        The elastic link conveyor is a near-resonance vibration machine, which uses the rotation of an eccentric shaft (also known as a crank) to drive the vibrating trough to achieve linear reciprocating motion by driving the connecting rod and the main vibration spring to achieve material conveying A kind of vibration conveyor。

        The structure principle of the elastic connecting rod vibration conveyor and the main points of installation and debugging:

1. Structure:

        When the elastic link type vibration conveyor is used as a double-mass body, its structure includes a trough (upper mass), a frame (lower mass), a main vibration spring, a vibration isolation spring, a support spring, and a support swing rod (also known as Guide connecting rod), driving connecting rod, eccentric shaft, motor, pulley and triangle tape.

        The tank and the bracket are respectively supported by a rigid support pendulum rod and a support spring, and are connected by the main vibration spring, the eccentric shaft, and the drive connecting rod to form the excitation force source assembly. The frame is supported by the vibration isolation spring and separated from the foundation. Dual structure.

2. Working principle:

        When the motor is driven by the triangular belt to drive the eccentric shaft to rotate, the drive connecting rod and the main vibration spring are used to excite the vibrating tank body to make a linear reciprocating movement along a certain excitation direction, so as to bring the         animal material and work into a directional throwing motion to achieve vibration The purpose of transportation. Because the vibration         amplitude is a fixed value (that is, the eccentricity of the eccentric shaft), the stability in the vibration state is good, the required excitation force and power consumption are relatively low, and the transmission of the excitation force is stable, which can realize long-distance transportation And many other applications.

3. Installation and debugging
        The elastic link type vibrating conveyor is generally installed horizontally, and can also be installed in an upward or downward tilt, and the inclination angle is not more than 8°.
        When the mechanism is a single body, the installation of the balance weight and the fastening of the foot fasteners should be controlled.
When the mechanism is a double mass body, the installation reliability of the vibration isolation spring and the installation reliability of the connecting rods, the main vibration spring and the supporting swing rod (hinge chain) should be adjusted. All hinge fulcrums, bearing seats, eccentric shafts and other transmission mechanisms should be filled with lithium-based grease.
        There should be a reliable protective cover at the motor and pulley. After the fasteners are fastened and reliable, operation and debugging can be carried out.
        The elastic link type vibrating conveyor should be tested for 2 to 3 hours without load. Observe whether there are any abnormalities or abnormal noises on the moving components, fulcrums, and transmission parts, and check the excitation direction angle, amplitude and vibration noise. The results are all Should meet the design requirements.
