DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0021] A magnesia-carbon brick recycled material screening device comprises a frame 1, a conveyor belt body 2 is arranged in the frame 1, a side stop frame 3 is fixedly installed on the upper surface of the frame 1, a C-shaped movable frame 4 is rotatably installed in the side stop frame 3, a screen frame 5 is slidably installed in the C-shaped movable frame 4, a discharge port is arranged at the left end of the screen frame 5, and the left end of the screen frame 5 is higher than the right end, a return spring 6 is fixedly installed between the screen frame 5 and the C-shaped movable frame 4, a toggle device 7 for toggling the screen frame 5 to slide to the left is installed in the C-shaped movable frame 4, a support beam 31 is fixedly installed in the side stop frame 3, and a lifting device 8 is installed between the support beam 31 and the right side of the C-shaped movable frame 4;

[0022] It should be noted that the right end of the screen frame 5 is provided with an arc portion 51, and the toggle device 7 includes a rotating rod 71, a driving motor 72 and a plurality of cams 73. The rotating rod 71 is rotatably mounted on the right side of the inner cavity of the C-shaped movable frame 4, and the front end of the rotating rod 71 penetrates the front surface of the C-shaped movable frame 4, the driving motor 72 is fixedly mounted on the front surface of the C-shaped movable frame 4, and the output end of the driving motor 72 is fixedly connected to the front end of the rotating rod 71, and the cams 73 are all sleeved on the outer surface of the rotating rod 71, and the cams 73 are rotated about the axis of the rotating rod 71 and contact the arc portion 51;

[0023] When in use, the magnesium carbon brick recycled material to be screened is put into the screen frame 5, and then the driving motor 72 is started. The driving motor 72 drives the cam 73 to rotate through the rotating rod 71. When the cam 73 contacts the arc portion 51 of the screen frame 5, the screen frame 5 is pushed to move forward. When the cam 73 is out of contact with the arc portion 51, the screen frame 5 will move left and reset under the action of the reset spring 6. As the cam 73 continues to contact the arc portion 51, the screen frame 5 moves left and right in a cycle to achieve the purpose of screening the material. The screened fine material is blocked by the side stop frame 3 and falls directly onto the conveyor belt body 2. At this time, the screen frame 5 is used for screening. The fine material is transported to the right by the conveyor belt main body 2 and stacked. When the transport of the fine material is completed, the transport direction of the conveyor belt main body 2 is changed to the left. The right end of the C-shaped movable frame 4 is lifted by the jacking device 8, and the right end of the screen frame 5 in the C-shaped movable frame 4 is lifted accordingly. When the right end of the screen frame 5 is higher than the left end, the coarse material screened will fall from the discharge port on the left side of the screen frame 5 onto the conveyor belt main body 2 under the action of gravity, and then the coarse material can be transported to the right by the conveyor belt main body 2 for stacking. Compared with the prior art, the entire material unloading process of the utility model is more convenient and simple, and can improve the screening efficiency.

[0024] Specifically, if Figure 1 or Figure 2 As shown, the jacking device 8 includes a first adapter block 81, a second adapter block 82 and a hydraulic telescopic column 83. The first adapter block 81 is fixedly installed on the right side of the C-type movable frame 4, and the second adapter block 82 is fixedly installed on the upper surface of the support beam 31. The top end of the hydraulic telescopic column 83 is rotatably connected to the first adapter block 81, and the bottom end of the hydraulic telescopic column 83 is rotatably connected to the second adapter block 82. The extension of the hydraulic telescopic column 83 can drive the right end of the C-type movable frame 4 to lift, thereby driving the right end of the screen frame 5 to lift, and the contraction of the hydraulic telescopic column 83 can drive the right ends of the C-type movable frame 4 and the screen frame 5 to move down and reset.

[0025] Specifically, the C-shaped movable frame 4 and the side stop frame 3 are connected via a flip axis, and the C-shaped movable frame 4 and the side stop frame 3 are rotationally connected via the flip axis, and the flip axis is set in the middle of the C-shaped movable frame 4.

[0026] Specifically, if Figure 6 As shown, four limiting guide rails 41 are fixedly installed on the inner side wall of the C-shaped movable frame 4. Figure 5 As shown, track wheels 52 are rotatably mounted on the front and rear sides of the screen frame 5 , and the track wheels 52 are rollingly set between the upper and lower limiting guide rails 41 to achieve sliding setting of the screen frame 5 in the C-shaped movable frame 4 .
