[0031] Four groups of connecting plates 13 are installed on the four sides of the outer wall of the rotating block 8. A clamping plate 14 is fixedly connected to one side of the connecting plate 13 away from the rotating block 8. A clamping plate 2 15 is fixedly connected to the top of the connecting plate 13 away from the side of the clamping plate 14.

A guide groove 18 is penetrated and opened in the middle of the milling blade clamping rod 17, and the guide groove 18 cooperates with the guide rod 12.
[0032] The end of the milling blade clamping rod 17 passing through the clamping plate 14 is fixedly connected with a connecting plate 19, and a side of the clamping plate 14 away from the clamping plate 2 15 is provided with an annular groove 10, and a side of the connecting plate 19 close to the clamping plate 14 passes through and is provided with an annular groove 21, and a spring 22 is fixedly connected inside the annular groove 21, and a side of the spring 22 away from the annular groove 21 is fixedly connected to the inside of the annular groove 20, and a side of the support plate 2 away from the motor 3 is provided with an annular guide groove 24, and a side of the connecting plate 19 away from the milling blade clamping rod 17 is fixedly connected with a pull ring 23;
[0033] One end of the guide rod 12 away from the slide groove 16 is formed into an oblique angle 27, and the oblique angle 27 slides in the annular guide groove 24;

[0035] Adopt the above scheme: turn on the motor 1 3 to rotate the rotating rod 4, the collar 5, the connecting rod 6, the mounting plate 7 and the rotating block 8, and rotate the fixed milling cutter to a position aligned with the grinding wheel 32.

[0039] A dust collector 33 is installed on one side of the outer wall of the working box 1, and the output end of the dust collector 33 passes through the working box 1 and is fixedly connected to a dust collection pipe 34;
[0040] The inner cavity of the working box 1 is provided with a material discharge trough 35 at the bottom of the rotating block 8, and a placement groove 36 is provided on the side of the inner cavity of the working box 1 away from the material discharge trough 35;
[0041] A box door 37 is provided on a side of the outer wall of the working box 1 away from the vacuum cleaner 33 , and a visual window 38 is provided in the middle of the box door 37 .
[0042] The above scheme is adopted: first, the pull ring 23 is pulled to make the milling blade clamping rod 17 slide out of the resistance to the clamping plate 15, and the spring 22 is stretched at the same time, and then the milling blade is placed between the clamping plate 14 and the clamping plate 15, and the pull ring 23 is loosened to make the milling blade clamping rod 17 inserted into the installation groove provided in the middle of the milling blade to fix the milling blade, and then the motor 1 3 is turned on to rotate the rotating rod 4, the collar 5, the connecting rod 6, the mounting plate 7 and the rotating block 8 to rotate the fixed milling blade to a position aligned with the grinding wheel 32, and at this time, the hydraulic cylinder 29 is turned on to drive the protective plate 30, the motor 2 31 and the grinding wheel 32 to descend, and then the motor 2 31 is turned on to rotate the grinding wheel 32 to grind the milling blade;
[0043] When the grinding wheel 32 is grinding the milling blade, the vacuum cleaner 33 can be turned on to absorb the dust and impurities generated during grinding through the vacuum pipe 34;
[0044] The unground milling blade can be placed in the placement slot 36, making it easy to take the milling blade;
[0045] The grinding condition of the milling blade in the working box 1 can be viewed through the viewing window 38 .
[0046] The working principle and use process of the present invention:
[0047] When it is necessary to grind the milling blade, first pull the pull ring 23 to make the milling blade clamping rod 17 slide out of the resistance to the clamping plate 15, and at the same time stretch the spring 22, and then place the milling blade between the clamping plate 14 and the clamping plate 15, loosen the pull ring 23, and insert the milling blade clamping rod 17 into the installation groove opened in the middle of the milling blade to fix the milling blade, and then turn on the motor 1 3 to rotate the rotating rod 4, the collar 5, the connecting rod 6, the mounting plate 7 and the rotating block 8 to rotate the fixed milling blade to a position aligned with the grinding wheel 32, and then turn on the hydraulic cylinder 29 to drive the protective plate 30, the motor 2 31 and the grinding wheel 32 to descend, and then turn on the motor 2 31 to rotate the grinding wheel 32 to grind the milling blade;
[0048] After the milling blade is polished, the motor 3 is continued to be turned on to rotate the rotating block 8. When the motor 3 drives the connecting rod 6 to rotate, the connecting rod 6 drives the guide rod 12 to rotate. When the guide rod 12 rotates to the bottom, the bevel 27 of the guide rod 12 will contact the contact plate 25 to push the guide rod 12 forward. At this time, the guide rod 12 will drive the limit plate 11 to slide in the limit groove 9 to compress the spring 10. At the same time, the guide rod 12 will slide in the slide groove 16. When the guide rod 12 slides in the slide groove 16, it will contact the guide groove 18, causing the milling blade clamping rod 17 to slide so that the milling blade clamping rod 17 releases the limit on the milling blade. At this time, the milling blade will fall into the discharge trough 35 due to the influence of gravity, and the polished milling blade will be collected through the discharge trough 35.
[0049] When the unloading of the polished milling blade is completed, the guide rod 12 is continued to be driven to rotate by the connecting rod 6. At this time, the guide rod 12 will be out of contact with the contact plate 25, and then the guide rod 12 will be reset through the limit plate 11 by the elastic force of the spring 10, and the milling blade clamping rod 17 will be reset by the elastic force of the spring 22. When the guide rod 12 is reset, it continues to rotate to make the bevel 27 of the guide rod 12 contact and make the guide rod 12 slide, so that the guide rod 12 contacts the guide groove 18, and at the same time, the milling blade clamping rod 17 slides again in the clamping plate 14 to leave space for the milling blade. At this time, the milling cutter can be placed between the clamping plate 14 and the clamping plate 2 15, and there is no need to pull the pull ring 23. Then the guide rod 12 will continue to rotate through the connecting rod 6 to make the bevel 27 of the guide rod 12 disengage from the interference with the contact plate 2 26. At this time, the guide rod 12 will reset the guide rod 12 through the limit plate 11 through the elastic force of the spring 10, and at the same time, the milling cutter clamping rod 17 will be reset through the elastic force of the spring 22 to insert the milling cutter clamping rod 17, and fix the milling cutter in the installation groove opened in the middle of the milling cutter. Repeat the above steps to fix the milling cutter during grinding and automatically unload the material.
