Description

Technical Field

[0001] The utility model belongs to the technical field of weighing equipment, in particular to a medium-precision double-scale bulk material scale. Background Art

[0002] Bulk material scales are used for measuring bulk materials in a single way. When weighing heavier items, the weighing accuracy is average. If dual scales are used, accurate weighing cannot be guaranteed.

[0003] A search revealed a Chinese patent document (grant publication number CN207129178U) describing a novel bulk material scale device. The device comprises an upper buffer hopper, a first three-way solenoid valve, and a second three-way solenoid valve. The upper buffer hopper has a buffer dispensing port at its bottom. The first three-way solenoid valve divides the buffer dispensing port into two paths: a first branch and a second branch. The first branch is connected to a dust-free hopper with a discharge port at its bottom; the second branch is connected to a dispensing hopper with a dispensing outlet at its bottom. The second three-way solenoid valve divides the dispensing outlet into third and fourth branches. The device also includes a bulk weighing scale and a control mechanism, with both the first and second three-way solenoid valves connected to the control mechanism. Modifying the bulk material scale allows it to function as both a bulk material scale and a ton-bag scale, saving the cost of purchasing and maintaining a ton-bag scale. Bulk material scales are single-purpose weighing scales, and their accuracy is limited when weighing heavier items. Using dual scales would not guarantee accurate weighing. Utility Model Content
