Description

Technical Field

[0001] The utility model relates to the technical field of coal conveying, in particular to an anti-blocking mechanism and a blanking device. Background Art

[0002] Coal, also known as coal, is a combustible black or brownish-black sedimentary rock, usually occurring in the rock strata or veins of coal beds or coal seams. In thermal power plants, coal plays a crucial role. At the same time, in the coal storage bin of thermal power generation, the safe and stable operation of the coal conveying system is directly related to the reliable operation of the unit. Blockage and overflow of coal in the coal chute of the belt conveyor are one of the main causes of coal conveying operation accidents.

[0003] Due to coal quality and various factors, blockage and overflow of coal may occur in the coal chute at the head of the belt conveyor. Once blockage occurs, the coal flow on the belt is blocked and instantaneously accumulates, overflowing in large quantities. At the same time, the coal flow will scatter everywhere along the return belt. After the coal chute is blocked, if the whole belt is pressed as a heavy vehicle and not discovered in time, equipment accidents such as motor overload and belt breakage may occur. At the same time, when the existing coal chute is blocked, it is usually necessary to manually knock on the coal conveying pipeline to shake off the coal accumulated on the inner wall of the pipeline through the vibration of the pipeline to achieve dredging. Such a dredging method has low efficiency. Summary of the Utility Model

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0029] Secondly, the so-called "one embodiment" or "embodiment" herein refers to specific features, structures or characteristics that may be included in at least one implementation manner of the present utility model. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments.

This embodiment provides an anti-blocking mechanism, which can realize the convenient loading and unloading of the mobile crushing equipment, make the positioning of the drill bit more accurate during the installation and disassembly process, and make the installation and disassembly process more convenient.

[0032] Specifically, the coal unloading unit 100 includes a housing assembly 101, a dispersing assembly 102 arranged inside the housing assembly 101, and a set of scraping assemblies 103 arranged outside the dispersing assembly 102;

[0033] The installation unit 200 includes a rotating assembly arranged inside the dispersing assembly 102 and a supporting assembly 202 arranged inside the rotating assembly.

[0034] It should be noted that the housing assembly 101 is rotatably connected to the dispersing assembly 102, the scraping assembly 103 is fitted with the dispersing assembly 102, the rotating assembly is fitted with the dispersing assembly 102, and the rotating assembly is fitted with the supporting assembly 202.

[0035] During use, during the process of coal feeding, the coal falls onto the dispersing assembly 102. Under the action of the gravity of the falling coal, the dispersing assembly 102 rotates in cooperation with the rotating assembly and the supporting assembly 202. The rotation of the rotating assembly drives the scraping assembly 103 and the dispersing assembly 102 to rotate.

[0045] Furthermore, the rotating assembly includes a rotating rod disposed inside the dispersing assembly 102, a limiting hole disposed on one side of the rotating rod, and a set of limiting grooves disposed outside the limiting hole. The limiting grooves are symmetrically arranged. Among them, the rotating rod is fixedly connected to the connecting plates 102a.

[0046] It should be noted that clamping grooves are symmetrically opened on the outer sides of both ends of the rotating rod, and the clamping rods 103c are fitted and installed inside the clamping grooves, and the connecting plates 102a all adopt inclined surfaces.

[0047] Further, the support assembly 202 includes a support rod 202a disposed inside the rotating rod, fixing rods 202b disposed at both ends of the support rod 202a, and a set of sliding strips 202c disposed outside the support rod 202a.

[0049] During use, the coal is conveyed into the interior of the feeding hopper 101b by the conveyor 101c, and falls into the interior of the feeding pipe 101a through the feeding hopper 101b. The coal falls onto the connecting plate 102a during the falling process. Under the action of the gravity of the coal, the connecting plate 102a flips downward. During the flipping process of the connecting plate 102a, the rubber scraper 102b is driven to rotate. The connecting plate 102a drives the rotating rod to rotate. The rotation of the rotating rod drives the circular connection blocks 103a installed at both ends to rotate. The rotation of the circular connection blocks 103a drives the arc-shaped plates 103b installed on the outer wall to rotate. The rotation of the arc-shaped plates 103b can scrape off the coal adhering to the inner wall of the feeding pipe 101a, preventing coal blockage inside the feeding pipe 101a. The connecting plate 102a drives the rubber scraper 102b to rotate, and one end of the rubber scraper 102b fits against the inner wall of the feeding pipe 101a. The rubber scraper 102b can scrape off the coal adhering to the inner wall of the feeding pipe 101a when rotating.

[0050] In summary, the beneficial effect of an anti-blocking mechanism is that the falling coal can be scattered by the scattering assembly 102, avoiding lumps in the falling coal. At the same time, it can also prevent the coal from accumulating on the inner wall of the housing assembly 101, resulting in coal blockage. At the same time, the scraping assembly 103 can scrape off the coal powder adhering to the inner wall of the housing assembly 101, avoiding the formation of an arch due to the accumulation of coal powder on the inner wall of the housing assembly. The cooperation with the rotating assembly enables the scraping assembly 103 to clean the inner wall of the housing assembly 101 for a long time, preventing the accumulation of coal powder.
