Hydraulic vibrating feeder

Abstract

The invention relates to a hydraulic vibration feeder used for giving-out of materials in a bin, and belongs to the technical field of material conveying equipment. At present, a large number of double-mass near-resonance inertial vibration feeders are used in the metallurgy, mine, coal and other industries, and the problems that in the feeders, a vibration motor and a shearing rubber spring are prone to damage due to combustion under the large feeding amount, online feeding amount adjustment is not easy, and work is not stable exist. A pair of eccentric vibration exciters adopting gear engagement are arranged in a vibration transmission body, a coupler penetrating a hinged hollow pipe is used for connecting one eccentric vibration exciter with a drive motor, the original thickness of a shearing rubber spring at the upper portion of the vibration transmission body is smaller than that of a shearing rubber spring at the lower portion of the vibration transmission body, the radius of theinner circle of the hollow pipe is larger than or equal to 20 times of the work amplitude of the hydraulic vibration feeder, and the shock excitation force acting line generated by a pair of rotationshaft eccentric vibration exciters passes through the gravity center of a groove, it is guaranteed that the hydraulic vibration feeder effectively solves the above problems existing in the feeder, and obvious beneficial effects are achieved.

Description

technical field [0001] The invention relates to a hydraulic vibrating feeder for feeding materials in a silo, and belongs to the technical field of material conveying equipment. Background technique [0002] At present, two-mass near-resonance inertial vibrating feeders are widely used in metallurgy, mining, coal and other industries. This kind of feeder has the advantages of low power consumption and large feeding volume, so it has been used in actual production to a certain extent. However, due to the limited structure of this kind of feeder, it is impossible to adjust the feeding amount of the feeder in real time during the operation of the equipment. Angle or by adjusting the vibration frequency of the vibrator or vibration motor, but the existing structure can not adjust the vibration angle of the tank in real time, because if the vibration frequency is adjusted, it will affect the resonance of the vibrating feeder The working state cannot be realized in practical appl...

AI Technical Summary

Problems solved by technology

However, in the existing structure of the vibration transmission body, the upper and lower shear rubber springs used are the same in size and performance, which makes the stiffness the same. After the equipment is installed, due to the heavy weight of the vibration transmission body itself, the vibration transmission In addition to the pre-tightening pressure in the thickness direction of the shear rubber spring installed at the lower part of the body, it is also subject to the pressure brought by the vibration transmission body's own weight, which leads to inconsistent deformation of the upper and lower shear rubber springs in the thickness direction. The rigidity of the upper and lower shear rubber springs is inconsistent, which causes the vibration direction of the feeder to drift and change during the working process, which seriously affects the stable operation of the feeder

[0010] Due to the above reasons, it is urgent to adopt a new technical solution to solve the problem of online adjustment and stable operation of the two-mass near-resonance inertial vibrating feeder in the case of large feeding volume.
