Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0021] like Figure 1-4 The utility model discloses a screw conveyor with a cleaning function, comprising a base 1, a screw conveyor 2 is arranged on the base 1, a screw rod 3 is rotatably arranged in the screw conveyor 2, a conveying driving device 4 is arranged on the screw conveyor 2 and is connected with the screw rod 3, a fixing frame 5 is arranged on the base 1, a flushing device 7 is arranged in the fixing frame 5 and the screw rod 3, and a locking device 6 is arranged on the flushing device 7;

[0022] like Figure 1-3 The flushing device 7 includes a water tank 8, which is arranged on the base 1, and a rotating joint 9 is provided on the fixing frame 5. A water pipe 10 is provided between the rotating joint 9 and the water tank 8, and a water pump 11 is provided on the water pipe 10. A through hole 12 is provided in the spiral rod 3, and a hollow cylinder 13 is provided for rotation in the spiral rod 3. The other end of the hollow cylinder 13 rotates in the rotating joint 9, and water outlet holes 14 are provided in the hollow cylinder 13 and correspond to the through holes 12 one by one. The through holes 12 are provided in multiple groups around the spiral rod 3 and the number is the same as that of the water outlet holes 14 on the hollow cylinder 13. By rotating the position of the hollow cylinder 13, the water outlet holes 14 can be aligned with the through holes 12, so that water can be sprayed out from the through holes 12 to clean the spiral rod 3.

[0023] like Figure 1 and 4The locking device 6 includes a bracket 15, which is fixed to the hollow cylinder 13. The bracket 15 is internally threaded and provided with a locking screw 16. A hand wheel 17 is provided at the upper end of the locking screw 16. A pin hole 18 is provided on the spiral rod 3.
