Description

Technical Field

[0001] This utility model relates to the field of vibrating screen structure technology, specifically to a mechanism for adjusting the tilt angle of a multi-layer vibrating screen plate. Background Technology

[0002] Vibrating screens are frequently used for sorting iron ore, rare earth ore, tin ore, lithium feldspar, and other materials. There are many types of vibrating screens, among which the multi-layer vibrating screen is the most commonly used in wet separation of fine-particle materials. The multi-layer vibrating screen is a multi-layer parallel self-synchronizing inertial linear vibrating screen. Its structural features are that three to five screen boxes are connected in parallel to form a screen box group, which is suspended from the outer support by springs. The outer support has hinge seats at the front and rear, and the two hinge seats are installed on the ground. Two vibrating motors drive the screen box group to vibrate in a self-synchronizing manner. All screen surfaces are parallel and tilted downwards at a fixed angle. Each screen box has an independent feeding device. The screen box is equipped with a screen mesh. The oversize material of each screen box is collected and discharged in a centralized manner, and the undersize material of each screen box is collected and discharged in a centralized manner. In order to improve its process performance, an angle adjustment mechanism for the screen plate is often used to improve its fit to the actual screening conditions.

[0003] Chinese Invention Patent Publication No. CN108393263B discloses an adjustable-angle stacked vibrating fine screen. When reducing the angle between the screen box and the ground, the fixing pin is first pulled out, then the lead screw is rotated in the opposite direction. The external thread A rotates in the upper nut. At this time, the sliding sleeve of the upper crossbeam moves upward along the sliding column. During the movement, the outer frame rotates to the right around the front hinge seat. The overall structure is compact, the screen box angle is adjustable, the operation is simple, and it meets the grading effect required by customers. However, this adjustable-angle stacked vibrating fine screen can only achieve the angle adjustment of the entire screen frame, and it is not convenient to achieve the angle of a single screen plate, resulting in significant limitations in use, making it difficult to adapt to different working conditions and resulting in poor practicality. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a tilt angle adjustment mechanism for the screen plate of a stacked vibrating screen, which can effectively solve the problems in the prior art.

[0005] The technical solution adopted by this utility model is: a tilt angle adjustment mechanism for a stacked vibrating screen plate, comprising a stacked vibrating screen frame and a screen plate body. A connecting plate one and a connecting plate two are respectively fixedly installed at the two ends of the stacked vibrating screen frame away from the outer edge of the screen plate body and located at the vertical center line. A connecting sleeve two is fixedly installed at the other end of the connecting plate two away from the stacked vibrating screen frame. A rotating rod two is rotatably installed at the other end of the connecting sleeve two away from the stacked vibrating screen frame. A mounting seat two is rotatably installed at the two ends of the rotating rod two away from the connecting sleeve two. A vertical adjustment component is rotatably installed at the other end of the mounting seat two away from the stacked vibrating screen frame. A longitudinal adjustment component located on the vibrating screen frame is fixedly installed at the other end of the vertical adjustment component away from the stacked vibrating screen frame.

[0006] The vertical adjustment assembly includes a parallel cylinder, a connecting block that is rotatably connected to the mounting base is fixedly installed on the output shaft of the parallel cylinder, and a fixing block that is rotatably connected to the longitudinal adjustment assembly is fixedly installed at the other end of the parallel cylinder away from the connecting block.

[0007] The longitudinal adjustment assembly includes a connecting rod, an electric slider that is rotatably connected to the fixed block, and an electric slide block. The outer surface of the electric slider is provided with a positioning hole and a connecting groove.

[0008] Preferably, the connecting shaft is rotatably mounted on the end of the connecting block near the mounting base two, and the extension of the connecting shaft away from the connecting block is fixedly mounted to the mounting base two.

[0009] Through the above technical solution, by designing the connecting block, the connecting shaft can pass through the shaft hole of the mounting base 2. Then, the connecting shaft can serve as a fulcrum for rotation, allowing the connecting block to swing freely around the mounting base 2, adapting to the angle changes during the extension and retraction of the parallel cylinders.

[0010] Preferably, a second connecting shaft is rotatably mounted on the other end of the fixed block away from the connecting block, and the extended portion of the second connecting shaft away from the fixed block is fixedly mounted to the longitudinal adjustment component.

[0011] Through the above technical solution, by cooperating with the longitudinal adjustment component, one end of the connecting shaft two is fixed on the electric slider or connecting rod of the longitudinal adjustment component, and the fixing block is connected to the connecting shaft two through the bearing, so as to realize the rotation around the longitudinal adjustment component.

[0012] Preferably, a limiting block is fixedly installed at the other end of the fixing block away from the mounting base. One end of the limiting block has a plurality of limiting holes symmetrically distributed about the center line of the connecting rod, and the limiting holes are adapted to the positioning holes.

[0013] With the above technical solution, when the parallel cylinder is adjusted to the target angle, the limiting hole above the limiting block is aligned with one of the multiple positioning holes. Then, a positioning pin or bolt is inserted into the limiting hole and the aligned positioning hole, passing through the aligned hole to lock the position of the fixed block and the electric slider. Multi-level and multi-angle adjustment can be achieved according to the actual situation, so as to adapt to different working conditions.

[0014] Preferably, the other end of the connecting plate away from the stacked vibrating screen frame is threadedly connected to a positioning bolt extending to the inner surface of the stacked vibrating screen frame, and a connecting sleeve is fixedly installed on the other end of the connecting plate away from the stacked vibrating screen frame.

[0015] With the above technical solution, the connecting plate is attached to the outer edge of the stacked vibrating screen frame, and the positioning bolt is passed through the connecting plate and screwed into the screw hole of the screen frame to fix the position of the connecting plate. When the vertical adjustment component and the longitudinal adjustment component are adjusted, the stacked vibrating screen frame can rotate around the rotating rod.

[0016] Preferably, a rotating rod is rotatably mounted on the inner surface of the connecting sleeve away from the connecting plate, and mounting bases are fixedly mounted on both ends of the rotating rod away from the center line and located at the extension portion of the connecting sleeve.

[0017] Through the above technical solution, and through the design of the rotating rod, the rotating rod rotates freely within the connecting sleeve through the bearing, providing a lateral swing fulcrum for the stacked vibrating screen frame.

[0018] Preferably, the mounting base is fixedly mounted on the vibrating screen frame, and the inner surface of the mounting base is provided with a bushing that is adapted to the rotating rod.

[0019] By using the above technical solution and designing the bushing to connect the bushing to the shaft hole of the mounting base, the rotating rod can rotate smoothly, reducing adjustment resistance and improving operational flexibility.

[0021] 1. This mechanism for adjusting the tilt angle of the screen plate of a stacked vibrating screen, after the parallel cylinder is adjusted to the target angle, makes the limiting hole above the limiting block aligned with one of the multiple positioning holes. Then, a positioning pin or bolt is inserted into the limiting hole and the aligned positioning hole, passing through the aligned hole to lock the position of the fixed block and the electric slider. Multi-level and multi-angle adjustment can be achieved according to the actual situation, so as to adapt to different working conditions.

[0022] 2. This tilt angle adjustment mechanism for the screen plate of a stacked vibrating screen, through the design and cooperation of the longitudinal adjustment component and the vertical adjustment component, can achieve multi-range angle adjustment. During installation, it only needs to be installed on the outer frame of the screen plate. It can be combined with the feature of multiple screen plates of the stacked vibrating screen to achieve different angle adjustments of multiple screen plates. It can also be installed on the outer surface of the overall frame to achieve angle adjustment of the entire frame, thereby improving the versatility of the overall adjustment mechanism.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1: As Figure 1-7 As shown, the present invention provides a tilt angle adjustment mechanism for a stacked vibrating screen plate, comprising a stacked vibrating screen frame 1 and a screen plate body 14. A connecting plate 1 and a connecting plate 2 are fixedly installed at the two ends of the stacked vibrating screen frame 1 away from the outer edge of the screen plate body 14 and located at the vertical center line, respectively. A connecting sleeve 2 9 is fixedly installed at the other end of the connecting plate 2 8 away from the stacked vibrating screen frame 1. A rotating rod 2 10 is rotatably installed at the other end of the connecting sleeve 2 9 away from the stacked vibrating screen frame 1. Mounting base 2 11 is rotatably installed at both ends of the rotating rod 2 10 away from the connecting sleeve 2 9. A vertical adjustment component 12 is rotatably installed at the other end of the mounting base 2 11 away from the stacked vibrating screen frame 1. A longitudinal adjustment component 13 located on the vibrating screen frame is fixedly installed at the other end of the vertical adjustment component 12 away from the stacked vibrating screen frame 1.

[0033] The vertical adjustment assembly 12 includes a parallel cylinder 1201. A connecting block 1202, which is rotatably connected to the mounting base 11, is fixedly installed on the output shaft of the parallel cylinder 1201. A fixing block 1204, which is rotatably connected to the longitudinal adjustment assembly 13, is fixedly installed at the other end of the parallel cylinder 1201 away from the connecting block 1202.

[0034] The longitudinal adjustment assembly 13 includes a connecting rod 1301, an electric slider 1302 rotatably connected to the fixed block 1204, and an electric slide block 1305. The outer surface of the electric slider 1302 is provided with a positioning hole 1304 and a connecting groove 1303.

[0035] Specifically, the connecting block 1202 is rotatably mounted with the connecting shaft 1203 at one end near the mounting base 2 11. The extension of the connecting shaft 1203 away from the connecting block 1202 is fixedly mounted with the mounting base 2 11. The advantage is that, through the design of the connecting block 1202, the connecting shaft 1203 can pass through the shaft hole of the mounting base 2 11. Then, the connecting shaft 1203 serves as a fulcrum for rotation, allowing the connecting block 1202 to swing freely around the mounting base 2 11, adapting to the angle changes when the parallel cylinder 1201 extends and retracts.

[0036] Specifically, a connecting shaft 1205 is rotatably mounted on the other end of the fixed block 1204 away from the connecting block 1202. The extension of the connecting shaft 1205 away from the fixed block 1204 is fixedly mounted to the longitudinal adjustment component 13. The advantage is that, through the cooperation between the connecting shaft 1205 and the longitudinal adjustment component 13, one end of the connecting shaft 1205 is fixed to the electric slider 1302 or connecting rod 1301 of the longitudinal adjustment component 13. The fixed block 1204 is connected to the connecting shaft 1205 through a bearing, so as to realize the rotation around the longitudinal adjustment component 13.

[0037] Specifically, a limiting block 1206 is fixedly installed at the other end of the fixing block 1204 away from the mounting base 11. One end of the limiting block 1206 has multiple limiting holes 1207 symmetrically distributed about the center line of the connecting rod 1301. The limiting holes 1207 are adapted to the positioning holes 1304. The advantage is that when the parallel cylinder 1201 is adjusted to the target angle, the limiting holes 1207 above the limiting block 1206 are aligned with one of the positioning holes 1304. Then, a positioning pin or bolt is inserted into the limiting hole 1207 and the aligned positioning hole 1304, and the position of the fixing block 1204 and the electric slider 1302 is locked. Multi-level and multi-angle adjustment can be achieved according to the actual situation, so as to facilitate adaptation to different working conditions.

[0038] Example 2: Figure 2-7 As shown, this is an improvement on the previous embodiment.

[0039] Specifically, the other end of the connecting plate 2 away from the stacked vibrating screen frame 1 is threaded with a positioning bolt 3 extending to the inner surface of the stacked vibrating screen frame 1. The other end of the connecting plate 2 away from the stacked vibrating screen frame 1 is fixedly installed with a connecting sleeve 4. The advantage is that by attaching the connecting plate 2 to the outer edge of the stacked vibrating screen frame 1, and by passing the positioning bolt 3 through the connecting plate 2 and screwing it into the screw hole of the screen frame, the position of the connecting plate 2 is fixed. When the vertical adjustment component 12 and the longitudinal adjustment component 13 are adjusted, the stacked vibrating screen frame 1 can rotate around the rotating rod 5.

[0040] Specifically, a rotating rod 5 is rotatably mounted on the inner surface of the connecting sleeve 4 away from the connecting plate 2. Mounting bases 6 are fixedly mounted on both ends of the rotating rod 5 away from the center line and located on the extension of the connecting sleeve 4. The advantage is that, through the design of the rotating rod 5, the rotating rod 5 can rotate freely in the connecting sleeve 4 through the bearing, providing a lateral swing fulcrum for the stacked vibrating screen frame 1.

[0041] Specifically, the mounting base 6 is fixedly installed on the vibrating screen frame, and the inner surface of the mounting base 6 is provided with a bushing 7 that is compatible with the rotating rod 5. The advantage is that by connecting the bushing 7 to the shaft hole of the mounting base 6, the rotating rod 5 can rotate smoothly, reducing adjustment resistance and improving operational flexibility.

[0042] Working principle: During use, the connecting plate 12 is fixed to the outer edge of the stacked vibrating screen frame 1 by the positioning bolt 3. The connecting sleeve 14 is fixed synchronously with the connecting plate 12. The rotating rod 15 is installed in the connecting sleeve 14 through the bearing. The mounting seats 16 at both ends are fixed to the vibrating screen frame through the bushing 7 to form a lateral swing fulcrum. The connecting plate 28 is fixed to the outer edge of the other side of the screen frame. The connecting sleeve 29 is installed with the rotating rod 20 through the bearing. The mounting seats 21 at both ends are rotatably connected to the vertical adjustment component 12. The electric slide 1305 of the longitudinal adjustment component 13 is fixed to the frame. The connecting rod 1301 passes through the electric slide 1305 and is slidably connected to the electric slider 1302. During adjustment, the parallel cylinder 1201 rotates around the mounting base 11 via the connecting block 1202 and the connecting shaft 1203, driving the screen frame to rotate around the rotating rod 5 to achieve vertical tilt adjustment. The electric slider 1302 slides longitudinally along the connecting rod 1301 to compensate for lateral displacement. After adjusting to the target angle, the limiting block 1206 is pushed to align the limiting hole 1207 with the positioning hole 1304, and the positioning pin or bolt is inserted to lock it. Through the support of the rotating rod 5 and the rotating rod 10 and the bushing 7, the adjustment mechanism can be installed on different screen plates, thereby realizing the adjustment of different angles of multiple screen plates and improving the versatility of use.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
