Description

Technical Field

[0001] The utility model belongs to the technical field of scraper conveyors, and more specifically, particularly relates to a highly wear-resistant heavy-duty scraper conveyor. Background Art

[0002] Scraper conveyors are conveyors that use scraper chains to transport bulk materials in the trough. Scraper conveyors whose adjacent middle troughs can bend to a limited extent in the horizontal and vertical planes are called flexible scraper conveyors. Among them, the working face conveyor with a 90-degree bend at the intersection of the working face and the transport tunnel is called a "corner scraper conveyor". In the current coal mining working face, the role of the scraper conveyor is not only to transport coal and materials, but also to serve as the running track of the coal mining machine. Therefore, it has become an indispensable main equipment in the modern coal mining process.

[0003] Based on the above, the inventors have found the following problems: scraper conveyors usually use chains for power transmission to pull the scraper to move, but the chain will become loose when used for a long time, causing the chain to stretch. The scraper on the chain will sag due to gravity, and the lower part of the scraper will fit onto the material plate. The scraper will produce greater friction with the material plate during movement, causing abnormal noise and wear that will reduce the overall service life.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a highly wear-resistant heavy-duty scraper conveyor is provided, in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a highly wear-resistant heavy-duty scraper conveyor to solve the problem that the current chain will become loose after long-term use, causing the chain to stretch, and the scraper on the chain will sag due to gravity, and the lower part of the scraper will fit onto the material plate and cause wear.

[0006] The purpose and effect of the highly wear-resistant heavy-duty scraper conveyor of the utility model are achieved by the following specific technical means:

[0008] Furthermore, a movable groove is opened on the side surface of the side plate, the diameter of the connecting shaft is matched with the width of the movable groove, and both ends of the connecting shaft pass through the movable groove and are movably plugged into the interior of the plug-in tube.

[0009] Furthermore, the number of the rotating shafts and lifting blocks is four, the four lifting blocks are respectively located at the two ends of the two connecting shafts, and connecting clamp wheels are installed at the lower parts of the four rotating shafts, and the four connecting clamp wheels are connected through toothed belt transmission.

[0010] Furthermore, a first driving motor is installed at the lower part of one of the rotating shafts, an output end of the first driving motor is connected to the rotating shaft, and the first driving motor is connected to a fixed plate.

[0011] Furthermore, a scraper is arranged on the chain, a second drive motor is arranged on the transmission sprocket, an output end of the second drive motor is connected to the transmission sprocket, and the second drive motor is connected to the side plate.

[0012] Furthermore, a support leg is installed at the lower part of the fixing plate, and the lower end of the support leg is flush with the lower end of the supporting leg.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model discloses a connecting clamp wheel drives a plurality of connecting clamp wheels to rotate synchronously through a toothed belt. At this time, a plurality of rotating shafts rotate synchronously. When the rotating shaft rotates, the lifting block can be driven to rise through a thread. When the lifting block rises, the plug-in cylinder can be driven to move upward synchronously. The connecting shaft can be driven to move upward through the plug-in cylinder. The connecting shaft drives the adjusting sprocket to rise.
