Description

Technical Field

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

[0002] A vibrating screen is a screening device that uses the principle of vibration to separate materials. It is widely used in industries such as mining, building materials, and chemicals. The motor drives the eccentric block to rotate, generating vibration force, which causes the material to reciprocate on the screen surface and separate according to particle size. The screen plate, as the core component of the vibrating screen, is in direct contact with the material and needs to be stably fixed by a fastening structure.

[0003] The vibrating screen plate is fastened with bolts, nuts, and washers. Rubber pads are added to reduce friction. The edge of the screen plate is designed with mounting holes corresponding to the bolt holes. The bolts pass through the holes in the screen plate and the screen frame and are tightened with nuts to fix the plate. The mechanical force counteracts the separation tendency caused by vibration, prevents relative displacement of the screen plate, ensures synchronous movement with the screen frame, prevents the screen plate from loosening or falling off during high-frequency vibration, and ensures screening efficiency and equipment safety.

[0004] The fastening structure of the vibrating screen plate can fix the screen plate to the screen frame. When the screen plate needs to be cleaned, it is necessary to use a wrench to remove the bolts one by one, which is time-consuming and laborious, prolongs the downtime for replacing the screen plate, and affects production efficiency. Therefore, a fastening structure for the vibrating screen plate is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fastening structure for the screen plate of a vibrating screen, aiming to improve the problem of inconvenient disassembly of the screen plate in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A fastening structure for a vibrating screen plate includes a housing, inside which the screen plate is installed. Two mounting plates are installed on both sides of the outer side of the housing. A mounting shell is fixedly connected to the outside of the mounting plates. A cylinder is fixedly connected to the inside of the mounting shell. A connecting block is fixedly connected to one end of the cylinder. A rotating plate is rotatably connected to the inside of the connecting block. A rotating rod is rotatably connected to one end of the rotating plate. A pressing block is fixedly connected to one end of the rotating rod. The bottom of the pressing block contacts the top of the screen plate. A fixing block is rotatably connected to the other end of the rotating rod. The bottom of the fixing block is fixedly connected to the top of the mounting shell. Mounting components are fixedly connected to both sides of the outer side of the mounting plates.

[0008] As a further description of the above technical solution:

[0009] The mounting assembly includes a fixed housing, a sliding rod slidably connected inside the fixed housing, a locking block fixedly connected inside the sliding rod, a spring sleeved on the outside of the sliding rod, a knob fixedly connected to the other end of the sliding rod, one end of the spring fixedly connected inside the fixed housing, and the other end of the spring fixedly connected outside the knob.

[0010] As a further description of the above technical solution:

[0011] The bottom of the knob contacts the inside of the fixing housing, and the outside of the fixing housing is fixedly connected to the inside of the mounting plate;

[0012] As a further description of the above technical solution:

[0013] The inside of the housing is provided with a slot, and the outside of the sliding rod and the locking block are in contact with the inside of the slot;

[0014] As a further description of the above technical solution:

[0015] The box body is fixedly connected to a discharge port one, and the box body is fixedly connected to a discharge port two.

[0016] As a further description of the above technical solution:

[0017] Both sides of the inside of the box are fixedly connected to a fixing plate, and the bottom of the sieve plate is in contact with the groove of the fixing plate;

[0018] As a further description of the above technical solution:

[0019] Spring 2 is fixedly connected to the bottom of the box on all four sides, and a support frame is fixedly connected to the bottom of spring 2;

[0020] As a further description of the above technical solution:

[0021] A motor base plate is fixedly connected to the bottom of the housing, and two vibration motors are fixedly connected to the outside of the motor base plate.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the cylinder retracts to drive the connecting block, which in turn drives the rotating plate. The other end of the rotating plate is rotatably connected to the fixed block. Therefore, the rotating plate rotates around the fixed block as an axis, thereby driving the pressing block downward to contact the screen plate. Thus, the cylinder drives the screen plate to be fixed on the fixed plate inside the box. When the screen plate needs to be cleaned, the cylinder pushes the connecting block upward, thereby driving the rotating plate. This causes the rotating plate to lift the rotating rod upward and separate from the screen plate, thus removing the screen plate. Therefore, the screen plate can be fastened and quickly disassembled for cleaning.

[0024] 2. In this utility model, by aligning the mounting plate with the groove on the box body, the sliding rod is inserted into the slot. Pressing and rotating the knob compresses the spring, which in turn drives the sliding rod and the locking block to insert into the slot, so that the locking block engages with the slot. Releasing the knob pushes the sliding rod with the spring. Therefore, by rotating the knob, the mounting plate can be fixedly installed on the outside of the box body, which is convenient and quick.

Two mounting plates 3 are installed on both sides of the housing 1. Mounting shells 4 are fixedly connected to the exterior of the mounting plates 3, serving to connect and support the mounting shells 4. A cylinder 5 is fixedly connected inside the mounting shells 4, providing installation space and protection for the cylinder 5. A connecting block 6 is fixedly connected to one end of the cylinder 5, driving the connecting block 6 to extend and retract. A rotating plate 7 is rotatably connected inside the connecting block 6, transmitting power from the cylinder 5 to the connecting block 6. The rotating plate 7 is handed over, and a rotating rod 8 is rotatably connected to one end of the rotating plate 7. A pressing block 9 is fixedly connected to one end of the rotating rod 8. The bottom of the pressing block 9 contacts the top of the screen plate 2. The pressing block 9 presses and fixes the screen plate 2 under the drive of the rotating rod 8 to prevent the screen plate 2 from loosening during vibration. A fixing block 10 is rotatably connected to the other end of the rotating rod 8. The fixing block 10 provides a rotation fulcrum for the rotating rod 8. The rotating rod 8 rotates around the fixing block 10 as an axis under the drive of the rotating plate 7. The bottom of the fixing block 10 is fixedly connected to the top of the mounting shell 4. Mounting components are fixedly connected to both sides of the outer side of the mounting plate 3. The mounting components are used to securely install the mounting plate 3 on the box 1.

[0034] Reference Figures 2 to 4 The mounting assembly includes a fixed housing 12, which is externally fixedly connected to the interior of the mounting plate 3. A sliding rod 13 is slidably connected inside the fixed housing 12, and the sliding rod 13 slides within the fixed housing 12. A locking block 14 is fixedly connected inside the sliding rod 13. A locking groove 11 is provided inside the housing 1. The exterior of the sliding rod 13 and the locking block 14 contacts the interior of the locking groove 11, which provides locking space for the locking block 14. The locking block 14 and the locking groove 11 cooperate to fix the mounting plate 3 to the housing 1. A spring 15 is sleeved on the exterior of the sliding rod 13. One end of the spring 15 is fixedly connected to the interior of the fixed housing 12, and the other end of the spring 15 is fixedly connected to the exterior of a knob 16. The other end of the sliding rod 13 is fixedly connected to a knob 16, and the bottom of the knob 16 contacts the interior of the fixed housing 12. The knob 16 allows the operator to press the sliding rod 13. The spring 15, using its elasticity, can push the knob 16, keeping the locking block 14 engaged with the locking groove 11.

[0035] Reference Figure 1 , Figure 2 and Figure 5The external of the housing 1 is fixedly connected to a discharge port 17, which is used to discharge larger materials remaining on the screen plate 2 after screening. The external of the housing 1 is also fixedly connected to a discharge port 18, which is used to discharge smaller materials falling after screening by the screen plate 2. Fixed plates 21 are fixedly connected to both sides of the interior of the housing 1. The bottom of the screen plate 2 contacts the groove of the fixed plate 21. The groove of the fixed plate 21 supports and limits the screen plate 2, preventing it from moving laterally. The bottom of the housing 1 is also fixedly connected to... There is a second spring 19, which can buffer the impact force generated when the box 1 vibrates. The bottom of the second spring 19 is fixedly connected to a support frame 20, which provides stable support for the rotating screen. The bottom of the box 1 is fixedly connected to a motor base plate 22. Two vibrating motors 23 are fixedly connected to the outside of the motor base plate 22. The motor base plate 22 provides mounting points for the vibrating motors 23. The vibration generated by the vibrating motors 23 is transmitted to the box 1 through the motor base plate 22, causing the box 1 to drive the screen plate 2 to vibrate in order to achieve material screening.

[0036] Working principle: Align the mounting plate 3 with the groove on the housing 1. The sliding rod 13 is then inserted into the slot 11. By pressing and rotating the knob 16, the spring 15 is compressed, simultaneously causing the sliding rod 13 and the locking block 14 to insert into the slot 11. This engages the locking block 14 with the slot 11, thus fixing the mounting plate 3 to the outside of the housing 1. The mounting shell 4 is fixed to the outside of the mounting plate 3. Therefore, the cylinder 5 inside the mounting shell 4 contracts, driving the connecting block 6, which in turn drives the rotating plate 7. The other end of the rotating plate 7 is rotatably connected to the fixed block 10, thus the rotating plate 7 drives... Pressing block 9 contacts screen plate 2, thereby fixing screen plate 2 on fixed plate 21 inside box 1. When the vibration motor 23 at the bottom of fixed plate 21 drives box 1 to vibrate, spring 19 at the top of support frame 20 provides support and buffer, so that screen plate 2 inside box 1 vibrates to screen materials. The screened material is discharged through discharge port 18, while the material on screen plate 2 is discharged through discharge port 17. Therefore, pressing block 9 driven by cylinder 5 fixes screen plate 2 inside box 1, preventing screen plate 2 from shifting due to vibration, thereby affecting the screening effect of screen plate 2.
