A residual material recovery component is arranged opposite to the residual material recovery component, which includes a support seat 9 fixedly connected to the opposite side walls of the two support piles 3, and vibration motors 10 are placed on the upper ends of the left and right sides of the support seat 9. The vibration motor 10 cooperates with the machine body 1 to drive a number of screen plates 7 to vibrate reciprocatingly under the elastic force of the first spring 20 and the second spring 23.

[0024] A plurality of relatively rectangular openings 6 are provided on the inner walls on the left and right sides of the cavity 2, and a sieve plate 7 is horizontally inserted between the two rectangular openings 6. The sieve holes of the plurality of sieve plates 7 are arranged in descending order from top to bottom. Discharge chutes 12 are fixedly connected to the side walls at both ends of the left and right sides of the plurality of sieve plates 7. The discharge chute 12 is used to discharge the screened sugar retained on the sieve plate 7. Positioning blocks 13 are fixedly connected to the side walls at both ends of the front and rear ends near the four corners of the plurality of sieve plates 7. The upper ends of the limit rods 8 are movable through the plurality of positioning blocks 13 arranged in the same vertical direction. The upper ends of the plurality of sieve plates 7 near the front and rear sides are fixedly connected with limited baffles 14. The two limited baffles 14 are arranged opposite to the discharge chutes 12 on both sides. The limited baffles 14 ensure that the sugar is always on the upper end surface of the sieve plate 7 and will not fall into the gap between the sieve plate 7 and the cavity 2.

A slider 18 is fixedly connected to the side wall of the rectangular baffle plate 16 away from the machine body 1, and the slider 18 is arranged close to the upper end of the rectangular baffle plate 16. A slide block 18 is arranged on the side wall of the rectangular cover body 15 facing the machine body 1. The matching slide groove 19 and the slider 18 move in the slide groove 19, which facilitates the rectangular baffle 16 to move in the rectangular cover body 15, and at the same time limits the movement of the rectangular baffle 16 so that it can only move close to the rectangular opening 6, to avoid the rectangular baffle 16 and the rectangular opening 6 being misaligned, resulting in the unscreened sugar spilling out of the rectangular opening 6. The bottom of the slide groove 19 is connected to the lower end of the rectangular cover body 15, and a plurality of first springs 20 are fixedly connected to the top surface of the rectangular cover body 15. The lower ends of the plurality of first springs 20 are fixedly connected to the upper end of the rectangular baffle 16. The elastic properties of the plurality of first springs 20 ensure that the lower end of the rectangular baffle 16 is always in contact with the upper end of the sieve plate 7. The rectangular baffle 16 can be separated from the sieve plate 7 only when and only when the handle 17 is pulled.

[0026] A limiting rod 8 is provided at one end of the body 1 near the four corners, and the four limiting rods 8 are all arranged in association with a plurality of sieve plates 7.

[0027] When the utility model is in use, the sieve plate 7 with the smallest aperture is first passed through the lowermost horizontally opposite rectangular opening 6, the four limiting rods 8 are passed through the four positioning blocks 13 on the sieve plate 7 and are threadedly connected to the threaded holder 22 on the support block 21, the second spring 23 is sleeved on the limiting rod 8 and is in contact with the upper end of the positioning block 13, and then a plurality of sieve plates 7 are docked with the limiting rod 8 in the order of increasing aperture sizes from bottom to top, and a plurality of second springs 23 are located between two adjacent positioning blocks 13. At this time, the two adjacent sieve plates 7 are smoothly passed through the rectangular opening 6 under the limiting support of the second springs 23 and the limiting rod 8, and at the same time, the lower end of the rectangular baffle 16 is always in contact with the upper end of the sieve plate 7 under the elastic action of the plurality of first springs 20 in the rectangular cover body 15, and the rectangular opening 6 is pressed by the rectangular baffle 16 The sieve plates 7 are conveniently replaced and cleaned by simply rotating the limit rod 8 to separate from the threaded holder 22 and pulling the limit rod 8 out from the positioning blocks 13. The sugar to be screened is introduced into the cavity 2 through the feed trough 5, and the two vibration motors 10 on the support seat 9 are started. The sieve plates 7 are driven to vibrate back and forth under the elastic force of the first spring 20 and the second spring 23 in cooperation with the machine body 1, so that the sieve plates 7 with decreasing aperture sizes from top to bottom are graded and screened for the sugar, thereby improving the screening effect. The screened sugar is concentrated in the residual material recovery groove 11 along the inclined bottom of the cavity 2, and the sugar retained on the sieve plate 7 only needs to pull the handle 17 to open the rectangular baffle 16 on one side, so that the sugar on the sieve plate 7 is vibrated and discharged and collected along the rectangular opening 6 and the discharge chute 12.
