Description

Technical Field

[0001] This utility model belongs to the technical field of disc feeders, specifically relating to a disc feeder with anti-jamming capability. Background Technology

[0002] Disc feeders are a type of coal blending equipment, such as... Figure 1 As shown, the disc feeder mainly consists of an adjusting sleeve 1, a housing 2, a disc 3, a scraper 5, a drive mechanism, and a coal blending trough 11. The housing 2 is equipped with a coal outlet 4. The drive mechanism includes a motor 9, a reducer 10, and a rotating shaft 12. The main body of the disc feeder is located below the coal blending trough 11. Coal falls from the discharge port of the coal blending trough 11 through the adjustable sleeve 1, which is mounted at the bottom of the coal blending trough 11, onto the rotating disc 3. The coal is then scraped by the adjustable-angle scraper 5 through the coal outlet 4 onto the coal blending belt conveyor.

[0003] As the disc 3 rotates, the coal chunks falling onto it are resisted by the scraper plate 5, and most of them fall into the outlet 4 to enter the next process. However, a small portion of coal chunks still fall uncontrollably into the area between the lower surface of the disc 3 and the upper surface of the outer shell 2. Over time, more and more coal chunks accumulate between the disc 3 and the outer shell 2, which affects the rotation of the disc 3. In severe cases, it can even cause jamming, affecting the normal operation of coal blending. The usual solution is to shut down the machine and manually clean the accumulated coal with a lever-like tool. However, this method is time-consuming and labor-intensive. Furthermore, due to the complex structure of the disc feeder, it is very difficult to clean the coal accumulated in some corners, resulting in poor cleaning results. Utility Model Content
