[0026] In this embodiment, reference Figure 2 and Figure 3 The adjusting mechanism 2 includes an adjusting rod 201 slidably connected to the inside of the counterattack main board 1, a fixed sleeve 202 is fixedly connected to the outer wall of the counterattack main board 1 at the corresponding position of the adjusting rod 201, a first counterattack sub-plate 203 is slidably connected to the outer wall of the adjusting rod 201 at a position close to the counterattack main board 1, a second counterattack sub-plate 204 is fixedly connected to the outer wall of the adjusting rod 201 at an end away from the counterattack main board 1, and a limited block 205 is slidably connected to the outer wall of the adjusting rod 201 in the first counterattack sub-plate 203. The outer wall of the limit block 205 is fixedly connected with a micro electric push rod 206 in the adjusting rod 201, the outer wall of the first counterattack sub-plate 203 is fixedly connected with an electromagnet 207 on the side close to the counterattack main plate 1, the outer wall of the adjusting rod 201 is fixedly connected with a piston plate 208 in the fixed sleeve 202, the interior of the fixed sleeve 202 is fixedly connected with an air pump 209 at a position close to the piston plate 208, and the outer wall of the piston plate 208 is fixedly connected with a return spring 210 at a position close to the air pump 209;

[0027] The adjusting rod 201, the first counter-attack plate 203 and the second counter-attack plate 204 are all made of wear-resistant parts. The first counter-attack plate 203 and the second counter-attack plate 204 are both designed with arc structures. The connection mode of the reset spring 210 and the fixed sleeve 202 is fixed connection. The micro electric push rod 206 and the limit block 205 are provided with four groups. The adjusting rod 201 passes through and extends to the outside of the counter-attack main board 1. The limit block 205 and the first counter-attack plate 204, the adjusting rod 201 and the fixed sleeve 202, the piston plate 208 and the fixed sleeve 202 are all connected in a sliding manner, the arc length of the first counterattack sub-plate 203 is one eighth of the circumference of the counterattack main plate 1, both sides of the first counterattack sub-plate 203 and the second counterattack sub-plate 204 are designed in a stepped shape, the arc length of the second counterattack sub-plate 203 is one half of the arc length of the first counterattack sub-plate 203, the micro-electric push rod 206, the electromagnet 207 and the air pump 209 are all connected to the terminal 3 in an electrical manner, and the counterattack main plate is connected to the terminal 3. Plate 1 is installed in the vertical impact crusher, and the terminal 3 is connected to the vertical impact crusher controller by a wire. The vertical impact crusher is started, and the material enters the vertical impact crusher. The impeller in the vertical impact crusher drives the material to rotate, and the rotating material is ejected from the impeller gap. The ejected material will be crushed by the impact main board 1, and the controller starts the air pump 209, and the air pump 209 sends air into the fixed sleeve 202. The air entering the fixed sleeve 202 will drive the adjusting rod 201 to move outward through the piston plate 208.

[0028] The working process of the utility model is as follows: when the impact plate adjustment device for a vertical impact crusher designed by the present invention is in operation, the impact main board 1 is installed in the vertical impact crusher, the terminal 3 is connected to the vertical impact crusher controller by a wire, the vertical impact crusher is started, the material enters the vertical impact crusher, the impeller in the vertical impact crusher drives the material to rotate, the rotating material is ejected from the impeller gap, and the ejected material is crushed by the impact main board 1;

[0029] When the crushing effect needs to be improved, the controller starts the air pump 209, and the air pump 209 sends air into the fixed sleeve 202. The air entering the fixed sleeve 202 drives the adjusting rod 201 to move outward through the piston plate 208, and the controller turns off the electromagnet 207. The electromagnet 207 no longer attracts the impact main board 1, and the outward-moving adjusting rod 201 drives the first impact sub-plate 203 to move inward through the limit block 205. The first impact sub-plate 203 moving inward will close together. The closed first impact sub-plate 203 will reduce the jet distance of the material, increase the number of rebounds of the material between the first impact sub-plate 203 and the impeller, and improve the crushing effect.

[0030] When it is necessary to further improve the crushing effect, the air pump 209 sends air into the fixed sleeve 202, and the controller starts the micro electric push rod 206. The micro electric push rod 206 will drive the limit block 205 to enter the adjusting rod 201. The limit block 205 no longer blocks the first impact plate 203. The air entering the fixed sleeve 202 will drive the adjusting rod 201 to move outward through the piston plate 208. The outward moving adjusting rod 201 pushes the second impact plate 204 to move inward. The inward moving second impact plate 204 will close together. The closed second impact plate 204 will further reduce the jet distance of the material, increase the number of rebounds of the material between the second impact plate 204 and the impeller, and further improve the crushing effect.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
