collection box 4 is arranged above the base plate 1, and an arc-shaped screen 3 is arranged on the top of the collection box 4. A feed plate 2 is fixedly arranged on the top surface of the arc-shaped screen 3. A feed inlet is arranged through the center of the feed plate 2. The pellet feed to be tested is poured into the surface of the arc-shaped screen 3 through the feed inlet. The arc-shaped screen 3 rotates slowly up and down, so that the pellet feed can be turned before it moves on the surface of the arc-shaped screen 3 and touches the edge of the arc-shaped screen 3, thereby avoiding collision of the pellet feed due to moving towards each other and improving the accuracy of powdering rate detection. The collection box 4 can collect the powder screened out by the arc-shaped screen 3.

[0026] like Figures 1-3 As shown, the arc-shaped screen 3 is externally equipped with a rotating assembly, which consists of a first fixed plate 5, a first vertical plate 6, a second vertical plate 7, a limiting plate 8, a servo motor 9, a turntable 10, a rotating rod 11, a lifting plate 12, a vertical groove 13, a through groove 14, a U-shaped plate 15, a second fixed plate 16, and a T-shaped slider 17. The second fixed plate 16 and the first fixed plate 5 are fixedly installed on the left and right sides of the feed plate 2, respectively. The first vertical plate 6 is hinged to the other side of the first fixed plate 5. The bottom surface of the first vertical plate 6 is fixedly connected to the base plate 1. The top surface of the base plate 1 is fixedly equipped with the second vertical plate 7 and symmetrical limiting plates 8. The servo motor 9 is fixedly installed on the side of the second vertical plate 7. The output end of the servo motor 9 passes through the second vertical plate 7 and is rotatably connected to it. The end of the output end of the servo motor 9 is fixedly equipped with a turntable 10. The side of the turntable 10 away from the servo motor 9 is fixedly equipped with... A rotating rod 11 is provided, and a vertical groove 13 is provided on the inner side of the limiting plate 8. A lifting plate 12 adapted to the vertical groove 13 is slidably connected to the inner wall of the vertical groove 13. The lifting plate 12 is slidably connected to the limiting plate 8 through the vertical groove 13. A through groove 14 adapted to the rotating rod 11 is provided through the side of the lifting plate 12. When the turntable 10 rotates, it drives the rotating rod 11 to rotate. At the same time, the rotating rod 11 can move along the inner wall of the through groove 14 relative to the lifting plate 12. A U-shaped plate 15 is fixedly provided on the bottom surface of the lifting plate 12. A T-shaped slider 17 is hinged to the top surface of the end of the U-shaped plate 15 away from the lifting plate 12. A T-shaped groove adapted to the T-shaped slider 17 is provided on the bottom surface of the second fixed plate 16. The T-shaped slider 17 is slidably connected to the second fixed plate 16 through the T-shaped groove. Controlling the servo motor 9 to drive the turntable 10 to rotate can drive the U-shaped plate 15 to move up and down periodically, thereby driving the arc-shaped screen 3 to rotate up and down periodically.

[0027] Specifically, the servo motor 9 drives the turntable 10 to rotate, the turntable 10 rotates the rotating rod 11, and the rotating rod 11 moves relative to the lifting plate 12 along the inner wall of the through groove 14, thereby causing the lifting plate 12 to move up and down periodically. The movement of the lifting plate 12 causes the U-shaped plate 15 to move up and down periodically. The movement of the U-shaped plate 15 causes the T-shaped slider 17 to move relative to the second fixed plate 16 along the inner wall of the T-shaped slide groove, thereby causing the second fixed plate 16 to rotate up and down periodically. The rotation of the second fixed plate 16 causes the arc-shaped screen 3 to rotate up and down periodically.

[0028] like Figures 1-4 As shown, a connecting assembly is provided between the arc-shaped screen 3 and the collection box 4. The connecting assembly consists of a top plate 18, connecting ropes 19, nuts 20, insert rods 21, threaded rods 22, and through holes 23. Four connecting ropes 19 are fixedly installed on the side of the feed plate 2, and the top plate 18 is fixedly installed at the other end of the connecting ropes 19. Nuts 20 are fixedly installed on the other side of the top plate 18. Insert rods 21 are fixedly installed at the four corners of the top surface of the collection box 4. Threaded rods 22 that fit the nuts 20 are fixedly installed on the top surface of the insert rods 21. The nuts 20 and threaded rods 22 are threadedly connected. The cross-sectional area of ​​the threaded rods 22 is smaller than the cross-sectional area of ​​the insert rods 21. The height of the insert rods 21 is the same as the thickness of the feed plate 2. Through holes are provided at the four corners of the top surface of the feed plate 2. The insertion rod 21 is adapted to the through hole 23 on the bottom surface. The insertion rod 21 is slidably connected to the feed plate 2 through the through hole 23. The collection box 4 is placed below the arc screen 3 and the insertion rod 21 is aligned with the through hole 23. The collection box 4 is moved upward so that the insertion rod 21 is engaged inside the through hole 23. At this time, the threaded rod 22 is located on the top surface of the feed plate 2. The nut 20 is rotated in sequence to make the nut 20 threadedly connected to the threaded rod 22. The relative position of the arc screen 3 and the collection box 4 can be fixed, thereby preventing the powder inside the collection box 4 from moving due to the up and down rotation of the feed plate 2 and the arc screen 3, which would cause the powder to float out of the collection box 4. The connecting component makes it easy to disassemble the collection box 4 after the powder screening is completed.

[0029] Specific working principle:

[0030] When using this device, the pelleted feed to be tested is poured into the surface of the arc-shaped screen 3 through the feed inlet. The collection box 4 is placed below the arc-shaped screen 3, and the insertion rod 21 is aligned with the through hole 23. The collection box 4 is moved upward so that the insertion rod 21 is engaged inside the through hole 23. At this time, the threaded rod 22 is located on the top surface of the feed plate 2. The nut 20 is rotated in sequence to make the nut 20 threadedly connected to the threaded rod 22, which can fix the relative position of the arc-shaped screen 3 and the collection box 4. The servo motor 9 is controlled to drive the turntable 10 to rotate slowly. The rotation of the turntable 10 drives the rotating rod 11 to rotate. When the rotating rod 11 rotates, it moves relative to the lifting plate 12 along the inner wall of the through groove 14, thereby driving the lifting plate 12 to move up and down periodically. The movement of the lifting plate 12 drives the U-shaped plate 15 to move up and down periodically. The movement of plate 15 causes T-shaped slider 17 to move relative to the second fixed plate 16 along the inner wall of the T-shaped groove, thereby driving the second fixed plate 16 to rotate periodically up and down. The rotation of the second fixed plate 16 drives the arc screen 3 to rotate periodically up and down slowly. The slow up and down rotation of the arc screen 3 allows the pellet feed to be turned before it moves on the surface of the arc screen 3 and contacts the edge of the arc screen 3, thereby avoiding collisions caused by the pellet feed moving towards each other and improving the accuracy of the pulverization rate detection. The collection box 4 can collect the powder screened out by the arc screen 3. After the sieving is completed, the nut 20 is rotated in reverse to disengage the nut 20 from the threaded rod 22. The collection box 4 can be moved downwards and removed for weighing by an external measuring instrument, thereby facilitating the calculation of the feed pulverization rate.
