Embodiment 1
[0046] Such as figure 1 , 3 , 8, and 9, the vibrating screen of the present invention is mainly composed of a screen frame 1, a screen cloth 2, a grid frame 3, a vibrating motor 4, a base 5, a vibrating spring 6 and a vibrating body 7. The grid frame 3 is located in the cavity surrounded by the screen frame 1, and an annular cavity is formed between the grid frame 3 and the screen frame 1. The screen cloth 2 is tightened on the grid frame 3 by stretching hoops 9 . A homogenizer 18 is set above the screen 2, and there is a gap between the homogenizer 18 and the screen 2; a connected hopper 19 and a distribution pan 20 are arranged in the homogenizer 18, and a discharge channel 19.1 is provided at the lower end of the hopper 19. , The bottom of the cloth pan 20 is provided with a cloth opening 20.1. The cloth opening 20.1 is arc-shaped. The edge of the distribution pan 20 is provided with a shroud 20.2, and the middle portion of the shroud 20.2 near the center of the screen ...
Embodiment 2
[0061] Compared with Embodiment 1, in this embodiment, the ends of the stretching hoops 9 are still intersected after passing through the screen frame 1 . The difference from Embodiment 1 is that in this embodiment, the stretching net hoop 9 is tightened by straight pulling. Such as Figure 6 As shown, the locking buckle 13 is fixed at the end of the stretching hoop 9, and the hook 12 is fixed on the outer wall of the screen frame 1. Pull the locking buckle 13 by hand to pull one end of the stretching net hoop 9 forward, hang it on the hook 12 after tightening, and then pull the locking piece of the locking buckle 13 to close the stretching net hoop 9 Tight fix.
[0062] This embodiment does not need tools to tighten, only needs to be pulled by hand, the advantage is that it is faster.
[0063] In Embodiments 1 and 2 above, the ends of the stretching hoops 9 pass through the screen frame 1 and then intersect, so that the screen 2 is tightened in the external space of the sc...
Embodiment 3
[0065] Different from Embodiments 1 and 2, in this embodiment, the stretching hoops 9 do not need to pass through the screen frame 1 . Such as Figure 7 As shown, the stretching hoops 9 of the same layer are two semicircles, and the two stretching hoops 9 are correspondingly arranged to form a ring, and the end of one stretching hoop 9 is connected to the end of the other stretching hoop 9. The corresponding ends are relatively close to each other. Fix the coupling piece 16 at the end of the stretching net hoop bar 9, penetrate the fastening bolt 14 in the two relative coupling pieces 16, and set the nut 15 on the fastening bolt 14.
[0066] An operating hole 1.3 is set at the position of the screen frame 1 corresponding to the end of the stretching hoop 9, and a wrench is inserted into the operating hole 1.3 to turn the nut 15, and the two stretching hoops 9 are relatively tightened, and the screen 2 Straighten it up and say no more. The meaning of opening the operation ho...
