Abstract: A gas extraction device for metal mineral inclusions and a gas extraction method therefor are provided, the device includes a base plate, an annular carrier, sealing covers, a grinding assembly, a vacuum assembly, a gas-gathering assembly and a mass spectrometer. The annular carrier is disposed on the base plate, multiple grinding chambers are defined and evenly distributed in a circular shape on the annular carrier, the sealing covers are disposed at openings of the grinding chambers, the grinding assembly includes grinding hammers, and the grinding hammers penetrate through the sealing covers and extend into the grinding chambers. Side walls of each grinding chamber defines a first through hole and a second through hole. The vacuum assembly is communicated with the grinding chambers through the first through holes. The gas-gathering assembly is communicated with the grinding chambers through the second through holes. The mass spectrometer is communicated with the gas-gathering assembly.

Abstract: A process for processing a rotary tillage blade for a dry farmland based a wasted steel rail is provided. The process specifically includes the following steps: selecting a waste annotated steel rail U71Mn or U75V; breaking the steel rail into a rail head, a rail web and a rail bottom in a cutting area by means of a flame cutting device and then cutting the steel rail; and applying a hydrostatic pressure to the steel rail by using a hydraulic machine to separate the rail head, the rail web and the rail bottom. The wasted steel rail can be processed into the rotary tillage blade for the dry farmland by means of methods such as segmenting, rolling, blanking, punching, electric furnace heating, bending, hot forging and thermal treatment. The surface hardness and a wear resistance value thereof are superior to those of an existing rotary tillage blade.
