The self-unloading two body granary comprises a two body storage and a grain unloading device, wherein the two body storage is provided with a first storage and a second storage, two ventilation heat exchange systems are respectively arranged in the first storage and the second storage, the grain unloading device comprises a box with a first grain unloading cavity and a second grain unloading cavity, a first conveyor used for unloading grains stored in the first grain unloading cavity, a second conveyor used for unloading grains stored in the second grain unloading cavity and a driving device used for driving the first conveyor and the second conveyor to rotate, the first conveyor comprises a first rotation shaft, a first spiral plate and a first driven gear, the second conveyor comprises a second rotation shaft, a second spiral plate and second driven gear, and the driving device comprises a drive motor and a clutch linkage device, and the clutch linkage device comprises a frame body, a transmission shaft, a clutch transmission gear, a belt pulley and a translation limiting piece. The self-unloading two body granary is compact and reasonable in structure.

The invention discloses a multifunctional insulating boot with an alarm device, which includes a control chip, a potential sensor, an alarm device, a pressure generator, a warning light, a support plate, an insole, a boot shaft, a switch, a ventilation device, a fixing piece, a communication Tubes, through holes, ventilation holes, wear-resistant layers, support blocks, communication holes, warning devices, batteries and boot soles; when there is voltage on the surrounding ground, the potential sensor transmits the signal to the control chip for processing, and then the control chip passes the alarm The device energizes the warning light and the warning device to give a warning. The warning light here is an LED waterproof flexible light strip, which is very convenient to give a light alarm to the surroundings. After the warning device is powered on, the push rod on the left side of the electromagnet will first be extended to push the movable block. The connecting seat moves to the left, and then through the connecting rod 1 and the connecting rod 2, the movable seat drives the warning head 1 and the warning head 2 to move up to contact with the soles of the feet. When the staff walks, they will obviously feel the discomfort of the feet, thus ensuring that the staff Can detect danger in time.
