The utility model discloses a kind of goods classification devices, specifically related to goods classification equipment technical field.It includes main conveying mechanism, several pusher mechanisms, several secondary conveying mechanisms, the main conveying mechanism includes first mounting bracket, the inside of first mounting bracket is provided with several conveying rollers, the top of first mounting bracket is fixedly installed with detection module, several pusher mechanisms are arranged between the gap of several conveying rollers, the secondary conveying mechanism is arranged at the side of pusher mechanism, and the number of pusher mechanism and secondary conveying mechanism is consistent.The utility model discloses when retracting after push plate completes goods push, if subsequent goods have entered classification area by transmission belt, flat retraction path can collide with subsequent goods, resulting in the defect that goods are stacked or damaged, and a kind of goods classification device is proposed, the push plate only protrudes the top of main conveying mechanism in pusher process, and push plate will shrink to the bottom of main conveying mechanism after pusher is completed.

The application provides a manhole at a connection of a drainage pipeline, and belongs to the technical field of manholes. The manhole comprises a drainage unit and a cleaning unit. The drainage unit comprises a manhole body and two groups of connection assemblies connected to the manhole body. The cleaning unit is arranged in the manhole body. The cleaning unit comprises a filter cylinder arranged at a lower part of the manhole body, a lifting assembly connected to the filter cylinder, and a cleaning assembly arranged in the filter cylinder. The lifting assembly is used to drive the filter cylinder to lift. One end of the filter cylinder corresponds to one group of the connection assemblies, and the other end of the filter cylinder corresponds to the other group of the connection assemblies. A taking and placing opening is arranged at a top of the filter cylinder. The cleaning assembly is used to clean adhering matters on an inner wall of the filter cylinder. The manhole at the connection of the drainage pipeline is used to solve the problems of safety hazards, easy formation of secondary blockage, and high cleaning cost in the existing manhole desilting.
