A feed door device for a tank-type food waste container dedicated to a vertical station

Abstract

The invention discloses a feeding door device of vertical station special tank type food waste container, which belongs to the technology field of environmental sanitation. The feeding door device of vertical station special tank type food waste container, which belongs to the technology field of environmental sanitation, comprises an oscillating cylinder, a cylinder support, a feeding opening cover, a lock frame, a hook lock assembly and a connecting drive assembly used for connection with the feeding opening cover and the end of the oscillating cylinder. The hook lock assembly comprises a guide rail, an outer support, a lock plate, a straight rack and a locking cylinder. An arc rack with outward meshing is arranged on the edge of the lock plate. A hook extending outward is arranged on the edge of the lock plate. The hook and the arc rack are staggered. A lock rod is arranged on the lock frame; the arc rack on the edge of the lock plate engages with the straight rack. When the feeding opening cover covers the waste container, The straight rack moves in a straight line under the drive of the locking cylinder, so the straight rack drives the lock plate to rotate and makes the hook hook the lock rod. The feeding door device of vertical station special tank type food waste container is characterized by a strong locking force and a shock resistant.

Description

technical field [0001] The invention relates to the technical field of sanitation, in particular to a feed door of a tank-type food waste container. Background technique [0002] A Chinese patent is disclosed in the prior art, the patent number is 2013201147466, and the name is the feed port mechanism of the tank type food waste container, which includes a steel ring for connecting pipes, a circular feed port cover, and a locking mechanism; The cover is fixed with an optical axis, which penetrates into the bushing of the steel ring of the connecting pipe so that the cover of the feeding port is hinged on the steel ring of the connecting pipe, and the swing oil cylinder is used to drive the optical axis to rotate; the locking mechanism includes a A locking oil cylinder on the steel ring, a wedge-shaped head at the front end of the piston rod, and a fork that is fixed on the feed inlet cover and has a locking hole at the lower end. In use, the garbage can is placed vertically...

Problems solved by technology

[0003] However, in engineering practice, such a locking method is still irrelevant, and the piston rod of the locking cylinder will be directly vibrated. The direction of such vibration deflection is often perpendicular to the piston rod of the locking cylinder, which can easily cause the locking cylinder itself The service life is reduced, it is easy to be damaged, and it relies on the wedge block for locking, the locking force is limited, and it is easy to wear the wedge block
