In order to solve the problems, the technical scheme is designed one by one and planned comprehensively, and the technical scheme of the embodiment of the invention is further elaborated by combining the drawings of the invention.

Example 1:

referring to fig. 16, a high precision smelting system for transporting raw and auxiliary materials to a smelting furnace 70 includes: a raw material station 10 for holding raw materials; the raw material station 10 is partitioned into a plurality of spaces in which raw materials are contained, and the same raw material is divided into at least one of large blocks, medium blocks and small blocks by mass and is placed in different spaces, respectively. A raw material transfer device 20 for transferring raw materials from the raw material station 10 to an intermediate weighing device 50; an auxiliary material station 30 for containing auxiliary materials; an auxiliary material transferring device 40 for transferring the required auxiliary materials from the auxiliary material station 30 to the raw and auxiliary material transport vehicle 60; the centralized weighing device 100 is used for containing and weighing the raw materials transferred by the raw material transferring device 20 until the raw material quality reaches the required quality, and/or containing the auxiliary materials transferred by the auxiliary material transferring device 40, and transferring the required raw materials and/or the required auxiliary materials to the smelting furnace 70.

It can be seen that the function of the centralized material weighing device 100 can be finished by only adding the floor scale on the original basis, the centralized material weighing device 100 is added, the original electromagnetic chuck 23 absorbs the materials after weighing each time, the materials are added into the material conveying trolley, the error of N times of accumulated weighing is superposed, the weighing error is large, the problem that the current electromagnetic chuck 23 places the materials after weighing each time into the centralized material weighing device 100, the centralized material weighing device 100 is used for one time, no accumulated error exists, the bearing error is reduced, and the raw material precision is improved.

Example 2:

in practical production, the raw materials are relatively heavy and are quite large, and are often loaded by a large truck and poured into pits, so that the raw materials are not arranged in matrix rows for facilitating feeding, but are arranged in a manner of being beneficial to unloading of the truck, so that the long axis direction is always provided, and sometimes, 20 raw material pits are large, the raw material pits are generally ten meters wide, so that the long axis direction of the raw material station 10 is still quite long, the centralized weighing device 100 is arranged at one end, and a lot of time can be spent in the material taking process of the raw material transferring device 20.

On the basis of embodiment 1, the raw and auxiliary material transporting vehicle 60 moves along the long axis direction of the raw material station 10, and the mass sensing device 100 matched with the raw and auxiliary material transporting vehicle 60 is disposed along the long axis direction of the raw material station 10. In this way, the raw and auxiliary material transport vehicle can move along with the raw material transfer device, so that the raw material transfer device 20 adsorbing raw materials can reach the raw and auxiliary material transport vehicle 60 in the nearest path, and the loading rate is improved.

Example 3:
