Detailed Implementation

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] like Figures 1 to 4 As shown, this embodiment of the utility model provides a quick-assembly and disassembly sieve structure, including:

[0032] The sieve body 1 has sieve holes 2 evenly distributed in the middle of the sieve body 1, and the four corners of the bottom of the sieve body 1 are fixedly connected with insert rods 3.

[0033] The support plate 4 has four corner holes 5 that mate with the insertion rod 3. The two ends of the bottom of the support plate 4 are fixedly connected to the support plate 6.

[0034] Positioning component 7 is assembled between two support plates 6 and is used to cooperate with the insertion rod 3 to position the screen body 1.

[0035] In this embodiment, buffer grooves are provided at all four ends of the top of the support plate 4. A magnetic sheet is fixedly connected to the bottom of the buffer groove. The buffer groove is filled with a noise reduction pad 18. A metal sheet is provided inside the noise reduction pad 18, and the metal sheet is magnetically connected to the magnetic sheet. By setting the buffer groove, the noise reduction pad 18 can be hidden. With the setting of the magnetic sheet, the noise reduction pad 18 can be magnetically positioned after it is placed in, ensuring the stability of the noise reduction pad 18. When the screen body 1 is placed on the support plate 4, the collision between the screen body 1 and the support plate 4 can be buffered by the noise reduction pad 18. The material of the noise reduction pad 18 can be rubber.

[0036] In this embodiment, the positioning component 7 includes:

[0037] Two guide plates 8 are slidably connected to the two support plates 6 on the side close to each other. Each guide plate 8 has a linkage rod 9 rotatably connected to both ends. The four corners of the bottom of the bearing plate 4 are slidably connected to displacement frames 10. The end of the displacement frame 10 close to the insertion rod 3 is fixedly connected to a locking rod 11, and the locking rod 11 is engaged with the corresponding insertion rod 3.

[0038] In this embodiment, a linear groove is provided on the side of the two support plates 6 that are close to each other. A linear slider is fixedly connected to the side of the guide plate 8 that is close to the support plate 6, and the linear slider is also slidably connected inside the linear groove. Through the structural cooperation of the linear groove and the linear slider, the vertical displacement of the guide plate 8 can be effectively guided vertically, so as to avoid the uncontrollable displacement of the guide plate 8.

[0039] In this embodiment, both ends of the bottom of the support plate 4 are provided with linear guide grooves, and the top of the displacement frame 10 is fixedly connected with a linear guide block, which is also slidably connected in the linear guide groove. Through the setting of the linear guide groove and the linear guide block, the displacement of the displacement frame 10 can be effectively guided, and the displacement frame 10 can be prevented from undergoing uncontrollable displacement.

[0040] In this embodiment, the guide plate 8 has an L-shaped structure, and both ends of the guide plate 8 are provided with support plates for supporting the insertion rod 3. Through the structural characteristics of the guide plate 8, the linkage rod 9 can be stably assembled between the displacement frame 10 and the guide plate 8. With the support plates, when the guide plate 8 is moved to the bottom of the insertion rod 3, as the guide plate 8 continues to move, it can push the insertion rod 3 with the help of the support plates, causing the screen body 1 to separate from the bearing plate 4.

[0041] In this embodiment, stabilizing light rods are fixedly connected to both ends of the guide plate 8 and one side of the displacement frame 10, and the linkage rod 9 is rotatably connected between the two corresponding stabilizing light rods. By setting the stabilizing light rods, the linkage rod 9 can be effectively assembled to ensure the connection effect of the linkage rod 9 between the guide plate 8 and the displacement frame 10.

[0042] In this embodiment, a locking hole is provided on the side of the insertion rod 3 near the locking rod 11, and the locking rod 11 is snapped into the locking hole. By setting the locking hole, when the locking rod 11 moves towards the insertion rod 3, the locking rod 11 can be moved into the locking hole, thereby positioning the screen body 1 by locking the insertion rod 3.

[0043] The central shaft 12 is rotatably connected between two support plates 6. Both ends of the top of the central shaft 12 are fixedly connected to eccentric plates 13. The bottom end of the guide plate 8 is fixedly connected to a linkage plate 14. A linkage slot 15 is opened in the middle of the linkage plate 14, and the ends of the two eccentric plates 13 away from the central shaft 12 are respectively movably connected to the inside of the two linkage slots 15.

[0044] The transmission screw 16 is rotatably connected to one end of the bottom of the bearing plate 4. A displacement ear 17 is fixedly connected to the guide plate 8 near the transmission screw 16, and the displacement ear 17 is also threaded to the outside of the transmission screw 16.

[0045] In this embodiment, support holes are provided at the bottom ends of the two support plates 6 that are close to each other, and the central shaft 12 is connected between the two support holes by ball bearings. The support holes can effectively support both ends of the central shaft 12, and the ball bearings can ensure the smooth rotation of the central shaft 12.

[0046] In this embodiment, a linkage pin is fixedly connected to one end of the eccentric plate 13 away from the central shaft 12, and the eccentric plate 13 is movably connected to the inside of the linkage slot 15 through the linkage pin. With the linkage pin, when one of the guide plates 8 moves down, the linkage pin can be pressed by the linkage plate 14, thereby driving the eccentric plate 13 to rotate under the support of the central shaft 12.

[0047] In this embodiment, a force-bearing knob is fixedly connected to the bottom end of the transmission screw 16, and the outer side of the force-bearing knob is provided with anti-slip texture. The force-bearing knob allows personnel to easily rotate the transmission screw 16.

[0048] Working principle: The support plate 4 is positioned at the screening position of the screening device by means of tools or welding. Then, the insertion rod 3 is aligned with the insertion hole 5, and the screen body 1 is pushed. At the same time, the insertion rod 3 passes through the insertion hole 5, and the screen body 1 reaches above the support plate 4 to wait for positioning.

[0049] Rotating the transmission screw 16, with the transmission screw 16 connected to the displacement ear 17, allows the displacement ear 17 to drive the guide plate 8 connected to it to move along the transmission screw 16. At the same time, the linkage plate 14 at the displacement guide plate 8 presses the eccentric plate 13. Since the eccentric plate 13 is supported by the central shaft 12, it can drive the central shaft 12 to rotate, and through the central shaft 12, it can drive the other eccentric plate 13 to rotate synchronously, so that the two guide plates 8 are moved synchronously. Since the linkage rod 9 is connected between the guide plate 8 and the displacement frame 10, when the guide plate 8 is moved, it can pull the displacement frame 10 through the linkage rod 9, causing the locking rod 11 to approach the insertion rod 3 until the locking rod 11 is engaged with the insertion rod 3, thereby locking the position of the screen body 1.

[0050] Furthermore, when it is necessary to replace the screen body 1, rotating the transmission screw 16 drives the two guide plates 8 to move upward synchronously, causing the locking rod 11 to disengage from the insertion rod 3. Then, continuously rotating the transmission screw 16 drives the guide plates 8 to move upward continuously, so as to push the insertion rod 3 through the guide plates 8, causing the screen body 1 to separate from the bearing plate 4, so that personnel can hold the screen body 1.

[0051] When the coal raw material to be screened reaches above the screen body 1, it can be screened through the screen holes 2.

[0052] As can be seen from the above description, the above embodiments of this utility model achieve the following technical effects: by combining the screen body 1 and the bearing plate 4, and by locking the insert rod 3 with the help of the locking rod 11, the application stability of the screen body 1 can be ensured, and the screen body 1 can be quickly replaced when damaged, which greatly improves the overall convenience.

[0053] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
