[0025] Referring to Figs. 1-2 An embodiment provided by the present utility model: including base 1 and screening frame 8, screening frame 8 set up in the top of base 1, the upper end of base 1 is rotatably connected with adjusting frame 5, one side of the upper end of base 1 is fixedly connected with hydraulic cylinder 17, the upper end of base 1 is slidably connected with sliding rod 16, the output end of hydraulic cylinder 17 is fixedly connected with one side of sliding rod 16, both ends of sliding rod 16 are rotatably connected with lifting rod 15, one end of two lifting rods 15 is rotatably connected with the two sides of the lower end of adjusting frame 5, the upper end of adjusting frame 5 is fixedly connected with buffer mechanism 6 around, the upper end of four buffer mechanisms 6 is fixedly connected with connecting frame 7, one side of four connecting frames 7 is fixedly connected with the four around of screening frame 8, both corners of the upper end of base 1 are fixedly connected with support rod 14.

[0026] In the embodiment, when the inclination angle of the screening frame 8 needs to be adjusted, the hydraulic cylinder 17 can be started to push the sliding rod 16 to move, and the moving sliding rod 16 will push one end of the lifting rod 15 to move and then make the other end of the lifting rod 15 lift upward, thereby lifting the inclination angle of the adjusting frame 5, and the screening frame 8 fixed on the adjusting frame 5 can be inclined accordingly. By this method, the device can adjust the inclination angle of the screening frame 8 and the screen plate 9 according to the actual screening requirements when facing different particle sizes of quartz sand, so that the device can be more suitable for different particle sizes of quartz sand, and the screening effect of the device is improved.

[0027] Embodiment 2, as Figs. 1-5 shown, the two sides inside the screening frame 8 are fixedly connected with fixed frame 18, the inside of two fixed frames 18 is slidably connected with screen plate 9, one side of one side of screening frame 8 is slidably connected with buckle frame 20, one corner of screening frame 8 is fixedly connected with mounting rod 19, one end of mounting rod 19 is slidably connected with pulling rod 21, one end of pulling rod 21 is fixedly connected with one side of buckle frame 20, one side of buckle frame 20 is fixedly connected with spring 22, one end of spring 22 is fixedly connected with one end of mounting rod 19, the upper side of one side of screening frame 8 is fixedly connected with No. 1 discharge chute 10, the middle of one side of screening frame 8 is fixedly connected with No. 2 discharge chute 11, the lower end of screening frame 8 is fixedly connected with No. 3 discharge chute 12, one side of screening frame 8 is fixedly connected with vibration motor 23, the four around of lower end of base 1 is fixedly connected with support leg 4.

When the screen plate 9 needs to be replaced or disassembled and maintained, the pulling rod 21 can be pulled, which will drive the buckle frame 20 to move and compress the spring 22 after being pulled, so that the end of the buckle frame 20 is withdrawn from the fixed frame 18 on both sides. At this time, the outlet of the fixed frame 18 fixed with the screen plate 9 is released from the limit, and then the screen plate 9 is pulled outwards to slide and buckle the screen plate 9. Subsequent reinstallation only needs to insert the screen plate 9 into the fixed frame 18, and then loosen the pulling rod 21. The compressed spring 22 will be stretched to push the end of the buckle frame 20 back to the position, and the outlet of the fixed frame 18 is re-limited. At this time, the screen plate 9 buckled in the fixed frame 18 can complete the reinstallation work. Through this method, the disassembly and subsequent installation of the screen plate 9 are more convenient when the screen plate 9 needs to be replaced and disassembled, which improves the efficiency of the device in the later maintenance and makes it more convenient to use.
