Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

Example 1:

referring to fig. 1 to 7, the present embodiment provides a crushing blade assembly structure for a pulverizer, including: the primary crushing cutter 7, a mounting post 15 coupled with the primary crushing cutter 7, and an annular disc 19 coupled with the mounting post 15.

In detail, the assembling column 15 is penetrated with a feeding hole 16 which is concentrically distributed with the feeding hole 11 on the bin cover 4 of the mill along the axial direction; and one axial end of the assembling column 15 is matched and fixed with the primary crushing knife 7; and the annular disc 19 is matched and connected with the other axial end of the assembling column 15, and the annular disc 19 is provided with a through hole 20 which is concentric with the feeding hole 16 and is communicated with the feeding hole.

The primary crushing cutter 7 comprises a plurality of second crushing cutters 71 which enclose to form a circular ring structure. The plurality of second crushing cutters 71 included in the primary crushing cutter 7 can be fixedly connected with one axial end of the assembling column 15 through the screws in one-to-one correspondence, and under the structure, partial replacement is facilitated under the condition that the individual second crushing cutters 71 are failed in use, so that the use cost is reduced.

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 one end, extending into the grinding bin of the grinding mill, of the assembling column 16 after penetrating through the circular matching hole 17 is matched with the primary crushing knife 7; the other end of the mounting post 16, which is far away from the axial direction of the primary crushing knife 7, is matched and connected with an annular disc 19, wherein the annular disc 19 can be welded and fixed with the mounting post 16 or can be integrally formed with the mounting post 16.

Generally speaking, elementary garrulous sword 7 of this embodiment is realized through erection column 15 and is joined in marriage between storehouse lid 4, and the one end in the crocus storehouse of milling machine is stretched into behind storehouse lid 4 to specific elementary garrulous sword 7 assembly at erection column 15 running through, and the mesh of the degree of depth that stretches into in the crocus storehouse of milling machine after the adjustment is elementary garrulous sword 7 is joined in marriage with storehouse lid 4 to the degree of depth that stretches into in the crocus storehouse of milling machine can be realized to the as long as run through storehouse lid 4 through adjustment erection column 15 this moment. The in-process that specific material carries out the grinding in getting into the crocus machine, its refinement degree is realized through the friction clearance size between the broken sword of mutual friction, the aforesaid stretches into elementary garrulous sword 7 in the crocus storehouse through erection column 15 and is suitable for one of them broken sword structure that rubs the breakage to the material in the crocus storehouse promptly, so, the degree of depth that stretches into the crocus storehouse of milling machine after joining in marriage with cang gai 6 through adjusting elementary garrulous sword 7 can realize adjusting elementary garrulous sword 7 and stretch into the crocus storehouse in back and the crocus storehouse in the mesh of the size of the perpendicular clearance between other broken sword structures, can be with the final realization to the adjustment effect of material refinement degree.

In the above process, under the condition that the assembling column 15 extends into the grinding powder bin at different depths, the fixing effect on the position state of the assembling column 15 is realized through the matching connection of the annular disc 19 and one end of the bin cover, which is far away from the grinding powder bin. In an alternative embodiment, the annular disc 19 is coupled with the bin cover 4 through a screw adjustment structure to achieve a fixing effect for the assembling situation of the assembling column extending into the grinding bin at different depths.

Specifically, the screw adjusting structure of the present embodiment includes a first screw structure and a second screw structure that are provided on the annular disk 19 and around the circumferential direction of the through hole 20 uniformly and sequentially at intervals; 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 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 primary crushing knife 7 and the crushing knife structure in the grinding bin.

Specifically, referring to fig. 3 and 4 of the present embodiment, fig. 3 is a schematic diagram showing a matching structure between the bin cover 4 and the primary crushing blade 7 in an implementation situation, in which there is no vertical gap between the bin cover 4 and the annular disc 9, and at this time, the vertical gap between the crushing blade structure in the corresponding milling bin and the primary crushing blade 7 is relatively large; fig. 4 shows a schematic view of the connection between the bin cover 4 and the primary crushing blade 7 in another embodiment, in which a vertical gap exists between the bin cover 4 and the annular disc 9, and the vertical gap between the crushing blade structure in the corresponding grinding bin and the primary crushing blade 7 is reduced compared to the case of fig. 3.

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.
