[0025] In order to prevent the belt from being stuck with too much soft mud, affecting the belt operation and soil conveying, and sticking to the bottom auxiliary roller, the mud outlet ends of the first roller belt conveyor 210, the second roller belt conveyor 211 and the third roller belt conveyor 212 are all provided with end mud scraping mechanisms and bottom mud scraping mechanisms.

[0026] The end scraper mechanism includes an end scraper plate 220, which is made of elastic rubber material. One side of its blade tangentially abuts against the semicircle of the output end belt, and the lower side is fixedly connected to the end scraper cross tube 221. The two ends of the end scraper cross tube 221 are rotatably connected to the two end scraper bases 222 and extend out of one end of the end scraper base 222. After passing through the end scraper sleeve 223, it is locked with the sleeve locking screw 224. The end scraper base 222 is fixedly connected to the frame side wall plate of the first roller belt conveyor 210, the second roller belt conveyor 211 or the third roller belt conveyor 212. The end scraper sleeve 223 is fixedly connected to a rocker arm 225. The rocker arm 225 is provided with a rocker arm strip through hole 226 arranged along its length direction. The rocker arm strip through hole 226 movably passes through an adjusting screw 227. One end of the adjusting screw 227 is hinged on the hinge shaft 228, and the other end is connected to the hinge shaft 228. It is connected with an adjusting nut 229, and an articulated shaft 228 is fixedly connected horizontally and vertically to the top of the end scraper base 222. The adjusting screw 227 is sleeved with a compression spring 230, and the compression spring 230 is located between the adjusting nut 229 and the rocker arm 225. The end scraper mechanism is installed, which can carry out the initial scraping of the soft soil transported down, and the end belt is against the power roller. Under the tangential scraping action of the scraper plate, the scraped soil can be sent to the feed hopper of the next equipment, reducing the workload of the bottom scraper plate, and also avoiding the bottom scraper plate from hanging on the fallen soil (this soil may not enter the feed hopper because it is far from the end) to avoid affecting the belt operation and sticking to the auxiliary support roller. In addition, the two ends adopt the compression spring elastic structure installation and rocker arm drive compression, which can further realize the tangential elastic contact of the scraper plate, and is also more conducive to the blade hanging on the soft soil.

[0027] The bottom mud scraping mechanism includes a scraper blade 422, which is made of elastic rubber material. One side of its blade rests on the belt, and the lower side is fixedly connected to the horizontal tube 423. The two ends of the horizontal tube 423 are movably embedded in the vertical U-grooves 425 of two inverted U-shaped seats 424, and two sleeves 426 are sleeved on the inner sides of the two ends and locked with locking screws 427. The U-shaped seat 424 is installed on the inner side of the frame side wall plate of the first roller belt conveyor 210, the second roller belt conveyor 211 or the third roller belt conveyor 212. The top of the sleeve 426 is fixedly connected with a screw rod 428. The screw rod 428 passes through a horizontal plate 429 set on the inner side of the upper part of the U-shaped seat 424 and is connected to a nut 430. A compression spring 431 is installed between the nut 430 and the horizontal plate 429, and the compression spring 431 is sleeved on the screw rod 428. The installation of a bottom scraper mechanism can scrape off the soil that is easily adhered during the transportation of soft soil, so as to avoid affecting the operation of the belt and sticking to the auxiliary support rolling. The two ends are installed with a compression spring elastic structure, which can further realize the elastic contact of the scraper. The two sides are connected with sleeves, which is also convenient for adjusting the angle between the scraper and the belt surface, and is more conducive to the blade to hang off soft mud. The two ends of the horizontal tube are inserted into the U-shaped groove, and the screw and nut are used to facilitate the rapid adjustment of the vertical position and the stable connection of the horizontal tube.

[0028] In order to realize remote monitoring, cameras are set at the mud outlet end of the frame side wall plates of the first roller belt conveyor 210, the second roller belt conveyor 211 and the third roller belt conveyor 212. The cameras are set toward the belts to realize soil transportation monitoring.
