[0025] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0026] Depend on Figure 1 Combination Figure 2-5 As shown, an arc-shaped enclosed feeder includes:

[0027] Box 1, the box 1 includes a feed inlet 11 and a discharge outlet 12, and the bottom of the box 1 is provided with an arc-shaped part 13;

[0028] Conveying device 2 is located inside housing 1; the conveying device 2 includes conveyor belt 21, used to convey material from inlet 11 to outlet 12;

[0029] The cleaning device 3 is located inside the housing 1. The cleaning device 3 includes a cleaning belt 31 and a cleaning plate 32. The cleaning plate 32 is located on the cleaning belt 31. The cleaning belt 31 is driven by the cleaning belt 31 and is used to push the material on the arc part 13 to the discharge port 12.

[0030] The drive unit 4 is connected to the conveyor belt 21 and / or the cleaning belt 31 and is used to drive the conveyor belt 21 and / or the cleaning belt 31 to move. The beneficial effects of this invention are that the conveying device allows for rapid material feeding, while the cleaning device, in conjunction with the arc-shaped section, pushes dust that falls into the arc-shaped section inside the box to the discharge port, avoiding material waste. This invention also has the advantages of simple structure, convenient assembly, reliable operation, and long service life. The bottom of the arc-shaped feeder can be cleaned by the cleaning device to avoid raw material waste. In practice, the cleaning device can move synchronously with the conveying device, or it can be driven independently and activated when needed, reducing manual cleaning work and lowering labor costs.

[0031] This utility model also includes a guide plate 5, which is disposed above the conveyor belt 21. The guide plate 5 and the conveyor belt 21 cooperate to form a guide trough 51. The guide trough reduces material spillage during conveying and reduces cleaning and maintenance work.

[0032] The housing 1 is equipped with an adjusting gate 6, which is positioned above the conveyor belt 21 to ensure uniform material feeding. Specifically, the adjusting gate 6 slides in conjunction with the housing 1, and its sliding direction relative to the housing 1 is perpendicular to the movement direction of the conveyor belt 21. More specifically, the adjusting gate 6 is integrally formed from 2.5mm-3.5mm thick stainless steel. An adjustable gate at the feed inlet ensures uniform coal flow; the height of this gate is adjustable, allowing for the setting of coal conveying efficiency as needed. An iron separator or a neodymium iron boron strong magnetic iron removal device (not shown in the figure) can be installed at the feed inlet to prevent damage to the equipment from iron filings and ensure effective removal of iron wires and iron blocks from the coal sample, thereby reducing the system's failure rate.

[0033] This utility model also includes a scraper 7, disposed on the housing 1. The scraper 7 is attached to the outer surface of the conveyor belt 21 and is used to scrape off residual material on the conveyor belt 21. Specifically, this utility model also includes a support plate 16, disposed inside the housing 1; the scraper 7 is disposed at the discharge port 12; the conveyor belt 21 is arranged in a ring shape; the scraper 7 is disposed at the lower part of the center surface of the conveyor belt 21; the support plate 16 is disposed below the upper part of the center surface of the conveyor belt 21 to support the conveyor belt 21. More specifically, the conveyor belt is made of flame-retardant canvas tape, bonded by hot vulcanization and pressure.

[0034] The housing 1 is integrally formed from 304 stainless steel, creating a closed tubular structure. The inlet 11 is located on the upper surface of the housing 1, and the outlet 12 is located on the arc-shaped portion 13 of the housing 1. This utility model's housing adopts an arc-shaped, fully enclosed structure, and is entirely made of 304 stainless steel, effectively preventing dust emission and reducing system moisture loss. This prevents moisture loss and dust dispersion in the coal sample, ensuring the accuracy of the coal sample.

[0035] The housing 1 is provided with multiple observation ports 14, each with a cover plate 15. The observation ports 14 are located radially and / or axially on the housing 1. This structure facilitates observation of the material conveying status within the housing, and makes inspection and maintenance easier.

[0036] This utility model also includes a tensioning device 8, located inside the housing 1. The tensioning device 8 includes a support frame 81, a connecting roller 82, and an adjusting rod 83. The connecting roller 82 is mounted on the support frame 81 and slides in cooperation with it. The conveyor belt 21 and / or the cleaning belt 31 are mounted on the connecting roller 82, and the tension of the conveyor belt 21 and / or the cleaning belt 31 is adjusted by the adjusting rod 83. The tensioning device prevents the conveyor belt and / or cleaning belt from slipping or deviating, ensuring reliable and convenient material conveying. A zero-speed detection switch (not shown in the figure) can also be installed to detect slippage and breakage of the conveyor belt and cleaning belt, and to issue an alarm signal.
