Abstract

The utility model discloses a crusher provided with a drum and a dental plate. The crusher comprises the drum (2) and the dental plate (1) connected with the drum (2); the dental plate bottom (3) of the dental plate (1) is rectangular; part of the drum (2) matched with the dental plate bottom (3) is a rectangular groove correspondingly; rectangular slots which mutually correspond are formed on the dental plate bottom (3) and the rectangular groove of the drum (2) respectively; and rectangular long keys (5) are arranged in the rectangular slots on the dental plate bottom (3) and the rectangular groove of the drum (2). As the complicated dovetail mortice transmission of the dental plate (1) and the drum (2) is changed into the simple keying slot transmission, 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 tooth plate root and roller rectangular channel, respectively be shaped on rectangular through slot in correspondence with each other, the long key of rectangle is installed in the rectangular through slot of tooth plate root and roller rectangular channel jointly.

Described disintegrating machine, the long key length of its rectangle is not more than the width of tooth plate root or roller.

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

Described any disintegrating machine, it is between the roller and tooth plate in front, be shaped on screwed hole between the long key of the rectangle in front and roller or tooth plate root, and fastening by limit screw.

Described any disintegrating machine is shaped on screwed hole between the long key three of its roller in the front, tooth plate root and rectangle jointly, and fastening by limit screw.

Because the utility model is the dovetail tongue-and-groove of tooth plate and roller complexity to be connected transmission change over that simple keyway connects transmission, to make the mating part of tooth plate root, roller and the long key of rectangle into to set up limit screw between circular arc and the two or the three in the long key of tooth plate, roller and rectangle by wedge angle fastening, thus the utlity model has processing simple, can prevent tooth plate axial float, reduction 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 the partial front elevation view of the utility model embodiment one;

Fig. 2 is the partial front elevation view of the utility model embodiment two.

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

The specific embodiment

Embodiment one, and as shown in Figure 1, 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; Respectively processing the corner circular arc with slotting machine in the relevant position of roller 2 rectangular channels of frontal left and tooth plate root 3 then is the R3 rectangular through slot, and processing the corner circular arc with milling machine simultaneously is the long key 5 of rectangle that R3, length are less than about tooth plate root 3 width or roller 2 width; At last, the tooth plate root 3 of tooth plate 1 inserted in the rectangular channel of rollers 2, axially insert the long key 5 of rectangle in the rectangular through slot of tooth plate root 3 and roller 2 from the front, and maintenance flat side down, between the roller 2 and tooth plate 1 in front, be shaped on the M8 screwed hole between the positive long key 5 of rectangle and the roller 2, and hold limit screw 4 that roller 2 and tooth plate 1, the long key 5 of rectangle and roller 2 is fastening by M8 fluting awl.

Embodiment two: as shown in Figure 2, present embodiment and embodiment one are basic identical, only have any different on the Working position of screwed hole, present embodiment is shaped on the M8 screwed hole jointly between long key 5 threes of roller 2, tooth plate root 3 and the rectangle in front, and by M8 fluting awl end limit screw 4 that the three is fastening.
