Figure 4 As shown, a plurality of holes are arranged inside each sieve hole group 203 for screening coke;

[0030] The connecting plate 201 is located in the middle of one side close to the extension plate 205 and is rotatably connected with a threaded rod 207. One end of the threaded rod 207 penetrates into the threaded sleeve 206, and the outer wall of the threaded rod 207 is threadedly sleeved with the inner side of the threaded sleeve 206. The length direction of the threaded rod 207 is consistent with the length direction of the connecting plate 201. The inner wall of the threaded rod 207 is slidably connected with a rotating rod 209. One end of the inner wall of the threaded rod 207 extends into the inner wall of the rotating rod 209 and is fixedly connected with a return spring 213. The other end of the return spring 213 is connected to the rotating rod 209. The inner wall of the rod 209 is fixedly connected, one end of the rotating rod 209 passes through the threaded rod 207 and is fixedly installed with a knob 208, the end of the rotating rod 209 located away from the knob 208 passes through the inner wall of the connecting plate 201 and is fixedly connected with a plate 210, a plurality of connecting grooves 211 are opened on the surface of the plate 210, and the connecting grooves 211 are arranged in an annular shape along the side of the plate 210 at equal distances, and the inner wall of each connecting groove 211 is slidably connected with a connecting shaft 212, and one end of the connecting shaft 212 is fixedly connected to the inner wall of the connecting plate 201, such as Figure 5-Figure 6 As shown, the connecting shaft 212 is inserted into the connecting groove 211, so the abutment plate 210 cannot rotate, and the rotating rod 209 cannot drive the screw rod 207 to rotate as a whole;

[0031] The vibrating screen body 1 also includes a base 101, and support springs 106 are fixedly connected to the top of the base 101 on all sides, and the tops of the support springs 106 are commonly connected to a screen box 107. A feed inlet 109 is provided at one end of the top of the screen box 107, and a discharge port 110 is provided in the middle of the bottom of the screen box 107. The upper and lower ends of the inner wall of the screen box 107 are fixedly connected to the connecting plate 201, and a guide plate 108 is fixedly connected to the side wall of the screen box 107 and close to the connecting plate 201.

[0033] The working principle of this utility model:

[0034] When the device is in use, the motor 103 is started to drive the eccentric block 104 to rotate, and the eccentric block 104 drives the screen box 107 to shake on the top of the support spring 106 under the action of the centrifugal force, and then the coke to be screened is introduced into the screen box 107 through the feed port 109, and the coke falls on the surface of the connecting plate 201, and the smaller coke falls on the surface of the next layer of connecting plate 201 through the sieve hole group 203, and then the smaller coke passes through the bottom sieve hole group 203 and enters the collection box 105. Among them, the coke that cannot be screened on the surface of the connecting plates 201 on both sides falls into the guide plate 108 and is then discharged;

[0035] Secondly, when it is necessary to adjust the actual screening aperture of each sieve hole group 203, pull the knob 208 outward, at this time, the stop block 210 moves and the connecting groove 211 is separated from the connecting shaft 212, and then rotate the knob 208 to drive the threaded rod 207 to rotate through the rotating rod 209, so that the thread on the surface of the threaded rod 207 pushes the threaded sleeve 206, and drives the extension plate 205 to move, and the baffle 204 moves under the limit of the slide groove 202. At this time, the inner part of the sieve hole group 203 is covered by the baffle 204 below, thereby changing the size of coke that can be screened by the sieve hole group 203.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
