Description

Technical Field

[0001] The utility model belongs to the field of vibrating operating machinery, and mainly relates to a vibrating body equipped with a feeding buffer elastic device of a feeding box of a vibrating screen or a feeding trough of a vibrating feeder. Background Art

[0002] The feed box of the existing vibrating screen or the trough of the vibrating feeder is a metal rigid structure with a wear-resistant lining installed on the inner side of the rigid body and the contact surface with the material. During operation, it vibrates with the main body, and the material also vibrates and runs with it. When there are large pieces of material impact or heavy-loaded mineral materials, this structure has the following disadvantages: due to the direct impact of large pieces of mineral materials on the rigid feed box or trough, it often cracks and breaks, and the wear-resistant lining often loosens, falls off and is damaged. When operating with thick material layers and heavy-loaded mineral materials, relying solely on the vibration force of the main machine, the loosening of the material and the weakened conveying capacity cause the material running speed to slow down, the material to pile up, and the machine body to be crushed. If you want to change this phenomenon, you can only increase the vibration force of the main machine, which in turn increases the kinetic energy consumption of the work, and at the same time increases the destructive force of the machine body. Summary of the invention

[0003] The utility model aims to provide a vibrating body equipped with an elastic device for feeding buffer, which can be applied to a vibrating screen or a vibrating feeder to achieve efficient and energy-saving screening or transportation of materials.

[0004] The utility model is realized by the following technical scheme, including a frame, a vibration source, a main engine damping spring and an elastic device; the frame includes side plates, a bracket crossbeam, a rear baffle and a vibration source mounting frame; the vibration source is mounted on the vibration source mounting frame, and the frame is connected to a support seat through a main engine damping spring, and is characterized in that: the elastic device is located on the bracket crossbeam, and includes a rubber spring, a floating chassis and a bottom lining plate; the bracket crossbeam is located between the two side plates of the frame, a floating chassis is installed on the bracket crossbeam through a rubber spring, and a bottom lining plate is installed on the floating chassis; side surrounding vertical lining plates are installed on the inner sides of the two side plates and the rear baffle of the frame; the elastic device is located at the feeding end of the frame, and the length is equal to 0.5 to 1.5 meters, or is located between the feeding end and the discharging end of the frame, and the overall length along the material flow direction.

[0005] The floating chassis installed on the bracket crossbeam is an integrally welded rigid bracket structure, and the rubber springs under the floating chassis are evenly arranged on the bracket crossbeam.

[0006] The bottom lining is divided into unit blocks and installed in parallel on the floating chassis; the material used for the bottom lining is metal material, rubber material, polyurethane material or ceramic rubber composite material.

[0007] The structure of the support seat 11 is a seat structure or a hanging structure.

[0008] The beneficial effect of the utility model is that the floating chassis equipped with the bottom lining plate generates secondary vibrations at the same time as the main machine excitation source vibrates once under the action of the rubber spring. The kinetic energy consumption is reduced, the amplitude is amplified, and the movement and loosening of materials are quickly promoted. It can also withstand the impact of heavy loads and large pieces of materials, and extend the service life of the vibrating body. The length of the elastic device can be determined according to the needs of different vibrating bodies. When used for a vibrating screen, the elastic device is located 0.5 to 1.5 meters from the feeding end of the screen frame; when used for a vibrating feeder, the elastic device is located at the entire length of the trough frame along the material flow direction. The sub-unit arrangement of the bottom lining plate facilitates the disassembly, assembly and replacement of the bottom lining plate. It is suitable for vibrating screening machinery or vibrating material conveying machinery. BRIEF DESCRIPTION OF THE DRAWINGS
