Description

Transfer chute device for belt conveyor

Technical Field

The invention relates to the technical field of belt conveyors, in particular to a transshipment chute device for a belt conveyor.

Background

The belt conveyor is a device for conveying materials in various industries such as mines, coal, metallurgy, ports, building materials, chemical engineering and the like, and has the characteristics of high production efficiency, low noise, large conveying capacity, low energy consumption, capability of realizing long-distance continuous transportation, simple structure, low operating cost and the like.

Due to terrain limitation and process requirements, a conveyor at one position is often required to transfer materials to a conveyor at another position, and a conveyor at a higher position (referred to as a high conveyor for short) transfers materials to a belt of a conveyor at a lower position (referred to as a low conveyor for short) through a belt and a chute, so that the materials are transferred.

Generally, a chute mother plate of an upper chute of a high conveyor is of a circular cross section, and a wear-resistant lining plate fixed on the chute mother plate is a cambered steel plate. However, the wear-resistant lining plate is difficult to process and manufacture and is not easy to connect with the chute mother plate due to high hardness and high toughness.

Traditionally, a hard connection, such as a flanged connection or a field weld, is used between the upper chute of the high conveyor and the lower chute of the low conveyor. Due to factors such as manufacturing and installation errors, flatness of an installation site, even temporary process change and the like, if a hard connection mode is adopted, the relative installation position of equipment is fixed, the degree of freedom is zero, and any adjustment cannot be carried out. This puts high demands on the manufacturing and processing, and brings great difficulties to the installation, and also does not facilitate the later transfer of the conveyor.

In addition, in the prior art, the connection between the upper chute of the high-rise conveyor and the lower chute of the low-rise conveyor can be sealed by a soft rubber plate to avoid dust raising, but under the condition of adopting fixed connection, if the position of the lower belt conveyor is changed, the soft rubber plate can not be connected with the lower chute.

Accordingly, there is a need in the art for a transfer chute apparatus for a belt conveyor that eliminates or at least alleviates all or some of the above-mentioned deficiencies of the prior art.

Disclosure of Invention

In view of the above-mentioned problems of the prior art, it is an object of the present invention to provide a transfer chute apparatus for a belt conveyor, which can make an upper chute rotate in a lower chute of a low conveyor by making a cylindrical member protruded from the bottom of the upper chute of the high conveyor have a regular polygonal cross section, and can make an outer mother plate of the cylindrical member protruded from the bottom of the upper chute and an inner wear-resistant lining plate thereof be flat steel plates, so as to facilitate the manufacturing and mounting of the outer mother plate and the wear-resistant lining plate, and to simplify the field mounting of the belt conveyor due to factors such as manufacturing accuracy, mounting error, adjustment of field flatness or mounting position, and temporary process change.

The cross section of the cylindrical member protruding from the bottom of the upper chute of the high conveyor may be a regular polygon, preferably with the number of sides n ≧ 6, the larger n, the more nearly circular the cross section. And a wear-resistant lining plate can be fixedly arranged on the inner wall of the outer mother plate of the cylindrical member. For example, the wear-resistant lining plate can be fixed in a bolt connection mode so as to be convenient to disassemble and replace. The cross section of the cylindrical component can adopt a regular polygon instead of a circle, and the cylindrical component has the advantages that the outer mother plate and the wear-resistant lining plate which are fixedly connected can be both flat plates or flat steel plates, so that the cylindrical component is different from the situation that the upper chute in the background technology adopts a circle cross section, and in the latter situation, the corresponding chute mother plate is a cambered surface and is not easy to process and manufacture; the corresponding wear-resistant lining plate is a cambered surface, and the wear-resistant lining plate is high in hardness and toughness, so that the wear-resistant lining plate is not beneficial to processing and is not easy to connect with a chute mother plate.

On the other hand, an L-shaped lower annular connecting frame can be fixed above the lower chute of the low-type conveyor, the second end of the soft rubber plate can be fixed on the third side surface of the lower annular connecting frame by using a fastening piece comprising a bolt, a nut, a washer and the like, and the fastening piece does not need to be detached when the angle of the high-type conveyor and the low-type conveyor is adjusted. The lower annular connecting frame is different from the upper annular connecting frame at the bottom of the upper chute, a plurality of annular grooves can be formed in the planar third side face, close to the soft rubber plate, of the lower annular connecting frame, and the second end of the soft rubber plate can be fastened to the annular grooves. Through like this, when can be convenient for the lower part chute carries out angle modulation along with the conveyer, soft rubber sheet need not dismantle with the removal, only need loosen or move away the fastener from annular slot, wait to adjust to suitable position after, again with the fastener fasten can, consequently made things convenient for the installation and the dismantlement of lower part chute for the upper portion chute. In addition, the sealing device consisting of the upper annular connecting frame, the lower annular connecting frame and the soft rubber plate can prevent dust in the belt conveyor from escaping outwards.

Furthermore, the connection between the upper chute and the lower chute can be sealed by a soft rubber plate, so that environment pollution caused by dust and the like can be avoided.

Furthermore, the upper surface of the soft rubber plate close to the L-shaped lower annular connecting frame of the lower chute is provided with an annular groove, the lower chute can be conveniently subjected to angle adjustment along with the conveyor, the soft rubber plate serving as a sealing device does not need to be detached and moved away from the upper chute, only the threaded connection devices such as fasteners between the soft rubber plate and the lower chute need to be loosened, after the lower chute is adjusted to a proper position, the threaded connection devices are fastened and connected with the soft rubber plate and the lower chute again, and the lower chute is convenient to install and detach relative to the upper chute.
