[0024] Reference Figure 3The inner wall of the material storage tube 10 is fixedly connected with a limit ring 11, and the interior of the limit ring 11 is slidably connected with a sealing plug 12; the outer wall of the sealing plug 12 is fixedly connected with a rubber ring 13, and the outer wall of the rubber ring 13 is slidably connected to the interior of the limit ring 11; the lower surface of the sealing plug 12 is fixedly connected with a connecting rod 14, and the bottom of the outer wall of the connecting rod 14 is fixedly connected with a sealing plug 2 15; the outer wall of the sealing plug 2 15 is slidably connected with a separating ring 16, and the outer wall of the separating ring 16 is fixedly connected to the inner wall of the material storage tube 10; the outer wall of the material storage tube 10 is provided with a fixing component; the fixing component includes a fixing block 17, and the outer wall of the fixing block 17 is fixedly connected to the outer wall of the material storage tube 10; the outer wall of the material storage tube 10 is fixedly connected with an electric push rod 18, and the outer wall of the electric push rod 18 penetrates into the interior of the fixing block 17, and the output end of the electric push rod 18 is fixedly connected with a connecting arc rod 19, and one end of the connecting arc rod 19 is fixedly connected to the lower surface of the sealing plug 2 15;

[0025] Specifically, the inner wall of the material storage tube 10 is connected to the limit ring 11, and the inner wall of the material storage tube 10 is connected to the sealing plug 12, so that the sealing plug 12 can be attached to the limit ring 11 to initially seal the material storage tube 10, and then the rubber ring 13 is connected to the sealing plug 12, so that the rubber ring 13 can further seal the sealing plug 12, and then the connecting rod 14 connects the sealing plug 12 and the sealing plug 2 15, so that the sealing plug 12 and the sealing plug 2 15 can move together, and then the electric push rod 18 is fixed to the outer wall of the material storage tube 10 by the fixing block 17, and the output end of the electric push rod 18 is connected to the connecting arc rod 19, so that the electric push rod 18 can drive the connecting arc rod 19 to move up and down, and then the connecting arc rod 19 is connected to the sealing plug 2 15, so that the electric push rod 18 can drive the sealing plug 12 and the sealing plug 2 15 to move up and down, thereby achieving a multiple sealing effect.

[0026] Working principle: when it is necessary to quantify the discharge amount, the cylinder 5 pulls the push plate 6 so that the feed hole 9 is aligned with the bottom of the feed pipe 2 for discharge. When a certain amount is reached, the cylinder 5 pushes the push plate 6 again so that the baffle 8 can separate the feed pipe 2 from the feed hole 9, blocking the feed pipe 2 from continuing to discharge. The limit block 7 inside the fixed ring 4 can limit the sliding distance of the push plate 6. When the baffle 8 completely blocks the feed pipe 2, the storage pipe 10 continues to discharge the material downward, thereby achieving the effect of quantitative discharge. When the storage pipe 10 needs to be fully sealed and discharged, the electric push rod 18 pulls the connecting arc rod 19, and then the connecting arc rod 19 pulls the sealing plug 15 to slide on the inner wall of the material storage tube 10. Since the sealing plug 12 and the sealing plug 15 are connected by the connecting rod 14, the sealing plug 12 can move with the sealing plug 15. When the sealing plug 12 is attached to the limiting ring 11 and the sealing plug 15 is attached to the separating ring 16, the material storage tube 10 can be completely sealed, thereby achieving the effect of fully sealing the material storage tube 10. On the contrary, the electric push rod 18 pushes the sealing plug 15 to drive the sealing plug 12 to slide downward, so that hollow spaces are formed between the sealing plug 12 and the limiting ring 11 and between the sealing plug 15 and the separating ring 16, thereby achieving the effect of fully discharging the material.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
