[0030] Working principle and effect: The outer collar 4 is rotatably connected to the feed bin 3. When the second feed port 41 is aligned with the first feed port 31 and the second discharge port is aligned with the second discharge port, the raw materials are poured into the feed bin 3 through the first feed port 31 and the second feed port 41, and the raw materials will slide toward the first discharge port and the second discharge port along the first inclined surface 33, and slide into the upper hopper 22 through the guide plate 43; then, the outer collar 4 is rotated so that the inner wall of the outer collar 4 blocks the first feed port 31 and the first discharge port. At the same time, the guide plate 43 will also rotate with the outer collar 4 to avoid blocking the upper hopper 2 2 rises; start the lifting assembly, the screw rod 11 rotates clockwise, thereby driving the connecting block to move upward along the screw rod 11 and the slide rod 12, thereby driving the upper hopper 22 to rise until it rises to the top and stops rising; start the flipping assembly, and rotate the rotating rod 21 to drive the upper hopper 22 to flip, thereby pouring the raw materials in the upper hopper 22 into the mixing tank, thereby completing the loading and unloading; finally, the upper hopper 22 is reset by rotating the rod 21, and the upper hopper 22 is lowered by rotating the screw rod 11 counterclockwise, and the outer collar 4 is rotated to make the guide plate 43 located above the upper hopper 22, and the loading action is performed.

[0031] Compared with the existing technology, the UHPC premix raw material feeding device provided in this application adopts the cooperation of a lifting component, a flip component and a feeding component to realize automatic mechanized feeding, replacing the traditional manual handling and feeding, reducing the labor intensity and effectively improving the feeding speed.

[0032] In one embodiment, Figure 4 As shown, the guide plate 43 is provided with a second inclined surface 431, which is an extension of the first inclined surface 431. To prevent the raw materials from remaining on the guide plate 43, the second inclined surface 431 is provided on the guide plate 43. The second inclined surface 431 is an extension of the first inclined surface 33. That is, the inclination angle and direction of the second inclined surface 431 are the same as those of the first inclined surface 33, so that the raw materials can slide completely into the upper hopper 22.

[0033] In one embodiment, Figure 1 or Figure 2As shown, the lifting assembly also includes a base 1 and a top plate 14. The bottom end of the sliding rod 12 is mounted on the base 1, and the top end of the sliding rod 12 is mounted on the top plate 14. The bottom end of the screw rod 11 is rotatably connected to the base 1, and the top end of the screw rod 11 is rotatably connected to the top plate 14. A first drive motor 15 is provided on the top plate 14, and the output end of the first drive motor 15 is connected to the screw rod 11. The base 1 is used to mount the sliding rod 12 and the screw rod 11, and the top plate 14 is used to fix the top ends of the sliding rod 12 and the screw rod 11. The first motor is fixedly mounted via the top plate 14. The bottom end of the screw rod 11 is rotatably connected to the base 1 via a bearing, and the top end of the screw rod 11 is rotatably connected to the top plate 14 via a bearing. The top plate 14 can also serve as a limiter to prevent the moving block 13 from moving and falling out of the top of the sliding rod 12.

[0034] In one embodiment, Figure 2 or Figure 3 As shown, the connecting frame 2 includes a horizontal plate 23 and two side plates 24. The two side plates 24 are respectively mounted at the ends of the horizontal plate 23, forming a U-shaped structure, and the opening of the U-shaped structure is set upward. The ends of the rotating rod 21 are respectively rotatably connected to the inner walls of the two side plates 24. A second drive motor 25 is mounted on the outer wall of one side plate 24, and the output end of the second drive motor 25 is rotatably connected to the rotating rod 21. The connecting frame 2 is configured as a U-shaped structure including the horizontal plate 23 and the two side plates 24, so that the two side plates 24 are used to mount the rotating rod 21, and the horizontal plate 23 is used to connect the two side plates 24. The opening of the U-shaped structure is set upward, so that the rotating rod 21 can drive the upper hopper 22 to flip and discharge materials.

[0035] In one embodiment, Figure 2 As shown, a connecting plate 26 is provided on the rotating rod 21, and the upper hopper 22 is mounted on the connecting plate 26. The connecting plate 26 is used to connect the rotating rod 21 and the upper hopper 22, and the connecting plate 26 is provided so that the upper hopper 22 is located at the bottom of the guide plate 43, so as to receive the raw materials sliding out from the second discharge port.

[0036] In one embodiment, Figures 2 to 3As shown, the feeding assembly is mounted on the base 1, and a rotating assembly is provided on the base 1. The lifting assembly and the rotating assembly are respectively located on both sides of the feeding assembly. The rotating assembly includes a support column 5, and a mounting plate 51 is provided on the top of the support column 5. A third drive motor 52 is installed on the mounting plate 51. The output end of the third drive motor 52 is connected to a rotating gear 53. An annular rack 46 is provided at the bottom of the outer wall of the outer collar 4. The rotating gear 53 and the annular rack 46 are meshed together. The rotating assembly is used to drive the outer collar 4 to rotate. Specifically, the rotating gear 53 is driven to rotate by the third drive motor 52, and the rotating gear 53 is meshed together with the annular rack 46 at the bottom of the outer wall of the outer collar 4, so that the outer collar 4 rotates under the drive of the rotating gear 53. When the raw material slides into the upper hopper 22 from the guide plate 43 and the upper hopper 22 is full, the third drive motor 52 is started to rotate the outer collar 4, thereby rotating the guide plate 43 to the oblique upper part of the upper hopper 22 (as shown in FIG. 1 ). Figure 3 As shown), the guide plate 43 is prevented from blocking the rise of the upper hopper 22. At the same time, the outer collar 4 rotates to offset the second discharge port, and the inner wall of the outer collar 4 rotates to the original position of the second discharge port to block the first discharge port, preventing the raw material from continuing to slide out of the first discharge port.

[0037] In one embodiment, Figure 1 or Figure 4 As shown, a dust shield 45 is provided on the top of the second feed port 41. The feed bin 3 can be fed manually by pouring the raw materials into the feed bin 3 from the first feed port 31 of the feed bin 3. In order to prevent dust generated by the raw materials from being blown upwards when pouring, a dust shield 45 is provided above the first feed port 31.
