Shaft head component of screw sand washer

A shaft head component of a screw sand washer comprises a shaft head, a bearing component and a sealing component. The bearing component is fixedly connected to the shaft head; the sealing component comprises a sealing seat, sealing packing, a top cover and a rubber plate component; the sealing seat is fixedly connected to the shaft head through a shaft sleeve; the sealing packing is arranged on the front side of the sealing seat and between the sealing seat and the shaft sleeve; the rubber plate component is fixedly connected to the rear side of the sealing seat; the top cover is fixedly arranged at one end of the sealing seat and closely contacts with the sealing packing. The shaft head component of the screw sand washer has the advantage that, by triple sealing through the sealing packing, the sealing seat and the rubber plate, water in the sand washer is prevented from flowing out from a tank wall through the shaft head component. 种螺旋洗砂机的轴头组件，包括轴头、轴承组件和密封组件，轴承组件固定连接在轴头上，密封组件包括密封座、密封盘根、顶盖和橡胶板组件；密封座通过轴套固定连接
