Abstract

The utility model discloses a crusher with a drum and a dental plate, which comprises a drum (2) and a dental plate (1) which is connected with the drum (2), wherein, a buttress root (3) of the dental plate (1) is of a wedged shape, and the part of the drum (2), which is matched with the buttress root (3) is of a wedged groove; for a dovetail-shaped groove of the buttress root (3) and the drum (2) is changed to be a semi-dovetail wedged shape, the crusher has the advantages of simple processing.

Description

Disintegrating machine

Technical field

The utility model relates to the disintegrating machine that application roller is milled, and particularly relates to a kind of disintegrating machine with roller and tooth plate.

Background technology

Current, many disintegrating machines adopt screws that tooth plate is fixed on version on the roller, and this structure is easy to cause the screw wearing and tearing or loosens behind the long-time strenuous vibration of experience, tooth plate is come off, and has a strong impact on, threatens and produce and safety.For addressing the above problem, the applying date is to be that the Chinese utility model patent that October 20, the patent No. in 2004 are ZL03249349.5 discloses a kind of disintegrating machine roller tooth plate July 2, Granted publication day in 2003, it is provided with dovetail in arc plate body bottom surface, dovetail is contained in the dovetail groove that matches with it on the roller body, has fixation, can not wear and tear advantage easy for installation; But the shortcoming that this version also exists processed complex, tooth plate axial float, tooth plate and roller contact stress to concentrate simultaneously.

The utility model content

The purpose of this utility model provides a kind of process simply, can prevent tooth plate axial float, reduction tooth plate and the concentrated disintegrating machine of roller contact stress.

For solving the problems of the technologies described above, a kind of disintegrating machine of the utility model comprises roller and the tooth plate that is connected on the roller, and the tooth plate root of its tooth plate is a wedge shape, and the roller part that cooperates with the tooth plate root correspondingly is wedge-shaped slot.

Described disintegrating machine, the root of its tooth plate root are circular arc.

Described disintegrating machine, the edge angle of its tooth plate root partly are circular arc.

Described any disintegrating machine, the part that its roller cooperates with the root and the edge angle of tooth plate root is corresponding circular arc.

Described any disintegrating machine, it is shaped on screwed hole between the roller in front and tooth plate, and by limit screw that roller and tooth plate is fastening.

Because the wedge-type shape that the utility model is tooth plate root and the roller groove with a dovetail makes half dovetail into, the mating part of tooth plate root and roller is made into circular arc and set up limit screw between tooth plate and roller by wedge angle fastening, thereby the utlity model has processing simple, can prevent the tooth plate axial float, reduce the advantage that tooth plate and roller contact stress are concentrated.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is a partial front elevation view of the present utility model.

Identify among the figure: 1-tooth plate, 2-roller, 3-tooth plate root, 4-limit screw.

The specific embodiment

As shown in Figure 1, the utility model be earlier with wire cutting machine with the tooth plate root 3 of tooth plate 1 be processed into wedge-type shape, the circular arc that the root and the edge angle of tooth plate root 3 is processed into R4, the part that roller 2 is cooperated with tooth plate root 3 be processed into corresponding wedge shape arc groove, then the tooth plate root 3 of tooth plate 1 axially inserted from the front in the wedge shape arc groove of roller 2, and keep positive smooth, between the tooth plate root 3 in front and roller 2, process at last the screw of M10, hold limit screw 4 fastening tooth plates 1 and roller 2 to get final product with the fluting awl of M10.

Claims

1, a kind of disintegrating machine comprises roller (2) and is connected tooth plate (1) on the roller (2) that it is characterized in that: the tooth plate root (3) of tooth plate (1) is wedge shape, and the roller (2) that cooperates with tooth plate root (3) part correspondingly is a wedge-shaped slot.

2, disintegrating machine according to claim 1 is characterized in that: the root of tooth plate root (3) is a circular arc.

3, disintegrating machine according to claim 1 is characterized in that: the edge angle of tooth plate root (3) partly is circular arc.

4, according to claim 2 or 3 described any disintegrating machines, it is characterized in that: roller (2) is corresponding circular arc with the part that the root and the edge angle of tooth plate root (3) cooperate.

5, according to claim 1,2 or 3 described any disintegrating machines, it is characterized in that: between the roller (2) in front and tooth plate (1), be shaped on screwed hole, and by limit screw (4) that roller (2) and tooth plate (1) is fastening.

6, a kind of disintegrating machine according to claim 4 is characterized in that: between the roller (2) in front and tooth plate (1), be shaped on screwed hole, and by limit screw (4) that roller (2) and tooth plate (1) is fastening.
