[0030] Embodiment Three:
[0031] See Figure 4 and Figure 5 as shown
[0032] An accurate weighing and metering device for cement processing of the present utility model. The self-unloading cement weighing assembly includes a support table 200. Gravity transmitters 210 are fixedly installed at the four corners of the top of the support table 200. A first ear hook 221 is fixedly installed on the top of the outer wall of the bottom plate 220 away from the conical discharge end pipe 180. A second ear hook 231 is fixedly installed on the outer wall of the bottom of the weighing bin 230. The first ear hook 221 and the second ear hook 231 are rotatably connected through a shaft rod 232.

[0033] The specific use process of the utility model is as follows: When those skilled in the art use it, they import the cement to be weighed into the interior of the cement hopper 100. Under the action of gravity, the cement falls into the circular structure at the bottom of the cement hopper 100. Subsequently, by starting the servo motor 140, the servo motor 140 drives the rotation of the rotating shaft 131, so that the rotating shaft 131 can drive the rotation of the auger frame 160, enabling the auger frame 160 to convey the cement at the bottom of the cement hopper 100 to the feeding pipe 120. Subsequently, it is conveyed through the feeding pipe 120 to the conical discharge end pipe 180 and then conveyed to the weighing bin 230 through the cloth cylinder 181. The gravity driver 210 weighs the cement inside the weighing bin 230. After the required mass of cement is conveyed into the weighing bin 230, the servo motor 140 is turned off, causing the auger frame 160 to stop rotating. Subsequently, when it is necessary to bag the cement in the weighing bin 230 or discharge it into the cement transfer bin 300, by starting the hydraulic telescopic rod 260, the hydraulic telescopic rod 260 extends, pushing the weighing bin 230 to rotate around the shaft rod 232, causing the weighing bin 230 to tilt at a certain angle, so that the cement inside the weighing bin 230 can, under the action of gravity, be discharged through the discharge pipe 233 and the blanking pipe 234 into the bag or the cement transfer bin 300, thus completing the unloading of the cement in the cement transfer bin 300.
