Embodiment

Below, by reference to the accompanying drawings and embodiment, the utility model is described further:

As Figure 1-5, for the material crushing device that a kind of sieve aperture of the present utility model is adjustable, comprise bracing frame 1, the broken case 2 being fixedly mounted on bracing frame 1, the the first sieve cover being arranged in broken case 2, the broken shaft 4 being installed in rotation in the first sieve cover, for the motor 5 driving broken shaft 4 to rotate, the hopper 6 being connected is overlapped with the first sieve, for by mass transport to the feeding device in hopper 6, the perisporium of described first sieve cover is provided with multiple first sieve aperture, the bottom of described broken case 2 is communicated with batch can 7, the bottom of described batch can 7 is connected with fines pipe 8, the bottom right side of described first sieve cover has offered the first coarse fodder outlet 9, the periphery wall of described broken shaft 4 is provided with multiple crushing cutter 10, the periphery wall of described broken shaft 4 is also provided with spiral spiral plate 11, described spiral plate 11 extends along the axial direction due of broken shaft 4,

Described broken shaft 4 is in round table-like, the transversal disc diameter of its right-hand member is greater than the transversal disc diameter of left end, described first sieve cover comprises the thin broken cover 13 that thick broken cover 12 is connected with thick broken cover 12, described thick broken cover 12 and thin broken cover 13 are all in cylinder shape, and the inner diameter values of described thin broken cover 13 is less than the inner diameter values of thick broken cover 12. When the installation of reality, broken shaft 4 can be arranged on the two ends of broken case 2 by bearing support 41.

Material first can slightly break work in thick broken cover 12, some inherently less particle or through the material of the first sieve aperture, then can also pass the first sieve aperture, fall in batch can 7, then flow out from fines pipe 8 after slightly broken work. After slightly broken work, still through the material of the first sieve aperture, then, under the helical feed of spiral plate 11, cannot be transported in thin broken cover 13. Owing to the transversal disc diameter of broken shaft 4 is greater than the transversal disc diameter of left end, and the inner diameter values of thin broken cover 13 is less than the inner diameter values of thick broken cover 12, now just material can be carried out thin broken work. After thin broken, through the material of the first sieve aperture, then through the first sieve aperture, can fall in batch can 7, then flow out from fines pipe 8.After thin broken, the larger particles that part cannot be broken then exports 9 outflows from the first coarse fodder. When actually operating, the first coarse fodder can be exported the material flowed out at 9 places and again put into hopper 6, repeat an above-mentioned broken job.

And, the gap-ratio between spiral plate 11 and the first sieve cover is more identical, and spiral plate 11 can be scraped the material sticked on the first sieve cover wall face and fall, and continues by the right of spiral plate 11 helical feed to the first sieve cover. That is spiral plate 11 mainly plays two effects in the utility model, and the first is by the right-hand member of material from left end helical feed to the first sieve cover of the first sieve cover, and it two is the effect playing scraper.
