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 rectangular shape, and the part of the drum (2), which is matched with the buttress root (3) is of a rectangular groove, and the rectangular groove of the drum (2) is provided with a rectangular through groove, and the buttress root (3) is provided with a groove, and a transmission key (5) part which is matched with the size of the groove is embedded inside the groove, and the other part of the transmission key is installed inside the rectangular through groove of the rectangular groove of the drum (2); the complex dovetail mortise groove connection transmission between the dental plate (1) and the drum (2) is changed to be the simple key slot connection transmission, so that 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, the tooth plate root of its tooth plate is a rectangle, the roller part that cooperates with the tooth plate root correspondingly is rectangular channel, on the roller rectangular channel, be shaped on rectangular through slot, on the tooth plate root, be shaped on groove accordingly, the part of the driving key that adapts with the groove size inlay be fixed on the groove, part is installed in the rectangular through slot of roller rectangular channel in addition.

Described a kind of disintegrating machine, the mating edge angle part between its tooth plate root, roller and the driving key is circular arc.

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

Since the utility model be with the dovetail tongue-and-groove of tooth plate and roller complexity connect transmission change over simple keyway connect transmission, the mating part of tooth plate root, roller and driving key 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;

Fig. 2 is a partial left cutaway view of the present utility model.

Identify among the figure: 1-tooth plate, 2-roller, 3-tooth plate root, 4-limit screw, 5-driving key.

The specific embodiment

As shown in Figure 1 and Figure 2, the utility model is earlier with milling machine the tooth plate root 3 of tooth plate 1 to be processed into rectangle, processes rectangular channel with milling machine accordingly on roller 2, and the circular arc of R5 is processed in the corner that respectively cooperates on the rectangular channel of tooth plate root 3 and roller 2; Processing the corner circular arc with slotting machine at roller 2 rectangular channels of frontal left then is the R3 rectangular through slot, correspondingly processing the corner circular arc with milling machine on the tooth plate root 3 of frontal left is the groove that R3, two ends are semicircle, and processing the corner circular arc with milling machine simultaneously is the driving key 5 that R3, two ends are semicircle, adapt with the groove size; After inlaying driving key 5 on the groove that is fixed on tooth plate root 3, in the whole rectangular through slot and rectangular channel of axially driving key 5 and tooth plate root 3 correspondingly being inserted roller 2 from the front, and keep positive smooth; At last, between the roller 2 in front and tooth plate 1, process the M8 screwed hole, and by M8 fluting awl end limit screw 4 that roller 2 and tooth plate 1 is fastening.

Claims

1, a kind of disintegrating machine, comprise roller (2) and be connected tooth plate (1) on the roller (2), it is characterized in that: the tooth plate root (3) of tooth plate (1) is a rectangle, roller (2) part that cooperates with tooth plate root (3) correspondingly is rectangular channel, on roller (2) rectangular channel, be shaped on rectangular through slot, on tooth plate root (3), be shaped on groove accordingly, the part of the driving key (5) that adapts with the groove size inlay be fixed on the groove, part is installed in the rectangular through slot of roller (2) rectangular channel in addition.

2, a kind of disintegrating machine according to claim 1 is characterized in that: the mating edge angle part between tooth plate root (3), roller (2) and the driving key (5) is circular arc.
