Detailed description of the invention
Fig. 1 is structural representation of the present utility model.The utility model comprises frame 17, frame 17 is fixed with shredder assemblies and electric machine assembly 18.Be connected by transmission component between electric machine assembly 18 and shredder assemblies.
Shredder assemblies comprises the dynamic grinding set 6 of cylindricality and determines grinding set 3.Determine grinding set 3 to be fixed in frame 17, determine grinding set 3 upper end and be fixed with upper cover 2, lower end is fixed with blanking bin 7.Upper cover 2 is fixed with hopper 1.Discharge nozzle 8 is fixed with under blanking bin 7.Discharge nozzle 8 place is provided with negative pressure device, can by the material sucking-off within blanking bin 7.
Dynamic grinding set 6 is cylindricality with determining grinding set 3, coaxially installs for axle center with rotating shaft 9.
Dynamic grinding set 6 is arranged on the inside of determining grinding set 3, has certain distance between the outer wall of dynamic grinding set 6 and the inwall determining grinding set 3, and the space that this distance is formed is for shearing track 20.Dynamic grinding set 6 is fixed on rotating shaft 9 by key 10.Dynamic grinding set 6 can be driven when then rotating shaft 9 rotates to rotate.
The outer wall of dynamic grinding set 6 is provided with dynamic grinding set tooth 16, and the inwall determining grinding set 3 is provided with determines grinding set tooth 15.
Transmission component comprises belt wheel 12 and driving-belt 13.Belt wheel 12 is fixed on rotating shaft 9 lower end by key 11, and driving-belt 13 one ends wound is on belt wheel 12, and the other end is connected with electric machine assembly 18, then, when electric machine assembly 18 operates, driving-belt 13 can be driven to rotate, and then band movable belt pulley 12 rotates.Belt wheel 12 driven rotary axle 9 rotates, and rotating shaft 9 drives dynamic grinding set 6 to rotate.
Key 10 and key 11 are used to the part on connecting axle and axle and play axial restraint effect, to reach the machine components of transmitting torque to the part on axle.
The utility model also comprises coolant jacket 4, and the lower end of coolant jacket 4 is provided with the penstock of cooling fluid, and the upper end of coolant jacket 4 is provided with the water output duct 19 of cooling fluid.Coolant jacket 4 is fixed on the outside of determining grinding set 3, is wrapped by the outer wall determining grinding set 3, coolant jacket 4 and determine to form the space of a certain capacity between grinding set 3, is used for keeping the cooling effect of cooling fluid.Penstock and water output duct spatially differ 180 °.
The utility model also proposed more excellent technical scheme, namely determines grinding set 3 for cylinder, and dynamic grinding set 6 is up-narrow and down-wide cone.The shearing track 20 determined between grinding set 3 and dynamic grinding set 6 is then made to narrow gradually from top to bottom.Fig. 2 is the schematic diagram shearing rail superior portion.Fig. 3 is the schematic diagram shearing rail inferior portion.Fig. 2 is relative to Fig. 3, the width shearing track 20 is wider, treat that mill object has now just entered and shear track 20, wider gap can be treated mill object and tentatively be ground, wait that grinding object falls into the bottom of shearing track 20 afterwards, thinner gap can be treated mill object and further be ground, and make degree of grinding darker, the object particle after grinding is less.
The utility model also comprises feed plate 5.Fig. 4 is the structural representation of feed plate.Feed plate 5 is impeller type, comprises axle center and take axle center as the blade of symmetrical centre, and be provided with linear baffle plate on front side of blade, rear side is arc line shaped.Be provided with cover plate on dynamic grinding set 6, feed plate 5 is fixing on the cover board.Feed plate 5 is fixed on rotating shaft 9 by axle center, when rotating shaft 9 rotates, cover plate and feed plate 5 can be driven together to rotate.
Workflow of the present utility model is as follows:
1, starter motor assembly 18, electric machine assembly 18 rotates, and drives transmission component, and then drives shredder assemblies running.
2, the material through preliminary coarse crushing is poured in hopper 1, material falls on the upper cover of dynamic grinding set 6, due on cover and be fixed with feed plate 5, feed plate 5 is in rotation, linear pattern baffle plate on front side of the blade of feed plate 5 promotes material, forces material all to enter by determining among shearing track 20 that grinding set 3 and dynamic grinding set 6 form.
3, stalk enters in the descending process of top shearing track 20, and dynamic grinding set 6 High Rotation Speed under electric machine assembly 18 drives, determines grinding set 3 position and fix.Stalk dynamic grinding set 6 outer surface dynamic grinding set tooth 16 and determine grinding set 3 inner surface determine the effect of grinding set tooth 15 under be subject to continuously shearing, grinding.Stalk moves downward on polished limit below in the effect of deadweight and negative pressure.From top to bottom more and more narrow owing to shearing track 20, stalk is sheared and grinds more and more thinner.
4, the penstock of circulating cooling liquid via coolant jacket lower end is introduced, through coolant jacket 4 and the space of determining between grinding set 3, reduce stalk because the temperature rise that produces of severe friction, then drawn by the water output duct 19 of the cooling fluid of coolant jacket upper end, form a circulation.Coolant jacket 4 and the gap of determining between grinding set 3 form the space of a certain capacity, to be used for keeping the cooling effect of cooling fluid.When overlooking coolant jacket 4, the position between visible penstock and water output duct 19 spatially differs 180 °, cooling fluid can be made like this at coolant jacket 4 and determine to stop the more time between grinding set 3, ensureing cooling effect further.
5, stalk is by after shearing track 20, falls into blanking bin 7, sends afterwards, complete pulverizing under the drive of the negative pressure of negative pressure device generation from the discharge nozzle 8 of blanking bin 7 lower end.
Above-described is only preferred embodiment of the present utility model, and the utility model is not limited to above embodiment.Be appreciated that the oher improvements and changes that those skilled in the art directly derive or associate under the prerequisite not departing from spirit of the present utility model and design, all should think and be included within protection domain of the present utility model.
