Embodiment Construction

[0041] Hereinafter, while referring to the appended Figure 1 The dustproof structure of the rotary crusher according to the present invention will be described in detail.

[0042] The dust-proof structure involved in this embodiment includes: an acetabular wall support assembly that fixes the acetabular wall; a frame assembly provided with a vertical hole (shaft); and an eccentric shaft sleeve assembly, which includes a The eccentric shaft sleeve, and the main shaft fitted with the eccentric shaft sleeve to rotate and to which the crushing wall core is installed, the dust-proof structure can be suitably applied to the following rotary crusher, which has the The crushing chamber between the rotating crushing walls installed on the crushing wall core is used to crush the structure of the object to be crushed.

[0043] The frame assembly has an annular crushing wall support platform that supports the back side of the eccentrically moving crushing wall core. An oil chamber fill...

Abstract

The invention provides a splitter plate for limiting a rotary breaker and a dustproof structure which can prevent a dustproof seal ring from being worn and reducing the maintenance frequency. The rotary breaker is provided with a structure configured in a way that a breaking chamber for breaking objects to be broken is formed on a mortar wall and between breaking walls (23) installed on a breaking wall core (25) to rotate, at the inner side of an annular breaking wall supporting platform (12) which is on the back of the breaking wall core (25) for supporting eccentric motions, an oil chamber (32) which can be filled with lubricating oil is formed, at the outer side of the breaking wall supporting platform (12), an annular space (33) divided by a dustproof seal ring (15) arranged between a frame assembly (10) and the back of the breaking wall core (25) is arranged. The dustproof seal ring (15) is fixedly arranged and does not rotate relative to the frame assembly (10), thus, even through the breaking walls (23) rotate, the dustproof seal ring does not rotate together, and therefore the dustproof seal ring is prevented from being worn.

Description

technical field [0001] The present invention relates to a rotary crusher for supplying and crushing rough stones between a rotating crushing wall (mantle) and a mortar wall (corner wall), and more particularly to a dustproof structure of the rotary crusher. Background technique [0002] Rotary crushers such as cone crushers and gyratory crushers are machines equipped with a crushing chamber formed by the following members: a funnel-shaped crushing wall fixed to the main shaft performing precession by fasteners, and a socket wall arranged to cover the broken wall. When supplying rough stones to the crushing chamber of the rotary crusher from a hopper provided above the rotary crusher, the rotary crusher crushes the rough stones filled between the crushing wall and the mortar wall into a predetermined particle size and supplies them. [0003] Figure 9 It is a sectional view showing an example of a conventional rotary crusher. [0004] The main shaft is inserted into a hole ...
