[0023] like Figure 1 、 2 As shown, this embodiment provides a synchronous premixed feeding device, which includes a first feed pipe 1, the first feed pipe 1 is vertically arranged and a second feed pipe 2 is fixedly arranged around the outside of the first feed pipe 1, and a plurality of connecting holes 3 are opened on the outer wall of the first feed pipe 1 for connecting the inside thereof with the second feed pipe 2; the upper end of the first feed pipe 1 is also fixedly connected to a feed hopper 4 and a feeding motor 5 connected thereto, and the feeding motor 5 is connected to a mounting shaft 6, which rotates and extends into the first feed pipe 1 and is also fixedly surrounded by a conveying screw 7; the lower end of the first feed pipe 1 extends to the bottom of the second feed pipe 2 and is provided with a discharge port 8.

[0024] In the above embodiment, the first feed pipe 1 and the second feed pipe 2 respectively supply two materials, and when the feeding motor 5 is running, it drives the conveying screw 7 to run, and the material in the first feed pipe 1 is conveyed downward. At the same time, the material in the second feed pipe 2 can also enter the first feed pipe 1 through the connecting hole 3. The two materials are conveyed downward together, and finally the common feeding is realized, which shortens the overall feeding time and is provided with energy by a feeding motor 5, thereby solving the problem of long feeding time or high energy consumption in the prior art; specifically, after the material in the second feed pipe 2 enters the first feed pipe 1, it continues to be advanced by the conveying screw 7 so that the two materials can be pre-mixed, which can reduce the mixing load in the mixer and make the overall mixing efficiency better.

[0025] like Figure 1 、 2 As shown, in a further scheme, a guide ring 9 is fixedly connected between the lower end of the second feed pipe 2 and the first feed pipe 1, and a connecting hole 3 is provided at the connection between the guide ring 9 and the first feed pipe 1, wherein the outer ring of the guide ring 9 is higher than its inner ring, so that the material in the second feed pipe 2 can move more smoothly toward the provided connecting hole 3, and when the conveying screw 7 is running, negative pressure will be generated on the side of the first feed pipe 1 at the connecting hole 3, thereby smoothly conveying the material in the second feed pipe 2 to the first feed pipe 1, and finally realizing joint feeding.

[0026] like Figure 1As shown, the upper end of the second feed pipe 2 is fixedly connected to a guide cylinder 10 with a larger upper end and a smaller lower end, and an annular opening 11 surrounding the outside of the first feed pipe 1 is provided above the guide cylinder 10. The annular opening 11 allows the material to smoothly enter the guide cylinder 10 and then enter the second feed pipe 2; in more detail, the upper end of the first feed pipe 1 is fixedly connected to a charging cylinder 12, and the feeding motor 5 and the feeding hopper 4 are fixed on the charging cylinder 12. The charging cylinder 12 is similar to the guide cylinder 10, and allows the material to transition to the first feed pipe 1, and also provides an installation basis for the feed hopper 4 and the feeding motor 5.

[0027] like Figure 1 As shown, further, a number of support rods 13 equidistantly surrounding the outside of the first feed pipe 1 are fixedly connected between the lower end of the guide cylinder 10 and the charging cylinder 12, that is, the support rods 13 provide a fixed connection basis between the first feed pipe 1 and the second feed pipe 2 at the upper end, so that the two can be fixed more stably. In more detail, a support ring 14 is fixedly connected to the outside of the upper end of the first feed pipe 1, and all support rods 13 are fixedly connected to the support ring 14 respectively. The support rods 13 are tilted, and the lower end is connected to the guide cylinder 10 and the higher end is connected to the support ring 14. The support rods 13 realize the supporting effect and will not block the material from smoothly entering the second feed pipe 2; at the same time, all the connecting holes 3 are located below the support rods 13, and the conveying screw 7 extends into the charging cylinder 12. When the conveying screw 7 is running, it can smoothly drive all the connecting holes 3 to allow the material in the second feed pipe 2 to smoothly enter and be introduced into the first feed pipe 1.

[0028] like Figure 1 As shown, a connecting rod 15 can be fixedly connected to the material guide cylinder 10 to assist in connecting the device to the mixer, and the discharge port 8 at the lower end of the first conveying pipe can be connected to the feed port of the mixer, thereby smoothly realizing the mixing and feeding of the mixer.
