This invention discloses an automatic weighing device for micro-gram powders, relating to the field of micro-weighing technology. It includes a feeding structure, a subdivision structure, a weighing structure, and a container transfer structure arranged sequentially from top to bottom. The feeding structure includes a hopper with a first subdivision mesh at the hopper outlet. The first subdivision mesh has first mesh holes for powder to fall through, and a first driving structure drives a sealing plate to block and open the first mesh holes. The subdivision structure includes a subdivision space with a continuously oscillating second subdivision mesh at the subdivision inlet. A second driving structure drives a subdivision drum to rotate, and a third driving structure drives a container to tilt, pouring out the powder from the container. The container transfer structure includes a rotating lifting platform and a gripping robot mounted on the rotating lifting platform. Through the feeding structure, subdivision structure, weighing structure, and container transfer structure, automatic weighing and conveying of powders are achieved, thereby reducing manual labor intensity and improving work efficiency.

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 utility model discloses a simple ton bag packaging machine, including a frame and ton bags. A feeding pipe is provided at the center of the top of the frame. A dust removal fan is fixed on one side of the top of the frame to suck up the dust generated during the packaging process. Four weighing sensors are rectangularly distributed on the top of the frame, and the four weighing sensors are suspended by a weighing frame. The weighing frame in this utility model is connected to the pallet platform and a balance buffer assembly through four balance rods. The rubber pads abut against the fixed seat to absorb vibration impact, reduce interference to the weighing sensors when the pallet platform vibrator is working, and ensure weighing accuracy. The suspension design allows the weight to be fully borne by the weighing sensors. The balance rods and the buffer assembly form a "flexible connection", which not only ensures stable support of the ton bags, but also filters vibration energy through the elastic buffer of the rubber pads, thus solving the problem of "conflict between vibration compaction and weighing accuracy".

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 belongs to the field of bulk material conveying technology, and particularly relates to a weighing bulk material conveying device, including a conveyor frame and a conveyor belt disposed inside the conveyor frame, and further including: a weighing hopper located above one side of the conveyor belt, with weighing mechanisms disposed between the two sides of the weighing hopper and the two sides of the conveyor frame; and a discharge mechanism disposed at the bottom discharge port of the weighing hopper. This invention achieves precise weighing of sand and gravel through the weighing hopper and weighing mechanisms, ensuring the accuracy of concrete mix proportions; simultaneously, a buffer mechanism that adaptively adjusts based on weighing data effectively mitigates the impact of falling sand and gravel, reduces conveyor belt wear and malfunctions, and extends equipment life; furthermore, a dust collection mechanism whose power is adjusted in conjunction with the weighing value efficiently handles dust, and the purified gas can clean residual sand and gravel from the inner wall of the weighing hopper, reducing pollution and improving material utilization. Overall, it achieves a synergistic effect of precise metering, equipment protection, and environmental efficiency.

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.
