Description

Technical Field

[0001] The utility model mainly relates to the technical field of screening equipment, and particularly relates to a vibrating grading screen for sand making. Background Art

[0002] The vibrating grading screen, i.e., the vibration grading screen, is a machine that uses a vibrating screen surface to classify a mixture of different particle sizes according to particle size. The driving mode of the screen body generally adopts the self-balanced vibration mode, that is, two vibrating motors are symmetrically installed on both sides of the screen ship to drive the screen body. The two motors rotate in opposite directions to cancel the exciting force in the horizontal direction, and the exciting forces in the vertical direction are superimposed to ensure the normal movement trajectory of the screen body and better screening effect.

[0003] At present, the vibrating grading screen has been widely used in many industries such as grain, food, chemical industry, sugar making, mining, etc., and is particularly common in the sand making process. When making sand, a vibrating grading screen is usually used to screen sand and gravel according to particle size. However, the existing vibrating grading screen is inconvenient to use. After screening, it is inconvenient to discharge materials, and the sand and gravel often splash around, making it inconvenient to collect; and when feeding, the sand and gravel often directly pour on the uppermost sieve plate. Due to the relatively large weight of the sand and gravel, long-term concentrated impact on the sieve plate is likely to cause damage to the sieve plate. Therefore, it is necessary to propose an improvement measure to solve the above technical problems.

[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model
