Description

Technical Field

[0001] The present invention relates to the technical field of hopper load-bearing, and in particular to a base installation device for convenient disassembly of a weighing sensor and a method for using the same. Background Art

[0002] In order to improve the proportion accuracy and mixing efficiency of the mixture, a hopper with a weighing sensor device has emerged. This hopper allows the user to further understand the weight of the discharged material by understanding the weight change of the material in the current hopper. However, most of the weighing sensors are currently fixed directly between the hopper and the bracket. The weighing sensor is a measuring tool and needs to be calibrated and tested regularly. It needs to be removed during testing. The sensor of the existing structure is not convenient to disassemble, and the upper material hopper needs to be completely removed.
