Technical field
The utility model relates to ore screening field of mechanical technique, specially a kind of ore screening machine.
Background technique
Ore is generally made of ore mineral and gangue mineral.Ore mineral refers to the metal that can be utilized in ore or non-
Metalliferous mineral, also referred to as valuable mineral.Chalcopyrite, bornite, vitreous copper and peacock such as the chromite in chrome ore, in Copper Ores
Stone, the asbestos etc. in asbestos ore.Gangue mineral refers to those and ore mineral phase association, temporary unavailable mineral,
Claim useless mineral.Such as olivine, the pyroxene in chrome ore, quartz, sericite, chlorite in Copper Ores, in asbestos ore
Dolomite and calcite etc..Gangue mineral is mainly nonmetallic mineral, but also includes some metalliferous minerals, as contained pole in Copper Ores
A small amount of galena, zincblende, because of no comprehensive utilization value, also referred to as gangue mineral.Contained ore mineral and gangue mineral in ore
Deal ratio, it is different with different metal ore.Also there is difference with the rich or poor grade difference of ore in same ore.In many
In metallic ore, the deal of gangue mineral is often considerably beyond the deal of ore mineral.Therefore, ore is before smelting, must be through
Ore dressing could smelt after discarding most of useless material.
The ore that ore screening machine is used to filter out similar size before ore refinement facilitates refinement, deposits currently on the market
In the ore screening machine of larger type, one kind is tilted-putted big sieve nest, and ore tumbles downwards from upper end, lesser ore from
Sieve pore leaks down, and this kind of screening machine has a problem that: sieve nest is motionless, and there is part will not the size ore smaller than sieve pore
Leak down from sieve pore, screening effect is bad, and another kind of is the horizontal positioned reciprocating sieve of sieve nest, and sieve nest high frequency is needed during screening
The swing of rate, because ore is heavier, energy consumption is very big, and ore is easy to break machine.
Utility model content
The purpose of this utility model is to provide a kind of ore screening machines, to solve mentioned above in the background art ask
Topic.
To achieve the above object, the utility model provides the following technical solutions: a kind of ore screening machine, including pedestal, institute
It states and hydraulic cylinder is installed on pedestal, the hydraulic cylinder is equipped with the push rod with circular hole, and the push rod is living by pin and second support

In figure: 1 pedestal, 2 hydraulic cylinders, 3 push rods, 4 first supports, 5 racks, 6 second supports, 7 double-layer cylinder screens, 8 centers
Axis, 9 spokes, 10 first screen drums, 11 second screen drums, 12 sprocket wheels, 13 chains, 14 motors, 15 feed hoppers, 16 discharge nozzles.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of ore screening machine, including pedestal 1, it is described
Hydraulic cylinder 2 is installed, the hydraulic cylinder 2 is equipped with the push rod 3 with circular hole, and the push rod 3 passes through pin and second support on pedestal 1
6 are flexibly connected, and the second support 6 is set to the lower section of rack 5, are equipped with double-layer cylinder screen 7, the bilayer in the rack 5
The center of drum sieve (7) is equipped with central axis 8, and the central axis 8 is circumferentially with spoke 9, and the spoke 9 is equipped with the first screen drum
10 and second screen drum 11, the left end of the central axis 8 sprocket wheel 12 is installed, the sprocket wheel 12 is connected to motor 14 by chain 13
Output end, the motor 14 is mounted in rack 5, and the left end of the rack 5 is equipped with feed hopper 15, the right side of the rack 5
End is equipped with discharge nozzle 16.
Specifically, being equipped with first support 4 on the pedestal 1, the first support 4 passes through 6 activity of pin and second support
Connection, the second support 6 can be rotated relative to first support 4.
Specifically, the sieve pore on first screen drum 10 is bigger than the second screen drum 11, smaller ore can be with the first screen drum 10
Fall into the second screen drum 11.
Specifically, being flexibly connected between the central axis 8 and rack 5 by bearing, the double-layer cylinder screen 7 can be opposite
Rack 5 moves in a circle.
Specifically, the lower end discharge port of the feed hopper 15 accesses in the first screen drum 10.
Specifically, the left end of three discharge nozzles 16 is sequentially located at the first screen drum 10, the second screen drum 11, double from top to bottom
The lower section of the outer wall of layer drum sieve 7, the ore screened are discharged from right end by respectively corresponding to discharge nozzle 16.
Working principle: jacking up the push rod 3 of hydraulic cylinder 2 when use upwards, so that the left side of rack 5 is more slightly higher than the right, so
Start motor 14 afterwards, motor 14 is rotated by chain 13 with movable sprocket 12, so that double-layer cylinder screen 7 rotates, into feed hopper 15
It is packed into ore not of uniform size, ore enters in the first screen drum 10 from the lower end discharge port of feed hopper 15, and ore is with the first screen drum
10 rotation and roll, the ore smaller than the screen size of the first screen drum 10 can be dropped into the second screen drum 11, because entire double-deck
Drum sieve 7 be it is inclined, i.e., left end is higher than right end, therefore ore is to slide slowly to right end in drum sieve, until slide into
Then right end is distinguished discharge nozzle 16 corresponding from below and is discharged.By primary screening can separate three kinds it is various sizes of
Ore, different ores is different from the coefficient of friction of screen drum, so ore is different to right end sliding condition in screen drum, Yong Huke
The tilt angle of double-layer cylinder screen 7 is adjusted to adjust the height of push rod 3 according to the actual situation.
In the present invention unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " Gu
