Straw crusher
Technical field
The utility model relates to a kind of disintegrating machine, particularly is used for the disintegrating machine of stalk.
Background technology
At present; The use straw power generation has become a new trend of domestic biomass power generation, but stalk is elongated and more pliable and tougher, when the boiler internal combustion, is difficult to feeding; And it is insufficient to burn; Optimal way is carried out effective break process to stalk exactly, and its granularity is reached in the 3-5cm scope, and the stalk fragmentation has become the bottleneck problem in the domestic biomass power generation production process.Existing straw crusher exceeds standard to the vexed car putty of the broken easy appearance of stalk flexible and that humidity is bigger, discharging-material size, and feed bin is fluffy stifled, and tool wear is fast and change inconvenience, has restricted the development of biomass energy source item.
The utility model content
The purpose of the utility model just is to deficiency of the prior art, provides a kind of release mesh stalk material working modulus high, and cutter changing is easy to straw crusher.
To achieve these goals; The technical scheme that the utility model adopts is such: a kind of straw crusher, comprise frame, power set and breaker, and described power set comprise electromotor and belt pulley; It is characterized in that: side, said frame top is provided with charging aperture; The charging aperture below is provided with quantitative feed and discharge device, and quantitatively feed and discharge device comprises turning cylinder and is installed in the quantitative charging and discharging transfer roller on the turning cylinder, and breaker comprises connecting axle and is installed in cutting disc and the fret-saw frame on the connecting axle; Turning cylinder and connecting axle are parallel to the front and back that horizontal plane is fixed on frame; Turning cylinder and connecting axle link with one group of belt pulley and electromotor respectively, and breaker is installed in the frame with quantitative feed and discharge device parallel axes symmetry, and the frame below is provided with discharging opening.
During work; Material is fed by charging aperture, gets into quantitative feed and discharge device, quantitatively charging and discharging transfer roller at the uniform velocity rotation under the drive of turning cylinder; Bring material into fracture area; Material receives shearing and the fragmentation of sawing and the cutting disc of the fret-saw frame on the connecting axle of high speed rotating, and the material after the processing is received the centrifugal force of breaker and the quantitatively effect of charging and discharging transfer roller, discharges from discharging opening.Material passes through at the uniform velocity feed of quantitative feed and discharge device; Make charging rate even; Prevent the generation of putty phenomenon; And material receives the effect of two power of shearing force of sawing force and the cutting disc of fret-saw frame simultaneously in fracture area, guaranteed the broken uniformity of material, has guaranteed the processing granularity of material.Because fret-saw frame and cutting disc all are to be installed on the connecting axle respectively, so the replacing of cutter very easily.
As the further improvement of the utility model,, make the admission velocity of material more even quantitatively at interval stock guide being installed on the charging and discharging transfer roller.
As the further improvement of the utility model, have on the described cutting disc and attach the angle of throat dish, described fret-saw frame is a kind of in monorow tooth fret-saw frame, three toothrow fret-saw frames, the spiral distributed tooth fret-saw frame, material more is prone to broken.
As the further improvement of the utility model, adopt electric control system to control charging, the fragmentation of disintegrating machine automatically, automaticity is high, more is prone to large-scale production.

Embodiment
To combine accompanying drawing and practical implementation that the utility model is described further below.
Referring to Fig. 1, the straw crusher of the utility model embodiment comprises frame 1, power set and breaker 8; Described power set comprise electromotor 2,12 and belt pulley 3,13, and side, frame 1 top is provided with charging aperture 4, and charging aperture 4 belows are provided with quantitative feed and discharge device 5; Quantitatively feed and discharge device 5 comprises turning cylinder 6 and is installed in the quantitative charging and discharging transfer roller 7 on the turning cylinder 6; Quantitatively at interval stock guide 15 is installed on the charging and discharging transfer roller 7, being provided with of batch turning plate 15 can make the stalk charging more even, referring to Fig. 2, Fig. 3; Breaker 8 comprises connecting axle 9 and the cutting disc 10 and fret-saw frame 11 that are installed on the connecting axle 9; Turning cylinder 6 is parallel to the front and back that horizontal plane is fixed on frame 1 with connecting axle 9, and turning cylinder 6 links with belt pulley 13 and electromotor 12, and connecting axle 9 links with belt pulley 3 and electromotor 2; Breaker 8 is installed in the frame 1 with quantitative feed and discharge device 7 parallel axes symmetries, and frame 1 below is provided with discharging opening.Referring to Fig. 4, Fig. 5, have on the cutting disc 10 and attach the angle of throat dish, can make the stalk fragmentation more complete, be more conducive to the fragmentation of flexibility, moist stalk.The straw crusher of the utility model embodiment adopts electric control system 16 inlet amount and the fragmentation of control stalk automatically, and automaticity is high, is more conducive to scale, suitability for industrialized production.
As preferably, fret-saw frame 11 is a kind of in monorow tooth fret-saw frame, three toothrow fret-saw frames, the spiral distributed tooth fret-saw frame, and these three kinds of fret-saw frames are higher to the degree of crushing of material.
During work; Stalk enters into quantitative feed and discharge device 5 through the conveying of conveyer 17 from charging aperture 4; Quantitatively charging and discharging transfer roller 7 at the uniform velocity rotation under the drive of turning cylinder 6 is taken stalk to fracture area, and stalk receives shearing and the fragmentation of sawing and the cutting disc 10 of the fret-saw frame 11 on the connecting axle 9 of high speed rotating; Stalk after the processing is received the centrifugal force of breaker 8 and the quantitatively effect of charging and discharging transfer roller 7, discharges from discharging opening 14.
Stalk passes through at the uniform velocity feed of quantitative feed and discharge device 7; Make charging rate even; Prevent the generation of putty phenomenon; And stalk receives the effect of two power of shearing force of sawing force and the cutting disc of fret-saw frame simultaneously in fracture area, guaranteed the broken uniformity of material, has guaranteed the processing granularity of material.Because fret-saw frame and cutting disc all are to be installed on the connecting axle respectively, so the replacing of cutter very easily.
