[0003] The existing vibrating screen generally includes a vibration source and a filter screen. At present, different materials require different strokes for screening. Some materials require a longer stroke for full screening. Since the materials require a shorter stroke for screening, the size of the filter screen of the vibrating screen in the prior art cannot be adjusted, resulting in the inability to adjust the stroke of the vibrating screen. Therefore, a vibrating screen with adjustable stroke is proposed. Utility Model Content

[0006] A vibrating screen with adjustable stroke comprises a first vibrating frame, a second vibrating frame and a filter screen arranged inside the first vibrating frame and inside the second vibrating frame, the first vibrating frame is located below the second vibrating frame, two sides of the first vibrating frame are slidably connected to two sides of the second vibrating frame, one side of the first vibrating frame is symmetrically fixed with two fixing rings, and fixing bolts are inserted inside the fixing rings, fixing screw holes are opened on both sides of the bottom of the second vibrating frame, and the fixing bolts are threadedly connected to the fixing screw holes.

[0007] Preferably, fixing seats are fixedly provided on both sides of the first vibration frame, sliding rods are fixedly provided on the tops of the two fixing seats, and sliding grooves matching with the sliding rods are provided on both sides of the second vibration frame.

[0008] Preferably, the slide rod is an L-shaped rod, and one end of the slide rod extends to the interior of the slide groove.

[0009] Preferably, two suspension seats are symmetrically fixedly provided inside the first vibration frame and on the side opposite to the second vibration frame, and a suspension rod extending upward is fixedly provided on the top of the suspension seat.

[0010] Preferably, there are multiple fixing screw holes, and the multiple fixing screw holes are distributed in a straight line along the length direction of the second vibration frame.

[0011] Preferably, the filter mesh inside the first vibration frame and the filter mesh inside the second vibration frame have the same mesh diameter.

[0012] Compared with the prior art, the utility model provides a vibrating screen with adjustable stroke, which has the following beneficial effects:

[0013] 1. The vibrating screen with adjustable stroke is provided with a first vibrating frame and a second vibrating frame, and the first vibrating frame and the second vibrating frame are connected by fixing bolts and fixing screw holes. When it is necessary to adjust the use length of the filter screen inside the first vibrating frame and the second vibrating frame, the staff loosens the fixing bolts with a wrench, so that the offset position between the first vibrating frame and the second vibrating frame can be adjusted, thereby adjusting the use length of the filter screen, so that the stroke of the vibrating screening can be adjusted, which is suitable for the screening of different materials.

[0014] 2. The stroke-adjustable vibrating screen is provided with a slide rod and a slide groove. When the position between the first vibrating frame and the second vibrating frame is adjusted, the end of the slide rod moves inside the slide groove, thereby increasing the smoothness of sliding between the first vibrating frame and the second vibrating frame.

[0015] 3. The stroke-adjustable vibrating screen has a hanger and a hanger rod arranged on the first vibrating frame and the second vibrating frame, and the upper end of the hanger rod can be connected to a vibration source, so that the first vibrating frame and the second vibrating frame can vibrate and screen the material.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can adjust the use length of the filter screen, so that the vibration screening stroke of the vibrating screen can be adjusted, which can be suitable for different types of materials and improve production efficiency.
