The utility model adopts said structure, to improve the ability of the intermediate product of pulverizing conglomeration caking.Drive unit is connected with framework and Drive frame reciprocally swinging, its process is as follows: drive unit lifts framework one end, the other end falls, in process, being positioned at the intermediate product that lifts one end will be thrown to then falling to the one end falling in the air, make the intermediate product pulverizing of conglomeration caking under the effect of gravity.And so forth, can greatly improve the ability of the intermediate product of pulverizing conglomeration caking, thereby improve smashing capability of the present utility model.
Further, the rectangular column that described housing is hollow, is provided with symmetrical arc convex on the left surface of described housing and right flank, and arc convex is connected by Horizontal limiting section with housing, and the end of described framework contacts with the inner surface of arc convex.
The movement locus of framework end is circular arc, and when preventing that framework from swinging, the intermediate product of filtered falls down from the gap between framework end and housing, and arc convex is set.The movement locus of the shape of arc convex and framework end adapts, and framework is contacted with the inner surface of arc convex all the time in swing process, prevents that the intermediate product of filtered from falling down from the gap between framework end and housing.
Further, the end of described framework offers groove, is provided with rubber sealing block in groove, between the bottom of rubber sealing block and groove, by spring, is connected.
In order further to improve sealing effectiveness, prevent that after framework end or the wearing and tearing of arc convex inner surface, intermediate product falls down from the gap between framework end and housing, and rubber sealing block is set.Under the effect of spring, rubber sealing block is affixed on the inner surface of arc convex all the time, thereby guarantees sealing effectiveness.Meanwhile, the inner surface that rubber sealing block also can prevent arc convex is set and is worn, increased service life of the present utility model.
Further, the top of described housing is provided with feed pipe.
Further, described drive unit comprises the semicircle projection that is arranged at described framework two ends, rotation is arranged at the motor that cam on housing and driving cam rotate, and cam is positioned at described framework below corresponding with semicircle projection, and the angle of the semicircle projection at described framework two ends differs °.
Cam rotation, the cam of framework one end and semicircle bump contact, the cam of the while framework other end not with semicircle bump contact, thereby one end of framework is lifted, the other end falls, and realizes the reciprocally swinging of framework.
Further, also comprise the powder collecting box that is arranged at described housing bottom.
In sum, advantage of the present utility model and beneficial effect are:
1. drive unit is connected with framework and Drive frame reciprocally swinging, can greatly improve the ability of the intermediate product of pulverizing conglomeration caking, thereby improve smashing capability of the present utility model;
2. arc convex is set, and the movement locus of the shape of arc convex and framework end adapts, and framework is contacted with the inner surface of arc convex all the time in swing process, prevents that the intermediate product of filtered from falling down from the gap between framework end and housing;
3. rubber sealing block is set, and under the effect of spring, rubber sealing block is affixed on the inner surface of arc convex all the time, thereby guarantees sealing effectiveness, has improved sealing property.
