Description
Technical field
The utility model belongs to discarded object recovery technology field, relates to the broken reclaimer of a kind of discarded object, specifically is a kind ofly big solid waste to be broken into fritter, the crusher cutter that is beneficial to recycle.
Background technology
Country advocate energetically with the recycling background of support resource under, people have recognized the importance of resource circulation utilization more and more fully, so produced the industry such as large-sized solid discarded object recyclings such as timber, rubber and plastic, junked tires.
In this industry the inside, disintegrating machine is a most important equipment, and crusher cutter then is the core component of disintegrating machine.Usually the crusher cutter that adopts in the industry generally all is solid tool or alloy welding deposit cutter, this cutter hardness generally all is no more than HRC60, wearing and tearing are than very fast in the course of the work, life-span is shorter, so must often change cutter or repair cutter, and change or must take parts such as body, bearing, main shaft apart when repairing cutter, both wasted time and energy, influence production efficiency again, increase production cost.This phenomenon is seriously restricting the development of industry, is ubiquity and the bottleneck problem being badly in need of solving in the industry.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art part, thereby a kind of crusher cutter is provided, and the cutting edge contact-making surface of this cutter is little, the cutting efficiency height, and fast changeable, easy to maintenance, long service life.
The technical scheme that provides according to the utility model, described crusher cutter comprises body, broken cutter, cutter pawl and trip bolt, body is a regular polygon, every limit offers detent, the back of broken cutter and cutter pawl is provided with and the corresponding positioning boss of detent shape, positioning boss is assemblied in the detent, and broken cutter and cutter pawl be uniform to be fixed on the limit of body, and the quantity sum of broken cutter and cutter pawl equals the limit number of regular polygon.
As further improvement of the utility model, the limit number of described regular polygon body is preferably between 6～12 limits.
As further improvement of the utility model, described detent and positioning boss be shaped as cross.
As further improvement of the utility model, the cutting edge of described broken cutter is a curved edge; The cutting edge of described cutter pawl one side of something is a curved edge, and one side of something is the sharp sword of projection in addition.
As further improvement of the utility model, the cutting edge of described broken cutter is straight sword; The cutting edge of described cutter pawl one side of something is straight sword, and one side of something is the sharp sword of projection in addition.
As further improvement of the utility model, the quantity of described cutter pawl is preferably two or three.
The utility model compared with prior art, simple and ingenious structure, practical reliable, the cutting edge of cutter is little with the contact-making surface of waiting to pulverize object, cutting efficiency height, and cutter installs by bolt, change quick, easy to maintenance, long service life.
