In an alternative case, the first primary crushing blades 6 and the second primary crushing blades 7 have the same structure.

In more detail, the first primary crushing cutter 6 comprises a plurality of first crushing cutters 61 which are enclosed to form a circular ring structure; and the second primary crushing cutter 7 comprises a plurality of second crushing cutters 71 which enclose to form a circular ring structure. The first crushing cutter 61 can be optionally matched and fixed with the circular grinding disc 2 through a screw, and the second crushing cutter 71 can also be optionally matched and fixed with the bin cover 4 through a screw, so that the structure is convenient for dismounting the first crushing cutter 61 and the second crushing cutter 71, and the using sharpness of the first crushing cutter 61 and the second crushing cutter 71 in the using process is effectively ensured.

Example 2:

referring to fig. 1 to 9, on the basis of the crushing mechanism of the flour mill of embodiment 1, the present embodiment provides a flour mill, including: a grinding bin 1, a bin cover 4 adapted to fit with the grinding bin 1 to form a grinding section, and the crushing mechanism of embodiment 1 adapted to a pulverizer. Wherein, an opening which is suitable for being blocked by a bin cover 4 is arranged on the grinding powder bin 1.

For the crushing mechanism suitable for the flour mill related to the embodiment, when the bin cover 4 covers the opening of the milling bin 1, the first primary crushing blades 6 on the bin cover 4 and the second primary crushing blades 7 on the circular grinding disc 2 are distributed oppositely, and a gap suitable for passing materials is formed between the two.

Specifically, a feed inlet 11 suitable for feeding is provided on the cover 4, and a hopper 13 can be disposed on the feed inlet 11. And the side wall of the milling bin 1 is also provided with a discharge hole which is connected with a discharge pipe 12 in a matching way. The feed inlet 11 can be opened on the bin cover 4 at a position corresponding to the central hole 8 formed between the first primary crushing knife 6 and the second primary crushing knife 7, so that the material can directly enter the first primary crushing knife 6 and the second primary crushing knife 7 through the feed inlet 11 to be crushed and processed.

The specific milling principle for the mill of this embodiment is as follows:

the material is fed into a central hole 8 formed between the first primary crushing knife 6 and the second primary crushing knife 7 through a feed port 11 on the bin cover 4, the second primary crushing knife 7 rotates synchronously along with the rotation of the circular grinding disc 2, in the process, the material is primarily crushed by the first primary crushing knife 6 and the second primary crushing knife 7 to be crushed, the primarily crushed material enters a gap formed between the first primary crushing knife 6 and the second primary crushing knife 7, and the material at the gap formed between the first primary crushing knife 6 and the second primary crushing knife 7 is further crushed and refined under the friction action of the first primary crushing knife 6 and the second primary crushing knife 7. For the refined materials, the materials are sent to the lower part of the powder grinding cutter 3 on the circular grinding disc 2 to be further crushed by the powder grinding cutter 3 due to the action of centrifugal force, and finally the completely crushed materials are sucked out by the suction fan through the discharge hole 12.

Example 3:

referring to fig. 10 to 15, on the basis of the flour mill of embodiment 2, the flour mill provided by this embodiment can also adjust the degree of material crushing and refining, because the specific refining of the material is realized by the mutual friction between the first primary crushing blade 6 and the second primary crushing blade 7, and thus the adjustment of the degree of material crushing and refining can be realized by adjusting the vertical distance between the first primary crushing blade 6 and the second primary crushing blade 7. And the connection between the bin cover 4 and the grinding bin 1 is fixed and not adjustable, so that the sealing property of the space in the grinding bin 1 during grinding is ensured, and the materials are prevented from dissipating after being refined. Therefore, the present embodiment achieves the effect of adjusting the vertical gap between the second primary crushing blade 7 and the first primary crushing blade 6 by adjusting the assembling process between the second primary crushing blade 7 and the bin cover 4.

In detail, the second primary crushing knife 7 is matched and connected with the bin cover 4 through a hollow and cylindrical assembling column 15; the second primary crushing knife 7 is matched and fixed with one axial end of the assembling column 15; the assembly column 15 has a feed opening 16 arranged concentrically with the feed opening 11. The second primary crushing blade 7 here includes a plurality of second crushing blades 71 which can be fastened to one axial end of the fitting post 15 by screws.

In addition, more specifically, a circular matching hole 17 through which the assembling column 16 penetrates is formed in the bin cover 4 around the circumferential direction of the feed port 11, and after the assembling column 16 penetrates through the circular matching hole 17, the assembling column is matched and connected with the second primary crushing knife 7 towards one end of the first primary crushing knife 6; the other end of the assembly column 16, which is far away from the second primary crushing knife 7 in the axial direction, is matched and connected with an annular disc 19, wherein the annular disc 19 can be welded and fixed with the assembly column 16 or can be integrally processed and formed with the assembly column 16; the annular disc 19 is provided with a through hole 20 which is concentric with the feeding hole 17 and is communicated with the feeding hole; and the annular disc 19 is matched and connected with the bin cover 4 through a screw rod adjusting structure.

In an alternative embodiment, the screw adjustment structure comprises a first screw structure and a second screw structure provided on the annular disc 19 and evenly and sequentially at intervals around the circumferential direction of the through hole 20; namely, the first screw structures and the second screw structures are alternately distributed. Wherein the first screw structure is suitable for simultaneously penetrating the annular disc 19 and the bin cover 4 to realize the matching between the annular disc 19 and the bin cover 4; the second screw structure is only suitable for penetrating the annular disc 19, one end of the second screw structure penetrating the annular disc 9 and facing the bin cover 4 abuts against the end face, away from the second primary crushing knife 7, of the bin cover 4, namely, the annular disc 19 is firmly connected with the bin cover 4 through the matching of the first screw structure and the second screw structure, the distance between the annular disc 19 and the bin cover 4 is adjusted through the matching of the first screw structure and the second screw structure, and the adjustment of the distance corresponds to the vertical gap between the second primary crushing knife 7 and the first primary crushing knife 6.

Specifically, referring to fig. 12 and 13 of the present embodiment, fig. 12 is a schematic diagram illustrating an engaging structure between the bin cover 4 and the second primary crushing blade 7 in an implementation case, in which there is no vertical gap between the bin cover 4 and the annular disc 9, and the corresponding vertical gap between the first primary crushing blade 6 and the second primary crushing blade 7 is correspondingly larger; fig. 13 is a schematic view showing an engaging structure of the bin cover 4 and the second primary crushing blade 7 in another embodiment, in which a certain vertical gap exists between the bin cover 4 and the annular disk 9, and the vertical gap between the corresponding first primary crushing blade 6 and the second primary crushing blade 7 is reduced as compared with the case of fig. 12.

Referring to the drawings of the present embodiment, the first screw structure includes a first screw 21 adapted to be inserted into the bin cover 4 after one end of the first screw passes through the annular disc 19, and a first end cover 22 sleeved on an end of the first screw 21 far from the bin cover 4. The second screw structure includes a second screw 24 having one end penetrating the annular disc 19 and abutting against the side end surface of the cover 4 facing the annular disc 19, a second end cap 26 sleeved on one end of the second screw 24 away from the cover 4, and a nut 25 sleeved on a portion of the second screw 24 between the second end cap 26 and the annular disc 19. In a specific use process, since one end of the first screw 21 penetrating through the annular disc 19 is inserted into the bin cover 4, therefore, the vertical clearance between the annular disc 19 and the cover 4 can be adjusted by adjusting the depth of the first screw 21 inserted into the cover 4, in order to effectively maintain the stability of the position of the annular disc 19 relative to the bin cover 4 after the depth of the first screw 21 inserted into the bin cover 4 is adjusted, the present embodiment is implemented by a second screw structure, in detail, the second screw 22 is not inserted into the bin cover 4 after penetrating through the annular disc 19, but the second screw 22 is abutted against the end face of the bin cover 4 facing the annular disc 19, and the stability of the position of the annular disc 19 relative to the bin cover 4 can be realized only by abutting the second screw 22 against the bin cover 4 facing the annular disc 19 and matching with the nut 25 to realize the relative locking between the second screw 22 and the annular disc 19.
