The invention discloses a planting and soil covering device for a plant seedling planting groove. The planting and soil covering device mainly comprises a lifting module, a seedling planting module and a soil covering module. The lifting module comprises a lead screw module, a planting and soil covering mechanism mounting plate, a servo motor, a synchronous belt, a synchronous wheel and the like; the seedling planting module comprises a duckbilled planting device, a plurality of groups of duckbilled opening and closing long rods, an opening and closing long rod mounting plate, a planting mechanism L mounting plate, a mounting plate, a duckbilled mounting plate fixing block, a telescopic cylinder, a linear guide rail mounting block, a linear guide rail, a duckbilled opening and closing pull rod, a duckbilled opening and closing special-shaped connecting block, a duckbilled planting device mounting frame, a single-side duckbilled planting device and the like; the soil covering module comprises a soil covering plate opening and closing mechanism, a soil covering plate, a telescopic cylinder, a polished shaft, an upper mounting plate, a vertical mounting plate, a linear bearing, a polished shaft seat mounting block, a lower mounting plate, a soil covering plate mounting block, a connecting rod, a linear guide rail, a middle mounting plate, a polished shaft seat, a cylinder mounting block and the like. The invention designs the planting and soil covering device suitable for the planting mode of the plant seedling planting groove, the action is simple and reliable, and the two actions of planting and soil covering can be completed through one-time lifting action. In addition, according to the seedling planting and soil covering method adopted by the invention, all actions are clear in movement rule, and the operation reliability of the device is further improved.

This application discloses an automatic fixing and locking device and its working method for transporting target projectiles. The automatic fixing and locking device includes: a rotary motor, a locking and fixing mechanism, and a power transmission device. The rotary motor is mounted on the erecting support of the launching device. The locking and fixing mechanism is mounted on the erecting support of the launching device and is rotatably connected to the erecting support. The locking and fixing mechanism includes at least: a cylinder mounting plate, a fixing plate, a cylinder, a cylinder connecting plate, a first opening and closing action plate, a first contact limiting plate, a second opening and closing action plate, a second contact limiting plate, a first transmission connecting plate, a second transmission connecting plate, and a power transmission wheel. The power transmission wheel is disposed on the fixing plate and is connected to the rotary motor through the power transmission device. This application has a high degree of automation, requiring no manual intervention; automatic locking and unlocking of the target projectile placed on the launching device can be achieved through remote control.
