Abstract
The utility model provides a biomass fuel crusher. The energy consumption and equipment investment can be reduced by reducing driving motors, the cutter shaft crushing speed is consistent, and the crushing effect is improved. The biomass fuel crusher comprises a hopper, and two cutter shafts which are arranged in parallel, wherein the cutter shafts are respectively arranged on a bracket; one cutter shaft is a driving cutter shaft; the driving cutter shaft is connected with a reducer through a coupler; the reducer is connected with a motor; the two cutter shafts are respectively sleeved with cutter heads; the cutter heads on the two cutter shafts are embedded and are axially arranged in a staggered mode at an interval; the cutters are arranged along with the circumference of the cutter heads; the rotating directions of the two cutter shafts are opposite to each other; when the two cutter shafts rotate, cutting edges of adjacent cutters on the two cutter shafts are in a shear engagement shape; the lower part of the hopper is connected with a stripper plate; the stripper plate is guided into a cutter head engagement port of the two cutter shafts; and the biomass fuel crusher is characterized in that one ends of the two cutter shafts are respectively connected with gears; and the two gears are meshed with each other.
Description
Technical field
The utility model relates to a kind of disintegrating apparatus for the plant such as agricultural, the discarded object of production of forestry such as straw, fruit tree branch and bark and culled wood, tailing etc., is specially biomass fuel crusher.
Background technology
The discarded object waste wood bavin of the wastes straw of agricultural production, fruit tree branch and production of forestry, branch bar, bark etc. are all valuable biomass fuels, can be used as the fuel of boiler, after the boiler internal combustion, produce steam, are used for generating and heat supply.Biomass fuel is the reproducible energy, actively utilizes the primary energy such as bio-fuel Substitute For Partial oil, coal, for the consumption, the environmental contamination reduction that reduce primary energy, increase farmers' income, obvious Social benefit and economic benefit is arranged.
Biomass fuel must carry out fragmentation before sending into boiler combustion.Biomass fuel after fragmentation can be sent into boiler smoothly, adopt in the industry crusher in crushing, the structure of disintegrating machine adopts a cutter shaft, motor must run up during broken material like this, and single shaft is broken, and a part of material is normally stirred rotten, owing to not being shearing between cutter and cutter, so the crushing effect of material is undesirable, broken efficient is low.
Improvement for above-mentioned shortcoming is to adopt two arbor associations to carry out fragmentation, also used more motor to drive when adopting more cutter shaft, cause the increase on energy consumption, because two cutter shafts are to be driven by different motors, its broken speed is inconsistent, cause fragmentation inhomogeneous, crushing effect does not significantly promote.
Summary of the invention
For the problems referred to above, the utility model provides a kind of biomass fuel crusher, and it can reduce energy consumption and equipment investment by reducing drive motors, makes simultaneously the broken speed of cutter shaft consistent, improves crushing effect.
it is achieved through the following technical solutions: it comprises hopper, two cutter shafts that are arranged side by side, described cutter shaft is installed on respectively support, described cutter shaft wherein one be cutter shaft initiatively, described active cutter shaft connects reductor by shaft coupling, described reductor is connected with motor, described two cutter shafts are respectively installed with cutterhead, described cutterhead on two cutter shafts embeds mutually and the interval that axially misplaces is arranged, cutting knife is along the circumference of described cutterhead, described two cutter shaft direction of rotation, when two cutter shafts rotate on two cutter shafts adjacent cutting knife blade be and shear the interlock shape, the bottom of described hopper connects time flitch, and described time flitch imports the cutterhead articulation port of described two cutter shafts, and it is characterized in that: an end of described two cutter shafts is connected with respectively gear, described two engaged gears.
It is further characterized in that: described cutting knife is flush-mounted in described cutterhead and by trapezoidal wedge location, described trapezoidal wedge be positioned at described cutting knife front edge below, and be connected with screw between described cutterhead; Described cutting knife is nail pick shape, and front edge has the inclination angle, and it is circular-arc that the knife back is parabola; Cutting knife is " eight " font shearing interlock shape in relative rotation; The position that described cutter shaft combines with cutterhead, the outline of described cutter shaft, the endoporus of cutterhead are hexangle type; Circumferential cutting knife cutting edge along cutter shaft is arranged as screw type; Described time the flitch place is equipped with blower fan.
After the utility model adopts said structure, driven by motor initiatively cutter shaft is rotated, gear on the active cutter shaft is also along with rotation simultaneously, meanwhile drive from the gear of movable arbor and rotate, thereby also rotate from movable arbor, realize between much knives on corresponding cutter shaft that THE ADIABATIC SHEAR IN and speed are consistent, material can be shredded rapidly and uniformly like this, has improved shear effect.Single motor has only been used in such design, has reduced energy consumption and equipment investment.
