[0037] The inside of the reserved groove 11 is provided with an adjusting frame 15, and the adjusting frame 15 is composed of X-shaped connecting rods which are rotationally connected with each other, and the middle of each X-shaped connecting rod is rotationally connected with the driven rod 12 and the end of the adjusting rod 13.

[0040] Embodiment two:

[0041] On the basis of embodiment one, the specific working principle is as follows:

[0042] The nuts are first placed on the top of the shaking sieve frame 6 from the annular baffle at the top of the shaking sieve frame 6, at this time the motor 3 is started to drive the eccentric shaft 4 to rotate, at this time the eccentric shaft 4 will rotate in the driving groove 8, the eccentric shaft 4 is provided as an eccentric structure, at this time the eccentric shaft 4 drives the driving groove 8 to swing left and right while sliding up and down in the driving groove 8, thereby driving the shaking sieve frame 6 to swing left and right in the support box 1, thereby shaking the nuts on the top of the shaking sieve frame 6, the driven rod 12 and the adjusting rod 13 at the top of the shaking sieve frame 6 will limit the size of the nuts, the nuts larger than the distance between the driven rod 12 and the adjusting rod 13 will be discharged through the discharge chute 7, while the nuts smaller than the distance between the driven rod 12 and the adjusting rod 13 will fall between the driven rod 12 and the adjusting rod 13 to the inside of the shaking sieve frame 6, and be subjected to secondary screening through the driven rod 12 and the adjusting rod 13 at the bottom of the shaking sieve frame 6, since the density of the driven rod 12 at the bottom of the shaking sieve frame 6 is greater than that of the driven rod 12 at the top of the shaking sieve frame 6, multi-stage screening of the nuts is realized;

[0043] When nuts of different classification standards are subjected to classification treatment, it is necessary to adjust the distance between the driven rod 12 and the adjusting rod 13, the lead screw 16 is rotated under the condition that the motor 3 and the eccentric shaft 4 are stopped, since the thread directions of the two ends of the lead screw 16 are opposite, during the rotation of the lead screw 16, the lead screw 16 will drive the sliding blocks at its two ends to move towards opposite directions, when the two sliding blocks approach each other, at this time the two sliding blocks will drive the adjusting rod 13 to approach each other, and the adjusting rod 13 will compress the adjusting frame 15, so that the ends of the multiple driven rods 12 and adjusting rods 13 move synchronously, thereby adjusting the distance between the driven rod 12 and the adjusting rod 13, and realizing adjustment of the screening distance;

[0044] Since the adjusting frame 15 is composed of X-shaped connecting rods which are rotationally connected with each other, and the middle of each X-shaped connecting rod is rotationally connected with the driven rod 12 and the end of the adjusting rod 13, when a single X-shaped connecting rod is extended, at this time, every two adjacent X-shaped connecting rods will move away from each other, and the middle of the equidistantly distributed X-shaped connecting rods will move the same distance from the connection with the driven rod 12 and the adjusting rod 13, thereby synchronously adjusting the positions of the driven rod 12 and the adjusting rod 13, and achieving the adjustment of the distance between the driven rod 12 and the adjusting rod 13.

[0045] During the movement of the adjusting rod 13, at this time, the adjusting rod 13 will move away from the side of the sieve frame 6, and the adjusting rod 13 will pull the intercepting cloth 14 on the side of the lead screw 16, and the gap between the adjusting rod 13 and the lead screw 16 is sealed by the intercepting cloth 14, preventing nuts from falling between the adjusting rod 13 and the lead screw 16 and affecting the classification of nuts, when adjusting the distance between the adjusting rod 13 and the driven rod 12, at this time, the intercepting plate 10, the upper baffle 17 and the lower baffle 18 will form a temporary storage space inside the sieve frame 6, and the secondary classification of nuts is carried out in the space, when the adjusting rod 13 at the top of the sieve frame 6 and the adjusting rod 13 at the bottom of the sieve frame 6 are not on the same vertical line, at this time, the upper baffle 17 and the lower baffle 18 will rotate between the two adjusting rods 13, and the lower baffle 18 will slide inside the upper baffle 17, thereby extending the overall structure formed by the upper baffle 17 and the lower baffle 18, so as to prevent nuts from falling inside the temporary storage space formed by the intercepting plate 10, the upper baffle 17 and the lower baffle 18.
