Opening and closing device of feed inlet of garbage container

Abstract

The invention discloses an opening and closing device of a feed inlet of a garbage container in the technical field of environmental sanitation. The opening and closing device comprises a feed inlet frame and also comprises an opening and closing door for opening and closing the feed inlet. The opening and closing device also comprises a rotary driving mechanism capable of controlling rotary opening and closing motions of the opening and closing door; the opening and closing door is arranged of a foldable door-shaped structure and the rotary driving mechanism is in transmission connection to a main door plate. The opening and closing device also comprises a linking mechanism, two ends of which are separately connected to the main door plate and an auxiliary door plate; the opening and closing device also comprises a movable ejector rod which is rotatably mounted on the feed inlet frame, the free end of which leans against the linking mechanism to drive the whole opening and closing door to expand; a guide pin is fixed on the side edge of the main door plate, a guide slide hole is formed in the movable ejector rod, and the guide pin is movably threaded in the guide slide hole. The rotary opening and closing motions of the opening and closing door are assisted by means of parts such as the movable ejector rod and the linking mechanism, so that the feed inlet of the opening and closing door is conveniently opened and closed.

Description

technical field [0001] The invention relates to the technical field of sanitation, in particular to an opening and closing device for a garbage container feed opening. Background technique [0002] At present, the opening and closing device of the feeding port of the garbage container includes the feeding port frame arranged around the feeding port and fixed on the box body, the opening and closing door for opening and closing the feeding port, and the controllable opening and closing device. The rotary drive mechanism for door rotary opening and closing. When closing the feed port, the rotary drive mechanism outputs power to drive the opening and closing door to rotate to stick to the frame of the feed port and seal the feed port. Since the opening and closing doors are usually heavy, the workload of the rotary drive mechanism is very large. The resulting problem is that the damage rate and failure rate of the rotary drive mechanism are very high. If it is too large, it w...

AI Technical Summary

Problems solved by technology

Due to the heavy weight of the opening and closing door, the workload of the rotary drive mechanism is very large. The resulting problem is that the damage rate and failure rate of the rotary drive mechanism are very high. Large, it often leads to the situation that the opening and closing of the door is not tight
