Specific implementation mode
It is further illustrated the present invention below by embodiment, but is not limited to present disclosure.
The making step of embodiment 1, unpowered sand sifter is as follows：
（1）It uses aperture for the steel wire of 5mm, the screen drum 1 of diameter 800mm, long 2000mm is made, such as Fig. 5.
（2）3 pairs of iron hoop is made using the band steel of thickness 1.5mm, width 30mm, each pair of iron hoop is by 1 outer diameter 790mm's
The big ring of small ring and 1 internal diameter 810mm composition；Using the seamless steel pipe of diameter 80mm, wall thickness 3mm, length 3000mm as sieve
The rotary shaft 5 of cylinder；2 " rice " font supporting racks are welded in 2 small rings using the steel pipe of diameter 30mm, thickness 1mm respectively, point
It Wei not the first " rice " font supporting rack and second " rice " font supporting rack；By rotary shaft 5 respectively from the first " rice " font supporting rack 7
Passed through with the center of the second " rice " font supporting rack 8, and accordingly with the first " rice " font supporting rack 7 and second " rice " font branch
Support 8 welds together, and one first 7 center 500mm of " rice " font supporting rack is stretched out in one end of rotary shaft 5, and the other end stretches out
Second " rice " font supporting rack center 1300mm, bearing, such as Fig. 6 are installed at the both ends of rotary shaft 5 respectively.
（3）The small iron hoop that supporting rack is not set by the 3rd and 2 welding small rings of " rice " font supporting rack and rotary shaft
It packs into screen drum 1, then 3 big ring sleeves and is made that 3 pairs of big rings and small ring are corresponding respectively, clamp sieve 1 in the outer wall of screen drum；Nothing
1 pair of iron hoop of supporting rack is fixed on 1 end of screen drum, has welded the second " rice " font supporting rack 9 and rotary shaft 5 is stretched out
The iron hoop of " rice " font supporting rack center 500mm is fixed on other 1 end of screen drum, then passes through welding, riveting or bolt
Fixed mode makes 3 pairs of iron hoops clamp screen drum 1, such as Fig. 7.
（4）Use the L-type angle steel that 7 thickness are 600mm for 3mm, length（60mm×40mm）As lifting blade 2, every
The shape of lifting blade 2 is as shown in Figure 8.
（5）By 2 leptoprosopy of lifting blade（The face of 40mm wide）Both ends, be adjacent to respectively and in the small iron hoop that is welded in screen drum 1
On wall；7 lifting blades 2 are evenly distributed on the circumference of inboard wall of riddle drum, and every lifting blade 2 is allowed to be formed with rotary shaft 5 centainly
Angle, such as Fig. 9.
（6）Using angle steel or channel steel, 2 trapezoid supports are welded, the trapezoid support is respectively the first shaft supporting frame 6 and
Two shaft supporting frames 7 are respectively used to the both ends of support rotary shaft, distinguish installation axle in the centre position of 2 trapezoid support upper beams
Bearing designs the difference in height of the first shaft supporting frame 6 and the second shaft supporting frame 7 so that rotary shaft according to the distance of two supporting points
5 and horizontal angle are 15 °, such as Figure 10.
（7）Using the steel plate after 1.5mm, it is welded the fine sand receiving hopper 3 of inverted trapezoidal, is opened wide up and down, and two end faces
Closing, in the lower cone outlet of fine sand receiving hopper 3, close to the lower end of screen drum 1, one piece of U-typed sliding slot of welding, as coarse sand and piece
Shape particle splicing groove 4, such as Figure 11 and Figure 12.
（8）By two end faces of coarse sand and sheet-like particle splicing groove 4 respectively with the first shaft supporting frame 6 and the second shaft supporting frame
7 welding or bolt are fixed, and then weld the first shaft supporting frame 6 and the second shaft supporting frame 7 with square steel, is fixed, finally will connection
The bearing of the rotating shaft terminal of screen drum distinguishes security protection in the bearing block of height pedestal upper end, and fog-spray nozzle 10 individually uses holder
It is fixed on the top of 1 feed inlet of screen drum, just completes the making of apparatus of the present invention, such as Fig. 4.
（9）When using the sand sifter, by the oblique upper end entrance for stretching into screen drum 1 of the discharge port of raw sand belt feeder 12,
And it is directed at the side inner wall of screen drum, the impulse force of sand is assigned using the gravity and fine sand belt feeder 12 for the sand for entering screen drum to drive sieve
Cylinder 1 rotates, to complete the screening processing to sand.When using manually into sand, the oblique side wall for being thrown into screen drum of sand is equally allowed, profit
Screen drum rotation is driven with the dead weight of sand, completes sieve sand work.
Implementation result：
The device is not due to needing dynamical system, so own wt is greatly reduced, convenient for arbitrarily being moved in sand field；Simultaneously
Without considering power issue, the applicable situation of the device is also significantly increased.
