The utility model discloses a kind of seed metering device with arc flow guide plate, it is related to agricultural production equipment technical field.Seed metering device includes front shell, arc flow guide plate, seed metering disc, rear shell and connecting shaft, arc flow guide plate, seed metering disc and rear shell are sequentially connected by connecting shaft, arc flow guide plate includes fixed seat, arc flow guide rod and circular flow guide piece, one end of arc flow guide rod is connected with fixed seat, the other end of arc flow guide rod is connected with circular flow guide piece;Seed metering disc is provided with several evenly distributed composite holes.In the utility model, when arc flow guide plate rotates, it exerts certain circumferential thrust and radial pressure on inner layer population, and is transmitted to outer layer population from inside to outside, so that the population of entire filling seed area moves violently, thereby increasing the filling force and relative movement speed of the seed to be filled above composite hole.The arc flow guide plate of the utility model can effectively avoid seed damage compared with existing straight line flow guide plate, and effectively improve filling effect under high-speed operation.

The application relates to the technical field of cross-domain multi-modal robots, in particular to a land-air robot with high ground self-adaptability and a control method thereof. The land-air robot comprises an air movement unit, a ground movement unit and an automatic driving module. The air movement unit is used for providing flight power for the land-air robot, so that the land-air robot has a flight mode. The ground movement unit is arranged at the bottom of the air movement unit, so that the land-air robot has a ground movement mode. The ground movement unit comprises a movement module and a five-link wheel-foot mechanism symmetrically arranged on the left and right sides of the land-air robot. The movement module is used for adjusting the posture of the five-link wheel-foot mechanism, so that the land-air robot realizes dynamic balance and posture righting in the ground movement mode. The automatic driving module is electrically connected with the air movement unit and the ground movement unit. The land-air robot in the application can move on land and in the air, and has good trajectory tracking performance in the land-air dual mode.

This utility model relates to a universal chassis, including a chassis body, a base plate, and an outer shell on top of the base plate. An inner frame is located inside the outer shell, with casters at the four corners of the bottom of the inner frame. Two mounting plates extend downwards from the center of the inner frame, with drive wheels mounted on the mounting plates via drive components. A slot is provided on the rear side of the outer shell, housing a battery module. Two charging contacts are located on the rear side of the battery module. A depth camera is located on the front top of the outer shell, and two lidar sensors are located diagonally on the top of the outer shell. A lifting slot is located on the rear side of the battery module, with a rotating pull ring within it. The angle difference between the depth camera and the outer shell is 45°. The lidar sensors in this utility model are divided into forward and backward types. The backward lidar is specifically designed for rapidly approaching moving obstacles (such as pedestrians and vehicles) to perform velocity vector analysis. Combined with forward lidar data, collision time can be predicted, supporting robots to perform reversing avoidance or path replanning, making the chassis safer and more flexible in dynamic environments, with a detection range covering 360°.

The application discloses a meal delivery cabinet, method and storage medium, which is used for automatically providing corresponding meal products to a meal serving port according to needs, and comprises a plurality of conveying channels arranged in a cabinet body and used for conveying meal products, and a transfer tray used for receiving the meal products conveyed from the conveying channels, and further comprises a conveying device used for conveying the transfer tray between the conveying channels and the meal serving port, the transfer tray is provided with a blocking body opposite to the conveying channels and a distance detection device used for detecting the distance between the blocking body and the meal products on the transfer tray. The sensor is arranged on the conveying device, different conveying speed change processes are adopted according to the position state of the meal products on the conveying device, so that better conveying speed and stability are obtained.

This application relates to the field of medical device technology, and in particular to a pulse ablation clamping device, including a handle, a support tube, a first ablation clamp, a second ablation clamp, a flexible transmission assembly, and a drive assembly. One end of the support tube is fixedly mounted on the handle, and its interior communicates with the interior of the handle. The first ablation clamp is fixedly mounted on the end of the support tube away from the handle. The second ablation clamp is movable toward or away from the first ablation clamp on the end of the support tube away from the handle. Compared to existing pulse ablation clamping devices, the support tube can undergo plastic deformation, allowing the first and second ablation clamps to move synchronously and rotate synchronously at multiple angles more flexibly, adapting to the tissue orientation of different sites and improving surgical flexibility. The drive assembly can drive the second ablation clamp toward the first ablation clamp via the flexible transmission assembly. Compared to rigid transmission methods, it can transmit power in a non-linear transmission path.
