The technical scheme of the invention is realized as follows:
the utility model provides a take multiple plastic function's vertical scroll impact breaker, includes crushing room, rotor, the inside crushing chamber that is formed with of crushing chamber, the inner wall department of crushing chamber has the material lining that broken material was piled up, the rotor passes through the rotatable setting of main shaft in the crushing chamber, there is the discharge gate crushing chamber bottom, the crushing chamber top has the branch material room, the inside branch material inner tube that is provided with of branch material chamber, the opening center of branch material inner tube is provided with the bulk cargo dish, the lateral wall top of branch material inner tube be higher than bulk cargo dish top place height, the export of branch material inner tube bottom corresponds with the import of rotor, the outside edge of rotor and the distance between the material lining reduce to 40~150mm, the circumference detachable of rotor be provided with the grinding plate that negotiates, grind the even distribution of grinding plate, leave the rotor throwing mouth between the grinding plate that negotiates, the surface area ratio of grinding plate's side surface area and rotor gyration is 4~7:10.
The top of the side wall of the material separating inner cylinder is higher than the top of the bulk cargo disc by 100-150 mm.
The upper edge and the lower edge of the grinding plate are correspondingly coated on the top surface and the bottom surface of the rotor, and the inner side surface of the grinding plate is fixedly connected with the supporting plate of the rotor through bolts.
The invention has the positive effects that: the side wall of the material distribution inner cylinder is heightened and higher than the height of the bulk cargo tray, so that materials enter from the center and cannot fall into a gap between the material distribution inner cylinder and the material distribution chamber; the grinding plate is installed on the outer side of the rotor, the contact area between the material and the rotor is increased, the distance between the rotor and the material lining is reduced to increase the contact between the rotor and the counterattack material, the impact probability between the counterattack material and the rotor is increased, the shaping of the edges and corners of the material is improved, the grading duty ratio between 0.15 mm and 0.6mm in a finished sand making machine is increased, the machine-made sand grading rationality and fluidity are improved, the grinding plate is detachably connected with the rotor, and the grinding plate can be detached for replacement after being worn.
