[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] The rotary connection described in this device refers to the axial fixation of the bearing by mounting the bearing on the shaft, with a spring retaining ring groove provided on the shaft or shaft hole, and the rotation achieved by locking the elastic retaining ring in the retaining ring groove; the hinge connection refers to the connection method that allows movement through connecting parts such as hinges, pins, and short shafts.

[0018] The present invention will now be described in detail with reference to the accompanying drawings.

[0019] Example 1:

[0020] The following is combined with Figure 1-4This embodiment describes an adjustable rice vibrating sieve, comprising: a motor base 1, a motor fixed inside the motor base 1, the motor base 1 being connected to an adjustment chamber 3 via an elastic component 2, a vibrating shaft 4 being rotatably connected to the bottom wall of the adjustment chamber 3, the motor inside the motor base 1 being connected to the lower end of the vibrating shaft 4 via a flexible coupling, a cam 5 being connected to the upper end of the vibrating shaft 4, a plurality of positioning holes 6 being evenly distributed around the circumference of the cam 5, a cam 7 being coaxially provided on the upper part of the cam 5, a positioning spring 8 being connected to the inner groove of the cam 7, and the spring 8... The lower end is connected to a positioning rod 9, which can be inserted into the positioning hole 6. The upper surface of the second cam 7 is coaxially connected to a gear 10. The telescopic end of the electric cylinder 11 is rotatably connected inside the gear 10. The electric cylinder 11 is connected to the top wall of the adjustment chamber 3. After the electric cylinder 11 retracts, the gear 10 can mesh with the second gear 12. The positioning rod 9, except for the ball head at the lower end, is disengaged from the positioning hole 6. The shaft end of the second gear 12 is rotatably connected to the top wall of the adjustment chamber 3. The shaft end of the second gear 12 is connected to an adjustment rod 13. The upper part of the adjustment chamber 3 is connected to a screening mechanism 14.

[0021] During adjustment, the control cylinder 11 retracts, driving gear 10 and gear 2 12. The lower teeth of gear 2 12 have chamfers, preventing jamming during meshing. At this time, the positioning rod 9, except for the lower ball head, disengages from the positioning hole 6. Rotating the adjusting rod 13 drives gear 2 12 to rotate, which in turn drives gear 10 to rotate. Gear 10 drives cam 2 7 to rotate, and cam 2 7 drives the ball head of positioning rod 9 to slide out of the positioning hole 6. Under the action of the positioning spring 8, it slides into the next positioning hole 6. The operator judges the position of positioning rod 9 by sound and vibration of the adjusting rod 13. After adjustment, the control cylinder 11 extends, and cam 1 5 and cam 2 7 re-engage. When in use, the motor is turned on, and the motor drives the vibration shaft 4 to rotate through a flexible coupling such as a cross-slider coupling. The vibration shaft 4 drives cam 1 5 and cam 2 to rotate synchronously. The eccentric rotation of cam 1 5 and cam 2 drives the adjusting chamber 3 to vibrate. The adjusting chamber 3 drives the screening mechanism 14 to complete screening. By adjusting the relative angle of the two cams, the eccentric mass distribution is changed, thus completing the amplitude adjustment.

[0022] The elastic component 2 includes a spring plate 15 and a spring 16. The spring plate 15 is connected to the upper end of the motor base 1. The upper end of the motor base 1 and the upper surface of the spring plate 15 are both connected to the spring 16. The upper end of the spring 16 is connected to the adjustment chamber 3.

[0023] By properly arranging the positions of springs 16, stability can be maintained while preventing vibration.

[0024] 14 includes a rice sieve 141 and a bran chamber 142. The bran chamber 142 is connected to the upper surface of the regulating chamber 3. The rice sieve 141 is connected to the upper surface of the bran chamber 142. Both the rice sieve 141 and the bran chamber 142 have discharge ports 143 at their lower parts. A rotating ring 144 is rotatably connected to the outside of the discharge ports 143 of the rice sieve 141 and the bran chamber 142. The rotating ring 144 is connected to the discharge channel 145.

[0025] Rice is vibrated and screened in rice sieve 141. Bran and bran fall through the filter holes to the bottom. Rice vibrates to the edge and is discharged through discharge channel 145 at discharge port 143. Bran and bran are discharged through the lower discharge channel 145. The position of discharge channel 145 can be adjusted by rotating ring 144 to adapt to different discharge positions.
