By rotating the adjusting nut 408 in the forward direction, the adjusting screw 403 can be pulled out of the housing 1 under the abutment and elastic force of the spring body 406, the first spring base and the second spring base, so that the gap between the counter-attack component 2 and the rotating striking component 3 can be increased, and the gap between the counter-attack component 2 and the rotating striking component 3 can be decreased by rotating the adjusting nut 408 in the reverse direction.

[0032] The working principle of the impact crusher of the utility model which is convenient for quick installation of the return lining plate is as follows:

[0033] When in use, the belt is connected to the motor of the external device through the pulley 304, so that the rotation of the external motor can drive the striking plate 309 to rotate, and then the material is poured from the feed port 5. The material enters the housing 1 and is knocked to the return lining plate 205 by the rotation of the striking plate 309, so that the material can be crushed into small particles and finally fall from the discharge port 6. Further, when adjusting the counter-attack component 2, it is only necessary to adjust the forward and reverse rotation of the adjustment nut 408 at the corresponding position, and the elastic force and abutment force of the spring body 406, the first spring base and the second spring base can be used to adjust the gap between the return lining plate 205 in the counter-attack component 2 and the striking plate 309 in the rotating striking component 3. Furthermore, when installing the return lining plate 205, it is only necessary to first slide a return lining plate 205 with a polygonal blind hole 206 and a through hole 208 into one end of the T-shaped slide rail 204, so that the through hole 208 is coaxial with the through hole 207, and then use the bolt 209 and the screw rod to detachably fix it on the mounting steel plate 201, and then slide and connect other return lining plates 205 in turn, and finally put a return lining plate 205 with a polygonal blind hole 206 and a through hole 208 into the mounting steel plate 201. The plate 205 slides into the through hole 207 at the other end of the T-shaped slide rail 204, and is detachably fixedly connected to the mounting steel plate 201 by means of the cooperation of the bolts 209 and the screw rods, thereby completing the fixed connection between the single-row return plate 205 and the mounting steel plate 201. Compared with the existing installation method, fewer bolts 209 and nuts 210 need to be tightened, and no holes need to be punched on the return plate 205 located in the middle position on the T-shaped slide rail 204, thereby ensuring the durability of the return plate 205.
