The above-mentioned connections may be direct connections or indirect connections via other components.

The top of the main shaft sleeve is connected with the main shaft cavity shell through a supporting structure. In this example, the supporting structure is a cylindrical support, as shown in fig. 1, the cylindrical support includes a first supporting cylinder 10, a second supporting cylinder, a third supporting cylinder and a fourth supporting cylinder, wherein the first supporting cylinder 10 is located between the air inducing port 7 and the air supplementing port 6, and the top of the baffle 11 is fixedly connected with the first supporting cylinder 10; a ventilation opening 13 is formed below the second supporting cylinder, the third supporting cylinder and the fourth supporting cylinder; an L-shaped reinforcing plate 14 is arranged on the outer side of the ventilation opening 13, the outer side of the reinforcing plate is fixedly connected with the shell of the main shaft cavity, and the lower side of the reinforcing plate is fixedly connected with the bottom plate of the main shaft cavity, so that the strength of the whole structure of the main shaft cavity is enhanced. Of course, the number of the supporting cylinders is not limited to four, and the shapes of the ventilation opening 13 and the reinforcing plate 14 are not limited to the illustrated shapes, and it will fall within the scope of the present invention as long as the airflow is ensured to form rotation around the main shaft, that is, the design concept of the present invention is satisfied.

The utility model discloses the induced air 7 is taken out from a large amount of air, causes the interior negative pressure suction that produces of breaker main shaft chamber 4 to the air that attracts broken chamber 3 and ejection of compact chamber 5 flows to main shaft chamber 4. After the air supply opening 6 is opened, a large amount of external air rushes into the main shaft cavity 4, and strong air flow which flows to the air induction opening 7 from the air supply opening 6 in a rotating mode is formed under the flow guiding of the baffle plate 11 and the air vent 13. The utility model discloses the high-speed rotation of rotor 8 can force the material to form the spiral whereabouts to influence the air and form the whirl, further strengthen breaker inside air and form rotatoryly. These strong air flows can carry away a large amount of fine particles, and a fine particle classification function is realized.

With reference to fig. 1 to 3, since the rotor crushes the material in high speed rotation, a large number of tiny particles will float in the crusher cavity, and the falling material will have a certain tendency to fall spirally when entering the main shaft cavity 4, as indicated by the solid line in fig. 2, so that the material will form an annular, relatively dispersed curtain of vertically downward material when entering the main shaft cavity 4. The strong circular air flow impacts the spirally falling material curtain in the horizontal direction, the horizontal impact forces the material to be dispersed again, in the process, the air scrubs the material particles and the collision among the material particles separates a large amount of tiny particles, and the tiny particles are carried by the air flow to flow towards the air induction port 7.

In practice, the inlet air to the crusher at the inlet 1 and outlet is minimized, but this is unavoidable. In addition, the air of the feeding port 1 is wrapped with the materials and enters the machine body, so that the air can be controlled only properly. As shown in figure 2, the utility model discloses formed and used induced air 7 as only induced air, feed inlet 1 and moisturizing wind gap 6 are main air inlet, and discharge gate 5 is the air access of supplementary air inlet. The material in the discharge cavity flows in the opposite direction to the air, and the air can generate scrubbing and small particle separation effects on the material particles.

The scrubbing and separating functions of the parts exist at the same time, air is wrapped with the tiny particles and flows into the air inlet together, and the tiny particles are finally discharged, so that the effect of grading the tiny particles while crushing is realized.

The side wall of the induced duct of the utility model is provided with a grid plate mounting hole, and bolt holes are arranged at the two sides of the mounting hole; the grating plate comprises a cover plate 12-1 and a frame 12-2 fixedly connected with the cover plate, and a plurality of layers of partition plates 12-3 are arranged in the frame 12-2; a sealing rubber pad is arranged around the inner side frame of the cover plate 12-1; bolt holes are arranged on two sides of the cover plate 12-1. The grid plate 12-1 is detachably arranged on the induced draft pipe 12, so that the grid plate can be independently overhauled.

Because what induced air mouth 7 attracted was come not only has the tiny particle, and partly great granule (this great granule indicates broken qualified granule of size) in addition, set up above-mentioned grid structure for blockking the discharge of great granule, grid structure can effectively block most great granule and get into the induced air pipeline. The partition plate 12-3 is made of wear-resistant materials, so that the abrasion is reduced, the service life of the grating is prolonged, and the operation and maintenance cost is saved. Preferably, the induced draft tube 12 is arranged to be inclined upward as a whole, and inclined upward by an angle of more than 45 degrees.

Different raw materials and different separation requirements can be realized by adjusting the wind pressure and the wind quantity of the induced wind port 7 and adjusting the size of the air supplement port 6. Reasonable arrangement of induced air and air inlet can generate better particle grading effect. The air inlet regulating plate is the same with 6 sizes in air supply opening, and air inlet regulating plate both sides are equipped with parallel bar hole, and mounting bolt, bolt and air supply opening shell are connected in the bar hole. The air inlet adjusting plate controls the air quantity and the wind power and controls the size of separated particles.

The utility model has the advantages that: the utility model has multiple purposes, can crush large-particle materials, can separate micro particles automatically and directly discharge qualified fine-particle materials; 2) the utility model discloses only set up induced air, fresh air inlet in the appearance on the casing of existing equipment, the induced duct is small, does not have the volume of the former breaker of increase almost, has saved the space problem that the grader occupy in other words.
