[0002] The coal slurry desilting machine in underground coal mines consists of a trough, chain, guideway, drive motor, and scraper. The guideway is fixed inside the trough, and the chain is slidably installed in the guideway, which serves as a guide for the chain. The drive motor is connected to the chain, and the scraper is fixed to the chain. During operation, the drive motor drives the chain, which in turn drives the scraper inside the trough to scrape the coal slurry and other particles inside the trough to the discharge port of the trough. Due to the sliding friction between the chain and the guideway, the chain wears more severely at the bend of the guideway, and the resistance is also greater, which affects the service life of the chain. At the same time, the bend of the guideway also needs to be replaced frequently. Utility Model Content

[0028] The present embodiment provides a pressure roller device for a coal mine underground coal slurry water silt cleaning machine, which is applied to a coal mine underground coal slurry water silt cleaning machine; the coal mine underground coal slurry water silt cleaning machine includes a trough body 11, and the pressure roller device of the coal mine underground coal slurry water silt cleaning machine is arranged in the trough body 11 and is used to guide the chain moving in the trough body 11. For example, when the chain moves in the trough body 11, it needs to transition from the bottom wall to the side wall of the tail. The pressure roller device of the coal mine underground coal slurry water silt cleaning machine is arranged at the tail of the trough body 11 and presses on the chain. When the chain moves to the pressure roller device of the coal mine underground coal slurry water silt cleaning machine, it can be reversed under the action of the pressure roller body 21 of the pressure roller device of the coal mine underground coal slurry water silt cleaning machine, switching from horizontal to vertical.

[0029] The above-mentioned roller device of the coal mine underground slurry desilting machine includes a roller body 21, a main shaft 22, a bearing seat 23, a first bearing 24, and a second bearing 25. The bearing seat 23 is used to support the first bearing 24. Two bearing seats 23 are provided, and correspondingly, two first bearings 24 are provided, with each bearing seat 23 containing a first bearing 24. The trough body 11 has two opposing side walls, which are the side walls in the longitudinal direction of the trough body 11. The two bearing seats 23 are respectively fixed on the two opposing side walls of the trough body 11, and the first bearings 24 in the two bearing seats 23 are coaxially arranged. The bearing seats 23 and the first bearings 24 cooperate to support the main shaft 22. The two ends of the main shaft 22 are respectively inserted into the first bearings 24 of the bearing seats 23 to enable the main shaft 22 to rotate. The main shaft 22 is used to support the roller body 21. The roller body 21 is mounted on the main shaft 22 via the second bearing 25, so that the roller body 21 and the main shaft 22 can also rotate relative to each other.
