Problems solved by technology
[0003] When using the conveying mechanism to transport mine stones, etc., due to the heavy weight of the stones, the impact force on the roller during the transportation of the stones is relatively large, and the impact frequency is high. Generally, the spring is set at the bottom of the roller Realize the shock absorption function, but the high-frequency impact results in a short service life of the spring, and the replacement of the spring is troublesome and inconvenient to operate

[0033] Specific implementation method: Use the idler 20 to assist the conveyor belt of the conveying mechanism. During the movement of the mine stones on the conveyor belt, there are relatively frequent and large impacts on the idler 20. The idler 20 When it is impacted, it moves downward, which drives the movable bottom plate 3 and the movable block 8 to move downward, and the movable block 8 moves downward to pull the pull rope 11, thereby driving the counterweight ball 12 to move upward, and the gravity of the counterweight ball 12 is used to offset the part Impact force, in addition, the moving block 8 moves downward to push the cylindrical rod 9 to move upward along the broken line rod 2, and the gravity of the cylindrical rod 9 is used to offset another part of the impact force to realize the buffering function. In this design, the counterweight ball 12 and the cylindrical rod are used 9 Instead of the traditional spring to realize the buffer function, the counterweight b...

The invention relates to the technical field of mining equipment, in particular to an idler device in a conveying structure of mine stones, which includes an idler, a folding line rod, a movable block, a pull rope, a counterweight ball, and a cylindrical rod. When the impact force moves downward, it drives the movable floor and the movable block to move downward, and the movable block moves downward to pull the pull rope, thereby driving the counterweight ball to move upward, and uses the gravity of the counterweight ball to offset part of the impact force. The process of moving down pushes the cylindrical rod to move upward along the broken line rod, and uses the gravity of the cylindrical rod to offset another part of the impact force to realize the buffering function. In this design, the counterweight ball and the cylindrical rod are used to replace the traditional spring to realize the buffering function. The device is used for The counterweight balls, cylindrical rods, movable blocks, and pull ropes that realize the buffering function are not easy to be damaged during frequent shock absorption, and even if damaged, they are more convenient to replace.
Description
technical field [0001] The invention relates to an idler device in a conveying structure of mine stones, which belongs to the technical field of mining equipment. Background technique [0002] General mining machinery is directly used for mineral mining and beneficiation, including mining machinery, prospecting machinery and mineral processing machinery. Generally, a large number of cranes, conveyors, fans and drainage machinery are also used in mining operations. The idler is an important part of the belt conveyor. The function of the idler is to support the weight of the conveyor belt and the material, which has great use value. [0003] When using the conveying mechanism to transport mine stones, etc., due to the heavy weight of the stones, the impact force on the roller during the transportation of the stones is relatively large, and the impact frequency is high. Generally, the spring is set at the bottom of the roller The shock absorption function is realized, but the ...
