[0018] Reference Figure 1-5, a dust-proof material receiving device for a crusher comprises a crusher body 1 and a material receiving box 2. A lower hopper 11 is fixedly connected to the bottom of the crusher body 1. The outer surfaces of both ends of the lower hopper 11 are fixedly connected to triangular blocks 12. The two triangular blocks 12 are fixedly connected to inclined blocks 13 at the angles between them and the lower hopper 11. The bottom edges of the two triangular blocks 12 are fixedly connected to connecting seats 14. The inner surfaces of the two connecting seats 14 are rotatably connected to connecting plates 15. The two connecting plates 15 are fixedly connected to the oblique ends of the inclined blocks 13 with a plurality of first springs 16. The tops of one ends of the two connecting plates 15 are fixedly connected to material blocking plates 17.
[0019] A rectangular groove 21 is provided at the upper end of the inner surface of one side of the material receiving box 2, a first discharge port 22 is provided through the lower end of one side of the material receiving box 2, and a second discharge port 23 is provided through the other side of the material receiving box 2. The inner walls on both sides of the second discharge port 23 are rotatably connected with a rotating shaft 24, and a sieve plate 3 is fixedly connected between the two rotating shafts 24. A plurality of second springs 31 are fixedly connected to the bottom of one end of the sieve plate 3, and the plurality of second springs 31 are fixedly connected to the rectangular groove 21.
[0020] Furthermore, the two baffle plates 17 correspond to the bottom opening end of the lower hopper 11 , and the gravel inside the lower hopper 11 will fall onto the baffle plates 17 .
[0021] Furthermore, a connecting plate 18 is fixedly connected to the bottom of a connecting plate 15, and a pressure roller 19 is rotatably connected to the bottom of the connecting plate 18. The connecting plate 15 will drive the pressure roller 19 to move downward through the connecting plate 18.
[0022] Furthermore, the sieve plate 3 and the guide plate 4 are both arranged in an inclined shape, which can facilitate the unloading of the sieve plate 3 and the guide plate 4 .
[0023] Furthermore, a connecting pipe 5 is fixedly embedded at the upper end of one side of the material receiving box 2, a fan 51 is provided inside the connecting pipe 5, and one end of the connecting pipe 5 is fixedly connected to a collecting box 6. When the fan 51 is started, dust can be sucked into the collecting box 6 through the connecting pipe 5.
[0024] When the crusher 1 is in operation, the crushed stones will fall down through the lower hopper 11 and fall onto the two baffle plates 17 to be subjected to force. The baffle plates 17 will stretch the first spring 16 through the connecting plate 15. At this time, the connecting plate 15 will rotate along the connecting seat 14, so that the baffle plates 17 can buffer the impact of the crushed stones falling. The connecting plate 15 will drive the pressure roller 19 to move downward through the connecting plate 18. At this time, the pressure roller 19 will press the screen plate 3 downward to compress the second spring 31. The screen plate 3 will rotate along the inner wall of the second discharge port 23 through the rotating shaft 24, so that the screen plate 3 will shake up and down to increase the screening effect, and then the larger crushed stones will slide out through the second discharge port 23. When the crushed stones screened by the screen plate 3 fall onto the guide plate 4 and slide out through the first discharge port 22, in this process, starting the fan 51 can suck the dust into the collection box 6 through the connecting pipe 5 to avoid environmental pollution caused by dust.
