The two groups of stands are connected as a whole by connecting rods 14 arranged along the width direction of the belt, ensuring the stability of the whole support, and the support will not interfere with the belt. Further, long holes are arranged along the length direction on the column, the upper crossbeam and the lower crossbeam, and a plurality of connecting rods pass through the long holes to connect the upper crossbeam and the column, the lower crossbeam and the column, the upper crossbeam and the upper crossbeam, and the lower crossbeam and the lower crossbeam, and are locked by nuts 15 arranged on both sides of the connecting rods. The height of the upper crossbeam and the lower crossbeam can be adjusted by adjusting the position of the connecting rod in the long hole, so as to adapt to belts of different heights.

[0023] In the embodiment, the two groups of stands are each connected with a support crossbeam 16 located below the belt, and specifically, the support crossbeam is connected between the two columns along the direction of belt travel and located between the upper crossbeam and the lower crossbeam. Further, the support crossbeam and the column are also connected by connecting rods and locked by nuts. The height of the support crossbeam, i.e. the distance between the support crossbeam and the lower surface of the belt, can be adjusted by adjusting the position of the connecting rod on the long hole of the column on the support crossbeam. In the embodiment, the support is provided with four columns, two upper crossbeams, two lower crossbeams, two support crossbeams and ten connecting rods.

[0024] ​The scraper is rotatably installed between the two supporting beams, and the blade of the scraper is arranged along the width direction of the belt. The end of the scraper away from the blade is suspended with a counterweight ring 4, so that the blade of the scraper is closely attached to the lower plane of the belt, and the direction of the blade of the scraper is opposite to the direction of the belt. When the belt advances, the scraper scrapes off the material adhered to the belt, thereby achieving the purpose of cleaning. Preferably, the scraper is provided with two groups of scrapers in parallel. Specifically, the scraper includes a scraper body 21 and a scraper support plate 22, and the scraper body is made of metal or non-metal material. The scraper support plate is provided with two groups, and the middle part of the two groups of scraper support plates is rotatably installed on the bracket at the two sides of the belt (i.e. on the two supporting beams), and the two groups of scraper support plates are symmetrical, and the two ends of the scraper body are installed between the two groups of scraper support plates. Specifically, one end of the scraper support plate is provided with a clamping groove for installing the scraper body, and the other end of the scraper support plate is provided with a hook for suspending the counterweight ring. Further, the scraper body is installed in the clamping groove on the scraper support plate and locked by a jack screw 23.

[0025] In the embodiment, the rotating shaft 24 arranged along the width direction of the belt is rotatably connected to the bracket (i.e. between the two supporting beams) through the bearing 25, and the two groups of scraper support plates are fixed to the two ends of the rotating shaft, and the rotating shaft rotates to drive the two groups of scraper support plates to rotate. Specifically, the end shaft head 26 of the rotating shaft is located in the shaft hole arranged in the middle part of the scraper support plate, and the end shaft head is fixed in the shaft hole by the jack screw.
