According to the invention, the screw 308 is rotated according to the batch of duck necks, so that the moving block 307 slides in the material hole 305 to adjust the length of the duck necks which can be placed in the material hole 305, the situation that the duck necks are easy to spill during cutting due to an overlarge gap between the material hole 305 and the duck necks can be prevented, two material frames are respectively placed at one ends, far away from the fixed cylinder 101, of the top-layer screening frame 201 and the bottom-layer screening frame 201, the duck necks are placed in the material hole 305 on the turntable 304, and the rotating block 111 and the first transmission shaft 117 are driven to rotate by the motor 110;

the rotating block 111 rotates to drive the rectangular column 112 and the limiting column 113 to rotate, when the limiting column 113 moves to a sliding hole on the grooved pulley 105, the rectangular column 112 is used for compressing the second spring 114 and the limiting rod 115 to slide into the limiting cylinder 116, so that the limiting column 113 can slide into the sliding hole on the grooved pulley 105 and can drive the grooved pulley 105 to intermittently rotate, the grooved pulley 105 intermittently rotates to drive the central shaft 103 to intermittently rotate, the central shaft 103 is limited to rotate by meshing of the pawl 107 and the ratchet 106, the central shaft 103 intermittently rotates to drive the turntable 304 to intermittently rotate, so that the material hole 305 with the duck necks on the turntable 304 moves to the position below the blade 404, the air cylinder 402 is used for driving the rectangular block 403 and the blade 404 to descend, the blade 404 is inserted into the knife hole 306 to cut and separate the duck necks, the air cylinder 402 returns to the position after cutting, the blade 404 leaves the knife hole 306, and the cut duck necks move to the blanking hole 302 under the rotation of the turntable 304, enabling the duck necks to fall onto the screen plate 202 in the screening frame 201 at the top layer through the blanking holes 302 and the blanking channel 303;

utilize hold-in range 120 cover to locate on synchronizing wheel 119 on first transmission shaft 117 and the second transmission shaft 215, make first transmission shaft 117 rotate and drive second transmission shaft 215 and rotate, second transmission shaft 215 rotates and drives two worms 214 and rotate, worm 214 rotates and drives worm wheel 213 and rotates, worm wheel 213 rotates and drives axis of rotation 211 and rotate, axis of rotation 211 rotates and drives the rocking arm 209 rotation at its both ends, rocking arm 209 rotates and drives skew pole 208 skew, the dead lever 207 skew that the other end of skew pole 208 rotated the connection offsets thereupon, dead lever 207 skew drives screening frame 201 one end skew, cooperate elastic steel plate 205 again, make two screening frames 201 can carry out the skew vibrations simultaneously, shake the screening with the duck neck on the otter board 202 of top layer, make the duck neck piece that the cutting produced fall into on the inside bottom plate 203 of screening frame 201 of bottom, and transport the duck neck and piece after the screening to inside the material frame.

It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
