Abstract

The utility model relates to a novel rotor block used for impact hammer crushers. A set of rotary hummer disks are connected in series by a square shaft in turn, each of the hammer disk is processed with a square hole in the center, and the periphery of the hammer disk is uniformly distributed with concave grooves. The adjacent hammer disks are orderly threaded by the square shaft through a way that the centerlines of the concave grooves deflect for a definite angle, and the hammer heads position and rotate in the space formed by the concave grooves the side faces of the hammer disks. The hammer heads are arrayed in gapless distribution along the axial direction of the rotor block so as to reduce the non-crushing zones between materials and the hammer heads, raise work efficiency and increase the crushing yield of the complete machine.

Description

Rotor of beater type crushing machine

The utility model relates to mine disintegrating machine equipment; Be particularly related to the improvement of beater type crusher rotor body structure.

According to West Germany O﹠K(Orenstein ﹠ Koppel) company's MAMMUT CRUSHEE beater type disintegrating machine data of producing; Its rotor block structure (accompanying drawing 3) hammer dish is discoid.Tup all is placed in hammer plate side, around the revolution of hammer axle.Tup is isolated by every hammer dish on rotor block is axial.In the rotary course, the space that the thickness of hammer dish causes becomes " dead angle " of tup broken material.

The purpose of this utility model is to manage to reduce tup at axial relative gap, increases the probability of tup broken material, to improve complete machine broken material effect.

The utility model design: be the rotary hammer dish of square shaft series connection in the rotor block, by the original discoid structure that there are square hole, peripheral uniform concave moon groove in central authorities that is transformed into, square shaft was gone here and there successively, the intertwining certain angle of opening of adjacent hammer.The space that tup places hammer dish side, concave moon groove to form is turned round.Axial along rotor block, tup forms overall length, does not axially have a gap arranged distribution.Increase the probability of tup broken material.

Provide embodiment of the present utility model below in conjunction with accompanying drawing.

The utility model embodiment: earlier with steel plate be prefabricated into central authorities square hole (2) is arranged, along the uniform hammer dish (1) (accompanying drawing 1) of peripheral trisection for the rotating concave moon groove of tup (3), 3 uniform hammer axle locating holes (4) are arranged on hammer dish (1).Concave moon groove (3) arc radius R is slightly larger than the radius r of tup revolution circular arc.During assembling, (accompanying drawing 2) every adjacent two hammer dishes (1) select for 60 ° successively along the deflection of concave moon groove center line, and square shaft (7) penetrates along square hole (2) order of each hammer dish, and location hammer axle (5) feeds along each hammer axle locating hole (4).Tup (6) around location hammer axle (5) make an arc turn round in hammer dish (1) side, place, space that concave moon groove forms.Guarantee that tup (6) rotation is good.This example is inserted in discoid hammer dish as the side hammer dish again at the two ends of square shaft (7), and fixing with tight ring, after the termination installs double row self aligning spherical roller bearing, is installed on the complete machine.

The utility model effect: owing to reduce the non-broken material district of tup and material, make material obtain sufficient fragmentation along rotor axial in the disintegrating machine chamber, the operating efficiency of tup improves, and the crushing of complete machine increases.

Claims

1, a kind of usefulness one square shaft one group of hammer dish of connecting, tup turns round beater type crusher rotor body in hammer dish side direction around location hammer axle, it is characterized in that: each hammer dish (1) has square hole (2) for central authorities, periphery is uniform concave moon groove (3), adjacent hammer dish (1) seals in square shaft (7) after with concave moon groove (3) center line deflection certain angle successively, tup (6) turns round in hammer dish (1) side around location hammer axle (5), the space that concave moon groove (3) forms.

2, rotor block according to claim 1 is characterized in that concave moon groove (3) is uniform along the peripheral trisection of hammer dish (1), and the arc radius of concave moon groove (3) is greater than the radius of the revolution circular arc of tup (6).
