Description

Technical Field

[0001] The utility model belongs to the technical field of bulk material storage bin discharging equipment, and in particular relates to a flap type steel grille device for bulk material storage bin discharging. Background Art

[0002] At present, most of the pit steel grilles in the bulk material warehouse outbound system use ordinary steel grilles, which do not have an active closing function. In practice, after the material enters the warehouse, it will pass through the steel grille into the lower hopper, filling the lower hopper with materials. For materials that are easy to compact, if the storage time is too long, the material is easy to compact into blocks in the lower hopper and cause blockage, which will not achieve the expected outbound output, reduce the outbound efficiency, and increase the operating costs of the enterprise. Considering the above factors, it is necessary to design a steel grille device with active opening and closing functions. Summary of the invention

[0003] Purpose of the utility model: The purpose of the utility model is to address the deficiencies of the prior art and to provide a flap-type steel grating device for bulk material storage outlets, so as to prevent the accumulation and compaction of materials in the lower hopper, which affects the efficiency of outlets.

[0004] Technical solution: The utility model describes a flap-type steel grating device for bulk material storage outlet, comprising a driving device, a long connecting rod, a flap connecting rod, a lower top rod, a rotating shaft, an upper flap and a steel grating; a long hole is provided on the side of the upper flap, the rotating shaft is connected to the upper flap through the long hole, the upper flap is installed in the notch on the transverse grating of the steel grating, and the steel grating is inserted into the longitudinal grating after the upper flap and the rotating shaft are installed, and the driving device is installed on both sides above the lower hopper of the bulk material storage by embedded bolts. The upper flap is connected to the ground through a crank-connecting rod mechanism formed by a long connecting rod, a flap connecting rod, a lower push rod and a rotating shaft. When the driving device is working, the push rod is extended and retracted to drive the long connecting rod to do reciprocating motion, so that the upper flap is flipped 90 degrees, thereby realizing the active opening and closing function of the steel grille.

[0005] Furthermore, as a preferred embodiment, a mounting plate with a long hole is welded to the side of the upper flap, and the rotating shaft is inserted into the long hole.

[0006] Furthermore, as a preferred embodiment, a pair of cranks are installed at both ends of the rotating shaft.

[0007] Furthermore, in order to prevent the material's own gravity from pressing the upper flap downward, the crank of the rotating shaft is in a vertical position when the upper flap is closed.

[0008] Furthermore, in order to facilitate maintenance, a detachable cover is provided above the driving device.

[0009] Beneficial effects: The device of the utility model is designed to address the defect that the grille of the bulk material storage system in the prior art does not have the function of automatic closing. Through the design of this solution, the automatic opening and closing of the flap grille can be realized to prevent the accumulation and compaction of materials in the lower hopper, which affects the efficiency of the storage. In addition, when the upper flap in the new structure is closed, the crank of the rotating shaft is in a vertical position, which can effectively prevent the material's own gravity from pressing the upper flap downward. A detachable cover plate is provided above the drive device for easy maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element, or there may also be a central element; when an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time; the terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.
