Abstract
The utility model discloses a crusher with a drum and a dental plate, which comprises a drum (2) and a dental plate (1), wherein, the drum (2) is connected with the dental plate (1) through a concave-convex key (3); the concave-convex key is of a shape with both ends having large size and the middle part having smaller size, while the key slots of the drum (2) and the dental plate (1) are of a shape with the interior having larger size and the exterior having the smaller size; the complex dovetail mortise connection transmission between the dental plate (1) and the drum (2) is changed to be the simple and modularized combination connection transmission among the dental plate (1), the concave-convex key (3) and the drum (2), so that the crusher has the advantages that the material cost is reduced by reducing the size of the spare parts of the dental plate (1), and the maintenance is convenient through the modular combination way.
Description
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 this version also exists the get the raw materials ready oversize material cost height that causes, dovetail or crushing teeth one of tooth plate to decrease that tooth plate is all to decrease the shortcoming that the inconvenient maintenance, tooth plate axial float, tooth plate and the roller contact stress that cause are concentrated simultaneously.
The utility model content
The purpose of this utility model provides a kind of tooth plate, and the cost of material is low, easy to maintenance, can prevent the tooth plate axial float, reduce the disintegrating machine that tooth plate and roller contact stress are concentrated.
For solving the problems of the technologies described above, a kind of disintegrating machine of the utility model comprises roller and tooth plate, its roller is connected by concavo-convex key with tooth plate, and concavo-convex key is the shape that the two ends size is big, intermediate sizes is little up and down, and roller keyway and tooth plate keyway correspondingly are the shape that size is big in the groove, the notch size is little.
Described a kind of disintegrating machine, its concavo-convex key and the whole keyway that is mated, be made up of jointly roller and tooth plate are any shape in concave shape, I-shaped, V font, double-swallow-tail shape or the U font.
Described any disintegrating machine, the corner of its concavo-convex key is circular arc, and the roller keyway that is mated and the corner of tooth plate keyway are corresponding circular arc.
Described any disintegrating machine is shaped on screwed hole between the two in its roller, tooth plate and the concavo-convex key or the three, and fastening by limit screw.
Since the utility model be with the dovetail tongue-and-groove of tooth plate and roller complexity connect that transmission changes over simply, connection transmission between the tooth plate of module combinationsization, concavo-convex key and the roller three, with limit screw that the three is fastening, and three's cooperation corner changed over circular arc, therefore the utlity model has by dwindling the tooth plate size of getting the raw materials ready and reduce material cost, reach easy to maintenance, fasteningly prevent the tooth plate axial float, reduce the concentrated advantage of contact stress by cooperating the corner to change over circular arc by screw by the module combinations mode
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;
Fig. 3 is the partial front elevation view of the utility model embodiment three;
Fig. 4 is the partial front elevation view of the utility model embodiment four.
Identify among the figure: 1-tooth plate, 2-roller, the concavo-convex key of 3-, 4-limit screw.
The specific embodiment
Embodiment one: as shown in Figure 1, the utility model is earlier tooth plate 1 and roller 2 integral installations to be clipped together, by required size and shape the keyway of tooth plate 1 and roller 2 is processed as the shape that size is big in the groove, the notch size is little with milling machine or wire cutting machine, and by the whole keyway that tooth plate 1 and roller 2 are formed is the concave shape shape that the two ends size is big, intermediate sizes is little up and down, to using milling machine or wire cutting machine concavo-convex key 3 is processed into required concave shape shape therewith, the circular arc of R5 all is processed in the corner that respectively cooperates of key and keyway; The concavo-convex key 3 of concave shape shape is gone in the keyway of roller 2 from axial grafting after, again with the keyway of tooth plate 1 from axially being plugged on the concavo-convex key 3, the concavo-convex key 3 by the concave shape shape is connected transmission together with roller 2 with tooth plate 1 like this; At last, between roller 2, tooth plate 1 and concavo-convex key 3 threes in front, process the M8 screwed hole, get final product the three is fastening with the fluting of M8 awl end limit screw 4.
Embodiment two: as shown in Figure 2, on the basis of embodiment one, only change into I-shaped shape with the concavo-convex key 3 of concave shape shape with by the whole keyway that tooth plate 1 and roller 2 are formed.
Embodiment three: as shown in Figure 3, on the basis of embodiment one, only change into the V glyph shape with the concavo-convex key 3 of concave shape shape with by the whole keyway that tooth plate 1 and roller 2 are formed.
Embodiment four: as shown in Figure 4, on the basis of embodiment one, only change into the double-swallow-tail shape shape with the concavo-convex key 3 of concave shape shape with by the whole keyway that tooth plate 1 and roller 2 are formed.
