Automatic ascending and descending tail sealing device

Abstract

The invention discloses an automatic ascending and descending tail sealing device comprising a connection board. The back face of the connection board is connected with the tail of a guide groove; thefront face of the connection board is provided with two parallel moving slide rails; a push rod bracket is arranged on the connection board and connected with an electric push rod; a sealing box is connected with the lower portion of the electric push rod; slide block connection bases are arranged on two sides of the sealing box; slide blocks are arranged inside the slide block connection bases and can vertically move along corresponding moving slide rails; and the bottom of the sealing box is sequentially connected with a front sealing board, a middle sealing board and a rear sealing board from front to back. The bottom of the sealing box is of a multi-layer sealing design to seal the guide groove, the material pouring and powder spraying phenomena on a working site are avoided, at the same time, when a bidirectional belt reversely works or scattered materials at the tail of the belt need to be cleaned away, the electric push rod pushes the sealing box to vertically move on the connection board, and the sealing box can ascend or descend.

Description

technical field [0001] The invention relates to the technical field of belt conveyor transfer, in particular to an automatic lifting tail sealing device for a bulk material conveying system. Background technique [0002] Belt conveyor is a commonly used material conveying equipment. It can be widely used in metallurgy, coal, transportation, electric power, building materials, chemical industry, light industry, grain and machinery industries. It is an important tool for conveying coal in electric power enterprises. Transportation Equipment.

Problems solved by technology

[0003] For the bulk material transfer point, due to the height difference at the transfer point, the potential energy of the material is continuously converted into kinetic energy during the falling process of the material in the chute. It is unavoidable to generate dust and powder spraying at the tail, especially in the case of inclination, the material will be dumped under the influence of induced wind and speed, and it must be cleaned manually frequently. The rear part of the traditional material guide trough is only designed with a rear baffle because it cannot be lifted. , leading to spraying, and the material that is poured out cannot be shoveled directly to the belt, and needs to be transferred to other places, increasing maintenance costs

At the same time, when encountering a belt running in both directions, when the material is reversed, the tail seal needs to be lifted, otherwise the material cannot pass through. At present, there is also a part of the lifting sealing device, which is mainly blocked by the rubber plate. When the material is discharged or the induced wind is strong In some cases, it cannot be completely sealed. At the same time, most of them are manually operated. Because the sealing device is set above the belt, the operation is cumbersome and there are potential safety hazards.
