This utility model discloses a grain storage container equipped with a novel grain discharging device. The container includes a grain storage container with a grain discharging port on each of its two opposite side walls. A bidirectional grain pushing mechanism is provided between the two grain discharging ports inside the container. The bidirectional grain pushing mechanism includes a bidirectional drive assembly, a sprocket assembly, and multiple pusher plate assemblies arranged on the sprocket assembly. The bidirectional drive assembly drives the sprocket assembly to move the multiple pusher plate assemblies in both directions to push grain out from either discharging port. This utility model has the advantages of simple and compact structure, high degree of intelligence and automation, safe and reliable unloading, high unloading efficiency, and strong operational adaptability.

The utility model belongs to the field of electric power overhaul auxiliary equipment, and particularly relates to auxiliary equipment for installing a current transformer. Comprising a placing platform used for placing a current transformer; the placement platform is located on the horizontal centering mechanism, and a transverse movement module and a longitudinal movement module on the horizontal plane are arranged on the centering mechanism; the lifting mechanism is located below the alignment centering mechanism; the current transformer is placed on the placing platform, and rapid installation can be carried out after connecting holes in the upper side and the lower side of the current transformer and installation holes in an installation plate in a switch cabinet are centered through the lifting mechanism and the horizontal centering mechanism. And the placing platform, the horizontal centering mechanism and the lifting mechanism are carried on the walking mechanism. And the traveling mechanism can complete the required transfer in the mounting process.

The invention discloses an emergency protection device for a dehydrator screw conveyor, which is different from the situation that an emergency stop button is correspondingly arranged beside the screw conveyor at present, and an operation area capable of carrying out emergency stop control is small, and is connected with a trigger switch through a rope, so that the operable area of the trigger switch is effectively expanded; the rope is arranged to extend in the length direction of the spiral conveyor, the positions close to the spiral conveyor are all located in the operable area, the rope is higher than the spiral conveyor through the support, workers can conveniently pull the rope with hands to trigger the trigger switch, and therefore in the normal production and maintenance process of the spiral conveyor, the safety of the workers is improved. When foreign matters, clothes corners and even limbs of a worker are wound into the spiral conveyor due to misoperation of the worker, the worker can trigger the trigger switch by pulling the rope at any position near the spiral conveyor, so that the spiral conveyor is stopped in time, the severity of a safety event is prevented from being aggravated, and the safety of the worker is ensured. The sludge treatment stability and safety are favorably improved.
