And by taking a certain amount of the finished product of each batch of processed additives in the detection concave plate 512 and sending it to the detection laboratory for detection, the practicability of this discharging device is effectively improved.

[0022] Working principle: In the present invention, an external controller is connected to the servo motor 31 and the vibration motor 42 for control. During use, by opening the discharge valve 7 outside the discharge pipe 6 and the vibration motor 42, the processed additive is discharged through the discharge pipe 6. The vibrating plate 43 with an inclined surface in the rectangular pipe 41 conducts discharge diversion. At the same time, the output end of the dynamic motor 42 transmits vibration waves to the vibrating plate 43. Through the vibration of the vibrating plate 43, it is convenient to vibrate the additive on the upper surface of the vibrating plate 43, effectively improving the discharge rate, avoiding blockage caused by discharge accumulation and affecting the discharge efficiency. And by setting a rubber pad 10 between the upper flange 8 and the lower flange 9, it effectively plays a shock-absorbing effect, preventing the vibration source from being transmitted to the discharge pipe 6 and the kettle body 1 at its upper end, and affecting the normal operation of the kettle body 1. And the output end of the servo motor 31 drives the rotating shaft 32 to rotate, and the rotating shaft 32 drives the first gear 33 to rotate. Then, the first gear 33 drives the rack 35 engaged with it to rotate. The rack 35 stably slides in the positioning groove 317 outside the first concave plate 34 through the positioning block 314, facilitating the rack 35 to stably drive the support rod 36 and its material guide plate 37 to move left and right. The inner cavity bottom end of the material guide plate 37 is an inclined surface, which is convenient for receiving the additive discharged from the rectangular pipe 41. Through the continuous left and right reciprocating movement of the material guide plate 37, the additive in the inner cavity of the material guide plate 37 is discharged from the right side of the material guide plate 37 and falls onto the filter mesh plate 583 in the filtering mechanism 5. And when the material guide plate 37 moves to the rightmost end, the material guide plate 37 is still below the rectangular pipe 41, preventing the inability to receive the discharge and resulting in abnormal discharge of the additive, effectively improving the use effect. And by discharging the additive through the material guide plate 37 with an inclined surface, it effectively utilizes the principle of free fall by weight, facilitating the additive to increase the discharge fluidity while the material guide plate 37 moves left and right reciprocally, increasing its discharge efficiency and effectively improving the use effect. When the output end of the servo motor 31 drives the rotating shaft 32 to rotate, the pulley 53 outside the rotating shaft 32 rotates synchronously. This pulley 53 drives another pulley 53 and the fixed shaft 52 in its inner cavity to rotate synchronously through the belt 54. Then, the two second gears outside the fixed shaft 52 drive the first tooth sleeve 582 and the second tooth sleeve 595 to rotate respectively. Then, the first tooth sleeve 582 and the second tooth sleeve 595 drive the first support seat 581 and the second support seat 591 to rotate respectively. The first support seat 581 is inserted into the insertion post 584 at the lower end of the filter mesh plate 583 through the insertion slot 585, facilitating the detachable installation of the filter mesh plate 583, convenient for disassembling, cleaning and replacing the filter mesh plate 583. And the filter mesh plate 583 rotates synchronously with the first support seat 581, and the additive discharged from the material guide plate 37 falls into the filter mesh plate 583. Through the rotation of the filter mesh plate 583, it is convenient to shake the additive falling on its upper end, avoiding the additive from accumulating in a straight line position at the upper end of the filter mesh plate 583 and causing filter blockage and affecting the filtering effect.Moreover, the rotation of the filter screen plate 583 effectively improves the filtration efficiency. At the same time, the second support base 591 is provided with a filter membrane 594 laid between the support frame 592 and the limiting ring 593, which is convenient for the support frame 592 to support it, and the limiting ring 593 limits it, effectively enabling the filter membrane 594 to be installed and disassembled easily. The filter membrane 594 also rotates with the second support base 591, effectively improving the efficiency of fine filtration. Finally, the filtered additive drops into the diversion plate 511, and through inclined diversion, the additive is finally discharged into the detection concave plate 512, and then discharged for packaging and shipment. By taking a certain amount of the finished product of each batch of processed additives in the detection concave plate 512 and sending it to the detection laboratory for detection, the practicability of this discharging device is effectively improved.
