Abstract
The utility model discloses a kind of cracker teeth roller of split blade type roller skin, comprise roller core and multiple roller skin, described roller core is polygonal column for installing the active section of roller skin, described roller skin is mounted by means of bolts on the outer surface of polygonal column and forms columned discaling roll, described roller skin is cast by structural alloy steel and is formed, and periphery is provided with multiple roller tooth, on the working face of this roller tooth, heap is welded with wear-resistant alloy layer.The utility model roller core intensity is high, and roller skin is changed convenient, only need pull down the roller skin of serious wear, decrease maintenance time, improve productivity ratio and stock utilization during replacing.
Description
Technical field
The utility model relates to a kind of split blade type roller skin of toothed roll crusher, belongs to the core component of toothed roll crusher.
Background technology
Cement industry toothed roll crusher is mainly used in the auxiliary material materials such as broken clay, shale and siltstone, the roller skin of conventional tooth kibbler roll is monoblock type, cast in one piece amount is large, roller skin is connected by adopting conical surface interference with roller core, whole roller need be pulled down when changing after roller shelling damages, workload is large, and maintenance time is long.Existing split blade type roller skin monolithic casting amount is little, lightweight, only need pull down the roller skin of serious wear when safeguarding and change, and it is convenient to change, and maintenance time is short, and efficiency is high.
Summary of the invention
For the defect existed in prior art and technical problem, the utility model provides a kind of cracker teeth roller changing split blade type roller skin easily.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of cracker teeth roller of split blade type roller skin, comprise roller core and multiple roller skin, described roller core is polygonal column for installing the active section of roller skin, described roller skin is mounted by means of bolts on the outer surface of polygonal column and forms columned discaling roll, described roller skin is cast by structural alloy steel and is formed, and periphery is provided with multiple roller tooth, and on the working face of this roller tooth, heap is welded with wear-resistant alloy layer.
As preferably, described roller core active section is hexagonal cylindrical.
As preferably, described roller skin is along roller core shaft to being divided into multiple independently roller skin zones part.
As preferably, the upper correspondence of described polygonal column each is distributed with independent rollers skin zone part.
Beneficial effect: relative to prior art, the utility model has the following advantages: roller core intensity is high, and roller skin is changed convenient, only need pull down the roller skin of serious wear, decrease maintenance time, improve productivity ratio and stock utilization during replacing.
Accompanying drawing explanation
Fig. 1 is the structural representation of cracker teeth roller described in the utility model;
Fig. 2 is the left view of Fig. 1.
In figure, roller core 1, roller skin 2, bolt 3, roller tooth 4, wear-resistant alloy layer 5.
Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, the utility model is described in further detail.
As illustrated in fig. 1 and 2, the cracker teeth roller of the utility model split blade type roller skin, comprise roller core and multiple roller skin, described roller core is polygonal column for installing the active section of roller skin, described roller skin is mounted by means of bolts on the outer surface of polygonal column and forms columned discaling roll, described roller skin is cast by structural alloy steel and is formed, and periphery is provided with multiple roller tooth, and on the working face of this roller tooth, heap is welded with wear-resistant alloy layer.Designing points of the present utility model is: roller skin is divided into several pieces along the circumferencial direction of roller and axial direction, and circumferencial direction adopts decile, and axial direction chooses suitable burst number according to roller length and structure, makes roller skin structure consistent size as far as possible.All roller skins are bolted on roller core.
In use procedure, roller skin can be subject to the wearing and tearing of material, but the degree of wear at each position of roller skin may be inconsistent, when wherein certain block roller skin serious wear consequently cannot meet instructions for use, only need unload attachment bolt, this roller skin is pulled down, change new roller skin, then fix with bolt.Renewal process is without the need to dismantling the miscellaneous part of roller, and monolithic roller skin is lightweight, and therefore workload is little, and consuming time few, efficiency is high.
