The utility model provides a quantitative proportioning device for producing a composite mineral admixture. The quantitative proportioning device for producing the composite mineral admixture comprises a box body, wherein the bottom of the box body is fixedly communicated with a discharge pipe; the storage box is arranged on one side of the box body, a plurality of partition plates are arranged in the storage box, and the storage box is divided into a plurality of storage cavities used for storing different raw materials by the partition plates; the automatic feeding mechanism is arranged on the box body and is used for pumping various raw materials into the box body in proportion; and the mixing mechanism is arranged on the box body and is used for mixing and stirring the raw materials. The quantitative proportioning device for production of the composite mineral admixture has the advantages that automatic feeding and mixing stirring of raw materials are achieved, production efficiency is improved, manual operation is reduced, labor intensity is lowered, and meanwhile proportioning errors caused by human factors are reduced.

This invention belongs to the field of petroleum coke production technology, and particularly relates to an integrated device for precise proportioning and homogenization of multiple raw materials for petroleum coke. The device includes: a base plate, a rotating frame fixedly installed on the top of the base plate, a mixing drum rotatably installed inside the rotating frame, a rotating rod rotatably installed inside the mixing drum, several stirring rods fixedly installed around the rotating rod, a guide nozzle fixedly installed on one side of the mixing drum, and a drive motor fixedly installed at the bottom of the mixing drum, the output end of the drive motor penetrating the bottom of the mixing drum and coaxially connected to the rotating rod; a power assembly located inside the rotating frame and used to drive the mixing drum to rotate; and a fixed frame fixedly installed on the top of the base plate and located on one side of the mixing drum. This invention allows for flexible adjustment of the total feed amount of corresponding raw materials by adjusting the rotation speed and frequency of the drive motor, achieving precise proportioning of multiple types of petroleum coke, ensuring consistency in the proportion of each batch of mixed materials, and effectively improving the stability of the finished coke's indicators.

This invention relates to a nutrient synergistic regulation system and control method for water-saving wheat cultivation, belonging to the field of wheat cultivation technology. The system includes: mapping soil moisture and nutrient content to a first feature vector; enhancing a wheat growth state image to obtain an enhanced growth state image; extracting a second feature vector from the enhanced growth state image using an image feature extraction network; fusing the first and second feature vectors to obtain a fused feature; inputting the fused feature into a deep learning model for training to obtain a wheat nutrient demand prediction model; and using the wheat nutrient demand prediction model to regulate the nutrients of the target wheat. This invention employs a random forest algorithm, an image feature extraction network, and a deep learning model, which can fully explore and learn the complex relationship between the soil environment and wheat growth state, more accurately reflecting the actual needs of wheat, achieving precise water and fertilizer ratios, and thus improving water and fertilizer utilization efficiency.
