[0031] The specific settings and functions of the adjusting device 5 and the cleaning device 6 will be described in detail below.
[0032] like Figure 2 and Figure 3 as well as Figure 4 As shown, the adjusting device 5 includes a support frame 501, the support frame 501 is fixedly connected to the frame body 1, a servo motor 502 is fixedly connected to the surface of the frame body 1, and a half gear 503 is fixedly connected to the output end of the servo motor 502, a slide groove 504 is opened on the surface of the support frame 501, a spring 505 is fixedly connected to the surface of the slide groove 504, one end of the spring 505 is fixedly connected to a slider 506, the slider 506 is fixedly connected to the detector 4, a rack 507 is fixedly connected to the surface of the slider 506, the rack 507 is meshed with the half gear 503, a baffle 508 is fixedly connected to the surface of the rack 507, the baffle 508 is an iron plate, and the rack 50 7 will drive the baffle 508 to move. At this time, the baffle 508 can prevent the spring 505 from pulling the rack 507 completely into the slide groove 504. The surface of the slide groove 504 is rotatably connected with the ball 509. The ball 509 is slidably connected with the rack 507. The rack 507 will drive the ball 509 to roll. At this time, the ball 509 can reduce the friction between the rack 507 and the slide groove 504. The surface of the slide groove 504 is fixedly connected with a water absorption plate 510. The water absorption plate 510 is a sponge plate. The rack 507 will move along the surface of the water absorption plate 510. At this time, the water absorption plate 510 can wipe the moisture generated by the sand and gravel materials on the rack 507.
[0033] like Figure 2 and Figure 5 As shown, the cleaning device 6 includes two screw rods 61, both of which are threadedly connected to the support frame 501, and the surface of the screw rod 61 is threadedly connected to a connecting plate 62, and the surface of the connecting plate 62 is rotatably connected to a rotating shaft 63, and the arc surface of the rotating shaft 63 is fixedly connected to a wiping ring 64, and the arc surface of the wiping ring 64 is fixedly connected to a plurality of brushes 65, and the plurality of brushes 65 are evenly distributed on the arc surface of the wiping ring 64, and the wiping ring 64 will drive the brushes 65 to move, and at this time the brushes 65 can brush the conveyor belt 3 after being wiped by the wiping ring 64, and the surface of the screw rod 61 is fixedly connected to a connecting rope 66, and the connecting rope 66 is fixedly connected to the connecting plate 62, and the screw rod 61 will drive one end of the elastic rope to move, and at this time the elastic rope can prevent the screw rod 61 from being lost.
[0034] Working principle: when it is necessary to move the detector 4, first start the servo motor 502. At this time, the output end of the servo motor 502 will drive the half gear 503 to rotate. At this time, the half gear 503 will drive the meshing rack 507 to move away from the slide groove 504, and then the rack 507 will drive the ball 509 to roll. At this time, the ball 509 can reduce the friction between the rack 507 and the slide groove 504. Then the rack 507 will drive the slider 506 to move along the surface of the slide groove 504. At the same time, the slider 506 will drive the detector 4 to move in the same direction. Then the slider 506 will drive one end of the spring 505 to move. At this time, the spring 505 itself will generate a retraction tension. At the same time, the rack 507 will move along the surface of the water absorption plate 510. At this time, the water absorption plate 510 can wipe the moisture generated by the sand and gravel materials on the rack 507. Then when the half gear 503 rotates to its own arc surface, the rack 507 will be disengaged from the half gear 503. 504, the gear 507 is moved to the left by the spring 505, and the gear 507 is moved to the right by the spring 505.
[0035] When the surface of the conveyor belt 3 needs to be cleaned, first, the two screw rods 61 are fixed between the support frame 501 by means of their own threads. Then, when the conveyor belt 3 rotates, the conveyor belt 3 will drive the wiping ring 64 to rotate. At this time, the wiping ring 64 will drive the brush 65 to move. At this time, the brush 65 can brush the conveyor belt 3 wiped by the wiping ring 64, and at the same time, the wiping ring 64 will drive the rotating shaft 63 to rotate along the surface of the connecting plate 62. When the cleaning is completed, it is only necessary to rotate the screw rod 61. At this time, the screw rod 61 will move away from the support frame 501 by means of its own threads. At the same time, the screw rod 61 will drive one end of the elastic rope to move. At this time, the elastic rope can prevent the screw rod 61 from being lost. By setting the cleaning device 6, the screw rod 61, the connecting plate 62, the rotating shaft 63 and the wiping ring 64 are used to clean the surface of the conveyor belt 3, so as to avoid a small amount of sand and gravel materials adhering to the surface of the conveyor belt 3 and affecting the rotation effect of the conveyor belt 3, thereby improving the cleanliness of the surface of the conveyor belt 3 and further improving the transmission efficiency.
