Description

Technical Field

[0001] The utility model relates to a vibrating screen plate with adjustable distance, belonging to the field of vibrating screens. Background Art

[0002] In the mining, construction, chemical and other industries, vibrating screen plates, as key screening equipment, are widely used in screening operations of various solid materials.

[0003] Vibrating screen plates usually adopt a design of vibrating screen bars or screen holes with fixed spacing. Although this design can meet certain screening needs, when processing materials containing a large number of irregular particles such as gravel and slag, this design makes the screen holes easily stuck by irregularly shaped gravel, slag and other materials, resulting in reduced screening efficiency. In severe cases, it may even require shutdown for cleaning, which seriously affects production continuity. Once the screen holes are blocked, they usually need to be cleaned manually or with special tools. This cleaning method is not only time-consuming and labor-intensive, but also inefficient, increasing production costs. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] For example, see Figure 1-4 A vibrating screen plate with adjustable spacing includes a screen frame 1, a first frame body 2 fixedly connected to the inner top wall of the screen frame 1, and a second frame body 3 fixedly connected to the inner bottom wall of the screen frame 1. An adjusting structure for adjusting the spacing is provided on the inner side of the first frame body 2.

[0027] like Figure 1 As shown, the adjustment structure includes a slide rod 4 fixedly connected to the inner side of the first frame 2, a slider 5 slidably connected to the outer side of the slide rod 4, a connecting block 6 fixedly connected to the front side of the slider 5, and a screen bar 7 fixedly connected to the bottom of the connecting block 6;

[0028] A positioning assembly for positioning the screen bars 7 is provided on the inner side of the second frame 3 .

[0029] It should be noted that the left end of the slide bar 4 is fixedly connected to the inner left side wall of the first frame body 2 , and the right end of the slide bar 4 is fixedly connected to the inner right side wall of the first frame body 2 .

[0030] A connecting frame 8 is fixedly connected to the outer side of the connecting block 6 , and the connecting frame 8 is fixedly connected to the front side of the sliding block 5 .

[0031] The number of the sliders 5 is five, and the five sliders 5 are arranged equidistantly in the horizontal direction. The front side of the first frame body 2 is provided with a sliding opening adapted to the sliders 5 .

[0032] The positioning assembly includes four elastic telescopic rods 9 fixedly connected to the inner bottom wall of the second frame 3, a positioning plate 10 fixedly connected between the top ends of the piston rods of the four elastic telescopic rods 9, a rotating rod 11 rotatably connected to the inner side of the second frame 3, a support block 12 fixedly connected to the outer side of the rotating rod 11, and a toggle wheel 13.

[0033] The four elastic telescopic rods 9 are respectively fixedly connected to the four corners of the inner bottom wall of the second frame body 3. The upper surface of the second frame body 3 is provided with a movable opening adapted to the positioning plate 10. The upper surface of the positioning plate 10 is provided with nine positioning grooves, and the bottom of the screen bar 7 is fixedly connected with a positioning block 14 adapted to the positioning groove.

[0034] There are five support blocks 12 , and the five support blocks 12 are arranged equidistantly in the horizontal direction. The left end of the rotating rod 11 is rotatably connected to the inner left side wall of the second frame 3 , and the right end of the rotating rod 11 is rotatably connected to the inner right side wall of the second frame 3 .

[0035] A shield 15 is fixedly connected to the front of the second frame body 3 , and a cover door is arranged on the front of the shield 15 . A shifting opening located inside the shield 15 and matched with the shifting wheel 13 is opened on the front of the second frame body 3 .

[0036] The shield 15 is provided to prevent the material from coming into contact with the toggle wheel 13 during the screening process, thereby ensuring the stability of the positioning assembly.

[0037] The working principle of the above embodiment is:

[0038] When the operating slider 5 moves horizontally along the slide rod 4, the slide rod 4 serves as the main guiding component to ensure that the slider 5 maintains a stable trajectory during the movement. The slider 5 is connected to the connecting frame 8, and the connecting frame 8 further forms a linkage relationship with the connecting block 6. When the slider 5 moves stably, the connecting block 6 moves synchronously through the transmission of the connecting frame 8, and the movement of the connecting block 6 directly drives the screen bars 7 to move, thereby realizing the precise adjustment of the spacing between the screen bars 7.

[0039] In order to ensure the position stability of the screen bar 7 after adjustment, under the elastic extension of the elastic telescopic rod 9, the positioning plate 10 can adaptively rise, allowing the positioning block 14 on the screen bar 7 to be smoothly inserted into the slot of the positioning plate 10, and then, by rotating the toggle wheel 13, the toggle wheel 13 drives the rotating rod 11 to rotate. During the rotation of the rotating rod 11, the bottom of the support block 12 gradually contacts the inner bottom wall of the second frame 3 and forms a stable support. At the same time, the top of the support block 12 fits tightly with the bottom of the positioning plate 10, thereby forming a stable support structure for the positioning plate 10, ensuring the position stability of the screen bar 7 during the screening process.

[0040] Embodiment 2, based on embodiment 1, a pad can be added at the bottom of the positioning plate 10, and the positioning plate 10 can be effectively supported by the pad to ensure the positioning stability of the positioning assembly on the screen bar 7. In addition, a through opening is opened on the front of the second frame 3 to facilitate the removal of the pad.
