The power shaft 5 is used to drive the multiple screen plates 4 to slide back and forth continuously in the transverse direction, so that the silicon blocks falling from the feed port 2 continuously move transversely relative to the screen plate 4, so that the silicon blocks of qualified size quickly pass through the screen holes and fall downward, while the silicon blocks of larger size remain on the screen plate 4. The remaining large-particle silicon blocks also continuously move transversely relative to the screen plate 4, thereby avoiding their continuous clogging of the screen holes and ensuring the screening efficiency under continuous use. The side welding of the screen plate 4 located inside the screening box 1 Or it is integrally formed with a fence 6 fixed thereto. The setting of the fence 6 can limit and block the incoming silicon blocks on the sieve plate 4, so that the sieve plate 4 can avoid splashing of the silicon blocks when it moves laterally laterally, so that it can be kept on the sieve plate 4 for rapid screening operation. A tension spring 7 is provided between one end of the fence 6 and the side wall of the screening box 1. When the power shaft 5 drives the sieve plate 4 to slide laterally, the tension spring 7 is stretched. After the power shaft 5 is separated from the sieve plate 4, the sieve plate 4 slides and resets under the action of the tension spring 7, thereby realizing continuous reciprocating sliding drive of the sieve plate 4. A plurality of penetrating material distribution ports 8 are provided on the side of the screening box 1. One side of the sieve plate 4 The end passes through the dividing port 8 and is slidably connected thereto, and an inclined discharge plate 9 is welded or bolted at the dividing port 8. Such a structure enables the enclosure 6 to be only arranged on the side of the sieve plate 4 located inside the screening box 1, while the end thereof passing through the dividing port 8 is not provided with the enclosure 6, thereby forming a notch, and the large-grain silicon blocks remaining on the sieve plate 4 gradually fall from the notch during the continuous lateral movement, and then fall from the discharge plate 9 of the dividing port 8, thereby realizing timely separation and collection of the large-grain silicon blocks screened out from multiple sieve plates 4, thereby avoiding blockage of the sieve plate 4 by the large-grain silicon blocks, and ensuring the screening efficiency of the sieve plate 4 after long-term use.
[0023] Preferably, refer to Figure 3A partition 10 is welded or bolted inside the screening box 1, and the power shaft 5 and the screen plate 4 are respectively located on both sides of the partition 10. Such a structure uses the partition 10 to separate the power area of the power shaft 5 and the screening area of the screen plate 4, so as to prevent silicon blocks from entering the power area of the power shaft 5 and interfering with the rotation of the power shaft 5, thereby ensuring the smoothness of the screening sliding motion drive. A plurality of through holes 11 are provided on the partition 10, and one end of the screen plate 4 contacts the power shaft 5 after passing through the through hole 11. Such a structure enables the screen plate 4 to continuously pass through the through hole 11 and contact the power shaft 5, thereby ensuring the stability of the driving structure.
[0024] Preferably, refer to Figure 5 , a plurality of support rods 12 are welded or bolted on one side of the power shaft 5, and the support rods 12 extend toward one side of the power shaft 5, so that when the power shaft 5 rotates, the support rods 12 will intermittently contact or separate from the screen plate 4, and the support rods 12 are rotatably connected to the driving wheel 13 through the bearing, and the driving wheel 13 is in rolling contact with one end of the enclosure 6. When the driving wheel 13 on the support rod 12 contacts the enclosure 6, such a structure drives the enclosure 6 and the screen plate 4 to slide. As the driving wheel 13 on the support rod 12 continues to rotate and separates from the enclosure 6 and the screen plate 4, the screen plate 4 and the enclosure 6 are reset to slide under the action of the tension spring 7, thereby realizing the reciprocating sliding drive of the screen plate 4. During the driving process, the driving wheel 13 on the support rod 12 is in rolling contact with the enclosure 6, which makes the contact and separation between the two smoother, and is not prone to jamming and wear, further ensuring the smoothness of the driving structure.

A rake plate 15 used in conjunction with the sieve plate 4 is welded or bolted at the movable end of the telescopic rod 14. A plurality of rake bars are provided at the bottom of the rake plate 15, and there are gaps between the plurality of rake bars. Such a structure utilizes the telescopic rod 14 to drive the rake plate 15 to push the large-grain silicon blocks remaining on the sieve plate 4 toward the direction of the material distribution port 8, thereby allowing the large-grain silicon blocks to be separated from the sieve plate 4 more quickly. The gaps between the rake bars can avoid pushing smaller silicon blocks that meet the size, further ensuring the screening effect.
[0026] Preferably, a plurality of guide grooves 16 are symmetrically provided on the side walls of the screening box 1, and the guide grooves 16 are recessed inward from the inner walls of the screening box 1. The bottom of the screening plate 4 is symmetrically rotatably connected with a plurality of guide wheels 17 through bearings, and the guide wheels 17 are rollingly connected in the guide grooves 16. Such a structure enables the guide wheels 17 to roll in the guide grooves 16 when the screening plate 4 slides laterally, thereby reducing the resistance to the lateral movement of the screening plate 4, thereby making the entire screening process smoother and more efficient.
[0027] Preferably, a plurality of sealing plates 18 are symmetrically welded or bolted on the side wall of the screening box 1, the enclosure 6 is in sliding contact with the bottom of the sealing plate 18, and the top of the sealing plate 18 is inclined. Such a structure utilizes the sealing plate 18 to fill and seal the gap between the enclosure 6 and the side wall of the screening box 1, thereby preventing silicon blocks from falling into the gap between the two and causing jamming, and allowing the fallen silicon blocks to fall more concentratedly toward the screen plate 4, further ensuring the smoothness and stability of the operation of the screening structure.
[0028] Working principle: The structure of the utility model is to set a plurality of transversely sliding screen plates 4 in the screening box 1, and use the power shaft 5 to drive the screen plate 4 to slide transversely, so that the silicon blocks falling from the feed port 2 fall on the screen plate 4 and are blocked by the enclosure 6 and restricted on the screen plate 4, and the silicon blocks blocked by the enclosure 6 can continuously slide transversely relative to the screen plate 4, so that the silicon blocks that meet the size can quickly fall from the sieve holes on the screen plate 4 and then be discharged from the lower discharge port 3, and the large-particle silicon blocks screened out continuously move transversely relative to the screen plate 4, thereby avoiding their continuous blocking of the sieve holes on the screen plate 4, thereby ensuring the screening effect under continuous use. A plurality of distribution ports 8 are arranged on the side of the screening box 1, one end of the sieve plate 4 passes through the distribution port 8 and is slidably connected thereto, and an inclined discharge plate 9 is arranged at the distribution port 8. Such a structure enables the enclosure 6 to be arranged only on the side inside the screening box 1, while the side of the sieve plate 4 located outside the distribution port 8 is not provided with the enclosure 6. Such a structure enables the large-particle silicon blocks screened out to fall from the end without the enclosure 6 during the continuous lateral movement, and then be discharged from the distribution port 8 along the discharge plate 9, thereby realizing the timely separation of the large-particle silicon blocks, and thereby enabling the sieve plate 4 to maintain a sufficient screening effect for a long time, thereby ensuring the screening efficiency under the continuous operation of the equipment.
