2results about How to "Eliminate tedious work" patented technology

This utility model belongs to the technical field of fertilization equipment, specifically a lily planting fertilization device, including a frame. A pesticide delivery assembly is installed on the top of the frame, and a delivery pipe is installed at the delivery end of the assembly. The delivery pipe is fixedly connected to the frame. A second motor is fixedly connected to the middle section of the bottom of the frame. A spraying assembly is installed outside the second motor, and evenly distributed nozzles are installed at the spraying end of the spraying assembly. Travel wheels are rotatably connected to both sides of the frame. This utility model provides a lily planting fertilization device that uses a second motor to drive a transmission frame and transmission pipe to rotate the distribution pipe and nozzles at a uniform speed. During this uniform rotation, the nozzles can cover a wider area and evenly distribute fertilizer, ensuring that each part of the lily receives the same nutrition. The entire spraying process can be automated, eliminating the tedious work of manually adjusting the spray angle.

This invention discloses a bag-hanging device and method for flexible concrete mold hanging bags after filling a coal mining frame. The device includes a pneumatic winch and a limiting frame. The pneumatic winch is connected to the limiting frame via a lifting control wire rope, and the limiting frame is connected to a hanging frame via the same wire rope. The hanging frame includes a bag-hanging mechanism, which is equipped with a bag-releasing and shifting mechanism and a bag-unfolding and hanging mechanism, which do not contact each other. The bag-hanging method proposed in this invention allows the flexible mold hanging bags to stand upright by being filled with air columns from the flexible mold frame, eliminating the need for hoisting operations. Simultaneously, its supporting devices and deployment method move the bags towards the goaf by their own weight and rolling motion. Combined with the straightening and shaping operations of related devices, construction personnel do not need to work in the goaf, reducing labor consumption and improving work efficiency and safety.
