Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 , an embodiment provided by the utility model:

[0030] A raw material screening device with good screening effect includes a shell 1, which is characterized in that: fixed plates 2 are fixedly provided at the four corners of the lower end of the inner side of the shell 1, and a No. 1 spring 3 is provided on the upper ends of the four fixed plates 2; a vibration motor 5 is fixedly provided at the middle position on one side of the inner end of the shell 1, a screen frame 4 is fixedly provided at the output end of the vibration motor 5, a screen plate 6 is fixedly provided at the inner end of the screen frame 4, a discharge port 7 is provided at the outer end of the shell 1 near the screen plate 6, a primary screening mechanism 8 is fixedly provided at the upper end of the inner side of the shell 1, a collecting box 9 is movably provided at the inner bottom end of the shell 1, a limiting mechanism 10 is movably provided at the lower end of both sides of the shell 1, and a card slot 11 is provided at the lower end of both sides of the shell 1 near the limiting mechanism 10.

[0031] Specifically, the material is added from the feeding port, the primary screening mechanism 8 will remove the larger impurities inside the material, and then the vibration motor 5 will be turned on, the vibration motor 5 will drive the screen plate 6 to vibrate, thereby screening the material for the second time, and finally the material falls into the collection box 9. After pulling out the collection box 9, the material after screening can be taken out.

[0032] Reference Figure 6 、 Figure 7 The primary screening mechanism 8 includes a No. 1 motor 801 and a screening ring 806. The output end of the No. 1 motor 801 is rotatably provided with a No. 1 rotating column 802. The end of the No. 1 rotating column 802 away from the No. 1 motor 801 is fixedly sleeved with a No. 1 bevel gear 803. The bottom end of the screening ring 806 is rotatably provided with a No. 2 rotating column 804. The upper end of the No. 2 rotating column 804 is fixedly sleeved with a No. 2 bevel gear 805. The outer end of the No. 2 rotating column 804 is fixedly sleeved with a scraper rod 807.

[0033] The scraper rod 807 is rotatably arranged at the bottom end of the screening ring 806, the screening ring 806 is fixedly arranged at the upper end of the screen plate 6, and the screen frame 4 is fixedly connected to the No. 1 spring 3;

[0034] The first bevel gear 803 is meshed with the second bevel gear 805 , and the first motor 801 is fixedly arranged on the outer side of the housing 1 near the upper end.

[0035] Specifically, when the material passes through the primary screening mechanism 8, the No. 1 motor 801 will drive the No. 1 rotating column 802 to rotate. Since the No. 1 bevel gear 803 is engaged with the No. 2 bevel gear 805, it will drive the No. 2 rotating column 804 to rotate. When the No. 2 rotating column 804 rotates, the screening ring 806 is in a stationary state, and the scraper 807 will push the material on the upper end of the screening ring 806 to rotate. The passed material will enter the screen plate 6 for secondary screening. The scraper 807 can ensure that the material can fully pass through the sieve hole, reducing the loss caused by material retention and improving the recovery rate of raw materials.

[0036] Reference Figure 8 、 Figure 9The limiting mechanism 10 includes two clamping plates 1001, and a No. 2 spring 1002 is provided at the upper end and the lower end of the rear side of the two clamping plates 1001. A No. 3 spring 1003 is provided at the middle position of the rear side of the two clamping plates 1001. The rear ends of the two No. 3 springs 1003 are fixedly provided with movable blocks 1004, and the outer ends of the two movable blocks 1004 are fixedly provided with clamping blocks 1005;

[0037] Two clamping plates 1001 are movably arranged at both ends of the collecting box 9, and the rear ends of four No. 2 springs 1002 are fixedly arranged on the inner side of the housing 1 near the bottom end.

[0038] The two movable blocks 1004 are movably arranged in the holes on both sides of the housing 1 near the lower end, and the two clamping blocks 1005 are movably arranged at the inner end of the clamping slot 11.

[0039] Specifically, after the second screening of the material is completed, the material will fall into the collecting box 9. A measuring device is placed at the bottom of the outer shell 1, and the machine will stop when the collecting box 9 is pulled out. Since one end of the card plate 1001 is a curved edge and the other side is a straight edge, when the straight edge contacts the collecting box 9, the collecting box 9 can be supported to prevent the staff from misoperating when the material is not completely collected, reducing the equipment shutdown caused by improper operation. After the collecting box 9 is filled, it is necessary to pull the movable block 1004 outward, and the card block 1005 will fall out of the card slot 11, and then the collecting box 9 can be taken out.

[0040] Working principle: When the material passes through the primary screening mechanism 8, the No. 1 motor 801 drives the No. 1 rotating column 802 to rotate. Since the No. 1 bevel gear 803 is engaged with the No. 2 bevel gear 805, it drives the No. 2 rotating column 804 to rotate. When the No. 2 rotating column 804 rotates, the screening ring 806 is in a stationary state, and the scraper 807 pushes the material on the upper end of the screening ring 806 to rotate. The passed material will enter the screen plate 6 for secondary screening;

[0041] Secondly, after the second screening of the material is completed, the material will fall into the collection box 9. Since one end of the card plate 1001 is a curved edge and the other end is a straight edge, when the straight edge contacts the collection box 9, the collection box 9 can be supported to prevent the staff from mistakenly taking out the collection box 9 that has not been completely collected. After the collection box 9 is filled, it is necessary to pull the movable block 1004 outward, and the card block 1005 will fall out of the card slot 11, and then the collection box 9 can be taken out.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
