then the tubular shaft 1 drives the radial overturning mechanism 7 to rotate along the circumferential direction of the cylindrical machine shell 9 through the bracket 6, when the transmission gear 73 rotates to the position of the arc-shaped rack 4, the transmission gear 73 and the arc-shaped rack are meshed and connected, so that the transmission gear 73 passively rotates, the transmission gear 73 drives the second bevel gear 74 to rotate, the second bevel gear 74 drives the transmission shaft 75 to rotate through the first bevel gear 72, the transmission shaft 75 drives the support shaft 51 to rotate through the transmission belt 71, so that the holder 56 can overturn along the radial direction of the tubular shaft 1, and the test tube is inverted;
the tubular shaft 1 continues to rotate, and the transverse seat 101 on the rotatable telescopic brush rod 10 can passively move upwards along with the convex sliding of the cam ring 3, so that the rotatable telescopic brush rod 10 can automatically and gradually extend into a test tube to comprehensively clean the inverted test tube from bottom to top;
in the rotation process of the tubular shaft 1, when the channel on the outer ring 181 rotates to the position on the inner ring 182 corresponding to the groove communicated with the high-pressure water pipe 20, the high-pressure water pipe 20 can provide high-pressure moisture into the transmission pipe 13, and when the channel on the outer ring 181 rotates to the position on the inner ring 182 corresponding to the groove communicated with the hot air pipe 19, the hot air pipe 19 can provide hot air for the transmission pipe 13, so that the cleaning, the disinfecting and the drying can be continuously carried out, and the two functions are smoothly switched;
meanwhile, water or air can flow through the inside of the rotatable telescopic brush rod 10 with the hollow structure, so that the rotatable telescopic brush rod 10 can provide spray washing while brushing, and after the washing is finished, the hot air pipe 19 can be matched with the brush rod to provide hot air sterilization and drying functions; (ii) a
The tubular shaft 1 rotates continuously, and when the radial turnover mechanism 7 rotates to the position of the other arc-shaped rack 4 in the machine shell 9, the test tube can be driven to turn over for 180 degrees again, so that the test tube returns;
when the test tube swivelling movement released conveying belt machine 8 position to the test tube, because the test tube is blocked by direction splint 84, and the test tube is continuous to be driven rotatoryly by hollow shaft 1, thereby can be gradually shifted out and overturn anchor clamps 5 by the extrusion, get into between the conveyer belt body and the direction splint 84, the rotation of the conveyer belt body is pushing away the test tube and is removing, rely on frictional force to let the test tube can not drop downwards, the messenger is pushed to the test tube rack 83 by the test tube of centre gripping, the completion is collected the test tube automatic arrangement who washs the completion, the user takes out the test tube that washing disinfection stoving was accomplished from the test tube rack 83 can.
