Single-gas-path adjustable pusher dog for coal gangue sorting

Abstract

The invention discloses a single-gas-path adjustable pusher dog for coal gangue sorting. The single-gas-path adjustable pusher dog comprises a base plate provided with a static pusher dog, a rotating air cylinder arranged below the base plate, a first locking piece which is connected with the rotating air cylinder, is provided with a movable pusher dog and is driven by the rotating air cylinder to rotate so as to drive the movable pusher dog to be close to or away from the static pusher dog, a locking assembly which is arranged on the base plate and is provided with a second locking piece, and a gas supply assembly; the rotating air cylinder and the locking assembly are connected with the gas supply assembly, when the gas supply assembly starts to supply gas, the second locking piece moves away from the first locking piece, and meanwhile, the movable pusher dog moves close to or away from the static pusher dog; when the gas supply assembly stops supplying gas, the second locking piece moves close to the first locking piece and abuts against the first locking piece, and meanwhile, the relative positions of the movable pusher dog and the static pusher dog are fixed. According to the single-gas-path adjustable pusher dog, two actions of rotating and locking are simultaneously controlled by a single gas path.

Description

technical field [0001] The invention belongs to the technical field of claws, and in particular relates to a single-gas-path adjustable claw for coal gangue sorting. Background technique [0002] Coal gangue sorting is an important link in the process of coal sorting and processing. At present, because the positions of coal gangue are different, mechanical hands are usually used for sorting. In the existing technology, mechanical grippers are usually used to grab coal gangue. Because the positions of the stones are staggered and stacked, the mechanical gripper cannot lift all the grippers to the coal gangue. At present, the puller sorts the coal gangue in the way of flipping. However, due to the different positions and sizes of each coal gangue, after the puller is used for a long time, there is an error in the adjustment of the distance between the claws. Thus affecting the sorting process. Contents of the invention [0003] The present invention aims to solve at least ...

Problems solved by technology

At present, because the positions of coal gangue are different, mechanical hands are usually used for sorting. In the existing technology, mechanical grippers are usually used to grab coal gangue. Because the positions of the stones are staggered and stacked, the mechanical gripper cannot lift all the grippers to the coal gangue. At present, the puller adopts the method of pulling to sort the coal gangue. However, due to the different positions and sizes of each coal gangue, after the puller is used for a long time, there is an error in the adjustment of the distance between the claws. thereby affecting the sorting process
