Description

Technical Field

[0001] The present invention belongs to the technical field of material screening, and in particular relates to a screening device and a method for processing cattle and sheep feed. Background Art

[0002] Cattle and sheep feed refers to nutrients specifically provided to ruminants such as cattle and sheep, designed to meet their nutritional needs for growth, maintenance, and production (such as milk and meat production). The selection and use of feed significantly impacts the health, growth performance, and profitability of cattle and sheep. Screening is essential for selecting feed, requiring the use of screening equipment.

[0003] Chinese patent CN119216226A discloses a livestock feed screening device, including a rotary vibrating screen body, a discharge port and a screen; also including a feed hopper; a collecting box; a detection mechanism; an adjustment mechanism; and a combing mechanism. The combing mechanism is located inside the rotary vibrating screen body. This livestock feed screening device detects the discharge volume of multiple discharge ports per unit time through the detection mechanism. When the detection mechanism detects that the discharge volume of the discharge port per unit time is reduced, the adjustment mechanism adjusts the falling speed of the feed in the feed hopper to avoid the rotary vibrating screen body from having more feed fed in and less discharged, resulting in a large amount of feed accumulating on the screen, affecting the screening efficiency. The combing mechanism combs the multiple screens respectively to avoid feed particles clogging the screen mesh, affecting the screening efficiency, reducing the workload of the staff. The staff do not need to stay near the rotary vibrating screen body for a long time, avoiding the dust generated by the vibration affecting the health of the staff. Although the current screening device can also realize the screening process of feed, when using rotary screening, although it has a good screening effect, the screened feed will be thrown to the periphery and accumulate, which is not easy to discharge. Moreover, using rotary screening alone cannot improve the screening accuracy of feed. The actual application effect of the equipment is not good, and certain improvements are needed. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem that although the current screening device can also realize the screening process of feed, when using rotary screening, although it has a good screening effect, the screened feed will be thrown to the periphery and accumulate, making it difficult to discharge the feed. Moreover, the use of rotary screening alone cannot improve the screening accuracy of the feed, and the actual application effect of the equipment is poor. A screening device and method for cattle and sheep feed processing are proposed.

[0005] In order to achieve the above-mentioned object, the present invention adopts the following technical solution: a screening device for cattle and sheep feed processing, comprising a casing, a screening tank fixedly mounted on the top of the casing, a top cover provided on the top surface of the casing, a feed pipe provided at the center of the top cover, a plurality of material-diverting plates provided on the bottom surface of the top cover, a discharge port provided on both side outer walls of the casing, a material control valve provided inside the discharge port, a material guide platform fixedly mounted on the inner wall of the bottom surface of the casing, a built-in motor fixedly mounted inside the material guide platform, and an electric heating pipe provided in the shell cavity of the material guide platform;

[0013] The vibration block is movably installed on the inner side of the inner stroke groove, and an oscillation spring is fixedly installed on the top of the vibration block. One end of the oscillation spring is fixedly connected to the inner wall of the top surface of the inner stroke groove, and the bottom surface of the bottom scraper is in close contact with the upper surface of the vibration screen plate.

[0014] As a further description of the above technical solution:

[0015] The beating assembly includes a mounting shaft frame, which is fixedly mounted on the inner wall of the screening tank, a mounting shaft is rotatably mounted inside the mounting shaft frame, a beating blade is fixedly mounted outside the mounting shaft, a driven wheel is fixedly mounted on the top end of the mounting shaft, and the driven wheel is rollingly connected to the centrifugal screening cover.

[0016] As a further description of the above technical solution:

[0017] The mobile dispersion assembly includes a mobile shell, which is threadedly installed on the outside of the reciprocating screw through a threaded hole set inside the mobile shell. The two side walls of the mobile shell are slidably connected to the inner side wall of the casing. The bottom of the mobile shell is provided with a bottom groove, and two vertical frames are movably installed in the bottom groove through a built-in spring, and a horizontal frame is fixedly installed between the two vertical frames.

[0018] As a further description of the above technical solution:

[0019] Two elastic potential energy storage racks are fixedly installed on the top surface of the horizontal frame, and a wheel groove is provided on the top of the elastic potential energy storage rack. A guide wheel is rotatably installed in the wheel groove through a rotating shaft, and a top slot is provided on the top surface of the movable shell.

[0020] As a further description of the above technical solution:

[0021] The guide wheel is located on the inner side of the top slot, a wheel axle is rotatably installed between the two longitudinal frames, a dispersion plate is fixedly installed on the outside of the wheel axle, and walking wheels are fixedly installed at both ends of the wheel axle, and the walking wheels are rollingly connected to the material guide ladder.

[0022] As a further description of the above technical solution:

[0023] A driven bevel gear is fixedly mounted on one end of the reciprocating screw, and a driving bevel gear is fixedly mounted on the outside of the driving rod. The driving bevel gear and the driven bevel gear are meshed with each other.

[0024] The present invention also discloses a method for using a screening device for cattle and sheep feed processing, comprising the following steps:

[0025] S1. When screening feed, feed is added to the screening tank through the feed pipe. At this time, the built-in motor is turned on to drive the centrifugal screening component to rotate. Since a material-diverting plate is provided at the bottom of the top cover, the material-diverting plate can automatically divert the feed. Due to the centrifugal force of the rotation, the screened feed will be discharged through the two sides and bottom of the centrifugal screening component.

[0026] S2. During the above process, the driven wheel can rotate along with the centrifugal screening cover. Since the diameter of the driven wheel is much smaller than that of the centrifugal screening cover, the driven wheel also rotates rapidly. The beating blades can beat the thrown feed to make it evenly distributed. The feed that has been screened once will fall on the vibrating screen plate. When the centrifugal screening assembly rotates, it can also drive the telescopic plate and the bottom scraper at the bottom to rotate synchronously, so as to scrape the feed remaining on the vibrating screen plate, so that the material passes through the vibrating screen plate for secondary screening.

[0027] S3. When centrifugal screening is performed, the driving bevel gear can rotate, and the driving bevel gear can drive the reciprocating screw with the driven bevel gear to rotate. When the reciprocating screw rotates, it can drive the mobile dispersion component thereon to move back and forth;

[0028] S4. When the mobile dispersing assembly moves, the telescopic vertical frame allows the running wheels at its bottom to continuously roll on the inclined surface of the feed guide platform. As the running wheels roll, the dispersing plate is driven to rotate, dispersing the feed that has passed the secondary screening and landed on the surface of the feed guide platform. Simultaneously, the electric heating tubes inside the feed guide platform are activated to raise the temperature on the platform, simultaneously dehumidifying and drying the feed, ensuring particle dispersion and improving the taste. After processing is complete, simply open the feed control valve at the discharge port, and the feed will automatically slide out.

[0029] S5. When the traveling wheel moves upward along the inclined surface of the material guide platform, the longitudinal frame will expand and contract inward, thereby driving the transverse frame and the elastic potential energy storage rack thereon to move upward. At this time, the guide wheel moves upward, contacts the inner wall of the top surface of the casing, and rolls on it;

[0030] S6. As the horizontal frame continues to rise, the elastic potential energy storage frame is compressed. When the guide wheel moves to the bottom of the vibrating screening mechanism, the elastic potential energy stored in the elastic potential energy storage frame is released instantly. At this time, the guide wheel is quickly bounced up, and the guide wheel can generate impact force on the vibrating screen plate, causing it to move upward. At this time, the guide wheel also reaches the highest point. The vibrating screen plate that is pushed up can vibrate continuously under the action of the vibration spring, and the feed remaining in the sieve holes of the vibrating screen plate can be stably shaken off.

[0031] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0032] 1. In the present invention, a centrifugal screening component, a beating component and a vibration screening mechanism are matched and provided. When screening the feed, the feed is added to the interior of the screening tank through the feed pipe. At this time, the built-in motor is turned on to drive the centrifugal screening component to rotate. Since a paddle plate is provided at the bottom of the top cover, the paddle plate can automatically paddle the feed, and due to the centrifugal force of the rotation, the screened feed will be discharged through the two sides and the bottom of the centrifugal screening component. In the above process, the driven wheel can rotate with the centrifugal screening cover. Since the diameter of the driven wheel is much smaller than that of the centrifugal screening cover, the driven wheel also rotates rapidly, and the beating blades can beat the thrown feed, so that The centrifugal screening component can be evenly distributed, and the feed screened once will fall on the vibrating screen plate. When the centrifugal screening component rotates, it can also drive the telescopic plate and the bottom scraper at the bottom to rotate synchronously, so as to scrape the feed remaining on the vibrating screen plate, so that the material can be screened twice through the vibrating screen plate. Through this design, the centrifugal screening is combined with the vibrating screening to realize the secondary screening of the feed. At the same time, the feed thrown out by the centrifuge can be beaten at high speed during screening, which can effectively make the feed evenly distributed and avoid accumulation. At the same time as the centrifugal screening, the feed on the vibrating screen plate can be scraped in real time to ensure the double screening effect and improve the application effect of the equipment.

[0033] 2. In the present invention, a mobile dispersing assembly is provided. When centrifugal screening is performed, the driving bevel gear can rotate, and the driving bevel gear can drive the reciprocating screw with the driven bevel gear to rotate. When the reciprocating screw rotates, it can drive the mobile dispersing assembly on it to move back and forth. When the mobile dispersing assembly is displaced, since the vertical frame is designed to be telescopic, the walking wheels at the bottom can continuously roll on the inclined surface of the guide ladder. When the walking wheels roll, the dispersing plate can be driven to rotate, which can disperse the feed that has passed the secondary screening and landed on the surface of the guide ladder. At the same time, the electric heating pipe in the guide ladder is turned on to increase the temperature on the guide ladder, which can simultaneously achieve dehumidification and drying of the feed, ensure the particle dispersion of the feed, and improve the taste. After the processing is completed, only the control valve of the discharge port needs to be opened, and the feed can automatically slide and be discharged. Through this design, the material can be quickly dried and dissipated after the secondary screening of the feed, thereby improving the particle dispersion of the feed, avoiding the situation that the feed is wet and agglomerated, and extending the shelf life of the feed. Moreover, the material can be automatically discharged when needed, further improving the application effect of the equipment.

[0034] When the guide wheel is moved upward along the inclined surface of the guide platform, the vertical frame will expand and contract inwardly, thereby driving the horizontal frame and the elastic potential energy storage frame on it to move upward, and the guide wheel moves upward, contacts the inner wall of the top surface of the casing, and rolls on it. As the horizontal frame continues to rise, the elastic potential energy storage frame is compressed, and when the guide wheel moves to the bottom of the vibration screening mechanism, the elastic potential energy stored in the elastic potential energy storage frame is instantly released. At this time, the guide wheel is quickly rebounded, and the guide wheel can generate an impact force on the vibration screen plate, causing it to move upward. At this time, the guide wheel also reaches the highest point, and the vibrating screen plate pushed up can vibrate continuously under the action of the vibration spring. In this way, the mobile dispersing assembly can realize regular and continuous vibration of the vibrating screen plate, and the residual feed in the sieve holes of the vibrating screen plate can be stably shaken off, thereby continuously ensuring the application effect of the vibrating screen plate, and the vibration effect has the characteristics of multiple durations and high frequency compared with the traditional single vibration, thereby improving the processing effect of the vibrating screen plate.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0047] See also Figures 1-9 The present invention provides a technical solution: a screening device for cattle and sheep feed processing, comprising a casing 3, a screening tank 4 fixedly mounted on the top of the casing 3, a top cover 2 provided on the top surface of the casing 3, a feed pipe 1 provided at the center of the top cover 2, a plurality of material shifting plates 7 provided on the bottom surface of the top cover 2, a discharge port 5 provided on both sides of the outer wall of the casing 3, a material control valve provided inside the discharge port 5, a material guide platform 12 fixedly mounted on the inner wall of the bottom surface of the casing 3, a built-in motor 11 fixedly mounted inside the material guide platform 12, and an electric heating pipe provided in the shell cavity of the material guide platform 12;

[0048] A driving rod 14 is fixedly installed at one end of the output shaft of the built-in motor 11, and a centrifugal screening component 6 is provided at the top of the driving rod 14. The centrifugal screening component 6 is used for the first-level screening of the feed. A vibration screening mechanism 9 is movably installed on the inner surface of the screening tank 4. The vibration screening mechanism 9 is used for the secondary screening of the feed. A reciprocating screw 17 is rotatably installed on the inner wall of one side of the casing 3, and a mobile dispersing component 10 is movably installed on the outside of the reciprocating screw 17. The mobile dispersing component 10 is used for dispersing the screened material and driving the vibration screening mechanism 9 to vibrate. A plurality of beating components 8 are provided on the inner side of the screening tank 4. The beating components 8 are used for stable dispersion of the feed thrown out by centrifugal screening.

[0049] The centrifugal screening assembly 6 includes a centrifugal screening cover 61, on the bottom surface of which two mounting bottom shells 62 are fixedly mounted. The interiors of the two mounting bottom shells 62 are both movably mounted with telescopic plates 64 via telescopic springs 63, and a bottom scraper 65 is fixedly mounted at the bottom end of the telescopic plates 64.

[0050] The vibrating screening mechanism 9 includes a vibrating screen plate 92, which is movably mounted on the inner side of the screening tank 4. Two vibrating blocks 93 are fixedly mounted on the outer surface of the vibrating screen plate 92. An inner stroke groove 13 is provided on the inner surface of the screening tank 4. The vibrating block 93 is movably mounted on the inner side of the inner stroke groove 13. An oscillation spring 91 is fixedly mounted on the top of the vibrating block 93. One end of the oscillation spring 91 is fixedly connected to the inner wall of the top surface of the inner stroke groove 13. The bottom surface of the bottom scraper 65 is in close contact with the upper surface of the vibrating screen plate 92.

[0051] The beating assembly 8 includes a mounting shaft frame 81, which is fixedly mounted on the inner wall of the screening tank 4. A mounting shaft 84 is rotatably mounted inside the mounting shaft frame 81, a beating blade 83 is fixedly mounted outside the mounting shaft 84, and a driven wheel 82 is fixedly mounted on the top of the mounting shaft 84. The driven wheel 82 is rollingly connected to the centrifugal screening cover 61.

[0052] Furthermore: when screening the feed, the feed is added to the interior of the screening tank 4 through the feed pipe 1. At this time, the built-in motor 11 is turned on to drive the centrifugal screening assembly 6 to rotate. Since a material stripping plate 7 is provided at the bottom of the top cover 2, the material stripping plate 7 can automatically strip the feed, and due to the centrifugal force of rotation, the screened feed will be discharged through the two sides and the bottom of the centrifugal screening assembly 6. In the above process, the driven wheel 82 can rotate with the centrifugal screening cover 61. Since the diameter of the driven wheel 82 is much smaller than the diameter of the centrifugal screening cover 61, the driven wheel 82 also rotates rapidly. The beating blade 83 can beat the thrown feed to make it evenly distributed. The feed screened once will fall on the vibrating screen plate 92. When the centrifugal screening assembly 6 rotates, it can also drive the telescopic plate 64 and the bottom scraper 65 at its bottom to rotate synchronously, so as to scrape the feed remaining on the vibrating screen plate 92, so that the material passes through the vibrating screen plate 92 for secondary screening.

[0053] Through this design, centrifugal screening is combined with vibration screening to achieve secondary screening of feed. At the same time, the feed thrown out by the centrifuge can be beaten at high speed during screening, which can effectively distribute the feed evenly and avoid accumulation. At the same time as centrifugal screening, the feed on the vibration screen plate 92 can be scraped in real time to ensure the double screening effect and improve the application effect of the equipment.

[0054] See also Figure 7The mobile dispersion component 10 includes a mobile shell 102, which is threadedly installed on the outside of the reciprocating screw 17 through a threaded hole set inside the mobile shell 102. The two side walls of the mobile shell 102 are slidably connected to the inner wall of the casing 3. A bottom groove is set at the bottom of the mobile shell 102, and two vertical frames 106 are movably installed in the bottom groove through a built-in spring 104. A horizontal frame 105 is fixedly installed between the two vertical frames 106.

[0055] A driven bevel gear 16 is fixedly mounted on one end of the reciprocating screw 17 , and a driving bevel gear 15 is fixedly mounted on the outside of the driving rod 14 . The driving bevel gear 15 and the driven bevel gear 16 are meshed with each other.

[0056] Furthermore, when centrifugal screening is carried out, the driving bevel gear 15 can rotate, and the driving bevel gear 15 can drive the reciprocating screw 17 with the driven bevel gear 16 to rotate. When the reciprocating screw 17 rotates, it can drive the mobile dispersing component 10 thereon to move back and forth. When the mobile dispersing component 10 is displaced, since the vertical frame 106 is designed to be telescopic, the walking wheel 109 at its bottom can continue to roll on the inclined surface of the guide ladder 12. When the walking wheel 109 rolls, the dispersing plate 108 can be driven to rotate, which can disperse the feed that has passed the secondary screening and fallen on the surface of the guide ladder 12. At the same time, the electric heating pipe in the guide ladder 12 is turned on to increase the temperature on the guide ladder 12, which can simultaneously realize the dehumidification and drying of the feed, ensure the particle dispersion of the feed, and improve the taste. After the processing is completed, it is only necessary to open the control valve of the discharge port 5, and the feed can automatically slide down and be discharged.

[0057] Through this design, after the secondary screening of the feed, the material drying and heat dissipation functions can be quickly realized, the particle dispersion of the feed can be improved, the feed can be prevented from getting wet and clumping, the shelf life of the feed can be increased, and the material can be automatically discharged when needed, further improving the application effect of the equipment.

[0058] See also Figure 5 and Figure 7 Two elastic potential energy storage frames 107 are fixedly installed on the top surface of the horizontal frame 105. A wheel groove is provided on the top of the elastic potential energy storage frame 107. A guide wheel 103 is rotatably installed in the wheel groove through a rotating shaft. A top slot 101 is provided on the top surface of the movable shell 102. The guide wheel 103 is located on the inner side of the top slot 101. A wheel axle is rotatably installed between the two vertical frames 106. A dispersion plate 108 is fixedly installed on the outside of the wheel axle. Travel wheels 109 are fixedly installed at both ends of the wheel axle. The travel wheel 109 is rollingly connected to the material guide ladder 12.

[0059] Furthermore, when the walking wheel 109 moves upward along the inclined surface of the material guide platform 12, the vertical frame 106 will expand and contract inward, thereby driving the horizontal frame 105 and the elastic potential energy storage frame 107 thereon to move upward. At this time, the guide wheel 103 moves upward, contacts the inner wall of the top surface of the casing 3, and rolls on it. As the horizontal frame 105 continues to rise, the elastic potential energy storage frame 107 is compressed. When the guide wheel 103 moves to the bottom of the vibration screening mechanism 9, the elastic potential energy stored in the elastic potential energy storage frame 107 is instantly released. At this time, the guide wheel 103 is quickly ejected, and the guide wheel 103 can generate an impact force on the vibration screen plate 92, causing it to move upward. At this time, the guide wheel 103 also reaches the highest point, and the vibration screen plate 92 that is pushed up can continue to vibrate under the action of the vibration spring 91.

[0060] In this way, the mobile dispersion component 10 can achieve regular and continuous vibration of the vibrating screen plate 92, and the feed remaining in the sieve holes of the vibrating screen plate 92 can be stably shaken off, continuously ensuring the application effect of the vibrating screen plate 92. Compared with the traditional single vibration, the vibration effect has the characteristics of continuous multiple times and high frequency, thereby improving the processing effect of the vibrating screen plate 92.

[0061] The present invention also discloses a method for using a screening device for cattle and sheep feed processing, comprising the following steps:

[0062] S1. When screening feed, feed is added to the interior of the screening tank 4 through the feed pipe 1. At this time, the built-in motor 11 is turned on to drive the centrifugal screening assembly 6 to rotate. Since a material-diverting plate 7 is provided at the bottom of the top cover 2, the material-diverting plate 7 can automatically divert the feed. Due to the centrifugal force of the rotation, the screened feed will be discharged through the two sides and the bottom of the centrifugal screening assembly 6;

[0063] S2. During the above process, the driven wheel 82 can rotate along with the centrifugal screening cover 61. Since the diameter of the driven wheel 82 is much smaller than that of the centrifugal screening cover 61, the driven wheel 82 also rotates rapidly. The beating blades 83 can beat the thrown feed to make it evenly distributed. The once screened feed will fall on the vibrating screen plate 92. When the centrifugal screening assembly 6 rotates, it can also drive the telescopic plate 64 and the bottom scraper 65 at the bottom thereof to rotate synchronously, so as to scrape the feed remaining on the vibrating screen plate 92, so that the material passes through the vibrating screen plate 92 for secondary screening.

[0064] S3. When centrifugal screening is performed, the driving bevel gear 15 can rotate, and the driving bevel gear 15 can drive the reciprocating screw 17 with the driven bevel gear 16 to rotate. When the reciprocating screw 17 rotates, it can drive the mobile dispersion component 10 thereon to reciprocate;

[0065] S4. When the mobile dispersing assembly 10 is displaced, since the vertical frame 106 is designed to be telescopic, the running wheels 109 at its bottom can continuously roll on the inclined surface of the material guide platform 12. When the running wheels 109 roll, the dispersing plate 108 can be driven to rotate, and the feed that has passed the secondary screening and landed on the surface of the material guide platform 12 can be dispersed. At the same time, the electric heating tube in the material guide platform 12 is turned on to increase the temperature on the material guide platform 12, which can simultaneously achieve moisture removal and drying of the feed, ensure the particle dispersion of the feed, and improve the taste. After the processing is completed, only the control valve of the discharge port 5 needs to be opened, and the feed can automatically slide out;

[0066] S5. When the running wheel 109 moves upward along the inclined surface of the material guide platform 12, the vertical frame 106 will expand and contract inward, thereby driving the horizontal frame 105 and the elastic potential energy storage frame 107 thereon to move upward. At this time, the guide wheel 103 moves upward, contacts the inner wall of the top surface of the casing 3, and rolls on it;

[0067] S6. As the cross frame 105 continues to rise, the elastic potential energy storage frame 107 is compressed. When the guide wheel 103 moves to the bottom of the vibrating screening mechanism 9, the elastic potential energy stored in the elastic potential energy storage frame 107 is released instantly. At this time, the guide wheel 103 is quickly launched, and the guide wheel 103 can generate an impact force on the vibrating screen plate 92, causing it to move upward. At this time, the guide wheel 103 also reaches the highest point. The vibrating screen plate 92 that is pushed up can vibrate continuously under the action of the vibration spring 91, and the feed remaining in the sieve holes of the vibrating screen plate 92 can be stably shaken off.

[0068] Working principle: When screening the feed, the feed is added to the inside of the screening tank 4 through the feed pipe 1. At this time, the built-in motor 11 is turned on to drive the centrifugal screening assembly 6 to rotate. Since a material stripping plate 7 is provided at the bottom of the top cover 2, the material stripping plate 7 can automatically strip the feed, and due to the centrifugal force of rotation, the screened feed will be discharged through the two sides and the bottom of the centrifugal screening assembly 6; in the above process, the driven wheel 82 can rotate with the centrifugal screening cover 61. Since the diameter of the driven wheel 82 is much smaller than the diameter of the centrifugal screening cover 61, the driven wheel 82 also rotates rapidly, and the beating blade 83 can beat the thrown feed to make it evenly distributed. The feed screened once will fall on the vibrating screen plate 92. When the centrifugal screening assembly 6 rotates, it can also drive the telescopic plate 64 and the bottom scraper 65 at its bottom to rotate synchronously, so as to scrape the feed remaining on the vibrating screen plate 92, so that the material passes through the vibrating screen plate 92 for secondary screening;

[0069] When centrifugal screening is carried out, the driving bevel gear 15 can rotate, and the driving bevel gear 15 can drive the reciprocating screw 17 with the driven bevel gear 16 to rotate. When the reciprocating screw 17 rotates, it can drive the mobile dispersing assembly 10 thereon to move back and forth; when the mobile dispersing assembly 10 is displaced, since the vertical frame 106 is designed to be telescopic, the walking wheel 109 at its bottom can continuously roll on the inclined surface of the guide ladder 12. When the walking wheel 109 rolls, the dispersing plate 108 can be driven to rotate, which can disperse the feed that has passed the secondary screening and fallen on the surface of the guide ladder 12. At the same time, the electric heating pipe in the guide ladder 12 is turned on to increase the temperature on the guide ladder 12, which can simultaneously realize the dehumidification and drying of the feed, ensure the particle dispersion of the feed, and improve the taste. After the processing is completed, it is only necessary to open the control valve of the discharge port 5, and the feed can automatically slide out;

[0070] When the walking wheel 109 moves upward along the inclined surface of the material guide ladder 12, the vertical frame 106 will expand and contract inward, thereby driving the horizontal frame 105 and the elastic potential energy storage frame 107 thereon to move upward. At this time, the guide wheel 103 moves upward, contacts the inner wall of the top surface of the casing 3, and rolls on it; as the horizontal frame 105 continues to rise, the elastic potential energy storage frame 107 is compressed, and when the guide wheel 103 moves to the bottom of the vibrating screening mechanism 9, the elastic potential energy stored in the elastic potential energy storage frame 107 is instantly released, and the guide wheel 103 is quickly rebounded at this time. The guide wheel 103 can generate an impact force on the vibrating screen plate 92, causing it to move upward, and at this time the guide wheel 103 also reaches the highest point. The vibrating screen plate 92 that is pushed up can vibrate continuously under the action of the vibration spring 91, and the feed remaining in the sieve holes of the vibrating screen plate 92 can be stably shaken off.

When screening feed, feed is added to the interior of the screening tank (4) through the feed pipe (1). At this time, the built-in motor (11) is turned on to drive the centrifugal screening component (6) to rotate. Since a material shifting plate (7) is provided at the bottom of the top cover (2), the material shifting plate (7) can automatically shift the feed, and due to the centrifugal force of the rotation, the screened feed will be discharged through the two sides and the bottom of the centrifugal screening component (6); S2. In the above process, the driven wheel (82) can rotate along with the centrifugal screening cover (61), and the beating blade (83) can beat the thrown feed to make it evenly distributed.
