Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coal stacking and reclaiming devices, in particular to an automatic coal stacking and reclaiming device. Background Art
[0002] Fuel is coal that can be burned, also known as coal. After being mined, it is piled together and usually transported by a circular coal yard stacker and reclaimer. The column structure of the circular coal yard stacker and reclaimer is driven, and the stacker and reclaimer moves around the column structure, raking the accumulated coal to the ground through several rake teeth, and then through a series of movements of the scraper mechanism, the scraper scrapes the material away from the center to the center of the stacker and reclaimer, falls into the transfer chute, and then the belt conveyor under the stacker and reclaimer transports the material away, realizing the material removal of the coal pile.
[0003] Rake teeth rakes usually adopt crawler walking form, and take materials by rotating and moving. Due to the frequent contact between the rake teeth and the coal, the rake teeth are severely worn after long-term use and need to be replaced. The common replacement method is to replace the whole rake. If the wear degree of the rake teeth at the edge is not enough to replace it, the whole rake will cause a certain degree of resource waste. Therefore, an automatic coal pile reclaiming device is proposed to solve the above problems. Utility Model Content
[0004] The utility model aims to provide an automatic coal stacking and taking device to solve the problem that the coal tooth rakes cannot be replaced individually.

[0007] Preferably, one end of the rotating rod is configured to have a gradually decreasing diameter, and a rubber sleeve is fixedly connected to the outer side of the rotating rod.
[0008] Preferably, the inner sides of the first arc-shaped sleeve and the second arc-shaped sleeve are tightly fitted with the rotating rod, and the recessed part of the rotating rod is tightly fitted with the positioning rod.
[0009] Preferably, a handle having a spherical end is fixedly connected to one side of the first arc-shaped sleeve, and a wear-resistant layer is fixedly connected to one side of the rake teeth rake.
[0010] Preferably, the first arc-shaped sleeve and the second arc-shaped sleeve are arranged in a ring shape after being fitted together, and the moving rods are arranged in a group of four in the second arc-shaped sleeve.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] In the utility model, by providing a device body, a fixing frame, a protective shell, a rotating shaft, a rotating rod, a fixing sleeve, a first arc sleeve, a second arc sleeve, a rake tooth rake and a connecting piece, when the rotating shaft rotates, the rotating rod and the rake tooth rake are driven to rotate around the rotating shaft. Since the rake tooth rake is arranged in a bent manner, during the rotation process, the coal pile on the ground is taken, so that the coal is transported to the transmission device on the left side to achieve the purpose of taking materials. By providing the moving rod, the groove, the positioning rod, the fixing plate and the bolt, the user can use a screwdriver to remove the bolts when replacing the rake tooth rake, and then Then the first arc sleeve is moved up until the positioning rod is away from the depression of the rotating rod, and then the fixing sleeve is removed from the outer side of the rotating rod as a whole, driving the rake tooth rake to be removed as a whole, and then a new rake tooth rake can be installed in the same way. The separate disassembly and assembly structure provided for the rake tooth rake can be replaced or maintained according to the degree of wear. The wear-resistant layer provided on one side of the rake tooth rake increases the wear-resistant effect of the rake tooth rake. The rubber sleeve provided on the outer side of the rotating rod increases the friction between the fixing sleeve and the rotating rod, making it more stable after insertion and not easy to move.
