1. the whole scraper blade in the prior art adopts a rigid structure, when the rigid object attached to the belt is processed, the rigid object directly impacts the blade edge of the scraper blade, or a spring is added, and when the rigid object impacts the scraper blade, the spring is compressed to avoid opening the rigid object, so that the intractable attachment of the rigid object can not be effectively solved; in the application, the scraper adopts an elastic structure, when a hard object directly impacts the scraper, the cutter body in the scraper slides relatively with the base plate to compress the elastic sheet, thereby achieving the buffer effect, slowing down the direct contact between the hard object and the scraper, reducing the impact abrasion of the scraper and prolonging the service life of the scraper.
2. According to the application, the vibrator is arranged on the rotating shaft, the vibrator drives the scraping plate to vibrate at a certain frequency, when the attachments on the belt are in direct contact with the scraping plate, vibration waves of the scraping plate are transmitted to the attachments, so that the attachments and the belt vibrate relatively, meanwhile, the cutting edge part of the scraping plate cuts the attachments, and hard objects which are stubborn and attached on the belt can be removed by combining the two forms.
3. In practical application, the proportion of hard objects adhered to the belt is small, and unnecessary waste is easily caused by starting the vibrator for a long time; the pressure sensor is arranged in the elastic sheet, when hard objects impact the cutter body, the cutter body extrudes the elastic sheet, so that the pressure sensor is triggered, and after information feedback of the pressure sensor, the vibrator is connected with a circuit to work so as to drive the scraping plate to perform vibration treatment.
4. In the prior art, the outer surface of the scraper adopts a streamline structure, and after the scraper scrapes annual adherends on the belt, the annual adherends are led out through the streamline profile, but when certain attachments with higher viscosity are used outside the scraper, certain residues are accumulated, and the scraping effect of the scraper is easily affected; the scraping plate has the vibrating function, and even if residues are adhered to the scraping plate, the residues fall off in the vibrating process, so that the hanging effect of the scraping plate is ensured.

The belt conveyor also comprises a frame, a vibration reduction mechanism, a driving mechanism and other prior arts, and the innovation point of the application is not in the belt conveyor itself, so the description is not repeated.
As shown in fig. 2, the first cleaner 3 and the second cleaner 4 are both belt 2 cleaners, the belt 2 cleaners include a cantilever 31, a rotating shaft 32, a swing rod 36 and a scraper 33, two sides of the cantilever 31 are oppositely arranged, the rotating shaft 32 penetrates through the cantilever 31 at two sides, the rotating shaft 32 is defined as a horizontal direction, the cantilever 31 is defined as a vertical direction, and a linear direction of an upper end edge of the cantilever 31 is defined as a front-rear direction. The rotating shafts 32 of the cantilevers 31 extending from two sides are sleeved with one ends of the connecting rods 34, the outer sides of the cantilevers 31 are hinged with swing rods 36, the other ends of the connecting rods 34 are sleeved with the swing rods 36, the other ends of the swing rods 36 are fixed on a frame of the belt conveyor, and the cantilevers 31 are also fixed on the frame of the belt conveyor. A tensioning spring 37 is arranged between one end of the swing rod 36, which is far away from the cantilever 31, and the connecting rod 34, namely, one end of the tensioning spring 37 is propped against the connecting rod 34, the other end of the tensioning spring is propped against the baffle, the baffle is in threaded connection with the swing rod 36, and the tensioning degree of the tensioning spring 37 is adjusted by adjusting the position of the baffle. The scraper 33 is mounted on the rotating shaft 32 between the cantilevers 31, and the vibrator 35 is mounted on the cantilever 31 at one side, and the output end of the vibrator 35 is connected with the rotating shaft 32.
In this embodiment, the output end of the vibrator 35 drives the rotating shaft 32 to swing slightly in the circumferential direction, preferably, the swinging range is smaller than 60 °, and more preferably, the swinging angle is 5 °. Preferably, the vibrator 35 oscillates at a frequency of 20-1500 hz, more preferably, the vibrator 35 oscillates at a frequency of 20-1000 hz, and most preferably, the vibrator 35 oscillates at a frequency of 60 hz. When the vibrator 35 drives the rotating shaft 32 to swing circumferentially back and forth, the elasticity of the tensioning spring 37 needs to be overcome, and the tensioning spring 37 can play a role in vibration reduction, so that the influence of the vibrator 35 on the swinging rod 36 is reduced.
As shown in fig. 3, the scraper 33 includes three parts, namely a blade body 331, a base plate 332 and an elastic sheet 333, wherein the base plate 332 is directly and fixedly connected with the rotating shaft 32, the blade body 331 is slidably connected with the base plate 332, and the elastic sheet 333 is disposed in a gap between the blade body 331 and the rotating shaft 32. The sliding direction between the blade body 331 and the base plate 332 is a linear direction of the cross section of the end portion of the squeegee 33, that is, the sliding direction is a vertical direction in the present embodiment. When the blade portion of the blade body 331 is impacted, a force generated upon the impact is a tangential position to the traveling direction of the belt 2, thereby pressing down the elastic piece 333. When the vibrator 35 drives the scraping and swinging, no gap exists between the base plate 332 and the cutter body 331, and the swinging of the scraping plate 33 is free from loss.
As shown in fig. 4, the cutter body 331 and the base plate 332 are fixed by eight bolts.
