How To Reduce The Vibration Of The Whole Machine By Installing a Weight Buffer Mechanism At The Bottom Of The Apron Feeder

At present, apron feeder chain plate is usually equipped with multiple sets of support wheels supporting the chain plate in the return journey of the operation process, and these support wheels are usually fixed on the beam of the rack. The chain plate will repeatedly impact the support wheel of the head during the movement of the chain plate, resulting in damage to the chain plate or the support wheel, and the beam supporting the support wheel will beat repeatedly for a long time.

The technical problem we solved is to overcome the existing defects and provide a heavy plate buffer mechanism for the support wheel at the bottom of the mining machine, so that the support wheel has a buffer effect when the chain plate is repeatedly hit, reduce the damage of the chain plate or the support wheel, make the support wheel stable to provide support for the chain plate, reduce the working resistance of the chain plate, and avoid the cross beam of the support wheel to repeatedly beat and cause damage and deformation. Can effectively solve the problem of apron feeder machine vibration. In order to achieve the above purpose, the following technical scheme is provided: A buffer mechanism for the bottom support wheel of a heavy plate miner, including a support wheel, both ends are respectively fixed connected with an end shaft, and the two end shafts are respectively connected with a mounting block through a bearing rotation: The arc buffer unit comprises a circular groove body, a sector slide block, an arc slide column and a spring. The two mounting blocks are respectively fixed and connected with a sector slide block on one side away from the support wheel. The two sector slides are respectively connected with two circular groove bodies, and an arc slide column is arranged in the two circular groove bodies respectively. Each circular slide column is separately connected with a spring on both sides of the sector slide block: The transverse buffer unit is provided with two and is respectively installed on the side of the two circular groove bodies away from the support wheel, and the side of the two horizontal buffer units away from the support wheel is respectively connected with the beam by a fixed component. The transverse buffer unit is installed on the inner side of the beam through a fixed component. The transverse buffer unit can buffer the transverse impact force suffered by the support wheel to avoid excessive damage to the support wheel or chain plate. When the support wheel is vertically impacted, the fan-shaped sliders at both ends of the support wheel slide along the arc slide column in the circular groove body, and the extruded spring can play a buffer role. Thus the cushioning effect on the support wheel is realized and the cushioning and protection effect on the support wheel is improved. The arc buffer unit also comprises a mounting nut, and the two ends of the arc slide column extend to the outer ends of the arc groove body and are respectively threaded with mounting nuts. The mounting nuts fix the two ends of the arc slide column on the outer ends of the arc groove body to achieve the position fixing effect of the arc slide column, and it is convenient to remove the arc slide column from the arc groove body after removing the mounting nut. The transverse buffer unit comprises a u-shaped mounting frame, a transverse slide column, a buffer slide block and a transverse buffer spring, the inner side of the u-shaped mounting frame is fixed connected with a transverse slide column, the middle of the transverse slide column is sliding connected with a buffer slide block, the two ends of the transverse slide column are respectively connected with a transverse buffer spring, the side of the buffer slide block is fixed connected with a circular groove body away from the side of the support wheel.

When the apron feeder support wheel is subject to the transverse impact force, the buffer slider slides along the transverse slide column through the transmission function of the mounting block and the curved buffer unit, which will compress the transverse buffer spring on the side of the activity direction of the buffer slider, and the buffer function of the transverse buffer spring can buffer and protect the support wheel.
