Abstract: A weeding device for crops having a seedling avoidance function includes a rack connected to a weeding machine. A hydraulic pump and two hydraulic cylinders are mounted to the rack. Bottom ends of each of the two hydraulic cylinders are provided with a vertically arranged support rod. An inter-row weeder is mounted to a bottom end of each of the two support rods. A slider configured to reciprocate in a horizontal direction is positioned on two slide rails that are mounted to the rack. An inter-plant weeder is mounted to a bottom side of the slider. A plurality of weeder blades are arranged side by side on the inter-plant weeder. At the weeding position, an arrangement direction of weeder blades is perpendicular to an advancing direction, and at the weed avoidance position, the arrangement direction of the weeder blades is parallel to the advancing direction, thereby avoiding crops.

Abstract: An automatic packing machine and automatic packing method for express delivery are provided. The automatic packing machine for express delivery includes: a frame; a box discharging mechanism, fixed to the frame; a weighing mechanism, fixed to the frame, the weighing mechanism including a weighing plate and a weighing plate steering engine which are arranged in coordination and an image collecting module, the weighing plate steering engine and the image collecting module being fixed to the frame, and the image collecting module facing the weighing plate; a box body unfolding mechanism; a box closing mechanism; a conveying mechanism; and a controller, connected to all other structures of the automatic packing machine for express delivery. Through the technical solutions of the present invention, multiple functions are integrated, the degree of automation is high, and different items are packaged by using different box bodies.
