Description

TECHNICAL FIELD

[0001] The utility model relates to mine machinery technical field, concretely for a kind of connecting device for ore vibrating screen material conveyor. BACKGROUND

[0002] The working principle of ore vibrating screen mainly relies on the exciting force generated by vibration motor or vibrator, which makes the screen box and screen surface vibrate at high frequency. After the material falls into the screen box from the feeding end, it quickly advances, loosens and sieves under the action of vibration, completing the screening operation. Specifically, the screen box can make circular motion around the central axis, or reciprocating motion in the horizontal direction, or inclined at a certain angle under the action of gravity and vibration to make the material flow along the screen surface.

[0003] Currently, in the ore processing process, the ore vibrating screen, as a crucial link, generally has a certain vertical distance or drop between the screen mesh and the output end of the material conveyor. This design feature results in that when the ore is unloaded from the output end of the material conveyor, it cannot be smoothly transitioned, but directly impacts and falls on the screen mesh inside the ore vibrating screen in a nearly free-fall manner. This uncontrolled and high-speed impact process not only causes the ore itself to be broken or cracked due to the collision, but more importantly, it brings significant impact force to the screen mesh inside the ore vibrating screen. This continuous and high-intensity impact gradually weakens the strength and durability of the screen mesh, causing wear, deformation or even rupture of the screen mesh, which affects the screening efficiency and quality, increases the cost and frequency of equipment maintenance, and shortens the service life of the screen mesh.

[0010] Further, the length and width of the upper end opening of the cavity are greater than the length and width of the lower end opening, respectively.
