Abstract

The utility model relates to a novel slow double-layer crusher, which is composed of a machine base (1), a material feed hopper (2), a material storage hopper (3), a motor (4), a transmission case (5), a housing (6), a bearing (7), an upper crushing knife (8), an upper crushing knife bar (9), an upper dead knife (10), a lower quick crushing knife (11), a lower slow crushing knife (12), a driving gear (13), an upper gear (14), a lower quick gear (15) and a lower slow gear (16). Due to the fact that a lower layer fine material structure of the utility model uses a quick movable knife and a slow movable knife, and the differential speed of the two movable knives is utilized to crush the material, the utility model has the advantages of high material crushing efficiency, less powder, low noise, high material discharge speed, the advantage that the staying time of particles in the machine is short, etc. The utility model is especially suitable for immediately recovering the crushing materials.

Description

Novel double-layer grinder at a slow speed

The utility model relates to a kind of size reduction machinery, particularly a kind of novel double-layer grinder at a slow speed.

Included a body on the existing double-layer grinder at a slow speed, included lower floor's disentegrated particles structure on the body, its lower floor's disentegrated particles structure adopts a moving knife and a dead knife to carry out particle.Its weak point is: particle efficient is low, powder is many, noise is big, discharge velocity is slow, the time of staying of particle in machine is long, then influence product quality (particle time of staying in machine is long can absorb airborne moisture content and change its rerum natura cause product quality to reduce) as reclaiming immediately.

The purpose of this utility model is to overcome the above-mentioned deficiency of prior art and a kind of particle efficient height, powder is few, noise is low, discharge velocity is fast novel double-layer grinder at a slow speed are provided.

The technical solution of the utility model is: novel double-layer grinder at a slow speed includes a body, includes lower floor's disentegrated particles structure on the body, and its lower floor's disentegrated particles structure adopts one fast one slow two moving knife, utilizes the differential of two moving knife to carry out particle.

Lower floor's disentegrated particles structure of the utility model body is owing to adopt one fast one slow two moving knife, utilize the differential of two moving knife to carry out particle, compared with prior art, have particle efficient height, powder is few, noise is low, discharge velocity is fast, characteristics such as the time that particle stops in machine is short, the recovery immediately that is particularly suitable for pulverizing material.

Below in conjunction with drawings and Examples detailed structure of the present utility model is further described.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the A-A cutaway view of accompanying drawing 1;

Accompanying drawing 3 is a gear drive schematic diagram of the present utility model;

Accompanying drawing 4 is the structural representation of slow broken cutter under the utility model;

Accompanying drawing 5 is the structural representation of fast broken cutter under the utility model.

As shown in drawings: novel double-layer grinder at a slow speed is by support (1), material bin (2), storage bin hopper (3), motor (4), gearbox (5) and organization, storage bin hopper (3), motor (4), gearbox (5) and body are installed on the support (1), material bin (2) is installed on the body, body is by casing (6), bearing (7), go up broken cutter (8), go up broken knife bar (9), last dead knife (10), following fast broken cutter (11), following slow broken cutter (12), driving gear (13), (14) cog, fast gear (15) and slow gear (16) composition down down, go up broken knife bar (9), fast broken cutter (11) and following slow broken cutter (12) are installed on the casing (6) by bearing (7) down, going up broken cutter (8) is installed on the broken knife bar (9), driving gear (13) is installed on the power output shaft (17) on the gearbox (5), (14) cog, slow gear (16) is installed in an end of broken knife bar (9) and following slow broken cutter (12) respectively and meshes with driving gear (13) down, and following fast gear (15) is installed in down an end of fast broken cutter (11) and meshes (as shown in Figure 3) with following slow gear (16).

During work, down fast broken cutter (11) and down slow broken cutter (12) respectively with fast gear (15) down and down slow gear (16) under the drive of driving gear (13), do quick with rotate at a slow speed that (rotating speed of following fast broken cutter is 150-180 rev/min, the rotating speed of slow broken cutter is 50-60 rev/min down), utilize both speed discrepancies to carry out particle.

Claims

1, a kind of novel double-layer grinder at a slow speed, it includes a body, includes lower floor's disentegrated particles structure on the body, it is characterized in that its lower floor's disentegrated particles structure adopts one fast one slow two moving knife, utilizes the differential of two moving knife to carry out particle.
