DETAILED DESCRIPTION

[0025] The following is a specific embodiment of the utility model and further describes the technical scheme of the utility model in combination with the drawings.

[0026] As Figures 1-8 shown, a hammer type pulper main shaft, it includes main shaft body 1, a plurality of main shaft spacer disc 13, a plurality of hammer head assembly 2, the main shaft spacer disc 13 is set on the main shaft body 1, its characterized in that,

[0027] The first hole is provided with a second hole on one side of the first hole, and each hammer head assembly 2 is installed on the first hole of the main shaft spacer disc 13, and the other end of each hammer head assembly 2 is installed on the second hole of the adjacent main shaft spacer disc 13, so as to form a spiral distribution arrangement of hammer head assembly 2;

[0028] The adjacent main shaft spacer disc 13 is sleeved with a main shaft spacer sleeve 15;

[0029] The left end of the main shaft body 1 is sleeved with a water throwing disc 11, and one side of the water throwing disc 11 has a left fixed ring 12 which is threadedly connected with the main shaft spacer sleeve 15;

[0030] The right end of the main shaft body 1 has a stepped ring 161 to prevent the main shaft spacer sleeve 15 from slipping off and a right fixed ring 16 to fix the stepped ring 161.

[0031] Further, the hammer head assembly 2 comprises a hammer head pin shaft 22, a hammer head 21, a hammer head spacer sleeve 26 and a hammer head rotating seat 23. The hammer head pin shaft 22 has a pin hole end 24 at one end which penetrates through the second hole, and a clamping head 28 at the other end. The pin hole end 24 is provided with a limiting pin 25 which is fixed therein. The hammer head pin shaft 22 has the hammer head rotating seat 23 in the middle, and the hammer head 21 is rotatably connected to the hammer head rotating seat 23. The hammer head rotating seat 23 is sleeved with the hammer head spacer sleeve 26 at one end close to the clamping head 28. The hammer head spacer sleeve 26 has a certain spacing with the clamping head 28 and forms a clamping groove 27 which clamps the first hole. The hammer head assembly 2 is installed by penetrating the pin hole end 24 of the hammer head pin shaft 22 through the second hole and being fixed by the limiting pin 25, and the other end is fixed by clamping the first hole through the clamping groove 27. The adjacent spacer discs 13 are installed in turn with the hammer head assembly 2 in staggered spiral manner, forming four rows of hammer head assemblies 2 in spiral arrangement. Meanwhile, the hammer head 21 can rotate on the hammer head rotating seat 23, and when the hammer head 21 contacts with difficult-to-crush or large block materials, the hammer head 21 can rotate to allow the materials to pass through.
