[0026] Among them, the connecting block 104 is located in the placement groove 102, and the connecting block 104 has a socket 108; the working protruding teeth 105 are fixedly connected to the connecting block 104 and are located on the side of the connecting block 104; the tensioning screw 106 is slidingly connected to the support plate 101 and passes through the support plate 101 and the socket 108; the two nuts 107 are respectively threadedly connected to the tensioning screw 106 and are located on both sides of the tensioning screw 106. During use, the support plate 101 is installed on the roller shaft of the tooth roller crusher, and the tooth roller crusher drives the roller shaft to rotate, and the material is crushed by the rotation of the working convex teeth 105. The working convex teeth 105 are made of wear-resistant alloy material, and the wear-resistant alloy material can be selected from high-manganese alloy wear-resistant material, so that the working convex teeth 105 have good wear resistance. When a certain working convex tooth 105 is damaged after long-term use, the staff can remove the two nuts 107 on the tension screw 106, and then remove the tension screw 106 from the connecting block 104 and the support plate 101, and then remove the connecting block 104 and the working The tooth 105 is removed from the support plate 101, and then the staff can take out a new working tooth 105, insert the connecting block 104 on the working tooth 105 into the placement groove 102 on the support plate 101, and then insert the tension screw 106 into the support plate 101 and pass it through the insertion hole 108, and then tighten the two nuts 107 at both ends of the tension screw 106 to complete the replacement of the working tooth 105; in this way, after a certain working tooth 105 is damaged, the damaged working tooth 105 can be replaced separately, so that there is no need to replace the entire crusher tooth plate, which reduces the replacement cost.

The magnet 110 adsorbs the iron block 109 to prevent the working tooth 105 from moving when the tension screw 106 is inserted. Then the tension screw 106 is inserted into the support plate 101 and passed through the insertion hole 108, and then the two nuts 107 are tightened at both ends of the tension screw 106 to complete the replacement of the working tooth 105. In this way, after a certain working tooth 105 is damaged, the damaged working tooth 105 can be replaced separately, thereby reducing the replacement cost.
