In the transport state, the second fixed ear plate 23 is detachably and fixedly connected with the first fixed ear plate 11; in the weighing state, the support column 4 is pressed on the weighing sensor 5; when changing the state, the jack 7 is used for adjusting the vertical distance between the weighing frame 2 and the pry seat 1. The transportation state refers to the state of the weighing device in the transferring process, and the weighing state refers to the state of the weighing device in normal working and standby on site.
After the weighing and metering device is transported to the site, the transportation state is required to be changed into a weighing state, and a certain gap is formed between the lower surface of the weighing frame 2 and the pry seat 1 in the weighing state as shown in fig. 2. The process of changing state is as follows: firstly, the connection between the second fixed ear plate 23 and the first fixed ear plate 11 in the transportation state (see fig. 1) is disassembled, so that the weighing frame 2 can move upwards relative to the pry seat 1; then the telescopic rod of the jack 7 is ejected downwards, and the weighing frame 2 is lifted for a certain distance under the action of the jack 7, so that a certain gap is formed between the lower surface of the weighing frame 2 and the prying seat 1; then the lower end of the support column 4 is propped against the weighing sensor 5, and the support column 4 is fixed with the weighing frame 2; finally, the telescopic rod of the jack 7 is retracted upwards, so that the whole weight of the weighing frame 2 and the storage tank 3 is only supported by the weighing sensor 5.
