[0002] Traditional sludge dredging machines typically consist of a head section, a transition section, a horizontal section, and a tail section. The head section is angled, the transition section is a π / 4 arc connecting the head and horizontal sections, and the tail section is a π / 2 arc located at the end of the horizontal section away from the transition section. The sludge dredging machine's trough contains scrapers and a chain that works with them. A drive motor is connected to the scrapers via the chain, driving the scrapers to slide within the trough and scrape the coal sludge to the discharge port. The guide rails within the trough, which restrict the chain's sliding direction, correspond to the trough's structure. This results in greater resistance when the chain slides to the π / 2 arc of the guide rail, leading to increased chain wear and a shorter chain lifespan, requiring frequent replacements and impacting production.

[0030] This utility model provides a guide channel for an underground coal slurry dredging machine, used in an underground coal slurry dredging machine. The underground coal slurry dredging machine includes a trough, a chain, a scraper, and a drive motor. The drive motor is mounted on the trough and is connected to the scraper via the chain. The guide channel described above is provided inside the trough to restrict the sliding direction of the chain within the trough. In use, the drive motor drives the scraper to move within the trough via the chain, thereby scraping the coal slurry in the trough to the discharge port and discharging it outwards.

[0031] The guide channel for the coal slurry dredging machine in an underground coal mine provided in this embodiment includes: a first inclined section 11, a first transition section 12, a first horizontal section 13, a second transition section 14, and a second inclined section 15. The first inclined section 11, the first transition section 12, the first horizontal section 13, the second transition section 14, and the second inclined section 15 are connected sequentially to form the guide channel for guiding the chain in the underground coal slurry dredging machine within the trough. The first transition section 12 is located between the first inclined section 11 and the first horizontal section 13 for chain transition and also matches the existing trough. The second transition section 14 is located between the second inclined section 15 and the first horizontal section 13, also for chain transition.

The wear-resistant plate 16 and the angle steel 17 are detachably connected by countersunk bolts, and the other side of the angle steel 17 is welded to the inner wall of the tank. During use, when the wear-resistant plate 16 is worn, the corresponding section of the wear-resistant plate 16 can be directly replaced, which facilitates the inspection and maintenance of the coal slurry dredging machine in the coal mine.

[0038] Another embodiment of this utility model provides a trough for a coal slurry dredging machine in an underground coal mine, including the guide channel of the coal slurry dredging machine described in any of the above embodiments. The guide channel of the coal slurry dredging machine is located within the trough of the coal slurry dredging machine in this embodiment. By providing the guide channel, the trough of the coal slurry dredging machine in this embodiment reduces wear on the chain during operation and extends its service life.

[0044] In this embodiment, after the structure of the trough of the underground coal slurry sludge cleaning machine is modified, a second discharge port can be opened on the trough. The first discharge port 26 is used to discharge large particles of coal slurry, while coal slurry in a muddy state cannot be discharged from the first discharge port 26 due to its high fluidity. Preferably, in this embodiment, a second discharge port 27 is provided on the bottom wall of the second horizontal section 23 near the fourth transition section 24 to discharge coal slurry in a muddy state. The drive motor drives the chain to drive the scraper to move in the first direction. The scraper can scrape large particles of coal slurry to the first discharge port 26. When the drive motor drives the chain to drive the scraper to move in the second direction, the scraper can scrape coal slurry in a muddy state to the second discharge port 27. The first direction and the second direction are opposite.

[0048] The coal mine underground coal slurry dredging machine provided in this embodiment, such as Figure 3 As shown, the mud tank 31 is located directly below the second discharge port 27.

[0049] Preferably, in this embodiment, the mud tank 31 is directly located below the second discharge port 27, which facilitates the arrangement of the mud tank 31. At the same time, there is no need to set up too many pipe structures to connect the second discharge port 27 and the mud tank 31, making the structure simpler and the cost lower.
