2results about How to "Fast weighing" patented technology

This utility model relates to the technical field of weighing machines, providing a weighing machine including a coarse weighing mechanism, a fine weighing mechanism, and a weighing hopper. The coarse weighing mechanism includes a coarse material bin, a first conveying mechanism, and a volumetric bin. The first conveying mechanism is located inside the coarse material bin and is connected to the volumetric bin to convey coarsely weighed materials to the volumetric bin for coarse weighing. The weighing hopper is used to receive the coarsely weighed materials controlled and conveyed from the volumetric bin. The fine weighing mechanism includes a fine material bin, a second conveying mechanism, and a roller. The second conveying mechanism is located inside the fine material bin and is connected to the roller. The roller has multiple grooves for accommodating finely weighed materials. The controlled rotation of the roller pours the necessary finely weighed materials from the required grooves into the weighing hopper for fine weighing. This utility model achieves fast and accurate weighing through the volumetric bin and roller, and can also be used to weigh materials such as rice noodles and corn noodles.

The utility model discloses a concrete aggregate automatic metering and batching device, and belongs to the technical field of concrete production, the concrete aggregate automatic metering and batching device comprises a rack, a conveying belt is rotatably connected in the rack, fixing frames are arranged on the two sides of the rack, a transverse frame is arranged between the two fixing frames, and a plurality of aggregate storage hoppers are arranged in the transverse frame; a gate weighing mechanism is arranged at the bottom of the aggregate storage hopper and comprises a fixing plate, the fixing plate is located on one side of the aggregate storage hopper, a gate is rotationally connected to the middle of the fixing plate, a weighing module is arranged above the gate, and the gate abuts against the bottom of the aggregate storage hopper; when the device is used, the aggregate batching error can be effectively controlled, and the concrete strength consistency can be remarkably improved; the production efficiency is further improved, meanwhile, the automation level can be improved, and manual intervention is effectively reduced; the system is low in use cost and suitable for small and medium-sized mixing stations.
