[0016] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0018] like Figures 1-5 As shown, a water retaining mechanism for a kitchen spiral conveying system comprises a bearing seat 2, one side of the bearing seat 2 is connected to a reducer 1 by bolts, and the other side is connected to a conveying cylinder 3 by bolts, and an output shaft 4 on the reducer 1 is rotatably connected to the bearing seat 2, a first shaft cavity 14 is provided on an end cover of the bearing seat 2 adjacent to the reducer 1, and a second shaft cavity 15 is provided on an end cover adjacent to the conveying cylinder 3, the output shaft 4 is rotatably connected in the first shaft cavity 14 and the second shaft cavity 15 through a bearing, and a plurality of connecting rods 16 are evenly arranged around the circumference of the axis of the first shaft cavity 14 between opposite surfaces of the end covers on both sides;

[0019] The output shaft 4 is provided with a card slot 5, and a water retaining ring 6 is detachably installed on the card slot 5. The water retaining ring 6 includes two semicircular half water retaining rings 7, one end of the half water retaining ring 7 is provided with a slot 8, and the other end is provided with a first through hole 9, and the slot 8 is provided with a connecting piece 10 vertical to the half water retaining ring 7, and the connecting piece 10 is provided with a second through hole 11, and the two half water retaining rings 7 are staggeredly sleeved in the card slot 5, and the two first through holes 9 are connected and fixed by through bolts, and the second through holes 11 on the two connecting pieces 10 are connected and fixed by through bolts, and the connection between the water retaining ring 6 and the card slot 5 is coated with sealant, and the water retaining ring 6 is placed in the connecting rod 16, and the diameter of the water retaining ring 6 is larger than the outer diameter of the first shaft cavity 14;

[0020] A sealing mechanism is provided at the connection between the output shaft 4 and the bearing seat 2 near the conveying cylinder 3. The sealing mechanism includes a packing, a packing groove and a packing gland 18. The packing groove is provided on the bearing cover in the second shaft cavity 15. The packing is wound around the output shaft 4 and placed in the packing groove. The packing gland 18 is sleeved on the output shaft 4, and one side is inserted into the second shaft cavity 15, and the other side is fixed to the inner wall of the second shaft cavity 15 by bolts to compress the packing.

[0021] A shell 17 is detachably mounted between the end covers on both sides of the bearing seat 2, a water collecting box 12 is detachably mounted on the bottom of the shell 17, a drain outlet 13 is provided at the bottom of the water collecting box 12, flange plates are provided on both sides of the shell 17, and are fixed to the end covers on both sides of the bearing seat 2 by bolts, an opening is provided at the bottom of the shell 17, a mounting frame 19 is provided in the opening, the water collecting box 12 is fixed in the mounting frame 19 by bolts, and the drain outlet 13 at the bottom of the water collecting box 12 is connected to the ditch through a corresponding pipeline.
