[0047] In this embodiment, the screen 23 is fixed and not easy to shake by the connection between the first box body 21 and the second box body 22. When cleaning or replacement is needed, the screen 23 can be quickly replaced, avoiding the trouble of screwing when replacing the existing screen 23.

[0048] In some embodiments, the first box body 21 and the second box body 22 are arranged in correspondence with each other up and down, and the first driving mechanism 24 is used to drive the second box body 22 to reciprocate up and down relative to the first box body 21 to cover or open the cavity 211, which can fully utilize the longitudinal space of the bracket 10, thereby reducing the space occupied by the vibrating screen 100.

[0049] Of course, in other embodiments, the first box body 21 and the second box body 22 can also be arranged in other positional relationships. For example, the second box body 22 is arranged above the first box body 21 and can move horizontally to open or close the cavity 211. The embodiments of the present application are not limited here.

[0050] In some embodiments, the first driving mechanism 24 includes at least one cylinder 241, which is disposed on the bracket 10, and an output shaft 242 of the at least one cylinder 241 is connected to the second box body 22 to drive the second box body 22 to reciprocate up and down relative to the first box body 21.

[0051] In this embodiment, the telescopic movement of the cylinder 241 is used to achieve the up and down reciprocating movement of the second box body 22 relative to the first box body 21, which has a simple structure and stable operation. Of course, in other embodiments, the first drive mechanism 24 can also adopt other power mechanisms, and this embodiment of the application is not limited here.

[0052] In some embodiments, the first driving mechanism 24 also includes an elastic member 243, which is extended along the movement direction of the second box body 22, and the two ends of the elastic member 243 are respectively connected to the cylinder 241 and the second box body 22, so as to improve the movement stability of the second box body 22 during ascent and descent.

[0053] In some embodiments, a movable gap is provided at the connection between the output shaft 242 of the cylinder 241 and the second housing 22 to prevent the second housing 22 from interfering with the output shaft 242 of the cylinder 241 during vibration.

[0054] In some embodiments, the vibrating screen 100 further includes a guide mechanism, which includes a guide member 41 and a guide groove respectively provided on the first box body 21 and the second box body 22 , and the guide member 41 slides in cooperation with the guide groove along the movement direction of the second box body 22 .

[0055] In this embodiment, the guide member 41 may be a rod-shaped structure, which is slidably matched with the guide groove to guide the movement of the second box body 22 and improve the movement stability of the second box body 22.

[0056] Preferably, two guide mechanisms are provided, which are respectively located on opposite sides of the first box body 21 and the second box body 22 , so as to further improve the movement stability of the second box body 22 .

[0057] In some embodiments, a seal 27 is provided at the joint of the first box body 21 and the second box body 22 so that the first box body 21 and the second box body 22 are tightly connected to prevent water in the screening cavity from leaking from the gap between them.

[0058] In this embodiment, the seal 27 can be made of silicone material with a compressible amount of 3-10 mm. When the second box body 22 is pressed against the first box body 21, the seal 27 is squeezed and deformed to tightly connect the first box body 21 and the second box body 22, further improving the sealing effect of the two.

[0059] Please continue to refer to Figure 4 and Figure 5 The vibrating screen 100 also includes a cleaning mechanism, which includes a cleaning member 51 and a second driving mechanism 52. The cleaning member 51 is arranged in the screening cavity and is located above the screen 23. The second driving mechanism 52 is connected to the cleaning member 51 and is used to drive the cleaning member 51 to reciprocate to clean impurities on the screen 23.

[0060] During the vibration screening process, the cleaning member 51 moves back and forth relative to the screen 23 under the drive of the second driving mechanism 52 to move the material on the screen 23, which can reduce the accumulation of materials, effectively clean the screen 23, and improve the service life of the screen 23 and the screening efficiency of the vibrating screen 100.

[0061] In this embodiment, the reciprocating motion of the cleaning member 51 can be rotational motion or linear motion. For example, the second drive mechanism 52 can be a motor, and the cleaning member 51 is driven by the motor to rotate relative to the screen 23 to clean impurities on the screen 23. Of course, in other embodiments, the second drive mechanism 52 can also be other power mechanisms, and this embodiment of the application is not limited here.

[0062] In this embodiment, the cleaning member 51 may be a brush, which can clean the surface of the screen 23 to reduce the clogging of the screen holes; the brush may adopt a detachable installation structure to facilitate replacement or cleaning of the entire brush.

[0063] In some embodiments, a through hole 221 is provided at the upper end of the second box body 22, and the through hole 221 is connected to the screening cavity;

[0064] The cleaning mechanism also includes a third driving mechanism 53, which is arranged on the bracket 10 and connected to the cleaning member 51 through the transmission member 54 passing through the through hole 221. The third driving mechanism 53 is used to drive the transmission member 54 to drive the cleaning member 51 to move up and down.

[0065] In this embodiment, when the screen 23 needs to be replaced or cleaned, the first drive mechanism 24 drives the second housing 22 to separate from the first housing 21 to expose the screen 23. At the same time, the third drive mechanism 53 drives the transmission member 54 to cause the cleaning member 51 to move away from the screen 23, i.e., move upward, to prevent the screen 23 from interfering with the cleaning member 51 when it is removed. After the screen 23 is replaced or cleaned, the first drive mechanism 24 drives the second housing 22 to engage with the first housing 21. At the same time, the third drive mechanism 53 drives the transmission member 54 to cause the cleaning member 51 to move toward the screen 23, i.e., move downward, to clean impurities on the screen 23.

[0066] In some embodiments, the screen box 20 is provided with at least one observation window 201, which is used to observe the cleanliness of the screen 23. When the screen 23 is blocked or broken, the user can promptly know through the observation window 201 and control the first drive mechanism 24 to drive the second box body 22 to separate from the first box body 21 to clean or replace the screen 23.

[0067] The screen box 20 is provided with at least one discharge port 202, which is used to discharge impurities in the screening cavity. It can realize continuous or intermittent discharge of impurities in the screen box 20 without stopping the machine, which is beneficial to extend the screening time of the vibrating screen 100 and improve the screening efficiency.

[0068] The screen box 20 is provided with at least one flushing inlet 203 , which is located above the screen 23 and is used to inject cleaning liquid into the screening cavity to flush the screen 23 , making it convenient for the user to clean the screen 23 and keep the screen 23 clean.

[0069] Screen box 20 has at least one overflow port 204, located above screen 23. This port is used to drain at least some of the liquid within the screening chamber when the liquid within screen box 20 reaches a predetermined level. If screen 23 becomes clogged, liquid will gradually accumulate on the screen 23 within screen box 20. When the predetermined level is reached, the liquid is discharged through overflow port 204 into an external liquid storage tank, preventing spillage.

[0070] Screen box 20 is provided with at least one exhaust port 205 for exhausting gas from the screening chamber. When vibrating screen 100 is operating, exhaust port 205 is used to exhaust dust and gas generated during the screening process, preventing dust accumulation during the screening process, thereby maintaining a smooth screening process and a safe working environment.

[0071] The above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention may be implemented. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. This list of all possible embodiments is not exhaustive. Any obvious variations or modifications arising from the technical solution of the present invention remain within the scope of protection of the present invention.
