Specific embodiment
The present invention will be further described with reference to the accompanying drawings and examples:
As shown in Figure 1, rock sample grinding mechanism described in the utility model, including roller 1, shaft 2, support 3 and solid
Dead axle 4；The roller 1 includes horizontally disposed cylinder 11 and the cover 12 for being fixed on 11 both ends of cylinder；Outside each cover 12
There is shaft 2 on surface along 11 axial restraint of cylinder；The shaft 2 is rotatably installed on support 3；Charging is provided on the cylinder 11
Mouth 13；Dismountable lid 14 is provided at the feed inlet 13；The fixing axle 4 is mounted in cylinder 11 and fixing axle 4 is flat
Row is arranged in the axis of cylinder 11；Several overturning blades 5 are provided in the fixing axle 4.
The cylinder 11 is cylindrical structure, the axis coaxle setting of the axis of the cylinder 11 and two shafts 2.It is described
Shaft 2 is rotatably installed on support 3, keeps shaft 2 rotatable around its axis.The fixing axle 4 can be fixed on by connector
On 11 inner wall of cylinder, preferably, corresponding cover 12 is fixedly connected respectively at the both ends of the fixing axle 4.
The working principle of rock sample grinding mechanism described in the utility model is as follows: being 400mm with internal diameter, length is
For the cylinder 11 of 600mm, lid 14 is opened, will be put into roller 1 by pretreated rock fragment from feed inlet 13, so
Multiple mill balls are put into roller 1 from feed inlet 13 again afterwards, the mill ball is steel ball, and the size of mill ball can be identical,
It can also be different, as a preferred embodiment, the mill ball includes: that two mill balls, the diameters that diameter is 40mm are 30mm's
Three mill balls, three that diameter is 20mm mill ball, two mill balls that diameter is 10mm.Feed inlet is closed by lid 14
13；Roller 1 is rotated, mill ball grinds rock fragment in roller 1, and after the completion of grinding, roller 1 stops operating；It opens
Feed inlet 13 is turned to the bottom of roller 1 by lid 14, and the sample and mill ball after grinding freely fall into ready charging tray
In；The mill ball in charging tray is taken out, next time, test was spare, and it is 0.6mm that the rock powder sample after grinding is passed through screen size first
Testing sieve after, screen out partial size be greater than 0.6mm thick rock particles；It then is 0.315mm's sample is passed through screen size
Testing sieve obtains required test rock powder sample.
The rock sample grinding mechanism of the utility model, structure is simple, easy to operate, and grinding uniformly, can significantly improve rock
The quality of powder avoids the waste of rock sample.By controlling the velocity of rotation of roller 1, mill ball can be made to pass through in roller 1
Freely falling body is pounded to rock fragment, using the impact force fractured rock fragment of mill ball, between broken rock fragment, rock
Between 1 inner wall of fragment and roller and the mutual downthrust between rock fragment and mill ball grinds rock fragment further
Mill, to obtain the smaller sample of partial size.
By setting fixing axle 4 and overturning blade 5, roller 1 during rotation, drives overturning blade 5 to rotate, overturns leaf
Piece 5 can be recycled in the lower position in roller 1 and between higher position.When overturning blade 5 turn to it is minimum in cylinder 11
When position, roller 1 is continued to rotate, and partial mill ball and/or rock fragment are promoted to cylinder by the overturning blade 5 of extreme lower position
Higher position in body 11 makes mill ball and/or rock fragment freely falling body under the effect of gravity, and then pounds to rock fragment,
The mutual effect of impact between mill ball and rock fragment is further improved, grinding efficiency is improved, saves test period,
It improves work efficiency.
The fixing axle 4 can be arranged with the axis coaxle of cylinder 11.In order to further increase grinding efficiency, as preferred
Scheme, the fixing axle 4 are eccentrically set in cylinder 11.Bias between the axis of the fixing axle 4 and the axis of cylinder 11
Away from according to be packed into the size of cylinder 11 and cylinder 11 rock fragment number determine.
At least one set of overturning blade 5 can be fixed in the fixing axle 4, the quantity of every group of overturning blade 5 is at least one,
When the quantity of every group of overturning blade 5 is multiple, multiple overturning blades 5 are uniformly arranged along the circumferential direction of fixing axle 4.Preferably,
The overturning blade 5 is spirally distributed along the axial direction of fixing axle 4.The length direction of each overturning blade 5 can be perpendicular to solid
The length direction of the axial setting of dead axle 4, the overturning blade 5 can also be inclined to set with the axial direction of fixing axle 4.
For convenience of operation, the end of one of shaft 2 is fixed with manual rocker 6.In use, only needing rotation manual rocking bar
6, roller 1 can be driven to rotate by shaft 2.
The support 3 includes pedestal 31 and two brackets 32 being fixed on pedestal 31 side by side；Two shafts 2 rotate respectively
It is mounted on bracket 32.The pedestal 31 can be frame structure, be also possible to steel plate, by the way that pedestal 31 is arranged, increase bottom
The contact surface of seat 31 and ground, increases the stability of whole device.
In order to improve the flexibility of operation, crude test sieve 7 is additionally provided between the pedestal 31 and roller 1.The thick examination
Sieve 7 is tested to be removably mounted on bracket 32 or on pedestal 31.The screen size of the crude test sieve 7 is 0.5~0.7mm, is made
To be preferred, the screen size of crude test sieve 7 is 0.6mm.Further, it is additionally provided between the pedestal 31 and crude test sieve 7 thin
Testing sieve 8.The thin testing sieve 8 is removably mounted on bracket 32 or on pedestal 31.The screen size of the thin testing sieve 8
For 0.25~0.35mm, preferably, the screen size of thin testing sieve 8 is 0.315mm.
After the completion of rock sample is ground by roller 1, lid 14 is opened, feed inlet 13 is turned to the bottom of roller 1,
Sample and mill ball after grinding are freely fallen on crude test sieve 7, and the thin testing sieve 8 that passes through again along powder after screening is screened,
Final test rock powder sample, which is freely fallen into ready charging tray, to be collected.After screening, by crude test sieve 7 and thin examination
It tests sieve 8 to remove from bracket 32 or pedestal 31 respectively, remove after remaining in the bulky grain rock on testing sieve, then crude test is sieved
7 and thin testing sieve 8 be mounted on bracket 32 or pedestal 31.
