The invention discloses a sample feeding device for iron and steel smelting with sampling function, belonging to the technical field of iron and steel smelting. A cylinder and a drive motor are fixedly installed on the outer wall of one side. In the present invention, through the provided first pulley and the cylinder, the driving motor is turned on, the rotating shaft installed at one end of the output shaft of the driving motor rotates, and the first pulley is driven to rotate, thereby driving the belt to rotate. On the inner wall, the belt rotates to drive the second pulley to follow. Under the control of the chip in the control panel, the cylinder works, and the cylinder rod installed in the cylinder drives the push plate to the sampling port, which is convenient for the staff to take samples without manual sampling. , high efficiency, and effectively solve the problem that the high temperature of steel products will cause serious burns to the sampling personnel, and the safety is low.

An intelligent grouting system is provided with a single chip microcomputer, a keyboard and a display. Pipelines provided with magnetic valves, sensors or electronic scales are inserted into a grout production barrel, wherein the pipelines are respectively loaded with water, cement powder, sand, a chemical additive, dense grout and so on therein; the proportioning and consumption of grout is controlled through programming, thus a grout proportioning efficiency is high, proportioning is accurate, and labor intensity is low. A frequency converter provided with a communication interface is added to a drive motor of a grouting pump, an input end of the single chip microcomputer is connected with a pressure sensor, an output end of the single chip microcomputer is connected with a high pressure valve and an alarm device; the power of the drive motor and the pressures of the pipelines are controllable, thereby saving electric energy; operating personnel are far away from the high-pressure pipes, thus security is achieved. A tension sensor of which an output end is connected with the single chip microcomputer is fixed over the grout production barrel, a metal weight immersed in cement grout is hanged on a lower end of the tension sensor; the single chip microcomputer continuously measures and displays the proportion, and adjusts the grout concentration in real time to ensure grouting quality, the frequency of cleaning is low. Through adoption of the intelligent grouting system, only grouting parameters need to be manually inputted, the subsequent operations such as grout proportioning and grouting are all automatically performed by the system, thereby saving time and labor. The intelligent grouting system is used for grouting construction of a hydropower station, especially at the places such as side slope and dam foundation.
