DETAILED DESCRIPTION

[0026] In order to make the structure and characteristics as well as the effectiveness of the present invention to be further understood and recognized, the detailed description of the present invention is provided as follows along with embodiments and accompanying figures.

[0027] The present invention provides a structure of material feeding device, which adopts a material feeding member spinning in the material feeding silo. By using mechanical stirs, the bridging phenomenon of materials can be destroyed. The conveying device is connecting two material feeding silos, two screw feeders, a pipe, and two sealing valves which can avoid contamination on materials. The present invention can improve various drawbacks in the prior art, and hence providing a more economical and practical structure to meet users' requirements.

[0028] Please refer to FIG. 1 and FIG. 2. FIG. 1 shows a schematic diagram of the structure according to the present invention; FIG. 2 shows a structural schematic diagram according to the first embodiment of the present invention. As shown in the figures, a material feeding device 100 is a structure for avoiding material obstruction. It comprises a first material feeding silo 10, a material feeding member 12, a first screw feeder 20, a second material feeding silo 30, a pipe 40, a second screw feeder 50, and a vessel 60. Materials can be poured into the first and second material feeding silos 10, 30 for temporary storage. The material feeding member 12, the first screw feeder 20, and the second screw feeder 50 include spiral blades and a spin shaft for conveying materials. The pipe 40 includes a first sealing valve 41 and a second sealing valve 42 for ensuring tight sealing of materials and avoiding contamination.

[0029] The shape of the first material feeding silo 10 is shown in FIG. 2. A main part 10a includes a diameter D1 and is barrel-shaped. The shape of the base blade can be, but not limited to, a circle or a rectangle. A material feeding part 10b is disposed below the main part 10a. The diameter of the material feeding part 10b shrinks from the top, which has a diameter D2, to the bottom, which has a diameter D3, and forming a diameter narrowing region 14. The diameter D3 is made to be smaller than the diameter D1, such that materials can be guided to slide downward. Please refer to FIG. 1. A material feeding member 12 is disposed inside the first material feeding silo 10. A motor 11 is adopted to drive the material feeding member 12 to spin. The material feeding member 12 includes a shaft 12a. A plurality of material feeding blades 12b are disposed at the end of the shaft 12a. The material feeding blades 12b are disposed at the diameter narrowing region 14 of the first material feeding silo 10 and located inside a first opening 13 at the bottom. Please refer to FIG. 3, which shows a schematic diagram of another shape of the first material feeding silo 10. As shown in the figure, the first material feeding silo 10 can be a cone-shaped structure with a diameter shrinking from D1 at the top to D3 at the bottom. Besides, please refer to FIG. 4, which shows a schematic diagram of the spiral of the material feeding blades according to the first embodiment of the present invention. As shown in the figure, alternatively, a spiral material feeding blades 12c can be disposed at the end of the shaft 12a.

[0030] The first screw feeder 20 is disposed at the first opening 13 of the first material feeding silo 10 and connected with the first material feeding silo 10. The first screw feeder 20 is connected with the side surface of the second material feeding silo 30. The second material feeding silo 30 includes a second opening 32, which is connected with the pipe 40. The pipe 40 includes the first sealing valve 41 at the top and the second sealing valve 42 at the bottom. The pipe 40 is connected with the second screw feeder 50. Finally, the second spiral material feeder 50 is connected with the vessel 60.

[0031] Next, pouring a first material 70 into the first material feeding silo 10. The material member 12 stirs mechanically for destroying bridging phenomenon of the first material 70. Then the first screw feeder 20 conveys the first material 70 to the second material feeding silo 30. Then pouring a second material 80 into the second material feeding silo 30 for mixing with the first material 70 and giving a mixed material 90. The mixed material 90 enters the pipe 40 from the first sealing valve 41 while the second sealing valve 42 is kept closed. After the mixed material 90 has reached a certain amount, the first sealing valve 41 is closed and the second sealing valve 42 is opened for conveying the mixed material 90 to the vessel 60 via the second screw feeder 50 and thus completing the conveying line of the present invention. In addition, the spin rates of the first and second screw feeders 20, 50 are both greater than the material feeding member 12. Thereby, the material feeding member 12 can control the spin rate of a plurality of material feeding blades 12b or spiral material feeding blades 12c by using the motor 11 and hence achieving the purpose of controlling material feeding rate.

[0032] Please refer to FIG. 5, which shows a schematic diagram of the material feeding member according to the second embodiment of the present invention. As shown in the figure, a material feeding member 12 is disposed inside the first material feeding silo 10. A motor 11 is adopted for driving the material feeding member 12 to spin. The material feeding member 12 includes a shaft 12a. A plurality of material feeding blades 12b are disposed at the end of the shaft 12a and at the junction 10c between a main part 10a and a material feeding part 10b of the first material feeding silo 10. Besides, please refer to FIG. 6, which shows a schematic diagram of the spiral material feeding blades according to the second embodiment of the present invention. As shown in the figure, alternatively, a spiral material feeding blades 12c can be disposed at the end of the shaft 12a. The locations and operations of the other components according to the second embodiment of the present invention are identical to those according to the first embodiment. Hence, the details will not be described again here.
