Fully-sealed discharge door of intermediate storage bin

Abstract

The invention discloses a fully-sealed discharge door of an intermediate storage bin, and belongs to discharge doors. The discharge door structurally comprises a shield, a material port, an arc material door and an arc material door switch driving device, wherein the material port and the arc material door are respectively formed in the shield; openings are formed in the upper end and the lower end of the shield; the upper end of the shield is connected with the intermediate storage bin; the lower end of the shield is connected with a feed port of an agitator; the arc material door comprises an arc plate and end plates arranged on the front side and the rear side of the material port; the arc plate is arranged at the lower part of the material port; the two sides of the arc plate are connected with the lower parts of the end plates; and the arc material door switch driving device is connected with the end plates. Compared with the prior art, the fully-sealed discharge door of the intermediate storage bin has the characteristics that the fully-sealed discharge door solves the problems that material spreading and leaking is caused due to the fact that an existing discharge door cannot be closed tightly, the existing discharge door can be opened automatically due to the gravity of the feeding material if an air cylinder breaks down, repeated feeding happens and the like, so that the fully-sealed discharge door has good popularization and application values.

Description

technical field [0001] The invention relates to a discharge door, in particular to a fully sealed intermediate storage bin discharge door. Background technique [0002] The intermediate storage silo is the intermediate aggregate storage hopper, which is an important part of the mixing plant. The measured aggregate is transported up by the inclined belt conveyor and temporarily stored in the intermediate aggregate storage hopper. After the door of the main mixer is confirmed to be closed, the door of the transition hopper is opened, and the aggregate enters the main mixer for the next concrete production. The intermediate aggregate storage hopper can ensure the uninterrupted production of the equipment and improve the production efficiency of the whole machine. The discharge door is an important part of the storage bin, and its performance determines the quality of the discharge. The discharge door of the old structure is composed of two door panels, the door panels are ins...

Problems solved by technology

[0003] The technical task of the present invention is to provide a fully-sealed intermediate storage bin discharge door for the above-mentioned deficiencies in the prior art. And if the cylinder fails, the discharge door will automatically open due to the gravity of the upper fabric, and there will be problems such as repeated feeding
