[0002] A tubular screw conveyor is a continuous conveying device that uses a rotating screw to move materials. It consists of a closed tubular shell with a rotating screw inside, and is suitable for conveying loose materials such as powders, granules, and small pieces.

[0003] The patent document with application number CN202122947203.X discloses a tubular screw conveyor, which includes a first conveying shell, which is detachably connected to a second conveying shell by bolts, and a spiral body is provided in the first conveying shell and the second conveying shell, and flanges are fixed at both ends of the spiral body, and adjacent flanges are detachably connected by bolts. A bearing device is installed at the right end of the second conveying shell and the bearing device is connected to the flange on the right spiral body. A coupling is installed on one side of the bearing device, and a reducer is connected to one side of the coupling and a motor is installed on the reducer. The utility model facilitates the adjustment of the height of the tubular screw conveyor through the adjustment structure, and can adjust the height according to actual usage conditions, with better flexibility.

The blocking mechanism 2 also includes a support rod 204, a threaded seat 205, a pitch-adjusting screw 206, a rotating handle 207 and a clamping disc 208. The upper end of the limit frame 203 is fixedly mounted with a support rod 204, the upper end of the support rod 204 is fixedly mounted with a threaded seat 205, the inner side of the threaded seat 205 is threadedly connected with the pitch-adjusting screw 206, the upper end of the pitch-adjusting screw 206 is fixedly mounted with a rotating handle 207, a clamping disc 208 is provided below the pitch-adjusting screw 206, and the clamping disc 208 is fixedly mounted on the upper end of the blocking horizontal plate 201;

[0026] The adjustability of the barrier cross plate 201 enables it to be accurately positioned in the tubular screw conveyor bin 1, which can effectively isolate the area that needs to be cleaned and prevent the detergent and sponge ball from entering the undesignated cleaning area, thereby improving the pertinence and efficiency of the cleaning operation. The leak-proof rubber plate 202 is arranged below the barrier cross plate 201, which can prevent the detergent and sponge ball from leaking, ensuring that the detergent and sponge ball completely act on the area above the barrier cross plate 201, thereby improving the cleaning effect.

[0027] The displacement mechanism 3 includes a mounting plate 301, a limiting slide rail 302, a drive motor 303, a displacement screw 304 and a displacement slider 305. The limiting frame 203 is fixedly mounted on the displacement slider 305. The upper surface of the tubular screw conveyor bin 1 is fixedly mounted with a mounting plate 301.

The left end of the mounting plate 301 is fixedly mounted with a drive motor 303. The transmission end of the drive motor 303 is mounted with a displacement screw 304. The displacement screw 304 is threadedly connected to the displacement slider 305.

[0028] The mounting plate 301 provides a solid mounting base for the displacement mechanism 3. The limiting slide rail 302 provides guidance and limitation for the displacement slider 305, ensuring the linear motion of the displacement mechanism 3 during the cleaning process. The drive motor 303 provides power for the displacement mechanism 3. By driving the rotation of the displacement screw 304, the linear motion of the displacement slider 305 is achieved, thereby achieving the lateral displacement of the blocking mechanism 2. The displacement screw 304 converts the rotational motion of the drive motor 303 into the linear motion of the displacement slider 305, so that the blocking mechanism 2 can move laterally in the tubular screw conveyor bin 1, thereby achieving comprehensive cleaning.

[0029] The working principle of the present invention is as follows: the tubular screw conveyor is additionally provided with a blocking mechanism 2 and a displacement mechanism 3. Before using the tubular screw conveyor, the tubular screw conveyor bin 1 needs to be installed and fixed in advance, and the screw motor 6 and the drive motor 303 need to be powered and connected to the control terminal. When using the tubular screw conveyor, the screw motor 6 is started to drive the rotating rod 4 and the spiral piece 5 to rotate, and the material conveying operation can be performed. After the feeding operation is completed, the cleaning operation is performed to maintain the tubular screw conveyor. First, a certain number of sponge balls are filled into the tubular screw conveyor bin 1 through the feed port 7, and then detergent and water are input. The blocking mechanism 2 is activated, and the pitch-adjusting screw 206 is rotated downward so that the blocking cross plate 201 is inserted down above the rotating rod 4 and located on the inner side of the spiral piece 5. At this time, the screw motor 6 is started to drive the rotating rod 4 and the spiral piece 5 to rotate, which will drive the sponge balls and cleaning solution to accumulate on the blocking mechanism. On one side of the partition cross plate 201, in this state, the sponge ball and the cleaning solution will continuously rub and clean the spiral blades 5 and the inner wall of the tubular screw conveyor bin 1. After completing the cleaning operation within this range, the displacement mechanism 3 is activated, and the drive motor 303 is started to drive the displacement screw 304 to rotate, thereby driving the displacement slider 305 and the blocking mechanism 2 on the displacement slider 305 to perform displacement operations, thereby achieving a positioning effect; in summary, the blocking mechanism 2 and the displacement mechanism 3 complement each other, and the blocking mechanism 2 adopts an adjustable blocking structure and is used in conjunction with the sponge ball. It can quickly clean the rotating rod 4, the spiral blades 5 and the residue on the inner wall of the tubular screw conveyor bin 1, thereby achieving a cleaning effect of the tubular screw conveyor bin 1. In addition, the displacement mechanism 3 adopts a screw linear transmission structure, which can drive the blocking mechanism 2 to displace, thereby performing a comprehensive cleaning operation on the tubular screw conveyor bin 1.
