When the lower pipe 3 transports the material into the batching rack 5, the weight is detected by the four pressure weighing sensors 63, and the measured data is transmitted to the external controller. The external controller calculates the average weight according to the four pressure weighing sensors 63, and then controls the opening and closing of the discharge valve 4 according to the weighed data.

[0021] like Figure 3 and Figure 4As shown in the figure, the batching rack 5 includes a batching rack body 51, and a discharge pipe 52 is integrally formed at the bottom of the batching rack body 51. A bevel inclined toward the discharge pipe 52 is arranged in the batching rack body 51. The inclined arrangement facilitates the batching rack body 51 to discharge materials into the discharge pipe 52. A discharge assembly 7 is embedded and assembled in the discharge pipe 52.

During the batching process, the discharge valve 4 in the discharge pipe 3 is controlled to be opened and closed according to the weight proportion of each raw material, and the batching operation is performed on each raw material. The specific process is that in the initial state, there is no raw material in the batching rack 5. At this time, the weight data detected by the pressure weighing sensor 63 is the state when the batching rack 5 is not put into the material. One of the four silos 2 is opened, and the material is discharged into the batching rack 5 through the discharge pipe 3. The weight data of the material discharge process is obtained by the pressure weighing sensor 63. When the unloading requirement is met, the unloading valve 4 is controlled to close. At this time, the external controller records the weight data again, and then opens the unloading pipe 3 of the next silo 2. The above operation is repeated to complete the unloading of materials of different weights in the four silos 2 in turn as required. After the unloading of the four silos 2 is completed, the output end of the hydraulic telescopic cylinder 72 in the discharging component 7 is controlled to rise, and the hydraulic telescopic cylinder 72 drives the lifting frame 73 and the conical block 74 to rise. The material in the batching rack 5 is slowly moved to the surface of the conveyor belt of the conveying equipment below through the discharging pipe 52, and the raw materials are fully mixed by the conveyor belt, which is originally transported to the mixing equipment for subsequent processing.
