Embodiment 1：
As shown in Figs. 1-3, a kind of sand sieving machine, including scalping device, transmission device and dusting cover device, transmission device respectively with
Scalping device is connected with dusting cover device, and the dusting cover device includes dusting cover rack 15, first reducing motors 13, first reducing motors
Holder 16, rotary screen 10, drum shaft 12 and supporting rack 11, the dusting cover rack 15 are fixed on ground, dusting cover rack 15
Top be bolted rotary screen 10 and supporting rack 11 be installed, 10 slant setting of rotary screen；Drum shaft 12 is mounted on rolling
The centre of shaft screen 10, one end are fixed by supporting rack 11, and the other end is connect by shaft coupling with first reducing motors 13, and first subtracts
Speed motor 13 is mounted on by bolt on first reducing motors holder 16, and first reducing motors holder 16 is bolted on carefully
In screen frame 15.
The scalping device includes scalping rack 1 and feed hopper 2, and feed hopper 2 is mounted in scalping rack 1, feed hopper 2
Lower section is equipped with drain spout 20, and the feed inlet 21 of the feed hopper 2 is to be obliquely installed, and the filtering of parallel installation is equipped at feed inlet 21
Roller 4, the filtering roller 4 are welded on feed hopper 2；The side of the feed hopper 2 is equipped with vibrating motor 5, and the vibrating motor 5 is logical
It crosses and is bolted on the lower right outer housing of feed hopper 2.The transmission device includes conveyer belt mounting bracket 19, second subtracts
Speed motor 8, second reducing motors holder 7, belt pulley 9 and conveyer belt 6, the conveyer belt mounting bracket 19 tilt installation, lowermost end
On the ground, top is equipped with the drain spout 20 of feed hopper 2, and most significant end is fixed by dusting cover rack 15, and conveyer belt for installation
Sliding plate 18 at one are installed immediately below the highest point of mounting bracket 19, rolling is dumped in for conveyer belt 6 to be caught the sand come
In shaft screen 10；The second reducing motors 8 are bolted on second reducing motors holder 7, second reducing motors
Holder 7 is welded on conveyer belt mounting bracket 19, and the second reducing motors 8 are sequentially connected by transition wheel 17 and belt pulley 9；It passes
Band 6 is sent to be laid on conveyer belt mounting bracket 19；Belt pulley 9 is equipped at two and is separately mounted to the both ends of conveyer belt 6, belt pulley 9
It is sequentially connected with conveyer belt 6.The quantity of the filtering roller 4 is ten to 30, every filtering the distance between roller 4 for 5~
12cm；The general water content of sand is larger, and when sand is passed through sieve, sand is easy to unite, and is not easy to disperse, and easily sticks and sieving
On the net, screening effect is influenced, therefore is first filtered one time with filtering roller 4, the sand of adhesion can also be smashed, standard is carried out for dusting cover
Standby work, increases the working efficiency of dusting cover.
The bottom that the rotary screen 10 is obliquely installed is equipped with waste sliding plate 14 at one by bolt, cannot penetrate roller
The waste materials such as the larger stone of sieve 10 are fallen by waste sliding plate 14 on one side far from fine sand；The rotary screen 10 and ground it
Between inclined angle be δ, the value range of δ is to be less than 30 °, the larger stone etc. if inclined angle is too small more than 5 °
Waste material cannot slide ground out of rotary screen 10, and fine sand also has little time the rotary screen rotated 10 if inclined angle is too big
Screening just slides ground with larger stone, reduces the screening rate of fine sand.
Angle between the feed inlet 21 and horizontal plane isValue range be more than or equal to 30 °, be less than or equal to
60°；The both ends of the feed inlet 21 of the feed hopper 2 are respectively equipped with baffle 3 at one by bolt, can avoid forklift to feed hopper 2
The when of falling sand, is poured on conveyer belt 6；The lower section of drain spout 20 is welded with Antileaking plate 22, and the sand that top is got off can be prevented to fall
The waste of sand is caused in the outside of conveyer belt 6, avoids manually scooping up again and tidy up；It is also solid by bracing ring 23 in rotary screen 10
It is fixed, it is flattened by sand when preventing rotary screen 10 from rotating.
The operation principle of the present invention is that：
Sand is poured on feed inlet 21 by forklift first, then sand by filtering roller 4 between gap fall into
In hopper 2, and larger stone then cannot pass through filtering roller 4 between gap, thus be retained in filtering roller 4 on, due into
Material mouth slant setting, thus the waste materials such as larger stone directly slide on the ground, complete scalping work；And enter feed hopper 2
Interior sand is fallen by drain spout 20 on conveyer belt 6, and sand is transported in rotary screen 10 by communicated band 6 and sliding plate 18,
Under the action of first reducing motors 13 drive drum shaft 12 to rotate, the fine sand in rotary screen 10 is screened the reception for falling into ground
On device, due to rotary screen 10 and ground inclination certain angle, thus the work that the waste materials such as larger stone are rotated in rotary screen 10
It is gradually slid to the lower end of rotary screen 10 with lower, is finally slid in the side far from fine sand along waste sliding plate 14, completed thin
Riddler makees.
Wherein vibrating motor 5 can play effect of vibration to sticking in the sand on 2 inner wall of feed hopper, will stick in feed hopper 2
Sand on inner wall, which shakes, to be fallen on conveyer belt 6.
Vibrating motor 5 is HY series alloys vibrating motors, and model TB-0.28, power 50W, vibration force is
70KG。
First reducing motors 13 and second reducing motors 8 are the horizontal series three phase toothed gearing electric motors of GH, model
GH-22-200-60-S-B, force-output shaft 22mm, reduction ratio 1:60.
