The adjusting assembly is used for adjusting the distance between the two crushing rollers 6, the adjusting assembly comprises an adjusting screw rod 4 which is rotatably connected to the transverse arrangement of the shell 2, the two adjusting screw rods 4 are mutually parallel (respectively positioned at the front side and the rear side of the shell 2), and the adjusting screw rod 4 is perpendicular to the crushing rollers 6. Adjusting screw 4 is gone up the cover and is equipped with connecting seat 5 with it threaded connection, and the equal sliding connection in casing 2 in bottom of connecting seat 5, and crushing roller 6 rotates to be connected on connecting seat 5.

The milling cutter 9 subassembly is used for restoreing the roll face of crushing roller 6, and the milling cutter 9 subassembly includes through bolted connection guide rail 7 and the milling cutter seat 8 of sliding connection on guide rail 7 on a supporting bench 3, installs on the milling cutter seat 8 can with the milling cutter 9 of roll face contact, and in this embodiment, the connected mode of milling cutter 9 and milling cutter seat 8 and the using-way of milling cutter 9 are prior art. The guide rail 7 is rotatably connected with a driving screw rod 10, and the milling cutter seat 8 is sleeved on the driving screw rod 10 and is in threaded connection with the driving screw rod 10. A servo motor for driving the screw rod 10 is fixed on the guide rail 7 through a bolt.

The driving assembly is used for driving the crushing roller 6 to rotate, the driving assembly comprises a driving motor 11 which is connected to the rack 1 in a sliding mode, the sliding direction of the driving motor 11 is perpendicular to the axial direction of the crushing roller 6, and a bolt is connected between the driving motor 11 and the rack 1; the end of the crushing shaft penetrates through the side wall of the machine shell 2 and is coaxially and fixedly connected with a crushing wheel 12, a lightening hole is formed in the crushing wheel 12, a driving belt 13 is connected between an output shaft of the driving motor 11 and the crushing wheel 12, and a 10% rotation speed difference exists between the two driving motors 11. A speed reducing motor 14 which is connected to the frame 1 in a sliding mode is arranged on the side portion of the driving motor 11, the sliding direction of the speed reducing motor 14 is the same as that of the driving motor 11, a bolt is connected between the speed reducing motor 14 and the frame 1, and a chain 15 is connected between an output shaft of the speed reducing motor 14 and an output shaft of the driving motor 11.

The specific implementation process is as follows: when the raw material is crushed, after the raw material is fed from the machine shell 2, the driving motor 11 is started, the driving motor 11 drives the crushing rollers 6 to rotate through the driving belt 13, and because a 10% rotation speed difference exists between the two crushing rollers 6 (the driving motor 11), the raw material can be crushed through differential motion of the two crushing rollers 6.

Along with the extension of live time, the damage such as pit can appear on the surface of crushing roller 6, need repair the roll surface this moment, when repairing the roll surface, need crushing roller 6 slow rotating, connect chain 15 between the output shaft of driving motor 11 and the output shaft of gear motor 14 this moment, close driving motor 11, start gear motor 14, gear motor 14 is the direct power source this moment, and driving motor 11 is the power transmission device of passive operating.

After the roller surface on one side is repaired, the guide rail 7 is detached from the support table 3 on one side and is installed on the support table 3 on the other side, and the operation is repeated to finish the repair of the other roller surface.

After the roller surface is repaired, the distance between the two roller surfaces is increased, and at this time, in order to ensure the crushing effect of the raw materials, the distance between the roller surfaces of the two crushing rollers 6 needs to be readjusted to 0.3-0.5 mm. At this moment, the operator rotates the adjusting screw rod 4, the adjusting screw rod 4 rotates to drive the connection in threaded connection with the adjusting screw rod to move transversely along the shell 2, and further drive the crushing roller 6 at the right end to move leftwards and the crushing roller 6 close to the left end, and when the distance between the roller surfaces of the two crushing rollers 6 is adjusted to be 0.3-0.5mm, the position of the crushing roller 6 is corrected again.

According to the technical scheme, when the roll surface of the roll pair is damaged, the roll surface can be milled and repaired by the aid of the repairing mechanism without being integrally replaced, and equipment investment is reduced.

Example two

As shown in fig. 2 and fig. 3, the present embodiment is different from the first embodiment in that: in this embodiment, a mud scraping mechanism is further disposed in the casing 2, the mud scraping mechanism includes a rotating shaft 16 rotatably connected in the casing 2, the rotating shaft 16 is parallel to the axial direction of the crushing roller 6, the rotating shaft 16 is located below the crushing roller 6, and a mud scraping plate 17 which can abut against the outer wall of the crushing roller 6 is welded on the rotating shaft 16 along the axial direction thereof.

When the crushing roller is used in practice, the raw materials crushed by the roller machine comprise clay, shale, limestone and the like, and when the crushing roller is used for crushing, the raw materials are adhered to the surface of the crushing roller 6 due to certain adhesion, so that the subsequent crushing effect on the raw materials is influenced. The scraper 17 is used for scraping off the mud adhered to the roller surface, and when the crusher roller 6 is used, the scraping off process is completed when the roller surface moves relative to the scraper 17 in the rotating process. After the roller surface is repaired, the distance between the roller surface and the mud scraper 17 can be changed, and a gap can be formed between the mud scraper 17 and the roller surface, so that the mud scraper 17 can not abut against the roller surface any more to cause ineffective mud scraping. At this moment, the position of the mud scraper 17 needs to be adjusted, an operator rotates the driving arm 18, the driving arm 18 rotates to drive the rotating shaft 16 coaxially and fixedly connected with the driving arm to rotate, the rotating shaft 16 drives the mud scraper 17 to rotate by a certain angle in the rotating process and to abut against the roll surface again, and at this moment, the fixing of the position of the driving arm 18 is realized again through the fixing nut 20 and the threaded column 19, so that the stable support of the mud scraper 17 is ensured.
