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; after the buttress root (3)is plugged into the rectangular groove of the drum (2), a through hole is arranged between the buttress root (3) and the drum (2), and both ends of the through hole are provided with a sunken hole which is larger than the through hole, and a shaft connection tightening component (4) is arranged inside the through hole; the complex dovetail mortise connection transmission between the dental plate (1) and the drum (2) is changed to be the simple connection transmission of the key slot shaft connection tightening element (4), so that the crusher has the advantage that the processing is simple, and the axial jumping of the dental plate (1) can be prevented.

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, after the tooth plate root inserts the roller rectangular channel, between tooth plate root and roller rectangular channel, be shaped on a through hole jointly, the through hole two ends are shaped on the counterbore greater than through hole, the cover dress prevents that the axle class of tooth plate axial float from connecting fastening assembly on the through hole, and its counterbore is used for settling the axle class to connect the fastening assembly two ends, convenient fastening tooth plate and roller, and the flat side down that guarantees tooth plate and roller does not have projection.

Described a kind of disintegrating machine, it is the bolt assembly of being made up of nut, packing ring, bolt that its class connects securing member.

Described a kind of disintegrating machine, it is the Assembly of pin of being made up of split pin, bearing pin with holes that its class connects securing member.

Described a kind of disintegrating machine, it is the pin with split pin hole assembly of being made up of split pin, pin with split pin hole that its class connects securing member.

Described any disintegrating machine, the mating edge angle part between its tooth plate root and the roller is circular arc.

Because the utility model is the dovetail tongue-and-groove with tooth plate and roller complexity to be connected transmission and to change over simple keyway tape spool class and connect the connection transmission of fastening assembly and make the mating part of tooth plate root and roller into circular arc by wedge angle, thus the utlity model has processing simple, can prevent the tooth plate axial float, reduce tooth plate and the concentrated advantage of roller contact stress.

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 the partial left cutaway view of the utility model embodiment one;

Fig. 3 is the partial left cutaway view of the utility model embodiment two;

Fig. 4 is the partial left cutaway view of the utility model embodiment three.

Identify among the figure: the 1-tooth plate, the 2-roller, 3-tooth plate root, 4-axle class connects fastening assembly, 5-bolt assembly, 6-Assembly of pin, 7-pin with split pin hole assembly.

The specific embodiment

Embodiment one: 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; Treating that tooth plate root 3 inserts clamps behind rollers 2 rectangular channels fixingly, processes a through hole jointly between tooth plate root 3 and roller 2 rectangular channels, and the through hole two ends process the counterbore greater than through hole, the bolt assembly 5 that the cover dress is made up of nut, packing ring, bolt on the through hole.

Embodiment two: as Fig. 1, shown in Figure 3, compare with embodiment one, just use the Assembly of pin 6 that is become by split pin, bearing pin with holes to replace bolt assembly 5.

Embodiment three: as Fig. 1, shown in Figure 4, compare with embodiment one, just use the pin with split pin hole assembly 7 that is become by split pin, pin with split pin hole to replace bolt assembly 5.
