Durable vibration material feeding device

Abstract

The invention discloses a durable vibration material feeding device which comprises a vibration motor and further comprises a lower body, a lifting arm mechanism, an upper body, a pressing bar and a soft connection skin, wherein the lifting arm mechanism comprises lifting arms, upper hinge bolts, upper rubber springs, lower hinge bolts and lower rubber springs; the vibration motor is connected with the lower body; the upper rubber springs and the lower rubber springs are all annular pieces; and the upper hinge bolts penetrate through the upper rubber springs. The durable vibration material feeding device has the beneficial effects that according to the new technical scheme, by the improvement of the lifting arm structure, the stress conditions of the rubber springs are improved, the reliability of a vibration hopper is enhanced, the possibility of a quality accident is decreased, the time for replacing the lifting arms is shortened, and the service lives of the lifting arms and the vibration hopper are prolonged; and the durable vibration material feeding device has certain economical and social benefits.

Description

technical field [0001] The invention relates to mining machinery, in particular to a vibration feeding hopper device with long service life. Background technique [0002] Vibrating feeding hopper is a kind of equipment with three functions of arch breaking, feeding and closing. It is widely used in coal, electric power, machinery, chemical industry, building materials, metallurgy, mining, light industry, food, food, medicine, transportation, etc. Under the bulk material silo of the department. [0003] The boom of the prior art is mainly made up of suspension rod, rubber spring, gland. The upper body of the hopper and the lower body of the hopper are flexibly connected through the boom. The boom is subjected to longitudinal load through the pre-compression fastening of the rubber spring and the boom. The vibration of the vibration motor realizes vibration feeding through the resonance motion of the rubber spring. When the hopper is working, several booms in a circle rotate...

AI Technical Summary

Problems solved by technology

When the hopper is working, several booms in a circle rotate with the ellipse of the hopper. Due to the irregularity of vibration, the rubber spring in the existing boom is subjected to torsion and friction. , so that the force of the rubber spring deteriorates and it is easy to fail

Speed ​​up the process of failure, so that the vibration hopper has quality problems, especially for large hoppers.
