A kind of straw crusher

Technical field

The present invention relates to the technical field of biomass material break process equipment, be specially a kind of straw crusher.

Background technology

The biomass materials such as agricultural crop straw and fruit tree branch are a kind of available resources, are also a kind of green energy resources, can be used for the fields such as burning electricity generation.But all want broken with reduced in size, so that the operations such as follow-up conveying, compacting, burning are normally carried out utilizing as last.But because this class material is light, soft, the characteristics such as easily compression, winding, are easy to occur the problems such as disintegrating machine blocking, heating, blade be easy to wear during fragmentation.On market, never have desirable breaker.The fragmentation adopting at present mainly contains following several form:

1. utilize the tup of High Rotation Speed to clash into broken, this is to belong to blunt to hit, and relies on the tup of High Rotation Speed to impact material, makes its fragmentation (rotating speed is generally thousands of turning per minute), generally can only be for material hard, crisp class, as class raw materials such as branch, plank, tree roots.For soft meeting, encase tup, produce blocking, cannot work.Owing to being High Rotation Speed, quick abrasion, the service life of tup is also shorter, and spare parts consumption is higher.

2. the movable blade chip of High Rotation Speed is broken, and this fragmentation is with being contained in one group of blade that has cutting edge on rotation rotor, material being cut.It is movable that blade is equipped with on rotor, is not easy blocking, can be used for cutting the raw material of soft class.But because blade is more frivolous, can not be for the raw material of broken hard.This class breaker is also that High Rotation Speed (rotating speed is generally thousands of turning per minute) blade is easy to rust in addition, within general several days, just need to change one time blade.

3. also having a kind of is knife roller type, by a fixing stationary knife and one, 3-8 is housed the rotor of cutter is formed.During work, between stationary knife and rotor, there is very little gap, utilize shearing mechanism cutting.The cutter of this product needs very sharp could cutting, so cutter more easily weares and teares, and is linear feed, also easy blocking.

Summary of the invention

For the problems referred to above, the invention provides a kind of straw crusher, effectively prevent the blocking of disintegrating machine, heating in process, and reduced the wearing and tearing of processing blades, the service life of having improved processing blades.

Its technical scheme is such, a kind of straw crusher, it comprises underframe, on described underframe, be provided with discharging opening, on described underframe, corresponding described discharging opening is provided with stationary knife, and corresponding described stationary knife is provided with the moving knife roller coordinating with described stationary knife, on described moving knife roller, be provided with moving knife, the described moving knife edge of a knife and described stationary knife edge of a knife indention, described moving knife roller is arranged on rotating shaft, and described moving knife roller rotates around rotating shaft.

It is further characterized in that: on described moving knife roller, be provided with a plurality of moving knife cutter heads; On described underframe, corresponding described discharging opening is provided with a plurality of stationary knifes, and corresponding described stationary knife is provided with the moving knife roller coordinating with described stationary knife respectively.

In said structure of the present invention, because corresponding discharging opening on underframe is provided with stationary knife, corresponding stationary knife is provided with the moving knife roller coordinating with stationary knife, on moving knife roller, be provided with moving knife, the moving knife edge of a knife and stationary knife edge of a knife indention, described moving knife roller is arranged on rotating shaft, moving knife roller rotates around rotating shaft, moving knife and stationary knife coordinate the fragmentation that has realized stalk and fruit tree branch, the blade side of profile of tooth can be sheared, front can crush, between moving knife and the tooth of stationary knife, also has role of tear, material is broken, therefore can adapt to the fragmentation of various materials, broken material drops out from discharging opening, effectively prevented the blocking of disintegrating machine in process, heating, and the wearing and tearing of processing blades have been reduced, improved the service life of processing blades.

Accompanying drawing explanation

Fig. 1 is that straw crusher master of the present invention looks schematic diagram;

Fig. 2 is the top view of Fig. 1;

Fig. 3 is that moving knife and stationary knife coordinate schematic diagram.

The specific embodiment

See Fig. 1, a kind of straw crusher, it comprises underframe 1, on underframe 1, be provided with discharging opening 2, on underframe, corresponding discharging opening 2 is provided with manyly stationary knife 3, and corresponding stationary knife 3 is provided with coordinate with stationary knife many moving knife roller 4, moving knife roller 4 comprises a plurality of moving knife 5, moving knife 5 edges of a knife and stationary knife 3 edge of a knife indentions, moving knife roller 4 is arranged on rotating shaft 6, and moving knife roller 4 is around rotating shaft 6 rotations.

In conjunction with Fig. 1, operation principle of the present invention is described:

Hello barrel 7 is bearing on underframe 1 by support roller 8, and drives hello barrel low speed rotation by hello barrel drive unit 9.Material 10 is contained in hello barrel 7, the 3-6 being fixed on feeding barrel drives material 10 to rotate together material poking fork 12, the material of rotation constantly passes through moving knife roller 4, a plurality of moving knife 5 are housed on moving knife roller, under moving knife 5 hooks material, coordinate with stationary knife 3 respectively to form and shear pair, material is cut off, from discharging opening 2, fall.Bearing 11 is equipped with at moving knife roller two ends, and drives by moving knife roll driving apparatus 13.

The present invention has following technique effect:

1. moving knife cutter head and stationary knife all adopt the zigzag edge of a knife, rather than the straight edge of a knife.When shearing, material can not slide like this, material can be stuck between moving knife cutter head and the tooth of stationary knife and disperse to cut.The problem of having avoided straight cutter material to slide and finally gather together and can't cut;

2. moving knife cutter head of the present invention and stationary knife are to rely on lateral shear, so toothed blade thickness can be larger, can accomplish that 30-70mm is thick, so intensity is high.For raw materials such as hard stalk, branches, the increment of point can be by material pressure break, thereby is convenient to shear;

3. because moving knife cutter head and stationary knife are to rely on lateral shear, along rotating shaft axially can arrange more moving knife roller, some moving knife cutter head along circumferentially having again on each moving knife roller, therefore have tens of moving knife cutter head, operating efficiency is high, and output is large, is applicable to large-scale production;

4. many kinds of crumbling method comprehensive functions.Moving knife cutter head and the stationary knife side of profile of tooth can be sheared, and front can crush, and also have role of tear between moving knife and the tooth of stationary knife, and material is broken, and therefore can adapt to various materials.Many kinds of force compound action crushing efficiency significantly improves;

5. low speed is broken, and smashing principle of the present invention is to shear, crush and tear, rather than relies on impulsive force that material is smashed, and does not therefore need very high speed, generally per minute, hundreds ofly turns following.Therefore the wearing and tearing of cutter are slow, long service life.
