Abstract
The utility model discloses a kind of can the disintegrating machine working roll of radial mounting or dismounting tooth plate fast, comprise tooth plate, insert, roller, set bolt, lock washer, locking swivel nut.Wherein tooth plate plate face is circular arc, and tooth plate central bottom is special-shaped boss, and special-shaped boss both sides are two parallel inclined-planes, and the following of special-shaped boss is circular arc; End face and the bottom surface of insert are circular arc, insert is welded on circumferentially being evenly distributed of roller, tooth plate radially loads between two adjacent inserts above roller, two parallel-slopes on the special-shaped boss of tooth plate central bottom are used for contacting with the profiled slot that roller is formed between two inserts, the lower arc surface of special-shaped boss and roller close contact, interconnected by set bolt and locking swivel nut and roller, in order to prevent that loosening set bolt is also provided with lock washer, final realization radially fast can install and remove tooth plate.
Description
Technical field
The utility model relates to a kind of disintegrating machine working roll, especially a kind of can the disintegrating machine working roll of radial mounting or dismounting tooth plate fast.
Background technology
The work roller structure of the kibbler roll used in the market is primarily of tooth plate, dovetail and roller composition, dove-tail form boss in the middle of tooth plate, dovetail is distributed on roller and forms dove-tail form groove, tooth plate inserts between two adjacent dovetails from the end face of roller when installing vertically, between tooth plate and dovetail reserved certain gap (being used for panel is installed), by percussion hammer, panel is hit wedging in gap, cause reserving the position of installing percussion hammer, require very high to space for maintenance, in use panel also can get rusty, dismantle also very difficult, tooth plate installation and removal are wasted time and energy, inefficiency.
Utility model content
For above-mentioned technical problem, the utility model object is to provide a kind of reasonable in design, and structure is simple, and reliable, space for maintenance is little, and user radial direction can install and remove the disintegrating machine working roll of tooth plate fast.
In order to achieve the above object, disintegrating machine working roll of the present utility model, comprises tooth plate, insert, set bolt, lock washer, locking swivel nut, roller.Wherein tooth plate plate face is circular arc, and central bottom is special-shaped boss, and the both sides of special-shaped boss are two parallel inclined-planes; End face and the bottom surface of insert are circular arc, and what insert was welded on roller is circumferentially uniform distribution, and between each insert, define a profiled slot, two inclined-planes forming profiled slot between adjacent two inserts are parallel to each other; Tooth plate radially loads between two adjacent inserts when installing above roller, two parallel-slopes on the special-shaped boss of tooth plate central bottom are used for contacting with the profiled slot that roller is formed between two inserts, the lower arc surface of special-shaped boss and roller close contact, interconnected, in order to prevent that loosening set bolt is also provided with lock washer by set bolt and locking swivel nut and roller.
The utility model disintegrating machine working roll operation principle is: after material enters disintegrating machine, and between a pair mutual working roll rotated, carry out occlusion broken, after broken, material is discharged from bottom.In shattering process, the hard material of bulk is delivered on tooth plate to a part of vertical direction along profile of tooth acting surface of the active force of tooth plate, is delivered on roller by the acting surface of tooth plate and roller; Part turning torque is delivered in insert by the contact surface of tooth plate and insert.
The utility model disintegrating machine working roll, structure is simple, reliable and stable.During installation, tooth plate loads along roller radial direction, due to two on the special-shaped boss of tooth plate central bottom between parallel-slope with insert for face contacts, comparatively noticeable effort can be born; The lower arc surface of the special-shaped boss of tooth plate central bottom is that face contacts with the outer fenestra of roller, in conjunction with quite firm; As long as such set bolt overcomes the centrifugal force of tooth plate itself, by just passable for tooth plate tension, set bolt does not bear shearing force substantially, only bears pulling force, because working roll rotating speed is not high, tooth plate weight does not weigh, centrifugal force is very little, so set bolt phenomenon of rupture can not occur, again because there is lock washer, set bolt also can not loosen, safe and reliable.After tooth plate uses wearing and tearing for a long time, unclamp set bolt with specific purpose tool, set bolt is taken out, just fast tooth plate can be taken out along roller radial direction and change, not only convenient and swift but also do not take how many spaces.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, Figure 2, Figure 3, Figure 4.
The utility model comprises tooth plate (1), insert (2), set bolt (3), lock washer (4), locking swivel nut (5), roller (6).Wherein tooth plate (1) plate face is circular arc, and central bottom is special-shaped boss, and the both sides of special-shaped boss are two parallel inclined-plane one (1a), inclined-planes two (2a), end face and the bottom surface of insert (2) are circular arc, and insert (2) is welded on circumferentially being evenly distributed of roller (6), define a profiled slot between each insert (2), when tooth plate (1) is installed, it is radially put between two adjacent inserts (2) above roller (6), two inclined-planes (1a) of the special-shaped boss of tooth plate (1) central bottom, (2a) contact with two parallel-slopes of the profiled slot formed between each insert (2), the lower arc surface (3a) of the special-shaped boss of tooth plate (1) central bottom and roller (6) periphery close contact, interconnected with roller (6) by set bolt (3) and locking swivel nut (5), in order to prevent that loosening set bolt (3) is also provided with lock washer (4).When needs dismounting tooth plate (1), unclamp set bolt (3) with specific purpose tool and taken out by set bolt (3), just can have been taken out along roller radial direction by tooth plate (1) fast, this operating process is easy and light, does not take very large space for maintenance again.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
