Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

Referring to Fig. 1, this utility model provides a kind of technical scheme: a kind of grater being applicable to primary comminution, including Work box 1, the middle part of work box 1 inner chamber is provided with crushing chamber 13, and the both sides of crushing chamber 13 are all run through pulverizing knife rest 12, crushing knife The inner side of frame 12 is mounted on crushing knife, and the quantity pulverizing knife rest 12 is two groups, and the crushing knife of crushing chamber 13 both sides is mutual Engagement, it is simple to hit, the outside pulverizing knife rest 12 is provided with pulverizing hammer 11, pulverizes hammer 11 by the slide bar 10 being arranged on chute Being connected with crank connecting link 16, the other end of crank connecting link 16 is arranged on the surface of rotating disk 2, the back of rotating disk 2 by output shaft with Second motor 9 connects, and the bottom of crushing chamber 13 connects has feed box 8, the top of feed box 8 to be provided with grinding gear by pedestal 5, the rotating shaft of grinding gear 5 is connected with the first motor 7 by transmission band 6.

Originally be applicable to the grater of primary comminution, simple in construction, easy to use, use first pass through pulverizing hammer 11 and with its phase The crushing knife coordinated, it is possible to directly the hard material entered in crushing chamber 13 is carried out impact and pulverize so that it is pulverize dynamics higher, Crushing effect is more preferable, is then rubbed by grinding gear 5, is greatly improved the grinding property of grater, due to gravity Reason, object, when not pulverized completely, is stuck in the bottom of crushing chamber 13, the design that its grinding gear 5 is meshed, large-scale not by The material of fragmentation, will not be entered wherein by strand, until after the most crushed hammering of material is broken, the material middle part by grinding gear 5 Engaged gap, is entered in feed box 8 by rubbing so that it is the effect of primary comminution is more preferable, avoids the damage of grinding gear 5 simultaneously Bad, further increase the work efficiency of grater, make to grind the speed of work faster, be suitable for promoting the use of.

Grinding gear 5 is suitable with the bottom of crushing chamber 13, and grinding gear 5 is arranged on the bottom of crushing chamber 13, and powder The top in broken chamber 13 is provided with infundibulate charging aperture, it is simple to it keeps off needing the material pulverized in crushing chamber 13, it is to avoid not by powder Broken complete material is directly entered in feed box 8 by grinding gear 5, is greatly saved the cycle-index of work, makes the matter of work Amount is more preferably.

The inwall of work box 1 both sides is all provided with the second motor 9 by motor rack 3, motor rack 3 by motor stand 17 with The top of work box 1 inner chamber and bottom connect, and motor rack 3 and the design of motor stand 17, make motor stabilizing is fixed on work In the inner chamber of case 1.

Outside slide bar 10, top and the bottom of chute are mounted on fixed mount 15, slide bar 10 and the junction set pulverizing hammer 11 It is connected to fixing shock ring 14, the design of fixing shock ring 14, on the one hand improves slide bar 10 and pulverize be connected between hammer 11 steady Qualitative, still further aspect also makes pulverizing hammer 11 impact when, and the vibrations transmitted are less.

Operation principle: during use, first puts into the feeding mouth needing comminution of material to melt crushing chamber 13 top, then starts Second motor 9 and the first motor 7, the second motor 9 drives pulverizing hammer 11 to impact material, treats that material is impacted completely in conjunction During the size fitted, its gap engaged by two grinding gears 5 is rubbed, thus drops in turnover hopper 8, at the beginning of completing Level comminution process.

Further improvement of this embodiment, described first motor and the second motor are all double-speed motors, so according to pulverizing Demand may select the regulation of motor speed, to strengthen practicality and versatility

Embodiment the most of the present utility model, for the ordinary skill in the art, It is appreciated that in the case of without departing from principle of the present utility model and spirit and these embodiments can be carried out multiple change, repair Changing, replace and modification, scope of the present utility model is defined by the appended claims and the equivalents thereof.
