The present application relates to the technical field of dry separator rejection, in particular to a flexible rejection device and method for underground coal mine dry separator, which is installed at the tail of the dry separator and used for separating and rejecting the gangue and coal recognized by the dry separator to two parallel conveyer belts under the discharge device; the device comprises side plates on the left and right sides; the side plates are fixed on the support; the inner side of the two side plates is drivingly connected with a transmission roller at the upper position; the outer wall of the transmission roller is drivingly connected with a transmission belt; a nozzle is arranged below the transmission belt; a plurality of nozzles are uniformly distributed in the left-right direction; the nozzles can change the spray angle and direction under control; a push plate is arranged below the nozzles; the present application integrates the two different rejection mechanisms of nozzle blowing and push plate rejection in the same rejection device, and realizes the linkage of the structure and the adjustment of the posture, so as to realize flexible rejection according to the particle size characteristics of the coal gangue and achieve the purpose of efficient separation of underground coal gangue of all particle sizes.

The utility model provides a kind of steel structure engineering quality nondestructive testing device, including base, steel structure positioning seat, the top of the base is detachably connected with steel structure positioning seat, the two corners of the top surface of the base are fixedly connected with track, the track is movably connected with slider, the height of the slider, rotation angle can be adjusted, the side surface of the slider is threadedly connected with fastening pin.The utility model has the advantages that the detection end of dial gauge is used to detect the flatness of the surface of steel structure sample, the angle of dial gauge is adjustable, the height of slider structure loading dial gauge is adjustable, and the detection structure (track, slider, fastening pin, main shaft, main plate, dial gauge, fastener) is installed at the two corners of base, so that different surfaces of steel structure sample can be detected simultaneously, the detection efficiency is high, the posture of dial gauge is adjustable, the vertical surface and inclined surface of different shape and special-shaped steel member sample can be detected for flatness, and the utility model is flexible to use.

The invention discloses an SMA-driven multi-degree-of-freedom intelligent electric wrench, which relates to the technical field of fastening and dismounting tools, and is provided with a variable caliber unit D comprising a folding and unfolding assembly, an SMA spring, a heat conducting strip, a mounting rod and a radiator; the mounting rod sleeves the transmission shaft, and the front end of the mounting rod is fixedly mounted with the handle; the radiator is fixedly installed on the installation rod in the circumferential direction of the installation rod, the folding and unfolding assembly is connected with the rear end of the transmission shaft through the center shaft, the motor drives the folding and unfolding assembly to rotate around the axis of the center shaft in a fixed-axis mode, and the SMA spring is electrically communicated with the power source and communicated with the radiator through the heat conduction strip for heat exchange. The folding and unfolding assembly can be folded or unfolded under the action of the SMA spring, at least three corners are always kept to be unfolded, inner hexagonal threaded parts with different calibers can be fastened and disassembled under the condition that the assembly is not replaced, the portability and the working efficiency of the inner hexagonal wrench are greatly improved, and the inner hexagonal wrench is simple in structure, light, efficient, environmentally friendly and suitable for popularization and application. And meanwhile, the manufacturing cost is favorably controlled.
