Description

Technical Field

[0001] This utility model relates to the field of vibrating screen technology, and in particular to a guide plate structure for a vibrating screen used for rock cuttings processing. Background Technology

[0002] In the process of rock cuttings treatment in the mining, construction and environmental protection fields, the vibrating screen is the core equipment. The design of its guide plate structure directly affects the screening efficiency and operational safety. When using traditional vibrating screen guide plates, rock cuttings tend to accumulate between the guide plates, resulting in the effective filtration area of ​​the screen not being fully utilized, reducing the processing efficiency. Furthermore, it is impossible to flexibly adjust the deflection force of the guide plates according to the amount of rock cuttings or changes in working conditions, which can easily cause equipment overload or incomplete screening.

[0003] Therefore, it is necessary to provide a new guide plate structure for a vibrating screen used for rock cuttings processing to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a guide plate structure for a vibrating screen for rock cuttings processing.

[0005] The vibrating screen guide plate structure for rock cuttings processing provided by this utility model includes an installation plate. A longitudinally arranged intermediate seat is fixedly installed in the middle of the installation plate. Two symmetrically distributed and rotatably connected guide plates are installed on the seat head of the intermediate seat. Two rotatably connected rotating shafts are installed on the seat head of the intermediate seat. The two guide plates are respectively sleeved on the two rotating shafts and rotatably connected to the rotating shafts.

[0006] The intermediate seat is equipped with a central support plate for supporting the external flow guide plate and a spring acting on the flow guide plate.

[0007] The two side walls of the intermediate seat are provided with side grooves, and a guide rod is fixedly installed in the side groove. A sliding block is slidably connected on the guide rod. One end of the middle support plate is rotatably connected to the inner wall of the guide plate body, and the other end of the middle support plate is rotatably connected to the outer wall of the sliding block.

[0008] The intermediate seat is also equipped with a threaded cylinder for adjusting the elastic force of the spring.

[0009] Preferably, a coaxially arranged screw is fixedly installed at the tail end of the guide rod.

[0010] Preferably, the tail of the intermediate seat has a through hole communicating with the side groove, the threaded cylinder is inserted into the side groove through the through hole, and the threaded cylinder is threadedly connected to the screw. A rotating abutment block is installed at the opening of the threaded cylinder, and the spring is sleeved on the guide rod and the screw between the abutment block and the sliding block.

[0011] Preferably, one end of the spring is fixedly connected to the sliding block, and the other end of the spring is fixedly connected to the abutment block.

[0012] Preferably, a knob is fixedly installed at the tail end of the threaded cylinder.

[0013] Compared with related technologies, the guide plate structure for the vibrating screen used in rock cuttings processing provided by this utility model has the following advantages:

[0014] When rock chips abut against the guide plate, the guide plate deflects backward along the rotation axis, causing the sliding block to slide backward along the guide rod, thereby compressing the spring. After the rock chips slide onto the screen, the next batch of rock chips abuts against the guide plate again. Therefore, the guide plate continuously deflects and resets. Thus, through the synergistic action of the symmetrical guide plate and the spring, the guide plate deflects around the rotation axis and compresses the spring when rock chips impact, achieving coverage of the space on both sides of the screen. By rotating the threaded cylinder, the threaded cylinder slides forward or backward along the screw, thereby changing the distance between the abutting block and the sliding block, thus adjusting the preload of the spring to adapt to different rock chip characteristics.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0022] Please see Figures 1 to 4 The present invention provides a guide plate structure for a vibrating screen for rock cuttings processing, the guide plate structure for a vibrating screen for rock cuttings processing includes an mounting plate 1, a guide plate body 3, a central support plate 6, and a threaded cylinder 8.

[0023] In the embodiments of this utility model, please refer to Figures 1 to 4 A longitudinally arranged intermediate seat 2 is fixedly installed in the middle of the mounting plate 1, and two symmetrically distributed and rotatably connected guide plates 3 are installed on the seat head of the intermediate seat 2. Specifically, two rotatably connected rotating shafts 21 are installed on the seat head of the intermediate seat 2, and the two guide plates 3 are respectively sleeved on the two rotating shafts 21 and rotatably connected to the rotating shafts 21.

[0024] The intermediate seat 2 is equipped with a central support plate 6 for supporting the external guide plate body 3 and a spring 7 acting on the guide plate body 3. Specifically, side grooves 2a are provided on both side walls of the intermediate seat 2, and guide rods 4 are fixedly installed in the side grooves 2a. A screw 41 is fixedly installed at the tail of the guide rod 4, and a sliding block 5 is slidably connected to the guide rod 4. One end of the central support plate 6 is rotatably connected to the inner wall of the guide plate body 3, and the other end of the central support plate 6 is rotatably connected to the outer wall of the sliding block 5. The connection is made such that the tail of the intermediate seat 2 has a through hole that communicates with the side groove 2a. The threaded cylinder 8 is inserted into the side groove 2a through the through hole and is threadedly connected to the screw 41. A rotating abutment block 81 is installed at the opening of the threaded cylinder 8. The spring 7 is sleeved on the guide rod 4 and the screw 41 between the abutment block 81 and the sliding block 5. One end of the spring 7 is fixedly connected to the sliding block 5, and the other end of the spring 7 is fixedly connected to the abutment block 81, thereby improving the stability of the spring 7.

[0025] It should be noted that: the mounting plate 1 is fixedly installed at the feed inlet of the vibrating screen and the middle seat 2 is kept in the middle. Before the rock chips slide backward from the feed inlet of the vibrating screen onto the screen, the two guide plates 3 divert the rock chips to both sides. When the rock chips abut against the guide plates 3, the guide plates 3 deflect backward along the rotating shaft 21 and drive the sliding block 5 to slide backward along the guide rod 4, thereby compressing the spring 7. After the rock chips slide onto the screen, the next batch of rock chips abuts against the guide plates 3 again. Therefore, the guide plates 3 deflect and reset continuously. Thus, through the synergistic effect of the symmetrical guide plates 3 and the spring 7, when the rock chips impact, the guide plates 3 deflect around the rotating shaft 21 to compress the spring 7, thereby achieving coverage of the space on both sides of the screen.

[0026] By rotating the threaded cylinder 8, the threaded cylinder 8 slides forward or backward along the screw 41, thereby changing the distance between the abutment block 81 and the sliding block 5, thus adjusting the preload of the spring 7 to adapt to different rock cutting characteristics.

[0027] Among them, the double-end rotating connection structure of the central support plate 6 (inner wall of the guide plate body 3 + sliding block 5) converts the impact force into spring potential energy, reducing the component damage rate.

[0028] Furthermore, a knob 82 is fixedly installed at the tail of the threaded cylinder 8, which facilitates the rotation of the threaded cylinder 8.

[0029] In addition, corrugated protective sleeves are added to the surfaces of guide rod 4 and screw 41. The material is wear-resistant fluororubber, which seals the gap while maintaining the degree of freedom of sliding. This avoids the hidden danger that rock dust may enter the gap between guide rod 4 and sliding block 5, which may increase the sliding resistance. The spring 7 is made of 60Si2MnA high-stress spring steel, which improves the service life of spring 7.

[0030] Furthermore, an arc-shaped structure is provided on the head of the intermediate seat 2 to prevent rock debris from accumulating on the head of the intermediate seat 2. The staff regularly cleans each component to prevent rock debris from getting stuck in the rotating area of ​​this application and causing a potential jamming problem.

[0031] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
