Compared with prior art, the utility model has a beneficial effect following outstanding:
1st, the utility model is in rotation process, grinding rod mutual not collision friction in rotation process, grinding rod with
Also do not contact between neck bush, thus avoid grinding rod and the unnecessary CONTACT WITH FRICTION of neck bush, improve grinding rod and interior
The service life of lining.；
2nd, neck bush of the present utility model and grinding rod are made up of corundum, and its hardness is big, wearability good and intensity high, improve
Grinding efficiency.
Brief description
Fig. 1 is structural representation of the present utility model.
Fig. 2 is internal structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with specification drawings and specific embodiments, the utility model is further illustrated.
As shown in Figure 1, 2, the utility model includes cylinder the 1st, cover the 2nd, grinding rod the 8th, central gear the 12nd, planetary gear the 9th, OK
Carrier 13 and gear ring 6.
Described cylinder 1 is provided with the cavity of an one end open, and the bottom of described cylinder 1 cavity is provided with a gear ring 6, institute
One end of the bottom wall central of the cylinder 1 stated and a rotary shaft 10 for being rotatably connected, the gear hole of described central gear 12 with
Rotary shaft 10 connects, the centre bore of described planet carrier 13 and rotary shaft 10 for being rotatably connected, described rotary shaft 10 with
One end of two connecting plates 11 connects, and is provided with grinding rod 8 between two connecting plates 11, the two ends of described grinding rod 8 respectively with even
The other end of fishplate bar 11 is for being rotatably connected.
The gear hole of described planet carrier 13 and multiple planetary gears 9 for being rotatably connected, described planetary gear 9 with too
Sun gear 12 external toothing, described planetary gear 9 and gear ring 6 internal messing.Described planetary gear 9 and one end of grinding rod 8 are
Being rotatably connected, the other end of described grinding rod 8 is provided with a guiding bearing pin.When central gear 12 rotates, row can be driven
Star gear 9 limit rotates limit rotation around rotary shaft 10 such that it is able to the face making grinding rod 8 different carries out contacting touching with ore sample
Hit.When central gear 12 rotates, the grinding rod 8 being connected with rotary shaft 10 and the grinding rod 8 being connected with planetary gear 9 can be made
Rotation direction contrary, when ore sample and two grinding rods 8 contact, shearing force is created to ore sample, improves and grind
Mill efficiency.
The inwall of one end of described cylinder 1 opening is provided with an annular slide track, and described annular slide track is provided with two and lacks
