Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a schematic view of the structure of the spiral sand washer of the present invention. As shown in FIG. 2, the screw sander of the present invention comprises a screw shaft 1, a head bearing block 2 and a tail bearing block assembly 4. Fig. 3 is a front view of the mounting mechanism structure of the tail bearing block assembly, and fig. 4 is a left side view of fig. 3, and as shown in fig. 3 and 4, the tail bearing block assembly 4 comprises a tail bearing block 5, a lead screw 6 and

suspension handles

71 and 72; a connecting plate 51 is fixed on the tail bearing block 5, and the connecting plate 51 is hinged with the lower end of the screw rod 6; the upper portion of the lead screw 6 is connected with a thrust bearing 8, a lead screw nut 9 matched with the lead screw 6 is connected to the upper portion of the thrust bearing 8, the

hanging handles

71 and 72 are fixed on the lead screw nut 9, and the

hanging handles

71 and 72 are symmetrically fixed on two sides of the lead screw nut 9.

The working principle is as follows:

according to the spiral sand washer, the tail bearing seat 5 is hinged with the screw rod 6 through the connecting plate 51, the upper portion of the screw rod 6 is connected with the thrust bearing 8, and the thrust bearing 8 is further connected with the screw rod nut 9 matched with the screw rod 6, so that the tail bearing seat 5 is hung. When the screw shaft is in work, the driving device 2 drives the screw shaft 1 to rotate, when two ends of the screw shaft 1 are not concentric, the flexible force generated by rotation acts on the tail bearing seat 5, the tail bearing seat 5 can swing left and right relative to the drawing 3 because the tail bearing seat 5 is hinged with the screw rod 6, and the screw rod 6 can drive the tail bearing seat 5 to rotate horizontally because the upper part of the screw rod 6 is connected with the thrust bearing 8. Moreover, when the tail bearing seat 5 and the head bearing seat 3 are not concentric in the horizontal direction, the tail bearing seat and the head bearing seat can be concentric in the horizontal direction by rotating the lead screw 6; in addition, the tail bearing seat 5 can flexibly move in a small range in a three-dimensional space relative to the head bearing seat 3, so that the bearings and the bearing seats are not damaged by flexible force when the screw shaft 1 rotates, and the service life of the screw shaft 1 is prolonged.

Preferably, the connecting plate 51 is provided with a pin shaft hole 52; the lower end of the screw rod 6 is provided with a through hole 61, and the pin shaft hole 52 and the through hole 61 are penetrated with a pin shaft 10 to hinge the screw rod 6 and the connecting plate 51. The hinge pin is hinged, so that the structure is simple and the installation is convenient.
