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.

The invention discloses an automatic receiving and transferring device for a pneumatic material conveying system. The automatic receiving and transferring device is connected to a pneumatic conveying pipeline unit used for conveying objects to be conveyed and comprises a cabinet body, and a receiving and transferring pipeline, a supporting and lifting platform unit and a manipulator unit are arranged inside the cabinet body; the upper end of the receiving and transferring pipeline is used for communicating with the pneumatic conveying pipeline unit; the supporting and lifting platform unit is matched with the receiving and transferring pipeline, does lifting motion below the receiving and transferring pipeline and is used for lifting the objects to be conveyed upwards, conveying the objects to be conveyed into the receiving and transferring pipeline for pneumatic conveyance and used for falling down after receiving the objects to be conveyed from the receiving and transferring pipeline; and the manipulator unit is arranged on one side of the lifting platform unit and is used for placing the objects to be conveyed from the exterior of the cabinet body on the lifting platform unit for lifting the objects and conveying the objects pneumatically and used for placing the objects to be conveyed on the lifting platform unit outside the cabinet body. The automatic receiving and transferring device has the advantages that the structure is simple and compact and the automation degree is high.

The invention relates to the technical field of food detection and in particular relates to a food security detector which comprises a conveying mechanism, a fixing support plate, a detection shell, adetection mechanism, a transmission mechanism, an extraction mechanism and a control mechanism, wherein the detection shell and the detection mechanism are connected with the conveying mechanism. Sampling and detection can be implemented at any time at any place according to production. Sampling can be achieved through the conveying mechanism and the extraction mechanism, a sample can be fed intothe detection shell for detection, completely automatic sampling can be achieved, manual sampling is not needed, and relatively convenient and safe sampling can be achieved. In the sampling process,sampling is controlled through the control mechanism, all samples are highly precise and highly average, and sample detection accuracy can be thus ensured. When the sample is detected, a user operatesinside the detection shell through an observation window and an extension sleeve, so that relatively good security can be achieved, and the sample can be prevented from external contamination.

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.
