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.

[0035] like Figure 1 - Figure 4 As shown, this utility model provides a technical solution: a rapid screen changing vibrating screen, including: a screening chamber 1 and a chamber cover 7 placed on top of the screening chamber 1;

[0036] Screening assembly 11 is placed inside screening chamber 1. Screening assembly 11 includes a fixing ring 111 disposed inside screening chamber 1. Each fixing ring 111 has a snap-fit block 113 disposed on its outer side. The inner wall of the fixing ring 111 near the snap-fit block 113 is provided with a fixing ring groove 114. A screen 112 is disposed inside the fixing ring 111. The screen 112 is fixed inside screening chamber 1 by the fixing ring 111, the snap-fit block 113 on its outer side, and the fixing ring groove 114 on its inner wall. When in use, the material enters screening chamber 1 and falls onto the screen 112. Under the action of external forces such as vibration, the material smaller than the aperture of the screen 112 falls through the screen 112, while the material larger than the aperture of the screen 112 remains on the screen 112, thereby achieving the effect of screening the material according to particle size.

[0037] A blower assembly 10 is placed inside the compartment cover 7. The blower assembly 10 includes a support box 101 fixed to the bottom of the compartment cover 7. The support box 101 has an exhaust port 102. A connecting shaft 104 is rotatably connected inside the support box 101. A first motor 103 is fixed to the connecting shaft 104. A support shell 106 is fixed to the bottom of the first motor 103. A blower fan 107 is installed inside the support shell 106. A second motor 105 is fixed to one end of the connecting shaft 104. The support box 101 is fixed to the bottom of the compartment cover 7, and the exhaust port 102 is located on it. The air outlet 102 is used for air outlet. The connecting shaft 104 inside the support box 101 is driven to rotate by the first motor 103. The second motor 105 at one end of the connecting shaft 104 can adjust the air blowing direction. A blower 107 is installed in the support shell 106 at the bottom of the first motor 103. When the first motor 103 starts, it drives the blower 107 to rotate and generate airflow. The airflow is blown out through the exhaust port 102, which can blow the material in the screening chamber 1, such as blowing away material clumps. The second motor 105 can control the air blowing direction to ensure that the blowing effect is uniform and effective.

[0038] Furthermore, such as Figure 1 - Figure 3 As shown: Each side of the fixing ring 111 near the fixing ring slot 114 is fitted with a fixing block 115. The top of the fixing block 115 is provided with a dustproof net 116, and the fixing block 115 is provided with a fixing screw 117. The fixing ring 111 is fitted with the fixing block 115 through the fixing ring slot 114. The fixing block 115 has a dustproof net 116 and a fixing screw 117. In use, the dustproof net 116 can prevent dust from entering the screen 112 or internal materials from falling into the locking groove 14. The fixing screw 117 ensures that the fixing block 115 is stable and ensures the screening effect.

[0039] The above solutions also have the problem of difficult equipment disassembly, such as... Figure 4 As shown: In this scheme, the connecting component 8 includes a connecting plate 81, on which a connecting plate slot 82 is provided. A snap-fit plate 83 is fixed on one side of the bin cover 7. The snap-fit plate 83 is snapped into the connecting plate 81 through the connecting plate slot 82. The connecting plate 81 in the connecting component 8 has a connecting plate slot 82. The snap-fit plate 83 on the bin cover 7 cooperates with the slot to snap into place. In use, the snap-fit plate 83 is inserted into the connecting plate slot 82 to make the bin cover 7 tightly connected to the screening bin 1, which enhances the overall structural stability of the device, prevents the bin cover 7 from shaking or shifting, and ensures the safety and reliability of the device operation. It also facilitates the installation and disassembly of the bin cover 7, and makes it convenient to inspect and maintain the inside of the device.

[0040] Working principle: such as Figure 1 - Figure 4 As shown, in the screening assembly 11, the fixing ring 111 securely fixes the screen 112 in the screening chamber 1 with the help of the snap-fit block 113 and the fixing ring slot 114. When the material enters the screening chamber 1, it falls onto the screen 112. Under the action of vibration, the material smaller than the aperture of the screen 112 passes through the screen 112, while the material larger than the aperture remains on the screen 112, thus achieving the effect of screening materials according to particle size. The fixing snap-fit block 115 on the fixing ring 111 is fixed by the fixing screw 117. Its dustproof net 116 can block dust from entering the screen 112 and prevent internal materials from falling into the snap-fit slot 14, ensuring screening accuracy and screen 112 life. The snap-fit slot 14 of the screening chamber 1 is engaged with the snap-fit block 113 to ensure that the screening assembly 11 is installed firmly and is easy to operate.

[0041] In the blowing assembly 10, the support box 101 is fixed to the bottom of the bin cover 7, and the exhaust port 102 is used for air outlet. The first motor 103 drives the connecting shaft 104 to rotate, which drives the blower 107 in the support shell 106 to generate airflow and blow it out from the exhaust port 102, which can disperse material clumps. The second motor 105 adjusts the direction of the connecting shaft 104 to ensure that the blowing is uniform and effective, and improves the quality of material processing.

[0042] The connecting plate 81 of the connecting component 8 has a connecting plate slot 82, which is snapped into the snap-fit plate 83 of the bin cover 7, so that the bin cover 7 is tightly connected to the screening bin 1, which enhances the overall structural stability, prevents shaking and displacement, ensures safe and reliable operation, and facilitates the installation and disassembly of the bin cover 7 for internal inspection and maintenance.

[0043] The guide chamber 2 receives the screened material. The material enters through the top inlet 9 and is guided by the bottom guide plate 12 to the outlet 3, achieving orderly discharge and improving discharge efficiency and stability. The damping spring 13, support plate 6 and support ring 5 inside the protective shell 4 work together to buffer the vibration of the device during operation, provide stable support, reduce shaking, ensure smooth operation of the device, and extend its service life.

[0044] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
