Detailed Description

In order to make the technical problems, technical solutions and advantageous effects to be solved by the present invention more clearly apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

As shown in fig. 1 to 3, a hammer crusher rotor structure, including fixed disk 1 and a plurality of tups 2 of installing between the fixed disk, the both sides of fixed disk 1 are provided with mounting groove 3, be provided with constant head tank 4 on the mounting groove 3, install connecting block 5 in the mounting groove 4, connecting block 5 is fixed on fixed disk 1, and still be provided with shaft hole 6 on the connecting block 5, install connecting axle 7 between the connecting block 5, the both ends cartridge respectively of connecting axle 7 is in the shaft hole, tup 2 rotates and installs on connecting axle 7.

The hammer head adopts a split type mounting structure, each hammer head is mounted and fixed through the connecting blocks on the fixing discs on the two sides respectively, the fixing discs are provided with mounting grooves, the connecting blocks are mounted in the mounting grooves, then shaft holes are formed in the connecting blocks, the connecting shaft penetrates through the hammer handle through holes of the hammer heads, and the two ends of the connecting shaft are inserted in the shaft holes, so that mounting is realized. When the hammer is installed, the two ends of the connecting shaft are inserted into the shaft holes of the connecting blocks, and then the connecting blocks are installed in the installation grooves to complete fixation.

Wherein, mounting groove 3 is U type groove, the both sides in U type groove are provided with guide way 8, connecting block 5 constitute including guide block 9 and arc fixed plate 10, shaft hole 6 sets up the lower part at guide block 9, the both sides of guide block 9 are provided with the protruding stupefied 11 of direction, guide block 9 cartridge is in U type inslot, the bottom of guide block 9 is the circular arc type, the protruding stupefied 11 cartridge of direction is in guide way 8, arc fixed plate 10 fixes the top at guide block 9, and arc fixed plate 10 on the guide block of fixed disk 1 both sides stacks the setting, and bottom arc fixed plate 10 hugs closely the outer fringe of fixed disk 1 and arranges, install fixing bolt 12 on arc fixed plate 10, fixing bolt 12 fixes on the outer fringe of fixed disk 1.
