AI Technical Summary
When existing mechanical exciters meet the needs of large vibrating screen equipment, the excitation force is insufficient, resulting in a small vibration amplitude and low screening efficiency. The existing eccentric blocks or counterweight blocks are made of carbon steel, which cannot meet the larger ones. Excitation force demand.
The exciter counterweight block adopting an internal and external combination structure increases the mass by filling medium with a larger filling density than carbon steel, and uses a fixed structure of the positioning sleeve and positioning column to provide a larger eccentric mass to enhance the excitation force.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of vibration exciters, in particular to a vibration exciter counterweight. Background Art
[0002] The exciter is a device attached to the equipment to generate excitation force and is an important component of mechanical vibration. The exciter can also be used as an excitation component to form a vibration machine to achieve the conveying, screening, compaction, shaping of materials or objects and the tamping of soil and gravel. Existing mechanical exciters generally install eccentric blocks at both ends of the rotating shaft to form an excitation source. During the use of the equipment, in order to meet the needs of different working conditions, the exciter usually has the function of adjusting the excitation force.
[0003] With the development of economy and the innovation of technology, there is a strong market demand for large-scale vibrating screens with large processing capacity, high screening efficiency and reliable operation. Vibrating screen companies will increase their efforts to develop and design heavy and large-scale screening equipment. The weight of the equipment will also increase accordingly. At this time, the exciter needs to have a sufficiently large exciting force to meet the on-site working conditions; the adjustment of the exciting force is usually achieved by changing the eccentric mass or eccentric torque of the eccentric block. There are two main ways to adjust the exciting force: one is to replace the auxiliary eccentric block with the same shape as the eccentric block; the other is to increase or decrease the counterweight block. At present, the material of the existing eccentric blocks or counterweight blocks is generally carbon steel. Due to the design structure of the exciter, even if the number is increased to the maximum, the required exciting force may not be achieved, resulting in a small vibration amplitude of the vibrating screen and low screening efficiency.
