Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vibrating screens, in particular to a linear vibrating screen. Background Art
[0002] Linear vibrating screen is a screening device that uses vibration motor excitation as the vibration source. Its working principle is that when two vibration motors rotate synchronously in opposite directions, the exciting forces generated by their eccentric blocks cancel each other out in the direction parallel to the motor axis and overlap into a resultant force in the direction perpendicular to the motor axis. Therefore, the motion trajectory of the screen is a straight line. Under the combined effect of the exciting force and the self-weight of the material, the material is thrown up and jumps or moves forward in a straight line on the screen surface, thereby achieving the purpose of screening and grading the material.
[0003] During the use of the existing linear vibrating screen, the screen inside the linear vibrating screen can screen out particles that do not meet the size requirements. If the mesh inside the screen is blocked by particles of the same size, it is easy to affect the screening area and screening efficiency of the screen. It is necessary to suspend the operation of the linear vibrating screen and use manpower to remove the particles blocking the screen, which is easy to reduce the screening efficiency of the linear vibrating screen. To this end, we provide a linear vibrating screen to solve the above problems. Utility Model Content
