Description

Kibbler roll

Technical field

The utility model relates to a kind of construction waste crushing equipment, particularly relates to a kind of kibbler roll.

Background technology

At present; The domestic equipment that is used for construction waste crushing mainly contains jaw crusher, hammer mill, impact breaker, kibbler roll etc.; And jaw crusher is the preferred unit of building waste precrushing; Hammer mill, impact breaker and kibbler roll be fit to be produced a section sand, are used for the building waste second-time breakage of the large-block material that obtains of broken category filter just.Traditional oppositely rolling roller crusher is a smooth roll, adopts the solid roll structure, and there are many irrational defectives in its roll body structure; Little such as roll body and material contact area; The grain shape of producing is inhomogeneous, and needs artificial material after the fragmentation is poured into to carry out the repetition fragmentation between the breaker roll again, and output is not high; Unit ton material power consumption is big, and production efficiency is low.Also such as the roll body diameter hour, breaking strength is limited, and when the roll body diameter was big, roll body weight increased greatly, brought inconvenience to workman's installation and later period maintenance, and workman's installation, maintenance labour intensity improves greatly.

Summary of the invention

The technical problem that the utility model will solve is exactly the deficiency that overcomes above-mentioned prior art, and provides a kind of rational in infrastructure, and production efficiency is high, and crushing effect is good, and the workman installs and the kibbler roll of the labour intensity of later period maintenance but also can reduce.

For solving the problems of the technologies described above, the technical scheme of the utility model is:

A kind of kibbler roll; Comprise frame, be fixedly mounted on the charging aperture of upper rack, the charging aperture below is provided with and is fixedly mounted on relatively turnable breaker roll on the frame, and the breaker roll below is provided with the discharging opening that is fixedly mounted on frame lower; Breaker roll comprises the roll body of split setting and the spindle nose of concentric; Said roll body is the hollow roller that two ends are respectively equipped with stepped hole, and said spindle nose is split type spindle nose, comprise the step axle and be fixedly set on the step axle and with the former of step axle coaxial line; The stepped hole of spindle nose former and said roll body is complementary, and is evenly distributed with a plurality of crushing teeths along the roll body outer circumference surface.

Said spindle nose former has one at least, and the spindle nose former is weldingly fixed on the step axle.

Said crushing teeth and roll body are conjoined structure or divide body structure.

Said crushing teeth and roll body are that the roll body outer circumference surface is provided with groove when dividing body structure, and crushing teeth tooth root portion and groove are complementary, and are welded on the roll body outer circumference surface.

Said crushing teeth cross section is choosing any one kind of them in subtriangular, approximate rectangular, approximate trapezoid, the rounded.

Said roll body is that interference fit is connected with spindle nose.

Said roll body is fixedly connected with the spindle nose welding.

Said roll body adopts securing member to be connected with spindle nose in the outer face of mating surface.

The beneficial effect of the utility model technical scheme is:

1, on the structure, the utility model crusher in crushing roller is evenly distributed with a plurality of crushing teeths along outer circumference surface, has strengthened material and roll body surface contact area; Better broken material, the material particles after fragmentation is even, and crushing effect is good; Quality is high, and the material after broken does not need to pass through the repetition fragmentation again; Output is high, and unit ton material power consumption is little, and production efficiency is high.

2, on the structure; The utility model crusher in crushing roller adopts hollow roll body and spindle nose split assembly structure; Under the situation that the roll body diameter increases; Compare with traditional smooth roll (solid roll structure) and to have alleviated breaker roll weight greatly, be convenient to that the workman installs and the maintenance work in later stage, greatly reduce the labour intensity of workman in the installation, maintenance process.

3, on the structure, the utility model crusher in crushing roll shaft head adopts former and step axle split Welding Structure, is applicable to the bigger situation of roll body spindle nose vary in diameter, has not only reduced processing charges, has also reduced the waste of material; And when barrel length was longer, the breaker roll spindle nose adopted a plurality of formers and step axle split Welding Structure, can guarantee that breaker roll can not occur bending and deformation in long-time use, has improved the service life of breaker roll.

4, on the structure, the preferred roll body of the utility model crusher in crushing roller adopts securing member to be connected with spindle nose in the outer face of mating surface, is convenient to the workman and dismantles maintenance or replacing, has reduced user's use cost.
