[0024] Reference Figure 1 , Figure 3 and Figure 4, the utility model provides an embodiment: a multi-layer screening device for processing porous bricks, comprising a screen box 1, a support base 2 is fixedly connected to the lower surface of the screen box 1, a support frame 30 is fixedly connected to one side of the support base 2, a hydraulic cylinder 22 is fixedly connected to the upper surface of the support frame 30, a slide bar 15 is fixedly connected to the output end of the hydraulic cylinder 22, a connecting rod 20 is slidably connected to the outer wall of the slide bar 15, a bearing 21 is arranged inside the connecting rod 20, a material storage box 17 is fixedly connected to the outer wall of the bearing 21, a fixing bar 19 is fixedly connected to the outer wall of the connecting rod 20, a column 18 is fixedly connected to one side of the fixing bar 19, welding seats 8 are arranged on both sides of the screen box 1, a positioning pin 6 is fixedly connected to one end of the welding seat 8, a limiting block 7 is fixedly connected to the outer wall of the positioning pin 6, a rubber pad 23 is fixedly connected to the lower surface of the limiting block 7, a shock-absorbing spring 9 is fixedly connected to the lower surface of the rubber pad 23, a telescopic rod 31 is arranged in the middle of the shock-absorbing spring 9, and the lower surface of the shock-absorbing spring 9 is fixedly connected to the support base 2.

[0025] Specifically, when raw materials need to be screened, the output end of the hydraulic cylinder 22 on the support frame 30 pushes the slide bar 15 upward to slide back and forth, thereby driving one end of the connecting rod 20 to move upward and the other end to move downward under the rotation of the bearing 21, so that the material box 17 filled with raw materials moves upward and tilts toward the feed port 26 and pours the raw materials onto the screen 25 through the feed port 26, thereby realizing the transportation and delivery of the raw materials.

[0026] Reference Figure 2 , Figure 3 and Figure 4 A first discharge port 27 is provided at one end of the screen box 1, a second discharge port 28 is provided at the lower side of the first discharge port 27, a third discharge port 29 is provided at the lower side of the second discharge port 28, a screen frame 24 is fixedly connected to the inside of the screen box 1, a screen 25 is fixedly connected to the upper surface of the screen frame 24, a screen fixing screw 16 is fixedly connected to the outer side of the screen 25, one end of the screen fixing screw 16 is fixedly connected to the outer wall of the screen box 1, a splash guard 4 is fixedly connected to the upper surface of the screen box 1, a guide plate 5 is fixedly connected to the outer wall of the screen box 1, a splash guard 4 is fixedly connected to the upper surface of the screen box 1, a vibration assembly 3 is provided at the lower side of the splash guard 4, an inlet 26 is provided on one side of the screen box 1, the vibration assembly 3 includes a first motor 10, a grease nipple 12 is provided on the upper surface of the first motor 10, a connecting seat 11 is fixedly connected to the lower surface of the first motor 10, a pin hole 14 is provided inside the connecting seat 11, and a fixing pin 13 is fixedly connected inside the pin hole 14.

[0027] Specifically, the output end of the first motor 10 in the vibration assembly 3 is started at the same time, so that the screen frame 24 in the screen box 1 vibrates at a high frequency, driving the three-layer screen 25 to screen the raw materials. Through the screening of the three-layer screen 25, the screened raw materials are discharged through the guide plate 5 at the first discharge port 27, the second discharge port 28 and the third discharge port 29, respectively, to achieve multi-level fine screening of the raw materials. During the screening, the shock-absorbing spring 9 and the rubber pad 23 on the support base 2 reduce the vibration noise of the vibration assembly 3 and the screen frame 24 in the screen box 1 through the positioning pin 6 fixed on the limit block 7 and the conduction through the welding seat 8.

[0028] Working principle: when it is necessary to screen the raw materials, the output end of the hydraulic cylinder 22 on the support frame 30 is pushed upward to allow the slide bar 15 to slide back and forth, thereby driving one end of the connecting rod 20 to move upward and the other end to move downward under the rotation of the bearing 21, so that the material box 17 filled with raw materials moves upward while tilting toward the feed port 26 and pouring the raw materials onto the screen 25 through the feed port 26, thereby realizing the transportation and delivery of the raw materials. At the same time, the output end of the first motor 10 in the vibration assembly 3 is started to allow the screen frame 24 in the screen box 1 to vibrate at a high frequency, thereby driving the three-layer screen 25 to screen the raw materials. Through the screening of the three-layer screen 25, the screened raw materials are discharged through the guide plate 5 at the first discharge port 27, the second discharge port 28 and the third discharge port 29, respectively, thereby realizing multi-level fine screening of the raw materials.

[0029] Secondly, when screening is performed, the shock-absorbing spring 9 and the rubber pad 23 on the supporting base 2 reduce the vibration noise of the vibration assembly 3 and the screen frame 24 in the screen box 1 through the conduction of the positioning pin 6 fixed on the limit block 7 through the welding seat 8.

[0030] 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.
