Description

Technical Field

[0001] The invention belongs to the technical field of scraper, and particularly relates to a scraper automatic chain-on device for a gangue filling scraper conveyor. Background Art

[0002] In a gangue filling working face, a gangue filling scraper conveyor is mainly used for transporting gangue and other filling materials. Therefore, the gangue filling scraper conveyor is an essential main equipment in the filling process. The normal operation of the gangue filling scraper conveyor is the key to ensuring the normal operation of the filling process. At present, due to the requirements of the filling process, all gangue filling scraper conveyors on the market adopt unsealed middle troughs to achieve gangue filling. Since the middle trough has no bottom plate design, during the filling process, as the gangue drops from the dropping hole, large pieces of gangue will get stuck on one side of the scraper, causing uneven loads on the two scraper chains, resulting in the running attitude of the scraper in the lower chain path tilting and slipping out of the lower chain path. If the scraper cannot be reset in time, the scraper will get stuck at the transition trough at the tail of the filling scraper conveyor, leading to poor operation of the gangue filling scraper conveyor, and even safety accidents such as scraper breakage or scraper chain breakage.

[0003] The existing scraper chain-on port is realized by using an elastic plate and a connecting component. Under the action of a guide plate and a spring plate, the scraper that has slipped out of the lower chain path is automatically adjusted back to the lower chain path, and then the spring plate uses its own elastic force to reset. The existing scraper chain-on mechanism of the filling scraper conveyor adopts a spring plate and a guide plate design, which has a short service life and is not easy to replace. During use, the toughness of the spring plate is not easy to control, and phenomena such as breakage or obstruction of the scraper reset will occur. Also, because the chain-on mechanism is at the bottom of the transition trough of the scraper conveyor, it is difficult to replace, and it cannot be replaced and maintained in time. To solve the problem of automatic chain-on of the scraper of the gangue filling scraper conveyor, a scraper automatic chain-on device for a gangue filling scraper conveyor is proposed. Summary of the Invention

[0004] The purpose of the invention is to provide a scraper automatic chain-on device for a gangue filling scraper conveyor, to solve problems such as the existing scraper getting stuck at the transition trough at the tail of the filling scraper conveyor, resulting in poor operation of the gangue filling scraper conveyor, scraper breakage or scraper chain breakage accidents, and thus affecting production efficiency.

[0005] To achieve the above purpose, the invention provides the following technical solutions:

[0006] A scraper automatic chain - loading device for a waste - rock filling scraper conveyor, which includes an inner baffle of the scraper conveyor main body sleeved with a scraper chain. A number of equally - spaced scrapers are sequentially arranged on the scraper chain. A transition chute is arranged below the scraper chain, and the transition chute is welded to the bottom of the left end of the scraper conveyor main body. A shaft - type flipping structure is arranged at the right end of the transition chute. The bottom positions of the shaft - type flipping structure are respectively welded to the two side walls of the inner cavity of the scraper conveyor main body. A small guide rail plate is arranged on the bottom surface of the right end of the transition chute, and the top of the small guide rail plate is welded to the two side walls of the inner cavity of the scraper conveyor main body. The shaft - type flipping structure is mainly composed of a shaft assembly and a flap assembly.

[0007] Further, the shaft assembly is symmetrically welded to the left - hand side wall of the inner cavity of the scraper conveyor main body through two shafts. The two shafts are sleeved and adapted to each other. The upper surface of the flap assembly body is welded with a top plate, and the top plate is located above the left part of the flap. The lower surface of the flap assembly body is welded with two triangular parts, and the two triangular parts are symmetrically welded below the left part. The tail of the flap is welded to the shaft.

[0008] Further, the shaft assembly is symmetrically welded to the right - hand side wall of the inner cavity of the scraper conveyor main body through two shafts.

[0019] The technical solutions of the present invention will be clearly and completely described below through specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0020] As Figure 1 shown, this embodiment provides a scraper automatic chain - feeding device for a gangue - filling scraper conveyor. A baffle 6 inside the scraper conveyor main body 7 is sleeved with a scraper chain 2. A number of equally - spaced scrapers 3 are sequentially arranged on the scraper chain 2. A transition chute 1 is arranged below the scraper chain 2. The left - end bottom of the transition chute 1 and the scraper conveyor main body 7 are welded. A rotating - shaft - type flipping structure 5 is arranged at the right end of the transition chute 1. The bottom of the rotating - shaft - type flipping structure 5 is respectively welded to the two side walls of the inner cavity of the scraper conveyor main body 7. A small guide rail plate 4 is arranged on the bottom surface of the right end of the transition chute 1. The top of the small guide rail plate 4 is welded to the two side walls of the inner cavity of the scraper conveyor main body 7. The rotating - shaft - type flipping structure 5 is mainly composed of a rotating - shaft assembly 8 and a flap assembly 9. The rotating - shaft assembly 8 is symmetrically welded to the left - hand side wall of the inner cavity of the scraper conveyor main body 7 through two rotating shafts. The two rotating shafts are sleeved and adapted to each other. The upper surface of the body of the flap assembly 9 is welded with a top plate, and the top plate is located above the left part of the flap. The lower surface of the body of the flap assembly 9 is welded with two triangular members, and the two triangular members are symmetrically welded below the left part. The tail of the flap is welded to the rotating shaft. The rotating - shaft assembly 8 is symmetrically welded to the right - hand side wall of the inner cavity of the scraper conveyor main body 7 through two rotating shafts. The two rotating shafts are sleeved and adapted to each other. The upper surface of the body of the flap assembly 9 is welded with a top plate, and the top plate is located above the right part of the flap. The lower surface of the body of the flap assembly 9 is welded with two triangular members, and the two triangular members are symmetrically welded below the right part. The tail of the flap is welded to the rotating shaft. A motor is arranged at the right end of the scraper conveyor main body 7.

[0021] In this embodiment, the gangue filling scraper conveyor adopts an independent chain-up structure and a rotating shaft type flipping structure 5. It is designed with mechanisms such as left and right flap assemblies and rotating shaft assemblies. In the figure, it shows the open state of the chain-up mechanism of the gangue filling scraper conveyor (the dotted line is the closed guiding state). When the scraper 3 in the gangue filling scraper conveyor derails, it can be guided by the small guide plate 4 at the front end of the rotating shaft assembly, so that the scraper 3 runs to the rotating shaft of the rotating shaft assembly. The two scraper chains 2 are in a tensioned state. By relying on the tension of the two scraper chains 2, the left and right flap assemblies are opened, enabling the scraper 3 to return to the lower chain path to achieve chain-up. The running and chain-up route of the scraper 3 is shown in the scraper running track in the figure. This device is composed of a rotating shaft assembly, a left flap assembly, a right flap assembly, and a small guide plate. By combining the lower wing plate with the flap assembly, it can be independently flipped under the influence of the scraper running direction for scraper chain-up, making full use of space, being small in size, high in strength, simple in processing, convenient to replace, and requiring no manual operation.
