Abstract

The utility model discloses a double-geared roller crusher. Two kinds of toothed plates are installed on two gear rollers, broken teeth of one toothed plate are arranged in an axial and left spiral mode, broken teeth of the other toothed plate are arranged in an axial and right spiral mode, and in the process of installing, the two toothed plates are strictly installed at intervals. The surrounds of one toothed plate are the other toothed plate either in the axial direction or in the circumferential direction, rhombuses are formed in the gear rollers through the broken teeth of the toothed plates, the distances between the broken teeth are not even any more from the circumference of the gear rollers, some distances become small, some distances become large, but the mean distance is the same as the original mean distance. Due to the fact that some tooth distances on the circumference become large, larger materials can be clamped into the crusher. Due to the fact that the mean tooth distance is not changed, the average discharging granularity is not changed basically. Therefore, the crushing capacity of the crusher is enhanced compared with the breaking capacity of an original crusher.

Description

A kind of double-geared roller crusher

Technical field

The utility model relates to a kind of double-geared roller crusher, belongs to the mining machinery field.

Background technology

Existing double-geared roller crusher, a kind of tooth plate of general installation on two discaling rolls, the tooth on its tooth plate is often arranged in a straight line vertically, from the crushing teeth of axially looking, at circumference, is uniformly distributed; Perhaps the tooth on tooth plate is helical arrangement vertically, but, because same tooth plate rotation direction is identical, from the crushing teeth of axially looking, also is uniformly distributed on circumference.

Centre-to-centre spacing and the distance dependent of crushing teeth on the discaling roll circumference of raw meal particle size that disintegrating machine can clamp size and two discaling rolls, namely two discaling roll centre-to-centre spacing are larger, can clamp into raw meal particle size larger; Simultaneously the distance of crushing teeth on the discaling roll circumference is larger, can clamp into raw meal particle size also larger.General double-geared roller crusher due to centre-to-centre spacing and crushing teeth the distance on circumference all definite, so it is also substantially definite that it can clamp into the granularity of material, its ratio of reduction only has 3～5 times, otherwise material just can not normally clamp and skid on discaling roll, thereby affect output, increase wearing and tearing and cause that even putty can't normally use disintegrating machine, this has limited the use of toothed roll crusher to a great extent.

The utility model content

For above-mentioned deficiency, the utility model provides a kind of and increases feed size and do not change discharging-material size, can increase the double-geared roller crusher of the ratio of reduction.

in order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of double-geared roller crusher, two kinds of tooth plates are installed on two discaling rolls, wherein a kind of crushing teeth of tooth plate is left-handed arrangement vertically, the crushing teeth of another kind of tooth plate is vertically dextrorotation and arranges, and install at two kinds of strict intervals of tooth plate when mounted, namely no matter axially or circumferencial direction, a kind of surrounding of tooth plate is another kind of tooth plate, the crushing teeth of tooth plate will form rhombus one by one on discaling roll like this, no longer even from the distance of the broken between cog of discaling roll circumference, but some distances diminish, some distances increase, but average distance is with original the same., because tooth pitch on the part circumference increases, make disintegrating machine can clamp into larger material, and because average tooth pitch is constant, so average discharging-material size is substantially constant, thereby the ratio of reduction of disintegrating machine increased more originally.

Description of drawings

Fig. 1 is tooth plate installation diagram on common double rod-toothed crusher discaling roll.

Fig. 2 is that on common double rod-toothed crusher discaling roll circumference, crushing teeth distributes and clamps into the material schematic diagram.

Fig. 3 is tooth plate installation diagram on the utility model double-geared roller crusher discaling roll.

Fig. 4 is that on the utility model double-geared roller crusher discaling roll circumference, the tooth crushing teeth distributes and clamps into the material schematic diagram.

Wherein, Reference numeral: 1 for common crusher toothed plate, 1a be common tooth plate crushing teeth, 2 for dextrorotation tooth plate, 2a be the dextrorotation tooth plate crushing teeth, 3 for left-handed tooth plate, 3a be the crushing teeth of left-handed tooth plate.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As depicted in figs. 1 and 2, common double-geared roller crusher, two discaling rolls are installed a kind of tooth plate (1), no matter the crushing teeth (1a) on tooth plate (1) is arranged in a straight line or helical arrangement vertically, from seeing that axially crushing teeth (1a) all is uniformly distributed on circumference, because the centre-to-centre spacing of two discaling rolls and the distance of crushing teeth (1a) on circumference are determined, thus disintegrating machine can clamp into raw meal particle size also determine, disintegrating machine only has the ratio of reduction of 3～5 times usually.

as shown in Figure 3 and Figure 4, a kind of double-geared roller crusher of the utility model, two discaling rolls are equipped with dextrorotation tooth plate (2) and (3) two kinds of tooth plates of left-handed tooth plate, crushing teeth (2a) on tooth plate (2) is dextrorotation and arranges, crushing teeth (3a) on tooth plate (3) is left-handed arrangement, and install at two kinds of strict intervals of tooth plate when mounted, namely no matter axially or circumferencial direction, the surrounding of tooth plate (2) is tooth plate (3), the surrounding of same tooth plate (3) is tooth plate (2), the crushing teeth of tooth plate will form rhombus one by one on discaling roll like this, no longer even from the distance of the broken between cog of discaling roll circumference, but some distances diminish, some distances increase, but average distance is with original the same., because tooth pitch on the part circumference increases, make disintegrating machine can clamp into larger material, and because average tooth pitch is constant, so average discharging-material size is substantially constant, thereby the ratio of reduction of disintegrating machine increased more originally.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.

Claims

1. double-geared roller crusher, it is characterized in that: two kinds of tooth plates are installed on two discaling rolls, wherein a kind of crushing teeth of tooth plate is left-handed arrangement vertically, the crushing teeth of another kind of tooth plate is vertically dextrorotation and arranges, and install at two kinds of strict intervals of tooth plate when mounted, namely no matter axially or circumferencial direction, a kind of surrounding of tooth plate is another kind of tooth plate, the crushing teeth of tooth plate will form rhombus one by one on discaling roll like this, no longer even from the distance of the broken between cog of discaling roll circumference, but some distances diminish, some distances increase, but average distance is with original the same.
