Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 , This embodiment provides a technical solution: a solid feed additive screening and filtering device, including a screening table 1 and a reciprocating drive mechanism 5;

[0021] Screening table 1: a screening table 2 2 is arranged at its upper end, a movable screening bucket 3 is arranged inside the screening table 1, a movable inclined screening bucket 4 is arranged inside the screening table 2, an inclined discharge plate 13 is fixedly connected inside the screening table 1, a feed bin 12 is fixedly connected to the upper end of the screening table 2 2, and a discharge bucket 9 is arranged at the front end of the inclined screening bucket 4;

[0022] Reciprocating drive mechanism 5: It includes a motor frame 51, a drive shaft 53, a cam 54, a connecting rod 55, a drive column 56, a support plate 57 and a drive wheel 58. The motor frame 51 is fixedly connected to the front end of the left side surface of the screening platform 1, and the rear end of the motor frame 51 is rotatably connected to the drive shaft 53. The right end of the drive shaft 53 is fixedly connected to the cam 54. The distal end of the right side surface of the cam 54 is fixedly connected to the connecting shaft. The middle part of the connecting shaft is rotatably connected to the connecting rod 55. The drive column 56 is fixedly connected to the middle part of the left side surface of the screening bucket 3. The middle part of the drive column 56 is rotatably connected to the upper end of the connecting rod 55. The lower end of the screening bucket 3 is fixedly connected to the support plates 57 that are symmetrically distributed. The lower ends of the support plates 57 are all provided with drive wheels 58. The lower ends of the driving wheels 58 are mounted in cooperation with the upper ends of the inclined screening buckets 4. The reciprocating driving mechanism 5 also includes a motor 52. The motor 52 is arranged at the rear end of the left surface of the motor frame 51. The output shaft of the motor 52 is fixedly connected to the left end of the driving shaft 53. The input end of the motor 52 is electrically connected to the output end of the control switch 14. The operation of the motor 52 is realized by the control switch 14. The rotation of the output shaft of the motor 52 drives the driving shaft 53 to rotate, and then drives the cam 54 to rotate. The rotation of the cam 54 drives the front end of the connecting rod 55 to rotate around the central axis of the driving shaft 53 through the connecting shaft. When the front end of the connecting rod 55 rotates forward, the rear end of the connecting rod 55 pulls the screening bucket 3 forward through the driving column 56, and slides at the same time. The wheels 11 all slide forward in the corresponding chute 10, providing a limit and guide function for the sliding of the screening bucket 3. When the front end of the connecting rod 55 rotates backward, the rear end of the connecting rod 55 pushes the screening bucket 3 forward through the driving column 56. At the same time, the sliding wheels 11 all slide backward in the corresponding chute 10. With the rotation of the cam 54, the screening bucket 3 makes a back and forth reciprocating motion. While realizing the primary screening of the solid feed additives, the solid feed additives entering through the feed hopper 12 are evenly scattered into the interior of the screening bucket 3, accelerating the primary screening rate of the solid feed additives. The solid feed additives after the primary screening fall into the interior of the inclined screening bucket 4, and the impurities stay in the interior of the screening bucket 3. When the screen bucket 3 moves backward, the driving wheel 58 moves backward, and the thrust of the driving wheel 58 applied to the inclined surface of the inclined screen bucket 4 is reduced. The elastic force of the spring 8 pushes the vertically adjacent sliding seat 7 upward, thereby causing the inclined screen bucket 4 to move upward. As the screening bucket 3 moves back and forth horizontally, the inclined screen bucket 4 makes a vertical reciprocating motion, thereby realizing secondary screening of solid feed additives.

[0023] Wherein: the left and right ends of the screening table 2 are provided with a chute 10, the left and right ends of the screening bucket 3 are fixedly connected with a sliding wheel 11, and the two longitudinally adjacent sliding wheels 11 are slidably connected to the same chute 10;

[0024] Among them: evenly distributed pillars 6 are fixedly connected between the screening table 1 and the screening table 2, the middle part of the pillars 6 is slidably connected with a sliding seat 7, the end of the sliding seat 7 close to the center of the screening table 1 is fixedly connected to the inclined screening bucket 4, the sliding seat 7 and the screening table 1 are fixedly connected with a spring 8, and the spring 8 is movably sleeved on the outer surface of the longitudinally adjacent pillars 6.

[0025] The working principle of the solid feed additive screening and filtering device provided by the utility model is as follows: when working, the personnel first stably place the screening table 1 and the screening table 2 and other mechanisms in the working area, and after the placement is stable, the personnel add the solid feed additive to be screened and filtered into the inside of the screening bucket 3 through the feed hopper 12, and at the same time realize the operation of the motor 52 through the control switch 14, the output shaft of the motor 52 rotates to drive the driving shaft 53 to rotate, and then drives the cam 54 to rotate, and the rotation of the cam 54 drives the front end of the connecting rod 55 to rotate around the central axis of the driving shaft 53 through the connecting shaft When the front end of the connecting rod 55 rotates forward, the rear end of the connecting rod 55 pulls the screening bucket 3 forward through the driving column 56, and the sliding wheels 11 slide forward in the corresponding chute 10, providing a limit and guide for the sliding of the screening bucket 3. When the front end of the connecting rod 55 rotates backward, the rear end of the connecting rod 55 pushes the screening bucket 3 forward through the driving column 56, and the sliding wheels 11 slide backward in the corresponding chute 10. With the rotation of the cam 54, the screening bucket 3 reciprocates back and forth, realizing the primary screening of the solid feed additives while allowing the solid feed additives entering through the feed hopper 12 to be screened. The solid feed additives are evenly scattered into the interior of the screening bucket 3, accelerating the primary screening rate of the solid feed additives. The solid feed additives after primary screening fall into the interior of the inclined screening bucket 4, and the impurities stay in the interior of the screening bucket 3. When the screening bucket 3 moves forward, it drives the two supports 57 to move forward. The forward movement of the supports 57 drives the vertically adjacent driving wheels 58 to move forward. The driving wheels 58 contact the inclined surface of the inclined screening bucket 4, pushing the inclined screening bucket 4 to move downward. At the same time, the moving seats 7 slide downward on the outer surface of the corresponding pillars 6. The downward movement of the sliding seats 7 causes the vertically adjacent springs 8 to be elastically compressed. When the screening When the bucket 3 moves backward, the driving wheel 58 moves backward, and the thrust applied by the driving wheel 58 to the inclined surface of the inclined screening bucket 4 is reduced. The elastic force of the spring 8 pushes the vertically adjacent sliding seat 7 to move upward, thereby causing the inclined screening bucket 4 to move upward. As the screening bucket 3 moves back and forth horizontally, the inclined screening bucket 4 makes a vertical reciprocating motion to achieve secondary screening of the solid feed additives. The solid feed additives after the secondary screening fall into the upper end of the inclined discharge plate 13. The impurities after the secondary screening and some solid feed additives are removed through the discharge hopper 9, and then slide backward under the action of gravity to enter the next working area.

[0026] It is worth noting that the motor 52 disclosed in the above embodiment can be a 25-214F15A AC permanent magnet synchronous servo motor, and the control switch 14 is provided with a control button corresponding to the motor 52 and controlling its switch.
