Handwheel 29 and the locking plate 30 that is arranged on below base, be driven between handwheel 29 and locking plate 30 by screw spiral.This tool
Device is moved in body embodiment by universal wheel and directional wheel, it is convenient that the grains of sand after sorting are handled, and be
Make during whole device works, position is constant, avoids occurring the mixing of the separated grains of sand and the grains of sand, and ensure the safety of work
Property, locking device is additionally provided with present embodiment, including is arranged on the handwheel 29 above base and is arranged under base
The locking plate 30 of side, is driven between handwheel 29 and locking plate 30 by screw spiral.
Present embodiment further includes husky system and the well-graded grains of sand is collected, and so has using to good sorting
The grains of sand be transported through, and whole device continuous work can be made.
Operation principle：
1. shifting whole sorting unit onto operating position, rotating handwheel is grounded locking plate, is fixed in operating position；
2. small sized loader will the grains of sand be sorted, pour into the husky basket of dress, in the husky basket inner chamfer of dress and the work on wave crest inclined-plane
Under, the grains of sand to be sorted enter transmission system under the action of dead weight, by the second material transfer pipe；
3. the grains of sand to be sorted are entered in material transfer cylinder, then under the action of auger, it is passed up, and from the first material transfer pipe
Discharge reaches sub-feed tube via material transfer pipe fitting, subsequently into separation system；
4. when selecting level-one separation system, sub-feed tube position is constant, and right end is lain in vibrational system supporting support, drives
Dynamic speed regulating motor makes vibration rack setting in motion by slider-crank mechanism, drives level-one sorting sieve vibration, and sand to be sorted falls
It is online to level-one separating sieve, downward movement is obtained under its ramp structure, along with vibrational state, is formed downward along inclined-plane
Reciprocal curvilinear motion, when using level-one sorting pattern, Driving Stepping Motor rotates within the specific limits, makes steel wire rope deploying and retracting axis
Put rope and be connected to thin portion to being connected to thick portion and carry out rope closing or carry out putting rope to being connected to thin portion being connected to thick portion and receiving
The inclination angle that restrict makes level-one sort sieve to connect swing span by pulley blocks changes, and selects suitable inclination angle to make the efficiency of separation maximum
Change.When driving pulley group is to change the inclination angle of level-one sorting sieve, the second movable axis in the online supporting rack of two level separating sieve and
It is vertically moving in two level separating sieve supporting rack off the net.When using two level sorting pattern, level-one sorting work stops, point
180 ° of expects pipe swing, enables the grains of sand to be sorted to fall on two level sorting upper screen cloth, Driving Stepping Motor rotates clockwise, steel
Cord deploying and retracting axis thin portion rope closing thick portion puts rope, and when the second movable axis moves to center, continuation Driving Stepping Motor is clockwise
Rotation, steel wire rope deploying and retracting axis thin portion continue rope closing thick portion and continue to put rope, and two level separation system is drawn out, and is pulled to dominant bit
Put place, treat that sorting is husky and two level is dropped down onto by sub-feed tube sort on upper screen cloth, the grains of sand also can two level sort be formed on upper screen cloth to
Under reciprocal curvilinear motion, by two level sort upper screen cloth sorting after the grains of sand enter two level sort lower screen cloth, continue to the grains of sand
The sorting of more small dimension is carried out, then the grains of sand of big specification are from two level sorting lower screen cloth upper surface outflow, and the small dimension grains of sand are from two level
Fallen below sorting lower screen cloth, larger stone grain completes the two level to the grains of sand at this time from the upper surface outflow of two level sorting upper screen cloth
Sorting, obtains two kinds of different size of available grains of sand.Driving Stepping Motor drives steel wire rope deploying and retracting axis to be carried out to being connected to thick portion
Put rope and be connected to thin portion and carry out rope closing or put rope and be connected to thick portion and carry out rope closing to being connected to thin portion to adjust two level sorting
The angle of upper screen cloth and two level sorting lower screen cloth obtains the efficiency of separation of maximum.By suitable with fast ratio between speed regulating motor
The efficiency of separation can also be improved.
5. under level-one sorting work pattern, the well-graded grains of sand enter to fall the right half part of husky track, larger stone
Grain falls into the left-half of husky track, is then discharged out to whole device；Under two level sorting work pattern, larger stone
Grain falls into the most left half of husky track, and the small dimension grains of sand sorted fall into the middle part of husky track, and what is sorted is big
The specification grains of sand fall into the most right part position of husky track, are then discharged out to whole device.
