Description

Technical Field

[0001] The present application relates to the technical field of slag scraping devices for mining, and in particular to a mechanical slag scraping arm for a mining conveyor. Background Art

[0002] In the process of narrow tunnel construction, in order to facilitate the continued construction and excavation, it is usually necessary to use a mining conveyor to transport the waste slag out of the tunnel. A mining conveyor is a conveyor that uses a scraper chain to transport bulk materials in a trough.

[0003] At present, the general mining conveyor includes a slag scraper arm and a conveyor. The slag scraper arm is rotatably connected to the conveyor, and the end of the slag scraper arm away from the conveyor is rotatably connected to the bucket. When in use, the slag scraper arm is extended forward to the slag position, and the slag scraper arm groove is pressed down by the hydraulic cylinder to make the shovel hook the slag stone. The slag scraper arm returns, and the shovel moves inward to scrape the slag stone into the conveyor bucket, and then it is transported along the belt and the belt transport frame, thereby completing the transportation of waste slag.

[0004] However, during the slag removal process, stones in the slag are easily stuck between the teeth of the bucket, making it difficult for the bucket to penetrate into the slag, thereby reducing the slag cleaning efficiency of the mining conveyor. Summary of the invention

[0005] In order to improve the cleaning efficiency of waste slag by a mining conveyor, the present application provides a mechanical slag scraper arm for a mining conveyor.

[0006] The present application provides a mining conveyor mechanical slag removal arm, which adopts the following technical solution: A mining conveyor mechanical slag arm, comprising a slag arm, a bucket, an elastic block and a first adjustment component, wherein the bucket is rotatably connected to the slag arm, the bucket is provided with a plurality of shovel teeth, the plurality of shovel teeth are arranged along the length direction of the bucket bottom, and the shovel teeth are connected to the opening side of the bucket; the elastic block is hollow inside and fixedly connected to the bucket, the elastic block is located at the connection between the bucket and the slag arm, and is located on the side of the slag arm close to the bucket opening; the first adjustment component comprises a first driving part and a first adjustment part, both of which are arranged on the bucket, and the first driving part is used to drive the first adjustment part to clean stones between the shovel teeth; The first driving part includes a first telescopic rod and a first adjusting rod. The bucket is hollow inside. The first telescopic rod is fixedly connected in the bucket. The rod cavity of the first telescopic rod is communicated with the elastic block. The first adjusting rod is rotatably connected in the bucket, and one end of the first adjusting rod is slidably connected with the movable end of the first telescopic rod. The rotation point of the first adjusting rod is located at an end of the first adjusting rod away from the movable end of the first telescopic rod. The first adjustment part is provided with multiple groups, and the multiple groups of the first adjustment parts are arranged along the length direction of the bucket bottom; the first adjustment part includes a sleeve and a push rod, the sleeve is fixedly connected in the bucket and is located on the side of the bucket close to the shovel teeth; the push rod is inserted into the bucket and slidably connected in the sleeve, the sliding direction of the push rod is the width direction of the bucket bottom, one end of the push rod is fixedly connected to the first adjustment rod, and the other end is fixedly connected to a push block, the push block is located between adjacent shovel teeth and located on the outside of the bucket.

[0007] By adopting the above technical solution, after the bucket scoops up the waste slag, the slag scraping arm drives the bucket to rotate, the slag scraping arm squeezes the elastic block, the elastic block provides power for the first driving part, and the first driving part drives the first adjusting part to clean the stones between the adjacent shovel teeth, so that the slag scraping arm can easily clean the stones stuck between the shovel teeth, so that the shovel teeth can be easily inserted into the waste slag, and thus it is easy to improve the cleaning efficiency of the waste slag; Specifically, when a stone is stuck between the shovel teeth, the slag scraper arm drives the bucket to rotate, and the slag scraper arm squeezes the elastic block. Since the rod cavity of the first telescopic rod is connected to the elastic block, the volume inside the elastic block decreases, and the volume of the rod cavity of the first telescopic rod increases. The movable end of the first telescopic rod moves, and the movable end of the first telescopic rod drives one end of the first adjusting rod to rotate. Under the action of the lever principle, the thrust of the other end of the first adjusting rod increases, and the power is transmitted to the first adjusting part, so that the first adjusting part can easily clean the stone stuck between the shovel teeth, so that the shovel teeth can be easily inserted into the waste slag, and then it is easy to improve the cleaning efficiency of the waste slag. The movable end of the first telescopic rod drives one end of the first adjusting rod to rotate. Under the effect of the lever principle, the thrust of the first adjusting rod away from one end of the first telescopic rod increases, and drives the push rod to move. The push rod slides toward the outside of the bucket along the axial direction of the casing, and the push rod drives the push block to move. The push block is squeezed with the stone.

[0009] By adopting the above technical solution, when a stone is stuck between the shovel teeth, the top rod cannot push the stone, so that the stroke of the top rod is reduced. Under the connection action of the first adjusting rod, the stroke of the movable end of the first telescopic rod is also reduced. Compared with the state of the rod cavity of the first telescopic rod when the top rod can push the stone, the volume of the rod cavity of the first telescopic rod is reduced. Since the rod cavity of the first telescopic rod is connected to the elastic block, the volume inside the elastic block is also reduced. The slag scraper arm continuously squeezes the elastic block, the movable end of the first telescopic rod cannot move, the internal volume of the elastic block decreases accordingly, the elastic block transmits power to the second driving part, the second driving part provides power to the second driven part, the second driven part drives the second adjusting part to drive the shovel teeth to rotate, so that the stuck stones are easy to fall from between the shovel teeth, thereby making it easy to improve the cleaning efficiency of the waste slag.

[0011] By adopting the above technical solution, the slag scraper arm continuously squeezes the elastic block. Since the liquid storage box is connected with the rod cavity of the first telescopic rod through the guide tube, the overflow valve is opened under the action of pressure, and the volume in the elastic block continues to decrease. The liquid storage box transmits power to the second driven part, and the second driven part drives the second adjusting part to drive the shovel teeth to rotate, so that the stuck stones are easy to fall from between the shovel teeth, thereby making it easy to improve the cleaning efficiency of the waste slag.
