In the description of the present utility model, the meaning of "a plurality" is two or more, unless otherwise specifically defined.

[0056] Refer to Figures 1 to 5A further description is made of an embodiment of a feed pellet grading sieve of the present utility model.

[0057] A feed pellet grading sieve includes a housing 1 and a cover plate 2. The cover plate 2 is disposed on the housing 1. It further includes a feed inlet 3, which is disposed on the cover plate 2 and fixedly connected to the cover plate 2, and is open at both the top and bottom. This is arranged to facilitate the entry of feed pellets onto the rolling screening component. At the same time, the rolling screening component is disposed inside the housing 1 for screening feed pellets, and a clamping component is used to secure the position of the screen 7. The clamping component is disposed on the rotor 14. A vibration component is disposed on the housing 1, and an anti-vibration component is also disposed on the housing 1. This is arranged to balance the shaking generated during the operation of the vibration component. A bracket 26 is disposed on the anti-vibration component to support the vibrator 9. A fixing component is disposed inside the housing 1, and a conveying component is disposed inside the housing 1. The screened feed pellets are conveyed to the discharge port 25 through the conveying component. The discharge port 25 is disposed on the housing 1 and cooperates with the conveyor belt 22 as the conveying outlet for the screened feed pellets. An external platform 24 is disposed on the housing 1 and there are two of them, providing a support point for the conveying motor 20.

[0058] Refer to Figure 1 and Figure 5 As a preferred embodiment, the rolling screening component includes a screening motor 4, which is disposed on the external platform 24 and fixedly connected to the external platform 24. This is arranged to provide power output for the rolling screening component. A screening chain is disposed on the screening motor 4, which can cooperate with the rotation of the motor to provide a movement path. The screening chain includes screening bars 5, which are disposed on the screening motor 4.

[0059] Screening bones 6 are disposed on the screening bars 5, one end of which is telescopic and is usually in a compressed state. This is arranged to facilitate the automatic elongation of the compressed end when it enters the clamping component and be clamped to secure the position of the screen 7. The screen 7 is disposed on the screening chain.

[0060] Before starting the screening, it is necessary to select the corresponding screen 7 according to the size of the pellets to be screened this time. Turn on the screening motor 4 to make the screening motor 4 start running, thereby driving the screening chain to rotate. Since the screening bones 6 are usually in a compressed state, when the screening bones 6 move between the first pressing member 17 and the second pressing member 19, they will be clamped by the first pressing member 17 and the second pressing member 19. When the screen 7 at this time is needed, the screening motor 4 can be turned off.

[0061] Refer to Figure 1, As a preferred embodiment, the vibration assembly includes a vibration connecting rod 8, which is arranged on the outer shell 1 and fixedly connected to the outer shell 1. When the vibrator 9 starts vibrating, it can shake the outer shell 1 through the vibration connecting rod 8, and this setting is used to achieve the effect of shaking the rolling screen assembly; the vibrator 9 is arranged on the vibration connecting rod 8 and fixedly connected to the vibration connection, and this setting provides the power output of the vibrating screen assembly.

[0062] After the preparation work is completed, first turn on the vibrator 9. The vibrator 9 will drive the vibration connecting rod 8 to start shaking. Since the vibration connecting rod 8 and the outer shell 1 are fixedly connected, the outer shell 1 will drive the screen mesh 7 to start shaking, and this setting can make the particle filtration faster and more efficient.

[0063] Refer to Figure 1 , As a preferred embodiment, the anti-vibration assembly includes an anti-vibration spring 10, which is arranged on the outer shell 1 and fixedly connected to the outer shell 1 to weaken the shaking of the vibration assembly on the support 26; the anti-vibration support 11 is arranged on the anti-vibration spring 10 and fixedly connected to the anti-vibration spring 10, and this setting provides a ground support point for the whole device.

[0064] In order to reduce the damage to the support 26 caused by the shaking generated by the vibrator 9, the anti-vibration spring 10 will store elastic potential energy when the device shakes, thereby reducing the damage to the support 26 caused by the shaking.

[0065] Refer to Figure 4 , As a preferred embodiment, the fixing assembly includes a handle 12, which is arranged on the outer shell 1 and slidably connected to the outer shell 1. Rotating the handle 12 can fix the position of the screen mesh 7; a fixing screw 13 is arranged on the handle 12 and fixedly connected to the handle 12 to fix the handle 12 and the rotor 14; the rotor 14 is arranged on the fixing screw 13 and fixedly connected to the fixing screw 13. Due to its special shape with different widths and heights, this setting enables the handle 12 to change the gap between the first pressing member 17 and the second pressing member 19 by changing the direction of the rotor 14 when the handle 12 rotates;

[0066] Refer to Figure 4 , As a preferred embodiment, the clamping assembly includes a baffle 15, which is arranged on the rotor 14 and slidably connected to the rotor 14. When the rotor 14 is driven to rotate by the handle 12, the baffle 15 will apply different magnitudes of pressure to the pressure spring 18 according to the width of the rotor 14;

[0067] The compression rod 16 is arranged on the baffle 15 and fixedly connected to the baffle 15, thus providing a support point for the first extrusion member 17 and the second extrusion member 19 when they slide down; the first extrusion member 17 is arranged on the compression rod 16 and fixedly connected to the compression rod 16; the pressure spring 18 is arranged on the first extrusion member 17 and fixedly connected to the first extrusion member 17; the second extrusion member 19 is arranged on the pressure spring 18 and fixedly connected to the pressure spring 18.

[0068] With such an arrangement, when the screening bone 6 moves between the first extrusion member 17 and the second extrusion member 19, it will be clamped by the first extrusion member 17 and the second extrusion member 19. When the screening mesh 7 is needed at this time, the screening motor 4 can be turned off. If the screening mesh 7 at this time is not the required one, then pull the handle to drive the rotor 14 to start rotating. Because the length and width of the rotor 14 are different, when rotating, the shorter ends of the rotor 14 will rotate and contact the baffle 15, thereby releasing the elastic potential energy of the compressed pressure spring 18. At this time, the gap between the first extrusion member 17 and the second extrusion member 19 becomes larger, allowing the screening bone 6 to leave until it rotates to the required screening mesh 7 and the screening motor 4 is turned off.

[0069] Refer to Figure 3 As a preferred embodiment, the conveying assembly includes a conveying motor 20 arranged on the external platform 24 and fixedly connected to the external platform 24, thus providing power output for the conveying chain; the conveying chain is arranged on the conveying motor 20 and connected to the conveying motor 20, serving as an intermediate member for the power output of the conveying motor 20; the driving wheel 21 is arranged on the conveying chain and is the main component for driving the conveyor belt 22 to rotate; the conveyor belt 22 is arranged on the driving wheel 21 and is slidably connected to the driving wheel 21, thus being arranged to convey the screened feed particles to the discharge port 25; the framework 23 is arranged on the conveyor belt 22, thus ensuring that the conveying device will not collapse in the middle when conveying a large amount of feed particles.

[0070] The filtered particles will fall onto the conveyor belt 22 directly below. At this time, turn on the conveying click switch to convey the filtered particles to the discharge port 25. Then, the unfiltered particles are still on the screening mesh 7. At this time, turn on the screening motor 4 and pull the handle at the same time to make the screening chain start to rotate, so that the screening mesh 7 tilts, and the unfiltered particles will fall onto the conveyor belt 22 below and will be conveyed to different discharge ports 25 accordingly.

[0071] The foregoing description of the embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to the embodiments shown herein, but rather to the broadest scope consistent with the principles and novel features disclosed herein.
