Description

Technical Field

[0001] The utility model relates to the technical field of plane screening, in particular to a plane screening grading mechanism. Background Art

[0002] In the process of screening materials, they are generally separated by a screening structure, and the principle is to make the screening net vibrate so that the material on the upper end automatically falls through the mesh of the screening net during the movement to complete the screening process. However, the existing plane screening and grading mechanism still has certain use defects during use, such as:

[0003] The invention announcement number CN114733751B discloses a mechanical vibration fine screening classifier, in which the material to be screened is thrown into the screen bucket, and under the resetting action of the vibration frame, the screen bucket reciprocates and vibrates for screening, part of the material is retained in the screen bucket, and the other part falls into the feed hopper, and falls to the first screen frame structure along the feed hopper, and at the same time, the first motor drives the second slot plate to rotate around the transmission mechanism, and the second slot plate drives the second screen frame structure to reciprocate along the slide frame, and under the reversing transmission action of the transmission mechanism, the first slot plate drives the first screen frame structure to reciprocate for screening, and the material screened by the first screen frame structure is screened and layered by the second screen frame structure. The device is convenient for quickly completing multi-stage screening of materials and classified collection. During the movement of the first screen frame structure and the second screen frame structure, when the fixed block and the weight block squeeze each other, the weight block drives the sealing plate to rotate, and under the action of inertia, the material slides out of the first screen frame structure and the second screen frame structure, which is convenient for taking out the screened material;

[0004] In the above document, during the movement of the classifier, the movement of the two groups of screening plates needs to be completed by the rotation of the first slot plate and the second slot plate, and during the rotation of the first slot plate and the second slot plate, the first slot plate and the second slot plate need to be driven by the motor at the middle position of the first slot plate and the second slot plate to rotate, and the rotation of the first slot plate and the second slot plate will cause their upper ends to rotate and provide power for the movement of the two groups of screening plates, and the motor will drive the first slot plate and the second slot plate to move through the connecting plate, and the rotation of the first slot plate and the second slot plate will make the linear speeds at different positions different, and the reciprocating speeds of the two groups of screening plates are different during the movement, which may easily lead to increased wear of the two groups of screening plates during acceleration and deceleration, affecting the normal movement of the two groups of screening plates, and easily affecting the service life of the classifier.
