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 paired smooth roll, and is 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 comprises frame, is fixedly mounted on the charging aperture of upper rack, and the charging aperture below is provided with and is fixedly mounted on relatively turnable breaker roll on the frame; The breaker roll below is provided with the discharging opening that is fixedly mounted on frame lower; Breaker roll between said charging aperture and the discharging opening is two pairs of breaker rolls that are provided with up and down, and following paired breaker roll level interval is provided with the stock guide that is fixedly mounted on central rack between the breaker roll up and down in pairs less than top paired breaker roll level interval; Said breaker roll comprises roll body and the spindle nose that split is provided with; Roll body is the hollow roller that two ends are respectively equipped with stepped hole, and coupling is equipped with the step spindle nose in the stepped hole, and the spindle nose outside vertically is provided with the setting that tapers off of two step surfaces and diameter; Roll body is provided with a plurality of tooth bars along outer circumference surface, and tooth bar direction and roll body axis direction have certain angle.

Said tooth bar and roll body are conjoined structure or divide body structure.

Said tooth bar and roll body are that tooth bar evenly is welded on the roll body outer circumference surface when dividing body structure.

Said tooth bar 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, be arranged with two pairs of breaker rolls on the utility model disintegrating machine, breaker roll roll body outer circumference surface is provided with the broken tooth bar in a certain angle with the roll body axis on the one hand, has strengthened material and roll body surface contact area; Better broken material, the material particles after fragmentation is even, and crushing effect is good, and quality is high; And, two pairs of breaker rolls are set up and down, following paired breaker roll level interval is further dwindled, the material after last paired breaker roll fragmentation; Through paired breaker roll second-time breakage down, can once produce more short grained material, production efficiency improves; Material particles after the fragmentation is even, and crushing effect is good, and quality 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 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.

4, on the structure; The utility model crusher in crushing roller roll body outer circumference surface is provided with the broken tooth bar in a certain angle with the roll body axis; With respect to the broken tooth bar along the roll body axis direction, this breaker roll structure is moved more steady at work, is particularly suited for the running under the high speed operation state; Mechanical performance is dominant, and also helps further to enhance productivity.
