Description
Technical field
The utility model is related to sandstone manufacture field, more particularly, to a kind of adjustable sandstone sieve of particle diameter.
Background technology
The state that sandstone is present in nature is the admixture of sand grains and rubble, in the industrial production, it is necessary to by difference
The sand grains and rubble of particle diameter are separated, in order to production and application., it is necessary to by one especially in the manufacturing process of the materials such as concrete
Determine particle size sand grains and rubble mixing again together, make to meet the sand grains that coagulation soil class matches somebody with somebody and combined with rubble, to determine difference
The concrete of strength grade.It is then desired to the sandstone raw material of collection, be screened by screen cloth, to select different-grain diameter
Sandstone specification, existing screen cloth uses fixed grit mesh number, and the sandstone of sieve different meshes needs to change the screen cloth of different meshes, behaviour
Make complicated, inefficiency.Therefore, it is necessary to design a kind of adjustable sandstone sieve of particle diameter.
Utility model content
The utility model provides a kind of adjustable sandstone sieve of particle diameter, and screen frame automatic sand screening can be driven by eccentric wheel, and
Can manual adjustable screen particle diameter, sift out the sandstone of different-grain diameter.
To achieve these goals, the utility model is to realize by the following technical solutions：A kind of particle diameter is adjustable
Sandstone sieve, including support, screen frame and screen cloth, the screen frame are provided with two ends in the middle part of connecting rod, the connecting rod and are respectively equipped with fixture block,
The fixture block is by the fixing groove in spring connecting bracket, and the support also includes the eccentric wheel driven by motor, the bias
Wheel is provided with the leash for being additionally provided with driving lever, the support and bypassing follower lever connection driving lever and connecting rod two ends.
Further, the screen cloth includes several transverse and longitudinals grating arranged in a crossed manner, the grating point of horizontal and longitudinal direction
Not into two layers of setting, the grating two ends connect screen frame by rotating shaft respectively, and the rotating shaft is hinged one end of L-type adjusting rod, often
The other end of the individual adjusting rod is hinged same guide rod, and the guide rod extends to screen frame edge, and in the edge
One end is provided with the insertion conduit of radian in 90 °, and the guide rod coordinates locking by lock screw with screen frame through insertion conduit.
Further, when the grating rotates regulation by guide rod, the adjustable distance of the grating each other is
0.03mm-8mm。
Further, between the grating adjustable distance and the rotation radian of guide rod matches, and in through slot
The edge in road is provided with matching graduation mark.
The beneficial effects of the utility model are：
The utility model can manually be adjusted to the spacing between the grating of screen cloth, so that between changing between grating
Away from by adjusting the distance between radian and screen cloth ratio, the spacing distance formation for setting corresponding radian to adjust with grating is adjusted
Scale is saved, the manual regulation in screen cloth is realized, easy to operate, using effect is good.
Brief description of the drawings
Fig. 1 is one structural representation of the utility model；
Fig. 2 is a structural representation of the utility model screen frame part；
As shown in FIG.：1- supports, 2- screen frames, 3- screen clothes, 11- eccentric wheels, 12- leashes, 21- connecting rods, 22- cards
Block, 23- adjusting rods, 24- guide rods, 25- insertions conduit, 31- gratings.
Embodiment
In order that those skilled in the art more fully understand the technical scheme in the utility model embodiment, and make this reality
Can be more obvious understandable with the above-mentioned purpose of new embodiment, feature and advantage, it is real to the utility model below in conjunction with the accompanying drawings
Technical scheme in example is applied to be described in further detail.
As illustrated, a kind of adjustable sandstone sieve of particle diameter of the utility model, including support 1, screen frame 2 and screen cloth 3, screen frame 1
Bottom be used for fixed connecting rod 21 provided with one, the middle part two ends of connecting rod 21 are respectively equipped with fixture block 22, and fixture block 22 passes through bullet
Fixing groove in spring connecting bracket, support 1 also includes the eccentric wheel 11 driven by motor, and eccentric wheel 11 is provided with driving lever, branch
The leash 12 for bypassing follower lever connection driving lever and connecting rod two ends is additionally provided with frame 1.Eccentric wheel 11 on support 1 is rotated,
Leash 12 is driven to force connecting rod 21 and screen frame 2 to be swung back and forth, because fixture block 22 and spring assembly make connecting rod 21
Connected with support 1, connecting rod 21, by spring and the mating reaction of fixture block 22, follows eccentric wheel 11 to move, screen frame while swinging
2 form the active force of screening sandstone in the presence of the oscillatory forces, and corresponding particle diameter sand grains is sifted out from screen cloth.
As an improvement, screen cloth includes several transverse and longitudinals grating 31 arranged in a crossed manner, the grating 31 of horizontal and longitudinal direction respectively into
Two layers of setting, the two ends of grating 31 connect screen frame 2 by rotating shaft respectively, and rotating shaft is hinged one end of L-type adjusting rod 23, each adjusting rod
23 other end is hinged same guide rod 24, and guide rod 24 extends to the edge of screen frame 2, and is provided with into one end of the edge
The insertion conduit 25 of 90 ° of radians, guide rod 24 coordinates locking by lock screw with screen frame 2 through insertion conduit.Guide rod 24
Each grating 31 can be adjusted by the rotation of arc by adjusting rod 23 rotate, grating 31 after rotation, each grating 31 it
Between spacing can change, because the distance between grating 31 is smaller, and distance therebetween can look at that sandstone passes through away from
From as sandstone screens required mesh number, after corresponding mesh number is regulated, is directed to bar 24 and is locked at by lock screw
On screen frame, the distance between grating 31 is fixed.
Preferably, when grating 31 rotates regulation by guide rod 24, the adjustable distance of grating 31 each other is
0.03mm-8mm.Common sandstone specification is 3-400 mesh, and 3-400 purposes substantially aperture is 6.2mm-0.03mm, therefore by dividing
Horizontal and vertical grating 31 is not adjusted, and formation 0.03mm-8mm meets existing for the rectangular opening on side between enabling each grating 31
Most sandstones screening on the market is required.
Further improve, the adjustable distance and the rotation radian of guide rod 24 between grating 31 match, and in insertion
The edge of conduit 25 is provided with matching graduation mark.Grating 31 is rectangle or circular arc type, in the rotation process by guide rod, grating 31
The distance between due to being a millimeter rank, can myopia look at the distance between grating 31 for grating 31 close to one end perpendicular to number
The horizontal range that value is put, because the ultimate range between grating 31 is rotated to the guide rod that is adjusted between minimum range
0 ° -90 °, therefore, matching graduation mark can myopia look at be 0 ° -90 ° be 0.03mm-8mm secondary linear function, matching carve
Corresponding mesh number or range marker can be set according to the number of degrees of rotation by spending line, and set 1-8mm integer graduation mark, be carried out strong
Adjust mark, during in order to adjust, more convenient operation.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent substitution, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
