3results about How to "Guaranteed weighing accuracy" patented technology

This utility model discloses an automatic weighing and pensing device for livestock and veterinary use, comprising: a pensing frame with cleaning openings on the lower part of its two side surfaces; an electronic platform scale installed inside the lower end of the pensing frame; a weighing instrument installed at the center of one end of the pensing frame; a zeroing button installed on the vertical frame at one end of the pensing frame; a pensing ramp installed at one end of the pensing frame, with guardrails installed at both ends of its upper surface, one of which has an input panel installed; and a retractable gate mechanism located at the four corners inside the pensing frame. This utility model utilizes the retractable gate mechanism to avoid touching livestock and causing stress, while optimizing space design and reducing the occupied area. Furthermore, the automatic zeroing of the weighing when the gate is opened effectively ensures weighing accuracy and reduces errors. The input panel allows for the associated storage of weighing data for refined livestock management.

This invention discloses a tunnel boring machine (TBM) spoil weighing system. By setting up a wireless data collector and multiple weighing components, this invention realizes online measurement of spoil weight and transmits the data to the TBM control system in real time. This allows the TBM to dynamically adjust tunneling parameters based on the amount of spoil produced, improving the level of automation and intelligence in construction. The weighing components use pressure sensors and triggering components. During spoil transportation, the weight of the truck bed is no longer applied to the pressure sensors, avoiding long-term pressure on the sensors and causing elastomer fatigue, thus extending the sensor's service life and ensuring weighing accuracy.

This invention relates to an automatic weighing system for piezoelectric ceramic synthesis in high-throughput equipment, belonging to the field of weighing device technology. It includes a support platform with a collector at its center. Several weighing units are arranged around the collector on the support platform. Each weighing unit includes a discharge chute arranged in a V-shape, with its outlet extending above the collector. A hopper is connected above the discharge chute. This invention solves the problems of traditional technologies where piezoelectric ceramic powder is prone to agglomeration, leading to uneven material distribution due to the screw conveyor method, which is suitable for weighing large quantities of materials but not for weighing small amounts of additives and is prone to cross-contamination; and the inability to simultaneously weigh small doses of additives and large doses of powder, resulting in poor dosage compatibility of the weighing equipment.
