Operation principle：In use, the present invention is moved to desired zone by operating personnel, then poured into the first screening plant
Suitable sand starts knocking device operation, and knocking device taps the screening part of the first screening plant, to be carried out to sand
Screening, the sand of smaller particle drop down onto on hopper, and are fallen from hopper through the first opening, and the sand of larger particles stays in first
In screening plant, after the completion of screening, close knocking device, and rotate the first screening plant, to by the first screening plant compared with
The sand of bulky grain swings to right of the present invention, is then rotating the first screening plant, the first screening plant is made to reset, so
Sand is screened.
Because the first screening plant includes flap, riser, the first spring, the first screening frame and handle, set above transverse slat
There is a flap, the top of flap right end and rightmost support is articulated and connected, and the second opening, top of flap or so are provided in the middle part of flap
Both sides are respectively connected with riser, and the second opening is respectively connected with the first spring, both sides between the riser of left and right on the inside of the riser of both sides
The first screening frame is connected between first spring, the first screening frame is located at right over hopper, and the top left side of flap is connected with handle
Hand, handle are located on the left of riser.So operating personnel pour into suitable sand in the first screening frame, start knocking device pair
First screening frame bottom is tapped, and under the action of the first spring, the first screening frame is shaken up and down so that the first screening plant
Sand is screened, it is sustainable that sand is added in the first screening frame during use, sand can so be carried out continuous
The sand of screening, smaller particle is fallen from hopper through the first opening, and the sand of larger particles stays in the first screening frame, screening
After the completion, knocking device is closed, flap is then rotated clockwise by handle, to drive the first screening frame to rotate clockwise,
And then swing to the sand in the first screening frame on the right side of the present invention, after the sand in the first screening frame is poured out completely, when another mistake
Needle rotates flap so that the first screening frame resets.
Because knocking device includes motor, first rotating shaft, first bearing seat, second spring and steel ball, leftmost support
Right upper portion is equipped with motor, and the output shaft of motor is connected with first rotating shaft, and first rotating shaft slidingtype runs through the left and right two of hopper
The left upper portion of upper lateral part, rightmost support is equipped with first bearing seat, and first rotating shaft connects with the bearing interference in first bearing seat
It connects, the middle part uniform intervals of first rotating shaft are connected with second spring, and second spring is located in hopper, the end connection of second spring
There are steel ball, steel ball and the first screening frame to coordinate.So starting motor rotation, motor drives first rotating shaft rotation, to pass through the
Two springs drive steel ball rotation, steel ball tap first screening frame bottom so that the first screening frame up and down shake, you can to sand into
Row screening closes motor after the completion.
Because further including having the second screening plant, the second screening plant include mounting rod, second bearing seat, second turn
Axis, bevel gear, disk, support plate, guide rod, the second screening frame and first connecting rod, the right side central of leftmost support are connected with mounting rod,

Bar 98, guide rod 98 coordinate with guide hole 97, are connected with the second screening frame 99 between both sides guide rod 98, the second screening frame 99 is located at hopper
6 and first are open between 3, and the bottom eccentric position of disk 95 is hingedly connected with first connecting rod 910, the right end of first connecting rod 910
It is articulated and connected with 99 left upper portion of the second screening frame.So sand drops down onto the second sieve after the screening of the first screening frame 75 from hopper 6
It selects in frame 99, the rotation of first rotating shaft 82 drives the rotation of the second shaft 93 by bevel gear 94, to drive disk 95 to rotate, in turn
The second screening frame 99 is driven to move left and right by first connecting rod 910, the second screening frame 99 is moved left and right carries out secondary sieve to sand
Choosing is good to improve screening efficiency, screening effect.
Because further including having montant 10, baffle 11, block 12 and third spring 13, the top of leftmost support 4 is connected with perpendicular
Bar 10,10 outside slidingtype of montant are equipped with baffle 11, and the top of montant 10 is connected with block 12, connects between baffle 11 and block 12
It is connected to third spring 13, montant 10 passes through third spring 13.It is therefore desirable to when rotating flap 71, turn left baffle 11 so that
Baffle 11 is detached with flap 71, you can and rotation flap 71 outwells the sand in the first screening frame 75, after flap 71 is resetted, to
Upper pulling baffle 11, third spring 13 is compressed, and then turn right baffle 11 so that baffle 11 is located at 71 top of flap, so
Baffle 11 is unclamped afterwards, and under the action of third spring 13,71 clamping of flap so can be prevented knocking device 8 right by baffle 11
First screening frame 75 causes flap 71 to be shaken when tapping, to improve the stability of the present invention, further increase sand screening effect
Rate.
Because further including having second connecting rod 14, cross bar 15 and driving lever 16, second is respectively connected at left and right sides of the bottom of hopper 6
The bottom of connecting rod 14, both sides second connecting rod 14 is respectively connected with cross bar 15, and the bottom uniform intervals of cross bar 15 are connected with driving lever 16, dials
Bar 16 is contacted with bottom in the second screening frame 99.So the second screening frame 99 moves left and right so that driving lever 16 is to the second screening frame
Sand in 99 is stirred, to further improve screening efficiency.
The preferred embodiment of the present invention above described embodiment only expresses, the description thereof is more specific and detailed, but simultaneously
Cannot the limitation to the scope of the claims of the present invention therefore be interpreted as.It should be pointed out that for those of ordinary skill in the art
For, without departing from the inventive concept of the premise, several deformations can also be made, improves and substitutes, these belong to this hair
Bright protection domain.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
