Detailed Implementation

[0023] 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.

[0024] Please see Figures 1 to 6 This utility model provides a technical solution: a high-efficiency material screening component, including a material screening device body 100, the material screening device body 100 including a fixed base 101, a screening box 102 is spring-loaded onto the upper surface of the fixed base 101, a vibration motor 103 is fixed at the middle position of the lower surface of the screening box 102, two screening screens 108 are fixedly installed inside the screening box 102, a feed hopper 104 is fixed at the top of the screening box 102, a discharge port 105 and a discharge port 3 107 are fixed at the top and bottom of one side of the screening box 102 respectively, a discharge port 2 106 is fixed at the middle position of the other side of the screening box 102, and the material screening device body 100 is also provided with:

[0025] The crushing and conveying mechanism includes a fixed mounting component disposed on one side of the fixed base 101. The fixed mounting component contains a conveying component, and the conveying component contains a crushing component. After screening, the material screening device body 100 discharges large materials through the discharge port 105 into the crushing and conveying mechanism for crushing and conveying. This facilitates one-time screening, is simple and convenient to operate, and allows for faster screening.

[0026] In order to facilitate the fixed installation of the feed box 1023 and the conveying pipe 1024 through the fixed installation assembly, and to ensure that the vibration of the screening box 102 is not affected during use after installation, in this embodiment, preferably, the fixed installation assembly includes a fixed bracket 1021 welded and fixed to one side of the fixed base 101, and a fixed ring 1022 welded and fixed to the top of the fixed bracket 1021. The conveying pipe 1024 can be fixedly installed inside the fixed ring 1022, thereby facilitating installation and use.

[0027] To facilitate the re-lifting of crushed material to the screening box 102 for further screening via the conveying assembly, in this embodiment, preferably, the conveying assembly includes a conveying pipe 1024 bolted to the inside of a fixing ring 1022. A flexible corrugated pipe 1025 is screwed to the top of the conveying pipe 1024 and the top of the screening box 102. The flexible corrugated pipe 1025 facilitates feeding and prevents the end of the conveying pipe 1024 from affecting the screening box 102 during vibratory screening. A screw conveyor 1027 is installed inside the conveying pipe 1024 via a main motor. A feed box 1023 is fixed to the upper surface of the bottom end of the conveying pipe 1024. The upper surface of 23 corresponds to the bottom end of the discharge port 105, and the bottom end of the flexible corrugated pipe 1025 is fixedly installed with a rubber protective plate 1026 at the connection between the top end of the feed box 1023 and the bottom end of the feed box 1025. When the screening box 102 drives the discharge port 105 to vibrate, the rubber protective plate 1026 deforms and moves accordingly, and it is not easy to affect the vibration screening of the screening box 102 and the discharge port 105. Large materials after screening can be crushed in the feed box 1023 and then enter the interior of the conveying pipe 1024. Inside the conveying pipe 1024, the material is conveyed by the rotation of the screw conveyor 1027 through the flexible corrugated pipe 1025 into the interior of the screening box 102, which is convenient for conveying and screening again.

[0028] In order to facilitate the crushing of large materials after screening into the feed box 1023 through the crushing assembly, in this embodiment, preferably, the crushing assembly includes two crushing rollers 1028 rotatably connected to the bottom of the feed box 1023 via bearings. Gears 1029 are installed on the end surfaces of the crushing rollers 1028 inside the feed box 1023, and the two gears 1029 mesh with each other. A drive motor 1020 is fixedly installed on the end of the crushing rollers 1028 on the outer surface of the feed box 1023. When the drive motor 1020 is running, it drives the gears 1029 to rotate, and the meshing rotation of the two gears 1029 drives the two crushing rollers 1028 to rotate in opposite directions to crush the large materials.

[0029] The feeding mechanism includes a uniform feeding component located at the bottom of the feeding hopper 104. During the feeding and screening process, after the material is fed into the feeding hopper 104, the uniform feeding mechanism ensures that the material is evenly fed into the surface of the screening screen 108 for vibration screening, which facilitates screening and prevents accumulation that could cause damage due to gravity.

[0030] In order to facilitate uniform feeding of material into the surface of the screening screen 108 from inside the feed hopper 104 by the partitioned uniform feeding component, and to prevent excessive accumulation of material on the surface of the screening screen 108 at one feeding, causing heavy pressure, in this embodiment, preferably, the partitioned uniform feeding component includes a partition plate 1041 welded and fixed to the bottom of the inside of the feed hopper 104, and a partition hole 1042 is formed at the connection of the two partition plates 1041. When feeding into the inside of the feed hopper 104, the material can be separated by the partition hole 1042, and after being separated by the partition hole 1042, the material can be guided evenly into the surface of the screening screen 108 through the partition plate 1041, which facilitates uniform feeding and screening and prevents accumulation.

[0031] The working principle and usage process of this utility model are as follows: Before use, the main body 100 of the material screening device is stably placed in the position of use by fixing the base 101. After the main body 100 of the material screening device is stably placed, when screening the material, the material is directly fed into the screening box 102 through the feed hopper 104 and enters the surface of the screening screen 108. The vibration motor 103 drives the screening box 102 and the screening screen 108 to vibrate and screen the material inside. The screened material is discharged through the discharge port 105, discharge port 206 and discharge port 307 in sequence to discharge the screened material of each layer inside.

[0032] Then, after the material screening device 100 performs screening, the large particles screened out by the screening screen 108 at the top of the screening box 102 are discharged directly into the feed box 1023 through the discharge port 105. After entering the feed box 1023, the drive motor 1020 drives the gear 1029 and the crushing roller 1028 to rotate, so that the two gears 1029 mesh and rotate, driving the two crushing rollers 1028 to rotate in opposite directions to crush the large materials after screening and enter the conveying pipe 1024. The main motor drives the screw conveyor 1027 to rotate again, conveying the crushed materials to the top through the flexible corrugated pipe 1025 into the top of the screening box 102, which is convenient for screening again and for the cyclic crushing and screening of large materials. The screening process is completed in one go. The operation is simple and convenient, the screening process is faster, and the convenience of crushing and conveying large materials by the material screening device 100 during the material screening process is improved.

[0033] Finally, after the material screening device body 100 feeds material into the screening box 102 through the feed hopper 104 during screening, and the material enters the feed hopper 104, it is again guided into the partition hole 1042 through the partition plate 1041 to different positions on the upper surface of the screening screen 108. This makes it easier to prevent material from accumulating on the surface of the screening screen 108 during feeding, thus preventing the surface of the screening screen 108 from being damaged by heavy pressure. Uniform feeding ensures that the screening screen 108 is subjected to uniform force and vibrates fully during screening, improving the convenience of uniform feeding into the feed hopper 104 during material screening.

[0034] Although embodiments of the present invention have been shown and described (see the detailed description above), 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.
